Bezif Electro Sleep


The electro sleep apparatus is based on SOMLEC therapy introduced by Russia. The best results are seen in those patients with increased psychomotor activity, ie. Anxiety states, Tension state, Insomnia,Hysteria, Obsessional neurosis, Phobic states & Hypocondraises etc.


A Treatment room where the patient will not be disturbed, should be used & it is an advantage if curtains are used to darken the room. No special preparation is required & normal meals may be taken before treatment.


Patients should be instructed to prepare themselves as if for a normal sleep, ie. Bladder should be voided. At the first treatment the patients should be told to make themselves as comfortable as possible & to adopt their normal attitude in bed for sleep. It should be well explained that they will experience no pain with the treatment ,but will only feel a slight tapping sensation on their forehead. They should be told that the treatment will make them feel very relaxed & that they will gradually become drowsy & finally enjoy a relaxing sleep.


Two Electrodes with red wire are to be fixed just above eyebrows & the single one with black wire at the rear central position ( Inion point ) with soft valcro tape. Jelly should be used for better contacts.


The Apparatus must be checked to ensure that intensity control should be at zero position. Plug the main lead to 220V AC mains socket & switch on. The indication comes through a pilot lamp.


The Intensity control is then very slowly turned from minimum & the patient is asked to tell as he can feel the tapping sensation on the forehead. With the patient's co-operation the intensity control should now be increased to the level at which the tapping sensation is more noticeable, but not so strong that it is unpleasant. The treatment thus continues for 1.5 to 2 hours during which the patient requires no supervision.


At the end of the treatment period , the intensity control is slowly brought to minimum. Very few patients sleep at the first treatment due to apprehension but the majority sleep well after the 3rdfew only achieve sleep after 7-8 treatments.


Treatment should be given everyday. The course of treatment depends on each individual case & the response obtained, but will normally be a minimum of 15-20 treatments .After treatment remove the electrodes & clean them.


SPECIFICATIONS:

Intensity-0 to 30 v

Frequncy- 40 Hz


Useful in INSOMNIA, ANXIETY, TENSION & MIGRAINE problems.


  • Two electrodes on forehead & one at rear central with valcro tape.

  • Patient feels ting-ling nominus over forehead which helps him/her to sleep.

  • 10 to 15 sessions required, & each session duration is 40-60 minutes.



Bezif Brain Polariser


Brain Polariser is used for the cases of Depression even where ECT & drugs fail to give results. It increases the alertness, mode elevation & a feeling of well being.


A treatment room/bed where the patient will not be disturbed , should be used. Patients may take their meals before treatment. It should be well explained to them that they will experience no pain but will only feel a slight sensations of pulses on their forehead & gradually in whole body. They should be well informed that the treatment will make them feel very relaxed & depression free.


Two Electrodes with red wire are to be fixed just above eyebrows & a single one with black/green wire at the right sole. Jelly should be applied for better contacts.


The Apparatus must be checked to ensure that the intensity control should be at zero position. Plug the main lead to 220V AC mains socket & switch on. The indication comes through a pilot lamp.


The Intensity control is then very slowly turned from minimum & the patient is askedto tell as he can feel the slight sensations of pulses on the forehead. With the patient's co-operation the intensity control should now be slowly increased to the level at which the sensations are more noticeable but not so strong that it is unpleasant. The treatment continues thus for 40 to 60 minutes during which the patient requires no supervision.


At the end of treatment ,the intensity control is slowly brought to minimum. And day by day go on reducing the intensity a little bit.


Treatment should be given everyday or 5-6 times a week. The course of treatment depends upon individual cases & the response obtained , but will normally be a minimum of 12-15 sessions. After treatment remove the electrodes & clean them.


SPECIFICATIONS:

  • Useful in DEPRESSION even where ECT & drugs fail.

  • Two electrodes on forehead & one at right sole , fixed with valcro tape.

  • Intensity from 0 to 10 V.

Neurons are polarized with the circulation of pulses which allow to produce serotinine Which controls the depression level.



Bezif Aversion Therapy


It produces adjustable painful stimulus due to which the response of irritation occurring to sight/ smell/taste of addictive is produced. It is a 15 days indoor treatment where repeated pairing of electrical stimulus is applied to the addictive in order to make him avert from sight/smell & taste of alcohol.


The valcro tape electrode (whose big socket is in back side) is easily fixed either on arm or leg. Adjust the intensity with the control to a level which is unpleasant but not very painful to the subject. Start from minimum & then go on increasing the intensity & test the unpleasant stimulus.


The addictive is applied the aversive stimulation while looking at or starting to drink & while taking a sip of the alcohol. The stimulus is applied for the short time only say in milli seconds. The light indicator glows as & when treat switch is pressed. The small EP socket on front panel named REMOTE is for the remote switch to be pressed to apply stimulus.


To apply the stimulus remote control switch should be used so that subject should not be able to analyze the operator's activities. Thus repeating treatments condition the mind to think that ,doing the bad habit, will hurt him.


The instrument can be made more successful if it is supplemented by more adaptive measures, counseling & family support.


The 9V 2 small size batteries connected parallel are used inside the instrument, which is available everywhere costing each 10 Rs. Only. The system to replace the battery is very easy through tich buttons. To remove the batteries open the two covers at the bottom of the instrument. The 9V adaptor pin is to be inserted in the small EP socket in the backside adjacent to Main switch.

SPECIFICATIONS:

  • Useful in De-addiction from wine.

  • 9 V battery/ 9V adaptor operated.

  • Intensity from 0 to 100 V to avert from sight, smell & taste of alcohol.


Minimum 15 days indoor treatment.



Bezif Vacuum Therapy


Our ERECT AID Vacuum Therapy Machine is fully automatic motorized system to create adequate suction.Vacuum Therapy is a safe and non-surgical means of helping a man produce erections. It does not require medications, injections or surgery.in treating erectile dysfunction due to many different causes.


An erection is achieved by first, placing the male organ in a vacuum cylinder, creating a vacuum which generates blood flow into the organ, which causes enlargement and rigidity. The natural erection is held by support ring, which restricts the flow of blood back out. Using the system, the erection can be safely maintained for up to 30min.


Vacuum therapy is a popular solution to the problem of erectile dysfunction.


How Does A Penis Erectile Dysfunction Pump Work?

  • The user expands the penis ring over the bottom of the plastic cylinder.


  • To promote a proper suction seal, lubricant is applied to the base of the penis, bottom of the plastic cylinder and inside the tube to allow the penis to easily be drawn into the tub once suction is applied.


  • The penis is inserted into the tube and the tube is pushed against the base of the penis and body to create a proper seal.


  • Suction is initiated by automatic pump.


  • As negative pressure develops the penis is engorged with blood and an erection is achieved.


  • After the erection is achieved the elastic penis ring is slipped off the tube to the bottom of the shaft of the penis and the erection is maintained.


  • The plastic cylinder is removed for intercourse.


It is to be used under the prescription of a Registered Medical Practitioners. The manufacturer disclaim any responsibility or liability, in connection with the use of this product.

Bezif Audio Visual Reaction Timer


Simple Reaction Time


Problem


To determine simple reaction time of the subject for visual stimuli.Introduction


In 1786 Maskelyne, Royal Astronomer at the Greenwich Observatory, dismissed his assistant, Kinnebrooke,who observed the times of star movements almost a second later than he did. Such an error was considered unpardonable because the calibration of clocks to determine the standard time depended on the correct observation of the place and time when the stars were seen. It was not until 1819 that a personal difference was discovered by the German astronomer, Bessel,who found an average difference of 1.041 seconds between him and another observer. Kinnebrooke's error was of the order of 0.8 second. This difference came to be called the personal equation, and was found to very with different individuals between 0.770 and 1.021 seconds. In order to minimize errors due to this personal equation, the chronograph and chronoscope were invented. By 1892,the Hipp Chronoscope was brought into use . This timing device measures time intervals in thousandths of a second, or milliseconds. Eventually , it was realized that at the human level, there is a measurable time lag between the appearance of a signal and the response to it . Research in experimental psychology has , since that time, made great strides forward in the exact measurement of what today goes by name of Reaction Time or response time.


One of the classical experiments of the psychological laboratory concerns the speed with which a stimulus elicits a response. The reaction time experiment has had a long history and still is a standard procedure in experimental psychology. It has remained a sensitive measure of the readiness of the organism or preparedness varies both with the stimulus situation as well as the sets and attitudes of the organism. "Time ", as woodworth says," as a dimension of every mental or behavioural process, lends itself to measurement, and can be used as an indicator of the complexity of performance or of the subject's readiness to perform…


Faulty procedures have been tried and found Unworkable, problems hopefully attacked have been found insoluble by the use of reaction time , and the reasons for these failures , as well as the sucesse's are really quite important contributions to the science of psychology". In the simple reaction time situation, the observer is instructed to respond to a single stimulus by withdrawing his finger from a key as soon as possible . The sense modality stimulated is an important parameter of every reaction time experiment. Speed of response varies with different sense modalities, as will be evident in Table


Typical Ranges of Simple Reaction Time


Sense Modality Range in ms
Touch (pressure stimuli) 110 - 150
Hearing (sound stimuli) 120 - 160
Vision ( Lights ) 150 - 200

Within any given sense modality, reaction time varies considerably with the specific characteristics of the stimulus. An intense stimulus produces a response of greater magnitude in the sense organ a weak stimulus. In the case of visual stimuli, effective stimulation depends not only on the intensity of the stimulus, but also on duration, size and location of the area stimulated. Increases in duration of visual stimuli and the area of visual stimulation also shorten reaction time. The correlation between speed of reaction and effectiveness of stimulation appears also when the observer responds to change in the level of stimulation. The greater the change introduced in the experiment, the faster will be the reaction time. Reaction time to change is faster at a medium level of intensity than at a low level , but slower at a high level than at a medium level.


This system is used in various Psychological institutes to detect reaction time of the persons. Some where it can be used as IQ testing instrument also. There are two sides in the instrument-Experimentor side & Trainer side.A sheet seperates the two sides.There are two modes of functions- Light & sound. Any of these two functions can be selected by mode switch. There are four switches as well as four no.of L.E.D's on both the sides. The switches in the Experimentor side are to glow the lights, whle,the switches in Trainer side are to OFF the lights.First select the light mode & glow any light among the four & Trainer is asked to keep it OFF as quickly as he can do. The time taken by him is measured in LCD meter ie known as his reaction time.Similarly in 2nd mode ie sound mode start any sound using the same switches & ask the Trainer to keep the sound OFF immediately.Experimentor may change the mode of operation among. audio & visual through switch any time & many time during the whole test.The minimum time taken by the Trainer to OFF light/sound is called good reaction time.


Area of application: psychologist or psychiatrist uses this instrument for general IQ test of the person. This system is used in psychological institutes / hospitals to check the reaction test of the persons. In this system there are two sides- one isoperator's side & the other is trainer's side. There are 4 switches & 4 no. of lights on both sides.The switches in operator's side are responsible to glow the lights w hile the switches in trainer's side are to turn off the lights. Glow any light quite a sudden & ask the trainer to react the action & turn off the light imme diately from it's side. The time taken by the trainer is called reaction time & that is noted down in the timer.


Similarly in the 2nd mode there are 4 different melodies /tones. The operator will start any sound & the trainer is to turn it off immediately in the shortest time.Thus the operator can operate any f unction from light or sound & trainer is to react very fast to turn the same off.


The minimum time taken by the trainer to react is estimated as good reaction time. Features


  • Modes of Operation- light and sound.
  • Functions for light &sound 4 for each.
  • LCD display for counting of Reaction Time.
  • Soft touch switches.

Bezif Flicker-fusion


Application :


Assessment of the central-nervous activation (arousal) with the help of threshold values, when high frequency light is recognized as constant light. To be used with adults.


Main areas of application: clinical psychology, neuropsychology, medicine and harmacology. Physiological studies prove that the activation (arousal) of the organism is centrally controlled. The flicker fusion frequency is regarded, next to other criteria as on indicator for this central-nervous function capacity.


Working: :


In the increasing process the frequency of a flickering light is augmented until a constant light is perceived: In the decreasing process the frequency of a higher frequency light, that the respondent perceives as constant, is reduced until it is subjectively perceived as flickering. The respondent has to confirm every change of perception by pressing a key. The critical frequency is than stored.


The median values of the critical frequencies in the ascending or descending process are threshold values and they are caleld "Fusion frequency (VF)" and "Flicker frequency (FF)"


Features :


  • Fusion frequency- 5 to 70Hz.


  • Frequency in Ascending and Descending mode.



  • Two color light facility- Red & Green.


  • Auto mode.


  • LCD Display for frequency counts.


  • Mains operated.



Bezif Tachistoscope


Introduction:

Tachistoscope is an instrument projects a series of images on to a screen at rapid speed to test visual perception, memory & learning. The US Air Force originally used tachistoscopes to help pilots identify aircraft by gradually reducing the size and time of flashing images. This technique was then adapted to reading by flashing words. Shortening perception time only produced improvements for reading while the exercises were maintained. The name is derived from the Greek :tachys"(swift) and "scope"(seeing) literally "rapid seeing".


An apparatus used for briefly viewing a screen bearing letters or figures. It is used in studying the range attention or the power of distinguishing separate objects in a single impression.


Features:

  • Stim time for display of light on screenfrom 0.1 to 6.0 sec.


  • 15 spare slides comprising of words.


  • Slide box detatchable.


  • LED bargraph system in slide box.


  • Digital timer to select time.


  • slides in plastic material.



Bezif Depth perception


Depth perception is an instrument to test the driving aptitude of the drivers how he perceives the vehicles in three dimentions.There are three rods of same height.The two rods on both ends are fixed permanently while the middle rod is movable forward & backward at two speeds.The subject sits at a distance of 2.5 meters away from the unit & looks the rods through a window. The deviation from straight alignment of the three rods which the subject assumes to be correct is read on the manual scale as well as on LCD meter.The unit is illuminated by CFL light.


SPECIFICATIONS:-

  • Movement of rods with remote box switches.


  • Provisions of 2 speeds 25mm/sec & 50mm/sec.


  • Distance between rods 30mm left or right from movable rod.


  • Range of movable rods ± 180mm.


  • Manual scale rating ± 200mm


  • Length of remote switch wire 1.5 mtr.


  • CFL light 8 watt in the box.


  • Power 220v AC.



This device consists of two rods suspended within an enclosed housing that contains its own lighting systems to provide uniformly diffused illumination. The rods are adjustable back and forth by means of a cord set attached to the rod guides.The unit has been constructed such that external depth cues are eliminated, requiring that a subject make depth discriminations on the basis of binocular or monocular vision cues alone.The unit is designed to test acuity of depth perception, and has had a long history of development. Its earliest appearance is found in the famous three-needle experiment designed by Helmholtz (1856- 1866). Howard, in 1919, revised the design by using only two rods instead of three, making each rod moveable and allowing Subject (S) to adjust the rod designated the comparison. These two rods are seen through an aperture to eliminate extraneous cues. This apparatus became known as the Howard- Dolman Apparatus, and was used to screen aviation candidates for poor steropsis. The present apparatus has been further refined by completely enclosing the rods within a housing and providing a uniform and diffused lighting system. The rods have been connected such that the S moves both rods simultaneously in opposite directions. The scale on top of the housing is graduated in centimeters. The pointer gives the distance each rod has moved away from center; therefore, to obtain the total distance between rods, it is necessary to double the indicated value.


Bezif Bassin Anticipation


Features:-

  • "10 Lights at 1" distance on runway.


  • Light's velocity range 25,50,75,100,150,175.km/hr.

Application

The application of Bassin Anticipation Timer is to test the area of human visual activity related to eye-hand co-ordination & anticipation.It is very useful to test & train the visual skill of athletes & players.


Operating Procedure

The instrument consists of a track along which runs a sequence of LEDs & one target LED.The subject is instructed to watch the light as it travels down the runway.They must anticipate the light reaching the target & press the push switch to coincide with the arrival of light at the target.The test can be performed at different speeds of light provided.As the ability improves, the speed is also increased.


Bezif Steadyness Tester


Introduction:

Writer's cramp is a task specific focal dystania of the hands (steadiness tester). Writer's Cramp typically affects the person's dominant side, meaning the writing hand. It is often characterized by an abnormally pronounced, forced grip on the writing instrument. This may occur immediately upon. Grasping the pen or pencil or shortly after beginning to write. Less commonly these may be excessive extension of the fingers that causes the writing instrument to drop from the hand. Additional finding may involve certain muscles of the end shoulder, writing may be laborers and shaky with discomfort or pain in the forearm. Some people are not able to write even after just a few words.


Symptoms usually appear when a person is lying to do a task that requires fine motor movement. The symptoms may appear during a particular type of movement such as writing or playing a piano, but the dystonia may spread to affect many tasks.


This is a physical method to help the patient write in cramp included learning to hold the pencil with the help of a special numeric board. In this method the subject is asked to hold a metal tipped stylus and move through the grooves, which are in shape of (alphabets/numeric) letters without touching the sides. The indicator (led/beep) gives the signal every time the stylus touches the copper plate. Reduction in number of errors for successive trial is useful demonstration of learning.


The approach for treatment is usually three tiered: oral medication, botulinum toxin injections, and surgery.


Features:

  • Separate writing unit comprising of Alpha Numeric.


  • Plastic hand held probe.


  • Velcro tape electrode.


  • Buzzer facility for wrong detection.


  • Battery operated.


  • Light weight.



Bezif Transcranial Direct Current Stimulation


A non-invasive and safe neurostimulation therapy for the treatment of depression, obessive- compulsive disorder, migraine, and chronic pain.


Transcranial Direct Current Stimulation (TDCS):


A new neurostimulation therapy


Transcranial direct current stimulation (TDCS) is a new form of neurostimulation that may be used to safely treat a variety of clinical conditions including depression, obsessive-compulsive disorder, migraine, and central and neuropathic chronic pain. TDCS can also relieve the symptoms of narcotic withdrawal and reduce cravings for drugs, including nicotine and alcohol. There is some limited evidence that TDCS can be used to increase frontal lobe functioning and reduce impulsivity and distractibility in persons with attention deficit disorder. TDCS has also been shown to boost verbal and motor skills and improve learning and memory in healthy people.


Transcranial DC stimulation uses only very small electric currents that cannot set off a seizure and is far more selective in its effects. TDCS only influences the area of the cortical brain directly beneath the electrode.


Transcranial DC stimulation may be done in the doctor's office with the patient sitting in a comfortable chair. The basic treatment consists of a series of five 20-minute sessions over five consecutive days, Monday through Friday. Sometimes a second series of five treatments may be necessary to obtain maximum improvement in symptoms being treated.


Illustration of a patient being treated with TDCS.

While the patient is seated in a chair, two 5 cm x 5 cm non-metallic conductive rubber electrodes are placed on selected locations of the scalp and covered by saline soaked sponges and held in place by elastic headbands. After the electrodes are properly placed, a TDCS device powered by a 9-volt battery is used to send a steady electrical current of 1-2 microamps through the electrodes and into the cortex for 20 minutes.


The electrode attached to the positive (anode) pole of the battery will excite neuronal activity in the cortex under it, whereas the electrode attached to the negative pole (cathode) of the battery will inhibit neuronal activity in the cortex under it.


The procedure does not elicit any pain. Patients receiving TDCS generally report nothing more than a mild tingling or itchy feeling from under the electrode during the stimulation. These sensations disappear immediately after the current is turned off.


Treatment with TDCS is relatively inexpensive, easy to administer, non-invasive, painless, and safe.


Treating Chronic Pain With Direct Current Stimulation


Bezif Cranial Electro stimulator


Anxiety

Cranial electrotherapy stimulation (CES) has been used as a treatment for anxiety in several parts of the world for over a quarter of a century. American medicine has only recently begun to realize its use as a safe and effective treatment. Studies show that cranial electrotherapy treatment yields highly significant reductions in anxiety, whether the patients were in a psychiatric setting, a scholastic setting, an outpatient setting, or an inpatient general hospital setting. Further,while many different kinds of anxiety have been studied, they all responded significantly to CES treatment.


This kind of anxiety typically is not reduced significantly in fewer than 2 or 3 weeks of daily treatments.


Depression


Studies show that reactive depression (that which results from acute changes in the patients life situation such as a job change or divorce) is decreased after 6 days of cranial electrotherapy treat- ment. More deep seated depression (endogeous) in some cases required 3 or more weeks of daily treatment. For this reason, many physicians routinely prescribe a minimum of 2 weeks to a month of daily cranial electrotherapy treatments in depressed patients, Other research has shown that cranial electrotherapy, when used this way is neither habit forming nor addictive. Such patients use it only when they experience an impending medical necessity.


Migraine

Pulses of .5 ms from .5 to 100 Hz generates serotonin & production of endorphin for pain relief. The best results are seen in 3 to 15 days.


Insomnia

Because cranial electrotherapy was originally called 'electrosleep' in European countries, many other American studies were designed to learn whether or not such small amounts of electric currents would actually put people to sleep.That is, just as 50 ma of current -called 'electro- anaesthesia'-put an indi- vidual into anaesthesia so that surgical procedures could be performed, 1ma of Cranial Electrotherapy current was assumed to put them into a normal state of sleep if 'electrosleep'worked. Such studies discovered that while cranial electrotherapy does not necessarily'put a person to sleep'it does accom- plish some very therapeutic changes in the sleep patterns of people who complain of insomnia.


Treatment parameters:- While some patients begin to respond after the second or third day of treat- ment, others do not have their best response with fewer than 14 days of treatments lasting from 15- minutes to `1'hour.The beneficial effects have been measured in some experimental groups for as- long as two months.Some people with insomnia have a habitual pattern of responding to situational - stress with an interruption in their sleep patterns.
