PHYSIOGRAPH

  • Single & Three (2+1) Channel
  • Easy to operate-even by a beginner
  • Designed on the concept of couples for specific recordings
  • High sensitive
  • Rugged
  • Versatile
  • Accurate
  • Reliable
  • Low Cost
  • Time & Event Channel (Optional)

STUDENT PHYSIOGRAPH is used for the recording of Bio-Electrical Potential e.g. EEG, ECG, ENG, EMG, Pulse, Respiration, Blood Pressure etc. It is made of light metal for compactness and lightness. Its performance is outstanding due to adoption of integrated circuits.

Each unit is so designed that a trouble free, simple and precise operation is possible. Appearance is very smart and compact for ease of carrying.

 

STYDENT PHYSIOGRAPH comprises of:

Main Console

Couplers

Transducers

Accessories like electriode.

 

Main Console

 

The main console houses

Chart Drive

Ink Pen recording system

Main Amplifier

Housing for plug in couplers

 

Electronically controlled 9 chart speeds provided are .5,1,2,5,10,20,25,30 & 50 mm/sec. Any other speeds are provided against specific requirements.

 

Speed selection is easy and instantaneous.

Channel width is 70 mm

Ink writing pen is 120 mm in length to minimise arc distortion.

The main Amplifier is fitted in the console having switch selectable sensitivity range from 50 microvolts per cm to 100 millivolts per cm in eleven steps as 50,100,200,500 µv/cm and 1,2,5,10,20,50,100 mv/cm

 

 

Couplers:

 

Different couplers are designed to record different parameters. They are modular interchangeable in the same console or from console to console and one can easily plug them in or out in few seconds. The standard range of couplers is as follows:

 

Biopotential Coupler

For recording all AC phenomena like ECG, EEG, EMG,ENG etc. It is supplied with 3 pin junction box, EEG-EMG electrodes and paste etc.

 

 

EKG Coupler

For recording clinical ECG. It is supplied with 5 pin junction box, Limb & Chest electrodes and Jelly.

 

Straingage Coupler:

For recording from all straingage transducers and used to record muscle activity force, effect of drug on heart activity, Blood pressure from cannulated animals, volume changes etc

 

 

Pulse-Respiration Coupler

For recording pulse or respiratory activity using pulse, respiration Belt or respiration transducers.

 

Temperature Coupler:

For recording internal or surface temperature through transducers.

 

Isotonic Coupler

Using it along with isotonic fine movement transducer one can perform experiment on isolated uterus and isolated intestine

 

TRANSDUCERS

 

A Transducer is a device which converts one form of physical energy to electrical energy or vice versa. To record parameters which are not available in electrical form e.g. Pulse, Respiration, Temperature, Phono Cardiogramme etc., one needs to use appropriate transducer. We manufacture following transducers.

1.Pressure 2. volume 3. Muscle Activity/ Force. 3. Respiration Belt Isotonic Fine Movement. 4.Pulse . 5. Respiration (Thermistor). 6. Temperature Internal,  7. Temperature Surface,

 

Physiograph Stimulator – Optional

A turn controlled pulse Generator

MODE: SINGLE, External & Repetitive

PULSE WIDTH : 0.5 and 1.5 ms Switch selectable

Repetitive Frequency : 0.5,1.2,3,5,7,10,15,20,50 & 100 Hz

Twin Pulses: Provided. Delay adjustable from 5 to 250 ms

Output Voltage: 0 to 30 Volts (Two position 0-3 & 0-30 volts vernier controlled)
