SIP385 Biomedical Instrumentation

The course contains two prewired panels with a variety of cables and accessories. It provides training in basic monitoring circuitry, such as ECG, EEG, EMG, pulse rate, GSR, and temperature monitors. Safety is stressed in the program, and live measurements can be made on students. The course provides for approximately 75-100 hours of instruction.

EQUIPMENT SPECIFICATIONS
SIP385B-1P Biomedical Instrumentation Panel
Consists of the following sections:

SECTION DESCRIPTION

A Differential Amplifier:

bullet

Common Mode Rejection Ratio (CMRR): 80 dB

bullet

Gain: 120 dB

B Differential Amplifier with Sensitivity to 5 mV

bullet

Frequency Response:
bullet

DC to approximately 1 KHz

bullet

Low-Pass and High -Pass Filters provide required frequency responses for ECG or EEG

bullet

Input Safety Devices limit input voltage for protection against line power

bullet

Control Switches for varying rolloff frequencies and amplifier gain

C Optocoupler isolates the front end amplifier and reference ground from earth ground circuitry

D Signal Processor provides gain for such signals as the R wave in an ECG signal

E 60 Cycle Notch Filter can be switched in or out of the circuit to provide 50/60 Hz trapping

F 8-14 Hz Amplifier is designed to provide bandpass for signals in the 8-14 Hz region

G Output Amplifier provides additional gain for recording various physiological signals

H Isolated Power Supplies to isolate the front end amplifier from the common earth ground
supply (provides an additional margin of safety)

I Polarity Correction Circuitry enables the R wave to be either positive or negative; the output
is always a positive signal

J Pulse Stretching Circuit uses the R wave as the signal and converts it into a rectangular pulse

K Tone Generator produces the tone whose on period is controlled by the Pulse Stretcher Circuit

SECTION DESCRIPTION

L Integrator Circuit

bullet

Converts the pulse stretched signal into a DC level for the 1 mA meter

bullet

Pulse Rate is read on a calibrated meter

The Panel operates from the Power Supply Base (S300PSB).

SIP385B-2P Biomedical Instrumentation Panel

bullet

Pulse Generator uses photoplethysmography

bullet

Direct Digital Readout of Pulse Rate

bullet

Temperature Control Circuits with digital display, accurate to 0.10° Centigrade or Fahrenheit, switchable

bullet

Galvanic Skin Resistance (GSR) with signal test button and variable gain control

bullet

Signal Amplifier and gain control

bullet

VCO controlled Light and Sound Bar for audiovisual effects

bullet

GSR Circuit responds to sweat radiation on the hand (special Electrodes and cable are provided)

ACCESSORIES

bullet

Lead Selector Box for selecting Leads #1, #2, or #3 during ECG measurements

bullet

Set of ECG electrodes and straps, along with 5 terminal connector between the leads and the ECG box

bullet

Pulse Rate Probe

bullet

EEG Cable with 4 electrodes

bullet

Temperature Sensor Cable

bullet

Alcohol Pads and Temperature Sheaths

The Panel operates from the Power Supply Base (S300PSB) or the Panel Base (S300PB).
