Blood pressure is the pressure the blood exerts on the walls of the blood vessels. The measurement of blood pressure is reported with two numbers, a systolic and a diastolic number. The systolic number is the top number, which is the pressure on the vessels when your heart is contracting. Because the heart is contracting, the force of the blood flow is higher. Labtech Blood Pressure Training Unit is designed to demonstrate the operation, theory, repair and servicing of Blood Pressure equipment that used at clinics & hospitals. The unit is given the fault diagnosis so as to facilitate the teaching of trouble shooting techniques. A fault simulator is provided with circuit block diagram of the device for the students to study theoretically and experimentally in order to understand the operation of the device.
