A voltage regulator maintains a constant voltage level. Two common DC voltage regulators are linear regulators and switching regulators. Linear regulators continuously adjust to changes at the input to maintain a constant ...
A transformer is a device that changes electrical energy from one voltage to another voltage. Step up transformers increase the voltage. Step down transformers decrease the voltage. Wall transformers can also change ...
Proper grounding is very important. The ground connection increases safety for the patient, technician, and device. The instruments are powered through wall power terminals. Wall power terminals have provisions for providing ...
Friction between the copper segments of the commutator and the brushes eventually wears both surfaces. Older copper brushes can cause more wear to the commutator. The commutator surface may have deep grooves and notches ...

A bent shaft increases motor vibration. A bent shaft can be responsible for the noisy operation of a motor. A bent shaft in motor should be corrected or replaced for proper operation of a motor.
The Biomedical Technician’s Assessment Instrument Package includes the foundations of survey instruments, survey scripts, and reference materials used in the assessment of biomedical technician’s impact on hospitals in ...
The primary function of blood is to supply nutrients and constitutional elements to tissues and to remove waste products. Blood also enables cells and different substances to be transported between tissues and organs. ...
Bottled oxygen is supplied under pressure in specially designed steel cylinders of varying sizes. British Standard oxygen bottles range in capacity from 170 litres to 6800 litres.
An electric brush is part of a motor. DC motors have several spring-loaded brushes pushing against each side of the motor’s commutator. Electric brushes conduct electricity between the motor’s fixed wiring (stator) and the ...
Rechargeable batteries are common in medical equipment. Batteries convert chemical energy into electrical energy. This process can be reversed in rechargeable batteries, converting electrical energy into chemical energy.
Once ...
This skill is an introduction to basic circuit theory. First, you must understand that electricity only flows in a closed circuit. A closed circuit is a loop of materials that will conduct electricity. An open circuit is ...
Cable strain relief systems are important to protect the cable fiber at the plug or the connector. Cable strain relief systems are conical polymers that allow the fiber within the cable to bend, minimizing the stress where ...
A blood pressure (BP) apparatus or sphygmomanometer is a medical device. A BP apparatus measures the vital sign of blood pressure. A BP apparatus has two parts: an inflatable cuff and a manometer. The inflatable cuff ...
Calibration compares an instrument’s output against an accurate standard. Once an error is known, any deviations can be corrected. For example, a thermometer could be calibrated and adjusted to show the true temperature ...
A non-invasive blood pressure machine is a medical device used to measure blood pressure. A non-invasive blood pressure machine is electric. A non-invasive blood pressure machine consists of an inflatable cuff and an ...
