Category: Therapeutic Instrumentation

We have different types of therapeutic instruments. Some of these instruments and equipment include: cardiac pacemakers, ventilators, radiotherapy instruments, cardiac defibrillators, haemodialysis machines, lithotriptors, laser equipment, etc.

What is Intraoperative Radiotherapy?

Intraoperative radiotherapy (IORT) is a method that combines radiation therapy with surgery to irradiate tumours in situ, without delivering a significant dose to surrounding normal, critical structures and is typically performed using electron beams from linear accelerators. This contrasts with … Read More

The Functions of Humidifiers, Nebulizers and Aspirators as Respiratory Therapeutic Instruments

Humidifiers

Humidifiers are used to increase the humidity (water content) of the inspired air. The humidity of the inhaled air should be high (near 100%) in order to avoid damage to the upper air passage of the lungs. Hence, the … Read More

Application of Diathermy as a Therapeutic Treatment

Diathermy is the process through which electrically induced heat or the application of high frequency electromagnetic currents as a form of physical therapy and in surgical procedures.

Diathermy is commonly used for muscle relaxation. It is possible to pass high … Read More

The Laser Technology and How it is applied in Medical Field

The word laser is an acronym that stands for light amplification by stimulated emission of radiation. A laser is defined as a beam of monochromatic light that carries with it a high energy. The monochromatic light can be focused on … Read More

How a Ventilator is used to Deliver Oxygen to a Patient with a Breathing difficulty

A ventilator is used on patients who go into respiratory failure and cannot maintain breathing for some reasons. Respiratory failure occurs when the body’s metabolic needs are not met. If this is not corrected, then the patient will have laboured … Read More

Cardiac Defibrillators

Ventricular fibrillation is a serious cardiac emergency resulting from asynchronous contraction of the heart muscles. This uncoordinated movement of the ventricle walls of the heart may result from coronary occlusion, from electric shock or from abnormalities of body chemistry. Due … Read More
