Introduction of Pulsed Shortwave Diathermy Therapy System Physiotherapy Equipment

The pulsed short-wave diathermy therapy system uses electron tube oscillation to generate short waves with a working frequency of 27.12MHz and outputs energy through capacitor electrodes. The lesion part is placed between two square electrode plates. Under the action of a radio frequency electric field, the molecules and ions in the lesion vibrate in a parallel position and rubs against each other to produce a thermal effect. This thermal effect will heat the surface and deep tissues of the affected area evenly, which can enhance vascular permeability, improve micro-circulation, regulate endocrine, strengthen the metabolism of the tissue body, and reduce the excitability of sensory nerves, so as to relieve the pain.

Clinical Mechanism of Shortwave Diathermy Physiotherapy Equipment

Electromagnetic waves with a frequency of 27.12MHz are used in clinical treatment. There are three main effects of shortwave acting on the human body: thermal effect, micro-thermal effect, and non-thermal effect.

1. Thermal effect

The internal heat generated after the tissue absorbs electric energy, which can reach the deep part of the body, with uniformity and selectivity. This feature has a unique therapeutic effect on nerves, bones, and internal organs.

2. Micro-heat effect

It can improve blood circulation, has the effects of analgesia, anti-inflammatory, and lower muscle tension.

3. No heat effect

It has a unique clinical effect on anti-inflammatory, accelerating tissue growth and repair, and improving immunity under sub-acute conditions.
