Optical physiotherapy instrument

Abstract

The invention provides an optical physiotherapy instrument which is equipped with a liquid filtering mirror that is small in size and high in sealing strength. The physiotherapy instrument is that a wide-spectrum light source is used as a lighting body; a special reflecting cup is used for filtering the generated light through the novel liquid filtering mirror, and therefore, the light which easily leads to heat effect to the skin can be greatly filtered, and the high-energy light wave which is accepted by the patient and has high treatment value can be remained, and a visible light wave section and some near infrared light wave section are covered.

Description

technical field [0001] The invention relates to a phototherapy instrument used in the medical field, in particular to an optical physiotherapy instrument for phototherapy covering an ultra-wide spectrum of visible light and infrared light. Background technique [0002] Light therapy is a treatment method that uses artificial light sources or natural light sources to prevent and treat diseases and promote body recovery. Light therapy mainly includes ultraviolet therapy, visible light therapy, infrared therapy and laser therapy, and is a common method of physical factor therapy. Light therapy uses itself to transform the energy carried by itself into the biological energy that is sensitive and usable by different tissues of our human body when it penetrates the human body, so as to achieve the therapeutic effect on related diseases. Its three major therapeutic areas are tissue repair, wound healing, immune Regulation, chronic inflammation, allergic inflammation, pain relief. ...

AI Technical Summary

Problems solved by technology

However, most broad-spectrum light sources cover more near-infrared spectrum, which can easily cause skin thermal burns, so the energy of the entire light source cannot be improved.

[0005] In order to solve the above problems, the prior art instruments often use a liquid filter to selectively filter the light source to filter out unnecessary and harmful wave bands of the light source, but the volume of the liquid filter in the prior art is too large, A large cooling system is required to cool the liquid in the filter; the sealing is poor, and when the temperature changes greatly, because the expansion coefficient of the liquid is greater than the expansion coefficient of the metal, a large pressure is generated inside the filter, and the liquid is easy to leak; when the liquid When absorbing too much heat, due to the increase of liquid expansion pressure, there may be an explosion situation
