Skin cooling device for laser therapy

Abstract

The invention relates to a skin cooling device for laser therapy. The skin cooling device comprises a coolant storage tank, a hose, an electromagnetic valve, a nozzle, an infrared temperature sensor, an electromagnetic valve driving circuit and a central control device, wherein the coolant storage tank is connected with the nozzle through the hose; the electromagnetic valve is arranged on a passage between the nozzle and the hose; the infrared temperature sensor is used for monitoring temperature of an affected face; the electromagnetic valve driving circuit is used for driving the electromagnetic valve to work; the infrared temperature sensor is in circuit connection with the central control device; and the central control device is in circuit connection with the electromagnetic valve driving circuit and a laser therapeutic apparatus. The skin cooling device has the beneficial effects that 1, a temperature monitor is arranged, so that whether an atomized coolant is sprayed can be monitored, the spray amount of the coolant is monitored, and the phenomenon of tissue burn caused by insufficient coolant spray is avoided, 2, the coolant is firstly pre-sprayed once for judging whether the work is normal and then the coolant is sprayed formally in order to solve the problem of time delay of heat transfer, and 3, a safety valve is used for cutting off a cooling pipeline when accidental leakage of the pipeline occurs so as to prevent continuous leakage.

Description

technical field [0001] The present invention relates to a medical device, in particular to a skin cooling device for laser therapy. Background technique [0002] The laser treatment instrument uses selective photothermal action to irradiate various skin lesions, and uses different wavelengths or treatment methods to achieve the treatment of various diseases. Although each tissue has selective heat absorption for different wavelengths of laser light, it is still difficult to avoid thermal damage to irrelevant tissues around the lesion. [0003] In the prior art, the method of spraying coolant to cool the skin surface has a good cooling effect without touching the affected surface, but if the coolant is accidentally sprayed abnormally during the process of spraying the coolant, the skin will not be cooled enough, which will affect the curative effect , or even cause damage to the patient. Contents of the invention [0004] The present invention aims to solve the above prob...
