Low-temperature therapeutic equipment using coolant

Abstract

The invention discloses low-temperature therapeutic equipment using a coolant. The therapeutic equipment comprises a refrigerating device, a one-way valve, a coolant storage tank, a coolant recovery tank, an air compressor, an air storage tank, an adjusting valve, a control system, a low-temperature probe and the like, wherein the air compressor compresses air into certain high pressure and stores the compressed air in the air storage tank; when the coolant, namely low-temperature silicone oil, refrigerated by the refrigerating device flows into the storage tank through the one-way valve and is accumulated to a certain amount, a liquid level sensor transmits a signal to a programmable controller to open the adjusting valve so as to charge the compressed air into the storage tank; the programmable controller controls the opening of the adjusting valve through a pressure signal detected by a pressure sensor, so that the low-temperature silicone oil is squeezed out of the storage tank bya corrugated pipe at a certain flow rate to flow to the low-temperature probe, and the silicon oil flowing out from the low-temperature probe returns to the recovery tank. The equipment can be applied to cold therapy on diseased tissues.

Description

technical field [0001] The invention relates to a low-temperature treatment device using a brine. Background technique [0002] Cryosurgery is a clinical medicine in which cryogenic instruments are used as surgical treatment tools. It can be used to remove lesions or repair physical defects to restore and improve body functions. Cryosurgery is primarily used for the excision of tumors, sometimes called cryogenic tumor resection, and has been used in many branches of surgery. Hypothermic surgery can replace other surgical resections without sutures, and has the advantages of anesthesia and analgesia, sterility, hemostasis and reduced bleeding, mild reaction, high safety, no side effects, short recovery time, and the ability to prevent tumor spread. Therefore, until now, cryosurgery has been considered an important method for the treatment of highly drug-resistant bulky tumors. [0003] According to the characteristics and location of the lesion tissue, different cryogenic i...

AI Technical Summary

Problems solved by technology

Liquid nitrogen is a low-temperature medium widely used at present, but using liquid nitrogen as a cold source also has its disadvantages: when liquid nitrogen reaches the probe tip and undergoes a phase change, a large amount of gas will be generated, and the pressure generated will slow down the liquid nitrogen. Flow rate; the cooling speed of the probe is slow, and the pre-cooling time is long; liquid nitrogen freezing equipment involves the storage, output, and recovery of liquid nitrogen, which is difficult to be widely used in some remote areas
