A naturally aspirated cryoablation system

Abstract

The naturally aspirated cryoablation system disclosed in the invention belongs to the technical field of medical equipment, and includes a gas supply station and a main engine. The gas supply station includes a first gas compression unit, a second gas compression unit, a gas supply station drive unit, a discharge unit and The gas storage unit; the host includes a gas distribution unit, a gas pre-cooling pool, a working gas output interface and a host drive control unit. The naturally aspirated cryoablation system of the present invention does not require special refrigerant gas as the energy source for refrigeration. It adopts the method of natural suction, compresses the air through electric energy, and then generates cold energy through the throttling characteristics of high-pressure air, thereby promoting The popularization and use of cryoablation equipment has effectively reduced the accumulation of patients in large cities, enabling patients to receive timely treatment nearby, reducing the fatigue of patients on their journeys, and saving treatment costs.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a naturally aspirated cryoablation system. Background technique [0002] With the continuous development of freezing technology, it has been used more and more in clinical practice, and the advantages of freezing technology in disease treatment have been recognized by a wide range of experts, and the scope of application and diseases are becoming wider and wider. For example, the "argon-helium knife" used for tumor treatment, which uses argon as the refrigerant gas for refrigeration and helium as the heat medium gas for heating, has been widely recognized in the field of tumor treatment; the freezing system for bronchoscopic biopsy , which uses carbon dioxide gas as a refrigerant, combined with the characteristics of freezing to have adhesion, and extracts lung tissue through a bronchoscope; the cryogenic system that has been developed to treat atrial fibrillation curre...

AI Technical Summary

Problems solved by technology

However, my country's gas resources are limited. For first-tier cities, gas supply is acceptable, but for remote second-tier and third-tier cities, gas supply is affected by many unfavorable conditions such as transportation, mountains, environment, and manufacturers, making it difficult to supply. , making it difficult for this kind of refrigeration equipment to be applied in second-tier and third-tier cities, which will lead to the accumulation of patients in large cities, so the supply of refrigerant gas has become a "stuck neck" problem in the development of refrigeration equipment applications
