Treatment equipment for medical cryoplasty

Abstract

The invention discloses treatment equipment for medical cryoplasty. The treatment equipment comprises a refrigeration device for providing a cold source, a liquid storage tank, a conveying pump and aheat exchanger, wherein the liquid storage tank is used for storing a liquid treatment working medium with a freezing point lower than a threshold value; the conveying pump is used for pumping the working medium in the liquid storage tank to a treatment working medium cycle; the heat exchanger is used for carrying out heat exchange to replace the cooling capacity of a cold source to the treatmentworking medium, so as to provide the treatment working medium cooled to treatment temprature to the cryoplasty, wherein the treatment working medium flowing out from the cryoplasty in the treatment working medium cycle can reflow back to the liquid storage tank. Compared with the prior art, the treatment equipment provided by the scheme provides the heat exchange cooling capacity to the liquid treatment working medium through a refrigeration cold source and a formation mechanism of the treatment cooling capacity is changed, so that the surgical safety and economical performance can be comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a treatment device for a medical freezing balloon. Background technique [0002] Atrial fibrillation (atrial fibrillation, AF) is a common arrhythmia, clinically manifested as an atrial rhythm with disordered excitation and ineffective contraction of the atrium, and many small reentrant circuits caused by the atrial-dominant reentrant circuit. Arrhythmia caused. The disease has a high incidence and long duration, and it can also cause serious complications, such as heart failure and arterial embolism, resulting in disability or increased mortality of patients. During the course of the disease, the regular and orderly atrial electrical activity is lost, replaced by rapid and disorderly fibrillation waves, and the disordered atrial fibrillation loses effective contraction and relaxation, resulting in deterioration or loss of atrial pumping function, resulting in extreme ve...

AI Technical Summary

Problems solved by technology

The balloon needs to be folded and put into the balloon catheter. Due to this limitation, the wall of the balloon made of polymer film needs to be as thin as possible, and the mechanical strength is relatively low, which poses a great safety hazard in the application scenario of high-pressure gas

In addition, the nitrous oxide working fluid used in the operation has a certain poisonous effect. The gas working fluid discharged during the operation needs to be connected to the discharge system through a special discharge pipe. After each gas consumption, the gas cylinder needs to be replaced. The work is relatively cumbersome and the price is relatively high. Expensive, the cost of treatment cannot be effectively controlled as a whole
