Negative pressure drainage device for cardiovascular medicine department

Abstract

The invention discloses a cardiovascular medicine department negative pressure drainage device which comprises a base, a supporting rod fixedly connected to the upper end of the base and an air pressure component, the base is used for supporting parts of the negative pressure drainage device, and the air pressure component comprises a sealing cavity, an air inlet pipe and an air conveying pipe. The lower end of the sealing cavity is connected to the upper end of the supporting rod in a sleeving mode, one end of the air inlet pipe is fixedly communicated with the interior of the sealing cavity, the two air conveying pipes penetrate through the upper side wall of the sealing cavity, and one-way valves are arranged on the air inlet pipe and the air conveying pipes correspondingly. Gas in the gas storage cylinder can enter the drainage device through the through holes in the circular plate and the sealing plate and the guide pipe to relieve the situation that the negative pressure in the drainage device is too large, and when the negative pressure in the drainage device reaches a reasonable range, the negative pressure in the drainage device can be automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of cardiovascular internal medicine devices, in particular to a negative pressure drainage device for cardiovascular internal medicine. Background technique [0002] Cardiovascular disease is a group of diseases involving the heart or blood vessels, including coronary heart disease such as angina pectoris and myocardial infarction, others including stroke, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, abnormal heart rhythm, congenital heart disease, etc. , in the treatment of cardiovascular diseases, there will be effusion in the patient's body, so it is necessary to drain the effusion. [0003] However, the existing negative pressure drainage device for cardiovascular internal medicine cannot adjust the negative pressure drainage device according to the required working height. At the same time, because the negative pressure drainage device does not have a structure for...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. The existing negative pressure drainage device for cardiovascular medicine cannot adjust the negative pressure drainage device according to the required working height. At the same time, because the negative pressure drainage device does not have automatic Adjust the structure of the negative pressure value inside the device, so when the negative pressure value is large in use, it is easy to cause internal discomfort in the patient's body, and a negative pressure drainage device for cardiovascular medicine is proposed
