Drainage device for cardiovascular surgery

Abstract

The invention relates to the technical field of drainage devices, and discloses a drainage device for cardiovascular surgery. The drainage device includes a pedestal; the top surface of the pedestal is fixedly connected to a negative pressure box and a fixing table; the top surface of the fixing table is movably sleeved by a movable sleeve; the side of the movable sleeve is sleeved by a support plate; the top surface of the support plate is fixedly connected to fixing sleeves; and storage bottles are movably sleeved by the fixing sleeves. Through the fixed connection of the fixing table on thetop surface of the pedestal and the movable clamping connection of the movable sleeve on the outer surface of the fixing table, the movable sleeve can rotate on the outer surface of the fixing table,and the outer surface of the movable sleeve is movably sleeved by the support plate; the multiple sets of the storage bottles can be stably placed by using the fixing sleeves on the support plate, sothat a suction catheter can be directly changed and communicates with a new storage bottle after the storage of one bottle is accomplished, therefore, the change speed of the storage bottles can be accelerated, the pain level of patients can be decreased, and use convenience can be enhanced.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a drainage device for cardiovascular surgery. Background technique [0002] The heart is a hollow muscular organ located in the middle of the chest cavity, divided into two chambers by a septum, and each chamber is divided into two parts: the upper atrium and the lower ventricle. The atrium collects blood from the heart, and the ventricle ejects blood from the heart. There are valves at the inlet and outlet of the ventricle to ensure the one-way flow of blood. Under different physiological conditions of the human body, the metabolic levels of various organs and tissues are different, and the requirements for blood flow are also different. Cardiovascular activity can change the cardiac output and peripheral resistance under the mediation of the body's nerves and body fluids, and coordinate the distribution of blood flow among various organs and tissues to meet the needs ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a drainage device for cardiovascular surgery, which has the advantages of convenient replacement of the storage bottle and stable extraction of the suction catheter, and solves the problem that the existing replacement operation mentioned in the above-mentioned background technology is relatively complicated. , it is necessary to unfix the storage bottle, fix a new storage bottle, and install a suction catheter, which makes the actual suction speed slower and increases the time for the patient to suffer pain, and the increase in operation time has an increase in the probability of additional risks , the problem of poor security effect
