Pericardium-to-femoral vein drainage assembly

Abstract

The invention relates to the technical field of medical treatment, in particular to a pericardium-to-femoral vein drainage assembly. The supporting plate is fixed on the inner side of the drainage box; a positioning groove is formed in one side of the supporting plate, the blood storage box is detachably arranged on the inner side of the positioning groove, and an anti-falling fixing device is arranged on one side of the blood storage box; the sealing ring can slide on the inner side of the blood storage box, a sliding plate is fixedly arranged on the inner side of the sealing ring, a long blood supply hose is arranged on one side of the sliding plate, and a first flow limiting connecting device is arranged between the long blood supply hose and the sliding plate. By arranging the drainage box, the supporting plate, the blood storage box, the sealing ring, the sliding plate, the long blood supply hose, the long blood drawing hose, the needle head, the sliding block, the control panel, the processing controller, the pressing frame and the J-shaped locking buckle, the device has the functions of automatic intermittent drainage, accurate drainage, convenience in disassembly, convenience in cleaning and disinfection, one-way drainage, backflow prevention, automatic cutoff, safety protection and the like.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a drainage assembly from the pericardium to the femoral vein. Background technique [0002] The pericardium is the membranous sac that covers the surface of the heart. The pericardium is divided into a fibrous layer and a serosal layer. The fibrous layer is relatively tough and closely adheres to the wall layer of the serosal layer, with little flexibility. The serosal layer is very thin, smooth and moist, and is divided into a parietal layer and a visceral layer. The parietal layer is attached to the inner surface of the fibrous layer, and the visceral layer is attached to the surface of the heart (ie, the epicardium). There is a cavity between the visceral and wall layers, called the pericardial cavity. The pericardium has a protective effect on the heart and can prevent excessive expansion of the cardiac chambers to maintain a constant blood volume. [0003] The femoral ve...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that when the blood drainage assembly in the prior art drains the blood, it can only flow to the femoral vein by the pressure of the blood itself, and cannot accurately control the blood supply speed, and when the doctor performs the operation, It may squeeze the patient's leg and increase the blood pressure of the femoral vein. At this time, blood backflow may occur, causing the patient's pericardial blood pressure to increase and causing damage to the patient's heart. , it is not easy to disassemble, so it is not easy to clean and disinfect, and a kind of pericardium to femoral vein drainage assembly is proposed
