Outlet connecting mechanism of artificial blood pump and assembling method of outlet connecting mechanism

Abstract

The invention provides an outlet connecting mechanism of an artificial blood pump. The outlet connecting mechanism comprises a first part and a second part, wherein the first part comprises the artificial blood pump and a blood pump outlet adapter connected with the artificial blood pump, the second part comprises an artificial blood vessel, an artificial blood vessel sleeve connected with the artificial blood vessel and a locking ring, and the locking ring is arranged on the artificial blood vessel sleeve, is axially fixed to the artificial blood vessel sleeve, is movably connected with the artificial blood vessel sleeve in the circumferential direction and is connected with the blood pump outlet adapter through threads. The invention further provides an assembling method of the outlet connecting mechanism of the artificial blood pump. The outlet connecting mechanism of the artificial blood pump and the assembling method of the outlet connecting mechanism have the beneficial effects that the use of bolts is avoided, the operation is relatively convenient, the difficulty of operation is relatively low, and the connecting structure is simple and reliable.

Description

Technical field [0001] The invention relates to medical equipment, in particular to an outlet connecting mechanism of an artificial blood pump and an assembly method thereof. Background technique [0002] The artificial blood pump is a device connected between the ventricle and the blood vessels to assist patients with severe ventricular insufficiency or heart failure to provide a certain blood flow and blood pressure. The outlet of the artificial blood pump is connected to the main blood vessel of the human body through an artificial blood vessel. There are high requirements for the way the blood pump is connected to the artificial blood vessel: not only the sealing of the connection must be ensured, but also the smoothness and smoothness of the blood channel to avoid Problems such as hemolysis and thrombosis. In addition, the pressure at the outlet of the blood pump is relatively high, and the connection mechanism needs to meet the pressure requirement. [0003] At the same tim...

AI Technical Summary

Problems solved by technology

This connection mechanism needs to process suitable bolts, and the bolts are very small. During the operation, the bolts must be inserted into the holes of the snap ring, and then the bolts are tightened, which is not very convenient to operate; During the operation, it may fall into the chest cavity due to the operator's mistake, increasing the difficulty of the operation
