A sterile docking valve

Abstract

The invention discloses an aseptic butt joint valve, which includes a first valve, a second valve and a cover opening mechanism. The first valve has a fixed valve body and a first movable valve cover, and the second valve has a movable valve body and a second movable valve cover. . The cover-opening mechanism is used to drive the first movable bonnet to perform overturning movement when the first movable bonnet cooperates with the second movable bonnet, so as to open or close the second movable bonnet; the cover-opening mechanism includes a driving component and a driven component Driven transition piece, the end of the transition piece facing away from the drive assembly is connected to the first movable bonnet, the drive assembly drives the transition piece to rotate to drive the first movable bonnet to perform a flipping movement, through the forward or reverse flipping movement, to achieve the second Automatic opening or closing of movable bonnet. The turning point of the transition piece acts as a fulcrum, and the driving assembly and the first movable valve cover are respectively located on both sides of the turning point of the transition piece, forming a lever principle and reducing the force required for the rotation of the first movable valve cover; the transition piece also serves as a counterweight , to balance the counterweights on both sides of the fulcrum.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to an aseptic butt joint valve. Background technique [0002] With the continuous development of medical technology and biotechnology and other fields, there is a demand for aseptic transmission of biological tissues or organs in vitro and packaging in a clean environment. Devices and equipment are required to provide for the aseptic transmission and packaging in a clean environment Full-chain closed technical support, and requires this technical support to be a solution for intelligent automation and full traceability of information. For example, in order to treat the cause of the disease during surgery, it is necessary to store the organs in a clean environment outside the body for a period of time before replanting or transplanting, or after the organs are cultured in vitro in the laboratory of genetic engineering, they enter the operating room for transplantation, etc...
