Problems solved by technology

[0002] The current anti-reflux infusion set does not have an exhaust device. When it is in use, it needs to manually discharge the excess air in the anti-reflux dropper or Murphy's tube, and generally it takes more than 20 seconds to complete the extrusion and exhaust, which is significantly reduced. work efficiency

Abstract

Disclosed in embodiments of the present invention is an air-exhaust device for backflow-preventing blood transfusion apparatus, said device comprising a base, an air-filtering membrane and a hermetic stopper, one end of the base being communicated with a hollow tube protruding from one side wall of the backflow-preventing blood transfusion apparatus, the other end being connected to the openable and closable hermetic stopper, and the air-filtering membrane being fixed inside the base. The simple structure and low cost of the present embodiments simplify air exhaust operations.

Description

technical field [0001] The patent of the present invention relates to the exhaust device of the disposable infusion set, especially to the exhaust device of the disposable anti-return blood infusion set. Background technique [0002] The current anti-return infusion set does not have an exhaust device. During use, it is necessary to manually discharge the excess air in the anti-return dropper or Murphy's tube, and generally it takes more than 20 seconds to complete the extrusion and exhaust, which is significantly reduced. work efficiency. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an exhaust device for an anti-return blood infusion set, which simplifies the exhaust operation and shortens the exhaust time of the anti-return blood infusion set. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: an exhaust device for an anti-return bl...
