Abstract

The invention discloses a medical manual automatic control secondary filter valve belonging to the technical field of medical appliances. The medical manual automatic control secondary filter valve comprises a valve body, a fixing ring, a valve core, a spring, a regulating screw, a bolt, a rubber gasket, a rubber cushion, a filter film and a valve nozzle. The pressure difference of the valve is regulated by rotating the regulating screw, a secondary filter film filters media, and the outlet end of the valve is an outer cone joint of 6:100. When the medical manual automatic control secondary filter valve is used, the pressure difference of the valve can be arbitrarily regulated; when the pressure difference of both ends of the valve exceeds a predetermined value, the valve core is automatically opened; and when the valve core is deadlocked or needed, the valve core can be manually opened by pressing a cylinder arranged at the upper end of the valve core. When air pressure exists, a connection injection needle can distinguish and inflate vacuum medicines to prevent the medicines and a whole transfusion system from being polluted by bacteria, viruses, and dust particulates and prevent infusion reaction.

Description

Technical field: [0001] The invention discloses a medical manual and automatic control precision filter valve, which belongs to the technical field of medical equipment. Background technique: [0002] The existing valve can only be controlled manually or automatically without precision filtering function, and cannot be connected with the 6:100 inner conical joint. Invention content: [0003] The purpose of the present invention is to disclose a valve core that is automatically opened when the pressure difference at both ends of the valve core exceeds a preset value during use, and the valve core can also be manually opened when it is stuck or needed; The precision filter membrane is replaceable; the outlet end of the valve is a 6:100 external conical joint. The technical structure of the valve guarantees manual or automatic control, can filter the passing medium precisely, and can be connected with a 6:100 inner conical joint. When there is air pressure, the connected in...
