Drain valve of drainage bag

Abstract

The invention discloses a drain valve of a drainage bag. The drain valve comprises a valve casing and a drain hole below. The drain valve is characterized in that a liquid inlet leading to the interior of the valve casing is arranged in the side wall of the valve casing; and a switch touch part is connected with a lower closing part by a transmission mechanism. The drain valve is convenient to operate, thus preventing the operators and users from being subject to cross infection due to improper operation of the drain valve.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a drain valve for a drainage bag. Background technique [0002] The drain valves of existing drainage bags mainly include cross valves, pull valves, screw valves, flip valves, hose clips (including Robert clips, sheet clips, roller flow regulators, flip clips), etc., but they have a common The characteristic is that the drain valve and the drain port are generally located at the bottom of the bag body, and the switch touch part is close to the drain port, and the drainage bag sometimes needs to be used continuously for several days, and it needs to be opened and closed several times a day to discharge the drainage fluid. When the drainage valve is closed at the end of the liquid, since the touch part of the switch is close to the liquid discharge port, the operation is frequent, and the drainage liquid on the liquid discharge port is likely to get on the hands of the operator. Espe...
