It works as follows:
The urine bag set consists of A drainage bag and A suction device. Qhy-a is the single drainage bag, and qhy-b is the drainage bag + suction device. The drainage bag consists of the bag body, Catheter , lifting lug, joint, guard cap, drainage port, drainage bottom plug, anti-reflux device, and current limiting clip.The suction device is composed of negative pressure bottle, drainage tube joint, suction tube joint, suction connection pipe, automatic drainage device, drainage port and bag body.Should be sterile.
It is used for the collection of body fluids (blood, gastric juice, etc.), secretions (sputum, flushing fluid, etc.) and human excreta (urine, etc.) in hospital, clinical departments and during surgery or after surgery.

First, the opening process 1 In the closed position, the ball is pressed by the [wiki] mechanical [/wiki] of the valve stem, pressed against the valve seat.
2 When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and the bottom angular plane causes the ball to disengage from the valve seat.
3 The valve stem continues to lift and interacts with the guide pin in the screw groove of the valve stem, causing the ball to start rotating without friction.
4 Until the fully open position, the stem is raised to the extreme position and the ball is rotated to the fully open position.
Second, the closing process 1 When closing, turn the handwheel clockwise, the valve stem begins to descend and the ball leaves the valve seat to start rotating.
2 Continue to rotate the hand wheel. The valve stem is subjected to the guide pin embedded in the upper spiral groove, so that the valve stem and the ball rotate at 90° at the same time.
3 When it is about to close, the ball has rotated 90° without contact with the seat.
After a few turns of the zui of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges against the ball, so that it is pressed tightly against the valve seat to achieve a complete seal.
