[0029] Working principle: when using the device, first insert the connector 1 into the urinary catheter on the patient's body for use;
[0030] First innovative point implementation steps:
[0031] First step: by inserting the plug 18 at one end of the cannula 10 into the piston 11, then rotating the valve disc 15 to make the three-way valve 14 control the second tube 3 to close, and the first tube 2 and the third tube 13 to open, then the flushing liquid in the flushing liquid bottle 6 enters the cannula 10 through the washing liquid tube 8, then flows out through the liquid outlet 17 on the plug 18 into the injection tube 12, then the flushing liquid enters the three-way valve 14 through the third tube 13, then enters the connector 1 through the first tube 2, and then enters the urinary catheter through the connector 1, and then enters the patient's bladder for flushing. The flushing liquid in the flushing liquid bottle 6 directly and continuously enters the injection tube 12 through the washing liquid tube 8. Compared with the multiple pumping of the piston 11 in the injection tube 12, the repeated flushing is reduced, thereby avoiding joint infection;
[0032] Second step: adjust the flow rate by the flow clamp 7. When pumping the bladder liquid, pull the pull plate 9 outward to pull the piston 11 and the cannula 10 outward at the same time. The barb 19 plays a role in fixing the cannula 10 from falling off the piston 11. At the same time, rotate the valve disc 15 to make the second tube 3 open, and the flow clamp 7 close the liquid flow in the washing liquid tube 8. By pulling the pull plate 9 outward, the bladder liquid and blockage enter the first tube 2 through the connector 1, then enter the drainage tube 4 through the second tube 3, and then enter the drainage bag 5 for collection, ensuring that the injection tube 12 and the third tube 13 are in a sterile state;
[0033] Third step: by adjusting the clamping block 22 in the different position of the lug 21 between the recess of the clamp head 20, the degree of extrusion of the washing liquid pipe 8 is different, the control of the flow of the washing liquid pipe 8 is adjusted, when the clamp head 20 is clamped in the innermost recess, the extrusion of the washing liquid pipe 8 between the clamping block 22 is closed, the flow of the washing liquid pipe 8 is closed.
[0034] Second innovative point implementation steps:
[0035] The connecting head 1 is trapezoidal, gradually thickens from one end, and cooperates with multiple convex rings 16, so that the connecting head 1 is convenient for connecting urinary catheters of various sizes and diameters, and has strong applicability.
