Integrated ureteral stent tube

Abstract

The invention provides an integrated ureteral stent tube, which specifically comprises a drainage mechanism; a back-suction mechanism is mounted above the drainage mechanism; a positioning mechanism is mounted above the drainage mechanism at the far end; a communicating mechanism is mounted above the positioning mechanism; a supporting mechanism is mounted in the positioning mechanism; and a bent pipe is mounted below the drainage mechanism at the near end. According to the invention, the angle of a directional opening of a back-suction tube can ensure that urine on the outer side of the device enters a drainage tube when flowing downwards; urine in the drainage tube does not enter the outside of the drainage tube; therefore, urine intercepted in a ureter after contact sealing between the drainage mechanism and the special position of the ureter can be effectively reduced; ureteral infection is prevented; and, by means of the structure, the following problems are solved: after an existing ureteral stent is inserted into the ureter, position contact sealing exists between the stent and the inner wall of the ureter; urine is easily intercepted; and the ureteral infection is easily caused.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to an integrated ureteral stent tube. Background technique [0002] The ureteral stent is a specially designed hollow tubular stent placed on the lumen of the patient's ureter. It is one of the commonly used instruments in urology. Obstruction and stenosis. [0003] Based on the findings of the prior art, when the existing ureteral stent is in use, after the stent is inserted into the ureter, due to the curved structure between the renal pelvis, ureter, and bladder, the stent will contact and seal with the inner wall of the ureter, which will easily lead to a gap between the stent and the ureter. The urine in the space is trapped and stored, which can easily cause ureteral infection and aggravate the pain of the patient; at the same time, when the existing ureteral stent is used, the double J tube structure is used, and the curved tubes on both sides increas...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides an integrated ureteral stent tube to solve the problem that after the existing ureteral stent is inserted into the ureter, due to the curved structure of the ureter, the stent will contact and seal with the inner wall of the ureter, which will easily cause urine to be trapped. The entrapment can easily cause ureteral infection; at the same time, the double J tube structure used in the existing ureteral stent, the elbow at the far end will cause scratches and impacts on the inner wall of the renal pelvis when the patient moves, making the patient feel uncomfortable
