Embodiment 1

[0026] refer to Figure 1-5 In this embodiment, a multifunctional anti-clogging and anti-urethral injury bladder flushing catheter is proposed, including a fixed cover 1, a connecting pipe 4 is threadedly connected to the inner wall of the bottom of the fixed cover 1, and the connecting pipe 4 is rotatably connected with a limit rod 5. The limit rod 5 is slidingly connected to the inner wall of the fixed cover 1, and the inner tube 6 is slidably connected to the inner wall of the connecting pipe 4. The bottom end of the inner tube 6 extends to the bottom of the connecting pipe 4 and is fixedly installed with a joint 7. The fixed cover Mounting holes 21 are provided on both sides of the inner wall of 1, and a silica gel pad 22 is sealed and fixed in the mounting holes 21. On both sides of the inner wall of the fixed cover 1, a retaining ball 20 is rotatably connected, and the two retaining balls 20 are respectively connected with the The two silica gel pads 22 are in movable co...

Embodiment 2

[0029] In this embodiment, a nut 2 is fixedly installed on the bottom of the fixed cover 1, and a threaded pipe 3 is fixedly set on the connecting pipe 4. The threaded pipe 3 runs through the nut 2 and is threadedly connected with the nut 2. The threaded pipe 3 can be used to facilitate the connection. The pipe 4 moves, and the position of the connecting pipe 4 can be conveniently limited.

[0030] In this embodiment, a drain pipe 8 is fixedly installed at the bottom of one side of the fixed cover 1, and the drain pipe 8 communicates with the fixed cover 1, and a sealing plug 9 is installed in the seal of the drain pipe 8, so as to facilitate the Urine comes out.

[0031] In this embodiment, the top of the inner pipe 6 is fixedly covered with a flow box 14, the top of the flow box 14 extends to the top of the connecting pipe 4 and is fixedly connected with the bottom of the cover plate 15, and the inner walls of both sides of the flow box 14 are embedded with The water net 25...

Abstract

The invention belongs to the field of medical instruments, particularly relates to a multifunctional anti-blocking urethral injury prevention bladder irrigation catheter, and aims to solve the problems that in the prior art, an irrigation catheter needs to be repeatedly inserted into the body of a patient, and the catheter needs to be repeatedly pulled and inserted, so that the pain of the patientis increased, and a certain trouble is brought to medical staff. According to the following scheme, the multifunctional anti-blocking urethral injury prevention bladder irrigation catheter comprisesa connecting pipe which is connected to the inner wall of the bottom of a fixing cover in a threaded mode, wherein a limiting rod is rotationally connected to the connecting pipe, and the limiting rod is slidably connected with the inner wall of the fixing cover; therefore, two blocking balls do arc-shaped movement by rotating the connecting pipe, and silica gel pads are tightly attached to the inner wall of a bladder and a fixing effect is achieved; in addition, cleaning fluid can be injected into the bladder through an inner tube, so that the bladder can be conveniently cleaned, the urethral catheter and a flushing tube do not need to be frequently replaced during use, pain of the patient can be greatly relieved, and meanwhile the urethral catheter can be conveniently used by medical staff.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional anti-blockage and anti-urethral injury bladder irrigation catheter. Background technique [0002] As we all know, due to the existence of natural orifices in the human body such as the urethra and ureter, the amount of minimally invasive surgery in the cavity accounts for the majority of urological surgery. Most surgical procedures require indwelling urinary catheters, while minimally invasive resection of bladder tumors and minimally invasive procedures for benign prostatic hyperplasia often require continuous irrigation of the bladder. [0003] Existing urinary catheters often cannot be used as flushing catheters when in use. If the bladder needs to be flushed frequently, the flushing catheters need to be repeatedly inserted into the patient's body, and the urinary catheters need to be repeatedly pulled out and inserted. Increase patient's misery, and...
