Urine catheterization device for urology department

Abstract

The invention provides a urine catheterization device for urology department. The urine catheterization device for the urology department comprises a host, a pump valve assembly, a urethral catheter and a urine bag, wherein the pump valve assembly is detachably arranged on the host; the urethral catheter and the urine bag are respectively connected with the pump valve assembly through hoses; the urethral catheter comprises a catheter body, a connecting cover, a communicating cover, a sac body and a connecting tube part; the connecting cover is connected to one end of the catheter body; the communicating cover is connected onto one end of the connecting cover; the sac body is connected onto one end, near the connecting cover, of the outer wall of the catheter body; the connecting tube partis connected onto one end, far away from the connecting cover, of the catheter body; a heating inner tube a, a heating inner tube b, a sac liquid injection tube and a medicine feeding tube are integrally formed onto the inner wall of the pipe body; a connecting plug a and a connecting plug b with penetrated two ends are respectively formed in positions, corresponding to the heating inner tube a and the heating inner tube b, of one end of the connecting cover; a space for communicating the connecting plug a and the connecting plug b is formed between the communicating cover and the connecting cover; the urethral catheter is matched with a heater, a motor and the pump valve assembly to heat the urethral canal; the goal of preventing the urethral canal edema is achieved.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to the field of urological instruments. Background technique [0002] The invention patent application with document number CN103301514A discloses a multifunctional indwelling catheterization device, which mainly realizes the function of automatic pressure-sensitive urination, and collects urination parameters through sensors, and has an early warning function, which has certain practicability. However, electronic drainage Liquid valves, flow sensors, etc. are directly connected to the urination pipeline. If all parts are disposable, the overall cost of the catheterization device will be too high, which will significantly increase the economic burden of the patient; if the parts are reused, there will be a risk of cross-infection. [0003] The Chinese patent with document number CN205515936U discloses a urinary catheter that can prevent urine leakage and can be treated by heat. It...

Problems solved by technology

However, there are several problems in the technical solution of this patent that make this solution difficult to implement. One is that the structure of the three-layer casing has difficulties in assembling and sealing methods at multiple connection positions. The other is that the heating wire is arranged on the outer tube. The outer wall (accurately speaking, it should be embedded in the tube wall of the outer tube) also has difficulties in processing. Specifically, since one end of the catheter is inserted into the urethra, the heating wire must be inserted from the outer tube of the outer tube at both ends. In order to make the heating wire conduction, the outer tube and the heating wire need to be separately processed and formed
