A urological catheterization device

Abstract

The invention discloses a urinary catheterization device for urology, which comprises a host, a pump valve assembly detachably installed on the host, and a catheter and a urine bag respectively connected to the pump valve assembly through flexible tubes; the catheter includes The tube body, the connecting cover connected to one end of the tube body, the connecting cover connected to one end of the connecting cover, the capsule connected to the outer wall of the tube close to the end of the connecting cover, and the connecting part connected to the end of the tube body away from the connecting cover; the inner wall of the tube There are heating inner tube a, heating inner tube b, capsule liquid injection tube and drug feeding tube formed in one piece, and connecting plugs a and connecting plugs through both ends are respectively formed at the positions corresponding to heating inner tube a and heating inner tube b at one end of the connecting cover. Plug b; a space connecting plug a and plug b is formed between the connecting cover and the connecting cover; the catheter cooperates with the heater, motor and pump valve assembly to heat the urethra to prevent urethral edema.

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
