Urology urinary catheterization set

Abstract

The invention discloses a urology urinary catheterization set which comprises a host, a pump valve component, a urinary catheter and a urine bag, wherein the pump valve component is detachably mountedon the host and connected with the urinary catheter and the urine bag through hoses. The urinary catheter comprises a catheter body, a connecting cover, a communication cover, a bag and a catheter connecting portion, the connecting cover is connected at one end of the catheter body, the communication cover is connected at one end of the connecting cover, the bag is connected at one end of the outer wall of the catheter body close to the connecting cover, the catheter connecting portion is connected at one end of the catheter body far away from the connecting cover, a heating inner pipe a, a heating inner pipe b, a bag liquid injection pipe and a drug feeding pipe are integrally formed on the inner wall of the catheter body, a connecting plug a and a connecting plug b are formed at one endof the connecting cover and correspond to the heating inner pipe a and the heating inner pipe b, two ends of the connecting plug a and a connecting plug b are communicated, a space is formed betweenthe communication cover and the connecting cover and communicated with the connecting plug a and the connecting plug b, the urinary catheter is matched with the heater, a motor and the pump valve component to heat a urethra, and edema of the urethra is prevented.

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
