Embodiment 1

[0052] Embodiment 1 Stripe segment 2 Coated type urinary catheter

[0053] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a catheter for promoting wound healing and facilitating drainage in the present invention. A urinary catheterization device that promotes wound healing and facilitates drainage. The urinary catheterization device includes a catheter body 10, and the two ends of the catheter body 10 are a head end 19 and a tail end 11 respectively. The tail end 11 of the catheter body 10 is provided with three cavities, which are water injection chamber 12, drug injection chamber 13, and liquid discharge chamber 14, and the tail end 11 also has a one-way valve for controlling the water injection chamber 12. valve 15.

[0054] Please refer to figure 2 As shown, the head end 19 of the catheter body 10 is respectively provided with a drug injection hole 16 on one side and a liquid discharge hole 17 on one side.

[0055] Please refer to image...

Embodiment 2

[0059] Embodiment 2 striped section with annular groove+coating type urinary catheter

[0060] This embodiment is basically the same as Embodiment 1, the difference is: please refer to Figure 5 and Figure 6 , the striped section 20 is provided with an annular groove 22 along the length direction of the catheter body 10, when the coating 30 is coated on the striped section 20, the annular groove 22 forms a channel for the coating 30 to diffuse up and down, While enlarging the coating area, it also prevents the urethra of some patients from tightly fitting the striped protrusions 21 on the catheter body 10, resulting in uneven distribution of the coating 30 and incomplete utilization. In this embodiment, the number of annular grooves 22 is four, and are arranged at equal intervals along the outer circumference of the stripe segment 20 . In addition, the depth of the diversion groove 23 is greater than the depth of the annular groove 22. This design method does not affect the...

Embodiment 3

[0061] Embodiment 3 has the stripe segment of annular groove+Se-SiO2 coating type urinary catheter

[0062] This embodiment is basically the same as Embodiment 2, the difference is that: this embodiment uses Se-SiO2 coating 30 to effectively inhibit the oxidative stress of the prostate wound, and the Se-SiO2 coating 30 includes nano-Se-SiO2 Material, this nano-Se-SiO2 material is formed by porous SiO2 material wrapping Se particle, the porous structure of porous SiO2 material can effectively control the release rate and dose of Se, thereby avoiding poisoning phenomenon, but described nano-Se-SiO2 material is powdery , cannot be coated on the catheter tube body 10. Because chitosan can be degraded by lysozyme in organisms to generate natural metabolites, it is non-toxic and can be completely absorbed by organisms, so it has great advantages in using it as a drug sustained-release agent, and the shell The polysaccharide is in a liquid state and can be coated on the tube body 10...

Abstract

The invention relates to a catheterizing device for promoting wound healing and bringing the convenience to drainage. The catheterizing device comprises a catheter body, and the two ends of the catheter body are the head end and the tail end respectively; three cavities are formed in the tail end of the catheter body, and are the water injection cavity, the drug injection cavity and the liquid discharging cavity respectively; a ball sac is arranged at the portion, close to the head end, on the catheter body; stripe protrusions are formed in the portion, tightly close to the ball sac, of the outer surface of the catheter body, and are distributed in the radial direction of the periphery face of the catheter body to form a stripe section, guide grooves are formed between the adjacent stripeprotrusions, and are distributed in the axial direction of the catheter body, and the periphery of the stripe section of the catheter body is also coated with a coating. The catheterizing device has the advantages that the superficial area of the outer coating of a catheter is increased, a coating material can have longer effect time, and therefore the higher effect is achieved; meanwhile, urine can be drained, and infection is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheterization device for promoting wound healing and facilitating drainage. Background technique [0002] Prostatic hyperplasia is a common disease in elderly men. The main clinical manifestations are dysuria and urinary tract obstruction, and even hydronephrosis and renal insufficiency. The principle is that endoscopic resection of prostatic hyperplasia under direct vision has the advantages of wide adaptability, no abdominal incision, small trauma, quick recovery, short postoperative bladder flushing time, etc., and has become the gold standard for the treatment of benign prostatic hyperplasia. Ensuring the patency of the postoperative urinary catheter is an important guarantee for good surgical results. [0003] At present, known medical catheters are made of materials such as natural rubber, silicon rubber or polyvinyl chloride (PVC), and can be inserted into the...
