Example Embodiment

[0052] Example 1 Striped section 2 Coated urinary catheter

[0053] Please refer to figure 1 , figure 1 It is a schematic structural diagram of a urinary catheter that promotes wound healing and facilitates drainage of the present invention. A urinary catheterization device that promotes wound healing and facilitates drainage. The urinary catheterization device includes a urinary catheter body 10, and two ends of the urinary catheter body 10 are a head end 19 and a tail end 11, respectively. The tail end 11 of the urinary catheter body 10 is provided with three cavities, namely a water injection cavity 12, a medicine injection cavity 13, and a drainage cavity 14, and the tail end 11 also has a unidirectional water injection cavity 12 Valve 15.

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

[0055] Please refer to image 3...

Example Embodiment

[0059] Example 2 Striped section with annular groove + coated urinary catheter

[0060] This embodiment is basically the same as embodiment 1, the difference is: please refer to Figure 5 with Image 6 , The striped section 20 is provided with an annular groove 22 along the length direction of the urinary 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 increasing the coating area, it also prevents the urethra of some patients from tightly fitting with 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 they are arranged at equal intervals along the outer circumference of the stripe section 20. In addition, the depth of the diversion groove 23 is greater than the depth of the annular groove 22, this design does not affect the ...

Example Embodiment

[0061] Example 3 Striped section with annular groove + Se-SiO2 coated urinary catheter

[0062] This embodiment is basically the same as the embodiment 2, and the difference is that: this embodiment uses the Se-SiO2 coating 30 to effectively inhibit the oxidative stress of the prostate wound. The Se-SiO2 coating 30 includes nano-Se-SiO2. The nano-Se-SiO2 material is formed of porous SiO2 material wrapped with Se particles. The porous structure of the porous SiO2 material can effectively control the release rate and dosage of Se, thereby avoiding poisoning. However, the nano-Se-SiO2 material is in powder form , Cannot be coated on the catheter body 10. Since 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 to use it as a drug sustained release agent, and the shell The glycan is in liquid form and can be coated on the catheter body 10. Therefore, in the presen...

Abstract

The invention relates to a urinary catheterization device for promoting wound healing and facilitating drainage. The urinary catheterization device includes a catheter body, and the two ends of the catheter body are respectively a head end and a tail end; The tail end of the urinary catheter body is provided with three cavities, namely the water injection cavity, the drug injection cavity and the liquid discharge cavity; a balloon is provided on the urinary catheter tube body near the head end; The outer surface of the tube is provided with striped protrusions close to the position of the balloon, and the striped protrusions are radially distributed along the outer peripheral surface of the catheter tube and form a striped section, and the adjacent striped protrusions form a The diversion groove is distributed axially along the tube body of the urinary catheter, and the outer periphery of the striped section of the tube body of the urinary catheter is also coated with a coating. Its advantages are as follows: increasing the surface area of ​​the outer coating of the urinary catheter, so that the coating material can obtain a longer action time, thereby achieving a stronger effect, and at the same time, it can drain urine and avoid infection.

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...
