Problems solved by technology

Due to the needs of surgery or nursing, it is often necessary to indwell some medical catheters (such as urinary catheters, central venous catheters, etc.) before surgery or postoperatively (such as drainage tubes, etc.). Indwelling in the body for about 1 to 30 days, during the indwelling process of the medical catheter, it is very easy to cause infection of the surrounding cavity or wound surface of the indwelling medical catheter

Embodiment 1

[0016] Example 1 ,Such as figure 1 As shown, the structural representation of the first embodiment of the disposable bacteriostatic super-slippery medical indwelling catheter of the present invention is provided, which includes a tube wall 2, an antibacterial medium layer 3, and a super-slippery medium layer 4; The wall 2, the antibacterial medium layer 3 and the super slippery medium layer 4 constitute the conduit 1. Tube wall 2 is made of medical polymer material, such as polyvinyl chloride, polyurethane, silicon rubber or polylactic acid etc.; To realize the antibacterial and antibacterial effect when the catheter is indwelling, its material can be nano-silver, silver oxide, silver ion, chitosan or antibiotics. The super-slip medium layer 4 is arranged on the outer surface of the antibacterial medium layer 3, and when the catheter is inserted or pulled out of human tissues or organs, the friction force between them is reduced, and the pain of the patient is reduced. The ...

Embodiment 2

[0018] Example 2 ,Such as figure 2 Shown, provided the structural representation of the second embodiment of the present invention, it comprises tube wall 2, antibacterial medium layer 3, super slippery medium layer 4, by tube wall 2, antibacterial medium layer 3 and super slippery medium layer The slip medium layer 4 constitutes the catheter 1; the antibacterial medium layer 3 shown is located on the inner surface of the tube wall 2, and the super slippery medium layer 4 is arranged on the outer surface of the antibacterial medium layer 3. The materials, effects, processing techniques and shapes of the antibacterial medium layer 3, the super-slip medium layer 4 and the pipe wall 2 are all the same as those in Example 1.

Embodiment 3

[0019] Example 3 ,Such as image 3 As shown, the structure diagram of the third embodiment of the present invention is provided, which includes the pipe wall mixed layer 5 and the super slippery medium layer 4, and the conduit 1 is formed by the pipe wall mixed layer 5 and the super slippery medium layer 4; The sliding medium layer 4 is located on the outer surface of the tube wall mixing layer 5, and when the catheter is inserted or pulled out of human tissues or organs, the friction force between them is reduced, and the pain of the patient is reduced. Its material can be selected from liquid paraffin, silicone oil, Polyurethane or polyurethane prepolymer, etc. The pipe wall mixing layer 5 is composed of antibacterial and bacteriostatic components uniformly distributed in the pipe wall 2, such as being uniformly mixed with antibacterial materials such as nano-silver, silver oxide, silver ions, chitosan or antibiotics to polyvinyl chloride, polyurethane, silicon Medical po...

Abstract

The invention relates to a disposable bacteriostatic ultra-smooth medical indwelling catheter, and belongs to the field of medical instruments. The indwelling catheter comprises a catheter wall made of a medical high polymer material, and is characterized in that: an ultra-smooth medium layer for reducing frictional force between the catheter and tissues is arranged on the external surface and / or internal surface of the catheter wall; and a bacteriostatic medium layer is arranged between the catheter wall and the ultra-smooth medium layer. In the indwelling catheter, the ultra-smooth medium layer is arranged on the outermost side of the catheter wall, so that the frictional force between a catheter body and tissues or organs of human bodies is effectively reduced, and the pain of patients is also relieved; and the bacteriostatic medium layer is arranged on the internal surface of the catheter wall or between the catheter wall and the ultra-smooth medium layer, so that the catheter has antibacterial and bacteriostatic functions, the infection caused by the medical indwelling catheter is reduced, the using amount of antibiotics is reduced, and the nursing cost is saved, so the disposable bacteriostatic ultra-smooth medical indwelling catheter has high application and popularization value.

Description

technical field [0001] The invention relates to a disposable bacteriostatic super-slippery medical indwelling catheter, and more specifically relates to a disposable bacteriostatic super-slippery medical indwelling catheter provided with an antibacterial medium layer and a super-slippery medium layer. Background technique [0002] At present, medical catheters are mostly made of medical polymer materials, such as silicone rubber, polyurethane, polyvinyl chloride, etc. Among them, the two polymer materials of silicone rubber and polyurethane have excellent biocompatibility, and have the characteristics of not bonding with body tissues, etc. Beneficial properties, so it has a wide range of applications in the medical field. Due to the needs of surgery or nursing, it is often necessary to indwell some medical catheters (such as urinary catheters, central venous catheters, etc.) before surgery or postoperatively (such as drainage tubes, etc.). The indwelling in the body ranges ...
