Abstract

A drainage tube comprises a drainage tube body and titanium metal arranged on the drainage tube body. The utility model has the advantages that: the section of the drainage tube which penetrates out of the skin from the body is provided with titanium metal, so that a gap between the outer surface of the drainage tube and the skin is filled with the titanium metal, and the titanium metal has good biocompatibility, can be adhered with cells on the surface and can be tightly connected with surrounding skin tissues to close the gap between the drainage tube and the skin, thereby preventing retrograde infection caused by the drainage tube.

Description

Drainage tube

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a drainage tube of outside pathogen retrograde infection.

Background

The drainage tube is a medical appliance for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. Generally made of silicone rubber or polyurethane. When in use, one end of the drainage tube is inserted into the drainage position of the body or the wound surface, the other end of the drainage tube can be connected with other external apparatuses such as a drainage connecting tube and the like in vitro, and the drainage tube is placed in the operation area or the body cavity of the human body and penetrates out of the body through a skin incision by utilizing the siphon or negative pressure suction principle to guide pus, exuded blood, tissue fluid and other fluids accumulated in the tissues or the body cavity of the human body to the outside of the body, thereby preventing postoperative infection caused by fluid deposition and promoting wound healing and disease rehabilitation.

However, the existing drainage tube is only a tubular object, and the part of the drainage tube which penetrates out of the skin from the wound surface has no special structure, so that once the drainage tube is placed for a long time clinically, external pathogenic bacteria can reversely enter the wound from the outer surface of the drainage tube, and complications such as infection and the like are caused.

Therefore, effective innovation is needed to overcome the defects of the prior art.

Disclosure of Invention

An object of the utility model is to provide a drainage tube, this drainage tube are provided with titanium at the pipeline section part of wearing out skin from the internal for the gap is filled by titanium between drainage tube surface and the skin, thereby prevents the retrograde infection that the drainage tube arouses.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a drainage tube comprises a drainage tube body and titanium metal arranged on the drainage tube body;

correspondingly, the titanium metal is arranged in a tubular shape and sleeved on the drainage tube body.

The utility model has the advantages that: the section of the drainage tube which penetrates out of the skin from the body is provided with titanium metal, so that a gap between the outer surface of the drainage tube and the skin is filled with the titanium metal, and the titanium metal has good biocompatibility, can be adhered with cells on the surface and can be tightly connected with surrounding skin tissues to close the gap between the drainage tube and the skin, thereby preventing retrograde infection caused by the drainage tube.

in the figure:

1. a drainage tube body; 2. titanium metal.

Detailed Description

The utility model discloses an embodiment, the drainage tube includes drainage tube body 1 and sets up titanium metal 2 on drainage tube body 1, drainage tube body 1 is the tubular structure that current adoption silicon rubber or polyurethane made promptly, in this embodiment, in order to set up titanium metal 2 on drainage tube body 1, set up titanium metal 2 into this kind of tubular structure of titanium pipe or possess the cyclic annular structure of certain length usually, the mode zero clearance cover that the accessible cover was established is tight on drainage tube body 1, of course, also can adopt other modes to set up titanium metal 2 on drainage tube body 1, for example welding etc.. In the using process, the titanium metal 2 is required to be just right at the position penetrating out of the skin, the titanium metal 2 has good biocompatibility, the surface of the titanium metal 2 can be adhered with cells and can be tightly connected with surrounding tissues to seal a gap between the drainage tube and the skin, and therefore retrograde infection caused by the drainage tube is prevented.

The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.

Claims (1)

1. A drainage tube is characterized by comprising a drainage tube body and titanium metal arranged on the drainage tube body, wherein the titanium metal is arranged in a tubular shape and is sleeved on the drainage tube body without clearance.
