Description

Drainage tube for wound in lumen

Technical Field

The invention relates to the field of medical instruments, in particular to a drainage tube for an intraluminal wound for human sinus.

Background

The existing drainage tube cannot thoroughly wash the pustule sinus, and the blockage is frequently caused during suction.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a drainage tube for intraluminal wounds capable of sterilizing the skin abscess.

The purpose of the invention is realized by the following technical scheme:

a drainage tube for an intraluminal wound comprises a suction tube, a steel wire, a luer or a locking connector, a flushing port, a flushing tube and a flushing end part; a plurality of flow holes are uniformly formed in the flushing pipe; one end of the flushing pipe is a closed end, the other end of the flushing pipe is provided with the flushing end part, the flushing end part is provided with the flushing port, the suction pipe is arranged inside the flushing pipe, one end of the suction pipe is close to the closed end of the flushing pipe, and the other end of the suction pipe extends through the flushing pipe and the flushing end part; the suction tube forms a cavity with the flushing tube and the flushing end part respectively for injecting medicament; the other end of the suction tube, which is positioned outside the flushing tube, is connected with the luer or the locking joint; the steel wire can be inserted or drawn out from the suction tube; the steel wire plays a supporting role in being inserted into the sinus; the luer or the locking joint is a suction port and can be connected with a suction device.

Further, the outer surface of the flushing pipe is provided with a lubricating coating conforming to biocompatibility.

Furthermore, the inner wall of the flushing pipe and the outer surface of the suction pipe are provided with a coating for preventing the physiological tissue fluid from being hydrophilic.

Compared with the prior art, the invention has the following characteristics and progresses:

the drainage tube for the wound in the tube cavity adopts the structure that the washing tube is arranged outside the drainage tube, the suction tube is arranged inside the drainage tube, and the washing tube is uniformly provided with a plurality of circulation holes, so that the medicine can be uniformly distributed on the wound dressing and further uniformly distributed on the wound, the whole wound can play a good disinfection role, the suction speed can be greatly accelerated, and the effect of quickly cleaning dirty blood can be achieved; when the drainage tube is inserted into the sinus, the steel wire is arranged in the suction tube, so that the support effect can be achieved; the outer surface of the flushing pipe is provided with a lubricating coating which is in accordance with biocompatibility, so that the drainage pipe can be conveniently plugged or pulled out; the inner wall of the flushing pipe and the outer surface of the suction pipe are provided with the physiological tissue fluid hydrophilic prevention coatings, so that the medicament has better fluidity and can not be adhered to the inner wall of the flushing pipe and the outer surface of the suction pipe, and the medicament is saved.

Detailed Description

The invention is further described below with reference to the figures and examples.

As shown in fig. 1-5, a drainage tube for intraluminal wound comprises a suction tube 3, a steel wire 1, a luer or locking connector 2, a flushing port 4, a flushing tube 5, and a flushing end portion 6; a plurality of flow holes 7 are uniformly arranged on the flushing pipe 5; one end of the flushing pipe 5 is a closed end, the other end is provided with a flushing end part 6, a flushing opening 4 is arranged on the flushing end part 6, the suction pipe 3 is arranged inside the flushing pipe 5, one end of the suction pipe 3 is close to the closed end of the flushing pipe 5, and the other end extends through the flushing pipe 5 and the flushing end part 6; the suction tube 3 forms a cavity with the flushing tube 5 and the flushing end part 6 respectively for injecting medicament; the other end of the suction tube 3, which is positioned outside the flushing tube 5, is connected with a luer or a locking joint 2; the steel wire 1 can be inserted or drawn out from the suction tube 3; the steel wire 1 plays a supporting role in being inserted into the sinus; luer or locking connector 2 is a suction port to which a suction device can be attached.

Further, the outer surface of the irrigation tube 5 is provided with a biocompatible lubricating coating.

Furthermore, the inner wall of the flushing pipe 5 and the outer surface of the suction pipe 3 are provided with a coating for preventing the hydrophilicity of the physiological tissue fluid.

The use method of the drainage tube for the intraluminal wound comprises the following steps: (1) the drainage tube is plugged into the pustule in the skin along the sinus direction through the sinus orifice; (2) injecting normal saline or medicament into the flushing port 4, and flowing to the pustule in the skin through the flushing pipe 5; (3) drawing out the steel wire 1, and connecting a suction device at a luer or a locking joint 2; (4) the suction device is started to suck out the pus and blood with normal saline or medicament, thereby achieving the disinfection effect.
