CN211986448U - Drainage tube - Google Patents

Abstract

The utility model discloses a drainage tube, it includes pipe body and dredging pipe, and the built-in end of pipe body one end for stretching into patient's thorax has arranged flowing back end and leading end to the other end of pipe body, dredges the pipe and stretches into the pipe body from the leading end, and the one end shaping that dredging pipe stretched into the pipe body has inflatable sacculus. When the drainage tube needs to be dredged, the saccule is inflated to pull the dredging tube, and the saccule discharges the blockage in the drainage tube to the liquid discharge end so as to be convenient for discharging. The utility model has reasonable structure and can be widely applied to the technical field of medical instruments.

Description

Drainage tube

Technical Field

The utility model relates to the technical field of medical equipment, in particular to drainage tube.

Background

After a thoracic operation, a thoracic drainage tube needs to be placed for drainage, the drainage tube needs to be pulled out when the drainage amount of thoracic fluid is small, but the drainage tube needs to be kept in clinic for a long time, and because thoracic fluid cellulose, blood clots and purulent exudates are attached to the inner wall of the drainage tube, the drainage tube is blocked, and the drainage is influenced, so that the diagnosis is influenced. In order to solve the problem, the current common practice is to replace the drainage tube, which can increase the pain of the patient when the drainage tube is inserted and pulled out and also can increase the clinical cost.

SUMMERY OF THE UTILITY MODEL

For solving the technical problem, dredge the drainage tube, the utility model provides a drainage tube, the technical scheme who adopts as follows:

the utility model provides a drainage tube includes pipe body and dredging pipe, and the built-in end of pipe body one end for stretching into patient's thorax has arranged flowing back end and leading end to the other end of pipe body, dredges the pipe and stretches into the pipe body from the leading end, and the one end shaping that dredging pipe stretched into the pipe body has inflatable sacculus.

Furthermore, the side wall of the placing end is formed with at least one drainage hole.

Furthermore, the section of space from the inner top wall of the placing end to the drainage hole is used for accommodating the saccule.

Further, the inlet of the liquid discharge end is positioned on the side wall of the pipe body.

Has the advantages that: when the drainage tube needs to be dredged, the saccule is inflated to pull the dredging tube, and the saccule discharges the blockage in the drainage tube to the liquid discharge end so as to be convenient for discharging. The utility model has reasonable structure and can be widely applied to the technical field of medical instruments.

Detailed Description

The present invention will be further described with reference to fig. 1 to 2.

The utility model relates to a drainage tube, it includes pipe body 11 and dredge pipe 12, and 11 one ends of pipe body are for stretching into the end 13 of putting into of patient's thorax, and the lateral wall shaping of putting into end 13 has at least one drainage hole 17. The other end of the pipe body 11 is provided with a drain end 14 and a leading end 15, and an inlet of the drain end 14 is located at a side wall of the pipe body 11.

The dredging pipe 12 extends into the pipe body 11 from the leading end 15, an inflatable balloon 16 is formed at one end of the dredging pipe 12 extending into the pipe body 11, and the space from the inner top wall of the placing end 13 to the drainage hole 17 is used for accommodating the balloon 16. This space should be the area between the top wall and the nearest drainage hole 17 in the end 13 where the balloon 16 is initially positioned.

When the blockage appears in the drainage tube, the saccule 16 is inflated, the dredging tube 12 is pulled, and the blockage is discharged to the liquid discharge end 14 to be convenient for discharging. After dredging, the dredging pipe 12 is pushed back to move the saccule 16 to the top of the placing end 13, so that the saccule 16 is prevented from blocking the drainage tube, and meanwhile, the saccule 16 is deflated.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
