Problems solved by technology

But the existing closed negative pressure drainage tube is just a common plastic hose with some side holes. During use, the drainage tube is often blocked due to the exudate in the wound is more or thicker, and the drainage tube Once it cannot be dredged, the whole set of expensive closed negative pressure drainage and wound protection materials will be scrapped immediately
Replacing the wound protection material will lead to the interruption of treatment and a large increase in medical expenses. At this time, if the drainage tube can be effectively dredged, the whole set of wound protection materials can continue to be used effectively
In recent years, someone has designed a drainage tube with a thinner side tube used as a flushing tube, but simple flushing is difficult to effectively clear the obvious blockage, and the improvement of the overall effect is very limited

example 1

[0014] As shown in Figure 1, the drainage tube 1 of the present invention is a soft plastic tube with a plurality of side holes in the front section. The cleaning channel tube 2 with the same diameter, the angle between the cleaning channel tube 2 and the drainage tube 1 is 10-20°, the cleaning channel tube 2 is equipped with a cleaning brush 3, and the brush rod 4 of the cleaning brush 3 is made of elastic material Its length is slightly longer than the length of the pipeline from the tail end of the cleaning channel tube 2 to the head end of the drainage tube 1. The head end of the brush bar 4 is a needle 5, and the rear of the needle 5 is a cleaning brush head 6, and the outer contour diameter of the cleaning brush head 6 is slightly larger than the inner diameter of the drainage tube 1. The tail end of the brush bar 4 has a brush handle 7. The tail end of the cleaning channel pipe 2 is provided with a pipe joint 8, one end of which has an internal threaded port 9, and the...

[0017] Concrete operation process of the present invention:

[0018] Before use, check whether the brush rod 4 can slide and rotate freely in the center hole of the pipe joint 8, and check whether the tail end of the cleaning channel pipe 2 and the internal thread 9 and the "O"-shaped sealing ring 10 are in an airtight state. Sleeve the open end of the brush bar operating space sealing sleeve 12 on the anti-retraction interface seat 11 of the pipe joint 8 and tighten it. Pull the brush handle 7 to pull the brush rod 4 together with the cleaning brush head 6 into the lumen of the cleaning channel tube 2. At this time, the lumen of the drainage tube 1 remains unobstructed. A safety plug 15 is inserted into the opening of the front end of the drainage tube 1 to prevent the puncturing needle 5 from stretching too far forward and piercing the outer dressing when cleaning. During use, if the lumen of the main drainage tube 1 of the side hole section is found to be clogged, hold the...

Abstract

The invention discloses an airtight type drainage tube inner wall cleaning device. According to the airtight type drainage tube inner wall cleaning device, the pipe wall of the middle section of a drainage tube is provided with a cleaning channel tube which is identical to the drainage tube in diameter; a cleaning brush is mounted inside the cleaning channel tube, the tail end of the cleaning channel tube is provided with a tube joint, one end of the tube joint is provided with an internal thread port, the tail end of the cleaning channel tube is threadedly connected with the internal thread port, and an O-shaped seal ring is mounted between the connecting end surfaces of the cleaning channel tube and the internal thread port; the other end of the tube joint is provided with a retaining socket port, and a cleaning rod operating space closing sleeve made of soft airtight materials sleeves the retaining socket port. The airtight type drainage tube inner wall cleaning device has the advantages of effectively avoiding wound protecting material scrapping due to blocking of the drainage tube, prolonging the usage time of wound protecting materials, reducing waste, saving medical cost and facilitating repeated cleaning operation.

Description

technical field [0001] The invention relates to an airtight drainage pipe wall cleaning device. Background technique [0002] Closed negative pressure drainage is a surgical wound treatment method that has only become popular in recent years. It uses special medical foam material and drainage tube to form a complete set of wound protection materials. The drainage tube is connected with an external negative pressure suction device to achieve sufficient drainage of the wound. Since it was invented by the Germans in the 1990s, it is rapidly becoming popular all over the world. Its unique principle and good curative effect are widely praised by medical personnel all over the world. But the existing closed negative pressure drainage tube is just a common plastic hose with some side holes. During use, because the exudate in the wound is more or thicker, the drainage tube is often blocked, and the drainage tube Once it cannot be dredged, the whole set of expensive closed negative...
