Description

Negative pressure drainage tube device

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a negative pressure drainage tube device.

Background

The drainage tube is required to be placed conventionally after the surgical operation, so that pus, blood, urine, exudates and other liquid accumulated in human tissues or body cavities are guided to the outside of the body, and the infection, the wound healing and the like are prevented from occurring after the operation. The most clinically applied at present is a negative pressure drainage tube device, which adopts the principle of negative pressure suction to suck exudates from a wound surface out through a drainage tube, so as to achieve the purposes of removing necrotic tissues, reducing the number of bacteria on the wound surface, relieving edema, accelerating the blood circulation of the wound surface part, remarkably promoting new blood vessels to enter the wound surface and stimulating the growth of granulation tissues, and can directly accelerate the healing of the wound surface or create conditions for surgical repair.

The blockage of the drainage tube becomes a common condition after the surgical operation, particularly, when the retention time of the drainage tube device after the surgical operation is long, tissues at the wound begin to heal and are attached to the drainage tube to cause blockage, for example, an intestinal fistula wound surface is formed when the abdominal wall is infected, and an intestinal oil film is easy to block the drainage tube, so that the drainage is not smooth. The existing back flushing can not effectively remove the oil film, and the blockage problem can be solved only by replacing the drainage tube.

However, when the drainage tube is replaced, the new drainage tube cannot accurately find the position of the wound, and particularly, the new drainage tube cannot accurately position the wound during intestinal fistula drainage, so that the working difficulty of a doctor is increased; in addition, the new drainage tube is easy to cause secondary damage to the patient in the process of inserting the new drainage tube into the organ.

Detailed Description

In order to make the present invention more clear, a negative pressure drainage tube device of the present invention is further described below with reference to the accompanying drawings, and the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

As shown in figure 1, the negative pressure drainage tube device comprises a drainage tube 1, a vent tube 2 and a water injection tube 3, wherein the tube diameters of the vent tube 2 are smaller than those of the drainage tube 1 and the water injection tube 3, and the tube diameters of the drainage tube 1 and the water injection tube 3 are the same. The tubes (drainage tube, vent tube and water injection tube) are all made of medical soft silica gel. The lower parts of the drainage tube 1, the vent pipe 2 and the water injection pipe 3 are respectively provided with a group of small holes 11 which are uniformly distributed along the axial direction, and the small holes 11 are arranged in two rows and symmetrically distributed on the pipe wall on each pipe. The lower parts of the drainage tube 1, the vent pipe 2 and the water injection pipe 3 respectively penetrate through the cap 4 and are arranged in the cylindrical guide body 5, the upper ends of the drainage tube, the vent pipe and the water injection pipe are respectively connected with a conduit joint 10, and the conduit joint 10 can be quickly connected with an external matching instrument, such as a conduit of a negative pressure generating device, an infusion conduit and the like.
