[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides a negative pressure wound drain, which is mainly used to solve the problem that the waste liquid will flow along the wound to various parts of the patient's skin during the cleaning process of the wound in the prior art, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0020] A negative pressure wound drain comprises a drainage tube 1, one end of the drainage tube 1 is connected to a three-way tube 2, one end of the three-way tube 2 away from the drainage tube 1 is connected to a first connecting tube 3, one end of the first connecting tube 3 away from the three-way tube 2 is connected to a liquid absorbing ball 4, a fitting mechanism 5 is arranged on one side of the outer wall of the first connecting tube 3, the fitting mechanism 5 is used to seal the wound side of the patient to prevent the outflow of cleaning liquid, a cleaning mechanism 6 is arranged on one side of the outer wall of the three-way tube 2, and the cleaning mechanism 6 is used to clean the wound, and its specific components are: comprising a second connecting tube 601 connected to one side of the three-way tube 2, one end of the second connecting tube 601 away from the first connecting tube 3 is symmetrically connected to a third connecting tube 602, a second valve switch 603 is fixedly arranged on one side of the outer wall of the third connecting tube 602, and the third connecting tube 602 An installation box 604 is provided on one side of the outer wall, and a accommodating cavity is symmetrically constructed inside the installation box 604. One end of the third connecting pipe 602 away from the second connecting pipe 601 passes through the installation box 604 and the end is located inside the installation box 604. A liquid suction mechanism 7 is provided on one side of the outer wall of the drainage tube 1. The liquid suction mechanism 7 is used to absorb waste liquid from the wound. Its specific components include: a sleeve 701 connected to the end of the drainage tube 1, a sliding plug 702 is connected to the inner wall of the sleeve 701, a connecting rod 703 is fixedly provided on one side of the sliding plug 702 away from the inner bottom wall of the sleeve 701, an end of the connecting rod 703 away from the sliding plug 702 passes through the sleeve 701 and a handle 704 is fixedly provided on the end, a first valve switch 705 is fixedly provided on one side of the outer wall of the three-way pipe 2, and filter holes are evenly distributed on the outer wall of the liquid suction ball 4.

[0021] The specific operation method and working principle of the device are as follows: during operation, the staff can place the absorbent ball 4 on the patient's wound, and then use the fitting mechanism 5 to seal the skin at the wound. Then the staff can pull the handle 704 to drive the connecting rod 703 and the sliding plug 702 to move away from the inner bottom wall of the sleeve 701, so that the waste liquid at the wound is transported along the first connecting tube 3, the three-way tube 2, and the drainage tube 1 to the inside of the sleeve 701 to complete the drainage of the waste liquid. It should be noted that at this time, the second valve switch 603 is in a closed state, and the first valve switch 705 keeps the drainage tube 1 and the first connecting tube 3 in a connected state. Then, the staff needs to discharge the waste liquid inside the sleeve 701, and then turns the first valve switch 705 to make the drainage tube 1 The second connecting tube 601 is in a connected state, and the drainage tube 1 and the first connecting tube 3 are in a closed state. It should be noted that there are two accommodating chambers inside the installation box 604, one of which is filled with saline and the other is empty. At this time, it is necessary to close the second valve switch 603 connected to the saline accommodating chamber, and open the other second valve switch 603, so that the waste liquid in the sleeve 701 can be transported to the inside of the accommodating chamber. If the wound needs to be cleaned, the connecting rod 703 can be pulled to drive the sliding plug 702 to move, drain the saline into the sleeve 701, and then inject the saline into the patient's wound, and then continue to transport the waste liquid inside the wound to the inside of the accommodating chamber with the waste liquid.

[0022] like Figure 1 and Figure 3 As shown, in some embodiments, the fitting mechanism 5 includes a tape 501 fixed to the outer wall of the first connecting tube 3, and a protective cotton 502 is fixed to a side of the tape 501 close to the absorbent ball 4. The operating principle and working method of the fitting mechanism 5 are that during the working process, the staff can place the protective cotton 502 on the patient's wound, and then stick the tape 501 to the skin around the patient's wound, so that the tape 501 and the skin are closely fitted, thereby preventing waste liquid from flowing out along the patient's wound, and also preventing waste liquid from flowing out along the wound when washing with saline.

[0023] like Figure 1 As shown, in some embodiments, a liquid receiving port 8 is symmetrically constructed on one side of the top surface of the installation box 604 above the accommodating cavity. More specifically, the liquid receiving port 8 is for facilitating the placement of physiological saline and cleaning of the accommodating cavity.

[0024] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
