Referring to FIG. 1 and FIG. 2 , this embodiment provides a wound irrigation device 100 , including: a liquid drainage device 101 and a sealing device 105 . The sealing device 105 is arranged around the periphery of the wound 103 , and the drainage device 101 is connected with the sealing device 105 .

In this embodiment, please refer to FIG. 1 and FIG. 2 again, the sealing device 105 is disposed around the periphery of the wound 103 . Since the shape of the wound 103 is not fixed, the shape of the sealing device 105 will change accordingly with the shape of the wound 103 . At the same time, in order to ensure that the closure device 105 will not press against the wound 103 , the size of the closure device 105 will be slightly larger than the size of the wound 103 . Of course, in other embodiments of the present invention, the specific sizes of the closure device 105 and the wound 103 can be selected and adjusted according to requirements, which is not limited in the present invention.

Specifically, the closure device 105 is provided with a lumen 107 corresponding to the wound 103 . When the closing device 105 closes the wound 103, the inner cavity 107 is located above the wound 103 and forms a closed space. This closed space provides a protective barrier for the wound 103, avoids the interference of the external environment, and does not oppress the wound 103, avoiding further infection of the wound 103.

Wherein, the sealing device 105 is also provided with a drip tube 109 for dripping liquid to the wound 103 . The dropper 109 is mainly used for selecting the corresponding medicine for the treatment of the wound 103 . For example, when the wound 103 needs to be cleaned, the dripping liquid contained in the drip tube 109 can be cleaning medicine such as medical distilled water; Drugs: When the wound 103 needs to be treated, the drop contained in the drip tube 109 can be a therapeutic drug for the wound 103, etc., which is not limited in the present invention.

As a preferred solution, the closing device 105 includes a block of water-absorbing material 113 and a closing member 115 for closing the surface of the block of water-absorbing material 113 .

Since the liquid dripped from the drip tube 109 acts on the wound 103, the liquid outlet 117 of the drip tube 109 directly faces the wound 103, which can reduce the waste of the drip and enhance the efficacy of the drip. Of course, in other embodiments of the present invention, since the degree of trauma of the wound 103 is not constant, when the trauma of the wound 103 is very serious, dripping liquid directly corresponding to the wound 103 will aggravate the excessive pain of the patient. position, adjust the distance between the liquid outlet 117 of the dropper 109 and the wound 103, etc., which are not limited in the present invention. And, the dripping tube 109 enters the part of the washing sponge and is facing the wound 103 side half tube with a plurality of holes. At the same time, the sealing connection between the outer wall of the dropper 109 and the closure member 115 can further reduce external pollution, protect the wound 103, and avoid infection. Of course, in other embodiments of the present invention, the way of the sealing connection between the outer wall of the drip tube 109 and the closing member 115 can also be selected and adjusted according to specific requirements, which is not limited in the present invention.

As a preferred solution, the drip tube 109 and the closure member 115 are integrally formed, and there is no gap in the quality inspection of the integrally formed drip tube 109 and the closure member 115, which can further avoid contamination of the wound 103 by the outside world. Meanwhile, the inner cavity 107 is a cavity penetrating through the water-absorbing material block 113 , the sealing member 115 seals the cavity, and the liquid outlet 117 of the drip tube 109 communicates with the cavity. Of course, in other embodiments of the present invention, the connection mode between the drip tube 109 and the closure member 115 can also be selected and adjusted accordingly according to requirements, for example, detachable connection can be selected, which is not limited in the present invention.

In this embodiment, please refer to FIG. 1 and FIG. 2 again, the liquid inlet 111 of the liquid discharge device 101 communicates with the inner cavity 107 . The liquid discharge device 101 is mainly used to effectively and timely discharge the waste liquid generated when cleaning the wound 103, which can not only avoid contamination of the wound 103, but also form a continuous circulation effect, reducing the labor force consumed by repeated operations .

Specifically, the liquid discharge device 101 includes a liquid discharge pipe 121 communicating with the negative pressure suction system 119 , and the liquid inlet 111 of the liquid discharge pipe 121 is disposed in the water-absorbing material block 113 . When the drip tube 109 continuously drips liquid to treat the wound 103, a certain amount of waste liquid will be generated after the treatment, and the water-absorbing material block 113 absorbs and stores this part of the waste liquid. At the same time, the liquid inlet 111 of the drain pipe 121 is set in the water-absorbing material block 113 to effectively extract the partially absorbed and stored waste liquid through the negative pressure suction system 119, so that the water-absorbing material block 113 can continuously flow from The wound 103 absorbs waste liquid, and can continuously use the negative pressure suction system 119 to discharge the absorbed waste liquid through the liquid discharge port 127, thereby ensuring that the liquid dripped by the drip tube 109 will not overflow, and at the same time ensure that the dripping liquid The process of absorbing waste liquid and removing waste liquid is carried out in an orderly manner, thereby improving the treatment efficiency of the wound 103, saving treatment time, effectively protecting the wound 103, avoiding pollution of the wound 103, and protecting the life safety and health of patients.

As a preferred solution, please refer to FIG. 3 , the drain pipe 121 includes a main pipe 123 for communicating with the negative pressure suction system 119 and a plurality of branch pipes 125 communicating with the main pipe 123 . The liquid inlets 111 of the plurality of branch pipes 125 are evenly distributed in the water-absorbing material block 113 . Since the shape of the wound 103 is uncertain, and when the negative pressure suction system 119 extracts a position, some waste liquid may accumulate in the water-absorbing material block 113, so a plurality of branch pipes 125 evenly distributed in the water-absorbing material block 113 are provided. It can effectively discharge waste liquid from various parts, improve absorption efficiency, save action time, and reduce patient treatment time.

In this embodiment, the sealing device 105 can be set as a suction cup seal according to requirements, and the suction cup seal is provided with a liquid inlet 111 communicated with the drip tube 109 and a liquid discharge port 127 communicated with the liquid discharge device 101 . The wound 103 can be effectively protected by the suction cup seal to prevent the wound 103 from being infected.

In this embodiment, referring to FIG. 4 and FIG. 5 , the wound irrigation device 100 can also be provided with a protective gas delivery tube 129 according to requirements, and the gas outlet of the protective gas delivery tube 129 communicates with the inner cavity 107 . The protective gas can be supplied to the inner cavity 107 through the protective gas delivery pipe 129 , so that the protective gas acts on the wound 103 to treat the wound 103 . For example, when the wound 103 is infected with anaerobic bacteria, oxygen can be input into the inner cavity 107 and kept for a period of time before the oxygen can be exhausted. Of course, in other embodiments of the present invention, the type of shielding gas can be selected according to requirements, which is not limited in the present invention.

This embodiment also provides a wound irrigation system (not shown in the figure), including a wound irrigation device 100 .
