[0027] As a preferred embodiment of the present utility model, Figure 1 The indication is a schematic diagram of the structure of a device for changing dressing after preauricular fistula abscess incision surgery when hanging on the ear, such as Figure 1 As shown, a device for changing dressing after preauricular fistula abscess incision surgery comprises:

[0028] The Y-shaped tube includes a main tube 11, a first branch tube 12, and a second branch tube 13, and both are soft tubes. The first branch tube 12 and the second branch tube 13 extend outward from a first end of the main tube 11. When the device is used, the second branch tube 13 is placed behind the ear, so that the Y-shaped tube can be hung on the ear through the second branch tube 13, which is convenient for doctors to operate and use;

[0029] A negative pressure drainage component 2, the negative pressure suction component is installed on the first branch pipe 12, the negative pressure drainage component 2 is used to provide a negative pressure drainage function, and in this device, is used to guide the fluid to flow in the pipe;

[0030] The closing component 3 is installed on the second branch pipe 13, and the closing component 3 is used to open or close the extension end of the second branch pipe 13, so that

[0031] When the sealing component 3 is in the open state, the flow channel of the first branch pipe 12 of the first branch pipe 12 is connected with the flow channel of the main pipe 11 of the main pipe 11 to form a first passage, and the liquid medicine is input through the extended end of the second branch pipe 13 and flows to the wound through the first passage;

[0032] When the closing component 3 is in a closed state, the flow channel of the second branch tube 13 of the second branch tube 13 is connected with the flow channel of the main tube 11 of the main tube 11 to form a second passage, and the negative pressure drainage component 2 drains pus or cleansed liquid medicine from the wound through the second passage.

[0033] A device for changing dressings after preauricular fistula abscess incision surgery in this embodiment comprises a Y-shaped tube, a negative pressure drainage component 2 and a sealing component 3, wherein the tube comprises a main tube 11, a first branch tube 12 and a second branch tube 13, wherein the first branch tube 12 and the second branch tube 13 extend outward from the first end of the main tube 11, and the negative pressure drainage component 2 and the sealing component 3 are respectively arranged on the first branch tube 12 and the second branch tube 13. When using the device, by placing the open end of the main tube 11 at the wound of the child and fixing it with adhesive tape, the first branch tube 12 flow channel of the first branch tube 12 is connected with the main tube 11 flow channel of the main tube 11 to form a first passage, and when the sealing component 3 is opened, liquid medicine is input into the wound, and the second branch tube 13 flow channel of the second branch tube 13 is connected with the main tube 11 flow channel of the main tube 11 to form a second passage, and when the sealing component 3 is closed, the pus at the wound is drained and output by the negative pressure drainage component 2, thereby reducing the frequent tearing of the adhesive tape to open the wound of the child for debridement, thereby reducing the pain of the child.

[0034] When the device is in use, when the closing component 3 is in an open state, it indicates that the wound needs to be medicated through the first passage; when the closing component 3 is in a closed state, it indicates that the pus at the wound or the cleaned medicine needs to be drained out through the second passage. In this embodiment, the second end of the main pipe 11 is the open end of the main pipe 11. In this solution, it is used for the outflow of medicine and the inflow of pus. An expandable sponge 4 is provided at the second end of the main pipe 11. The expandable sponge 4 covers the second end of the main pipe 11. The expandable sponge 4 can absorb the medicine so that it can diffuse to various parts of the wound of the child. In addition, when it is necessary to drain the pus, the expandable sponge 4 can also absorb the pus to facilitate the guided output.

[0035] During specific use, the open end of the main tube 11 is placed on the wound of the child and fixed with adhesive tape, and the expandable sponge 4 is placed under the adhesive tape. When the expandable sponge 4 absorbs pus or liquid medicine, the absorption capacity of the expandable sponge 4 will be limited due to the limitation of the adhesive tape, that is, the expandable sponge 4 is saturated with absorption, and as the pus is guided out, it is equivalent to releasing the absorption limitation of the expandable sponge 4. This is repeated, combined with the expansion sponge 4's own absorption function for liquid fluids, so that the pus can be drained out.

[0036] Furthermore, when changing the dressing for the child, the sealing component 3 is opened to input the medicine through the first channel, and then the sealing component 3 is closed to drain the pus or the medicine after debridement through the second channel and the negative pressure drainage component 2. The expandable sponge 4 serves as the area for the medicine to enter or the pus to be discharged. By checking the liquid state in the expandable sponge 4, it can be judged whether the child's wound can be cleaned, thereby achieving the purpose of dressing change and debridement.

[0037] As a preferred example, Figure 1 As shown, a plurality of side holes 111 are opened on the outer periphery of the second end of the main pipe 11, and the plurality of side holes 111 are connected to the main pipe 11 flow channel of the main pipe 11. The setting of the plurality of side holes 111 is equivalent to adding a plurality of outlets for inputting the medicine into the expansion sponge 4 or the wound, or adding a plurality of outlets for draining pus or the medicine after debridement, which can improve the efficiency of dressing change.

[0038] In addition, the expansion sponge 4 serves as an area for the entry of drug solution and the exit of pus or drug solution after cleaning, and the expansion sponge 4 covers a plurality of side holes 111 .

[0039] In this embodiment, as a specific example, Figure 1 As shown, the negative pressure drainage component 2 includes:

[0040] A suction bag 21, wherein the suction bag 21 is detachably arranged at the extended end of the second branch pipe 13;

[0041] A negative pressure switch valve 22, wherein the negative pressure switch valve 22 is installed in the flow channel of the second branch pipe 13 of the second branch pipe 13;

[0042] The air pressure in the second passage is adjusted by opening / closing the negative pressure switching valve 22 .

[0043] Among them, the suction bag 21 is used to collect the pus or the medicine after debridement that flows in through the second channel. At the same time, the suction bag 21 is detachably connected to the second branch tube 13, so that the suction bag 21 can be removed. While realizing the device of this embodiment can be reused, it is convenient to seal the pus or the medicine after debridement, which is beneficial for doctors to use it for medical research.

[0044] In addition, the negative pressure switch valve 22 is arranged in the flow channel of the second branch pipe 13 of the second branch pipe 13. When the closing component 3 is closed, the Y-shaped tube is in a closed state. The negative pressure switch valve 22 draws air from the inside of the tube to reduce the air pressure in the tube, thereby achieving the purpose of drainage.

[0045] In this embodiment, if Figure 1 As shown, the closing component 3 is a cylindrical cover, and the cylindrical cover matches the shape of the extended end of the first branch pipe 12; the inner circumference of the cylindrical cover has an internal thread, and the outer circumference of the extended end of the first branch pipe 12 has an external thread, and the cylindrical cover is connected to the extended end of the first branch pipe 12 through a threaded connection, thereby facilitating the function of closing / opening the first channel.

[0046] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
