Description

Technical Field

[0001] This invention relates to the field of dressing devices, and in particular to a dermatological dressing device for burns. Background Technology

[0002] Burns are tissue damage caused by contact between the human body and hot liquids (such as boiling water, hot oil, molten steel), hot solids (such as heated metal), or hot steam without a flame.

[0003] Currently, when treating patients' arm wounds, medical staff first apply ointment to the wound with a cotton swab, and then apply a dressing made of hydrophilic colloid (this dressing can absorb exudate to form a gel and maintain a moist environment for the wound). When applying the dressing, medical staff will pinch the skin around the wound to reduce skin tension and ensure the dressing is applied stably. However, the existing procedure has two problems: first, the cotton swab can easily irritate the wound during the application of ointment, causing discomfort to the patient; second, when using a cotton swab that has been used to apply ointment to pick up more ointment, wound fluid may be carried to the ointment container outlet, causing ointment contamination. Therefore, this invention provides a dermatological burn dressing device to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dermatological burn dressing device. By setting up a drug delivery component, it can not only reduce the pain of the patient's wound when applying the ointment, but also replenish the wound with the required ointment during the application process, while avoiding the contamination of unused ointment by wound tissue fluid. This solves the problems of cotton swabs irritating the patient's wound and contaminating unused ointment.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A dermatological burn dressing device includes a handle. A sliding part is formed on the outer wall of the handle near one end. An insertion tube and two locking plates are fixedly connected to the end of the sliding part away from the handle. A locking protrusion is fixedly connected to the outer wall of the locking plate near the insertion tube. A connecting groove is formed on the top wall of the sliding part. A first abutment plate is fixedly connected to the inner wall of the connecting groove away from the insertion tube. A second clearance groove is formed along the length of the connecting groove. The second clearance groove extends to the top inner wall of the handle and communicates with the connecting groove.

[0007] The handle is equipped with a drug delivery component, which is used to deliver medication while applying it.

[0008] Optionally, the drug delivery assembly includes a tube slidably connected within the grip and a drug application head sleeved on the cannula, with a first rotating handle rotatably connected to one end of the tube, the first rotating handle protruding outside the grip.

[0009] Optionally, a third clearance groove is provided on the outer wall of the end of the insert near the first rotating handle, and a fourth clearance groove is provided on the outer wall of the end of the application head away from the insert. A medication application channel is provided at the connection between the application head and the insert, and the medication application channel is connected to the fourth clearance groove.

[0010] Optionally, a partition is fixedly connected to the inner wall of the middle part of the insert, a piston is slidably connected to the inner wall of the insert, and a U-shaped rack is fixedly connected to the outer wall of the piston near the partition.

[0011] Optionally, the medicine application head has symmetrically formed locking grooves on both outer walls near the end of the insertion tube, and a first clamping plate is fixedly connected to one outer wall of the medicine application head. A first clamping rubber is slidably connected to the outer wall of the first clamping plate away from the medicine application head.

[0012] Optionally, a medicated ball is rotatably mounted on the inner wall of the fourth clearance groove, a first limiting post is fixedly connected to the inner wall of one end of the fourth clearance groove, and a clearance circular hole is opened on the inner wall of the other end of the fourth clearance groove. The positions of the first limiting post and the clearance circular hole are symmetrical about the central axis of the fourth clearance groove.

[0013] Optionally, a C-shaped tube is fixedly connected to one end of the application head away from the insertion tube, and a second limiting post is fixedly connected to the other end of the C-shaped tube.

[0014] Optionally, a second clamping plate is slidably connected to the outer wall of the U-shaped rack away from the piston, a second rotating handle is screwed to one side of the outer wall of the second clamping plate, and a second clamping rubber is slidably connected to the outer wall of the second clamping plate away from the second rotating handle.

[0015] Optionally, a sliding ring is slidably connected to the outer wall of the sliding part, and sliding protrusions are symmetrically fixedly connected to the inner wall of the sliding ring. A first sliding groove is provided on the top of both sides of the sliding part, and the sliding protrusion is slidably connected to the corresponding first sliding groove. A movable plate is installed on the top outer wall of the sliding ring.

[0016] Optionally, a C-shaped elastic plate is fixedly connected to the inner wall of the sliding ring near the movable plate, and a second abutment plate is fixedly connected to the end of the C-shaped elastic plate away from the movable plate.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting up a drug delivery component, not only can the pain at the wound site be reduced when applying the ointment, but the ointment can also be replenished to the wound during the application process, avoiding contamination of unused ointment by wound tissue fluid. In addition, after the application is completed, the skin tension at the wound site can be reduced by squeezing the skin around the wound, making it easier for medical staff to apply dressings to the patient's wound. At the same time, the device is easy to install and disassemble, which is convenient for filling ointment and also facilitates subsequent cleaning and disinfection.

[0019] By incorporating a cartridge, a first rotating handle, a piston, a U-shaped rack, a sliding ring, a movable plate, a C-shaped elastic plate, and a second contact plate within the drug delivery assembly, the movable plate can be pushed to cause the piston to slide along the inner wall of the cartridge, thereby pushing out the ointment inside the cartridge. Furthermore, the first rotating handle can be rotated to install the cartridge into or remove it from the handle. This simple installation and removal method facilitates the filling of ointment.

[0020] By incorporating a drug application head, drug application channel, drug application ball, C-shaped tube, first limiting post, and second limiting post within the drug delivery assembly, not only can patient discomfort be reduced when applying ointment to the wound, but the ointment can also be replenished to the drug application ball while applying the ointment; furthermore, the drug application head and drug application ball can be disassembled separately for subsequent cleaning of the device.

[0021] By setting a first splint, a first clamping rubber, a second splint, and a second clamping rubber on the drug delivery component, the tension of the patient's wound can be reduced by squeezing the skin after the ointment is applied, so that the dressing can be applied, thereby promoting the subsequent recovery of the patient's wound.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0035] The following is a detailed description of a dermatological burn dressing device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0036] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides a dermatological burn dressing device, including a handle 1. A sliding part 2 is provided on the outer wall of the handle 1 near one end. An insertion tube 3 and two locking plates 4 are fixedly connected to the end of the sliding part 2 away from the handle 1. The locking plates 4 are S-shaped plastic plates that deform along their bending direction when subjected to force. The two locking plates 4 are symmetrical about the insertion tube 3. A locking protrusion 5 is fixedly connected to the outer wall of the locking plate 4 near the insertion tube 3. The locking protrusion 5 is a semi-circular plastic column. A sliding part 2 is provided on the top wall. There is a connecting groove 201, which is a square groove. A first contact plate 8 is fixedly connected to the inner wall of the connecting groove 201 away from the insertion tube 3. The first contact plate 8 is a square plastic plate, and the open end of the first contact plate 8 is provided with an inclined surface. A second clearance groove 7 is provided along the length of the connecting groove 201. The second clearance groove 7 extends to the top inner wall of the handle 1. The second clearance groove 7 is a square groove and is connected to the connecting groove 201. The drug delivery component is connected to the handle 1, and the drug delivery component can apply medicine while delivering medicine.

[0038] This application, by setting up a drug delivery component, can not only reduce the pain of patients at the wound site when applying ointment, but also replenish the wound with the required ointment during the application process, avoiding contamination of unused ointment by wound tissue fluid. In addition, after application, the tension of the skin at the wound site can be reduced by squeezing the skin around the patient's wound, making it easier for medical staff to apply dressings to the patient's wound. At the same time, this device is easy to install and disassemble, which is convenient for filling ointment and also facilitates subsequent cleaning and disinfection.

[0039] like Figures 1 to 7As shown, the drug delivery assembly includes a tube 9 slidably connected to the inner wall of the handle 1. One end of the tube 9 is rotatably connected to a first rotating handle 10. A third clearance groove 11 is provided on the outer wall of the end of the tube 9 near the first rotating handle 10. A partition 12 is fixedly connected to the inner wall of the tube 9 near the middle. A piston 13 is slidably connected to the inner wall of the tube 9. A U-shaped rack 14 is fixedly connected to the outer wall of the piston 13 near the partition 12. A sliding ring 15 is slidably connected to the outer wall of the sliding part 2. Sliding protrusions 16 are symmetrically fixedly connected to the inner wall of the sliding ring 15. A movable plate 19 is fixedly connected to the outer wall of the top of the sliding ring 15. A C-shaped elastic plate 17 is fixedly connected to the inner wall of the sliding ring 15 near the movable plate 19. A second abutment plate 18 is fixedly connected to the end of the C-shaped elastic plate 17 away from the movable plate 19. The top of both sides of the sliding part 2 is provided with a first sliding groove 6, and the extension direction of the first sliding groove 6 is the same as the length direction of the sliding part 2. The sliding protrusion 16 is slidably connected in the first sliding groove 6. A movable plate 19 is installed on the top outer wall of the sliding ring 15.

[0040] Specifically, the insert 9 is a hollow plastic cylinder, and the outer wall contour of the insert 9 matches the inner wall contour of the handle 1, so the insert 9 can slide on the inner wall of the handle 1. The first rotating handle 10 protrudes from the handle 1 and is rotatably connected to one end of the insert 9. The first rotating handle 10 consists of two parts: a plastic circular plate with anti-slip grooves on its outer wall and a hollow plastic cylinder with threads on its outer wall. The first rotating handle 10 is fitted onto one end of the insert 9, and the outer wall contour of the insert 9 near the first rotating handle 10 matches the contour of the groove on the first rotating handle 10. The first rotating handle 10 can rotate at one end of the insert 9. Since the outer contour of the threaded portion of the first rotating handle 10 matches the inner contour of the threaded end of the handle 1, the first rotating handle 10 can be screwed onto the inner wall of the end of the handle 1 furthest from the insert 3. The partition 12 is fixedly connected to the inner wall of the insert 9 near the middle. The partition 12 is a hollow plastic disc that divides the internal space of the insert 9 into two chambers. The piston 13 is slidably connected to the inner wall of the chamber of the insert 9 furthest from the first rotating handle 10. The piston 13 is a conventional... The technology is publicly available and will not be elaborated upon. When the piston 13 slides along the inner wall of the insert 9 away from the first rotating handle 10, the ointment in the chamber can be pushed out from the end of the insert 9 away from the first rotating handle 10. One end of the U-shaped rack 14 is fixedly connected to the outer wall of the piston 13 near the partition 12. The U-shaped rack 14 is a U-shaped plastic plate, and the outer wall of the U-shaped rack 14 near the top of the handle 1 has teeth. Since the outline of the U-shaped rack 14 matches the inner wall outline of the third clearance groove 11, the U-shaped rack 14 moves away from the piston 13. One end passes through the inner wall of the third clearance groove 11, and the U-shaped rack 14 can slide on the inner wall of the third clearance groove 11. Since the outer contour of the U-shaped rack 14 matches the inner contour of the second clearance groove 7 mentioned above, the U-shaped rack 14 can slide on the inner wall of the second clearance groove 7. The sliding protrusion 16 is a semi-circular plastic column, and the outer contour of the sliding protrusion 16 matches the inner contour of the first sliding groove 6 mentioned above. The first sliding groove 6 can provide a limiting effect for the sliding protrusion 16 to prevent the sliding ring 15 from shaking when sliding.

[0041] The outer wall of the movable plate 19, away from the sliding ring 15, has several segmented grooves arranged in a linear array. This prevents medical personnel from slipping their fingers when pressing the movable plate 19. One end of the C-shaped elastic plate 17 is fixedly connected to the inner wall of the sliding ring 15 near the movable plate 19. The C-shaped elastic plate 17 is a C-shaped plastic plate. When the C-shaped elastic plate 17 is subjected to force, it will deform along its bending direction. The second abutment plate 18 is an inclined plastic plate. The end of the second abutment plate 18 away from the C-shaped elastic plate 17 can abut against the teeth on the U-shaped rack 14 (U-shaped). One end of the rack 14 extends along the second clearance groove 7 and passes through the connecting groove 201 (i.e., through the sliding ring 15). When medical staff push the movable plate 19, the second abutment plate 18 will abut against the teeth of the U-shaped rack 14, causing the U-shaped rack 14 to slide along the inner wall of the second clearance groove 7. The C-shaped elastic plate 17 and the second abutment plate 18 cooperate to form an overall profile that matches the inner wall profile of the connecting groove 201 mentioned above. The connecting groove 201 can provide clearance space for the movement of the C-shaped elastic plate 17 and the second abutment plate 18 when the movable plate 19 is pushed or pulled.

[0042] When medical staff prepare to insert the ointment, they first inject the ointment into the end of the insert 9 away from the first rotating handle 10. Then, they insert the insert 9 into the end of the handle 1 away from the intubation tube 3, allowing the insert 9 to slide along the inner wall of the handle 1 until the end of the insert 9 away from the first rotating handle 10 touches the inner wall of the handle 1 near the intubation tube 3. Then, they rotate the first rotating handle 10 clockwise to screw it into the end of the handle 1 away from the intubation tube 3, thus completing the installation of the insert 9. When medical staff press the movable plate 19 towards the first rotating handle 10, the sliding ring 15 will slide along the outer wall of the sliding part 2 towards the first rotating handle 10 under the action of the movable plate 19. The C-shaped elastic plate 17 and the second contact plate 18 move synchronously with the sliding ring 15. At this time, the second contact plate 18, under the action of the inclined surface of the U-shaped toothed rack 14, causes the C-shaped elastic plate 17 to move. 7 is subjected to force and deforms along its bending direction; then, under the elastic action of the C-shaped elastic plate 17, it recovers its deformation, causing the second abutment plate 18 to abut against the next interval in the teeth of the U-shaped rack 14. Then, the medical staff pushes the movable plate 19, which causes the sliding ring 15 to slide along the outer wall of the sliding part 2 toward the insertion tube 3. The C-shaped elastic plate 17 and the second abutment plate 18 move synchronously with the sliding ring 15. At this time, the second abutment plate 18 abuts against the teeth of the U-shaped rack 14, causing the U-shaped rack 14 to slide away from the first rotating handle 10 along the inner walls of the second clearance groove 7 and the third clearance groove 11 respectively. At the same time, the piston 13, driven by the U-shaped rack 14, slides away from the first rotating handle 10 along the inner wall of the insertion tube 9, pushing out the ointment in the insertion tube 9. The ointment is discharged from the inside of the insertion tube 3 under the push of the piston 13.

[0043] When ointment needs to be filled, the movable plate 19 can be activated. The sliding ring 15 will slide along the outer wall of the sliding part 2 towards the first rotating handle 10 under the action of the movable plate 19. The C-shaped elastic plate 17 and the second abutting plate 18 move synchronously until the outer wall of the C-shaped elastic plate 17 abuts against the open end of the first abutting plate 8. At this time, the C-shaped elastic plate 17 is bent and deformed under force, which drives the second abutting plate 18 to lift up and release the restriction on the U-shaped rack 14. After completing the above operation, the first rotating handle 10 is rotated counterclockwise to unscrew it from the threaded end of the handle 1. Then, the first rotating handle 10 is pulled to pull the insert 9 out of the handle 1, which is convenient for adding ointment to the insert 9. The above structure can not only push the movable plate 19 to drive the piston 13 to slide along the inner wall of the insert 9, thereby pushing out the ointment in the insert 9; it can also rotate the first rotating handle 10 to install the insert 9 into the handle 1 or pull it out from the handle 1. This installation and disassembly method is simple and convenient for filling ointment.

[0044] like Figures 1 to 8 As shown, the drug delivery assembly also includes a drug application head 20 sleeved on the cannula 3. The drug application head 20 has symmetrically formed snap-fit ​​grooves 22 on both outer walls near the end of the cannula 3. A fourth clearance groove 24 is formed on the outer wall of the end of the drug application head 20 away from the cannula 3. A drug application channel 21 is formed at the end of the drug application head 20 near the cannula 3, and the drug application channel 21 is connected to the fourth clearance groove 24 (e.g., ...). Figure 8 A medicine-applying ball 29 is rotatably installed on the inner wall of the fourth clearance groove 24. A first limiting post 25 is fixedly connected to the inner wall of one end of the fourth clearance groove 24. A clearance circular hole 26 is opened on the inner wall of the other end of the fourth clearance groove 24. The positions of the first limiting post 25 and the clearance circular hole 26 are symmetrical about the central axis of the fourth clearance groove 24. A C-shaped circular tube 27 is fixedly connected to the end of the medicine-applying head 20 away from the insertion tube 3. A second limiting post 28 is fixedly connected to the other end of the C-shaped circular tube 27.

[0045] Specifically, the application head 20 is fitted onto the outer wall of the cannula 3. The application head 20 is a Z-shaped plastic block. Two snap-fit ​​grooves 22 are symmetrically formed on the outer walls of the application head 20 near the end of the cannula 3. The snap-fit ​​grooves 22 are semi-circular grooves, and the outer contour of the snap-fit ​​protrusion 5 matches the inner contour of the snap-fit ​​groove 22. Therefore, when the application head 20 is aligned with the cannula 3, guided by the open ends of the two snap-fit ​​plates 4, the application head 20 can be fitted onto the outer wall of the cannula 3, and the snap-fit ​​protrusion 5 is embedded into the snap-fit ​​groove 22. Inside, the fourth clearance groove 24 is formed on the outer wall of the end of the application head 20 away from the insertion tube 3, and the fourth clearance groove 24 is a semi-circular groove. The application channel 21 is formed at the end of the application head 20 near the insertion tube 3 (i.e., the connection between the application head 20 and the insertion tube 3). The application channel 21 is a circular groove that extends through and through the interior of the application head 20, and the end of the application channel 21 away from the insertion tube 3 will emerge from the inner wall of the fourth clearance groove 24. Because the inner wall contour of the fourth clearance groove 24 is consistent with the application channel 24, the application channel 21 is formed by the fourth clearance groove 24 and the insertion tube 3. The outer contour of the ball 29 is adapted to the shape, so the medicated ball 29 can rotate on the inner wall of the fourth clearance groove 24. The medicated ball 29 is a metal sphere, and symmetrical circular grooves are formed on its outer wall. The metal medicated ball 29 has a low temperature and a smooth surface, which can reduce the pain of the patient's burn wound when rolling the medicated ball. The first limiting post 25 and the second limiting post 28 are both plastic cylinders with rounded corners at one end, while the clearance hole 26 is a circular groove, and the C-shaped tube 27 is... When the C-shaped plastic tube 27 is subjected to force, it will deform along its bending direction. Since the outer wall contour of the second limiting post 28 is adapted to the inner wall contour of the clearance hole 26, the second limiting post 28 can be inserted into the clearance hole 26. The outer wall contours of the first limiting post 25 and the second limiting post 28 are adapted to the two grooves on the outer wall of the coating ball 29, respectively. Therefore, the cooperation between the first limiting post 25 and the second limiting post 28 will rotate the coating ball 29 onto the inner wall of the fourth clearance groove 24.

[0046] When medical staff use this device to apply medication to a patient's wound, they first align the application head 20 with the cannula 3. Guided by the open ends of the two locking plates 4, the application head 20 can be fitted onto the outer wall of the cannula 3. Then, by pushing and pulling the movable plate 19, the ointment can be pushed out from inside the cannula 9. The ointment enters the application channel 21 through the cannula 3, and then exits from the end of the application channel 21 away from the cannula 3, adhering to the outer wall of the application ball 29. Medical staff gently touch the application ball 29 to the patient's wound and roll it, and the ointment on its outer wall can be applied to the wound. After the patient's wound is treated, the two locking plates 4 are opened. Release the locking and limiting position of the application head 20, and pull the application head 20 out of the outer wall of the insertion tube 3; then bend the C-shaped tube 27 to deform it along the bending direction, pull the second limiting post 28 out of the inner wall of the relief hole 26, and release the fixation of the application ball 29. Then the application ball 29 can be taken out from the inner wall of the fourth relief groove 24. The above structure not only reduces the patient's discomfort when applying ointment to the patient's wound, but also replenishes the ointment to the application ball 29 while applying the ointment; in addition, the application head 20 and the application ball 29 can be disassembled separately for subsequent cleaning of the device.

[0047] like Figures 1 to 9 As shown, a first clamping plate 23 is fixedly connected to one side of the outer wall of the application head 20. A first clamping rubber 33 is slidably connected to the outer wall of the first clamping plate 23 away from the application head 20. A second clamping plate 30 is slidably connected to the outer wall of the U-shaped rack 14 away from the piston 13. A second rotating handle 31 is screwed to one side of the outer wall of the second clamping plate 30. A second clamping rubber 32 is slidably connected to the outer wall of the second clamping plate 30 away from the second rotating handle 31.

[0048] Specifically, the first clamp 23 is fixedly connected to the outer wall of one side of the application head 20. The first clamp 23 is a square plastic plate, and the first clamping rubber 33 is slidably connected to the outer wall of the first clamp 23 away from the application head 20. Since the outer wall of the second clamp 30 has a groove that matches the outer contour of the U-shaped rack 14, the second clamp 30 can be slidably connected to the outer wall of the U-shaped rack 14 away from the piston 13. The second rotating handle 31 consists of two parts: a plastic cylinder with threads on its outer wall and a plastic cylinder with anti-slip grooves on its outer wall. The threaded end of the second rotating handle 31 will abut against the outer wall of the U-shaped rack 14 when the second rotating handle 31 rotates, thus fixing the second clamp 30. The second clamping rubber 32 is slidably connected to the outer wall of one side of the second clamp 30. Since both the outer walls of the second clamp 30 and the second clamping rubber 32 have anti-slip grooves, the tension at the wound site can be reduced by squeezing the skin of the wound.

[0049] After medical staff apply ointment to the patient's wound, they can slide the second clamp 30 along the outer wall of the U-shaped toothed rack 14, making the gap between the first clamp 23 and the second clamp 30 larger than the size of the patient's wound. Then, the second clamping rubber 32 and the first clamping rubber 33 are pressed against the skin around the patient's wound, and the second clamp 30 is slid along the outer wall of the U-shaped toothed rack 14 towards the first clamp 23. The second clamping rubber 32 will squeeze the skin at the patient's wound under the action of the second clamp 30. Then, the second rotating handle 31 is rotated clockwise, so that its threaded end abuts against the outer wall of the U-shaped toothed rack 14, thereby fixing the second clamp 30. This keeps the second clamping rubber 32 and the first clamping rubber 33 in a state of squeezing the skin at the patient's wound, allowing medical staff to apply a dressing to the wound. The above structural setup, after applying ointment, can reduce the tension of the skin at the patient's wound by squeezing it, so as to apply the dressing and promote the subsequent recovery of the patient's wound.

[0050] The working principle of the technical solution provided by this invention is as follows:

[0051] In use, first inject the ointment into the end of the insert 9 furthest from the first rotating handle 10. Then insert the insert 9 into the handle 1 furthest from the cannula 3, allowing the insert 9 to slide along the inner wall of the handle 1 until the end of the insert 9 furthest from the first rotating handle 10 touches the inner wall of the handle 1 closest to the cannula 3. Then rotate the first rotating handle 10 clockwise to screw it into the end of the handle 1 furthest from the cannula 3, thus completing the installation of the insert 9. Next, align the application head 20 with the cannula 3. Guided by the open ends of the two locking plates 4, the application head 20 can be fitted onto the outer wall of the cannula 3. Then, medical personnel manually apply ointment to the first rotating handle 10. When the movable plate 19 is activated, the sliding ring 15 slides along the outer wall of the sliding part 2 towards the first rotating handle 10 under the action of the movable plate 19. The C-shaped elastic plate 17 and the second abutting plate 18 move synchronously with the sliding ring 15. During this process, when the second abutting plate 18 slides, it will be subjected to force and deformed along its bending direction by the abutting action of the inclined surface of the U-shaped rack 14 teeth, until the second abutting plate 18 slides to the next interval of the U-shaped rack 14 teeth. Then, under the elastic action of the C-shaped elastic plate 17 itself, it recovers its deformation, causing the second abutting plate 18 to abut against the U-shaped rack 14 again. At the corresponding toothed intervals, the medical staff then pushes the movable plate 19, which causes the sliding ring 15 to slide along the outer wall of the sliding part 2 toward the insertion tube 3. The C-shaped elastic plate 17 and the second contact plate 18 move synchronously with the sliding ring 15. Since the end of the second contact plate 18 away from the C-shaped elastic plate abuts against the intervals corresponding to the teeth on the U-shaped rack 14, it causes the U-shaped rack 14 to slide along the inner walls of the second clearance groove 7 and the third clearance groove 11 away from the first rotating handle 10. At the same time, the piston 13, driven by the U-shaped rack 14, slides along the inner wall of the insertion tube 9 away from the first rotating handle 10, inserting the tube into the insertion tube. The ointment in the tube 9 is pushed out and discharged from the inside of the cannula 3 by the piston 13. The ointment enters the application channel 21 through the cannula 3 and is discharged from the end of the application channel 21 away from the cannula 3 and adheres to the outer wall of the application ball 29 (by repeating the above operation, the ointment can be continuously pushed out from the tube 9 to replenish the ointment on the outer wall of the application ball 29). When the medical staff gently touches the patient's wound with the application ball 29 and rolls it, the ointment on its outer wall can be applied to the wound. After the application is completed, the second clamp 30 can be slid along the outer wall of the U-shaped toothed rack 14 so that the distance between the first clamp 23 and the second clamp 30 is greater than the size of the patient's wound.The second clamping rubber 32 and the first clamping rubber 33 are then placed against the skin around the patient's wound. The second clamping plate 30 is slid along the outer wall of the U-shaped toothed rack 14 towards the first clamping plate 23. The second clamping rubber 32, driven by the second clamping plate 30, compresses the skin at the patient's wound. Then, the second rotating handle 31 is rotated clockwise, causing its threaded end to abut against the outer wall of the U-shaped toothed rack 14, thus fixing the second clamping plate 30. This maintains the compression of the skin at the patient's wound by the second clamping rubber 32 and the first clamping rubber 33, allowing medical personnel to apply a dressing to the wound.

[0052] If insufficient ointment is found when applying it, first rotate the second rotating handle 31 counterclockwise to release the fixation of the second clamp 30; then slide the second clamp 30 out along the outer wall of the U-shaped rack 14 to remove it. Next, snap the movable plate 19, and the sliding ring 15 will slide along the outer wall of the sliding part 2 towards the first rotating handle 10 under the drive of the movable plate 19. The C-shaped elastic plate 17 and the second abutting plate 18 move synchronously until the outer wall of the C-shaped elastic plate 17 abuts against the open end of the first abutting plate 8. At this time, the C-shaped elastic plate 17 is bent and deformed under force, which drives the second abutting plate 18 to lift up and release the restriction on the U-shaped rack 14. After completing the above operation, rotate the first rotating handle 10 counterclockwise to unscrew it from the threaded end of the handle 1; then pull the first rotating handle 10 to pull the insert 9 out of the handle 1, making it easy to fill the insert 9 with ointment.
