Description

Technical Field

[0001] The utility model relates to the technical field of medical dressings, in particular to a puncture wound dressing. Background Art

[0002] Dressings are wound dressings, materials used to cover sores, wounds or other damage. In medical treatment, in order to ensure the stability of the drainage tube during drainage, it is often necessary to use the adhesive ability of the dressing to tie the drainage tube to the skin.

[0003] When the dressing is tied to the drainage tube, the dressing will deform accordingly with human activities. In the prior art, the ordinary dressing commonly used in medical treatment has only a thin layer of sponge pad. After being attached to the skin, as the human body moves, the attached part will be soaked and seeped due to skin movement. The liquid drained from the puncture port will affect the stickiness of the dressing after it seeps out, so that the dressing is easy to fall off, thereby causing the built-in drainage tube to fall off.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The puncture wound dressing reduces the contact area between the patch and the skin by setting the patch in a circular shape, thereby reducing the stimulation to a large area of ​​the skin during dressing, and then setting a pressure mechanism to press down the puncture wound, so that after the patch is attached, the center can exert an external pressure on the puncture wound, thereby preventing the skin from being soaked and exuded due to movement, and improving the stability of the drainage tube when in use.

[0016] 2. The puncture wound dressing is provided with a layer of compression patch on the dressing sheet. When exudation occurs at the puncture wound, the compression patch can be opened and the sponge pad can be replaced without affecting the puncture of the drainage tube, so as to avoid the exudate contacting the dressing sheet and causing the need for replacement. The fit between patches is more reusable than the fit between patches and skin. Therefore, the adhesion between the compression patch and the dressing sheet improves the convenience and sustainability of the dressing. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-6 The puncture wound dressing comprises: a dressing sheet 1, a pressing sheet 2 and a pressing mechanism 3;

[0026] The patch 1 is arranged in a circular shape, and the side of the pressing patch 2 close to the outer edge is integrally arranged on the patch 1, a sponge pad 4 is arranged at the center of the patch 1, the position of the pressurizing mechanism 3 corresponds to the position of the sponge pad 4, and the pressurizing mechanism 3 is arranged at the center of the pressing patch 2, and the sponge pad 4 is pressed on the puncture port.

[0027] Among them, the patch 1 includes an adhesive sheet 11, the bottom of the adhesive sheet 11 is the adhesive surface, a limiting sheet 12 is integrally arranged in the middle of the adhesive sheet 11, the sponge pad 4 is located below the limiting sheet 12, and a cross-shaped material replacement port 13 is opened on the surface of the limiting sheet 12. The cross-shaped material replacement port 13 is opened on the limiting sheet 12 in contact with the sponge pad 4, so that when exudation occurs at the puncture port, the pressure patch 2 can be opened to replace the sponge pad 4 without affecting the puncture of the drainage tube.

[0028] Among them, the pressing sheet 2 and the isolation film 5 are both made of transparent materials. After using the dressing, the condition of the sponge pad 4 can be observed through the pressing sheet 2 and the isolation film 5. If the sponge pad 4 changes color, the sponge pad 4 should be replaced immediately.

[0029] Among them, an isolation membrane 5 is arranged at the center of the bottom of the pressing sheet 2, and the outer edge of the isolation membrane 5 is sealed and bonded to the pressing sheet 2. The pressurizing mechanism 3 is located directly above the isolation membrane 5. The isolation membrane 5 is used to isolate the pressurizing mechanism 3 to prevent bacteria from entering the pressing sheet 2 through the gap when the pressurizing mechanism 3 is in operation.

[0030] Among them, the pressing sheet 2 includes a tape sheet 21, a connecting sheet 22 is arranged at the outer edge of the tape sheet 21, the connecting sheet 22 is arranged on the patch 1, and a load-bearing sheet 23 is integrally arranged at the center of the tape sheet 21. The pressure-applying mechanism 3 is installed in the middle of the load-bearing sheet 23. The pressing sheet 2 is integrally arranged on the patch 1 by using the connecting sheet 22, so that the pressing sheet 2 will not fall off the patch 1 easily, and the load-bearing sheet 23 is arranged to reduce the elastic ability of the pressing sheet 2 when it is subjected to force, so that the pressure-applying mechanism 3 can have sufficient pushing force when it is running.

[0031] Among them, the pressurizing mechanism 3 includes a mounting ring 31, the outer edge of which is provided with a sealing groove 32, the inner wall of the sealing groove 32 is sealed and connected to the pressing patch 2, the inside of the mounting ring 31 is slidably connected with a guide piece 33, the bottom of the guide piece 33 is connected with a rubber plug block 34, the rubber plug block 34 is pressed on the puncture port, the inside of the guide piece 33 is threaded with a screw rod 35, the top of the screw rod 35 passes through the mounting ring 31 and is provided with a rotary handle 36, and the pressurizing mechanism 3 is provided to press down the puncture port, so that after the patch 1 is attached, an external pressure can be applied to the puncture port at the center to prevent the skin from being soaked and seeping due to movement.

[0032] Among them, a limit plate 37 is sleeved on the surface of the screw rod 35 near the top, and the limit plate 37 is located inside the mounting ring 31. The inner diameter of the mounting ring 31 where the screw rod 35 penetrates is smaller than the diameter of the limit plate 37. By setting the limit plate 37, the screw rod 35 is restricted inside the mounting ring 31, so that no matter how the screw rod 35 rotates, the handle 36 is always on the surface of the mounting ring 31 and will not fall off.

[0033] Among them, the surface of the guide piece 33 is hexagonal, and the shape of the inner wall of the mounting ring 31 is adapted to the shape of the surface of the guide piece 33. The hexagonal shape is used to limit the guide piece 33, so that when the screw 35 rotates, the guide piece 33 can only rise or fall, and will not rotate with the screw 35.

[0034] Working principle: when using the dressing to fit the puncture hole, first press the drainage tube onto the skin through the patch 1 so that the puncture hole is located in the middle of the patch 1, then fill the sponge pad 4 on the puncture hole through the middle of the patch 1, and then turn the pressing patch 2 over and press it on the sponge pad 4. After the patch is firmly attached, control the pressure mechanism 3 to apply pressure downward to press the sponge pad 4 tightly against the puncture hole to avoid the exudate destroying the adhesion of the patch 1.
