Abstract
Description
Technical Field
[0001] This utility model relates to the field of wound dressing technology, specifically to a mother-and-child pressure dressing device for local facial wounds. Background Technology
[0002] Currently, when applying pressure bandages to head and facial wounds in oral and maxillofacial surgery patients, most methods use a full-face bandage with gauze placed inside for pressure application. This method has the following drawbacks:
[0003] 1. After placing gauze inside the bandage, the position of the gauze cannot be seen with the naked eye when bandaging because the gauze is on the inside. The gauze may deviate from the wound, resulting in low accuracy.
[0004] 2. When it is necessary to adjust the bandage pressure, the entire head bandage needs to be reopened, and adjusting the local pressure is cumbersome and inconvenient.
[0005] 3. The overall bandage on the head and face affects the patient's overall oral and facial movements, causing discomfort, affecting speech, eating, and oral hygiene. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model specifically provides a mother-daughter type pressure bandaging device for local facial wounds, including a daughter base plate and a mother base plate. The two sides of the daughter base plate and the mother base plate are respectively the facial skin surface and the tension band attachment surface. The facial skin surface is provided with adhesive that can be fixedly attached to the patient's face. Multiple daughter tension bands and multiple mother tension bands are fixedly provided on the tension band attachment surfaces of the daughter base plate and the mother base plate, respectively.
[0007] Each of the sub-tension bands can be connected to the corresponding mother tension band and its tension can be adjusted independently to press and fix the dressing placed between the two tension bands and the skin at the wound position and ensure that the local pressure is within the preset pressure range;
[0008] The sub-base plate can be cut along the extension direction of the sub-tension band, and the mother base plate can be cut along the extension direction of the mother tension band, so that the size of the sub-base plate and the mother base plate, as well as the number of the sub-tension band and the mother tension band, match the size of the wound, thereby achieving precise local pressure bandaging.
[0009] In a preferred embodiment of this utility model, the sub-tension band is configured as a hook and loop fastener, and the lateral tension band is configured as a loop fastener. The hook and loop fastener can be attached to the loop fastener at any position to fix the dressing and adjust its tightness.
[0010] In a preferred embodiment of this utility model, the sub-tension band is a cable tie bar, and the end of the female tension band is provided with a cable tie buckle. The cable tie bar can pass through the cable tie buckle and tighten to fix the dressing and adjust the tightness.
[0011] As a preferred embodiment of this utility model, the sub-tension band is made of a shearable material.
[0012] In a preferred embodiment of this invention, the dressing is gauze.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This invention utilizes a combination of a sub-base plate, a main base plate, sub-tension bands, and a main tension band. The base plate and tension bands can be cut to fit the size of the patient's wound, ensuring the size of the base plate and the number of tension bands match the wound size. The tension bands do not obstruct the dressing, facilitating the determination of the dressing's relative position to the wound and achieving precise local pressure bandaging. The area covered on the patient's face is smaller, minimizing impact on oral and facial movements. The tightness of each sub-tension band and its connection to the corresponding main tension band can be independently adjusted, ensuring even pressure on the wound. Furthermore, when pressure adjustment is needed, the tightness of the sub-tension band and its connection to the corresponding main tension band can be directly adjusted without needing to reopen the entire head bandage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] This utility model specifically provides a mother-daughter type pressure bandaging device for local facial wounds, including a daughter base plate 1 and a mother base plate 2. The two sides of the daughter base plate 1 and the mother base plate 2 are respectively a facial skin surface 1201 and a tension band attachment surface 1202. The facial skin surface 1201 is provided with adhesive that can be fixedly attached to the patient's face. Multiple daughter tension bands 3 and multiple mother tension bands 4 are fixedly provided on the tension band attachment surfaces 1202 of the daughter base plate 1 and the mother base plate 2, respectively. It can be understood that the aforementioned daughter tension bands 3 and mother tension bands 4 can be fixed to the daughter base plate 1 and the mother base plate 2 by adhesive bonding.
[0022] Each sub-tension band 3 can be connected to the corresponding female tension band 4 and its tension can be adjusted independently to press and fix the dressing placed between the two tension bands and the skin at the wound position and ensure that the local pressure is within the preset pressure range;
[0023] The sub-base plate 1 can be cut along the extension direction of the sub-tension band 3, and the mother base plate 2 can be cut along the extension direction of the mother tension band 4, so that the size of the sub-base plate 1 and the mother base plate 2, as well as the number of sub-tension bands 3 and mother tension bands 4, match the size of the wound, thereby achieving precise local pressure bandaging.
[0024] The method for applying pressure dressing to a patient's facial wound using the aforementioned mother-daughter type pressure dressing device is as follows:
[0025] First, based on the size of the patient's wound, the sub-base plate 1 and sub-tension band 3 are cut along the extension direction of the sub-tension band 3, and the mother base plate 2 and mother tension band 4 are cut along the extension direction of the mother tension band 4. This ensures that the size of the sub-base plate 1 and mother base plate 2, and the number of sub-tension bands 3 and mother tension bands 4, match the wound size. For larger wounds, the areas of the sub-base plate 1 and mother base plate 2 are larger, and the number of sub-tension bands 3 and mother tension bands 4 is greater; for smaller wounds, the areas of the sub-base plate 1 and mother base plate 2 are smaller, and the number of sub-tension bands 3 and mother tension bands 4 is less.
[0026] For example, both the sub-base plate 1 and the mother base plate 2 are 5×5cm. Five sub-tension bands 3 are evenly spaced on the sub-base plate 1, and five mother tension bands 4 are evenly spaced on the mother base plate 2. If the length of the wound is 2.5cm, the sub-base plate 1 and the mother base plate 2 can be cut to retain a size of 3×5cm, retaining three sub-tension bands 3 and three mother tension bands 4. The 3cm long dressing is then fixed and pressed tightly onto the wound. The tension bands will not obstruct the dressing, making it easy to determine the relative position of the dressing and the wound, and achieving precise local pressure bandaging.
[0027] After cutting, first peel off the backing of the sub-base plate 1 and the mother base plate 2, and fix the sub-base plate 1 and the mother base plate 2 to the appropriate positions on both sides of the patient's wound with adhesive. Then connect the sub-tension band 3 to the mother tension band 4 to fix the dressing to the wound. The tightness of each sub-tension band 3 and its connection to the corresponding mother tension band 4 can be adjusted independently to ensure that the local pressure of each point of the dressing is within the preset pressure range, so that the pressure of the dressing on the wound is uniform. When it is necessary to adjust the pressure, the tightness of the sub-tension band 3 and its connection to the corresponding mother tension band 4 can be adjusted directly without having to reopen the entire head bandage.
[0028] The dressing is secured to the wound by using two base plates and two tension straps, which minimizes the area covered on the patient's face and reduces the impact on the patient's oral and facial movements.
[0029] In summary, this invention, through the coordinated use of the sub-base plate 1, the mother base plate 2, the sub-tension band 3, and the mother tension band 4, allows for the cutting of the base plate and tension bands according to the size of the patient's wound. This ensures that the size of the base plate and the number of tension bands match the wound size, and the tension bands do not obstruct the dressing, facilitating the determination of the relative position of the dressing and the wound. This enables precise local pressure bandaging, with a smaller coverage area on the patient's face, minimizing the impact on the patient's oral and facial movements. The tightness of each sub-tension band 3 and its connection to the corresponding mother tension band 4 can be independently adjusted, ensuring uniform pressure on the wound. Furthermore, when pressure adjustment is needed, the tightness of the sub-tension band 3 and its connection to the corresponding mother tension band 4 can be directly adjusted without having to reopen the entire head bandage.
[0030] Furthermore, the sub-tension band 3 is configured as a hook-and-loop fastener 301, and the female tension band 4 is configured as a loop fastener 401. Specifically, the side of the sub-tension band 3 facing the patient's skin is the hook side, and the side of the female tension band 4 facing away from the patient's skin is the loop side. The hook-and-loop fastener 301 can adhere to the loop fastener 401 at any position to secure the dressing. The tension of the tension band can be adjusted by changing the adhesion position between the hook-and-loop fastener 301 and the loop fastener 401.
[0031] Alternatively, the sub-tension band 3 can be a cable tie bar 302, and the end of the female tension band 4 can be provided with a cable tie buckle 402. The cable tie bar 302 is existing technology, commonly used for binding, and can only be tightened in one direction. The cable tie bar 302 can pass through the cable tie buckle 402 and tighten to secure the dressing. By pulling the cable tie bar 302, the pressure on the dressing and wound can be gradually increased.
[0032] The attached diagram shows that the skin surface 1201 of the sub-base plate 1 and the tension band attachment surface 1202 of the mother base plate face the same side only to show the hook and loop fastener 301 and the cable tie bar 302. In actual use, the skin surface 1201 of the sub-base plate 1 and the skin surface 1201 of the mother base plate face the same side.
[0033] Furthermore, the sub-tension band 3 is made of a shearable material, so that after the dressing is fixed and tightened by the tension band, the excess sub-tension band 3 can be cut off.
[0034] Optionally, the dressing is gauze.
[0035] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
