[0001] The invention relates to the technical field of medical care appliances, in particular to a sponge bandage for medical care that is anti-loosening and positioning. Background Art

[0002] In the field of modern medical care, wound treatment is a basic and critical link. Bandages are commonly used consumables for wound treatment, and their performance directly affects the wound healing effect and patient recovery experience. Sponge bandages are a more common nursing bandage. Compared with traditional bandages, they have good stretchability and breathability.

[0003] The prior art (publication number: CN221751129U, Chinese patent publication date: September 24, 2024) discloses an elastic bandage that is convenient for fixing the end, including an elastic bandage body, an adhesive strip symmetrically adhered to the lower surface of the elastic bandage body, a plurality of equidistant air holes formed on the surface of the adhesive strip, a protective patch adhered to the side of the adhesive strip away from the elastic bandage body, and adsorbent cotton adhered to the sides corresponding to the two adhesive strips, and the upper surface of the adsorbent cotton adheres to the lower surface of the elastic bandage body. When medical personnel bandage a patient, they can wrap the elastic bandage body around the patient's designated position and adhere and fix the elastic bandage body to the designated position through the adhesive strip. The adsorbent cotton can absorb moisture from the patient's designated position. At the same time, the adhesive strip can fix the end of the elastic bandage after use, thereby avoiding the elastic bandage body from becoming loose and causing waste. The prior art (publication number: CN213190561U, Chinese patent publication date: 2021-05-14) discloses a new type of elastic bandage, which includes an elastic bandage and a connecting structure. An applicator is adhered to the inner surface of the elastic bandage. The connecting structure includes an elastic connector with one end connected to one free end of the elastic bandage, and a clamping seat arranged at the other free end of the elastic bandage. A plurality of claws are constructed on the inner surface of the elastic connector, a clamping hole is provided on the clamping seat, and an elastic sheet extending out of the clamping seat is connected to the clamping hole. At least two clamping grooves are constructed on the outer surface of the elastic sheet. The connecting structure is configured so that when the free end of the elastic connector passes through the clamping hole, the clamping claws are clamped in the clamping grooves to form a closed connection of the elastic bandage. The new elastic bandage of the utility model, by constructing a clamping connection structure at both ends of the elastic bandage, allows the user to independently and reasonably adjust the stretching length of the elastic bandage, thereby enhancing the adaptability and tightening effect of the elastic bandage in different positions. Existing medical care bandages are mostly fixed by bonding or a single buckle during use. However, as the binding absorbs body fluids, its gravity will gradually increase. A single positioning method cannot ensure the stability of the binding during long-term use, and the bandage is prone to falling off, resulting in certain usage defects. Summary of the Invention

[0004] The purpose of the present invention is to provide a sponge bandage for medical care that is anti-loosening and positioned, so as to solve the problem raised in the above background technology that most of the sponge bandages for medical care on the market are bound and fixed by bonding or a single buckle during use. However, as the binding absorbs body fluids, its gravity will gradually increase.

[0006] Preferably, the body fluid adsorption part at the center of the bandage base is arranged in a circular structure, and when in use, the body fluid adsorption part is attached to the patient's wound to achieve body fluid adsorption, and the surface of the body fluid adsorption part protrudes from the surface of the bandage base.

[0007] Preferably, two adhesive layers are fixedly bonded to the top of the body fluid adsorption portion, and the adhesive layers are arranged in a ring structure, and when the bandage base is tied, the adhesive layers are sealed and adhered to the outside of the patient's body.

[0008] Preferably, the limiting plate is arranged in a Z-shaped structure, and the right end of the limiting plate is embedded and fixedly installed on the inner side of the bandage base, and during the binding process of the bandage base, the limiting plate passes through the positioning hole to achieve binding of the two ends of the bandage base.

[0009] Preferably, the adaptive negative pressure adsorption mechanism includes an annular groove body opened on the surface of the body fluid adsorption part, and an elastic diaphragm is fixedly installed in the annular groove body, and the elastic diaphragm is arranged in an annular structure. At the same time, the inner and outer circles of the elastic diaphragm are respectively sealed with the two adhesive layers. The elastic diaphragm forms a sealed space between the adhesive layer and the patient's body surface, and the lower surface of the adhesive layer and the edge position of the adsorption expansion part are fixedly connected with a traction mechanism for pulling the elastic diaphragm to deform, and the elastic diaphragm will be pulled by the traction mechanism during the process of liquid absorption and expansion of the adsorption expansion part.

[0010] Preferably, the traction mechanism includes a pull plate fixedly mounted on the lower surface of the elastic diaphragm, and the pull plate is arranged in an annular structure, and the lower surface of the pull plate is evenly and fixedly connected with a traction rope, and the lower end of the traction rope is fixedly connected to the edge position of the adsorption expansion member. During the expansion of the adsorption expansion member, the pull plate is pulled downward inside the annular groove body by the traction rope, and a negative pressure adsorption effect is generated between the annular groove body and the patient's body surface during the stretching of the elastic diaphragm.

[0011] Preferably, the airbag adjustment assembly includes an air supply tube symmetrically fixedly installed on the inner side of the bandage base, and the outer side of the air supply tube is evenly connected to the airbag tube, and one end of the air supply tube located on the outer side of the bandage base is fixedly connected to the air storage bag, and when the air storage bag is pressurized, the gas is transported to the airbag tube through the air supply tube.

[0012] Preferably, the airbag tube is embedded in the inner side of the bandage base, and after the airbag tube is inflated, it pushes the existing position of the bandage base to bulge, so as to increase the friction between the bandage base and the patient's body surface.

[0013] Preferably, the positioning hole is located between two adjacent airbag tubes, and the initial gap between the two adjacent airbag tubes is greater than the thickness of the limiting plate, and the outer wall of the limiting plate is evenly provided with anti-slip grooves, and the inflated airbag tube is partially embedded in the anti-slip groove to lock the limiting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the anti-slip positioning medical care sponge bandage can achieve fast and stable binding and locking, and can realize adaptive locking adjustment according to the absorption of body fluids, effectively ensuring the binding stability of the band body, and can realize the adjustment of the pressure position, avoiding the blood circulation problems caused by constant pressure at a single position, and reducing the discomfort caused by binding. The specific contents are as follows; 1. A limit plate and a positioning hole are provided. When the bandage base is tied outside the patient's body, the limit plate is passed through the positioning hole to lock and splice the two ends of the bandage base, effectively improving the connection stability between the two. 2. It is equipped with a body fluid adsorption part, an adsorption expansion part and an elastic diaphragm. The body fluid adsorption part and the adsorption expansion part can absorb the body fluid flowing out of the patient's wound. As the adsorption expansion part absorbs the body fluid, it will gradually expand. The expanded adsorption expansion part will move in the annular groove by pulling the pull plate through the traction rope. At this time, the pull plate will pull the elastic diaphragm to stretch and deform. The stretched elastic diaphragm will reduce the air pressure between it and the patient's body surface, so that the body fluid adsorption part fits outside the patient's body under the action of negative pressure, so that the bandage can achieve adaptive positioning adjustment according to the adsorption gravity of the body fluid, further ensuring the binding stability of the bandage; 3. An air storage bag and an air bag tube are provided. When the bandage is tied, one of the air storage bags is inserted between the band body and the body surface, thereby squeezing the air storage bag and allowing part of the gas in the air storage bag to enter the air bag tube through the air tube, causing the air bag tube to expand and making the surface of the bandage base uniformly convex, so as to improve the binding stability of the bandage. At the same time, the inflated air bag tube can cooperate with the anti-slip groove to improve the stability of the limiting plate and avoid the limiting plate from accidentally slipping off. Subsequently, another air storage bag is replaced for squeezing, which can make the other set of air bag tubes expand, realizing alternating adjustment of the pressure position, avoiding always applying pressure to the same position of the patient, and reducing discomfort during use.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: The existing sponge bandage is not convenient for locking the bandage in multiple ways, which makes it easy to slip after absorbing body fluids and gaining weight. In order to solve this technical problem, this embodiment discloses the following technical content, please refer to Figures 1-10 As shown; a sponge bandage for medical care with an anti-falling and positioning function, comprising a bandage base 1, and a body fluid adsorption portion 2 is provided on the upper surface of the central position of the bandage base 1; The lower surface of the right part of the bandage base 1 is evenly provided with a limiting plate 3 for binding and limiting, and a positioning hole 4 is provided on the left part of the bandage base 1, and an adsorption expansion part 5 is fixedly provided at the inner center position of the bandage base 1, and an adhesive layer 6 is bonded and fixed to the upper surface of the body fluid adsorption part 2, and a groove structure is also provided on the upper surface of the body fluid adsorption part 2, and an adaptive negative pressure adsorption mechanism for improving the stability of the band body is provided in the groove of the body fluid adsorption part 2.

[0019] The body fluid adsorption part 2 at the center of the bandage base 1 is arranged in a circular structure, and the body fluid adsorption part 2 is attached to the patient's wound when in use to achieve body fluid adsorption, and the surface of the body fluid adsorption part 2 protrudes from the surface of the bandage base 1, and two adhesive layers 6 are fixedly bonded to the top of the body fluid adsorption part 2, and the adhesive layer 6 is arranged in an annular structure, and when the bandage base 1 is tied, the adhesive layer 6 is sealed and adhered to the patient's body, the limiting plate 3 is arranged in a Z-shaped structure, and the right end of the limiting plate 3 is embedded in and fixedly installed on the inner side of the bandage base 1, and during the binding process of the bandage base 1, the limiting plate 3 passes through the positioning hole 4 to achieve binding of the two ends of the bandage base 1, the adaptive negative pressure adsorption mechanism includes an annular groove body opened on the surface of the body fluid adsorption part 2, and an elastic diaphragm 7 is fixedly installed in the annular groove body, and the elastic diaphragm 7 is arranged in an annular structure, and at the same time The inner and outer circles of the elastic diaphragm 7 are sealed and connected to the two adhesive layers 6 respectively. A sealed space is formed between the elastic diaphragm 7 and the patient's body surface through the adhesive layer 6, and the lower surface of the adhesive layer 6 and the edge position of the adsorption expansion part 5 are fixedly connected with a traction mechanism for pulling the elastic diaphragm 7 to deform, and the adsorption expansion part 5 will pull the elastic diaphragm 7 through the traction mechanism during the liquid absorption and expansion process. The traction mechanism includes a pull plate 8 fixedly mounted on the lower surface of the elastic diaphragm 7, and the pull plate 8 is arranged in an annular structure, and the lower surface of the pull plate 8 is evenly fixedly connected with a traction rope 9, and the lower end of the traction rope 9 is fixedly connected to the edge position of the adsorption expansion part 5. During the expansion process of the adsorption expansion part 5, the pull plate 8 is pulled downward inside the annular groove body by the traction rope 9. During the stretching of the elastic diaphragm 7, a negative pressure adsorption effect is generated between the annular groove body and the patient's body surface.

[0020] The body fluid adsorption part 2 is aligned with the patient's wound, and the adhesive layer 6 is attached to the outside of the body near the patient's wound, and the right end of the bandage base 1 is attached to the patient's body surface, and the left end of the bandage base 1 is wrapped around the patient's body, so that the bandage base 1 is tied to the patient's wound. After the tying is completed, the limiting plate 3 is passed through the positioning hole 4 at the corresponding position to realize the splicing and positioning of the two ends of the bandage base 1. The body fluid adsorption part 2 and the adsorption expansion part 5 can absorb the body fluid. When the adsorption expansion part 5 expands after absorbing the fluid, it pulls the pull plate 8 to slide in the annular groove through the traction rope 9. At this time, the pull plate 8 will pull the elastic diaphragm 7 for tensile deformation. After stretching, the air pressure between the elastic diaphragm 7 and the patient's body surface is reduced, so that the body fluid adsorption part 2 can improve the adhesion stability through the negative pressure effect, thereby avoiding slipping after the belt body absorbs fluid and gains weight.

[0021] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. After the medical care sponge bandage is tied, it is inconvenient to adjust the binding pressure, and the binding pressure position is fixed, which easily leads to poor blood circulation at the pressure point. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 4-Figure 6 and Figure 11 As shown; the inner side of the bandage base 1 is also provided with an airbag adjustment component for adjusting the tightness of the binding, the airbag adjustment component includes an air supply tube 10 symmetrically fixedly installed on the inner side of the bandage base 1, and the outer side of the air supply tube 10 is evenly connected to the airbag tube 12, and one end of the air supply tube 10 located on the outer side of the bandage base 1 is fixedly connected to the air storage bag 11, and at the same time, after the air storage bag 11 is pressurized, the gas is transported to the airbag tube 12 through the air supply tube 10, and the airbag tube 12 is embedded and installed on the inner side of the bandage base 1, and after the airbag tube 12 is inflated, it pushes the existing position of the bandage base 1 to bulge, so as to increase the friction between the bandage base 1 and the patient's body surface, the positioning hole 4 is located between two adjacent airbag tubes 12, and the initial gap between the two adjacent airbag tubes 12 is greater than the thickness of the limiting plate 3, and the outer wall of the limiting plate 3 is evenly provided with anti-slip grooves 301, and at the same time, the inflated airbag tube 12 is partially embedded in the anti-slip groove 301 to achieve locking of the limiting plate 3.

[0022] When the bandage base 1 is tied, one of the air bags 11 is inserted between the bandage base 1 and the body surface, so that the air bag 11 is pressurized. At this time, part of the gas in the air bag 11 will enter the air bag tube 12 connected to its outside through the air supply tube 10, causing the air bag tube 12 to expand to a certain extent. The expanded air bag tube 12 will push the corresponding position of the surface of the bandage base 1 to bulge, thereby improving the binding tightness of the bandage base 1. By adjusting the degree of insertion and squeezing of the air bag 11, the binding tightness can be conveniently adjusted. At the same time, the inflated air bag tube 12 will be stuck in the anti-slip groove 301 in the existing position, thereby achieving auxiliary locking of the limit plate 3, further improving the binding stability of the belt body, and subsequently by replacing the air bag 11 for squeezing, the two groups of air bag tubes 12 can alternately apply pressure to different positions of the patient's body surface, avoiding the same position being always pressurized and causing discomfort.
