Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a pressure ulcer relief bag with binding and restraint function. Background Technology

[0002] Pressure injuries (also known as pressure ulcers) are one of the most common complications of prolonged bed rest in elderly, frail, critically ill, and mobility-limited patients. Prolonged bed rest can easily cause damage to the body's structure, which not only increases the patient's physical and psychological suffering, but also greatly reduces the patient's quality of life, prolongs the recovery time, and in severe cases, even endangers the patient's life.

[0003] In clinical practice, to prevent pressure injuries to local skin areas such as the sacrum, coccyx, and heels of bedridden patients, and for cost-saving and flexible use, simple decompression water bags are often made from the intravenous nutrition bags after the intravenous nutrition solution has been infused. These bags are placed on the patient's sacrum, coccyx, occipital region, or heels to relieve pressure. However, in clinical use, it has been found that these decompression water bags are prone to displacement and cannot properly support the affected area, causing inconvenience.

[0004] To overcome the aforementioned deficiencies, existing patented technologies, such as Chinese Utility Model Patent, Authorization Announcement No.: CN212016011U, disclose an internally hollow decompression water bag, including a decompression bag body. The decompression bag body is generally annular, with a hollow center, and the cross-section of the annular decompression bag body is circular. An anti-slip plate is provided at the bottom end of the decompression bag body, and the anti-slip plate is also annular. The bottom end of the anti-slip plate is flat, with multiple anti-slip protrusions on the flat surface, which effectively prevents the decompression bag body from moving and deforming at the bottom during use. Simultaneously, multiple cushioning mechanisms are provided inside the decompression water bag. During use, the first and second cushioning springs are compressed, preventing collision between the connecting sleeves and providing overall cushioning. The two springs provide good cushioning, effectively protecting the patient's body and providing comfort.

[0005] While the aforementioned existing patented technical solutions avoid displacement and provide a buffering effect, they also introduce new technical problems:

[0006] In general, the pressure relief bag is circular in shape with a hollow center. This reduces the contact area of ​​the affected area when it is compressed, thus increasing the pressure on the affected area and exacerbating pressure injuries. For patients, compared to a block-shaped pressure relief bag, the circular shape makes it more difficult to position the bag efficiently and conveniently on the affected area. Furthermore, the pressure relief bag does not have a restraint function, making it difficult to restrain the bag and prone to displacement.

[0007] In view of the above, a pressure ulcer relief bag with binding constraint function is proposed to solve the above problems. Utility Model Content

[0008] To address the problems existing in the prior art, this utility model provides a pressure ulcer pressure relief bag with binding and restraint function. When using this pressure ulcer pressure relief bag, on the one hand, the structural orientation design of the two rough positioning parts and the cold gel layer allows for efficient positioning of the affected area. Because the material of the cold gel layer is relatively soft, the affected area can sink into the surface of the cold gel layer when subjected to pressure and cushioning, increasing the contact area of ​​the affected area and reducing the pressure on the affected area. Utilizing the static friction of the cold gel layer, the patient's affected area can be confined to the cold gel layer, which to a certain extent avoids the problem of the affected area shifting.

[0009] On the other hand, the first restraint strap and the second restraint strap can be connected by crossing and tightening in a diagonal direction, or they can be connected by wrapping and overlapping, so that the decompression bag body can be bound and fixed to the patient's affected area through the first restraint strap and the second restraint strap, achieving binding and binding in a diagonal or non-diagonal direction, further avoiding the problem of displacement of the affected area, and helping to restrain the decompression bag body and the affected area.

[0010] In addition, when the peripheral dimensions of the affected area are small and the length of the restraint strap is large, in order to better bind the affected area to the decompression bag body, the first restraint strap and the second restraint strap can be wrapped around multiple times until the length of the restraint strap is appropriate, so that the affected area can be bound to the decompression bag body, which is more convenient for clinical use.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0012] This application proposes a pressure ulcer relief bag with binding and restraint function, including a pressure ulcer bag body. One end of the pressure ulcer bag body is provided with an injection port and a discharge port. Two rough positioning parts are symmetrically arranged on one side surface of the pressure ulcer bag body. A cold gel layer is laid between the two rough positioning parts. Along the length direction of the pressure ulcer bag body, at least two sets of connecting buckles are symmetrically arranged on both sides of the pressure ulcer bag body. Each set of connecting buckles is connected to a first restraint strap and a second restraint strap. The first restraint strap and the second restraint strap can be cross-tightly connected in a diagonal direction, and / or the first restraint strap and the second restraint strap can be wrapped around and overlapped for tight connection. Both the first restraint strap and the second restraint strap have elasticity.

[0013] To solve its technical problem, the further technical solution adopted by this utility model is as follows:

[0014] Optionally, in the pressure ulcer relief bag described above, the two rough positioning parts are bonded to the surface of the pressure relief bag body by an adhesive layer, and the surfaces of the two rough positioning parts are designed with a rough structure, wherein the rough structure is: the surfaces of the two rough positioning parts are covered with a number of friction bumps.

[0015] Optionally, in the pressure ulcer relief bag described above, the cold gel layer is bonded to the surface of the pressure relief bag body by an adhesive layer, and a release layer is provided on the side of the cold gel layer away from the pressure relief bag body.

[0016] Optionally, in the pressure ulcer relief bag described above, the ends of the first and second restraint straps are each connected to a connector. The connector includes a Velcro fastener, an abutment block, and a slot formed on the abutment block. The male and female Velcro fasteners are respectively disposed on the two side surfaces of the abutment block, and the male and female Velcro fasteners are respectively located on both sides of the slot. The connectors on the first and second restraint straps can be interlocked and bonded to each other.

[0017] Further optionally, in the aforementioned pressure ulcer relief bag, when the connectors on the first restraint strap and the connectors on the second restraint strap can be interlocked, the two connectors are interlocked by their respective slots and abutment blocks, and simultaneously, the two connectors are interlocked by their respective Velcro fasteners.

[0018] Alternatively, in the aforementioned pressure ulcer relief bag, the opening direction of the slot on the connector of the first restraint strap is opposite to the opening direction of the slot on the connector of the second restraint strap.

[0019] Optionally, in the pressure ulcer relief bag described above, the bag body is filled with a transparent liquid or liquid silicone.

[0020] Optionally, in the pressure ulcer relief bag described above, the connecting buckle is integrally formed with the body of the pressure relief bag, and the corners of the connecting buckle are designed with a rounded arc shape.

[0021] Further optionally, in the above-mentioned pressure ulcer relief bag, the first restraint strap, the second restraint strap, and the connecting buckle are connected by a movable connection; the first restraint strap and the second restraint strap are flat elastic bands.

[0022] Optionally, in the pressure ulcer relief bag described above, the bag body and the connecting buckle are both made of nylon or polyethylene; the rough positioning part and the friction protrusions are both made of rubber.

[0023] Compared with the prior art, this application has the following technical effects:

[0024] On the one hand, two rough positioning parts are symmetrically arranged on one side surface of the pressure relief bag body of this application, and a cold gel layer is laid between the two rough positioning parts. Through the structural orientation design of the two rough positioning parts and the cold gel layer, the affected area can be efficiently positioned. Since the material of the cold gel layer is relatively soft, the affected area can sink into the surface of the cold gel layer when it is subjected to pressure and cushioning, increasing the contact area of ​​the affected area and reducing the pressure on the affected area. By utilizing the static friction of the cold gel layer, the patient's affected area can be confined to the cold gel layer, which to a certain extent avoids the problem of the affected area shifting.

[0025] On the other hand, along the length of the decompression bag body, two sets of connecting buckles are symmetrically arranged on both sides of the decompression bag body. Each set of connecting buckles is connected to a first restraint strap and a second restraint strap. The first restraint strap and the second restraint strap can be connected by crossing and tightening in a diagonal direction, or they can be connected by wrapping and overlapping. This allows the decompression bag body to be bound and fixed to the patient's affected area through the first restraint strap and the second restraint strap, achieving binding and binding in a diagonal or non-diagonal direction, further preventing the affected area from shifting, and helping to restrain the decompression bag body and the affected area.

[0026] In addition, both the first and second restraint straps of this application are elastic. When the peripheral dimensions of the affected area are small and the length of the restraint straps is large, in order to better bind the affected area and the decompression bag body, the first and second restraint straps can be wrapped around multiple times until the length of the restraint straps is appropriate, thus binding and restraining the affected area and the decompression bag body. This is more convenient for clinical use.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Example 1

[0037] like Figures 1 to 3 As shown, in one embodiment of this application, a pressure ulcer relief bag with binding and restraint function is proposed, including a pressure ulcer relief bag body 1. One end of the pressure ulcer relief bag body 1 is provided with an injection port 11 and a discharge port 12. Two rough positioning parts 13 are symmetrically arranged on one side surface of the pressure ulcer relief bag body 1. A cold gel layer 14 is laid between the two rough positioning parts 13. Along the length direction of the pressure ulcer relief bag body 1, at least two sets of connecting buckles 2 are symmetrically arranged on both sides of the pressure ulcer relief bag body 1. Each set of connecting buckles 2 is connected to a first restraint band 3 and a second restraint band 4. The first restraint band 3 and the second restraint band 4 can be cross-tightly connected in a diagonal direction, and / or the first restraint band 3 and the second restraint band 4 can be wrapped around and overlapped for tight connection. Both the first restraint band 3 and the second restraint band 4 have elasticity.

[0038] In this embodiment, on one hand, two rough positioning parts are symmetrically arranged on one side surface of the pressure relief bag body, and a cold gel layer is laid between the two rough positioning parts. Through the structural orientation design of the two rough positioning parts and the cold gel layer, the affected area can be efficiently positioned. Since the material of the cold gel layer is relatively soft, the affected area can sink into the surface of the cold gel layer when it is subjected to pressure and cushioning, increasing the contact area of ​​the affected area and reducing the pressure on the affected area. By utilizing the static friction of the cold gel layer, the patient's affected area can be confined to the cold gel layer, which to a certain extent avoids the problem of the affected area shifting.

[0039] In this embodiment, on the other hand, along the length of the decompression bag body, two sets of connecting buckles are symmetrically arranged on both sides of the decompression bag body. Each set of connecting buckles is connected to a first constraint strap and a second constraint strap. The first constraint strap and the second constraint strap can be connected by crossing and tightening in a diagonal direction, or they can be connected by wrapping and overlapping to tighten them. This allows the decompression bag body to be bound and fixed to the patient's affected area through the first constraint strap and the second constraint strap, achieving binding and binding in a diagonal or non-diagonal direction, further preventing the affected area from shifting, and helping to constrain the decompression bag body and the affected area.

[0040] In this embodiment, both the first and second restraint straps are elastic. When the outer periphery of the affected area is small and the length of the restraint straps is large, in order to better bind the affected area to the decompression bag body, the first and second restraint straps can be wrapped around multiple times until the length of the restraint straps is appropriate, thus binding the affected area to the decompression bag body. This is more convenient for clinical use.

[0041] In another embodiment of this application, such as Figures 1 to 3 As shown, optionally, the two rough positioning parts 13 are bonded to the surface of the pressure relief bag body 1 by an adhesive layer (not shown). The surfaces of the two rough positioning parts 13 are designed to have a rough structure, wherein the rough structure is: the surfaces of the two rough positioning parts 13 are covered with a plurality of friction bumps 131.

[0042] In this embodiment, by designing several friction protrusions on the surface of the rough positioning part, frictional resistance can be generated on the affected area, preventing large displacement between the affected area and the pressure relief bag body.

[0043] In another embodiment of this application, such as Figure 1 As shown, optionally, the cryogel layer 14 is bonded to the surface of the decompression bag body 1 by an adhesive layer, and a release layer 15 is provided on the side of the cryogel layer 14 away from the decompression bag body 1.

[0044] In this embodiment, a release layer is provided on the cold gel layer, which can clean and protect the surface of the cold gel layer from dust and ensure good adhesion of the surface of the cold gel layer.

[0045] In another embodiment of this application, such as Figure 1 , Figure 4 and Figure 5As shown, optionally, the ends of the first constraint band 3 and the second constraint band 4 are each connected to a connector 5. The connector 5 includes a nylon hook and loop fastener 51, an abutment block 52, and a slot 53 formed on the abutment block 52. The male hook and loop fastener 511 and the female hook and loop fastener 512 of the nylon hook and loop fastener 51 are respectively disposed on the two side surfaces of the abutment block 52. The male hook and the female hook and loop fastener are respectively located on the two side surfaces of the slot 53. The connector 5 on the first constraint band 3 and the connector 5 on the second constraint band 4 can be interlocked and bonded to each other.

[0046] In this embodiment, when the first restraint strap and the second restraint strap are interlocked and bonded together through the connectors, the two connectors are engaged with each other through their slots and abutment blocks. At the same time, the two connectors are bonded together through their Velcro fasteners and abutment blocks. This enhances the tensile strength and adhesive strength between the first restraint strap and the second restraint strap, making it easier to form a relatively stable structural bond with the patient's affected area and preventing the bond from loosening or shifting.

[0047] In another embodiment of this application, such as Figure 4 and Figure 5 As shown, optionally, when the connector 5 on the first constraint band 3 and the connector 5 on the second constraint band 4 can be interlocked and bonded to each other, the two connectors 5 are interlocked by their respective slots 53 and abutment blocks 52, and at the same time, the two connectors 5 are bonded to each other by their respective Velcro fasteners 51.

[0048] In this embodiment, the first constraint band and the second constraint band are interlocked by a slot and an abutment block. At the same time, in order to avoid separation between the first constraint band and the second constraint band to the greatest extent, a connector and its Velcro fastener are used to further enhance the adhesion between the first constraint band and the second constraint band.

[0049] In another embodiment of this application, such as Figure 1 and Figure 4 As shown, optionally, the opening direction of the slot 53 of the connector 5 on the first constraint band 3 is opposite to the opening direction of the slot 53 of the connector 5 on the second constraint band 4.

[0050] In this embodiment, whether the constraint bands are connected diagonally or in opposite directions, their respective slot opening directions are set in opposite directions, which facilitates the connection between the constraint bands.

[0051] In another embodiment of this application, such as Figure 3 As shown, optionally, the pressure-reducing bag body 1 is filled with a transparent liquid or liquid silicone.

[0052] In this embodiment, the pressure relief bag body 1 is filled with transparent liquid or liquid silicone, which can provide a good pressure relief and cushioning effect on the affected area.

[0053] In another embodiment of this application, such as Figure 1 and Figure 3 As shown, optionally, the connecting buckle 2 is integrally formed with the pressure-reducing bag body 1, and the corners of the connecting buckle 2 are designed with a rounded arc structure.

[0054] In this embodiment, the buckle and the pressure relief bag body are integrally molded, which helps to enhance the tensile strength between the buckle and the pressure relief bag body and prevent the buckle from breaking due to pulling. The corners of the buckle are designed with a rounded structure to avoid sharp scratches between the affected area and the buckle, thus preventing secondary injury to the patient's affected area.

[0055] In another embodiment of this application, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, optionally, the first constraint band 3, the second constraint band 4, and the connecting buckle 2 are connected by a movable connection; the first constraint band 3 and the second constraint band 4 are flat elastic bands.

[0056] In this embodiment, the restraint strap and the connecting buckle adopt a movable connection scheme, which makes assembly and disassembly more convenient. The restraint strap is a flat elastic band, which does not constrict the affected area and improves comfort.

[0057] In another embodiment of this application, such as Figures 1 to 3 As shown, optionally, the pressure relief bag body 1 and the connecting buckle 2 are both made of nylon or polyethylene; the rough positioning part 13 and the friction protrusion 131 are both made of rubber.

[0058] In this embodiment, the pressure relief bag body and the connecting buckle are both made of nylon or polyethylene, which have high tensile and tear strength, can withstand greater external forces, are lightweight and friction-resistant, and the rough positioning part and friction protrusions are made of rubber, which is soft and more friendly when in contact with the affected area, and does not harm the patient.

[0059] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
