Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to compression hemostatic patch. BACKGROUND

[0002] In the medical field, for wound treatment after trauma and surgery, hemostasis is a crucial step. Effective hemostasis not only reduces blood loss but also prevents infection and promotes wound healing. The widely used hemostatic patches on the market are mainly composed of water-absorbing pads and adhesive backing, which can provide basic protection to prevent external pollution from entering the wound.

[0003] However, these traditional hemostatic patches have a significant disadvantage: they cannot actively exert sufficient pressure on the wound. When encountering a large amount of bleeding or severe vascular injury, relying solely on the hemostatic patch itself is insufficient to quickly and effectively stop bleeding. Therefore, in actual application, medical personnel or the patient himself usually needs to press the wound for a long time with his hand or other tools to achieve hemostasis. This approach not only increases the operator's burden but also may result in poor hemostasis due to uneven pressure or insufficient time, and even cause unnecessary pain or tissue damage.

[0004] In addition, long-term manual compression may limit the patient's activity ability, especially in special environments such as outdoor first aid or battlefield rescue, which may affect rescue efficiency and treatment effect. Moreover, for some patients with limited mobility or self-care ability, manual compression hemostasis method is more difficult to implement. SUMMARY

[0022] The implementation of the utility model has the following beneficial effects:

[0023] The utility model relates to a compression hemostatic patch, compared with the traditional hemostatic patch which relies on artificial compression, the utility model can automatically generate inflation effect when being used, so that continuous and uniform pressure is applied to the wound. This not only improves the hemostatic efficiency, but also reduces the work burden of medical staff.

[0024] In use, the user only needs to place the compression hemostatic patch on the bleeding point, and fix it through the adhesive tape, then press the elastic plate gently, so that the broken piece pierces or breaks the broken bag, and the liquid in the broken bag for foaming overflows and contacts the foaming agent, thereby activating the foaming agent, and the foaming agent foams and expands to make the expansion bag expand and expand, so as to achieve the purpose of compression hemostasis. The process of the product is very convenient, and no professional skill is needed to operate, and it is suitable for rapid response in various emergency situations.

[0036] Figure 1 And Figure 2 The compression hemostatic patch 10 in some embodiments of the present application is shown, which is used for compression hemostasis of a wound. As shown in Figures 1 to 5 The compression hemostatic patch 10 includes gauze 1, foaming assembly 2, piercing assembly 3 and adhesive tape 4, the foaming assembly 2 is connected to the gauze 1, the piercing assembly 3 is connected to the foaming assembly 2, and the adhesive tape 4 is connected to the piercing assembly 3. It can be understood that the gauze 1 is a common medical gauze in the prior art.

[0037] As shown in Figures 1 to 5 The foaming assembly 2 includes expansion bag 21 and rupture bag 22, the bottom of the expansion bag 21 is connected to the gauze 1, the rupture bag 22 is arranged in the expansion bag 21, the foaming agent is arranged between the expansion bag 21 and the rupture bag 22, and the foaming liquid is arranged in the rupture bag 22.

[0038] The piercing assembly 3 comprises a resilient plate 31 and a rupturing member 32. The bottom of the resilient plate 31 is provided with a relief hole 311, and the top of the inflation bag 21 is connected to the hole wall of the relief hole 311. The rupturing member 32 is arranged on the resilient plate 31, and the end of the rupturing member 32 faces the inflation bag 21. The bottom of the adhesive tape 4 is connected to the top of the resilient plate 31.

[0039] When the resilient plate 31 is deformed by force and drives the rupturing member 32 to move towards the inflation bag 22, the inflation bag 22 is ruptured by the puncture or compression of the rupturing member 32 to flow out the foaming liquid, so that the foaming agent contacts the foaming liquid to foam and expand the inflation bag 21.

[0040] It can be understood that the gauze 1 is a common medical gauze in the prior art, which mainly functions to directly cover the wound and provide protection. When the inflation bag 22 is pierced, the foaming agent mixes with the foaming liquid to generate a large amount of gas or the foaming agent foams and expands, so that the inflation bag 21 rapidly expands to exert pressure on the wound. When it is necessary to compress the wound to stop bleeding, the rupturing member 32 pierces or ruptures the inflation bag 22 by pressing the resilient plate 31, triggering the foaming reaction or the gas generation reaction. The adhesive tape 4 is used to fix the entire device at the wound, and when the inflation assembly 2 expands, the adhesive tape 4 can limit the top of the inflation assembly 2, so that the pressure formed by the expansion of the inflation assembly 2 is fully transmitted to the gauze and further compresses the wound to form compression hemostasis through the gauze.

[0041] The gauze 1 can be made of cotton fibers, which has good water absorption and air permeability. The inflation bag 21 can be made of flexible plastic materials such as polyethylene (PE) or polypropylene (PP), which ensures that it has sufficient flexibility and pressure resistance. The inflation bag 21 can rapidly expand after the foaming agent mixes with the foaming liquid to exert uniform pressure on the wound. The inflation bag 22 can be made of thin and fragile materials such as polyester film or similar fragile materials. The inflation bag 22 contains the foaming liquid, which flows out and mixes with the foaming agent when the inflation bag 22 is pierced or ruptured by the rupturing member 32.

[0042] The resilient plate 31 can be made of plastic or metal materials with certain elasticity. The resilient plate 31 can be deformed by being pressed by medical staff or users, so that the resilient plate 31 drives the rupturing member 32 to pierce or rupture the inflation bag 22. The rupturing member 32 pierces or ruptures the inflation bag 22 when pressed to release the foaming liquid. The adhesive tape 4 can be a medical-grade adhesive bandage or similar material, which can fix the entire device at the wound to ensure that it does not shift during use.

[0043] It should be noted that the volume of the inflation bag 22 can be flexibly set, and the specific setting is determined according to the statistical ratio of the foaming agent and the foaming liquid configured by different materials, so as to ensure that the inflation of the inflation bag 21 can form the pressure required for compression hemostasis.

[0044] As shown in FIG. 1, the compression hemostatic patch 10 comprises a compression plate 1, a plurality of elastic plates 31, a plurality of elastic arcs 312, a plurality of breakers 32, a plurality of breakage bags 22, a plurality of inflation bags 21, and a plurality of adhesive pads 4. Figures 1 to 5 As shown in FIG. 2, in some embodiments of the compression hemostatic patch 10, the inflation bag 21 comprises a silica gel bag, the breakage bag 22 is arranged in the silica gel bag, and a foaming agent is arranged between the silica gel bag and the breakage bag 22.

[0045] It can be understood that the inflation bag 21 uses silica gel as its main structural material. Silica gel is a synthetic rubber with high elasticity and durability, and is mild and non-irritating to the skin. The inside of the silica gel bag contains the breakage bag 22 and the foaming agent. When the breakage bag 22 is pierced or broken, the foaming agent reacts with the foaming liquid in the breakage bag 22 to produce gas, causing the silica gel bag to rapidly inflate. Due to the high elasticity and sealing performance of silica gel, it can effectively maintain the inflated state and uniformly transmit pressure to the wound area, thereby helping to stop bleeding. Of course, the foaming agent and the foaming liquid can be configured as other materials that can foam and expand without generating gas in the prior art.

[0046] Specifically, the inflation bag 21 comprises a TPE inflation bag. It can be understood that TPE is a material that combines the elasticity of rubber and the processability of plastic, with good flexibility, durability, and biocompatibility. Further, the elastic properties of the TPE material enable the inflation bag 21 to uniformly transmit pressure to the wound area when inflated, providing consistent compression hemostatic effect.

[0047] Specifically, the foaming agent comprises an inflation sponge. It can be understood that when the breakage bag 22 is broken, the foaming liquid will flow out and come into contact with the inflation sponge. The inflation sponge rapidly absorbs the liquid and expands to inflate the inflation bag 21.

[0048] As shown in FIG. 3, in some embodiments of the compression hemostatic patch 10, the inner wall surface of the avoidance hole 311 is provided with an elastic arc surface 312, and the breaker 32 is arranged at the center of the elastic arc surface 312. Figures 1 to 5 It can be understood that the elastic arc surface 312 is arc-shaped or hemispherical. The elastic arc surface 312 is arranged on the inner wall surface of the avoidance hole 311 and located at the top of the inflation bag 21. This design allows the elastic arc surface 312 to directly act on the breaker 32 when the elastic plate 31 is pressed, ensuring that the stroke of the breaker 32 is maximized, thereby ensuring that the breaker 32 can act on the breakage bag 22.

[0049] Further, in some embodiments of the compression hemostatic patch 10, the piercing assembly 3 comprises a plurality of breakers 32, and each breaker 32 is symmetrically arranged on the elastic plate 31.

[0050] It can be understood that the plurality of breakers 32 can act on the breakage bag 22 from a plurality of different positions respectively, ensuring that the breakage bag 22 can be broken in time when needed.

[0051] ​

[0052] like Figures 1 to 5 As shown, in some embodiments of the compression hemostatic patch 10, the rupture part 32 includes a fixing part 321 and a rupture part 322. The rupture part 322 is connected to the fixing part 321. The fixing part 321 is disposed on the elastic plate 31. The rupture part 322 is exposed in the relief hole 311.

[0053] Understandably, the fixing part 321 can be made of a material with a certain strength and stability, such as medical-grade plastic (e.g., polypropylene PP or polycarbonate PC). The main function of the fixing part 321 is to securely connect the broken part 32 to the elastic plate 31, ensuring that the broken part 32 will not shift or fall off during the pressing process.

[0054] The rupture section 322 can be configured in a dome, cone, or other shape suitable for supporting the rupture package 22. Its design should ensure that the rupture package 22 can rupture evenly and effectively under pressure. The rupture section 322 acts on the rupture package 22 by supporting it, causing it to rupture at a predetermined weak point and releasing the foaming liquid.

[0055] It should be noted that the rupture part 322 can be configured to rupture the rupture pack 22 by supporting it. In this case, the rupture part 322 can support the expansion pack 21 to deform and abut against the rupture pack 22 through the side wall of the expansion pack 21, causing the rupture pack 22 to rupture and release the foaming liquid. Alternatively, the rupture part 322 can be configured to rupture the rupture pack 22 by puncturing it. In this case, the rupture part 322 can puncture the side wall of the expansion pack 21 and further penetrate into the rupture pack 22, causing the foaming liquid inside the rupture pack 22 to flow out.

[0056] Specifically, the rupture portion 322 includes a needle or a pressure head.

[0057] Understandably, the choice between a needle or a pressure head depends on the type of mixture or compound used between the foaming agent and the foaming liquid. For example, if the foaming agent and foaming liquid produce gas after mixing, the rupture part 322 is configured as a pressure head to prevent the rupture part 322 from puncturing the expansion pack 21 and causing leakage during subsequent expansion. If the foaming agent is not a liquid, and the hemostatic pressure is achieved through the expansion of the foaming agent after mixing with the foaming liquid, then the rupture part 322 can be configured as a needle.

[0058] like Figures 1 to 5 As shown, in some embodiments of the compression hemostatic patch 10, the bottom of the ruptured pack 22 is adhered to the bottom of the expansion pack 21, the bottom of the expansion pack 21 is adhered to the top of the gauze 1, the top of the expansion pack 21 is adhered to the elastic plate 31, and the top of the elastic plate 31 is adhered to the adhesive tape 4.

[0059] Understandably, the parts can be bonded together using acrylic or silicone adhesives. Alternatively, polyethylene or polyurethane hot melt adhesives can also be used.

[0060] like Figures 1 to 5 As shown, in some embodiments of the pressure bandage 10, the pressure bandage 10 further includes a release liner 5, which is detachably connected to the bottom of the adhesive tape 4 and covers the foaming component 2 and the puncture component 3.

[0061] Understandably, when the isolation film 5 is attached to the adhesive tape 4, it ensures that the gauze 1, foaming component 2 and puncture component 3 are not contaminated during storage and transportation, and ensures that each component is clean and sterile before use.

[0062] Specifically, the ruptured package 22 includes a plastic package.

[0063] Understandably, the burst package 22 is made of plastic to ensure good sealing during storage and transportation, preventing leakage of the foaming liquid. Furthermore, pre-set weak points or tiny grooves can be provided on the plastic package, which will break first when subjected to external force.

[0064] Furthermore, the wall thickness of the plastic bag is configured to be between 0.05 mm and 0.1 mm to ensure that it can easily break under appropriate pressure.

[0065] Specifically, the foaming agent can be alginate or SAPs (superabsorbent polymers).

[0066] In another embodiment, the foaming agent can be configured as baking soda, the foaming liquid can be configured as acetic acid, the rupture package can be configured as being made of polyester, and the expansion package can also be configured as being made of polyester.

[0067] Furthermore, the expansion pack and the burst pack can be manufactured as a single piece and a partition can be formed in the internal cavity to separate two chambers, one for containing baking soda and the other for containing acetic acid.

[0068] like Figure 1 As shown, the periphery of the gauze 1 extends outward to form an edge 11, which is connected to the adhesive tape 4. The gauze 1 covers the foaming component 2 and the puncture component 3.

[0069] Understandably, the gauze 1 can effectively cover the foaming component 2 and the puncture component 3 through the edge wrapping 11, thereby positioning the foaming component 2 and the puncture component 3 to a certain extent, thus ensuring the normal operation of the foaming component 2 and the puncture component 3 and ensuring the product's pressure hemostasis function.

[0070] like Figure 3 and​ As shown in the drawings, the adhesive tape 4 is provided with a pressing guide 41 on the surface away from the puncture assembly, and the pressing guide 41 is aligned with the breaking piece 32.

[0071] Understandably, the pressing guide 41 is used to guide the medical staff or the user to press correctly, so as to ensure that the breaking piece 32 can correctly puncture or break the breaking bag 22.

[0072] It should be noted that the pressing guide 41 can be provided in the following forms:

[0073] Visual mark: an obvious mark or pattern, such as an arrow, a dot or a cross, etc., can be printed or pasted on the surface of the adhesive tape 4, which directly points to or is located directly above the breaking piece 32. In this way, the user can know where to apply pressure through the visual mark.

[0074] Tactile prompt: some slight concave or convex structures are designed at the position of the pressing guide 41. When the user touches these structures, the correct pressing position can be intuitively felt, and accurate operation can be achieved even in poor visibility.

[0075] Color contrast: a color obviously different from the rest of the adhesive tape 4 is used as the pressing guide 41, such as if the adhesive tape is white, the pressing guide can be red or other bright colors, so as to attract the attention of the user and guide the user to apply force correctly.

[0076] Instruction words: a short operation guide such as "please press gently here" is attached beside the pressing guide 41, which is used in combination with the icon to help the first-time user better understand how to operate.

[0077] The implementation of the utility model has the following beneficial effects:

[0078] The utility model relates to a compression hemostatic patch, compared with the traditional hemostatic patch which relies on manual compression, the utility model can automatically generate the inflation effect when being used through the built-in foaming assembly and puncture assembly, thereby continuously and uniformly applying pressure to the wound. This not only improves the hemostatic efficiency, but also relieves the work burden of the medical staff.

[0079] When being used, the user only needs to place the compression hemostatic patch on the bleeding point and fix it through the adhesive tape, then gently press the elastic plate, so that the breaking piece punctures or breaks the breaking bag, thereby the liquid in the breaking bag for foaming overflows and contacts the foaming agent, and then the foaming agent is activated, the foaming agent foams and expands to make the inflation bag expand and expand, and the purpose of compression hemostasis is achieved. The process of the product is very convenient, and professional skills are not needed to operate, and it is suitable for rapid response in various emergency situations.

[0080] In addition, since the physical expansion mechanism is adopted to maintain the pressure on the wound, compared with the traditional method of manual pressing or binding, the utility model can provide more stable and reliable compression effect, which helps to reduce the secondary injury risk caused by uneven pressure.

[0081] The utility model has been described in detail above with reference to the drawings. In the above examples, the description of each example has its own focus, and the parts not described in detail in a certain example can be referred to the relevant description of other examples. Those skilled in the art should also know that the actions and modules involved in the specification are not necessarily required by the utility model. In addition, it can be understood that the steps in the utility model example method can be adjusted, combined and reduced in sequence according to actual needs, and the modules in the utility model example device can be combined, divided and reduced according to actual needs.

[0082] The above has described each embodiment of the utility model, and the above description is exemplary, not exhaustive, and is not limited to each disclosed embodiment. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
