Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an infusion pressure hemostatic patch. Background Art

[0002] For arterial puncture, since the arterial wall of the artery is thick and elastic, the blood pressure is much higher than that of the vein (the systolic pressure is usually above 80 mmHg). The wound formed after puncture is prone to continuous bleeding or hematoma formation under high pressure. If hemostasis is not applied in time, it may lead to: bleeding or hematoma: blood extravasates into the subcutaneous or surrounding tissues, forming local swelling and even compressing adjacent nerves and blood vessels.

[0003] Therefore, there are various existing hemostatic patches in the prior art that can apply pressure to the wound. For example, an infusion pressure hemostatic patch proposed in the patent with the application number CN202010175170.9 uses a variety of elastic structures to apply pressure to the wound. However, the disadvantage is that it needs to cooperate with a locking structure to maintain the energy storage state of the elastic structure before the hemostatic patch is used, resulting in the need for an unlocking step during subsequent operations, making the overall operation inconvenient. Moreover, using the above structure, the pressure cannot be adjusted, and excessive pressure will also cause bruising of the wound.

[0004] Another example is the pressure-adjustable directional hemostatic patch proposed in the patent with the application number CN201120254636.0, which "comprises a non-tension adhesive tape 1, a PP plastic spring piece 2, and a disinfected cotton cushion layer 3. A set of equally spaced tearing lines 12 are opened in the right part of the elastic adhesive 1. The PP plastic spring piece 2 is a convex arc-shaped piece. One end extends horizontally to form a connecting part 21, and the other end extends in the middle to form a sheet-shaped adjusting part 22. Three through holes are opened in the connecting part 21, and the connecting part 21 is sewn to the non-tension adhesive tape 1 through these three through holes. The adjusting part 22 can be inserted into the opening formed by the tearing lines 12, and the convex surface of the PP plastic spring piece 2 is bonded with the disinfected cotton cushion layer 3". This hemostatic patch does not need to use an energy storage elastic structure; however, its defect is that the operation is inconvenient and it can only adjust the pressure at the sites of each tearing line, resulting in non-continuous pressure adjustment. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an infusion pressure hemostatic patch, which solves the problems of inconvenient operation and non-continuous pressure adjustment only at the sites of each tearing line in the prior art.

[0006] To achieve the above object, on the one hand, the present invention provides the following technical solutions to achieve: An infusion hemostatic patch, characterized in that it includes: a pressure elastic piece, the pressure elastic piece is a structure with a curvature; and a tension belt, two groups of tension belts are provided, and one end of the tension belt is fixed as a fixed end to one end of the pressure elastic piece, and the other end of the tension belt is a free end. The two groups of tension belts have an intersection point. By applying a tension to the free end of the tension belt, the pressure elastic piece can be deformed to form a state where the midpoint of the pressure elastic piece presses on the bleeding point, and the free end can be pasted on the skin.

[0007] Further, the free end of the tension belt is wound around the outside of one end of the pressure elastic piece and then pasted on the skin.

[0008] Further, the pressure elastic piece has two concentric arc surfaces, and a relief groove is provided between the two arc surfaces, and the relief groove is close to both ends of the pressure elastic piece; the free end of the tension belt passes through the relief groove away from its own fixed end and then is pasted on the skin.

[0009] Further, the two groups of tension belts are respectively a first tension belt and a second tension belt. A narrow belt is provided on the first tension belt, and a hollow opening adapted to the narrow belt is provided on the second tension belt. The narrow belt passes through the hollow opening to form an intersection point of the two groups of tension belts.

[0010] Further, a self-adhesive tape is provided at the free end of one of the tension belts. The self-adhesive tape is folded towards the direction of the other group of tension belts. One surface of the self-adhesive tape close to the two groups of tension belts is an adhesive surface, and a long release film is provided on the adhesive surface. The width of the self-adhesive tape is greater than the width of the pressure elastic piece.

[0011] Further, a first release film is provided at the free ends of the first tension belt and the second tension belt.

[0012] Further, the pressure elastic piece is made of a non-elastic region and an elastic region arranged on the side of the non-elastic region, and the elastic region and the non-elastic region form an arc structure.

[0013] Further, a dressing assembly is provided in the middle of the side of the pressure elastic piece close to the skin. The dressing assembly includes a dressing carrier limited on the pressure elastic piece and a second release film pasted on the other side of the dressing carrier.

[0015] Further, the pressing member includes: a pressing rod, at least one pressing rod is provided, and the pressing rod penetrates through the non-elastic carrier; a force-bearing head, the force-bearing head is fixed at one end of the pressing rod close to the intersection point and is used to bear the pressure at the intersection point.

[0016] The present invention has the following beneficial effects:

[0017] (1). For the infusion pressure hemostatic patch in the first invention, by providing two groups of crossed tension bands and a pressure elastic piece that can deform, the pulling force applied by the operator to the free end of the tension band can act on the pressure elastic piece, so that the pressure elastic piece further arches, forming a state where the midpoint of the pressure elastic piece presses on the bleeding point, and the downward pressure on the wound can be controlled by controlling the magnitude of the pulling force on the tension band, enabling continuous pressure regulation. Compared with the hemostatic patches in the prior art, the hemostatic patch provided by the present invention does not require an unlocking step, has a simple structure, is convenient to operate, and is superior in use.

[0018] (2). For the infusion pressure hemostatic patch in the second invention, two groups of crossed tension bands, side elastic pieces and a pressing member are provided.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0039] Next, according to Figures 1-16 describe the infusion pressure hemostatic patch provided by the embodiments of the present invention.

[0040] On the one hand, the present invention provides a technical solution for the first infusion pressure hemostatic patch.

[0041] Embodiment 1:

[0042] Please refer to Figures 1-3 As shown, the infusion pressure hemostatic patch includes a pressure elastic piece 4 and a tension belt 2. The pressure elastic piece 4 has a curved structure, preferably a C-shaped structure. Two groups of tension belts 2 are provided, and one end of the tension belt 2 is fixed as a fixed end to one end of the pressure elastic piece 4, and the other end of the tension belt 2 is a free end. The two groups of tension belts 2 have an intersection point, and the operator can hold the free end and apply a pulling force to the free end.

[0043] Therefore, by applying a pulling force to the free end of the tension belt 2, the infusion pressure hemostatic patch provided by the present invention can deform the pressure elastic piece 4, so that the pressure elastic piece 4 further arches, forming a state in which the midpoint of the pressure elastic piece 4 presses on the bleeding point. Compared with the hemostatic patches in the prior art, the hemostatic patch provided by the present invention has a simple structure, is convenient to operate, and is superior in use.

[0044] Preferably, the above-mentioned pressure elastic piece 4 is made of elastic PC material.

[0045] Combined with Figure 4 As shown, the free end of the above-mentioned tension belt 2 is wound around the outside of one end of the pressure elastic piece 4 and then pasted on the skin. During specific operation, the nurse aligns the pressure elastic piece 4 with the bleeding point and pulls the free end of the tension belt 2. At this time, the pressure elastic piece 4 arches and presses on the bleeding point, and then the nurse pastes the free end on the skin.

[0046] Combined with Figures 4-7As shown, in order to ensure that after the pressure elastic piece 4 is fixed at the free end position, the situation where the free end adhered to the skin is burst open due to the resilience of the pressure elastic piece 4 is avoided. A self-adhesive tape 1 is provided at the free end of one of the tension bands 2. The self-adhesive tape 1 is folded towards the direction of the other set of tension bands 2 and forms a crease. This crease exists before leaving the factory. One surface of the self-adhesive tape 1 close to the two sets of tension bands 2 is the bonding surface, and a long release film 11 is provided on the bonding surface.

[0047] In this embodiment, after the bonding at the free end is completed, the long release film 11 is removed, and then the self-adhesive tape 1 is adhered to the skin and wound around the organ (hand, arm, leg, etc.) where the bleeding point is located for one circle (the self-adhesive tape 1 will completely cover the pressure elastic piece 4 and the tension band 2). After winding one circle, there is an overlapping area at both ends of the self-adhesive tape 1 to ensure the bonding stability of the self-adhesive tape 1.

[0048] Therefore, the infusion pressure hemostatic patch provided by the embodiment of the present invention can ensure the stability of the pressure elastic piece 4 after deformation through the setting of the longer self-adhesive tape 1.

[0049] Preferably, the width of the self-adhesive tape 1 is greater than the width of the pressure elastic piece 4, so as to ensure that the self-adhesive tape 1 covers the pressure elastic piece 4 in the width direction, and the part wider than the pressure elastic piece 4 is adhered to the skin to improve the stability of the pressure elastic piece 4 after deformation.

[0050] Preferably, the tension band 2 is also made of a bandage, and the self-adhesive tape 1 and the adjacent tension band 2 are of an integral structure.

[0051] Combined Figure 2 and Figure 3 As shown, the above two sets of tension bands 2 are respectively a first tension band 21 and a second tension band 22. A narrow band 212 is provided on the first tension band 21, and a hollowed-out opening 222 adapted to the narrow band 212 is provided on the second tension band 22. The narrow band 212 passes through the hollowed-out opening 222 and forms an intersection point of the two sets of tension bands 2.

[0052] Specifically, as Figure 3 , the first tension band 21 includes a first limiting end 213. The first limiting end 213 is the fixed end of the first tension band 21, which is directly fixed at one end of the pressure elastic piece 4. The first tension end 211 is used as the free end. The narrow band 212 is located between the first tension end 211 and the first limiting end 213. The width of the narrow band 212 is smaller than the widths of the first tension end 211 and the first limiting end 213. One narrow band 212 is shown in the figure.

[0053] Continue to refer to Figure 3The second pull strap 22 includes a second limiting end 223, which serves as a fixed end of the second pull strap 22 and is directly fixed to the other end of the pressure spring sheet 4. The second tension end 221 serves as a free end of the second pull strap 22. The hollow opening 222 is located between the second tension end 221 and the second limiting end 223 and is opposite to the narrow strap 212.

[0054] In addition, the first limit end 213 and the second limit end 223 are limited on the pressure spring piece 4 in a thickened manner. Specifically, assembly holes 41 are opened at both ends of the pressure spring piece 4, and the first limit end 213 and the second limit end 223 are inserted into the corresponding assembly holes 41. Then, thickened polyethylene rods are arranged on the first limit end 213 and the second limit end 223 to thicken the first limit end 213 and the second limit end 223 so that they cannot be detached from the assembly hole 41, thereby fixing the positions of the first limit end 213 and the second limit end 223.

[0055] like Figure 1 and Figure 2 As shown, in order to allow the free end of the tension band 2 to adhere to the skin, adhesive is provided on the side of the free end of the first pull band 21 and the second pull band 22 close to the skin (the side away from the self-adhesive tape 1), and preferably, a first release film 3 is provided on the adhesive.

[0056] Combination Figure 2 and Figure 7 As shown, in order to avoid wound infection, a dressing assembly 5 is provided in the middle of the side of the pressure spring 4 close to the skin. The dressing assembly 5 includes a dressing carrier 51 limited on the pressure spring 4 and a second release film 52 adhered to the other side of the dressing carrier 51. Preferably, the dressing carrier 51 is medical cotton wool impregnated with anti-inflammatory and sterilizing drugs.

[0057] Optionally, the dressing carrier 51 is a circular or polygonal structure.

[0058] In the above structure, after the free end of the tension belt 2 applies tension, the pressure spring sheet 4 arches, causing the dressing carrier 51 in the middle below it to also generate a certain curvature, such as Figure 4 The state shown in the figure causes the outer periphery of the dressing carrier 51 to be lifted, so that it cannot be completely covered on the skin. This is also a common problem caused by applying pressure through the shrapnel in the prior art. Therefore, it is optional, such as Figure 8 As shown, the pressure spring sheet 4 is set as a split structure. The pressure spring sheet 4 is made of a non-elastic area 402 and an elastic area 401 arranged on the side of the non-elastic area 402. The elastic area 401 and the non-elastic area 402 form an arc structure, such as Figure 8 As shown, in this structure, when the free end of the tension band 2 is subjected to force, only the elastic region 401 can be deformed, thereby ensuring that the dressing carrier 51 completely covers the skin.

[0059] Preferably, the elastic region 401 is made of elastic PC, and the inelastic region 402 is made of inelastic PC.

[0060] Operating method: In the initial state, the pressure elastic sheet 4 is in an undeformed state. The operator needs to remove the first release film 3 and the second release film 52, then align the dressing carrier 51 with the wound and press it on the wound. Then, apply a pulling force to the second pulling end 221 and the first pulling end 211 (when applying the pulling force, the operator needs to apply a certain pressure to the second pulling end 221 and the first pulling end 211 to ensure that the deformation amount of the pressure elastic sheet 4 acts in the direction of the wound, rather than in the direction away from the wound). When the pressure is in place, the dressing carrier 51 has been completely pressed on the wound. At this time, paste the free end on the skin, then remove the long release film 11, and then paste the self-adhesive tape 1 on the skin and wrap it around the organ where the bleeding point is located (hand, arm, leg, etc.) in a circle (the self-adhesive tape 1 will completely cover the pressure elastic sheet 4 and the pulling belt 2). After wrapping a circle, there is an overlapping area at both ends of the self-adhesive tape 1 to ensure the adhesive stability of the self-adhesive tape 1.

[0061] Embodiment 2:

[0062] Combined with Figures 9-12 As shown, the difference between this embodiment and Embodiment 1 is that a relief groove 42 is provided on the pressure elastic sheet 4 here. Specifically, the pressure elastic sheet 4 has two concentric arc surfaces, the relief groove 42 is located between the two arc surfaces, and the relief groove 42 is close to both ends of the pressure elastic sheet 4. In this embodiment, the free end of the pulling belt 2 passes through the relief groove 42 far from its fixed end and is then pasted on the skin.

[0063] The reason for setting the relief groove 42 for the pulling belt 2 to pass through is to expand the utilization rate of the free end of the pulling belt 2. That is, in this embodiment, the free end passing through the relief groove 42 can be directly pasted on the skin, and it does not need to pass through the end of the pressure elastic sheet 4 far from the skin, thereby improving the utilization rate of the free end of the pulling belt 2, enabling it to contact and bond to the skin after passing through the relief groove 42, and also being able to better maintain the stability of the pressure elastic sheet 4.

[0064] In addition, one of the above-mentioned sets of relief grooves 42 is for making way for the narrow belt 212 on the first pulling belt 21, and there is one such narrow belt 212. The other set of relief grooves 42 is for making way for the area on the second pulling belt 22 opposite to the hollow opening 222.

[0065] This embodiment can also adopt the structure of the split pressure elastic sheet 4 in Embodiment 1, as Figure 11 and Figure 2 shown.

[0066] Operation method: In the initial state, the pressure elastic piece 4 is in an undeformed state. The operator needs to remove the first release film 3 and the second release film 52, then align the dressing carrier 51 with the wound and press it on the wound. Then, apply a pulling force to the second pulling end 221 and the first pulling end 211 (when applying the pulling force, the operator needs to apply a certain pressure to the second pulling end 221 and the first pulling end 211 to ensure that the deformation of the pressure elastic piece 4 acts in the direction of the wound rather than in the direction away from the wound). When the pressure is in place, the dressing carrier 51 has been completely pressed on the wound. At this time, stick the free end to the skin, then remove the long release film 11, and then stick the self-adhesive tape 1 to the skin and wrap it around the organ where the bleeding point is located (hand, arm, leg, etc.) in a circle (the self-adhesive tape 1 will completely cover the pressure elastic piece 4 and the pulling belt 2). After wrapping a circle, there is an overlapping area at both ends of the self-adhesive tape 1 to ensure the adhesion stability of the self-adhesive tape 1.

[0067] On the other hand, as shown in Figures 13-16 The present invention also provides another infusion pressure hemostatic patch. As the second invention, the infusion pressure hemostatic patch includes a non-elastic carrier 6, side elastic pieces 7, a pulling belt 2, and a pressing member 8.

[0068] Specifically, the non-elastic carrier 6 is an undeformable plate-like structure. Two groups of side elastic pieces 7 are provided and are respectively fixed at both ends of the upper surface of the non-elastic carrier 6. Two groups of pulling belts 2 are provided, and one end of the pulling belt 2 is fixed as a fixed end at the upper end of the side elastic piece 7, and the other end of the pulling belt 2 is a free end passing through the side elastic piece 7. The two groups of pulling belts 2 form an intersection point in the middle of the non-elastic carrier 6. The pressing member 8 penetrates through the middle of the non-elastic carrier 6, and the pressing member 8 can produce a small displacement on the non-elastic carrier 6 in a direction perpendicular to the skin. The intersection point is located on the upper surface of the pressing member 8.

[0069] Preferably, a rectangular through-hole 71 for the free end to pass through is provided at a position close to the lower part of the side elastic piece 7.

[0070] For example, Figure 14 In, the first pulling belt 21 includes a first limiting end 213, a narrow belt 212, and a first pulling end 211 arranged in sequence; the second pulling belt 22 includes a second limiting end 223, a hollow opening 222, and a second pulling end 221 arranged in sequence; wherein the first limiting end 213 and the second limiting end 223 are respectively fixed at the upper end of the side elastic piece 7, the hollow opening 222 and the narrow belt 212 are adapted, and the first pulling end 211 and the second pulling end 221 are free ends.

[0071] In the present invention, the bonding method of the first pulling end 211 and the second pulling end 221 to the skin is the same as that in the first invention, and both are bonded to the skin using an adhesive.

[0072] Specifically, as shown in Figure 15 and Figure 16As shown in the figure, the above-mentioned pressing member 8 includes a pressing rod 82 and a force-bearing head 81. There is at least one pressing rod 82, and the pressing rod 82 penetrates through the inelastic carrier 6. The force-bearing head 81 is fixedly arranged at one end of the pressing rod 82 close to the intersection point for bearing the pressure at the intersection point.

[0073] Preferably, a dressing component 5 is arranged at the lower end of the pressing rod 82, and this dressing component 5 is the same as that in the first invention.

[0074] Preferably, a self-adhesive tape 1 same as that in the first invention is also arranged on one of the tension bands 2 to ensure the stability of the pressing rod 82 pressing on the bleeding point in the present invention.

[0075] In this embodiment, before the staff operates, the first pull band 21 and the second pull band 22 are in a relaxed state and do not exert pressure on the force-bearing head 81. During the operation, the first release film 3 and the second release film 52 are removed. Then, hold the free end of the tension band 2, and then align the dressing carrier 51 with the wound. Subsequently, apply a pulling force to the free end of the tension band 2, so that the two side elastic pieces 7 are pulled and move inwards to converge; at this time, the intersection point of the two groups of tension bands 2 moves downward, thereby generating a downward pressure on the force-bearing head 81. Then, the pressing rod 82 presses the dressing carrier 51 tightly on the wound. Here, the displacement amount of the pressing rod 82 can be controlled by controlling the magnitude of the pulling force on the tension band 2, so as to control the downward pressure on the wound.
