Description

Technical Field

[0001] This invention relates to the field of hemostasis equipment technology, and more specifically to a multi-purpose wearable hemostasis device. Background Technology

[0002] Even a small problem can lead to a major accident. Especially when encountering a sudden sick or injured person in the wild, appropriate first aid measures should be taken according to the different situations (the faster the treatment, the better), and then try to get them to a hospital as soon as possible. In the case of accidents with large amounts of bleeding, it is necessary to use hemostatic equipment in time to avoid excessive blood loss and harm to the body.

[0003] For outdoor first aid work, medical personnel's first aid kits usually need to carry hemostatic equipment for different bleeding sites. For example, for bleeding in the limbs, hemostatic sleeves are needed. By inflating the hemostatic sleeves, pressure is applied to the bleeding site to reduce bleeding. For bleeding in the chest, abdomen, or lower back, hemostatic vests are used for inflation to stop the bleeding. This operation is relatively simple and quick. Nowadays, hemostatic equipment often has an embedded air bladder. The air bladder is inflated and applied to stop the bleeding. The embedded air bladder is mostly an independent air bladder or a long strip air bladder, so that the air bladder can be inflated for a specific injured area.

[0004] However, the above-mentioned hemostasis devices also have the following drawbacks: long strip-shaped airbags are obviously not suitable for hemostasis operations on the legs or arms, and embedded airbags mostly form a ring around the arms or legs, which obviously cannot achieve point-to-point hemostasis operations. Moreover, the ring-type hemostasis method can easily cause blood flow blockage, affecting the safety of use.

[0005] However, since different people have different body shapes and sizes, the injured area may be located between the two airbags. Since the surface of the inflated independent airbags is mostly curved, the injured area may deviate from the optimal compression position of the airbag or be located in the compression blind zone between the two airbags. In this case, the targeting and positioning of this hemostasis operation is relatively poor. Therefore, the position of the hemostasis device worn needs to be constantly adjusted during use. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-purpose wearable hemostasis device to solve the technical problems in the prior art of lacking hemostasis components that can be disassembled into multiple uses and needs, and the inaccurate hemostasis position caused by setting an airbag in the interlayer of the hemostasis device.

[0007] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0008] A multi-purpose wearable hemostatic device includes two single-sided wearable fabrics, which are detachably connected by a shoulder strap at their upper end and a zipper on their side.

[0009] The outer surfaces of both single-sided wearable fabrics are provided with multiple nylon strips. The upper ends of all nylon strips are sewn onto the single-sided wearable fabric. The nylon strips are provided with detachable compression airbag assemblies. The compression airbag assemblies can be detachably attached to different positions on the nylon strips to achieve point hemostasis at different bleeding locations.

[0010] The nylon strips are distributed horizontally and parallel to the surfaces of the two single-sided wearable fabrics, and each nylon strip is provided with multiple holes and slots as suspension points for installing the compression airbag assembly.

[0011] The compression airbag assembly includes a hollow concave panel and four shaping rods hinged to the four corners of the hollow concave panel. A rubber airbag is fixedly installed inside the hollow concave panel. The ends of the shaping rods are provided with nylon pads, and the nylon pads are provided with hidden buckles in the grooves for fixing to nylon strips.

[0012] As a preferred embodiment of the present invention, the hollow concave panel is provided with slots at the four corners, and vertical uprights are installed in the slots. One end of the shaping rod is movably installed on the vertical upright through a hollow tube and rotates around the vertical upright. The hollow concave panel changes the horizontal and vertical span of the nylon strip by the movably installed shaping rod.

[0013] As a preferred embodiment of the present invention, each of the four edges of the hollow concave panel is hinged with a triangular hinge plate. When all the triangular hinge plates are rotated to coincide with the surface of the hollow concave panel, their total area is the same as the area of ​​the hollow concave panel. When all the triangular hinge plates are rotated to be flush with the surface of the hollow concave panel, they form a rectangular shape to expand the pressure hemostasis area of ​​the rubber airbag.

[0014] As a preferred embodiment of the present invention, the rubber airbag is installed on the same side surface of the hollow concave panel and the triangular hinge plate. The hollow concave panel has an opening at its center. An air outlet and an air inlet are formed in the opening through an air valve. The opening is connected to an air pump to realize the inflation operation of the rubber airbag.

[0015] As a preferred embodiment of the present invention, the apex of the triangular hinge plate is provided with an arc-shaped groove, and the arc-shaped grooves of all the triangular hinge plates are combined to form a hole with the same diameter as the opening. The center of the four sides of the opening is provided with a mounting post, and the arc-shaped groove is provided with a fixing kit that hangs on the mounting post.

[0016] As a preferred embodiment of the present invention, an elastic rope is provided at one of the four corners of the hollow concave panel, and a fixed protrusion is provided at the corner position parallel to the elastic rope. The elastic rope passes through the four sides of the hollow concave panel and the end of the elastic rope is fixed on the fixed protrusion.

[0017] The elastic rope is positioned between the shaping rod and the triangular hinge plate.

[0018] As a preferred embodiment of the present invention, the four sides of the hollow concave panel are provided with limiting grooves for the elastic rope to tightly cover it. The elastic rope is used to divide the rubber airbag along the four sides of the hollow concave panel to prevent the filled gas from entering the rubber airbag of the triangular hinge plate.

[0019] As a preferred embodiment of the present invention, both sides of the single-sided wearable fabric are provided with size adjustment straps, the size adjustment straps including tension cords and pig nose spring buckles provided on both sides of a single single-sided wearable fabric;

[0020] The two single-sided wearable fabrics are connected by multiple tension ropes and pig-nose spring buckles on the same side, and a single single-sided wearable fabric is connected by multiple tension ropes and pig-nose spring buckles on both sides, so as to achieve the wrapping and fixing of the hemostatic vest formed by the two single-sided wearable fabrics, or to achieve the fixing of the single hemostatic piece formed by the single single-sided wearable fabric.

[0021] As a preferred embodiment of the present invention, the tension rope passes through the holes and grooves on the nylon strip and then through the pig nose spring buckle to form the hemostatic vest and the single-sided hemostatic device of different sizes.

[0022] As a preferred embodiment of the present invention, the single-sided wearable fabric has a double-sided structure. The inner layer of the single-sided wearable fabric is cotton fabric, and the outer layer of the single-sided wearable fabric is non-elastic nylon fabric. The side of the single-sided wearable fabric has a slit hole between two strips of nylon fabric. A button is provided on one side of the slit hole. A disposable hemostatic cloth is provided on the inner surface of the single-sided wearable fabric. A hook edge is provided at the edge of the disposable hemostatic cloth, and the disposable hemostatic cloth is fixed to the button by the hook edge.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] The hemostatic device of this invention can not only be used as a vest to stop bleeding in the chest, abdomen, and back areas of the human body, but also can be disassembled and used separately. It can be split in two at the shoulder, and the two separate strips can be used independently to stop bleeding in the limbs, head, and neck areas of the human body. This achieves multiple uses with one device. For outdoor first aid activities, one hemostatic device can be used to treat different parts of the human body, thereby improving emergency response efficiency.

[0025] In addition, the present invention provides a detachable airbag on the outer layer of the hemostasis device. The position of the airbag can be used for targeted and precise compression hemostasis according to the location of the injury. The optimal curved position of the inflated airbag is aligned with the injury location, thereby improving the effectiveness of hemostasis. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, this invention provides a multi-purpose wearable hemostasis device. This hemostasis device can not only be used as a vest to stop bleeding in the chest, abdomen, and back, but it can also be disassembled and used separately. It can be split in two at the shoulder, and the two separate strips can be used independently to stop bleeding in the limbs, head, and neck, thus achieving multiple uses in one device. For outdoor emergency rescue activities, using one hemostasis device to treat different parts of the body improves emergency response efficiency.

[0038] The wearable hemostasis device in this embodiment specifically includes:

[0039] It includes two single-sided wearable fabrics 1, which are detachably connected by shoulder straps at their upper ends and zippers on their sides. The two single-sided wearable fabrics 1 are connected by shoulder straps at their upper ends and zippers on their sides to form a wrap-around hemostatic vest, and a single single-sided wearable fabric 1 is connected by zippers on its side to form a single-sided hemostatic device.

[0040] Both single-sided wearable fabrics 1 have zipper connecting strips on the same side, and both sides of the two single-sided wearable fabrics 1 have size adjustment straps 5 outside the zipper connecting strips. The zipper connecting strips and shoulder straps connect the single-sided wearable fabrics 1 to form a hemostatic vest. The size adjustment straps 5 are used to adjust the size of the formed hemostatic vest to suit people with different waist sizes.

[0041] The zipper connecting strips on the two sides of the front-facing fabric 1 are adapted and joined together, and the zipper connecting strips on the two sides of the back-facing fabric 2 are adapted and joined together. The front-facing fabric 1 and the back-facing fabric 2 are connected by the zipper connecting strips on their respective sides to form a single-sided hemostatic device, which can be used to adapt to different bleeding locations on the human body.

[0042] The two side size adjustment straps 5 of the front wearing cloth 1 are adapted and connected, and the two side size adjustment straps 5 of the back wearing cloth 2 are adapted and connected. The front wearing cloth 1 and the back wearing cloth 2 are connected by their respective side size adjustment straps 5 to adjust the size of the single-sided hemostatic device.

[0043] The surface of the single-sided wearable cloth 1 is provided with multiple evenly distributed nylon strips 6. A compression airbag assembly 7 is detachably provided on the nylon strips 6. The compression airbag assembly 7 can be attached to different positions of the nylon strips 6 to achieve local hemostasis at different bleeding locations.

[0044] Most existing hemostatic devices typically have an airbag installed within the device's internal structure. This allows for targeted inflation of the airbag at a specific injury site. However, due to variations in body size, the injury site may be located between two airbags. Since the surface of the inflated airbags is often curved, the injury site may deviate from the optimal compression position of the airbag or fall into the compression blind zone between the two airbags. Consequently, the targeting and positioning of this hemostatic operation are relatively poor, requiring constant adjustments to the position of the worn hemostatic device during use.

[0045] As a preferred embodiment of this invention, instead of placing the airbag inside the interlayer of the hemostasis device, a detachable airbag is placed on the outer layer of the hemostasis device. In this way, the position of the airbag can be used for targeted and precise compression hemostasis according to the location of the injury. The optimal curved position of the inflated airbag is aligned with the injury location, thereby improving the effectiveness of hemostasis.

[0046] Therefore, as a preferred embodiment, when the zipper connecting strip of the single-sided wearable fabric 1 and the movable connecting component 3 are connected to form a hemostatic vest, and it is worn on the upper body of the human body, the compression airbag component 7 can be accurately hung at the bleeding location to perform targeted hemostasis.

[0047] It is worth noting that the current method of placing the airbag inside the vest requires an inflation / deflation port, which can cause discomfort. To reduce this discomfort, sponge or other soft fabric is added to the hemostatic vest. However, for reusable hemostatic vests, blood may enter the vest during use, requiring cleaning and disinfection before use.

[0048] However, in this embodiment, the compression airbag assembly 7 is set to be external, which can improve the comfort of the human body when wearing the hemostatic vest. For example, if there is bleeding in the chest or abdomen, the back of the cloth 2 does not need to be equipped with an airbag, so there will be no discomfort even when lying down.

[0049] Based on the above description, the front and back wearing fabrics in this embodiment do not need to be thickened or filled with soft material; instead, they can be made of non-deformable nylon material, which can reduce the cost.

[0050] In this embodiment, a locking element exists between the zipper connecting strips on the two sides of each single-sided wearable fabric 1, which can directly merge the zipper teeth on the two sides of the front wearable fabric 1. Furthermore, a locking element also exists on the zipper connecting strips on the same side of both single-sided wearable fabrics 1, which can directly merge the zipper teeth on the same side of both single-sided wearable fabrics 1. Thus, combined with the shoulder straps, the single-sided wearable fabrics 1 can be assembled into a vest shape.

[0051] Since the purpose of setting the zipper connecting strip is to increase the usable area, and the size adjustment strip 5 is to achieve the fixation ability during use, when the zipper connecting strip is closed, the single-sided wearable fabric 1 does not wrap around the surface of the human body, but there is a gap between it and the human body. In this case, when the airbag assembly 7 is squeezed and fastened, it is easy to shake, resulting in poor hemostasis.

[0052] To address this issue, this embodiment utilizes a size adjustment strap 5 to adjust the tightness of the hemostatic vest or single-sided hemostatic patch for people of different body types, thereby ensuring that the hemostatic vest or single-sided hemostatic patch does not shake and remains firmly attached to the human body surface.

[0053] The size adjustment band 5 includes tension cords 51 and pig nose spring buckles 52 disposed on both sides of a single single-sided wearable fabric 1. Two single-sided wearable fabrics 1 are connected by multiple tension cords 51 and pig nose spring buckles 52 on the same side, and a single single-sided wearable fabric 1 is connected by multiple tension cords 51 and pig nose spring buckles 52 on both sides, so as to achieve the wrapping fixation of the hemostatic vest formed by the two single-sided wearable fabrics 1, or to achieve the fixation of the single hemostatic component formed by the single single-sided wearable fabric 1.

[0054] The tension rope 51 is passed through the slot 2 on the nylon strip 6 and then through the pig nose spring buckle 52 to form hemostatic vests and single-sided hemostatic devices of different sizes.

[0055] For outdoor rescue, the ease of use of a rescue device directly affects the speed of treatment. This implementation method can achieve faster hemostasis and more precise and stable hemostasis compared to existing technologies, whether for hemostasis of the limbs or the chest, abdomen, waist and back.

[0056] In this embodiment, the method of fixing the hemostatic vest or the single-sided hemostatic device is as follows: the tension rope 51 is passed through the pig nose spring buckle 52, and the redundant space between the tension rope 51 and the pig nose spring buckle 52 is contracted, thereby achieving the hemostatic vest or the single-sided hemostatic device to be tightly covered on the hemostatic position.

[0057] When the tension cord 51 is fully tightened, if the hemostatic vest or single-sided hemostatic device still cannot be tightly covered at the hemostatic position, the tension cord 51 is first passed through the hole groove 2 on the nylon strip 6, and then through the pig nose spring buckle 52, thereby reducing the redundant space between the installation position of the tension cord 51 and the hole groove 2, thereby further realizing the fixation operation of the hemostatic vest or single-sided hemostatic device.

[0058] Among them, the hemostatic vest refers to the upper part of the human body, the waist, abdomen and back, which is wrapped and worn. The single-sided hemostatic piece connects the two sides of a single single-sided wearable cloth 1 with a zipper and is fixed by a tension rope 51 and a pig nose spring buckle 52, thereby achieving the fixed hemostatic operation of the legs or arms.

[0059] Since the hemostasis device in this embodiment can be used as a hemostasis device for the upper body, as well as for the legs or arms, the existing embedded airbag installation method is obviously not suitable for hemostasis operations on the legs or arms. Embedded airbags mostly form a ring around the arms or legs, which obviously cannot achieve point-to-point hemostasis operations. Moreover, the ring-type hemostasis method can easily cause blood flow blockage, affecting the safety of use.

[0060] To solve the above technical problems, such as Figure 2 As shown, in this embodiment, multiple nylon strips 6 are provided on the outer surface of both single-sided wearable fabrics 1. The upper ends of all nylon strips 6 are sewn onto the single-sided wearable fabric 1. A detachable compression airbag assembly 7 is provided on the nylon strip 6. The compression airbag assembly 7 can be detachably attached to different positions on the nylon strip 6 to achieve point hemostasis at different bleeding locations.

[0061] Among them, the nylon strips 6 are distributed horizontally and parallel to the surfaces of the two single-sided wearable fabrics 1, and each nylon strip 6 is provided with multiple holes and slots 2 as suspension points for installing the compression airbag assembly 7.

[0062] like Figure 3 and Figure 4 As shown, the compression airbag assembly 7 includes a hollow concave panel 71 and four shaping rods 73 hinged to the four corners of the hollow concave panel 71. A rubber airbag 72 is fixedly installed inside the hollow concave panel 71. The ends of the shaping rods 73 are provided with nylon pads 74. The nylon pads 74 are provided with hidden buckles 75 for fixing in the slots 2 on the nylon strips 6.

[0063] As a preferred embodiment, the hollow concave panel 71 has slots 3 at its four corners, and vertical poles 4 are installed in the slots 3. One end of the shaping rod 73 is movably mounted on the vertical pole 4 through the hollow tube 8 and rotates around the vertical pole 4. The hollow concave panel 71 changes the horizontal and vertical span of the nylon strip 6 by the movably mounted shaping rod 73.

[0064] For example, when the shaping rod 73 is rotated horizontally, the distance between two parallel shaping rods 73 increases, which can expand the lateral span of the end of the shaping rod 73 on the nylon strip 6. As a result, the movement interval of the hollow concave panel 71 in the lateral position is relatively small, achieving full-coverage hemostasis. At this time, the vertical spacing between the shaping rods 73 decreases, and the nylon strip 6 is folded upward to meet the installation requirements of the shaping rod 73 in the vertical position.

[0065] Similarly, when the shaping rod 73 is rotated vertically, the distance between two parallel shaping rods 73 increases, which expands the vertical span of the end of the shaping rod 73 on the nylon strip 6. As a result, the hollow concave panel 71 moves at a relatively small interval in the vertical position, achieving full-coverage hemostasis. At this time, the lateral spacing between the shaping rods 73 decreases, and the nylon strip 6 is folded to meet the installation requirements of the shaping rod 73 in the lateral position.

[0066] Because the installation position of the shaping rod 73 can deform, and the nylon strip 6 is a flexible structure, the installation position of the shaping rod 73 on the nylon strip 6 can vary, thus meeting the hemostasis requirements at different locations.

[0067] Furthermore, when the rubber airbag 72 is inflated to sufficient pressure, the nylon strip 6 is stretched and supported. The hollow concave panel 71 is fixed to the nylon strip 6 by the shaping rod 73. At this time, the hollow concave panel 71 will not easily shake, thus achieving stable hemostasis at the injured site. As another preferred embodiment, since the compression airbag assembly 7 of this embodiment can be used with hemostatic vests and single-sided hemostatic devices, generally speaking, the area of ​​wounds on the waist, abdomen, chest and back is larger than that of wounds on the arms or legs. Therefore, when using a hemostatic vest, the corresponding hemostasis area requirement is large, and the area requirement of the rubber airbag 72 is large. When using a single-sided hemostatic device, the corresponding hemostasis area requirement is small, and the area requirement of the rubber airbag 72 is small. Therefore, the hollow concave panel 71 in this embodiment is folded to adapt to different hemostasis wearing methods of hemostasis equipment.

[0068] Triangular hinge plates 77 are hinged to the four edges of the hollow concave panel 71. When all the triangular hinge plates 77 are rotated to coincide with the surface of the hollow concave panel 71, the total area is the same as the area of ​​the hollow concave panel 71. When all the triangular hinge plates 77 are rotated to be flush with the surface of the hollow concave panel 71, they form a rectangle to expand the pressure hemostasis area of ​​the rubber airbag 72.

[0069] The rubber airbag 72 is installed on the same side surface of the hollow concave panel 71 and the triangular hinge plate 77. The hollow concave panel 71 has an opening 76 at the center. An air outlet and an air inlet are formed in the opening 76 through an air valve. The opening 76 is connected to an air pump to realize the inflation operation of the rubber airbag 72.

[0070] The triangular hinge plate 77 has an arc-shaped groove 78 at the top corner. All the arc-shaped grooves 78 of the triangular hinge plates 77 are combined to form a hole with the same diameter as the opening 76. The opening 76 has a support column 79 at the center of each of the four sides. The arc-shaped groove 78 has a fixing kit 710 that hangs on the support column 79.

[0071] When the hemostatic device is used for single-sided hemostasis on the leg or arm, the range of pressure hemostasis required is small. When the triangular hinge plate 77 is folded to overlap with the surface of the hollow concave panel 71, the pressure hemostasis area is the same as the area of ​​the hollow concave panel 71. The triangular hinge plate 77 is fixed to the insertion support 79 by the fixing kit 710.

[0072] When the hemostasis device is used on a hemostasis vest for the waist, abdomen, chest and back, the range of pressure hemostasis required is large. When the triangular hinge plate 77 is folded to be flush with the surface of the hollow concave panel 71, the pressure hemostasis area is the sum of the areas of the hollow concave panel 71 and the triangular hinge plate 77, thereby realizing adjustable pressure hemostasis.

[0073] In addition, when two similar bleeding points appear on the leg or arm, the triangular hinge plate 77 can be used to increase the hemostasis area, thereby adapting to various hemostasis needs.

[0074] One of the four corners of the hollow concave panel 71 is provided with an elastic rope 9. At the same corner, there is a fixed protrusion 14 parallel to the elastic rope 9. The elastic rope 9 passes through the four sides of the hollow concave panel 71 and the end of the elastic rope 9 is fixed on the fixed protrusion 14. The elastic rope 9 is located between the shaping rod 73 and the triangular hinge plate 77.

[0075] The hollow concave panel 71 has limiting grooves 15 on its four sides for the elastic cord 9 to be tightly covered. The elastic cord 9 is used to divide the rubber airbag 72 along the four sides of the hollow concave panel 71 to prevent the filled gas from entering the rubber airbag 72 of the triangular hinge plate 77.

[0076] When using a small-area compression airbag, the elastic cord 9 can be used to seal the four sides of the rubber airbag 72 on the hollow concave panel 71, so that when inflated, the gas accumulates in the rubber airbag 72 to achieve the operation of compression to stop bleeding at the bleeding site.

[0077] like Figure 5 As shown, the function of the rubber airbag 72 is to squeeze the single-sided wearable cloth 1 so that its interior is tightly pressed against the bleeding site, thereby achieving hemostasis. The single-sided wearable cloth 1 requires a disposable hemostatic cloth 12 inside. Therefore, when the hemostasis equipment is in short supply, the single-sided wearable cloth 1 only needs to replace the disposable hemostatic cloth 12 inside and can continue to be used.

[0078] The single-sided wearable fabric 1 is made of non-elastic nylon fabric. The side of the single-sided wearable fabric 1 has a slit hole 10 between two nylon strips 6. A button 11 is provided on one side of the slit hole 10. The inner surface of the single-sided wearable fabric 1 is provided with a disposable hemostatic cloth 12. The edge of the disposable hemostatic cloth 12 is provided with a hook edge 13. The disposable hemostatic cloth 12 is fixed to the button 11 by the hook edge 13.

[0079] The disposable hemostatic cloth 12 can be passed through the opening 10 of the single-sided wearable cloth 1 via the hook edge 13 and then fastened to the button 11. In this way, the surface of the disposable hemostatic cloth 12 is flat, and hemostasis can be achieved by pressing the bleeding site under the action of the airbag.

[0080] Meanwhile, the blood overflowing from the wound can be absorbed by the disposable hemostatic cloth, and the blood will not seep through the disposable hemostatic cloth to the single-sided dressing cloth 1. The single-sided dressing cloth 1 always remains clean. Therefore, when the single-sided dressing cloth 1 needs to be reused, only the disposable hemostatic cloth 12 needs to be replaced for use by other patients.

[0081] Therefore, the hemostatic device of this embodiment can not only be used as a vest to stop bleeding in the chest, abdomen and back of the human body, but it can also be disassembled and used separately. It can be split in two at the shoulder, and the two strips can be used independently to stop bleeding in the limbs, head and neck of the human body. This achieves multiple uses with one device. For outdoor first aid activities, one hemostatic device can be used to treat different parts of the human body, thereby improving the efficiency of emergency treatment.

[0082] In addition, this embodiment provides a detachable airbag on the outer layer of the hemostasis device. The position of the airbag can be used for targeted and precise compression hemostasis according to the location of the injury. The optimal curved position of the inflated airbag is aligned with the injury location, thereby improving the effectiveness of hemostasis.

[0083] 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.
