[0001] This application relates to tourniquets, and more particularly, to tourniquets having a multi-angle compression device. [Background technology]

[0002] Traditionally, humans have discovered that binding an amputated limb with a belt and applying pressure with a rotating rod can effectively reduce blood loss. Summary of the Invention [Problem to be solved by the invention]

[0003] However, most tourniquets in the known art are equipped with only a single compression device, such as a rod member, a ratchet, or a buckle, etc. However, when using the compression device, it is difficult to ensure reliable compression because the thickness of the limb to be compressed varies, and the compression force is likely to be insufficient.

[0004] In addition, modern tactical first aid requires that when a tourniquet is operated by a single person, all steps of applying pressure to the limb must be completed within 15 seconds to prevent excessive bleeding. However, as described above, conventional tourniquets have the above problems, so when operated by a single person, it is difficult to complete the bleeding control steps within the time limit, and problems occur frequently. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] In order to allow the examiner to understand the technical features, contents, advantages and effects that can be achieved by the present application, the embodiments of the present application will be described in detail with accompanying drawings. In addition, the drawings used in the present application are for illustrating and assisting the description, and do not necessarily represent the actual proportions and precise configurations after the implementation of the present application, so that the proportions and configuration relationships of the accompanying drawings should not be interpreted as limiting the scope of rights in the actual implementation of the present application.

[0017] Hereinafter, embodiments of the present application will be described with reference to the related drawings. In order to facilitate understanding, the same elements in the following embodiments will be denoted by the same reference numerals.

[0018] 1 to 8, which respectively show a first top view, first and second cross-sectional views, first to fourth schematic views of a tourniquet having a multi-angle compression device according to the present application, a schematic view of a first compression device, and a schematic view of a fixing element.

[0019] The tourniquet with multi-angle compression device according to the present application includes a tourniquet body 11, a first compression device 12, and a fixing element 14. The first compression device 12 is rotatably disposed on the tourniquet body 11 and includes at least three columnar structures. Each columnar structure extends outward from a rotation center of the first compression device 12. A first width W1 is defined between the columnar structures. The fixing element 14 is disposed adjacent to the first compression device 12 and disposed on the tourniquet body.

[0020] As shown in Fig. 2(a) to (c), the number of columnar structures may be three, four, six, etc. Also, the number of columnar structures may be any number, such as five, six or more. To explain further, as shown in Figs. 2 and 3, in order to prevent mutual interference between the first compression device 12 and the fixing element 14, the first width W1 is larger than the second width W2 of the fixing element 14. Also, the position defined by the first width W1 is determined by the length of the columnar structures and the position of the fixing element 14.

[0021] The distance from the center of rotation of the first compression device 12 to the fixing element 14 is less than the extension length of any of the columnar structures from the center of rotation. In other words, one must ensure that the length of the columnar structures extends sufficiently to the fixing element 14 so that the fixing element 14 can fix the position of the first compression device 12.

[0022] In one embodiment, a first buckle 151 and a second buckle 152 can be provided penetrating the tourniquet body 11, thereby allowing the length of the tourniquet body 11 to be adjusted and the position of the tourniquet body 11 to be regulated. When bleeding needs to be stopped, the tourniquet body 11 is first wrapped around the limb to be stopped, and the first compression device 12 compresses the tourniquet body 11 so that the tourniquet body 11 can further compress the limb.

[0023] To further explain, take the first compression device 12 as an example, which includes three columnar structures, when the first compression device 12 rotates, the position of the first compression device 12 can be fixed by the fixing element 14 every time the first compression device 12 rotates up to 120 degrees.

[0024] Similarly, if the first compression device 12 includes four columnar structures, as the first compression device 12 rotates, the position of the first compression device 12 may be fixed by the fixing element 14 after each rotation of up to 90 degrees.

[0025] Similarly, if the first compression device 12 includes six columnar structures, when the first compression device 12 rotates, the position of the first compression device 12 can be fixed by the fixing element 14 every time the first compression device 12 rotates up to 60 degrees. Therefore, the present invention can be applied to users of various body types.

[0026] Furthermore, the fixing element 14 includes at least one position regulating unit 143, a first curved portion 141 and a second curved portion 142. The at least one position regulating unit 143 may be disposed between the first curved portion 141 and the second curved portion 142. The first curved portion 141 forms a first groove, and the second curved portion 142 forms a second groove, and the recessed directions of the first groove and the second groove are opposite to each other.

[0027] Therefore, when the first compression device 12 is rotated, the second compression belt 112 moves toward the upper surface of the covering layer 114 so that the tourniquet body 11 contracts and applies pressure to the limb. In addition, in one embodiment, the first compression device 12 can include an aluminum alloy to make the first compression device 12 less likely to be damaged.

[0028] As shown in FIGS. 5 to 7, in order to fix the first compression device 12 and the second compression device 13, the first compression device 12 may be brought into contact with either the first bending portion 141 or the second bending portion 142. As shown in FIG.

[0029] 6, in one embodiment, the position regulating unit 143 of the present application may be disposed between the first curved portion 141 and the second curved portion 142. For example, it may be disposed in the center of the fixed element 14. The position regulating unit 143 may be made of an elastic material such as polypropylene (PP). The first and second distances G1 and G2 between the tips of the side walls of the first and second curved portions 141 and 142 are smaller than the thickness D1 of the first and second compression devices 12 and 13.

[0030] Therefore, after the first compression device 12 passes through the first bending portion 141 or the second bending portion 142 and the position restriction unit 143 , the position of the first compression device 12 is restricted to the first bending portion 141 or the second bending portion 142 .

[0031] Furthermore, the upper part of the position control unit 143 may be a three-dimensional structure having a smooth curved surface such as a hemisphere or an ellipsoid, and the tips of the side walls of the first curved portion 141 and the second curved portion 142 may be rounded or chamfered so that the first compression device 12 and the second compression device 13 can slide through.

[0032] 7, in another embodiment, the position regulating unit 143 of the present application may be disposed at other positions, for example, two position regulating units 143 may be disposed at the tips of the side walls of the first curved portion 141 and the second curved portion 142, respectively, adjacent to the bottom of the fixed element 14. The position regulating unit 143 may be made of an elastic material such as polypropylene (PP). The first and second distances G1 and G2 between the tips of the side walls of the first and second curved portions 141 and 142 are smaller than the thickness D1 of the first and second compression devices 12 and 13.

[0033] In one embodiment, as shown in Fig. 8, the tourniquet body 11 may include a first pressure belt 111, a second pressure belt 112, and a covering layer 114. As shown in Fig. 8, a first portion and a second portion of the second pressure belt 112 may be connected to the first pressure belt 111, and a third portion of the second pressure belt 112 may be movably disposed on the first pressure belt 111. The covering layer 114 may cover the first pressure belt 111 and the second pressure belt 112. The first compression device 12 is connected to the third portion of the second pressure belt 112 through an opening in the covering layer 114.

[0034] Specifically, the first and second portions of the second pressure belt 112 may be located at both ends of the first pressure belt 111, respectively. The first portion of the second pressure belt 112 may be sewn to the first pressure belt 111, and the second portion of the second pressure belt 112 and one end of the first pressure belt 111 may be connected to the first buckle 151.

[0035] To explain further, in this embodiment, the first distance G1 and the second distance G2 between the position regulating unit 143 and the tips of the side walls of the first bending portion 141 and the second bending portion 142 are smaller than the thickness D1 of the first compression device 12. Therefore, similar to the embodiment in which the position regulating unit 143 is disposed in the center of the fixed element 14, the position of the first compression device 12 can be regulated to the first bending portion 141 and the second bending portion 142.

[0036] Similarly, in this embodiment, the upper part of the position control unit 143 may be a three-dimensional structure having a smooth curved surface such as a hemisphere or an ellipsoid, and the tips of the side walls of the first curved portion 141 and the second curved portion 142 may be rounded or chamfered so that the first compression device 12 and the second compression device 13 can slide through.

[0037] In addition to the above embodiment including the second compression belt 112, the present application may have other embodiments. As shown in FIG. 4, the tourniquet with the multi-angle compression device of the present application may not include the second compression belt 112 and the third compression belt 113. Specifically, the first compression device 12 may be directly disposed on the first compression belt 111. As shown in FIG. 4, if the first compression device 12 includes a columnar structure, it is necessary to provide a fixing element 14. If the first compression device 12 is a ratchet or other compression device that can fix its position, it is not necessary to provide a fixing element 14.

[0038] In addition to the above-mentioned embodiment, in order to realize the function of multi-angle compression, as shown in Figures 9 to 16, the tourniquet with multi-angle compression device of the present invention can further include a second compression device 13. The second compression device 13 corresponds to the first compression device 12 and is disposed on the tourniquet body 11. The fixing element 14 is disposed between the first compression device 12 and the second compression device 13.

[0039] In one embodiment, as shown in Figures 9 and 10, since it has a second compression device 13, the first compression device 12 may include at least two columnar structures and be formed into a rod member, and the second compression device 13 may also be a rod member.

[0040] In one embodiment, first, the tourniquet body 11 is wrapped around the limb to be stopped, and then the tourniquet body 11 is contracted by the first compression device 12 so that the tourniquet body 11 further presses the limb. Then, the first compression device 12 is fixed by the fixing element 14. Also, since there are individual differences in the size of the limb, the force with which the first compression device 12 presses the limb after being fixed by the fixing element 14 may be insufficient. In this case, the tourniquet body 11 is further contracted by the second compression device 13 so that the tourniquet body 11 further presses the limb, thereby achieving the effect of multi-angle compression.

[0041] In this embodiment, the first compression device 12 can include at least three or more columnar structures (for example, the first compression device 12 in FIG. 9 includes four columnar structures), so that the user can apply pressure to the limb using only the first compression device 12, and can decide whether to use the second compression device 13 as needed.

[0042] In one embodiment, the tourniquet body 11 may include a first pressure belt 111, a second pressure belt 112, and a covering layer 114. As shown in Fig. 11, a first portion and a second portion of the second pressure belt 112 may be connected to the first pressure belt 111, and a third portion of the second pressure belt 112 may be movably disposed on the first pressure belt 111. The covering layer 114 may cover the first pressure belt 111 and the second pressure belt 112. The first compression device 12 and the second compression device 13 are connected to the third portion of the second pressure belt 112 through the openings of the covering layer 114.

[0043] To further explain, a first portion of the second pressure belt 112 may be sewn to the first pressure belt 111, and one end of the first pressure belt 111 and a second portion of the second pressure belt 112 may be connected to the first buckle 151. A third portion of the second pressure belt 112 is not sewn to the first pressure belt 111, and may be movably disposed on the first pressure belt 111.

[0044] Furthermore, the fixing element 14 includes at least one position regulating unit 143, a first curved portion 141, and a second curved portion 142. The at least one position regulating unit 143 may be disposed between the first curved portion 141 and the second curved portion 142. The first curved portion 141 forms a first groove, and the second curved portion 142 forms a second groove, and the recessed directions of the first groove and the second groove are opposite to each other.

[0045] Therefore, when the first compression device 12 and the second compression device 13 are rod members, when the first compression device 12 and the second compression device 13 are rotated, the second compression belt 112 moves toward the upper surface of the covering layer 114 so that the tourniquet body 11 contracts and applies pressure to the limb. In addition, in one embodiment, the first compression device 12 and the second compression device 13 can include an aluminum alloy to make them less susceptible to damage.

[0046] 13 or 14, in order to fix the first compression device 12 and the second compression device 13, the first compression device 12 can be brought into contact with one of the first bending portion 141 or the second bending portion 142, and the second compression device 13 can be brought into contact with the other of the first bending portion 141 or the second bending portion 142. With this configuration, even if the first compression device 12 comes into contact with the first bending portion 141 or the second bending portion 142 and the pressurizing force is insufficient, secondary pressurization can be performed using the second compression device 13, thereby completing the process of pressurized hemostasis.

[0047] 13 and 14, in one embodiment, the position regulating unit 143 of the present application can be disposed between the first curved portion 141 and the second curved portion 142, for example, disposed in the center of the fixed element 14. The position regulating unit 143 may be made of an elastic material such as polypropylene (PP). The first and second distances G1 and G2 between the tips of the side walls of the first and second curved portions 141 and 142 are smaller than the thickness D1 of the first and second compression devices 12 and 13.

[0048] Therefore, after the first compression device 12 passes through the first bending portion 141 or the second bending portion 142 and the position regulating unit 143, the position of the first compression device 12 is regulated to the first bending portion 141 or the second bending portion 142. Similarly, after the second compression device 13 passes through the first bending portion 141 or the second bending portion 142 and the position regulating unit 143, the position of the second compression device 13 is regulated to the first bending portion 141 or the second bending portion 142.

[0049] Furthermore, the upper part of the position control unit 143 may be a three-dimensional structure having a smooth curved surface such as a hemisphere or an ellipsoid, and the tips of the side walls of the first curved portion 141 and the second curved portion 142 may be rounded or chamfered so that the first compression device 12 and the second compression device 13 can slide through.

[0050] 14, in another embodiment, the position regulating unit 143 of the present application may be disposed at other positions, for example, two position regulating units 143 may be disposed at the tips of the side walls of the first curved portion 141 and the second curved portion 142, respectively, adjacent to the bottom of the fixed element 14. The position regulating unit 143 may be made of an elastic material such as polypropylene (PP). The first and second distances G1 and G2 between the tips of the side walls of the first and second curved portions 141 and 142 are smaller than the thickness D1 of the first and second compression devices 12 and 13.

[0051] To explain further, in this embodiment, the first distance G1 and the second distance G2 between the position regulating unit 143 and the tips of the side walls of the first bending portion 141 and the second bending portion 142 are smaller than the thickness D1 of the first compression device 12 and the second compression device 13. Therefore, similar to the embodiment in which the position regulating unit 143 is disposed in the center of the fixed element 14, the first compression device 12 and the second compression device 13 can be positioned at the first bending portion 141 and the second bending portion 142.

[0052] Similarly, in this embodiment, the upper part of the position control unit 143 may be a three-dimensional structure having a smooth curved surface such as a hemisphere or an ellipsoid, and the tips of the side walls of the first curved portion 141 and the second curved portion 142 may be rounded or chamfered so that the first compression device 12 and the second compression device 13 can slide through.

[0053] 15 to 17, the first compression device 12 and the second compression device 13 may be rod members including a columnar structure, or may be other configurations. Any configuration in which multiple compression devices contract the tourniquet body 11 so that the tourniquet body 11 can apply pressure to the limb multiple times should be considered as within the inventive concept of the present application.

[0054] In one embodiment, as shown in Fig. 15, the first compression device 12 may be a rod member, and the second compression device 13 may be a ratchet or other compression device that can fix its position. In one embodiment, as shown in Fig. 16, the first compression device 12 may be a ratchet or other compression device that can fix its position, and the second compression device may be a rod member. In one embodiment, as shown in Fig. 17, the first compression device 12 may be a ratchet or other compression device that can fix its position, and the second compression device 13 may also be a ratchet or other compression device that can fix its position.

[0055] As a different embodiment of the tourniquet having a multi-angle compression device according to Figs. 15-16 of the present application, the tourniquet body 11 may have the structure shown in Figs. 11-14. For example, the tourniquet body 11 may include a first compression belt 111, a second compression belt 112 and a covering layer 114, and the first curved portion 141 and the second curved portion 142 may be formed on the fixing element 14. To explain further, since Figs. 15 and 16 have only one rod member, after the tourniquet body 11 contracts and presses the limb, only one rod member is positioned at the first curved portion 141 or the second curved portion 142. The above structure may be referred to for related explanations, and the explanations will be omitted here.

[0056] 17, the tourniquet with multi-angle compression device includes a tourniquet body 11, a first compression device 12 and a second compression device 13. The first compression device 12 may be disposed in the tourniquet body 11. The second compression device 13 corresponds to the first compression device 12 and is disposed in the tourniquet body 11.

[0057] To further explain, the first compression device 12 may be a ratchet or other compression device capable of fixing its own position, and the second compression device 13 may also be a ratchet or other compression device capable of fixing its own position. When the first compression device 12 and the second compression device 13 are both ratchet or other compression devices capable of fixing their own positions, the above-mentioned fixing effect and the effect of compressing the limb multiple times by the tourniquet body 11 can be obtained without further adding a fixing element 14.

[0058] In addition, the tourniquet with the multi-angle compression device according to Fig. 17 can have the structure of Fig. 9. Specifically, the tourniquet body 11 can include a first compression belt 111, a second compression belt 112 and a covering layer 114. To further explain, the structure disclosed in Fig. 17 does not have a rod member, and therefore there is no need to further add a fixing element 14.

[0059] In one embodiment, as shown in Figures 17 and 9, the tourniquet body 11 may include a first pressure belt 111, a second pressure belt 112, and a covering layer 114. As shown in Figure 18, a first portion and a second portion of the second pressure belt 112 may be connected to the first pressure belt 111, and a third portion of the second pressure belt 112 may be movably disposed on the first pressure belt 111. The covering layer 114 may cover the first pressure belt 111 and the second pressure belt 112. The first compression device 12 and the second compression device 13 are connected to the third portion of the second pressure belt 112 through the openings in the covering layer 114.

[0060] To further explain, the first and second portions of the second pressure belt 112 may be sewn to the first pressure belt 111, and the third portion of the second pressure belt 112 is not sewn to the first pressure belt 111 and may therefore be movably positioned on the first pressure belt 111.

[0061] Therefore, when the first compression device 12 and the second compression device 13 are rod members, when the first compression device 12 and the second compression device 13 are rotated, the second compression belt 112 moves toward the upper surface of the covering layer 114 so that the tourniquet body 11 shrinks and applies pressure to the limb.

[0062] In addition to the structures disclosed above, in one embodiment, as shown in Figures 19 to 24, the tourniquet body 11 can include a third pressure belt 113.

The first compression device 12 and the second compression device 13 are connected to the third parts of the second pressure belt 112 and the third pressure belt 113 through the openings of the cover layer 114.

[0077] In addition, in this embodiment, the first compression device 12 and the second compression device 13 are ratchets or other compression devices that can fix their positions, so no fixing element 14 is added, and the relevant description can be referred to the above embodiment. In this embodiment, when the first compression device 12 and the second compression device 13 are rotated, the second compression belt 112 moves toward the upper surface of the covering layer 114, and the third compression belt 113 moves toward the upper surface of the covering layer 114, so that the tourniquet body 11 shrinks and applies pressure to the limb.

[0078] 17 and 22 to 24, the first compression device 12 may be a ratchet or other compression device capable of fixing its position, and the second compression device 13 may also be a ratchet or other compression device capable of fixing its position. The tourniquet body 11 may include a first compression belt 111, a second compression belt 112, a third compression belt 113 and a covering layer 114.

[0079] As shown in FIG. 24, the first and second parts of the second pressure belt 112 may be connected to the first pressure belt 111, and the third part of the second pressure belt 112 may be movably arranged on the first pressure belt 111.

The first compression device 12 is connected to the second pressure belt 112 and the third part of the third pressure belt 113 through an opening in the covering layer 114.

[0080] In addition, in this embodiment, the fixing element 14 is not added, and the relevant description can be referred to the above embodiment. In this embodiment, when the first compression device 12 and the second compression device 13 are rotated, the second compression belt 112 moves toward the upper surface of the covering layer 114, and the third compression belt 113 rolls up a part of the covering layer 114, so that the tourniquet body 11 shrinks and applies pressure to the limb.

[0081] In addition to the above embodiment including the second pressure belt 112 and the third pressure belt 113, the present application may have other embodiments. As shown in FIG. 25 and FIG. 26, the tourniquet with the multi-angle compression device of the present application may not be provided with the second pressure belt 112 and the third pressure belt 113. Specifically, the first compression device 12 and the second compression device 13 may be sewn to the first compression belt 111. Also, the first compression device 12 and the second compression device 13 may be a rod member, a ratchet, or other compression device that can fix its own position. When at least one of the first compression device 12 and the second compression device 13 is a rod member, it is necessary to provide a fixing element 14 as shown in FIG. 16. When the first compression device 12 is a ratchet or other compression device that can fix its own position, and the second compression device 13 is also a ratchet or other compression device that can fix its own position, the fixing element 14 may not be provided.

[0082] More specifically, as shown in Figures 4, 8, 11 and 18 to 26, the first attachment structure 115 and the second attachment structure 116 can be disposed on the bottom and top surfaces, respectively, of the tourniquet body 11. Therefore, when the tourniquet body 11 is wrapped, the first attachment structure 115 and the second attachment structure 116 are attached to each other.

[0083] In one embodiment, the first attachment structure 115 and the second attachment structure 116 may include Velcro® or other reattachable elements. Thus, after wrapping the tourniquet body 11, the user first attaches the first attachment structure 115 and the second attachment structure 116 to each other, and then uses the first compression device 12 and the second compression device 13 to shrink the tourniquet body 11 and apply pressure to the limb. In this embodiment, the use of the first attachment structure 115 and the second attachment structure 116 makes the tourniquet body 11 easier to use and can shorten the emergency time.

[0084] 17, in addition to the above-mentioned structures, in one embodiment, the tourniquet with the multi-angle compression device of the present application may further include a third attachment structure 117. The third attachment structure 117 may be connected to the tourniquet body 11. The third attachment structure 117 is a band-like structure, one surface of which is an attachment surface, and may be Velcro (registered trademark) or other reattachable elements.

[0085] When the tourniquet body 11 is wrapped, the third attachment structure 117 can be attached to the first attachment structure 115 or the second attachment structure 116. The other surface of the third attachment structure 117 is a writing surface. To prevent secondary injuries caused by prolonged pressure on the limb, the user can write the time the tourniquet body 11 was wrapped on the writing surface of the third attachment structure 117.

[0086] In one embodiment, either or both of the first attachment structure 115 or the second attachment structure 116 can be omitted, and only the third attachment structure 117 can be used to fix the tourniquet body 11 after it has been wrapped.

[0087] In summary, the tourniquet with the multi-angle compression device of the present application has various embodiments. The tourniquet with the multi-angle compression device of the present application can apply pressure to the limb from multiple angles, which solves the problem that the limb has different thicknesses and therefore cannot perform reliable compression hemostasis. The present application can improve the efficiency of use of the tourniquet, making it easier to use the tourniquet. Furthermore, by having one or more compression devices, the reliability of the tourniquet with the multi-angle compression device of the present application can be improved, and it can be prevented that the tourniquet becomes unusable due to the failure of any of the compression devices.

[0088] The above description is merely illustrative and is in no way limiting. Any equivalent modifications or variations made without departing from the spirit and scope of the present application should be covered by the appended claims. [Explanation of symbols]
