And when the locking switch 14 is in the locking state, a portion of the external thread (the first adjusting unit 122) on the outer sidewall of the pushing body 120 and a portion of the internal thread (the second adjusting unit 112) on the inner sidewall of the through passage 111 are in contact with each other, so that the internal thread and the external thread of the contact portion are engaged with each other, that is, the first adjusting unit 122 and the second adjusting unit 112 are in a fitting state, in which, the pushing body 120 can be slowly moved with a small amplitude with respect to the locking body 110 in a stressed state, for example, the pressing force of the pushing tip 121 on the wound hole can be finely adjusted by applying a force to the pushing body 120 (e.g., rotating the operating end 123 of the pushing body 120 in a clockwise direction or a counterclockwise direction) to slowly move the pushing body 120 relative to the locking body 110 in a direction approaching the wound or in a direction away from the wound. In addition, the pushing body 120 can be positioned relative to the locking body 110 in an unstressed state, that is, when the pushing body 120 is not subjected to any external force, the pushing body 120 is positioned on the locking body 110, so as to maintain the pressing force of the pushing end 121 pressing on the wound hole.

Referring to fig. 3, fig. 4A and fig. 4B, in an embodiment of the present application, the locking body 110 further includes a locking outer shell 113 and a locking inner shell 114, wherein the locking inner shell 114 is sleeved in the locking outer shell 113, the through passage 111 is formed inside the locking inner shell 114, the second adjusting unit 112 is disposed on an inner sidewall of the through passage 111, and the locking inner shell 114 further has a through unit 115 penetrating through the sidewall thereof.

And the locking switch 14 is extended from the locking outer case 113 to the inside of the through passage 111 through the through unit 115 of the locking inner case 114. Specifically, as shown in fig. 3, the two opposite sides of the locking switch 14 are respectively provided with a first pivot portion 141 and a second pivot portion 142 which are respectively pivoted to the locking outer shell 113 and the locking inner shell 114, so that when the locking outer shell 113 rotates relative to the locking inner shell 114, the locking switch 14 is linked therewith. In addition, in the embodiment, the locking inner casing 114 is further provided with an operating portion 1141, and the locking inner casing 114 can move relative to the locking outer casing 113 by shifting the operating portion 1141 on the locking inner casing 114. It should be noted that the installation position of the operation portion 1141 is not limited to the drawings, and in other embodiments, the operation portion may be installed on the lock housing 113.

Specifically, please refer to fig. 4A and 4B, wherein fig. 4A is a schematic diagram illustrating the locking switch 14 in the non-locking state, and fig. 4B is a schematic diagram illustrating the locking switch 14 in the locking state. As shown in fig. 4A, when the locking outer shell 113 is at an initial position relative to the locking inner shell 114, the locking switch 14 is in a non-locking state, in which the locking switch 14 does not generate an abutting force on the pushing body 120, so that the first adjusting unit 122 of the pushing body 120 and the second adjusting unit 112 of the locking body 110 are in a non-fitting state, and therefore, the pushing body 120 can rapidly move relative to the locking body 110. By turning the operating portion 1141 (e.g., turning the operating portion 1141 clockwise in the drawings), the lock housing 113 is rotated relative to the lock housing 114 from an initial position to a locked position (i.e., from the state of fig. 4A to the state of fig. 4B), so that the lock switch 14 is switched from the unlocked state to the locked state, in which the portion of the lock switch 14 extending to the through channel 111 generates an abutting force against the pushing body 120 located in the through channel 111, so that the pushing body 120 abuts against the lock body 110, and the first adjusting unit 122 of the pushing body 120 and the second adjusting unit 112 of the lock body 110 are engaged with each other to be in an adapted state, thereby providing that the pushing body 120 can be slowly moved or positioned relative to the lock body 110 by a small amplitude.

In addition, the locking outer shell 113 can be rotated from the locking position to the initial position relative to the locking inner shell 114 by reversely toggling the operating portion 1141 (for example, toggling the operating portion 1141 in the counterclockwise direction in the drawing), so that the locking switch 14 is switched from the locking state to the unlocking state (i.e., switched from the state of fig. 4B to the state of fig. 4A), in which the abutting force of the locking switch 14 against the pushing body 120 is released, so that the first adjusting unit 122 of the pushing body 120 and the second adjusting unit 112 of the locking body 110 are switched from the adapting state to the non-adapting state.

Referring to fig. 2, in another embodiment, a hand-held portion 1131 may be further disposed on the locking housing 113, and is used for an operator to hold the locking housing for performing the above-mentioned various operations. In the embodiment, the handheld portion 1131 is, for example, a pair of wing portions extending from two opposite sides of the locking housing 113, but not limited thereto, and other configurations of the handheld portion 1131 may also be applied to the present application.

Referring to fig. 2 and fig. 3, in another embodiment, the locking device 11 further includes a base plate 116 disposed between the locking body 110 and the object, wherein a through hole 117 is further disposed on the base plate 116, and is located between the exit end 111b of the locking body 110 and the wound, for providing the pushing end 121 of the pushing body 120 to extend from the exit end 111b of the locking body 110 and penetrate through the through hole 117 of the base plate 116 to be pressed against the wound of the object. In one embodiment, the substrate 116 is made of an elastic material, and the substrate 116 has an arc-shaped surface matching with the surface of the object, so that the substrate 116 can be well attached to the surface of the object.

Further, in light of the above, the hemostatic structure 1 of the present application is particularly useful for hemostasis of wounds to a subject by a firearm or sharp, and in general, such wounds include wounds that extend from a wound on a surface of the subject to a wound tract within the body of the subject, in addition to wounds formed on the surface of the subject. The wound formed in the body of the object may be perpendicular to the surface of the object or may not be perpendicular to the surface of the object, and therefore, in another embodiment of the present application, the locking device 11 further includes an angle adjustment member 118.

Referring to fig. 2, fig. 3, fig. 5A and fig. 5B, in the present embodiment, an angle adjusting element 118 is further disposed between the locking body 110 and the base plate 116, for adjusting the setting angle between the locking body 110 and the base plate 116, so that the pushing end 121 of the pushing body 120 is always pressed on the wound along the axial direction of the wound. Specifically, the substrate 116 is attached and fixed on the surface of the object, the through channel 111 is formed inside the locking body 110 along the axial direction of the locking body 110, the angle adjusting member 118 is, for example, a flexible connecting member with certain elasticity, and the angle between the locking body 110 and the substrate 116 can be adjusted by using the angle adjusting member 118 to adjust the angle between the pushing direction of the pushing device 12 and the substrate 116 (i.e., the surface of the object), so that the pushing device 12 can be pressed on the wound at a certain angle, thereby achieving the purpose of always pressing the wound formed on the surface of the object along the axial direction of the wound (as shown in fig. 5A and 5B), so as to adapt to the formation condition of the actual wound, and thereby effectively improving the hemostatic effect of the wound. It should be noted that the angle adjusting element 118 of the present application can be implemented by using a mechanical structure component such as a cardan shaft, besides the flexible connecting element described above, but not limited thereto, and other components that can be used to arbitrarily adjust the positioning angle between the locking body 110 and the base plate 116 can be applied to the present application.

Referring to fig. 6A, fig. 6B, fig. 7A, and fig. 7B, in another embodiment, two connecting units 1161A, 1161B are further disposed on two opposite sides of the substrate 116, as shown in fig. 6A, in this embodiment, the connecting units 1161A, 1161B are respectively formed on two sides of the substrate 116, and the hemostatic structure 1 further includes a tourniquet 13 movably disposed in the two connecting units 1161 on two sides of the substrate 116 and wound on the object, so as to fix the locking device 11 on the object. Meanwhile, the tourniquet 13 is further provided with a hemostasis unit 131 for covering the wound hole formed on the surface of the object to perform primary hemostasis for the wound hole, and correspondingly, the pushing end 121 of the pushing device 12 pushes the hemostasis unit 131 to enable the hemostasis unit 131 to be tightly pressed on the wound hole to perform hemostasis.

As shown in fig. 7A, in an embodiment, a plurality of hemostatic units 131 are disposed on the tourniquet 13, and each hemostatic unit 131 may be disposed on the tourniquet 13 at equal intervals, for example, and the tourniquet 13 has a certain elasticity so as to adapt to the binding and fixing operations of objects with different shapes.

Referring to fig. 8A to 8D, in another embodiment, a flexible pressing sheet 132 may be further disposed on the hemostatic unit 131, wherein a flange 1321 is formed on the flexible pressing sheet 132, so that the hemostatic unit 131 can be deformed according to the specific shape of the wound after being pushed and pressed by the pushing tip 121 to be pressed on the wound in a sealing manner, thereby achieving a better hemostatic effect.

When the hemostatic structure 1 provided in the first embodiment of the present application is used to perform a hemostatic operation, the tourniquet 13 may be wound around the object, and one hemostatic unit 131 on the tourniquet 13 covers a wound on the surface of the object. Then, one exposed end of the tourniquet 13 is passed through the connecting unit 1161A (as shown in fig. 7B) on one side of the substrate 116 of the locking device 11, and is wound around the subject along the direction indicated by the arrow shown in fig. 6B, and then passed through the connecting unit 1161B on the other side of the substrate 116, and then the end of the tourniquet 13 is fixedly connected to the body of the tourniquet 13, for example, in an adhesive manner, so as to fix the locking device 11 on the subject.

After the locking device 11 is fixed, the locking switch 14 may be switched to the non-locking state to rapidly and largely move the pushing body 120 relative to the locking body 110, so that the pushing end 121 approaches the position of the wound rapidly, and after the pushing end 121 is slightly pressed on the wound, the locking switch 14 may be switched from the non-locking state to the locking state, and by applying an acting force to the operation end 123 of the pushing body 120, the pushing body 120 is slowly and largely moved relative to the locking body 110, so as to finely adjust the pressing force of the pushing end 121 pressed on the wound; then, the force applied to the operation end 123 can be released, so that the pushing body 120 is positioned relative to the locking body 110 in the locked state, thereby maintaining the pressing force of the pushing end 121 pressing on the wound, thereby stopping bleeding on the wound on the object.

In addition, the present application also provides a hemostatic structure 1 of a second embodiment for hemostasis of a wound, the wound of the present embodiment including a wound hole formed in a surface of the subject and a wound tract extending from the wound hole into the body of the subject. The wound formed in the body of the object may be perpendicular to the surface of the object or may not be perpendicular to the surface of the object.

The hemostatic structure 1 of the present embodiment mainly comprises a locking device 11 and an ejector 12, wherein the locking device 11 is fixed on an object and has a locking body 110, a base plate 116, and an angle adjuster 118.

Specifically, a through passage 111 is formed inside the locking body 110, and the through passage 111 further has an outlet end 111b, which is formed, for example, on the bottom surface of the locking body 110. The substrate 116 is disposed between the locking body 110 and the object, and a through hole 117 (as shown in fig. 3) is further disposed on the substrate 116, and the through hole 117 is located between the outlet end 111b of the locking body 110 and the wound hole. The angle adjuster 118 is disposed between the locking body 110 and the base plate 116, and is used for adjusting a positioning angle between the locking body 110 and the base plate 116.

The pushing device 12 is disposed in the through channel 111 of the locking body 110 and is movable relative to the locking body 110, and the pushing device 12 further has a pushing end 121, which can extend from the outlet end 111b of the locking body 110 and press against the wound through the through hole 117 of the base plate 116 to perform compression hemostasis, and in the process of compression hemostasis, the positioning angle between the locking body 110 and the base plate 116 can be adjusted by the angle adjusting member 118, so that the pushing end 121 of the pushing device 12 can always press against the wound along the axial direction of the wound, so as to adapt to the formation condition of the actual wound, thereby effectively improving the hemostasis effect of the wound. The angle adjusting element 118 may be, for example, a flexible connecting element, or may be implemented by using a mechanical component such as a universal shaft, but not limited thereto, and other components that can be used to arbitrarily adjust the positioning angle between the locking body 110 and the base plate 116 may be suitable for the present application.

In addition, in another embodiment, the locking device 11 can be switched between a locking state and a non-locking state, and specifically, when the locking device 11 is in the non-locking state, the ejector 12 can be provided to move rapidly and greatly relative to the locking device 11; when the locking device 11 is in the locking state, the pushing device 12 can be positioned relative to the locking device 11 without being subjected to an external force, so as to maintain the pressing force of the pushing end 121 on the wound hole, and in addition, the pushing device 12 can be slowly moved with a small amplitude relative to the locking device 11 under the action of the external force, so as to finely adjust the pressing force of the pushing end 121 on the wound hole.

Specifically, the pushing device 12 further includes a pushing body 120 and a first adjusting unit 122, wherein the pushing end 121 is disposed at one end of the pushing body 120, and further, an operating end 123 is disposed at the other end of the pushing body 120 for providing an applying force.

Furthermore, the locking device 11 further includes a second adjusting unit 112 and a locking switch 14, wherein the second adjusting unit 112 is disposed on the through passage 111, and the second adjusting unit 112 can be matched with the first adjusting unit 122 to switch between an adaptive state and a non-adaptive state. In the embodiment, the second adjusting unit 112 is an internal thread (as shown in fig. 3) disposed on the inner sidewall of the through channel 111, so that when the first adjusting unit 122 and the second adjusting unit 112 are in the fitting state, the pushing body 120 can be moved relative to the locking body 110 by rotating the pushing body 120 relative to the locking body 110. The locking switch 14 is disposed on the locking body 110, and when the locking switch 14 is in the non-locking state, the first adjusting unit 122 and the second adjusting unit 112 are in the non-adaptive state, so that the pushing body 120 can rapidly and substantially move relative to the locking body 110; when the locking switch 14 is in the locking state, the first adjusting unit 122 and the second adjusting unit 112 are in the fitting state, in which the pushing body 120 can be positioned relative to the locking body 110 in the non-stressed state, or can be slowly moved with a small amplitude relative to the locking body 110 in the stressed state, so as to finely adjust the pressing force of the pushing head 121 pressing on the wound hole.
