Description

Technical Field

[0001] This invention belongs to the field of outdoor rescue technology, specifically referring to a hemostatic device for emergency rescue in the wild. Background Technology

[0002] Outdoor emergency tourniquets are generally either twisted tourniquets or zip ties. Twisted tourniquets are the most commonly used because they are simple in structure and inexpensive, but there are still areas for improvement.

[0003] The rotating hemostatic belt has two stages of contraction. The first contraction is enough to fix the limb in place. The second contraction uses leverage to further bind the limb. Although this contraction can stop the bleeding by squeezing the limb, it is extremely painful for the patient. Although the patient may endure this pain for the sake of treatment, it is not necessary to endure it.

[0004] This application proposes a hemostatic device that provides similar efficacy to a spin-type tourniquet, but is easier to use and causes less pain.

[0005] To address the aforementioned problems, this invention proposes a hemostatic device for emergency rescue in the wild. Summary of the Invention

[0006] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a hemostatic device for emergency rescue in the wild and a method for using the device.

[0007] This invention provides a hemostatic device for emergency rescue in the wild, including a binding and fixing mechanism, a local pressing mechanism, and a rotating fixing mechanism. The local pressing mechanism is disposed in the binding and fixing mechanism, which can fix the device at the position where the wounded person needs to stop bleeding. The rotating fixing mechanism is rotatably disposed on the local pressing mechanism.

[0008] Furthermore, the binding and fixing mechanism includes a main hemostatic housing and a hemostatic band, wherein the hemostatic band is disposed on the main hemostatic housing.

[0009] Preferably, the main hemostatic housing has a square housing portion, with symmetrical housing wings at both ends of the square housing portion. The housing wings have through square housing grooves, and the inner wall of the square housing portion has a bottom recess. The housing wings have symmetrical housing side through grooves, and the housing wings also have symmetrical housing notches at both ends. The housing notches have housing cylinders, and the hemostatic bandage is fixed to the housing cylinders, so that the main hemostatic housing and the hemostatic bandage can be formed into a complete ring.

[0010] As a further preferred embodiment of the present invention, one end of the hemostatic bandage is provided with a bandage fixing buckle, and the hemostatic bandage is connected to the housing cylinder through the bandage fixing buckle. The other end of the hemostatic bandage is provided with a bandage free end, which is wrapped around the housing cylinder. The bandage free end is provided with Velcro. The main hemostatic housing and the hemostatic bandage form a complete ring, which can adapt to limbs of different diameters and can compress the bleeding arteries and veins through its own mobile mechanism, thereby stopping the bleeding.

[0011] Furthermore, the local pressing mechanism includes an elastic pressing plate and a pressing control stud. The elastic pressing plate is engaged in a groove at the bottom of the housing, and the pressing control stud is rotatably disposed in the elastic pressing plate.

[0012] Preferably, the elastic pressing pad is symmetrically provided with pressing pad fixing ends. The elastic pressing pad is engaged in the through groove on the side of the housing through the pressing pad fixing ends. The pressing pad fixing ends are fixedly connected to the housing wing. The elastic pressing pad is also provided with a pressing pad square boss. The pressing pad square boss is provided with a pressing pad threaded hole. The two ends of the elastic pressing pad are fixed to the main hemostatic housing. By the relative movement of the pressing pad square boss after the main hemostatic housing is fixed, the purpose of local pressing is achieved, and the purpose of blocking blood flow is achieved without tightening the whole circle.

[0013] As a further preferred embodiment of the present invention, the pressing control stud is provided with a stud threaded portion, which is threadedly connected to the pressing plate threaded hole. The pressing control stud is also provided with a stud polygonal portion. Through the threaded transmission between the pressing plate threaded hole and the stud polygonal portion, the rising and falling of the pressing plate square boss can be controlled when the pressing control stud rotates, thereby squeezing the bleeding arteries and veins and stopping the bleeding.

[0014] The positioning ring is fixed in the square groove of the housing, and the pressing control stud is rotated in the positioning ring. The positioning ring ensures that the pressing control stud can only rotate on its own axis and cannot move axially.

[0015] Furthermore, the rotating fixing mechanism includes a pressing control rod, a limiting component, and a control rod bracket. The pressing control rod is engaged and slidably mounted on the pressing control stud, the limiting component is located in the pressing control rod, and the control rod bracket is located on the square portion of the housing.

[0016] Preferably, the pressing control rod has a cylindrical part and a cantilever part. The cylindrical part of the control rod has a polygonal countersunk groove. The polygonal part of the stud is engaged and slidably disposed in the polygonal countersunk groove. The bottom of the polygonal countersunk groove has a circular countersunk groove. The limiting component is located in the circular countersunk groove. The cantilever part is symmetrically disposed on both sides of the cylindrical part of the control rod. The pressing control rod can slide along the polygonal part of the stud. When the pressing control rod is raised, it can disengage from the limiting position of the control rod bracket and rotate. Since the engagement between the polygonal part of the stud and the polygonal countersunk groove of the control rod is still maintained, the pressing control rod can still drive the pressing control stud to rotate when it rotates.

[0017] As a further preferred embodiment of the present invention, the limiting component includes an upper connecting piece, a lower connecting piece, and a limiting tension spring. The upper connecting piece is fixed to the bottom of the circular countersunk groove of the control rod, the lower connecting piece is fixed to the top of the polygonal portion of the stud, and the two ends of the limiting tension spring are respectively fixed to the upper connecting piece and the lower connecting piece. The limiting component can limit the maximum distance between the cylindrical portion of the control rod and the polygonal portion of the stud, and in a natural state, the cylindrical portion of the control rod and the polygonal portion of the stud tend to move closer to each other.

[0018] As a further preferred embodiment of the present invention, the control rod bracket includes a main fixing frame and a secondary fixing frame. The main fixing frame is symmetrically arranged on the square portion of the housing and is fixedly connected to the square portion of the housing. The main fixing frame is provided with a fixing frame slot one, and the cantilever rod portion is engaged in the fixing frame slot one. The secondary fixing frame is symmetrically arranged on the square portion of the housing and is provided with a fixing frame slot two, and the cantilever rod portion is engaged in the fixing frame slot two.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] (1) The device can be fixed to the location where the wounded need to stop bleeding by means of a binding and fixing mechanism;

[0021] (2) The hemostatic bandage is fixed on the cylindrical shell, which can form a complete ring by connecting the main hemostatic shell and the hemostatic bandage;

[0022] (3) The main hemostatic shell and the hemostatic bandage form a complete ring, which can adapt to limbs of different diameters and can compress the bleeding arteries and veins through its own mobile mechanism to stop bleeding;

[0023] (4) The two ends of the elastic pressing pad are fixed to the main hemostatic housing. After the main hemostatic housing is fixed, the relative movement of the square protrusion of the pressing pad is used to achieve the purpose of local pressing. The purpose of blocking blood flow is achieved without tightening the whole circle.

[0024] (5) Through the threaded transmission between the threaded hole of the pressing plate and the polygonal part of the stud, the rising and falling of the square boss of the pressing plate can be controlled when the pressing control stud is rotating, thereby squeezing the bleeding arteries and veins and stopping the bleeding.

[0025] (6) The positioning ring is fixed in the square groove of the housing, and the pressing control stud is rotated in the positioning ring. The positioning ring makes the pressing control stud only rotate and not move axially.

[0026] (7) The press control lever can slide along the polygonal part of the stud. When the press control lever is raised, it can be disengaged from the limit of the control lever bracket and rotate. Since the engagement between the polygonal part of the stud and the polygonal countersunk groove of the control lever is still maintained, the press control lever can still drive the press control stud to rotate when it rotates.

[0027] (8) The limit component can limit the maximum distance between the cylindrical part of the control lever and the polygonal part of the stud, and in the natural state, the cylindrical part of the control lever and the polygonal part of the stud tend to move closer to each other.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] like Figures 1-8 As shown, the present invention proposes a hemostatic device for emergency rescue in the wild, including a binding and fixing mechanism 1, a local pressing mechanism 2 and a rotating fixing mechanism 3. The local pressing mechanism 2 is disposed in the binding and fixing mechanism 1. Through the binding and fixing mechanism 1, the device can be fixed at the position where the wounded person needs to stop bleeding. The rotating fixing mechanism 3 is rotatably disposed on the local pressing mechanism 2.

[0041] The binding and fixing mechanism 1 includes a main hemostatic housing 4 and a hemostatic band 5, with the hemostatic band 5 disposed on the main hemostatic housing 4.

[0042] The main hemostatic housing 4 is provided with a square housing portion 6. The two ends of the square housing portion 6 are symmetrically provided with housing wings 7. The housing wings 7 are provided with a through housing square groove 11. The inner wall of the square housing portion 6 is provided with a housing bottom groove 12. The housing wings 7 are symmetrically provided with housing side through grooves 13. The two ends of the housing wings 7 are also symmetrically provided with housing notches 14. The housing notches 14 are provided with housing cylinders 15. The hemostatic bandage 5 is fixed on the housing cylinder 15, which can form a complete ring by connecting the main hemostatic housing 4 and the hemostatic bandage 5.

[0043] One end of the hemostatic bandage 5 is provided with a bandage fixing buckle 8. The hemostatic bandage 5 is connected to the housing cylinder 15 through the bandage fixing buckle 8. The other end of the hemostatic bandage 5 is provided with a bandage free end 9. The bandage free end 9 is wrapped around the housing cylinder 15. The bandage free end 9 is provided with Velcro 10. The main hemostatic housing 4 and the hemostatic bandage 5 form a complete ring, which can adapt to limbs of different diameters and can compress the bleeding arteries and veins through its own mobile mechanism to stop bleeding.

[0044] The local pressing mechanism 2 includes an elastic pressing piece 16 and a pressing control stud 17. The elastic pressing piece 16 is engaged in the groove 12 at the bottom of the housing, and the pressing control stud 17 is rotatably disposed in the elastic pressing piece 16.

[0045] The elastic pressing pad 16 is symmetrically provided with pressing pad fixing ends 18. The elastic pressing pad 16 is engaged in the through groove 13 on the side of the housing through the pressing pad fixing ends 18. The pressing pad fixing ends 18 are fixedly connected to the housing wing 7. The elastic pressing pad 16 is also provided with a pressing pad square boss 19. The pressing pad square boss 19 is provided with a pressing pad threaded hole 20. The two ends of the elastic pressing pad 16 are fixed to the main hemostatic housing 4. By the relative movement of the pressing pad square boss 19 after the main hemostatic housing 4 is fixed, the purpose of local pressing is achieved, and the purpose of blocking blood flow is achieved without tightening the whole circle.

[0046] The press control stud 17 is provided with a stud threaded portion 21, which is threadedly connected to the press plate threaded hole 20. The press control stud 17 is also provided with a stud polygonal portion 22. Through the threaded transmission between the press plate threaded hole 20 and the stud polygonal portion 22, the press control stud 17 can control the rise and fall of the press plate square boss 19 when it rotates, thereby squeezing the bleeding arteries and veins to stop the bleeding.

[0047] The positioning ring 37 is fixed in the square groove 11 of the housing. The pressing control stud 17 is rotated in the positioning ring 37. The positioning ring 37 makes the pressing control stud 17 only able to rotate on its own axis and unable to move axially.

[0048] The rotating fixing mechanism 3 includes a pressing control rod 23, a limiting component 24, and a control rod bracket 25. The pressing control rod 23 is engaged and slidably mounted on the pressing control stud 17, the limiting component 24 is located in the pressing control rod 23, and the control rod bracket 25 is located on the square part 6 of the housing.

[0049] The control lever 23 has a cylindrical part 26 and a cantilever part 27. The cylindrical part 26 has a polygonal countersunk groove 33. The polygonal part 22 of the stud is engaged and slidably disposed in the polygonal countersunk groove 33. The bottom of the polygonal countersunk groove 33 has a circular countersunk groove 34. The limiting component 24 is located in the circular countersunk groove 34. The cantilever part 27 is symmetrically disposed on both sides of the cylindrical part 26. The control lever 23 can slide along the polygonal part 22 of the stud. When the control lever 23 is raised, it can be disengaged from the limiting of the control lever bracket 25 and rotate. Since the engagement between the polygonal part 22 of the stud and the polygonal countersunk groove 33 of the control lever is still maintained, the control lever 23 can still drive the control stud 17 to rotate when it rotates.

[0050] The limiting assembly 24 includes an upper connecting piece 28, a lower connecting piece 29, and a limiting tension spring 30. The upper connecting piece 28 is fixed to the bottom of the circular countersunk groove 34 of the control lever, and the lower connecting piece 29 is fixed to the top of the polygonal portion 22 of the stud. The two ends of the limiting tension spring 30 are fixed to the upper connecting piece 28 and the lower connecting piece 29, respectively. The limiting assembly 24 can limit the maximum distance between the cylindrical portion 26 of the control lever and the polygonal portion 22 of the stud, and in a natural state, the cylindrical portion 26 of the control lever and the polygonal portion 22 of the stud tend to move closer to each other.

[0051] The control lever bracket 25 includes a main fixing bracket 31 and a secondary fixing bracket 32. The main fixing bracket 31 is symmetrically arranged on the square part 6 of the housing and is fixedly connected to the square part 6 of the housing. The main fixing bracket 31 is provided with a fixing bracket slot 35, and the cantilever rod part 27 is engaged in the fixing bracket slot 35. The secondary fixing bracket 32 ​​is symmetrically arranged on the square part 6 of the housing and is provided with a fixing bracket slot 36, and the cantilever rod part 27 is engaged in the fixing bracket slot 36.

[0052] In practical use, the user first needs to wrap the hemostatic bandage 5 around the limb that needs to be tightened, and tighten it by passing the free end 9 of the bandage through the cylinder 15 of the housing. When the tightening reaches the point where three fingers cannot be inserted into the gap between the hemostatic bandage 5 and the limb, the length of the free end 9 of the bandage is fixed by the Velcro 10. At this time, the square protrusion 19 of the pressing plate should correspond to the position of the target blood vessel.

[0053] After the winding is completed, the control lever 23 is lifted upwards, at which point the limit spring 30 is stretched. When the cantilever rod 27 is disengaged from the fixing bracket slot 35, the cylindrical part of the control rod 26 is rotated in the square groove 11 of the housing by rotating the cantilever rod 27.

[0054] When the cylindrical part 26 of the control lever rotates, the pressing control stud 17 also rotates. At this time, through the threaded transmission between the threaded part 21 of the stud and the threaded hole 20 of the pressing plate, the square boss 19 of the pressing plate can slide down along the square groove 11 of the housing to further press and stop bleeding at the target position.

[0055] Once the bleeding has been observed to have significantly decreased or disappeared, pressing the control lever 23 will cause the cantilever rod 27 to re-engage in the mounting bracket slot 35, thus maintaining the angle of the cylindrical part 26 of the control lever.

[0056] The secondary fixing bracket 32 ​​is a detachable connection and is not installed in the initial state. It is only rotated and installed when the cantilever rod 27 needs to be fixed at this location. The function of the secondary fixing bracket 32 ​​is the same as that of the main fixing bracket 31.
