Abstract
Description
Technical Field
[0001] This utility model relates to the field of tourniquet technology, specifically to a portable femoral artery tourniquet. Background Technology
[0002] The proper use of hemostatic devices and consumables is the most effective way to preserve vital forces and maintain effective circulating blood volume in emergency arterial bleeding control. Conventional hemostatic methods (such as hemostatic dressing packing, tourniquet hemostasis, and vascular occlusion devices) are not suitable for hemostasis at junctional sites, cannot achieve hemostasis in one go, and are complex to operate. In complex conditions such as in the field, slippage and inaccurate positioning are prone to occur. To effectively control femoral artery bleeding and simplify operation, a rapid hemostatic device for the femoral artery was designed and manufactured. Considering factors such as frequency of use, the hemostatic device is made for external use and can be reused. This reduces the impact of factors such as medical resource shortages and material scarcity. At the same time, the development of this device is essential to reduce the incidence of hypovolemic shock and even death caused by femoral artery bleeding.
[0003] According to a public disclosure of a portable femoral artery hemostat (publication number: CN 209678616 U), it includes a housing, a first groove at the bottom of the housing, and second grooves on both sides of the first groove. The first groove contains a strip plate and an elastic airbag, with the elastic airbag located at the top of the strip plate. The bottom of the strip plate is bonded to the top of a tourniquet through an adhesive layer. Movable blocks are fixedly installed at the top of both sides of the strip plate. The bottom of each of the two movable blocks is fixedly connected to the groove wall at the bottom of the corresponding second groove through a telescopic spring. A pressing airbag is provided on one side of the housing.
[0004] In the aforementioned application, the cooperation between components such as the first groove and the second groove makes it difficult to solve the problem of not being able to perform self-rescue while performing mutual rescue, which leads to a prolongation of treatment time, increases the operation time in actual application, and delays treatment, and needs to be improved. Utility Model Content
[0005] This invention proposes a portable femoral artery tourniquet, which solves the problem of long operation time and delayed treatment in practical applications mentioned in related technologies.
[0006] The technical solution of this utility model is as follows: a portable femoral artery tourniquet, including a shell, a multi-functional tactical waist belt fixedly connected to the top of the shell, a rotary pressure hemostasis device provided on the side of the shell, the rotary pressure hemostasis device including a spiral bar, one end of the spiral bar being rotatably connected to the outer wall of the shell, a blunt strip-shaped pressure head being threadedly connected to the circumferential surface of the spiral bar, and a knob being fixedly connected to the end of the spiral bar away from the shell.
[0007] Furthermore, two of the spin-type pressure hemostasis devices are provided and are symmetrical to each other along the vertical central axis of the housing. The housing is located on the displacement trajectory of the passivated strip pressure head. This design facilitates the compression of the groin area when the passivated strip pressure head moves, thereby achieving hemostasis.
[0008] Furthermore, a D-ring is fixedly connected to the side of the housing, and a quick-release buckle is provided on the circumferential surface of the D-ring. An adjustable Velcro is fixedly connected to the inner wall of the multi-functional tactical waist belt. The design of the D-ring and quick-release buckle makes it convenient to carry and store the multi-functional tactical waist belt.
[0009] Furthermore, the outer wall of the multi-functional tactical waist belt is provided with a Velcro loop surface and a Velcro hook surface. The Velcro loop surface is located on the displacement trajectory of the Velcro hook surface. The Velcro hook surface is attached to the Velcro loop surface by the hooks on the Velcro hook surface, thus fixing the multi-functional tactical waist belt to the user.
[0010] Furthermore, a fixing strap is provided on the outer wall of the multi-functional tactical waist belt, and the D-ring and quick-release buckle are located on the top of the housing. The D-ring and quick-release buckle are made of metal, and the multi-functional tactical waist belt is further fixed to the user by the upper squeeze buckle of the fixing strap.
[0011] Furthermore, the multi-functional tactical waist belt is internally equipped with a comfort protection component, which includes a surface layer disposed on the inner wall of the multi-functional tactical waist belt, a support layer disposed below the surface layer, and a protective layer disposed below the support layer. Both the support layer and the protective layer are disposed on the inner wall of the multi-functional tactical waist belt. Through these different layer combinations, the portable femoral artery tourniquet can provide effective blood flow control in emergency situations while ensuring the user's comfort and safety.
[0012] Furthermore, the surface layer is located between the multifunctional tactical waist band and the support layer. The interior of the surface layer includes synthetic materials such as nylon and polyester, and the surface layer has a certain degree of water resistance and corrosion resistance. Its main function is to protect the internal structure of the tourniquet from damage caused by the external environment.
[0013] Furthermore, the support layer is located between the surface layer and the protective layer. The interior of the support layer includes plastic or metal strips. This support layer mainly provides structural support for the tourniquet, ensuring that the tourniquet will not deform or loosen in an emergency.
[0014] Furthermore, the protective layer is located between the support layer and the multi-functional tactical waist belt. The interior of the protective layer includes foam, soft fabric, or non-woven fabric. This protective layer is located at the innermost layer of the tourniquet and is usually made of soft, comfortable material to reduce friction and pressure of the band on the skin.
[0015] Furthermore, the spiral winch, the blunt strip pressure head, and the knob are located at the bottom of the housing, while the adjustable Velcro is located on the side of the D-ring and quick-release buckle. This design prevents them from being used directly together and effectively keeps them separate.
[0016] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, the spiral-shaped wrench, the blunted strip-shaped pressure head, the knob and other components inside the rotary pressure hemostasis device cooperate with each other to achieve the purpose of emergency hemostasis of massive arterial bleeding in the lower limbs by compression. The device compresses and blocks arterial blood flow above the femoral artery in the groin, thereby reducing distal bleeding and ensuring emergency hemostasis for the injured and sick to reduce the amount of bleeding. The device can realize mutual rescue and self-rescue at the same time. The knob is set on the side to realize the function of quick operation for self-rescue.
[0017] 2. In this utility model, through the cooperation between the surface layer, support layer, and protective layer of the comfort protection component, the surface layer provides waterproof and corrosion-resistant properties, protecting the internal structure of the tourniquet from damage by the external environment. The support layer provides structural support for the tourniquet, ensuring that the tourniquet will not deform or loosen in an emergency. This is intended to ensure that the tourniquet remains stable and effectively wraps the injured area when pressure is applied. The protective layer reduces friction and pressure between the tourniquet and the skin, so as to avoid damage or pain to the skin caused by prolonged pressure. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] Example 1 like Figures 1-5 As shown, this embodiment proposes a portable femoral artery tourniquet, including a housing 1. A multi-functional tactical waist belt 2 is fixedly connected to the top of the housing 1. A rotary pressure hemostasis device 3 is provided on the side of the housing 1. The rotary pressure hemostasis device 3 includes a spiral bar 31. One end of the spiral bar 31 is rotatably connected to the outer wall of the housing 1. A blunt strip-shaped pressure head 32 is threadedly connected to the circumferential surface of the spiral bar 31. A knob 33 is fixedly connected to the end of the spiral bar 31 away from the housing 1.
[0023] Two spin-type pressure hemostasis devices 3 are provided and are symmetrical to each other along the vertical central axis of the housing 1. The housing 1 is located on the displacement trajectory of the passivated strip pressure head 32. This design makes it convenient to squeeze the groin area when the passivated strip pressure head 32 moves, thereby achieving hemostasis.
[0024] A D-ring 34 is fixedly connected to the side of the shell 1. A quick-release buckle 35 is provided on the circumference of the D-ring 34. An adjustable Velcro 36 is fixedly connected to the inner wall of the multi-functional tactical waist belt 2.

[0025] The outer wall of the multi-functional tactical waist belt 2 is provided with a Velcro loop surface 37 and a Velcro hook surface 38. The Velcro loop surface 37 is located on the displacement trajectory of the Velcro hook surface 38. The Velcro hook surface 38 is attached to the Velcro loop surface 37 by the hooks on the Velcro hook surface 38, thus fixing the multi-functional tactical waist belt 2 to the user.
[0026] The multi-functional tactical waist belt 2 has a fixing strap 39 on its outer wall. The D-ring 34 and quick-release buckle 35 are located on the top of the housing 1. The D-ring 34 and quick-release buckle 35 are made of metal. The multi-functional tactical waist belt 2 is further fixed to the user by the upper compression buckle of the fixing strap 39.
[0027] In this embodiment, the multi-functional tactical waist belt 2 is worn on the patient using adjustable Velcro 36, Velcro loop 37, and Velcro hook 38. It is fixed to the pelvic position using a three-point wearing method. Rotating the knob 33 drives the spiral wrench 31 to rotate downwards. The rotation of the spiral wrench 31 drives the blunt strip pressure head 32 to rotate downwards. The blunt strip pressure head 32 rotates downwards to the groin area, applying pressure to stop bleeding. This method of pressure hemostasis achieves the purpose of emergency hemostasis for massive arterial bleeding in the lower limb. By compressing and blocking arterial blood flow above the femoral artery in the groin, the device reduces distal bleeding and ensures emergency hemostasis for the injured or sick, reducing the amount of bleeding. This device can achieve both mutual rescue and self-rescue. The knob 33 on the side allows for quick operation for self-rescue.
[0028] Example 2 like Figures 3-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes another embodiment. The multi-functional tactical waist belt 2 is provided with a comfort protection component 4 inside. The comfort protection component 4 includes a surface layer 41, which is disposed on the inner wall of the multi-functional tactical waist belt 2. A support layer 42 is disposed below the surface layer 41, and a protective layer 43 is disposed below the support layer 42. Both the support layer 42 and the protective layer 43 are disposed on the inner wall of the multi-functional tactical waist belt 2. Through these different layer combinations, the portable femoral artery tourniquet can provide effective blood flow control in emergency situations while ensuring the comfort and safety of the user.
[0029] The surface layer 41 is located between the multi-functional tactical waist belt 2 and the support layer 42. The interior of the surface layer 41 includes synthetic materials such as nylon and polyester, and the surface layer 41 has a certain degree of water resistance and corrosion resistance.

[0030] The support layer 42 is located between the surface layer 41 and the protective layer 43. The interior of the support layer 42 includes plastic or metal strips. This support layer 42 mainly provides structural support for the tourniquet, ensuring that the tourniquet will not deform or loosen in an emergency.
[0031] The protective layer 43 is located between the support layer 42 and the multi-functional tactical waist belt 2. The interior of the protective layer 43 includes foam, soft fabric or non-woven fabric. This protective layer 43 is located at the innermost layer of the tourniquet and is usually made of soft, comfortable material to reduce friction and pressure on the skin.
[0032] The spiral wrench 31, the blunt strip pressure head 32, and the knob 33 are located below the housing 1. The adjustable Velcro 36 is located on the side of the D-ring 34 and the quick-release buckle 35. This design prevents them from being used directly together and can effectively keep them separate.
[0033] In this embodiment, the multi-functional tactical waist belt 2 is protected by the surface layer 41, support layer 42, and protective layer 43 inside the comfort protection component 4.
