Description

Technical Field

[0001] The present invention relates to hemostatic rescue equipment, and particularly to a neck compression hemostasis device. Background Art

[0002] In modern battlefields, traffic accidents, and disaster accidents, due to the physiological characteristics of the human neck and its exposure outside clothing, the neck is more vulnerable to injury. The neck has multiple important physiological structures, such as the bilateral carotid arteries, internal jugular veins, external jugular veins, and the trachea in the middle, all of which are important life support structures. Once the skin and soft tissues on both sides of the neck are damaged, it is very easy to cause neck vascular injury and secondary persistent massive bleeding. If the bleeding cannot be effectively controlled, it will lead to secondary hemorrhagic shock or even death. Therefore, it is particularly important to perform timely and effective wound hemostasis without affecting breathing. The current common treatment method is to apply a gauze dressing or hemostatic material to press on the bleeding wound surface, and the wounded can press the wound by themselves for self-help. However, if the upper limb of the wounded is also injured during the incident, or there is bleeding in other parts of the body that needs to be treated, it is difficult for the wounded to press by themselves. Moreover, the wounded pressing the wound by themselves for a long time restricts the upper limb and causes great inconvenience to subsequent activities such as avoiding harm and transferring. Due to the special physiological structure of the neck, in order to ensure the patency of the respiratory tract, the pressure that the trachea can withstand is very limited, so it is not applicable to use a bandage to wrap around the neck to compress the wound. Therefore, developing a neck hemostatic device with a pressing function is an important issue in combat injury rescue. In some existing technical solutions, a neck brace structure is adopted, and a pressing device such as an airbag is arranged inside the neck brace. However, such devices must apply pressure to both sides of the neck to obtain pressure balance. There are main arteries and veins on both sides of the neck, which are responsible for supplying and returning the blood perfusion required by the brain. Compression of the blood vessels on one side of the neck can be compensated by the other side to ensure blood supply to the brain. However, simultaneously compressing both sides of the neck will affect blood circulation in the brain and have an obvious adverse effect on cerebral blood supply. Especially, long-term bilateral neck compression will cause serious cerebral blood supply insufficiency or poor blood return, which is harmful to the human body. Another technical solution is to wear special clothing, and a pressing device arranged on the clothing is used to apply pressure to the neck. However, the clothing-type device lacks sufficient rigidity, and it is difficult for such a device to obtain a good fixing effect and maintain a good neck compression function, and it is rarely used in practice. Summary of the Invention

[0003] The purpose of the present invention is to provide a neck compression hemostasis device to achieve pressing hemostasis for neck trauma and ensure the breathing function and mobility of the wounded.

[0004] To achieve the above purpose, the technical solution of the present invention is: a neck compression hemostasis device, including a scapula worn on one shoulder of the human body, and a pressing body for pressing the side neck or the back neck is arranged on the scapula.

[0005] Furthermore, in order to match the scapula with the human body, the scapula is a scapula covering the upper part of the torso. The scapula is an armor corresponding to the shoulders, side ribs and collarbones. The side of the scapula facing the human body is an open end, and the scapula is provided with scapula holes for the arms to pass through.

[0006] In order to firmly wear the scapula on the human body, the lower part of the scapula corresponds to the upper abdomen, and a tightening band is provided at the lower part of the scapula. The tightening band surrounds the upper abdomen to tighten the scapula on the human body.

[0007] Furthermore, in order to enable the scapula to provide good support for the compression body and maintain the mechanical stability of the scapula, the scapula includes a lower edge, a collarbone edge, a neck side edge and an armpit edge, and soft pads are provided at the lower edge, collarbone edge, neck side edge and armpit edge.

[0008] Furthermore, in order to avoid pressing on the front side of the neck, the scapula extends to the other side of the human body on the front side.

[0009] Furthermore, in order to effectively fix the compression body, the scapula is provided with a front support hole and a side support hole. The front support hole is arranged at the position of the scapula facing the front side of the human body, and the side support hole is arranged at the position of the scapula corresponding to the human shoulder. The compression body is installed on the scapula through the front support hole or the side support hole.

[0010] Furthermore, the structure of a compression body is that the compression body is an elastic compression sheet. The elastic compression sheet is provided with a compression sheet mounting rod. The elastic compression sheet is connected to the mounting rod through a scroll spring section at the root. The compression sheet mounting rod is provided with a mounting joint, and the elastic compression sheet is installed in the front support hole or the side support hole through the mounting joint.

[0011] Furthermore, the structure of a compression body is that the compression body is a compression band. Both ends of the compression band are respectively provided with band rods. The band rods at both ends of the compression band are respectively connected to the front support hole and the side support hole. The band rods are provided with mounting joints, and the compression band is installed in the front support hole or the side support hole through the mounting joints.

[0012] Furthermore, in order to facilitate the feature and installation of the compression body, the front support hole and the side support hole are square holes, and the mounting joint is a square shaft corresponding to the front support hole and the side support hole.

[0013] Furthermore, the scapula includes a left scapula and a right scapula, and the left scapula and the right scapula have the same symmetrical structure.

[0014] The beneficial effects of the present invention are as follows: A scapula with good rigidity is used as a support body. The structure of the scapula enables it to be firmly fixed on the shoulder on one side of the human body and avoids affecting breathing and basic activities. The connection structure between the compression device and the scapula enables the elastic compression piece and the compression belt to perform neck compression on the neck, avoiding the harm caused by compressing both sides of the neck simultaneously. The installation joint that uses a square hole to connect the elastic compression piece and the compression belt can facilitate connection and adjustment of the compression force on the neck.

[0026] Such as Figures 1 to 10 , A neck compression hemostasis device includes a scapula 10 worn on the shoulder on one side of the human body, and a compression body for compressing the side neck or the back neck is provided on the scapula.

[0027] The scapular is a scapular covering the upper part of the torso. The scapular is armor corresponding to the shoulders, side ribs, and collarbone. The side 11 of the scapular facing the human body is an open end, and the scapular is provided with a scapular hole 12 for the arm to pass through.

[0028] The lower part of the scapular corresponds to the upper abdomen, and a tightening band 13 is provided at the lower part of the scapular. The tightening band surrounds the upper abdomen to fasten the scapular to the human body.

[0029] As Figure 4 shown, the scapular includes a lower edge 1A, a collarbone edge 1B, a neck side edge 1C, and an armpit edge 1D. Soft pads are provided on the lower edge, collarbone edge, neck side edge, and armpit edge. As Figure 2 (18).

[0030] The scapular extends to the other side of the human body on the front side. As Figure 3 (14).

[0031] The scapular is provided with a front support hole 15 and a side support hole 16. The front support hole is arranged at the position of the scapular facing the front side of the human body, and the side support hole is arranged at the position of the scapular corresponding to the human shoulder. The pressing body is installed on the scapular through the front support hole or the side support hole.

[0032] The structure of a pressing body is that the pressing body is an elastic pressing piece 20. The elastic pressing piece is provided with a pressing piece mounting rod 21. The elastic pressing piece is connected to the mounting rod through a scroll spring section 22 at the heel. The pressing piece mounting rod is provided with a mounting joint 40. The elastic pressing piece is installed in the front support hole or the side support hole through the mounting joint.

[0033] Another structure of the pressing body is that the pressing body is a pressing band 30. Both ends of the pressing band are respectively provided with a band rod 31. The band rods at both ends of the pressing band are respectively connected to the front support hole and the side support hole. The band rod is provided with a mounting joint 40. The pressing band is installed in the front support hole or the side support hole through the mounting joint.

[0034] The front support hole and the side support hole are square holes, and the mounting joint is a square shaft corresponding to the front support hole and the side support hole.

[0035] The scapular includes a left scapular and a right scapular, and the left scapular and the right scapular have the same symmetrical structure.

[0036] Example 1:

[0037] As Figures 1 to 4, a scapular 10, worn on the shoulder on one side of the human body. The scapular is a scapular covering the upper part of the torso. The scapular is a kind of armor structure, that is, the scapular is made of a material with sufficient rigidity, such as plastic, carbon fiber and other materials. The side 11 of the scapular facing the human body is an open end. The scapular is provided with a scapular hole 12 for the arm to pass through, and the scapular can be conveniently worn on the shoulder and the upper part of the torso on one side of the body.

[0038] The scapular includes a left scapular and a right scapular. The left scapular is worn on the left side of the human body, and the right scapular is worn on the right side of the human body. The left scapular and the right scapular are symmetric and identical structures. In the drawings of this embodiment, the left scapular is taken as an example.

[0039] The scapular covers the shoulders, side ribs and collarbones of the human body. The lower part of the scapular corresponds to the upper abdomen. A tightening belt 13 is provided at the lower part of the scapular. The tightening belt is connected by a nylon 17 hook-and-loop fastener. The tightening belt surrounds the upper abdomen to tighten the scapular on the human body. The parts of the scapular relative to the front chest and the back chest are of a hollow structure to avoid affecting the normal breathing function of the lungs.

[0040] The scapular extends to the other side of the human body on the front side, such as Figure 3 (14), to improve the compression effect on the lateral neck and avoid affecting the front neck.

[0041] Such as Figure 4 As shown, the function of the scapular is to support the compression body and exert pressure on the neck. Therefore, when the scapular supports the compression body, it mainly bears three kinds of acting forces, the lateral acting force F1, the back acting force F2, the lateral torque R1, and the back torque R2.

[0042] The main parts where the scapular contacts and fixes with the human body include the lower edge 1A, the collarbone edge 1B, the lateral neck edge 1C and the armpit edge 1D. After the scapular is worn on the human body and tightened by the tightening belt 13, in the middle and nearby areas of the lower edge 1A, the scapular obtains a lateral supporting force G1 in the direction of the inner side of the body. Due to the supporting effect of the upper abdomen of the human body, a supporting force G2 in the direction of the outer front can be obtained at the front end and nearby areas of the lower edge, and a supporting force G3 in the direction of the outer rear can be obtained at the rear end and nearby areas of the lower edge. At the same time, due to the tightening belt surrounding the upper abdomen (or the lower rib part), an appropriate vertical supporting force G4 in the downward direction can be obtained. In the collarbone edge 1B and the nearby areas, the scapular obtains a supporting force G5 in the direction of the outer front side of the body. In the lateral neck edge 1 and the nearby areas C, the scapular obtains a supporting force G6 in the direction of the outer side of the body. In the armpit edge 1D, the scapular obtains a supporting force G7 in the direction of the outer side of the body and a vertical supporting force G8 in the downward direction.

[0043] The lateral support force G6 along the lateral side of the scapula at the neck side and the lateral support force G7 along the armpit side can balance the lateral acting force F1 borne by the scapula. The anterior lateral support force G5 along the collarbone of the scapula can balance the backward acting force F2 borne by the scapula. The lateral support force G1 at the lower edge 1A of the scapula can balance the lateral torque R1 borne by the scapula. The rear support force G3 at the rear end of the lower edge of the scapula can balance the backward torque R2 borne by the scapula. Therefore, the scapula can stably support the compression body and exert pressure on the neck.

[0044] To obtain a stable support effect and improve the wearing comfort, soft pads are provided at the lower edge 1A, the collarbone edge 1B, the neck side edge 1C and the armpit edge 1D, as Figure 2 shown in (18). The soft pads can be made of sponge or compressible materials.

[0045] The scapula is provided with a front support hole 15 and a side support hole 16. The front support hole is arranged at the position of the scapula facing the front side of the human body, and the side support hole is arranged at the position of the scapula corresponding to the shoulder of the human body. For the convenience of use, the scapula can be provided with multiple front support holes and side support holes. In this embodiment, two front support holes and two side support holes are provided. The front support hole and the side support hole are square holes, and the square hole can be a four-sided hole, a six-sided hole or a square hole with more faceted surfaces. In this embodiment, a four-sided hole is adopted.

[0046] Embodiment Two:

[0047] As Figures 5 to 8 shown, a neck compression hemostasis device includes the scapula 10 described in Embodiment One, and a compression body for compressing the lateral neck or the posterior neck is provided on the scapula.

[0048] In this embodiment, the compression body is an elastic compression sheet 20, and the elastic compression sheet is made of a material with good elasticity, such as elastic plastic or metal material. The elastic compression sheet is provided with a sheet mounting rod 21, and the elastic compression sheet is connected to the mounting rod 21 through a coiled spring section 22 at the root.

[0049] The elastic compression sheet is mounted on the scapula through the front support hole 15 or the side support hole 16 of the scapula. The front support hole and the side support hole of the scapula are square holes. An installation joint 40 is provided at the root of the sheet mounting rod. The elastic compression sheet is mounted in the front support hole or the side support hole through the installation joint. The installation joint is a square shaft corresponding to the front support hole and the side support hole of the scapula. Insert the installation joint 40 into the front support hole or the side support hole, and the front support hole and the side support hole can prevent the sheet mounting rod from rotating, so that the elastic compression sheet maintains the compression force on the neck. Rotating the sheet mounting rod, through the elastic deformation of the coiled spring section 22 at the root, the compression strength of the elastic compression sheet 20 on the neck can be adjusted.

[0050] Taking the left scapula as an example in this embodiment, as Figure 6As shown in the figure, when there is a trauma on the right side of the wounded's neck and continuous bleeding occurs, first use the hemostatic material 50 to cover the wound surface, and then lay a pressing block 51 on the hemostatic material. The pressing block 51 is an elastic cushion block, such as a sponge block. The pressing block can apply the pressing force of the elastic pressing piece to the neck wound. Then, as Figure 7 shown, insert the installation joint 40 into the front support hole. The shoulder armor of this embodiment is provided with two front support holes, and a suitable front support hole can be selected according to the location of the trauma. If it is necessary to adjust the pressing force, rotate the pressing piece installation rod to make the elastic deformation of the root scroll spring section 22, and then the pressing force of the elastic pressing piece 20 on the neck can be changed. The cooperation of the square hole and the square shaft for the front support hole and the installation joint can prevent the pressing piece installation rod from rotating, so that the elastic pressing piece can maintain the pressing force on the neck and perform compression hemostasis.

[0051] As Figure 8 shown, an elastic pressing piece installed in the side support hole can also be used to perform compression hemostasis on the trauma site at the back of the neck.

[0052] The elastic pressing piece can be used to perform compression hemostasis on the side or back of the neck respectively, or two elastic pressing pieces can be used to perform compression hemostasis on the side and back of the neck at the same time.

[0053] Embodiment Three:

[0054] As Figures 9 to 10 , a neck compression hemostasis device includes the shoulder armor 10 described in Embodiment One, and the shoulder armor is provided with a pressing body for pressing the side or back of the neck.

[0055] In this embodiment, the pressing body is a pressing band 30. The pressing band is an elastic bandage. Both ends of the pressing band are respectively provided with a band rod 31. The pressing band is installed on the shoulder armor through the front support hole 15 and the side support hole 16 of the shoulder armor. The front support hole and the side support hole of the shoulder armor are square holes. The root of the band rod is provided with an installation joint 40, and the installation joint is a square shaft corresponding to the front support hole and the side support hole of the shoulder armor. The band rods at both ends of the pressing band are respectively connected to the front support hole and the side support hole of the shoulder armor, and the installation joints of the band rods are inserted into the front support hole or the side support hole. The front support hole and the side support hole can prevent the band rod from rotating, so that the pressing band can maintain the pressing force on the neck. Rotating the band rod and winding the pressing band can adjust the pressing force of the pressing band 30 on the neck.

[0056] Taking the left shoulder armor as an example in this embodiment, when there is a trauma on the right side of the wounded's neck and continuous bleeding occurs, similar to Embodiment Two, first use the hemostatic material to cover the wound surface, and then lay a pressing block on the hemostatic material. Then, as Figure 10As shown, insert the mounting joints 40 at both ends of the compression band into the front support holes and side support holes of the shoulder armor respectively. The shoulder armor in this embodiment is provided with two front support holes and two side support holes, and a suitable front support hole and a side support hole can be selected according to the required neck compression range. If it is necessary to adjust the compression force, rotate the belt rod and wind the compression band, then the compression force of the compression band 30 on the neck can be changed. The front support holes and the mounting joints with square holes and square shafts can prevent the belt rod from rotating, keep the compression band pressing on the neck, and perform compression hemostasis.

[0057] In this embodiment, the compression band is used as the compression body, which can perform compression hemostasis on large-area wounds on the lateral and posterior parts of the neck.
