Description

Technical Field

[0001] This invention pertains to a type of tourniquet, specifically a novel tourniquet for battlefield border areas. Background Technology

[0002] Massive hemorrhage is a leading preventable cause of death on the modern battlefield, and hemorrhage control is fundamental to tactical combat wound care (TCCC) and damage control resuscitation (DCR). The use of tourniquets at the point of injury has significantly improved the survival rate of wounded soldiers with limb trauma and bleeding, but massive hemorrhage at junctional sites such as the groin remains difficult to control. Junctional hemorrhage refers to bleeding occurring between adjacent anatomical regions of the body, such as the junction of a limb and the trunk (e.g., the armpit, groin). These areas contain important blood vessels, nerves, and multiple organ systems, making compression hemostasis difficult and leading to rapid blood loss. Junctional hemorrhage is a significant cause of combat casualty death.

[0003] The main technical approaches used in current mainstream products can be categorized as follows: ① Using steel supports and screws for pressure, such as the CRoC (Combat Ready Clamp), suitable for the armpit and groin, but complex to assemble and time-consuming to operate. ② Using a nylon belt and T-shaped handle design, such as the JETT (Junctional Emergency Treatment Tool), easy to operate, but poor durability and uneven pressure distribution. ③ Combining an inflatable balloon and pressure pad, such as the SJT (SAM Junctional Tourniquet), which can treat bleeding and pelvic fractures simultaneously, but is bulky and inconvenient to carry. ④ Using air to compress the abdominal aorta or iliac artery, such as the AAJT (Abdominal Aortic Junctional Tourniquet), which has a significant hemostatic effect, but is painful, and prolonged use may lead to ischemic injury. Summary of the Invention

[0004] The purpose of this invention is to provide a novel tourniquet for battlefield boundary areas, which solves the problems of existing tourniquets such as poor hemostasis effect in boundary areas (such as the groin), complicated operation, uneven pressure distribution, and poor comfort.

[0005] The above-mentioned technical objective of the present invention is mainly achieved through the following technical solution: a novel battlefield boundary zone tourniquet, comprising a non-elastic wrapping piece that can be circumferentially wrapped around the groin and buttocks of the wounded, and two fixing pieces located at the lower edge of the wrapping piece and circumferentially wrapped around the thighs of the wounded. The wrapping piece is provided with a first disconnection area that can be quickly connected and disconnected. The two fixing pieces are symmetrically arranged on both sides of the disconnection end. The fixing pieces are provided with a second disconnection area that can be quickly connected and disconnected. When the wrapping piece is closed, a compression area is provided on its inner side corresponding to the location of the groin on both sides of the wounded. The compression area is provided with a compression member that can expand and compress the groin of the wounded.

[0006] As a further preferred technical solution of the present invention, the compression member is an inflatable airbag, and the side wall of the compression member is provided with an air tube that can extend outside the compression area, and the end of the air tube is provided with an inflation member and an air pressure gauge.

[0007] As a further preferred technical solution of the present invention, the compression area is a chamber formed by an elastic sheet and capable of accommodating the compression member. The upper side of the compression area is open, and the air tube and the inflation member of the compression member extend to the outside of the surrounding sheet.

[0008] As a further preferred technical solution of the present invention, a plurality of tightening structures are provided longitudinally at the first disconnection area. The tightening structure includes a first connecting strip and a second connecting strip that are respectively connected to both ends of the surrounding piece. The outer side of the first connecting strip is provided with Velcro, and the end of the second connecting strip is provided with a tightening buckle. One end of the first connecting strip is wrapped around the tightening buckle.

[0009] As a further preferred technical solution of the present invention, a plurality of tightening structures are provided longitudinally at the second disconnection area, and the tightening structure at the second disconnection area is consistent with the tightening structure at the first disconnection area.

[0010] As a further preferred technical solution of the present invention, the opening of the compression area is provided with a third connecting strip that connects to the inner side of the surrounding piece. The third connecting strip can be connected to the outer wall of the compression area through the opening of the compression area, and the third connecting strip and the outer wall of the compression area are connected by a hook and loop fastener.

[0011] Therefore, this invention has the characteristics of solving the problem of hemostasis in the junction area, simplifying operation, lowering the training threshold, improving portability and comfort, reducing costs, increasing popularization rate, and being intelligent and multifunctional.

Detailed Implementation

[0013] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0014] like Figure 1-2As shown, a novel battlefield boundary zone tourniquet includes a non-elastic wrapping piece 1 that can circumferentially wrap around the groin and buttocks of a wounded person, and two fixing pieces 2 located at the lower edge of the wrapping piece 1 and circumferentially wrap around the thighs of the wounded person. The wrapping piece 1 and the fixing pieces 2 are integrally formed and supported by cutting and sewing. In this embodiment, both the wrapping piece 1 and the fixing pieces 2 are made of high-quality fabric and are non-elastic, so that when the wrapping piece 1 is wrapped around the buttocks and groin, it can remain fixed and prevent displacement due to its own elasticity. At the same time, it maintains the compression effect on the compression member 3, so that when the compression member 3 expands, its outer side is pressed and limited by the wrapping piece 1, thereby... This design allows the compression element 3 to collide inwards and compress the patient's groin area, preventing the compression element 3 from being unable to effectively compress the groin area due to the elasticity of the surrounding piece 1. It also prevents the surrounding piece 1 from shifting along with the compression element 3, thus ensuring proper compression. The two fixing pieces 2 can wrap around the patient's thighs, positioning the surrounding piece 1 and preventing displacement of the surrounding piece 1 and compression element 3 during hemostasis, which would affect stable hemostasis. This design is also more portable and comfortable. The surrounding piece 1 has a first disconnection area 11 for quick connection and disconnection, with the two fixing pieces 2 symmetrically positioned on either side of the disconnection end 11. The fixing pieces 2 also have features that allow for quick connection and disconnection. The quick-connecting and disconnecting second disconnection zone 21, along with the first disconnection zone 11 and the second disconnection zone 21, allows rescuers to directly flatten the surrounding piece 1 and the fixing piece 2 when the injured person is lying down, and insert them into the area where the injured person is in contact with the ground for wrapping and fixation. This reduces movement of the injured person's limbs and avoids secondary injury, making wrapping more convenient. When the surrounding piece 1 is closed, its inner side is provided with compression zones 12 corresponding to the locations of the injured person's groins on both sides. The compression zones 12 contain expansionable compression elements 3 that can compress the injured person's groins. When the surrounding piece 1 is closed and wrapped, two compression elements 3 are provided on the inner side corresponding to the locations of the injured person's groins on both sides. Each compression zone 12 has a compression element 3 that can be placed in any one of the compression zones 12, or in both compression zones 12 as needed. This allows for targeted compression and hemostasis of the groin area, resulting in better hemostasis and more even pressure distribution, making the patient more comfortable. It also simplifies the hemostasis process and lowers the training threshold. The compression element 3 and the compression zone 12 are set up independently, and the compression element 3 can be placed in or removed from the compression zone 12 at any time. This reduces the storage volume of the surrounding piece 1 and the fixing piece 2, and provides safer and more protective storage for the compression element 3, making it more portable and reducing costs.

[0015] like Figure 1-3As shown, the compression member 3 is an inflatable airbag. In this embodiment, the compression member 3 is an impact-resistant inflatable airbag, but it can also be a balloon that can be filled with liquid or fluid. After the compression member 3 expands with the filling medium, it is compressed and limited by the surrounding sheet 1. The compression member 3 can expand and squeeze towards the groin of the injured person to achieve compression hemostasis. The side wall of the compression member 3 is provided with a trachea 31 that can extend outside the compression area 12. The end of the trachea 31 is provided with an inflation member 32 and a pressure gauge 33. The compression member 3 is connected to the trachea 31, and the end of the trachea 31 is connected to... The inflator 32 and pressure gauge 33 are connected. The inflator 32 can be manually operated and connected to the pressure gauge 33 to display the pressure value. This allows for more precise and controllable pressure application from the compression device 3 to the injured person's groin, preventing excessive or insufficient pressure from affecting hemostasis. It also increases portability and reduces costs. Alternatively, the inflator 32 can be equipped with an electric air pump, allowing for more precise control of the pressure applied by the compression device 3 to the injured person's groin. This also results in faster and more effortless expansion of the compression device 3, thereby improving pressure application to the injured person's groin. To improve the efficiency of compression hemostasis, a pressure sensor 30 is provided on the side of the compression member 3 that contacts the groin of the injured person. When the compression member 3 expands and contacts and compresses the groin of the injured person, the pressure sensor 30 is connected to the external controller. The pressure sensor 30 transmits the sensed pressure value to the controller, so that the rescue personnel can more accurately and intuitively observe the pressure of the compression member 3 on the groin of the injured person, and control the expansion pressure of the compression member 3 to be within the most suitable compression hemostasis range, so as to avoid the patient's discomfort due to excessive pressure or the hemostasis effect due to insufficient pressure. The compression area 12 is a chamber formed by an elastic sheet and can accommodate the compression member 3. The compression area 12 is an area formed by an elastic material (such as rubber) connected to and enclosed by the inner side of the surrounding sheet 1, and this area is a chamber that can accommodate the compression member 3, so as to facilitate the positioning of the compression member 3, so that the compression member 3 can be quickly aligned with the position of the injured person that needs to be compressed and held in that position for compression, improving the accuracy and efficiency of compression positioning, and preventing the compression member 3 from shifting during compression hemostasis.

[0016] like Figure 3-4As shown, the air tube 31 is provided with a fixed cylinder 34 at one end, and a connecting cylinder 35 is provided with the other end of the fixed cylinder 34. The two ends of the connecting cylinder 35 are respectively threaded to the pipes of the fixed cylinder 34 and the inflator 32, so as to facilitate quick assembly and disassembly of the air tube 31 and the inflator 32, making it convenient to store and carry. It can also be inflated by using a manual airbag or an electric air pump according to different actual needs. The fixed cylinder 34 contains an axially movable column 341, and the end of the movable column 341 facing the air tube 31 is provided with a seal. Block 342, the inner side of the fixed cylinder 34 is provided with an annular sealing seat 343 that can seal with the sealing block 342. On the inner wall of the fixed cylinder 34, corresponding to the upper part of the annular sealing seat 343, there is a fixed frame 344 that slides with the side wall of the movable column 341. The other end of the movable column 34 is provided with a limiting block 345 that can abut against the end face of the fixed frame 344. A telescopic spring 346 is provided between the fixed frame 344 and the sealing block 342. Under normal conditions, the sealing block 342 is in contact with the annular sealing seat 343 by the action of the telescopic spring 346. The sealed fit prevents the air tube from entering, or allows for direct disassembly of the connecting cylinder 35 and the inflator 32 after inflation. This provides storage and protection for the inflator 32, preventing damage and maintaining the expansion and compression of the compression member 3, making it more convenient to use. The connecting cylinder 35 has a push rod 351 in the middle that can push the movable column 341. During inflation, the connecting cylinder 35 is threaded to the end of the fixed cylinder 34. After connection, the end of the movable column 341 can be pushed by the push rod 351. The limiting block 345 causes the sealing block 342 at the other end of the movable column 341 to separate from the annular sealing seat 343 and maintain the separation state, so that gas can flow into the pressure member 3 to inflate and expand the pressure member 3. After the inflation and expansion are in place, the inflation member 32 is closed, and the connecting cylinder 35 is turned to separate the connecting cylinder 35 from the fixed cylinder 34. The sealing block 342 can then cooperate with the annular sealing seat 343 to seal the fixed cylinder 34, thereby achieving the closure of the air pipe 31 and maintaining the expansion state of the pressure member 3.

[0017] like Figure 1-2As shown, the upper side of the compression zone 12 is open. The air tube 31 and the inflation component 32 of the compression member 3 both extend to the outside of the surrounding piece 1. The compression member 3 is placed into the compression zone 12 from the opening on the upper side of the compression zone 12. It can be placed in one or both compression zones 12 according to actual needs. The opening of the compression zone 12 is provided with a third connecting strip 121 that connects to the inside of the surrounding piece 1. The third connecting strip 121 can connect to the outer wall of the compression zone 12 through the opening of the compression zone 12. The band 121 is connected to the outer wall of the compression area 12 by a hook and loop fastener 122. The hook and loop fastener 122 is existing technology and will not be described in detail here. After the compression member 3 is placed into the compression area 12, the third connecting band 121 can be tightened and the end of the third connecting band 121 is connected to the outer wall of the compression area 12 by the hook and loop fastener 122. This tightens the opening of the compression area 12, forming a blocking and limiting effect on the compression member 3, preventing the compression member 3 from sliding out of the opening of the compression area 12, and strengthening the limiting and fixing effect on the compression member 3.

[0018] like Figure 1-2 As shown, the first disconnection zone 11 has multiple tightening structures longitudinally arranged. Each tightening structure includes a first connecting strap 111 and a second connecting strap 112 connected to both ends of the surrounding piece 1. The outer side of the first connecting strap 111 has a Velcro closure 113, and the end of the second connecting strap 112 has a tightening buckle 114. One end of the first connecting strap 111 is wrapped around the tightening buckle 114. After the surrounding piece 1 is laid under the injured person's buttocks, both ends of the surrounding piece 1 wrap around the injured person's groin to form the first disconnection zone 11. The end of the first connecting strap 111 passes through the tightening buckle 114 and wraps back to the first connecting strap 111 to tighten the surrounding piece 1, thus ensuring that the surrounding piece 1 is tightly wrapped around the injured person's buttocks and groin, maintaining the restraint on the compression member 3. The first connecting strap 111 is positioned and fixed in that location. One end of the first connecting strap 111 is wrapped around the tightening buckle 114 and tightened, and then connected to the other end of the first connecting strap 111 via Velcro 113, so as to achieve quick fixation and quick disassembly of the surrounding piece 1, effectively improving the efficiency of hemostasis operation. Multiple tightening structures are provided longitudinally at the second disconnection area 21. The tightening structure at the second disconnection area 21 is consistent with the tightening structure at the first disconnection area 11. The tightening structure at the second disconnection area 21 is consistent with the tightening structure at the first disconnection area 11, so that the fixing piece 2 can be quickly fixed to the patient's thigh, forming a secondary reinforcement of the surrounding piece 1, and preventing the surrounding piece 1 and the pressure piece 3 from shifting and interfering with the pressure hemostasis during compression hemostasis.

[0019] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
