Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device for stopping bleeding from internal organs caused by combat trauma and its method of use. Background Technology

[0002] In combat trauma, the primary cause is the transfer of kinetic energy from high-speed projectiles (such as bullets and explosive fragments). According to the kinetic energy theorem (E = ... 1 / 2mv 2 In combat, the square of the projectile velocity is positively correlated with the wounding energy, and its terminal velocity depends on the firing distance, initial velocity, and projectile shape. When a projectile penetrates the human body, the high-speed kinetic energy causes two typical types of tissue damage: one is a permanent cavity effect, i.e., a fixed damage channel formed when the bullet or explosive fragments directly penetrate the chest and / or abdomen; the other is a temporary cavity effect caused by the blast wave, resulting in compression and tearing of surrounding tissues. Both of these effects often lead to rupture of major blood vessels or solid internal organs (such as the liver, spleen, and kidneys) in the chest and / or abdomen, causing fatal blood loss. Therefore, in most cases, combat wounds are small in area but long in depth, and the specific injury is difficult to determine.

[0003] In a battlefield environment, the time from injury to receiving professional treatment is a critical factor determining the survival rate of the wounded. If medical intervention can be received within 1 hour, with the focus on controlling active bleeding, the treatment effect can be significantly improved and the risk of trauma infection reduced. However, if the delay is 12 hours or even 24 hours, the risk of abdominal infection will increase significantly, and may even directly affect the life of the wounded.

[0004] Currently, the methods and / or devices for stopping bleeding in internal organs from combat trauma are mostly physical compression hemostasis. First, gauze dressings are used to pack the wound, and then a hemostatic bandage is tied to the proximal end of the wound to achieve the effect of compression hemostasis. However, most of these methods can only stop bleeding on the surface wound and are difficult to effectively stop bleeding in internal organs. Summary of the Invention

[0005] This invention aims to provide a hemostatic device for internal bleeding in combat trauma and its method of use. The entire hemostatic device is fixed to the wounded soldier using compression bands and straps. The silicone outer shell and silicone capsule of the compression component are placed inside the wound. An inflation device controls the silicone capsule to be inflated, providing physical compression to stop the bleeding at the site of internal bleeding. Simultaneously, a hydrogel sealant is prepared using a hydrogel preparation component to stop the bleeding at the site of internal bleeding. The hemostatic operation is convenient, and the hemostatic efficiency and effect are high, solving the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for stopping visceral bleeding in combat trauma includes a base plate with compression bands connected to its left and right sides, each compression band connected to a strap. It also includes a compression assembly and a hydrogel preparation assembly. The compression assembly includes a silicone jacket, a silicone capsule, and an inflation device. The silicone jacket is elastic and adjustablely connected to the lower side of the base plate. The silicone capsule is disposed inside the silicone jacket and is detachably connected to the inflation device via a first conduit. The inflation device controls the inflation state of the silicone capsule. The hydrogel preparation assembly includes a first injection assembly and a second injection assembly. The first injection assembly stores a hydrogel type A agent, and the second injection assembly stores a hydrogel type B agent. The hydrogel type A agent and the hydrogel type B agent are mixed to obtain a hydrogel sealant for stopping bleeding at the site of visceral bleeding.

[0008] Furthermore, both the first injection assembly and the second injection assembly include an injection barrel and a piston assembly. The inlet and outlet ends of the two injection barrels are connected by a three-way tube, and the two ends of the three-way tube connecting the two injection barrels are arranged horizontally relative to each other. The other end of the three-way tube is connected to a second catheter, and a hydrogel sealant flows out from the end of the second catheter away from the three-way tube for hemostasis at the site of visceral bleeding. The push-pull rods of the two piston assemblies are connected by a linkage plate.

[0009] Furthermore, the lower side of the silicone capsule is connected to several diversion pipes with first through holes, and the end of the second conduit away from the three-way pipe is connected to several diversion pipes through a diversion valve; the lower side and sidewall of the silicone outer shell are provided with second through holes that cooperate with the first through holes.

[0010] Furthermore, the substrate is fixedly connected to two connecting seats, and each of the two connecting seats is adjustablely connected to a connecting sleeve via a thread. The first conduit and the second conduit are slidably inserted through the two connecting seats and the connecting sleeves, respectively. A plurality of mating rubber flaps are connected to the inner side of the connecting sleeve. One end of the rubber flap is fixedly connected to the inner wall of the connecting sleeve, and the other end of the rubber flap abuts against the outer wall of the first conduit and / or the second conduit.

[0011] Furthermore, the inner bottom wall of the silicone jacket is connected to a universal ball assembly, and the substrate is connected to an adjusting bolt via a thread; the lower end of the adjusting bolt is connected to the rotating ball of the universal ball assembly, and the bolt body of the adjusting bolt passes through the silicone capsule.

[0012] Further, the hydrogel type A agent is tetra-arm polyethylene glycol, and the hydrogel type B agent is a mixture of polyethyleneimine and adipate dihydrazide; the tetra-arm polyethylene glycol is mixed with the mixture of polyethyleneimine and adipate dihydrazide to obtain an injectable and degradable hydrogel sealant.

[0013] Furthermore, the hydrogel type A agent is monoaldehyde-modified hyaluronic acid, and the hydrogel type B agent is carbazide-modified gelatin; the monoaldehyde-modified hyaluronic acid and the carbazide-modified gelatin are mixed to obtain an injectable hydrogel sealant that can be hydrolyzed in an alkaline environment.

[0014] Furthermore, the filling device is a water injection pump, and the silicone capsule is a water injection balloon. After the water injection balloon is filled with water, its external volume increases, and it expands the silicone outer shell to squeeze and stop the bleeding at the site of internal organ bleeding.

[0015] Furthermore, the inflation device is an air pump, and the silicone capsule is a balloon bladder. After the balloon bladder is inflated, its volume increases, and it expands the silicone outer shell to compress and stop the bleeding at the site of internal organ bleeding.

[0016] A method for using a hemostatic device for internal bleeding in combat trauma, comprising the following steps:

[0017] S1. Store hydrogel type A agent inside the first injection component, store hydrogel type B agent inside the second injection component, and connect the inlet and outlet ends of the first injection component and the second injection component using a three-way tube, and connect the other end of the three-way tube to the diversion valve through the second conduit; connect the filling device to the silicone capsule using the first conduit.

[0018] S2. Insert the silicone sheath into the body through the wound, and use compression bands and straps to fix the entire hemostatic device to the patient's body.

[0019] S3. Rotate the adjusting bolt to bring the lower outer wall of the silicone sleeve into contact with the location of internal bleeding.

[0020] S4. Press the linkage plate to squeeze out the hydrogel type A agent in the first injection component and the hydrogel type B agent in the second injection component. The hydrogel type A agent and the hydrogel type B agent are mixed in the three-way tube and / or the second conduit and / or the diversion valve and / or the diversion tube to obtain the hydrogel sealant. The hydrogel sealant flows out through the first through hole and the second through hole to stop bleeding at the site of visceral bleeding.

[0021] S5. Start the filling device to fill the silicone capsule, apply pressure to the bleeding site of the internal organ to stop the bleeding, and at the same time squeeze and smooth the hydrogel sealant.

[0022] S6. After hemostasis of internal organs is completed, disassemble the three-way stopcock and the second catheter, and use the second catheter to inject weak alkaline water to rapidly degrade the hydrogel sealant.

[0023] S7. Use the filling device to keep the silicone capsule in an unfilled state, then remove it along with the silicone outer shell, and finally remove the hemostatic device and suture the skin wound.

[0024] The beneficial effects of the technical solution are:

[0025] 1. This invention provides a hemostatic device for visceral bleeding in combat trauma. The base plate is fixed to the patient's body surface by compression bands and straps, combined with the internal positioning of the silicone capsule, forming a dual fixation system. Even when the patient is moving (e.g., during transport), the device remains stable, avoiding hemostatic failure due to displacement. Furthermore, it utilizes the physical compression of the silicone capsule (volume expansion after inflation) and the chemical sealing of the hydrogel sealant to achieve a dual hemostatic effect. After inflation, the silicone capsule can directly compress the visceral bleeding point, rapidly reducing blood flow; simultaneously, the hydrogel A / B type agents, after mixing, quickly solidify, forming a physical barrier to seal the bleeding wound. This dual action significantly improves hemostatic efficiency.

[0026] 2. This invention provides a hemostatic device for internal bleeding in combat trauma. The push-pull rods of the piston assemblies of the first and second injection components are connected by a linkage plate. When the linkage plate is pressed, the piston assemblies of the first and second injection components move at the same distance, simultaneously extruding hydrogel type A agent / hydrogel type B agent (volume ratio 1:1). This simplifies the operation and shortens battlefield first aid time. The outlet ends of the injection cylinders of the first and second injection components are connected by a three-way pipe, and the three-way pipe connects the injection ports of the first and second injection components. The two ends of the cylinder are set horizontally relative to each other, so that the extruded hydrogel type A agent and hydrogel type B agent are mixed by mutual impact in the three-way tube (hydrogel type A agent is extruded from left to right in the horizontal direction, and hydrogel type B agent is extruded from right to left in the same horizontal direction). After the hydrogel sealant is fully mixed, it is extruded through the second conduit along the other (vertical) connecting end of the three-way tube, which further improves the mixing effect of hydrogel type A agent and hydrogel type B agent. The resulting hydrogel sealant has a reasonable ratio and good hemostatic effect and high hemostatic efficiency for internal bleeding sites.

[0027] 3. The present invention provides a hemostatic device for internal bleeding in combat trauma, wherein a plurality of shunt tubes with first through holes are connected to the lower side of a silicone capsule, and a second conduit is connected to the plurality of shunt tubes through a shunt valve. The lower side and sidewall of the silicone jacket are provided with second through holes that cooperate with the first through holes, so that the hydrogel type A agent in the first injection component and the hydrogel type B agent in the second injection component are squeezed out and mixed in the three-way tube and / or the second conduit and / or the shunt valve and / or the shunt tube, further improving the mixing effect of the hydrogel type A agent and the hydrogel type B agent. Finally, the hydrogel sealant flows out through the first through hole and the second through hole. The hydrogel sealant is evenly distributed, so that it can cover a larger bleeding area, which is suitable for multiple bleeding points or irregular wounds.

[0028] 4. The present invention provides a hemostatic device for visceral bleeding in combat trauma. A connecting seat is connected to a base plate, and a connecting sleeve is connected to the connecting seat. A rubber flap is connected to the inner side of the connecting sleeve. The rubber flap can achieve the effect of penetration when the first catheter and / or the second catheter are inserted into the connecting sleeve and sealing when withdrawn. The silicone outer cylinder is connected to the base plate by adjusting bolts. The relative position of the silicone outer cylinder and the base plate can be adjusted by adjusting bolts, so that the silicone outer cylinder can make full contact with the viscera, thereby making the entire device adaptable to different clinical needs and improving the hemostatic effect. At the same time, the adjusting bolts are inserted into the silicone capsule, and the adjusting bolts guide the filling process of the silicone capsule, so that the silicone capsule fills evenly and expands in all directions, improving the uniformity and stability of physical pressure on the visceral hemostasis position.

[0029] 5. This invention provides a hemostatic device for internal bleeding in combat trauma. The hydrogel type A agent is tetra-arm polyethylene glycol (PEG), and the hydrogel type B agent is a mixture of polyethyleneimine and adipic acid dihydrazide. The resulting hydrogel sealant uses aldehyde-terminated tetra-arm PEG as a crosslinking agent, which can effectively regulate the performance of the hydrogel sealant and use it as a hemostatic sealant. The mixed amino component composed of polyethyleneimine (PEI) and adipic acid dihydrazide (ADH) reacts with the aldehyde component of the PEG crosslinking agent via a Schiff base reaction to form a sealant. This hydrogel has good hemostatic effect and achieves controllable degradation without mechanical debridement or surgical resection. The hydrogel type A agent is monoaldehyde-modified hyaluronic acid (HA-). HA-mCHO is formed by chemically modifying the hyaluronic acid (HA) molecular chain by introducing aldehyde groups (-CHO). Hyaluronic acid is a natural extracellular matrix component with good biocompatibility and water retention. The hydrogel type B agent is hydrazine-modified gelatin (GL-CDH). After modification with hydrazine (CDH), hydrazine groups (-NH-NH-C(=O)-) are introduced into the molecular chain of gelatin to form GL-CDH. Gelatin is a hydrolysis product of collagen and has thermally reversible gel properties. The prepared hydrogel sealant is stable under acidic or neutral conditions but can undergo hydrolysis in alkaline environments. Furthermore, the hydrogel sealant has good self-healing ability. After use, the hydrogel sealant can be rapidly degraded by injecting weakly alkaline water through a second catheter. Combined with the silicone capsule for venting / draining, the volume is reduced, facilitating the overall removal of the device and reducing secondary irritation to the wound, conforming to the principle of "rapid intervention and rapid evacuation" in battlefield emergency treatment.

[0030] 6. This invention provides a hemostatic device for internal bleeding in combat trauma. The inflation device (water pump / air pump) can precisely control the inflation degree of the silicone capsule (water-filled balloon / balloon balloon), avoiding excessive pressure that could cause tissue damage. The elastic design of the silicone jacket makes the pressure distribution more uniform, reducing the risk of local pressure sores, and is especially suitable for hemostasis of fragile internal organs.

After the balloon bladder is inflated, its volume increases, and it expands the silicone outer shell to squeeze and stop the bleeding at the site of internal organ bleeding.

6. A hemostatic device for internal bleeding in combat trauma according to claim 1, characterized in that, The method of using this device includes: S1. Store hydrogel type A agent inside the first injection component, store hydrogel type B agent inside the second injection component, and connect the inlet and outlet ends of the first injection component and the second injection component using a three-way tube, and connect the other end of the three-way tube to the diversion valve through the second conduit; connect the filling device to the silicone capsule using the first conduit. S2. Insert the silicone sheath into the body through the wound, and use compression bands and straps to fix the entire hemostatic device to the patient's body. S3. Rotate the adjusting bolt to bring the lower outer wall of the silicone sleeve into contact with the location of internal bleeding. S4. Press the linkage plate to squeeze out the hydrogel type A agent in the first injection component and the hydrogel type B agent in the second injection component. The hydrogel type A agent and the hydrogel type B agent are mixed in the three-way tube and / or the second conduit and / or the diversion valve and / or the diversion tube to obtain the hydrogel sealant. The hydrogel sealant flows out through the first through hole and the second through hole to stop bleeding at the site of visceral bleeding. S5. Start the filling device to fill the silicone capsule, apply pressure to the bleeding site of the internal organ to stop the bleeding, and at the same time squeeze and smooth the hydrogel sealant. S6. After hemostasis of internal organs is completed, disassemble the three-way stopcock and the second catheter, and use the second catheter to inject weak alkaline water to rapidly degrade the hydrogel sealant. S7. Use the filling device to keep the silicone capsule in an unfilled state, then remove it along with the silicone outer shell, and finally remove the hemostatic device.
