Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a hemostatic device for internal bleeding caused by war trauma and a method of using the device. Background Art

[0002] In combat trauma, it is mainly caused by the kinetic energy transfer of high-speed projectiles (such as bullets, explosion fragments). According to the kinetic energy theorem (E = 1 / 2mv 2 ), the square of the projectile velocity is positively correlated with the injury energy, and its terminal velocity depends on the shooting 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 the permanent cavity effect, that is, the fixed injury channel formed by the bullet or explosive fragments directly penetrating the chest and / or abdomen; the other is the temporary cavity effect caused by the explosion shock wave, which causes the surrounding tissue to be squeezed and torn. These two effects often lead to rupture of large 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, the area of ​​​​combat trauma wounds is not large, but the depth of the wound is long, and it is difficult to determine the specific injury.

[0003] In battlefield settings, the time from injury to professional treatment is a key factor in determining a soldier's survival rate. If medical intervention is received within one hour, with a focus on controlling active bleeding, treatment outcomes can be significantly improved, reducing the risk of wound infection. However, if treatment is delayed beyond 12 or even 24 hours, the risk of intra-abdominal infection increases significantly, potentially threatening the soldier's life.

[0004] Currently, most methods and / or devices for stopping bleeding from war wounds to internal organs rely on physical compression hemostasis. First, gauze is stuffed into the wound, and then a hemostatic bandage is tied to the proximal end of the wound to achieve compression hemostasis. However, most of these methods can only stop bleeding from surface wounds and are difficult to effectively stop bleeding from internal organs. Summary of the Invention

[0005] The present invention provides a hemostatic device for treating internal bleeding caused by combat trauma and its use method. A compression belt and binding straps secure the entire hemostatic device to the patient. The silicone outer shell and silicone capsule of the compression assembly are placed through the wound in the patient's body. A filling device controls the silicone capsule's inflated state to physically compress and stop bleeding at the site of internal bleeding. Simultaneously, a hydrogel sealant prepared using a hydrogel preparation assembly is used to stop bleeding at the site of internal bleeding. The hemostatic device is easy to operate, highly efficient, and effective, addressing the challenges of the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, the first injection assembly and the second injection assembly each include an injection cylinder and a piston assembly, the inlet and outlet ends of the two injection cylinders are connected by a tee, and the two ends of the tee connecting the two injection cylinders are relatively horizontally arranged, and the other end of the tee is connected to a second conduit, and the second conduit flows out of the end away from the tee for hemostasis at the location 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 tubes with first through holes, and the end of the second conduit away from the three-way pipe is connected to the several diversion tubes through a diversion valve; the lower side and side wall of the silicone jacket are provided with second through holes that are arranged to cooperate with the first through holes.

[0010] Furthermore, the base plate is fixedly connected to two connecting seats, and the two connecting seats are respectively connected to connecting sleeves adjustably through threads. The first conduit and the second conduit are respectively slidably passed through the two connecting seats and the connecting sleeves. The inner side of the connecting sleeve is connected to a plurality of cooperating rubber petals, one end of the rubber petal is fixedly connected to the inner side wall of the connecting sleeve, and the other end of the rubber petal abuts against the outer side 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 base plate is connected to an adjusting bolt through 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 is passed through the silicone capsule.

[0012] Furthermore, the hydrogel type A agent is four-arm polyethylene glycol, and the hydrogel type B agent is a mixture of polyethylene imine and adipic acid dihydrazide; the four-arm polyethylene glycol is mixed with the mixture of polyethylene imine and adipic acid 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 carbohydrazide-modified gelatin; the monoaldehyde-modified hyaluronic acid and the carbohydrazide-modified gelatin are mixed to obtain an injectable hydrogel sealant that is hydrolyzable in an alkaline environment.

[0014] Furthermore, the filling device is a water injection pump, and the silicon capsule is a water injection balloon.

[0016] A method for using a hemostatic device for internal bleeding caused by war trauma, comprising the following steps:

[0017] S1. Store hydrogel type A inside the first injection assembly and hydrogel type B inside the second injection assembly. Connect the inlet and outlet ends of the first injection assembly and the second injection assembly via a tee, with the other end of the tee connected to the diverter valve via a second conduit. Connect the filling device to the silicone capsule via the first conduit.

[0018] S2. Insert the silicone jacket into the body through the wound and secure the entire hemostatic device to the patient's body using a compression belt and a bandage.

[0019] S3. Turn the adjusting bolt to make the lower outer wall of the silicone jacket contact the location of internal bleeding;

[0020] S4. Press the linkage plate to squeeze out the hydrogel type A in the first injection assembly and the hydrogel type B in the second injection assembly. The hydrogel type A and the hydrogel type B are mixed in the three-way pipe and / or the second conduit and / or the diverter valve and / or the diverter pipe to form a hydrogel sealant. The hydrogel sealant flows out through the first through hole and the second through hole to stop bleeding at the site of internal bleeding.

[0023] S7. Use the filling device to control the silicone capsule to be in an unfilled state, then remove it together with the silicone jacket, finally remove the hemostatic device and suture the skin wound.

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

[0025] 1. The present invention provides a hemostatic device for visceral bleeding caused by war trauma. The base plate is fixed to the patient's body surface by a compression belt and a strap, and combined with the in vivo positioning of the silicone jacket, an internal and external dual fixation system is formed. Even if the patient is in a moving state (such as during transportation), the device can still remain stable to avoid hemostatic failure caused by displacement; and the physical compression of the silicone capsule (volume expansion after filling) and the chemical blocking of the hydrogel sealant form a dual hemostatic effect. After filling, the silicone capsule can directly compress the visceral bleeding points and quickly reduce blood flow; at the same time, the hydrogel A / B type agent quickly solidifies after mixing, forming a physical barrier to seal the bleeding wound. The dual effect significantly improves the hemostatic efficiency.

[0026] 2. The present invention provides a hemostatic device for internal bleeding caused by war trauma. The push-pull rods of the piston assemblies of the first injection assembly and the second injection assembly are connected by a linkage plate. When the linkage plate is pressed, the movement strokes of the piston assemblies of the first injection assembly and the second injection assembly are made the same, and the hydrogel type A agent / hydrogel type B agent (volume ratio is 1:1) are extruded at the same time, which simplifies the operation steps and shortens the battlefield first aid time. The outlet ends of the injection barrels of the first injection assembly and the second injection assembly are connected by a three-way pipe, and the three-way pipe connects the injection barrels of the first injection assembly and the second injection assembly. The two ends of the cylinder are relatively horizontally arranged, so that the extruded hydrogel type A agent and hydrogel type B agent impact and mix with each other in the three-way pipe (the hydrogel type A agent is extruded from left to right in the horizontal direction, and the hydrogel type B agent is extruded from right to left in the same horizontal direction). After that, the resulting hydrogel sealant is fully mixed and then extruded through the second conduit along the other (vertical) connecting end of the three-way pipe, thereby further improving the mixing effect of the hydrogel type A agent and the hydrogel type B agent. The resulting hydrogel sealant has a reasonable ratio, good hemostatic effect and high hemostatic efficiency at the site of visceral bleeding.

[0027] 3. The present invention provides a hemostasis device for combat traumatic internal bleeding. Several shunt tubes with first through-holes are connected to the underside of a silicone capsule. A second conduit is connected to the several shunt tubes via a shunt valve. Second through-holes cooperating with the first through-holes are provided on the underside and sidewalls of the silicone outer sleeve. This allows the hydrogel type A in the first injection assembly and the hydrogel type B in the second injection assembly to be extruded and mixed in the three-way tube and / or the second conduit and / or the shunt valve and / or the shunt tube, further enhancing the mixing effect of the hydrogel type A and hydrogel type B. Finally, the hydrogel sealant flows out through the first and second through-holes. The hydrogel sealant is evenly distributed, enabling it to cover a larger bleeding area. This device is suitable for use on wounds with multiple bleeding spots or irregular wound surfaces.

[0028] 4. The present invention provides a hemostasis device for visceral bleeding caused by war trauma, in which a connecting seat is connected to a base plate, the connecting seat is connected to a connecting sleeve, and the inner side of the connecting sleeve is connected to a rubber flap, which can achieve the effect of the first catheter and / or the second catheter being inserted into the connecting sleeve and passing through, and being sealed when withdrawn; the silicone outer cylinder is connected to the base plate by an adjusting bolt, and the relative position of the silicone outer sleeve and the base plate can be adjusted by the adjusting bolt, so that the silicone outer sleeve can fully contact the internal organs, thereby making the entire device adaptable to different clinical needs and improving the hemostasis effect; at the same time, the adjusting bolt is passed through the silicone capsule, and the adjusting bolt guides the filling process of the silicone capsule, so that the silicone capsule is evenly filled and enlarged in all directions, thereby improving the uniformity and stability of the physical pressure on the internal organ hemostasis position.

[0029] 5. The present invention provides a hemostatic device for visceral bleeding caused by war trauma. The hydrogel type A agent is four-arm polyethylene glycol, and the hydrogel type B agent is a mixture of polyethyleneimine and adipic acid dihydrazide. The hydrogel sealant obtained by mixing the two uses aldehyde-terminated four-arm polyethylene glycol (PEG) as a crosslinker, which can effectively adjust 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 crosslinker to form a sealant through a Schiff base reaction. The hydrogel has a good hemostatic effect and can achieve controllable degradation without mechanical debridement or surgical resection. The hydrogel type A agent is a monoaldehyde-modified hyaluronic acid (HA- mCHO), HA-mCHO is formed by chemically modifying the hyaluronic acid (HA) molecular chain to introduce an aldehyde group (-CHO). Hyaluronic acid is a natural extracellular matrix component with good biocompatibility and water retention. The hydrogel type B agent is carbohydrazide-modified gelatin (GL-CDH). After gelatin is modified with carbohydrazide (CDH), a hydrazide group (-NH-NH-C(=O)-) is introduced into the molecular chain to form GL-CDH. Gelatin is a hydrolysis product of collagen and has thermoreversible gel properties. The prepared hydrogel sealant is stable under acidic or neutral conditions, but can be hydrolyzed in an alkaline environment. The hydrogel sealant also has good self-healing ability. After use, weak alkaline water can be injected through a second catheter to quickly degrade the hydrogel sealant. After the silicone capsule is vented / watered out, the volume is reduced, making it easier to remove the device as a whole and reducing secondary stimulation to the wound surface. This is in line with the principle of "rapid intervention and rapid evacuation" in battlefield first aid.

[0030] 6. This invention provides a hemostatic device for combat traumatic internal bleeding. The filling device (water injection pump / air pump) precisely controls the filling level of the silicone capsule (water-filled balloon / air balloon), preventing tissue damage caused by excessive compression. The elastic design of the silicone outer shell ensures more even pressure distribution, reducing the risk of localized pressure ulcers and making it particularly suitable for hemostasis of fragile internal organs.

10. A method for using a hemostatic device for internal bleeding caused by war trauma, wherein the hemostatic device according to claim 5 is used to stop hemorrhage caused by internal bleeding caused by war trauma; The following steps are involved: S1. Store hydrogel type A inside the first injection assembly and hydrogel type B inside the second injection assembly. Connect the inlet and outlet ends of the first injection assembly and the second injection assembly via a tee, with the other end of the tee connected to the diverter valve via a second conduit. Connect the filling device to the silicone capsule via the first conduit. S2. Insert the silicone jacket into the body through the wound and secure the entire hemostatic device to the patient's body using a compression belt and a bandage. S3. Turn the adjusting bolt to make the lower outer wall of the silicone jacket contact the location of internal bleeding; S4. Press the linkage plate to squeeze out the hydrogel type A in the first injection assembly and the hydrogel type B in the second injection assembly. The hydrogel type A and the hydrogel type B are mixed in the three-way pipe and / or the second conduit and / or the diverter valve and / or the diverter pipe to form a hydrogel sealant. The hydrogel sealant flows out through the first through hole and the second through hole to stop bleeding at the site of internal bleeding. S5. Start the filling device to fill the silicone capsule, apply pressure to the internal bleeding site to stop bleeding, and squeeze and smooth the hydrogel sealant. S6. After hemostasis of the internal organs is completed, the three-way tube and the second catheter are removed and separated, and weak alkaline water is injected through the second catheter to rapidly degrade the hydrogel sealant; S7. Use the filling device to control the silicone capsule to be in an unfilled state, then remove it together with the silicone jacket, finally remove the hemostatic device and suture the skin wound.
