Description

Technical Field

[0001] This invention relates to the field of trauma hemostasis technology, specifically a trauma hemostasis device for use in the emergency department. Background Technology

[0002] In the daily work of the emergency department, wound hemostasis is an extremely critical and common emergency procedure. Bleeding caused by trauma is complex and varied, and rapid and effective hemostasis is essential to saving patients' lives and reducing the incidence of complications.

[0003] A search of existing trauma hemostasis devices and methods revealed that the relevant technologies mainly fall into the following categories:

[0004] 1. Traditional tourniquets: such as rubber tourniquets, which block blood flow by wrapping the limb in a loop and tightening it.

[0005] 2. Inflatable tourniquet: It uses an inflatable balloon to generate pressure for hemostasis, which is an improvement in pressure control compared to the traditional tourniquet.

[0006] 3. Hemostatic dressing combined with compression device: Hemostasis is achieved by using a dressing with hemostatic function (such as hemostatic gauze, hemostatic powder, etc.) combined with a mechanical compression device.

[0007] Patent publication number CN214907663U discloses a utility model relating to the field of medical technology, specifically to a trauma hemostasis device for emergency departments. The device includes a hemostasis frame with a grid-like fixing frame at the top and an opening in the middle. An air bladder is located on the inner wall of the frame, and a conduit connecting the air bladder to a medical rubber ball is provided on the frame. A Velcro strap is located at the bottom of the air bladder, and hemostatic cotton is located at the bottom of the Velcro strap. Movable fasteners and mounting plates are connected to both sides of the hemostasis frame. Both the movable fasteners and the mounting plates have rotating shafts, and these shafts connect an elastic bandage to the movable fasteners and the mounting plates via a rotating rod. This utility model solves the problems of existing hemostasis bandages being unsuitable for wound hemostasis where foreign objects cannot be removed, and the bandages being prone to loosening, making it suitable for widespread use.

[0008] Patent publication number CN210871858U discloses a tourniquet for limbs, comprising a rectangular block with two threaded holes. A fastening post is threadedly connected to the inner wall of each threaded hole. A rotating knob is fixedly connected to one end of the fastening post, and a compression mechanism is rotatably connected to the other end. Stabilizing blocks are connected to both sides of the rectangular block via a connecting mechanism. An arc-shaped block is fixedly connected to the bottom of the stabilizing block, and an arc-shaped groove is formed at the bottom of the arc-shaped block. A bandage is fixedly connected to the side wall of the stabilizing block, and a tensioning mechanism is provided on the bandage. When treating a wound, the rectangular block is placed on the wound, and the bandage provides fastening. The stabilizing block, arc-shaped block, T-groove, and T-block work together to separate the rectangular block from the skin, providing protection. Rotating the fastening post, combined with the action of the universal ball bearing and the compression block, quickly stops bleeding from the wound.

[0009] Patent publication number CN220757439U discloses a hemostasis, bandaging, and fixation device, including a pressure bandaging pad. The pressure bandaging pad contains two airbags connected by a connecting pipe. The lower airbag is connected to an inflation / deflation mechanism. A proximal inflatable tourniquet is connected to the lower end of the pressure bandaging pad, and the tourniquet is equipped with a combination buckle and a winch. An inflation / deflation mechanism is also connected to the right end of the tourniquet. Fastening straps are located at both ends of the pressure bandaging pad, and a fixing rod slot is located in the middle of the pad. A telescopic fixing rod is inserted into the fixing rod slot. This utility model, with its integrated structure, is mainly used for temporary external fixation of open wounds on the limbs and torso in disaster emergency care, preventing secondary injuries during transport. A single person can quickly complete the hemostasis, bandaging, and fixation operations, improving disaster relief capabilities and making it worthy of promotion.

[0010] Currently, while existing hemostatic devices can all achieve hemostasis for patient injuries, traditional hemostatic devices do not take into account changes in patient body temperature and ambient temperature. Some injured patients may experience a drop in body temperature due to massive bleeding when they are sent to the emergency department. When the core body temperature is <36℃, platelet adhesion function decreases, aggregation ability weakens, coagulation factor activity decreases, PT and APTT are prolonged, fibrinogen synthesis is inhibited, and fibrinolytic activity is enhanced. Studies have shown that a low temperature of 34℃ can increase blood loss by 20%. In this case, traditional hemostatic devices reduce the hemostatic effect. Summary of the Invention

[0011] (a) Technical problems to be solved

[0012] To address the shortcomings of existing technologies, this invention provides a trauma hemostasis device for emergency departments, which solves the problem that traditional hemostasis devices do not take into account changes in patient body temperature and ambient temperature. Some injured patients may experience a drop in body temperature due to massive bleeding when they are sent to the emergency department, which reduces the hemostasis effect.

[0022] (III) Beneficial Effects

[0023] This invention provides a trauma hemostasis device for use in the emergency department. It has the following beneficial effects:

[0024] 1. This invention involves activating a second suction pump, which draws water from a constant-temperature water tank through a second suction pipe. The water then enters the constant-temperature film bag through a fourth suction pipe to maintain the temperature at the wound site. Simultaneously, the first suction pump is activated, and the first water valve on the first suction pipe is opened, drawing water from the constant-temperature film bag through the first suction pipe. Finally, the water enters the constant-temperature water tank, ensuring that the water inside the constant-temperature film bag remains at a constant temperature, close to the optimal point for thrombin reaction (approximately 37°C). This accelerates platelet aggregation and fibrin formation. This method is safe and efficient, minimizes tissue damage, and speeds up hemostasis.

[0025] 2. In this invention, the second pump is started, and the second pump draws warm saline from the saline tank through the third pumping pipe. The warm saline enters the interior of the constant temperature film bag through the fourth pumping pipe. At the same time, the solenoid valve is opened, and the warm saline inside the constant temperature film bag flows through the outlet pipe onto the hemostatic gauze strip, which applies pressure to the wound to stop bleeding, thus facilitating rapid hemostasis for the injured person.

[0026] 3. In this invention, when treating a patient's wound for hemostasis, the hemostatic gauze strip is first placed close to the constant temperature film bag, and the third and fourth hook and loop fasteners are glued together to fix the hemostatic gauze strip. Then, the hemostatic gauze strip is attached to the wound, and the inflatable hemostatic bag and the hemostatic gauze strip are fixed to the wound by the first and second fixing straps. The first and second hook and loop fasteners are glued together, which allows the first and second fixing straps to be glued together. By adjusting the glued position of the first and second hook and loop fasteners, it can be applied to fixation at different wound sites. Attached Figure Description

Water inside the constant temperature film bag 2 is extracted through the first liquid extraction pipe 17. Finally, the water enters the interior of the constant temperature water storage tank 19, so that the water inside the constant temperature film bag 2 is always kept at a constant temperature.

[0040] A second pumping assembly is connected between the constant temperature water tank 19 and the brine tank 20. The second pumping assembly includes a second pumping pump 21, the inlet of which is fixedly connected to a second pumping pipe 22.

A fourth water valve 27 is fixedly installed on the outer surface of the fourth liquid extraction pipe 26. When the second water valve 24 on the second liquid extraction pipe 22 and the fourth water valve 27 on the fourth liquid extraction pipe 26 are opened, the second liquid extraction pump 21 is started. The second liquid extraction pump 21 draws water from the constant temperature water storage tank 19 through the second liquid extraction pipe 22.

At the same time, the solenoid valve 30 is opened, and the warm saline inside the constant temperature film bag 2 flows to the hemostatic gauze strip 3 through the water outlet pipe 29.

[0042] Working principle:

[0043] When treating a patient's wound for hemostasis, first place the hemostatic gauze strip 3 close to the constant temperature film bag 2, and let the third hook and loop fastener 8 and the fourth hook and loop fastener stick together to fix the hemostatic gauze strip 3. Then, attach the hemostatic gauze strip 3 to the wound and fix the inflatable hemostatic bag 1 and the hemostatic gauze strip 3 to the wound through the first fixing strap 4 and the second fixing strap 6. The first hook and loop fastener 5 and the second hook and loop fastener 7 are glued together, which can make the first fixing strap 4 and the second fixing strap 6 glued together. By adjusting the glued position of the first hook and loop fastener 5 and the second hook and loop fastener 7, it can be used to fix different wounds.

[0044] The water temperature is heated to 40-60℃ by the heating device in the constant temperature water tank 19 (adjusted according to the patient's body temperature and ambient temperature). The temperature is maintained at a constant temperature by the temperature controller and temperature sensor. The second water valve 24 on the second drainage pipe 22 and the fourth water valve 27 on the fourth drainage pipe 26 are opened, and the second drainage pump 21 is started. The second drainage pump 21 draws water from the constant temperature water tank 19 through the second drainage pipe 22. The water enters the constant temperature film bag 2 through the fourth drainage pipe 26 to maintain the temperature of the wound. At the same time, the first drainage pump 16 is started, and the first water valve 18 on the first drainage pipe 17 is opened. Water is drawn from the constant temperature film bag 2 through the first drainage pipe 17. Finally, the water enters the constant temperature water tank 19, so that the water inside the constant temperature film bag 2 is always kept at a constant temperature.

[0045] By continuously squeezing and pressing the airbag 10, the air inside the airbag 10 enters the inflatable hemostatic airbag 1 through the first air supply pipe 9, causing the inflatable hemostatic airbag 1 to inflate and expand, thereby squeezing the wound and making the hemostatic gauze strip 3 fit tightly to the wound. By opening the exhaust valve 15, the air inside the inflatable hemostatic airbag 1 can be discharged through the exhaust pipe 14, changing the pressure of the inflatable hemostatic airbag 1 on the wound.

[0046] In some cases, warm saline gauze is needed for pressure hemostasis. The water temperature is heated to 50-60℃ by the heating device in the saline tank 20 (adjusted according to the patient's body temperature and ambient temperature). Warm saline gauze pressure hemostasis at 50-60℃ is the best choice, as this temperature is close to the optimal point for thrombin reaction (about 37℃). The temperature is maintained at a constant temperature by the temperature controller and temperature sensor. The third water valve 25 on the third drainage pipe 23 and the fourth water valve 27 on the fourth drainage pipe 26 are opened, and the second drainage pump 21 is started. The second drainage pump 21 draws warm saline from the saline tank 20 through the third drainage pipe 23. The warm saline enters the interior of the constant temperature film bag 2 through the fourth drainage pipe 26. At the same time, the solenoid valve 30 is opened, and the warm saline inside the constant temperature film bag 2 flows to the hemostatic gauze strip 3 through the outlet pipe 29 to apply pressure to the wound for hemostasis. The hemostatic gauze strip 3 is replaced according to the amount of water seepage on it.
