Abstract
Description
Technical Field
[0001] This invention relates to the field of trauma hemostasis devices, specifically a trauma hemostasis device for use in the emergency department. Background Technology
[0002] Trauma hemostasis devices refer to various medical devices and materials used in the emergency department to manage bleeding in trauma patients. They are designed to quickly and effectively control, reduce, or completely stop ruptured blood vessels and blood loss caused by trauma through physical or chemical means. After trauma occurs, rapid and effective control of bleeding is the key to saving the patient's life. Trauma hemostasis devices can immediately block the source of bleeding by applying pressure, forming a barrier, promoting coagulation, or constricting blood vessels.
[0003] In emergency trauma care, hemostatic devices are crucial equipment. Timely hemostasis can reduce blood volume loss and maintain blood pressure and organ perfusion. When stopping bleeding, the hand or leg is usually bound on the side of the wound closer to the torso to achieve initial hemostasis. Then, gauze or other hemostatic devices are used to bandage the wound to stop the bleeding. However, when bandaging bleeding wounds at joints, it is difficult for the gauze to achieve a tight fit, resulting in some wounds not being hemostatically stopped, thus affecting the hemostatic effect.
[0004] Therefore, we propose an emergency department trauma hemostasis device to address the problems mentioned above. Summary of the Invention
[0005] The purpose of this invention is to provide an emergency department wound hemostasis device to solve the problem mentioned in the background art where it is difficult to achieve a tight fit when bandaging bleeding wounds at joints.

[0007] Preferably, two hooks are fixedly installed on one side of the outer wall of the portable frame, and a handle is fixedly installed on the other side of the outer wall of the portable frame.
[0008] Preferably, a first fixing plate is fixedly installed on the top right side of the leg rest, and a second fixing plate is fixedly installed on the top left side of the leg rest.
[0009] Preferably, the top of the second fixing plate is provided with a first strip hole, and one side of the outer wall of the second fixing plate is provided with a second strip hole.
[0010] Preferably, a gauze strap is fixedly installed on the top of the first fixing plate, and the other end of the gauze strap is movably inserted into the first and second strip holes.
[0011] Preferably, an inflatable airbag is fixedly installed on the top of the gauze strap, and a fixing sleeve is fixedly installed on the top of the gauze strap, with the top of the inflatable airbag being fixedly connected to the bottom of the fixing sleeve.
[0012] Preferably, the top of the inflatable airbag is fixedly provided with an inflation port, and the outer wall of the inflation port is fixedly inserted inside the fixed sleeve.
[0013] Preferably, an inflation tube is fixedly installed on the top of the inflation port, a one-way valve is fixedly installed on the outer wall of the inflation tube, a connecting strap is fixedly installed on the other end of the gauze strap, a rotating column is fixedly installed on the outer wall of the drive rod, and a connecting ring is fixedly installed on one side of the outer wall of the rotating column.
[0014] Preferably, a three-way pipe is fixedly installed on one side of the outer wall of the inflation tube, and an air inlet pipe is fixedly installed on one side of the outer wall of the three-way pipe, with the inlet end of the air inlet pipe fixedly inserted inside the inflation cylinder.
[0015] Preferably, two auxiliary compression airbags are fixedly installed on the outer wall of the inflatable airbag, two hoses are fixedly installed on the outer wall of the three-way tube, and the output ends of the two hoses are fixedly inserted into the interior of the two auxiliary compression airbags. Pressure valves are fixedly installed on the outer walls of the two hoses. An alarm is fixedly installed on the top of the portable frame, and an indicator light is fixedly installed on the top of the portable frame.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When the gauze bandage is initially applied to the bleeding site of the patient's joint, the forward and reverse motors are activated, causing the drive rod and gears to rotate. Then, under the action of the three connecting blocks and the limiting rod, the gear rack moves steadily upwards, which in turn moves the fixing rod and the sealing piston upwards inside the inflation cylinder. At this time, the one-way valve is open. When the sealing piston moves upwards, gas enters the inflation bladder along the air inlet pipe, inflation pipe, and inflation port. Because the inflation bladder is located between the fixing sleeve and the gauze bandage, and because the inflation bladder cannot expand upwards, the inflated bladder can adapt to the complex curved shape of the injured joint. The device should deform to ensure that the gauze bandage fits tightly and evenly against the wound. After the inflatable bladder reaches the predetermined pressure, the air drawn in by the inflator can open the pressure valves on the two hoses and enter the auxiliary compression bladder. This allows for layered or staged pressure control to apply pressure to the center of the wound using the inflatable bladder, and then to apply pressure to the surrounding area using the auxiliary compression bladder. This achieves comprehensive and continuous pressure control, rather than applying pressure only at a single point, thus improving the efficiency of hemostasis. This enhances the effectiveness of the emergency department trauma hemostasis device. The device can be carried in a vehicle or attached externally, and can be periodically released and pressurized to prevent ischemia and necrosis.
[0017] 2. When it is necessary to bandage and stop bleeding at the joint of the patient's leg, and the patient's leg is placed on the leg rest, one end of the gauze bandage and the connecting strap are passed through the first and second strip holes and fixed to the connecting ring. When the gear drives the gear rack to move upward and inflates the air bladder, its drive rod will also drive the rotating column to rotate towards the second fixed plate. Since the gauze bandage was initially taut at the injured area, when the air bladder squeezes the gauze bandage downward, the gauze bandage will loosen synchronously. This effectively avoids the initial gauze bandage becoming too taut due to the expansion of the air bladder, which could cause excessive pressure or discomfort to the patient's joint, and further improves the effectiveness of the trauma hemostasis device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-7 The present invention provides a technical solution: an emergency department trauma hemostasis device, comprising a leg support 1 and an adjustment assembly 2. The adjustment assembly 2 includes a portable frame 201, a forward / reverse motor 202 fixedly installed on the bottom inner wall of the portable frame 201, a drive rod 203 fixedly installed on one side of the outer wall of the forward / reverse motor 202, a gear 204 fixedly installed on the outer wall of the drive rod 203, a limiting plate 205 fixedly installed on the bottom inner wall of the portable frame 201, and the outer wall of the drive rod 203 movably inserted into the limiting plate 205. A concave frame 20 is fixedly installed on the bottom inner wall of the portable frame 201. 6. A limiting rod 207 is fixedly installed between the inner surface walls of the concave frame 206. Three connecting blocks 208 are movably sleeved on the outer surface wall of the limiting rod 207. A gear row 209 is meshed with the outer surface wall of the gear 204. One side of the outer wall of the gear row 209 is fixedly connected to the opposite side of the outer wall of the three connecting blocks 208. A fixing rod 210 is fixedly installed on the top of the gear row 209. A sealing piston 211 is fixedly installed on the top of the fixing rod 210. An air cylinder 212 is fixedly inserted into the top of the portable frame 201, and the outer surface wall of the sealing piston 211 is movably inserted into the inside of the air cylinder 212.
[0022] In this embodiment, when a doctor needs to bandage and stop the bleeding at a patient's injured leg joint, the leg is first bound on the side of the injured joint closer to the torso to achieve initial hemostasis and reduce blood flow. Then, the injured leg is placed on the leg support 1, with the bleeding joint positioned between the first fixation plate 3 and the second fixation plate 4. One end of the gauze bandage 7 is fixed to the top of the first fixation plate 3, and the other end is fitted with a connecting strap 13. The connecting strap 13 and one end of the gauze bandage 7 are then passed through the first slot 5 at the top of the second fixation plate 4, and then through the second slot 6 on one side of the outer wall of the second fixation plate 4. The connecting strap 13 and one end of the gauze bandage 7 are then secured using Velcro or other appropriate devices. The end is fixed to the connecting ring 15. Next, an inflatable airbag 8 is fixedly installed on the top of the gauze strap 7. A fixing sleeve 9 is fixedly installed on the top of the inflatable airbag 8, and the inflatable airbag 8 is located between the fixing sleeve 9 and the gauze strap 7. The fixing sleeve 9 has a fixed volume and will not expand, and the inflatable airbag 8 will not expand to the sides. Therefore, when the inflatable airbag 8 is inflated, it will only expand downwards. Then, an inflation port 10 is fixedly installed on the top of the inflatable airbag 8, and an inflation tube 11 is installed on the inflation port 10. At this time, the one-way valve 12 installed on the inflation tube 11 is in the closed state, and the other end of the inflation tube 11 is installed inside the inflation cylinder 212. The other end is connected to an air inlet tube through a three-way pipe 17. 18. To ensure a sealed installation, the air cylinder 212 has an air inlet with a one-way valve. When the sealing piston 211 forces the air from the air cylinder 212 into the airbag 8, it draws in outside air. Then, the external controller activates the forward / reverse motor 202 installed at the bottom of the inner wall of the portable frame 201, causing the drive rod 203 to rotate inside the limiting plate 205, which in turn drives the gear 204 to rotate. Since a concave frame 206 is installed at the bottom of the inner wall of the portable frame 201, and a limiting rod 207 is installed on the inner surface of the concave frame 206, the three connecting blocks 208 installed on one side of the outer wall of the gear rack 209 are movably fitted onto the limiting rod 207. Furthermore, the gear rack 209 and the gear 204... The components are meshed together, so that the rotation of gear 204, which rotates towards the second fixed plate 4, drives the gear rack 209 to move steadily upward at a uniform speed under the action of the three connecting blocks 208 and the limiting rod 207. A fixing rod 210 is fixedly installed on the top of the gear rack 209, and an air cylinder 212 passes through the top of the portable frame 201. A sealing piston 211 is fixedly installed on the top of the fixing rod 210. This sealing piston 211 can move like a piston inside the air cylinder 212. When the one-way valve 12 is opened, and the gear 204 drives the gear rack 209 to move steadily upward, it will also drive the fixing rod 210 and the sealing piston 211 to move upward inside the air cylinder 212.This allows gas to enter the inflatable airbag 8 via the air inlet tube 19, inflation tube 11, and inflation port 10. Since the inflatable airbag 8 is located between the fixing sleeve 9 and the gauze bandage 7, and the fixing sleeve 9 has a fixed volume, the inflatable airbag 8 cannot expand upwards or to the sides. Therefore, when gas enters the inflatable airbag 8, it compresses the gauze bandage 7. The inflated airbag 8 can adaptively deform according to the complex curved shape of the injured joint, ensuring that the gauze bandage 7 fits tightly and evenly against the wound. Furthermore, once the predetermined pressure is reached inside the inflatable airbag 8... The air drawn in by the air cylinder 212 can open the pressure valves 21 on the two hoses 20 and enter the auxiliary compression airbag 19. This allows for layered or staged pressure application to achieve comprehensive and continuous hemostasis, rather than applying pressure only to a single point, thus improving hemostasis efficiency. The device is automated, enhancing its effectiveness in emergency department wound hemostasis. The gauze can be replaced, and the device can be carried in a vehicle or attached externally. It can also be periodically relaxed and pressurized to prevent ischemia and necrosis.
[0023] like Figures 1-3 and Figure 6 , Figure 7As shown, two hooks 213 are fixedly installed on one side of the outer wall of the portable frame 201, and a handle 214 is fixedly installed on the other side of the outer wall of the portable frame 201. A first fixing plate 3 is fixedly installed on the top right side of the leg rest 1, and a second fixing plate 4 is fixedly installed on the top left side of the leg rest 1. A first strip hole 5 is opened on the top of the second fixing plate 4, and a second strip hole 6 is opened on one side of the outer wall of the second fixing plate 4. A gauze strap 7 is fixedly installed on the top of the first fixing plate 3, and the other end of the gauze strap 7 is movably inserted into the first strip hole 5 and the second strip hole 6. Inside hole 6, an inflatable airbag 8 is fixedly installed on the top of the gauze strap 7, and a fixing sleeve 9 is fixedly installed on the top of the gauze strap 7. The top of the inflatable airbag 8 is fixedly connected to the bottom of the fixing sleeve 9. An inflation port 10 is fixedly inserted into the top of the inflatable airbag 8, and the outer wall of the inflation port 10 is fixedly inserted into the inside of the fixing sleeve 9. An inflation tube 11 is fixedly installed on the top of the inflation port 10, and the input end of the inflation tube 11 is fixedly inserted into the inside of the inflation cylinder 212. A one-way valve 12 is fixedly installed on the outer wall of the inflation tube 11. The gauze strap 7... A connecting strap 13 is fixedly installed at the other end. A rotating column 14 is fixedly installed on the outer wall of the drive rod 203. A connecting ring 15 is fixedly installed on one side of the outer wall of the rotating column 14. An inflation tube 11 is fixedly installed at the top of the inflation port 10. A one-way valve 12 is fixedly installed on the outer wall of the inflation tube 11. A connecting strap 13 is fixedly installed at the other end of the gauze strap 7. A rotating column 14 is fixedly installed on the outer wall of the drive rod 203. A connecting ring 15 is fixedly installed on one side of the outer wall of the rotating column 14. A three-way pipe 17 is fixedly installed on one side of the outer wall of the inflation tube 11. An air inlet pipe 18 is fixedly installed on one side of the outer wall of the air bladder 212, and the input end of the air inlet pipe 18 is fixedly inserted into the inside of the air cylinder 212. Two auxiliary compression air bladders 19 are fixedly installed on the outer wall of the air bladder 8. Two hoses 20 are fixedly installed on the outer wall of the three-way pipe 17, and the output ends of the two hoses 20 are fixedly inserted into the inside of the two auxiliary compression air bladders 19. Pressure valves 21 are fixedly installed on the outer walls of the two hoses 20. An alarm 22 is fixedly installed on the top of the portable frame 201, and an indicator light 23 is fixedly installed on the top of the portable frame 201.
[0024] In this embodiment, an external controller, a human-machine interface, an alarm 22, an indicator light 23, and two pressure valves 21 are used in conjunction. The opening and closing of the two pressure valves 21 can be set as timed switches via the external controller and the human-machine interface. These, along with the opening of the forward and reverse motors 202, enable timed pressurization or deflation of the inflatable airbag 8 and the two auxiliary compression airbags 19. During pressurization or deflation, the alarm 22 will sound to alert the staff, and the indicator light 23 will use different colored lights to indicate the current status of the system, such as pressurizing, deflation, completed, or fault. Furthermore, this trauma hemostasis device can be used in vehicles and as an external stretcher attachment, increasing its versatility. The portable frame 201 provides protection for the internal structure and device. Two hooks 213 are installed on one side of the outer wall of the portable frame 201, allowing it to be hung in appropriate positions. After the patient's injured leg and joints are initially secured to the leg support 1... One end of the gauze bandage 7 and the connecting strap 13 pass through the first strip hole 5 and the second strip hole 6 and are fixed to the connecting ring 15. The connecting ring 15 is fixedly connected to the rotating column 14 fixedly installed on the drive rod 203. When the gear 204 drives the gear rack 209 to move upward and inflates the airbag 8 along the inflation tube 11 and the inflation port 10, the drive rod 203 will also drive the rotating column 14 to rotate towards the second fixing plate 4. Since the gauze bandage 7 was originally in the initial state at the injured joint of the patient, When the airbag 8 expands downwards and the gauze bandage 7 is fully and completely attached to the injured joint, the drive rod 203 drives the rotating column 14 and the connecting ring 15 to rotate towards the second fixing plate 4. This causes the gauze bandage 7 to retract along the second strip hole 6 and the first strip hole 5, and the gauze bandage 7 to loosen simultaneously. This effectively avoids the initial gauze bandage 7 from being overly tight due to the expansion of the airbag 8, which could cause excessive pressure or discomfort to the patient's joint, and further improves the effectiveness of the trauma hemostasis device.
[0025] The usage and working principle of this device are as follows: First, the leg is bound on the side of the injured joint closer to the torso to achieve initial hemostasis and reduce blood flow. Then, the injured leg is placed on the leg support 1, positioned at the injured joint. Next, the gauze bandage 7 is wrapped around the injured joint, and the connecting strap 13 and the gauze bandage 7 pass through the first strip hole 5 and the second strip hole 6 on the second fixing plate 4. The connecting strap 13 is then fixed to the connecting ring 15 installed on the top of the rotating column 14 using Velcro or appropriate tools. At this time, the gauze bandage 7 is taut at the wound site of the patient's joint. Immediately afterwards, one end of the inflation tube 11 is sealed to the inflation port 10 on the inflation airbag 8. At this time, the single... Valve 12 is closed, and the airbag 8 is partially inflated. The other end of the inflation tube 11 is then fixedly inserted into the air cylinder 212 to ensure a sealed connection. The air cylinder 212 is fixedly inserted into the top of the portable frame 201. Since the hemostasis is applied to the patient's joint, the gauze bandage 7 cannot fit tightly against the joint. Therefore, the external controller activates the forward and reverse motor 202 installed at the bottom of the inner wall of the portable frame 201, causing it to rotate the drive rod 203. This simultaneously drives the gear 204 and the rotating column 14 to rotate towards the second fixed plate 4. When the gear 204 rotates, a concave frame 206 is installed at the bottom of the inner wall of the portable frame 201, and three... Each connecting block 208 is movably fitted onto the limiting rod 207 installed on the inner wall of the concave frame 206, thereby allowing the gear 204 to drive the gear rack 209 to move stably upward. Since the fixing rod 210 is installed on the top of the gear rack 209, and the sealing piston 211 fixedly installed on the top of the fixing rod 210 is movably inserted into the air cylinder 212, the upward movement of the gear rack 209 causes the sealing piston 211 to move upward within the air cylinder 212. At this time, the one-way valve 12 installed on the inflation pipe 11 is open, allowing gas to enter the inflatable airbag 8 along the air inlet pipe 18, the inflation pipe 11, and the inflation port 10. Since the inflatable airbag 8 is installed above the gauze strap 7 and simultaneously below the fixing sleeve 9, then... The inflatable airbag 8 does not expand to either side during inflation. Since the fixing sleeve 9 has a fixed volume, when the inflatable airbag 8 expands, it only expands towards the gauze bandage 7. Furthermore, the inflated airbag 8 can adaptively deform according to the complex curved shape of the injured joint, ensuring a tight and even fit between the gauze bandage 7 and the wound. Once the predetermined pressure is reached inside the inflatable airbag 8, the air drawn in by its inflation cylinder 212 opens the pressure valves 21 on the two hoses 20 and enters the auxiliary compression airbag 19. This allows for layered or staged pressure application to stop bleeding, using the inflatable airbag 8 to compress the center of the wound and the auxiliary compression airbag 19 to compress the surrounding area.This device achieves comprehensive and continuous pressure hemostasis, improving the hemostatic effect. When the drive rod 203 drives the gear 204 to rotate towards the second fixed plate 4, it also drives the rotating column 14 to rotate towards the second fixed plate 4. This causes the rotating column 14 and the connecting ring 15 to rotate towards the second fixed plate 4, and the connecting strap 13 and the gauze bandage 7 to retract along the second strip hole 6 and the first strip hole 5. Since the gauze bandage 7 was initially taut at the injured joint, when the inflatable bladder 8 expands downwards and fully conforms to the injured joint, the gauze bandage 7 can simultaneously loosen. This effectively avoids excessive tension in the gauze bandage 7 caused by the expansion of the inflatable bladder 8, reducing excessive pressure or discomfort on the patient's joint. Overall, this improves the effectiveness of the trauma hemostasis device.
