Description

Technical Field

[0001] The present invention relates to the technical field of medical first aid, and particularly relates to a rapid hemostasis device for pre-hospital first aid care. Background Art

[0002] Pre-hospital first aid care refers to the emergency medical rescue activities carried out by professional first aid personnel according to first aid principles and operating procedures when a patient has an accidental injury or sudden illness before the patient arrives at the hospital. Its purpose is to quickly evaluate the patient's condition, implement effective rescue measures, stabilize the patient's vital signs, prevent the condition from deteriorating, and create conditions for subsequent hospital treatment. This process plays a crucial role in improving the patient's survival rate and reducing the disability rate. During pre-hospital first aid care, if a certain part of the body is scratched and bleeding occurs, most patients will use medical supplies such as gauze for hemostasis operations.

[0003] When the existing hemostasis device uses gauze for hemostasis, relevant personnel need to wrap the gauze around the limbs and compress the blood vessels at the bleeding site for hemostasis treatment. Since the gauze needs to be manually wrapped and fixed by relevant personnel during fixation, the hemostasis efficiency is reduced and the hemostasis time is increased, thus further increasing the danger to the patient. Therefore, a rapid hemostasis device for pre-hospital first aid care is proposed. Summary of the Invention

The fixed rod moves into the fixing hole to quickly lock the position of the moving block. The limiting unit is used to limit the rotation direction of the extrusion roller. After that, the relevant personnel hold the tourniquet and tighten it. The extrusion roller limits the position of the tourniquet through the fixed cone, which can quickly compress the blood vessel, improve the hemostasis efficiency, and reduce the risk to the patient.

[0015] Second, in the present invention, the tourniquet drives the fixing cone to rotate, the fixing cone drives the extrusion roller to rotate, the extrusion roller drives the limiting gear ring to rotate on the limiting block, and the second inclined portion on the limiting gear ring fits with the first inclined portion on the limiting block to assist the limiting block to move on the limiting gear ring. After the tourniquet is tightened, the elastic potential energy of the second spring drives the square column and the limiting block to move downward, so that the limiting block limits the limiting gear ring to prevent the extrusion roller from reversing, which can further quickly compress the blood vessel.

[0037] As Figure 1 - Figure 14 shown, the embodiment of the present invention provides a rapid hemostasis device for pre-hospital emergency care, including a hemostasis component 1. The hemostasis component 1 includes an operation block 10, a hemostatic belt 11, a moving block 12, a plurality of conduction rollers 13, a pressing roller 14, a limit fixing mechanism 15, and a plurality of fixing cones 16. Among them, one side of the hemostatic belt 11 is arranged on the lower surface of the operation block 10, and the outer wall of the operation block 10 is respectively provided with a card slot 2 and a movable through slot 3. A moving through hole 7 is opened on the outer wall of the operation block 10. The card slots 2 are all communicated with the moving through hole 7 and the movable through slot 3. The outer wall of the moving block 12 fits on the inner wall of the card slot 2, and an operation groove 4 is opened on the upper surface of the moving block 12. A limit through hole 21 is opened on the inner bottom wall of the operation groove 4. The limit fixing mechanism 15 is arranged on the moving block 12, the operation block 10, and the pressing roller 14, and the limit fixing mechanism 15 passes through the movable through slot 3. The limit fixing mechanism 15 is used to quickly lock the position of the moving block 12 while limiting and fixing the position of the hemostatic belt 11 to ensure the effect of rapid hemostasis. Both ends of the plurality of conduction rollers 13 are rotatably connected to the inner wall of the operation groove 4, and both ends of the pressing roller 14 are rotatably connected to the inner wall of the operation groove 4. The pressing roller 14 is arranged above the corresponding conduction roller 13. The other side of the hemostatic belt 11 sequentially passes through the moving through hole 7 and the limit through hole 21, and the hemostatic belt 11 is in contact with both the pressing roller 14 and the plurality of conduction rollers 13. The plurality of fixing cones 16 are uniformly arranged on the outer wall of the pressing roller 14, and the plurality of fixing cones 16 are inserted into the hemostatic belt 11.

[0038] In this embodiment, specifically, the limit fixing mechanism 15 includes a U-shaped handle 150, a plurality of first springs 151, a square-shaped plate body 152, two limit units 153, and a fixing rod 154. Among them, the U-shaped handle 150 is arranged on the upper surface of the moving block 12, and the U-shaped handle 150 passes through the movable through groove 3. A U-shaped movable through hole 9 is formed in the upper surface of the moving block 12, and the outer wall of the square-shaped plate body 152 is slidably connected to the inner wall of the U-shaped movable through hole 9. The tops of the plurality of first springs 151 are uniformly arranged on the inner top wall of the U-shaped handle 150, and the bottoms of the plurality of first springs 151 are uniformly arranged on the upper surface of the square-shaped plate body 152. The two limit units 153 are symmetrically arranged on the square-shaped plate body 152 and the pressing roller 14. A fixing hole 20 is formed in the inner bottom wall of the card slot 2, and the outer wall of the fixing rod 154 is attached to the inner wall of the fixing hole 20. The top of the fixing rod 154 is arranged on the lower surface of the square-shaped plate body 152. Through the above settings, the relevant personnel hold and press the square-shaped plate body 152 to move close to the U-shaped handle 150. While the square-shaped plate body 152 drives the two limit units 153 to move, the square-shaped plate body 152 squeezes the first springs 151 to deform. The square-shaped plate body 152 drives the fixing rod 154 to move into the U-shaped movable through hole 9. Then, the relevant personnel hold the U-shaped handle 150 and the square-shaped plate body 152 to drive the moving block 12 to move into the card slot 2 of the operating block 10. The moving block 12 drives the tourniquet 11 to move into the moving through hole 7. After the relevant personnel release the square-shaped plate body 152 and the U-shaped handle 150, the elastic potential energy of the first springs 151 drives the square-shaped plate body 152, the limit units 153, and the fixing rod 154 to move downward. The fixing rod 154 moves into the fixing hole 20 to quickly lock the position of the moving block 12. The limit unit 153 is used to limit the rotation direction of the pressing roller 14 to further limit the position of the tourniquet 11.

[0039] In this embodiment, specifically, the limiting unit 153 includes a fixing plate 1530, a limiting block 1531, a limiting tooth ring 1532, a square column 1533, and a second spring 1534. Among them, the fixing plate 1530 is disposed on the inner wall of the U-shaped plate body 152, and a square through hole 25 is formed on the upper surface of the limiting unit 153. The outer wall of the square column 1533 is slidably connected to the inner wall of the square through hole 25, and the lower surface of the square column 1533 is disposed on the upper surface of the limiting block 1531. The limiting tooth ring 1532 is disposed on the outer wall of the pressing roller 14, and the second spring 1534 is in contact with the limiting tooth ring 1532. A first inclined portion 28 is formed on the outer wall of the limiting block 1531, and second inclined portions 29 are uniformly formed on the outer wall of the limiting tooth ring 1532. The first inclined portion 28 and the second inclined portions 29 are in contact with each other. Through the above settings, the tourniquet 11 drives the fixing cone 16 to rotate, the fixing cone 16 drives the pressing roller 14 to rotate, the pressing roller 14 drives the limiting tooth ring 1532 to rotate on the limiting block 1531, and the second inclined portions 29 on the limiting tooth ring 1532 are in contact with the first inclined portion 28 on the limiting block 1531, which is used to assist the limiting block 1531 to move on the limiting tooth ring 1532. After the tourniquet 11 is tightened, the elastic potential energy of the second spring 1534 drives the square column 1533 and the limiting block 1531 to move downward, so that the limiting block 1531 limits the limiting tooth ring 1532 to prevent the pressing roller 14 from rotating in reverse.

[0040] In this embodiment, specifically, a rubber pad 8 is disposed on the lower surface of the operation block 10. Through the above setting, the rubber pad 8 is used to increase the friction and comfort between the operation block 10 and the patient.

[0041] In this embodiment, specifically, limiting rods 5 are symmetrically disposed on the inner wall of the card slot 2, and limiting grooves 6 are symmetrically formed on the outer wall of the moving block 12. The outer wall of the limiting rod 5 is in contact with the inner wall of the limiting groove 6. Through the above setting, the limiting rod 5 moves into the limiting groove 6 to quickly position and move the moving block 12 into the card slot 2.

[0042] In this embodiment, specifically, steel balls 22 are uniformly embedded in the lower surface of the moving block 12, and the outer bottom wall of the steel balls 22 is in contact with the inner bottom wall of the card slot 2. Through the above setting, the steel balls 22 are used to assist the moving block 12 to move into the card slot 2.

[0043] In this embodiment, specifically, first sliding grooves 23 are symmetrically formed on the inner wall of the U-shaped movable through hole 9, and first sliding blocks 24 are symmetrically disposed on the outer wall of the U-shaped plate body 152. The outer wall of the first sliding block 24 is slidably connected to the inner wall of the first sliding groove 23. Through the above setting, the first sliding block 24 slides in the first sliding groove 23, which can not only assist the U-shaped plate body 152 to move, but also stabilize the position of the U-shaped plate body 152 during movement.

[0044] In this embodiment, specifically, second sliders 27 are uniformly arranged on the inner wall of the square through hole 25, second sliding grooves 26 are uniformly formed on the outer wall of the square column 1533, and the outer wall of the second slider 27 is slidably connected to the inner wall of the second sliding groove 26. By the above arrangement, the second slider 27 slides in the second sliding groove 26, which can not only assist the square column 1533 to move, but also stabilize the position of the square column 1533 during movement, thereby stabilizing the position of the limiting block 1531 during movement.

[0045] When the present invention is in operation: relevant personnel wind the tourniquet 11 around the upper part of the injured limb, and then the relevant personnel hold the extrusion mouth-shaped plate body 152 and move it close to the U-shaped handle 150. While the mouth-shaped plate body 152 drives the two fixing plates 1530 to move, the mouth-shaped plate body 152 squeezes the first spring 151 to deform. The mouth-shaped plate body 152 drives the fixing rod 154 to move into the U-shaped movable through hole 9, and then the relevant personnel hold the U-shaped handle 150 and the mouth-shaped plate body 152 to drive the moving block 12 to move into the card slot 2 of the operating block 10, and the moving block 12 drives the tourniquet 11 to move into the moving through hole 7.

[0046] The fixing plate 1530 drives the second spring 1534 and the square column 1533 to move upward through the elastic potential energy of the second spring 1534, so that the second spring 1534 is away from the limiting tooth ring 1532, which is used to release the position of the extrusion roller 14, facilitating the movement of the tourniquet 11, and the tourniquet 11 can be applied to the limbs of different patients.

[0047] After the relevant personnel release the mouth-shaped plate body 152 and the U-shaped handle 150, the elastic potential energy of the first spring 151 drives the mouth-shaped plate body 152, the fixing plate 1530 and the fixing rod 154 to move downward, and the fixing rod 154 moves into the fixing hole 20 to quickly lock the position of the moving block 12.

[0048] The fixing plate 1530 drives the limiting block 1531 to move onto the limiting gear ring 1532 through the second spring 1534. The elastic potential energy of the second spring 1534 drives the limiting block 1531 to closely fit with the limiting gear ring 1532. After that, the relevant personnel hold the tourniquet 11 and tighten it. The tourniquet 11 drives the fixing cone 16 to rotate. The fixing cone 16 drives the extrusion roller 14 to rotate. The extrusion roller 14 drives the limiting gear ring 1532 to rotate on the limiting block 1531. The second inclined portion 29 on the limiting gear ring 1532 fits with the first inclined portion 28 on the limiting block 1531, which is used to assist the limiting block 1531 to move on the limiting gear ring 1532. When the tourniquet 11 is tightened, the elastic potential energy of the second spring 1534 drives the square column 1533 and the limiting block 1531 to move downward, so that the limiting block 1531 limits the limiting gear ring 1532, which is used to prevent the extrusion roller 14 from reversing and can further quickly compress the blood vessel.

[0049] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
