Description

Technical Field

[0001] This invention relates to the field of medical emergency technology, and in particular to a rapid hemostasis device for pre-hospital emergency care. Background Technology

[0002] Pre-hospital emergency care refers to the emergency medical care activities carried out by professional emergency personnel before the patient arrives at the hospital when the patient suffers an accidental injury or sudden illness, in accordance with emergency principles and operating procedures. Its purpose is to quickly assess 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 emergency care, if a part of the body is scratched and bleeding occurs, the patient will usually use gauze and other medical supplies to stop the bleeding.

[0003] When existing hemostatic devices use gauze for hemostasis, personnel need to wrap the gauze around the limbs and compress the blood vessels at the bleeding site to stop the bleeding. Since the gauze needs to be wrapped and secured manually, the efficiency of hemostasis is reduced and the time required for hemostasis is increased, thereby further increasing the risk to the patient. Therefore, a rapid hemostatic device for pre-hospital emergency care is proposed. Summary of the Invention

[0004] In view of this, the present invention aims to provide a rapid hemostasis device for pre-hospital emergency care to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] In some embodiments, the limiting and fixing mechanism includes a U-shaped handle, a plurality of first springs, a U-shaped plate, two limiting units, and a fixing rod. The U-shaped handle is disposed on the upper surface of the movable block and passes through the movable through slot. A U-shaped movable through hole is formed on the upper surface of the movable block, and the outer wall of the U-shaped plate is slidably connected to the inner wall of the U-shaped movable through hole. The top ends of the plurality of first springs are evenly disposed on the inner top wall of the U-shaped handle, and the bottom ends of the plurality of first springs are evenly disposed on the upper surface of the U-shaped plate.

The top end of the fixing rod is disposed on the lower surface of the U-shaped plate.

[0007] In some embodiments, the limiting unit includes a fixing plate, a limiting block, a limiting toothed ring, a square column, and a second spring. The fixing plate is disposed on the inner wall of the U-shaped plate, and the upper surface of the limiting unit has a square through hole. The outer wall of the square column is slidably connected to the inner wall of the square through hole, and the lower surface of the square column is disposed on the upper surface of the limiting block. The limiting toothed ring is disposed on the outer wall of the extrusion roller, and the second spring is in contact with the limiting toothed ring. The outer wall of the limiting block has a first inclined portion, and the outer wall of the limiting toothed ring has a second inclined portion uniformly disposed, with the first inclined portion and the second inclined portion in contact with each other.

[0013] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0014] I. This invention involves moving a U-shaped plate close to a U-shaped handle by hand. Simultaneously, the U-shaped plate moves two limiting units and a fixing rod into the U-shaped movable through-hole. Then, the U-shaped handle moves a moving block into the slot of the operating block, and the moving block moves the tourniquet into the movable through-hole. Afterward, when the person releases the U-shaped plate and U-shaped handle, the elastic potential energy of the first spring causes the U-shaped plate, limiting units, and fixing rod to move downward. The fixing rod moves into the fixing hole to quickly lock the position of the moving block. The limiting units limit the rotation direction of the squeezing roller. The person then tightens the tourniquet, and the squeezing roller, through the fixing cone, limits the position of the tourniquet, quickly compressing the blood vessel, improving hemostasis efficiency, and reducing patient risk.

[0015] II. In this invention, the tourniquet drives the fixed cone to rotate, the fixed cone drives the compression roller to rotate, and the compression roller drives the limiting toothed ring to rotate on the limiting block. The second inclined part on the limiting toothed ring is in contact with the first inclined part on the limiting block to assist the limiting block in moving on the limiting toothed ring. When 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 toothed ring to prevent the compression roller from reversing, and can further and quickly compress the blood vessel.

[0037] like Figure 1 - Figure 14 As shown, this embodiment of the invention provides a rapid hemostasis device for pre-hospital emergency care, including a hemostasis component 1. The hemostasis component 1 includes an operating block 10, a tourniquet 11, a movable block 12, several transmission rollers 13, a compression roller 14, a limiting and fixing mechanism 15, and several fixing cones 16. One side of the tourniquet 11 is disposed on the lower surface of the operating block 10, and the outer wall of the operating block 10 is provided with a slot 2 and a movable through groove 3. A movable through hole 7 is also provided on the outer wall of the operating block 10. The slots 2 are all connected to the movable through hole 7 and the movable through groove 3. The outer wall of the movable block 12 is fitted to the inner wall of the slot 2, and an operating groove 4 is provided on the upper surface of the movable block 12. A limiting through hole 21 is provided on the inner bottom wall of the operating groove 4. The limiting and fixing mechanism 15 is disposed on the movable block 10. The tourniquet 11 is positioned on block 12, operating block 10, and squeezing roller 14, with limiting and fixing mechanism 15 passing through movable through groove 3. Limiting and fixing mechanism 15 is used to quickly lock the position of moving block 12 while limiting and fixing the position of tourniquet 11 to ensure rapid hemostasis. Both ends of several transmission rollers 13 are rotatably connected to the inner wall of operating groove 4, and both ends of squeezing roller 14 are rotatably connected to the inner wall of operating groove 4. Squeezing roller 14 is positioned above the corresponding transmission roller 13. The other side of tourniquet 11 passes through movable through hole 7 and limiting through hole 21 in sequence, and tourniquet 11 is in contact with squeezing roller 14 and several transmission rollers 13. Several fixing cones 16 are evenly arranged on the outer wall of squeezing roller 14, and several fixing cones 16 are inserted into tourniquet 11.

[0038] In this embodiment, specifically, the limiting and fixing mechanism 15 includes a U-shaped handle 150, several first springs 151, a U-shaped plate 152, two limiting units 153, and a fixing rod 154. The U-shaped handle 150 is disposed on the upper surface of the moving block 12 and passes through the movable through slot 3. A U-shaped movable through hole 9 is provided on the upper surface of the moving block 12, and the outer wall of the U-shaped plate 152 is slidably connected to the inner wall of the U-shaped movable through hole 9. Several first springs... The top ends of springs 151 are evenly distributed on the inner top wall of the U-shaped handle 150, and the bottom ends of several first springs 151 are evenly distributed on the upper surface of the U-shaped plate 152. Two limiting units 153 are symmetrically distributed on the U-shaped plate 152 and the extrusion roller 14. The inner bottom wall of the slot 2 is provided with a fixing hole 20, and the outer wall of the fixing rod 154 is attached to the inner wall of the fixing hole 20. The top end of the fixing rod 154 is distributed on the lower surface of the U-shaped plate 152. Through the above arrangement... Personnel hold and press the U-shaped plate 152 close to the U-shaped handle 150 and move it. Simultaneously, the U-shaped plate 152 moves the two limiting units 153, compressing the first spring 151 and causing deformation. The U-shaped plate 152 then moves the fixed rod 154 into the U-shaped movable through hole 9. Then, personnel hold the U-shaped handle 150 and the U-shaped plate 152, moving the moving block 12 into the slot 2 of the operating block 10. The moving block 12... When the tourniquet 11 moves into the movable through hole 7, and the relevant personnel release it from the U-shaped plate 152 and the U-shaped handle 150, the elastic potential energy of the first spring 151 drives the U-shaped plate 152, the limiting unit 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 movable block 12. The limiting unit 153 is used to limit the direction of rotation of the squeezing roller 14, further restricting 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 toothed ring 1532, a square column 1533, and a second spring 1534. The fixing plate 1530 is disposed on the inner wall of the U-shaped plate 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 toothed ring 1532 is disposed on the outer wall of the extrusion roller 14, and the second spring 1534 is in contact with the limiting toothed ring 1532. A first inclined portion 28 is formed on the outer wall of the limiting block 1531, and a series of evenly spaced features are formed on the outer wall of the limiting toothed ring 1532. The second inclined portion 29, the first inclined portion 28, and the second inclined portion 29 are in contact with each other. The tourniquet 11 is set up to drive the fixed cone 16 to rotate. The fixed cone 16 drives the compression roller 14 to rotate. The compression roller 14 drives the limiting tooth ring 1532 to rotate on the limiting block 1531. The second inclined portion 29 on the limiting tooth ring 1532 is in contact with the first inclined portion 28 on the limiting block 1531 to assist the limiting block 1531 in moving on the limiting tooth 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 tooth ring 1532 to prevent the compression roller 14 from reversing.

[0040] In this embodiment, specifically, a rubber pad 8 is provided on the lower surface of the operating block 10. The rubber pad 8 is provided to increase the friction and comfort between the operating block 10 and the patient.

[0041] In this embodiment, specifically, the inner wall of the slot 2 is symmetrically provided with limiting rods 5, and the outer wall of the moving block 12 is symmetrically provided with limiting grooves 6. The outer wall of the limiting rod 5 is attached to the inner wall of the limiting groove 6. By setting the limiting rod 5 as described above, it moves into the limiting groove 6, which is used to quickly position and move the moving block 12 into the slot 2.

[0042] In this embodiment, specifically, steel balls 22 are uniformly embedded on 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 slot 2. The steel balls 22 are used to assist the moving block 12 in moving into the slot 2.

[0043] In this embodiment, specifically, the inner wall of the U-shaped movable through hole 9 is symmetrically provided with a first sliding groove 23, and the outer wall of the U-shaped plate 152 is symmetrically provided with a first slider 24. The outer wall of the first slider 24 is slidably connected to the inner wall of the first sliding groove 23. By the above arrangement, the first slider 24 can slide in the first sliding groove 23, which can both assist the U-shaped plate 152 to move and stabilize the position of the U-shaped plate 152.

[0044] In this embodiment, specifically, the inner wall of the square through hole 25 is uniformly provided with a second slider 27, and the outer wall of the square column 1533 is uniformly provided with a second sliding groove 26. 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 in moving, but also stabilize the position of the square column 1533, thereby stabilizing the position of the limiting block 1531.

[0045] When the invention is in operation: the relevant personnel wrap the tourniquet 11 around the injured limb, and then the relevant personnel hold and squeeze the U-shaped plate 152 close to the U-shaped handle 150 and move it. At the same time, the U-shaped plate 152 drives the two fixed plates 1530 to move, and the U-shaped plate 152 squeezes the first spring 151 to deform. The U-shaped plate 152 drives the fixed rod 154 to move into the U-shaped movable through hole 9. Then the relevant personnel hold the U-shaped handle 150 and the U-shaped plate 152 to move the moving block 12 into the slot 2 of the operating block 10. The moving block 12 drives the tourniquet 11 to move into the movable through hole 7.

[0046] The fixed plate 1530 uses the elastic potential energy of the second spring 1534 to drive the second spring 1534 and the square column 1533 to move upward, so that the second spring 1534 moves away from the limiting toothed ring 1532, which is used to release the position of the squeezing roller 14, making it convenient to move the position of the tourniquet 11, and the tourniquet 11 can be applied to the limbs of different patients.

[0047] Afterwards, the relevant personnel release the U-shaped plate 152 and the U-shaped handle 150. The elastic potential energy of the first spring 151 drives the U-shaped plate 152, the fixing plate 1530 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.

[0048] The fixed plate 1530, via the second spring 1534, moves the limiting block 1531 onto the limiting toothed ring 1532. The elastic potential energy of the second spring 1534 causes the limiting block 1531 to fit tightly against the limiting toothed ring 1532. Then, a person holds the tourniquet 11 and tightens it. The tourniquet 11 causes the fixed cone 16 to rotate, which in turn causes the compression roller 14 to rotate. The compression roller 14 then causes the limiting toothed ring 1532 to rotate on the limiting block 1531. The second inclined portion 29 on the ring 1532 fits against the first inclined portion 28 on the limiting block 1531, which is used to assist the limiting block 1531 in moving on the limiting toothed 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 toothed ring 1532 to prevent the compression roller 14 from reversing, and can further and quickly compress the blood vessel.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
