[0001] The invention relates to the technical field of fracture fixators, in particular to an emergency fixator for limb fractures and a use method thereof. Background Art

[0002] Once a limb fracture occurs due to external reasons such as car accidents and construction, it must be fixed immediately to prevent the fracture ends from further displacement, thereby avoiding further damage to blood vessels and nerves around the fracture. Timely and effective fixation can not only reduce pain and relieve the patient's symptoms, but also create favorable conditions for subsequent surgical treatment and significantly reduce the incidence of complications.

[0003] However, most fracture fixation splints currently on the market are large in size and weight, which is not only inconvenient to carry, but also takes up space, and is obviously not suitable for preventive carrying and use in emergency situations.

[0004] In addition, existing fracture fixation splints have relatively simple functions and cannot provide cold compresses while fixing the fracture. Cold compresses can not only help reduce swelling, but also relieve pain, improve blood circulation, and provide a better basis for subsequent treatment. However, since most fixation splints do not consider these additional functions, patients can only use ice packs and other equipment alone, which increases the complexity of first aid treatment.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: See also Figure 1-Figure 7 , an emergency fixator for limb fractures, comprising a support plate 1 and a support plate 2 arranged adjacently, such as Figure 1 As shown, the sides of pallet 1 and pallet 2 are provided with straps 3. When in use, pallet 1 and pallet 2 are unfolded and laid flat, and the fractured limb is placed on pallet 1 and pallet 2. Then, pallet 1 and pallet 2 can be tied and fixed to the limb by straps 3 to ensure that the fractured part is firmly supported and fixed. The straps 3 can be fixed by Velcro.

[0021] like Figure 3 As shown, pallet 1 and pallet 2 are connected by a soft bag 7, allowing pallet 1 and pallet 2 to be folded or unfolded. When folded, the overall device is smaller in size, convenient for carrying and storage, and can be unfolded and laid flat when needed.

[0022] like Figure 4As shown, a storage cavity 5 is formed inside the support plate 1 for storing salt (such as ammonium chloride), and a water cavity 6 is formed inside the support plate 2 for storing water. Figure 5 As shown, one end of the soft bag 7 is provided with a mounting tube 1 8, which is screwed into a mounting groove 1, which is provided on the side of the storage cavity 5, and the other end of the soft bag 7 is provided with a mounting tube 2 9, which is screwed into a mounting groove 2, which is provided on the side of the water cavity 6. In addition, the interior of the soft bag 7 is separated by a diaphragm 10; When the diaphragm 10 is not broken, the salt and water are separated and do not react; when the diaphragm 10 is broken, the storage chamber 5 and the water chamber 6 are connected, so that the water and the salt are mixed, and low temperature is generated through endothermic reaction, thereby achieving the effect of cold compress, helping to relieve swelling and reduce pain.

[0023] like Figure 4 As shown, the water chamber 6 is connected with the liquid chamber 12 through the infusion channel 11. A piston 13 is movably arranged in the liquid chamber 12. A push rod 14 is fixedly installed on the piston 13. The end of the push rod 14 extends to the outside of the support plate 2 and is fixedly connected to a push plate 15. By pushing the push plate 15, the piston 13 can be driven to move through the push rod 14. The movement of the piston 13 fills the water in the liquid chamber 12 into the water chamber 6. Since the volume of the water chamber 6 is limited, the water will break through the diaphragm 10, thereby connecting the storage chamber 5 and the water chamber 6.

[0024] like Figure 2 As shown, an airbag cushion 4 is also laid on the pallet 1 and the pallet 2, which can be inflated. In addition, a connecting rod 16 is fixedly installed on the side of the push plate 15 facing the pallet 2, and a movable plug 17 is fixedly installed at the end of the connecting rod 16. The movable plug 17 is movably arranged in an air cavity 18. The air cavity 18 is opened in the pallet 2 and communicated with the airbag cushion 4 through the air groove; When the push plate 15 is pushed, the movable plug 17 is also driven to move through the connecting rod 16. The movement of the movable plug 17 fills the gas in the air cavity 18 into the airbag cushion 4 through the air groove, so that the airbag cushion 4 is inflated and bulged. The bulged airbag cushion 4 can provide comfortable support and reduce the pressure on the fracture site, thereby improving the comfort and safety during the first aid process.

[0025] like Figure 4 As shown, a cross bar 19 is fixedly installed on the other side of the piston 13, and the cross bar 19 is movably inserted in the cross groove and provided with a seal to keep the cross groove sealed. A rod groove 20 for inserting the cross bar 19 is provided on the side of the support plate 1 facing the support plate 2; When the push plate 15 is pushed to move the piston 13, the piston 13 also drives the cross bar 19 to move. The cross bar 19 moves its end to insert into the rod groove 20. By inserting into the rod groove 20, the support plate 1 and the support plate 2 can be connected as a whole to avoid relative rotation, thereby ensuring the fixation effect on the fracture.

[0026] In this embodiment, Figure 7 As shown, the end of the crossbar 19 is provided with a tail sleeve 21, and the tail sleeve 21 has a large friction force on the crossbar 19. The end of the tail sleeve 21 is provided with a magnetic block 22, and the inner wall of the rod groove 20 is provided with a magnetic block 23 that attracts the magnetic block 22; When the cross bar 19 moves, the tail sleeve 21 is inserted into the rod groove 20, thereby connecting the pallet 1 and the pallet 2 as a whole; if it is necessary to fix the joint and there is no need to connect the pallet 1 and the pallet 2 as a whole, you can use your fingers to block the cross groove when pushing the push plate 15, so that the cross bar 19 will go deeper into the tail sleeve 21 when moving, and will no longer push out the tail sleeve 21, so that the pallet 1 and the pallet 2 remain independent.

[0027] In the present invention, the movement of the piston 13 in the liquid chamber 12 and the movement of the moving plug 17 in the air chamber 18 both have a large friction force, thereby achieving the purpose of self-positioning, and can also automatically adapt to the swelling of the fracture site. When the fracture site swells, the airbag cushion 4 is squeezed and can automatically lose air, thereby causing the moving plug 17, the connecting rod 16 and the push plate 15 to move in the opposite direction; Since the magnet block 1 22 and the magnet block 23 will attract each other after the tail sleeve 21 is inserted into the rod groove 20, even if the push plate 15 and the cross bar 19 move in the opposite direction, it will not affect the connection between the support plate 1 and the support plate 2, thereby ensuring the stability of the structure and not affecting the fracture fixation effect.

[0028] Embodiment 2: Based on the first embodiment, this embodiment proposes a method for using a limb fracture emergency fixator, which specifically includes the following steps: Step 1: unfold and lay the pallet 1 and the pallet 2 flat; Step 2: placing the fractured limb on the support plate 1 and the support plate 2; Step 3: Use the strap 3 to tie and fix the support plate 1 and the support plate 2 to the limb; Step 4: Push the push plate 15 to connect the support plate 1 and the support plate 2 2 together, and at the same time inflate the airbag cushion 4.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
