[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 5 As shown, the utility model provides an emergency fixation device for limb bone injuries, including a fixed sleeve 1, in which a plurality of arc strips 2 are arranged, one end of the arc strip 2 is connected to a support rod 3, and the support rod 3 is connected to the fixed sleeve 1 through an elongation adjustment structure 4.

[0030] In another embodiment of the utility model, in order to facilitate the emergency placement of the limbs, the fixing sleeve 1 can be set to be open or composed of two parts, so as to facilitate the insertion of the patient's limbs when in use. In this embodiment, for the open structure or the case of being composed of two parts, it can be opened or closed by an active connection method such as a zipper or snaps.

[0031] The elongation adjustment structure 4 includes a sliding member 5 connected to the support rod 3 and an inflatable member 6 disposed in the fixed sleeve 1, wherein the inflatable member 6 includes an airbag block 61 abutting against the sliding member 5, one end of the airbag block 61 is connected to an air delivery pipe 62, and one end of the air delivery pipe 62 is connected to an air delivery control assembly 7;

[0032] The airbag block 61 is initially flat, the storage portion of the fixed sleeve 1 is used to accommodate the curved strip 2, and the movable portion of the fixed sleeve 1 is used for the sliding member 5 to slide freely in a straight line. The airbag block 61 is inflated through the air supply control component 7 to abut against the sliding member 5 for linear sliding, thereby pushing the curved strip 2 to support and fix the limb from different directions.

[0033] In the utility model, the positions of the various arc strips 2 in the fixing sleeve 1 are adjusted simultaneously by the extension adjustment structure 4, so as to realize rapid support and fixation of both ends of the affected part of the patient's limb, so as to avoid the situation in which the conventional fixation method causes the limbs to move or shake at both ends close to the bone injury area, thereby aggravating the patient's bone injury due to the cumbersome fixation steps.

[0034] The fixing sleeve 1 is usually a rectangular parallelepiped or a cylinder, and the inner cavity of the fixing sleeve 1 for the affected limb to pass through is usually cylindrical. In order to ensure the fixing effect of the fixing sleeve 1 on both ends of the affected part of the patient's limb, no less than 3 curved strips 2 are arranged in the fixing sleeve 1, and the force in the direction of at least 3 curved strips 2 is sufficient to ensure a firm fixing effect on both ends of the affected part of the patient's limb.

[0035] In order to realize the ability of the elongation adjustment structure 4 to adjust each arc strip 2 at the same time, the utility model is completed by the combined use of the inflatable member 6 and the sliding member 5. The inflatable member 6 is commonly an airbag block, and the common material of the airbag block is a tough rubber material. The sliding member 5 is fixedly connected to the arc strip 2 through the support rod 3, and the air supply control component 7 inflates each airbag block 61 through each air supply pipe 62. Each airbag block 61 is gradually filled from a flat state, thereby pushing the sliding member 5 abutting against the airbag block 61 to slide, thereby pushing the position of each arc strip 2 relative to the fixed sleeve 1 to change simultaneously.

[0036] The inflatable member in this embodiment can be inflated using a conventional inflator, and the specific inflation method is not limited in this embodiment.

[0037] In order to facilitate the patient's limb affected ends to be inserted into the fixing sleeve 1 without being bumped by the curved strips 2, thereby preventing the limbs from moving or shaking at both ends near the bone injury area, the utility model provides a preferred solution, a storage groove 11 for accommodating the curved strips 2 is provided in the fixing sleeve 1, a through groove 12 is provided on one side of the storage groove 11, and the support rod 3 passes through the through groove 12.

[0038] Before the present invention is worn, each curved strip 2 is pushed into the storage slot 11, and the storage slot 11 can ensure that the curved strip 2 has no exposed part, so that the fixed sleeve 1 is in a tubular structure state, so that the patient can easily extend the two ends of the affected part of the limb into the fixed sleeve 1.

[0039] Furthermore, a sliding cavity 13 is provided at one end of the through groove 12, and the sliding cavity 13 is sleeved outside the sliding member 5. The airbag block 61 is provided in the sliding cavity 13, and one end of the airbag block 61 abuts against the sliding member 5. The size of the sliding member 5 is larger than the size of the through groove 12 to ensure that the sliding member 5 can only slide freely in the space of the sliding cavity 13. The sliding member 5 pushes the support rod 3 to move freely in a straight line in the sliding cavity 13 along the straight line direction of the sliding cavity 13.

[0040] In order to prevent the arc strip 2 placed in the storage slot 11 from falling off and bumping against the affected part of the patient's limb, a magnetic component 8 is provided in the fixed sleeve 1 to facilitate the placement of the arc strip 2. The magnetic component 8 includes a first magnetic block 81 arranged on the non-contact surface of the arc strip 2 and a second magnetic block 82 arranged in the storage slot 11, and the first magnetic block 81 is directly opposite to the second magnetic block 82. The magnitude of the mutual attraction magnetic force generated between the first magnetic block 81 and the second magnetic block 82 is smaller than the magnitude of the thrust generated when the inflatable member 6 is filled, so as to ensure that the magnetic component 8 does not affect the adjustment of the arc strip 2 by the inflatable member 6 while ensuring the fixing of the arc strip 2.

[0041] In order to realize the simultaneous inflation of each inflatable member 6, the utility model provides a preferred solution, the gas delivery control assembly 7 includes a ventilation pipe 71 arranged in the fixed sleeve 1 and an inflation joint 72 connected to the ventilation pipe 71, the inflation joint 72 passes through the fixed sleeve 1, a one-way valve 73 is arranged on one side of the inflation joint 72, the ventilation pipe 71 is provided with a plurality of openings 74, the openings 74 correspond to the gas delivery pipe 62 one by one, and the gas delivery pipe 62 is fixedly connected to the ventilation pipe 71 through the openings 74. The inflation joint 72 is used to connect to an electric inflation pump to ensure inflation efficiency.

[0042] When the gas enters the adjacent inflatable parts 6 in sequence along the ventilation tube 71, it pushes the curved strips 2 corresponding to each inflatable part 6 to abut against the two ends of the affected part of the patient's limb. As the gas in each inflatable part 6 gradually approaches the upper limit of the filling adapted to the individual, each curved strip 2 reaches a suitable fixing force for the two ends of the affected part of the patient's limb.

[0043] Furthermore, in order to avoid the discomfort of the patient caused by over-inflation of the inflatable member 6 during operation or to return the utility model to its original position after use, the ventilation tube 71 is connected to an exhaust valve 75. The reset operation of the utility model opens the exhaust valve 75 and pushes each arc strip 2 to press the gas in each inflatable member 6 so that it is completely discharged.

[0044] In order to reduce the pain caused by the curved strip 2 contacting and fixing the affected part of the patient's limb at both ends, a buffer layer is provided on the side where the curved strip 2 contacts the affected part of the patient's limb. The common filling material of the buffer layer is a sponge pad or filled cotton.

[0045] In another embodiment of the present invention, in order to facilitate observation, the material of the present invention can be made transparent to facilitate observation when it is fixed.

[0046] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
