[0002] At present, in the emergency treatment of limb trauma of orthopedic patients, the injured part of the patient needs to be bandaged. In order to prevent the patient from moving randomly after the fracture, the injured part needs to be fixed to reduce the pain of the injured and the damage to the surrounding tissues. Most of the existing fixation devices are of a fixed model and cannot be adjusted. Therefore, different types of fixation devices are needed for different patients, which takes up too much space on the one hand and increases the cost on the other.

[0003] To solve the above problems, a Chinese patent with publication number CN211325959U discloses an emergency fixation device for orthopedic limb trauma, including a support seat, two pressure seats are arranged above the support seat, the top of the support seat and the bottom of the two pressure seats are both arranged as arc-shaped structures and bonded with arc-shaped air cushions, a positioning groove is arranged on one side of the bottom of the pressure seat, and a sliding sleeve in the positioning groove is provided with a positioning rod rotatably mounted on the top of the support seat, two insertion holes are arranged on one side of the top of the support seat, a vertical pipe is fixedly mounted on the other side of the bottom of the pressure seat, and the bottom end of the vertical pipe extends into the corresponding insertion hole, a connecting rod is arranged in the vertical pipe, and the top end of the connecting rod extends to the top of the corresponding pressure seat and is fixedly mounted with a pull head; this patent can compress and fix patients with limbs of different thicknesses, thereby reducing the number of different fixation tools, which reduces the occupied space on the one hand and reduces the cost on the other.

[0004] The above patent has the following problems during actual use: the patient extends his limbs between the two arc-shaped air cushions, which makes the operation difficult for some patients whose limbs are not easy to move; and secondary injuries are inevitable to the patients in the process of moving their limbs. Summary of the invention

[0005] The present invention is intended to provide a medical external fixation sleeve for limb injuries, so as to solve the problem that the existing fixation devices may cause secondary injuries to the limbs during use.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a medical external fixation sleeve for limb trauma, comprising a sleeve body, a vertical groove is provided at the bottom of the sleeve body, a pressure block is slidably connected in the vertical groove, a first spring is provided between the pressure block and the vertical groove, and the bottom of the pressure block is arc-shaped; a side groove is provided on the sleeve body, a first material roller is rotatably connected in the side groove, a first torsion spring is provided between the first material roller and the side groove, and a carrying belt is wound around and fixedly connected to the first material roller; and also includes a pulling mechanism for pulling the carrying belt and a squeezing mechanism for squeezing the pressure block.

[0007] The principles and advantages of this solution are: in this solution, the limb is located between the pressing block and the carrying belt, and the carrying belt is pulled straight by a pulling mechanism, and the pressing block is driven downward by extrusion to resist the limb, that is, the limb is fixed by the pressing block and the carrying belt; compared with the existing technology, this solution can pass the carrying belt through the bottom of the limb, without the patient's injured limb having more movement, or even without the patient's injured limb having movement, thereby effectively avoiding secondary injury to the patient's injured limb.

[0008] Furthermore, the pulling mechanism includes a side block fixed to the sleeve body and a cylindrical block rotatably connected to the side block, and the side block and the side groove are respectively located on both sides of the sleeve body; the end of the carrying belt away from the first material roller is detachably connected to the cylindrical block; and it also includes a positioning part for positioning the cylindrical block.

[0010] Furthermore, the positioning part includes a gear fixed to the cylindrical block, a transverse groove provided on the side block, and a vertical plate fixed to the side block. A rack is slidably connected in the transverse groove, the rack is meshed with the gear, a first wedge block is provided on the rack, the first wedge block is transversely slidably connected to the vertical plate, and a limiting groove is provided on the side wall of the first wedge block; an auxiliary block is provided on the vertical plate, a second wedge block for being squeezed by the first wedge block is vertically slidably connected to the auxiliary block, a second spring is provided between the second wedge block and the vertical plate, and the second wedge block is slidably engaged with the limiting groove.

[0011] Through the above arrangement, the cylindrical block is rotated so that more carrying belts are wound around the cylindrical block, and the carrying belt drives the first material roller to rotate, so that more carrying belts are released, and the first torsion spring is deformed; during the rotation of the cylindrical block, the cylindrical block drives the gear to rotate synchronously, and the gear and rack are engaged to drive the rack to move to the left, and the rack drives the first wedge block to squeeze the second wedge block, so that the second wedge block moves downward, and the second spring is compressed; the first wedge block continues to move, so that the second wedge block is against the side wall of the first wedge block; the first wedge block continues to move again, so that the second wedge block is opposite to the limiting groove, and the second wedge block slides upward into the limiting groove under the action of the second spring, so as to realize the positioning of the first wedge block, and then the cylindrical block is positioned by the rack and the gear, that is, the positioning of the carrying belt is realized.

[0012] Furthermore, a gong is provided on the auxiliary block, and a striking block for striking the gong is provided on the second wedge block, and the striking block abuts against the gong.

[0013] Through the above arrangement, during the downward movement of the second wedge block, the second wedge block drives the impact block to move downward, so that the impact block is separated from the gong; during the upward movement of the second wedge block, the second wedge block drives the impact block to move upward, so that the impact block hits the gong to produce a sound, thereby reminding the medical staff of the positioning of the carrying belt, and the carrying belt is stretched straight and against the bottom of the limb; the information is transmitted to the medical staff through sound, so that the medical staff does not have to keep visual observation, and the medical staff can do other rescue work, thereby saving more precious time for treatment.

[0014] Furthermore, the extrusion mechanism includes an adjusting cylinder, a support plate fixed to the side wall of the sleeve, an inner chamber opened in the sleeve, and a second material roller rotatably connected to the side groove, and the adjusting cylinder is detachably connected to the cylindrical block; the support plate and the side block are arranged on the same side, and a through hole is provided on the support plate, and the adjusting cylinder can rotate in the through hole and move along the length direction of the cylindrical block; the inner chamber extends to both sides of the sleeve, and the inner chamber is connected to the side groove; a second torsion spring is provided between the second material roller and the side groove, and an extrusion belt is wrapped around and fixed to the second material roller, and the end of the extrusion belt away from the side groove passes through the side groove, is wrapped around the inner chamber and fixed to the adjusting cylinder; the length of the extrusion belt is greater than the length of the carrying belt, the vertical groove is connected to the inner chamber, and the extrusion belt is against the top of the vertical block.

[0015] Through the above arrangement, after the positioning of the carrying belt is completed, the adjusting cylinder is driven away from the cylindrical block, so that the two are separated; the adjusting cylinder is rotated, so that more extrusion belts are wound around the adjusting cylinder, and the extrusion belt drives the second material roller to rotate, so that more extrusion belts are released, and the second torsion spring is deformed; when the extrusion belt is pulled out, the adjusting cylinder is driven close to the cylindrical block, so that the two are connected, thereby realizing the positioning of the adjusting cylinder, and then realizing the positioning of the extrusion belt.

[0016] As more extrusion bands are wrapped around the adjusting cylinder, the extrusion bands gradually straighten, causing the extrusion band to squeeze the pressing block to move downward, and the first spring is compressed; the pressing block continues to move downward, causing the pressing block to abut against the limb, that is, the limb is fixed by the pressing block and the supporting band; and the bottom of the pressing block is arc-shaped, so that the bottom of the pressing block is in contact with the limb more fully, and the limiting effect is better.

[0017] Furthermore, a special-shaped groove is provided on the cylindrical block, and a special-shaped block is provided on the adjusting cylinder, and the special-shaped block is slidably matched with the special-shaped groove.

[0018] Through the above arrangement, when the adjusting cylinder moves away from the cylindrical block, the shaped block moves out of the shaped groove to separate the two; when the adjusting cylinder and the cylindrical block approach each other, the shaped block slides into the shaped groove to connect the two.

[0019] Furthermore, bottom grooves are provided on both sides of the bottom of the pressing block; wall grooves are provided on both sides of the side walls of the pressing block, the wall grooves are communicated with the vertical grooves and the bottom grooves, a wall block is slidably connected in the wall grooves, a clamping block is provided on the wall block, the clamping block is located in the bottom groove, and the clamping block can move horizontally and vertically in the bottom groove; inclined grooves are provided on both sides of the inner wall of the vertical groove, the spacing between the two inclined grooves gradually decreases from top to bottom, and the end of the wall block away from the clamping block is slidably connected to the inclined groove.

[0020] Through the above arrangement, during the downward movement of the pressing block, the pressing block drives the wall block to move along the path of the inclined groove, so that the wall block moves laterally along the path of the wall groove, that is, the two wall blocks are close to each other, and then the two clamping blocks are also close to each other; because the bottom of the two pressing blocks is arc-shaped, the bottom of the clamping block is lower than the bottom of the pressing block, and therefore, the two clamping blocks can be used to clamp the limb, further enhancing the fixation effect of the limb.

[0021] In addition, by adjusting the cylinder to individually control the amount of extrusion belt pulled out, the height of the downward movement of the pressing block can be adjusted, and the distance between the two clamping blocks will also be adaptively adjusted as the height of the pressing block descends, so that limbs of different sizes can be fixed, which is very practical.

[0022] Furthermore, an elastic layer is provided at the bottom of the pressing block.

[0023] Through the above arrangement, the elastic layer replaces the pressing block to directly contact the limbs, which makes the comfort stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The specific implementation process is as follows:

[0037] When in use, the sleeve 10 is placed on the wound on the patient's limb 80 so that the limb 80 is located below the pressing block 12; then the carrying belt 16 is pulled around the bottom of the limb 80 to connect the stab-surface Velcro with the velvet-surface Velcro, thereby achieving the connection between the carrying belt 16 and the cylindrical block 21. Therefore, at this time, the limb 80 is located in the space enclosed by the sleeve 10 and the carrying belt 16.

[0038] The cylindrical block 21 is rotated so that more carrying belts 16 are wound around the cylindrical block 21, and the carrying belt 16 drives the first material roller 15 to rotate, so that more carrying belts 16 are released, and the first torsion spring is deformed; during the rotation of the cylindrical block 21, the cylindrical block 21 drives the gear 30 to rotate synchronously, and the gear 30 is engaged with the rack 33 to drive the rack 33 to move leftward, and the rack 33 drives the first wedge block 34 to squeeze the second wedge block 37, so that the second wedge block 37 moves downward, and the second spring 38 is compressed; the first wedge block 34 continues to move, so that the second wedge block 37 is against the side wall of the first wedge block 34; the first wedge block 34 continues to move again, so that the second wedge block 37 is opposite to the limiting groove 35, and the second wedge block 37 slides upward into the limiting groove 35 under the action of the second spring 38, so as to realize the positioning of the first wedge block 34, and then the cylindrical block 21 is positioned by the rack 33 and the gear 30, that is, the positioning of the carrying belt 16 is realized, so that the carrying belt 16 is straightened and against the bottom of the limb 80.

[0039] During the downward movement of the second wedge block 37, the second wedge block 37 drives the impact block 41 to move downward, so that the impact block 41 is separated from the gong 40; during the upward movement of the second wedge block 37, the second wedge block 37 drives the impact block 41 to move upward, so that the impact block 41 hits the gong 40 to produce a sound, thereby reminding the medical staff of the positioning of the carrying belt 16, and the carrying belt 16 is stretched straight and against the bottom of the limb 80; the information is transmitted to the medical staff through sound, so that the medical staff does not have to keep visual observation, and the medical staff can do other rescue work, thereby saving more precious time for rescue.

[0040] During the rotation of the cylindrical block 21, the cylindrical block 21 drives the adjusting cylinder 50 to rotate synchronously, so that part of the extrusion belt 55 is wound around the adjusting cylinder 50, but because the length of the extrusion belt 55 is greater than the length of the carrier belt 16, the extrusion belt 55 is still not in a straightened state.

[0041] After completing the positioning of the carrying belt 16, the adjusting cylinder 50 is driven away from the cylindrical block 21, so that the special-shaped block 54 is moved out of the special-shaped groove; the adjusting cylinder 50 is rotated, so that more extrusion belts 55 are wound around the adjusting cylinder 50, and the extrusion belt 55 drives the second material roller 53 to rotate, so that more extrusion belts 55 are released, and the second torsion spring is deformed; when the extrusion belt 55 is pulled out, the adjusting cylinder 50 is driven close to the cylindrical block 21, so that the special-shaped block 54 slides into the special-shaped groove, thereby realizing the positioning of the adjusting cylinder 50, and then realizing the positioning of the extrusion belt 55.

[0042] As more extrusion bands 55 are wrapped around the adjustment cylinder 50, the extrusion bands 55 are gradually straightened, so that the extrusion bands 55 squeeze the pressing block 12 to move downward, and the first spring 13 is compressed; the pressing block 12 continues to move downward, so that the pressing block 12 and the limb 80 are abutted, that is, the limb 80 is fixed by the pressing block 12 and the supporting band 16; and the bottom of the pressing block 12 is arc-shaped, so that the bottom of the pressing block 12 is in contact with the limb 80 more completely, and the limiting effect is better.

[0043] During the downward movement of the pressing block 12, the pressing block 12 drives the wall block to move along the path of the inclined groove 63, so that the wall block moves laterally along the path of the wall groove 61, that is, the two wall blocks are close to each other, and then the two clamping blocks 62 are also close to each other, so that the two clamping blocks 62 are respectively against the limb 80, so that the two clamping blocks can be used to clamp the limb 80, further strengthening the fixing effect of the limb 80.

[0044] In addition, by adjusting the cylinder 50 to individually control the amount of extrusion belt 55 pulled out, the height of the downward movement of the pressing block 12 can be adjusted, and the distance between the two clamping blocks 62 can also be adaptively adjusted as the height of the pressing block 12 descends, thereby fixing limbs 80 of different sizes, which is highly practical.

[0045] In this embodiment, an elastic layer 70 is fixed to the bottom of the pressing block 12. The elastic layer 70 is a rubber layer and is arc-shaped. The elastic layer 70 directly contacts the limb 80 instead of the pressing block 12, which makes the feeling of comfort stronger.

[0046] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
