Existing medical arm fixing devices cannot simulate the swinging of the arm of the injured person, that is, they cannot facilitate the injured person to reduce the physical strength consumed by their own body movement in the case of a fractured arm, and thus cannot reduce the difficulty for the injured person to reach the hospital for treatment in areas with inconvenient transportation, thereby reducing the comfort of the injured person during movement in the process of use;

[0006] 2. Existing medical arm fixing devices are not easy to carry, that is, they cannot be carried when going out for use in case of emergency, and at the same time, they cannot reduce the weight borne by the injured person during use, and thus cannot reduce the physical strength consumption caused by this for the injured person after use, thereby bringing certain inconvenience to the use of the injured person;

[0007] 3. Existing medical arm fixing devices do not have the function of assisting in drug injection, that is, they cannot restrain the arm of the injured person when the injured person has excessive pain, and thus cannot assist others in drug injection by making the blood vessels of the injured person bulge, thereby bringing certain inconvenience to others in drug injection for the injured person;

[0008] 4. Existing medical arm fixing devices do not have the function of adjusting the restraint position according to specific situations, that is, they cannot reasonably fix the arm according to the specific fracture situation of the injured person, thereby increasing the probability of secondary injury to the injured person due to fixation;

[0009] 5. Existing medical arm fixing devices do not have an adjustment function, that is, they cannot be adjusted to be suitable according to the body shape and size of the injured person, and thus cannot improve the comfort of the injured person during the process of the injured person exercising with an injury, thereby bringing certain discomfort to the use of the injured person during exercise.

[0023] (III) Beneficial effects

[0024] The beneficial effects of the present invention are:

[0025] 1. The military-civilian dual-use medical arm fixation device is connected to the shoulders of the injured person through two shoulder clamps included in two fulcrum devices. Thus, the two connecting columns can use the shoulders of the injured person as a support. At the same time, through the bearings and the connecting seats, the two connecting columns can be rotated for use. Then, with the assistance of corresponding teammates, the injured person can use the first restraint belt and the first magic tape included in the power device to connect the follower plate to the intact arm of the injured person. Thus, the intact arm of the injured person is used as power. When the intact arm of the injured person swings, it will drive the corresponding connecting column to rotate. When the corresponding connecting column rotates, it will drive the transmission sleeve fixedly connected to the inner wall of the connecting column to rotate. When the transmission sleeve rotates, it will drive the mating disc to rotate. When the corresponding mating disc rotates, it will drive another mating disc to rotate through the mating column. When the other mating disc rotates, it will drive another transmission sleeve to drive another connecting column to rotate. When the other connecting column rotates, it will drive the extension column to rotate. When the extension column rotates, it will drive the driving gear to rotate. When the driving gear rotates, it will drive the reverse gear to rotate. During the rotation of the reverse gear, the linkage shaft will be used to drive the transmission arm to rotate. During the rotation of the transmission arm, it will be restricted by the positioning arc block and the positioning rail. Thus, the relative position of the transmission arm is maintained and the rotation stability of the transmission arm is maintained, that is, the stability during the operation of the structure is maintained. At the same time, the reverse gear and the driving gear are protected to a certain extent, that is, the operation stability of the structure during the use of the injured person in the wild is maintained. After the transmission arm rotates, it will drive the transmission pin to follow through the adaptation groove opened on the transmission arm. During the follow-up of the transmission pin, it will drive the linkage plate to swing in the opposite direction to the swing direction of the intact arm of the injured person. During the rotation of the linkage plate, it will drive the rotating head to rotate around the extension column as the center. After the rotating head rotates, it will swing synchronously with the linkage plate by using the second folding seat and the swing plate. Thus, it assists the injured person to exercise during the field training, and at the same time, it can also assist the injured person to walk stably during the injury recovery period. Thereby, it solves the problem that the existing medical arm fixation device cannot simulate the arm swing of the injured person, that is, it is not convenient for the injured person with a fractured arm to reduce the physical strength consumed by their own body movement, and thus cannot reduce the difficulty for the injured person to reach the hospital for treatment in places with inconvenient transportation, thereby reducing the problem of the movement comfort of the injured person during use.

[0026] 2. The military-civilian dual-purpose medical arm fixation device maintains the relative positions of the two connecting columns by means of a plurality of limiting rings evenly arranged on the outer side surface of the matching column and the clamping rings fixedly connected to the opposite surfaces of the two connecting columns, so as to facilitate the staff to use the follower plate included in the swinging device as a handle and the end of the connecting column facing the power device as a ground support point, that is, to form a snake-beating roller or an open-carrying crutch to assist the carrying personnel to walk in the wild or outdoors. During this process, the positioning device, the power device and the swinging device can be bound to the carrying device through the first restraint belt, the second restraint belt, the first magic tape and the second magic tape for folding to facilitate the use or carrying by the user, thus solving the problem that the existing medical arm fixation device is not convenient to carry, that is, it cannot be carried out when going out for use in case of emergency, and at the same time, it cannot reduce the weight borne by the injured person during the use process, and further cannot reduce the physical consumption caused by the injured person after use, thus bringing certain inconvenience to the use of the injured person.

[0027] 3. The military-civilian dual-purpose medical arm fixation device judges whether the injured person has a venous injury or an arterial injury by the color of the bleeding blood, and then uses a plurality of second restraint belts or third restraint belts to tighten the distal end or the proximal end of the bleeding position, thereby improving the hemostasis speed of the injured person. And when drug injection is required, the tightening of the injured arm of the injured person can also be tightened, thereby assisting the corresponding drug injection personnel to show the blood vessels of the injured person, that is, assisting the corresponding personnel to carry out drug injection, thus solving the problem that the existing medical arm fixation device does not have the function of assisting in drug injection, that is, it cannot bind the arm of the injured person when the injured person has excessive pain, and then bulge the blood vessels of the injured person to assist others in injecting drugs into the injured person, thus bringing certain inconvenience to the drug injection of the injured person by others.

[0028] 4. The military-civilian dual-use medical arm fixation device rotates with the corresponding connecting column as the fulcrum through the auxiliary ring plate. At the same time, the relative position of the positioning plate is positioned by the third folding seat. After the relative position of the positioning plate is positioned, the positioning plate can be connected to the position near the shoulder of the fractured arm of the injured person through a plurality of corresponding second restraint belts and the corresponding second magic tape. Subsequently, a teammate or others can be instructed to rotate the wing nut, and then loosen the clamping of the fastening disc and the wing nut on the positioning connecting frame. Then, the positioning connecting frame can be pulled to move. During the movement of the positioning connecting frame, the fastening stud will be driven to move in the adjusting long groove. After that, the third restraint belt and the corresponding second magic tape can be used to connect to the palm end of the injured arm of the injured person. Next, the wing nut can be rotated, and then the fastening disc and the wing nut are coordinated to clamp the positioning connecting frame to fix the height position and angle of the positioning connecting frame, thereby fixing the injured arm of the injured person, reducing the probability of secondary injury caused by shaking during the movement of the injured person, and the positioning connecting frame is connected to the palm end of the injured arm of the injured person, and the positioning plate is connected to the shoulder end of the injured arm of the injured person, so as to adapt to the fracture between the two ends of the injured arm of the injured person, reduce the harm to the injured person when fixing the injured arm of the injured person, and thus solve the problem that the existing medical arm fixation device does not have the function of adjusting the restraint position according to specific conditions, that is, it cannot perform reasonable arm fixation according to the specific fracture condition of the injured person, thereby increasing the probability of secondary injury of the injured person due to fixation.

[0029] 5. The military-civilian dual-use medical arm fixation device is restricted and guided through the cooperation column. During the process of the cooperation column for restricted guidance, it will be assisted and restricted by two blocking discs, and through the telescopic holes opened in both connecting columns, the cooperation of the transmission sleeve fixedly connected in the telescopic hole and the cooperation disc for cooperation and restricted guidance, so as to maintain the stability of the relative movement of the two connecting columns. Moreover, the stability of the structure will also be maintained through the cooperation of the cooperation disc and the blocking disc. During the process of the two connecting columns moving away from each other stably, the relative position after expanding the two connecting columns to an appropriate distance will also be maintained through a plurality of limiting rings uniformly arranged on the outer side surface of the cooperation column and the clamping rings fixedly connected to the opposite surfaces of the two connecting columns, thereby solving the problem that the existing medical arm fixation device does not have an adjustment function, that is, it cannot be adjusted and adapted according to the body size of the injured person, and thus cannot improve the comfort of the injured person during the movement of the injured person with injuries, thereby bringing certain discomfort to the use of the injured person during the movement process.

Detailed implementation manner

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Such as Figure 1-17As shown, the present invention provides a technical solution: a dual-purpose medical arm fixing device for military and civilian use, including a backpack 2, which can cooperate with a fulcrum device 3 to allow a user to use his or her own shoulder as a support point to rotate the backpack 2, thereby achieving the purpose of transmitting power. One end of the backpack 2 is fixedly connected to the power device 1, and fulcrum devices 3 are provided on both sides of the center of the backpack 2. The fulcrum device 3 can increase the comfort of the user, thereby maintaining the transmission of the backpack 2 and limiting the functionality of the positioning device 5. Further, the other end of the backpack 2 is provided with a positioning device 5 and a swinging device 4 in sequence along the length direction from the center of the backpack 2 to the end. The positioning device 5 is provided to fix the arm of the injured person. The swing device 4 is configured to simulate the arm swinging of the injured person during exercise, thereby assisting the injured person in training or walking to a certain extent, that is, reducing the body imbalance caused by the injured person being unable to swing his arm during training or walking, thereby reducing the physical consumption of the injured person during training or walking to a certain extent. A weighting device 6 is fixed on the side of the swing device 4 away from the center of the carrying device 2. The weighting device 6 can enable the injured person to control the swing weight of the swing device 4 using local materials, thereby improving the similarity of the simulated arm swinging to a certain extent, thereby further reducing the physical consumption of the injured person during training or walking.

[0050] The carrying device 2 includes two connecting posts 21, and telescopic holes 24 are provided in the two connecting posts 21 to adapt to the different body shapes of different users, thereby improving the universality of the carrying device 2, and different lengths can be adjusted to adapt to the use of people of different body shapes as a crutch. The inner walls of the two telescopic holes 24 are fixedly connected with transmission sleeves 22, and the two connecting posts 21 are fixedly connected with blocking plates 28 at the corresponding telescopic holes 24. The two transmission sleeves 22 are both spline-shaped, and the two transmission sleeves 22 are connected with matching plates 23, so that the synchronous rotation function of the two connecting posts 21 can be maintained while adjusting the distance between the two connecting posts 21, thereby realizing The power transmission of the swing arm and the simulation of the swing arm are shown. The opposite surfaces of the two matching disks 23 are fixedly connected with the two ends of the matching column 26. A plurality of limiting rings 25 are evenly distributed on the matching column 26. The limiting rings 25 are clamped with a clamping ring 27. Two clamping rings 27 are provided and are fixedly connected to the opposite surfaces of the two connecting columns 21 respectively. The setting of the limiting rings 25 and the clamping rings 27 can limit the positioning of the two connecting columns 21 after the spacing is adjusted. The end of any one of the two connecting columns 21 is fixedly connected with an extension column 29, so that the swing device 4 is staggered with the injured arm of the injured person, thereby reducing the probability of the swing device 4 colliding with the injured arm of the injured person.

[0051] A swing device 4 is rotatably connected to the lengthened column 29. The swing device 4 includes a rotating head 41. A second folding seat 43 is fixedly connected to the vertically downward end of the rotating head 41. The second folding seat 43 is rotatably connected to a swing plate 42, thereby realizing the folding of the swing plate 42. At the same time, it is positioned on the connecting column 21 by means of the cooperation of the second restraint belt 55 to complete the folding. A weight device 6 is fixedly connected to the side of the swing plate 42 facing away from the connecting column 21. One end of the rotating head 41 facing away from the second folding seat 43 is fixedly connected to a linkage plate 410. A transmission nail 49 is fixedly connected to the end of the linkage plate 410. The power transmitted by the cooperation of the linkage plate 410 and the transmission nail 49 can make the rotating head 41 swing, and then cooperate with the swing plate 42 to achieve the effect of simulating the arm. The transmission nail 49 is connected to a transmission arm 47. One end of the transmission arm 47 facing away from the transmission nail 49 is fixedly connected to a linkage shaft 412. One end of the linkage shaft 412 facing the connecting column 21 is fixedly connected to a reverse gear 411. The reverse gear 411 is drivingly connected to a driving gear 44. The settings of the driving gear 44 and the reverse gear 411 are to cooperate with the swing of the intact arm of the injured person to make the swing plate 42 swing in the reverse direction, thereby realizing the simulation of the arm swing, that is, reducing the body imbalance caused by the inability of the arm to swing during the training or walking of the injured person, and thus reducing the physical consumption of the injured person to a certain extent during the training or walking process. The driving gear 44 is fixedly connected to the lengthened column 29.

[0052] One end of the transmission arm 47 facing the lengthened column 29 is fixedly connected to a positioning arc block 413. One end of the transmission arm 47 facing the linkage shaft 412 is circular, so that the positioning arc block 413 cooperates with the positioning rail 46 to perform limit positioning when the transmission arm 47 is rotatable. The positioning arc block 413 is slidably connected in the positioning rail 46. The settings of the positioning arc block 413 and the positioning rail 46 can maintain the connection between the lengthened column 29 and the transmission arm 47, and at the same time can also maintain the transmission function of the transmission arm 47 and its relative position. The positioning rail 46 is fixedly connected to a positioning block 45. The positioning block 45 is fixedly connected to the outer peripheral surface of the lengthened column 29. An adaptation groove 48 is formed in the transmission arm 47. The setting of the adaptation groove 48 can prevent the situation of structural interference between the transmission nail 49 and the transmission arm 47 due to the change of the position of the transmission nail 49. The adaptation groove 48 is connected to the transmission nail 49.

[0053] The fulcrum device 3 includes a connecting seat 32, the outer peripheral surface of the bearing 33 is fixedly connected to the connecting seat 32, and the inner side surface of the bearing 33 is fixedly connected to the connecting column 21, thereby maintaining the rotational connection function between the connecting seat 32 and the connecting column 21, that is, maintaining the rotational transmission function of the connecting column 21, thereby realizing the simulation of the swing arm, the connecting seat 32 is arranged on the outer peripheral surface of the connecting column 21 at one end facing the center of the matching column 26, and the connecting seat 32 is fixedly connected to the shoulder clamp 31, thereby positioning the connecting seat 32 at the shoulder position of the injured person, thereby maintaining the rotational stability of the connecting column 21, and the shoulder clamp 31 is U-shaped and made of rubber, thereby maintaining the stability of the connecting seat 32 positioned at the shoulder of the injured person and improving the comfort of the injured person.

[0054] The power device 1 includes a follower plate 13, which is rotatably connected to a first folding seat 14. The first folding seat 14 is fixedly connected to a transmission block 15, so that the follower plate 13 can be folded. The transmission block 15 is fixedly connected to the outer peripheral surface of the end of the connecting column 21 away from the center of the matching column 26. Two first restraints 11 are fixedly connected to the follower plate 13. The two first restraints 11 are connected by two first Velcro strips 12, so as to achieve the purpose of connecting the arms of the injured person, that is, the intact arm of the injured person is used as power to simulate the swing of the other arm of the injured person. At the same time, the folded follower plate 13 can also be restrained to the connecting column 21 to complete the folding, so as to facilitate the user to carry, and the two first restraints 11 are both made of elastic material.

[0055] The side of the follower plate 13 away from the connecting column 21 exceeds the shoulder by 15 cm, thereby preventing the follower plate 13 from affecting the swinging movement of the intact arm of the injured person, and also forming a structure similar to a shoulder armor to protect the intact arm of the injured person.

[0056] The weight increasing device 6 includes a bearing box 61 which is fixedly connected to the swing plate 42. A filling pipe 66 is fixedly communicated with the side wall of the bearing box 61. A closing plug 62 is clamped at the end of the filling pipe 66 away from the bearing box 61, thereby realizing the closing of the bearing box 61. After the filling pipe 66 is separated from the closing plug 62, corresponding granular impurities such as water or gravel can be injected into the bearing box 61, thereby increasing the weight of the bearing box 61. Threaded holes are formed in the lower side surface of the bearing box 61, and a sealing screw 65 is threadedly connected in the threaded holes. A sealing gasket 63 is fixed on the side surface of the sealing screw 65 facing the bearing box 61. The sealing gasket 63 is provided to maintain the sealing performance of the sealing screw 65 for sealing the bearing box 61. When the sealing screw 65 is separated from the threaded hole formed at the bottom of the bearing box 61, the sealing gasket 63 is separated from the threaded hole. Then, the corresponding heavy objects can be discharged from the inside of the bearing box 61, thereby reducing the weight of the bearing box 61. A rotating plate 64 is fixedly connected to the lower side surface of the sealing screw 65. The cross section of the rotating plate 64 is trapezoidal with a narrow upper part and a wide lower part, which is convenient for the injured person to hold and rotate the sealing screw 65, so as to realize the adjustment of the weight of the bearing box 61.

[0057] The positioning device 5 includes an auxiliary ring plate 51. A third folding seat 52 is fixedly connected to the auxiliary ring plate 51. The third folding seat 52 is rotatably connected to a positioning plate 53, thereby realizing the rotation and folding of the positioning plate 53. That is, the positioning plate 53 and the swing plate 42 are symmetrically arranged on both sides of the connecting column 21. Then, the swing plate 42 and the positioning plate 53 can be bound to the connecting column 21 by using the second restraint belt 55 for the user to hold and transfer. A second restraint belt 55 is fixedly connected to the positioning plate 53. The second restraint belt 55 is connected through a corresponding second magic tape 57, thereby connecting the injured arm of the injured person to fix it and reducing the probability of secondary injury. An adjusting long groove 511 is formed in the positioning plate 53. A fastening stud 510 is slidably connected in the adjusting long groove 511. Both ends of the fastening stud 510 are rotatably connected to the same positioning connecting frame 59. The optical axis end of the fastening stud 510 passes through the positioning connecting frame 59 and is fixedly connected to a fastening disc 56. The threaded end of the fastening stud 510 passes through the positioning connecting frame 59 and is threadedly connected to a wing nut 54, thereby realizing the adjustment of various angles and extension lengths of the positioning connecting frame 59. Then, the positioning connecting frame 59 can be connected to the palm end of the injured arm of the injured person, and the positioning plate 53 is connected to the shoulder end of the injured arm of the injured person, so as to adapt to the fracture between both ends of the injured arm of the injured person, reduce the injury to the injured person when fixing the injured arm of the injured person, and at the same time, others can inject drugs on the exposed skin that is not bound and positioned. At the same time, a good ventilation effect can be maintained, thereby improving the comfort of the injured person. The wing nut 54 is convenient for the staff to rotate for positioning the positioning connecting frame 59. A third restraint belt 58 is fixedly connected to the end of the positioning connecting frame 59 away from the positioning plate 53. The third restraint belt 58 is connected through another second magic tape 57.

[0058] A plurality of second restraint bands 55 are provided and are all fixedly connected to the positioning plate 53, thereby facilitating the injured person to connect different amounts of second restraint bands 55 according to their own situation, that is, to achieve the connection stability between the positioning plate 53 and the injured arm. At the same time, it can also be used as a tightening rubber band for hemostasis or assisting in showing blood vessels for drug injection. The positioning connecting frame 59 is a concave frame, thereby maintaining the stability of positioning the injured person. The auxiliary ring plate 51 is rotatably connected to the connecting column 21, thereby maintaining the stability of the simulated arm swing.

[0059] The operation steps of the present invention are as follows:

[0060] When corresponding personnel need to carry out field training, the power device 1, the carrying device 2, the swinging device 4, the positioning device 5, the fulcrum device 3 and the weighting device 6 can be placed in the backpack. Subsequently, the corresponding personnel can conveniently carry them for field training. Moreover, the relative positions of the two connecting columns 21 can be maintained by a plurality of limiting rings 25 uniformly arranged on the outer side surface of the matching column 26 and the clamping rings 27 fixedly connected to the opposite surfaces of the two connecting columns 21. Thus, it is convenient for the staff to use the follower plate 13 included in the swinging device 4 as a handle and the end of the connecting column 21 facing the power device 1 as a ground support point, that is, to form a snake-beating roller or an opening crutch to assist the carrying personnel to walk in the wild. When in need of use, the positioning device 5 can be rotated and the positioning device 5, the power device 1 and the swinging device 4 can be unfolded. During the process of unfolding the positioning device 5, the power device 1 and the swinging device 4, connection restrictions can be carried out through the first folding seat 14, the second folding seat 43 and the third folding seat 52. After use, the positioning device 5, the power device 1 and the swinging device 4 can be bound to the carrying device 2 through the first restraint band 11, the second restraint band 55, the first magic tape 12 and the second magic tape 57 for folding to facilitate the carrying and use by the user;

[0061] When a situation of arm fracture occurs during training, first, pull the two connecting columns 21 included in the carrying device 2 according to the build of the injured person, so as to make the two connecting columns 21 move away from each other. During the process of the two connecting columns 21 moving away from each other, the cooperation column 26 will be used for limiting and guiding. During the process of the cooperation column 26 for limiting and guiding, the two blocking disks 28 will be used for assisting in limiting and guiding. And through the telescopic holes 24 opened in both of the two connecting columns 21, the transmission sleeves 22 fixedly connected in the telescopic holes 24 and the cooperation of the cooperation disks 23, the cooperation and limiting guidance are carried out, so as to maintain the stability of the relative movement of the two connecting columns 21. Moreover, the stability of the structure will also be maintained through the cooperation of the cooperation disk 23 and the blocking disk 28. During the process of the two connecting columns 21 stably moving away from each other, the relative positions after the two connecting columns 21 are unfolded to an appropriate distance will also be maintained through a plurality of limiting rings 25 uniformly arranged on the outer side surface of the cooperation column 26 and the clamping rings 27 fixedly connected to the opposite surfaces of the two connecting columns 21. After use, the above operations can be reversed, and at the same time, positioning will also be carried out through the cooperation of the plurality of limiting rings 25 and the clamping rings 27, so as to further improve the functionality of facilitating the carrying of the carried person;

[0062] When the staff adjusts the distance between the opposite ends of the two connecting columns 21 to be appropriate, that is, to adapt to the use by the injured person, the two shoulder clamps 31 included in the two fulcrum devices 3 can be connected to the shoulders of the injured person. Thus, the two connecting columns 21 can use the shoulders of the injured person as a support. At the same time, through the bearing 33 and the connecting seat 32, the two connecting columns 21 can be rotated for use. Then, with the assistance of corresponding teammates, the injured person can use the first restraint strap 11 and the first magic tape 12 included in the power device 1 to connect the follower plate 13 to the intact arm of the injured person. Thus, the intact arm of the injured person is used as power. When the intact arm of the injured person swings, it will drive the corresponding connecting column 21 to rotate. When the corresponding connecting column 21 rotates, it will drive the transmission sleeve 22 fixedly connected to the inner wall of the connecting column 21 to rotate. When the transmission sleeve 22 rotates, it will drive the mating disk 23 to rotate. When the corresponding mating disk 23 rotates, it will drive another mating disk 23 to rotate through the mating column 26. When the other mating disk 23 rotates, it will drive another transmission sleeve 22 to drive another connecting column 21 to rotate. When the other connecting column 21 rotates, it will drive the extension column 29 to rotate. When the extension column 29 rotates, it will drive the driving gear 44 to rotate. When the driving gear 44 rotates, it will drive the reverse gear 411 to rotate. During the rotation of the reverse gear 411, it will drive the transmission arm 47 to rotate through the linkage shaft 412. During the rotation of the transmission arm 47, it will be restricted by the positioning arc block 413 and the positioning rail 46. Thus, the relative position of the transmission arm 47 is maintained and the rotation stability of the transmission arm 47 is maintained, that is, the stability during the operation of the structure is maintained. At the same time, the reverse gear 411 and the driving gear 44 are protected to a certain extent, that is, the operation stability of the structure during the use of the injured person in the wild is maintained. After the transmission arm 47 rotates, it will drive the transmission pin 49 to follow through the adaptation groove 48 opened on the transmission arm 47. During the follow-up of the transmission pin 49, it will drive the linkage plate 410 to swing in the opposite direction to the swinging direction of the intact arm of the injured person. During the rotation of the linkage plate 410, it will drive the rotating head 41 to rotate with the extension column 29 as the center. After the rotating head 41 rotates, it will swing synchronously with the linkage plate 410 by using the second folding seat 43 and the swinging plate 42. Thus, it assists the injured person to exercise during the field training, and at the same time, it can also assist the injured person to walk stably during the injury recovery period. Thereby, the physical consumption of the injured person during movement, walking or running is reduced, and at the same time, the walking stability of the injured person is improved;

[0063] In the process of utilizing the swing plate 42 to swing and assist the injured person in stable movement with low physical exertion, the closing plug 62 can be pulled to separate from the injection tube 66. After the injection tube 66 is separated from the closing plug 62, the corresponding granular impurities such as water or gravel can be injected into the carrying box 61, thereby increasing the weight of the carrying box 61. At the same time, the sealing screw 65 can be rotated by the rotating plate 64 to separate from the threaded hole opened at the bottom of the carrying box 61, thereby separating the sealing gasket 63 from the threaded hole, and then the corresponding heavy objects can be discharged from the inside of the carrying box 61, thereby reducing the weight of the carrying box 61, thereby achieving the purpose of controlling the weight of the carrying box 61, that is, reducing the weight of the weighting device 6 on the premise of improving the effect of the swing plate 42 swinging to correct the body tilt of the injured person, that is, reducing the physical exertion of the injured person caused by excessive weight;

[0064] When the injured person's arm is fractured, the auxiliary ring plate 51 will rotate with the corresponding connecting column 21 as the fulcrum, and at the same time, the relative position of the positioning plate 53 will be positioned through the third folding seat 52. After the relative position of the positioning plate 53 is positioned, the positioning plate 53 can be connected to the position of the injured person's fractured arm near the shoulder through multiple corresponding second restraints 55 and corresponding second Velcro 57. Then, the teammates or others can rotate the wing nut 54, and then the clamping of the fastening plate 56 and the wing nut 54 on the positioning frame 59 can be loosened, and then the positioning frame 59 can be pulled to move. During the movement of the positioning frame 59, the fastening stud 510 will be driven to move in the adjustment slot 511, and then The third restraint belt 58 and the corresponding second Velcro 57 can be used to connect the palm end of the injured person's injured arm, and then the wing nut 54 can be rotated, and then the fastening plate 56 and the wing nut 54 can be used in conjunction with the fastening stud 510 to clamp the positioning frame 59 to fix the height position and angle of the positioning frame 59, thereby fixing the injured person's injured arm to reduce the probability of secondary injury caused by shaking during the injured person's movement. The positioning frame 59 is connected to the palm end of the injured person's injured arm, and the positioning plate 53 is connected to the shoulder end of the injured person's injured arm, so as to adapt to the fracture between the two ends of the injured person's injured arm and reduce the damage to the injured person when fixing the injured person's injured arm;

[0065] When the injured person's arm is fractured and bleeding occurs, it can be determined whether the injured person has a venous injury or an arterial injury based on the color of the bleeding blood. Then, multiple second restraints 55 or third restraints 58 are used to tighten the distal end or the inlet end of the bleeding position, thereby increasing the speed of hemostasis for the injured person. When drug injection is required, the injured person's injured arm can be tightened, thereby assisting the corresponding drug injection personnel to show the injured person's blood vessels, thereby assisting the corresponding personnel in drug injection.

It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
