Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an associated matching fixation device for orthopedic upper limb fractures. Background Art

[0002] The upper limbs include the shoulder, upper arm, elbow, forearm, wrist and hand. Among them, most fracture patients suffer from arm injuries. After an arm fracture occurs, surgical treatment is generally performed first, and then fixation devices such as plaster, splints or braces are used to fix the fracture site to facilitate the patient's healing.

[0003] A Chinese patent with application number 201810976900.8 discloses an arm fixation device for patients with arm fractures, including a first arc-shaped card plate, a second arc-shaped card plate, a cushion, a rubber card rod, a connecting block, a belt, a soft strip, a first sponge strip, a Velcro buckle, etc.; the front right portion of the first arc-shaped card plate is hingedly connected to the second arc-shaped card plate, and the second arc-shaped card plate and the inner upper and inner lower portions of the first arc-shaped card plate are all connected to cushions. The present invention can prevent the arm of a patient with an arm fracture from being hurt by the first arc-shaped card plate and the second arc-shaped card plate through the cushion; the first arc-shaped card plate and the second arc-shaped card plate can fix the arm of the patient with an arm fracture to prevent the arm swinging from affecting the wound, and can also achieve the effect of applying medicine to the suture without opening the fixing device; However, when the above technical scheme is in use, since the position of the sponge block is fixed, the sponge block can only be used to apply medicine to local wounds or surgical sutures on the arm. When the wound or surgical suture on the arm is long, it is impossible to apply medicine to the entire wound, which has certain limitations in use. In addition, when the above scheme applies medicine through the sponge block, the sponge block needs to absorb enough medicine. Since there is no mechanism to remove excess medicine on the sponge block, after applying the medicine, since the patient's arm is mostly in a vertical position to the ground, the excess medicine absorbed by the sponge block will drip from the bracket formed by the first arc-shaped pallet and the second arc-shaped pallet to the ground under the influence of gravity, thereby causing waste of medicine and affecting the environment.

The medicine delivery component 22 includes a rubber plate 221, a connecting tube 222 and an inner cavity 223. The rubber plate 221 is fixedly connected to the connecting rod 211, and the rubber plate 221 is distributed on the inner side of the inner cavity 223. The inner cavity 223 is opened on the inner side of the shell 1, and the outer side of the inner cavity 223 is fixedly connected with a feed port 224 and an exhaust port. Both the feed port 224 and the exhaust port are connected to the inner cavity 223. The outer side of the feed port 224 is threadedly connected with a protective cap 225, and the inner side of the connecting tube 222 is fixedly connected with a ring plate 2221, a compression spring 2222 is fixedly connected to the circumference of the ring plate 2221, and a sliding rod 2223 is fixedly connected to the end of the compression spring 2222 away from the ring plate 2221, and one end of the sliding rod 2223 passes through the ring plate 2221 and is fixedly connected to a sealing plug 2224, and a spring capillary 2225 is fixedly connected to the outer side of the connecting tube 222, and the end of the spring capillary 2225 away from the connecting tube 222 is connected to the sponge block 23, and a fixed shell 235 is fixedly connected to the outer side of the sponge block 23, and a slider 231 is arranged on the fixed shell 235, and a round-headed protruding rod 232 and a limit spring 233 are fixedly connected to the outer side of the slider 231, and the end of the round-headed protruding rod 232 away from the slider 231 is distributed on the inner side of the inner cavity 223, and the outer side of the round-headed protruding rod 232 is slidably connected to The storage groove 234 is arranged inside the inner cavity 223. When the driving component 21 drives the sponge block 23 to fit the wound, the round-headed protruding rod 232 can move into the storage groove 234. The moving component 24 includes a limiting frame 241 and a moving plate 242. The limiting frame 241 and the moving plate 242 are both fixedly connected to the outside of the fixed shell 235. One end of the spring capillary 2225 away from the connecting tube 222 is fixedly connected to the fixed shell 235. The slider 231 is slidably connected to the limiting frame 241. A fixed spring 243 is fixedly connected to the inner side of the limiting frame 241. One end of the fixed spring 243 away from the limiting frame 241 is fixedly connected to the slider 231. The outer side of the moving plate 242 is slidably connected to the limiting hole 244. The limiting hole 244 is arranged inside the shell 1.One end of the movable plate 242 away from the sponge block 23 passes through the limiting hole 244 and is distributed on the inner side of the housing 1. When the pressing plate 219 moves, it can drive the movable plate 242 to move downward along the limiting hole 244; In the initial state, the return spring 218 will squeeze the pressure plate 219. At this time, the trapezoidal block 212 is on the inner top surface of the shell 1. At this time, the shell 1 squeezes the pressure block 214, so that the pressure block 214 is on the inner side of the trapezoidal block 212. At the same time, the connecting spring 213 is also in a compressed state. When it is necessary to apply medicine, the feed port 224 is opened, and then the medicine is pushed into the inner cavity 223 through the syringe. Then, the feed port 224 is closed by the protective cap 225, and then the handle at the outer end of the connecting rod 211 is pulled. The movement of the handle drives the connecting rod 211 to move. The movement of the connecting rod 211 drives the pressure plate 219, the trapezoidal block 212 and the rubber plate 221 to move. The movement of the rubber plate 221 will move the inner cavity 22 3 is squeezed, and the medicine in the inner cavity 223 is squeezed to flow into the connecting tube 222 and squeeze the sealing plug 2224 on the ring plate 2221. At this time, the sealing plug 2224 is squeezed by the rubber plate 221 and is forced to move to the side away from the sliding rod 2223. The movement of the sealing plug 2224 drives the movement of the sliding rod 2223, and the movement of the sliding rod 2223 squeezes the compression spring 2222. With the movement of the sealing plug 2224, the connecting tube 222 is opened. At this time, the medicine in the inner cavity 223 passes through the gap between the sealing plug 2224 and the ring plate 2221 and enters the spring capillary 2225, and then enters the sponge block 23. At this time, the sponge block 23 absorbs the medicine, thereby realizing the transportation of the medicine. When the trapezoidal block 212 moves, the trapezoidal block 212 will contact the round-headed protruding rod 232 in the inner cavity 223, and as the trapezoidal block 212 moves, the trapezoidal block 212 squeezes the round-headed protruding rod 232, and at this time the round-headed protruding rod 232 moves toward the sponge block 23, and the movement of the round-headed protruding rod 232 drives the slider 231 to move, and the movement of the slider 231 drives the limit frame 241 to move and stretch the limit spring 233, and the movement of the limit frame 241 drives the fixed shell 235 to move, and the movement of the fixed shell 235 drives the sponge block 23 to move, and at this time the sponge block 23 is pushed to fit the wound, and as the trapezoidal block 212 moves, the connecting spring 213 in the trapezoidal block 212 is gradually released, and the sponge block 23 is pushed to fit the wound ... In the initial stage of movement of the trapezoidal block 212, the connecting spring 213 drives the pressing block 214 to keep in contact with the inner wall of the shell 1. As the trapezoidal block 212 moves, the connecting spring 213 is completely released. At this time, the pressing block 214 will move out of the trapezoidal block 212, and with the cooperation of the limiting rod 217, the pressing block 214 will move with the trapezoidal block 212. When the trapezoidal block 212 is separated from the round-headed protruding rod 232, the pressing block 214 will replace the trapezoidal block 212 and squeeze the round-headed protruding rod 232 again, thereby ensuring that the sponge block 23 can always fit the wound. In addition, since the wall thickness of the trapezoidal block 212 is relatively thin, when the pressing block 214 squeezes the round-headed protruding rod 232, the sponge block 23 will not retract significantly. The movement of the pressure plate 219 will squeeze the return spring 218, and as the connecting rod 211 continues to move out of the shell 1, the pressure plate 219 will contact the movable plate 242. At this time, as the connecting rod 211 moves, the pressure plate 219 will drive the movable plate 242 to move along the limiting hole 244. The movement of the movable plate 242 drives the fixed shell 235 to move along the limiting frame 241. The movement of the fixed shell 235 drives the sponge block 23 to move. At this time, the sponge block 23 is used to apply medicine to a longer wound. After the medicine application is completed, the handle is released. At this time, under the action of the return spring 218, the limiting spring 233 and the fixing spring 243, the connecting rod 211, the round-headed protruding rod 232 and the fixed shell 235 all return to their initial positions.

[0024] It should be noted that the elastic force of the return spring 218 is greater than the elastic force of the connecting spring 213 .

[0025] Example 4: See Figure 1-Figure 8 , which is different from the above-mentioned third embodiment, the pushing assembly 32 includes a mounting frame 321, a push rod 323 and a feeding port 322, the squeezing roller 31 is mounted on the inner side of the mounting frame 321, the mounting frame 321 is distributed on the inner side of the shell 1, the top end of the push rod 323 passes through the shell 1 and is fixedly connected to the mounting frame 321, a return spring 325 is fixedly connected to the push rod 323, and an end of the return spring 325 away from the push rod 323 is fixedly connected to an inner groove 324, and the inner groove 324 is provided on the rotating card plate 41; After the medicine is applied, the position of the sponge block 23 is kept unchanged, and the push rod 323 is pushed. The push rod 323 moves to drive the mounting frame 321 to move toward the sponge block 23. The mounting frame 321 moves to drive the squeezing roller 31 to move. The squeezing roller 31 moves to contact the sponge block 23 and squeeze the sponge block 23, thereby squeezing out the excess medicine absorbed by the sponge block 23, and the extruded medicine will be discharged through the discharge port 322, thereby avoiding the problem of the sponge block 23 absorbing too much medicine and causing dripping, and the medicine can also be recovered at the same time.

[0026] In actual use, the feed port 322 is connected to an external medicine recovery tank, so as to recover the excess medicine squeezed out by the squeezing roller 31 .
