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;

[0004] 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. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an associated fixing device for orthopedic upper limb fractures, which has the advantages of being able to fully apply medicine to longer wounds and squeeze out excess medicine absorbed by the sponge block, thereby solving the above-mentioned problems.

[0019] Compared with the prior art, the present invention provides an associated cooperation fixing device for orthopedic upper limb fractures, and has the following beneficial effects:

[0020] 1. In the present invention, when applying medicine, the driving component drives the medicine delivery component to deliver the medicine to the sponge block. While the driving component drives the medicine delivery component to operate, it drives the sponge block to move towards the wound until it fits the wound. Then, with the continuous operation of the driving component, the moving component operates. At this time, the moving component drives the sponge block to move along the wound, so as to realize applying medicine to the wound while greatly improving the range of medicine application, and further apply medicine to patients with strip-shaped and long wounds.

[0021] 2. After applying the medicine to the wound, the present invention drives the extrusion roller to squeeze the sponge block through the operation of the pushing component, so as to squeeze out the excess liquid medicine absorbed by the sponge block. The squeezed-out medicine flows out through the blanking port, so that while cleaning the sponge block, the medicine can also be collected, avoiding the problem that when the patient's arm is in a hanging state, after the sponge block absorbs more medicine, under the action of gravity, the excess medicine on the sponge block will drip onto the sponge pad in the bracket. Once the sponge pad in the bracket is saturated, the medicine will drip from the bracket, resulting in waste of medicine and affecting the environment at the same time;

[0022] 3. With the setting of the fixing mechanism in the present invention, it is convenient for the user to fix the bracket on the torso, thereby fixing the position of the bracket and avoiding the problem that the bracket is easily detached from the patient's arm during subsequent use.

[0032] 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.

[0033] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an associated cooperation fixing device for upper limb fractures in orthopedics.

[0034] Embodiment 1: Please refer to Figures 1-8 , an associated cooperation fixing device for upper limb fractures in orthopedics, including a housing 1, and a medicine application mechanism 2 and an extrusion mechanism 3 are arranged inside the housing 1;

[0035] The medicine application mechanism 2 includes a driving component 21, a medicine delivery component 22, a sponge block 23 and a moving component 24. The sponge blocks 23 are distributed inside the housing 1. When the driving component 21 operates, it drives the medicine delivery component 22 to deliver medicine to the sponge blocks 23, and drives the sponge blocks 23 to fit against the arm wound. When the moving component 24 operates, it drives the sponge blocks 23 to move along the wound;

[0036] The extrusion mechanism 3 includes an extrusion roller 31 and a pushing component 32. The extrusion rollers 31 are distributed inside the housing 1, and the extrusion rollers 31 are used to press dry the excess medicine on the sponge blocks 23. When the pushing component 32 operates, it drives the extrusion rollers 31 to move along the surface of the sponge blocks 23;

[0037] A fixing mechanism 5 is also arranged on the outer side of the housing 1, and the fixing mechanism 5 is used to fix the housing 1 on the upper limb of the patient.

[0038] During use, the driving assembly 21 operates. The operation of the driving assembly 21 drives the medicine delivery assembly 22 to operate. The medicine delivery assembly 22 transports the medicine to the sponge block 23 during operation. While the driving assembly 21 drives the medicine delivery assembly 22 to operate, it can also drive the sponge block 23 to move towards the wound until the sponge block 23 is attached to the wound. Then, with the operation of the driving assembly 21, the moving assembly 24 is driven by the driving assembly 21 to operate. When the moving assembly 24 operates, it drives the sponge block 23 to move downward. At this time, the sponge block 23 applies medicine to the wound of the patient by moving, thereby realizing complete medicine application to the wound. After the medicine application is completed, the position of the sponge block 23 is maintained. Then, the pushing assembly 32 drives the pressing roller 31 to press the sponge block 23, so as to squeeze out the excess medicine absorbed by the sponge block 23. Therefore, while applying medicine to a long wound, the excess medicine absorbed by the sponge block 23 can also be squeezed out, thus avoiding the problem of medicine dripping from the sponge block 23 and greatly improving the practicability.

[0039] Embodiment 2: Refer to Figures 1-8 , which is different from the above Embodiment 1 in that a bracket 4 is fixedly connected to the outer side of the housing 1. The bracket 4 is composed of a rotating clamping plate 41 and a fixed clamping plate 42 hinged together. The housing 1 communicates with the rotating clamping plate 41. Sponge pads are arranged on the inner sides of the rotating clamping plate 41 and the fixed clamping plate 42. A locking mechanism for fixing the rotating clamping plate 41 is also arranged on the fixed clamping plate 42. The fixing mechanism 5 includes straps 51 arranged at intervals on the outer side of the fixed clamping plate 42, and magic tapes are arranged on the straps 51;

[0040] During use, the fixed clamping plate 42 is brought into contact with the patient's arm. Then, the rotating clamping plate 41 is rotated until the rotating clamping plate 41 and the fixed clamping plate 42 enclose. Then, the rotating clamping plate 41 is fixed on the fixed clamping plate 42 through the locking mechanism on the fixed clamping plate 42, thus completing the wrapping of the patient's arm. Then, the straps 51 are wound around the upper limb trunk of the patient, and then the positions of the housing 1 and the bracket 4 are fixed through the magic tapes on the straps 51.

[0041] Embodiment 3: Refer to Figures 1-8, different from the second embodiment above, the driving assembly 21 includes a connecting rod 211 and a return spring 218. The connecting rod 211 is distributed inside the housing 1. One end of the connecting rod 211 is fixedly connected with a trapezoidal block 212, and the other end of the connecting rod 211 passes through the housing 1 and is fixedly connected with a handle. The inner side of the trapezoidal block 212 is fixedly connected with a connecting spring 213. The end of the connecting spring 213 away from the trapezoidal block 212 is fixedly connected with a pressing block 214. The pressing block 214 is distributed inside the trapezoidal block 212. Symmetrically distributed limiting grooves 215 are formed inside the pressing block 214. A sliding plate 216 is slidably connected inside the limiting grooves 215. A limiting rod 217 is fixedly connected to the sliding plate 216. The end of the limiting rod 217 away from the sliding plate 216 passes through the limiting groove 215 and is fixedly connected to the inside of the trapezoidal block 212. The return springs 218 are distributed on both sides inside the housing 1. One end of the return spring 218 is fixedly connected to the inside of the housing 1, and the other end of the return spring 218 is fixedly connected with a pressing plate 219. The pressing plate 219 is fixedly connected to the connecting rod 211. The medicine delivery assembly 22 includes a rubber plate 221, a connecting pipe 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 inside the inner cavity 223. The inner cavity 223 is formed inside the housing 1. An inlet port 224 and an exhaust port are fixedly connected to the outside of the inner cavity 223. Both the inlet port 224 and the exhaust port are communicated with the inner cavity 223. A protective cap 225 is threadedly connected to the outside of the inlet port 224. An annular plate 2221 is fixedly connected to the inside of the connecting pipe 222. Compression springs 2222 are fixedly connected to the circumference of the annular plate 2221. One end of the compression spring 2222 away from the annular plate 2221 is fixedly connected with a sliding rod 2223. One end of the sliding rod 2223 passes through the annular plate 2221 and is fixedly connected with a sealing plug 2224. A spring thin pipe 2225 is fixedly connected to the outside of the connecting pipe 222. The end of the spring thin pipe 2225 away from the connecting pipe 222 is connected to the sponge block 23. A fixing shell 235 is fixedly connected to the outside of the sponge block 23. A slider 231 is provided on the fixing shell 235. A round head convex rod 232 and a limiting spring 233 are fixedly connected to the outside of the slider 231. The end of the round head convex rod 232 away from the slider 231 is distributed inside the inner cavity 223, and the outside of the round head convex rod 232 is slidably connected with a receiving groove 234. The receiving groove 234 is formed inside the inner cavity 223. When the driving assembly 21 drives the sponge block 23 to fit with the wound, the round head convex rod 232 can move into the receiving groove 234. The moving assembly 24 includes a limiting frame 241 and a moving plate 242. Both the limiting frame 241 and the moving plate 242 are fixedly connected to the outside of the fixing shell 235. The end of the spring thin pipe 2225 away from the connecting pipe 222 is fixedly connected to the fixing shell 235. The slider 231 is slidably connected to the limiting frame 241. A fixing spring 243 is fixedly connected to the inside of the limiting frame 241. The end of the fixing spring 243 away from the limiting frame 241 is fixedly connected to the slider 231. The outside of the moving plate 242 is slidably connected with a limiting hole 244. The limiting hole 244 is formed inside the housing 1.One end of the moving plate 242 away from the sponge block 23 passes through the limiting hole 244 and is distributed inside the housing 1. When the pressing plate 219 moves, it can drive the moving plate 242 to move down along the limiting hole 244;

[0042] In the initial state, the reset spring 218 presses on the pressing plate 219. At this time, the trapezoidal block 212 is located on the inner top surface of the housing 1. At this time, the housing 1 presses on the pressing block 214, so that the pressing block 214 is located inside the trapezoidal block 212. At the same time, the connecting spring 213 is also in a compressed state. When medicine needs to be applied, the feed port 224 is opened. Then, the medicine is pushed into the inner cavity 223 through a syringe. After that, the feed port 224 is closed by the protective cap 225. 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 pressing plate 219, the trapezoidal block 212 and the rubber plate 221 to move. The movement of the rubber plate 221 squeezes the medicine in the inner cavity 223. At this time, the medicine in the inner cavity 223 is squeezed and flows into the connecting pipe 222, and squeezes the sealing plug 2224 on the annular plate 2221. At this time, the sealing plug 2224 is forced to move to the side away from the sliding rod 2223 under the extrusion of the rubber plate 221. The movement of the sealing plug 2224 drives the sliding rod 2223 to move. The movement of the sliding rod 2223 squeezes the compression spring 2222. As the sealing plug 2224 moves, the connecting pipe 222 is opened. At this time, the medicine in the inner cavity 223 enters the spring capillary tube 2225 through the gap between the sealing plug 2224 and the annular plate 2221, and then enters the sponge block 23. At this time, the sponge block 23 absorbs the medicine, thus realizing the delivery of the medicine;

[0043] When the trapezoidal block 212 moves, the trapezoidal block 212 will contact the round-headed convex rod 232 in the inner cavity 223. As the trapezoidal block 212 moves, the trapezoidal block 212 squeezes the round-headed convex rod 232. At this time, the round-headed convex rod 232 moves towards the sponge block 23. The movement of the round-headed convex rod 232 drives the slider 231 to move. The movement of the slider 231 drives the limit frame 241 to move and stretch the limit spring 233. The movement of the limit frame 241 drives the fixed shell 235 to move. The movement of the fixed shell 235 drives the sponge block 23 to move. At this time, the sponge block 23 is pushed and thus fits with the wound. As the trapezoidal block 212 moves, the connecting spring 213 in the trapezoidal block 212 is gradually released. In the initial stage of the movement of the trapezoidal block 212, the connecting spring 213 drives the pressing block 214 to remain in contact with the inner wall of the housing 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. With the cooperation of the limit rod 217, the pressing block 214 moves with the trapezoidal block 212. When the trapezoidal block 212 separates from the round-headed convex rod 232, the pressing block 214 will replace the trapezoidal block 212 and squeeze the round-headed convex rod 232 again, so as to ensure that the sponge block 23 can always fit with the wound. And because the wall thickness of the trapezoidal block 212 is relatively thin, when the pressing block 214 squeezes the round-headed convex rod 232, the sponge block 23 will not retract greatly;

[0044] The movement of the pressing plate 219 will squeeze the return spring 218. And as the connecting rod 211 continuously moves out of the housing 1, the pressing plate 219 will contact the moving plate 242. At this time, as the connecting rod 211 moves, the pressing plate 219 will drive the moving plate 242 to move along the limit hole 244. The movement of the moving plate 242 drives the fixed shell 235 to move along the limit frame 241. The movement of the fixed shell 235 drives the sponge block 23 to move. At this time, the sponge block 23 applies 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 limit spring 233 and the fixed spring 243, the connecting rod 211, the round-headed convex rod 232 and the fixed shell 235 all return to their initial positions.

[0045] It should be noted that the elastic force of the return spring 218 is greater than the elastic force of the connecting spring 213.

[0046] Example 4: Refer to Figures 1-8 , different from the above Example 3, the pushing assembly 32 includes a mounting frame 321, a push rod 323 and a feeding port 322. The extrusion roller 31 is installed inside the mounting frame 321. The mounting frames 321 are distributed inside the housing 1. The top end of the push rod 323 passes through the housing 1 and is fixedly connected to the mounting frame 321. A return spring 325 is fixedly connected to the push rod 323. The 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 opened on the rotating clamping plate 41;

[0047] 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.

[0048] 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 .

[0049] 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.
