Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a plastic upper limb reinforcement and fixation splint. Background Art

[0002] An upper limb augmentation splint is a medical device used to immobilize and support the upper limbs (such as the arms and wrists) to help treat fractures, sprains, dislocations, or post-operative rehabilitation. The main function of this type of splint is to provide fixation and support for the injured or post-operative upper limbs to promote healing and recovery of function.

[0003] The upper limb polymer material fixation splints in the existing technology are generally manufactured through a universal mold and have a fixed shape. The material is then covered on the affected part of the upper limb and hardens after contact with the air. The splint is not breathable where it directly contacts the skin. When the splint needs to be removed, a special cutter must be used to cut off the splint, which makes the fixation and removal of the splint very inconvenient. Secondly, the splint is reinforced and fixed to the patient's wrist again with a strap, and is subsequently hung on the patient's neck with a sling for a long time, which easily leads to poor flexibility of the patient's elbow joint. In order to alleviate this phenomenon in the patient's elbow, doctors usually arrange for the patient to wear the splint and perform appropriate flexion and extension exercises of the elbow while allowing the patient's arm to flex and extend appropriately. However, during the flexion and extension exercise, the muscles on both sides of the elbow swell, causing the elbow end of the splint to rub against its elbow, affecting the patient's comfort during arm flexion and extension exercises. Therefore, the present application provides a plastic upper limb reinforcement fixation splint to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a plastic upper limb reinforcement fixation splint by arranging a clamping part, an auxiliary curing part and an extrusion massage part. The clamping part enables the mounting sleeve to be quickly installed at the elbow end of the splint. Secondly, the auxiliary curing part can inject a mixed material, such as liquid medical resin plaster, into the flow cavity. After the resin plaster is cured, the splint can be directly fixed without the need for further reinforcement through a strap. Furthermore, the extrusion massage part can massage the patient's elbow when the patient's elbow is flexed and extended, and can also inflate the deflated expansion airbag while massaging. Through the above, the problem that when the patient wears the splint to perform appropriate flexion and extension of the elbow, the elbow end of the splint will rub against the elbow, affecting the patient's comfort during arm flexion and extension exercises can be solved.

[0013] Optionally, a plurality of movable blocks arranged in a ring array are fixed to a side wall of the movable ring away from the plurality of square rods, the number of the plurality of movable blocks is less than the number of the plurality of square rods, and one end of the plurality of movable blocks away from the movable ring is movably extended to the outside of the mounting sleeve, and is fixed to the same push plate with an arc-shaped structure, and the bottom end of the push plate is integrally formed with an extrusion spring piece with a C-shaped vertical cross-section, and a weakening groove is provided on the inner wall of the connection between the extrusion spring piece and the bottom end of the push plate, and the extrusion spring piece is fixed to the outside of the pressurized airbag.

[0014] Optionally, a relief opening is provided on the top of the extrusion spring, and the relief opening is used to expose the air inlet nozzle on the top of the pressurized airbag.

[0015] Optionally, a plurality of extrusion blocks arranged in a circular array are fixedly connected to a side wall of the movable ring facing the plurality of square rods, each of the extrusion blocks is located between each two adjacent guide columns, and transmission grooves are provided through the plurality of square rods, and a first inclined surface is provided on an inner wall of each of the plurality of transmission grooves close to the massage balls, and a corresponding second inclined surface is provided on one end of each of the plurality of extrusion blocks facing the first inclined surface.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by providing the clamping piece, the mounting sleeve can be quickly mounted and fixed at the elbow end of the splint body.

[0018] By setting up an auxiliary curing part, a mixed material, such as liquid medical resin plaster, can be injected into the flow cavity through an injection tube. After the resin plaster is cured, the splint can be fixed directly without the need for further reinforcement through straps, making the fixation of the splint very convenient, quick and sustainable.

[0019] By setting up a squeezing massage part, since the inflatable airbag needs to be manually pressed by medical staff to inflate the inflatable airbag when it is used for the first time, during the inflating process, the one-way valves on the two air inlet pipes need to be manually opened, and the one-way valve on the exhaust pipe needs to be manually closed. At this time, the pressurized airbag can inflate the inflatable airbag while the medical staff manually presses the squeezing shrapnel, and inflate it to a comfortable expansion degree for the patient. After that, due to the long-term use of the inflatable airbag, it will be deflated in the later stage and it needs to be re-filled with air. In addition, the patient can perform elbow flexion and extension exercises under the doctor's advice, and through the flexion and extension exercises of the elbows, the squeezing shrapnel will be squeezed by the bending of the elbow. During the squeezing process The pressurized airbag is squeezed and deformed, and the expansion airbag can be inflated to a comfortable expansion degree for the patient to ensure that the patient's elbow is not easily rubbed against the elbow end of the splint body, greatly improving the comfort of the patient when wearing the splint body. In addition, during the squeezing of the extrusion spring, the push plate will push the moving ring connected to the multiple movable blocks to move outside the multiple guide columns, and at the same time, the moving ring drives the second inclined surface of the multiple extrusion blocks to squeeze the corresponding first inclined surface in the transmission groove, thereby prompting the square rod to drive the massage ball to move toward the center of the mounting bracket, and simultaneously realize the massage of the patient's elbow, avoiding the problem of poor flexibility of the patient's elbow joint due to the splint being hung on the patient's neck by a sling for a long time.

[0040] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a plastic upper limb reinforcement fixation splint, comprising a splint body 1, a manual opening 11 is opened at the bottom of the splint body 1, the two ends of the splint body 1 are respectively a wrist end and an elbow end, the diameter of the elbow end is larger than the diameter of the wrist end, and a mounting sleeve 2 with a circular ring structure is sleeved on the elbow end, the cross section of the mounting sleeve 2 is a convex structure, and the mounting sleeve 2 is fixed to the elbow end by a plurality of clamping members arranged in a ring array, and an expansion airbag 3 with a vertical C-shaped structure is fixedly connected to the end of the mounting sleeve 2 away from the plurality of clamping members, and the two ends of the expansion airbag 3 A pressurized airbag 4 with an arc-shaped structure is provided in between, which is fixed to the mounting sleeve 2. An air inlet nozzle 41 is provided on the top surface of the pressurized airbag 4, and an exhaust pipe 42 is provided on the side surface of the pressurized airbag 4 facing the clamping part. The air outlets at both ends of the pressurized airbag 4 are connected to the interior of the expansion airbag 3 through the air inlet pipe 43, and the two air inlet pipes 43 and the exhaust pipe 42 are provided with a one-way valve. The splint main body 1 is installed with an auxiliary curing part; it also includes an extrusion massage part 5, which is installed on the mounting sleeve 2. The extrusion massage part 5 is used to synchronously achieve massage and inflation with the help of the flexion and extension activities of the patient's elbow joint.

[0041] Among them, the splint body 1 can be made of ABS plastic material. It is worth noting that when the air in the inflatable airbag 3 is filled to a state where the patient feels comfortable, the one-way valves on the two air inlet pipes 43 can be closed and the one-way valve on the exhaust pipe 42 can be opened, so that the air in the pressurized airbag 4 during the squeezing process can be discharged through the exhaust pipe 42. Figure 1 The port at the wrist end shown in the figure is provided with a reserved groove for fixing the thumb.

[0042] like Figures 1 to 2 As shown, the splint body 1 is provided with a plurality of vents in a diamond-shaped structure.

[0043] The provision of the vent can ensure ventilation between the inner wall of the splint and the muscles of the patient's hand when the splint body 1 is used on the patient's hand.

[0044] like Figures 1 to 2 As shown, in order to facilitate the rapid fixation of the splint body 1, the auxiliary curing component is provided to include a flow cavity provided inside the splint body 1, an injection pipe 12 is fixedly connected to the liquid inlet on the outer wall of the splint body 1, and a sealing cover 13 is threadedly connected to the opening of the injection pipe 12.

[0045] Among them, the sealing cap 13 can ensure that the mixed material such as resin plaster is not easy to flow out due to the movement of the patient's arm after injection. By unscrewing the sealing cap 13, since the injection tube 12 is connected to the flow cavity, the user can manually inject the liquid resin plaster into the flow cavity from the outer end opening of the injection tube 12 through the syringe.

[0046] like Figures 2 to 6 as well as Figure 11 As shown, in order to enable the mounting sleeve 2 to be quickly installed on the splint body 1, a clamping member is provided, including a connecting piece 21 fixed to the side of the mounting sleeve 2 away from the pressurized airbag 4, and a through groove is provided on the connecting piece 21. A clamping spring 22 is fixed to the inner wall of the through groove on the side away from the pressurized airbag 4, and the other end of the clamping spring 22 is tilted and tilted toward the center of the mounting sleeve 2 when the mounting sleeve 2 is not installed on the splint body 1.

[0047] Among them, the mounting sleeve 2 needs to be put on the patient's hand before the splint main body 1 is installed. Then, after the splint main body 1 is opened and put on the patient's hand, the clamping piece on the mounting sleeve 2 is used to achieve fixation between it and the splint main body 1. Specifically, before the mounting sleeve 2 is installed, one end of the clamping spring 22 is tilted and tilted toward the center of the mounting sleeve 2. After installation, the tilted and tilted end of the clamping spring 22 will press against the outer wall of the splint main body 1. At this time, the tilted and tilted end of the clamping spring 22 will be squeezed into the through groove by the outer wall of the splint main body 1. Under the reverse action of the tilted and tilted end of the clamping spring 22, the clamping and fixation between the mounting sleeve 2 and the splint main body 1 is achieved.

[0048] like Figures 2 to 10As shown, in order to enable the patient to flex and extend the elbow under the doctor's advice, on the one hand, by means of the flexion and extension movement of the elbow, the deflated inflatable airbag 3 can be inflated to a comfortable state for the patient, and on the other hand, the patient's elbow can be massaged at the same time, so the extrusion massage member 5 is provided, including an annular inner cavity opened on the inner side of the mounting sleeve 2, a plurality of guide posts 58 arranged in an annular array are fixedly connected to the annular inner cavity, the outer sliding sleeves of the plurality of guide posts 58 are provided with a same movable ring 57, and one side of the movable ring 57 is also provided. There are multiple square rods 59 arranged in a circular array. One end of the multiple square rods 59 facing the center of the mounting sleeve 2 is movable and penetrates the outside of the mounting sleeve 2, and is fixed with a massage ball 510. The ends of the multiple square rods 59 away from the massage ball 510 are fixed to the inner wall of the annular inner cavity through a reset spring 511 with a funnel-shaped structure in a vertical section. A plurality of movable blocks 55 arranged in a circular array are fixed on one side wall of the movable ring 57 away from the multiple square rods 59. The number of the multiple movable blocks 55 is less than the number of the multiple square rods 59. One end of the movable block 55 away from the movable ring 57 is movably extended to the outside of the mounting sleeve 2 and is fixedly connected to a push plate 54 with the same arc-shaped structure. The bottom end of the push plate 54 is integrally formed with an extrusion spring 51 with a vertical cross-section C-shaped structure. A weakening groove 56 is provided on the inner wall of the connection between the extrusion spring 51 and the bottom end of the push plate 54. The extrusion spring 51 is fixed to the outside of the pressurized airbag 4. The top of the extrusion spring 51 is provided with an avoidance opening 52. The avoidance opening 52 is used to expose the air inlet nozzle 41 at the top of the pressurized airbag 4. The extrusion spring 51 is also provided with a plurality of grooves along the A lightweight groove 53 is arranged in an array in the shape of an extrusion spring 51, and a plurality of extrusion blocks 512 arranged in a ring array are fixedly connected to one side wall of the movable ring 57 facing the plurality of square rods 59. Each extrusion block 512 is located between each two adjacent guide columns 58. A transmission groove 513 is opened through the plurality of square rods 59. A first inclined surface 514 is opened on an inner wall of each of the plurality of transmission grooves 513 close to the massage ball 510, and a corresponding second inclined surface 515 is opened on one end of each of the plurality of extrusion blocks 512 facing the first inclined surface 514.

[0049] Among them, the shape of the extrusion spring 51 is more in line with the shape of the pressurized airbag 4. In order to enable the pressurized airbag 4 to quickly return to its original state after being squeezed, thereby facilitating subsequent squeezing, the reset spring 511 is set to enable the square rod 59 to reset after the telescopic movement. The lightweight groove 53 is set to reduce the weight of the extrusion spring 51. The second inclined surface 515 on the extrusion block 512 is in a parallel state with the first inclined surface 514 in the transmission groove 513 in the initial state. When the second inclined surface 515 on the extrusion block 512 moves toward the direction of the transmission groove 513, it squeezes the first inclined surface 514 in the transmission groove 513, so that the square rod 59 drives the reset spring 511 to stretch, and the massage ball 510 touches the patient's elbow, thereby achieving the purpose of massage.

[0050] The workflow of the technical solution of the present invention is as follows:

[0051] Step 1: The medical staff first puts the mounting bracket 2 on the outside of the patient's elbow, and at the same time, opens the splint body 1 through the manual opening 11 and puts it on the outside of the patient's elbow. After that, the mounting bracket 2 can be clamped and fixed to the outside of the elbow end of the splint body 1 through multiple clamping parts;

[0052] Step 2: The medical staff manually presses the pressurized airbag 4 to inflate the expansion airbag 3. During the inflation process, the one-way valves on the two air inlet pipes 43 need to be manually opened, and the one-way valve on the exhaust pipe 42 needs to be manually closed. At this time, the pressurized airbag 4 can inflate the expansion airbag 3 while the medical staff manually presses the extrusion spring 51. The airbag 3 is inflated to a comfortable expansion degree for the patient. After that, the sealing cover 13 knob is removed, and a syringe pre-loaded with resin plaster is taken out. The resin plaster is injected into the flow cavity from the injection tube 12. After the resin plaster is solidified, a fixed splint is formed to play a fixing role.

[0053] Step 3: After the above-mentioned splint main body 1 is used, the inflatable airbag 3 will definitely be deflated in the later stage due to long-term use, and it needs to be refilled with air. The patient can perform elbow flexion and extension exercises according to the doctor's instructions, and through the flexion and extension of the elbow, the extrusion spring 51 will be squeezed by the bending of the elbow. During the squeezing process, the pressurized airbag 4 is squeezed and deformed, and the inflatable airbag 3 can be inflated to a comfortable expansion degree for the patient to ensure that the patient's elbow is not easy to rub against the elbow end of the splint main body 1, thereby greatly improving the patient's comfort when wearing the splint main body 1. During the squeezing process of the squeezing spring 51, the push plate 54 will push the movable ring 57 connected to the multiple movable blocks 55 to move outside the multiple guide pillars 58, and at the same time, the movable ring 57 drives one end of the second inclined surface 515 on the multiple squeezing blocks 512 to squeeze the corresponding first inclined surface 514 in the transmission groove 513, thereby prompting the square rod 59 to drive the massage ball 510 to move toward the center of the mounting sleeve 2, and simultaneously realize the massage of the patient's elbow, avoiding the problem of poor flexibility of the patient's elbow joint due to the splint being hung on the patient's neck through a sling for a long time.

[0054] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
