Description

Technical Field

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

[0002] An upper limb enhancement splint is a device used in the medical field, mainly used to fix and support the upper limbs (such as arms and wrists) to help treat fractures, sprains, joint dislocations or post-operative rehabilitation. The main function of this type of splint is to provide fixation and support for the upper limbs after injury or surgery to promote healing and recovery of function.

[0003] The upper limb polymer material fixation splints in the prior art 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 needs to 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 suspended on the patient's neck with a sling for a long time, which can easily lead 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 on the premise that the patient's arm is allowed 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 the elbow, affecting the patient's comfort during arm flexion and extension exercises. Therefore, the present application provides a plastic upper limb enhancement fixation splint to meet the demand. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a plastic upper limb enhancement 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 re-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 the elbow end of the splint will rub against the elbow when the patient wears the splint to perform appropriate flexion and extension of the elbow, thereby affecting the patient's comfort during arm flexion and extension exercises can be solved.

[0040] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a plastic upper limb enhancement fixation splint, including 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 end of the mounting sleeve 2 away from the plurality of clamping members is fixedly connected to an inflatable airbag 3 with a C-shaped structure in vertical section, and both ends of the inflatable airbag 3 A pressurized airbag 4 with an arc-shaped structure fixedly connected to the mounting sleeve 2 is provided in between, an air inlet nozzle 41 is provided on the top surface of the pressurized airbag 4, an exhaust pipe 42 is provided on the side surface of the pressurized airbag 4 facing the clamping member, air outlets at both ends of the pressurized airbag 4 are connected to the interior of the expansion airbag 3 through an air inlet pipe 43, and both air inlet pipes 43 and the exhaust pipe 42 are provided with a one-way valve, and the splint 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, and is used to synchronously achieve massage and inflation with the help of the flexion and extension activities of the patient's elbow joint.

[0041] 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 A reserved groove for fixing the thumb is provided at the port at the wrist end shown in the figure.

[0042] like Figure 1 to Figure 2 As shown, the clamping plate 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 Figure 1 to Figure 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 of 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 a syringe.

[0046] like Figures 2 to 6 as well as Fig.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 fixedly connected to the side of the mounting sleeve 2 away from the pressurized airbag 4, and a through groove is opened on the connecting piece 21. A clamping spring piece 22 is fixedly connected 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 piece 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 realize the 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 realized.

[0048] like Figures 2 to 10As shown, in order to enable the patient to perform elbow flexion and extension activities under the doctor's advice, on the one hand, by means of the elbow flexion and extension movement, 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 to include an annular inner cavity opened on the inner side of the mounting sleeve 2, and a plurality of guide columns 58 arranged in an annular array are fixedly connected in the annular inner cavity, and the outer sliding sleeves of the plurality of guide columns 58 are provided with a same moving ring 57, and one side of the moving ring 57 is also A plurality of square rods 59 are arranged in a circular array, and one end of the plurality of square rods 59 facing the center of the mounting sleeve 2 is movable and penetrates the outside of the mounting sleeve 2, and is fixedly connected with a massage ball 510. One end of the plurality of square rods 59 away from the massage ball 510 is fixedly connected 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 fixedly connected to a side wall of the movable ring 57 away from the plurality of square rods 59. The number of the plurality of movable blocks 55 is less than the number of the plurality of square rods 59. One end of the moving block 55 away from the moving ring 57 is movably extended to the outside of the mounting sleeve 2, and is fixedly connected to the same push plate 54 with an arc-shaped structure. The bottom end of the push plate 54 is integrally formed with an extrusion spring piece 51 with a C-shaped structure in vertical section. A weakening groove 56 is provided on the inner wall of the connection between the extrusion spring piece 51 and the bottom end of the push plate 54. The extrusion spring piece 51 is fixed to the outside of the pressurized airbag 4. The top of the extrusion spring piece 51 is provided with an avoidance opening 52, which is used to expose the air inlet nozzle 41 at the top of the pressurized airbag 4. The extrusion spring piece 51 is also provided with a plurality of grooves along the edge. 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 a 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. Transmission grooves 513 are penetrated through the plurality of square rods 59. A first inclined surface 514 is provided on an inner wall of each of the plurality of transmission grooves 513 close to the massage ball 510, and a matching second inclined surface 515 is provided on one end of each of the plurality of extrusion blocks 512 facing the first inclined surface 514.

[0049] Among them, the shape setting of the extrusion spring piece 51 is more in line with the shape of the pressurized airbag 4. In order to enable the pressurized airbag 4 to quickly restore to its original state after being squeezed, so as to facilitate subsequent squeezing again, the setting of the reset spring piece 511 is to enable the square rod 59 to be reset after the telescopic movement. The setting of the lightweight groove 53 is to reduce the weight of the extrusion spring piece 51. The second inclined surface 515 on the extrusion block 512 is in a level 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 piece 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 sets the installation sleeve 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 sets it on the outside of the patient's elbow. After that, the installation sleeve 2 can be clamped and fixed on 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 inflating 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, and inflate the expansion airbag 3 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, and the resin plaster is injected into the flow cavity from the injection tube 12. After the resin plaster is cured, a fixed splint is formed to play a fixing role;

[0053] Step 3: After the above-mentioned splint body 1 is used, since the long-term use of the inflation airbag 3 will definitely be deflated in the later stage, it needs to be refilled with air, and 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 inflation 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 body 1, which greatly improves the comfort of the patient when wearing the splint body 1. During the squeezing process of the squeezing spring piece 51, the push plate 54 will push the moving ring 57 connected to the multiple movable blocks 55 to move outside the multiple guide pillars 58, and at the same time, the moving 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, so as to avoid 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 covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not 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 principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
