Description

Technical Field

[0001] This invention relates to the field of physical examination tools, and more specifically, to a portable neurological physical examination structure. Background Technology

[0002] In neurological clinical examinations, various specialized tools such as percussion hammers, percussion pinwheels, tuning forks, and 10G nylon wires are required to perform multiple examinations, including those assessing nerve reflexes, touch, and pain. Currently, most clinical examination tools are separate, independent structures. Medical staff must carry multiple instruments during outpatient visits and ward rounds, which is cumbersome to store and carry, and prone to loss or omission, significantly reducing examination efficiency. Existing integrated examination structures simply have slots to store various accessories; their design is rudimentary and has obvious safety flaws. Percussion pinwheels, being sharp components, are mostly covered or have a swing-open / close mechanism. The former can completely seal the pinwheel, but it's inconvenient for integrating with other tools and requires repeated opening and closing, making operation cumbersome. The latter, however, remains visible even after storage, potentially causing injury due to accidental contact during carrying, storage, and operation; this design needs improvement.

Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 6 As shown, a portable neurological examination structure is disclosed in a specific embodiment of the present invention, including a percussion hammer 100, a percussion wheel 200, and a sealing component 300; the percussion hammer 100 includes a hammer head 110, a hammer body 120, and a handle 130 connected in sequence, and a first groove 140 is provided at the connection between the hammer body 120 and the hammer head 110, with one end of the first groove penetrating the outer wall of the hammer head; the percussion wheel 200 is movably mounted on the hammer body 120, and the percussion wheel 200 has a spiked wheel 210. At the first groove 140; the sealing member 300 is movably mounted on the hammer body 120, and one end of the sealing member 300 is provided with a baffle 310, which is located at the first groove 140 and is used to block the end opening of the first groove; the handle 220 of the pin wheel 200 is linked with the sealing member 300. When the pin wheel is pushed outward, the baffle retracts and releases the blockage of the end opening of the first groove; when the pin wheel is retracted inward, the baffle moves forward and restores the blockage of the end opening of the first groove. The aforementioned portable neurological examination structure utilizes a percussion hammer as the main component, providing mounting slots for other structural components, resulting in a more compact and portable overall structure. The percussion hammer and the sealing component can work in tandem; when the percussion hammer is extended, the baffle opens simultaneously, allowing the hammer to move smoothly to the desired location. When the hammer is retracted, the baffle moves simultaneously to seal, protecting the hammer and effectively preventing accidental contact and injury. Overall, the structure is simple and convenient to use.

[0019] Furthermore, a second groove 150 is provided on the other side wall of the hammer body 120 opposite to the first groove. One end of the second groove extends to the handle. The second groove 150 is used to accommodate the tuning fork 400. The tuning fork can be completely detached and removed for convenient actual use. The handle slides against the wall of the first groove on one side; the handle slides close to the wall of the hammer body, and the bottom of the second groove 150 is provided with a first strip hole 151 through it. A first bolt 230 is installed on the handle 220, and the handle 220 slides along the first strip hole 151 via the first bolt 230. The above structural design can initially limit the movement of the tile needle wheel, so that it can move smoothly in the required direction. A first rubber pad 240 is fixedly provided on the wall surface of the handle 220 away from the first strip hole 151. The wall surface of the first rubber pad away from the first strip hole is an inclined surface, and it is inclined downward at the end towards the hammer head. The lower end of the inclination of the first rubber pad is lower than the groove wall of the first groove. When the pin wheel is pushed forward until the first bolt is stuck at the end of the first strip hole, the handle is stuck in the first groove through the first rubber pad and will not easily loosen, maintaining the state of the pin wheel protruding out of the outside of the hammer head for inspection and use. A third groove 160 is provided on the wall surface of the first groove 140 away from the end opening. The third groove extends along the length of the hammer body, and the side of the third groove away from the second groove is open. A second strip-shaped hole 161 is provided through the bottom of the third groove 160. The sealing member 300 includes a support strip 320, and a baffle 310 is fixedly provided at one end of the support strip 320. The shape of the support strip 320 is adapted to the shape of the third groove 160, and the support strip slides close to the bottom and two walls of the third groove. A second bolt 330 is installed on the support strip 320, and the support strip 320 slides along the second strip-shaped hole 161 via the second bolt 330. The above structural design can limit the movement trajectory of the sealing member, so that it can move smoothly in the required direction. Moreover, the handle and the support strip are linked and cooperated, which can not only meet the required opening and closing action, but also limit the movement of the tile needle wheel to a certain extent, so that it moves in the required direction.

[0020] Furthermore, the handle 220 has a first toothed groove 221 on the wall near the third groove, extending along the length of the third groove; the support bar 320 has a second toothed groove 321 on the wall near the handle, extending along the length of the support bar; a gear 500 is rotatably installed inside the third groove 160, and both the first toothed groove 221 and the second toothed groove 321 mesh with the gear 500 for transmission; the arrangement of the first toothed groove and the second toothed groove makes the handle and the support bar function like a rack and pinion, and with the cooperation of the gear, they can achieve synchronous and divergent movements, which can satisfy the following effects: when pushing the spike wheel outward, the baffle retracts and releases the blockage of the opening at the end of the first groove; when retracting the spike wheel inward, the baffle moves forward and restores the cover of the opening at the end of the first groove; wherein, the third groove has a through hole penetrating the two opposite side walls for mounting the rotating shaft, and the gear is rotatably mounted on the rotating shaft; Furthermore, a limiting plate 600 is installed inside the first groove 140, and the distance between the limiting plate and the groove wall of the first groove is adapted to the width of the baffle; as Figure 7 As shown, a limiting strip 610 is fixedly provided on the wall surface of the limiting plate 600 near the baffle. The limiting strip is located at the bottom of the end of the limiting plate away from the third groove. A limiting groove 620 is provided on the limiting strip 610, and the cross-section of the limiting groove is arc-shaped. The baffle 310 is movably inserted through the limiting groove 620. When the baffle moves outward, it is guided to bend through the limiting groove to block the end opening of the first groove. The limiting plate adopts a detachable structure, which ensures that the mounting space required for the pin wheel and the sealing component is left. In particular, the setting of the limiting groove can provide the guiding conditions for the deformation of the baffle, so that the baffle can deform to block the port of the first groove when the sealing component moves outward.

[0021] Furthermore, the wall surface of the limiting plate 600 away from the limiting strip is flush with the outer wall of the hammer body, and a gap is left between it and the groove wall of the first groove to form a channel; a pusher 700 is movably installed on the hammer body 120, and a 10G nylon filament 710 is clamped on the pusher 700, with the 10G nylon filament corresponding to the channel; pushing the pusher outward is used to drive the 10G nylon filament to extend out of the first groove; on the original basis, another 10G nylon filament is integrated for pressure sensation testing, further increasing the physical examination function; and this component shares the space of the first groove, which also facilitates the overall layout design; The pusher 700 has a second rubber pad 720 fixedly installed on the wall surface away from the hammer body. The wall surface of the second rubber pad away from the second strip hole is an inclined surface, and it is inclined downward at the end towards the hammer head. The lower end of the inclination of the second rubber pad is lower than the groove wall of the second groove. When the 10G nylon filament is pushed forward to the preset position, the pusher is locked in the first groove by the second rubber pad and will not easily loosen, maintaining the state of the 10G nylon filament protruding from the outside of the hammer head for inspection and use.

[0022] Furthermore, a push rod 730 is fixedly provided at one end of the push frame 700, and the shape of the push rod is adapted to the shape of the channel; the push frame slides close to the wall of the hammer body, and one side of the push frame slides against the side wall of the handle; a third strip hole 152 is provided through the bottom of the second groove 150, and a third bolt 750 is installed on the push frame 700, and the push frame 700 slides along the third strip hole 152 via the third bolt 750; with this cooperation, the movement trajectory of the push frame can be effectively limited, so that it can only move along the third strip hole; in addition, the push frame can also limit the handle of the tile needle wheel, so that the handle can only move along the extension direction of the first strip hole, satisfying the required pushing effect; the end of the push rod 730 is provided with a first slot 740, and the shape of the 10G nylon wire clip is adapted to the shape of the first slot and they are engaged with each other; this facilitates the disassembly and assembly of the 10G nylon wire for replacement.

[0023] Furthermore, a first magnet 171 and a second magnet 172 are fixedly embedded on the side wall of the hammer body 120 at the outer ends of the first and third strip holes; a third magnet 222 is fixedly embedded on the end wall of the handle 220; a fourth magnet 760 is fixedly embedded on the end wall of the pusher 700; when the spike wheel is retracted into the first groove, the third magnet is magnetically connected to the first magnet; when the 10G nylon wire is retracted into the first groove, the fourth magnet is magnetically connected to the second magnet. This structural design can facilitate the maintenance of basic positioning effect of the pin wheel and the 10G nylon wire in the retracted state, so that the two will not easily loosen or shift; especially under the linkage effect of the pin wheel and the sealing component, the pin wheel will not easily loosen or shift.

[0024] Furthermore, the hammer body 120 has two opposite sidewalls with first threaded holes 121, which communicate with the second groove and are located at the end closer to the first groove; the end face of the second groove 150 away from the first groove has a first recessed groove 153; a ball bearing 800 is installed at the first threaded hole 121, and the ball bearing extends into the second groove; the outer wall surface of the two forks of the tuning fork 400 has a corresponding second recessed groove 410; the shape of the end of the fork handle of the tuning fork matches the shape of the first recessed groove; the end of the fork handle of the tuning fork is inserted into the first recessed groove, and the fork head of the tuning fork is secured in the second groove by the ball bearing; this structural design can effectively limit the tuning fork, so that it can be relatively securely locked in the second groove after installation and will not easily loosen or fall off; when it is necessary to remove the tuning fork for use, the elasticity of the ball bearing can be overcome, which also makes it easy to remove; the position of the first threaded hole corresponds to the opening range of the through hole, and the first threaded hole can be used as the part for inserting the pivot.

[0025] Furthermore, threaded posts 170 are fixedly provided in the middle of the two opposite walls of the hammer head 110. A first end cap 910 is installed on one of the threaded posts. The end of the first end cap has an outwardly convex arc shape and can be used as the main part for percussion. A second end cap 920 is installed on the other threaded post. The end of the second end cap has a flat head shape and can be used to strike a tuning fork. Of course, the two effects are not mutually exclusive and can be operated as needed. Moreover, the above structure can facilitate the disassembly and assembly of the first end cap and the second end cap, making it easy to replace and use. Furthermore, the percussion hammer can be made of, but is not limited to, medical-grade ABS, PP, or PC, which provides sufficient hardness to ensure adequate structural strength and facilitates injection molding for the formation of various structural components, thus simplifying actual production and processing. The protruding portion of the first end cap is made of TPE or TPR, providing deformation elasticity; these are commonly used materials for the striking end of clinical percussion hammers, and will not be elaborated upon further. The second end cap can also be made of medical-grade ABS, PP, or PC, providing sufficient structural strength. Furthermore, a rubber head 921 is fixedly provided on the end face of the second end cap 920, and the rubber head has a planar structure; the end face of the handle 130 away from the hammer body is provided with a second threaded hole 131, and a metal end 930 is installed at the second threaded hole 131, and the end face of the metal end is planar; with this combination, it is equivalent to integrating the temperature sensing physical examination function, using the temperature difference between the rubber head and the metal end to achieve the required physical examination effect; wherein, the rubber head is including but not limited to one of nylon, ABS or polycarbonate, with a low thermal conductivity and an inconspicuous cooling sensation; the center of the end face of the metal end is provided with a fourth groove for fitting and holding a screwdriver, which facilitates the disassembly and assembly of the metal end; the metal end is made of aluminum alloy, which has better thermal conductivity and produces a more obvious cooling sensation; thus forming a more obvious temperature difference stimulation in order to provide the required detection effect.
