Description

Technical Field

[0001] The invention relates to the technical field of medical examination lifting equipment, and in particular to a neurology examination lifting device. Background Art

[0002] Neurology is a secondary discipline concerning neurology and does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases, migraines, myelitis and other diseases. During neurology examinations, doctors need to conduct sensory experiments to determine whether there are abnormalities in the nervous system.

[0003] When doctors examine the patient's limbs, since the patient's limbs cannot move on their own, they usually need to lift the patient's limbs and then examine the lifted limbs. Since there are many items to be examined, such as pain examination, tactile examination, reflex condition examination, etc., it is necessary to rely on a lifting device to lift the patient's limbs. The prior art mentions a lifting device for neurological examination, which includes a bed, and both sides of the top of the bed are provided with a rotating groove, and a rotating seat is provided inside the rotating groove. The lifting device for neurological examination can automatically lift the patient's legs through the coordination of a fixed frame, a third electric telescopic rod, a third transmission plate, a clamp, a connecting rope, and an elastic rope. Although the above structure can avoid the doctor from always lifting the patient's limbs by himself, when the above device lifts the patient's limbs, since the fixed point is to lift the patient's limbs with the end of the patient's limbs as the support point, the limbs cannot rotate around the joints of the lifted limbs. When a knee jerk reflex experiment is required, the patient's forearm or calf still needs to be manually bent to perform the experiment.

[0004] In order to solve the above problems, a lifting device for neurological examination is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] refer to Figures 1 to 6 , a neurological examination lifting device, comprising an n-shaped bed board 1, a thigh support board 5, a calf support board 4, a rotating board 10, an upper arm support board 22, a lower arm support board 11, a driving mechanism, a leg lifting mechanism, a knee joint bending mechanism, an upper limb rotating mechanism, and an elbow joint bending mechanism; Thigh support plates 5 are movably mounted on both sides of the middle of the top wall of the horizontal plate of the n-shaped bed plate 1, and the two thigh support plates 5 are driven to rotate by the leg lifting mechanism; the n-shaped bed plate is used to support the patient's torso, and the thigh support plates 5 are used to support the user's thighs; The front sides of the two thigh support plates 5 are respectively rotatably mounted with calf support plates 4, and the two calf support plates 4 are both driven to move by the knee joint bending mechanism. The two thigh support plates respectively drive the two knee joint bending mechanisms to work by rotation, and the calf support plates 4 are used to support the user's calves. With the drive of the knee joint bending mechanism, the calf support plates 4 will bend downward, thereby making the user's calves bend downward, which is convenient for doctors to perform knee jerk reflex tests on the patient's knee joints; The two sides of the first end of the horizontal plate of the n-shaped bed plate 1 are respectively installed with driving mechanisms, and the two leg-lifting mechanisms are driven to work by the two driving mechanisms respectively, and the leg-lifting mechanisms will start working under the drive of the driving mechanisms; Two rotating plates 10 are rotatably mounted on the upper part of the second end of the horizontal plate of the n-shaped bed plate 1, and the two rotating plates 10 are driven to rotate by the upper limb rotating mechanism respectively. The two thigh support plates 5 drive the two upper limb rotating mechanisms to work by rotating respectively, and the rotating plates 10 are used to drive the upper arm support plate 22 to start rotating under the drive of the upper limb rotating mechanism; The upper parts of the first ends of the two rotating plates 10 are respectively fixedly mounted with upper arm support plates 22, and the front ends of the two upper arm support plates 22 are respectively rotatably mounted with the lower arm support plates 11, and the two lower arm support plates 11 are respectively driven to rotate by the elbow joint bending mechanism, the upper arm support plates 22 are used to support the upper arms of the patient, and the lower arm support plates 11 are used to support the lower arms of the patient, and the upper arm support plates 22 will start to rotate with the rotating plates 10 and drive the lower arm support plates 11 to start to lift upwards through the elbow joint bending mechanism during the rotation process; The two rotating plates 10 respectively drive the two elbow joint bending mechanisms to work by rotating.

[0024] The leg lifting mechanism comprises an n-shaped slider 13, a first connecting rod 3, and a first mounting plate 102; The first mounting plates 102 are respectively installed on both sides of the middle of the top wall of the horizontal plate of the n-shaped bed plate 1, and the outer first ends of the two thigh support plates 5 are respectively rotatably arranged on the inner walls of the two first mounting plates 102 through the first rotating shaft; The two first rotating shafts respectively drive the two upper limb rotating mechanisms to work by rotating; A second rotating shaft is respectively installed on the outer sides of the second ends of the two thigh supporting plates 5; The first ends of the first connecting rods 3 are rotatably mounted on the outer sides of the two second rotating shafts respectively; N-shaped sliders 13 are slidably mounted on both sides of the first end of the horizontal plate of the n-shaped bed plate 1, and two vertical rods of the two n-shaped sliders 13 are respectively clamped outside the two side walls of the n-shaped bed plate 1; The outer walls of the transverse plates of the two n-shaped sliders 13 are respectively provided with third rotating shafts, and the second ends of the two first connecting rods 3 are respectively rotatably sleeved on the outer sides of the two third rotating shafts; The two n-type sliders 13 are driven to slide by two driving mechanisms respectively. The two n-type sliders 13 start to slide back and forth under the driving of the driving mechanisms. Figure 2 When the two n-shaped sliders 13 slide to the right, the first connecting rod 3 located on the outer side of the horizontal plates of the two n-shaped sliders 13 begins to deflect upward, and in the process of deflection, it drives the two thigh support plates 5 to start rotating upward around the first rotation axis. During the upward rotation process, the two thigh support plates 5 can drive the patient's thighs to be lifted upward.

[0025] The upper ends of the two thigh support plates 5 are respectively slidably installed with extended calf plates 6 for supporting the patient's calves. The two extended calf plates 6 and the two thigh support plates 5 are limited by limiting parts. When the doctor needs the patient to lift both the thighs and calves, the extended calf plates 6 on the two thigh support plates 5 can be slid outwards. At this time, as the thigh support plates 5 are flipped upward, the two extended calf plates 6 supporting the patient's calves also flip upward, and the sliding connection between the extended calf plates 6 and the thigh support plates 5 can be limited by friction limiting.

[0026] The driving mechanism comprises a crank handle 2, a threaded rod 7, a second mounting plate 103, and a third mounting plate 104; The third mounting plates 104 are respectively fixedly mounted on both sides of the middle of the horizontal plate of the n-shaped bed plate 1, and the front sides of the two third mounting plates 104 are respectively mounted with second mounting plates 103, and the two second mounting plates 103 are respectively fixedly mounted on the two side walls of the first end of the horizontal plate of the n-shaped bed plate 1; The transverse plates of the n-type sliders 13 located on the same side are movably arranged between the second mounting plate 103 and the third mounting plate 104 located on the same side; The two n-shaped sliders 13 have threaded rods 7 installed in the transverse plates through which they are respectively threaded; The first ends of the two threaded rods 7 are rotatably mounted on the inner walls of the two third mounting plates 104 respectively; The first ends of the two threaded rods 7 are respectively rotated to pass through the side walls of the two second mounting plates 103 on which the crank handles 2 are installed. The crank handles 2 are operated to start rotating, and the rotation of the crank handles 2 drives the threaded rods 7 coaxially fixed therewith to start rotating. Since the ends of the threaded rods 7 are rotatably installed on the side walls of the third mounting plate 4, and the sliding trajectory of the n-type slider 13 has been determined, the threaded rods 7 can drive the n-type slider 13 to slide when they rotate.

[0027] The knee joint bending mechanism comprises a first connecting block 401 and a T-shaped sliding block 12; T-shaped slide grooves 101 are respectively provided on both sides of the top wall of the first end of the horizontal plate of the n-shaped bed plate 1, and the two T-shaped slide grooves 101 are respectively provided under the two thigh support plates 5; The two T-shaped slide grooves 101 are respectively slidably mounted with a horizontal plate having a T-shaped slide block 12; The upper ends of the vertical rods of the two T-shaped slide blocks 12 are respectively installed with first connecting frames; A first connection block 401 is respectively installed on the lower side of one end of the two calf support plates 4 away from the two thigh support plates 5, and the two first connection blocks 401 are respectively rotatably connected in the two first connection frames; The two calf expansion plates 6 are detachably arranged on the upper sides of the two calf support plates 4, Figure 2When the doctor needs the patient to flex his knees, the two extended calf plates 6 are retracted. At this time, as the two thigh support plates 5 are rotated and lifted upward, since the first connecting block 401 under the calf support plate 4 is rotatably connected with the T-shaped slider 12, the calf support plate 4 also begins to deflect upward as the thigh support plate 5 is lifted upward. The cooperation between the T-shaped slider 12 and the T-shaped slide groove 101 ensures the movement trajectory of the calf support plate 4. When the thigh support plate 5 is rotated upward to the extreme position, a certain angle is formed between the calf support plate 4 and the thigh support plate 5. At this time, the patient's calf originally placed on the calf support plate 4 will also droop downward under the influence of gravity and rest on the outer wall of the calf support plate 4 to achieve a knee flexion posture.

[0028] The upper limb rotation mechanism comprises a spur gear 9, a steering gear 901, a rack plate 8, a slide plate 14, a first rectangular slide block 15, and a second connecting rod 16; The two side walls of the n-shaped bed board 1 are respectively provided with first rectangular slide grooves 105, and slide plates 14 are respectively slidably installed in the two first rectangular slide grooves 105; Rack plates 8 are fixedly mounted on the outer walls of the two slide plates 14, respectively, and the front walls of the two rack plates 8 are in detachable contact with the rear walls of the two third mounting plates 104, respectively; The upper ends of the two rack plates 8 are respectively meshed with steering gears 901, and the two steering gears 901 are respectively rotatably mounted on the outer walls of the two first mounting plates 102 through the fourth rotating shafts, and the other ends of the two first rotating shafts are respectively rotatably penetrated through the side walls of the two first mounting plates 102 and fixed with spur gears 9, and the two spur gears 9 are respectively meshed with the two steering gears 901; The rear ends of the two slide plates 14 are respectively fixedly mounted with first rectangular sliders 15, and the outer walls of the two first rectangular sliders 15 are respectively fixedly mounted with second connecting frames; The first ends of the second connecting rods 16 are rotatably mounted in the two second connecting frames respectively; Fourth mounting plates 1002 are fixedly mounted on the middle ends of the outer walls of the two rotating plates 10; The second ends of the two second connecting rods 16 are respectively rotatably arranged at the lower ends of the two fourth mounting plates 1002, and the first rotating shafts on both sides rotate as the two thigh supporting plates 5 flip upward, and drive the spur gear 9 coaxially fixed therewith to start rotating during the rotation process, and the spur gear 9 drives the steering gear 9 meshing therewith to start rotating in the opposite direction through the rotation, and the rack plate 8 meshing with the steering gear 9 starts to slide, and the cooperation between the slide plate 14 and the first rectangular slide groove 105 can ensure the sliding track of the rack plate 8, and at the same time, the slide plate 14 drives the first rectangular slider 15 fixed thereto to start sliding as the rack plate 8 slides, and the first rectangular sliders 15 on both sides drive the second connecting rods 16 on both sides to start deflecting during the sliding process. Rotation, since the rotation centers of the two rotating plates 10 have been determined, the two second connecting rods 16 respectively drive the two rotating plates 10 to start reciprocating rotation around their respective rotation centers during the deflection process, and the patient's upper arms placed on the two upper arm support plates 22 can now reciprocate with the two rotating plates 10 with their lower arms. It should be noted that the rotation angle of the rotating plate 10 depends on the deflection angle of the second connecting rod 16, and the deflection angle of the second connecting rod 16 depends on the length of the travel distance of the rack plate 8, and the travel distance of the rack plate 8 can be changed by the outer diameter of the steering gear 901. The user can select steering gears 901 of different diameters as needed to control the rotation angle of the rotating plate 10.

[0029] The elbow joint bending mechanism comprises a second rectangular slider 17, a third rectangular slider 19, a connecting shaft 18, a third connecting rod 21, a fifth mounting plate 1101, and a third connecting frame 20; The two second connecting rods 16 are respectively provided with second rectangular sliding grooves 1601, and the second rectangular sliding blocks 17 are respectively slidably installed in the two second rectangular sliding grooves 1601; The upper ends of the two second rectangular sliding blocks 17 are respectively fixed with the first ends of the connecting shafts 18; The upper ends of the two rotating plates 10 are respectively provided with rectangular through grooves 1001, and third rectangular sliding blocks 19 are respectively slidably installed in the two rectangular through grooves 1001; The second ends of the two connecting shafts 18 are rotatably connected to the lower ends of the two third rectangular sliding blocks 19 respectively; The front sides of the two third rectangular sliding blocks 19 are respectively fixedly mounted with third connecting frames 20; The lower ends of the two forearm support plates 11 are respectively mounted with fifth mounting plates 1101; The first ends of the third connecting rods 21 are rotatably mounted on the two third connecting frames 20, and the second ends of the two third connecting rods 21 are rotatably connected to the side walls of the two fifth mounting plates 1101, respectively. The two third connecting rods 21 are both telescopic connecting rods that can be telescopically limited. Figure 4When the two second connecting rods 16 drive the two rotating plates 10 to rotate outward by deflection, the second rectangular slider 17 located in the second rectangular slide groove 1601 begins to slide to the right along the second rectangular slide groove 1601. While the second rectangular slider 17 slides to the right, the driving force for sliding to the right is transmitted to the third rectangular slider 19 through the connecting shaft 18, so that the third rectangular slider 19 also has the driving force for sliding to the right. Figure 5 When the third rectangular slider 19 slides to the right, it drives the third connecting frame 20 to start sliding to the right along the rectangular through groove 1001. In the process of sliding to the right, the third connecting frame 20 drives the third connecting rod 21 to start deflecting upward and supports the forearm support plate 11 connected to it upward during the upward deflection, thereby realizing the bending function of the elbow.

[0030] The upper ends of the inner walls of the two rotating plates 10 are respectively installed with fixed plates 25, and the two fixed plates 25 are respectively arranged on the outer sides of the inner walls of the two large arm support plates 22; The two ends of the fixed plate 25 near the first end of the n-type bed board 1 are arc structures for avoiding rigid contact between the patient's armpits and the equipment. When the rotating plate 10 is deflected, the arc structure at the end of the fixed plate 25 can fit the user's armpits to avoid rigid contact between the armpits and the equipment.

[0031] An expansion plate 23 is fixedly installed in the middle of the top wall of the vertical plate of the n-shaped bed plate 1 close to the rotating plate 10, and the upper ends of the two expansion plates 23 are respectively detachably installed with neck support blocks 24; The neck support blocks 24 are all made of flexible materials and are used to support the patient's neck.

[0032] The upper ends of the thigh support plate 5, the calf support plate 4, the upper arm support plate 22, the forearm support plate 11, and the extended calf plate 6 are all installed with flexible protective pads, whose function is to avoid rigid contact between the patient's skin and the equipment.

[0033] Implementation method of the present invention: The device is placed on a flat surface, and the patient lies on his back on the horizontal board of the n-shaped bed board 1, with his neck pressed against the neck support block 24, his upper arms placed on the upper arm support board 22, and his forearms placed on the forearm support board.

[0034] Embodiment 1: When the patient's thighs and calves need to be lifted, the doctor needs to first pull out the extended calf board 6 on the thigh support board 5, and let the patient's thighs be placed on the thigh support board 5 and the calves be placed on the extended calf board 6, and then select one side of the crank 2 to rotate according to the examination needs; As the crank 2 rotates, the thigh support plate 5 on the same side as the crank 2 is lifted upward, and the extended calf plate 6 is also lifted synchronously with the thigh support plate 5. The thigh and calf of the patient on it are lifted upward synchronously under the joint support of the thigh support plate 5 and the extended calf plate 6, and the patient's lower limbs can be examined at this time; As the thigh support plate 5 is lifted, the rotating plate 10 on the same side as the thigh support plate 5 also starts to rotate outward and drives the patient's upper arm to rotate outward. As the rotating plate 10 rotates, the forearm support plate 11 supporting the patient's forearm starts to rotate upward and drives the patient's forearm to bend upward, thereby achieving the bending effect of the elbow joint and avoiding artificial support. After checking the condition of one limb, the doctor can reversely rotate the crank 2 to restore the thigh support plate 5 and the rotating plate 10 to a horizontal state, and then operate the crank 2 on the other side to check the limb on the other side.

[0035] Embodiment 2 When the patient needs to bend his knees for a knee jerk reaction test, the doctor needs to first retract the extended calf board 6 and then put it on the thigh support board 5, let the patient's thigh be placed on the retracted extended calf board 6, and the calf be placed on the calf support board 4, and repeat the above operation. At this time, as the thigh support board 5 rotates upward, the calf support board 4 also begins to flip upward. The user's calf is affected by gravity and gradually flips downward and is finally supported by the calf support board 4. At this time, a certain angle can be formed between the user's thigh and calf, and the doctor can perform a knee jerk reaction test on the patient at this time.

[0036] The leg-lifting mechanism of the present invention can lift the patient's legs to avoid artificial support, and at the same time, the calf plate can be retracted or extended to choose whether to bend or straighten the patient's legs. The upper limb rotation mechanism of the present invention can rotate the patient's arms outward, and at the same time, the elbow joint bending mechanism can support the patient's forearms while rotating the arms outward, thereby achieving multi-angle support for the patient's limbs, thereby satisfying a variety of neurological testing postures.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
