Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation engineering and auxiliary technology, specifically relating to a support device for neurological examinations. Background Technology

[0002] Neurological examination support devices play an important role in rehabilitation engineering and assistive technology. By supporting the arm, the position of the patient's limbs can be precisely adjusted to ensure that the patient's posture meets the examination requirements during imaging examinations (such as CT, MRI) or neurological function assessments. This helps to obtain high-quality images and accurate diagnostic results.

[0003] While some existing internal medicine examination support devices have the function of fixing the patient's arm, they still have the drawback that the fixation process is relatively complicated. The complicated fixation process means that when medical staff switch between multiple patients, they need to spend more time adjusting the support device to ensure that it is correctly fixed to the patient's arm. This not only prolongs the patient's waiting time, but may also delay the entire diagnosis and treatment process, thereby reducing the overall efficiency of diagnosis and treatment.

[0021] In order to make the above-mentioned purpose, features and advantages of the utility model more apparent, easy to understand, the specific implementation of the utility model is described in detail below combined with the drawings of the specification.

[0022] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0023] Secondly, the "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0024] EMBODIMENT

[0025] REFERENCE Figures 1-4 For the embodiment of the utility model, the embodiment provides a neurology examination lifting device, which can realize the effect that the patient's arm is clamped and fixed automatically by the force of the patient's arm pressing down the supporting plate 202.

[0026] The lifting mechanism 100 comprises a fixed frame 101, a servo motor 102 mounted on the top of the fixed frame 101, a connecting column 103 fixedly connected to the output end of the servo motor 102 through a shaft coupling, a one-way threaded rod 104 fixedly connected to the through end of the connecting column 103, and a first internal threaded block 105 threadedly connected to the outer surface of the one-way threaded rod 104.

[0027] It should be noted that when the servo motor 102 rotates, the connecting column 103 and the one-way threaded rod 104 can be driven to rotate synchronously, and the first internal threaded block 105 drives the fixed box 201 to move linearly through the limiting of the fixed frame 101 to the first internal threaded block 105.

[0028] The limiting mechanism 200 comprises a fixed box 201 fixedly connected to the outer surface of the first internal threaded block 105, a supporting plate 202 arranged outside the fixed box 201, a rack plate 203 fixedly mounted on the outer surface of the supporting plate 202, a gear 204 engaged with the outer surface of the rack plate 203, a bidirectional threaded rod 205 fixedly connected to the inner surface of the gear 204, second internal threaded blocks 206 threadedly connected to the two side surfaces of the bidirectional threaded rod 205 respectively, a connecting rod 207 fixedly connected to the outer surface of the second internal threaded block 206, a limiting plate 208 fixedly mounted on the through end of the connecting rod 207 and cooperated with the fixed box 201, a first spring 209 fixedly mounted on the inner wall of the fixed box 201 and cooperated with the rack plate 203, and a positioning assembly 210 capable of preventing the bidirectional threaded rod 205 from rotating reversely in the inspection process.

[0029] It should be noted that the supporting plate 202 is used to support the arm of the patient, and when the arm of the patient is placed above the supporting plate 202, the supporting plate 202 and the rack plate 203 are driven to press downward, so that the rack plate 203 drives the gear 204 and the bidirectional threaded rod 205 to rotate at the same time, and a pressure is applied to the first spring 209, and the two connecting rods 207 are limited by the fixed box 201, so that the two connecting rods 207 limit the two second internal threaded blocks 206 respectively, so that the two second internal threaded blocks 206 drive the two connecting rods 207 and the limiting plate 208 to move towards each other in the direction close to the supporting plate 202, so as to realize the effect that the limiting plate 208 is automatically clamped and fixed to the arm of the patient through the force of the patient's arm pressing the supporting plate 202.

[0030] Specifically, bearings are mounted at the connection between the connecting column 103 and the fixed frame 101 for cooperation in rotation, and the outer end surface of the one-way threaded rod 104 is fixedly mounted on the inner wall of the fixed frame 101 through bearings.

[0031] Further, the rack plate 203 extends into the inside of the fixed box 201, the gear 204 is located in the inner cavity of the fixed box 201, and the bidirectional threaded rod 205 is fixedly mounted on the inner wall of the fixed box 201 through bearings.

[0032] Preferably, the outer surface of the connecting rod 207 is in sliding contact with the inner surface of the fixed box 201, and the outer end surface of the first spring 209 is fixedly connected with the outer surface of the rack plate 203.

[0033] It should be noted that the positioning assembly 210 includes a support column 210a fixedly connected to the outer surface of the fixed box 201, and a pawl 210b rotatably sleeved on the outer surface of the supporting plate 202.

[0034] Further, the positioning assembly 210 further includes a ratchet wheel 210c engaged with the outer surface of the pawl 210b, a support rod 210d fixedly connected to the inner surface of the ratchet wheel 210c and matched with the bidirectional threaded rod 205, and a second spring 210e fixedly installed on the outer surface of the fixed box 201 and matched with the pawl 210b.

[0035] Specifically, the penetrating section of the support rod 210d is fixedly connected with the outer end surface of the bidirectional threaded rod 205, and a bearing sleeve matched with rotation is installed at the connection between the support rod 210d and the fixed box 201.

[0036] Further, through the cooperation of the bidirectional threaded rod 205 and the support rod 210d, the ratchet wheel 210c is driven to rotate synchronously, so that the ratchet wheel 210c extrudes the pawl 210b and the second spring 210e, and then the pawl 210b limits the ratchet wheel 210c, thereby preventing the bidirectional threaded rod 205 from rotating reversely due to the accidental lifting of the patient's arm, and causing the limiting plate 208 to be released from the limiting effect.

[0037] In use, the patient's arm is placed on the supporting plate 202, and the natural descent of the arm drives the supporting plate 202 and the rack plate 203 to press downward, so that the rack plate 203 drives the gear 204 and the bidirectional threaded rod 205 to rotate while providing a pressure to the first spring 209. Through the limiting of the fixed box 201 on the two connecting rods 207, the two connecting rods 207 limit the two second internal threaded blocks 206 respectively, so that the two second internal threaded blocks 206 drive the two connecting rods 207 and the limiting plate 208 respectively to move towards the supporting plate 202, thereby realizing the effect that the force of the patient's arm pressing downward on the supporting plate 202 drives the limiting plate 208 to automatically clamp and fix the patient's arm. Through the cooperation of the bidirectional threaded rod 205 and the support rod 210d, the ratchet wheel 210c is driven to rotate synchronously, so that the ratchet wheel 210c extrudes the pawl 210b and the second spring 210e, and then the pawl 210b limits the ratchet wheel 210c, thereby preventing the bidirectional threaded rod 205 from rotating reversely due to the accidental lifting of the patient's arm, and causing the limiting plate 208 to be released from the limiting effect.

[0038] When the patient's arm needs to be lifted: the servo motor 102 drives the connecting column 103 to rotate synchronously with the one-way threaded rod 104, the first inner threaded block 105 is limited by the fixed frame 101, so that the first inner threaded block 105 drives the fixed box 201 to move linearly, and then each component in the limiting mechanism 200 is driven by the fixed box 201 to move synchronously with the patient's arm to the appropriate position;

[0039] When the limiting plate 208 needs to be released from limiting the patient's arm: move the pawl 210b to a position where it is out of engagement with the ratchet wheel 210c, slightly lift the patient's arm, move it to a position where it is out of contact with the supporting plate 202, reset the rack plate 203 and the gear 204 through the reaction force of the first spring 209, make the gear 204 drive the bidirectional threaded rod 205 to rotate in the opposite direction, and then make the two connecting rods 207 and the limiting plate 208 move towards each other in the direction away from the supporting plate 202 to release the limiting plate 208 from limiting the patient's arm.

[0040] In summary, through the cooperation between each component in the limiting mechanism 200, the patient's arm can drive the limiting plate 208 to automatically clamp and fix the patient's arm through the force of pressing down the supporting plate 202, and the position of the limiting plate 208 can be automatically locked by the positioning assembly 210, so that when switching between multiple patients, the operation steps and time can be greatly reduced, the waiting time of the patients can be shortened, and the overall diagnosis and treatment efficiency can be improved.
