Description

Technical Field

[0001] This invention relates to the technical field of vestibular function testing. More specifically, this invention relates to a vestibular function testing pillow. Background Technology

[0002] During vestibular function tests, in order to place the semicircular canals of the inner ear in the most sensitive vertical position, the patient usually needs to lie supine and have their head tilted up slightly with a special pillow.

[0003] However, due to individual differences in the anatomical structure of the head and neck among different patients, the ideal tilting angle varies from person to person, so the head support angle must be adjusted in a personalized manner.

[0004] The commonly used method is to attach several removable pads to the basic pillow using Velcro, and adjust the tilt angle by adding or removing the number of pads.

[0005] In practice, medical staff must manually align the edge of each pad precisely with the edge of the pillow to ensure a secure and smooth surface, preventing uneven pressure on the patient's head or discomfort due to misalignment. This alignment process is not only time-consuming and labor-intensive but also requires a high degree of precision. If alignment fails, the pasted pad must be removed and readjusted, resulting in repeated operations that affect examination efficiency. Summary of the Invention

[0006] To overcome the difficulty in aligning and pasting the pads in existing examination pillows, this invention provides a vestibular function examination pillow.

[0007] The technical solution is as follows: A vestibular function testing pillow includes a headrest with a triangular cross-section; it also includes a cushion 1, a cushion 2, a base plate, guide rail blocks, a long rod, a round rod 1, a connecting block, a spring, and a fixing assembly; cushion 1 is connected to the upper side of the headrest; cushion 2 is connected to the upper side of cushion 1; the base plate is fixed to the headrest; several guide rail blocks are fixed to the base plate; a long rod is connected to each guide rail block; several grooves 1 are formed on the headrest, cushion 1, and cushion 2, and the long rod passes through the corresponding grooves 1; a round rod 1 is slidably connected to each long rod; several round holes are formed on each guide rail block, and the end of the round rod 1 is inserted into the corresponding round hole; a connecting block is fixed to each round rod 1; a spring is fixed between each connecting block and the corresponding long rod; a fixing assembly is fixed between the headrest, cushion 1, and cushion 2; the fixing assembly is used to fix the headrest, cushion 1, and cushion 2.

[0008] Furthermore, the fixing components include Velcro 1 and Velcro 2; several Velcro 1s are fixedly attached to the headrest, cushion 1 and cushion 2; several Velcro 2s are fixedly attached to the headrest, cushion 1 and cushion 2, and the Velcro 2s are bonded to the corresponding Velcro 1s.

[0009] Furthermore, it also includes a storage component, which includes a second round rod and a slider; several second round rods are fixedly connected to each long rod; a slider is slidably connected to each guide block, and the second round rod and the corresponding slider are connected in a damped rotational connection.

[0010] Furthermore, the headrest, cushion one, and cushion two are each provided with several grooves two, and adjacent grooves two are aligned with each other, and groove two is connected to the corresponding groove one; the width of groove two is smaller than the width of groove one.

[0011] Furthermore, the headrest, cushion one, and cushion two are made of elastic material near the groove two.

[0012] Furthermore, the axis of the Velcro is perpendicular to the axis of the guide block.

[0013] Furthermore, a protective sleeve is provided on the surface of the long pole.

[0014] Furthermore, the surfaces of the headrest, cushion one, and cushion two are covered with antibacterial fabric.

[0015] Furthermore, the lower side of the base plate is made into a rough surface.

[0016] Furthermore, a chamfer is provided at one end of the round rod.

[0017] The present invention has the following advantages: First, by using two long rods in combination, the first pillow is positioned so that after the first pillow is attached to the head pillow, the edge of the first pillow can be completely aligned with the edge of the head pillow, thus ensuring the patient's comfort when resting on the head pillow and the first pillow. In addition, during the examination of the posterior semicircular canal, the long rods are also used to limit the rotation angle of the patient's head, so that the patient can rotate 45 degrees stably each time, which helps to improve the accuracy of the examination results. Second, under normal conditions, the long rod can be retracted into the inside of the headrest by cooperating with the second round rod and the slider, thus avoiding safety accidents caused by the long rod being erected. Third, a second groove is set at one end of the first groove, so that the long rod can move to the inside of the second groove to perform a limiting inspection operation on children with small heads. When adults with large heads rest on the first pillow, the discomfort of resting their heads on the area of ​​the second groove is greatly reduced because the second groove is much smaller than the first groove. Fourth, the axis of the first hook and loop fastener is set perpendicular to the axis of the guide rail block. The horizontal friction force is perpendicular to the first and second hook and loop fasteners, making it more difficult for the first and second hook and loop fasteners to be torn apart, thereby preventing the first cushion from being pulled off the headrest and improving structural stability.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: A vestibular function testing pillow, such as Figures 1-7 As shown, it includes a headrest 1; the headrest 1 has a triangular cross-section; it also includes a cushion 2, a cushion 3, a base plate 4, guide rail blocks 5, a long rod 6, a round rod 7, a connecting block 8, a spring 9, and a fixing assembly; the cushion 2 is connected to the upper side of the headrest 1; the cushion 3 is connected to the upper side of the cushion 2; the base plate 4 is fixed to the headrest 1, and the base plate 4 is made of alloy material; two guide rail blocks 5 are bolted to the base plate 4; each guide rail block 5 is connected to a long rod 6; two grooves 191 are opened on the headrest 1, cushion 2, and cushion 3, with a length of... Rod 6 passes through the corresponding groove 191; a round rod 7 is slidably connected to each long rod 6, and the round rod 7 is made of alloy material; several round holes 192 are opened on each guide block 5, and the end of the round rod 7 is inserted into the corresponding round hole 192; a connecting block 8 is fixedly connected to each round rod 7; a spring 9 is sleeved on the outside of each round rod 7, one end of the spring 9 is fixedly connected to the corresponding long rod 6, and the other end of the spring 9 is fixedly connected to the corresponding connecting block 8; a fixing component is fixedly connected between the headrest 1, the cushion 2, and the cushion 3.

[0022] The fixing components include Velcro 1 201 and Velcro 2 202; several Velcro 1 201s are fixedly attached to headrest 1, cushion 1 2 and cushion 2 3; several Velcro 2 202s are fixedly attached to headrest 1, cushion 1 2 and cushion 2 3, and the Velcro 2 202s are bonded to the corresponding Velcro 1 201s to fix cushion 1 2 to headrest 1.

[0023] First, headrest 1, pillow 2, and pillow 3 are separated from each other. During the examination, headrest 1 and its components are placed on the examination bed. The patient lies supine on the examination bed, with their head resting on the upper middle part of headrest 1 and their neck supported by the top of headrest 1, thus tilting their head upwards. This places the semicircular canals of the inner ear in their most sensitive vertical position. Then, the doctor rotates the patient's head 90 degrees left and right to examine the horizontal semicircular canals. Subsequently, the doctor rotates the patient's head 45 degrees left and right to examine the posterior semicircular canals. The doctor records the collected examination data. The data is synchronized in real time to the online diagnosis and treatment platform via a gateway. The platform then transmits the data instantly to remote expert terminals via the network. Online expert doctors conduct professional analysis and diagnosis based on this clinical information. After completing the diagnosis, the expert sends the diagnostic data, including the diagnostic opinion, condition assessment, and preliminary suggestions, back to the online platform and further pushes it to the original offline doctor's terminal device. The offline doctor combines their understanding of the patient's actual situation with the online expert's diagnostic conclusion to formulate more targeted medical advice and treatment plans for the patient. This closed-loop process effectively integrates high-quality online medical resources with offline medical service capabilities, realizing an intelligent diagnosis and treatment model that combines online and offline collaboration.

[0024] When adjusting the patient's tilt angle, the pillow 2 is manually moved directly above the headrest 1. Then, the pillow 2 is moved downwards, causing the two long rods 6 to insert into the two grooves 191 of the pillow 2. Since the width of the grooves 191 is equal to the thickness of the long rods 6, and the distance between the two grooves 191 is equal to the distance between the two long rods 6, the pillow 2 can be positioned in the front-back, left-right, and right-side directions using the two long rods 6, thus aligning the pillow 2 with the headrest 1. The pillow 2 is then moved downwards, causing the Velcro straps 202 on it to move downwards, adhering to the Velcro straps 201 on the headrest 1, thereby fixing the pillow 2 in place. On the upper side of headrest 1, at this point, the edge of cushion 2 is completely aligned with headrest 1. Then, the patient rests their head on the middle of headrest 1 and cushion 2, and the above operation is repeated for the examination. When performing a horizontal semicircular canal examination, the doctor controls the patient's side face to be in contact with cushion 2, which indicates that the head has turned 90 degrees. However, when performing a posterior semicircular canal examination, the doctor relies entirely on feeling to rotate the patient's head 45 degrees, which is difficult to ensure every time and is prone to excessive or insufficient rotation, thus affecting the test results. Therefore, after the patient rests their head on the middle of headrest 1 and cushion 2, the doctor moves the round rod 7 upward through connecting block 8 and stretches spring 9, making the round rod 7... The lower end of rod 7 moves away from the circular hole 192, causing the two long rods 6 to move in opposite directions. Then, using a measuring tool, the doctor turns the patient's head 45 degrees to the left, causing the left long rod 6 to move to the right until it contacts the patient's head. The left circular rod 7 then moves downwards and inserts into the corresponding circular hole 192 to secure it. Next, using the measuring tool, the doctor turns the patient's head 45 degrees to the right, causing the right long rod 6 to move to the left until it contacts the patient's head. The right circular rod 7 then moves downwards and inserts into the corresponding circular hole 192 to secure it. Finally, the doctor moves the patient's head... The device rotates back and forth, changing direction only after contacting the corresponding long rod 6 each time. This limits the angle of head rotation, ensuring a stable 45-degree rotation for the patient each time, thus improving the accuracy of subsequent examination results. During use, the two long rods 6 work together to position the pillow 2, ensuring its edge is perfectly aligned with the edge of the headrest 1 after it rests on the headrest 1. This ensures patient comfort when resting on the headrest 1 and pillow 2. Furthermore, during posterior semicircular canal examinations, the long rods 6 also limit the angle of head rotation, allowing for a stable 45-degree rotation each time, further improving the accuracy of examination results.

[0025] It also includes a storage component, which includes a round rod 203 and a slider 204; two round rods 203 are welded on each long rod 6; a slider 204 is slidably connected to each guide block 5, and the round rod 203 and the corresponding slider 204 are connected in a damped rotational connection.

[0026] In normal conditions, when a person instinctively leans against the examination pillow, their head may hit the erect long rod 6, posing a safety hazard. Therefore, after the inspection is completed, the long rod 6 is manually moved upwards via the connecting block 8, moving it away from the round hole 192. Then, the long rod 6 is moved to the left (or right) side of the headrest 1. The long rod 6 moves the round rod 203, which in turn moves the slider 204 to slide on the guide rail block 5, moving the slider 204 to the left (or right) side of the headrest 1. Then, the long rod 6 is manually moved upwards via the connecting block 8, pulling it out of the slider 204. Finally, the long rod 6 is manually rotated 90 degrees to the right (or left), moving it to the inside of the headrest 1 to complete the storage operation and prevent the erected long rod 6 from causing a safety accident. In use, under normal conditions, the long rod 6 can be stored inside the headrest 1 by the cooperation of the round rod 203 and the slider 204, preventing the erected long rod 6 from causing a safety accident.

[0027] Two grooves 193 are provided on each of the headrest 1, cushion 1 2 and cushion 2 3, and the adjacent grooves 193 are aligned with each other. The grooves 193 are connected to the corresponding grooves 191. The width of the grooves 193 is smaller than the width of the grooves 191.

[0028] The headrest 1, cushion 1 2 and cushion 2 3 are made of elastic material near the groove 2 193, so that the headrest 1, cushion 1 2 and cushion 2 3 near the groove 2 193 can quickly rebound after being squeezed by the long rod 6.

[0029] Due to the significant difference in head size between children and adults, the long rod 6 needs to be lengthened to accommodate children with smaller heads, making the end of the groove 191 closer to the center of the headrest 1. This allows the long rod 6 to slide closer to the center of the headrest 1 for restraint. However, with the groove 191 lengthened, adults using the examination pillow would experience discomfort as their heads would rest against the end of the groove 191. Therefore, a second groove 193 is provided at the end of the groove 191 to further support the headrest 2. During positioning, the initial position of the long rod 6 is at the end of the groove 191 on the headrest 1. The pillow 2 is manually moved to be directly above the headrest 1, and then moved downwards, causing the two long rods 6 to be inserted into the opposing ends of the two grooves 191 on the pillow 2. Since the width of the groove 191 is equal to the thickness of the long rod 6, and the distance between the opposing ends of the two grooves 191 is equal to the distance between the two long rods 6, the pillow 2 can be positioned using the two long rods 6, aligning it with the headrest 1. This is especially useful when examining children with small heads. The long rod 6 is moved towards the middle of the headrest 1, pressing the headrest 1 and the corresponding groove 193 of the cushion 2, thus moving the long rod 6 to the inside of the groove 193. The long rod 6 then limits the child's head position. When examining an adult with a large head, the long rod 6 is manually moved towards the end of the headrest 1, moving it from groove 193 to groove 191. The long rod 6 then limits the child's head position. After moving from groove 193 to groove 191, the corresponding grooves of the headrest 1 and the cushion 2... The positional rebound of groove 2 193 significantly reduces discomfort when adults with large heads rest their heads on cushion 1 2, as groove 2 193 is much smaller than groove 1 191. During use, groove 2 193 is located at the end of groove 1 191, allowing the long rod 6 to move to the inside of groove 2 193 for limiting and checking children with small heads. Similarly, when adults with large heads rest their heads on cushion 1 2, the discomfort is significantly reduced because groove 2 193 is much smaller than groove 1 191.

[0030] The axis of Velcro 201 is perpendicular to the axis of guide block 5.

[0031] When the long rod 6 moves into the groove 193, it compresses the area of ​​the cushion 2 corresponding to the groove 193 and applies horizontal friction to the cushion 2. There is a risk that the cushion 2 may be pulled off the headrest 1. Therefore, the axis of the Velcro 201 is set perpendicular to the axis of the guide block 5. The horizontal friction is perpendicular to the Velcro 201 and the Velcro 202, making it more difficult for the horizontal friction to tear the Velcro 201 and the Velcro 202 apart, thereby preventing the cushion 2 from being pulled off the headrest 1 and improving the structural stability.

[0032] Example 2, based on Example 1, such as Figure 7 As shown, the surface of the long rod 6 is equipped with a protective sleeve to cushion and protect the patient's head.

[0033] The surfaces of headrest 1, cushion 1 2 and cushion 2 3 are covered with antibacterial fabric to reduce bacterial growth.

[0034] The lower side of the base plate 4 is made into a rough surface to increase friction.

[0035] The end of the round rod 7 is chamfered, making it easier to insert the round rod 7 into the round hole 192.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
