Description

Technical Field

[0001] This utility model relates to the field of ophthalmic examination technology, specifically to an ophthalmic examination lying position assist device. Background Technology

[0002] An ophthalmic examination positioning aid is an assistive device specifically designed for ophthalmic examinations to improve patient comfort and convenience. It primarily supports and stabilizes the patient's head, allowing doctors to perform more accurate examinations.

[0003] A search revealed that patent CN202210840544.3 discloses a multifunctional rigid-flexible coupling ophthalmic supine examination auxiliary device. Although the device combines Hooke's law and electromagnetic principles to couple and clamp the patient's head during use, solving the contradictory technical problem of both fixing and not fixing the patient's head, the device can only flexibly fix the patient's head during use and cannot allow the patient's head to be adjusted at the corresponding angle according to the doctor's examination requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a supine position assistive device for ophthalmic examinations, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An ophthalmic examination lying position assist device includes a control box, one end of which is equipped with a headrest, and the other end of the control box opposite to the headrest is equipped with a pad, on which an air cushion is laid;

[0007] An inflatable neck pillow is placed on the control box. A rotating shaft is rotatably installed inside the control box. A worm gear is provided on the rotating shaft. A connecting block is provided at the bottom of the head pillow. A connecting shaft is inserted into the connecting block. A worm wheel is provided at one end of the connecting shaft inside the control box. The rotating shaft meshes with the worm wheel of the connecting shaft through the worm gear, thereby driving the connecting shaft to rotate, and thus driving the head pillow connected to the connecting shaft to deflect.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the headrest is U-shaped and has a slot. An airbag is installed on the headrest through the slot, and the airbag flexibly clamps and fixes the patient's head.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The U-shaped headrest design conforms to the physiological curve of the neck, providing excellent neck support for patients. This design helps reduce pressure on the neck during examinations, minimizing cervical fatigue and discomfort. The airbag, installed via a locking mechanism, provides flexible clamping and fixation for the patient's head. This flexible fixation method is more comfortable than rigid fixation, reducing pressure and discomfort on the head during examinations.

[0012] Furthermore, a bracket is welded to the outer surface of the control box below the headrest, a support rod is provided on the bracket, and a roller is rotatably mounted on the bracket via the support rod, and the connecting block is further supported by the roller.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The bracket and the outer surface of the control box are connected by welding. This connection method offers high strength and stability, capable of withstanding significant forces and pressures. The welded bracket not only provides robust support but also ensures the stability and safety of the entire auxiliary device structure. Support rods are mounted on the bracket and connected to the connecting block via rotating rollers. This design ensures stable support for the headrest during deflection, preventing wobbling or instability caused by deflection.

[0015] Furthermore, a support rib is provided between the lower surface of the bracket and the control box, which assists in supporting the bracket.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The presence of supporting ribs significantly enhances the connection strength between the support frame and the control box, making the entire assistive device structure more stable. This design effectively prevents deformation or displacement of the support frame under stress, thus ensuring patient safety and comfort during examinations. As an additional support structure, the supporting ribs can share the weight borne by the support frame. This not only improves the overall load-bearing capacity of the assistive device but also extends its service life. During ophthalmic examinations, patients may need to maintain a lying position for extended periods; the supporting rib design ensures that the assistive device will not be damaged or deformed during this process.

[0018] Furthermore, a handwheel is provided at one end of the rotating shaft located outside the control box, and the rotating shaft is driven to rotate by the handwheel.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The handwheel design allows users to control the rotation of the shaft directly by hand, without the need for complicated procedures or tools. This intuitive operation reduces the learning curve, enabling users to quickly learn and make accurate adjustments. Handwheels typically have a large diameter and a comfortable grip, making them easier to use. This is especially beneficial in ophthalmological examinations where frequent adjustments to the shaft's position or angle are required, significantly reducing the user's workload.

[0021] Furthermore, the size of the air cushion and inflatable neck pillow is adapted to the size of the pad and control box, respectively, and the patient lies on the pad and control box using the air cushion and inflatable neck pillow.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The air cushion and inflatable neck pillow are sized to fit the pad and control box, respectively. This design ensures that patients receive comprehensive and comfortable support during use, preventing discomfort due to size mismatch. The introduction of the air cushion increases lying comfort; its softness and adjustability (though not explicitly mentioned, these are common characteristics of air cushions) provide better support and comfort, reducing fatigue from prolonged lying down. Maintaining a supine position can be challenging for patients with kyphosis, ankylosing spondylitis, and cervical spondylosis. With the assistance of the air cushion and inflatable neck pillow, these patients can more easily maintain a supine position, resulting in a better experience and outcome during ophthalmological examinations. The design of the air cushion and inflatable neck pillow allows for personalized adjustments based on the patient's specific needs. For example, the inflation level of the air cushion can be adjusted according to the patient's comfort and needs, and the position or height of the inflatable neck pillow can be adjusted as needed to provide optimal support.

[0024] This invention provides a supine positioning aid for ophthalmic examinations. It has the following beneficial effects:

[0025] The headrest has a slot and uses an airbag to flexibly hold and fix the patient's head. This method is more comfortable than traditional rigid fixation and can reduce patient discomfort during the examination. The control box is padded to increase patient comfort while lying down and avoid the pressure and discomfort caused by prolonged lying down.

[0026] The headrest's tilt is adjusted by rotating a shaft via a handwheel, which in turn engages a worm gear and a worm wheel. This design allows doctors to easily adjust the patient's head angle according to examination needs, improving the flexibility and accuracy of the examination. The support frame is connected to the control box via support ribs, increasing the stability of the support structure. Additionally, rollers are rotatably mounted on the support frame via support rods, further enhancing the stability and reliability of the headrest adjustment. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0037] Example 1

[0038] An ophthalmic examination positioning aid includes a control box 2. A headrest 1, U-shaped and with a slot 101, is mounted on one end of the control box 2. An airbag 102 is mounted on the headrest 1 via the slot 101, flexibly clamping and fixing the patient's head. The U-shaped headrest 1 is designed according to ergonomic principles, precisely conforming to the natural physiological curve of the neck, providing support that matches the patient's neck shape. This design strategy significantly reduces the stress on the neck during the examination process, effectively alleviating cervical fatigue and discomfort. Meanwhile, the airbag 102 achieves flexible clamping and fixation through the limiting mechanism of the slot 101. Compared with the rigid fixation method, this flexible fixation strategy is more comfortable and can significantly reduce the pressure effect and discomfort on the head during the examination. The control box 2 is equipped with a pad 3 at the end opposite to the headrest 1. An air cushion 4 is laid on the pad 3. The size of the air cushion 4 and the inflatable neck pillow 5 are adapted to the size of the pad 3 and the control box 2, respectively. The patient lies on the pad 3 and the control box 2 with the air cushion 4 and the inflatable neck pillow 5. For patients with kyphosis or ankylosing spondylitis and cervical spondylosis, it can be used to support the back to help the patient maintain a supine position. The size of the air cushion 4 and the inflatable neck pillow 5 are adapted to the size of the pad 3 and the control box 2, respectively. This design ensures that the patient can get full and comfortable support when using it and will not feel uncomfortable due to size mismatch. The introduction of air cushion 4 increases lying comfort. The softness and adjustability of air cushion 4 (although not explicitly mentioned, this is a common characteristic) provide better support and comfort for patients, reducing fatigue from prolonged lying down. Maintaining a supine position can be challenging for patients with kyphosis, ankylosing spondylitis, and cervical spondylosis. With the assistance of air cushion 4 and inflatable neck pillow 5, these patients can more easily maintain a supine position, resulting in a better experience and outcome during ophthalmological examinations. The design of air cushion 4 and inflatable neck pillow 5 allows for personalized adjustments based on the patient's specific needs. For example, the inflation level of air cushion 4 can be adjusted according to the patient's comfort and needs, and the position or height of inflatable neck pillow 5 can also be adjusted as needed to provide optimal support.

[0039] Example 2

[0040] To facilitate adjustment of the patient's head angle, for example, such as Figures 1 to 4As shown, the invention also includes: a rotating shaft 205 rotatably mounted inside the control box 2; a handwheel 207 is provided at one end of the rotating shaft 205 located on the outside of the control box 2; the handwheel 207 drives the rotating shaft 205 to rotate; the handwheel 207 is designed with an intuitive and easy-to-use operating concept, allowing users to directly control the rotation of the rotating shaft 205 by manual rotation, without complicated operating steps or auxiliary tools. This design reduces the difficulty of operation and improves the user's operating efficiency and accuracy. The handwheel 207 typically has a large diameter and an ergonomic grip design, making it easier for users to rotate and reducing fatigue during operation. Especially in ophthalmological examinations where the position or angle of the rotating shaft 205 needs frequent adjustment, the design of the handwheel 207 significantly reduces the user's operational burden and improves examination efficiency. The rotating shaft 205 is equipped with a worm gear 208, and the bottom of the headrest 1 is equipped with a connecting block 203. A connecting shaft 202 is inserted into the connecting block 203. One end of the connecting shaft 202 located inside the control box 2 is equipped with a worm wheel 209. The rotating shaft 205 meshes with the worm wheel 209 of the connecting shaft 202 through the worm gear 208, thereby driving the connecting shaft 202 to rotate, which in turn drives the headrest 1 connected to the connecting shaft 202 to deflect. A bracket 204 is welded to the outer surface of the control box 2 below the headrest 1. A support rib 206 is provided between the lower surface of the bracket 204 and the control box 2. The support rib 206 assists in supporting the bracket 204. The design of the support rib 206 significantly enhances the connection strength between the bracket 204 and the control box 2, further improving the structural stability of the entire auxiliary device. This design effectively prevents deformation and displacement of the support 204 under stress, ensuring patient safety and comfort during examinations. Simultaneously, the supporting rib 206, as an additional load-bearing structure, can share the load borne by the support 204, improving the overall load-bearing capacity and service life of the assistive device. During ophthalmic examinations, patients may need to maintain a lying position for extended periods. The design of the supporting rib 206 ensures that the assistive device will not be damaged or deformed during this process, guaranteeing the smooth conduct of the examination. The support 204 is equipped with a support rod 210, and a roller 201 is rotatably mounted on the support 204 via the support rod 210. The connecting block 203 is further supported by the roller 201. The support 204 is connected to the outer surface of the control box 2 using a high-strength welding process, ensuring the stability and durability of the connection. This welding method can withstand significant mechanical loads, providing solid structural support for the entire assistive device. Welding the support 204 not only improves the overall support strength but also ensures the stability and safety of the assistive device structure, effectively preventing deformation and displacement under stress. In addition, the support rod 210 and the bracket 204 are connected by the rotating roller 201 and the connecting block 203, which ensures the stability of the headrest 1 during the deflection process and avoids shaking and instability.

[0041] Working principle:

[0042] The patient lies on the control box 2 and the pad 3, with their head resting on the headrest 1. By adjusting the position and thickness of the padding, as well as the angle of the headrest 1, the patient can achieve an optimal lying position. The headrest 1 features a U-shaped design that conforms to the shape of the human head, providing comfortable support. The design of the slot 101 and the airbag 102 allows the headrest 1 to flexibly hold and fix the patient's head, reducing discomfort. The control box 2 is padded, increasing the patient's comfort while lying down. The material and thickness of the padding can be selected as needed to meet the needs of different patients.

[0043] An air cushion 4 is placed on the pad 3. The softness and adjustability of the air cushion 4 provide good support and comfort for the patient. The neck pillow is the same size as the control box 2 and can be placed under the patient's back to help the patient maintain a supine position.

[0044] The doctor or operator adjusts the deflection angle of the headrest 1 by turning handwheel 207 according to the examination requirements. The deflection angle of the headrest 1 can be determined by observing the meshing of the worm gear 208 and worm wheel 209, as well as the rotation angle of the shaft 205. When the doctor or operator turns handwheel 207, handwheel 207 drives the shaft 205 to rotate. The worm gear 208 mounted on the shaft 205 rotates accordingly, meshing with the worm wheel 209 at one end of the connecting shaft 202. The meshing relationship between the worm gear 208 and worm wheel 209 allows the worm wheel 209 to drive the connecting shaft 202 to rotate. The connecting shaft 202 is connected to the headrest 1 through connecting block 203, so when the connecting shaft 202 rotates, it will cause the headrest 1 to deflect. The deflection angle of the headrest 1 depends on the degree of meshing between the worm gear 208 and worm wheel 209, as well as the rotation angle of the shaft 205. The bracket 204 is connected to the control box 2 through support rib plate 206, providing a stable support structure. The support rod 210 and roller 201 mounted on the bracket 204 further enhance the stability of the headrest 1 during the deflection process.

[0045] After adjusting the headrest 1 to the correct angle, the doctor can proceed with the eye examination. Because both the headrest 1 and the cushion are ergonomically designed, the patient will feel more comfortable and relaxed during the examination.
