Description

Technical Field

[0001] This invention relates to a fixation device, and more particularly to a head fixation device for ophthalmic eye washing. Background Technology

[0002] Ophthalmology is the study of diseases that occur in the visual system, including the eyeball and related tissues. In the diagnosis and treatment of eye-related diseases, it is often necessary to help patients wash their eyes in order to facilitate subsequent examinations and procedures. During the eye washing process, the patient's head needs to be fixed to prevent damage to the patient's eyes.

[0003] Existing technologies for securing the user's head typically use movable silicone pads to hold the upper and left / right sides of the user's head in place before eye washing. However, this type of device has several drawbacks. First, waste fluid generated after eye washing may spill onto the user's face, making collection inconvenient. Second, the components used for collecting waste fluid may move directly onto the user's eyes, potentially causing eye damage. Third, the components must be directly facing the user's eyes, and the fixed components cannot be adjusted in distance. Finally, during waste fluid collection, the components pressing against the user's eyes may move erratically due to external factors, causing discomfort to the user's eyes.

[0004] Therefore, it is necessary to design an ophthalmic head-fixing device that is easy to operate, fully secures the user's head, facilitates waste liquid collection, protects the user's eyes, allows for adjustment of components according to eye distance, and facilitates the fixation of the buffer pad to reduce the impact on the user's eyes. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a simple and comprehensive head-fixing device for ophthalmic eye washing that secures the user's head, facilitates waste liquid collection, protects the user's eyes, allows for adjustment of components based on eye distance, and facilitates the fixing of a buffer pad to reduce the impact on the user's eyes.

[0006] The objective of this invention can be achieved using the following technical solutions:

[0009] Furthermore, the upper fixing component includes: a second support rod, which is slidably connected to one side of the upper part of the support frame, and has multiple evenly spaced slots on the lower outer side of the second support rod; a third silicone pad, which is connected to the inner side of the upper part of the second support rod; a first rack, which is symmetrically slidably connected to one side of the upper part of the support frame, and one side of the first rack is connected to the first support rod on the same side; a first gear, which is symmetrically rotatably connected to one side of the upper part of the support frame, and the first gear meshes with the first rack on the same side; a turntable, which is connected to one side of the first gear drive shaft; push rods, which are slidably connected to the outer side of the turntable at even intervals, and the push rods cooperate with the second support rod; and a first spring, which is connected between the push rod and the turntable, and the first spring is sleeved on the push rod.

[0010] Furthermore, it also includes a locking assembly, which includes: a locking block, which is symmetrically and slidably connected to one side of the upper part of the support frame, and the locking block cooperates with the second support rod; a first connecting rod, which is connected to both sides of the upper part of the locking block; a second connecting rod, which is connected to both sides of the upper part of the locking block, and the second connecting rod is located outside the first connecting rod; and a fixing rod, which is symmetrically connected to the outside of the push rod, and the fixing rod cooperates with the first and second connecting rods.

[0011] Furthermore, it also includes a waste liquid collection assembly, which includes: a third support rod, which is slidably connected to one side of the upper part of the support frame; a support plate, which is symmetrically slidably connected to one side of the upper part of the third support rod; a first guide rod, which is symmetrically connected to one side of the inside of the support plate; a baffle, which is slidably connected between the first guide rods; a second spring, which is symmetrically connected between the baffle and the support plate, and the second spring is sleeved on the first guide rod; a collection frame, which is connected to one side of the upper part of the base; a cover plate, which covers the upper part of the collection frame; and pipes, which are connected between one side of the support plate and the collection frame, and the pipes cooperate with the baffles.

[0012] Furthermore, it also includes a buffer adjustment assembly, which includes: a second guide rod, which is symmetrically and slidably connected to both sides of the upper part of the support plate; a third spring, which is connected between the second guide rod and the support plate; a buffer pad, which is connected between the lower sides of the second guide rod and is located on the outside of the support plate; a second rack, which is slidably connected to both sides of the upper part of the third support rod and is connected to the support plate on the same side on the outside; a rotating rod, which is rotatably connected to the middle of one side of the upper part of the third support rod; and a second gear, which is connected to one side of the rotating rod and meshes with the second rack.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0030] Example 1

[0031] like Figures 1 to 7 As shown, this embodiment discloses a head fixing device for ophthalmic eye washing, including a base 1, a support frame 2, a first silicone pad 3, two side fixing components 4, an upper fixing component 5, and a locking component 6. The support frame 2 is connected to the upper rear side of the base 1. Four first silicone pads 3 are evenly connected to the upper part of the support frame 2. Two side fixing components 4 are provided on the upper left and right sides of the support frame 2. An upper fixing component 5 is provided on the upper rear side of the support frame 2. A locking component 6 is provided between the upper rear side of the support frame 2 and the upper fixing component 5.

[0032] The two-sided fixing components 4 include a lead screw 41, a throttle 42, a first support rod 43, and a second silicone pad 44. The lead screw 41 is rotatably connected to the middle of the support frame 2. The first support rod 43 is slidably connected to both sides of the lead screw 41 via threads. The first support rod 43 is slidably connected to the support frame 2. The second silicone pad 44 is connected to the inner side of the upper part of the first support rod 43. The throttle 42 is connected to the right side of the lead screw 41.

[0033] The upper fixing component 5 includes a second support rod 51, a third silicone pad 52, a first rack 53, a first gear 54, a turntable 55, a push rod 56, and a first spring 57. The second support rod 51 is slidably connected to the upper rear side of the support frame 2. Multiple slots are evenly spaced on the lower outer side of the second support rod 51. The third silicone pad 52 is connected to the upper inner side of the second support rod 51. The first rack 53 is symmetrically slidably connected to the upper rear side of the support frame 2. The front part of the first rack 53... The inner side is connected to the first support rod 43 on the same side. The upper rear side of the support frame 2 is symmetrically connected to the first gear 54 in a rotating manner. The first gear 54 meshes with the first rack 53 on the same side. The rear side of the transmission shaft of the first gear 54 is connected to the turntable 55. Six push rods 56 are evenly slidably connected to the outer side of the turntable 55. The push rods 56 cooperate with the second support rod 51. The push rods 56 and the turntable 55 are connected to the first spring 57. The first spring 57 is sleeved on the push rod 56.

[0034] It also includes a locking component 6, which includes a locking block 61, a first connecting rod 62, a second connecting rod 63, and a fixing rod 64. The locking block 61 is symmetrically and slidably connected to the upper rear side of the support frame 2. The locking block 61 cooperates with the second support rod 51. The first connecting rod 62 and the second connecting rod 63 are connected to the front and rear sides of the upper part of the locking block 61. The second connecting rod 63 is located outside the first connecting rod 62. The fixing rod 64 is symmetrically connected to the outer side of the push rod 56. The fixing rod 64 cooperates with the first connecting rod 62 and the second connecting rod 63.

[0035] When the device is needed to secure the user's head, the user first lies down and places their head on the first silicone pad 3. The user then pushes the handle 42 to rotate, causing the lead screw 41 to rotate. This moves the first support rod 43 and the second silicone pad 44 inwards, clamping and securing the user's head on both sides. Simultaneously, the first rack 53 moves inwards, causing the first gear 54 to rotate. This, in turn, rotates the turntable 55, push rod 56, and fixing rod 64. Once the push rod 56 rotates until it engages in the slot of the second support rod 51, the rotation of the push rod 56 will then drive the second... The support rod 51 moves downward, causing the third silicone pad 52 to move downward. Simultaneously, the fixing rod 64 smoothly passes through the gap between the first connecting rod 62 and the second connecting rod 63. After the third silicone pad 52 presses against the user's head, the second support rod 51 can no longer move, while the turntable 55, push rod 56, and fixing rod 64 continue to rotate. At this point, the push rod 56 rotates until it contacts the second support rod 51 and is pushed outward. The first spring 57 is compressed, causing the fixing rod 64 to move outward, thereby pushing the first connecting rod 62, the second connecting rod 63, and the locking block 61 outward. Lateral movement causes the locking block 61 to clamp and fix the second support rod 51. After the push rod 56 rotates away from the second support rod 51, under the action of the first spring 57, it pushes the push rod 56 and the fixing rod 64 inwards, returning to their original state. This process repeats until the second silicone pad 44 clamps and fixes the user's head. Then, the push rod 56 and the fixing rod 64 stop rotating. After the user finishes washing their eyes, they reverse the rotation of the handle 42, causing the lead screw 41 to rotate in the opposite direction. This causes the first support rod 43 and the first silicone pad 3 to move outwards, releasing the user's head from both sides. Simultaneously, the first... The rack 53 moves outward, causing the first gear 54 to rotate in the opposite direction, which in turn causes the turntable 55, push rod 56, and fixing rod 64 to rotate in the opposite direction. After the fixing rod 64 rotates to contact the first connecting rod 62 and the second connecting rod 63, it will push the first connecting rod 62, the second connecting rod 63, and the locking block 61 to move inward, releasing the second support rod 51. At this time, the push rod 56 and the fixing rod 64 continue to rotate, and the push rod 56 will drive the second support rod 51 and the third silicone pad 52 to move upward, thus releasing the user's head and restoring it to its original state, achieving the effect of completely fixing the user's head with simple operation.

[0036] Example 2

[0037] like Figure 1 , Figure 2 , Figures 8-12As shown, in some embodiments, a waste liquid collection assembly 7 is also included. The waste liquid collection assembly 7 includes a third support rod 71, a support plate 72, a first guide rod 73, a baffle 74, a second spring 75, a pipe 76, a collection frame 77, and a cover plate 78. The third support rod 71 is slidably connected to the upper rear side of the support frame 2. The third support rod 71 is located in front of the second support rod 51. The support plate 72 is symmetrically slidably connected to the upper front side of the third support rod 71. The first guide rod 73 is symmetrically connected to the inner front side of the support plate 72. The baffle 74 is slidably connected between the first guide rods 73. The second spring 75 is symmetrically connected between the baffle 74 and the support plate 72. The second spring 75 is sleeved on the first guide rod 73. The collection frame 77 is connected to the upper front side of the base 1. The collection frame 77 is covered with a cover plate 78. The pipe 76 is connected between the front side of the support plate 72 and the collection frame 77. The pipe 76 and the baffle 74 cooperate with each other.

[0038] It also includes a buffer adjustment assembly 8, which includes a second guide rod 81, a buffer pad 82, a third spring 83, a second rack 84, a second gear 85, and a rotating rod 86. The second guide rod 81 is symmetrically and slidably connected to the front and rear sides of the upper part of the support plate 72. The second guide rod 81 is connected to the support plate 72 by the third spring 83. The buffer pad 82 is connected to the lower side of the second guide rod 81 and is located on the outside of the support plate 72. The second rack 84 is slidably connected to the left and right sides of the upper part of the third support rod 71. The outer side of the second rack 84 is connected to the support plate 72 on the same side. The rotating rod 86 is rotatably connected to the middle of the front side of the upper part of the third support rod 71. The second gear 85 is connected to the rear side of the rotating rod 86. The second gear 85 meshes with the second rack 84.

[0039] After the user's head is secured, pushing the third support rod 71 downwards moves the support plate 72, baffle 74, buffer pad 82, rotating rod 86, second gear 85, and second rack 84 downwards. Once the buffer pad 82 reaches the eye level, it stops moving, while the third support rod 71 and support plate 72 continue downwards, compressing the third spring 83. At this point, the third support rod 71 is released, and the third spring 83 pushes it and the support plate 72 upwards, achieving a cushioning effect. Then, based on the user's eye distance, rotating rod 86 rotates, causing the second gear 85 to rotate, which in turn moves the second rack 84, further moving the support plate 72 and buffer pad 82 until they are directly facing the user's eyes. After eye washing, excess waste liquid flows into the inside of the support plate 72. At this time, push the baffle 74 to move upward, compress the second spring 75, and no longer block the pipe 76, allowing the waste liquid to flow into the collection frame 77 through the pipe 76. After the waste liquid has completely flowed out, release the baffle 74. Under the action of the second spring 75, push the baffle 74 to move downward, returning to its original state. Open the cover 78 to pour out and clean up all the waste liquid in the collection frame 77. Then close the cover 78 and push the third support rod 71 to move upward. The support plate, baffle 74, buffer pad 82, rotating rod 86, second gear 85, and second rack 84 move upward, moving the support plate 72 and buffer pad 82 away from the user's eyes, returning to their original state. This achieves the effects of conveniently collecting the waste liquid generated after eye washing, protecting the user's eyes, and allowing the components to be adjusted according to eye distance.

[0040] It also includes a locking assembly 9, which includes a pull rod 91, a friction block 92 and a fourth spring 93. The pull rod 91 is slidably connected between the left and right sides of the upper part of the support frame 2. The pull rod 91 and the support frame 2 are symmetrically connected to the fourth spring 93. The fourth spring 93 is sleeved on the pull rod 91. The friction block 92 is symmetrically connected to the left and right sides of the rear side of the pull rod 91. The friction block 92 cooperates with the third support rod 71.

[0041] Pulling lever 91 forward stretches the fourth spring 93, causing friction block 92 to move forward away from the third support rod 71. This allows the third support rod 71 to move downward, eventually moving the support plate 72 and buffer pad 82 to the user's eyes. Releasing lever 91 allows the fourth spring 93 to push lever 91 and friction block 92 backward, fixing the third support rod 71 in place, thus securing the support plate 72 and buffer pad 82. After waste liquid collection, repeat the above operation. With friction block 92 moving away from the third support rod 71, it pushes the third support rod 71 upward, moving the support plate 72 and buffer pad 82 upward away from the user's eyes. Releasing lever 91 resets friction block 92, fixing the third support rod 71 again, thus facilitating the securing of buffer pad 82 and preventing eye discomfort for the user.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
