Description

TECHNICAL FIELD

[0001] The utility model belongs to ophthalmic nursing inspection device technical field especially, it relates to a cornea inspection device for ophthalmic nursing. BACKGROUND

[0002] The eyelid is located in front of the eyeball, and is divided into upper and lower eyelids, and is an important structure for protecting the eyeball. During the treatment and nursing of ophthalmology, the cornea of the patient often needs to be checked. When the medical staff checks the cornea of the patient, the upper and lower eyelids of the patient are usually directly supported open by hand, and then a magnifying glass is used for checking. During the checking process in this way, the medical staff needs to hold the eyelids of the patient with hands all the time, which leads to low checking efficiency, and the medical staff cannot concentrate on the cornea checking of the patient, resulting in poor checking effect. Therefore, a cornea checking device is needed to support open the eyelids of the patient to assist the medical staff in checking operation.

[0003] Although the current cornea checking device is various, there are still some problems. For example, in order to improve portability, the current cornea checking device is generally provided in a spectacle shape structure, and the upper and lower eyelids of the patient are supported open by two support plates at the center of the frame. Although this device can assist the medical staff to complete the checking operation, since the support plates are generally arranged at the center of the frame, and the support plates need to be supported by a support structure, the support structure is also located at the center of the frame. This leads to that the support structure at the center of the frame will shield the eyeball of the patient to a certain extent during checking, and further affects the development of the checking operation of the medical staff to a certain extent. At the same time, since the support plates arranged at the center can only support the center of the eyelid of the patient, the edges of the eyelid cannot be completely supported open, which further affects the development of the checking operation of the medical staff. Therefore, a cornea checking device for ophthalmic nursing is urgently needed to solve this problem. UTILITY MODEL CONTENTS

[0027] This utility model provides a corneal examination device for ophthalmic care, such as... Figures 1-5 As shown, it includes: a support frame 1, a support mechanism 2, and an eyelid opening mechanism 3;

[0028] There are two supporting frames 1, and the two supporting frames 1 are connected and fixed to each other, and are combined to form an integral structure. The supporting mechanism 2 is connected to the supporting frame 1, and the eyelid opening mechanism 3 is set on the supporting mechanism 2.

[0029] The support mechanism 2 includes an adjusting rod 21 and a support rod 22. One end of the support rod 22 is provided with a cavity. One end of the adjusting rod 21 is slidably connected in the cavity of the support rod 22, and the other end of the adjusting rod 21 is slidably connected to the top of the outer wall of the support frame 1.

[0030] The supporting mechanism 2 also includes a slide groove 23 and a locking block 24. The slide groove 23 is recessed on the outer wall of the supporting frame 1, and the locking block 24 is fixed on the adjusting rod 21 at one end away from the supporting rod 22, and the locking block 24 is slidably engaged in the slide groove 23.

[0031] The eyelid opening mechanism 3 includes a first support plate 31, a second support plate 32, an eyelid support plate 33, and a limiting and locking unit. The first support plate 31 is rotatably connected to the end of the support rod 22 away from the adjusting rod 21. The center of the second support plate 32 is rotatably connected to the center of the first support plate 31 through a rotating rod. There are two eyelid support plates 33, and the two eyelid support plates 33 are respectively located at one end of the first support plate 31 and the second support plate 32.

[0032] The eyelid opening mechanism 3 also includes a limiting plate 34 and a locking plate 35. A slot is provided through the first support plate 31. One end of the limiting plate 34 is fixed to the second support plate 32, and the other end passes through the slot of the first support plate 31 and is slidably connected to the first support plate 31.

Rackets are provided on the side where the limiting plate 34 and the locking plate 35 are close to each other, and the ratchets of the two are engaged with each other.

[0033] It needs to be explained that, in order to improve the portability, the existing corneal examination device is generally provided in a spectacle shape, and the support plate and the support structure arranged at the center of the frame are also located at the center of the frame, which causes the support structure at the center of the frame to block the patient's eyes to a certain extent during examination, thereby affecting the development of the examination work of the medical staff to a certain extent, and at the same time, since the support plate arranged at the center can only support the center of the patient's eyelid, the edges of the eyelid cannot be fully opened, which further affects the development of the examination work of the medical staff. In order to solve this problem, the supporting mechanism 2 and the eyelid opening mechanism 3 are arranged in the present scheme, the distance between the eyelid opening mechanism 3 and the patient's eyelid can be adjusted through the first support plate 31 and the second support plate 32 in the supporting mechanism 2, thereby effectively improving the application range of the examination device, and at the same time, the first support plate 31 can slide on the support frame 1, thereby the distance between the two adjacent eyelid opening mechanisms 3 can be adjusted according to the actual situation, further improving the application range of the examination device.

[0034] The arrangement of the two groups of eyelid opening mechanisms 3 on the support frame 1 enables the eyelid opening mechanism 3 to open the patient's eyelids on both sides, thereby effectively avoiding the blocking of the patient's eyes, facilitating the development of the examination work, and also enabling the patient's eyelids to be opened to the maximum extent and uniformly, avoiding the occurrence of edge blocking.

[0035] Specifically, in the present embodiment, the present scheme mainly includes a support frame 1, a supporting mechanism 2, an eyelid opening mechanism 3 and a belt 4. In use, the support frame 1 is bound to the patient's head by the belt 4, then the position of the adjusting rod 21 on the support frame 1 is adjusted according to the actual situation, so that the eyelid opening mechanism 3 is located at the appropriate position on both sides of the eyelid, then the distance between the adjusting rod 21 and the support rod 22 is adjusted, until the eyelid opening mechanism 3 is adjusted to an appropriate distance from the eyelid, then the first support plate 31 and the second support plate 32 are rotated, at this time the eyelid supporting plate 33 is linked and opens the patient's upper and lower eyelids, while the limiting plate 34 slides on the first support plate 31 and abuts against the lock plate 35, the limiting plate 34 and the lock plate 35 are locked by the ratchet, thereby locking the first support plate 31 and the second support plate 32, achieving the opening effect of the eyelid.

[0036] As shown in the further preferred embodiment of the utility model, Figures 1-5 The locking screw hole 25 is arranged in the sliding groove 23, a plurality of locking screw holes 25 are equidistantly arranged, a screw is arranged on the clamping block 24, and one end of the screw is screwed and locked in the locking screw hole 25.
