[0002] Many patients need to check the bilateral pupil and light reflex at any time, such as patients with craniofacial deformity, patients with eye diseases and some severe patients. The pupil light reflex examination includes direct light reflex and indirect light reflex. The method for checking the direct light reflex of the pupil is to irradiate the eye with a flashlight, specifically, the flashlight is scanned from the outside to the inside of the eye, and whether the pupil size of the eye is reduced is observed. If the pupil is reduced, it indicates that the direct light reflex of the side is normal. The method for checking the indirect light reflex of the pupil is to irradiate the eye with a flashlight, and at the same time, the hand is blocked between the two eyes, and whether the pupil size of the other eye is reduced is observed. If the pupil of the other side is reduced, it indicates that the indirect light reflex of the side is normal.

[0003] In the process of pupil light reflex examination, the size of the pupil sometimes needs to be measured or judged, so it is best to keep the examination conditions as same as possible for each examination, that is, the light source is the same, the position of the light source relative to the eye is the same, and the path of the light source scanning the eye is the same. However, for different medical staff, although the same flashlight can be used for pupil light reflex examination, the habits and gestures of different medical staff are not the same, especially when checking younger children, the children may not cooperate well, resulting in large differences in examination conditions at different time periods.

The drawings are schematic or conceptual drawings, and the relationship between the thickness and width of each part, as well as the proportional relationship between each part, etc., is not exactly the same as the actual value.

[0037] Figure 1 and Figure 2 The structure of the pupil light reflection examination device of one embodiment of the present application is shown in the schematic view, which includes a first frame 100, a second frame 200, a connecting part 300, a light source part 400 and a holding part 500. The first frame 100 and the second frame 200 are respectively connected to the two ends of the connecting part 300. The light source part 400 is pivotally connected to the second frame 200. The holding part 500 is connected to the connecting part 300.

[0038] The first frame 100 has a ring structure which is adapted to the shape of the human eye, and when examination, the first frame 100 is abutted to the outer periphery of the eye of the examinee, and the eye to be irradiated is exposed to the ring of the ring structure. The first frame 100 can also be provided with marks for alignment, such as Figure 2 The reference line 110 provided on the first frame 100 in the middle, when the first frame 100 is abutted to the outer periphery of the eye of the examinee, the reference line 110 can be aligned with the inner corner of the eye, thereby assisting in positioning the placement position of the first frame 100.

[0039] In some embodiments, the ring structure of the first frame 100 adopts a ring-shaped air bag, so that the contact between the pupil light reflex examination device and the human body has a buffer.

[0040] In some embodiments, the ring structure of the first frame 100 is provided with a skin-friendly coating to improve the touch feeling.

[0041] The connecting part 300 includes connecting rods 310, 320, 330, the two ends of the connecting rods 310, 320, 330 are connected to the first frame 100 and the second frame 200 respectively, and the connecting part 300 limits the distance between the first frame 100 and the second frame 200, that is, also limits the irradiation distance of the light source part 400 connected to the second frame 200 to the first frame 100, so that the distance of the light source part 400 irradiating the eye of the examinee is uniform each time.

[0042] In this embodiment, the connecting part 300 adopts three connecting rods extending along a straight line to connect the first frame 100 and the second frame 200, and the number and shape of the connecting rods are not limited here, which aims to enable the first frame 100 and the second frame 200 to stably maintain a distance, and similarly, it is not limited to using a rod, and a plate-shaped connecting body can also be used to achieve the same effect. However, the connecting part 300 adopts a rod, which has relatively better effect, one is to save materials, and the other is to reduce the shielding, to provide a larger visual range for the user, which is beneficial for him to observe the pupil of the examinee.

[0043] The second frame 200 is pivotally connected with the light source part 400, specifically, the light source part 400 is symmetrically provided with a cylindrical protrusion 410, and the second frame 200 is provided with a through hole 210 matched with the protrusion 410, one side of the through hole 210 has an opening 220, the protrusion 410 of the light source part 400 can be placed at the opening 220, and the protrusion 410 can be pushed into the through hole 210 by external force, so that the cylindrical protrusion 410 can rotate in the through hole 210, and the light source part 400 as a whole can rotate around the axis of the cylindrical protrusion 410.

[0044] Preferably, the rotation of the light source part 400 can not be too smooth, and can have certain resistance, so that the light source part 400 can be kept at a position after being rotated to the position and the external force for rotating the light source part 400 is removed, by the size or material selection of the cylindrical protrusion 410 and the through hole 210.

[0045] In the embodiment, the second frame 200 has a semi-ring structure as a whole, and similar to the foregoing, such arrangement can save manufacturing materials, and meanwhile can reduce the shielding and facilitate the user to observe the pupil of the examinee. Similarly, the shape of the second frame 200 is not limited here, and is intended to be suitable for being connected with the connecting part 300 and cooperating with the light source part 400 to provide a corresponding structure so that the light source part 400 can be rotated at a desired position.

[0046] The light source part 400 provides light for the pupil light emission examination, and the light requirement of the light source part 400 is that when the light direction of the light source part 400 is towards the first frame 100 and within the rotatable range thereof, the light can cover most of the range of the first frame 100, and reflected in the angle of the examinee, that is, the light range can enable the light to sweep over the eye from the outside of the outer canthus to the outside of the inner canthus.

[0047] The rotation range of the light source part 400 is easily realized by the structure of the second frame 200, and the light source part 400 can even be arranged to be rotatable by 360 degrees, but such large range rotation is not conducive to the use of the device, which will increase the difficulty of the user operation, because the range to be provided is relatively limited, and the light source part 400 does not need to be rotated in a large range.

[0048] Therefore, the limiting part 230 extending towards the light source part 400 is arranged on the second frame 200, and no matter which direction the light source part 400 rotates, it will finally contact and abut against the limiting part 230, as shown in Figure 3 and Figure 4 so as to limit the rotation range of the light source part 400 by the limiting part 230.

[0049] The light source part 400 is provided with a press switch 420, which is arranged at one end opposite to the light direction of the light source part 400, and usually when the device of the embodiment is used, the finger for pressing the press switch 420 to turn on the light source part 400 is also used to drive the rotation of the light source part 400, so the press surface of the press switch 420 is provided with a concave-convex texture 421, so as to provide a certain friction for the finger to drive the rotation of the light source part 400 by driving the press switch 420, so as to facilitate the rotation operation of the light source part 400.

[0050] From the above description of the pupil light reflection examination device of the embodiment, it can be seen that the whole device is mainly of frame structure, which has the advantages of saving manufacturing materials and reducing shielding, but has the disadvantage of inconvenient handheld operation, mainly the poor stability of holding.

[0051] To this end, the pupil light reflection examination device of the embodiment is further provided with a holding part 500 connected with the connecting part 300, specifically connected with the side surface of the connecting rod 330. The holding part 500 comprises finger rings 510, 520, and the user can put fingers into the finger rings 510, 520, so as to conveniently hold the whole device. For example, when the right eye of the examinee is examined, the right index finger and middle finger of the user can be put into the finger rings 510, 520, so as to stably hold the examination device, and the press switch 420 of the light source part 400 can be opened by the right thumb, and the rotation of the light source part 400 can be driven. According to the use habit of the individual, other holding methods can also be adopted, such as putting the middle finger and ring finger into the finger rings 510, 520, which is not limited herein.

[0052] In the embodiment, the finger rings 510, 520 are of closed loop structure, and in other embodiments, all or part of the finger rings are provided as non-closed loop structure, such as providing a gap (disconnection) on the loop structure of the finger ring 510, which has the advantage of stronger adaptability to the thickness of the finger. When the outer diameter of the finger approaches or even exceeds the inner diameter of the finger ring, the gap on the finger ring can be set to make the finger ring be expanded to adapt to the outer diameter of the finger.

[0053] On the other hand, when the children are examined, the cold medical equipment is always difficult to be friendly to the children, and therefore the surface color of the device in the embodiment can adopt bright color or camouflage color, which has some design sense in combination with the shape structure of the device itself, which can reduce the rejection of the children to a certain extent.

[0054] The preferred embodiment of the utility model is described in detail above. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the utility model. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the utility model shall be within the protection scope determined by the claims.
