[0034] The utility model relates to the technical field of medical devices, and in particular to a head-mounted eye cover for eye examination. The purpose is to solve the problem that when patients undergo eye examination, they need to prepare adhesive tape and oval sand blocks in advance, and then use them to cover the non-test eyes. In this test, the oval gauze block and adhesive tape are both disposable consumables, and they need to be replaced with new ones when different patients are examined, resulting in waste of consumables, which is not conducive to environmental protection and energy saving. In addition, if the eyes are not covered properly, it will affect the test results, draw wrong conclusions, and affect the patient's subsequent treatment and employment. To this end, the utility model provides a head-mounted eye mask for eye examination, which includes a head-mounted fixing, a fitting plate, an eye mask and a connecting rod. The fitting plate is connected to the head-mounted fixing so that it can be worn on the patient's head and fit with the forehead.

[0035] The head-mounted eye shielding device for eye examination provided by the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-2 The utility model provides a head-mounted eye shielding device for eye examination, which includes a head-mounted fixing part, a fitting plate 1, an eye mask 8 and a connecting rod 9. The fitting plate 1 is connected to the head-mounted fixing part so as to be worn on the patient's head and fit with the forehead. One end of the connecting rod 9 is connected to the fitting plate 1, and the other end of the connecting rod 9 is connected to the eye mask 8. The connecting rod 9 can move along its length direction relative to the fitting plate 1 to drive the eye mask 8 to shield different parts of the patient's eyes. Specifically, the fitting plate 1 can be made of hard plastic material.

[0037] In one embodiment, see Figure 1The head-mounted fixing device includes two straps 5, and each end of the fitting plate 1 is connected to a strap 5, one of the straps 5 is provided with a plurality of connection holes 11 distributed side by side at equal intervals, and the other strap 5 is provided with at least one connector 7, which can be inserted into different connection holes 11 so that the two straps 5 can be buckled together to tie the fitting plate 1 to the forehead of the patient's head.

[0038] In the above embodiment, the restraint belt 5 can be made of skin-friendly silicone material. The connector 7 on the restraint belt 5 is inserted into different connection holes 11 to adapt to the heads of different patients, so that the eye shield can be worn on the heads of different patients, which is simple and convenient to operate.

[0039] In one embodiment, the restraint belt 5 is provided with a plurality of holes 6 which are equally spaced and arranged side by side, and the holes 6 are located on the side of the connecting hole 11 or the connecting head 7 close to the bonding plate 1. The provision of the holes 6 is conducive to heat dissipation of the head when wearing, and improves comfort.

[0040] It should be noted that, although the head-mounted fixing described above is two straps 5, this is merely an example and does not limit the scope of protection of the present application. Without deviating from the basic principles of the present invention, the head-mounted fixing can be flexibly set according to actual usage and requirements.

[0041] In one embodiment, a locking member is provided between the connecting rod 9 and the bonding plate 1 to lock the connecting rod 9 after reaching a specified position so that the connecting rod 9 cannot move relative to the bonding plate 1. The locking member locks the position of the connecting rod 9 to prevent the eye mask 8 from being unable to completely cover the eyes due to the movement of the connecting rod 9, thereby improving the blocking stability of the eye mask 8 and facilitating the improvement of detection accuracy.

[0042] In one embodiment, see Figure 1-2 The locking member includes a plurality of teeth 3. The interior of the bonding plate 1 is a hollow structure. A sliding hole 2 communicating with the interior is provided on the side wall of the bonding plate 1 facing away from the forehead of the head. A plurality of teeth 3 are fixed side by side at equal intervals on the bottom wall of the sliding hole 2. A connecting rod 9 is inserted into the gap between two adjacent teeth 3 to be clamped and locked.

[0043] Specifically, one end of the connecting rod 9 passes through the sliding hole 2 and extends into the interior of the bonding plate 1 and is fixed with a chuck 10 to limit the displacement of the connecting rod 9 relative to the bonding plate 1 in a direction perpendicular to the forehead of the head. The chuck 10 is arranged so that the connecting rod 9 cannot be separated from the bonding plate 1, that is, the connecting rod 9 can only move along the length direction of the bonding plate 1 ( Figure 1When in use, the connecting rod 9 is pulled out from the gap between the teeth 3, and then the connecting rod 9 is moved to make the eye mask 8 reach the specified position, and then the connecting rod 9 is inserted into the corresponding gap between the teeth 3, and the two adjacent teeth 3 clamp the connecting rod 9, so that the connecting rod 9 cannot move in the left and right directions, thereby locking the position of the eye mask 8 in the left and right directions, ensuring that the eye mask 8 does not move during the process of covering the eyes, and improving the covering stability.

[0044] It should be noted that, although the locking member described above is a plurality of teeth 3, and the adjacent teeth 3 are used to clamp the connecting rod 9 to lock the position of the connecting rod 9, this is not restrictive, and the locking member can also be other structures. For example, see Figure 6 , the locking member includes two guide rods 14 and two locking members 13, a sliding hole 2 is provided on the side wall of the bonding plate 1 facing the forehead of the head, one end of the connecting rod 9 is inserted into the sliding hole 2 and can slide, and the two guide rods 14 are respectively fixed on the two side walls of the connecting rod 9, and the end of the guide rod 14 away from the connecting rod 9 penetrates the side wall of the bonding plate 1 and extends to the outside, and the locking member 13 is detachably connected to the guide rod 14 on the outside of the bonding plate 1. Exemplarily, the locking member 13 can be a nut, and the nut is threadedly connected to the guide rod 14. When adjusting the position of the eye mask 8, the nut is first moved in the direction away from the bonding plate 1. When the connecting rod 9 slides in the sliding hole 2 to drive the eye mask 8 to move to the specified position, the nut is moved in the direction close to the bonding plate 1 until the nuts on the two guide rods 14 are tightened and fit with the side wall of the bonding plate 1. At this time, the connecting rod 9 cannot move left and right, and the position of the eye mask 8 in the left and right directions is fixed. This is also within the scope of protection of this application.

[0045] In the above embodiment, by moving the connecting rod 9 to drive the eye mask 8 to move, the position of the eye mask 8 can be arbitrarily adjusted according to the position of the eye to cover different parts of the eye. It is suitable for the eye positions of different patients, has a wide range of applications, and is more convenient to use.

[0046] In one embodiment, the connecting rod 9 is bent to fit the eye mask 8 onto the patient's eye.

[0047] In one embodiment, see Figure 2 and Figure 3The connecting rod 9 includes a first branch rod 91 and a second branch rod 92. One end of the first branch rod 91 is hingedly connected to one end of the second branch rod 92 through a damping hinge. The other end of the first branch rod 91 is connected to the bonding plate 1, and the other end of the second branch rod 92 is detachably connected to the eye mask 8. The damping hinge is used to realize the hinge connection between the first branch rod 91 and the second branch rod 92. The damping hinge has a damping force. The second branch rod 92 can rotate relative to the first branch rod 91 only under the action of an external force, so as to ensure that the position of the eye mask 8 does not move after it fits the eye, thereby improving stability. It avoids excessive compression causing discomfort to the patient or inaccurate detection results due to small compression force and no complete shielding, thereby improving the patient's comfort and detection accuracy.

[0048] Specifically, a plug 12 is fixed to the other end of the second branch rod 92, the center line of the plug 12 is perpendicular to the center line of the second branch rod 92 in the length direction, and the eye mask 8 is provided with a socket 4 into which the plug 12 can be inserted, and there is an interference fit between the plug 12 and the socket 4, so that the plug 12 can be inserted into the socket 4 and can also be pulled out from the socket 4 under the action of an external force. The detachable connection between the eye mask 8 and the connecting rod 9 is achieved by the cooperation between the plug 12 and the socket 4, so that the eye mask 8 is easily replaced.

[0049] In one embodiment, see Figure 4-5 The eye mask 8 includes a first shielding portion 81 and a second shielding portion 82. The first shielding portion 81 and the second shielding portion 82 are an integrated structure. The first shielding portion 81 is a disc structure. The first shielding portion 81 is connected to the connecting rod 9. The second shielding portion 82 is used to fit the eyes. The upper end surface and the lower end surface of the second shielding portion 82 are both arc surfaces, and the end surfaces on both sides are arc surfaces concave inwardly to avoid the patient's nose bridge when worn.

[0050] In the above embodiment, inwardly concave arc surfaces are designed on both sides of the second shielding portion 82, so that the bridge of the nose can be avoided when shielding the eyes. The first shielding portion 81 is designed as a disc structure, and the shielding area is larger than that of the first shielding portion 81, which is more conducive to completely shielding the eyes and improves the detection accuracy.

[0051] The method of using the utility model is explained by taking the locking member as the teeth 3 as an example, specifically: the fitting plate 1 is worn on the patient's head through the restraining belt 5 and fits the forehead part, and then the connecting rod 9 is manually driven to drive the eye mask 8 to move left and right, so that the eye mask 8 reaches the position required to cover the eyes, and after the eye mask 8 reaches the specified position, the connecting rod 9 is inserted into the gap between the adjacent teeth 3 and clamped, and the second branch rod 92 is manually driven to drive the eye mask 8 to bend downward until the eye mask 8 fits and covers the eyes, thereby completing the overall wearing and covering operation of the eye shielding device.

[0052] The eye shield designed by the utility model can be worn on the head of a patient when undergoing an eye examination, and can be taken off when not undergoing an eye examination. It can be directly disinfected and cleaned for repeated use, thereby reducing the use of disposable medical consumables and saving examination costs.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the utility model.
