[0028] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] The present invention provides a head-mounted device for assisting ophthalmology retinoscopy in recruitment of pilots, such as Figure 1 As shown, it comprises a headband 1, and a point light source 6 is provided on the upper side of the front center of the headband 1. Preferably, the point light source 6 is arranged at the forehead, and the point light source can be a small light bulb, which is the gaze point of the subject.

[0030] The head-mounted device for assisting retinoscopy also includes a head circumference adjustment component 9, which can adjust the size of the headband 1. By adjusting the head circumference adjustment component 9, the head circumference of different doctors can be adapted. Figure 1 In the embodiment, the head circumference adjustment component 9 is arranged at the back of the head and is a buckle type. The head circumference adjustment component 9 can also be a knob type, and the head circumference size can be adjusted by rotating the knob.

[0031] like Figure 2 As shown, the front part of the headband 1 is provided with a slide groove 4, preferably, the slide groove 4 is located between the outer sides of the eyebrow arches on both sides, and a visor 5 is installed in the slide groove 4, and the visor 5 can slide along the slide groove 4, and the visor 5 can be flipped up and down. The slide groove 4 can make the visor 5 move to the non-operating eye, and the visor 5 is lowered to cover the non-operating eye of the examiner, reducing the discomfort and inaccuracy caused by squinting. When it is not needed, the visor 5 slides to the place where it does not affect the use of the head-mounted device for auxiliary retinoscopy, and flips up.

[0032] The headband 1 is provided with a tension sensing component 2 at the left eyebrow arch position, the first end of the tension sensing component 2 is connected to the headband 1, the second end of the tension sensing component 2 is provided with a connector 3, and the connector 3 can be connected to a frame or an optometry table; a vibration sensing device is provided in the headband 1; when the tension sensing component 2 is connected to the frame or the optometry table, the force on the tension sensing component 2 is less than the tension threshold, and the vibration sensing device vibrates. When the doctor is performing retinoscopy, he needs to keep a certain distance from the person being examined. The utility model uses the tension sensing component 2 to solve the problem of difficult distance control during the retinoscopy in ophthalmology during recruitment of pilots.

[0033] The head-mounted device for assisting retinoscopy also includes a wireless headset 8, which is arranged on the right side of the headband 1. The wireless headset 8 can be connected to the optometry device to obtain the optometry degree in real time during the optometry process. Preferably, a bone conduction headset with a Bluetooth connection function is provided on the right side, which can be connected to the optometry device to obtain the optometry degree in real time during the optometry process, and can also be connected to a mobile phone and other Bluetooth devices.

[0034] The head-mounted device for auxiliary retinoscopy also includes a gravity sensing lamp 7; the gravity sensing lamp 7 is arranged on the front right side of the headband 1; preferably, it is arranged on the right side of the forehead. When the angle between the head-mounted device for auxiliary retinoscopy and the horizontal plane is less than the first angle threshold, the gravity sensing lamp 7 is turned off; when the angle between the head-mounted device for auxiliary retinoscopy and the horizontal plane is greater than or equal to the first angle threshold, the gravity sensing lamp 7 is turned on. The head-mounted device for auxiliary retinoscopy also includes a gravity sensing lamp 7 switch. When the gravity sensing lamp 7 switch is turned on, the gravity sensing lamp 7 will not be turned off due to the change in the angle of the head-mounted device for auxiliary retinoscopy.

[0035] There are two ways to use the gravity sensing lamp 7. One is to use the gravity sensing lamp 7 switch type. When the switch is turned on, the light is on, and when the switch is turned off, the light is off. The other is the gravity sensing type. When the angle between the head-mounted device for auxiliary retinoscopy and the horizontal plane is less than the first angle threshold, that is, when looking straight ahead, the gravity sensing lamp 7 is turned off; when the angle between the head-mounted device for auxiliary retinoscopy and the horizontal plane is greater than or equal to the first angle threshold, that is, when lowering the head, the gravity sensing lamp 7 is turned on to facilitate writing the optometry results. The gravity sensing function can be realized by using a horizontal sensor. Preferably, the corresponding function can be selected through the gravity sensing lamp 7 switch. The gravity sensing lamp 7 switch is provided with three items of "on", "off" and "gravity sensing". When the switch is turned to "gravity sensing", the gravity sensing type is selected; when turned on, the light is always on; when turned off, the light is always off. Doctors can choose to use according to actual needs.

[0036] The head-mounted device for assisting retinoscopy and optometry designed by the present invention also includes a rechargeable battery, which can be externally connected to the headband 1 or arranged inside the headband 1 for power supply. It also includes a main switch, and when the main switch is turned on, the head-mounted device for assisting retinoscopy and optometry is started.

[0037] In the present invention, the tension sensing component 2 can have various designs.

[0038] Embodiment 1:

[0039] The tension sensing component 2 is a tension sensing line, and the tension sensing line is 1 meter long.

[0040] Embodiment 2:

[0041] The tension sensing component 2 is a tension sensing line, and the tension sensing line is 1 meter long. The headband 1 is also provided with a winding component, which can wind the tension sensing line.

[0042] Embodiment 3:

[0043] The tension sensing component 2 is a tension sensing line, and the tension sensing line is 1 meter long. The headband 1 is also provided with a wire collection component, which is connected to the first end of the tension sensing line 2 and can collect the tension sensing line 2 into the headband 1.

[0044] In embodiments 1 to 3, the tension sensing component 2 is a 1-meter-long tension sensing wire. During retinoscopy, the doctor and the person being examined need to maintain a 1-meter inspection distance. A connector 3 is provided at the second end of the tension sensing wire. Figure 2 The middle one is a hook. There are many options for connector 3, such as a strap. The connector can be connected to the frame or to the optometry table. If the distance between the doctor and the person being examined is less than 1 meter, the tension sensing line will obviously lose tension, and the force on the tension sensing component 2 is less than the tension threshold, so the vibration sensing device vibrates. Example 1 does not take the wire winding problem into consideration; Example 2 uses a winding component, and the doctor can wind the tension sensing component 2 around the winding component for easy storage; Example 3 provides a wire winding component that can automatically wind up the wire, reducing the doctor's workload.

[0045] Embodiment 4:

[0046] The tension sensing component 2 is a tension sensing line, the length of which is greater than 1 meter, and a mark is set on the tension sensing line 1 meter away from the second end; the headband 1 is provided with a wire clamping component, and the wire clamping component can be fixed at any position of the first end of the tension sensing line.

[0047] Embodiment 5:

[0048] The tension sensing component 2 is a tension sensing line, the length of which is greater than 1 meter, and a mark is provided on the tension sensing line 1 meter away from the second end; the headband 1 is provided with a line clamping component, which can be fixed at any position of the first end of the tension sensing line. The headband 1 is also provided with a winding component, which can wind the tension sensing line.

[0049] Embodiment 6:

[0050] The tension sensing component 2 is a tension sensing line, the length of which is greater than 1 meter, and a mark is provided on the tension sensing line 1 meter away from the second end; the headband 1 is provided with a line clamping component, which can be fixed at any position with the first end of the tension sensing line. The headband 1 is also provided with a wire retracting component, which is connected to the first end of the tension sensing line 2, and the wire retracting component can retract the tension sensing line 2 into the headband 1.

[0051] Embodiment 7:

[0052] The tension sensing component 2 is a tension sensing line, the length of which is greater than 1 meter, and an identification is provided on the tension sensing line 1 meter away from the second end; the headband 1 is also provided with a wire taking-up component, which is connected to the first end of the tension sensing line 2, and the wire taking-up component can take up the tension sensing line 2 into the headband 1; the fixing element can limit the wire taking-up component from taking up the tension sensing line.

[0053] In Examples 4 to 7, the tension sensing component 2 is a tension sensing line with a length of more than 1 meter, and the tension sensing line is provided with a mark 1 meter away from the second end. This design takes into account that due to various reasons, the distance between the doctor and the examiner exceeds 1 meter, such as 1 meter 1; or the distance between the doctor and the examiner is 1 meter, but the distance between the head-mounted device for auxiliary retinoscopy and the examiner exceeds 1 meter. As in Examples 1 to 3, if the length of the tension sensing line is limited, the doctor cannot use the head-mounted device for auxiliary retinoscopy normally. In Examples 4 to 6, a wire clamping component is used, and in Example 7, it is a fixed element on the wire take-up component. The wire clamping component can have a variety of designs, such as a simple clip; the fixed element has a locking function and can limit the rotation of the shaft of the wire take-up component. When in use, the doctor selects a suitable inspection position, extends the tension sensing line, and connects the connector 3 to the frame or the optometry table. According to the actual retraction of the tension sensing line, the tension sensing line is tightened, and the tension sensing line is clamped with the wire clamping component or the fixed element is used to limit the retraction of the wire take-up component.

[0054] In Examples 1 to 3, since the first end of the tension sensing line is fixed, a tension sensor is provided at the first end to realize the tension sensing function. In Examples 4 to 6, the first end of the tension sensing line is fixed by a wire clamping assembly, and a tension sensor needs to be provided on the wire clamping assembly, which is relatively complex to realize industrial implementation. In Example 7, the tension sensing line actually realizes length control by limiting the rotation of the take-up assembly through a fixed element, and a corresponding sensor needs to be provided in the take-up assembly to realize the tension sensing function.

[0055] The head-mounted device designed by the present invention for assisting ophthalmic retinoscopy in flight recruitment has a simple structure and solves the problems of difficult distance control, difficult gaze point finding, and easy fatigue of monocular operation in the process of ophthalmic retinoscopy in flight recruitment. According to the characteristics of medical selection optometry for flight recruitment, the use of this head-mounted device can improve the efficiency and accuracy of optometry.

[0056] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
