Description

Technical Field

[0001] The utility model relates to the technical field of preventing and controlling myopia, and in particular to a head-down alarm device for preventing and controlling myopia by avoiding increased intraocular pressure. Background Art

[0002] Myopia, a condition in which parallel light rays passing through the eye's refractive system, cannot accurately focus on the retina when the eye is relaxed and accommodated, but instead focus in front of the retina. It is a major factor affecting vision during childhood development. It is projected that by 2050, the global prevalence of myopia will rise to 49.8%, with high myopia expected to reach 9.8%. Myopia has become a global public health issue that endangers eye health. In recent years, the incidence of myopia has remained above half, with a significant increase in severity and younger age. Therefore, research into the prevention and treatment of myopia remains of great social and economic significance.

[0003] In recent years, with the continued advancement of research into the pathogenesis of myopia, several new factors have been proposed, including intraocular pressure (IOP). IOP has long been considered to have a role in the development and progression of myopia and continues to attract attention. Studies have shown that IOP is sensitive to changes in body and head position. Maintaining a continuous neck flexion (45°) while reading can lead to elevated IOP, whereas maintaining an upright neck position (looking straight ahead) can maintain IOP. The increase in IOP from baseline with a lowered head reading position is greater than that observed with an upright head position. The increased IOP observed with neck flexion may be related to the increased episcleral venous pressure (EVP) caused by the lowered head position. Studies have shown that for every 0.83 mmHg increase in EVP, IOP increases by 1 mmHg. Short-term fluctuations in IOP can lead to a significant increase in axial length and accelerate myopia progression. Therefore, maintaining an upright neck position while reading can maintain a relatively stable IOP level, thereby controlling myopia progression.

[0004] Therefore, developing a device that can effectively monitor and remind users to change their head-down reading posture is of great significance for controlling the progression of myopia. Utility Model Content

[0038] Reference Figures 1 to 3The present invention provides a head-down alarm device for preventing elevated intraocular pressure and preventing myopia, comprising: an elastic fitting component 1, a first resistance transmission sheet 2, a second resistance transmission sheet 3, a first sliding contact 20, a second sliding contact 30, a signal processing module 5, and a wireless module 6;

[0039] The fitting member 1 is used to fit on the back of the human neck. The fitting member 1 in the form of neck adhesive is designed to be compact and comfortable to wear.

[0040] One end of the resistance transmission sheet 1 2 and the resistance transmission sheet 2 3 are both fixed on the fitting component 1, and the resistance transmission sheet 1 2 and the resistance transmission sheet 2 3 are staggered up and down;

[0041] The sliding contact 1 20 is provided on the other end of the resistance transmission sheet 1 2 and contacts the resistance transmission sheet 2 3; the sliding contact 2 30 is provided on the other end of the resistance transmission sheet 2 3 and contacts the resistance transmission sheet 1 2;

[0043] The corresponding ends of the signal processing module 5 are electrically connected to the sliding contact 1 20 and the sliding contact 2 30 respectively, and are used to detect the change in the resistance value at both ends of the sliding contact 1 20 and the sliding contact 2 30, so as to determine whether the user's neck is in a lowered state;

[0044] The corresponding end of the wireless module 6 is electrically connected to the corresponding end of the signal processing module 5, and is used to transmit the signal output by the signal processing module 5 to the user's handheld terminal. The user can receive alarms or data of the head-down state through the handheld terminal; the handheld terminal includes one of a mobile phone, an iPad, and a tablet computer.

[0045] Furthermore, the fitting component 1 includes an elastic fabric 101, silicone patches 102 arranged at both ends below the elastic fabric 101, and a plurality of silicone suction cups 103 placed on the silicone patches 102. The use of the elastic fabric 101 enables the alarm device to expand and contract with the movement of the neck, thereby detecting the bending state of the neck. The silicone patches 102 and the plurality of silicone suction cups 103 are used to enhance the adhesion between the fitting component and the human neck, providing a stable fitting effect.

[0046] Furthermore, the elastic fabric 101 is provided with fixing points 1 (201) and 2 (301) at both ends of its upper surface. One end of the resistance transmission piece 1 (2) is fixed to fixing point 1 (201), and one end of the resistance transmission piece 2 (3) is correspondingly fixed to fixing point 2 (301). Fixing points 1 (201) and 2 (301) are used to secure the positions of the resistance transmission pieces 1 (2) and 2 (3), ensuring their proper movement when the neck is bent. The signal processing module 5 is connected to the sliding contact 1 (20) and sliding contact 2 (30) via circuit connection line 1 (501) and circuit connection line 2 (502), respectively, to facilitate transmission of resistance change signals.

[0047] Furthermore, the head-down alarm device for preventing and controlling myopia by avoiding increased intraocular pressure also includes a housing 4. The housing 4 is installed in the middle of the elastic fabric 101 to improve the aesthetics of the device and make it more suitable for wear. Secondly, heat dissipation holes can be opened on the housing 4 to facilitate heat dissipation of the signal processing module 6, the wireless module 7, and the power module. The housing 1 is also provided with a PCB board, and the PCB board is also provided with a power module 7. The signal processing module 6 and the wireless module 7 are both provided on the PCB board.

The power module 7 is configured as a battery, which can be a rechargeable lithium battery.

[0048] The working principle of this utility model is as follows:

[0049] The device is in the form of a neck adhesive. When in use, the fitting component 1 of the device is fitted to the back of the human neck. After the elastic fabric 101 fits the neck, if the neck bends and lowers the head, the length of the device will be stretched, and the resistance transmission plate 1 2 and the resistance transmission plate 2 3 fixed at both ends of the fixed point 1 201 and the fixed point 2 301 will be pulled in opposite directions; thereby, the relative distance between the sliding contact 1 20 and the sliding contact 2 30 will become shorter, thereby changing the resistance value. At the same time, the signal processing module 5 will detect that the resistance value at both ends becomes smaller, thereby knowing that the wearer is in a head-down state at this time, and further transmitting the signal via the wireless Bluetooth module of the wireless module 6 to the APP of the mobile phone, realizing real-time observation, recording and alarm reminder of data.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
