Description

Technical Field

[0001] The utility model relates to the technical field of pressure detection equipment, in particular to an eye pressure detector. Background Art

[0002] With social and economic development, people's living standards are constantly improving, and visual health is receiving increasing attention. Glaucoma is the world's leading irreversible blinding eye disease, responsible for 50% of blindness worldwide. Its incidence rate is 1-2% across all age groups, and as high as 5-6% in people over 50 years old, posing a serious threat to people's visual health. High intraocular pressure (IOP), the most obvious characteristic of glaucoma and also the cause of blindness, is the monitoring of IOP. Tonometers are becoming increasingly familiar medical devices, making them a crucial tool for preventing and treating glaucoma.

[0003] A search of the publication number (CN114305322A) discloses a tonometer and a method for measuring intraocular pressure. In order to ensure that the pressure detector accurately controls the pupil advancement depth when the tonometer detects intraocular pressure, traditional tonometers generally use the coordination between a motor and a transmission structure to drive the pressure detector on the tonometer to move. Due to the presence of structures such as the motor in the traditional tonometer, the tonometer is large in size and weight, and the production and processing costs of the tonometer are high. In addition, when the user needs to control the movement distance of the pressure detector, the traditional tonometer uses the number of rotations of the motor output end to control the movement distance of the pressure detector, which is not accurate enough and the user operation is complicated. In addition, the structure required to detect the number of rotations of the motor output end is relatively complex, further increasing the production and processing costs and the size of the tonometer. In addition, the existing tonometer is not provided with a positioning structure, and the probe is prone to deviation when the user uses it, resulting in errors in the detected data.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-7 The present invention provides an embodiment of an eye pressure detector, comprising:

[0039] The intraocular pressure detection structure 6 obtains eye pressure information by squeezing after contacting the user's eyes;

[0040] An information transmission structure 5 is located at one end of the intraocular pressure detection structure 6 and includes an information processing module 51 and a displacement measurement structure. The displacement measurement structure includes grating bars 55 and a grating sensor 57. The grating bars 55 are connected to the intraocular pressure detection structure 6. The movement of the intraocular pressure detection structure 6 drives the grating bars 55 to move within the sensing area of ​​the grating sensor 57.

[0041] A driving unit 2, located at one end of the information transmission structure 5, is used to control the movement of the intraocular pressure detection structure 6;

[0042] A positioning unit 8 is provided on the intraocular pressure detection structure 6 and is used to project a positioning light toward the user's eyes;

[0043] The user pushes the drive unit 2 with force by hand to move, driving the information transmission structure 5 and the intraocular pressure detection structure 6 to move, so that the intraocular pressure detection structure 6 can test the skin pressure, and the user can use the assistance of the positioning unit 8 to align the intraocular pressure detection structure 6 with the middle position of the user's eye, which can avoid the user's deviation during use, thereby causing deviation in eye pressure detection. After the user completes the detection, the drive unit 2 drives the information transmission structure 5 and the intraocular pressure detection structure 6 to reset.

[0044] In this embodiment, the positioning unit 8 is located on the front end shell 3, specifically a ring light embedded in the front end shell 3, which can present a ring light similar to the eye contour at the user's eyes during use. When in use, the user can use the positioning unit 8 similar to the eye contour to assist in positioning.

[0045] In this embodiment, the intraocular pressure detection structure 6, the information transmission structure 5 and the driving unit 2 are arranged inside the rear end shell 1 and the front end shell 3, and the support structure 4 is provided on the top and bottom of the rear end shell 1. The intraocular pressure detection structure 6, the information transmission structure 5 and the driving unit 2 are protected by the rear end shell 1 and the front end shell 3 to prevent the intraocular pressure detection structure 6, the information transmission structure 5 and the driving unit 2 from being affected by the external environment and malfunctioning. Moreover, when the user uses it, the user uses the support structure 4 to adjust the distance between the probe 65 and the skin to prevent the user from causing skin injuries due to excessive force.

[0046] In this embodiment, the drive unit 2 includes a push rod 20 and a limit sleeve rod 23. The push rod 20 is movably installed in the middle position of one end of the rear end shell 1. The outer surface of the push rod 20 is installed with a reset spring 21 and a ring 22. The limit sleeve rods 23 are installed on both sides of the other end of the rear end shell 1. The outer surface of the limit sleeve rod 23 is sleeved with a sliding rod 24 fixedly connected to the information transmission structure 5. The other end of the push rod 20 is connected to the information transmission structure 5 through a first screw 25. The user's hand pushes the push rod 20 to drive the information transmission structure 5 to move, and the limit sleeve rod 23 and the sliding rod 24 play a role in limiting the moving direction of the information transmission structure 5. When the user lets go, the reset spring 21 can drive the push rod 20 to reset, so that the information transmission structure 5 moves to its initial position.

[0047] In this embodiment, the support structure 4 includes a support rod 40, and the rear end shell 1 is installed with the support rod 40 through the connecting structure. A protective cover 41 is installed at the other end of the support rod 40. The protective cover 41 is made of soft silicone or other rubber materials. The outer surface of the support rod 40 and the inner surface of the connecting structure are both provided with threads. The support rod 40 and the connecting structure are connected to each other through threaded rotation. The user controls the extension amount of the support rod 40 on the connecting structure by rotating the support rod 40, thereby controlling the distance between the probe 65 on the intraocular pressure detection structure 6 and the skin.

[0048] In this embodiment, the information transmission structure 5 includes an information processing module 51. A display screen 52 is mounted on the top of one end of the information processing module 51. A battery 7 and an information acquisition module 53 are mounted on the top and bottom of the other end of the information processing module 51, respectively. A displacement measurement structure is mounted on the bottom of the other end of the information acquisition module 53. The information processing module 51 is provided with a charging port. The information acquisition module 53 and the displacement measurement structure cooperate to measure the distance moved by the information transmission structure 5 and the pressure data of the pressure detector 60 in real time. The information processing module 51 can feedback the measured movement distance on the display screen 52, so that the user can intuitively understand the skin pressure. In other embodiments, the information processing module 51 is also connected to a prompt unit, such as a buzzer or speaker, to prompt the user during use.

[0049] In this embodiment, the displacement measurement structure on the information acquisition module 53 includes a connecting member 54 and a grating sensor 57. A second screw 56 is installed at the bottom of the other end of the information acquisition module 53. The connecting member 54 is installed at the bottom of the other end of the information acquisition module 53 through the second screw 56. A grating bar 55 is slidably installed at the bottom of the other end of the information acquisition module 53 through the connecting member 54. A grating sensor 57 is installed at the bottom end of the rear end shell 1. A plurality of rectangular openings are opened at the top of the grating bar 55. The user can accurately measure the moving distance of the information transmission structure 5 through the cooperation between the grating bar 55 and the grating sensor 57, which is convenient for the user to control the pushing distance of the driving unit 2. In addition, a sensing range is set on the grating bar 55. When the grating sensor 57 moves out of the sensing range on the grating bar 55, the pressure detector 60 is turned off so that the pressure detector 60 no longer performs pressure detection on the user's eyes, thereby avoiding eye injuries to the user during detection.

[0050] In this embodiment, the intraocular pressure detection structure 6 includes a pressure detector 60, a mounting sleeve 61 is installed at the other end of the pressure detector 60, a connecting rod 62 is installed inside the mounting sleeve 61, a connecting sleeve 63 is slidably installed on the outer surface of the connecting rod 62, a fixing sleeve 64 is installed at the other end of the connecting sleeve 63, and a probe 65 is installed on the outer surface of the fixing sleeve 64. When the intraocular pressure detection structure 6 is pushed by the information transmission structure 5, the probe 65 can press the user's skin and trigger the user's pressure detector 60, thereby achieving the purpose of testing the user's skin pressure. Figure 8 As shown, there are two types of probes 65, one with a flat head and the other with a pointed head. Users can use different probes 65 according to their needs.

[0051] In this implementation, according to Figure 9 As shown, in the initial stage of the device, the voltage in the pressure detector 60 in the intraocular pressure detection structure 6 is stable and is 1.9V. During the user use stage, the voltage increases as the user squeezes, and the detected pressure corresponds to the voltage one by one.

[0052] See Figure 8-9 The present invention also provides a second embodiment of an eye pressure detector. Compared with the first embodiment, the second embodiment has the following differences:

[0053] In the second embodiment, positioning unit 8 is a laser generator embedded within probe 65 of the intraocular pressure detection mechanism 6. In this embodiment, the laser generator has a power of less than 0.39 mW. Due to the unidirectional collimation of the laser, when the user can see the laser light source, it can be confirmed that the probe 65 of the intraocular pressure detection mechanism 6 of the ocular pressure detector is precisely aligned with the center of the user's eye, thus achieving positioning and ensuring more accurate intraocular pressure measurement.

[0054] Working principle: The user first locates the device according to the positioning light, and then rotates the support rod 40 according to needs to adjust the extension of the support structure 4 so that the protective cover 41 can fit closely to the skin.

[0055] The user then pushes the drive unit 2, causing the drive unit 2 to drive the intraocular pressure detection structure 6 and the grating strips 55 to move within the rear end housing 1 and the front end housing 3. Before the intraocular pressure detection structure 6 contacts the user's eye skin, the electrical level obtained by the information processing module 51 remains at a constant low level, referred to as the no-load level. When the probe 65 on the intraocular pressure detection structure 6 presses the user's skin, the detector 60, which is subjected to the skin's reaction force, sends an electrical signal to the information processing module 51, causing the electrical level received by the information processing module 51 to increase. At this point, the information processing module 51 begins to record the electrical level signal in real time. At the same time, the information processing module 51 begins to obtain the movement distance of the intraocular pressure detection structure 6 in real time based on the displacement measurement structure and determines whether it has reached a preset value. When the movement distance of the intraocular pressure detection structure 6 reaches the preset value, the information processing module 51 stops recording the electrical level signal and prompts the user that the pressure measurement process has ended. The information processing module 51 calculates and outputs the intraocular pressure value to the display screen 52 based on the recorded electrical level signal comparison table.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or scope of the present invention. Therefore, the embodiments of the present invention are illustrative and non-restrictive. The scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations within the meaning and scope of equivalents of the claims be encompassed within the present invention. Any reference numerals in the claims should not be construed as limiting the claim to which they relate.
