Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a wearable intraocular pressure measurement device. Background Technology

[0002] A tonometer is an instrument used to measure intraocular pressure, which can aid in the diagnosis of eye diseases such as cataracts and glaucoma. Intraocular pressure measurement obtains real-time intraocular pressure values, records pressure fluctuation trends, and allows for the adjustment of processing parameters to maintain target pressure and prevent tissue damage caused by long-term abnormal pressure.

[0003] A wearable intraocular pressure measuring device is disclosed in utility model patent CN223416215U. This device overcomes the shortcomings of existing portable home tonometers, which are handheld and prone to shaking due to the user's inability to remain still, thus affecting the measurement results. However, the disassembly and installation of the tonometer, and the alignment of the tonometer with the user's left or right eye, are cumbersome, and the user is prone to touching the tonometer and probe, leading to probe contamination. Summary of the Invention

[0004] To overcome the problems of cumbersome operation when disassembling and installing the pressure gauge to align it with the user's left or right eye, and the user's easy contact with the pressure gauge and probe leading to probe contamination, this invention provides a wearable intraocular pressure measurement device, including a wearable frame, and further comprising:

[0006] The mounting frame is set on the wearable frame;

[0007] The calibration mechanism is set on the wearable frame, and the calibration mechanism includes a slide plate that is slidably connected inside the wearable frame and a first adjustment rod installed on the slide plate;

[0008] A measuring mechanism is installed at the end of the first adjusting rod away from the slide plate. The measuring mechanism includes an outer frame connected to the first adjusting rod and a pressure gauge disposed inside the outer frame. The slide plate is used to drive the first adjusting rod, the outer frame and the pressure gauge to move in the horizontal direction.

[0009] Preferably, the calibration apparatus further includes:

[0010] A vertical panel installed on the wearable frame;

[0011] The first and second through slots are located inside the wearable frame;

[0012] The first telescopic rod installed on the outside of the vertical plate and the locking assembly connected to the telescopic end of the first telescopic rod.

[0013] Preferably, the card slot assembly includes:

[0014] A limiting cylinder is installed on the telescopic end of the first telescopic rod; the limiting cylinder is used to limit.

[0015] A sliding rod is slidably connected inside the limiting cylinder, and a positioning plate is installed below the sliding rod. The positioning plate is adapted to the first through groove, and the limiting cylinder is used to limit the position of the sliding rod.

[0016] Preferably, the card slot assembly further includes:

[0017] The base plate is located above the sliding rod;

[0018] A center rod is mounted on the base plate, and a top plate is set above the center rod.

[0019] Preferably, the card slot assembly further includes:

[0020] A sliding plate is slidably connected to the outside of the center rod, and a gasket is set on the sliding plate. The gasket is used to fix the top plate, thereby limiting the position of the locking rod.

[0021] A locking rod is installed below the sliding plate. The locking rod is adapted to the second through groove. A gasket is used to fix it to the top plate, thereby restricting the position of the locking rod.

[0022] Preferably, the measuring mechanism further includes:

[0023] The second telescopic rod is installed on the outer frame;

[0024] A retaining ring located inside the outer frame and a contact component located inside the retaining ring.

[0025] Preferably, the measuring mechanism further includes:

[0026] The lifting rod is installed inside the outer frame;

[0027] The outer cylinder is installed on the telescopic end of the lifting rod, and the pressure gauge is slidably connected to the inside of the outer cylinder;

[0028] The second adjusting rod is installed on the pressure gauge and passes through the outer cylinder.

[0029] Preferably, the contact assembly includes:

[0030] Connecting pipe installed outside the fixing ring;

[0031] The first chamber and the second chamber are located inside the fixed ring;

[0032] An internal ring is located inside the fixed ring and is used to contact the pressure measuring end of the disinfection pressure gauge.

[0033] Preferably, the contact assembly further includes:

[0034] A sliding ring that is slidably connected inside a fixed ring;

[0035] The moisture-absorbing ring, located inside the sliding ring, is used to absorb the disinfectant liquid outside the test end.

[0036] This invention provides a wearable intraocular pressure measurement device. It has the following beneficial effects:

[0037] 1. This wearable intraocular pressure measurement device features a sliding plate that moves the manometer horizontally. The sliding plate, in conjunction with a calibration mechanism and a measurement mechanism, controls the manometer's alignment with the user's left or right eye to complete the measurement. Existing devices often require users to repeatedly disassemble and reassemble the manometer to align it with their left or right eye, which is cumbersome and prone to user contact with the manometer and probe, leading to probe contamination. Therefore, this device solves these problems by using a sliding plate to control the manometer's movement. This sliding motion, combined with the calibration and measurement mechanisms, allows the manometer to slide to the position corresponding to the user's left or right eye, thus addressing the aforementioned issues.

[0038] 2. This wearable intraocular pressure measurement device uses a calibration mechanism and a locking assembly to mark the designated positions of the tonometers in both eyes of the user. Since the wearable frame and tonometer positions are difficult to fit all users, a sliding rod and a locking plate are incorporated to mark the corresponding positions of the user's eyes. These, along with a locking lever to position the sliding plate and tonometers, complete the marking of the measurement positions and the positioning of the tonometers, thus solving the aforementioned problem.

[0039] 3. This wearable intraocular pressure measurement device, through the setting of a measurement mechanism and a calibration mechanism, can mark and quickly locate the position of the user's eyes. The horizontal movement of the sliding plate and the fixing and switching of the locking components avoid the cumbersome operation and probe contamination problems caused by repeatedly disassembling and installing the pressure gauge. Furthermore, when the user adjusts the position of the pressure gauge, the pressure gauge is located within the outer cylinder and frame, preventing the user from touching the pressure gauge or probe during the adjustment process.

[0040] 4. This wearable intraocular pressure measurement device incorporates a contact component for rapid disinfection of the pressure measuring end. When users use the device themselves, they may blink and touch the pressure measuring end. Therefore, a fixing ring, an internal ring, and a moisture-absorbing ring are included to temporarily disinfect the pressure measuring end, preventing eye infections caused by user contact.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0053] like Figures 1-10 As shown, the present invention provides a technical solution: a wearable intraocular pressure measurement device, which is described below.

[0054] Including the wearable frame 1, it also includes:

[0055] The connecting strap 2 is installed on the outside of the wearable frame 1;

[0056] A detachable mounting frame 3 is attached to the wearable frame 1;

[0057] The calibration mechanism 4 is set on the wearable frame 1. The calibration mechanism 4 includes a slide plate 402 slidably connected inside the wearable frame 1 and a first adjusting rod 403 installed on the slide plate 402. The slide plate 402 has a through groove inside, and the first adjusting rod 403 is set as a rod whose length can be manually adjusted.

[0058] A measuring mechanism 5 is installed at the end of the first adjusting rod 403 away from the slide plate 402. The measuring mechanism 5 includes an outer frame 501 connected to the first adjusting rod 403 and a pressure gauge 507 disposed inside the outer frame 501. The slide plate 402 is used to drive the first adjusting rod 403, the outer frame 501 and the pressure gauge 507 to move in the horizontal direction.

[0059] When using the device, the user places the wear frame 1 on their forehead and puts on the connecting strap 2 on their head. A medical professional adjusts the calibration mechanism 4 and the measuring mechanism 5 for the user, thereby adjusting the pressure gauge 507 to the designated position for eye pressure measurement. In subsequent pressure measurements, the user adjusts the calibration mechanism 4 and the measuring mechanism 5 to adjust the pressure gauge 507 to the designated position for each eye.

[0060] By incorporating a sliding plate 402 that allows the pressure gauge 507 to move horizontally, the sliding plate 402, in conjunction with the calibration mechanism 4 and the measuring mechanism 5, controls the alignment of the pressure gauge 507 with the user's left or right eye to complete the pressure measurement. In existing devices, users often need to repeatedly disassemble and reassemble the pressure gauge 507 to align it with their left or right eye, which is cumbersome and prone to contamination due to user contact with the gauge and probe. Therefore, this device solves these problems by using a sliding plate 402 to control the movement of the pressure gauge 507, which, in conjunction with the calibration mechanism 4 and the measuring mechanism 5, allows the pressure gauge 507 to slide to a position corresponding to the user's left or right eye.

[0061] Calibration mechanism 4 also includes:

[0062] Vertical plate 401 is set on the wearable frame 1;

[0063] A first through slot 404 and a second through slot 405 are provided inside the wearable frame 1, and a plurality of the first through slot 404 and the second through slot 405 are provided.

[0064] A first telescopic rod 406 and a locking assembly 407 connected to the telescopic end of the first telescopic rod 406 are installed on the outside of the vertical plate 401.

[0065] The card slot component 407 includes:

[0066] The limiting cylinder 4071 is installed on the telescopic end of the first telescopic rod 406;

[0067] A sliding rod 4072 is slidably connected inside the limiting cylinder 4071, and a locking plate 4079 is installed below the sliding rod 4072. The locking plate 4079 is adapted to the first through groove 404.

[0068] The base plate 4073 is located above the sliding rod 4072;

[0069] A center rod 4074 is mounted on a base plate 4073 and a top plate 4075 is disposed above the center rod 4074. The top plate 4075 is made of magnetic material.

[0070] A sliding plate 4076 is slidably connected to the outside of the central rod 4074, and a washer 4078 is provided on the sliding plate 4076. The washer 4078 is made of magnetic material.

[0071] The locking rod 4077 is installed below the sliding plate 4076 and is adapted to the second through slot 405.

[0072] The working process of using calibration mechanism 4 to define the position of slide plate 402:

[0073] In the initial state, the gasket 4078 is magnetically engaged and fixed to the top plate 4075, and the locking rod 4077 is not in the second through slot 405. The slide plate 402 can slide freely within the wear frame 1. Medical personnel adjust the position of the pressure gauge 507 relative to the designated position for measuring the left and right eyes by adjusting the position of the measuring mechanism 5 and the slide plate 402. As the slide plate 402 moves to the designated position, the top plate 4075 is manually lifted. The top plate 4075 drives the center rod 4074, the bottom plate 4073, and the sliding rod 4072 to move upward as a whole. The top plate 4075 is then manually pulled to the slide plate 402, at which point the first telescopic rod 406 undergoes a corresponding extension and retraction. The top plate 4075 and sliding plate 4076 are pressed down. The top plate 4075 causes the center rod 4074, bottom plate 4073, sliding rod 4072, sliding plate 4076, and locking rod 4077 to move downward as a whole. The locking plate 4079, located below the sliding rod 4072, engages in the first through slot 404, and the locking rod 4077, located below the sliding plate 4076, engages in the second through slot 405. The locking rod 4077 then enters the channel of the slide plate 402, limiting the position of the slide plate 402. At this time, the positions of the slide plate 402 and the pressure gauge 507 are limited. The marked positions of the sliding rods 4072 and the locking plate 4079 on both sides are the designated positions of the pressure gauge 507 for the user's eyes.

[0074] The user then uses measuring mechanism 5 to adjust the specific position of pressure gauge 507 and perform pressure measurement.

[0075] The working process of using calibration mechanism 4 in conjunction with slide plate 402 for movement and fixation:

[0076] When it is necessary to measure the pressure of the user's other eye, lift the sliding plate 4076. The pad 4078 on the sliding plate 4076 will be attracted and fixed to the top plate 4075. The locking rod 4077 will disengage from the second through slot 405. The user manually adjusts the measuring mechanism 5 and the slide plate 402 until the slide plate 402 moves to the designated position of the pressure gauge 507 of the other eye. Then, press down the corresponding sliding plate 4076. The locking rod 4077 under the sliding plate 4076 will be locked into the channel of the slide plate 402, completing the fixation of the slide plate 402. Then, the user can complete the pressure measurement of the other eye by adjusting the measuring mechanism 5.

[0077] By setting up the calibration mechanism 4 and the positioning component 407, the designated positions of the user's eye pressure gauges 507 are marked. Since the wearing frame 1 and the position of the pressure gauges 507 are difficult to fit all users, a sliding rod 4072 and a positioning plate 4079 are provided to mark the corresponding positions of the user's eyes. Together with the positioning rod 4077 that positions the sliding plate 402 and the pressure gauges 507, the work of marking the measurement positions and positioning the pressure gauges 507 is completed, thus solving the aforementioned problem.

[0078] Measuring mechanism 5 also includes:

[0079] The second telescopic rod 505 is installed on the outer frame 501, and a suction cup is installed on the outside of the second telescopic rod 505;

[0080] A retaining ring 503 disposed inside the outer frame 501 and a contact component 504 disposed inside the retaining ring 503;

[0081] The lifting rod 506 is installed inside the outer frame 501 and is configured as an electric push rod.

[0082] The outer cylinder 502 is installed on the telescopic end of the lifting rod 506, and the pressure gauge 507 is slidably connected to the inside of the outer cylinder 502;

[0083] The second adjusting rod 508 is installed on the pressure gauge 507 and passes through the outer cylinder 502.

[0084] The process of adjusting the position of the manometer 507 using the measuring mechanism 5:

[0085] When medical staff adjust the position of the pressure gauge 507, they first activate the lifting rod 506 to the corresponding stroke. The lifting rod 506 drives the outer cylinder 502 and the pressure gauge 507 to move downwards until the pressure gauge 507 is at the height corresponding to the user's eyes. Then, the medical staff manually move the positions of the outer frame 501, the first adjusting rod 403, and the sliding plate 402 until the pressure gauge 507 corresponds to the user's eye position. This method completes the calibration of the user's eyes at the designated position.

[0086] Subsequently, after fixing the skateboard 402 to the designated positions for both eyes, the pressure gauge 507 is activated to complete the pressure measurement of the user's eyes. With the skateboard 402 in place, the user can manually pull the second telescopic rod 505. The suction cup on the outside of the second telescopic rod 505 is attracted and fixed in the mounting frame 3 to strengthen the fixation of the skateboard 402.

[0087] When the user operates the pressure measurement work, after the pressure gauge 507 is in the designated pressure measurement position, the stroke of the lifting rod 506 is adjusted to release the pressure gauge 507 for pressure measurement.

[0088] By setting up the measuring mechanism 5 and the calibration mechanism 4, the system can mark and quickly locate the position based on the user's eye position. The horizontal movement of the slide plate 402 and the fixing and switching of the locking component 407 avoid the cumbersome operation and probe contamination problems caused by repeatedly disassembling and installing the pressure gauge 507. Furthermore, when the user adjusts the position of the pressure gauge 507, it remains within the outer cylinder 502 and the outer frame 501, preventing the user from touching the pressure gauge 507 or the probe during adjustment.

[0089] Contact component 504 includes:

[0090] A connecting pipe 5041 is installed outside the fixing ring 503, and a plug is installed inside the connecting pipe 5041;

[0091] A first chamber 5045 and a second chamber 5046 are formed inside the fixing ring 503, and the first chamber 5045 and the second chamber 5046 are connected through multiple round holes;

[0092] An inner ring 5044 is set inside the fixed ring 503. The second chamber 5046 is located between the fixed ring 503 and the inner ring 5044. The inner concave surface of the inner ring 5044 is made of lint-free cloth, and the edge of the inner ring 5044 is made of rubber.

[0093] A sliding ring 5042 is slidably connected inside the fixed ring 503. The sliding ring 5042 is slidably connected in the first chamber 5045, and the sliding ring 5042 is connected to the first chamber 5045 through a third telescopic rod.

[0094] A moisture-absorbing ring 5043 is disposed inside the sliding ring 5042. The moisture-absorbing ring 5043 is made of moisture-absorbing material, and the inner diameter of the moisture-absorbing ring 5043 is slightly larger than the inner diameter of the built-in ring 5044.

[0095] The process of using contact component 504 to quickly disinfect the pressure measuring end of manometer 507:

[0096] The back panel of the outer frame 501 is manually removed. The user then manually adjusts the stroke of the second adjusting rod 508. The second adjusting rod 508 drives the pressure gauge 507 to slide inside the outer cylinder 502, thereby controlling the pressure measuring end of the pressure gauge 507 to enter the fixed ring 503 through the moisture-absorbing ring 5043, but not into the inner ring 5044. As the pressure gauge 507 moves, it compresses the moisture-absorbing ring 5043. The moisture-absorbing ring 5043 and the sliding ring 5042 begin to compress the third telescopic rod, thereby promoting the disinfectant liquid in the first chamber 5045 to enter the second chamber 5046 through the round hole, thus wetting the lint-free cloth. The stroke of the second adjusting rod 508 is further adjusted, and the wet lint-free cloth contacts the outer surface of the pressure measuring end of the pressure gauge 507 for rapid disinfection. The user then manually reverses the stroke of the second adjusting rod 508, causing the pressure measuring end of the pressure gauge 507 to stop at the moisture-absorbing ring 5043, allowing the measuring end to dry.

[0097] The contact component 504 is used to quickly disinfect the pressure measuring end of the pressure gauge 507. When a user uses the pressure gauge 507, there is a risk that the user may blink and touch the pressure measuring end of the pressure gauge 507 or touch it with their hand. In this case, it is necessary to quickly disinfect the pressure measuring end of the pressure gauge 507. Therefore, a fixing ring 503, an internal ring 5044, and a moisture-absorbing ring 5043 are set up to temporarily disinfect the pressure measuring end and avoid eye infections caused by the user touching the test end.

[0098] Working principle: When using the device, the user places the wearing frame 1 on their forehead and puts the connecting strap 2 on their head.

[0099] In the initial state, the gasket 4078 is magnetically engaged and fixed to the top plate 4075, and the locking rod 4077 is not in the second through slot 405. The slide plate 402 can slide freely within the wear frame 1.

[0100] When medical staff adjust the position of the pressure gauge 507, they first activate the lifting rod 506 to the corresponding stroke. The lifting rod 506 drives the outer cylinder 502 and the pressure gauge 507 to move downwards until the pressure gauge 507 is at the height corresponding to the user's eyes. Then, the medical staff manually move the positions of the outer frame 501, the first adjusting rod 403, and the sliding plate 402 until the pressure gauge 507 corresponds to the user's eye position. As the sliding plate 402 moves to the designated position, the top plate 4075 is manually lifted. The top plate 4075 drives the center rod 4074, the bottom plate 4073, and the sliding rod 4072 to move upwards as a whole. The top plate 4075 is then manually pulled to the sliding plate 402, at which point the first telescopic rod 406 undergoes a corresponding extension and retraction. The top plate 4075 and sliding plate 4076 are pressed down. The top plate 4075 causes the center rod 4074, bottom plate 4073, sliding rod 4072, sliding plate 4076, and locking rod 4077 to move downward as a whole. The locking plate 4079, located below the sliding rod 4072, engages in the first through slot 404, and the locking rod 4077, located below the sliding plate 4076, engages in the second through slot 405. The locking rod 4077 then enters the channel of the slide plate 402, limiting the position of the slide plate 402. At this time, the positions of the slide plate 402 and the pressure gauge 507 are limited. The marked positions of the sliding rods 4072 and the locking plate 4079 on both sides are the designated positions of the pressure gauge 507 for the user's eyes.

[0101] Subsequently, after fixing the skateboard 402 to the designated positions for both eyes, the pressure gauge 507 is activated to complete the pressure measurement of the user's eyes.

[0102] In subsequent pressure measurement work, the user adjusts the calibration mechanism 4 and the measuring mechanism 5 to adjust the pressure gauge 507 to the designated position and perform binocular pressure measurement.

[0103] When it is necessary to measure the pressure of the user's other eye, lift the sliding plate 4076. The pad 4078 on the sliding plate 4076 will be attracted and fixed to the top plate 4075. The locking rod 4077 will disengage from the second through slot 405. The user manually adjusts the measuring mechanism 5 and the slide plate 402 until the slide plate 402 moves to the designated position of the pressure gauge 507 of the other eye. Then, press down the corresponding sliding plate 4076. The locking rod 4077 under the sliding plate 4076 will be locked into the channel of the slide plate 402, completing the fixation of the slide plate 402. Then, the user can repeat the pressure measurement by adjusting the measuring mechanism 5 to complete the pressure measurement of the other eye.
