Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a wearable intraocular pressure monitoring device. Background Art

[0002] Intraocular pressure monitoring is an important means for diagnosing and managing ophthalmic diseases such as glaucoma. Traditional intraocular pressure measurement methods mainly include contact and non-contact methods. Contact measurement usually uses devices such as Goldmann applanation tonometer or Tono-Pen, while non-contact measurement usually uses a pneumatic tonometer.

[0003] Currently, intraocular pressure monitoring technology is an important part of the diagnosis and treatment of ophthalmic diseases. Traditional intraocular pressure measurement methods usually involve directly contacting the cornea with pneumatic or mechanical devices. These methods may cause discomfort to patients and may cause measurement errors in some cases. For example, single-point contact measurement may lead to inaccurate measurement results due to the asymmetry of the corneal shape or excessive local pressure. Although existing non-contact intraocular pressure measurement devices reduce patient discomfort, they may require patients to be in a specific posture for measurement and need to be operated by professionals in a hospital or clinic, which limits intraocular pressure monitoring in patients' daily lives. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides a wearable intraocular pressure monitoring device. The present invention uses the jet method to monitor the corneal pressure of patients. A branch-shaped air outlet pipe is provided at the output end of the micro fan. The air outlet of the air outlet pipe is aligned with the top ends on the left and right sides of a single eye of the patient after wearing the lens body, so as to distribute the pressure more evenly on the corneal surface, thereby reducing the measurement error that may be caused by excessive single-point pressure. At the same time, in cooperation with the intraocular pressure monitoring sensor inside the lens body, the corneal pressure of the patient can be monitored, and the monitored data is transmitted to the signal processing unit inside the middle hollow shell above the front end of the lens body, and then controlled by the main controller in the same hollow shell. The data is sent to the terminal through the wireless transmission units on the left and right sides of the front end face of the lens body, which is convenient for patients and doctors to remotely view and analyze the data, improving the convenience of monitoring.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the present invention provides the following technical solution: A wearable intraocular pressure monitoring device, including a lens body, the rear of the top ends on both left and right sides of the lens body are rotatably connected with counterweight temple arms, a silica gel layer is fixedly connected to the outer side of the counterweight temple arms, a battery compartment is fixedly connected to the middle of the top of the lens body, micro fans are fixedly connected to both left and right sides of the top of the lens body, an air outlet pipe is fixedly connected to the output end of the micro fans, a monitoring compartment is opened on the rear end face of the lens body, an intraocular pressure monitoring sensor is fixedly connected to the lower side in the front of the lens body, a hollow shell is fixedly connected to the middle above the front end face of the lens body, a main controller is arranged on the left side inside the hollow shell, a signal processing unit is arranged on the right side inside the hollow shell, a wireless transmission unit is fixedly connected to the middle of both left and right sides of the front end face of the lens body, an LED light strip is fixedly connected to the rear edge inside the lens body, and an adhesive layer is arranged between the surface of the LED light strip and the rear edge inside the lens body. The wind blown out by the air outlet pipe can distribute the pressure more evenly on the corneal surface, thereby reducing the measurement error that may be caused by excessive single-point pressure, and facilitating the remote viewing and analysis of data by patients and doctors, improving the convenience of monitoring.

[0008] Preferably, the micro fans, the intraocular pressure monitoring sensor, the main controller, the signal processing unit, the wireless transmission unit, and the LED light strip are all electrically connected to the battery compartment, and the micro fans, the intraocular pressure monitoring sensor, the main controller, the signal processing unit, the wireless transmission unit, and the LED light strip are all connected to the battery compartment by wires.

[0009] Preferably, the main controller is electrically connected to the intraocular pressure monitoring sensor, the signal processing unit, and the wireless transmission unit, and the wireless transmission unit is wirelessly connected to the terminal through Bluetooth. It can supply power to electronic components such as the micro fans, the intraocular pressure monitoring sensor, the main controller, the signal processing unit, the wireless transmission unit, and the LED light strip that require electric energy to drive. A rechargeable battery is arranged in the battery compartment, and it can be detached from the charging wire after charging, improving the comfort of the patient's wearing to a certain extent.

[0010] Preferably, the intraocular pressure monitoring sensor is fixed at the front end position inside the monitoring compartment opened on the rear end face of the lens body. The number of monitoring compartments opened on the rear end face of the lens body is two groups, and the monitoring compartments are distributed on both left and right sides of the rear end face of the lens body. The number of intraocular pressure monitoring sensors in a single group of monitoring compartments on the rear end face of the lens body is two, and the intraocular pressure monitoring sensors are distributed at the lower left and right sides of the front end of a single group of monitoring compartments, which can monitor the two top ends of the patient's cornea, increasing the monitoring range, and at the same time avoiding the situation that the corneal shape of some people may not be completely symmetrical, resulting in deviation of subsequent results.

[0011] Preferably, the air outlet pipe is provided with two air outlet ends, and the end of the air outlet pipe away from the micro fan is fixed at the left and right positions above the front end face of the lens body. The number of the micro fans and the air outlet pipes is two groups. The micro fans are fixed at the top positions of the lens body near the left and right sides of the battery compartment, and the air outlet ends of the air outlet pipes away from the micro fans are fixed at the left and right sides above a single monitoring compartment. The air outlet of the air outlet pipe is aligned with the top ends of the left and right sides of a single eye after the patient wears the lens body, so as to distribute the pressure more evenly on the corneal surface, thereby reducing the measurement error that may be caused by excessive single-point pressure.

[0012] Preferably, the shape of the weighted temple is L-shaped, and the overall weight of the weighted temple is the same as the total weight of the lens body, the micro fan, the intraocular pressure monitoring sensor, the main controller, the signal processing unit, and the wireless transmission unit. The overall weight of the weighted temple is the same as the overall weight of the lens body, making it more stable and not easy to slide when worn, thereby improving the measurement accuracy.

[0013] Preferably, the silicone layer covers the surface of the weighted temple, and the thickness of the silicone layer covering the surface of the weighted temple is 2 mm. The material of the silicone layer is hydrogenated silicone rubber. The setting of the silicone layer not only provides a soft touch for the patient's skin, but also greatly reduces the skin indentation or allergy phenomenon that may be caused by long-term wearing due to its good elasticity and breathability.

[0014] Preferably, the overall shape of the LED light strip is U-shaped. LED lamp beads are arranged inside the LED light strip, and the distance between the LED lamp beads is 1.5 cm. The soft light design of the LED light strip can reduce the measurement error caused by insufficient light, ensuring the accuracy of the intraocular pressure monitoring data.

[0015] Preferably, through grooves communicating with each other are formed between the two monitoring compartments on the rear end face inside the lens body and at the bottom of the battery compartment. The wires arranged between the intraocular pressure monitoring sensor and the battery compartment and between the LED light strip and the battery compartment are all located in the through grooves. The induction of the wires can keep the monitoring compartment clean and tidy, and at the same time avoid the obstruction of the wires from preventing the intraocular pressure monitoring sensor from monitoring the corneal pressure of the patient.

[0016] Compared with the prior art, the present invention provides a wearable intraocular pressure monitoring device, having the following

[0017] Beneficial effects:

[0018] 1. Compared with the prior art, the present invention monitors the corneal pressure of patients by means of the jet method. A wind outlet pipe with branches is provided at the output end of the micro fan. The air outlets of the wind outlet pipe are aligned with the top ends on the left and right sides of a single eye after the patient wears the lens body, distributing the pressure more evenly on the corneal surface, thereby reducing the measurement error that may be caused by excessive single-point pressure. Moreover, since the shape of some people's corneas may not be completely symmetrical, the bilateral air outlet design can better adapt to this asymmetry, ensuring the accuracy of the measurement results. At the same time, in cooperation with the intraocular pressure monitoring sensor inside the lens body, it can monitor the corneal pressure of the patient and transmit the monitored data to the signal processing unit inside the middle hollow shell above the front end of the lens body, and then be controlled by the main controller also located in the hollow shell, and the data is sent to the terminal through the wireless transmission units on the left and right sides of the front end face of the lens body, facilitating remote viewing and analysis of the data by patients and doctors and improving the convenience of monitoring.

[0019] 2. Compared with the prior art, through the designed counterweight temple and silicone layer, the present invention avoids the overall weight of the lens body being too high, which not only affects the discomfort of the patient when wearing but also causes the problem of the lens body tilting forward. The overall weight of the counterweight temple is the same as that of the lens body, making it more stable and less likely to slide when worn, thereby improving the measurement accuracy. The setting of the silicone layer not only provides a soft touch for the patient's skin, but also its good elasticity and breathability greatly reduce the skin indentation or allergic phenomena that may be caused by long-term wearing.

[0020] 3. Compared with the prior art, the LED light strip designed in the present invention adopts a soft light design, which fully considers the irritation problem that may be caused to the eyes when performing intraocular pressure monitoring in low-light or dark environments. The soft light LED light strip can provide uniform and soft light, effectively avoiding the discomfort of the eyes caused by direct or reflected strong light, ensuring that patients can perform comfortable intraocular pressure measurement under any lighting conditions. At the same time, this soft light design can also reduce the measurement error caused by insufficient light, ensuring the accuracy of the intraocular pressure monitoring data.

[0039] Embodiment Two:

[0040] Please refer to Figure 1 、 Figure 2 and Figure 6 as shown:

[0041] On the rear sides of the tops of the left and right sides of the lens body 1, a counterweight temple 14 is connected through a rotating shaft. The outer side of the counterweight temple 14 is covered and fixed by a silica gel layer 2. The shape of the counterweight temple 14 is L-shaped, and the overall weight of the counterweight temple 14 is the same as the total weight of the lens body 1, the micro fan 4, the intraocular pressure monitoring sensor 9, the main controller 11, the signal processing unit 12, and the wireless transmission unit 7.

[0042] In this embodiment: The overall weight of the counterweight temple 14 is the same as the overall weight of the lens body 1, making it more stable and less likely to slide during wearing, thus improving the accuracy of measurement.

[0043] In an alternative embodiment: The silica gel layer 2 covers the surface of the counterweight temple 14, and the thickness of the silica gel layer 2 covering the surface of the counterweight temple 14 is 2 mm. The material of the silica gel layer 2 is hydrogenated silicone rubber.

[0045] Embodiment Three:

[0046] Please refer to Figure 2 and Figure 5 as shown: At the rear edge inside the lens body 1, an LED light strip 10 is connected through an adhesive layer 13. The overall shape of the LED light strip 10 is U-shaped. LED lamp beads are arranged inside the LED light strip 10, and the distance between the LED lamp beads is 1.5 cm.

[0047] In this embodiment: The soft light design of the LED light strip 10 can reduce the measurement error caused by insufficient light, ensuring the accuracy of the intraocular pressure monitoring data.

[0048] In an alternative embodiment: Through holes are provided in a penetrating manner between two groups of monitoring bins 8 on the rear end face inside the lens body 1 and at the bottom of the battery bin 3. The wires arranged between the intraocular pressure monitoring sensor 9 and the battery bin 3 and between the LED light strip 10 and the battery bin 3 are all located in the through holes.

[0049] In this embodiment: The arrangement of the wires can keep the inside of the monitoring bin 8 clean and tidy, and at the same time avoid the obstruction of the wires from preventing the intraocular pressure monitoring sensor 9 from monitoring the corneal pressure of the patient.
