It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0039] As mentioned in the background technology, most of the tonometers currently used are desktop air-puff tonometers and applanation tonometers. However, desktop air-puff tonometers and applanation tonometers are large in size, inconvenient to carry, and have high costs and poor convenience in use.

[0040] In response to the above technical problems, this embodiment provides an intraocular pressure detection device. Figure 1 : is a circuit structure diagram of an intraocular pressure detection device provided by an embodiment of the present invention, Figure 2 This is a schematic diagram of the structure of an intraocular pressure detection device provided by an embodiment of the present invention, with reference to Figure 1 and Figure 2The intraocular pressure detection device includes: a detection shell 100, a processing module 110, a first detection module 120, a second detection module 130 and a pressurizing module 140; the detection shell 100 includes a handheld part 101 and a detection part 102; the pressurizing module 140, the first detection module 120 and the second detection module 130 are located at the end of the detection part 102 away from the handheld part 101, and the end of the detection part 102 away from the handheld part 101 is used to be placed outside the eyeball of the subject when detecting the intraocular pressure of the subject; the processing module 110 is connected to the first detection module 120 and the second detection module 130 respectively, the first detection module 120 is used to be placed in the first eye part A1 of the subject's eye socket when detecting the intraocular pressure of the subject, and the second detection module 130 is used to The second eye A2 is placed in the eye socket when detecting the intraocular pressure of the subject; the first eye A1 is opposite to the second eye A2; the first detection module 120 is used to detect the pressure value of the first eye A1, and the second detection module 130 is used to detect the pressure value of the second eye A2; the processing module 110 is connected to the pressurizing module 140, and the pressurizing module 140 is used to be placed in the first eye of the subject when detecting the intraocular pressure of the subject; the processing module 110 is used to control the pressurizing module 140 to apply pressure to the first eye when the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value, and obtain the target eyeball pressure value detected by the second detection module 130 when the pressure applied by the pressurizing module 140 reaches the preset value.

[0041] The processing module 110 includes, for example, a microprocessor integrated circuit chip, such as EFM32ZG110F32-QFN24 / STM32MP157AAA3 or other 32-bit microprocessor integrated circuit chips. The first detection module 120 and the second detection module 130 include, for example, pressure-sensitive sensors, such as RP-S5-5T or other thin-film flexible pressure sensors. When there is no pressure, the resistance of the pressure-sensitive sensor approaches infinity. The smaller the resistance value output by the pressure-sensitive sensor, the greater the corresponding pressure value. When the resistance value of the pressure-sensitive sensor changes, the voltage value output by the pressure-sensitive sensor changes accordingly. Therefore, the corresponding pressure value can be determined based on the voltage value output by the pressure-sensitive sensor. The detection housing 100 is made of ABS reinforced material injection molding and is designed in the shape of a razor. The pressurizing module 140, the processing module 110, the first detection module 120 and the second detection module 130 are all located inside or on the detection shell 100, which greatly reduces the volume and cost of the intraocular pressure detection device. The intraocular pressure detection device can be held by the handheld part 101 for intraocular pressure detection, thereby improving the convenience of the intraocular pressure detection device.

[0042] Specifically, intraocular pressure refers to the intraocular pressure value. When the intraocular pressure value of a subject needs to be measured, the subject holds the handheld unit 101 and places the end of the detection unit 102 away from the handheld unit 101 outside the subject's eyeball. Thus, the first detection module 120 and the pressurizing module 140 are placed in the first eye part A1 of the subject's eye socket, for example, the upper eye socket, and the second detection module 130 is placed in the second eye part A2 of the subject's eye socket, for example, the lower eye socket. Slowly push the detection part 102 into the eye socket, that is, push the first detection module 120 and the second detection module 130. At this time, the first detection module 120 and the second detection module 130 are simultaneously subjected to thrust and eyeball pressure, and the processing module 110 can obtain the current pressure values of the first detection module 120 and the second detection module 130. When the current pressure values obtained from the first detection module 120 and the second detection module 130 both reach the reference pressure value, it indicates that the pressures of the first eye A1 and the second eye A2 reach a balanced state. The processing module 110 performs correction and error elimination, and uses the reference pressure value as the zero point position of the pressure value, thereby eliminating the error caused by the eyelid thickness of different subjects and the thrust error of different subjects pushing the first detection module 120 and the second detection module 130, thereby achieving the effect of accurately detecting the eyeball pressure value. When the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value, the processing module 110 controls the pressurizing module 140 to apply pressure to the first eye. The first detection module 120 can detect the pressure applied by the pressurizing module 140 in real time. The processing module 110 controls the pressurizing module 140 to apply pressure according to the current pressure value detected by the first detection module 120, thereby increasing the pressure to a preset value. The pressurizing module 140 presses the eyeball downward. At this time, the second detection module 130 installed on the second eye measures the pressure variable of the eyeball (i.e., the eyeball pressure value) and converts it into a voltage value output. The processing module 110 converts the voltage value output by the second detection module 130 to obtain the target eyeball pressure value of the subject.

[0043] Furthermore, when the measured target eyeball pressure value is large, it indicates that the eyeball is enlarged and the surface is hard. Under the premise of constant downward thrust, the eyeball moves downward for a long distance, the eyeball measures a high surface pressure intensity, and a large resistance change rate, resulting in a large target eyeball pressure value. When the measured target eyeball pressure value is small, it indicates that the eyeball is soft and elastic. Under the premise of constant downward thrust, the eyeball moves downward for a short distance, the eyeball measures a low surface pressure intensity, and the resistance change rate is low, resulting in a small target eyeball pressure value. Therefore, the obtained target eyeball pressure value can be used to determine the eyeball condition of the subject. When the target eyeball pressure value is large, timely measures can be taken to facilitate timely detection and treatment.

[0044] The technical solution of this embodiment greatly reduces the size of the intraocular pressure detection device by arranging the pressurizing module, the processing module, the first detection module, and the second detection module inside or on the detection shell. The intraocular pressure detection device can be held by the handheld portion to perform intraocular pressure detection, thereby improving the convenience of the intraocular pressure detection device. When it is necessary to detect the eye pressure value of the subject, the subject holds the handheld portion, places the end of the detection module away from the handheld portion on the outside of the subject's eyeball, and slowly pushes the detection module into the eye socket. When the current pressure values obtained from the first detection module and the second detection module both reach the reference pressure value, it indicates that the pressure of the first eye and the second eye have reached a balanced state. The processing module performs correction and error elimination, using the reference pressure value as the zero point position of the pressure value, thereby eliminating the error caused by the eyelid thickness of different subjects and the thrust error of different subjects pushing the first detection module and the second detection module, thereby achieving the effect of accurately detecting the eye pressure value. The processing module controls the pressurizing module to apply pressure to the first eye to a preset value. The pressurizing module compresses the eyeball downward. At this point, a second detection module installed in the second eye measures the eyeball pressure variable and converts it into a voltage value for output. The processing module converts the voltage value output by the second detection module to obtain the subject's target eyeball pressure value. The technical solution of this embodiment solves the problem of the large size and poor user convenience of desktop air-puffing tonometers and applanation tonometers, improves the convenience of the intraocular pressure detection device, and enhances the accuracy of intraocular pressure detection.

[0045] As a further implementation of this embodiment, based on the above technical solution, Figure 3 is a circuit diagram of another intraocular pressure detection device provided by an embodiment of the present invention. Figure 4 This is a structural diagram of another intraocular pressure detection device provided by an embodiment of the present invention. Optionally, refer to Figure 3 and Figure 4 The pressurizing module 140 includes a pressurizing pump 141 and an airbag 142; the airbag 142 is used to be placed on the first eye A1 of the subject when detecting the intraocular pressure of the subject; the processing module 110 is connected to the pressurizing pump 141, and the pressurizing pump 141 is connected to the airbag 142. The processing module 110 is used to control the pressurizing pump 141 to inflate the airbag 142 when the current pressure values detected by the first detection module 120 and the second detection module 130 reach the reference pressure value, so that the airbag 142 applies pressure to the first eye.

[0046] Specifically, the pressure pump 141 uses a miniature air pressure pump of MINI-PUMP3-5V with an air pressure of 30KPa or other models, which is installed inside the detection shell 100. The inflation port of the pressure pump 141 is connected to the air inlet port of the airbag 142, and the air inlet port of the pressure pump 141 is suspended in the air and connected to the atmosphere. When the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value, the processing module 110 controls the pressure pump 141 to pressurize the airbag 142 and inflate the airbag 142 so that the airbag 142 applies pressure to the first eye A1. The processing module 110 controls the pressure pump 141 to pressurize according to the current pressure value detected by the first detection module 120, thereby pressurizing to a preset value. The airbag 142 presses the eyeball downward. At this time, the second detection module 130 installed on the second eye A2 measures the pressure variable of the eyeball (i.e., the eyeball pressure value) and converts it into a voltage value output. The processing module 110 converts the voltage value output by the second detection module 130 to obtain the target eyeball pressure value of the subject.

[0047] Optionally, refer to Figure 4 The detection part 102 includes a first pressing part 1021 and a second pressing part 1022; the airbag 142 and the first detection module 120 are arranged on the first pressing part 1021, and the second detection module 130 is arranged on the second pressing part 1022. The distance between the first pressing part 1021 and the second pressing part 1022 is within a preset distance range.

[0048] Specifically, the first pressing portion 1021 and the second pressing portion 1022 are bent into a forked shape and mounted on the side of the upper portion of the detection housing 100. When it is necessary to detect the eyeball pressure value of the subject, the subject holds the handheld portion 101, places the first pressing portion 1021 on the first eye portion A1 of the eye socket, and places the second pressing portion 1022 on the second eye portion A2 of the eye socket, thereby placing the first detection module 120 and the pressurizing module 140 on the first eye portion A1 of the subject's eye socket, and placing the second detection module 130 on the second eye portion A2 of the subject's eye socket. The first pressing part 1021 and the second pressing part 1022 are slowly pushed into the eye socket. At this time, the first detection module 120 and the second detection module 130 are simultaneously subjected to thrust and eyeball pressure. When the current pressure values obtained by the processing module 110 from the first detection module 120 and the second detection module 130 reach the reference pressure value, it indicates that the pressures of the first eye A1 and the second eye A2 have reached a balanced state. The processing module 110 performs correction and error elimination, and uses the reference pressure value as the zero point position of the pressure value, thereby eliminating the error caused by the eyelid thickness of different subjects and the thrust error of different subjects pushing the first detection module 120 and the second detection module 130, thereby achieving the effect of accurately detecting the eyeball pressure value. Then, the processing module 110 controls the pressure pump 141 to pressurize the airbag 142 and inflate the airbag 142, so that the airbag 142 applies pressure to the first eye A1, thereby pressurizing it to a preset value. The airbag 142 presses the eyeball downward. At this time, the second detection module 130 installed on the second eye A2 measures the pressure variable of the eyeball (i.e., the eyeball pressure value) and converts it into a voltage value output. The processing module 110 converts the voltage value output by the second detection module 130 to obtain the target eyeball pressure value of the subject.

[0049] Moreover, the preset distance range is, for example, the distance from the upper orbit to the lower orbit of most human eyes. By keeping the distance between the first pressing portion 1021 and the second pressing portion 1022 within the preset distance range, the intraocular pressure detection device can meet the needs of most human eyes.

[0050] Optionally, refer to Figure 3 and Figure 4 The intraocular pressure detection device also includes a voice module 151; the processing module 110 is connected to the voice module 151, and the processing module 110 is used to control the voice module 151 to issue a first prompt message when the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value; the processing module 110 is also used to control the voice module to issue a second prompt message when the current pressure value detected by the first detection module 120 or the second detection module 130 is greater than the first pressure threshold; the processing module 110 is also used to send the target eyeball pressure value to the voice module 151, so that the voice module 141 plays the target eyeball pressure value.

[0051] Specifically, the voice module 151 includes, for example, a digital voice chip circuit or other types of voice prompt circuits, and may further include a speaker. The voice module 151 is installed in the detection housing 100. When it is necessary to detect the eyeball pressure value of the subject, the subject holds the handheld portion 101, places the first pressing portion 1021 on the first eye portion A1 of the eye socket, and places the second pressing portion 1022 on the second eye portion A2 of the eye socket, thereby placing the first detection module 120 and the pressurizing module 140 on the first eye portion A1 of the subject's eye socket, and placing the second detection module 130 on the second eye portion A2 of the subject's eye socket. The first pressing part 1021 and the second pressing part 1022 are slowly pushed into the eye socket. At this time, the first detection module 120 and the second detection module 130 are simultaneously subjected to the thrust and the pressure of the eyeball. When the current pressure values obtained by the processing module 110 from the first detection module 120 and the second detection module 130 reach the reference pressure value, it indicates that the pressures of the first eye A1 and the second eye A2 have reached a balanced state. The processing module 110 controls the voice module 151 to issue a first prompt message, such as a voice prompt such as "Start measuring, do not move", to prompt the subject to start the measurement, do not shake, and stay stable, thereby ensuring the accuracy of the measurement.

[0052] If the current pressure value detected by the first detection module 120 or the second detection module 130 is greater than the first pressure threshold, it indicates that the subject pushes the first pressing part 1021 and the second pressing part 1022 with greater force. The processing module 110 controls the voice module to issue a second prompt message, such as a voice prompt such as "Please reposition it", so that the subject can correct the posture and re-place the intraocular pressure detection device correctly in the eye socket to facilitate intraocular pressure measurement.

[0053] After the processing module 110 obtains the target eye pressure value of the subject, it sends the target eye pressure value to the voice module 151. The voice module 151 broadcasts the target eye pressure value, so that the subject can know the measured target eye pressure value in time, realizing the subject's self-service intraocular pressure detection, and further improving the convenience of the intraocular pressure testing device.

[0054] Optionally, refer to Figure 3 and Figure 4The intraocular pressure detection device also includes an indication module 152; the indication module includes a first indicator light D1, a second indicator light D2 and a third indicator light D3; the luminous colors of the first indicator light D1, the second indicator light D2 and the third indicator light D3 are different; the processing module 110 is connected to the first indicator light D1, and the processing module 110 is used to control the first indicator light D1 to illuminate when the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value; the processing module 110 is connected to the second indicator light D2, and the processing module 110 is also used to control the second indicator light D2 to illuminate when the pressurizing module 140 applies pressure to the first eye A1; the processing module 110 is connected to the third indicator light D3, and the processing module 110 is also used to control the third indicator light D3 to illuminate when the current pressure value detected by the first detection module 120 or the second detection module 130 is greater than the first pressure threshold.

[0055] Specifically, the first indicator D1 is, for example, a green indicator. When the current pressure values obtained by the processing module 110 from the first detection module 120 and the second detection module 130 both reach the reference pressure value, indicating that the pressures in the first eye A1 and the second eye A2 have reached equilibrium, the processing module 110 controls the first indicator D1 to illuminate, prompting the subject to begin measurement and to remain stable without shaking, thereby ensuring measurement accuracy. The second indicator D2 is, for example, a yellow indicator. When the pressurizing module 140 applies pressure to the first eye A1, the processing module 110 controls the second indicator D2 to illuminate, prompting the subject to be measured. The third indicator light D3 is, for example, a red indicator light. If the current pressure value detected by the first detection module 120 or the second detection module 130 is greater than the first pressure threshold, indicating that the force applied by the subject to push the first pressing portion 1021 and the second pressing portion 1022 is relatively large, the processing module 110 controls the third indicator light D3 to illuminate, prompting the subject to correctly re-place the intraocular pressure detection device in the eye socket until the reference pressure is appropriate and the first indicator light D1 is illuminated, thereby restarting intraocular pressure measurement and facilitating intraocular pressure measurement. The first indicator light D1, the second indicator light D2, and the third indicator light D3 are, for example, arranged in a straight line on the detection housing 100.

[0056] For example, Figure 3As shown, the anodes of the first indicator light D1, the second indicator light D2 and the third indicator light D3 are connected to the first power supply V1, the cathode of the first indicator light D1 is connected to the processing module 110, the cathode of the second indicator light D2 is connected to the processing module 110 through the first diode D4, and the cathode of the third indicator light D3 is connected to the processing module 110 through the second diode D5 and the first diode D4. Therefore, when the processing module 110 outputs different voltages, different indicator lights can be lit, so that when the current pressure values obtained by the first detection module 120 and the second detection module 130 reach the reference pressure value, the processing module 110 controls the first indicator light D1 to light up; when the pressurizing module 140 applies pressure to the first eye A1, the processing module 110 controls the second indicator light D2 to light up; when the current pressure value detected by the first detection module 120 or the second detection module 130 is greater than the first pressure threshold, the processing module 110 controls the third indicator light D3 to light up.

[0057] Optionally, refer to Figure 3 and Figure 4 The intraocular pressure detection device also includes a display module 153; the processing module 110 is connected to the display module 153, and the processing module 110 is used to send the target eye pressure value to the display module 153, so that the display module 153 displays the target eye pressure value.

[0058] Specifically, the display module 153 includes, for example, a liquid crystal display (LCD) that displays the intraocular pressure value using a three-digit digital segment display with an accompanying battery indicator icon. The LCD screen includes a built-in codec signal conversion circuit on the back, which facilitates converting the received digital signal corresponding to the target intraocular pressure value into an analog signal, thereby visually displaying the target intraocular pressure value and further improving the convenience of the intraocular pressure testing device. The display module 153 is located on the detection housing 100, with the screen of the display module 153 exposed outside the detection housing 100, facilitating the display of the target intraocular pressure value.

[0059] Optionally, refer to Figure 3 and Figure 4 The intraocular pressure detection device also includes an air release valve 154; the processing module 110 is connected to the air release valve 154, and the processing module 110 is used to control the air release valve 154 to open after obtaining the target eyeball pressure value detected by the second detection module 130, so as to deflate the pressurization module 140.

[0060] Specifically, deflation valve 154, such as a JS0520L or other miniature one-way deflation valve, is installed inside the front end of detection housing 100. The inlet port of deflation valve 154 is connected to the inflation port of pressure pump 141 and the inlet port of airbag 142. The exhaust port of deflation valve 154 is suspended in the air and vented to the atmosphere, allowing the exhaust gas to be directly dissipated into the surrounding air. When processing module 110 obtains the target eyeball pressure value, processing module 110 controls deflation valve 154 to open, causing pressure module 140 to deflate, that is, airbag 142 to deflate, completing the detection.

[0061] Optionally, refer to Figure 3 and Figure 4 The intraocular pressure detection device also includes a power supply module 155 and a trigger module 156; the power supply module 155 is connected to the power supply end of the processing module 110 through the trigger module 156, and the power supply module 155 is used to power the processing module 110 when the trigger module 156 is turned on.

[0062] Specifically, the trigger module 156 includes, for example, a trigger button, which is, for example, a capacitive touch switch button. When it is necessary to detect intraocular pressure, the trigger module 156 is triggered, the trigger module 156 is turned on, and the power module 155 supplies power to the processing module 110 through the trigger module 156, waking up the processing module 110, so that the processing module 110 starts to collect the current pressure values of the first detection module 120 and the second detection module 130. When the current pressure values of the first detection module 120 and the second detection module 130 both reach the reference pressure value, the processing module 110 controls the pressure pump 141 to inflate the airbag 142, so that the airbag 142 pressurizes the first eye. When the pressure reaches the preset value, the processing module 110 obtains the target eyeball pressure value from the second detection module 130, thereby completing the intraocular pressure detection.

[0065] On the basis of the above technical solutions, optionally, continue to refer to Figure 3The power module 155 includes a battery 1551, a charging socket 1552 and a charging circuit 1553; the first pole of the battery 1551 is grounded, the second pole of the battery 1551 is connected to the power end of the processing module 110 through the trigger module 156, and the charging socket 1552 is connected to the second pole of the battery 1551 through the charging circuit 1553.

[0066] Specifically, battery 1551 is, for example, a lithium battery, such as a 3.7V 500mA polymer lithium-ion battery. Charging port 1552 is, for example, an internationally standard V8-5P charging port. Charging circuit 1553 is, for example, a conventional TP4057 or other type of lithium battery intelligent management circuit chip. By providing charging port 1552 and charging circuit 1553, charging can be performed even when the battery 1551 is low, further enhancing the convenience of the intraocular pressure detection device.

By welding the components on the circuit substrate 158 and installing the circuit substrate 158 inside the detection shell 100, it is convenient to set all the devices inside the detection shell 100, facilitate assembly of the intraocular pressure detection device, and help reduce the volume and cost of the intraocular pressure detection device and improve the convenience of the intraocular pressure detection device.

[0068] The technical solution of this embodiment also provides an intraocular pressure detection method, which is performed by the intraocular pressure detection device provided by any of the above embodiments. Figure 5 This is a flow chart of an intraocular pressure detection method provided by an embodiment of the present invention, with reference to Figure 5 , IOP detection methods include:

[0069] S210: When the current pressure values detected by the first detection module and the second detection module both reach a reference pressure value, the processing module controls the pressurizing module to apply pressure to the first eye of the subject.

[0070] Specifically, refer to Figure 1 and Figure 2When it is necessary to detect the eye pressure value of the subject, the subject holds the handheld part 101 and places the end of the detection part 102 away from the handheld part 101 outside the subject's eyeball, so that the first detection module 120 and the pressurizing module 140 are placed in the first eye part A1 of the subject's eye socket, for example, the upper eye socket, and the second detection module 130 is placed in the second eye part A2 of the subject's eye socket, for example, the lower eye socket. Slowly push the detection part 102 into the eye socket, that is, push the first detection module 120 and the second detection module 130. At this time, the first detection module 120 and the second detection module 130 are simultaneously subjected to thrust and eyeball pressure, and the processing module 110 can obtain the current pressure values of the first detection module 120 and the second detection module 130. When the current pressure values obtained from the first detection module 120 and the second detection module 130 both reach the reference pressure value, it indicates that the pressures of the first eye A1 and the second eye A2 reach a balanced state. The processing module 110 performs correction and error elimination, and uses the reference pressure value as the zero point position of the pressure value, thereby eliminating the error caused by the eyelid thickness of different subjects and the thrust error of different subjects pushing the first detection module 120 and the second detection module 130, thereby achieving the effect of accurately detecting the eyeball pressure value. When the current pressure values detected by the first detection module 120 and the second detection module 130 both reach the reference pressure value, the processing module 110 controls the pressurizing module 140 to apply pressure to the first eye. The first detection module 120 can detect the pressure applied by the pressurizing module 140 in real time. The processing module 110 controls the pressurizing module 140 to apply pressure according to the current pressure value detected by the first detection module 120, that is, to apply pressure to the first eye A1.

[0071] S220: When the pressure applied by the pressurizing module reaches a preset value, the processing module obtains the target eyeball pressure value detected by the second detecting module.

[0072] Specifically, the processing module 110 controls the pressurizing module 140 to pressurize according to the current pressure value detected by the first detection module 120, thereby increasing the pressure to a preset value. The pressurizing module 140 presses the eyeball downward. At this time, the second detection module 130 installed on the second eye measures the pressure variable of the eyeball (i.e., the eyeball pressure value), converts it into a voltage value output, and the processing module 110 converts the voltage value output by the second detection module 130 to obtain the target eyeball pressure value of the subject. In addition, by arranging the pressurizing module 140, the processing module 110, the first detection module 120 and the second detection module 130 inside the detection housing 100 or on the detection housing 100, the volume of the intraocular pressure detection device is greatly reduced, and the intraocular pressure detection device can be held by the handheld portion 101 for intraocular pressure detection, thereby improving the convenience of the intraocular pressure detection device.

[0073] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved. This is not limited herein.

Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
