The processing module 110 includes, for example, a microprocessor integrated circuit chip, such as an EFM32ZG110F32-QFN24/STM32MP157AAA3 or other type of 32-bit microprocessor integrated circuit chip. The first detection module 120 and the second detection module 130 include, for example, pressure-sensitive sensors, such as RP-S5-5T or other types of film-type flexible pressure sensors, where when no pressure exists, the resistance of the pressure-sensitive sensor approaches infinity, and the smaller the resistance value output by the pressure-sensitive sensor, the larger the corresponding pressure value; when the resistance value of the pressure-sensitive sensor changes, the voltage value output by the pressure-sensitive sensor correspondingly changes, so that the corresponding pressure value can be determined according to the voltage value output by the pressure-sensitive sensor. The detection housing 100 is made of ABS reinforced material by injection molding, and the shape is designed into a shaver shape. The pressurizing module 140, the processing module 110, the first detecting module 120 and the second detecting module 130 are all located inside the detecting housing 100 or on the detecting housing 100, so that the volume and cost of the intraocular pressure detecting device are greatly reduced, the intraocular pressure detecting device can be held by the hand-held part 101 for intraocular pressure detection, and convenience of the intraocular pressure detecting device is improved.

Specifically, intraocular pressure is an eyeball pressure value. When the eyeball pressure value of the subject needs to be detected, the subject holds the handheld portion 101, and places the end of the detecting portion 102 away from the handheld portion 101 outside the eyeball of the subject, so that the first detecting module 120 and the pressurizing module 140 are placed on the first eye portion A1 of the orbit of the subject, such as the upper orbit, and the second detecting module 130 is placed on the second eye portion A2 of the orbit of the subject, such as the lower orbit. The detection part 102 is slowly pushed into the eye socket, that is, the first detection module 120 and the second detection module 130 are pushed, at this time, the first detection module 120 and the second detection module 130 receive the thrust and the pressure of the eyeball at the same time, 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 reach the reference pressure value, it indicates that the pressure of the first eye A1 and the second eye A2 reach the equilibrium state, the processing module 110 corrects and eliminates errors, and uses the reference pressure value as the zero position of the pressure value, thereby eliminating errors caused by eyelid thicknesses of different testees, and thrust errors of the first detection module 120 and the second detection module 130 are pushed by different testees, 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 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 pressurize according to the current pressure value detected by the first detection module 120, so as to pressurize to a preset value, the pressurizing module 140 presses the eyeball to press down, at this time, the second detection module 130 installed on the second eye detects the pressure variable of the eyeball (namely, the eyeball pressure value), the pressure variable is converted into a voltage value to be output, and the processing module 110 converts the voltage value output by the second detection module 130, so that the target eyeball pressure value of the tested person can be obtained.

In addition, when the measured pressure value of the eyeball is larger, the eyeball bulge surface is hard, the downward moving distance of the eyeball is long under the precondition that the pushing thrust is unchanged, and the pressure intensity of the eyeball surface measured by the second detection module 130 is high and the resistance change rate is large, so that the obtained pressure value of the eyeball is large; the measured pressure value of the target eyeball is smaller, which indicates that the eyeball is soft and elastic, the downward moving distance of the eyeball is short under the precondition that the pushing force is unchanged, the pressure intensity of the surface of the eyeball measured by the second detection module 130 is low, the change rate of the measured resistance value is low, and the obtained pressure value of the target eyeball is smaller. Therefore, the eyeball state of the tested person can be determined through the obtained target eyeball pressure value, and measures can be taken in time when the target eyeball pressure value is larger, so that the method is beneficial to finding and treating in time.

According to the technical scheme, the pressurizing module, the processing module, the first detection module and the second detection module are arranged inside the detection shell or on the detection shell, so that the volume of the intraocular pressure detection device is greatly reduced, the intraocular pressure detection device can be held by the hand-held part for intraocular pressure detection, and the convenience of the intraocular pressure detection device is improved. When the eyeball pressure value of the tested person needs to be detected, the tested person holds the hand-held part, one end of the detection part, which is far away from the hand-held part, is placed outside the eyeball of the tested person, the detection part is slowly pushed into the eyebox, when the current pressure values acquired from the first detection module and the second detection module reach the reference pressure value, the pressure of the first eye and the second eye is indicated to reach an equilibrium state, the processing module corrects and eliminates errors, the reference pressure value is used as a zero position of the pressure value, and therefore errors caused by eyelid thicknesses of different tested persons are eliminated, and thrust errors of the first detection module and the second detection module are pushed by different tested persons, so that the effect of accurately detecting the eyeball pressure value is achieved. The processing module is used for controlling the pressurizing module to apply pressure to the first eye to a preset value, the pressurizing module presses the eyeball to press downwards, at the moment, the second detecting module arranged on the second eye is used for measuring the pressure variable of the eyeball and converting the pressure variable into a voltage value to be output, and the processing module is used for converting the voltage value output by the second detecting module to obtain the target eyeball pressure value of the tested person.

Specifically, the pressurizing PUMP 141 is a MINI air pressurizing PUMP with the MINI-PUMP3-5V air pressure of 30KPa specification or other types, and is installed in the detection housing 100, the air charging port of the pressurizing PUMP 141 is connected with the air inlet port of the air bag 142, and the air inlet port of the pressurizing PUMP 141 is suspended and communicated with the atmosphere. When the current pressure values detected by the first detection module 120 and the second detection module 130 reach the reference pressure value, the processing module 110 controls the pressurizing pump 141 to pressurize the air bag 142, and inflates the air bag 142, so that the air bag 142 applies pressure to the first eye A1, the processing module 110 controls the pressurizing pump 141 to pressurize according to the current pressure value detected by the first detection module 120, so as to pressurize to a preset value, the air bag 142 presses the eyeball to press down, at this time, the second detection module 130 mounted on the second eye A2 detects the pressure variable of the eyeball (namely the eyeball pressure value), the pressure variable is converted into a voltage value to be output, and the processing module 110 converts the voltage value output by the second detection module 130, so that the target eyeball pressure value of the tested person can be obtained.

Alternatively, referring to fig. 4, the detecting portion 102 includes a first pressing portion 1021 and a second pressing portion 1022; the airbag 142 and the first detection module 120 are disposed on the first pressing portion 1021, and the second detection module 130 is disposed on the second pressing portion 1022, with a distance between the first pressing portion 1021 and the second pressing portion 1022 being within a preset distance range.

Specifically, the first pressing portion 1021 and the second pressing portion 1022 are mounted on the side of the upper portion of the detection housing 100 in an interdigital shape. When the eyeball pressure value of the subject needs to be detected, the subject holds the hand-held portion 101, places the first pressing portion 1021 at the first eye portion A1 of the orbit, places the second pressing portion 1022 at the second eye portion A2 of the orbit, thereby placing the first detection module 120 and the pressing module 140 at the first eye portion A1 of the orbit of the subject, and places the second detection module 130 at the second eye portion A2 of the orbit of the subject. 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 receive the thrust and the eyeball pressure at the same time, 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, the pressure of the first eye A1 and the second eye A2 is indicated to reach an equilibrium state, the processing module 110 corrects and eliminates errors, the reference pressure value is used as a zero position of the pressure value, and therefore errors caused by eyelid thicknesses of different testees are eliminated, and the thrust errors of the first detection module 120 and the second detection module 130 are pushed by different testees, so that the effect of accurately detecting the eyeball pressure value is achieved. Then, the processing module 110 controls the pressurizing pump 141 to pressurize the air bag 142, and inflates the air bag 142, so that the air bag 142 applies pressure to the first eye A1, and the air bag 142 pressurizes the eyeball to a preset value, at this time, the second detecting module 130 mounted on the second eye A2 detects the pressure variable of the eyeball (i.e. the eyeball pressure value), and converts the pressure variable into a voltage value for output, and the processing module 110 converts the voltage value output by the second detecting module 130, so as to obtain the target eyeball pressure value of the tested person.

In addition, the preset distance range is, for example, the distance from the upper orbit to the lower orbit of most eyes, and the distance between the first pressing portion 1021 and the second pressing portion 1022 is within the preset distance range, so that the intraocular pressure detecting device can meet the requirement of most eyes.

Specifically, the voice module 151 includes, for example, a digital voice chip circuit or other type of voice prompt circuit, and may further include a speaker, and the voice module 151 is installed in the detection housing 100. When the eyeball pressure value of the subject needs to be detected, the subject holds the hand-held portion 101, places the first pressing portion 1021 at the first eye portion A1 of the orbit, places the second pressing portion 1022 at the second eye portion A2 of the orbit, thereby placing the first detection module 120 and the pressing module 140 at the first eye portion A1 of the orbit of the subject, and places the second detection module 130 at the second eye portion A2 of the orbit of the subject. The first pressing portion 1021 and the second pressing portion 1022 are slowly pushed into the eye socket, at this time, the first detecting module 120 and the second detecting module 130 receive the pushing force and the eyeball pressure at the same time, when the current pressure values obtained by the processing module 110 from the first detecting module 120 and the second detecting module 130 reach the reference pressure value, it is indicated that the pressures of the first eye A1 and the second eye A2 reach the equilibrium state, and the processing module 110 controls the voice module 151 to send out the first prompt information, for example, send out the voice prompts such as "start measurement, do not move", and prompt the measured person to start measurement, do not shake, and keep stable, thereby guaranteeing the accuracy of measurement.

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, which indicates that the force of the detected person pushing the first pressing portion 1021 and the second pressing portion 1022 is greater, the processing module 110 controls the voice module to send out a second prompt message, for example, a voice prompt such as "please replace", so that the detected person corrects the posture, and the intraocular pressure detection device is correctly placed in the eye socket again, thereby facilitating the intraocular pressure measurement.

After the processing module 110 obtains the target eyeball pressure value of the tested person, the target eyeball pressure value is sent to the voice module 151, and the voice module 151 broadcasts the target eyeball pressure value, so that the tested person can timely acquire the measured target eyeball pressure value, self-help intraocular pressure detection of the tested person is realized, and convenience of the intraocular pressure testing device is further improved.

Specifically, the first indicator light D1 is, for example, a green indicator light, when the current pressure values obtained by the processing module 110 from the first detecting module 120 and the second detecting module 130 reach the reference pressure value, which indicates that the pressures of the first eye A1 and the second eye A2 reach the equilibrium state, the processing module 110 controls the first indicator light D1 to emit light, prompts the measured person to start measuring, does not shake, and keeps stable, thereby ensuring the accuracy of the measurement. The second indicator light D2 is, for example, a yellow indicator light, and when the pressurizing module 140 applies pressure to the first eye A1, the processing module 110 controls the second indicator light D2 to emit light, so as to prompt the measured person to perform measurement. 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 value, which indicates that the force of the tested person pushing the first pressing portion 1021 and the second pressing portion 1022 is greater, the processing module 110 controls the third indicator light D3 to emit light, so that the tested person correctly places the intraocular pressure detection device in the eye socket again, and the intraocular pressure is measured again until the reference pressure is suitable and the first indicator light D1 is lighted, so that the intraocular pressure measurement is facilitated.
