[0066] See also Figure 1 and Figure 2 , Figure 1 A flow chart of an intraocular pressure detection method provided by an embodiment of the present invention; Figure 2 The first schematic diagram of an intraocular pressure detection device provided by an embodiment of the present invention. An intraocular pressure detection method provided by an embodiment of the present invention includes:

[0067] S10 obtains a target pressure value and a target displacement value during the process of applying pressure to the eyeball of the target object.

[0068] Specifically, pressure is applied to the target object, and then the pressure value and displacement value of the target object's eyeball during the pressure application process are recorded, wherein the pressure value and displacement value of the target object's eyeball during the pressure application process are variable, and therefore, multiple sets of target pressure values ​​and target displacement values ​​can be obtained during the application process.

[0069] In this embodiment, the target pressure value of the target object during the eye pressure application process can be measured by the pressure sensor 210 , and the target displacement value of the target object during the eye pressure application process can be measured by the displacement sensor 220 .

[0070] S20 constructs a target relationship according to the target pressure value and the target displacement value; wherein the target relationship is a corresponding relationship between the target pressure value and the target displacement value.

[0071] Specifically, during the pressure application process, a corresponding relationship is established between the target pressure value and the target displacement value recorded at the same time, so as to establish a target relationship between the target pressure value and the target displacement value at the same time. The relationship between the target pressure value and the target displacement value can characterize the intraocular pressure state of the eyeball of the target object.

[0072] S30 acquires several reference relationships.

[0073] S40 compares the target relationship with a plurality of reference relationships to determine the intraocular pressure state of the target object.

[0074] Specifically, several reference relationships are used as reference objects, and the target relationship is compared with the several reference relationships to obtain a reference relationship closest to the target relationship, so as to determine the intraocular pressure state of the target object according to the reference object corresponding to the reference relationship.

[0075] In the present application, by obtaining the target pressure value and the target displacement value in the process of applying pressure to the eyeball of the target object, the displacement value of the eyeball of the target object under any pressure state can be obtained, that is, the intraocular pressure data of the eyeball under dynamic conditions can be obtained, which reduces the possibility of affecting the accuracy of the data results due to poor compliance of the target object. Then, based on the target relationship between the target displacement value and the target pressure value obtained under dynamic conditions and compared with several reference relationships, the intraocular pressure state of the target object can be determined, thereby improving the accuracy of intraocular pressure detection.

[0076] It should be noted that the traditional finger measurement method is that the ophthalmologist touches and presses the eyeball with his hand to feel the hardness of the eyeball. However, this method is a qualitative method and has a certain degree of subjectivity, so there is a certain degree of distortion. In this application, by recording the target pressure value and target displacement value at the same time, and constructing a target relationship between the target pressure value and target displacement value at the same time, the pressure and displacement when pressing the eyeball are quantified, thereby improving the accuracy of intraocular pressure measurement.

[0077] Furthermore, during the pressure application process, the eyelids in the closed state are pressed, and the pressure value is the force applied to the eyelids, thereby reducing the problem of poor compliance of the target object and improving adaptability.

[0078] See also Figure 1 and Figure 2 In one embodiment, S30 specifically includes:

[0079] S31 obtains reference pressure values ​​and reference displacement values ​​during the process of applying pressure to different intraocular pressure phantoms.

[0080] Specifically, pressure is applied to different intraocular pressure phantoms, and then the pressure value and displacement value of each intraocular pressure phantom during the pressure application process are recorded, wherein the pressure value and displacement value of each intraocular pressure phantom during the pressure application process are variable, and therefore, during the application process, each intraocular pressure phantom can obtain multiple groups of reference pressure values ​​and reference displacement values. In this embodiment, the reference pressure value of each intraocular pressure phantom during the pressure application process can be measured by the pressure sensor 210, and the reference displacement value of each intraocular pressure phantom during the pressure application process can be measured by the displacement sensor 220.

[0081] S32 constructs a reference relationship according to the reference pressure value and the reference displacement value of each phantom, wherein the intraocular pressure value of each phantom is known.

[0082] Specifically, during the pressure application process, the reference pressure value and the reference displacement value recorded at the same time of each intraocular pressure phantom are established in a corresponding relationship, so as to construct a reference relationship between the reference pressure value and the reference displacement value at the same time. The intraocular pressure value of each phantom is known, so that the reference relationship corresponding to each phantom can correspond to the intraocular pressure value, so that the intraocular pressure state of the target object can be determined according to the target relationship and the reference relationship of each phantom. Among them, the number of phantoms can be one, two, or more.

[0083] Furthermore, the target relationship is a functional relationship between the target pressure value and the target displacement value of the eyeball of the target object at the same time during the pressure application process, and the reference relationship is a functional relationship between the reference pressure value and the reference displacement value of the reference object at the same time during the pressure application process. That is, the pressure and displacement are quantified, which is convenient for comparison and improves the accuracy of intraocular pressure measurement.

[0084] See also Figure 1 and Figure 2 In one embodiment, S40 specifically includes:

[0085] S41 determines the target value and reference value corresponding to the target relationship and the reference relationship of each model at the preset parameter value; wherein the target value and reference value corresponding to the preset parameter value include: the target pressure value and each reference pressure value corresponding to the preset displacement value; or the target displacement value and each reference displacement value corresponding to the preset pressure value; or the target slope value and each reference slope value corresponding to the preset displacement value; or the target slope value and each reference slope value corresponding to the preset pressure value.

[0086] Specifically, the setting of the preset parameter value can reduce the interference of the eyelids, meridians and blood vessels in the eyeball, etc., so that the corresponding target value and reference value are more meaningful for reference when the preset parameter value is set. Among them, when the preset parameter value is the preset displacement value, that is, the displacement value is the independent variable and the pressure value is the dependent variable, the higher the hardness, the larger the corresponding pressure value and slope value, when the preset parameter value is the preset pressure value, that is, the pressure value is the independent variable and the displacement value is the dependent variable, the higher the hardness, the smaller the corresponding displacement value and slope value, that is, when the preset parameter value is the preset pressure value, that is, the pressure value is the independent variable and the displacement value is the dependent variable, the higher the hardness, the smaller the corresponding displacement value and slope value, that is, when the preset parameter value is set, the corresponding target value and reference value can characterize the hardness.

[0087] In one embodiment, the corresponding target value and reference value when the parameter value is preset include: a target slope value and each reference slope value corresponding to the preset displacement value or a target slope value and each reference slope value corresponding to the preset pressure value.

[0088] Specifically, the target slope can map the relationship between the target pressure value and the target position value within the preset parameter value. The target slope is a parameter characterizing the intraocular pressure of the target object's eyeball. If the preset parameter value is the preset pressure value, that is, the target pressure value is the independent variable and the target displacement value is the dependent variable, then the smaller the target slope is, the greater the intraocular pressure of the target object's eyeball, and vice versa. If the preset parameter value is the preset displacement value, that is, the target displacement value is the independent variable and the target pressure value is the dependent variable, then the larger the target slope is, the greater the intraocular pressure of the target object's eyeball, and vice versa.

[0089] The reference slope can map the relationship between the reference pressure value and the reference position value within the preset displacement range. The reference slope is a parameter that characterizes the intraocular pressure of the phantom. If the preset parameter value is the preset pressure value, that is, the reference pressure value is the independent variable and the reference displacement value is the dependent variable, then the smaller the reference slope, the greater the intraocular pressure of the phantom, and vice versa. If the preset parameter value is the preset displacement value, that is, the reference displacement value is the independent variable and the reference pressure value is the dependent variable, then the larger the reference slope, the greater the intraocular pressure of the phantom, and vice versa.

[0090] It should be noted that the objective function relationship can construct an objective function curve with the target pressure value as the horizontal axis and the target displacement value as the vertical axis, that is, an objective function curve with the target pressure value as the independent variable and the target displacement value as the dependent variable, or an objective function curve with the target displacement value as the horizontal axis and the target pressure value as the vertical axis, that is, an objective function curve with the target displacement value as the independent variable and the target pressure value as the dependent variable. Since the objective function curve is not necessarily a straight line but may be a curve, it is necessary to fit it within the preset parameter value to obtain the target slope. The reference slope is obtained in the same way as the target slope, so it will not be repeated.

[0091] S42 obtains the intraocular pressure value of the target object according to the target value and each reference value.

[0092] Specifically, each reference value has a certain mapping relationship with the intraocular pressure value of the corresponding phantom, so that the intraocular pressure value of the target object can be obtained through the target value, the reference value of each phantom and the intraocular pressure value of each phantom.

[0093] In one embodiment, S42 specifically includes:

[0094] Obtain the difference between the target value and each reference value;

[0095] Determine the minimum difference;

[0096] According to the minimum difference, determining a reference relationship corresponding to the minimum difference and an intraocular pressure value of the corresponding intraocular pressure model;

[0097] The intraocular pressure value of the target object is determined according to the minimum difference, the determined reference relationship corresponding to the minimum difference, and the intraocular pressure value of the corresponding intraocular pressure model.

[0098] Specifically, when the minimum difference is less than or equal to the first preset difference, the intraocular pressure value of the eyeball of the target object is equal to the intraocular pressure value of the intraocular pressure phantom corresponding to the minimum difference, and when the minimum difference is greater than the first preset difference and is within a different preset difference range, the intraocular pressure value of the eyeball of the target object is the intraocular pressure value of the phantom corresponding to the minimum difference multiplied by the preset coefficient corresponding to the corresponding preset difference range. It should be noted that the first preset difference refers to a difference within the normal range.

[0099] See also Figure 1 and Figure 2 In one embodiment, S30 specifically includes:

[0100] A reference pressure value and a reference displacement value are obtained during the process of applying pressure to a reference body part of the target object to obtain a reference relationship; wherein the hardness value of the reference body part is within the range of the hardness value of a normal eyeball.

[0101] Specifically, a body part with a hardness value close to that of a normal eyeball is selected, and pressure is applied to the part, and the pressure value and displacement value of the reference body part during the pressure application process are recorded, wherein the pressure value and displacement value of the reference body part during the pressure application process are variable, and therefore, during the application process, multiple groups of reference pressure values ​​and reference displacement values ​​can be obtained for the reference body part, and a reference relationship is constructed according to the corresponding reference pressure values ​​and reference displacement values. In this embodiment, the reference pressure value of the reference body part during the pressure application process can be measured by the pressure sensor 210, and the reference displacement value of the reference body part during the pressure application process can be measured by the displacement sensor 220. Preferably, the reference body part is the tip of the nose.

[0102] See also Figure 1 and Figure 2In another embodiment, S30 specifically includes:

[0103] A reference pressure value and a reference displacement value are obtained during the process of applying pressure to two reference body parts of the target object, and two reference relationships are obtained respectively; wherein the hardness values ​​of the two reference body parts are different, and the hardness value of one reference body part is greater than the hardness value of a normal eyeball, and the hardness value of the other reference body part is less than the hardness value of a normal eyeball.

[0104] Specifically, a body part with a hardness value greater than the normal eyeball hardness value is selected, and a body part with a hardness value less than the normal eyeball hardness value is selected, and pressure is applied to these two reference body parts, and the pressure value and displacement value of each reference body part during the pressure application process are recorded, wherein the pressure value and displacement value of each reference body part during the pressure application process are variable, and therefore, during the application process, multiple groups of reference pressure values ​​and reference displacement values ​​can be obtained for the reference body parts, and the reference relationship of the components is determined according to the corresponding reference pressure values ​​and reference displacement values. In this embodiment, the reference pressure value of each reference body part during the pressure application process can be measured by the pressure sensor 210, and the reference displacement value of each reference body part during the pressure application process can be measured by the displacement sensor 220. Preferably, the reference body parts are the forehead and the lips.

[0105] See also Figure 1 and Figure 2 In yet another embodiment, S30 specifically includes:

[0106] Reference pressure values ​​and reference displacement values ​​are obtained during the process of applying pressure to three reference body parts of the target object, and three reference relationships are obtained respectively; wherein the hardness values ​​of the three reference body parts are all different, and the hardness value of one reference body part is within the range of the normal eyeball hardness value, the hardness value of one reference body part is greater than the normal eyeball hardness value, and the hardness value of one reference body part is less than the normal eyeball hardness value.

[0107] Specifically, a body part with a hardness value greater than the normal eyeball hardness value is selected, a body part with a hardness value less than the normal eyeball hardness value is selected, and a body part with a hardness value close to the normal eyeball hardness value is selected, and pressure is applied to these three reference body parts, and the pressure value and displacement value of each reference body part during the pressure application process are recorded, wherein the pressure value and displacement value of each reference body part during the pressure application process are variable, therefore, during the application process, multiple groups of reference pressure values ​​and reference displacement values ​​can be obtained for the reference body parts, and the reference relationship is constructed according to the corresponding reference pressure values ​​and reference displacement values. In this embodiment, the reference pressure value of each reference body part during the pressure application process can be measured by the pressure sensor 210, and the reference displacement value of each reference body part during the pressure application process can be measured by the displacement sensor 220. Preferably, each reference body part is the forehead, the lips and the nose.

[0108] It should be noted that the hardness value at the lips is lower than the hardness value of the eyeball under normal intraocular pressure, the hardness value at the nose tip is close to the hardness value of the eyeball under normal intraocular pressure, and the hardness value at the forehead is greater than the hardness value of the eyeball under normal intraocular pressure.

[0109] See also Figure 1 and Figure 2 In other embodiments, the number of reference body parts can be greater than three, as long as the hardness value of at least one reference body part is greater than the normal eyeball hardness value, the hardness value of at least one reference body part is less than the normal eyeball hardness value, and the hardness value of at least one reference body part is within the range of the normal eyeball hardness value.

[0110] See also Figure 1 and Figure 2 In one embodiment, when the hardness value of the reference body part is one and is within the range of normal eyeball hardness values, S40 specifically includes:

[0138] See also Figure 1 , Figure 2 And pictures, Figure 3 A second schematic diagram of an intraocular pressure detection device provided in an embodiment of the present invention. An embodiment of the present invention also provides an intraocular pressure detection device for executing the above-mentioned intraocular pressure detection method. The intraocular pressure detection device includes a detection device 100 and a processor. The detection device 100 includes a pressure sensor 210 and a displacement sensor 220. The pressure sensor 210 and the displacement sensor 220 are communicatively connected to the processor. The pressure sensor 210 is used to measure the target pressure value during the process of applying pressure to the eye of the target object, and the displacement sensor 220 is used to measure the target displacement value during the process of applying pressure to the eye of the target object. The processor is used to determine the intraocular pressure state of the target object based on the relationship between the target pressure value and the target displacement value, and a number of reference relationships.

[0139] Specifically, in the present application, by obtaining the target pressure value of the pressure sensor 210 and the target displacement value of the displacement sensor 220 during the process of applying pressure to the target object's eyeball, it is possible to obtain the displacement value of the target object's eyeball under any pressure state, that is, the intraocular pressure data of the eyeball under dynamic conditions can be obtained, thereby reducing the possibility of affecting the accuracy of the data results due to poor compliance of the target object. The processor then compares the target relationship between the target displacement value and the target pressure value obtained under dynamic conditions with several reference relationships to determine the intraocular pressure state of the target object, thereby improving the accuracy of intraocular pressure measurement.

[0140] See also Figure 2 and Figure 3 In one embodiment, the intraocular pressure detection method further includes calibration, wherein the intraocular pressure detection device can be compared with reference values ​​of each phantom to determine whether the measurement is accurate. The intraocular pressure detection device can also be compared with reference values ​​of each reference body part to determine whether the measurement is accurate.

[0141] See also Figure 2 and Figure 3 In one embodiment, the detection device 100 also includes an image detector, which is communicatively connected to the processor. The image detector is used to obtain image information of the measured part and transmit the image information to the processor. The processor is used to establish a matching relationship between the image information and a reference pressure value and a reference displacement value obtained at the measured part.

[0142] Specifically, the processor is used to determine the measured part according to the image information, and then establish a matching relationship between the measured part and the reference pressure value and the reference displacement value measured there, that is, they can correspond. When measuring the reference pressure value and the reference displacement value during the pressure application process of at least three reference body parts, each reference body part corresponds to the corresponding pressure value and displacement value, so that by comparing the target relationship with several reference relationships, the body part with a hardness close to the eyeball of the target object can be quickly determined, thereby determining the intraocular pressure state of the target object.

[0143] When measuring the body part of the target object multiple times, the processor can obtain the average of the target pressure value and the target displacement value at the same time based on multiple sets of target pressure values ​​and target displacement values, thereby improving the accuracy of the obtained target relationship and improving the accuracy of intraocular pressure measurement.

[0144] In other embodiments, the pressure application process of each reference body part can be performed in a set order, so as to determine the reference body part by judging the arrangement order of the reference relationship closest to the target relationship to determine the intraocular pressure state of the eyeball. The number of measurements of each reference body part can also be set in advance according to the setting.

[0145] See also Figure 2 and Figure 3 In one embodiment, the detection device 100 further includes a wearable item 300, the pressure sensor 210 and the displacement sensor 220 are disposed on the wearable item 300, and the wearable item 300 is used to be worn by the target object.

[0146] Specifically, the wearable component 300 is provided with a mounting hole 110 for inserting a finger. When the finger presses a body part through the detection device 100, the target object can control the force at will, thereby reducing the problem of poor compliance of the target object and improving the convenience of measurement.

[0147] In this embodiment, by putting the wearable device 300 on the finger, the tactile function of the finger skin can be simulated, and the purpose is to combine the traditional finger pressure method to measure the intraocular pressure, and the pressure sensor 210 and the displacement sensor 220 are used to digitize the process of finger pressure measurement, thereby improving the convenience of intraocular pressure measurement, reducing costs, and improving the adaptability of intraocular pressure detection equipment. In other embodiments, the wearable device 300 can also be a strap, etc.

[0148] See also Figure 2 and Figure 3 In one embodiment, the intraocular pressure detection device also includes a display, which is communicatively connected to the processor, and the display is installed on the wearable device 300.

[0149] Specifically, the display is used to display the intraocular pressure measurement results, and the display interface may be integrated with control buttons, such as start calibration, end calibration, start measurement, end measurement, etc., or first measurement, second side measurement, etc. In other embodiments, it can also be remotely transmitted to the mobile terminal software, and the mobile terminal software may also integrate the above control buttons. Preferably, the wearable component 300 is formed by curling the flexible substrate.

[0150] Furthermore, the wearable component 300 includes a first part 310 and a second part 320 which are separately arranged. The first part 310 and the second part 320 are both provided with mounting holes 110 and are both used to be worn by fingers. The pressure sensor 210 and the displacement sensor 220 are arranged in the first part 310, and the display and the processor are arranged in the second part 320. The first part 310 and the second part 320 are separately arranged, which is convenient for wearing, while reducing the interference of the force applied by the bending of the fingers, and the interference of the display and the processor when the fingers are bent, thereby improving the reliability of the intraocular pressure detection device. In other embodiments, the first part 310 and the second part 320 are integrally formed.

[0151] Furthermore, the processor is electrically connected to the pressure sensor 210 and the displacement sensor 220 through the flexible wire 400, thereby avoiding confusion between the corresponding first part 310 and the first part 320 and other components.

[0152] See also Figure 2 and Figure 3 In another embodiment, the second part 320 is worn on the wrist, thereby reducing interference with the display and the processor when the fingers are bent, thereby improving the reliability of the intraocular pressure detection device.

[0153] In one embodiment, the detection device 100 further includes a sound announcer, which is electrically connected to the processor and is used to verbally prompt the measured position or intraocular pressure result.

[0154] In one embodiment, the processor is disposed outside the wearable device 300, and data transmission between the displacement sensor 220 and the pressure sensor 210 and the processor can be achieved through communication connection.
