Description

Technical Field

[0001] The present invention relates to the technical field of intraocular pressure measurement, and in particular to a contact-type intraocular pressure measurement method, device, equipment and storage medium based on force balance. Background Art

[0002] Intraocular pressure (IOP) is the pressure exerted by the contents of the eye on the wall of the eyeball and is an important reference for diagnosing eye diseases such as glaucoma. Currently, there are three main types of tonometers commonly used in clinical practice: applanation, indentation, and non-contact. Applanation tonometers, such as the Goldmann tonometer, are based on the Imbert-Fick law and measure IOP by flattening the cornea to a certain area and reading the external pressure value. They are considered to be the most accurate type of tonometer. However, this method requires local anesthesia for the patient and there is a risk of cross-infection between patients. Non-contact tonometers, such as the jet tonometer, deform the cornea by spraying air onto the surface, and calculate the IOP based on the airflow pressure, thus achieving non-contact measurement. However, there are large errors in the estimation of airflow velocity and applanation area, and the measurement accuracy is not high.

[0003] Existing methods for measuring intraocular pressure all have drawbacks. Professional intraocular pressure equipment is expensive and requires specialized training, resulting in a high learning curve. Portable intraocular pressure monitors are inaccurate and require a high learning curve. Most intraocular pressure monitors require the eye to be open for measurement, which carries a risk of contact infection. Some also require anesthesia, and disposable supplies can add additional costs. Therefore, there is an urgent need for an intraocular pressure measurement method that does not require the eye to be open, anesthesia, or disposable supplies, and offers high accuracy and ease of use.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not constitute an admission that the above content is prior art. Summary of the Invention

[0041] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] Reference Figure 1 , Figure 1 This is a schematic structural diagram of a contact-type intraocular pressure measurement device based on force balance in the hardware operating environment involved in an embodiment of the present invention.

[0043] like Figure 1As shown, the contact-type intraocular pressure measurement device based on force balance may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0044] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the contact-type intraocular pressure measurement device based on force balance, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0045] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and an eyelid contact pressure measurement program.

[0046] exist Figure 1 In the contact tonometer measurement device based on force balance shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the contact tonometer measurement device based on force balance of the present invention can be set in the contact tonometer measurement device based on force balance. The contact tonometer measurement device based on force balance calls the eyelid contact tonometer measurement program stored in the memory 1005 through the processor 1001, and executes the contact tonometer measurement method based on force balance provided in an embodiment of the present invention.

[0047] The embodiment of the present invention provides a contact type intraocular pressure measurement method based on force balance, referring to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a contact-type intraocular pressure measurement method based on force balance according to the present invention.

[0048] In this embodiment, the contact-type intraocular pressure measurement method based on force balance includes the following steps:

[0049] Step S10: placing the intraocular pressure measuring probe against the user's eyelid to measure and obtain a set of user intraocular pressure data;

[0050] It should be noted that, in a specific implementation, the intraocular pressure measurement probe includes a pressure sensor. Therefore, when the intraocular pressure measurement probe is placed against the user's eyelid for measurement, the pressure applied to the probe can be accurately obtained, that is, the user's intraocular pressure data set includes the pressure data applied to the probe.

[0051] Step S20: Acquire auxiliary measurement data;

[0052] It should be noted that, in the specific implementation, the auxiliary measurement data are essentially auxiliary parameters used for subsequent intraocular pressure calculation, which may include the user's eye structure parameters (eyelid thickness, corneal thickness and eyeball radius, etc.) and intraocular pressure-related mechanical parameters (Young's modulus and Poisson's ratio of the eyelid and cornea).

[0053] Step S30: performing calculation based on the user intraocular pressure data set and the auxiliary measurement data to obtain the user intraocular pressure value.

[0054] It can be understood that in a specific implementation, a corresponding physical model of the eyeball can be constructed based on the user's intraocular pressure data set and auxiliary measurement data, and then the user's intraocular pressure data set and auxiliary measurement data are input into the relevant formula of the physical model of the eyeball to calculate the intraocular pressure and obtain the user's intraocular pressure value.

[0055] This embodiment measures intraocular pressure by placing an intraocular pressure measurement probe against the user's eyelids to obtain a user intraocular pressure data set; obtains auxiliary measurement data; and calculates the user's intraocular pressure value based on the user's intraocular pressure data set and the auxiliary measurement data. This embodiment first uses the probe to flatten the cornea through the eyelids to obtain the user's intraocular pressure value, and then performs an intraocular pressure calculation to obtain the user's intraocular pressure value. The entire intraocular pressure measurement process does not require the patient to open their eyes, reducing patients' fear of intraocular pressure measurement and discomfort during the intraocular pressure measurement process, avoiding the risk of contact infection, and reducing the cost of intraocular pressure measurement.

[0056] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a contact-type intraocular pressure measurement method based on force balance according to the present invention.

[0057] Based on the above first embodiment, in this embodiment, step S10 specifically includes:

[0058] Step S11: placing the intraocular pressure measurement probe against the user's eyelid and applying external force so that the intraocular pressure measurement probe flattens the user's cornea through the eyelid to obtain the user's intraocular pressure data;

[0059] It should be noted that, in the specific implementation, in the process of measuring the user's intraocular pressure, in order to reduce data errors, the user's intraocular pressure data will be obtained repeatedly. Each process of obtaining the user's intraocular pressure data starts when the intraocular pressure measurement probe is placed against the user's eyelid and ends when the intraocular pressure measurement probe flattens the user's cornea. During this process, the pressure changes of the intraocular pressure measurement probe and the corresponding advancement distance of the measurement probe will be recorded and then integrated into the user's intraocular pressure data set.

[0060] Step S12: repeatedly acquiring user intraocular pressure data based on a preset data sample rule, and integrating all user intraocular pressure data to obtain a user intraocular pressure data set.

[0061] It can be understood that in the specific implementation, the preset data sample rule is essentially a restriction on the number of times the user's intraocular pressure data is repeatedly obtained under the premise of ensuring the data error requirement. For example, if at least five sets of data are required to meet the requirements of subsequent accurate intraocular pressure calculation under the premise of ensuring the data error requirement, the preset data sample rule can be set to five times, that is, the user's intraocular pressure data needs to be repeatedly obtained five times.

[0062] In this embodiment, the intraocular pressure measurement probe is first placed against the user's eyelid and external force is applied, so that the intraocular pressure measurement probe flattens the user's cornea through the eyelid to obtain the user's intraocular pressure data, and then the user's intraocular pressure data is repeatedly obtained based on the preset data sample rules, and all the user's intraocular pressure data are integrated to obtain a user intraocular pressure data set, which provides a basis for subsequent calculation of the intraocular pressure value.

[0063] Furthermore, obtaining auxiliary measurement data specifically includes: inputting user personal data based on the intraocular pressure measurement instruction; integrating the user personal data with pre-stored intraocular pressure auxiliary parameters to obtain auxiliary measurement data.

[0064] It should be noted that, in a specific implementation, the user's personal data is essentially personal body data that needs to be measured by specific instruments, which may include eyelid thickness, corneal thickness, eyeball radius, etc.

[0065] It should also be noted that, in a specific implementation, the pre-stored intraocular pressure auxiliary parameters are essentially mechanical parameters in the intraocular pressure measurement calculation process, which may include the Young's modulus and Poisson's ratio of the eyelid and cornea.

[0066] It is understandable that in actual implementation, the pre-stored auxiliary intraocular pressure parameters (mechanical parameters) are universal and difficult to obtain. Therefore, they are usually determined by group data obtained through experimental research and statistical fitting. In addition, due to the large difference between the intraocular pressure values of normal people and patients, in order to reduce errors, the group data needs to be classified in order to obtain a more accurate eye model. The group data can be specifically classified according to factors such as whether the patient is ill, age, and race (white, black, and yellow).

[0067] refer to Figure 4 , Figure 4 This is a flow chart of a third embodiment of a contact-type intraocular pressure measurement method based on force balance according to the present invention.

[0068] Based on the above first embodiment, in this embodiment, step S30 specifically includes:

[0069] Step S31: Processing the user intraocular pressure data set to obtain standard user intraocular pressure data;

[0070] It can be understood that in the specific implementation, the standard user intraocular pressure data is obtained based on data processing (curve fitting processing, algorithm filtering processing or standardization and normalization processing, etc.) of the intraocular pressure data of each user in the user intraocular pressure data set, which is more in line with the user's actual intraocular pressure data, thereby improving the accuracy of subsequent intraocular pressure calculations.

[0071] Step S32: performing a first-stage intraocular pressure calculation based on the standard user intraocular pressure data and the auxiliary measurement data to obtain a first intraocular pressure calculation result;

[0072] It should be noted that, in the specific implementation, the essential purpose of the first stage of intraocular pressure calculation is to obtain the eyelid deformation z ∈,l , move z l Distance and corneal movement distance z e , and then due to the flattening of the cornea, the distance z0 is z ∈,l 、z l and z e The sum of (i.e. z0 = z l +z ∈,l +z e ), so the probe flattens the cornea advancing distance z0 (i.e., the first intraocular pressure calculation result) can be obtained in the end.

[0073] Step S33: Perform a second-stage intraocular pressure calculation based on the first intraocular pressure calculation result and the auxiliary measurement data to obtain the user's intraocular pressure value.

[0074] It should be noted that, in the specific implementation, the actual purpose of the second stage intraocular pressure calculation is to obtain the user's intraocular pressure value (IOP). The calculation process is to substitute the first intraocular pressure calculation result and auxiliary measurement data into the eyeball model formula to finally obtain the user's intraocular pressure value.

[0075] This embodiment first processes the user's intraocular pressure data set, then performs a first-stage intraocular pressure calculation based on the obtained standard user intraocular pressure data and auxiliary measurement data, and finally performs a second-stage intraocular pressure calculation based on the first intraocular pressure calculation result and the auxiliary measurement data to obtain the user's intraocular pressure value, thereby achieving accurate measurement of the user's intraocular pressure.

[0076] Furthermore, a first-stage intraocular pressure calculation is performed based on the standard user intraocular pressure data and the auxiliary measurement data to obtain a first intraocular pressure calculation result. The first-stage intraocular pressure calculation formula is:

[0077]

[0078] Among them, z ∈,l For eyelid deformation, z l is the probe moving distance, z e is the distance the cornea moves, z0 is the distance the cornea is flattened, g is the radius of the probe, F is the external force applied by the probe, h l is the thickness of the eyelid, E l is the Young's modulus of the eyelid, a e is the radius of the middle layer of the cornea, a l is the radius of the middle layer of the eyelid.

[0079] Furthermore, a second-stage intraocular pressure calculation is performed based on the first intraocular pressure calculation result and the auxiliary measurement data to obtain the user's intraocular pressure value. The second-stage intraocular pressure calculation formula is:

[0080]

[0081] Where P(z0) is the value at z0 of the curve of probe pressure versus advancement distance, g is the probe radius, IOP is the intraocular pressure, P is the probe pressure, and h is the probe pressure. e Corneal thickness, h l is the thickness of the eyelid, E e is the Young's modulus of the cornea, E l is the Young's modulus of the eyelid, a e is the radius of the middle layer of the cornea, a l is the radius of the middle layer of the eyelid, v e is the corneal Poisson's ratio, ν l is the eyelid Poisson's ratio.

[0082] It can be understood that in the specific implementation, there is a positive correlation between the probe detection pressure and the probe advancement distance. Therefore, the curve of the probe detection pressure changing with the advancement distance can be fitted through multiple measurement records, where P(z0) is the value at z0 of the curve of the probe detection pressure changing with the advancement distance.

[0083] Furthermore, the calculation is performed based on the user intraocular pressure data set and the auxiliary measurement data to obtain the user intraocular pressure value, which also includes: performing data detection on each data of the user intraocular pressure data set and the auxiliary measurement data according to the data quality detection algorithm to obtain corresponding data detection results, and the data detection results are used to judge the accuracy of the user intraocular pressure value.

[0084] It is understandable that, in a specific implementation, the data quality detection algorithm can provide a reasonable value range based on the data category, thereby helping to determine the rationality and accuracy of the calculated user intraocular pressure value.

[0085] In addition, an embodiment of the present invention also proposes a computer-readable storage medium storing a computer program, wherein the storage medium stores an eyelid contact pressure measurement program, and when the eyelid contact pressure measurement program is executed by a processor, the steps of the contact pressure measurement method based on force balance as described above are implemented.

[0086] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described one by one here.

[0091] The intraocular pressure calculation module 30 performs calculations based on the user's intraocular pressure data set and the auxiliary measurement data to obtain the user's intraocular pressure value.

[0092] This embodiment measures intraocular pressure by placing an intraocular pressure measurement probe against the user's eyelids to obtain a user intraocular pressure data set; obtains auxiliary measurement data; and calculates the user's intraocular pressure value based on the user's intraocular pressure data set and the auxiliary measurement data. This embodiment first uses the probe to flatten the cornea through the eyelids to obtain the user's intraocular pressure value, and then performs an intraocular pressure calculation to obtain the user's intraocular pressure value.
