In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1-4 show an intraocular pressure tracking measuring instrument according to the present invention for tracking and measuring pressure values inside an eyeball. Referring to the outline schematic diagram of the intraocular pressure tracking measuring instrument shown in fig. 1, the intraocular pressure tracking measuring instrument includes an eyecup body 1 and one or two probe assemblies 2 fixedly arranged on the eyecup body 1 and respectively corresponding to the eyes of the examinee. In the embodiment, the number of the probe assemblies 2 is two, so that the intraocular pressure of both eyes can be synchronously tracked and measured. In other embodiments, the number of probe assemblies 2 is one, and the intraocular pressure of only a single eye is tracked. It should be noted that: except for the part connected with the probe assembly 2, the other parts of the eyeshade body 1 are made of flexible materials, such as rubber, textile fabrics and the like, so that the eyeshade can be extruded and deformed. The eyeshade body 1 is connected with a belt 10 for fixing, and the eyeshade body 1 and the probe assembly 2 thereon can be fixed on the head of a user, so that the probe assembly 2 can be over against the eyes of the user.
Figure 2 shows a cross-sectional view of the intraocular pressure tracking measurement device along the centerline of the probe assembly. An inflatable air bag 3 is arranged in the eye patch body 1, and the air bag 3 deforms after being inflated, so that the eye patch body 1 deforms and expands outwards, and the air bag 3 is allowed to push the probe assembly 2 to move backwards to apply pressure to the eyeball behind. The directional words "front" and "rear" referred to in the present invention are defined with reference to the user's eye after the intraocular pressure tracking measurement instrument is worn on the user's head, and the side farther from the user's eye is the front, otherwise the side is the rear.
Fig. 3 shows probe assemblies 2, each of which probe assemblies 2 respectively comprises an ultrasonic sensor 21 for detecting whether the top of the eyeball is flattened and a pressure sensor 22 connected with the ultrasonic sensor 21. Each probe assembly 2 further comprises a connecting part 23, the connecting part 23 is fixedly connected with the eyeshade body 1, and the connecting part 23, the pressure sensor 22 and the ultrasonic sensor 21 are sequentially and fixedly connected from front to back. Wherein, the ultrasonic sensor 21 and the pressure sensor 22 are rigidly connected, so that the pressure value inside the eyeball can be obtained by reading the value of the pressure sensor 22.
Referring to fig. 2, the eyecup body 1 has a contact surface 11 matching the contour of the eye, the contact surface 11 can be pressed by the airbag 3 to be elastically deformed, the connecting portion 23 of the probe assembly 2 is fixedly connected to the contact surface 11, and the pressure sensor 22 and the ultrasonic sensor 21 are extended to the rear side of the contact surface 11, i.e., exposed outside the eyecup body 1. The probe assembly 2 is disposed behind the balloon 3 and preferably in contact with the balloon 3. In the measurement, the ultrasonic sensor 21 is in contact with the eyelid, and applies pressure to the eyeball through the eyelid. The ultrasonic sensor 21 includes an ultrasonic wave transmitter and receiver, transmits ultrasonic waves to the eyeball and receives the returned ultrasonic waves, and then judges whether or not the top of the eyeball (specifically, the front side of the eyeball, opposite to the fundus retina) is flattened by the returned ultrasonic waves.
Fig. 4 shows a block diagram of the intraocular pressure tracking measuring instrument. Referring to fig. 4, the intraocular pressure tracking measuring instrument further includes a controller 4, and the controller 4 may be provided in the eyecup body 1. The ultrasonic sensor 21 is electrically connected with the controller 4 so as to send a measurement feedback signal to the controller 4 after detecting that the top of the eyeball is flattened; the controller 4 is electrically connected to the pressure sensor 22 to read the pressure value of the pressure sensor 22 after receiving the measurement feedback signal.
The air bag 3 is communicated with an air inlet valve 30, and the controller 4 is connected with the air inlet valve 30 to control the air inlet valve 30 to be opened to inflate the air bag 3 at regular time or after receiving an inflation instruction of a user. The controller 4 is further configured to send a detection control signal to the ultrasonic sensor 21 after the air intake valve 30 is opened, and the ultrasonic sensor 21 sends an ultrasonic wave after receiving the detection control signal. The controller 4 is further configured to control the air intake valve 30 to close after receiving the measurement feedback signal, and stop inflating the airbag 3. That is, when the air bag 3 starts to inflate, the probe assembly 2 starts to generate pressure on the eyeball, and the ultrasonic sensor 21 sends out ultrasonic waves to monitor the current shape of the eyeball in real time; when the top of the eyeball is flattened, the air bag 3 stops inflating and starts deflating, and the probe assembly 2 stops moving backwards and gradually retracts forwards.
The intraocular pressure tracking measuring instrument further comprises a smart phone 5 or a tablet computer which is in communication with the controller 4 (such as communication through Bluetooth, wifi and the like), wherein the smart phone 5 or the tablet computer is used for receiving an inflation instruction input by a user and sending the inflation instruction to the controller 4. The controller 4 is further configured to send the eyeball internal pressure value to the smart phone 5 or the tablet computer.

The controller 4 comprises an MCU control chip and a communication device, such as a Bluetooth device and a wifi device. The screen of the smart phone 5 or the tablet computer can realize measurement data and can store or forward the measurement data.
The work flow of the intraocular pressure tracking measuring instrument is as follows: a user inputs an inflation instruction through the smart phone 5 or the tablet personal computer, and after the controller 4 receives the inflation instruction, the air inlet valve 30 is opened, or the air inlet valve 30 is opened at regular time in each measurement period; the air bag 3 is inflated; the ultrasonic sensor 21 sends ultrasonic waves to monitor the state of the eyeball; when monitoring that the top of the eyeball is pressed, the ultrasonic sensor 21 sends a measurement feedback signal to the controller 4; reading the value of the pressure sensor 22, and stopping the inflation and deflation of the air bag 3 to make the probe assembly 2 stop moving backwards and retreat forwards; the controller 4 obtains the pressure value inside the eyeball according to the read vertical direction of the pressure sensor 22, and then sends the pressure value inside the eyeball to the server 6, the smart phone 5, the tablet computer and the like for storage, display and the like.
The intraocular pressure tracking measuring instrument is integrally of an eye mask type, the air bag 3 is inflated to push the probe assembly 2 to move to generate pressure on eyeballs, the air bag 3 is deflated after the measurement is completed, the probe assembly 2 retracts, and the pressure is generated on the eyeballs only during the measurement. Whether the top of the eyeball is flattened or not is judged through the ultrasonic sensor 21, and the numerical value of the pressure sensor 22 is read only after the top of the eyeball is flattened, so that the pressure value inside the eyeball is obtained, and the use is convenient. The device can measure once at intervals, and achieves the purpose of tracking the intraocular pressure.
