[0049] With reference to FIGS. 1-11, the embodiment provides an intraocular pressure measuring device, which comprises a measuring body 1 for measuring intraocular pressure and a bearing body 2 for bearing and supporting the measuring body 1, facilitating stable use of the measuring body 1 to ensure stability and convenient use of the measuring body 1. The bearing body 2 is also used for alignment of the eye and the measuring end of the measuring body 1, so that the measuring end of the measuring body 1 can accurately contact the eye, thereby accurately obtaining the intraocular pressure of the eyeball part and ensuring measurement accuracy.

[0050] Further, as shown in FIGS. 2-5, the measuring body 1 comprises a pressure measuring module 11, an eye contact piece 12, and a pushing mechanism 13. The pushing mechanism 13 is used to push the eye contact piece 12 to contact the eye, generate pressure information and contact signals. The pressure measuring module 11 is used to detect and obtain the pressure information and contact signals generated when the eye contact piece 12 contacts the eye. The pressure measuring module 11 can be a pressure sensor, and the eye contact piece 12 can be a contact probe.

[0051] The eye contact piece 12 is pushed by the pushing mechanism 13 to contact the eye, to generate pressure information and contact signals. The pressure measuring module 11 quickly detects and obtains the pressure information and contact signals generated when the eye contact piece 12 contacts the eye, thereby directly measuring the intraocular pressure. This intraocular pressure measuring method measures the intraocular pressure through the eyelid with the eyes closed, without direct contact with the eyeball, avoiding the risk of eyeball infection, ensuring the safety of the eyeball, and also allowing the user to not feel psychological pressure and fear. At the same time, the operation is simple and efficient, and the intraocular pressure can be directly measured in a short time after starting.

[0052] Further, as shown in FIG. 4, the pushing mechanism 13 is connected to the pressure measuring module 11, and the eye contact piece 12 is connected to the detection end of the pressure measuring module 11. During the intraocular pressure measurement process, the pushing mechanism 13 pushes the pressure measuring module 11, which in turn drives the eye contact piece 12 to move.

[0053] Further, as shown in FIG. 2, the measuring body 1 further comprises an alignment mechanism 19 for pupil alignment, so that the axis of the eye contact piece 12 is on the same straight line as the pupil of the eye.

The moving connecting block 1323 is connected with the pressure measuring module 11.

[0056] The driving member 131 can be a stepper motor. During the intraocular pressure measurement, the driving member 131 drives the screw rod 1321 to rotate forward, the screw rod 1321 rotates to drive the moving connecting block 1323 to move in the axial direction of the eye contact member 12, thereby driving the pressure measuring module 11 to move in the axial direction together with the eye contact member 12, and then the eye contact member 12 contacts the eye to measure the intraocular pressure. After the intraocular pressure is measured, the driving member 131 drives the screw rod 1321 to rotate reversely, so as to drive the moving connecting block 1323 to move reversely, i.e. to move away from the pupil, so that the eye contact member 12 retreats into the shell 15, and the intraocular pressure measurement is completed.

[0057] Further, as shown in FIGS. 10-11, the bearing body 2 comprises a bearing frame 21, and the bearing frame 21 is provided with a receiving cavity 211, and the measurement body 1 is installed in the receiving cavity 211.

[0067] The activity adjusting piece 14 is arranged so that the measuring body 1 is convenient to dismount and install on the bearing body 2. When the measuring body needs to be dismounted, two activity keys 14 can be pressed at the same time, so that the inclined surface of the activity key 14 slides with the two side inclined surfaces of the adjusting part 1421, and then the adjusting part 1421 drives the activity column 142 to extend and retract in the vertical direction and retract into the shell 15, so as to release the limiting connection between the activity column 142 and the bearing body 2. When installing, the two activity keys 14 are released and not pressed. Under the action of the pulling force of the spring 143, the adjusting part 1421 is pulled to shorten the distance between the shell 15, so that the activity column 142 extends out of the shell 15 and is limitedly connected with the bearing body 2. The second limiting groove 213 can be arranged on the bearing body 2 to facilitate the limiting clamping of the activity column 142.
