Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intraocular pressure measuring equipment, and particularly relates to an intraocular pressure mold bottom acquisition system and method. BACKGROUND

[0002] Intraocular pressure, the pressure inside the eyeball, is an important factor in maintaining the shape and function of the eyeball. The normal range of intraocular pressure is between 10 and 21 millimeters of mercury (mmHg). The maintenance of intraocular pressure depends on the dynamic balance of aqueous humor, which is produced by the ciliary body inside the eye, then flows through the anterior chamber, and is discharged to the outside of the eye through the angle between the iris and the cornea. If the production of aqueous humor is excessive or the discharge is blocked, the intraocular pressure will rise.

[0003] In the prior art, when the intraocular pressure is detected, it is difficult to directly measure the intraocular pressure in the living eyeball due to the complex internal structure of the eyeball. When the intraocular pressure of the eyeball is measured, the staff needs to insert the pressure charging mechanism into the eyeball, and input the liquid into the eyeball through the pressure charging mechanism. However, when the liquid is input into the eyeball, the liquid in the eyeball may overflow from the connection between the pressure charging mechanism and the eyeball due to poor sealing, which increases the influence of external factors on the experimental results and reduces the accuracy and reliability of the experimental data.

[0004] Therefore, it is necessary to provide an intraocular pressure mold bottom acquisition system and method to solve the above problems. SUMMARY

The eyeball supporting mechanism is used for fixing the eyeball. The hydraulic module is used for charging hydraulic pressure into the eyeball and monitoring the pressure change in the eyeball.

[0037] Referring to Figures 1-2 , one end of the hydraulic pipe 32 is connected with the hydraulic container 31, the other end of the hydraulic pipe 32 is connected with the eyeball, the first pressure sensor 34 and the hydraulic switch 35 are arranged on the connecting pipe 461, the second pressure sensor 36 is arranged in the eyeball, the manual valve 37 is arranged on the hydraulic pipe 32, the first pressure sensor 34, the second pressure sensor 36 and the hydraulic switch 35 are electrically connected with the hydraulic controller 33, and the hydraulic controller 33 is electrically connected with the computer 1; the air pressure switch 24 is arranged on one end of the air pressure pipe 25, the other end of the air pressure pipe 25 is connected with the air pressure container 21, the manual valve 22 is arranged on the air pressure pipe 25, the third pressure sensor 23 is arranged on the air pressure pipe 25, the third pressure sensor 23 and the air pressure switch 24 are electrically connected with the air pressure controller 26, and the air pressure controller 26 is electrically connected with the computer 1.

[0038] When the intraocular pressure mold base is obtained, the eyeball is fixed through the eyeball supporting mechanism, the sterile liquid tank in the hydraulic container 31 is filled into the eyeball by opening the manual valve 37 and the hydraulic switch 35, the first pressure sensor 34 monitors the liquid pressure in the hydraulic pipe 32, the second pressure sensor 36 monitors the pressure in the eyeball, when the pressure value monitored by the second pressure sensor 36 is stable, the hydraulic switch 35 and the manual valve 37 are closed, then the air pressure switch 24 and the manual valve 22 are opened, so that the air pressure pipe 25 is communicated with the air pressure container 21, at this time, the end of the air pressure pipe 25 far away from the air pressure container 21 blows the eyeball after punching, the third pressure sensor 23 monitors the blowing pressure and transmits the monitored blowing pressure information to the computer 1.

[0039] At the same time of blowing air by the air pressure tube 25, the infrared image sensor 11 is opened, the infrared image sensor 11 emits light, the light is projected onto the eyeball through the half-mirror 12, the light is reflected by the eyeball and forms an image through the shift lens 13, the image sensor 14 acquires the image formed by the shift lens 13, and the image is transmitted to the computer 1.

[0040] During the imaging process, due to the force of the air pressure on the eyeball, the eyeball will deform. First, the air pressure pulse of the air pressure tube 25 is projected onto the surface of the eyeball, causing the cornea in the eyeball to deform from a natural curvature state to a concave state. In this process, the cornea will experience a first flattening state. Second, the cornea reaches a maximum indentation state, at which time the cornea will have a short oscillation period. Then, the cornea will recover from the maximum indentation state to its natural state. In this process, the cornea will experience a second flattening state. At the same time of the air pressure tube 25 emitting the air pressure pulse, the image sensor 14 captures multiple corneal deformation photos and transmits the photo information to the computer 1. In the computer 1, the blowing pressure, the eyeball pressure and the eyeball deformation model are obtained by calculation; for example: (after the hydraulic module fills the eyeball with sterile liquid, the pressure information Px of the eyeball is recorded, the air pressure module blows the surface of the eyeball for 30 milliseconds, the eyeball deforms, the hydraulic module monitors the pressure change of the eyeball and records 150 pressure changes of the eyeball in 30 milliseconds, and the high-speed imaging module acquires 150 photos of the eyeball deformation, so that a group of data relationship between the eyeball pressure and the deformation amount within a certain time can be obtained).

[0041] In this way, by capturing a large number of deformation photos of the eyeball in a very short time, the accuracy of the data is improved. Through the cooperation of the hydraulic module and the air pressure module, the pressure inside the eyeball changes in three periods, and the eyeball deforms in three periods, so that the high-speed imaging module can capture high-definition photos of the eyeball deformation, and the accuracy of the intraocular pressure data acquisition is realized.

[0044] When the eyeball is fixed, the servo motor 451 drives the drive rod 452 to rotate, so that the two connecting rods 453 drive the two slide columns 42 to slide in opposite directions on the support 41, so that the first clamping plate 43 and the second clamping plate 44 are separated from each other, then the eyeball is placed between the two clamping plates, and the servo motor 451 is reversely rotated, so that the first clamping plate 43 and the second clamping plate 44 clamp the eyeball, then the sliding handle 468 is slid, the sliding handle 468 drives the diaphragm fixing ring 464 through the pull rod 467, so that the diaphragm fixing ring 464 and the soft diaphragm 463 move to between the connecting pipe 461 and the fixed pipe 462, then one end of the connecting pipe 461 provided with the soft diaphragm 463 is inserted into the eyeball, after the connecting pipe 461 is inserted into the eyeball, the sliding handle 468 is pushed, so that the soft diaphragm 463 is placed into the eyeball, at this time the soft diaphragm 463 is expanded and pulls the connecting pipe 461 backward, so that the soft diaphragm 463 is in contact with the inner wall of the eyeball, forming a sealing structure of the soft diaphragm 463 and the eyeball, then the hydraulic pipe 32 is connected with the connecting pipe 461.

[0045] Due to the arrangement of the connecting assembly 46, a sealing structure is formed between the eyeball and the hydraulic module, so that when the eyeball is filled with liquid pressure, the probability of liquid leakage between the eyeball and the hydraulic module is reduced, so that more accurate pressure data can be obtained, and the accuracy of the intraocular pressure data is improved.
