Embodiment 1

[0029] Such as figure 1 As shown, the present invention provides a portable intraocular pressure detector, comprising:

[0030] A gas generating device ( figure 1 Middle is elastic balloon 1);

[0031] A main gas flow channel 2 communicating with the gas generating device;

[0032] A bowl-shaped detection cover 9 communicated with the main airflow channel 2, the inner wall of the bowl-shaped detection cover is provided with a pressure sensor 4 for measuring the pressure of the reflected airflow of the eyeball;

[0033] The controller and circuit structure connected with the pressure sensor (not shown in the figure, the circuit board is arranged on the bowl-shaped detection cover).

[0034] Preferably, in the portable tonometer of the present invention, the main airflow channel 2 communicates with an auxiliary airflow channel 3, and the auxiliary airflow channel 3 is provided with a pressure sensor 5 for measuring airflow pressure.

[0035] In the portable intraocular press...

Embodiment 2

[0037] Such as figure 2 As shown, the difference from Embodiment 1 is that in the portable intraocular pressure detector of the present invention, the gas generating device can be a cylinder 6, and a movable piston 7 is arranged in the cylinder 6, and There is a button 8 for controlling the stroke and speed of piston movement. During use, by pressing the button 8, the mechanical structure can be used to automatically inject gas to the eyes.

[0038] Preferably, in the portable intraocular pressure detector of the present invention, the controller sends the intraocular pressure value as a digital signal to an external display device through WIFI or Bluetooth wireless signals. The external display device is a dedicated display device, a mobile phone or a tablet computer. It is convenient for users to check the intraocular pressure status, and can also mark the change curve of intraocular pressure within a day or within a period of time according to the statistical software. ...

Abstract

The invention discloses a portable intraocular pressure detector which comprises a gas generation device, a main gas flow channel communicated with the gas generation device, a bowl-shaped detection cover communicated with the main gas flow channel, a controller and a circuit structure, wherein pressure sensors used for measuring eyeball reflection gas flow pressure are arranged on the inner wall of the bowl-shaped detection cover, and the controller and the circuit structure are connected with the pressure sensors. The invention further discloses an intraocular pressure detection method based on the device. The portable intraocular pressure detector and the intraocular pressure detection method are suitable for domestic intraocular pressure monitoring, the eyes can be effectively protected, and glaucoma can be prevented.

Description

technical field [0001] The invention relates to a medical device for detecting intraocular pressure, in particular to a portable intraocular pressure detector. The invention also relates to a method for detecting intraocular pressure. Background technique [0002] Intraocular pressure refers to the pressure of the contents of the eyeball on the eyeball wall. It is an important parameter that can be quantitatively controlled in the treatment of glaucoma. It plays an important role in the diagnosis of glaucoma. Tonometers are generally used to measure intraocular pressure. There are many kinds, among which the non-contact tonometer is represented by the air jet tonometer developed by Bernard Grolman. This tonometer optically detects applanation of the cornea when air is sprayed on the cornea of ​​the subject's eye from a nozzle about 11 mm away from the cornea. A contact Goldman-type tonometer calculates intraocular pressure values ​​by calibrating the time until applanation...
