Description
Technical field
This utility model relates to a kind of jet eye pressure detection device based on graphene conductive film.
Background technology
Intraocular pressure formed wall of eyeball applied pressure by eyeball content; when intraocular pressure exceedes the tolerant top level of oneself eyeball institute; a series of damage of visual functions such as optic nerve lesion, defect of visual field and visual deterioration can be caused; therefore, intraocular pressure is detected so that in time treatment and to alleviate ocular hypertension extremely important to vision protection.
Therefore, various intraocular tension testing device has occurred, the detection appearing as intraocular pressure of these devices provides conveniently, and for glaucomatous prevention plays a good role, but existing intraocular tension testing device also has some shortcomings:
1. intraocular tension testing device conducting transmission part adopts metallic film mostly, and cost is higher, and along with the lengthening of service time, may get rusty, affect conducting effect;
2. intraocular tension testing device needs directly to contact with eyeball, may cause a series of damage to eyes.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of jet eye pressure detection device based on graphene conductive film, sanitation and hygiene, it is low that conductive film has cost, effective advantage.
The purpose of this utility model is achieved through the following technical solutions: based on the jet eye pressure detection device of graphene conductive film, it comprises calibrating installation and checkout gear, and described calibrating installation comprises center from left to right successively and has the slit plate of perforate, air nozzle, the first lens, the second lens and photo-sensitive cell; Described checkout gear comprises infrared light supply, light source receiving device, transparent graphene conductive film, main control MCU module and display screen; Described light source receiving device is connected with main control MCU module by transparent graphene conductive film, and the outfan of main control MCU module is connected with display screen.
The center of described slit plate, air nozzle, the first lens, the second lens, photo-sensitive cell is on same level line.
Described main control MCU module comprises MSP430 single-chip microcomputer.
Described light source receiving device comprises receptor and optical pickocff.
The beneficial effects of the utility model are: (1) conducting transmission part adopts transparent graphene conductive film, and cost is low, effective, and service time is long; (2) do not need directly to contact with eyeball, sanitation and hygiene, do not damage eyes; (3) there is display, do not need to connect external equipment, directly can show intraocular pressure value in checkout gear.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, based on the jet eye pressure detection device of graphene conductive film, it comprises calibrating installation and checkout gear, and described calibrating installation comprises center from left to right successively and has the slit plate 2 of perforate, air nozzle 3, first lens 4, second lens 5 and photo-sensitive cell 6; Described checkout gear comprises infrared light supply 10, light source receiving device 11, transparent graphene conductive film 7, main control MCU module 8 and display screen 9; Described light source receiving device 11 is connected with main control MCU module 8 by transparent graphene conductive film 7, and the outfan of main control MCU module 8 is connected with display screen 9.
The center of described slit plate 2, air nozzle 3, first lens 4, second lens 5, photo-sensitive cell 6 is on same level line.
Described main control MCU module 8 comprises MSP430 single-chip microcomputer.
Described light source receiving device 11 comprises receptor and optical pickocff.
Before carrying out intraocular pressure test, first calibrate, make photo-sensitive cell 6 center be obtained the image of the eyeball 1 of testee by the perforate of slit plate 2, and by adjustment eye position, make center and photo-sensitive cell 6 center of eyeball 1, namely the center of whole calibrating installation is on same level line; Then air nozzle 3 is jet to eyeball 1, infrared light supply 10 transmitted beam, reflected signal is received by the receptor of light source receiving device 11 after ocular reflex, the signal of telecommunication is converted to by optical pickocff, be transferred to main control MCU module 8 by transparent graphene conductive film 7 again, calculate through main control MCU module 8 and be transferred to display screen 9 after intraocular pressure numerical value and show.
