Three bionic simulated eyes and a counterpoint simulated eye are arranged on a panel of an airtight box body with same spacing in a straight line, and the structure of each bionic simulated eye is as follows: a bionic cornea is fixed on a cylindrical base to form an enclosed eye ball cavity, wherein the eye ball cavities of the first bionic simulated eye and the second bionic simulated eye are sealed and respectively have a fixed intraocular pressure value, the eye ball cavity of the third bionic simulated eye is communicated with an air hole through an air inlet pipe, the air inlet pipe is provided with a control valve, and the counterpoint simulated eye is an organic glass hemisphere. The simulated eye device can be used for pressure adjustment according to needs, and reproducing multiple groups of standard intraocular pressure, and has the characteristics of high measurement accuracy and good measurement repeatability.
Description
Technical field
This utility model relates to and has the fixedly simulation human eye of intraocular pressure, especially for the calibration detection apparatus of non-contact tonometer.
Background technology
Non-contact tonometer is a kind of Electronic apparatus of measuring intraocular pressure.Compare with other tonometer, have and directly do not contact patient's cornea, prevent to measure intraocular pressure cause corneal think damage, eye nosocomial infection, reduce advantage such as local anesthesia reaction, and can operate by non-medical staff, be suitable for the census operations of a large amount of crowd's intraocular pressure, now also be applied to clinical more and more.But domestic at present not to the article of corresponding standard verification of non-contact tonometer or assay device instrument, the domestic production that does not also have similar instrument.
The utility model content
The purpose of this utility model provides a kind of non-contact tonometer calibration anthropomorphic dummy's eye device, carrying out the pressure adjustment as required, and reappears many groups standard intraocular pressure value.
This novel purpose is achieved in that a kind of non-contact tonometer calibration anthropomorphic dummy's eye device, be straight line on the panel of airtight casing, by uniform distances three human simulation human eyes and a para-position simulation human eye be installed, each human simulation human eyes structure is: biomimetic cornea is fixed on to form on the cylindrical base and surrounds the eyeball chamber; Wherein, the eyeball chamber of first, second human simulation human eye is sealed and is had fixedly intraocular pressure value respectively, and the eyeball chamber of the 3rd human simulation human eye communicates with a pore through air inlet pipe, and this air inlet pipe is provided with control valve, and para-position simulation human eye is a lucite hemisphere.
The pressure range of accommodation of above-mentioned the 3rd human simulation human eye is 7～50mmHg.
The biomaterial and the thin film technique of this novel analog human eye uses advanced make up the basic shell shape of simulating human eye.Utilize gaseous state to change the basic aerodynamic principle and the equation of gas state of following, can reappear the part physical parameter of eyeball.The simulation human eye can provide standard intraocular pressure and cornea reflecting rate.
Basis is novel to be made up of 3 human simulation human eyes and 1 para-position simulation human eye.Each human simulation human eye has a fixed intraocular pressure value, and the human simulation eyeball partly is made up of cornea, eyeball chamber, pedestal, pore, control valve etc.The operating mechanism process is: the gas of certain pressure is injected in the simulation eyeball, control valve is closed, form the fixedly intraocular pressure of value within the eye.Lucite hemisphere is used for the eyeball para-position.
This novel beneficial effect is:
1,, reappears many groups standard intraocular pressure according to the scope 7～50mmHg of human simulation intraocular pressure.As 10mmHg, 20mmHg, 30mmHg ... (can carry out the pressure adjustment as required).
2, the para-position simulated eye is made up of lucite, and side to light is peculiar mirror surface, uses for regulating the eyeball para-position.
3, adjustable standard pressure is controlled different intraocular pressure values by air valve.
4, the intraocular pressure value of human simulation eye can compare with Goldman tonometer measured value, can be traceable on the national benchmark by the indentation tonometers assay device.
Calibrating (calibration) device of this novel non-contact tonometer makes non-contact tonometer can realize magnitude tracing, and measured value accurately and reliably.The important technological parameters of this device:
Accuracy of measurement: be better than 0.2mmHg;
Measurement reproducibility: be better than 1.0%.
This novel intraocular pressure calibration problem of non-contact tonometer and bionics and physics's problem of modelling of corresponding human eye of having solved.
The simulation human eye of this novel fixedly intraocular pressure is broken through the bottleneck technology of non-contact tonometer meter calibrating, has solved the magnitude tracing problem of non-contact tonometer, for non-contact tonometer widely-used provides technical support.
