非接触式眼压计检定用模拟人眼装置的设计

A Design of Standard Eye Device for Non-contact Tonometer

针对国内非接触式眼压计由于检测技术问题,长期无法强制监管的现状,提出一种模拟人眼装置的设计,采用仿生人眼角膜巩膜,自制模拟人眼腔体,大小与真实房水容积相近,并设有连续调节装置,利用活塞丝杆调控内部仿生房水压力,通过植入压力传感器读取内部液体压力数值,模拟人眼与真实眼压情况接近,对非接触式眼压计的量值溯源具有借鉴意义。

According to the status that non-contact tonometer （NCT） has not been long-term under mandatoryregulation due tothe measuring technical problems, a design of standard eye device has been presented, where bionic cornea and sclera are applied and the cavity size of standard eye is close to the real volume of aqueous humor in human eye. The pressure of standard eye can be continuously adjusted through a piston screw, and the pressure value can be read through the implanted pressure sensor. Such standard eye device has effectively simulated the real intraocular status of human eye, which may have certain significance for the traceability of NCT.
