技術說明

現今乾眼症診斷是以淚液試條懸掛於下眼瞼，以接觸的方式量測淚水的分泌量，而過程需要五分鐘的等待，雖然是商用的測試過程，但對於使用者相當不方便，本發明開發一種使用噴氣吹嘴結合熱像儀的裝置，藉由穩定的氣流刺激眼表，誘發淚液分泌，接著使用熱像儀量測眼表的溫度變化，以溫度變化估計淚液分泌量，且可提供穩定的空氣氣流，以熱影像計算出角膜中心區域的溫度變化量，而測得吹氣後眼表因為反射性流淚的溫度變化量，這個顯著的溫度變化量代表噴嘴能刺激流淚，流淚也導致眼表溫度下降，因此可以用來評估淚水的分泌量。 Dry eye diagnosis is a tear test strip suspended in the lower eyelid, measuring the amount of tear secretion in a contact manner, and the process takes five minutes to wait, although it is a commercial test process, but it is quite inconvenient for the user, this The invention develops a device using a jet nozzle combined with a thermal imager to stimulate the ocular surface by a stable airflow to induce tear secretion, and then uses a thermal imager to measure the temperature change of the ocular surface, and estimates the amount of tear secretion by temperature change, and Provide a stable air flow, calculate the temperature change in the central area of the cornea by thermal image, and measure the temperature change of the ocular surface after the blow because of the reflective tear. This significant temperature change represents the nozzle can stimulate tearing, tearing Causes a drop in ocular surface temperature, so it can be used to assess the amount of tear secretion.
