Title:
TEAR GLUCOSE TEST DEVICE AND PRODUCTION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/061471
Kind Code:
A1
Abstract:
A tear glucose test device comprises a tear glucose test strip and a support assembly (4), wherein the tear glucose test strip comprises two identical test strip units (a, b) connected in parallel in a first direction; the test strip units (a, b) each comprise a tear sampling area (1), a hydrophobic isolation zone (2), and a holding portion (3); the hydrophobic isolation zone (2) is located between the tear sampling area (1) and the holding portion (3); the two test strip units (a, b) are connected at the holding portion (3), and are separated between the tear sampling area (1) and the hydrophobic isolation zone (2); the tear sampling area (1) is configured to sample tears and react same with a glucose test reagent to test tear glucose, the hydrophobic isolation zone (2) is configured to prevent further diffusion of the tears, and the holding portion (3) is configured to be bonded to the support assembly (4) so as to enhance the rigidity of the tear glucose test strip; and the first direction is a width direction of the elongated tear sugar test strip. The tear glucose test device can rapidly test tear glucose, is suitable for non-professionals to regularly test the tear glucose, can qualitatively measure the tear glucose for prevention of diabetic retinopathy, and can also quantitatively measure the tear glucose by means of the parallel relationship between the tear glucose and blood glucose.
