Abstract
Device for sampling tear fluid that comprises: an extraction element (202) adapted to be applied on the eye to draw tear fluid therefrom, comprising at least one tube (209) and a distal portion (201) with at least one opening (207), a collection vessel (203), connected to said tube (209), suction means (210) adapted to continuously draw tear fluid from the eye to the collection vessel (203), through the extraction element (202) for a period higher than 10 minutes once the extraction element (202) is in place.
Claims15
Device for sampling tear fluid, characterized in that it comprises:
- an extraction element (202) adapted to be applied on the eye (111) to draw tear fluid therefrom, comprising at least one tube (209) and a distal portion (201) with at least one opening (207),
- a collection vessel (203, 703), connected to said tube (209),
- suction means (210) adapted to continuously draw tear fluid from the eye to the collection vessel (203, 703), through the extraction element (202) for a period higher than 10 minutes once the extraction element (202) is in place.
Method of tear fluid analysis realized by means of a device according to any of the preceding claims, characterized in that it comprises:
- a step (9011) of placing the extraction element (202) on the eye of the subject,
- a step (9013) of continuous sampling of tear fluid by said device for a period higher than 10 minutes once the extraction element (202) is in place, the sampled tear fluid being stored in a collection vessel (203, 703),
- a step (9015) of removing the extraction element (202),
- a step (903) of analysis of the sample, the step (903) of analysis of the sample being performed during and/or after the step (9013) of continuous sampling of tear fluid.
