Abstract
There is provided a microneedle bio-sampling apparatus including: an bio-sampling body enabling a microneedle to be inserted into human skin; and a blocking unit installed in the bio-sampling body and preventing the microneedle from moving to the skin again to prevent repeated bio-sampling by the microneedle. Since the microneedle bio-sampling apparatus is configured to prevent repeated bio-sampling of a single-use microneedle, secondary infection to other part of a human body or a different person due to blood, human anatomy, or the like, that may remain in a microneedle after the microneedle is used once otherwise in case of repeated bio-sampling of a microneedle, can be prevented.
Claims6
A bio-sampling apparatus comprising:
- a bio-sampling body configured to enable insertion of a needle into a sample;
- and
- a blocking unit installed in the bio-sampling body,
- wherein the blocking unit is configured to prevent the needle from repeatedly moving into the sample,
- wherein the bio-sampling body comprises:
- an external cover having a hollow connecting openings formed in a plurality of sides of the external cover;
- a pressing unit having one side in which the needle is installed, wherein the pressing unit is configured to move toward the sample along the hollow;
- and
- an elastic unit fixed to the external cover, connected to the pressing unit,
- wherein the elastic unit returns the pressing unit, having moved toward the sample, to an original state of the pressing unit when pressure applied to the pressing unit is removed,
- wherein the blocking unit comprises:
- a film member fixed to the pressing unit and surrounding the needle;
- a film cover covering the film member and having a size corresponding to an edge of the pressing unit;
- and
- a blocking member fixed to the external cover and configured to elastically press the film cover, penetrating through the film member to extend inwardly when the film cover is removed from a position covering the film member, and
- wherein the blocking member prevents the pressing unit from repeatedly moving toward the sample, thereby preventing repeated bio-sampling.
