Abstract

A micropore forming system comprising: a microneedle chip having microneedles for forming micropores in a skin of a living body; a chip container for detachably housing the microneedle chip; and a micropore forming device for detachably holding the microneedle chip and for contacting the microneedles of the microneedle chip to the skin.

Claims

1. A chip container comprising:

a first rim that delineates a first opening through which an unused microneedle chip held in the container is removable, the first opening being opened in a direction parallel to an axis of the container;

a first holder configured to removably hold the unused microneedle chip in the container, the first holder being formed in the first opening so as to allow access through the first opening to the unused microneedle chip held in the container and allow removal of the unused microneedle chip from the container, wherein the first rim is formed with one of a projection and a recess, which is in agreement with the other thereof formed on the microneedle chip;

a second rim that delineates a second opening through which a used microneedle chip is only insertable for storage in the container and not removal from the container, the second opening being opened in a direction parallel to the axis of the container and opposite to the direction of the first opening; and

a second holder configured to unremovably hold the used microneedle chip in the container, the second holder being formed in the second opening so as to receive the microneedle chip through the second opening and prohibit removal of the microneedle chip from the container, wherein the second holder comprises at least one beam which is formed with a complementary key structure engageable with a key structure of the microneedle chip, the complementary key structure of the at least one beam and the key structure of the microneedle chip being a key hole and a key projection engageable with each other, and the at least one beam is flexed to lead the key structure of the microneedle chip to engagement with the complementary key structure of the at least one beam and flexed back upon engagement between the complementary key structure and the key structure to secure the engagement.

2. The chip container according to claim 1, wherein the container is tubular in shape having the axis going therethrough, and the first and second openings are opened in the opposite directions coaxial along the axis of the container.

3. The chip container according to claim 1, wherein the first holder comprises a plurality of supports that support the unused microneedle chip in such a manner as to allow removal of the unused microneedle chip through the first opening from the container.

4. The chip container according to claim 1, wherein the plurality of supports support the microneedle chip at intervals to allow access to the microneedle chip through the first opening between adjacent supports.

5. The chip container according to claim 3, wherein the supports each comprise a pillar erected in the first opening for contact with the microneedle chip.

6. The chip container according to claim 1, wherein the second holder comprises at least one release piece provided in the second opening and shaped to at least partially surround, the microneedle chip to prohibit access to the microneedle chip held by the second holder in the container.

7. A chip container kit comprising:

a microneedle chip comprising microneedles for forming micropores in skin of a living body; and

a chip container comprising;

a first rim that delineates a first opening through which the unused microneedle chip held in the container is removable, the first opening being opened in a direction parallel to an axis of the container;

a first holder configured to removably hold the unused microneedle chip in the container, the first holder being formed in the first opening so as to allow access through the first opening to the unused microneedle chip held in the container and allow removal of the unused microneedle chip from the container, wherein the first rim is formed with one of a projection and a recess, which is in agreement with the other thereof formed on the microneedle chip;

a second rim that delineates a second opening through which the used microneedle chip is insertable for storage in the container, the second opening being opened in a direction parallel to the axis of the container and opposite to the direction of the first opening; and

a second holder configured to unremovably hold the used microneedle chip in the container, the second holder being formed in the second opening so as to receive the microneedle chip through the second opening and prohibit removal of the microneedle chip from the container, wherein the second holder comprises at least one beam which is formed with a complementary key structure engageable with a key structure of the microneedle chip, the complementary key structure of the at least one beam and the key structure of the microneedle chip being a key hole and a key projection engageable with each other, and the at least one beam is flexed to lead the key structure of the microneedle chip to engagement with the complementary key structure of the at least one beam and flexed back upon engagement between the complementary key structure and the key structure to secure the engagement.
