Embodiment Construction

[0060] Preferred Mode for Carrying Out the Invention

[0061] Hereinafter, embodiments embodying the present invention will be described based on the drawings.

[0062] First, see Figure 1 to Figure 12 , the overall structure of the micropore forming device 1 according to one embodiment of the present invention will be described.

[0063] like figure 1 As shown, a micropore forming device 1 according to an embodiment of the present invention includes a microneedle 2 and a needle holder 3 that detachably holds the microneedle 2 . The micropore forming device 1 is equipped with a sterilized microneedle head 2, and the microneedle 21 of the microneedle head 2 collides with the skin of a living body (for example, the skin of a human body), and the microneedle 21 is placed on the skin of a living body A device that forms suction holes (micropores) for body fluids. Specifically, the micropore forming device 1 penetrates the skin to form a plurality of fine extraction holes that...

Abstract

The present invention further provides the use of a detached without using a member, can be more easily to conduct the task that in a micropore to remove the fine needle forming device, a fine needle and a needle holder. The micropore forming device (1) comprises a fine needle head (2) and a needle holder (3), the fine needle head (2) comprises a cylindrical needle body (20), a plurality of fine needle (21) and a side projecting portion projecting (22) of a needle body (20). The needle holder (3) includes a needle holding portion (40) and a engagement releasing portion (50), the needle holding portion (40) having an engaging position (P2) from the guide (41) of the guide protrusion (22) of the inlet position (P1) to the engagement position (P2) and the projecting portion (22) engaging and retaining the fine needle (2). The engagement releasing portion (50) with respect to the needle holding portion (40) is movably disposed, with the projecting portion (22) from the engagement position contact (P2) to move the needle in the needle (2) and the needle holding portion (40) for releasing the engagement.

Description

technical field [0001] The present invention relates to a micropore forming device, a microneedle head, and a needle holder, and more particularly to a micropore forming device, a microneedle head, and a needle holder for forming micropores on the skin of an examinee using a microneedle. Background technique [0002] Conventionally, a micropore forming device including a microneedle and a needle holder is known (for example, see JP2007-236844A). [0003] JP2007-236844A discloses a micropore forming device including a microneedle and a needle holder detachably holding the microneedle. In this microhole forming device, the microneedle tip is attached to the needle holder by fitting the needle accommodating member into the opening of the needle holder while the microneedle tip is housed in the needle holder. After use, the microneedle is detached from the needle holder and returned to the needle holder by fitting the needle holder into the opening of the needle holder with the...
