[0040] figure 1 A piercing device 1 is shown. In addition, the puncture device 1 punctures a human body with a needle to cause blood to flow out, for example, to measure a blood sugar level. The puncturing device 1 is mounted on the front end opening 3 of the elongated main body housing 2 with a figure 2 , image 3 The puncture is performed in the state of the puncture needle cartridge 4 shown.

[0041] In addition, in the following description, "front" means the side (first end side) where puncture is performed by the puncture needle 10, and "rear" means the opposite side (second end side).

[0042] First, the basic configuration and operation of the puncture needle cartridge 4 will be described.

[0043] figure 2 It is an exploded perspective view of the puncture needle cartridge 4 of this embodiment. The puncture needle case 4 has a substantially cylindrical lancet body 5 made of resin and a substantially cylindrical lancet case 6 made of resin.

Abstract

A puncture needle cartridge (4) is provided with a lancet body (5) and a lancet case (6). The lancet body (5) has: a puncture needle (10); a connection section (7) provided on the second end side andconnected to a puncture instrument (1); a puncture needle cover (8) for covering the front end portion of the puncture needle (10) before use; a breakable section (9) which is broken when performing puncturing, thereby separating the puncture needle cover (8) and exposing the front end portion of the puncture needle (10); a guide protrusion (12) provided on the outer peripheral surface of the puncture needle cover (8) at a position on the first end side of the breakable section (9); and a sliding protrusion (13) provided closer to the second end side than the breakable section (9). The lancetcase (6) has: a helical guide section (14) which, when relatively moved in the needle insertion direction while the guide protrusion (12) is engaged, applies to the lancet case (6) a rotational forceacting in a predetermined direction; and a sliding groove (15) for guiding movement in the needle insertion direction while the sliding protrusion (13) is engaged. The lancet case (6) is mounted to the outer periphery of the intermediate section of the lancet body (5) while the breakable section (9) is not broken. The puncture needle cover (8) further has a stopper (33) for restricting the slidingof the lancet case (6) to the second end side from a state in which the lancet case (6) is mounted to the intermediate section.

Description

technical field [0001] The present invention relates to a puncture needle cartridge for puncturing a human body with a needle for blood glucose measurement, for example, and a puncture device to which the puncture needle cartridge is mounted. Background technique [0002] In the past, the puncture needle cartridge is installed on the puncture device, and then the puncture needle cover is removed, and then the puncture operation is performed on the puncture site. [0003] That is to say, this puncture needle cartridge includes: a lancet main body having a connecting portion with a puncturing instrument at the rear end, a puncture needle cover portion at the front end, and a breaking portion in the middle; The broken part of the lancet body is embedded in the lancet body at the front and rear; and the lancet case is provided on the outer periphery of the lancet body (for example, Patent Document 1 below).
