[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

The puncture needle case (4) has a lancet body (5) and a lancet case (6). The lancet main body (5) has a puncture needle (10), a connecting portion (7) disposed on the second end side and used for connecting with the puncture device (1), and a top end portion of the puncture needle (10) before use. The puncture needle cover part (8), the breaking part (9) that breaks to separate the puncture needle cover part (8) to expose the tip part of the puncture needle (10) when the puncture is performed, and the puncture needle cover part (8) The guide protrusion (12) on the outer peripheral surface is closer to the first end side of the breaking portion (9), and the sliding protrusion (13) is arranged on the second end side than the breaking portion (9). The lancet case (6) has a helical guide portion (14) that applies force to the lancet case (6) in a predetermined direction when it moves relatively in the piercing direction while engaging with the guide protrusion (12). The rotational force; the sliding groove (15), which guides the movement of the lancet case (6) in the piercing direction in the state of engaging with the sliding protrusion (13). The lancet case (6) is attached to the outer periphery of the middle part of the lancet main body (5) in a state where the fracture part (9) is not broken. The puncture needle cover part (8) also has a stopper (33) that restricts the sliding of the lancet case (6) from the state mounted on the middle part to the second end side.

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).
