Abstract: A puncture needle cartridge (1) includes: a lancet body (5) mounted with a puncture needle (3) on a front end side and having a mount (4) on a rear end side; and a plate-like first case (6) and second case (7) covering the lancet body (5) from above and below and arranged slidably back and forth along each other. The puncture needle cartridge (1) is configured such that the first case (6) is slid forward of the second case (7), and in this slid state, the first case (6) and the second case (7) are secured to each other when ejected from the puncture instrument (10). This can make the puncture needle cartridge (1) impossible to mount again on the puncture instrument (10).

Abstract: Provided are a blood collecting puncture device having high safety which can hygienically maintain the inside of a magazine and prevent infection, and the magazine. A blood collecting puncture device has a blood collecting puncture device body removably incorporating a magazine for housing lancets for puncturing human skin. The blood collecting puncture device body has a first housing section for housing not-yet-used lancets and a second housing section for housing used lancets to be disposed of. When a rotor is rotated, individual lancets are sequentially conveyed on a one-by-one basis to a stock position, a puncture position, and a disposal position, and this causes a not-yet-used lancet to be housed in the first housing section and also causes a used lancet to be housed in the second housing section, so that the lancets are separately housed in spaces isolated from each other.

Abstract: A puncturing instrument includes a cylindrical main body case having a puncture aperture on a lower end side; a needle holder provided on a puncture aperture side inside the cylindrical main body case; a first elastic object for moving the needle holder to the puncture aperture side; and a second elastic object for pulling the needle holder back to an upper end side inside the cylindrical main body case, from a state in which the needle holder is moved to the puncture aperture side by the first elastic object. A rotator rotates around a rotation shaft fixed to the cylindrical main body case, and is coupled with a coupling portion of the needle holder on a first one of two sides of the rotator with the rotation shaft interposed therebetween and is coupled with the second elastic object on a second one of the two sides of the rotator.

Abstract: A puncture needle cartridge including a puncture needle, a lancet body adapted to cover part or all of a tip of the puncture needle, a cylindrical puncture needle holder disposed on an outer surface of the lancet body to permit the lancet body to move in an axial direction of the puncture needle; and a protective cap that is separable from the puncture needle holder. The protective cap includes a base adapted to cover an opening in the puncture needle holder, a shaft protruding from the base, and arms mounted on the shaft and configured to abut an inner circumferential surface of the opening in the puncture needle holder by spreading in the opening. A space between tips of the arms is larger than an inside diameter of the opening in the puncture needle holder, and is reduced by elastic deformation when the arms are housed in the opening.
