Puncture needle cartridge for blood collecting device

There is provided an injector having an improvement in a linear launching profile. The injector of the present invention is used for launching a lancet to provide a pricking. The injector of the present invention comprises a plunger capable of launching the lancet in a pricking direction, an injector housing which surrounds the plunger, and an injector cap capable of being attached and detached with respect to the injector housing. In particular, an inner face of the injector cap is provided with a rib, and the rib and the plunger moving for the pricking are capable of contacting with each other.

Injector

Blood collecting device

A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. The lancet comprises a lancet body, lancet cap and pricking needle. The pricking needle is in both the lancet body and lancet cap. The trigger part has a pair of arms positioned inside the holder. The launching spring is attached to the lancet body. The lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is compressed before a pricking operation. The trigger part cannot be pushed toward the inside of the holder before the lancet cap is removed, but can be pushed toward the inside of the holder after the cap is removed. The lancet body warps when pressed to release the secured lancet body.

Lancet pricking device

There is provided a process of producing a lancet which suppresses curving (or flexing) of the front end portion of the pricking member. In the production of a lancet by injection molding of a resin with a pricking member inserted in a mold, upon forming at least a portion of a lancet cap in which portion a molten resin supplied to the mold surrounds a front end portion of the pricking member, a mold is used which is configured such that at least a portion of the molten resin which forms said portion of the lancet cap flows along the front end portion including a leading end of the pricking member toward its leading end.

Lancet, method for manufacturing the lancet, and mold for the method

A lancet pricking device comprises a lancet, a launching spring, a trigger part and a holder housing the lancet, launching spring and trigger part. The lancet comprises a lancet body, lancet cap and pricking needle. The pricking needle is in both the lancet body and lancet cap. The trigger part has a pair of arms positioned inside the holder. The launching spring is attached to the lancet body. The lancet body is secured to the arms of the trigger part by an abutment of the lancet body on the arms such that the launching spring is compressed before a pricking operation. The trigger part cannot be pushed further into the holder before the lancet cap is removed, but can be pushed further into the holder after the cap is removed. The pair of arms warp when pressed to release the secured lancet body.

Lancet

A lancet assembly includes a lancet, a lancet engaging part, and a lancet case housing the lancet and the lancet engaging part. In the lancet assembly of the present invention, the lancet engaging part and the lancet cap are disposed such that they are capable of making contact with each other. When the lancet engaging part is forced to move forward with respect to the lancet in a pricking direction, the lancet cap is pressed by the lancet engaging part, and thereby the bridging component is broken so that the lancet cap is separated from the lancet body. When the lancet engaging part is forced to further move forward, the separated lancet cap moves to the position off a pricking pathway of the pricking component within the lancet case.
