Adjustable lancet device and method

Abstract

Lancet device that includes a body. A trigger is mounted to the body. A front cover has a skin engaging end that includes a lancet opening through which a lancet needle extends. A holding member is movably mounted within the body and includes a front end a rear end. The front end can be configured to receive a lancet. A stop surface moves with the holding member. A cam disk includes cam surfaces which can be contacted by the stop surface. The cam disk is configured to rotate at least partially. The cam disk rotates about an axis that is not parallel to an axis running through at least one of the lancet opening and the holding member.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to a lancet device having an adjusting capability, and a method of using a lancet device. In particular, the invention relates to a lancet device which utilizes an adjustable depth penetration. Lancet devices are used to penetrate and puncture the skin in order to allow the taking of a blood sample for testing. The present device allows the user to control the depth of this penetration by a simple adjustment mechanism. [0003] 2. Discussion of Background Information [0004] Lancet devices are commonly used to prick the skin of the user so that one or more drops of blood may be extracted for testing. Some users, such as diabetics, for example, may have to test their blood sugar levels several times a day. This may be accomplished by the user using a simple needle. However, this procedure is often problematic for the user since the needle may be difficult to handle. Moreover, controlling the depth ...

Problems solved by technology

However, this procedure is often problematic for the user since the needle may be difficult to handle.

Moreover, controlling the depth of penetration cannot be reliably accomplished without the use of a mechanical device.

Additionally, many users simply cannot perform the procedure owing to either a fear of needles or because they lack a steady hand.

Most lancet devices lack convenient and flexible adjustability.

This, of course, creates the problem of storing the replaceable tips, which if not properly done, may result in their misplacement, damage, contamination, or the like.

The SLAMA device is characterized as a “single bottom” device which employs a threaded design which can be expensive to manufacture.

Further, such a threaded resign is prone to inadvertent setting changes since there is nothing but frictional engagement between the mating threads to maintain the adjustment setting.
