Method and system for providing a single-use safety lancet
First Claim
1. A one-time use lancet system comprising:
- a body;
a spring coupled to the body;
a keeper having a deformable member;
wherein the keeper is part of the body anda core for supporting a lancet and having an end coupled to the spring, the core further comprising a first latch for engaging the deformable member when the lancet system is in an armed state;
the deformable member being fractured after one use of the lancet system which prevents any subsequent arming of the lancet system.

Abstract
A one-time/single use safety lancet system includes a body; a spring coupled to the body; a keeper having a deformable member; and a core for supporting a lancet and having an end coupled to the spring. The core further has a first latch for engaging the deformable member when the lancet system is in an armed state. The deformable member of the keeper is fractured after one use of the lancet system which prevents any subsequent arming of the lancet system. The keeper may be made part of the lancet body. The core may include a second latch, wherein the second latch permanently deforms or fractures the deformable member of the keeper after the single, one-time arming of the safety lancet system.

7. A method for providing a single-use lancet system, the method comprising:
-
providing a body for housing a plunger, a lancet, a core, a biasing member for the core, a trigger, a first latch, a second latch, and a keeper for engaging the first and second latches; providing a deformable member for the keeper that may engage with the first and second latches; moving the core with the plunger such that the deformable member engages with the first latch to place the lancet system in an armed state; moving the keeper to disengage first latch from the deformable member of the keeper; launching the core past the keeper with the biasing member and through the body such that lancet exits the body; elevating the keeper to its rest state once the core moves past the keeper when the lancet strikes the tissue and after compression force is removed from trigger; moving the core through the body towards the biasing member with the plunger such that the second latch slides along the keeper and engages the deformable member of the keeper; and permanently fracturing the deformable member with the second latch as core is moved into the body. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
