Disposable lancet device
First Claim
1. A disposable lancet device for piercing human skin comprising:
- a lancet housing;
a lancet body displaceably supported by the housing and having a piercing tip which is concealed within the housing in a rest position of the body;
an operator integral with or connected to the lancet body for manually displacing the lancet body to expose the piercing tip; and
a return against which the lancet body operates as it is manually displaced to expose the piercing tip whereby the return automatically retracts the lancet body to its rest position when the manual displacement force is removed from the operator wherein the operator is readily manually separable from the lancet body after use to prevent subsequent manual displacement of the lancet body from its rest position.

Abstract
A disposable lancet device adapted to pierce human skin sufficiently to let a small quantity of blood for testing. The device includes a lancet housing, a lancet body displaceably supported by the housing, and a piercing tip concealed within the housing in a rest position. The piercing tip can be integral with the lancet body or attached thereto. The device also includes an actuator for manually displacing the lancet body to expose the piercing tip under applied force and a return mechanism that returns the lancet body to the rest position when the manual displacement force is removed from the actuator. The actuator can be disabled to inhibit further manual displacement of the lancet body and exposure of the piercing tip. Thus, the piercing tip can be repeatedly exposed if desired, but can also be disabled once further use is no longer desired.

25. A multi-use, safety lancet device comprising:
-
a lancet housing of a first length; a lancet body displacably positioned within the lancet housing; a piercing tip attached to a first end of the lancet body such that the piercing tip and lancet body together are of a second length less than the first length; a return biasing the lancet body and piercing tip to a concealed position wherein the lancet housing covers the piercing tip; and an actuator operating the lancet body between the concealed and an operational positions wherein the piercing tip is exposed and wherein the actuator can repeatedly change between the concealed and operational positions and wherein the actuator is also disablable so as to inhibit further achievement of the operational position. - View Dependent Claims (26, 27, 28, 29, 30)
