Abstract: A low cost safety lancet device for creating a skin incision. The lancet contains a unitarily formed plastic body, thereby making the lancet device easy to manufacture at a low cost. The lancet device includes a blade beam having a cutting blade disposed at one end for generating an incision in a patient's skin. The blade beam is pivotally coupled within the device, engages a beam keeper arm in a first position and disengages the beam keeper arm in a second position. Upon activation of the device, the blade beam member resiliently deflects in a first direction as the beam keeper arm moves from the first position to the second position thereby causing a buildup of a biasing force in the beam member. When the blade beam disengages the beam keeper arm in the second position, the biasing force built up in the beam member causes the beam member to pivot, thereby accelerating the cutting blade through an aperture in the lancet device to incise the user's skin.

Abstract: An apparatus for implementing a skin incision has an incision blade having at least three facets and at least one sharpened apex. Each of the facets narrows down to one of the apexes. A housing having an exterior surface adapted to be placed flush against the skin and an elongated slot located on the exterior of the surface housing the incision blade. A blade pivoting mechanism located in the housing guides the incision blade through the slot. The blade pivoting mechanism has a first end and second end wherein the first end is pivotally coupled to the housing and the second end supports the incision blade. An actuatable depressing mechanism, located within the housing means, engages and holds the blade pivoting mechanism in a set position, preventing the pivotal movement of the blade pivoting mechanism within the housing.

Abstract: A low cost safety lancet device for creating a skin incision. The lancet contains a unitarily formed plastic body, thereby making the lancet device easy to manufacture at a low cost. The lancet device includes a housing having an internal hollow and a blade beam pivotally disposed within the hollow of the housing for generating an incision in a patient's skin. Upon the activation of the device, the blade beam pivots through a predetermined path which causes a blade associated with the blade beam to travel out of an aperture in the housing to incise the patient's skin. The device further includes a trigger for propelling the blade through the path and a cam projection disposed within the housing which cooperates with the trigger to accelerate the trigger through the hollow of the housing thereby causing the blade to accelerate through the aperture of the housing.

Abstract: A low cost lancet device for creating a skin incision. The lancet contains a unistructurally formed plastic body, thereby making the lancet device easy to manufacture at low cost. The plastic body contains a resilient spring loop that attaches an arm element to an opposing base element. The spring loop is curved, therefore the arm element is retained above the base element by the spring loop. A blade is disposed on the arm element. The blade aligns with a slot in the base element so that when the spring loop is compressed, and the arm element is moved toward the base element, the blade extends through the slot in the base element. A protrusion extends from the base element that obstructs the movement of the arm element toward the base element. As a result, when a force is applied to the arm element, the arm element abuts against the protrusion and applies a bias to the protrusion that acts to displace the protrusion.
