ABSTRACT:
A lancet device and associated method used for obtaining a blood sample from a patient. The lancet includes a safety housing adapted to be placed against some area of the patient's skin, such as a finger. A slotted aperture is formed through the safety housing in the region of the housing placed against the skin. An invertible spring member is disposed within the safety housing. The invertible spring member is a curved structure that automatically inverts into a generally oppositely curved orientation when the invertible spring member is flattened by a predetermined degree. The cutting blade used to make the incision is coupled to the invertible spring member within the safety housing. A manipulative element supports the invertible spring member and blade within the safety housing. The manipulative element is held at a set position in relation to the safety housing until a threshold force is applied to the manipulative element. Once the threshold force is applied, the manipulative element rapidly advances into the safety housing pushing the spring member and the blade against the wall of the safety housing that is positioned on the patient's skin. The blade extends through the slotted aperture in the safety housing and makes the desired incision. The spring member is then flattened in between the housing and the advancing manipulative element. Accordingly, the spring member is caused to change into its inverted configuration which retracts the blade permanently back into the safety housing.
