Abstract:
The invention comprises a blood lancet device for puncturing the fleshy part on the inner side of a finger tip, or an ear lobe, in order to draw blood for a hemoglobin test, or other type of blood test and which is completely sanitary to avoid any possibility of contamination of the blood drawn for testing. The device includes a finger grip element to be held by a user, with a surface adapted to be engaged with the fleshy finger tip pad, or ear lobe, and a hinged striker element pivotally mounted on the device and spring actuated to drive a sharp puncturing element secured on the striker, into such pad, with a thumb piece on the striker for drawing it back to a cocked position and having a twist-off or tear away protective element for maintaining the sanitary condition of the puncturing element until it is to be used. The striker element is flexible and the finger grip element is provided with an upstanding projection on the top surface, which the striker contacts and about which the striker flexes when it is spring actuated downwardly about its pivot, whereby the puncturing element is thrust downwardly below the bottom surface of the finger grip element to puncture the flesh and then be retracted upwardly when it rebounds to dispose the puncture element substantially above such bottom surface in a withdrawn position.
