<p>Improvement on the pivoting arm (7) of an automatic lancet (1). Generally an automatic lancet (1) is comprised of a housing (2A and 2B) having a spring loaded pivoting arm (7). The arm has a cylindrical holder (4) at the operating end which holds a needle (61) encased in a plastic carrier (60). Upon releasing the spring (9), the needle (61) pierces the patient's finger producing a blood sample. To replace the needle (61) generally requires pulling the old needle out with one's fingers and pushing a new one in. The present invention improves the cylindrical holder (4) by adding a plunger (11) inside it. This enables the user to push the old needle (61) out without the necessity of grabbing or touching the old needle. Thus, safety for the medical technician is greatly enhanced.</p> |
