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