Patent

CA 2085939

A simple low cost blood sampling device provides a vacuum chamber, a skin suction portion and a piercing and cutting means. The device is sufficiently simple and painless to facilitate its use by the person from whom the blood sample is required, even in the case of a child. The piercing needle is located within the vacuum chamber such that upon the application of vacuum the skin is drawn upwardly against the piercing needle, and being in an engorged condition, due to the suction effect, readily yields the desired blood sample. The local stretching sensation of the skin tends to mask the pain that the penetration of the needle might otherwise produce.
