Abstract

A tube for use in the automatic collection of a digital blood sample has its mouth fitted with a resilient detachable funnel member which can carry a capillary cannula and in which is held an absorbent annular plug through which pass and project two incisor lancets.

Claims

1. A device for collecting a percutaneous digital blood sample comprising a tubular body fixedly closed at one end and open at the other end and adapted to collect the blood, a funnel member having a resilient funnel portion and a discharge end comprising an annular portion with a passage therethrough and engaged at its discharge end in the open end oF said body and supported by an annular zone of its lateral surface on the rim of said open end, a mass of absorbent material located within said funnel portion, and at least one incisor lancet in said funnel portion projecting through and beyond said mass and located wholly within said funnel member and means associated with said funnel member to allow air entrapped within said body to vent.

2. A device according to claim 1, and including a capillary tube forming an extension of said annular portion and extending to a location adjacent the closed end of the tubular body.

3. A device according to claim 2, wherein one end of the capillary tube is located within the passage in said annular portion, and is integral with said lancet.

4. A device according to claim 2, wherein the capillary tube is integral with the funnel portion.

5. A device according to claim 1 and including a base plate supported in a lower part of said funnel portion, the lancet being integral with said base plate.

6. A device according to claim 1, wherein the means for allowing entrapped air to vent comprises a passage located in a lower part of the body and communicating with a tubular element integral with said lower part and projecting beyond said part, said device further comprising a closure means for closing said element.

7. A device according to claim 1, wherein the funnel member is secured in a fluidtight manner within the open end of the tubular body and said means for allowing air to vent comprising a passage located in the periphery of said annular portion and the base of said funnel portion.

8. A device as in claim 1 wherein said annular portion is constructed of resilient material and is integral with said funnel portion.
