    Abstract: A blood sampling device (10, 10') including a housing (12, 12') having an open end portion (16,16') and an inner chamber (18, 18') adjacent to the open end portion (16, 16'). A plunger (40, 40') is slidably mounted within the chamber (18, 18') for supporting a lancet (28, 28') having a lancet blade extending therefrom. The plunger (40,40') is movable between a retracted position disposing the lancet blade (29, 29') away from the open end portion (16, 16') and an unreacted position disposing the lancet blade (29, 29') to extend beyond the open end portion (16, 16'). The device (10, 10') includes a gasket (30, 30') for prefecting a seal between the housing (12, 12') and the plunger (40, 40') for creating a vacuum within the inner chamber (18, 18') when the plunger (40, 40') is moved from the unretracted position to the retracted position to thereby draw blood from the lanced skin.

    Abstract: A liquid sample needle assembly is provided. The assembly includes a housing with a sample receiving chamber having translucent or transparent walls for determining whether access to the sample source in question has been obtained. The invention utilizes a highly absorbent material in a form which allows venting of gases displaced from the housing chamber by the liquid sample being obtained, which material expands upon contact with the liquid sample to provide a liquid impervious barrier. The absorbent material is in a separate sleeve-like form of a compacted tablet sleeve for rapid and easy insertion between the two hub parts forming the assembly housing. The improvement in this invention includes the use of an integral tapered post for seating the tablet to maintain it precisely concentric in the housing and on the post for causing each increment of the tablet to respond equally to an introduced sample. The arrangement herein is particularly appropriate for mass production techniques in that two housing parts may have inserted therein the separately formed tablet sleeve. r

    Abstract: A blood collector (1) has a cylindrical body (2) having a closed end (2a) and an open end (2b), and a hollow body (7) which is arranged at the closed end (2a) of the cylindrical body (2) and which has a hole (6) communicating with an interior of the cylindrical body (2). A columnar body (3) is arranged within the cylindrical body (2) to be in tight contact with an inner wall thereof and a distal end of which defines a blood collection space (5) with the closed end (2a) of the cylindrical body (2). Further, the columnar body (3) has a hole (10) which allows the blood collection space (5) to communicate with the outside. A freeze-dried blood anticoagulant mass (13) is placed inside the blood collection space to cover an inner surface of the closed end (2a) of the cylindrical body (2) and to block the hole (6) of the hollow body (7). A filter (11) is arranged to laterally cross the hole of the columnar body (3). The filter (11) is permeable to gases and impermeable to blood at least before being brought into contact with blood.

    Abstract: A disposable lancet assembly is provided, including a housing serving as a lance-holder guide, a lance holder body reciprocable in the housing guide, and a flat-bladed lance mounted in one end of the lance holder body. Included in the invention are integral strategically positioned abutments which serve dual functions providing snap-action drive for the lancet, together with steps for lance movement control. Also included are integral resilient means on the lance holder body providing damping of the lance drive in the puncture direction with automatic withdrawal of the lance into the housing.

    Abstract: A lancet device for performing a pricking operation comprises a barrel (36) which is closed at one end by a finger guard plate (43) having a centrally positioned hole (42). Prior to use, the hole (42) is closed by a centrally disposed axially protruding spigot (54) found on the inside of a cap (40). In use, the cap is removed and the spigot (54) is inserted into the other end of the barrel (36) to bear against a shank 44 of a needle assembly 16 is secured to the periphery of a hole (46) in an end plate (48). A finger to be pricked is placed against the finger guard plate (43) and a thumb is placed over the cap (40). Pressure between the thumb and finger causes the spigot (54) to break the attachment between the shank of the needle and the periphery of the hole (46) to allow the needle assembly to be projected through the barrel (36) under the force exerted by a compressed spring (16). A needle (34) of the assembly projects through the hole (42) to prick the finger, before being retracted into the barrel (16) as a result of the spring (16) having overstretched itself past its null position.
