Patent DE-3069078-D1 (DE)
Title: Liquid sample collector device
Inventor: TURNER ROBERT CHARLES
IPC: B01L3/00
Filed: 1980-11-14
Granted: 1984-10-04
Abstract: A collector device for collecting, metering and holding a small sample of liquid, e.g. a drop of blood taken from a finger prick, comprises a vessel (10, 11 or 10A, 52A) provided with an opening (20 or 20A) closed by a plug (22 or 22A), and a screwthreaded cap (15 or 15A) having a protruding spigot (30 or 30A) which, when the cap is screwed fully onto the vessel, enters the opening and pushes the plug down into the interior of the vessel. The plug is formed at its outer end with an outwardly facing recess (24), e.g. part- spherical, and the spigot is formed at its end which enters the opening with a tapering conical formation (31) adapted to enter the recess (24). In use, with the cap (15 or 15A) removed the recess (24) is filled with a quantity of liquid, the cap is then partly replaced to cause the spigot (30 or 30A) to abut the end of the plug (22 or 22A) so that its conical formation (31) enters the recess (24) and displaces excess liquid therefrom, trapping a metered sample of liquid of predetermined volume, less than the volume of the recess, in the space defined between the abutted ends of the plug and spigot. The cap (15 or 15A) is then screwed fully home causing the spigot to push the plug down until it falls into the vessel, thus transferring the metered liquid sample into the vessel whose opening (20 or 20A) is now closed by the spigot (30 or 30A). The device enables a metered quantity of blood to be collected and transferred into the closed vessel for subsequent analysis, without contamination of the exterior of the device by the blood, and without the use of delicate metering devices such as capillary tubes to meter the blood sample. A latch connection (55A, 59A) may be provided between the cap (15A) and a removable lid (52A) of the collection vessel whereby when the cap is unscrewed it slowly withdraws the lid and opens the vessel.
