PCT No. PCT/SE85/00014 Sec. 371 Date Aug. 23, 1985 Sec. 102(e) Date Aug. 23, 1985 PCT Filed Jan. 15, 1985 PCT Pub. No. WO85/03350 PCT Pub. Date Aug. 1, 1985.A device for taking and dispensing blood samples for the purpose of determining blood sedimentation, comprising a sampling tube (6) which is sealed against the ingress of air and liquid by means of a rubber stopper (8) and in which a partial vacuum either prevails or can be created by means of a displaceable plunger (14) arranged in the sampling tube. The sampling tube contains a given quantity of an anti-coagulant (9), and connected to the sampling tube (6), preferably integral therewith, is a pipette tube (7) having an inner diameter and a length conforming to the standards prescribed for the sedimentation reaction. According to one embodiment, the pipette tube (7) is sealed against the ingress of air and liquid and encloses a partial vacuum. One connection (10,11) between the interior of the sampling tube (6) and the interior of the pipette tube (7) is normally closed, but can be selectively opened, preferably by rotating the rubber stopper (8), so that a sample can be transferred from the interior of the sampling tube (6) to the interior of the pipette tube (7) under the influence of a partial vacuum in the pipette tube. Simultaneously herewith there is opened a connection (12,13) between the interior of the sampling tube (6) and the surrounding atmosphere, this connection suitably being normally closed. In an alternative embodiment, the pipette tube (7) is open at one end thereof and the sample is transferred from the sampling tube to the pipette tube through the connection therebetween, under the influence of an overpressure generated in the sampling tube with the aid of a plunger arranged for axial movement therein. |
