962,356. Pipette assemblies. H. W. GERARDE. Feb. 16, 1962, No. 6103/62. Heading SIX. A pipette assembly for preparing blood count solutions comprises a capillary tube 15 held in a tubular mounting 16 and a reservoir 17 having an opening and a flexible and resilient part, the reservoir containing a volume of diluent 24, and the mounting being arranged to fit in and seal the reservoir with the tube extending into the reservoir, whereby in operation the capillary tube is filled with blood by capillary action, the flexible and resilient part of the reservoir is squeezed and the tube is inserted into the reservoir so that the mounting closes the opening and the blood is sucked into the diluent. In a preferred embodiment the other end of the mounting tube is then connected to the reservoir to discharge the sample through the capillary tube. As shown in Fig. 2, to which the above numerals refer, the reservoir may be sealed by plug 26 with enlarged head portion 25 displaceable into the reservoir to form a mixing head. Or alternatively, as shown in Fig. 10, the reservoir may be sealed by adaptor unit 10 mounting a lancet 41 to prick the skin. |
