A method for use when making mutually different analyses on organic body fluids which, when taken as samples from a patient, are drawn into a so-called vacuum tube 1 which is hermetically sealed by means of a rubber stopper 2 or the like. The device comprises a pressure-equalizing and sample-retrieval cannula 3 having a penetrating pipe 4 with a pointed end intended to penetrate the rubber stopper 2. The other end of the pipe 4 merges with a seating for receiving a cuvette, pipette or like collecting vessel, provides with a suction hose 11 which extends through the pipe 4 and into the vacuum tube 1. The seating is an integral part of a holding device provided with downwardly projecting fixation means 6 which embrace the rubber stopper 2 and hold the cannula 3 in position, so as to enable the vacuum tube 1 to be centifuged with the cannula in position. The seating is constructed to guide accurately and hold firmly that end of the cuvette 9, 10 or pipette which coacts with the seating, so as to enable the vacuum tube 1 with the cuvette or pipette fitted thereto to be handled readily in the form of a unit and connected to a separate pump means 16 for drawing off fluid from the vacuum tube into the cuvette or pipette for analysis purposes.

A method for the analysis of organic body fluids, comprising the steps of: (a) a drawing a sample of an organic body fluid from a patient into a hermetically sealed vacuum tube (1) by suction, (b) inserting a cannula (3) through a rubber stopper (2) sealing an open end of said tube to equalize a remaining partial vacuum in the tube, (c) introducing a suction hose (11) into the tube through the cannula, (d) withdrawing a desired quantity of sample fluid from the tube through the suction hose, (e) passing said sample quantity to a container (10:23) intended therefor, and (f) simultaneously with steps (d) and (e) allowing air to pass down into the vacuum tube to displace the withdrawn sample fluid.
