Definitions

  • the present invention relates to a method according to the preamble of Claim 1.
  • a hose extends from the needle inserted into the blood donor to a blood bag and possible accessories.
  • the bag is typically placed on scales which detect when the correct amount of blood has been taken from the donor, whereupon the hose is automatically clamped tightly in the vicinity of the blood bag, thereby throttling the blood flow.
  • a metal clip is then attached to the hose and the hose is severed between the metal clip and a pair of hemostatic forceps, whereafter the blood bag is taken away for further treatment.
  • the blood is emptied from the bag into open test tubes, by opening the for ⁇ ceps attached to that part of the hose which is connect ⁇ ed to the needle.
  • test tubes Subsequent to having filled one or more test tubes with a given amount of blood, this amount being judged solely by looking at the test tubes, the open test tubes are carried to a bench. Loose stop ⁇ pers are now inserted into respective tubes, which are then shaken on a rotating disc, in a conventional man- ner.
  • the object of the present invention is to fully elimi ⁇ nate the drawbacks of the aforedescribed, earlier known method of procedure, and therewith also to eliminate the risk of infection to the personnel handling the blood taking equipment.
  • Figure 1 is a schematic illustration of a blood taking process and shows the initial stage of a blood sampling process
  • Figures 2 and 3 illustrate schematically a first stage of a blood sampling process
  • Figure 4 illus ⁇ trates the second stage of a blood sampling process
  • Figure 5 illustrates the third stage of a blood sampling process in larger scale.
  • Shown in the drawing is a blood bag 1 and a hose 2 extending from said bag.
  • the needle to be inserted into the blood donor is referenced 3 and is connected to a hose part 4 which is connected to the hose 2 by means of a hose coupling 5 (in the illustrated case a known Luer cap fitting) .
  • the hose part 4 is also provided with a hose clamp 6.
  • Figure 1 illustrates the situation in which the needle 3 is attached to the donor, the hose clamp 6 is open and blood is drained into the bag 1.
  • the hose 2 When the bag has received the correct amount of blood, as indicated by means of the scales mentioned in the introduction, the hose 2 is squeezed together with the aid of some type of clamp which cannot be opened, for instance a metal clip, or the hose may be heat-fused together (as indicated schematically at 7 in Figures 2 and 3).
  • the clamp 6 is activated to seal-off the hose part 4, whereafter the hose 2 is released from the hose part 4 through the agency of the hose coupling 5.
  • the blood bag 1 and hose 2 are removed for further processing.
  • the coupling 5 (Luer cap fitting) of the hose part 4 is then connected to a known sleeve for sub-pressure tube 9 - see Figure 4.
  • a needle-like adapter 10 Inserted in the sleeve in a known manner is a needle-like adapter 10 (see Figure 5) which is surrounded by a stocking 11 which can be penetrated by the needle.
  • the sleeve 9 has a hose coupling (Luer cap fitting) which fits onto the hose coupling 5.
  • a test tube under sub-pressure and fitted with a rubber stopper is inserted in the sleeve, so that the needle 10, which is displaced by the stocking 11, penetrates the stopper 13.
  • the hose clamp 6 is opened and the tube 12 is filled with an exact amount of blood, as a result of the sub-pressure prevailing in the tube.
  • the sub-pressure tube 12 is then removed and the hole made by the needle 10 in the stopper closes automati ⁇ cally as the rubber in the stopper 13 reasserts itself.
  • the tube 12 can now be transported away for further processing of the blood, without risk of blood spilling therefrom.
  • the problem can also conceivably be solved by attaching a so-called Y-coupling to an additional hose for blood sampling purposes.
  • the additional hose must be provided with a fracture pin or a hose clamp and also a Luer cap stopper at one end. This method would enable samples of blood to be taken during the actual blood letting process.
  • the cou ⁇ pling (the Luer cap fitting) may be provided in practice with some form of seal when fitted for delivery, for instance a shrink plastic covering, so that the receiver is able to ascertain whether or not the coupling is intact and therewith sterile.

Abstract

Technique d'échantillonnage de sang mise en ÷uvre conjointement avec des procédés de prélèvement de sang et de plasmaphérèse manuelle, consistant à utiliser une poche de sang (1) et un tube de raccordement (2, 4), ainsi qu'une aiguille (3) destinée à être introduite dans le corps du donneur de manière classique. La technique se caractérise en ce que le tube est pourvu d'un raccord (5) de tube et en ce qu'un clamp (6) de tube est disposé entre le raccord et l'aiguille. Au cours de l'échantillonnage de sang, le tube (2, 4) est refermé des deux côtés du raccord (5), puis celui-ci est libéré, et la partie du raccord reliée à la partie du tube (4) recevant l'aiguille, est reliée à un manchon à sous-pression ou analogue, dans lequel un ou plusieurs tubes à sous-pression ou analogue sont introduits en séquence afin de collecter des échantillons de sang.
