ABSTRACT:
An apparatus for direct blood transfusion which comprises two needles with tubes connected thereto. One needle is introduced into the donor's blood system, while the other into the recipient's blood system. In order to provide for the delivery of blood from the donor to the recipient via said tubes, the apparatus is equipped with a vessel containing a medicamental liquid compatible with blood and mounted at a height sufficient for creating a hydrostatic head of the medicamental liquid exceeding the blood pressure in the recipient's vasculature. The apparatus also comprises a distributing means built around at least four proportioning vessels vertically mounted in a housing and rigidly coupled therewith. The housing is disposed between the upper and lower disks of a stator in coaxial relationship therewith. The housing is made rotatable in one direction with respect to the stator. The upper disk and the lower disk of the stator each have at least four holes formed therein. As the housing turns, each of the proportioning vessels passes successively through at least four positions. In each position each proportioning vessel is so disposed with respect to the stator that its inlet and outlet register with said holes formed in the stator disks, so that the proportioning vessel occupying the first position has its inlet communicating with the tube connected to the needle introduced into the donor's blood system. The outlet of this proportioning vessel communicates with the air cushion in the vessel with the medicamental liquid. The proportioning vessel occupying the second position has its outlet communicating with the tube connected to the needle introduced into the recipient's blood system. The proportioning vessel occupying the third position has its inlet communicating with the vessel with the medicamental liquid. The outlet of this vessel and the inlet of the proportioning vessel occupying the second position communicate one with the other with the aid of a two-way cock which serves either to connect the foregoing vessels or else to connect the vessel with the medicamental liquid and the proportioning occupying the second position. The proportioning vessel occupying the fourth position has its inlet communicating with the atmosphere and its outlet with the vessel for the spent medicamental liquid.
