Abstract

245,057. Pohl, E. Dec. 24, 1924, [Convention date]. Pumps.-Apparatus for the transfusion of blood comprises a pump in which two flexible tubes b. c within a casing a are compressed by rollers d which are moved about a shaft i by a handle m. The tubes b, c and additional tubes b<1>, c<1> are connected to a multi-way cock p, and with the cock in the position shown, blood is pumped from the tube c<1> to the tube c while a solution such as salt is circulated from a container s through the tubes b, b<1>. When the cock is turned to the position shown in dotted lines, the salt solution is pumped from the tubes b. b<1> to the tubes c, c<1> respectively to prevent coagulation of the blood. The axles g of the rollers d are mounted in radial slots e<1> in a plate e carrying the handle, m, and arei engaged by curved slots f in a second plate h so that adjustment of the pressure of the rollers may be effected. The plate h is locked by engagement of a spring plunger o with teeth on a curved arm n.
