Abstract

1347057 Press for a blood bag LABAZ 29 July 1971 [3 Aug 1970] 35691/71 Heading B5F [Also in Division A5] A press for compressing a blood bag 50 to assist blood transfusion or separation of blood components comprises a pair of hinged flaps 10, 11 which can be urged together by a screw 28 under control means adapted to make a determined pressure threshold or level perceptible to an operator. The control means may comprise a precalibrated spring 32 which bears against a blind recess in the screw 28 and a plate 35. The latter is provided with a boss 36 or recess for engaging with a recess 37 or boss in the flap 11. Rotation of the screw 28 through a threaded bush 25 clamped on a U bridge 20 pivoted on the flap 10 is readily effected to compress the bag 50 until a member on the rod 28 engages a member on the plate 35 whereupon the increased effort required to rotate the screw 28 and the plate 35 is perceived by the operator. The members may comprise a bent finger 40 and a pin 41 or complimentary projections and depressions. The spring 32 is exchanged for another when a different pressure threshold is to be detected. Alternatively the control means may comprise an aneroid capsule (60, Fig. 4) carried on the inner face of the flap 11 and connected to a pressure gauge (61) carried on the outer face of the flap 11. The latter is formed of transparent synthetic material, e.g. acrylic and the flap 10 may be formed of metal or transparent synthetic material. The hinge 12 comprises a metal plate provided with a free edge 15 rolled to a crook shape. A stud 18 on the flap 10 passes through a bag hole to locate the bag within the press. For blood transfusion the press is positioned as shown. For separation of blood components, an apertured extension 16 of the flap 10 is bolted vertically in a slotted base (53, Fig. 3).
