I have myself performed it with a simple syringe purchased at the nearest chemist's shop, when a special trans- fusion apparatus failed to act satisfactorily. FIG. 204. D Y <. D Method of transfusion by Aveling's apparatus. In immediate transfusion (Fig. 204), the donor is seated close to the patient, and the veins in the arms of each having been opened, the silver canula at either end of the instrument is introduced into them (A B). The tube between the bulb and the donor is now pinched (D), so as to form a vacuum, and the bulb becomes filled with blood from the donor. The finger is now removed so as to compress the distal tube (D'), and the bulb being compressed (c), its contents are injected into the patient's vein. The bulb is calculated to hold about two drachms, so that the amount injected can be estimated by the number of times it is emptied. The risk of injecting air is pre- vented by filling the syringe with water which is injected before the blood. SCHAFER'S DIRECTIONS FOR IMMEDIATE TRAI-SFUSION.
