To the method of transfusion of blood and blood-substituting fluids

The fastest removal of the patient from shock before surgery, prevention of its recurrence during and after surgery require vigorous measures. Since one of the most effective anti-shock agents is the transfusion of blood and fluids replacing it, equipment is also of no small importance, which makes it possible to simplify the technique of technical implementation of this measure. Despite the widespread use of ampoules for transfusion of blood and other fluids, they have significant drawbacks, expressed in the following: 1. It is difficult to replace an empty ampoule with a new one, as air can enter when it is disconnected from the rubber tube leading to the needle. 2. The inclusion of additional solutions into the system occurs primitively: either by puncturing the distal section of the rubber tube, or by injecting with a syringe through the upper tube of the ampoule, or, finally, by infusion through the upper narrow part of it, as well as through a specially made for this purpose, closed with a glass or rubber stopper , ampoule.
