[A simple safe system for intra-arterial infusion by pressure-constant cuff compression of the infusion bag with the help of a reducing valve].

We describe a simple and cheap system of intraarterial infusion. It consists exclusively of single parts which are available on the market. A source of pressure is connected with a modified pressure-reduction valve which produces a constant pressure in an attached pressure cuff, respectively in an enclosed infusion-bag, so that a constant flow rate of the infusion is maintained. First clinical experiences with more than hundred angiological patients have shown that this new system has many advantages. In our routine work we had neither functional disturbances nor other complications.
