For the infusion of medicaments and drugs, in particular heparin, into the partial vacuum region of an extracorporeal blood circuit an apparatus is described which replaces the previously used heparin pump and which comprises a supply container in the form of a syringe, a shutoff member, which may be a clamp, disposed in the feed conduit, a means for measuring the reduced pressure or partial vacuum in the extracorporeal circuit and a control means. Said control means is connected to the pressure measuring means and the shutoff member and constructed for periodic opening and closing of the shutoff member in dependence upon the measured partial vacuum and the desired amount of medicament. The apparatus may be used for example in the extracorporeal blood circuit of a dialysis apparatus. |
