ABSTRACT:
The device is carried on the body of a patient under treatment and is associated with a container to contain the fluid to be administered to and by said patient and a remote needle to inject the fluid in the patient. The device comprises a one way valve system; a first flexible tube connecting the valve to said container and a second flexible tube connecting down-stream side of the valve to the needle. The one way valve system prevents the back-flow of blood from the patient or administered fluid, and the out flow of fluid back into the container. A calibrated syringe including a plunger is mounted in a syringe holder on the upstream side of the valve system. The syringe holder acts on the plunger to withdraw a predetermined portion of fluid from the container and thereafter to inject the predetermined portion to the patient.
