Combination intravenous infusion/blood sampling and medication injection apparatus is provided whereby a patient may be administered an intravenous infusion fluid and be subjected to blood sampling or medication injector procedures without the need to make or break any fluid connection in a sealed closed system in order to prevent possible contamination from entering the apparatus and causing injury to the patient. In combination, a three-way valve and a diaphragm sealed blood sampling apparatus is connected to intravenous infusion and catheter tubing and a flushing syringe having sterilized connections is provided. The patient need only be connected to the catheter needle once and by manipulation of the three-way valve in conjucntion with the flushing syringe, the tubing may be purged of the intravenous infusion fluid. A blood sampling syringe or medication containing syringe may thereafter be connected through the self-sealable diaphragm of the blood sampling apparatus to draw a blood sample or to inject medication. Any number of blood samples may be taken or medications injected without the need to further puncture the vein or artery of the patient and in such a manner that a completely sterile environment is maintained. Following use of the combination apparatus, the entire apparatus may be disposed of without the need for subsequent re-use or sterilization.
