A first object of the invention is to insure that medication filled syringe equipment can be kept sterile at all stages until use, is protected against malicious unauthorized use, can be packaged in a simpler way and can protect the medication to be in a stable form. A second object of the invention is to insure that an additional liquid such as an anesthetic, another medication in liquid form or a solubilizer can be aspirated by medication filled syringe equipment in an aseptic appropriate manner before injection. To attain these objects, the equipment of the invention comprises barrel 1, needle attaching portion 2 fitted with cap 11, plunger rod 22, and sealing device 31 as tube 32 of a heat-shrinkable film that is slipped over the area from the cap 11 through the barrel 1 to the basal head 23 of the plunger rod 22. The sealing device 31 is then caused to shrink thermally so that it will adhere closely to those members, thereby insuring that the barrel 1 filled with medication 5, plunger 21 and plunger rod 22 are isolated from ambient air. At the same time, the barrel 1 in which the medication 5 has been contained by the plunger 21 in a predetermined position in cooperation with the cap 11 is provided with marking 3 that is put within the area between the front and rear ends of the plunger 21 to indicate the limit beyond which the plunger 21 should not be withdrawn.
