摘要： A cartridge-type syringe in which a cartridge, having liquid medicine or the like sealed therein, is inserted in a holder having a discharge needle at its distal end, and the cartridge is advanced to cause the discharge needle to pierce it, thereby injecting the liquid medicine or the like into an object, and when a piston rod of the cartridge is pushed to cause the discharge needle to pierce, the liquid medicine or the like will not be discharged in error in a large amount. In particular, there is provided a releaseable lock mechanism by which when a piston rod 15 is pushed, the piston rod 15 advances together with a tubular body 11 of a cartridge 10 without moving a piston 14 within the tubular body 11. For example, in a first embodiment, when a discharge needle 5 pierces the distal end of the tubular body 11, an engagement member 24 is pressed to be brought into intimate contact with the piston rod 15, thereby releasing the lock mechanism 21, and by pushing the piston rod 15, the piston 14 is driven to advance within the tubular body 11, thereby discharging liquid medicine or the like via the discharge needle 5.

摘要： 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.
