FIELD: medicine. SUBSTANCE: safety packed syringe set 2 is used with protection housings set 8, 104 together. Sizes of the housings are selected in such a manner to place common ampoule-needle pairs 12. Protection housings of the set are connected together by fragile links 64, 66, 130, 138. Ampoule- needle pair has hollow cylinder 14 with needle unit 24 mounted at one end, and piston 16 mounted at this end. Each protection housing has case part 38, 106, rod part 44, 108 connected fragile with one end of case part, and cap 52, 110, connected with the other end of case part. Fragile link 48, 118 breaks at any motion of rod part for pulling out needle 26 for usage. Pulling-out rod part is used for driving piston into motion in cylinder. After usage, cylinder is pulled back through case part in such a manner, that needle would place in the case part completely. At this point resilient fingers 84, 132, directed radial inside, grip shoulder 76 at bushing 34 of needle unit to prevent needle unit from jumping out of the case part, and used syringe may be taken away safely. Syringe set does not need special package and handles for ampoule-needle pair. Protection housings serve as that special package, and handles. EFFECT: improved convenience; improved safety. 14 cl, 13 dwg
