Patent number: 4475906Abstract: New injection syringe devices are formed of a partially flexible plastic bag which is filled with the solution to be injected. On one end there is a hollow injection needle sealed in. To separate the solution from the needle and to make the injection device tight during storage, a pressure release valve or special breakable seal is used.When a certain mechanical pressure is exerted on the outer side of the plastic bag the overpressure valve opens automatically or the breakable seal ruptures. With both systems it is possible to make ready-to-use prefilled injection devices consisting of a closed flexible plastic bag with the needle on one end. Pressure on the outside of the bag by hand or a mechanical device opens the junction between the plastic bag and the needle thus permitting the liquid content to be injected.Type: GrantFiled: September 13, 1982Date of Patent: October 9, 1984Inventor: Gunter Holzner
