MODIFIED DISPOSABLE INJECTOR DEVICE |
摘要 |
The present invention is a modified single use hand-operated injector device consisting of a plunger, a base, a snap means for resisting plunger movement and an injection means for injecting parenteral medication through a skin surface of a patient. The improvement comprises a check valve seated in a cannula and a widened receptacle area within a high pressure barrel through which the cannula passes. When the check-valve plug expels upon increase in pressure, into the widened receptacle area the parenteral medication efficiently flows around the plug and into the subcutaneous tissue of the patient. |
