Suppository introducer
Abstract
Abstract AN INTRODUCER FOR SUPPOSITORIES AND FLOWABLE, EXTRUDABLE MATERIAL. THE INTRODUCER, WHICH IS PREFERABLY MADE OF PLASTIC MATERIAL, HAS A TUBULAR BODY WITH A FORWARD NECKED-DOWN INSERTING SECTION AND A REAR, PRESSURE-GENERATING SECTION IN THE FORM OF A CYLINDER WITHIN WHICH THERE RECIPROCATES A PRESSUREGENERATING PISTON. THE FORWARD END OF THE PISTON IS EXTENDED INTO A FORWARD PORTION HAVING A SMALLER EFFECTIVE DIAMETER, SUCH FORWARD SECTION FITTING WITHIN THE NECKED-DOWN INSERTING SECTION OF THE BODY. THE SUPPOSITORY OR OTHER MEDICAMENT IS PLACED IN THE CAVITY OF THE INSERTING SECTION OF THE TUBULAR BODY, AND AFTER INTRODUCTION OF THE INSERTING SECTION, SUCH MATERIAL IS FORCED OUTWARDLY BY THE PISTON. THE INTRODUCER OF THE INVENTION FACILITATES MANIPULATION WITH SUPPOSITORY PREPARATIONS, AND GREATLY IMPROVES THE HYGIENIC CONDITIONS DURING THE INTRODUCTION OF THE MATERIAL. D R A W I N G
