Drug delivery system including holder and drug container
First Claim
1. A system for delivering at least one substance in at least two doses, comprising:
- a drug container including a barrel having a rim surrounding an open end and extending to a first end, and a stopper slidably positioned within said barrel;
a holder having a distal portion with a distal end through which said first end of said container extends and an open receiving end for receiving said container and a proximal portion with the distal portion being assembled to said distal portion, with the drug container secured therein; and
a plurality of slots extending axially along at least one of said portions of the holder whereby upon activation of said system, said portions of said holder move towards one another upon the application of a minimum force and said stopper moves a preselected axial distance to expel at least a portion of said substance from said drug container, at least one detent disposed adjacent said receiving end of said distal portion and dimensioned so that said rim is securely retained in said distal portion by said detent.

Abstract
A drug delivery system for administering preset doses of a substance such as a drug, vaccine or the like is provided. The drug delivery system includes a holder and a pre-filled drug container such as a syringe which is securely retained in the holder. The drug container includes a barrel for containing the substance, a movable stopper situated within the barrel, and a blunt end having an opening through which the substance within the barrel can be expelled. The holder includes a distal portion and a proximal portion, each configured to accommodate the drug container, with the distal portion being able to be assembled to the proximal portion, which acts as a plunger rod during activation of the delivery system. A plurality of slots are provided for controlling the delivery of a substance and extend axially along at least one portion of the holder whereby upon activation of the system, the portions of the holder move towards one another upon the application of a minimum force and the stopper moves a preselected axial distance to expel at least a portion of the substance from the drug container. One application is to a nasal drug container, where approximately equal doses of the substance are desired to be administered to each nostril of the patient.

6. A system for delivering at least one substance in at least two doses, comprising:
-
a drug container including a barrel, a first end extending from said barrel, and a stopper slidably positioned within said barrel;
a holder having a distal portion including at least one pair of ribs and a proximal portion having at least one pair of slots with the drug container secured therein;
means for controlling the delivery of a substance contained in the barrel of the drug container whereby upon activation of said system, said portions of said holder move toward one another upon the application of a minimum force and said stopper moves a preselected axial distance to expel at least a portion of said substance from said drug container;
said pair of slots including a first slot and a second slot extending axially along the body of the proximal portion of the holder generally parallel to each other and dimensioned and situated to accommodate said ribs of said distal portion so that one of said ribs is insertable into each slot and able to travel along said slot upon activation of the system. - View Dependent Claims (7, 8, 9, 10)

11. A holder for a drug container, comprising;
-
a distal portion including at least one pair of ribs and a proximal portion having at least one pair of slots and configured to accommodate a drug container filled with a substance to be delivered, with the distal portion being able to be assembled to the proximal portion for controlling the delivery of the substance, whereby when said portions of said holder are moved towards one another upon the application of a minimum force, at least a portion of the substance can be expelled from said drug container, said pair of slots including a first slot and a second slot extending axially along the body of the proximal portion of the holder generally parallel to each other and dimensioned and situated to accommodate said ribs so that said ribs of said distal portion are insertable into the slots and able to travel along the slots upon activation of the system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A system for the nasal delivery of a substance, comprising:
-
a syringe including a barrel, a first end extending from said barrel, said first end including a spray nozzle having an opening for dispensing the substance from said barrel, and at least one stopper slidably positioned within said barrel;
a holder having a distal portion including at least one pair of ribs and a proximal portion having at least one pair of slots, each having a generally tubular interior configuration to accommodate said syringe, with the distal portion being able to be assembled to the proximal portion, which acts as a plunger rod during activation of the system;
means for controlling the delivery of said substance including a plurality of slots extending axially along at least one of said portions of the holder whereby upon activation of said system, said portions of said holder move towards one another upon the application of a minimum force and said stopper moves a preselected axial distance to expel at least a portion of said substance from said syringe, with said preselected axial distance corresponding to about half the distance that said stopper is capable of moving within said barrel to administer about half of said substance contained by said syringe barrel; and
said slots in said proximal portion of said holder including two corresponding sets situated on each side thereof, with each set including a first slot and a second slot extending axially along the body of the proximal portion of the holder generally parallel to each other and dimensioned and situated to accommodate said ribs so that said ribs are insertable into the slots and able to travel along the slots upon activation of the system. - View Dependent Claims (20, 21, 22, 23, 24)
