Medication capsule, syringe used with medication capsule and method of administrating medication
First Claim
1. The combination of(a) a capsule made of material that is compatible with long term storage therein of medication and containing multiple doses of said medication, said capsule including a sealed wall portion, and(b) a syringe includinga body member that holds the capsule,a delivery chamber accessible to the medication in the capsule upon opening of said sealed wall portion upon assembly of the body member and capsule, anda manual operable plunger member extending into the delivery chamber that is displaceable therein to draw into the delivery chamber said single dose upon displacement of the plunger member in one direction and to eject said single dose from the delivery chamber upon displacement of the plunger member in the opposite direction.

Abstract
A medical syringe employs a capsule containing multiple doses of medication within a sealed storage chamber formed between concentric inner and outer walls. The inner wall forms a cavity including a delivery chamber from which a single dose of medication is ejected. The syringe includes an ejection port, an axial moveable plunger extending into the cavity and delivery chamber, and a body with a compartment that holds the capsule. With the plunger in a first position, the capsule is closed. With the plunger in a second position, the delivery chamber is filled with a single dose of medication. With the plunger in a third position, the single dose of medication is ejected from the delivery chamber though the injection port.

1. The combination of
(a) a capsule made of material that is compatible with long term storage therein of medication and containing multiple doses of said medication, said capsule including a sealed wall portion, and (b) a syringe including a body member that holds the capsule, a delivery chamber accessible to the medication in the capsule upon opening of said sealed wall portion upon assembly of the body member and capsule, and a manual operable plunger member extending into the delivery chamber that is displaceable therein to draw into the delivery chamber said single dose upon displacement of the plunger member in one direction and to eject said single dose from the delivery chamber upon displacement of the plunger member in the opposite direction.

7. The combination of
(a) a capsule made of an inert material and containing multiple doses of medication, and including a passageway therein and a sealed wall portion made of an inert, elastomeric material, and (b) a syringe including a body member that holds the capsule, a delivery chamber at least partially disposed within the passageway of the capsule and accessible to the medication in the capsule upon opening the sealed wall portion, and a manual operable plunger member extending into the delivery chamber and manually moveable within the delivery chamber to draw into the delivery chamber from the capsule said single dose upon displacement of the plunger member in a first direction and to eject said single dose from the delivery chamber upon displacement of the plunger member in a second direction.

17. A medical syringe comprising
a body member including a capsule made of an inert material and containing multiple doses of medication, said capsule including a longitudinal passageway therein having an access opening at a proximal end and a sealed wall portion made of an inert, elastomeric material at a distal end, a tubular delivery chamber at least partially disposed within the longitudinal passageway of the capsule and accessible to the medication in the capsule upon opening the sealed wall portion, and a manual operable plunger member extending through the opening in the capsule into the tubular delivery chamber and manually axially moveable within the tubular delivery chamber to draw into the delivery chamber from the capsule said single dose upon displacement of the plunger member in a first direction and to eject said single dose from the delivery chamber upon displacement of the plunger member in a second direction opposite said first direction, said plunger member having a plunger seal thereon that contacts an inside wall of the tubular delivery chamber to assist in creating at least a partial vacuum within the delivery chamber as the plunger member moves in said first direction, said medication in the capsule flowing into the delivery chamber in response to said vacuum upon displacement of the plunger member in said first direction a predetermined distance corresponding to said single dose of medication.
-
22. A medical syringe for use with a capsule containing multiple doses of medication, said syringe including
a body member including a compartment that holds a capsule inserted therein containing multiple doses of medication, said body member having an ejection port at a distal end of the syringe, a dose meter including axial displaceable control element mounted at a proximal end of the syringe to rotate, said compartment being between the distal and proximal ends, and a delivery chamber in said body member that is interactive with a capsule containing multiple doses of medication in the compartment to draw into said delivery chamber from the capsule a single dose of medication upon axial displacement of the dose meter, said dose meter being manually attachable and detachable to the body member, upon detachment of the dose meter, said compartment being exposed to allow a capsule to be inserted into or removed therefrom and, upon attachment of the dose meter, said compartment holding a capsule containing multiple doses of medication, said dose meter upon rotation setting the dosage of medication deliverable though the injection port by axial displacement of the dose meter.

27. A, syringe comprising
a body member including an ejection port at a distal end and a plunger member at a proximal end and holding a capsule containing multiple doses of medication, said capsule having a cavity therein in which is seated a delivery chamber capable of holding a single dose of medication, said plunger member having a segment extending into the cavity of the capsule and interactive with the delivery chamber, being axial moveable within the cavity between a closed position preventing medication from flowing from the capsule into the delivery chamber, a fill position where a single dose of medication from the capsule is drawn into the delivery chamber, and an ejection position where the single dose is injected from the delivery chamber through the injection port.
-
32. A medical syringe comprising
an ejection port at a distal end of the syringe, a body member including a compartment that holds a capsule including a sealed storage chamber containing multiple doses of medication and having concentric outer and inner wall members and a seal at or near a distal end of the storage chamber that upon being opened provides access to the medication in the storage chamber, said storage chamber being formed between said concentric wall members, with said inner wall member forming a cavity within the capsule accessible through an opening at a proximal end of the capsule, and a delivery chamber in said cavity having opposed proximal and distal ends, said proximal end being accessible through the opening in the cavity and said distal end being accessible to the medication in the chamber upon opening of the seal in the chamber, a plunger member at a proximal end of the syringe, said plunger member having a segment extending into the cavity of the capsule and into the delivery chamber and interactive therewith, said plunger member being axial moveable within the delivery chamber between a closed position preventing medication from flowing from the capsule into the delivery chamber, a fill position where a single dose of medication from the capsule is drawn into the delivery chamber, and an ejection position where the single dose is injected from the delivery chamber through the injection port.
