Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
A device for crushing, dissolving in liquid and dispensing medication initially in tablet form, comprising: A. a dispenser including resiliently deformable, peripheral walls defining a chamber within said dispenser, an opening at one end thereof for insertion of a medicament tablet within said chamber; B. a removable cap closing said opening, and including a fitting for selectively coupling said dispenser and said chamber to a solvent source to enable communication between said chamber and said solvent source through said cap; C. said chamber having an outlet spaced from said opening, and said walls of said dispenser being of sufficient length and sufficiently resilient to enable repeated deformation of opposing portions of the walls into contact with said tablet and each other for crushing of said tablet to form a powder for dissolution within said chamber by said solvent and subsequent administration of the resulting solution to a patient during discharge of said solution from said outlet.
Claim 2
Independent Claim
156 words
A device for crushing, dissolving in liquid and dispensing medication initially in tablet form, comprising: A. a dispenser including resiliently deformable, peripheral walls defining a chamber within said dispenser, an opening at one end thereof for insertion of a medicament tablet within said chamber; B. a removable cap closing said opening, and including a fitting for selectively coupling said dispenser and said chamber to a solvent source to enable communication between said chamber and said solvent source through said cap; C. said chamber having an outlet spaced from said opening, and said walls of said dispenser being of sufficient length and sufficiently resilient to enable repeated deformation of opposing portions of the walls into contact with said tablet and each other for crushing of said tablet to form a powder for dissolution within said chamber by said solvent and subsequent administration of the resulting solution to a patient during discharge of said solution from said outlet.
Claim 3
Dependent Claim
28 words
The device as claimed in claim 1, further including a delivery tube coupled to said outlet and valve means for controlling flow of said solution through said tube.
Claim 4
Dependent Claim
26 words
The device as claimed in claim 1, in which said fitting includes a luer type adapter for coupling to a mating nozzle formed on said dispenser.
Claim 5
Dependent Claim
20 words
The device as claimed in claim 3, wherein said dispenser comprises syringe means having said nozzle coupled to said adapter.
Claim 6
Dependent Claim
21 words
The device as claimed in claim 1 in which said outlet is formed by an integral, tapered section of said walls.
Claim 7
Dependent Claim
24 words
The device as claimed in claim 1, further including crushing means for deforming said dispenser walls to effect said crushing without rupturing said walls.
Claim 8
Independent Claim
93 words
A method for crushing and dispensing medication in tablet or like solid form, comprising: A. inserting a tablet into a chamber having resiliently deformable, peripheral walls; B. repeatedly deforming said walls with sufficient pressure to contact each other and crush said tablet into a generally powdered form therebetween; C. introducing a solvent into said chamber after said tablet has been crushed to powder and dissolving said crushed tablet powder to form a solution thereof within said chamber; and D. displacing said solution from said chamber for administration of the solution to a patient.
Claim 9
Independent Claim
93 words
A method for crushing and dispensing medication in tablet or like solid form, comprising: A. inserting a tablet into a chamber having resiliently deformable, peripheral walls; B. repeatedly deforming said walls with sufficient pressure to contact each other and crush said tablet into a generally powdered form therebetween; C. introducing a solvent into said chamber after said tablet has been crushed to powder and dissolving said crushed tablet powder to form a solution thereof within said chamber; and D. displacing said solution from said chamber for administration of the solution to a patient.
