Abstract
A device, comprising a detachably connected mouthpiece and body, for powdered substances contained in a capsule which is longitudinally inserted into the cylindrical bore of a pivotably mounted carrier member for pivoting into a transversly disposed recess in the body of the device. A pair of cutting blades is fixedly attached to the body at opposite ends of the recess for severing the ends of the capsule during the pivoting movement. A bore in the mouthpiece and body coincides with the bore of the carrier member and with holes in the blades so that air can be drawn longitudinally through the severed capsule for inhalation or insuffation.
Claims24
A device for the administration of a powdered substance contained in a capsule, comprising:
- A. a generally tubular body having a transverse recess intermediate its ends;
- B. a carrier member which is pivotally mounted in said transverse recess for pivotal movement, transversely to the axis of said tubular body, out of and into said transverse recess and having a cylindrical bore co-axial with said body for holding said capsule;
- and
- C. cutting means for opening said capsule in order to release the contents cleanly and completely, comprising a pair of cutting blades, each having a circular aperture and being fixedly mounted in said recess at each end of the bore in said carrier member with the centres of the apertures coinciding with the axis of said bore, the arrangement being such that upon pivoting the carrier member containing said capsule into said recess from a position outwardly therefrom, the ends of said capsule are severed by said blades to form an opened capsule and expose the contents of said capsule to the adjacent cavities of said tubular body.
An inhalation device for the administration of a powdered substance contained in a capsule, comprising a generally tubular body having a longitudinally disposed cavity and a transverse recess intermediate its ends, a carrier member which is pivotally mounted in said transverse recess for pivotal movement out of and into the recess transversely to the axis of said tubular body and having a cylindrical bore co-axial with said body for holding the capsule, and a pair of cutting blades, each having a circular aperture and being fixedly mounted in said recess at each end thereof with the centres of the apertures coinciding with the axis of said bore, one of said blades being disposed adjacent said cavity of the tubular body at one end thereof which constitutes an air inlet and a grating being inserted in said cavity and being positioned transversely to said bore and to said cavity to cover the circular aperture in said one blade, the device further including a mouth-piece which is secured end-to-end to the other end of the tubular body, said tubular body, having a recess at said other end, and said mouth-piece, having stepped spigot portion fitted within said recess in said other end of said tubular body, defining a mixing chamber, said recess including radially extending apertures communicating with the surrounding atmosphere and a centrally disposed diffuser cone having an axial bore extending therein, whereby the powdered substance, conveyed by suction at the free end of the mouthpiece from the opened capsule through a diffuser cone in said tubular body, is further mixed with air entering through two radial, diametrically opposite apertures formed in the walls of the mixing chamber.
In a device for administration by inhalation or insufflation, including a housing having a bore means for admitting and transmitting a flow of air through a capsule filled with a powdered substance to an administrative outlet, the improvement comprising a cutting means for opening the capsule by severing the ends of the capsule disposed within said bore means and transversely displacing the severed ends of the capsule to form an open-ended tube containing said powdered substance, and thereby admitting and transmitting a flow of air through said open-ended tube for forming an air-powder mixture that is substantially free from capsule fragments and results in substantially complete emptying of said capsule in a few inhalations or insufflations.
An insufflation device for the administration of powdered substances contained in a capsule, comprising a generally tubular body having an inlet end, an outlet end, a longitudinally disposed bore connecting said ends, and a transverse recess intermediate its ends, a carrier member mounted in said recess for pivotal movement out of and into said recess transversely to the axis of said tubular body and having a cylindrical bore for holding the capsule, and a pair of cutting blades, each having a circular aperture and being fixedly mounted in said recess at each end thereof, the axis of bore in said carrier member and the centres of the apertures in said blades coinciding with the axis of said longitudinally disposed bore of said tubular body when said carrier member is positioned in said transverse recess, one of said blades being disposed adjacent the bore of the tubular body at one end thereof which constitutes an air inlet, a grating inserted in said air inlet bore and being positioned transversely to said bore to cover the circular aperture in said one blade, said body having an outlet portion attached to said outlet end, the device further including a resilient, hand-operated pump provided at said inlet end of said tubular body by means of which a mixture of the powdered substance and air can be forced out through said outlet portion.
A device for airborne administration of powdered substances contained in a capsule which has a straight portion and a pair of ends, comprising, in combination:
- A. a generally tubular body having a longitudinally disposed bore means therewithin;
- B. a carrier means for holding said capsule in parallel relationship to said bore means within a storage bore which is as long as said straight portion, whereby said pair of ends stradles said storage bore and are outside thereof;
- C. a pair of cutting means, for slicing transversely to said bore means, which are spaced longitudinally apart by a distance equal to said straight portion;
- D. a moving means for:
- 1. moving said capsule past said pair of cutting means, so that said straight portion is severed as an open-ended tube from said pair of ends, and
- 2. continuing to move said open-ended tube into alignment with said bore means, whereby said powdered substances in said open-ended tube are readily displaced therefrom and entrained by a flow of air through said bore means.
