Abstract
An inhaler for powdered medicaments contained in a capsule which is inserted when needed into an elongated recess by rotatably moving two component portions out of register, perforated by means of biasedly attached piercing devices, and emptied by spinning within a cylindrical spinning chamber when air is drawn through tangentially disposed intake passages, the component portions being held in register by a latching device.
Claims18
An inhaler for powdered medicaments comprising:
- A. an elongated mouth-piece comprising a coaxially disposed inhalation passage;
- B. a body portion comprising:
- 1. a chamber which is adapted to receive a capsule containing said medicaments and which is open communication with said inhalation passage, and
- 2. an air intake passage which is tangentially disposed to said chamber;
- C. a pivot means, for pivotably connecting said mouth-piece and said body portion, comprising:
- 1. a hole within said body portion which is eccentrically disposed with respect to said chamber, and
- 2. a pivot pin which:
- a. fits rotatably within said hole so that said pin and said hole are aligned when said pin and said hole are in register,
- b. has a pivot-pin axis which is parallel to the axis of said mouth-piece, and
- c. is attached to and eccentrically disposed on one side of said mouth-piece to allow disengagement or locking by a simple rotation about said pivot-pin axis of said body portion with respect to said mouth-piece;
- D. a latching means for releasably securing said mouth-piece and said body portion when pivoted into register;
- and
- E. a capsule-piercing means on said body portion for selectively perforating said capsule, whereby said medicaments are released when air is drawn into said air intake passage and swirled about within said chamber.
10 more elements
An inhaler for administering powdered medicaments, comprising:
- A. a mouth-piece, comprising:
- 1. an ellipsoidal tuburlar portion, having a major axis in cross section, with a coaxially disposed inhalation passage therein,
- 2. an enlarged basal end which is attached to said tubular portion,
- 3. a pivot pin, having two ends, which:
- a. is rigidly attached at one of said two ends to said basal end and eccentrically disposed thereon on one side of said tubular portion,
- b. has a pivot-pin axis which is disposed in parallel to the axis of said tubular portion, and
- c. has a rigidly attached lateral projection which is diposed at the other of said two ends,
- 4an L-shaped projection which:
- a. is rigidly attached at one end to said basal end along one side thereof, and
- b. has on the other end thereof a rigidly attached latching lug which projects laterally but obliquely toward said major axis;
- and
- 5. a grating attached to said tubular portion and across said inhalation passage;
- B. a body portion, comprising:
- 1. an upper face which engages said basal end when said moutht-piece and said body portion are assembled,
- 2. a circular recess in said upper face, having tangentially disposed narrow recesses in communication therewith,
- 3. an elongated recess, disposed in said circular recess, which is adapted for receiving a capsule containing said powdered medicaments,
- 4. a hole which:
- a. is disposed eccentrically to said axis of said tubular portion,
- b. has an elongated lateral enlargement in the perimeter thereof that accomodates said lateral projection when said mouth-piece and said tubular portion are revolved to and past a loading position which exposes said chamber,
- c. extends from said upper face into said body portion for a distance equalling the distance along said pivot pin from said basal end face to said lateral projection;
- and
- d. terminates in an enlarged annular section which accommodates said lateral projection as it revolves around said pivot-pin axis while said mouth-piece and said body portion relatively revolve about said pivot-pin axis;
- 5. an L-shaped recess which:
- a. is disposed along one side of said body portion and is laterally open,
- b. is obliquely disposed to said elongated recess, and
- c. has a laterally projecting latching slot into which said latching lug revolvingly fits when said body portion and said mouth-piece are mutually revolved from said loading position to an operating position in which said circular recess is aligned with said tubular portion;
- and
- C. a selectively operable capsule-piercing means for perforating said capsule, whereby said capsule is stored in sealed condition while said inhaler is in said operating position and said medicaments are released after said capsule is pierced and air is drawn into said narrow recesses and swirled about within said chamber.
25 more elements
In an inhaler for administering powdered medicaments from a selectively pierced capsule, said inhaler having a tubular portion with a coaxially disposed inhalation passage therein and a body portion with an elongated recess for depositing said capsule therein, the improvement comprising:
- A pivot means for mutually revolving said tubular portion and said body portion from a closed operating position, in which said elongated recess is aligned with said passage and protectively covered by said tubular portion, to an open loading position, in which said elongated recess is exposed for said depositing said capsule, and furhter from said open loading position to a separating position, in which said tubular portion and said body portion are axially movable apart;
- B. a retaining means for maintaining said body portion and said tubular portion in revolvable relationship while mutually revolving from said opening position to said separating position;
- C. a joining-and-separating means, attached to said pivot means, for permitting said tubular portion and said body portion to be axially moved apart in endwise sliding relationship while said inhaler is in said separating position;
- D. a latch means for revolvingly engaging said body portion and said tubular portion in said operating position;
- and
- E. an air inlet means, comprising narrow recesses in said body portion, for admitting air into said inhaler in said operating position and for permitting visual inspection and cleaning of said narrow recesses when said inhaler is in said loading position.
3 more elements
In an inhaler for powered medicaments contained in a capsule, the improvement comprising a means for charging said inhaler with said capsule while maintaining said inhaler in connected relationship, comprising:
- A. an elongated mouth-piece, comprising on one end an air outlet and on the other end a pivotal securing means,an eccentrically mounted pivot pin, a latch, an air-pervious capsule-retaining means, and an air passage connecting said air outlet and said air-pervious capsule-retaining means;
- and
- B. a base, comprising an eccentrically mounted pivot-pin receiving means, a latch keeper, an air inlet, a capsule chamber of a size to loosely hold said capsule, and a radially extending piercing means for said capsule, whereby operation of said inhaler enables said capsule to be charged into said capsule chamber when said mouth-piece and said base are pivotably separated and enables air to be drawn through said air inlet into said capsule chamber and through said air passage to said air outlet when said mouth-piece and said base are pivotably aligned.
