Description

ACCESSORY FOR AN INHALER

THIS INVENTION relates to inhalant therapy. In particular the invention relates to an accessory for an inhalant administering device. It further relates to an inhalant administering kit, to a holder for an inhalant administering device and to a method of administering an oral medicament.

Inhalant medication is regarded as the preferred manner of treating patients with asthma. To administer the medication use is made of inhalant administering devices such as pressurised aerosol inhalers or Asthma pumps. These inhalers generally comprise a canister and a holder in which the canister is received. The canister contains a medicament in a pressurised liquid form. The holder normally includes a spray nozzle and the canister is mounted in the holder such that when the canister is displaced relative to the holder the medicament is released through the spray nozzle as a spray, which is then inhaled by a user of the inhaler. The spray nozzle is surrounded by a mouthpiece. This mouthpiece is inserted between the lips of a user and the medicament is discharged into the mouth of a user

The inventor believes that this arrangement results in some of the medicament being deposited on the teeth and gums of the user which, with long term use, can result in severe dental problems.

The invention provides an accessory for an inhalant administering device having a mouthpiece which is insertable into a front part of a mouth of a user, the mouthpiece defining a discharge opening, through which an inhalant can be discharged into the mouth of the user, the accessory including: an elongated tubular body defining an inhalant flow path between an inlet opening at a proximal end of the tubular body and an outlet opening at a distal end of the tubular body; and a mounting arrangement whereby the accessory is operatively mountable on a said inhalant administering device to form an extension of the mouthpiece.

The elongated tubular body may be shaped to clear or avoid the tongue and palate of the user, and the tubular body may have a longitudinal length at least great enough for the outlet opening to be positioned and inhalant discharged therefrom in the region of the naso- ororo-pharynx of the user. In a preferred embodiment, the elongated tubular body may have a longitudinal length of between 7 to 11 cm.

The mounting arrangement may include a straight portion of the elongate tubular body, which straight portion extends longitudinally inwardly from the proximal end of the body for part of its length, the straight portion being receivable spigot/socket fashion in the mouthpiece of the inhalant administering device.

The tubular body may include a curved portion which is connected to and protrudes from the end of the straight portion remote from the proximal end of the body.

The accessory may further include retaining means. Typically the retaining means may include a peripheral outwardly directed ridge which extends at least partway around the proximal end of the elongated body, the ridge being slidably receivable together with at least part of the straight portion in the mouthpiece of the administering device.

The ends of the body may lie in angularly spaced planes. This permits the outlet opening to be directed to discharge medicament into the pharynx. Preferably the planes in which the ends of the body lie are generally perpendicular.

The invention also provides an inhalant administering kit which includes an inhalant administering device having a mouthpiece; and at least one accessory as described above having an end portion which is snuggly and removably receivable in the mouthpiece to form an extension thereof.

The kit may further include a plurality of interchangeable accessories, the dimensions of which differ ie the longitudinal length, transverse width, and/or the curvature of the accessory may differ to suit eg different users of different ages.

The invention further provides a holder for an inhalant administering device, the holder defining a body in which an orally administrable medicament container is receivable and an opening through which the medicament is released, the holder including an elongated tubular extension piece extending from around the periphery of the opening, the elongate extension piece defining a medicament flow path between the opening and a distal end of the extension piece, the extension piece having a discharge opening at the distal end, and being configured such that when inserted into the mouth of a user the distal end can be positioned at or near the naso- or oro-pharynx region of the user.

The extension piece may be shaped to clear or avoid the tongue and palate of a user, the extension piece having a longitudinal length at least great enough for the discharge opening to reach the region of the naso- or oro-pharynx of a user. Typically, the extension piece may have a longitudinal length of between 7 to 11 cm.

The invention provides still further a method of administering an oral medicament which includes the steps of providing an inhalant administering device, having an opening through which a medicament is discharged, with an elongated tubular body extending from around the opening in the administration device, the elongate tubular body terminating at a distal end having a discharge opening at the distal end; inserting the tubular body into the mouth of a user such that the discharge opening is positioned at or near the naso- or oro-pharynx region; and discharging the medicament from the discharge opening into or near the naso- or oro-pharynx region.

The invention will now be described, by way of example, with reference to the accompanying diagrammatic drawings, in which

Figure 1 shows an oblique view of an accessory for an inhalant administering device, in accordance with the invention,

Figure 2 shows a sectional side elevation view of the accessory in Figure 1 ; Figure 3 shows an oblique view of an inhalant administering device with the accessory of Figure 1 attached thereto;

Figure 4 shows an inhalant administering device without the accessory of Figure 1 in use; and Figure 5 shows the inhalant administering device of Figure 3, in use.

In Figure 3, reference numeral 10 refers generally to an inhalant administering device which in this illustration is an aerosol inhaler also known as an asthma pump. The inhaler 10 includes a holder 12 in which an aerosol canister 14 is dismountably mounted. The holder 12 defines a mouth piece 16 and a spray nozzle (not shown) which is positioned to direct a spray of medicament out of the mouthpiece 16 as described in more detail herebelow. The aerosol canister 14 contains a medicament in a pressurised liquid form. The canister 14 is mounted in the holder 12 such that an outlet of the canister 14 is in flow communication with the spray nozzle.

In use, as can be seen in Figure 4 of the drawings, the holder 12 is positioned with the mouthpiece 16 in the mouth and in particular between the lips of a user 18. By displacing the aerosol canister 14 downwardly, ie in the direction of arrow 20, relative to the holder 12, a predetermined dosage of the medicament is discharged from the canister 14 through the spray nozzle and out of the mouthpiece 16. As the medicament is discharged, the user inhales the medicament.

Inhalers of this type are very often used in treatment of asthma.

The Inventor believes that a problem with inhalers of this type is that the medicament is discharged into the front of a user's mouth and as a result a substantial portion of the medicament comes into contact with the teeth, gums, pallet and tongue of the user and hence is not available for its intended purpose, ie bronchodilation. The Inventor further believes that when used for extended periods this medicament leads to substantial dental problems.

Reference is now made to Figures 1 to 3 of the drawings in which reference numeral 30 refers generally to an accessory, in accordance with the invention, for the inhalant administering device ie for the inhaler 10.

The accessory 30 includes an elongated tubular body 32 in the form of an elongated tube. The tube 32 is generally oblong in section transverse to its length with sidewalls of the tube defining an inhalant flow path indicated by arrow 40 (Figure 2) between an inlet opening defined by a proximal end 32.1 of the tube 32 and an outlet opening defined by a distal end 32.2 of the tube 32

The accessory 30 further includes a mounting arrangement, generally indicated with reference numeral 34, for operatively mounting the accessory 30 on the inhalant administering device ie the inhaler 10.

The mounting arrangement 34 in this embodiment includes a straight portion 34 of the tube 32. The straight portion 34 extends longitudinally inwardly from the proximal end 32.1 of the tube 33 for part of its length. The remainder of the tube 36 comprises a curved portion which initially extends operatively upwardly from the straight portion 34 and then downwardly.

The straight portion 34 is receivable snugly spigot/socket fashion in the mouthpiece of the inhaler 10 so that the tube 32 effectively constitutes an extension of the inhaler mouthpiece 16.

The dimensions of the tube 32 as well as the curvature of the curved portion 36 are selected such that in use, when the accessory 30 is mounted on the inhaler 10 and inserted into the mouth of a user, it clears the tongue and permits the distal end 32.2 to be positioned in the region of the naso- or oro-pharynx of the user, as described in more detail herebelow.

Optionally, the mouthpiece extension 30 includes, at or towards the proximal end 32.1 thereof, retaining means in the form of oppositely disposed ridge formations 38 which serve to retain the straight portion 34 of the tube 32 in position in the mouthpiece 16 of the holder 12. The ridge formations 38 are slidably receivable together with the straight portion 34 in the mouthpiece 16 of the inhaler 10.

In a preferred embodiment of the invention the tube 32 has a longitudinal length, indicated with reference letter L in Figure 2, of between 7 to 11 cm, preferably 9 cm. Further, in a preferred embodiment the ends of the body lie in angularly spaced planes, preferably the ends of the body lie in perpendicular planes indicated by A and B in Figure 2.

In use, the proximal end 32.1 of the tube 32, which forms the mouthpiece extension 30, is inserted into the mouthpiece 16 of a holder 12. In order to administer medicament, a user inserts the distal end 32.2 of the body 32 into his mouth such that the distal end is positioned close to/in the region of the naso- or oro-pharynx of the user, as indicated in Figure 5 of the drawings. The aerosol canister 14 is then displaced downwardly in the direction of arrow 20 in the manner described above and the medicament discharged from the distal end 32.2 of the mouthpiece extension 30 downwardly into the pharynx and inhaled by the user.

Although the invention has been described above with reference to an accessory or mouthpiece extension 30 which is dismountably mountable on an existing holder 12, it will be appreciated that the invention extends to a holder which incorporates the mouthpiece extension ie where the tube 32 forms integrally part of the holder 12 of the inhaler 10.

The reader will also appreciate that the accessory as described can be manufactured to have different dimensions ie different longitudinal lengths, transverse widths or have different curvatures, to accommodate different users and in particular to accommodate users of different ages.

The Inventor believes that in view of the fact that the medicament is deposited closer to the region in which it is required, the dosage of medicament which must be dispensed in orderto administerthe required dosage can be reduced substantially. In this regard, the Inventor believes that a reduction of up to 60% in the dosage can be achieved. This has benefits both from a safety and a cost point of view. In addition, little or no medicament is deposited in the mouth region which, the Inventor believes, will lead to a substantial reduction in the dental problems associated with the long term use of aerosol inhalers.
