TECHNICAL FIELD

[0001] The present disclosure is related to the field of medical devices. More particularly, the present disclosure relates to an apparatus for and a method of applying a substance to a lesion site in the mouth cavity of a person or animal.

BACKGROUND

[0002] Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of the common general knowledge.

[0003] Many suffer from the discomfort caused by mouth lesions. Often, these are treatable with topically applied medicaments in the form of creams, pastes, gels and liquids. Common examples of such lesions are mouth ulcers.

[0004] To apply the medicament requires some alacrity.

The battery cell 16 may be operatively connected by a wiring 18 to the switch 20 (may be referred as a fan switch 20) which, when pushed, connects or disconnects electric current to the motor 22.

[0060] The motor 22 is operatively connected by a drive shaft 26 to drive the fan, which is operatively mounted within a fan housing 28. The motor 22 is secured to the half piece 14A of the applicator body 14 by a retaining bracket 24.

[0061] The fan takes in air via an intake 44 passing though the half-piece 14A and expels the air under pressure in an accelerated stream through an outlet duct 30, which directs the airflow to an outlet at an end 32 of the applicator body 14. The outlet defines the socket 34 into which a ducted end 36 of applicator head assembly 12 is inserted, to provide fluid communication between the body 14 and the applicator head assembly12.

[0062] In some embodiments, the gas stream is directed via the outlet 40 and the substance is applied via the application surface 42 or the pad attached to the application surface.

[0063] Referring now to the Figure 3, a perspective view of the applicator head assembly 12 of the oral applicator 10 detached from the housing is shown. In some embodiments, the applicator head assembly 12 is in the form of a ducted elbow-like attachment that funnels air through an internal duct 38 to the outlet 40, located immediately to the rear of the applicator surface 42 or a delivery pad present on the applicator surface 42 (hereinafter, may also be referred as a surface face 42). In some embodiments, the pad may be formed using a porous sponge like material adapted to absorb.

[0064] In some embodiments, a substance may be applied to the applicator surface 42 for transferring the substance to the treatment site. Alternatively, a delivery pad including a resilient pad is attached to the applicator surface 42. In such embodiments, the substance may be applied to the delivery pad for applying to the treatment site in a recipient’s mouth cavity. The delivery pad may be a resilient pad configured to absorb. The delivery pad may include a contiguous surface. In some embodiments, the contiguous surface is rounded. The delivery pad is configured to be detached from the applicator surface. In some embodiments, the delivery pad is replaceable with another pad of a differing surface configuration.

[0065] In some embodiments, the gas stream generator includes a reservoir of gas under pressure and means for allowing the gas to escape from the reservoir in a stream. The gas may be air or any other suitable gas. In some embodiments, the reservoir stores the gas in an aerosol form.

[0066] In some embodiments, the outlet 40 (hereinafter, may also be referred as air leaving outlet 40) may be shaped and oriented to direct an emerging stream of air onto the surface in a recipient’s mouth at the site where the substance is to be or is being applied. In some embodiments, the outlet 40 is configured to direct the stream of the gas for drying the site prior to application of the substance and/or during application of the substance to the site, and/or after application of the substance to the site.

[0067] The substance may be of any composition suitable for application to a site in the mouth cavity. In an example, the substance is a medicament for treating a mouth condition. The condition may be sited on the tongue, a gum or a tooth, the palette, or a portion of the mouth lining, and so forth. Creams or gels in a semi solid form are applied to the applicator surface 42 of the head assembly 12. The applicator surface 42 may transmit creams and medications in semi solid form directly onto the receiving surface.

[0068] To dry the site prior to application during the application, and/or to dry the substance being applied, after its application or, the user, such as a doctor or the recipient, may activate the fan while holding the body and move the apparatus so that the air leaving outlet 40 is directed to the desired area and for required duration.

[0069] In a further embodiment, the applicator surface 42 may be in the form of an absorbent pad, for example a soft sponge that can be impregnated with a liquid medication. The sponge may transmit the medication to the receiving site when gently compressed against it by a dabbing action by the user of the apparatus.

[0070] In an alternative embodiment, the apparatus further comprises a light source i.e. an illuminator operable for illuminating the site to which a substance is to be applied using the applicator surface 42. The illuminator may include a light pipe leading light from a light source to a light outlet on the applicator head assembly 12. In some embodiments, the source may be a light-emitting diode (LED) located at the operative distal end of the applicator head assembly 12 and connected electrically to the power source using circuitry of known type and a connector associated with the connecting the socket 34 of the body 14 with a socket 36 of the head assembly 12. The LED may be connected for activation by means of the fan switch 20, so that fan and LED are simultaneously powered. In some embodiments, the LED may have a dedicated separate switch, allowing the user the choice of using the light and fan independently or simultaneously. The light source assists the user in observing the interior of the mouth and the site for application of the substance.

[0071] In an embodiment, the LED is housed within the body of the apparatus and is connected by a light pipe to a light outlet on the applicator head. The light outlet may be positioned on the leading end of the applicator, for example just above applicator pad. The light would be transmitted via the light pipe and through the elbow of applicator head assembly 12, to illuminate the receiving surface.

[0072] In some embodiments, the elbow shaped head assembly 12 is made of a see- through material, for example a Perspex formulation. When the elbow shaped head assembly 12 is attached to be in communication with a light source transmitting light from within the applicator body 14, the light is emitted into the mouth cavity via the elbow attachment. It is also within the scope of the invention for a portion, rather than the whole of the applicator assembly 12 to be a light conduit to the treatment site.

[0073] In an embodiment, the battery cell 16 may be re-chargeable, eliminating the need to be removed. A recharge connection point may be included at an appropriate site on the surface of the applicator body 14, for example at a bottom end of the applicator body, for connection with an external recharger. [0074] It will be appreciated that instead of polypropylene, the applicator body 14 may be manufactured or formed from a different plastics material, or any other suitable substance, include from a metal alloy or ceramic composite. The body shape may be altered in other embodiments to provide any suitably eye-catching design, provided it remains practically shaped for ease of holding by the user.

[0075] It is considered that for practical reasons, air is the gas of choice for use in drying the application site. However, it is still within the scope of this invention to provide means for expelling an alternative gas or mixtures of gases selected for the drying of the application/treatment site prior to application of the substance, or to dry the substance once applied. Thus, certain gases may be selected when a particular substance demands it, for example if the substance is required to undergo a reaction after application to the site. In some embodiments, the gas may be made available in aerosol form. The gas of choice may be supplied from a mini-canister mounted in the housing and connected to the supply conduit. A hand-activated valve is connected in line to control the supply outlet from the canister.

[0076] In alternative embodiments, the body 14 and applicator head assembly 12 are not separable, but manufactured in a single piece. This means the body 14 and applicator head assembly 12 may form a unitary structure. The interior is accessible through a removable closure.
