DESCRIPTIVE MEMORY
Summary of the present invention relates to a sub-gingival medicament applicator (10) which is comprised of an eerosol container (12) comprising a gingival medicament filler (14) and a nitrogen propellant (16). A long tubular nozzle (26) is attached to the container (12) and has an end piece (30) extending angularly relative to the remaining portion of the tubular nozzle. The tubular nozzle 26 has a passage 24 within it. A valve (13), provided with an actuator (2Θ), is provided for controlling the valve. fluid outflow through the interior passage (24) of the tubular nozzle to allow application of the drug through the end piece (30) to the user's gums for optimal benefit.
FIELD OF THE INVENTION
The present invention relates to drug applicators and, more particularly, to an aerosol-type applicator specially adapted for application of a gingival drug to a patient.
BACKGROUND ART DESCRIPTION
Gingival medications are usually applied topically, usually with a brush or brush. Spray devices have not been satisfactory due to the lack of control for effective application to precise areas within the wearer / patient's mouth, and, on the other hand, because the patient is often subjected to dirty clothes.
The present invention overcomes the disadvantages of prior art devices by proposing a hand-held aerosol applicator which comprises an end piece extending angularly with respect to the remainder of the applicator, which is intended to facilitate access to the area to be treated without any visual obstruction.
SUMMARY OF THE INVENTION The present invention relates to a one-hand, sub-equivalent drug applicator comprising an aerosol container that is loaded with a liquid gingival drug charge and a nitrogen propellant. Attached to the container is a tubular nozzle comprising an end piece extending angularly with respect to the rest of the applicator. The tubular nozzle has a passageway therein. A valve is provided for regulating the outlet of fluid from within the container for said passage. The container is manageable with one hand and is fitted with a valve regulating actuator. The passageway extending through the end piece may be tapered and have a membrane that conforms to the shape of the end piece and its passage and outlet opening therefor. cause either vibration of the end piece, or pulsation of the outlet liquid, or both.

DETAILED DESCRIPTION OF THE INVENTION
With reference to the accompanying drawings, and initially to Fig. 1, reference numeral 10 generally designates the sub-gingival medicament applicator according to the present invention.
The applicator (10) consists of an aerosol container (12) loaded with a fluid gingival drug load (14) and a nitrogen propellant (16). The container 12 is provided with one. valve. (18) regulated by an actuator (20) for regulating the liquid output.
The container (12) is sized to be held in the palm of a medium sized user's hand and the actuator is preferably located and shaped to allow easy manipulation by the user's thumb.
The container (12) has an outlet opening (22) for the passage (24) of a tubular nozzle (26) which is connected to the container (12). The tubular nozzle may be made of a synthetic plastic material or a suitable sterilizable material and both the tubular nozzle and container 12 may be disposable and replaceable.
Alternatively, the tubular nozzle (26) may be permanently attached to the container (12).
tubular nozzle (26) and container (12) may be separated for reloading container (12) and for washing or sterilization of tubular nozzle (26).
Referring now to the construction of the tubular nozzle 26 as shown in detail in Figures 2 and 3, the tubular nozzle 26 has an end piece 30 extending angled with respect to the remaining portion of the rod (32) of the tubular nozzle (26). The end piece 30 preferably makes an obtuse angle with the stem 32 of 135 ° to 160 ° and more preferably 150 °. The through zone (23) within the end piece is preferably tapered towards its outlet opening (36). The bottleneck shape of)
The passage zone (28) may be such as to cause output fluid pulsations and / or vibrations in the end piece (3Θ).
may cause vibration application of the
Alternatively, using a membrane (38), the medicine pulses from the gingival medicine end piece (3Φ).
shown in Fig. 4 suitably for outlet fluid and / or to
Note that the tubular nozzle stem may be much stiffer than the end piece, to facilitate application to the desired medicated area.
