Abstract
A disposable applicator includes a generally tubular applicator body having a closed proximal end and an open distal end and a frangible vial inside. The proximal end is covered by a drying swab while the distal end is covered by an applicator swab that is in open communication with the interior of the applicator body. Within the applicator body is a frangible vial containing a biomedically useful liquid composition, such as an α-cyanoacrylate adhesive, a medicament, or both. The applicator is useful for applying liquid compositions to target sites such as tissue, particularly sites of topical pathology, such as stomatitis lesions.
Claims44
A disposable applicator for dispensing and applying a material, comprising:
- an ampoule having a first closed end and a second frangibly sealed end, the ampoule having a length and a circumference and containing a predetermined quantity of a disposable material therein;
- a flexible applicator body having a hollow main applicator body portion with a sealed proximal end and a secondary applicator body portion with an open distal end, the main applicator body portion having a length and circumference sized to receive the ampoule therein, the second frangibly sealed end of the ampoule being positioned facing the secondary applicator body portion of the applicator;
- retaining means for retaining the ampoule substantially within the applicator body;
- a first swab attached to the proximal end of the main applicator body portion;
- and
- a second swab attached to and in fluid communication with the distal end of the secondary applicator body portion,
- wherein upon application of a sufficient force applied to the ampoule through the applicator body, the ampoule will controllably rupture at the second frangibly sealed end to form an open end to allow flow of the dispensable material through the open end toward the second swab.

A method of making a disposable applicator, comprising the steps of:
- providing an open-ended hollow ampoule;
- filling the ampoule with a desired amount of a dispensable material;
- sealing the open end of the ampoule to form a frangible sealed end of the ampoule that is more preferentially frangible than remaining portions of the ampoule such that rupture controllably occurs at the frangible sealed end;
- providing a hollow applicator body having a main applicator body portion with an open proximal end capable of receiving the ampoule and a secondary applicator body portion having a distal open end;
- inserting the ampoule fully into the main applicator body portion with the frangible sealed end of the ampoule facing the secondary applicator body portion;
- sealing the proximal end of the main applicator body portion;
- attaching an applicator swab to the open distal end of the secondary applicator body portion with the applicator swab in fluid communication with the open distal end of the secondary applicator body portion;
- and
- attaching a drying swab to the proximal end of the main applicator body portion.

- a flexible applicator body having a hollow main applicator body portion with a sealed proximal end and a secondary applicator body portion with an open distal end, the main applicator body portion having a length and circumference sized to receive the ampoule therein, the second frangibly sealed end of the ampoule being positioned facing the secondary applicator body portion of the applicator;
- retaining means for retaining the ampoule substantially within the applicator body;
- a first swab attached to the proximal end of the main applicator body portion;
- and
- a second swab attached to and in fluid communication with the distal end of the secondary applicator body portion,
- wherein upon application of a sufficient force applied to the ampoule through the applicator body, the ampoule will controllably rupture at the second frangibly sealed end to form an open end to allow flow through the open end toward the second swab.
