Stylus applicator for a rehydrated multi-constituent medication

Claim 2

An applicator for applying a multi-constituent liquid medication to a tissue area in need of treatment, said applicator comprising: a hollow, flexible body having an open distal end and a closed proximal end; an absorbent swab retained within and projecting outwardly from the distal end of said body, said absorbent swab having a hollow compartment formed therewithin; a dry medication stored within the hollow compartment of said absorbent swab; a liquid stored within the proximal end of said body; and a defeatable fluid barrier located within said body between said distal and proximal ends to block the introduction of the liquid at the proximal end of said body to the dry medication within the hollow compartment of said absorbent swab at said distal end, the proximal end of said body being responsive to a compressive force applied thereto to generate a corresponding hydraulic pressure within the said liquid to defeat the fluid blocking integrity of said barrier so that said liquid can be introduced to and mixed with said dry medication with said hollow compartment to produce a liquid multi-constituent medication, said liquid medication being absorbed by said swab for application to the tissue area in need of treatment.

Claim 3

The applicator recited in claim 1, wherein said dry medication is a dehydrated astringent disinfectant that is rehydrated when said liquid is introduced thereto so as to produce said multi-constituent medication.

Claim 4

The applicator recited in claim 2, wherein said dehydrated astringent disinfectant is a crystalline wafer.

Claim 5

The applicator recited in claim 1, wherein said absorbent swab is an elongated stylus, one end of said stylus being received inwardly of the distal end of said applicator body to absorb the liquid multi-constituent medication, and the opposite end of said stylus projecting outwardly from said distal end to contact the tissue area to be treated.

Claim 6

The applicator recited in claim 1, wherein said defeatable fluid barrier is a deformable elastomeric septum extending in lateral alignment across the applicator body to form a fluid seal between the distal and proximal ends of said body, said elastomeric septum being responsive to the hydraulic pressure generated within said liquid for causing said septum to move out of said lateral alignment across said applicator body to thereby permit fluid communication between said proximal and distal ends so that the liquid at said proximal end can be introduced to and mixed with the dry medication at said distal end.

Claim 7

The applicator recited in claim 1, further comprising an end cap removably attached to the distal end of said applicator body to cover said absorbent swab projecting outwardly therefrom.

Claim 8

An applicator for applying a multi-constituent liquid medication to a tissue area in need of treatment, said applicator comprising: a hollow, flexible body having closed distal and proximal ends; an absorbent swab retained entirely within said body at the distal end thereof; a dry medication stored within said body and communicating with said absorbent swab; a liquid stored within said body at the proximal end thereof; a defeatable fluid barrier located within said body between said distal and proximal ends to block the introduction of the liquid at the proximal end of said body to the dry medication at said distal end, the proximal end of said body being responsive to a compressive force applied thereto to generate a corresponding hydraulic pressure within said liquid to defeat the fluid blocking integrity of said barrier so that said liquid can be introduced to and mixed with said dry medication to produce a liquid multi-constituent medication, said liquid medication being absorbed by said swab; and a peripheral tearline formed in the distal end of said body surrounding said absorbent swab so that the distal end of said body can be separated from said proximal end to thereby expose said swab within said body so that said swab can be moved into contact with the tissue area in need of treatment and apply the multi-constituent medication thereto.

Claim 9

An applicator for applying a multi-constituent liquid medication to a tissue area in need of treatment, said applicator comprising: a hollow, flexible body having closed distal and proximal ends; an absorbent swab retained entirely within said body at the distal end thereof; a dry medication stored within said body and communicating with said absorbent swab; a liquid stored within said body at the proximal end thereof; a defeatable fluid barrier located within said body between said distal and proximal ends to block the introduction of the liquid at the proximal end of said body to the dry medication at said distal end, the proximal end of said body being responsive to a compressive force applied thereto to generate a corresponding hydraulic pressure within said liquid to defeat the fluid blocking integrity of said barrier so that said liquid can be introduced to and mixed with said dry medication to produce a liquid multi-constituent medication, said liquid medication being absorbed by said swab; and a peripheral tearline formed in the distal end of said body surrounding said absorbent swab so that the distal end of said body can be separated from said proximal end to thereby expose said swab within said body so that said swab can be moved into contact with the tissue area in need of treatment and apply the multi-constituent medication thereto.

Claim 10

The applicator recited in claim 7, wherein said dry medication is a dehydrated astringent disinfectant that is rehydrated when said liquid is introduced thereto to produce said multi-constituent medication.

Claim 11

The applicator recited in claim 7, wherein said defeatable fluid barrier extends in lateral alignment across the applicator body to form a fluid seal between the distal and proximal ends, said barrier provided with at least one normally closed score line and being responsive to the hydraulic pressure generated within said liquid for causing said score line to open and thereby permit fluid communication between said proximal and distal ends of said applicator body so that the liquid at said proximal end can be introduced to and mixed with the dry medication at said distal end.

Claim 12

The applicator recited in claim 7, wherein said defeatable fluid barrier extends in lateral alignment across the applicator body to form a fluid seal between the distal and proximal ends thereof, said fluid barrier being displaced through said body and moved out of said lateral alignment across said body to open said fluid seal in response to the compressive force applied to the proximal end of said body.

Claim 13

An applicator for applying a multi-constituent liquid medication to a tissue area in need of treatment, said applicator comprising: a hollow, flexible body having an open distal end and a closed proximal end; an elongated stylus absorbent swab having a first end retained within the open distal end of said body and an opposite end projecting outwardly from said distal end to contact the tissue area to be treated; a dry medication stored within the distal end of said body and communicating with said absorbent swab; a liquid stored within the proximal end of said body; a fluid barrier extending in lateral alignment across said body between said distal and proximal ends thereof to block the introduction of the liquid at the proximal end of said body to the dry medication at said distal end, the proximal end of said body being responsive to a compressive force applied thereto to generate a corresponding hydraulic pressure within the said liquid to displace said fluid barrier through said body and move said fluid barrier out of said lateral alignment across said body so that said liquid can be introduced to and mixed with said dry medication to produce a liquid multi-constituent medication, said liquid medication being absorbed by said swab for application to the tissue area in need of treatment; and an end cap removably attached to the distal end of said body to surround the opposite end of said absorbent swab projecting outwardly therefrom.

Claim 14

An applicator for applying a multi-constituent liquid medication to a tissue area in need of treatment, said applicator comprising: a hollow, flexible body having an open distal end and a closed proximal end; an elongated stylus absorbent swab having a first end retained within the open distal end of said body and an opposite end projecting outwardly from said distal end to contact the tissue area to be treated; a dry medication stored within the distal end of said body and communicating with said absorbent swab; a liquid stored within the proximal end of said body; a fluid barrier extending in lateral alignment across said body between said distal and proximal ends thereof to block the introduction of the liquid at the proximal end of said body to the dry medication at said distal end, the proximal end of said body being responsive to a compressive force applied thereto to generate a corresponding hydraulic pressure within the said liquid to displace said fluid barrier through said body and move said fluid barrier out of said lateral alignment across said body so that said liquid can be introduced to and mixed with said dry medication to produce a liquid multi-constituent medication, said liquid medication being absorbed by said swab for application to the tissue area in need of treatment; and an end cap removably attached to the distal end of said body to surround the opposite end of said absorbent swab projecting outwardly therefrom.
