Fluid pressurizable swab applicator for medicament, antiseptic or the like
Abstract
Abstract A swab-type applicator for a treatment liquid, such as a medicament or antiseptic solution, includes an elongated tubular member of relatively small diameter fabricated of a transversely flexible, preferably transparent, synthetic plastic material chemically inert to the solution, as encapsulated in said member. The latter is provided at both ends with a rupturable sealing element in the form of a thin closure disc or membrane; this confines within the applicator tube a charge of the liquid treatment medium or solution until manual squeezing pressure on the tube between the temporarily sealed ends causes the medium to rupture one or both of the sealing elements. The tube ends are completely embedded axially in cotton or equivalent applicator swabs which are saturated upon rupture of the tube end seals. Two versions of the device are disclosed, in one of which the rupturable seal elements alone confine the charge of solution in a full tube bore length between its ends, and in another of which a small separating and sealing plug is permanently seated within the wall of the tube at its mid-point. This permits a selective squeezing and end-rupturing compression of the tube at sublengths at either side of said separator element, temporarily leaving intact the rupturable sealing element for the opposite tube sub-length.
