Benefits of technology

The present invention provides a versatile applicator which is ideally suited for controlled application of adhesives, especially medical adhesives. As such, the present invention is particularly useful in closing and sealing wounds and protecting tissue.
Thus, advantages of the present invention include its ability to provide a versatile system which can be used to apply adhesives either as single small drops, in a thin line, in a wide line, or as a wide surface coating.

Problems solved by technology

Unfortunately, some applicators are specifically designed to supply very small amounts of adhesive with pinpoint accuracy; whereas, other applicators have been specifically designed to supply large amounts of adhesives over wide surface areas.
To date, applicators have not been developed with sufficient versatility to apply adhesives either in very small amounts with pinpoint accuracy, or over wide surface areas.

example 2

A young female presents in the emergency room with a long shallow knife wound. After cleansing the wound, the clinician assembles a sterile medical cyanoacrylate adhesive applicator that contains 1 gram of anti-microbial butyl cyanoacrylate formulation containing a soluble poloxamer based iodophor. The cyanoacrylate adhesive formulation is enclosed in a crushable glass ampoule that is itself enclosed in a flexible butyrate tube (body 20) sealed at one end and closed with a wicking pad (sponge 26) at the other. Onto this flexible tube, over the wicking pad, she attaches a short slotted nozzle (30), and over the slotted nozzle she attaches a long pointed nozzle (40). The clinician then crushes the ampoule by squeezing on the butyrate tube thereby releasing the anti-microbial adhesive solution. The clinician then closes the wound (FIG. 6) by using the pointed applicator tip to deposit small pinpoint “spot welds” of anti-mirobial adhesive at 0.5 cm intervals along the cut while she hol...

Abstract

An adhesive applicator, for applying medical adhesives, and particularly cyanoacrylates, including a body (20) comprising an internal reservoir (22) and an opening between the internal reservoir (22) and the exterior of the body (20); a sponge (26) disposed over the opening; a slotted tip nozzle (30) disposed over the sponge (26); and a small orifice tip nozzle (40) disposed over the slotted tip nozzle.(30)

Description

TECHNICAL FIELD The present invention relates to adhesive applicators in general and to applicators for medical adhesives in particular. BACKGROUND OF THE INVENTION Many different applicators for glues and adhesives have been developed. Unfortunately, some applicators are specifically designed to supply very small amounts of adhesive with pinpoint accuracy; whereas, other applicators have been specifically designed to supply large amounts of adhesives over wide surface areas. To date, applicators have not been developed with sufficient versatility to apply adhesives either in very small amounts with pinpoint accuracy, or over wide surface areas. Such applicators are specifically desirable in medical applications where the same adhesive compound may be used to close an open cut or wound, to seal the cut or wound, and then to dress the cut or wound. SUMMARY OF THE INVENTION The present invention provides a versatile applicator which is ideally suited for controlled application of ...
