EMERGEKCY AlPLICakTQ/E AND METHOD -01 PRODUCING IT.

Application filed July 22,

Objects of the invention are to simplify the construction, lessen the cost of produc tion and increase the efliciency of emergency or single use-applicators.

Hereto-fore and before our invention it has been standard practice to provide glass or other receptacles containing fluid ant-isept-ic and a swab. Sometimes the practice was varied by securing the swab in operative relation externally of'the container. Such expedients are objectionable in a number of respects. For example, they are relatively expensive; employ. a greater charge of antiseptic than is necessary or convenient-to use; necessitate breakage of the container and removal of glass fragments from the swab; and they are wasteful and messy with stain ing fluids such as iodine and mercurochrome.

This invention materially departs from the old practice andits nature consists in an applicator and its method of production, the applicator embodying a saturated. swab and a cap oi shell for the same, readily separable without breakage and without spilling or waste.

The invention in its preferred form is illustrated in the accompanying drawings, wherein 1 Figure 1 is a perspective view of the improved applicator.

Fig. 2 is a perspective view of the parts in detached relation.

Fig. 3 is a sectional view of a specially treated applicator.

Fig. 4 is a modification in which the easing is enclosed in a first aid dressing.

According to our invention an applicator" consisting of a dry handle portion 501 rod or pencil form is equipped with a swab or brush 6 wetted with iodine, mercurochrome or other fluid antiseptic. A glass or other shell 7 envelops the moist end of the applicator and is cemented or otherwise secured in hermetic sealing relation with the handle portion, a sufiicient length of the latter protruding from the shell to permit the ready withdrawal of the applicator without the hazard of breakage of the shell. It will be understood that the swab carries enough i I I cators, which consists in providing a roll of fluid for the emergency but not enough to spill.

lVhile the invention may be practiced in various ways, it lends itself to the utilization of inexpensive and to some extent waste ma- 1927. Serial No. 207,713.

terials.v Forexample, it is possible to provide a unit swab and handle formed of cotton fiber or the like. the major lengthoi which is stiffened and rendered fluid tight. Any wax containing no unsaturated hydrocarbonwill accomplish this result although parafiin is not particularly desirable on account of its low boiling point. p

In the present embodiment a cotton roll 8, Fig. 3, is treated for. about two-thirds of its length to render that portion non-absorbent orfluid repellant, the tip or remaining portion being left in its natural state to constitute a swab. The material used for this purpose ishighly eflicient, yet a waste product. It is ceresin or silk gum, the residue in the boiling ofl process of silk, and a great deterrent to absorption.

The impregnation may be carried to a sufficient extent to insure a superficial coating 9 of the ceresin or othertreating material. The tip orswab 10 is then dipped in iodine, mercurochrome or other antiseptic solution, whereupon it is telescoped within the shell or casing and hermetically sealed therein by an application 11 of collodion or the like to the exposed end of the applicator and the adjoining portion of the shell or casing. Generally a paper wrapping or label will surround the shell and facilitate the operation. Sometimes the wrapping may take the form of a first aid dressing a'sat 12 in Fig. 4.

Having described our invention, we claim portion is impregnated with a stiffening and fluid repellant substance and whereofthe tip is wetted-with antiseptic, and a cylindrical shell telescoping and hermetically sealing the tip and from which the handle portion protrudes. s

2. A surgical applicator embodying a swab formed of absorbent material a portion of which is impregnated and stiffened with fluid repellent material to constitute a handle, and

a telescopic casing fitted to the swab and stopping short of the handle end in sealing relation therewith. 7 V

3. The method of making surgical applipellant substance to provide an impervious handle portion, applying fluid antiseptic to the pervious'portion, and hermetically sealthe fluid charged portion. 4. The method of making surgical appln cators, which consists in providing a roll of material normally absorbent, impregnating an end thereof with a stiffening and fluid repellant substance to provide an impervious handle portion, charging the pervious portion, introducing the charged end into ashell 1 or casing of less length than the roll, and

i carrying fluid antiseptic, and a cement bond between the shell and the remote end of said element.

6. A surgical applicator of substantially cartridge form, comprising a shell, an element shaped to fit and somewhat longer than the shell, said element formed of normally absorbent material whereof all but the tip is impre gented with a substance calculated to establish fluid repellant conditions, the tip carrying fluid antiseptic, a cement blond between the shell and the remote end of said element,.and a first aid dressing constituting a wrapper for the shell.

7. A self-contained non-spillable wet surgical applicator, comprising shell and core elements endwise movable in telescopic relation, the core being a unit structure of normally absorbent material whereof the 'main body portion is impregnated with wax and coated therewith to stiffen it and to render it fluid repellent, the remaining portion being in its natural flexible and absorbent state to constitute a swab, said swabbeing charged with fluid antiseptic, and a gelatine spread sealing; the handle portion of the corew1th relation to theshell;

In testimony whereof we ailix our signatures.
