Filed June 1, 1950 INVENTORS. JULIUS SLOMOWI T Z MARIO DEL CONTE ATTORNEY Patented Dec. 18, 1951 1 UNITED STATE MEDICAL BANDAGE Julius Slomowitz, Newark, N. 1., and Mario Del .Conte, Brooklyn, N. Y.

ApplicationJuneL1950, Serial No. 165,522.

4 Claims.

, This invention relates generally to adhesive medical bandages. It pertains particularly to a type of adhesive bandage that serves not only as a protective covering for wounds, but also as a source of medicine. y

The invention represents an improvement over those bandages wherein the medicament is originally impregnated in a gauze pad. In the pres ent invention the medium of medication is not originally impregnated in a gauze pad, but is contained in a small blister embedded in absorbent material. When its use is desired the blister is gently pressed or squeezed causing it to burst. The contents thereupon oozes out and impregnates the absorbent gauze material. 7

There are many obvious advantages to a bandage of this kind. In the blister there is always contained a fresh supply ofmedicine. The medicament is sealed within the blister. There'is no danger of it becoming stale or drying out as would occur in those types of bandages where the medication is impregnated in the bandage for use at some later date.

The general object of this invention is a medical bandage containing a readily breakable blister in which there is contained a supply of medicament.

Another object of the invention is an adhesive medical bandage containing a ready source of medicine for topical application.

A further object of the invention is an adhesive bandage carrying a fresh supply of medicine at all times, and which is particularly suitable for use with boils, carbuncles, corns, and the like.

Another object of breakable blister serving as a source of medicine in the treatment of sores, wounds, bruises, and the like.

These, as well as othe objects and advantages of this invention, will .become apparent as this specification unfolds in greater detail, and as it is read in conjunction with the accompanying drawings wherein a preferred form of the inven tion as well as several modifications are illustrated.

Inthe drawings,

Fig. 1 is a perspective view of an adhesive .bandage embodying the invention with some of the elements in raised position to better reveal its construction;

Fig. 2 is the same as the view in Fig. 1, but with some of the elements removed to better reveal the basic structure;

Fig. 3 represents an enlarged longitudinal section through the center of Fig. 1, online 3-3 of the invention is a readily Fig. l with the raised elements shown in Fig. 1 in normal position.

Fig. 4 is an enlarged view of the blister itself;

Fig. 5 is a cross section of the blister;

Fig. 6 is a perspective view of a modified form of the invention;

Fig. 7 is a plan view invention may take;

Fig. 8 is a longitudinal cross section of Fig. 7 through the center;

Fig. 9 is a cross section longitudinally through the center of a form of the invention similar to that form contained in Fig. '7 but with an added feature contained in the blister; and

Figs. 10, 11, and 12 represent'further forms of the invention.

Referring to the drawings, particularly to Figs; 1 to 5, inclusive there is disclosed an adhesive bandage containing a blister carrying a supply of medicine. The bandage comprises a strip of adhesive cloth or tape l. The adhesive substance covers the inner or body contacting surface 2 of the strip. Adhering to the adhesive surface 2 is a substantially flat pad 3 consisting of a length of absorbent gauze material having several layers of thickness. Pad 3 is secured to the adhesive strip in such manner that the free end l of the bottom layer as well as an extended portion 5 of the top layer are in contact with the adhesive substance of strip l', as appears in Fig. 2. By securing the gauze in this manner to the adhesive cloth there is no likelihood of the free ends 4 and 5 of the pad becoming loose and causing the pad. to unravel. Also, by rolling the gauze material in a pad a series of folds or pockets are formed between the several layers of gauze. Between these folds, preferably the center'one, there is embedded a small, substantially flat blister 6 carrying a fresh supply of medicine 1.

The medicine carrier is called a blister, as that term best describes its nature. It is intended to be a container 'of a medicinal substance with a thin readily breakable skin covering 01' wall 8. Upon squeezing or the application of slight pressure, the substance within the blister is intended to break through the tender wall of the blister and impregnate the surrounding gauze material in which it is embedded.

The thin wall of the blister is intended to be of a soft tender material. The blister is fashioned preferably of polyethylene plastic material, which issoft and particularly adapted for the uses intended. The blister may, however, well be made of other materials suitable for the purposes intended. The blister is substantially flat and,

of another form that the preferably contains a medicament, such as iodine, mercurochrome, or other antiseptic suitable for application with everyday scratches, bruises and hurts. Blisters may be made up to carry other medicaments, such as, zinc oxide, petroleum jelly, sulfa compounds, and other ointments, salves, and powders.

An additional layer of gauze It may be laid longitudinally over the pad with its extended ends H secured in the adhesive substance of the tape I. This will effectively confine the blister within the pad and prevent its contents, when the blister is broken, from oozing out between the layers of the gauze pad. If desired, the several layers of the gauze pad may be secured or other medicament. The blister is also preferably made of polyethylene plastic material, or of some other material that is suitable for the use intended. Polyethylene is preferred because of its soft, non irritating nature. In this form it is to be noted that the blister is in the nature of a container having a base 19 and a circular wall 29. The circular wall encompasses a core of medicament 2 I The core is sealed in bya thin skin or wall 22. Because this form is of particular use for boils, carbuncles, and the like, the top surface 2-3 of the blister is slightly concaved. Slight prestogether by one or more stitches through the pad.

The gauze pad as well as the adhesive portions of tape I extending out on either side of the pad are covered by a readily removable material, such as crinoline. This backing material serves as a protective. coverin and. faci itates ha dl of the bandage, particularly the adhesive portions. This criholine material may be'a single strip runnin the full length or the bandag r. as h wn in Fig. Lit: may comprise, two strips 52, one for each end of the bandage. Each strip I2 is adhered to the a hesive. side of the tape i and extends a little beyond the middle of the pad, so that both strips Will overlap each other on. the pad 3. The

overlapping portions of crinoline are free and mayv be readily lifted for removal wh n h banda e is to be u ed as i l s rated in Fig. 1.

Having described theinven ion in il. its m ny advanta e now appear quite a p rent. I can'readily be seen how th se blisters m be made up to carry medical substances of various t pesparticularly those tha are r q ired f r everyday use with bruises, cuts, burns, scratches, minor operations, etc,- The blisters may contain such Inedicainents as iodine, mercurochrome, Vaseline, z nc oxide, carbolie salve, icthyol, sulfa, and others. The contents of the blister are sealed in and will remain fresh at all times until ready for use without drying out, or becoming stale or contaminated. V

The bandage is particularly adaptable for emergency use. All one need do when using the bandage is to squeeze the blister slightly to allow it to burst and its contents to ooze out into the absorbent gauze pad. The crinoline is then removed and the bandage is applied to the affected area" of the body. Where the bandage is to be applied to the fingers, pressure exerted on the tape while applying Will be sufiicient to cause the blister to burst and emit its contents.

The invention m y ta many-for s. s m f Whi h re added here bel w.

The embodiment in Fig. 61s an econom cal Icrm adaptable forready use with a. variety of medicine contained blisters. In; this form a blister l3 containing a inedicam nti adhered to the e r f the adhesive side of a strip of tape 14. A pad of absorbent gauze is positioned over the blister and adhered to the tape. This is a quickly put together form, economical to manufacture, and provides fair results. this form tapes, blisters, and pads may be made-up separately for quick and ready assembly when needed. Crinoline backing may also be added to this form as in Fig. 1.

In Fig. 7 is disclosed another form of the invention that is particularly adaptable for use with boils, carbuncles, and the like. In this form a strip of adhesive tape I! has adhered to its center a blister l8 containing a suitable boil ointment, r

sure on the circular wall will break the thin seal 22 and cause the medicament to ooze out. In this form the head of a boil where the medication is actually needed is permitted to extend into the core of medicament 2|. The circular wall and base of the blister are thickened to maintain the form of the blister and to serve as a protective support for the boil against rubbing and irritation of clothing, The bliste may be covered wi h a l yer oi gauze ut the p ly hyl ne. m t ial Of Which h bliste is c n tru e is .5 s h a so and non-irritating nature hat he g uze pad can be dispensed with. The purpose of thisforrn of the invention is primarily to keep the head of a boil lodged in the medication until it is ripe? This form is also of value when used in the treat me t f corns.

In cases f hose ells and ot e infec i us s res where it is desired that the wound be kept ope to prom te drainage, a form of the inv ntion as appears in F g- 9 ma be us d o a an ag Thi form is in all r spects similar o that o F g.- except that a small t mpon '24 t absorbent gauze is con a ned in the core of the b iste e ulfed i a suita l ointment 2 I s form when the blister is squeezed the thin covering seal 26 breaks and aus s th tampon o pr trude s i ht y with the medicament. The blister is then taped over he w nd. The ampon surround d by in ment will protrude slightly into the open wound to effect a continued opening of the wound and to promote d ainag A. blister 21, such as illustrated in Fig. 10, con, taining a suitable medicament according to the use intended may be embedded in a sterile abs sorbent auze p 28 s r t d. in ig. 10. A pad of. this nat r fin s many us s for topi a application as a dressing for minor operations, burn s res, and. o her ffli ti ns- There are other uses in which the blister shown in Fig. 4 finds use, such as a swab or tampon, In Fig. 11 there is shown a swab stick 29 with a tip of absorbent gauze material at one end. A blister 30 containing a supply of medicament is embedded in the gauze tip -3 l- Sli ht ben in Q squeezing of tip 3| will break the blister and al low its contents to core out and a into h surrounding gauze.

In Fig. 12 there is shown a tampon 32 suitable for insertion into the cavities of th body, such as the nasal passages .and'the like. Contained within the tampon is a blister 33 of medicine, which also can be broken b squeezing when its use is desired. The contents of the broken blist will ooze out into the surrounding tampon material. Having described the invention in its preferred form as well as in several other forms, it is in-. tended to claim all that may be reasonably included within the spirit and scope of the inven= tion as defined by the appended claims.
