PAD FOR DENTAL USE.

A p cation fil s c mer-y 2.8 ,9 2. Seri 8,2

My invention relates to improvements in pads for dental use, of the form that is used intermediate the edges of a face piece or nozzle and the face of a patient as a packing in giving an anesthetic. such as nitrous oxide gas and other gases, as oxygen and vitalized air and the like, and the object of my improvement is to produce a pad that is efficient as a packing, is antiseptic and sanitary,

I is free from odor, such as with padsof rubber, is soft and yielding, so as to have a pleasant feeling to theface, and that, furthermore, is relatively inexpensive sothat the use may be confined to a single applica- 1 tion without rendering the detail of cost prohibitive. i

In the accompanying drawing Figure 1 is a side elevation of one of my improved pads for dental use in position for use as applied to the nose only, the face piece or nozzle shown being one that is adapted to administer the gas to the nose only, apart of the outline of the face being indicated by broken lines.

Figure 2 is a similar view of a pad and nozzle that are used for application to both the nose and the mouth.

Figure 3 is a plan view of the pad shown in Fig. 1.

Figure & is an edge view of the same.

Figure 5 a plan view of the blank for the same.

Figure 6 is a plan view of thepad shown in Fig. 2. Y

My improved pads are used in place of a pad of rubber that is now in common use and is made of cotton, having an exterior of woven fabric, so as to provide a body and strength to' permit of handling both in manufacture and in use, and has a filling of cotton batting.

Considering the form shown in Fig. 1, the pad 10 is positioned between the face of the patient and the edge portions 11 of the nozzle 12, said nozzle having a mouth or opening defined by said edges 11 that. is adapted to fit around the nose only, the pad 10 having an opening 13 that will admit the nose. I

The exterior faces 14 are of relatively firm texture and maybe provided bymeans of an outer layer 15 of cotton that is matted or made into a felt and intermediate said layers 15 is a filling 16 of cotton batting.

A practicable manner of making the pads 1 find t'obe to. provide a fabric that can be out into blanks and then double the blanks back upon themselves by a return bendsoas to provide twov layers. That is to say, the material thatis used for making the pads is, actually a single fabric, though of peculiar composite form, having a substantially uniform thickness, the composition of said material in cross-section comprising a mattedv or felted structure on one face and a relatively fibrous open, or loose structure on the opposite face. The two structures are. merged along their opposed faces to form. a unitary body. The openingv 13 is formed in the two. layers. Asa'refinement in detail, the individual openings in the two layers that combine to form the opening 13 may be of different size to provide effectively a tapered form for said opening, the

individual opening in the layer that contacts with the face of the patient being the larger.

Thus in the pad 10, the two layers 17 are superimposed one upon the other and are connected at one end by the return bend 18.

The other ends may be held together to a certain extent by being stuck together in spots, as the spots 19 shown in Fig. 3. Another wayof holding together the opposed and overlapping ends is to use a few stitches, as indicated by the character 22 in Fig. 6. The spots 19 and the stitches 22, as shown, are preferably located in eachcase somewhat remote from the "opening and adjacent a corner. Said layers 17 comprise the matted or felted portion 15 on the outside and a lining 21 of cotton batting.

Thus the filling 16 of cotton batting is formed by two opposed bodies 21 of this material.

The pad 10 used with the larger nozzle 12 for enclosing the nose and mouth is made in a similar way and differs from the pad 10 described merely in the detail of size.

3 The pads 10 and 10 can be treated so as to be made antiseptic and can be made so cheaply that repeated use on the score of economy is not necessary. By using a sufficient thickness a tight joint can be made, thus avoiding leakage, so that a saving by avoiding a waste of gasis effected.

In some cases the area of the pad may be appreciably increased so as to extend beyond the nozzle laterally and cover a correspondingly greater surface of the face, particularly so as to cover the eyes.

That is to say, the function of the pad would not be limited to that of a packing to prevent leakage but would be extended so as to comprise at the same time the feature of a protection to exposed parts of the face. The utility of this last named feature would be found in connection with the use of such anesthetics as chloroform and ether and any others which in their application might in some cases involve a leakage of drops in liquid form.

Such leakage, while unintentional and accidental, is unpleasant for the patient where the face is not protected in any way, as by use of the pad mentioned. A structure such as just referred to is shown in Fig. 7 in which the pad 10 is of relatively large size, the opening 13 therein corresponding to the opening 13" in Fig. 6, and adapted for the nose and month.

In the form last described, the pad may be made of a single layer of material, with a matted form for the material .at one face and the major portion soft and yielding, after the manner of cotton batting.

The preferred material in all cases is cotton. In all case under conditions of use the pad is efleotive asa single layer and a unitary piece. The packing effect results from the use of a sufficient depth of the cotton batting. T he matted or felted layer provides for maintaining the particular form or shape, whereby the pads can be provided in a ready-to-use condition.

I claim as my invention i As a new article of manufacture, a pad for use as a packing between the endeface edges of a dental nozzle and the face in the form of a rectangular structure of plain flat material, being entirely of cotton, comprising in the cross-section a relatively yielding body for the major portion of the thickness, and

said yielding body merging at one face with a relatively firm structure that serves to maintain the general shape of the pad, and said pad being provided wlth an opening for the nose.
