Application filed November 11, 1910. Serial No. 591,874.

To all whom it may concern: I

Be it known that I, JEFF D1 ROBERTSON, a citizen of the United States, residing at Paducah, in the county of McOracken and State of Kentucky, have invented a new and useful Obstetrical Pad, of which the follow.- ing is a specification.

This invention relates to obstetrical pads.

Most of the obstetrical pads now on the market are made of vulcanized rubber, and owing to this fact, it is practically impossible perfectly to sterilize them without permanent injury, as boiling-water or extreme dry heat has to be employed for the purpose, either of which soon hardens therubber and causes it to crack, and thereby renders the pads worthless, and as they are very expensive, few surgeons own more than one. As perfect sterilization cannot be secured except by the methods noted, it follows that these pads inevitably become germ laden and their use is a constant menace to human life, especially after having been employed in infected cases. Furthermore, as the cushion is an integral part of the pad, should the former become punctured or cut in such manner as to preclude repairs, the whole has to be cast aside as useless.

Itis the object of the present invention in a novel and thoroughlypractical manner to overcome the above objectionable features, and to provide a pad, which while possessing all of the advantages of a vulcanized rubber pad, will be free from any of its disadvantages, and furthermore to render it possible to produce the pad so cheaply, that a surgeon need only use one but once, thereby positively eliminating all danger of subjecting a patient to infection from germs, or septic matter.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, in the various novel details of construction of an obstetrical pad, as will be hereinafter fully described and claimed.

In the accompanying drawing forming a part of this specification, and in which like characters Ofreference indicate corresponding parts :--Figure 1 is a view in perspective of the pad, shown in inverted position. Fig.

2 is a transverse sectional view on an enlarged scale. Fig.3-is a top plan view of made substantially in the form shown in Fig. 4, or it may be a straight length of rubber tubing, or may be of any desired contour, and is provided with the usual filling nipple 6 that projects through a lateral opening in the upper side of the flap provided for the purpose.

While it will generally be preferable to employ a rubber cushion, it is to be understood that any other material suited to the purpose may be used, such as gut, and still be within the scope of the invention.

In order to cause the tube to assume the form shown in Fig. 1, that is to break without folding, bands 8 are provided at the points where the bends will occur. 7

It will be seen from the foregoing description that the cushion is absolutely protected from all danger of coming into contact with any septic matter, so that after the pad has once been used, the cushion can be removed, and if desired the pad or sheet may be sterilized or cast aside as preferred.

As a matter of precaution, and to insure the positive protection of the cushion from infection, a strip 9 of adhesive tape may be employed which will be pasted over the edge of the mouth and to the sheet or pad, and will thus hermetically seal the pocket.

I claim 2-.-

1. An obstetrical pad embodying a sheet of water proof material having one end folded upon itself and secured along its sides to the sheet and transversely from the sides inward for a portion of the width of the sheet to provide'a mouth, and an inflatable tube insertible into the pocket through the mouth.

2. An obstetrical pad embodying a sheet In testimony that I claim the foregoing of Waterproof material provided on its 1111- as my own, I have hereto affixed my signader side at one end with a pocket and having ture in the presence of two Witnesses.
