JAMES A. MURRAY, OF NEW HAVEN, CONNECTICUT, ASSIGNOB TO SEAMLESS RUBBER COMPANY, A CORPORATION OF CONNECTICUT.

SURGICAL PAD Specification of Letters Patent. Patented Feb. 25, 1908.

Application filed March 2. 1907. $erial No. 360.288.

To all whom it may concern:

Be it known that I, JAMEs A. MURRAY, a citizen of the United States, residing at New Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Surgical Pads, of which the following is a specification.

My invention relates to certain improvements in pads for use in surgical andob stetrical ope1ations;

An important feature of the invention consists in so constructing the pad that'when not in use it will assume a perfectly flat form and may be closely folded or rolled into a compact package convenient to handle and of such size as to occupy but very small space in a bag or instrument case.

A second feature of the invention consists in continuing the inflatable tubing, which ordinarily extends around the pad, down- -ward along the sides of the apron or extension thereof, in order to stiffen the same and increase the thickness at the edge sufficiently to prevent overflpw.

third feature consists in reducing the diameter of the inflatable tubing beyond the body of the pad proper so that the weight of the apron will be sufficient to overcome the stiffness imparted to the same by the inflated edging and cause it to bend downward at a proper angle. I

A fourth feature consists in constructing the pad so that it and its integral apron extension, edged as above described, have substantially the same form on both sides and an effective depth, equal to or greater than that of the ordinary non-reversible pad and apron, thus permitting either side thereof to be used and the pad to be reversed at will, without requiring any preliminary manipulation whatever.

A pad suitable for carrying my invention into effect is illustrated in the accompanying drawings. I wish it understood, however, thatI do not limit myself to either the exact form or construction shown, as various changes may be made therein without departing from the spirit and scope of my invention.

In the drawings: Figure 1 is a plan view of the pad before it is inflated. Fig. 2 is an edge view of the same. Fig. 3 is a cross section taken on the line s 8 of Fig. 1. Fig. 4

line 8, s, of Fig. 4, and Fig.

is a plan view of the pad inflated, showing a portion broken out and turned up to present the edge. Fig. 5 is a side view of the pad inflated. Fig. 6 is a cross section on the 7 is a similar view showing the effective depth of the pad when in use.

Referring now to the drawings, 1 represents the body of the pad which may be given any shape desired, but is preferably rectangular as shown, and forming a continuation thereof, there is an apron or extension 2, the width of which is gradually reduced to permit the lower end to enter a suitable receptacle in the usual manner.

Forming an edging extending from the bottom of the apron along both sides thereof and upward around the pad, there is an inflatable tube 3. As shown, the size of the tubing is reduced at the point where the apron joins the pad proper and thus constructed, the weight of material in the apron is sufficient to bend the tubing and maintain the apron at a proper angle.

4 indicates a spring closed valve of well known construction controlling the admis sion and exhaust opening of the tubing.

The pad may be formed of a single piece of material by being first properly blanked to provide portions suitable for forming a flat tubular edging when folded over upon the body portion and secured, or if preferred, the tubing may be formed separately and secured as shown in Fig. 6 for example. In either case the relative arrangement of the body portion of the pad and the tubular edging would be such as to render the pad reversible and equally effective regardless of which side is uppermost.

Referring to Fig. 3, it will be observed that in a collapsed state, the tubing lies sub stantially in the plane of the body portion and when inflated forms a raised edge upon opposite sides thereof, which serves to yield ingly maintain the body proper elevated or above the plane of its su port and combines with it to form a reversi le receptacle such as is shown in Fig. 6. The depth of the receptacle thus formed is practically doubled in use, as the pad yields under theweight of the body of the patient and assumes the form shown in Fig. 7.

The method of use and the many important advantages of my invention will be apparent from the foregoing description. 7

Having, therefore, described my invention, I claim:

1. A surgical pad formed of a sheet of material shaped to provide a body portion and an apron forming a continuation of the body portion and adapted to extend downwardly at an angle thereto, said sheet having 1inflatflible portions extending throughout its engt 2. A surgical pad formed of a sheet of material shaped to provide a body portion and an apron forming a continuation of the body portion and adapted to extend downwardly at an angle thereto, said sheet havinginflatable portions extending throughout its length and breadth.

3. A surgical pad comprising a body portion provided with an inflatable edging and an apron havin a similar edging of smaller diameter than t at of the body portion and forming a continuation thereof.

4. A surgical pad comprising a body portion and an apron provided with an inflatable edging, the diameter of which is reduced at the point where the apron unites with the body portion of the pad.

5. A surgical pad comprising a body portion, an apron extension movable into angular relation to the body portion, and an inflatable tube arranged as an edging about the body portion and apron.

6. A surgical pad comprising a body portion, a tubular edging secured to the body portion and providing a raised support for the same when inflated, and an apron formed as a continuation of the body portion and having the tubing extending along the sides thereof.

7. A surgical pad com rising a body portion, a tube secured to the body portion in such relation as to provide a raised edge upon opposite sides thereof when inflated and an apron formed as a continuation of the and means for pneumatically stiffening the apron.

9. A surgical pad comprising a body portion downwardly therefrom and provided with inflatable portions.

10. A surgical pad comprising a body portion having an apron extension adapted to extend downwardly therefrom, the thickness of the apron being increased at the edge to form a flat tube. a

11. A surgical pad comprising a body portion, an apron forming a continuation of the body portion and adapted to extend downwardly therefrom, and a tube secured as an edging to the body ortion and apron and arranged in such re ation as to yieldingly support the body portion in an elevated position when inflated.

12. A surgical pad comprising an inflatable portion, and a non-inflatable portion relatively arranged to provide a flexible body and apron extension having a raised edge extending above and below the same.

13. A surgical pad comprising an inflatable portion and a non-inflatable portion relatively arranged to provide a flexible body and apron extension, the thickness of which at the edge is increased to the same extent upon opposite sides thereof.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
