A. F. LUZZI SEMIRIGID GAUZE Filed Feb. 5, 1,937

ATTORNEY.

Patented ct. 3, 1939 STES l" @FFEQE 4 Claims.

This invention relates to dental and surgical supplies and it has particular reference to improvements in medicinal gauze.

The principal object of the invention is to provide an improved, semi-rigid gauze especially adapted for dental use inasmuch as it is of sufficiently rigid nature as to enable it to follow the contour of a root rocket without bending, and allows one of its ends to contact the bottom of the socket, without the necessity of packing it in. Particularly, the invention anticipates a method of producing, as a new article of manufacture, a semi-rigid gauze of the character briefly described.

With the foregoing objects as paramount, the invention has other objects as well as certain steps in the method of production, to become manifest as the description proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 is a fragmentary view of a lower jaw bone structure, showing a root socket with the invention inserted therein.

Figure 2 is an elevation of a strip of dental gauze before its formation in accordance with the prescribed steps on the invention.`

Figure 3 shows the step of immersing the gauze in solution preparatory to twisting into a roll.

Figure 4 illustrates the step of twisting the treated gauze into a roll.

Figure 5 is a View of the rolled or twisted gauze.

Figure 6 is a View of the further step of reducing the roll of gauze into sections.

Figure 7 is a view of a modified step in the method inasmuch as the gauze is twisted to a greater extent to produce a spiral eiiect in the body of the twisted roll,

Figure 8 is suggessive of the step of impregnating the gauze with a water soluble gum solution by spraying, rather than by immersion, and

Figure 9 illustrates an example of the manner of shaping the .gauze for immediate use withdanger of a few stran-ds of the fibers adhering to the surrounding bony structure, which will decompose and reinfect the area. The present invention improves upon this practice by insuring against the disadvantages outlined, as will become apparent presently.

In Figure l is shown a section of the lower jaw bone l, showing a socket 2, with a section of dental gauze inserted, which is constructed according to the present invention. In carrying out the method of producing the gauze roll, a strip of surgical gauze 3 is first immersed in a gum solution soluble in water 4, such as tragacanth, acacia or the like. An example of this step is suggested more or less schematically in Figure 3. In this gure is also shown a pair of blocks Qa, attached to the receptacle and about which thegauze 3 is passed, to remove excess gum solution.

The gum impregnated strip 3 is then hel-d at one end while its opposite end is rotated to form a spiral roll 5, the cross fibers a of the strip protruding in the manner shown, which, when the strip is twisted as shown in Figures 5 and 6, provide a slightly roughened surface for retaining a generous coating of petroleum base lubricant. This coating is applied subsequent to actual use of the gauze and serves to prevent adhesion of the gauze to the tissues and for the purpose of surrounding the antiseptics carried on the gauze to lessen the possible irritating effects of such antiseptics.

The example shown in Figure 4 is purely suggestive but illustrative of one form of means for imparting a twisting action to the gauze strip 3. It is obvious that this maybe accomplished in many ways. The example shows a clamp 6, mounted on a squared shaft l, passing through a squared aperture in a mounting 8 and spring retained so that when the strip 3 is shortened by twisting, the clamp 6 will yield.

The opposite end of the strip 3 is held by a clamp 9, rotatably arranged in a mounting I0 and rotated by a hand crank il to impart a twisting action to the gauze stripl 3.

After the gauze is removed from the twisting device, it is wrapped around at fiat piece of metal or wood of suitable size, such as shown in Figure 9. The ends of the gauze rolls are clamped thereto in some convenient manner to avoid slippage, and the gauze is allowed to dry in this condition. When dry, the clamps are removed and the flat coils are simply slipped off the mandrel I3 and are cut on line to form jointly, U-shaped gauge rolls, such as illustrated in Figure 1.

In Figure 7 is shown the same strip 3, designated at l2 but to form the double spiral eiect, the gauze 3 s twisted'to a greater extent in order that the spirals b will be provided to effectively retain and convey into the tooth socket, a greater quantity of petroleum base material, which, as stated, is applied at the time the gauze is used.

In Figure 8 is shown a modified example of the step of saturating the gauze strip 3 with gum solution preparatory to the twisting step. In this modication, the gum solution is sprayed onto the strip rather than being applied by immersion.

From the foregoing it will be observed that the steps are as follows, it being understood that the various steps are not necessarily in the order described:

First, the strip of gauze 3 is sprayed or immersed in the gum solution; second, the strip is spirally twisted into a roll; third, the roll is placed in a rack to dry; fourth, the roll is cut into sections of the desired length and placed in a suitable sterile container for ultimate use as described. It is preferred that when the gauze is removed from the sterile container for use, it be immersed in a suitable antiseptic solution and then treated with a generous quantity of petroleum base material or other substance having a desirable grease base. This material is conveyed bythe gauze into the socket.

Manifestly, the construction herein described and the steps by which the method of construction is carried out may be modified to some extent and it is understood that modication of both construction and steps, which fall within the meaning and scope of the appended claims is also considered Within the spirit and intent of the invention.

What is claimed is:

1. The hereindescribed method for producing semi-rigid gauze which consists in initially immersing a strip of surgical gauze in a gum composition, then in twisting the gauze into a roll, in drying the roll and finally in dividing the roll into sections of predetermined length.

2. The hereindescribed method for producing semi-rigid gauze for dental use characterized by initially impregnating a strip of surgical gauze with a solution of water soluble gum, in causing the strip to be formed into a spiral roll; in drying the roll and nally in dividing the roll into sections of predetermined lengths.

3. TheV hereindescribed method of producing dental gauze characterized by twisting into a spiral roll, a strip of gauze saturated by a gum solution to resist expansion by absorbed moisture, in drying the twisted roll, and nally in .cutting the roll into sections of predetermined lengths for use.Y

4. The hereindescribed method for producing a gauze for dental use characterized by first twisting a gum impregnated strip of surgical gauze into a roll; in drying the roll and in dividing the same into sections of predetermined length.
