ANNA O. KI J'HN, OF SAN FRANCISCO, CALIFORNIA.

ASEPTIC APPLIANCE.

Specification of Letters Patent.

Patentedsept. *7, 1920.

Application filed 'F ebruary15, 1918, Serial No. 78,388. Renewed March 9, 1920. SerialNo. 364,520..

T 0 all whom it may concern Be it known that I, ANNA O. Kenn, a citizen of the Jnited States, residing at San Francisco, in the county of ban Francisco and State of California, have inventedv new and useful Improvements in Aseptic- Appliances, of which the following is a specification. v

My invention relates to improvements in aseptic appliances which have for their object means for obtaining access to the inner portions of the human body by the passages leading thereto and at the same time avoidingthe transference of germs tosaid interior parts from the exterior of the body or to upper parts of said passages from lower parts thereof. The objects 'of' thesev improvements are to facilitate the manipulation of the appliance, andprevent tearing and unnecessary stretching thereof, and also to render the appliance more effective for the purpose intended.

In the accompanying drawing, Figure 1 is a perspective view of a bacteria shield; Fig. 2 is a similar view of said shield with a pusher tube in position; Fig. 8 is a similar View with the tube pushed through the shield; l is an enlarged perspective view of the open endof the pusher tube; and Fig. 5 is a similar view of a modified form of bacteria shield.

'lieferring to the drawing, 1 indicates a sheet of soft rubber or other suitable material of size sufficient to cover the parts of the body adjacent to the passage and having a hole therethrough. The sheet is extended around said hole and reduced in thickness to form a tube 2 of thin soft rubber or said other material of size sufficient to line the passage, and either open or closed at the other end may be desired. 3 indicates a tube of rigid, preferably transparent, material, as glass, one end of which is closed except for a narrow elongated opening 4, the other end being removably attached to a handle 5.

Before using, the apparatus is sterilized, the tube 2 is drawn through the narrow opening 1 in the end of the tube 3 and the whole a paratus is placed in asterile covering.

In use, the sheet 1' is placed in contact with the exterior partswhich it is intended to cover, and the glass pusher tube-3 is pushed inward into the passage. Thereby the tube 2 is unfolded and inverted, passing threa-us 7.

through the transverse opening t, so that what was the inner wall of the tube 2 now contactswith the wall of the passage. The pusher tube 3 is then withdrawn or not, as desired. The passage is now lined with an aseptic lining which extends on the outside over the adjacenet parts.

' T he device as above described, except that the tube 2 and sheet 1 are now made in one piece, forms the subject matter of United States Letters Patent, granted to me August In my present invention I prevent the tube 2 from stretching longitudinally, although permitting it to stretch laterally. This I do by embedding in, or securing to, the wall of the tube in a longitudinal direction of the tube non-ela I. thread or Moreover, to strengthen the joint between the tube and the sheet, I also secure the thread to, or embed it in, the sheet 1.

In the form of the invention shown in 1, the thread does not extend beyond the free end of the tube, but on arriving at the end of the tube it is bent at right angles and extends in a circumferential direction, and is then again bent at right angles and ex ends in a direction reverse to its former direction, and the other end of the thread is bent in like manner at the border of the sheet. If the thread is cemented to one side of the tube or sheet, as shown in the drawing, then, on arriving at the free end of the tube, it is bent over he edge of the tube or sheet and yroceeds in the reverse direction on the other side thereof.

In the modifica ion of the invention shown n Fig. 5, there e used individual threads 8 extending some distance beyond the free end of the tube and the free edge of the sheet.

further improvement consists in formi uig are free end of the tube 2 with a number oi slits or fissures 9 opening from said end L and extending longitudinally therein.

By prevcn the tube stretching longiare less liable to be trans L a. tion of a passage; moreover, for tlllS reason and because of the slits or fissures 9, the end of thetube is more easily pulled out through the opening 4:.

I claim 1. ii device of the character described comprising a sheet of flexible material havand having threads secured thereto length Wise of the tube.

2. A device of the character described comprising a sheet of flexible material liElV comprising a sheet of flexible material having a hole thercthrough and a rubber tube extending from the sheet "around the hole and having threads embedded therein lengthwise ofthe tube. 1

A- device of the character described comprising a sheet o't'flexible material hav- 7 ing a hole therethrough and a rubber tube extending from'the sheet around the hole and havingthreads secured thereto lengthwise of the tube and also to the sheet.

4; A device of the character described 7 comprising a sheet'ot flexible material havin its free end.

5-. A device of the character described comprising a sheet oi flGXlblG material having a hole therethrough and a rubber tube extending from the sheet around the hole and having a thread secured thereto lengthwise of the tube and also to the sheet, and iaving an end extending beyond the tube.

6. 1' 1 device of the character described ing a hole therethrough and a rubber tube extending from the sheet around the hole and having athread secured thereto lengthwise of the tube and also to the sheet, and having an end extending beyond the sheet.

7. A device of the character described comprising a sheet of flexible material having a hole therethrough and a rubber tube extending from the sheet around the hole and having a thread secured thereto lengthwise of the tube and also to the sheet and having ends extending beyond the tube and sheet. c c

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses. v
