Jan.22,1946. L "2,393,326 J ANESTHETIC MASK Filed Dec. 29, 1944 Patented Jan. 22, 1946 Jack N.
Lane, United States Navy, Washington, D. 0.
Application December 29, 1944, Serial No. 570,423
(Granted under the act of March 3, 1883, as
amended April 30, 1928; 3700. G. 757) 4 Claims.
to a patient in any position, not merely when he is lying on his back, but also when he is lyin on a, side or lying face down.
A further object of this invention is to provide an anesthetic mask which makes it possible to place the patient in the best possible position for the operation to be performed and to continuing shown at l5 for the mask M in Fig. 5'. Also, the wires l5 could be made continuous instead of terminating in the plate l8, as shown.
In operation, having been anesthetized to a plane of anesthesia wherein he can tolerate an intra-tracheal tube of suitable size, the patient is placed on the operating table 24 in a, suitable position for the operation to be performed, here ously administer the ether or anesthetic in that Fig. 4 is a perspective view of the mask cage,
and
Fig. 5 is a perspective view of a slightly modified form of mask cage.
There is shown at I!) the anesthetic or ether mask of this invention used in connection with an intra-tracheal tube II which is inserted into the trachea of the patient F2. The mask In consists of a mask cage 14, entirely of metal or other suitable material, consisting of a plurality of spaced-apart wires I5 extending from a flange [6 on a tube ILthe wires l5 being joined together in a plate I8. To facilitate cleaning and to prevent corrosion, the cage M, if of metal, will preferably be provided with a non-corrosive plating such as chromium plating or other suitable material which is not affected by the ether or other anesthetic that may be used. A nipple having a knurled flange 2| is provided for connecting the cage tube I! to the intra-tracheal tube H, the intra-tracheal tube ll being of a suitable semi-flexible material such as rubber or plastic which will not react with either the anesthetic or the body liquids to which it may be exposed.
A gauze bag 22, made of layers of gauze, is tied around the cage I4, being held by cords 23 if necessary, thus completing the mask, the wires l5 being bowed, as shown, to provide a suitable cubical space within the mask l4.
Obviously, the wires [5 maybe shaped somewhat differently than shown, a modified form beshown as being face down, in connection with an operation to be performed on the back area of the patient. In such position the patients chin will be supported in a suitable supporting chin rest 25. The tube I I is inserted into the patients trachea, being taped to the face if necessary. The mask l4 having been joined to the tube H by means of the nipple 20, and with the gauze 22 in position thereon, the anesthetist administen; the ether or other anesthetic by the conventional drip method; that is, he merely drips it on to the gauze bag 22 at a suitable rate and the patients breathing will cause suction on the bag to deliver air and anesthetic vapor through the tube.
Other modifications and changes in the number and arrangement of the parts may be made by those skilled in the art without departing from the nature of this invention, within the scope of what is hereinafter claimed.
The invention herein describedsand claimed may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
- What is claimed is:
1. An anesthetic mask for administeringanesthetic to a patient in any position through an intra-tracheal tube, said mask comprising a cage adapted to be connected to the intra-tracheal tube and gauze means embracing said cage, said cage comprising a plurality of spaced-apart wire members and a tube from which said wire members extend, and nipple means for joining said cage tube to the intra-tracheal tube.
.2. An anesthetic mask for administering anesthetic to a patient in any position through an intra tracheal tube, said mask comprising a. cage adapted to be connected to the intra-tracheal tube and gauze means embracing said cage, said means comprising a gauze bag extending about said cage and tie means for securing said gauze bag on said cage tube.
3. An anesthetic mask for administering anesthetic to a patient in any position through an intra-tracheal tube, said mask comprising a. cage adapted to be connected to the intra-tracheal tube and gauze means embracing said cage, said 5 cage comprising a plurality of spaced-apart wire members and a tube from which said wire members extend, said cage tube being joined to the intra-tracheal tube.
