Description:

This invention relates generally to inflatable surgical packs and, more particularly, to nasal packs.

This application is a continuation-in-part of my prior application entitled Nasal pack, Serial No. 250,513, filed Jan. 12, 1939.

It is an object of the present invention to provide a new and improved inflatable nasal pack so constructed as to permit a patient to breathe through the nose and to provide a pack of this character which can be easily and quickly positioned in the nasal cavity or cavities of a patient.

Another object of the invention is to provide a novel inflatable nasal pack and breathing tube which are insertable in or removable as a unitary structure from the nasal cavity of a patient.

Another object of the invention is to provide an inflatable nasal pack and a breathing tube associated therewith in a manner such that the breathing tube will not engage or contact the inner wall surfaces of a nasal cavity.

Other objects of the invention will become apparent from the following detailed description taken together with the accompanying drawing in which: Figure 1 is a diagrammatical view of a human head showing one of the nasal packs in position in the nasal cavity; Fig. 2 is a perspective view of the nasal pack; Fig. 3 is a top plan view of the pack; -Fig. 4 is a side elevational view of the pack; Fig. 5 is an enlarged longitudinal sectional view of the pack, taken substantially on the line 5-5 of Fig. 3; Fig. 6 is a fragmentary end view of one of the inflatable members, looking from left to right of Fig. 5; and Fig. 7 is a perspective view of an instrument for positioning the inflatable members in the nasal cavities of a patient. Referring to the drawing by characters of reference, the nasal pack shown comprises, in general, a pair of laterally positioned, elongated inflatable members 10 and a support or holder 11 therefor. The inflatable members 10 are alike and are preferably made of a good, thin "latex" rubber, each of the inflatable members 10 being formed with an upwardly extended portion 12, extending longitudinally thereof to provide inflatable members which in shape conform generally to the shape of nasal cavities. The support or holder 1 includes a front wall 13 from which extend spaced wings 14 which are shaped to fit over a patient's nose to aid in holding the pack in place. Preferably, the holder II is molded of a light weight plastic material.

The inflatable members 10 are each provided at one end thereof with an external neck portion 15, which neck portions fit respectively and tightly over a pair of open ended metallic sleeves 16.

At their opposite ends, the inflatable members 10 are each provided with an inturned tubular or neck portion 17 which fit tightly and respectively over a pair of open ended metallic sleeves 18.

The neck portions 15 and 17 may be stretched over their respective sleeves 16 and 18 and be held thereto by the contractual forces of the elastic neck portions, but to insure that the inflatable members 10 will not leak air, elastic bands 20 and 21 are respectively and tightly wrapped around the neck portions 15 and 17 and are sealed thereto. In each of the inflatable members 10 an open ended, flexible breathing tube 22 is provided which extends longitudinally therein and connects the sleeves 16 and 18 thus providing an air passage open at both ends to atmosphere but closed from the interior of the inflatable members 10. The breathing tube 22 of each inflatable member 10 has its opposite end portions respectively positioned and retained in the sleeves 16 and 18, and these breathing tubes 22 may be made of rubber or other suitably flexible material. In order to prevent complete collapse of the breathing tubes 22 by the pressure in the inflatable members 10, each of the breathing tubes is provided therein with a stiffening wire 23 which is coiled, as shown, longitudinally of the tube.

A pair of spaced bores 24 having counterbores are provided in and extend through the holder front wall 13 for respectively receiving external end portions 25 of the inflatable members' sleeves 16, the sleeves 16 fitting sufficiently tightly into the counterbores to hold the inflatable members solely by friction to the holder 11. Hollow pins or cannulas 26 respectively connect the interiors of the inflatable members 10 to an air chamber 27 which is provided in an enlarged portion or bottom wall 28 of the holder 11. The pins 26 extend through the neck portion 15 of the inflatable members and through the elastic sealing bands 20 which fit tightly around the pins 26 to prevent leakage of air from the inflatable members 10. The pins 26 are preferably bent substantially at right angles and extend downwardly from the inflatable members 10 into vertical bores 30 provided in the holder lower wall 28, the bores 30 leading downwardly into the air chamber 27. Respectively surrounding the pins 26, washers 31, positioned in recesses in the upper surface of the holder lower wall 28, are provided and have expansible apertures to receive the pins to prevent leakage of air from the chamber 21 along the pins. It will be seen that the inflatable members 10 and their breathing tubes 22 may be quickly and easily detached from their holder or valve body 11 as units for replacement when desired.

After the inflatable members 10 have been positioned in the nasal cavities of a patient, air is introduced into the inflatable members 10 through an air check valve which includes a-. stem portion 32 which extends into the air chami- ber 27. An inner enlarged end portion S3. df: -I the stem 32 is externally threaded to screwthread into a bore in the holder bottom wall 28 and in its outer end, the stem 32 is provided with a head 34 which abuts the outer surface of the. holder front wall 13. Opening through the head 34, an air passage or bore 35 extends longitudinally and centrally through the stem 32, terminating intermediate the ends of the stem where a transverse bore 36 leads out of the side of the stem into the air chamber 2 . A valve member 36' controls the outlet or port of the bore 36 and is in the form of a resilient open ended sleeve which may be made of rubber, the sleeve 36' surrounding the stem 32 and normally closing the port of the bore 36. Surrounding the sleeve valve 36' there is a compressible gasket 37 which seats in a counterbore and is held under compression by the head 34 of the stem 32 to prevent leakage of air under the head. In the head 34, the air passage 35 is flared or made 3 conical, as at 38, to receive the tapered nozzle 39 of a bulb type hand syringe 40 by means of which the members 16 can be inflated. As air is forced into the passage 35, the pressure of the air expands the rubber sleeve valve member 36' o40 permitting the air to pass under the sleeve 36' into the air chamber 27, whence the air passes .through the hollow pins 26 into the inflatable members 10, and when the bulb of the syringe is released, the rubber valve sleeve 36' closes the port of the bore 36, thus checking back flow of air. When it is desired to deflate the members 10, it is only necessary to release the compression on the gasket 37 by, unscrewing the stem 32 sufficiently, which operation is made convenient by the provision of a slot 41 in the stem head 34 to receive a suitable tool.

From the foregoing description it will be appreciated that I have provided a new and improved nasal pack having inflatable members for bringing the necessary pressure to bear against the nasal passage inner wall surfaces and having within said inflatable members breathing tubes so that a patient may breathe with comfort through the nose. It will further be appreciated g6 that by arranging the breathing tubes within, instead of without, the inflatable members it is much easier for the surgeon to position the inflatable members and breathing tubes in the nasal passages of a patient. In addition, it will be seen that the inflatable members 10 and the breathing tubes 22 are readily removable from the holder II as unitary structures, and thus may be easily and quickly replaced, when desired. In Fig. 7 there is shown a tool or instrument 42 by which the inflatable members 10 may be easily and quickly inserted into the nasal .passages of a patient. The instrument 42 com.prises. a pair of integral, laterally positioned ;prongs 4'3 having rounded portions or knobs 44 on their ends. In applying the pack, the prongs 43 are inserted in the breathing tubes and the rounded ends 44 lodge in the sleeves 18 which, as shown in Fig. 6, have flattened outer end portions 45 to prevent the rounded ends 44 from passing therethrough. The inflatable members may then be quickly and conveniently positioned in the nasal cavities of a patient after which, the instrument 42 is withdrawn from the pack.

While I, have shown two inflatable members, it will be apparent that they may be employed singly, in which event the support If will have but one bore 30 and may be made smaller.

SWhile I have shown and described my impirboved pack in detail, it will be apparent that many changes may be made without departing from the spirit and scope of the invention which is to be limited only by the appended claims.
