R. GIRAUDON Aug.27, 1957 SURGICAL DEVICE FOR PATIENTS UNDERGOING A LARYNGOTOMY Filed Oct. 1, 1956 INVENTOR R. GIRAUDON United States Patent SURGICAL DEVICE FOR PATIENTS UNDER- GOING A LARYNGOTGM Ren Giraudon, Marseille, France Application October 1, 1956, Serial No. 613,062 Claims priority, application France October 3, 1955 3 Claims. (Cl. 128-351) This invention relates to means for assisting patients undergoing the operation of laryngotomy and has particular reference to a surgical device so designed that it will enable the patient to breathe and restore his or her faculty of speech.

It is known that a laryngotomy becomes compulsory when the respiratory tracts are obstructed by a tumor; however, this operation is attended by the loss of the vocal cords so that the patient becomes aphonous for life.

The device according to this invention is of simple and aseptic construction and consists essentially of a valve connected to the cannula inserted into the trachea and of a conduit connected at one end to this valve and at the other end to the back of the throat through the intermediary of a non-return ball-valve; the first valve is normally urged resiliently away from its seat to allow the passage of air therethrough, the ball-valve being closed; the reverse occurs when the patient breathes out air from his or her lungs, thereby restoring the faculty of speech.

A typical embodiment of the device broadly set forth hereinabove will now be described more in detail with reference to the attached diagrammatic drawings forming part of this specification.

In the drawings:

Figure l is an elevational view showing the device of this invention fitted in the throat of a patient (shown in section);

Figure 2 is a front view showing the valve from patients side;

Figure 3 is a plan view from above of the device;

Figure 4 is a section taken upon the line IV-IV of Fig. 2, and

Figure 5 is another section showing the arrangement of the ball-valve provided in the conduit connecting the valve body to the back of the throat.

The operation called laryngotomy becomes compulsory when the trachea 1 is stopped up by a tumor such as 20 which prevents the normal breathing through thenose 3 or mouth 4 of the patient; this operation consists in cutting the trachea below the tumor and introducing a cannula to enable the patient to breathe again; however, this causes the patient to become aphonous.

The device according to this invention comprises avalve body 9 for example of sterilized plastic material, rigid with a curvedplastic cannula 10 adapted to be introduced into the trachea 1; thevalve member 12 is normally held away from itsseat 21 by aspring 11 maintained for example by means of anadjustable screw 22.

This valve may be formed with an integral shank and provided with retaining pins not shown and a compression spring.

When thevalve 12 is open the air may flow in the direction of the arrow F and penetrate into the patients lungs through thecannula 10.

Thevalve body 9 has secured thereon a screw-threadednozzle 14 formed with left-hand or right-hand threads and leading into the valve body; the flexible pipe 8 is connected to the lower end of this nozzle; the patients throat is perforated to permit the passage of anaseptic cannula 5 opening into the back of the mouth; thesecannulae 5 and 8 are interconnected through a non-return ball-valve 6 in which the ball 7 is normally seated to prevent any passage of air fromcannula 5 to cannula 8 and the ingress of mucosities or liquids from the mouth 4 oroesophagus 2 into the valve and trachea.

A pair oflugs 16, 17 maybe molded integrally with thevalve body 9 and formed withholes 18 for securing thereto a cord (not shown) for attaching the device on the patients neck.

Finally, adrain plug 19 may be screwed on the bottom of thevalve body 9 and a protective case provided in front of the valve with air holes (not shown).

With the apparatus in position as shown in Fig. 1, when the patient breathes out thevalve member 12 engages itsseat 21 against the resistance of thecompression spring 11; air is thus discharged through thehole 15 andnozzle 14, and then through the cannula 8 to unseat the ball 7 and enter theother cannula 5 and the back of the mouth at 4; thus, the patient may articulate and emit sounds.

When the patient stops the utterance of sounds, thespring 11 seats thevalve 12 and normal breathing conditions are restored in the direction of the arrow F, while the ball 7 closes the cannula 8.

Of course, many modifications and alterations may be brought to the typical embodiment shown and described herein, without departing from the spirit and scope of the invention as set forth in the appended claims. Thus, any suitable and known valve means may be incorporated in the device, and means other than the aforesaid cord may be used to secure the device on the patients neck.

What I claim is:

l. A surgical device intended for patients having undergone the operation of laryngotomy, which comprises essentially a valve body of light aseptic material adapted to be fitted on the patients neck and including a valve, a cannula adapted to be fitted into a passage cut through the wall of the trachea and connected to the aforesaid valve body, a return spring arranged to normally hold said valve in its open position to enable the patient to breath air into the lungs, a nozzle leading through a gaged orifice into the valve body, another cannula adapted to connect said nozzle to the back of the patients mouth through a passage cut to this end through the patients neck, and a non-return valve interposed in said other cannula and so arranged as to be closed when the patient breathes in and open when the patient breathes out as said valve is closed simultaneously.

2. A device according to claim 1, comprising means for adjusting the force of the valve spring.

3. A device according to claim 1, wherein said nonreturn valve comprises a ball-valve and a corresponding seat.
