Problems solved by technology

However, these devices have the disadvantage that a large part of the oxygen supplied is uselessly lost for the patient and dangerous for the operator in the operating room (especially if anesthetic gas is added)
The device is actually rather complex and difficult to operate

Embodiment Construction

[0053] [53] The device of the present invention consists of a sole purpose tongue pusher (repousse langue) 1 intended to be mounted on a medical gag 2 for endoscopy through a high access.

[0054] [54] When the patient is conscious, the gag 2 is first positioned at the mouth of the patient. Tongue depressor 1 is inserted into gag 2 once the patient is anesthetized and unconscious.

[0055] [55] The gag 2 is made of materials suitable for medical use. In practice, the gag 2 is obtained by molding a thermoplastic polymer based on polyethylene, other materials and similar manufacturing methods may be used.

[0056] [56] Reference Figure 1a , 1b , 1c and 1d, the gag 2 comprises a tubular element 4 which is inserted between the patient's teeth in order to prevent the mouth from closing.

[0057] [57] In a variant embodiment not shown, the gag 2 can also be of the type described in US Pat. No. 4.848.331 (NORTHWAY-MEYER).

[0058] [58] The tubular member 4 is positioned to form ...

Abstract

The present invention relates to an intraoral medical device comprising: a mouth opener (2) formed by a tubular element (4) arranged to define an access to the oral cavity of the patient, a tongue depressor (1) designed to be inserted removably into the tubular element (4) and having: - a channel (12) through which a breathable gas is injected and which opens out at the distal end of said tongue depressor, - a conduit through which surgical instruments are passed and which opens out at the distal end of said tongue depressor, the mouth opener (2) comprising an injection conduit (20) designed to be connected to a source of breathable gas and configured to inject said gas into the oral cavity of the patient when the tongue depressor (1) is not inserted in the tubular element (4) and to inject said gas into the injection channel (12) of said tongue depressor when the latter is inserted in said tubular element.

Description

technical field [0001] [01] The object of the present invention is an intraoral medical device. [0002] [02] The present invention relates to the general technical field of medical instruments and surgical instruments used when anesthesia or resuscitating patients, and in particular to the medical instruments and surgical instruments used when carrying out endoscopic surgery through high position access (voie haute) technical field. Background technique [0003] [03] When endoscopies are performed through elevated access, it is often necessary to resort to the supply of oxygen, usually by insertion into the mouth or into the nostrils or into the closest channel to the mouth or nostrils. [0004] [04] Intraoral medical devices are known consisting of gags equipped with channels capable of injecting oxygen into the oral cavity of a patient. Such devices are known, for example, from the documents US 4.495.945 (KENNETH), GB 2.173.105 (BARNES) or WO 91 / 08012 (BORODY). However...
