Definitions
- the invention relates to an anatomical intraoral breathing nozzle; it relates more particularly to an anatomical respiratory nozzle for medical use, for example for patients "suffering from respiratory insufficiency", that is to say who can no longer breathe by themselves, continuously or temporarily, whatever whatever the cause, such as patients with myopathy, tuberculosis or also for treatments with aerosols, medicated or not, contagious patients (HIV positive, etc.). It also relates to a respiratory nozzle for underwater diving.
- a flattened frustoconical device is inserted into their mouth, having on one side a first circular extra-mouthpiece intended to be connected to the source of oxygen-reinforced air, and a second intraoral mouthpiece whose outlet orifice is flattened and has a slight rim to be retained by the patient's teeth.
- this device has many drawbacks, namely in particular:
- the invention overcomes these drawbacks. It is aimed at an intraoral respiratory device, in particular for patients requiring respiratory assistance, which is easy to manufacture, economical, does not have the drawbacks listed above, and can be very easily put in place, without having to take fingerprints beforehand. or the like, regardless of the patient's condition or conformation.
- This anatomical intraoral breathing nozzle which includes two parts, namely:
- a plane inter-occlusal vestibulo-lingual tampon connecting the vestibules and the edges, arranged horizontally at the junction between the upper and lower parts, the thickness of said plane tampon being slightly greater than that of the inter-occlusal interval of the jaws in position rest ; characterized :
- the upper vestibular part disposed in the anteroposterior direction is located in front of the lower vestibular part.
- the invention consists of a respiratory mouthpiece of the type in question, on the one hand to provide a flexible orthosis with vestibules and vertical lingual edges connected by a horizontal plane pad, and the implantation of the vestibules of which takes counts the average mandibular position relative to the maxilla so as to avoid mandibular progression and thus improve comfort, and on the other hand, to provide that the flattened intra-oral outlet orifice opens into the planar tampon, so as not to not cause discomfort in the tongue.
- a standard device is produced capable of taking into account the specific morphology of each patient, and which can therefore be used immediately and effectively on any type of patient requiring respiratory assistance, whatever the cause.
- the flattened intra-oral outlet opens in the front part or in the lateral or even posterior parts of the vestibulo-lingual tampon;
- the distance between the two upper and lower vestibular parts is of the order of two to four millimeters, advantageously close to three millimeters;
- the thickness of the vertical vestibules decreases from the base of connection to the plan buffer to their upper end; in a practical embodiment, the thickness of the vertical vestibules is approximately two millimeters at the base and one millimeter at the free end;
- the free contour of the upper vestibule follows the contour of the flanges and brakes of the upper jaw; in this way, it is easy with a pair of scissors, to modify this contour in the case of shallow vestibules or hypertrophic brakes;
- the thickness of the pads varies from three to four millimeters, and the width of the plane of the vestibulo-lingual portion is between ten and fifteen millimeters depending on the model, so as to be slightly greater than the thickness of the teeth; in this way, one can easily produce several models, one in which the pads have a width of about ten millimeters, another with an average width of twelve millimeters and another with a width greater than fifteen millimeters;
- the lingual edges have a slightly decreasing thickness from the junction portion, for example from 2 to 1.5 mm;
- the vestibules and ledges stop substantially at the level of the premolar seconds;
- the first extra-oral part forms an angle of 15 to 30 °, preferably in the vicinity of 20 ° relative to the occlusion plane; this inclination has the advantage of avoiding that the pipe connecting to the source of gas, of air for example, to the extra-mouthpiece points vertically upwards when the patient is lying down; thus, this piping is less vulnerable;
- the orthosis is made of a flexible, thermoformable, biocompatible thermoplastic material, in particular at the temperature of the human body at the level of the mouth, so that this intraoral orthosis self-adapts quickly and gradually to the actual oral volume of the patient, or even quickly by immersion in hot water (45 ° C-50 ° C); polyvinyl chloride (PVC), for example, highly plasticized, but not loaded, is used to obtain great flexibility or any other material having the same physical characteristics.
- PVC polyvinyl chloride
- Figure 1 is a summary perspective view viewed three quarters before a respiratory nozzle according to the invention.
- FIG. 2 is a top view of this nozzle mounted in horizontal longitudinal section in FIG. 3.
- Figure 4 is a detailed view of the connection of the first extra oral part on the second part.
- FIG. 5 is a summary perspective view three-quarter rear of another embodiment of the invention, shown in rear view in FIG. 6. Way of realizing the invention
- the anatomical intra-oral respiratory nozzle according to the invention essentially comprises two parts joined together, for example molded or heat-sealed, namely respectively a first part designated by the general reference (1) and a second part by the general reference (10). It goes without saying that these two main parts can themselves consist of several secondary parts.
- the first extra-oral part (1) also known which, corresponding to the prior art, comprises a first cylindrical end-piece (2) extra-oral, intended to be connected to the gas source, for example d air enriched in oxygen, then a body (3) in the form of a flattened pyramid trunk connected to the end piece (2) by a frustoconical portion (4).
- This body (3) ends with a second intra-mouthpiece (5) whose outlet orifice (6) is flattened, for example has a rectangular section of twenty millimeters by two millimeters.
- the first part of the end piece (1) is associated with a second part (10) forming a flexible orthosis, for example made of highly plasticized PVC.
- This second part (10) firstly comprises two vertical vestibules, respectively upper (11) and lower (12), the shape of which matches the anatomical shape of the vestibules.
- the base (13,14) connecting these vestibules (11,12) to the intra-oral outlet (5,6) has a thickness close to two millimeters, while the free end (15, 16) has a thickness close to one millimeter.
- the second part (10) also comprises, arranged horizontally at the junction of the upper (11) and lower (12) parts, a buffer vestibulo-lingual plane designated by the reference (20) in the form of a smooth horizontal sidewalk or even striated inter-occlusal connecting the vestibules (11,12) to the two lingual edges (25,26) essentially vertical, respectively upper (25) and lower ( 26).
- the thickness of the pads (20) horizontal planes is slightly greater than the inter-occlusal interval of the jaws in the rest position, which allows good support in the mouth without effort and without contracture muscle, teeth resting on pads (20).
- the flattened outlet orifice (6) intra-buccal (5) opens into the thickness of the vestibulo-lingual tampon (20) (see FIG. 4).
- the tip of the invention can also be used in large prognathisms by inversion and appropriate cuts
- intraocclusal pads (20) are interconnected by a slightly convex horizontal tab (30), intended to immobilize the tongue to avoid the risk of blocking the bucco-pharingeal orifice.
- the device according to the invention has many advantages compared to those marketed to date and mentioned in the preamble. We can cite :
- this device can be used successfully for all medical respiratory insufficiencies of all kinds, especially when looking for a single-use device.
- the extra-oral part (1) can be connected directly to the regulator or to the surface breathing tube, commonly called "tuba".
