FR2779944A1 - Aural air-pressure compensation headset - Google Patents

Abstract

The headset comprises a flexible body (2) with internal tube (3) and ear outlets (6), with covering (5) rotatable on a circular head (4). A pressure/vacuum sensor (13) actuates a miniature evacuation pump (17) connected by flexible tubing (9,10) to the inner tube (3) and to the atmosphere by outlet (8). The pump is energized by a battery (18) controlled by power switch (15) illuminated to indicate functioning of the headset.

  HELMET FOR SUPPRESSING VARIATIONS IN

  PRESSURE OF THE AMBIENT OR VOLUNTARY ATMOSPHERE

EAR LEVEL

  The present invention relates to a helmet making it possible to avoid, suppress or cancel the pressure variations of the ambient or voluntary atmosphere at the level of the ears and more particularly the temporary disturbances caused to the medium or deep auditory system which can cause alterations and more or less deep lesions gradually leading to partial or total deafness and depending on the extent of the depression thus generated, the death of a person by rupture and / or cessation of a vital function. The present invention relates to a helmet provided with a device making it possible to

  remove or cancel the effects produced by pressure variations in the ear-canal or other peripheral organs of our body while preserving and favoring comfort, maintenance and safety in use.

  These pressure variations are often encountered in means of transport such

  than planes, boats, trains, but also deep-sea diving, in the maneuver of military engineers.

  Other variations in pressure can result from the person himself, variations due to the aging process or to certain diseases.

  The prior art shows that there are already systems to suppress variations

  pressure from the ambient or voluntary atmosphere at the ears. However, these current systems or devices have multiple drawbacks.

  tO The current systems or devices are not ergonomic and not easy to use for a non-initiated person or one who is not personally able to cause a vacuum to suppress pressure variations in the ears. Indeed, the start-up of the pump to create the air vacuum in order to cancel the

  pressures in the ear canal are done manually, providing no information by direct reading to the user as to the quantity of air drawn in.

  Too much vacuum in the ear canal would cancel the desired effect and risk causing irreversible damage or complications. The invention will be used so as to substantially avoid the disadvantages

mentioned above.

  The present invention and its advantages will appear more clearly in the description of the

  helmet eliminating pressure variations. The attached drawing illustrates the invention:

  Figure 1 shows the helmet and these different components that compose it.

  With reference to this drawing: The helmet (1) is formed by a body or structure (2) made of plastic or

  synthetic, the raw material of which will depend on the desired effect, namely PVC, polyethylene, polypropylene, ptfe loaded with one or more colors according to the need for user identification.

  The structure (2) will be rigid and semi-rigid at its base or flexible at the mouth for substantial support, thereby ensuring perfect sealing.

  To obtain the expected effect compared to the structure or body (2) we will give

  preference to the various processes such as molding, thermoforming, injection, extrusion.

  d 5 In order not to create distortion in the internal system of the device due to static electricity, care must be taken to add an anti-powder to the raw material.

  static for example carbon black. The structure (2) of the helmet or device will be on its smooth or rough external face if the

  helmet must be integrated into another device such as the helmet of a 40O fighter pilot.

  The helmet (1) has two conduits (2) having a hollow portion (3) all along it

  the diameter varies depending on the fluid to be conveyed as quickly as possible. The conduits (2) receive at their ends a round head (4).

  The round head of the duct (4) is provided with a smooth ergonomic anti-foam

  2 S allergic (5) perfectly fitting the ear canal to ensure a tight seal and bring the best result without hurting it. The comfort and sealing foam has in its middle part an orifice (6) allowing air or fluid to pass which is substantially the same diameter as the conduits (3). The material used to design the covering (5) of the support (4) is

preferably single use only.

  -3- The design of the cover (5) is specially adapted to ensure a perfect seal and obtain the desired effect. The central part of the helmet receives in its central internal part a vacuum pump (7)

  electric miniaturized air making the air vacuum by means of the conduits (3). The air05 thus accumulated is immediately removed by a flexible tube (8) or preformed in the factory.

  The tube or hose (8) fits and is fixed on the vacuum pump (7) and the end used for the extraction of air is held in place by an orifice / grid in the helmet. A flexible hose or tube preformed in the factory (9) connects the vacuum pump (7) on the one hand and

  the conduit (3) on the other hand which allows better accessibility for unela o intervention or replacement of parts.

  A flexible hose or tube preformed in the factory (10) is a derivation of the tube or flexible (9) and connected at the other end to the conduit in the notch (11) provided for this purpose. An electronic pressure switch / vacuum switch (13) is fixed by means of clips or lugs (12).

  d 5 The electronic pressure switch / vacuum switch calculates and detects the amount of air vacuum to be created.

  The desired amount of air space is preset at the factory during assembly, using an adjustment screw (l14). The pressure switch / vacuum switch can be integrated directly on the air vacuum pump or 40 mounted separately. The pressure switch / vacuum switch provides user protection on the amount of vacuum to be

  do so and thanks to its integrated detector / sensor to manage this automatically when a press button switch (15) is put into operation. The press button switch (15) will receive a light-emitting diode visible from the external face 4 to 5 specially provided so that users have a visual means of identifying the activation or function.

  The pressure switch / vacuum switch and the vacuum pump will be fitted with electrical connectors

with pins (16).

  The internal central part of the helmet has a cover (19) with location url 30 and retaining lugs (17) for a battery (18) ensuring the electrical source. Sufficient space has been voluntarily left to create a second accommodation of a

  thus prolonging the life of the helmet.

  FIG. 2: represents a flexible tube or flexible (20) which is connected to the pressure switch / vacuum switch (13) and to the tube or flexible (10). This invention is more particularly intended for all trades having to do

  in the face of variations in pressure of the ambient or voluntary atmosphere at the level of the ears as well as in the context of the individual.
