Abstract

The subject of the invention described is an apparatus producing a flow of air loaded with water vapour, or vapour of any other appropriate liquid, which can be used in the medical treatment of inflammations of the nasal mucosa, such as rhinitis. It comprises air supply means, means for heating this air, means for vaporising water or an appropriate liquid and means for mixing this vapour with the heated air, and is characterised by the juxtaposition with the mixing chamber 4 of a settling chamber 7 separated by a grid 6, allowing the best possible homogenisation of the air/vapour mixture and the removal of condensates which can be formed.

Description

APPAREIL A USAGE MEDICAL DESTINE A EMETTRE UN FLUX
D'AIR CHARGE DE VAPEUR D'EAU
La présente invention concerne les humidificateurs d'air destinés à émettre un flux d'air chargé de vapeur d'eau ou tout autre liquide approprié, comme ceux décrits dans les brevets francais n" -FR 8305486 et ne FR 8409532 et utilisés dans le traitement médical des inflammations de la muqueuse nasale, telles que les rhinites
La présente invention, tout en respectant le principe général de l'invention ci-dessus désignée apporte encore des solutions simplificatrices conduisant à la-réalisation d'appareils encore plus simples et qui seront de prix encore plus faibles.MEDICAL APPARATUS FOR TRANSMITTING A FLOW
AIR LOADED WITH WATER VAPOR
The present invention relates to air humidifiers intended to emit an air flow charged with water vapor or any other suitable liquid, such as those described in French patents n "-FR 8305486 and not FR 8409532 and used in the treatment medical inflammation of the nasal mucosa, such as rhinitis
The present invention, while respecting the general principle of the invention designated above, also provides simplifying solutions leading to the production of even simpler devices which will be of even lower price.

L'invention ici proposée est constituée par un réservoir d'eau ( 1 )d'une contenan#ce de l'ordre de 0,5 litres. Un évaporateur (2) est constitué par une résistance cylindrique placée verticalement entourée par un cylindre permettant la circulation de l'eau entre ce cylindre et la résistance.The invention proposed here consists of a water tank (1) with a content of the order of 0.5 liters. An evaporator (2) consists of a cylindrical resistance placed vertically surrounded by a cylinder allowing the circulation of water between this cylinder and the resistance.

L'eau liquide pénètre par le bas dans l'évaporateur et sort sous forme de vapeur par un tuyau (3) placé sur la partie haute de l'échangeur et transportant la vapeur dans la chambre de mélange (4). L'évaporateur comporte un isolant destiné à éviter lechauf'age excessif de l'eau du réservoir.The liquid water enters the evaporator from below and exits in the form of vapor via a pipe (3) placed on the upper part of the exchanger and transporting the vapor into the mixing chamber (4). The evaporator has insulation to prevent excessive heating of the water in the tank.

Un courant d'air chaud pénètre dans la chambre de mélange grâce à un ventilateur et une résistance chauffante régulée en température (5).A stream of hot air enters the mixing chamber thanks to a fan and a temperature-regulated heating resistor (5).

Les flux d'air et de vapeur sont injectés dans la partie supérieure de la chambre de façon à creer le maximum de turbulence par impact sur les parois de cette chambre.The air and vapor flows are injected into the upper part of the chamber so as to create maximum turbulence by impact on the walls of this chamber.

Le mélange air-vapeur d'eau passe par une grille (6) située dans la partie basse dans une chambre de tranquilisation (7) destinés é éliminer les gnutelettes liquides qui pourraient etre présentes et à obtenir un mélange homogène.The air-water vapor mixture passes through a grid (6) located in the lower part in a stilling chamber (7) intended to eliminate the liquid gnutelettes which could be present and to obtain a homogeneous mixture.

Un diffuseur de sortie (8) permet l'inhalation du mélange par le patient. La consigne de régulation pour le chauffage de l'air est donnée par un capteur de température placé au niveau du diffuseur de sortie. -La puissance de l'évaporateur est asservie à sa température de sortie.An outlet diffuser (8) allows the patient to inhale the mixture. The regulation set point for air heating is given by a temperature sensor placed at the outlet diffuser. -The power of the evaporator is controlled by its outlet temperature.

Une valve de sécurité permet enfin de maintenir la pression dans le réservoir à un niveau très faible. A safety valve finally keeps the pressure in the tank at a very low level.

Le système ainsi conçu comporte un certain nombre d'innovations
Les écarts de pression par rapport à la pression atmosphérique sont très faibles ce qui permet d'améliorer la sécurité du système.The system thus conceived contains a certain number of innovations
The pressure deviations from atmospheric pressure are very small, which improves the safety of the system.

2. Le vaporisateur isolé vertical permet de localiser les températures élevées dans la partie la plus protégée de la machine.2. The vertical insulated vaporizer makes it possible to locate the high temperatures in the most protected part of the machine.

3. La position de ce vaporisateur (vertical et entièrement plongé dans l'eau liquide pour sa partie externe) permet la production régulière de vapeur sous faible pression.3. The position of this vaporizer (vertical and fully immersed in liquid water for its external part) allows regular production of vapor under low pressure.

4. La présence d'une chambre de mélange et d'une chambre de tranquillisation séparées par une grille permet l'homogénéisation la plus parfaite du mélange air-vapeur et la suppression des condensats susceptibles de se former. 4. The presence of a mixing chamber and a stilling chamber separated by a grid allows the most perfect homogenization of the air-vapor mixture and the elimination of condensates likely to form.
