Definitions

• the invention relates to a room nebulizer for inhalation treatment of people with treatment liquids nebulized by a gaseous drive medium, each in a container with a nozzle nebulizer accommodated therein.
• Rough inhalers are primarily used for the inhalation treatment of people with mist and medication mists in a closed inhalation room.
• a drive medium for example compressed air
• the individual inhalers supplying the patient with an aerosol stream via a mouthpiece are limited to the inhalation treatments of one patient at a time.
• exposed nebulizer nozzles blow compressed air into open glass dishes containing the treatment liquids, from which the nebulized substances rise into the inhalation room.
• the fungi, bacteria and pathogens increasingly adhering to the attacked areas thus get into the treatment liquid and, through their nebulization, directly into the patient's organism via the respiratory organs.
• German patent specification 33 16 322 already discloses a single inhalation device for generating temperature-controlled aerosols for the inhalation treatment of people, in which atomized treatment liquid from containers with nozzle nebulizers via a mist collecting channel and a heatable inhalation line connected to it through a mouthpiece Patient is fed.
• this single inhalation device contamination of the treatment fluids by impurities originating from the patient is excluded, since the device under pressure as a result of the compressed air at the nebulizer nozzles causes the patient to breathe back or cough up. through the mouthpiece, the inhalation line and the mist collecting channel to the containers.
• this device has the disadvantage that it is only suitable for inhalation treatment and, moreover, only one patient can be treated at a time.
• the amount of air supplied by the nozzles in the containers is not sufficient for some patients, so that such patients breathe in uncontrolled, unfiltered, unheated room air through the corners of the mouth.
• the inhaled air which is dependent on the patient's breathing behavior and cannot be controlled by the attending physician, makes the concentration of the medicament mist in the air breathed in altogether unpredictable. In many cases, however, the correct concentration of active substance in the breathing air is important.
• the invention has for its object to provide a room nebulizer that supplies the patient with a constant amount of the nebulized treatment liquid and does not deliver a worse treatment result for impurities entered into the treatment room and is easy to clean.
• This object is achieved according to the invention in that, in the case of a room nebulizer of the type mentioned at the outset, the containers are attached to a carrier according to the invention and are each connected to the inhalation space by a mist outlet.
• the containers and the nozzle nebulizers located therein are only connected to the inhalation space via the mist outlets assigned to each individual container. Since a pressure which is higher than the atmospheric pressure prevailing in the treatment room is present inside the containers filled with treatment liquid due to the gaseous drive medium flowing in via the nozzle nebulizer, contamination and germs from the treatment room cannot penetrate into the containers through the mist outlets. Contamination of the treatment liquid by bacteria present in the treatment room, for example released by coughing up the patient, is excluded.
• the arrangement of the nozzle nebulizers in the containers combined in the device body also means that they cannot be contaminated by contaminants from the inhalation space.
• the mist outlet can consist of a gas-tight line that closes the open side of the container.
• the containers are attached to a carrier which also serves to accommodate the lines for the drive medium.
• the containers can also be arranged in a housing serving as a support with through openings for the mist outlets.
• the concentration of the nebulized constituents of the treatment liquid in the treatment room can be adjusted to that for an optimum in the case of presettable atmospheric conditions in the treatment room by adjusting the amount of the gaseous drive medium therapeutic success necessary measure can be set. Due to the sufficient amount of air enriched by mist, which is always guaranteed in the treatment room, the disadvantageous consequences of fluctuation in the concentration of the mist in the inhaled air that occur during single inhalation due to sighing are eliminated.
• the drive medium preferably medically pure compressed air
• the drive medium can be directed to the supporting frame through a central feed.
• lines lead from the central feed to the individual nozzle nebulizers. Due to the central supply, only a connection of the room nebulizer to a compressor delivering the drive medium is necessary. As a result, the number of necessary through openings and thus the number of possible leaks are reduced.
• a quick-change coupling allows the room nebulizer to be easily removed from the corresponding counterpart of a drive medium supply within the treatment room.
• the device can be cleaned, disinfected and filled with fresh treatment liquids in just a few simple steps.
• the containers which preferably consist of safety glass and hold the treatment liquids, considerably reduce the risk of injury.
• the room nebulizer 1 consists of a supporting frame 2, on the underside 3 of which, along the circumference, containers 4 for treatment liquids are fastened with screw closures 5. Compressed air flows via a central feed 6, a line 8 on the horizontal distribution head 7 and outgoing lines therefrom to nozzle nebulizers 9 located inside the container 4.
• a gas outlet 12 connects to the screw cap 5 of the container 4 in a gas-tight manner.
• the side outlet 12 provides the is the only connection between the container 4 and an inhalation space (not shown in the drawing).
• the mist outlet 12 has in the upper region of its lateral surface 13 a passage opening 14 for the line 8 supplying compressed air.
• the nozzle nebulizer 9 located inside the container 4 consists of a cylinder 10, which in an end section 19 has an inflow duct 15 which receives the compressed air supply line 8 and which opens into a radial outlet duct 16, and an annular flange 17 with an axially parallel one lelen through hole 18, which is penetrated by an axially displaceably mounted nozzle 21 with a suction channel 22.
• the outflow end 23 of the nozzle 21 lies in the mouth region of the radial outlet channel 16.
• the room nebulizer is put into operation by supplying compressed air of approximately 3 bar to the nozzle nebulizer 9 via the central feed 6 and the lines 8 connected to it.
• the compressed air flowing into each container 4 through the line 8 sucks the treatment liquid through the opening 23 of the nozzle 21 after passing through the outlet channel 16 and atomizes it into a mist which is thrown against the container wall on which the large mist particles are drip off, while the fine, inhalable mist particles reach the top through the mist outlet 12 into the inhalation space not shown in the drawing.
• each nozzle nebulizer 9 Due to the assignment of each nozzle nebulizer 9 to a container 4 with a separate mist outlet 12, it is possible with the nozzle nebulizer according to the invention to simultaneously simultaneously treat various treatment liquids, for example a brine and several medicament solutions in any combination.
