Description

Modular device for the humidification of breathing gas

The invention relates to an apparatus for humidifying the respiratory gas.

Such devices contain a functioning as a water dispenser device, which is designed typically either as a refillable tank for providing a water supply, or is a continuous source or contain an element which itself gains water and makes available, for example, by condensation of moisture from the air or by chemical synthesis, wherein a reservoir may be provided for this water extraction element further, but need not be. In addition, not necessarily, but typically present other elements, such as a means for heating the water or the respiratory gas, for example in the form of a heater, a water supply occluding device, e.g., a cover, a terminal for connection to a breathing gas hose or a terminal for connection with a breathing gas supply. A typical use of such humidifier is carried out in connection with respiratory air supplies, which are used in a CPAP (Continious-more positive Airway Pressure). Applications for so-called bilevel, APAP breaths and home ventilation are also possible. .Such humidifier in the clinic are also used in intensive care ventilation. To avoid drying out of the airways, it has proven particularly with longer ventilation phases as advantageous to carry out a humidifying the air we breathe. Such wettings of the air can also be realized in other applications.

The known humidifiers are typically constructed such that the respective humidifier associated with a particular ventilator and a particular breathing mask with breathing tube. This hinders a universal usability and in particular a configu- gurability an overall system depending on the particular application requirements. Furthermore, the known humidifier can not meet all the requirements placed on a simple yet thorough cleaning ability, for example.

Object of the present invention is therefore to construct an apparatus of the aforementioned type in such a way that a universal and simple to use and to clean device is provided. In particular, it is contemplated to provide a device which consists of a basic module and extension modules of many. In addition, exchangeable, mutually substituting Elernentgruppen are provided which nit an individual adaptation to the needs allow the user. The aim of the invention is to provide a humidifier that accompanies the user lifelong. Depending on the user's requirements, any modules can be updated or replaced. Above all, it is contemplated that the humidifier inventive devices, depending on the related add-on modules with ventilation of any type use is.

This object is inventively achieved in that the respiratory gas humidifier of a basic or functional element consists and any supplementary or replacement modules as needed, easily, safely and quickly can be adapted. The humidifier comprises at least one modular exchangeable against an alternative portion of the component.

In a typical embodiment of the respiratory gas humidifier is constructed from individual modular functional elements. The humidifier is provided with a water supply, a water supply and a hose connection. The hose connection is formed, for example, nozzle-shaped and is used for connection of a breathing tube. the supply of the humidifier with breathing gas via a supply connection. The breathing gas is provided by a breathing gas supply. The supply connector can also serve as the coupling of the humidifier to the breathing gas supply. Above the water supply comprises a flow space extends. The water supply can be closed by a lid and be connected to the supply terminal and the hose connection. The water supply may be arranged in the region of the lid. The exchange modules are especially provided to individual functional elements can adapt to the user's individual needs. it is possible, as to do justice by replacing the corresponding part of subsequent changes to the requirements for the device with little effort. The device changes with the requirements by the user and can be used over a long period of this therefore. The modular construction of the device can be adapted to individual needs.

The water supply can be selected in various sizes depending on the demand for water and space, whereby the presence, type and performance of a water heater or elements for securing against tilting of the water may be added as needed. Required higher pressure of the breathing gas, which in simple air duct too much noise arises the air duct can, for example, integrated into the lid of the water supply, be exchanged for one provided with a noise attenuation model. Various connection elements adapt different hoses and additional compounds, such as measuring and control cables.

A measuring line for pressure, flow, humidity, or similar applications can be arranged adjacent to the respiratory gas tube and / or within the respiratory gas tube. The breathing gas hose is connected, for example via an exhalation with a hose coupling a breathing mask. Alternatively to the breathing mask all known interfaces can be used on the patient side, for example tubes, needles or similar components. The modular design of the components and separable from each other, it is possible to make them independent of each other such that each individual optimized properties can be provided. So for example it is possible to optimize the properties in terms of optimized cleanability. Also, the humidifier can be configured such that it is suitable for very high ventilation pressures. Moreover, it is also possible to form the cover and the water supply universally and to make the supply terminal and the hose connector adapted to particular breathing tubes or ventilation equipment in the region of its side remote from the lid member. The tube connection and the supply terminal can be used as adapter pieces thereby that virtually any selectable separate devices via a apart from the universal adapter pieces formed humidifier couple together.

The supply connection and the hose connection may partially extend along a flow tubusförmig main axis, at least. The supply connection and the hose connection are then preferably arranged with respect to a ground plane of the lid on a raised platform that partially defines the flow space. In this way, an increased drain protection is achieved and overfilling of the water tank.

In the region of the hose connection has a substantially cylindrical outer wall coaxially disposed to the hose connector connection runs, which is provided for connection to a measuring conduit which extends here, for example, within the respiratory gas tube. In an advantageous embodiment, the modular system includes modular, interchangeable elements for the water supply and corresponding unified closure systems for simple, safe and well-to-handle connection.

Another modular replaceable component is a means for introducing water or steam into the breathing gas. In particular, this may be in the region of the air duct or in the duct on one or on a water surface, a water nozzle, a Wasservernebler, a preferably one-sided water-permeable membrane, a condensed water generating Peltier element or a fuel cell effected.

Another modular replaceable component is a device for heating the water or the already moistened or even to be humidified respiratory gas

Additional elements can be added as needed, for example to about measured or input data to achieve a required adjusted optimized control of the respiratory gas, and provided its parameters. Sensors on the user, environmental sensors, sensors on the device and its elements, as well as read-in data, for example the remote connections, trie approximately over telemedia be added, displayed, stored, processed and used for control operations, in a preferred embodiment in the form of a closed control circuit that involves triggered by control operations respective changes of current values ​​in its control behavior. And automatic warning signals can be generated, such as when the water supply is too low, cleaning is required or if other limit violations threatening.

Additional elements may also serve the additional or sole water production, such as fuel cells or Peltier elements, the advantage is that the water extraction is side effect of concurrent other device function, for example, a power generation or heating. Also, devices may be present, which make up moisture from the ambient air used in other ways and to introduce, for example, by a semi-permeable membrane for water into the flow of breathing gas.

Additional components may also serve to simplify the handling. Befüllhilfen, handles, additional attachments for other types of stands, cleaning aids, etc. can be provided so that the user - especially when traveling - all useful tools has on hand. The modular design of the use of the device is equally possible with and without such elements. Further, the power supply can be either a generator or by elements which are made flexible access to alternative power sources, for example, according to other standards, allow, by corresponding elements such as battery or battery components, fuel cells, transformers or transducers are inserted, if necessary. In particular, it is proposed that the operation of the humidifier with all possible / common voltages, for example 6, 12, 14, 24, 48, 110, 220, 240 volts DC - to enable and / or alternating current.

A particular efficient form of humidification can be effected by an ultrasonic nebulizer, simultaneously being separated by a barrier filter the water supply and thus the highest possible purity of the humidified respiratory gas is ensured. Also, this module can be added modularly and / or replaced.

The total bandwidth of the humidification of breathing air from the breathing newborns up to the intensive care ventilator (up to 120 1 / min and up to 120 mbar) can be made possible thanks to the modular design variable. This is made possible with the adaptability to all conventional ventilators.

A compact apparatus structure is supported in that extension members are arranged for a pressure measuring both in the region of the supply connection and in the region of the hose connection.

A simple components geometry in particular for the support of an injection-technical production is achieved in that the extension elements of the pressure measuring line is at least partially extending along a flow axis of the main supply port and the hose connection.

A stress-resistant connection of the components, for example, each be provided in that the supply connection and the hose connection are connected by at least one pin and at least one recess form-fitting manner with each other.

In one embodiment, the supply connection is provided with a terminal adapter, which serves for connection to the breathing gas supply. The terminal adapter is provided with a detent which engages in a pushing together of the humidifier and the breathing gas supply in a corresponding counter element of the breathing gas supply. The lock has an actuating element which cancels the locked state in a manual press, so that the humidifier can be separated from the breathing gas supply in a simple manner.

A lateral boundary of the humidifier may have a contour that is adapted to a contour of the breathing gas supply. This makes a very compact overall design is possible with a joining of the humidifier and the breathing gas supply. In addition, the humidifier may comprise an electric terminal zusammenkoppelbar with a mating terminal of the breathing gas supply. For fixation of the humidifier to the respiratory gas supply, a locking element is preferably provided that can be in the form of a click closure. Also can be carried out over such a connection, a coupling of the breathing tube to the respiratory gas humidifier. Above the water supply comprises a flow space extends. These modules are interchangeable and can be connected together by the described interfaces.

To avoid an accidental leakage of water and to avoid an excessive filling it is provided that the supply connection and the hose connection are disposed on a raised base of the lid.

A particularly functional geometrical configuration is provided by the fact that both on power supply connection and the hose connection have an essentially angular design.

The manual handling in a mating and unmating of the individual modular elements is facilitated that at least one extension member for the pressure measuring line is arranged inside the lid.

A particularly easy to mount construction can be achieved in that the extension part is constructed as a plate-shaped connecting element.

A simplified geometry of the individual elements can be achieved in that the extension piece has a hose connected socket-like connecting parts.

To support a low-flow guide is provided that the supply connection and the hose connection in the direction of main flow axis extending at least partially cylindrical.

A very simple handling during filling of the humidifier may be provided in that the lid has a water supply.

In a use state of a device arrangement is such that the breathable gas supply is connected via the hose connection to the breathing gas hose and the supply terminal to the breathing gas supply.

A simple manual handling is also supported by the fact that the humidifier in the region of the respiratory gas supply faceable expansion has a releasable locking. It is also contemplated that the hose connector via a releasable locking with the respiratory gas tube is connectable.

A large mechanical strength is achieved in that the cover has a recess for fastening of the hose connection.

In particular, it is contemplated that the hose connection engages with a fitting connector into the recess and sealed by a sealing ring opposite the recess.

In addition, the mechanical strength can be increased by the fact that the cover comprises a recess for attachment of the supply connection.

Also with respect to this constructive implementation, it is advantageous that the supply terminal is engaged with a fitting connector into the recess and sealed by a sealing ring opposite the recess.

A spray water formation within the respiratory gas humidifier can be avoided in that a baffle plate is arranged in the region of a junction of the supply terminal in the lid.

According to one embodiment it is provided that the baffle plate is formed as part of the supply connection.

Alternatively, it is also possible that the baffle plate is formed as part of the lid. An improved Positioniersicherheit by providing a positive connection can be achieved in that the supply connection and the hose connection of at least one positioning pin are positively connected to one another.

A simple assembly is supported in that the positioning pin is inserted fixed in a recess of one of the terminals and in the other of the recesses engages with play.

Simple handling is achieved that all modules can be connected together by pins or groove and spring mechanisms. So just to be plugged into one another.

A long Befeuchtungsdauer without maintenance is achieved by the water supply modules can hold up to 5000 ml liquid, or in that a continuous afterflow of water there.

A low power consumption of the device is achieved by partially the devices heat the respective ventilator is used to heat the water.

In order to avoid condensation, a module includes a heated air supply and insulation.

The relative humidity increase is mainly dependent on the air and the water temperature. The following table shows the saturation of the breathing air with water, wherein the saturation is dependent on the temperature.

With another module the device is operated on demand. A sensor detects the ambient humidity and ambient temperature and adjusts the change in Anfeuchtungsleistung. Here, the user can continue to control the degree of humidification and temperature of the air free. The device converts the patient settings only within sensible limits. As the air we breathe, for example, always a minimum destanfeuchtung provided and excessive condensation in particular avoided in the hose.

With an additional module for the demand-controlled control of the humidifier is controlled Atemgasbefeuchter- the performance over a biofeedback of the patient. A sensor detects the current of the patient and the humidification Atemgasbefeuchterleistung regulates the required amount. As measuring parameters can be selected: Expiratory and / or inspiratory humidity, Expiratory and / or inspiratory air temperature, a measure of the surface moisture of the mucous membranes of the upper airways, or a combination of all. In parallel, the loss flow concerning a possible mouth expiration or even the loss of flow through nose / mouth leak can be registered and the Atemgasbefeuchterleistung be up-regulated accordingly.

The evaluation of the measuring data is preferably carried out by means of fuzzy logic and / or neural networks.

the above-mentioned modules are preferably combined in order to ensure an ideal demand humidifying and warming of the breathing gas at all times. The humidification can be set or controlled as required. This can be done in stages or continuously.

The moisture content and the temperature of the respiratory gas are ideally controlled either in an automatic mode and / or determined by the user and or set to be selected within limits. The automatic function is part of a comparator, which also converts the user input. The unit controls one of the selected and / or required values. A sensor detects the ambient humidity and / or ambient temperature and / or composition of the ambient air and / or brightness and / or climatic parameters and / or the flow of breathing gas and / or the pressure of the breathing gas and / or possibly present Lek kagen and / or the current humidification of the patient and / or the expiratory and / or inspiratory air humidity and / or the expiratory and / or inspiratory air temperature and / or moisture to the mucous membranes of the upper respiratory tract and / or a temporal change of the measured variables and / or a change of the measured values ​​and regulates upon a change of the degree of humidification and the temperature of the humidified respiratory gas.

The evaluation of the measuring data is preferably carried out by means of fuzzy logic and / or neural networks and / or by suitable algorithms by a Comparator. This compares the actual and the desired state. If the actual and desired state vary in at least one measured parameter of the comparator sends a corresponding signal to the controller. This regulates the power until the actual corresponding to the target state.

As sensors may be used suitable optical, electronic, mechanical, magnetic sensors.

Alternatively, you can select between a wired or telemetric transmission of the measured data from the patient to a humidifier.

Another modular replaceable component is an apparatus for energy supply. The Atemgasbefeuch- ter is typically operated with a respirator. In the event that the user is a mobile unit that wishes a power supply with solar cells, rechargeable batteries, preferably rechargeable battery, fuel cell or miniaturized internal combustion engines is also possible.

Especially in the case of mobile use of the Verkipp- security of the stored water is important. Modular interchangeable components are in the range of water supply and enable, for example, characterized in that the water is held in a porous member, a Verkippschutz. Ideal there is no free liquid lot more.

An easy fillability is realized in that a funnel for filling rate pops up from the water supply.

As an additional module of the filling level can be detected in the humidifier by means of a sensor system. Thus, selectively further if necessary water can be supplied to the humidifier, for example by a pump or an electrically operated valve. Benefits arising: It is always very little water in the humidifier, so that a problem exists Verkipp barely. In addition, constant conditions for moistening prevail.

The water level or the amount of water stored is detected in another embodiment, by means of a scale, which is arranged in the region of the humidifier.

Alternate embodiments of the sensors: - The etc. actuates a switch, reed contact float. The float can also act directly on the supply valve.

- measuring the electrical conductivity of the water, If the water level under the two electrodes in the humidifier, so no current can flow between the electrodes Optical sensors, such as reflections from the water surface) Additional modules allow communication or informing the user, for example on current operating conditions. When, at the choice module, the current humidity and heat of the breathing gas and / or the set values ​​for these parameters, as a percentage or absolute value is displayed. With another module, the user can adapt a display of its useful life, storage of values ​​for life and and adjustment of the useful life. An optional cleaning indicator, which may be coupled to the module "useful life", it indicates to the user the recommended cleaning and / or maintenance schedule. The communication can be extended by a further module to a voice recognition and / or speech output. The humidifier can thus, for example, bedridden patients a remote control enables a speech recognition and possible failures and / or current state / data via the voice output communication. Other modules allow communication with intelligent technology and / or the sending and / or receiving and / or receive messages. Thus, the humidifier on or telemetric and / or wired (display ads, SMS, email, infra-red bluetooth) information sharing Send current states / Show. The display can be for example in the form of organic light emitting diodes (OLEDs). At the same time, the communication also enables remote adjustment, remote maintenance and / or remote access of humidifier parameters. For example, if only a little water in the reservoir of the humidifier time sends a message.

The modules enable comprehensive monitoring of temperature and humidity, as well as of important and informative function values. In addition, automatic warning signals in case of errors or deviations are generated and displayed or sent.

The design of each configured device is largely arbitrary. interchangeable covers, veneers and top shells are available for the device. These are different in shape, color and design may be preferred modeled on the design of the breathing gas supply being used. Alternatively, the wishes of the customer, by providing a range of different shapes, colors, designs and materials (especially adapted individually) are met. The replacement of the covers / Covers can be done by the user himself, because the mechanism is simple and self-explanatory. Yes on the component are, for example tongue and groove, rubber-mounted connectors or similar components are used.

For water supply, the user can, according to its needs, choose different modules. For domestic use, a continuous source of water, for example via a connection of the humidifier to the house-water line can be realized. Here it is also possible to directly select a hot water inflow. Thus, no more heating is required.

An improvement of the handling and a reduction in the cleaning effort is provided by a module, that the humidifier is supplied with sterile water. The water is not filled in the humidifier. The sterile water supply, for example, a plastic bottle is replaced as soon as it is empty. This option is eg for bedridden patients suitable caregivers must therefore devote very little time for maintenance of the technology and can fully devote to nurses.

By insulation of the walls of water supply heat losses can be avoided. The heating of the water is more effective, faster and more energy efficient. Can thus be achieved with a constant power supply a higher degree of moistening.

A longer Befeuchtungsdauer in patients with increased moisture requirements, for example by mouth breathing, can be achieved by modules that allow condensation of atmospheric moisture.

In one embodiment, the humidity will be forced by local temperature reduction of condensation by the use of a Peltier element. In an area of ​​the Peltier element, in which the low temperatures are present, the condensate is collected and supplied to the water supply. Alternatively, the Peltier element can directly cool the chamber. At the same time the warm side of the element is used in order to preheat the air before it moist sweeps through the aeration and absorbs water. A longer Befeuchtungsdauer in patients with increased moisture requirements, for example by mouth breathing, can also be achieved through the use of modules that provide hygroscopic materials. In an embodiment of the ventilation tube is provided for this purpose with a coating by stroking the moist air exhaled by the patient. The wall between the breathing tube and the outer sheath is made of a moisture-absorbing material. A coating of the partition wall with HME capable materials increases the moisture absorption. The ventilation air coming from the source of breathing gas, at this sweeps along wet wall and absorbs the moisture, and supplies them to the patient. In an alternative module is located in the inside of the mask a hygroscopic material. In another variant adaptable a silica gel is used. The silica gel removes the air exhaled by a lot of the moisture. At periodic intervals, the silica gel is heated. As a result of heating, the moisture is given off again and is fed through a tube to the water supply.

A module specifically for mobile use a respirator with humidifier aims to have practically no elemental lead water with them and energetically of electricity, particularly of heavy batteries to be dependent.

In an embodiment of this module, water is produced from elemental oxygen and hydrogen in a fuel cell. Generated in this process energy is used for the device, the humidifier and if necessary. The heating operation. Water may also be in other aggregate form, for example as ice are stored. This can achieve a Verkipp- or outlet contactor and, in addition, it is possible to evaporate only the area needed for moistening each portion of ice specifically, for example, with radiation. This module further provides respiratory phase depending perform the vaporization of the ice by means of radiation. the control algorithm is preferably set such that the vaporization is carried out shortly before inhalation through a detection of the respiratory phases. As trigger the pause between expiration and inspiration can serve. This makes the breathing gas is only dampened when the patient - physiologically meaningful - humidified breathing gas needed. The water supply lasts longer.

In another module, the water is incorporated into a gel, it results therefrom a Verkipp- or outlet contactor because the gel can not or can only flow slowly at a misalignment of the humidifier. The gel can be heated, such as water and gives off the moisture, analogous to a water surface where the sweeping air. In addition, a gel is preferably selected which stores heat longer than water, whereby the energy consumption reduced.

The water supply may be formed by an alternative to dialing module also in the form of a bird bath. Here, only the currently taken to be humidified and or heated water quantity of water supply. The water supply lasts longer and it is less energy for heating, for example by means of radiation, the water consumed. In a preferred embodiment of this module, water is supplied to the respiratory phase dependent Befeuchterraum. the Regelalgorythmmus is preferably adjusted such that the evaporation and or is performed on eizung of water shortly before inhalation through a detection of the respiratory phases. As trigger the pause between expiration and inspiration can serve here. This makes the breathing gas is only dampened when the patient - physiologically meaningful - humidified breathing gas needed.

A water level independent flow in the humidifier is ensured by the modulus of the water level compensator. the water supply is always kept in an excellent position to air stream through a spring. The spring presses the water supply successively upward, and the water stored quantity decreases. Regardless of the amount of water always has water on top of the same height. Characterized that the degree of humidification is maintained constant is achieved. In addition, the sound development remains constant and does not change with decreasing water level and louder.

Filling of the water supply is performed depending on the selected water supply module. For the continuous water supply, for example via a connection of the humidifier to the house-water line, then a self-filling of the water supply, for example the valves, vacuum, float switch or the like.

The humidification of breathing air takes place in the individual modules for storing the water inherently often in different ways. In principle, however, is provided in order to use various principles of humidification during the interchangeability of the modules offer the optimal / desired solution here.

In Membranbefeuchtern the air and the water side are separated by a semipermeable membrane, for example, Gore-Tex, Nafion membrane from each other. The membrane can pass water in the direction of Befeuchtungsraumes. In this way, a large contact area of ​​water and air can be realized with optimum flow guidance and low noise emissions.

Preferably, the water supply can be realized in the region of the respiratory tube. Particularly preferred consist in the region of the respiratory tube in a plurality of, preferably three-dimensionally oriented to each other in arrangement areas of contact between semi-permeable membrane and breathing gas. Ideal a widespread fine capillary network is formed, that a very large contact surface underwater breathing gas provides. In one add-on module, the heating may be arranged in the region of the respiratory tube simultaneously. heating are preferred, and the membrane is designed to allow the heating by the heated areas of the membrane a reinforced passage of water through the membrane. The heating can also be controlled as needed and very accurate. In this way, a condensation of water vapor in the area of ​​the membrane facing the ventilation air, is avoided. In addition, the control can be such that the respiratory gas is more or less dampened in accordance with the respiratory phases.

For modules that operate the humidifier according to the principle of a drip, the water supply is located above the water outlet. The opening of the water for humidification out is designed such that no water dripping due to the surface tension of the water. the viscosity of the water is reduced by brief heating of the water, decreases the surface tension and heated water dripping from the tank. the critical surface tension is reached again by cooling the opening, it drips water stops. A very dynamic and appropriate regulation of the amount of water removed can be achieved by a corresponding timing of the supply of water for humidification, reached in accordance with the respiratory phases. just before the inhalation of water to the humidification is preferably supplied.

Alternatively, the Tropfbefeuchter can also be designed such that a heatable metal plate having small holes. On this record, the water supply is located. The water is thus directly on the metal plate. The size of the holes is chosen so that due to the capillary forces flows no water. Now, if the plate is heated, the water viscosity and water changed exits. The regulations of the power supply so the water supply can be regulated for humidification.

In another embodiment of the Tropfbefeuchters several, for example parallel pipes are filled with water. These tubes may extend along the respiratory tube. The tubes have fine holes / openings. The apertures may be opened in a controlled / closed. occurs here, as the drip humidifier, only water when the tubes and the openings or be heated. Alternatively, the humidifier work in two modules on the principle of dropping, the openings electronically, mechanically, pneumatically or magnetically opened or closed.

The heating can also heat the water indirectly. Alternatively, another module offers the option of heated air in the humidification to conduct. is the air which is led into the humidifier instead of water, is heated. This more moisture can be absorbed at a low water temperature.

Another module for heating the water is a thin, electrically conductive layer which is disposed in the water supply.

The thin layer may preferably lining the entire water supply. A particularly large heat transfer area is created. The electrically conductive layer may be, for example, vapor-deposited and consist of any suitable materials that have a good heat transfer, in particular is intended to gold, silver, copper and similar metals. The interface to the water is preferably electrically insulated.

Suitable for the insulation are all electrically non-conductive materials having good thermal conductivity. The insulating layer is typically very thin, preferably in the range of a few microns and nm thick and may for example be vapor deposited. The electrically conductive layer serves not only the heating of the water. In particular, it is envisaged to determine the actual water temperature over the electrically conductive layer and also to determine the water level. For example, the temperature of the water can in phases in which not heated are determined in order then to adjust the heating output accordingly. Also, the filling height of the water may be determined in stages in which no heated. The heating power can thus be adapted to the decreasing water level.

As an energy source for the heating of the air, for example, the warm air "out" of the electronics can be used. It is also possible to use a Heizspindel, as is used in hair dryers apply. both sources are preferred used simultaneously. The breathing gas is continuously preheated by the hot exhaust air of the electronic components and also upregulated by suitable means to the desired temperature. The heating of the air we breathe can be done atempha- senge controls.

Another module provides the structure of a Einspritzbe- humidifier according to the principle of an inkjet printer (piezo or bubble jet). The fine outlet openings are preferably arranged in an elastomer part so that, for example, calcium deposits can be removed by deforming the elastomer part. The injection can take place in a diffusely humidification and / or the ventilator device to the motor, blower or fan.

An alternative module provides provides a pump which water applied in very small quantities, preferably directly to the fan wheel or an upstream atomisation. Due to the high rotational speed and the small pulsatile delivery quantity, the water is immediately atomized and mitge- with the air flow cracks. The modules described allow rapid and precise timing controllable atomization.

Through an additional module to the respiratory air and / or humidified respiratory air can be heated to the desired temperature by at least one heater grid, which is located in the airway. these modules are preferably used together with a non-continuous humidification of the respiratory gas. In particular, it is contemplated to control the humidification so that the patient in the inspiration phase of a higher moisture and / or temperature is provided as in phase of the expiration. This water and energy are used as needed and at the same time economically.

According to another embodiment, the water is pumped by a circulation pump area in the Atemgasbefeuchter- and returns through one or more walls, grid structures or similar means in the tank. Through a distribution system, for example, a plurality of nozzles or channel-shaped distributing channels the best possible wetting of the walls is achieved with water. The breathing air flows over the walls and absorbs the moisture.

Conceivable embodiments of the pump: gear pump, piston pump, pump turbine, pump with pulsating elements, such as membranes. It may valves for setting the conveying direction, peristaltic pumps, are used long sweeping the hose elements, impeller, eccentric, Seitenkanalrad- or centrifugal pumps.

a partition wall having an opening are arranged according to a further embodiment, above the tank. If the opening is arranged at a distance from the outer wall of the tank, a Verkippschutz of the humidifier is given by the partition wall.

Generally, it is conceivable to design the entire Anfeuchtebereich including the partition as a removable cover of the humidifier, thus achieving a slight tire nigbarkeit.

Optionally, the water for improved wet performance Atemgasbe- can be heated by a flow heater.

That of humidifier is explained in detail below.

By a module, only a subset of the breathing gas is humidified in the sense of a bypass. Preferably, this module can be complemented by a control unit, wherein the patient provided by humidity and temperature can be controlled by the adjustment / regulation of the mixing ratio between wetted and non-wetted breathing gas at a relatively constant heat output. The advantage of this module is the very quick scheme that can be particularly breath as adjusted several times.

Preferably, it is contemplated to control the humidification so that the patient a higher moisture and / or temperature is provided in the inspiration phases than during periods of expiration. Also beginning or within a breathing phase, for example, be moistened endinspiratorisch different.

Preferably, it is contemplated to control the humidification so that the patient in the phases of starting and ending inspiration lower moisture is provided as in phase of the average expiration. This results in a lower moisture in the dead space and the condensation in the hose can thus be effectively reduced.

Particularly preferred is thought to control the humidification so that the patient's breathing phase-dependent and / or event-dependent provide the respective required humidification and temperature control of the breathing air. This can be synchronized with the detection of respiratory phases and / or the detection of events which affect the patient's breathing, for example, apnea, cough, swallowing, done by the ventilator.

Various components such as mask and / or tubing as water and / or heat accumulator will be equipped with the module "re-wetting". The mask and / or the hose and / or the humidifier are lined (moisture HME heat exchanger) from the inside with a suitable water-retaining material which binds the Feuchtigkleit the exhaled air and emits it to the breathing air in the next Einatemzug. Further, in the mask, a humidifier can be integrated.

In a Ergänzungdmodul described above HME principle will be extended. The HME component is significantly larger and constructed such that within the matrix at least the humidity and the temperature remain substantially constant and substantially correspond to the values ​​of the exhaled air here. This is ensured by a large surface area of ​​the matrix which is interspersed with fine internally hollow capillaries. The oxygen and carbon dioxide exchange takes place inside the capillaries by diffusion. This module is elastic and can be moved mechnisch, resulting in a ventilation. Alternatively, a common source of breathing gas is anschlißbar.

In the following, the input will be explained in more detail air, with a return-VerkippSicherung - is provided (bulkheads for the prevention of reflux, VerkippSicherung). By walls in the bottom region of the container Wasservorrat- water is retained upon tilting of the water tank. It can be expanded to each other several walls, for example concentric. In addition, the height of the walls may increase to the supply terminal or to the ventilation port out so that the necessary tilt angle to the water flowing in the device is larger with each wall. The chambers created can also be connected through very small openings, so that the reflux is further expanded in time. The central area can be so formed that the air meets through ausgebidete preferred as the nozzle holes on the water surface, with the aim of increasing the Atemgasbefeuchterleistung.

As a kind of very fast and effective way of heating the water, a module is provided, the radiation used for heating. Are conceivable types of radiation of different energy ranges and wavelengths, for example infrared radiation, UV radiation, microwave radiation. Types of radiation are preferably used which have a disinfecting and a heat-effect simultaneously. Particularly preferably, the radiation to small amounts of water can act, so that the water evaporates almost completely by the action of radiation. Thus, a heating and / or disinfection and / or humidifying the ventilation air can be achieved simultaneously.

The actual heating device can be designed as a simple metal plate without electric supply. The energy for the heating of the heater is then fed through contactless eddy current induction.

The water is fed from the water supply through a heated pipe and then into small portions to a vaporization chamber. The advantage is the low required heating power at large thermal dynamics, as only a small amount of water is heated. By suitable arrangement of a check valve, for example, according to the principle of a coffee machine, the water can thus be pumped to a higher level.

An alternative module that allows the heating heat always use only a small amount of water, the floating hot plate. The heating plate is floating just below the water surface and heated primarily the proportion of the water located above the heating plate. especially the amount of water it is thereby heated, which is in contact in humidifying the respiratory gas. In a preferably used module, the floating hot plate may also include a sensor and / or activate. The sensor responds when the water supply is running low and sends a signal to a replenishing and / or activates the refill to a desired water level level. Even at this point, the integrated into the heating plate sensor for switching off the refill of water provides. An addition to the energy savings can be provided by a heat store. By heating the Atemgasbefeuchterbehälters, for example during heat sterilization, cooking or washing in the dishwasher is a permanently installed in the water supply latent heat Pecher, for example by micro-beads of a heat storage material in the wall of the water supply, "charged" with heat energy. While the use of the humidifier, heat is released again and used for heating the water.

A further energy saving is provided by a module which allows heating of the water supply via the device waste heat. The waste heat from the device is used for heating the water. For example, the heat sink of the power supply is at the same heat sink and water heating. In addition, the heat sink with a heater could be tempered to ensure an adjustable water temperature regardless of the equipment load. The water supply is advantageously positioned on the instrument transformer of the ventilator.

For the humidifier also includes modules for generating aerosols can be used. These modules are intended direct delivery of substances such as drugs, fragrance substances, among others in the respiratory tract. The advantage of these add-on modules that the patient his already existing device for administration of breathing gas and humidification of the respiratory gas easy to handle even quickly and safely and not have to buy a second device, which would be required only for the generation of aerosols. Specifically, think of the following modules. a) Druckvernebler: A generated by compressed air nebulized liquid stream through a nozzle. In the continuous use of a Druckverneblers more than half the amount of aerosol during exhalation of the patient generated is lost. By using a circuit breaker on nebulisation may in particular the area of ​​inspiration, preferably, the average inspiration, is limited. This substance is saved. The bandwidth of particles produced by a jet nebulizer and the aerosolized amount per time of an aerosol is dependent on the dimension of the nozzle and the pressure generated by the respiratory gas source, dist. Flow. Therefore source of breathing gas and nebuliser are device-specific coordinate with each other.

b) Ultrasonic: An aerosol is generated by vibration of a piezoelectric crystal, for example. Ultrasonic produce aerosols whose diameter is dependent on the electrically generated oscillation frequency. In particular, this module is constructed such that, in particular are added to the breathing gas flow in the inspiration, preferably to the mean inspiration aerosols.

c) metered dose inhaler: The pressure required for atomization is generated by evaporation. In metered dose inhalers been reached propellants used which were only slowly degraded in the environment to escape and damaged the ozone layer. With the provided herein module and the coupling to a source of breathing gas, it is possible to completely do without propellants. The substance is finely dosed only in the respiratory phases, in particular in the area of ​​inspiration, preferably medium-sized to inspiration added to the respiratory gas stream which allow the patient inhales the greatest possible quantity of substance.

d) Pulververnebler: The present as a fine powder medicament is administered with the inspiratory flow to the patient. The dry powder inhaler requires that the patient can generate an inhalation flow from 25- 60 1 / min. This is not always the case in infants and in adults with severe airway obstruction. The provided here module with the coupling to a source of breathing gas allows the substance finely dosed only in those breathing phases, especially in the area of ​​inspiration, preferably to the central inspiration to add to the flow of breathing gas to allow the patient inhales the greatest possible amount of substance.

e) Vorschaltkammer

In the Vorschaltkammer to beat the fastest and largest, that is not suitable for deposition in the lower airways aerosol particles down. In addition, when using a Vorschaltkammer the patient does not breathe synchronously with the activation of the inhaler, but he can inhale the substance during a few quiet breaths. Characterized the deposition of the substance is reduced in the upper respiratory tract and improves in the lower respiratory tract.

The efficiency of aerosol therapy is improved by reducing the adhesion of substances to the surface of the devices. Such surfaces are used in the modules, which reduce the adhesion of substances to the surface of the devices, such as reducing the electrostatic charge from plastic. Ideally, aerosols, which are used for the treatment of lung diseases, have a diameter between 0, l-10 microns on. Droplets of larger diameter out of the lower airways, smaller particles contain only small amounts of a drug and are also largely exhaled.

The choice of a particular aerosol form has to be done individually. It depends on several factors, not least on the preferences of the patient. For infants and small children, for patients who have the operation of a metered dose inhaler bother ways of generating an aerosol are used which are independent of the cooperation.

Decisive for the compliance of the aerosol therapy are not only technical aspects but also the patient's preference for a specific nebulizer system.

Regardless of the choice of Aerosolverabreichungsart is clear that certain substances can be nebulized only by certain devices for aerosol generation. According to this conditions the appropriate module is selected.

With additional modules for storage of accessory devices are provided which provide the patient with a tailored, practical and simple aid for relief from the daily handling of the inventive devices.

Specifically, required elements, such as hose, mask maintains aufbe- drugs for therapy. Also be either integrated or adapted pm Provided TV and consumer electronics.

Another module for the alarm clock includes an alarm function that takes into account the sleep phases of the patient. By analyzing the sleep hare such phases can be identified for waking preferable to which the patient is not in a deep sleep.

A supplementary module for a measuring time allows calculation of the service life and the Schandauer. This can be determined by a comparison with other device data and environmental data, the typical need for water and energy, which allows appropriate planning and needs-based storage.

the duration of the ventilation, humidification and administration of drugs can be set via a time switching function.

The storage can preferably be carried in or on a drawer, a shelf or on a stand.

The mask is kept preferably such that it is possible for the patient to grab the mask easily and quickly with one hand and to apply. The tube is kept in an orderly and space-saving manner, so that it is easy to grip and to unroll. Preference for this plug-in, clamping or locking devices find use. The attachment is preferably in the range of the device or the bed or on a bedside table or a shelf.

For the hose and the cable of the power supply and a retractable cord is provided. In the drawing embodiments of the invention are shown schematically. Show it:

In several embodiments, the interaction of the modules and the advantages of modular construction will now be described. A sleep apnea patient receives from his doctor a CPAP therapy prescribed to prevent nocturnal breathing interruptions. Following initiation of therapy to the patient's dehydration of the airways, then form infections. The doctor prescribes him a humidifier. The patient chooses the retrofit, modular humidifier according to the invention, since his CPAP machine does not have a humidifier. The humidifier consists of the basic modules required for effective humidification of breathing gas when operating in conjunction with a CPAP device: Water tank lid of the verschießt the water tank filler neck for water in the lid, in particular with a rubber stopper as the closure, supply terminal and breathing hose connection. The perspective view in Fig. 1 shows a breathing gas supply (1) via a connecting element (2) having a supply terminal (3) of a humidifier (4) is connectable. The connecting element (2) is designed nozzle-like manner and also capable of receiving the partially nozzle-like supply terminal (3) or be partially surrounded by it.

The breathing gas supply (1) comprises a display device (5) as well as control elements (6). The breathing gas supply (1) is further provided with a conveying device (7) for the respiratory gas, an electric drive (8) of the

Conveying means (7) and a controller (9) for the electric drive (8) fitted.

The humidifier (4) is provided with a water tank (10), one of a closure element (11) sealable filling opening (12) and a hose connection (13) provided. The hose connection (13) is spigot-shaped, and serves for connecting a beat mung hose. For fixing the respiratory gas humidifier (4) to the breathing gas supply (1) a locking element (14) is provided that can be in the form of a click-lock. Also can be carried out over such a connection coupling of the ventilation tube to the respiratory gas humidifier (4). Above the water tank (10), a flow space (15).

From the illustration in FIG. 1 it is seen that a lateral boundary (16) of the humidifier (4) is designed as an exchangeable facing and here has a contour which is adapted to a contour of the breathing gas supply (1) in the region of a front side. In this way, a very compact overall structure is at a joining of the humidifier (4) and the breathing gas supply (1) is possible. In addition, it can be seen from Fig. 1 in that the humidifier (4) comprises an optional electric connection (17) which is zusammenkoppelbar with a mating terminal (18) of the breathing gas supply (1). This both elements are assembled easily and safely.

likewise, Fig. 1 illustrates that the water tank (10) by a cover (19) to the supply terminal (3) and the hose connection (13) is connected. The filler opening (12) is arranged in the region of the cover (19).

Fig. 2 shows the respiratory gas tube (20) for connection with the hose connection (13). In the illustrated exemplary example an optional pressure measuring line (21) runs adjacent to the respiratory gas tube (20), but in particular is also thought the optional pressure measuring line (21) within the respiratory gas tube (20) to arrange. The respiratory gas tube (20) is an exhalation element (22) having a hose coupling (23) of a breathing mask (24). The breathing mask (24) consists essentially of a Maskengrundkorper (25) and a head cover (26).

Fig. 3 shows a comparison with the embodiment in Fig. 1 modified humidifier (4) in a further perspective representation. It can be seen that the supply connection (3) and the hose connection (13) extending at least partially along a flow tubusför- mig main axis (27). The supply connection (3) and the hose connection (13) with respect to a ground plane (28) of the lid (19) on a raised platform (29) arranged which partially defines the flow space (15). In this way, an increased drain protection is achieved, avoiding overfilling of the water tank (10).

From Fig. 3 also shows that in the region of the hose connection (13) to the cylindrical outer wall of the hose connection (13) is substantially coaxially arranged optional pressure connection (30) for connection to the optional pressure measuring line (21) is provided, which extends in this embodiment within the breathing gas hose (20).

The humidifier according to the invention in this embodiment is suitable in the basic module variant for CPAP respiration pressures up to 18 bar. It is a cold air humidifier without heating the water. When the dealer of the humidifier according to the invention is equipped with that VersorgungsanSchluß- module that allows Konnektierung of the CPAP device of the patient.

From the illustration in Fig. 4 it can be seen that the main flow axis (27) relative to a center line of devices (31) of the humidifier (4) comprises a page offset. Also it can be seen that the optional electrical connection (17) is realized in the illustrated embodiment as a coaxial line arrangement. Basically, it is also possible, however, to use, for example, two juxtaposed pins.

In the illustrated in Fig. 4, the supply terminal (3) with a connecting adapter (32) is provided, which serves for connection to the breathing gas supply (1). The connection adapter (32) is provided with a detent (33) engages the case of a pushing together of the humidifier (4) and the breathing gas supply (1) in a corresponding counter element of the breathing gas supply (1). The lock (33) has an actuating element (34) which cancels the locked state in a manual press, so that the humidifier (4) can be easily separated again from the breathing gas supply (1).

After some time, the patient noticed that the degree of moistening is not enough, and he feels the cold damp air as unpleasant and he leads his frequent colds back to it. The doctor prescribes him a humidifier with heating. According to the prior art the patient would now buy a new device. The humidifier according to the invention is, however, easily be upgraded as needed by adding modules.

Fig. 6 illustrates in a vertical section the structure of the humidifier. From this it can be seen that inside the water tank (10) with the electric terminal (17) connected to the heating element (52) is arranged, which can be realized for example as a heating element, of the stored directly from the water tank (10) liquid is enclosed. Within the supply port (3) flow guiding elements (53) are arranged, which contribute to a uniform flow and avoid turbulence of the flowing respiratory gas.

After some time, the patient's condition deteriorated. The normal CPAP machine no longer breathe loading the patient as needed, sufficient as a chronic obstructive lung disease was found. The doctor prescribes a bi-level ventilator that is capable, by two different pressure levels between inspiration and expiration to ventilate the patient's lungs. The lower pressure value is 6 mbar and the upper pressure value is 30 mbar. As this bilevel device and by a different manufacturer than the CPAP device also the ventilation pressure was significantly increased, the humidifier is no longer suitable. According to the prior art, a completely new humidifier could be purchased. The humidifier according to the invention is, however, adapted by three add-on modules to the new bilevel device. By the higher pressure, another cover with other closure of the filling opening is necessary because these modules CPAP variant were designed for pressures up to 18 mbar. A new supply connection module is needed to connect the humidifier to the bilevel device, as this had a different air outlet connections as the CPAP device. In addition, the new device regulates the basis of measured pressure and / or flow rates of breathing gas, which is why a test lead must also extend through the humidifier through.
