Abstract

A multifunctional, mobile applicator is proposed for connection to a high flow therapy device 1 for nasal insufflation. The applicator has an applicator plug 7 with an additional oxygen connection 13 for a small portable oxygen or therapy air source. When the applicator plug 7 is removed from the high flow therapy device 1, there is an automatic switchover from the no longer available conditioned therapy air from the therapy device 1 to the connected oxygen or therapy air supply, so that the patient can also be nasally insufflated. When the applicator plug 7 is connected to the therapy device 1, the additional oxygen connection 13 is automatically closed. This automatic switchover is achieved by a valve body 24 located in a pressure chamber 21 in the applicator plug 7. Furthermore, the applicator connector 7 optionally has a microprocessor, which has stored patient data and forwards this together with measured data such as volume flow, humidity and temperature to the controller of the high flow therapy device 1 in order to achieve a constant volume flow and a desired humidity and temperature of the therapy air and feed through the patient's nostrils.

Description

State of the art

Nasal insufflation systems for high flow therapy are known, for example from WO 2008/060 295 A2 , Filtered air is sucked in by a blower, compressed, enriched with oxygen, this mixture is misted in a heated humidifier and supplied to the patient by means of an applicator as therapeutic air into the nostrils, if the patient is an adult. For children, an additional mouthpiece is required.

In the case of the nasal insufflation system known from the above publication, the enrichment of the therapeutic air with oxygen is achieved in a high-flow therapy device by means of a microprocessor-controlled valve. The ambient air sucked in and filtered through an air inlet in the High Flow Therapy Unit is thereby selectively mixed with pure oxygen, which is supplied via a separate connection to the High Flow Therapy Unit. In addition to the oxygen content, the microprocessor also controls other parameters of the supplied therapy air, such as gas pressure, gas flow, carbon dioxide content, temperature and humidity. When using the nasal insufflation system, the applicator is directly and permanently connected to the High Flow therapy device.

From the DE 10 2005 000 922 A1 For example, an applicator is known that includes an applicator plug, a lead tube, a y-piece, fork tubes, and a nose piece with prongs. The applicator plug in turn has electrical and pneumatic connector parts. Such an applicator is assumed in the present invention.

In the DE 102 05 955 A1 discloses a method and apparatus for providing respiratory gas, wherein an oxygen generator performs an electrolytic decomposition of water into hydrogen and oxygen and the generated oxygen is compressed in a compressed gas cylinder is fed. The oxygen generator performs both a filling of the compressed gas cylinder and a breathing gas supply for oxygen goggles by means of a control device provided with a distributor, which predetermines a forwarding of the respiratory gas in the direction of the oxygen goggles and / or in the direction of the compressed gas cylinder in response to respective control specifications. It is also disclosed that a patient can optionally make a connection via a consumption control as a connection element to an oxygen generator or to a compressed gas cylinder. To provide a patient with a relatively large range of motion in his home or other lounge, a longer oxygen tube connection hose is suggested.

From the DE 38 349 A is a respiratory device for penetrating into rooms with non-breathable atmosphere known, via an adjustable by a hand lever three-way valve, the air supply from a fixed, entrained oxygen tank can be switched on or off to the respiratory organ and at the same time a hose over which otherwise an outside air supply is made, abrespektive is coupled, which is done by a attached to the chick of the three-way cock coupling part.

A ventilation system, especially for hospitals, for carrying out CPAP or oxygen therapies is known from US Pat US 6,158,430 A known. This consists of one or more portable ventilation devices that are operable by means of associated interfaces at docking stations located at different locations or stations. The docking stations are in turn connected to a central gas supply to the hospital to provide the oxygen supply to the ventilation equipment. In addition, individual gas cylinders can be directly connected to a docking station.

From the WO 2013/089714 A1 A hybrid self-rescue equipment is known that allows people to move in adverse environments, such as mines, tunnels, or contaminated air tanks. For this purpose, all necessary components such as breathing tube, mouthpiece, breathing mask, nose clips, safety glasses, etc. are housed in a portable housing. Furthermore, the self-rescue equipment has a valve housing with multiple ports to which either breathing air hoses or dust filters can be connected.

Since applicators, as z. B. from the DE 10 2005 000 922 A1 are known to always have to be connected to the supply of patients with the high flow therapy device and the high flow therapy device due to its physical size and mass is not transportable, the patient is bound to the high flow therapy device and thus immobile. Also, the supply hose can not be made arbitrarily long to give the patient some movement, because the parameters of the supplied therapeutic air, especially the flow and pressure properties, can not be secured to the nose piece with the set parameters as generated by the High Flow therapy device because these parameters are on their way from the high flow therapy device to the nose piece due to external influences change.

The lack of mobility of the patient is a considerable disadvantage. The patient is not able to perform short distances without gas supply and thus breathing assistance.

Underlying problem and solution

To overcome this deficiency, while achieving maximum mobility and flexibility and continue to allow a supply of oxygen or therapeutic air, the present invention as an object. This object is achieved by a multifunctional, mobile deployable applicator according to the present claim 1. Further advantages of the invention indicate the features of the subclaims.

Achieved benefits

The multifunctional, mobile deployable applicator with its advantageous design of the applicator plug enables on the one hand the continuous supply of the conditioned therapy air (TNI) provided by the High Flow therapy device and on the other hand ensures the supply of oxygen (LTOT) or therapy air if the patient removes the applicator plug from the high Flow therapy device decreases, for example, to go to the toilet, kitchen, etc., with automatic switching.

In these aisles, the patient is supplied by an easy-to-handle portable oxygen or therapy air source and thus, the oxygen or therapy air support is continuously ensured. This is a significant gain in quality of life for the patient, he does not need to fear a decrease or failure of his respiratory support and is therefore protected from a possible life-threatening condition.

In addition, the patient should be supplied with plugged applicator in each of his nostrils with a constant volume flow of the therapeutic air, as only so the dead space is flushed out reliably. For this purpose, the parameters of the therapy air are measured close to the patient and these are primarily regulated in the high-flow therapy device so that the volume flow is kept constant at the outlet openings of the nasal prongs. This is achieved by advantageous, explained in more detail in the description measures.

The design of the valve body as a ball according to claim 2 allows a simple structure with the valve seats and their seals to ensure the valve function.

If, however, the valve body designed as a cylinder piston, as claimed in claim 3, the usual in this embodiment advantages such. B. better and lighter seals achieved.

Since the electronic components located in the applicator must be supplied with energy, according to claim 4 contacts for a power supply and / or signal and data lines already exist in the applicator and there are no additional external connection lines needed.

According to claim 5, a functional unit is advantageously incorporated in the Y-piece, which has a directional control valve (claim 6), transmitter and receiver (claim 7) and an electronic processing unit (claim 8). These components are supplied in a simple manner via heating wires in the supply hose or batteries or rechargeable batteries with energy, as the alternative features in claim 9 show.

The Applikatorstecker itself can be equipped according to claim 10 with a programmable microprocessor and its memory according to claim 11 patient data and parameter information of each individually required therapy air and service data contains, which are needed for the evaluation by the control function in High Flow therapy device. When replacing the therapy devices, the patient can thus be supplied without any new settings on the device with a consistent, associated therapy air, since the setting values can be taken over by the applicator plug.

In order to be able to react more individually to anatomical asymmetries, the Y-piece is arranged no closer than 5 mm from the tines, as laid down in claim 12.

The claimed in claim 13 use of antibacterial coated materials protects the patient from infection.

It is also advantageous, as can be seen from claim 14, that therapy air can also be supplied to the oxygen connection instead of oxygen.

9 Details of the functional unit

1 shows a nasal insufflation system consisting of a high flow therapy device 1 and an applicator 6 According to the state of the art. On the high flow therapy device 1 are the inlet for the ambient air 2 , the connection for the oxygen supply 3 , the operating and display device 4 and at the exit for the therapy air the connection 5 for the applicator 6 recognizable. The applicator 6 basically consists of at least one applicator plug 7 , a supply hose 8th , a Y-piece 9 , Fork hoses 10 and a nose piece 11 with prongs 12 ,

The inventive multifunctional, mobile applicator applicator 6 is with an applicator plug 7 equipped, the, how 2 shows on the high flow therapy device 1 attachable and has an oxygen connection 13 and a therapy air connection 14 for the supply hose, not shown in this figure 8th , The applicator plug 7 consists of at least one upper part 15 and a bottom part 16 ,

3 shows the top 15 of the applicator connector 7 from below in partial view with a humidifier interface 17 through which the applicator plug 7 with conditioned therapy air from the High Flow therapy device 1 is supplied. Also shown is a lower valve seat 23 with his seal 22 and about a valve body 24 who is in a leadership 27 is linearly movable. This is in a pressure chamber 21 arranged. Next to it are contacts 18 / 19 for the power supply and for signal and / or data lines.

A vertical cut through the applicator connector 7 . 4 , shows off his top 15 and bottom part 16 existing housing 20 with the pressure chamber 21 into the bottom of the high flow therapy device 1 via the humidifier interface 17 Therapeutic air can flow. This humidifier interface 17 has at its upper end with the seal 22 equipped lower valve seat 23 on which the valve body 24 (eg, as here a ball or a cylindrical valve piston) rests when the applicator plug 7 not on the High Flow therapy device 1 sitting. Above the valve body 24 there is another, also with a seal 22 equipped upper valve seat 25 that connects to the oxygen port 13 can produce. Also is a helical compression spring 26 visible, which with their spring force on the valve body 24 and thus affects this on the seal 22 of the lower valve seat 23 the humidifier interface 17 suppressed. So, when the applicator plug 7 from the high flow therapy device 1 is removed, the humidifier interface 17 reliably sealed.

The valve body 24 is when the application plug 7 on the High Flow therapy device 1 by means of latching or locking firmly seated by an attached thereto fixed actuator 28 , as 5 shows, up against the seal 22 of the upper valve seat 25 pressed. Thus, no oxygen can pass through the oxygen port 13 in the pressure chamber 21 flow. This ensures that the high flow therapy device 1 provided therapy air into the pressure chamber 21 into and beyond the therapy air connection, which can not be represented here in this sectional plane 14 to the supply hose 8th flows. This flow path is the rule.

A vertical cut through the applicator connector 7 multifunctional, mobile applicator 6 in the level of the therapeutic air connection 14 for the, not shown here, supply hose 8th , shows 6 , This therapy air connection 14 represents the connection of the pressure chamber 21 with the supply hose 8th ago. This connection is with attached, firmly locked or locked applicator connector 7 on the High Flow therapy device 1 always open because the actuator 28 the valve body 24 from the, in 5 shown, seal 22 of the valve seat 23 lifts off and the pressure chamber 21 then always supplied with therapeutic air.

If the patient wishes to be mobile for a predictable period of time, then the portable oxygen cylinder, monitored for its degree of filling, will be connected to the oxygen supply at the latest 13 if not already done. Will the applicator plug 7 now from the high flow therapy device 1 removed, the actuator acts 28 no longer on the valve body 24 , By the Force of the helical compression spring 26 becomes the valve body 24 on the seal 22 of the lower valve seat 23 pressed and closes this. Oxygen then flows through the oxygen port 13 in the pressure chamber 21 on to the therapy air connection 14 in the supply hose 8th to get. For the patient is the multifunctional, mobile applicator 6 with a small, easy-to-use oxygen or therapeutic air source without effort and comfortable to handle in his movement and allows only thereby the mobile movement possibility while maintaining this oxygen or therapeutic air supply without the High Flow therapy device 1 , The uninterrupted supply of oxygen or therapeutic air is thus reliably ensured during the movement, which is not possible without the valve assembly according to the invention described above and its function.

The view of the applicator plug 7 from below (plug-in side to high flow device) in 7 shows next to the humidifier interface 17 because of the valve body 24 not shown here, the helical compression spring 26 as well as the contacts 18 and 19 for the power supply and / or the signal and / or data lines (eg for data line 32 . 8th ). These contacts correspond to corresponding contacts of the High Flow therapy device 1 ,

In addition to the function of mobile operational capability allows the inventive multifunctional, mobile operational applicator 6 still monitoring functions (such as usage time, temperature, service intervals, etc.), as they are in terms of 8th and 9 be described in more detail.

If necessary, the Y-piece 9 , which passes the therapy air, with a functional unit 29 be equipped, like 8th shows. This functional unit 29 contains sensors 33 ( 9 ), which z. B. volume flow, humidity, temperature, etc. measure. The measured data are transmitted by means of a data line 32 in the supply hose 8th to the applicator connector 7 and continue through the contacts 19 to the high flow therapy device 1 given. Alternative to the data line 32 has the functional unit 29 via transmitter and receiver for data transmission or transmits this data directly via the heating cable. These transmitters and receivers communicate with the corresponding receiver and transmitter either in the applicator connector 7 or in the High Flow therapy device 1 , When transmitter and receiver are in the applicator connector 7 built-in, the data are stored by means of the contacts 19 the high flow therapy device 1 forwarded so that this can optimize the parameters of the therapy air. The power supply of the transmitter and receiver in the functional unit 29 Can be done by batteries or rechargeable batteries. Also possible is the power supply by means of the supply hose 8th extending heating wires 31 , which transmit the necessary energy. Also, the batteries can by means of the heating wires 31 be loaded (see enlarged section in 8th ).

To perform these functions, the functional unit has 29 , as 9 shows, via sensors 33 for measuring the parameters of the passing therapeutic air and an electronic processing unit 34 which passes on the measured data.

In addition to the aforementioned sensors 33 can in the functional unit 29 a directional valve 30 be provided, which differentiates the therapy air to the fork tubes 10 passes. This is about the fork tubes 10 alternatively as a function of suitable sensors in the area of the tines 12 at the outlet openings of the constant volume flow ensured. The different resistance of the patient's airways through the nostrils is thus taken into account.

The applicator plug 7 may further comprise a programmable microprocessor, in which service data, the data and parameters of the patient, the multifunctional, mobile deployable applicator 6 used, are stored. This data can be used for the individual control of the High Flow therapy device 1 be necessary, because the correct conditioning of the therapy air can be adjusted. The patient changes with his multifunctional, mobile applicator 6 the previously used High Flow therapy device 1 , so this automatically turns around and the patient immediately receives a conditioned therapy air with the necessary and defined parameters for him, so he is in this regard of the selected high flow therapy device 1 independently. This assumes that the high flow therapy device 1 In turn, it has a corresponding control which the data from the microprocessor in the application plug 7 can handle.

The data of the patient include, for example, the applicator-specific properties, such as flow limitation in a child applicator, identification of the applicator type, operating hours and running times, etc.

Alternative to the directional valve 30 in the functional unit 29 can be in the nose piece 11 between the tines 12 a controlled directional control valve are located to the volume flow at the respective outlet openings of the tines 12 to keep constant. This activation takes place with the same technical solution as in the functional unit 29 , Also, the outlet cross sections of the tines 12 be formed asymmetrically. Thus, furthermore, different cross-sectional areas and / or cross-sectional shapes of the outlet openings of the tines are 12 conceivable in the nostril.

The aim of all measures described above is at the respective outlet openings of the tines 12 to provide a constant volume flow taking into account all necessary parameters.
