Abstract

Respiratory phase controller for the control of the O2 supply via pressure changes during the breathing operation for an oxygen apparatus equipped with a pressure controller, a quantity controller and a nasal tube for medical therapy, comprising a low-pressure box with a membrane having a connecting nozzle for the nasal tube and connected on the other side with a switching contact for transformation of a pneumatic signal into an electrical signal, whose lines lead to a two-way solenoid valve which is known per se and which can be connected on the input side via a connecting nozzle for the pressure controller of the oxygen apparatus and on the output side via a similar connecting nozzle for the quantity controller, and a bypass line having one connection each for the quantity controller and for the nasal tube of the oxygen apparatus. <IMAGE>

Description

temthasenrelertemthasenreler

Die erfindung betrifft einen Atemphasenregler zur Steuerung der 02-Abgabe für ein für medizinische Theraple vorgesehenes Sauerstoffgerät gemäß Oberbegriff des Anspruches 1 Es ist bekannt , zur Stimulierung des 02-Wechsels bei Altersbeschwerden und für Regenerationskuren als Prophylaktikum Sauerstoffgeräte mit Druck- und Mengenreglern und inhalierbrillen wie Nasensonden einzusetzen. In dieser usstattung tritt während des Betriebes, unabhängig von den Atemphasen des Patienten, Sauerstoff über die Nasensonde as, d.h. in den Atempausen geht Sauerstoff verloren. Bei medizinischen 3eatmungsgeräten und auch bei Tauchgeräten wird der Sauerstoffstrom über relativ aufwendige apparaturen automatisch gesteuert. Bei diesen Geräten. von denen erstere im allgemeinen ambulant eingesetzt werden 9 existieren noch keine Vorrichtungen, die den Sauerstoffstrom während der Atempausen bzw. in der @usatmungsphase unterbrechen.The invention relates to a breathing phase regulator for controlling the O2 delivery for an oxygen device intended for medical therapies according to the preamble of claim 1 It is known to stimulate the O2 change in old age complaints and for regeneration cures as prophylactic oxygen devices with pressure and volume regulators and use inhalation goggles like nasogastric tubes. In this equipment occurs during of the operation, regardless of the patient's breathing phases, oxygen via the Nasal tube as, i.e. oxygen is lost during breathing pauses. With medical 3breathing equipment and diving equipment, the flow of oxygen is relative complex equipment is controlled automatically. With these devices. of which the former are generally used on an outpatient basis 9 no devices exist yet, which interrupt the flow of oxygen during pauses in breathing or in the breathing phase.

s bestand daher die Aufgabe, für ein medizinisches Sauerstoffgerät über die Druckänderungen, die beim Atmungsvorgsng auftreten, einen Regler zu kreieren, der den Sauerstoffverbrauch auf die Phase des Einatmens, d.h. die aktive Phase beschränkt. Gelöst wurde diese Aufgabe durch einen Atemphasenregler gemäß dem Hauptanspruch. Nähere Details werden in der Beschreibung ausführlich widergegeben.The task was therefore for a medical oxygen device to create a regulator via the pressure changes that occur during breathing, which limits oxygen consumption to the inhalation phase, i.e. the active phase. This task was solved by one Respiratory phase regulator according to the Main claim. Further details are given in detail in the description.

Erläutert wird die Erfindung an Hand einer Zeichnung.The invention is explained using a drawing.

So zeigt denn Figur t den schematischen Aufbau des neuerungsgemäßen Atemphasenreglers.So then Figure t shows the schematic structure of the innovation Respiratory phase regulator.

Zur Steuerung eines Sauerstoffgerätes mit Druck- und Mengenregler und Nasensonde, das nicht dargestellt ist, wird in einer Druckdose, die eine Membran enthält, sowohl der beim Einatmen auftretende Unterdruck als auch der beim Ausatmen entstehende Druck genützt.For controlling an oxygen device with pressure and volume regulator and nasogastric tube, which is not shown, is in a pressurized can which has a membrane contains both the negative pressure that occurs during inhalation and that during exhalation resulting pressure used.

Der erfindungsgemäße Atemphasenregler, der. in einem Gehäuse untergebracht ist, enthalt eine Druckdose 1 mit einer membran 2, die einen Anschlußstutzten 3 zur Leitung der Nasensonde besitzt. Verbunden ist die Druckdose ferner mit den Schaitkontakten 4a und 4b, die über Leitungen 6, 6a zu einem an sich bekannten 2-Wege-Magnetventil 5 führen und zur Umwandlung eines pneumatischen Signals in ein elektrisches dienen. Beim Einatmen entsteht in der Leitung der Nasensonde ein Unterdruck, der über den Anschlußstutzten auf die Membran übertragen wird. Durch diesen Vorgang werden die Kontakte 4a und 4b des Schalters geschlossen, und über die Bettung 6 wird das 2-Wege-Magnetventil geöffnet. Dieses Miagnetventil verfügt über je einen Anschluß an das Sauerstoffgerät, über einen an der Eingangsseite 7 und einen an der Ausgangsseite 8. Die Leitung 7a führt zum Druckregler und die Leitung 8a zum iiengenregler des Sauerstoffgerätes. Im Regler ist desweiteren eine Bypassleitung 9 eingebaut, die den Mengenregler und die Nasensonde miteinander koppelt. Dadurch werden die sonst erforderlichen Schlauchverbindungen auf ein mindestmaß beschränkt. Bei geöffnetem Magnetventil kann also der Sauerstoff über die Nasensonde austreten.The breathing phase regulator according to the invention, the. housed in a housing is, contains a pressure cell 1 with a membrane 2, which has a connecting piece 3 to conduct the nasogastric tube. The pressure cell is also connected to the switch contacts 4a and 4b, via lines 6, 6a to a known 2-way solenoid valve 5 and serve to convert a pneumatic signal into an electrical one. When you breathe in, a negative pressure is created in the tube of the nasogastric tube, which is above the Connection stub is transferred to the membrane. Through this process, the Contacts 4a and 4b of the switch are closed, and the 2-way solenoid valve is activated via the bedding 6 opened. This solenoid valve has a connection to the oxygen device, via one on the input side 7 and one on the output side 8. The line 7a leads to the pressure regulator and the line 8a to the volume regulator of the oxygen device. In addition, a bypass line 9 is built into the regulator, which the flow regulator and couples the nasogastric tube together. This eliminates the otherwise required hose connections limited to a minimum. When the solenoid valve is open, the oxygen can exit through the nasogastric tube.

Analog dazu wird beim Ausatmen durch den entstehenden Ueberdruck in der Membrandose der Schaltkontakt getrennt, das Magnetventil geschlossen und somit die Sauerstoffzufuhr unterbrochen.Similarly, when you exhale, the excess pressure in the diaphragm box, the switching contact is disconnected, the solenoid valve is closed and thus the oxygen supply interrupted.

lit dieser Regelung wird erreicht, daß exakt nur bei der Einatmungsphase, sogar bei sich ändernder Atmungsfrequenz, die Atemluft mit Sauerstoff angereichert wird.With this regulation it is achieved that exactly only during the inhalation phase, Even when the breathing frequency changes, the breathing air is enriched with oxygen will.

Ein weIterer Vorteil besteht darin, daß sich die Funktionsweise des Atemphasenreglers durch eine Anzeigevorrichtung optisch überwachen läßt Dazu ist eine Leuchtdiode 10 mit der , Versorgungsspannung, die den Betriebszustand kennzeichnet, parallel geschaltet Eine zweite Leuchtdiode 11 t Eit dev @agnetventil parallel geschaltet und zeigt rerl signalzustand, d.h. die Einatmungsphase an. Alle Anußstutzen 3, 7a, 8a, 9a, 9b können an einer Frontpratte 12 des Reglergehäuses angebracht werden, wodurch der Regler eine kompakte Art in Ausführung und Gestaltung erfährt. Der Regler läßt sich in einfacher Weise über einen Zagneten an der Flasche des Sauerstoffgerätes befestigenAnother advantage is that the functionality of the Respiratory phase regulator can be visually monitored by a display device a light emitting diode 10 with the, supply voltage, which characterizes the operating state, connected in parallel A second light emitting diode 11 is connected in parallel to the dev @ solenoid valve and shows the signal status, i.e. the inhalation phase. All lugs 3, 7a, 8a, 9a, 9b can be attached to a front plate 12 of the controller housing, whereby the controller experiences a compact type in terms of design and design. The regulator can be easily done using a magnet on the bottle of the oxygen device attach
