Definitions

  • the invention relates to a device for gas supply in sleep apnea with a respiratory gas source, which leads to at least one breathing opening of a patient via a flow guide, the flow guide being connected to a gas humidifier in order to dispense a liquid stored in a liquid reservoir in partial quantities to the breathing gas to be supplied .
  • Various devices are already known to prevent the trachea from sagging during sleep in apnea patients, which leads to unconscious shortness of breath.
  • face masks are known that are placed on the nose area of the patient. The patient is supplied with small amounts of breathing air via this face mask and a blower connected to the face mask via an air hose. This creates an overpressure in the patient's nose area, which causes the patient's trachea to be forced open and, as a result, an unconscious shortness of breath to be prevented.
  • the patient's mucous membranes can dry out, which can lead to pain or nosebleeds.
  • devices have been created in which humidifiers are arranged in front of the air lines leading to the face mask.
  • a disadvantage of these previously known devices is that the humidifier must always be used, otherwise the breathing gas line in the device is interrupted.
  • the humidifier is not always essential. If the air humidity is already high, for example in summer, additional humidification of the breathing air is perceived as disruptive by many patients. In addition, the humidifier places high demands on hygiene, which require considerable additional effort when the humidifier is used continuously. Since the humidifier has a heating device with which a water supply is gradually evaporated, a humidifier that is permanently used results in high power consumption.
  • the flow guidance of the device has at least two preselectable flow paths, of which a first flow path leads to the patient's breathing opening bypassing the gas humidifier and of which a second flow path leads to the patient's breathing opening via a mixing point, which mixing point communicates with the gas humidifier.
  • the breathing gas can be conducted via the first flow path.
  • the device can also be used without the gas humidifier and the patient can be supplied with non-humidified breathing gas.
  • the breathing gas can optionally also be conducted via the second flow path, the breathing gas being humidified at the admixing point and this humidified breathing gas being supplied to the patient.
  • the two flow paths can be arranged in different ways.
  • two separate gas lines can originate from the respiratory gas source, the first of which is led directly to a respiratory gas outlet and the second of which is connected to the gas humidifier.
  • Another breathing gas line then leads from the gas humidifier to the breathing gas outlet.
  • a flow path starts from both respiratory gas sources, which flow into one another before a common respiratory gas outlet. Another possibility is to design the second flow path as a bypass to be described later.
  • the gas humidifier has a liquid container as a liquid reservoir, which liquid container can be removed and reinserted in a humidifier and / or device housing.
  • the liquid container can then be removed from the device and easily cleaned, which considerably simplifies the handling of the device with regard to hygienic aspects.
  • valve arrangement with mutual positive control is provided in the flow paths of the flow guide.
  • the flow path that is not required is closed while the other flow path is open.
  • the forced control ensures that only one of the flow paths is open at a time.
  • valve arrangement is in control connection with a control device for switching the valve arrangement on the one hand when the liquid container is removed into the first flow path and on the other hand when the liquid container is inserted into the second flow path.
  • the valve arrangement is automatically second flow path is opened so that the breathing gas is passed through the admixing point, while when the liquid container is removed, this second flow path is closed and the first flow path is open bypassing the gas humidifier.
  • a manual switching of the valve arrangement when removing or reinserting the liquid container is not necessary. Accidental guiding of the breathing gas via the wrong flow path, for example when the liquid container is removed, is thus prevented via the second flow path.
  • the gas humidifier is connected to the flow guide via a bypass, which bypass can be blocked on the inlet and / or outlet side.
  • the second flow path is then formed by this by-pass.
  • the by-pass branches off from the first flow path on the inlet side and leads to an inlet of the gas humidifier, while the by-pass leads away from the gas humidifier on the outlet side and flows back into the first flow path.
  • the bypass can be blocked on the inlet and / or outlet side, so that the breathing gas, when it is routed via the first flow path, cannot undesirably evade via the bypass.
  • the bypass should be lockable on the entry and / or exit side.
  • blocking the bypass on both sides can be expedient in order to prevent breathing gas from escaping at the bypass on the inlet or outlet side.
  • a main flow shut-off valve which is interposed in the flow direction behind the by-pass inlet and before the by-pass outlet in the flow guide and that with at least one in the bypass pass inlet and / or bypass outlet interposed bypass check valve can be alternately opened and closed.
  • the breathing gas can flow through the gas humidifier via the bypass when the bypass shut-off valves are open, while the first flow path is interrupted bypassing the gas humidifier through the main flow shut-off valve. If, on the other hand, the first flow path is opened by opening the main flow shut-off valve, the secondary flow shut-off valve (s) are automatically closed and the by-pass is interrupted so that breathing gas can no longer get through the gas humidifier.
  • check valves are designed as valve spools, which are preferably mechanically positively controlled with one another.
  • the valve arrangement can be used with these
  • shut-off valves for actuation are in control connection with the moisture container inserted into or removed from the humidifier and / or device housing, and that the shut-off valves are preferably drive-coupled for this purpose with at least one button which can be acted upon by the liquid tank.
  • the main flow valve can be moved into its closed position against a restoring force and the secondary flow shut-off valve (s) can be moved into its (its) open position against a restoring force.
  • the button is actuated and the first flow path is closed, while the second flow path to the admixing point is opened.
  • the main flow shut-off valve automatically moves to its open position, thus opening the first flow path bypassing the gas humidifier.
  • the bypass shut-off valve (s) is (are) moved into their closed position and the second flow path is thus closed.
  • the breathable gas can each only propagate over one of the flow paths and with the insertion or removal of the liquid 'container, the respective flow path is predetermined.
  • a further embodiment provides that the main flow shut-off valve is displaceably guided transversely to the main flow direction and approximately parallel to the direction of insertion of the liquid container in the device housing, and that the valve slide of the main flow shut-off valve is displaceable against a restoring force in the direction of insertion of the liquid container and is in drive connection with the liquid container .

  • valve arrangement can be implemented with little design effort. This applies to both the forced coupling of the main flow shut-off valve and the secondary flow shut-off valve (s) as well as the Forced operation of the valves when inserting or removing the liquid container.
  • the gas humidifier for steam generation has a heating device arranged in the area of the liquid container, which is electrically connected to a spring-loaded electrical switch button, which switch button is acted upon by the liquid container in its position of use in the container and / or device housing, and is in its operating position.
  • the circuit of the heating device is automatically closed in this area, so that steam for humidifying the breathing gas can be formed in the gas humidifier.
  • the heating device is automatically switched off by the spring load of the electrical switch button, thereby avoiding unnecessary power consumption.
  • liquid level in the liquid container is limited by means of an overflow and if the container inlet and outlet that can be connected to the bypass are preferably arranged at a distance above the maximum liquid level. This ensures that the breathing gas led through the gas humidifier only connects with water vapor and that no water drops are entrained into the breathing gas lines.

  • a device for gas supply in sleep apnea designated as a whole by 1, has a breathing gas source 2, which leads to a breathing gas outlet 4 via a flow guide 3.
  • the breathing gas source 2 is formed in the figures by a blower with which the ambient air surrounding the device is conveyed into the flow guide 3.
  • the breathing gas source could, however, also be, for example, a pump or a gas bottle, which releases the pressurized gas contained therein via a valve into the flow guide 3.
  • An air hose (not shown in more detail) can be connected to the breathing gas outlet 4, which connects the device 1 with a face mask (also not shown) that extends to the face A patient's nose area can be connected.
  • the flow guide 3 is connected to a gas humidifier 5 and has two flow paths 6a, 6b. Bypassing the gas humidifier 5, the first flow path 6a leads to the breathing gas outlet 4 and the second flow path 6b leads to the breathing gas outlet 4 via an admixing point 7 to be explained in more detail, which is connected to the gas humidifier 5.

  • the main flow shut-off valve 11 is displaceably guided transversely to the main flow direction and parallel to the direction of insertion (arrow E) of the liquid container 9.
  • the main flow shutoff valve 11 has a ramp 16. This run-up slope 16 interacts with an actuating end face 17 of the valve slide 13, which is displaceably guided transversely to the direction of movement of the main flow shut-off valve 11. This results in a forced coupling of the main flow shutoff valve 11 and the secondary flow shutoff valves 12.

  • a level limit is provided in the liquid container 9. This is formed by an outlet connection 20 arranged on the bottom 19 of the liquid container 9. If the liquid container 9 is filled too strongly, this excess liquid is discharged from the gas humidifier 5 via the outlet connection 20 and a discharge line 21. The maximum fill level is thus determined by the height h of the drain connector 20.
  • the container inlet 22 and the container outlet 23 of the liquid container 9 are each arranged at a distance above the maximum liquid level.
