Definitions

  • the invention relates to a device for filling containers with oxygen-enriched breathing air for use in medical oxygen therapy.
  • oxygen enrichment devices or oxygen concentrators which enrich the oxygen in the ambient air with relatively low power and release a breathing air which is highly enriched with oxygen.
  • the capacity of these devices is designed to meet the needs of one or fewer patients during the treatment, which is normally also sufficient.
  • the patient is connected to the device via hose lines during the treatment and must visit a doctor's office to use the multi-step process. So that the patient can continue the oxygen therapy independently at home, an oxygen container is therefore left to him for the oxygen supply, which contains at least the amount of enriched breathing air required for the intended application.
  • the oxygen tank is filled from oxygen bottles, which are delivered filled by the relevant suppliers.
  • the invention is based on the object of specifying a device of the type mentioned at the outset which enables or simplifies the filling of the oxygen containers in the practices themselves and makes them more economical.
  • a compressor for compressing the oxygen-enriched breathing air is connected to an oxygen enrichment device and that the outlet of the compressor is connected to at least one oxygen tank to be filled.
  • a particularly useful and advantageous embodiment of the device according to the invention results from the fact that a plurality of oxygen containers to be filled are connected to the outlet of the compressor via at least one valve and that actuating means are provided which interrupt the valve or the valves from the connection to the oxygen containers Switch blocking positions one after the other into consecutive oxygen tanks with filling positions connecting the outlet of the compressor.
  • the device designed in this way makes it possible to automatically fill several oxygen containers with enriched breathing air one after the other.
  • a further embodiment of the invention is that at the outlet of the Uer - dichters over several series-connected valves are connected to be filled several oxygen container and that are provided for the valves one after the other in the filling switching actuating means.
  • the invention further provides that at least one pressure monitoring means is provided for monitoring the pressure in the respective oxygen container during the filling process and that a control arrangement connected to the pressure monitoring means and to the actuating means of the valves is provided for switching on of the valve or the valves in the next filling position for filling the next oxygen tank as soon as the pressure in the oxygen tank concerned reaches a predetermined value during the filling process.
  • a display device connected to the control arrangement shows the filling state of the connected oxygen containers. In this way it is easy to determine how far the filling process has progressed is.
  • the storage containers can be a storage medium, e.g. a zeolite.
  • a storage medium e.g. a zeolite.
  • the storage containers can be freely movable gas bottles or they can be accommodated in a separate storage device, the housing of which can advantageously be identical to that of the basic device.
  • the device proposed according to the invention has the advantage that oxygen containers for the use of oxygen therapy in medical practices can be filled in a simple and economical manner with oxygen-enriched breathing air.
  • the operation of the device is very economical because the enrichment device can be used during treatment breaks or overnight to fill the oxygen tank. In this way, an enrichment device with a relatively small capacity is sufficient to fill the oxygen container, which is normally designed for use in medical practices.
  • the handling of the device according to the invention is simple and can also be carried out by technically not trained practical personnel.
  • FIGS. 1 and 2 denotes an oxygen enrichment device which enriches the oxygen in the ambient air and releases a breathing air which is highly enriched with oxygen.
  • This device contains in a housing 19 (see FIG. 2) two compressors 22 and 22a and two zeolite containers 21 and 21a.
  • a collecting container 23 is provided for the oxygen-enriched breathing air.
  • the device works according to the known pressure change method, in which ambient air is forced through one of the zeolite containers into the collecting container 23 with a compressor, while the zeolite regenerates in the other container. This process is not the subject of this invention and therefore requires no further explanation at this point.
  • the oxygen enrichment device 1 which in the embodiment shown in FIG. 2 is designed as a basic device, can be moved on rollers 24. On its front side it has a switch arrangement 26 for monitoring and setting the process sequence.
  • the oxygen content in the air can be enriched up to 90% and above.
  • a valve 13 is connected to the outlet of the oxygen enrichment device 1, that is to the collecting container 23, which can be adjusted by hand as required, so that the enriched breathing air removed from the collecting container is either filled into bottles 4a-4c or directly via a breathing device 18 can be used for oxygen therapy.
  • the housing 19 In order to be able to take off highly oxygen-enriched air directly from the collecting container 23 for oxygen therapy, there is a removal on the front side of the housing 19 insert 27 with a plug connection 28 for the connecting hose of the breathing apparatus 18, a breathing mask, oxygen goggles or the like. Provided (see FIG. 2).
  • the enriched breathing air is removed from the collecting container 23 via a breathing air humidifier in the form of a water bottle 29.
  • the amount of breathing air removed is measured with a flow meter 16 and displayed with an indicator 17.
  • the flow rate to the breathing apparatus 18 can be adjusted with a flow rate controller 14.
  • the device 1 thus allows the direct use of oxygen therapy.
  • a compressor 2 is connected to the outlet of the collecting container 23, which compresses the enriched breathing air and delivers it via valves 3a, b and c to the oxygen container 4a, b and c.
  • the valves 3a, b and c are connected in series at the outlet of the compressor 2. They are designed as two-way valves, which close the connections 6a, b and c of the oxygen tanks 4a, b and c in the blocking position and connect the connections 6a, b and c to the outlet of the compressor 2 in their filling position.
  • the valves 3a and 3c are in their blocking position, in which a connection between the outlet of the compressor 2 and the relevant oxygen tank 4a or 4c is not possible.
  • the valve 3b is in Filling position, in which the outlet of the compressor 2 is connected to the connection 6b of the oxygen tank 4b, so that the oxygen tank 4b is filled.
  • actuating means 7a, b and c are provided in the form of pneumatic or hydraulic cylinders or electromagnetic actuators which are controlled by a control arrangement 8.
  • the pressure at the outlet of the compressor 2 and in the line to the oxygen tank 4a, b or c to be filled is monitored with a pressure monitoring means 9, for example a pressure-voltage converter, the output of which is connected to the control arrangement 8.
  • a safety valve can be assigned to the pressure monitoring means 9, which prevents overloading of the pressure lines and the oxygen containers.
  • a pressure setpoint can be specified in a setpoint generator 11, which is also connected to the control arrangement 8.
  • the control arrangement 8 blocks the filling means for filling an oxygen container via the actuating means 7a, b or c in question located valve 3a, b or c and opens the next valve associated with a previously not filled oxygen tank.
  • the predetermined pressure is in the oxygen container 4b
  • the valve 3b is closed, while the valve 3c is opened, so that then the oxygen tank 4c is connected to the outlet of the compressor 2 and filled N so on reaching ird .
  • the already filled oxygen containers 4a and 4b can be used to empty them Oxygen tanks are replaced so that the filling process can be continued there.
  • a display device 12 is connected to the control arrangement 8, which indicates the filling state of the oxygen tanks 4a, 4b and 4c connected to the device, so that it can be seen at a glance which oxygen tanks have already been filled are and can be exchanged for empty ones.
  • the oxygen containers 4a-c can be accommodated in storage devices 33, the housings of which are identical to the housing 19 of the basic device and which, like the basic device, can be moved on rollers.
  • a storage medium e.g. a zeolite.
