Definitions

  • CPAP device Continuous positive airway pressure generating device
  • the present invention generally relates to a device for producing a continuous positive
  • Airway pressure or CPAP device for short and in particular a nasal CPAP device or nCPAP device for short.
  • CPAP or nCPAP devices The principle of these CPAP or nCPAP devices is that the patient breathes against a pressure that is higher than atmospheric pressure, which facilitates and improves spontaneous breathing in certain cases of impaired pulmonary function.
  • DE-C-3 119 814 discloses a CPAP or nCPAP device with a breathing channel which opens to the atmosphere at its free end and which at its other end has a coupling piece for attachment to the nose and / or can be provided in the patient's mouth, and with an inlet duct for fresh gas, which is connected to the respiratory duct at a point between its ends and whose flow rate is adjustable.
  • EP 0 447 443 B1 discloses a development of this known CPAP or nCPAP device, the breathing channel having a first branch channel that can be connected to the coupling piece and a second branch channel that is open to the atmosphere.
  • the two breathing channels form an angle with one another, so that the inlet channel lies essentially in the extension of the first branch channel and is connected to the second branch channel in such a way that the fresh gas flow is directed mainly coaxially in the first branch channel and thereby causes an ejection process.
  • the cross-sectional area of the respective branch duct is many times larger than the smallest cross-sectional surface of the inlet duct, and the length of each branch duct is relatively short and is preferably five times its inner diameter.
  • the breathing channel is assembled with the inlet channel as a compact unit which can be attached to the patient's nose and / or mouth by means of a strip or corresponding means.
  • a further disadvantage of the known CPAP or nCPAP devices lies in the fact that they are not flexible in handling and in connection with compressed air generation devices and pressure measuring devices.
  • the problem underlying the present invention therefore generally consists in creating a simply constructed, light, sterilizable and flexibly connectable CPAP or nCPAP device.
  • the CPAP or nCPAP device with the features of claim 1, ie the device for generating a continuous positive airway pressure with a hollow body in which an overpressure can be built up; a first opening provided in a side wall of the hollow body for supplying an air flow directed into the hollow body and for discharging the exhaled air flow; a connector which can be attached to the hollow body for connecting the hollow body to a nose and / or mouthpiece; and a spacer which can be attached to the hollow body and on which a flow nozzle for directing the Air flow can be attached to the opening has the advantage over the known approaches that it is completely autoclavable and sterilizable due to its compact two-part construction.
  • the idea on which the present invention is based is that a Benveniste valve is provided, the cavity of which can be made accessible over a large cross section by removing the connecting piece from one side, so that an effective sterilization of the cavity is possible. No exhalation hose is necessary during operation.
  • the hollow body and preferably also the spacer, the flow nozzle, the tube can be made of a sterilizable material, such as e.g. Manufacture aluminum or fine aluminum or similar.
  • the connector which is made of Teflon, for example, can also be sterilized or used as a cheap part of the route. In any case, according to the invention there is no need to throw away the expensive finishing component, which is customary in the prior art.
  • the hollow body essentially has the shape of a hollow cylinder, on one end face of which the connecting piece can be attached and on the outer surface of which the opening is provided.
  • the connector consists of a stopper which can be at least partially inserted into the hollow body on the end face.
  • a stopper is easy to attach and remove and, with the appropriate design, has a good seal.
  • the required bushings can be easily provided.
  • the connecting piece has one or two bushings which correspond to corresponding breathing air because of the nose and / or mouthpiece.
  • one or two tube stubs pointing outwards are provided in the leadthroughs of the connecting piece for insertion into the nose and / or mouthpiece.
  • the connecting piece can be rotated relative to the hollow body about at least one specific axis. This enables the position of the connecting piece to be adjusted relative to the patient, so that an optimal laying of the lines is possible.
  • the specific axis lies essentially perpendicular to the axis of the air flow directed into the hollow body.
  • the spacer has an essentially ring-shaped or cup-shaped shape.
  • the flow nozzle is guided through a hole in the side wall of the ring shape or cup shape and is directed essentially perpendicular to the opening.
  • the flow nozzle protrudes a predetermined length into the inside of the ring shape or the inside of the cup shape. This ensures an excellent setup for the flow containers.
  • the spacer is fixedly attached to the hollow body, preferably by crimping.
  • the flow nozzle is fixedly attached to the spacer, preferably by screwing. This also results in a simple adjustment option for the flow nozzle.
  • a second opening for connecting a pressure measuring device is provided in a side wall of the hollow body, preferably different from the side wall with the opening.
  • the hollow body essentially has the shape of a hollow cylinder, on one end face of which the connecting piece can be attached, on the other end face the second opening is provided and on the outer surface of which the first opening is provided.
  • a tube for connection to a pressure measuring line is connected to the second opening at an essentially right angle, preferably using a reinforcing plate attached in the hollow body in the end face.
  • the tube can be rotated relative to the hollow body about at least one specific axis.
  • the tube extends substantially by the same length from the hollow body away as the flow nozzle so that a line for supplying compressed air to the flow nozzle in substantially the "same level as the pressure measuring line can be attached.
  • This construction provides for a expedient attachability of the supply lines.
  • the hollow body and preferably also the spacer, the flow nozzle, the tube and the tube stub or tubes are made of aluminum or fine aluminum.
  • Aluminum or fine aluminum is a common working material that is easy to machine and easy to sterilize.
  • the connector is made of Teflon.
  • Teflon is also a common working material that is easy to work with and easy to sterilize and that also has a good seal on the metal of the hollow body if the connector has the appropriate dimensions. In addition, it can be easily twisted or moved, which is not possible or is only possible with difficulty with a conventional rubber stopper.
  • a nose and / or mouthpiece is provided, which is made of silicone.
  • Figure 1 is a schematic representation of an embodiment of the CPAP device according to the invention.
  • FIG. 2 shows a first cross-sectional view of an exemplary embodiment of a nose attachment piece for connection to the attachment piece
  • FIG. 3 shows a second cross-sectional view of the exemplary embodiment of a nose attachment piece for connection to the attachment piece along the line A-A ', which is indicated in FIG. 2.
  • FIG. 1 shows a schematic representation of an embodiment of the CPAP device according to the invention.
  • the main components of this embodiment of the device according to the invention for generating a continuous positive airway pressure are a cylindrical hollow body 10 in which an overpressure can be built up, a first opening 20 provided in the lateral surface of the cylindrical hollow body 10 for supplying an air flow A directed into the hollow body 10 and for discharging it the exhaled air flow B, a connector 30 which can be attached to the cylindrical hollow body 10 at its one end face 10a, for connecting the hollow body 10 to a nose and / or mouth attachment piece 100, which is explained in more detail in FIGS. 2 and 3, and one which can be attached to the hollow body 10 Spacer 40, on which a flow nozzle 50 for directing the air flow A onto the opening 20 can be attached.
  • the connector 30 consists of a stopper made of Teflon, which can be at least partially inserted into the hollow body 10 on the end face 10a.
  • This stopper is expediently a graduated turned part. It has two bushings (dashed lines) which correspond to the respiratory airways of the nose attachment 100.
  • two outwardly pointing tube stubs 35 are provided for insertion into the nose and / or mouthpiece 100.
  • the connecting piece 30 can be rotated about the cylinder axis relative to the hollow body 10, which is essentially perpendicular to the axis of the air flow A directed into the hollow body 10.
  • a tube 60 for connection to a pressure measuring line is connected to the second opening at a substantially right angle using a reinforcement plate (not shown) attached in the hollow body 10 in the end face 10b.
  • the tube 60 extends essentially the same length away from the hollow body 10 as the flow nozzle 50, so that a line for supplying compressed air to the flow nozzle can be attached to the flow nozzle 50 at substantially the same height as the pressure measurement line.
  • the hollow body 10, the spacer 40, the flow nozzle 50, the tube 60, the reinforcing plate and the tube stub 35 are made of aluminum or fine aluminum.
  • the spacer 40 is fixedly attached to the hollow body 10 by crimping with an inserted ring.
  • the flow nozzle 50 is fixedly attached to the spacer 40 by screwing.
  • the tube 60 is firmly and tightly attached to the hollow body 10 by crimping or screwing.
  • the tube 60 could be attached to the hollow body 10 such that it can be rotated about at least a certain axis, wherein a corresponding tightness as with the connection piece 30 must be ensured.
  • the spacer 40 has a substantially annular shape.
  • the flow nozzle 50 is passed through a hole in the side wall of the ring shape and directed substantially perpendicular to the opening 20.
  • the side wall of the ring shape has a safety air passage opening 45.
  • the ring shape of this construction can be closed with the fingers in such a way that the exhaled air flow B runs through the safety air passage opening 45.
  • FIG. 2 shows a first cross-sectional view of an exemplary embodiment of a nose attachment piece for connection to the attachment piece.
  • the nose piece 100 shown is made of very soft silicone. It has a central part 150 in
  • FIG. 3 shows a second cross-sectional view of the exemplary embodiment of a nose attachment piece for connection to the attachment piece along the line A-A ', which is indicated in FIG. 2.
  • the nose attachment 100 is expediently a disposable part, since silicone hardens during autoclaving and could thus damage the patient's nasal entrances.
  • the dimensions are typically:
  • the air flow supplied through the flow nozzle 50 is typically 10 to 15 liters per minute. As a result, an overpressure proportional to this is built up in the cylindrical cavity 10.
  • the aim is to achieve an exact balance between the amount of gas supplied, the cylinder volume and the diameter of the first opening, so that as far as possible no ambient air is supplied during ventilation that could shift the 0 2 concentration.
  • the outputs to the nose attachment are also optimized so that there is as little dead space as possible when breathing.
  • a water column measuring device with a water lock can serve as the pressure measuring device, otherwise more complex electronic measuring devices can of course also be used.
  • the safety air passage opening on the ring spacer has an important function. If the ring spacer is closed with the fingers on both sides, the pressure increases immediately. This is used to inflate the lungs. However, the safety air passage opening limits the pressure to a predetermined value, which depends in particular on its diameter. If the CPAP device is operated with the above dimensions and the pressure during normal operation is 5 cm water column, then an increase to 12 cm water column is achieved by closing the ring spacer at the side.
  • the dimensions can be chosen according to the respective requirements.
  • the spacer can also be cup-shaped instead of ring-shaped.
  • the cavity can also have a shape other than the cylindrical shape.
