Description
SPECIFICATION
A respiration device
This invention relates to a respiration device and is more particularly, but not exclusively, concerned with an anaesthesia respiration device having a respiratory system and a control unit which is connected, via pneumatic control lines, with regulating elements of the respiratory system which are arranged in the respiratory gas line, in order to affect the respiratory gas current.
An anaesthesia respiration device, which has a respiratory system which can be switched, by means of regulating elements, into different operating modes (for example, automatic, manual or spontaneous respiration) according to adjustable values from a control unit is known from DE-A-29 45 485. The control unit, in the known device, is arranged in such a way that the connecting lines from the control unit are fixedly cross-connected to the individual regulating elements and that the respiratory system and the control unit form a sealed unit or device. With such a fixed combination of respiratory system and control unit, it is only possible to interchange the control unit and respiratory system by completely rebuilding the device.The respiratory system provided with the known control unit is merely capable of effecting anaesthetic respiration under semi-closed/semiopen conditions, in automatic and manual operation. A change of respiration from the semiclosed condition to respiration in the completely closed condition is only possible in the case of this known respiration device if the set-up within the respiratory system is modified.
A control unit, connected via control lines with the various regulating elements in the respiratory system, is known from DE-A-29 45 472. This known control unit is arranged inside a respiration device and is able to control the type of respiration only within the constraints of the set-up of the respiration device.
According to the present invention there is provided a respiration device comprising a respiratory system having control lines connected to regulating elements of the respiratory system and a control unit for the said respiratory system, the respiratory system and the control unit being connectible by a connecting piece which comprises a first part associated with the control lines of the respiratory system and a second part associated with control lines leading from the control unit, the two parts being engageable to permit each control line of the control unit to coordinate with a respective control line of the respiratory system.
The present invention provides a respiration device which may be controlled by a control unit which can be chosen irrespective of the respiratory system used.
Preferably, each of the first and second parts of the connecting piece has a face at which each control line, with which that part is associated, terminates.
In a preferred embodiment of the present invention, the control lines are pneumatic control lines. In this preferred embodiment, each control unit conveniently terminates, at its respective face, in an opening such that coordinating control lines coordinate via their respective openings.
Furthermore, the two parts of the connecting piece are preferably engageable in a pressure-tight manner.
Typically, each pair of coordinating control lines is sealed with respect to each other by means of a seal provided at the face of one of the two parts. Each seal is conveniently an elastic thrust piece which surrounds one of the openings of each pair of coordinating openings.
In addition, the first part may be associated with further lines of the respiratory system which further lines conduct respiratory gas from a source which is associated with the second part of the connecting piece.
Moreover, the first part may be associated with signal lines which are connected to measuring sensors in the respiratory system.
The control lines from the control unit to the regulating elements are conducted via a separable connecting piece, which is arranged between the respiratory system and the control unit. At the separating faces of the connecting piece the openings of the control lines coordinate with each other and may be coupled in a pressure-tight manner.
With the device of the present invention a control unit can be set up as a module which has a pneumatic interfaced, via which the control unit may be coupled to a respiratory system, in which case the regulating elements to be controlled can be fixed by engaging the various connections of the connecting piece as required.
This advantage offers the possibility of setting up not only the control unit, but also a respiratory system, as a module, which respiratory system may be coupled with the control unit via the same interface. The various types of respiration or operational states of the respiration device can, with the aid of a programmable control unit, now be brought into line with the respiratory system used.
In addition, it is possible to exchange the respiratory system according to requirements of usage, without having to exchange the control unit or the respiration device as well.
The possibility of coupling both a respiratory system and a control unit with each other as a module inside a respiration device satisfies the need for manifold forms of respiration during artificial respiration or anaethesia. Moreover, a programmable control unit can also be used, adapted to the respiratory systems used in each case, to carry out different performance tests on the respiratory system and the respiration device.
In addition, for disinfection of the device, as is often essential in medicine, it is merely necessary to remove the respiratory system coming into contact with the respiratory gas from the respiration device and to clean it.
Furthermore, it can be advantageous to include additional lines, which are contained in the respiratory system and which conduct respiratory gas, through the connecting piece into the interface as well. The fresh gas line, or ratherthe feed lines of a pneumatic drive unit, may, for example, be one, or some, of said lines.
Advantageously, signal lines from measuring sensors of the respiratory circulation can be taken up in connecting piece, the lines being redirected to an electropneumatic converter, as a result of which the control unit can activate the regulating elements according to the measured values. A converter of this kind can also be provided in order to convert electrical signals, supplied from a purely electronic control unit, into pneumatic control signals for the regulating elements.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made, by way of example only, to the accompanying drawing which shows a diagrammatic representation of a respiration device according to the present invention.
The drawing shows a respiratory system 4 which is suitable for effecting anaesthesia. It is connected to a control unit 3 via a connecting piece 2. The respiratory system 4 contains, as regulating elements, on-off valves 14, 14' and change-over switches 15, 15'. Checkvalves 13, 13' determine the direction of flow of the respiratory gas current.
Fresh gas is fed into the respiratory system 4 via a fresh gas connection 12. An absorber 20 and a charcoal filter 19 serve to process the anaesthetic gas mixture. A pressure sensor 16 is arranged on the inhalation side of the system and a flow sensor 17 is arranged on the expiration side of the system with respect to the lung 21 of the person to receive artificial respiration. A reservoir bag 18 is connected via one of the on-off valves 14. Control lines 1 to the regulating elements 14, 14' and 15, 15', lines 8, which conduct respiratory gas, and signal lines 8, which conduct respiratory gas, and signal lines 9 terminate at half A of the connecting piece 2 which is associated with the respiratory system 4.All of the lines 1,8,9 are passed through as far as a separating face 5 of the half A and emerge at openings 6 which are surrounded by seals 7. Coordinated with the openings 6 are openings 6', which emerge at the separating face 5' of that half B of the connecting piece 2 which is coordinated with the control unit 3.
Control lines 1' and also signal lines 9' are connected from the half B to the control unit 3. The lines 8', which conduct respiratory gas, are connected with a pneumatic drive unit 11.
The various regulating elements are controlled in the respiratory system 4, by means of the control unit 3, via the interface of the connecting piece 2.
The on-off valves 14' are,forexample, closed when the respiratory system is to effect completely closed, automatic anaesthetic respiration. The change-over switch 15 for such respiration is in the switch position of the broken line. The charcoal filter 19 is switched into the circulation in the case of the completely closed anaesthesia by means of the changeover switch 15' when the anaesthetic gas is to be filtered out of the respiratory system. The onoffvalve 14 in the expiratory branch after the flow sensor 17 can be switched in in order to maintain a positive and expiratory pressure (PEEP).
The form of respiration can be changed in a simple manner from completely closed anaesthetic respiration to semi-closed anaesthetic respiration by opening the on-off valve 14' to line 8.
The change-over switch 15 switches over between automatic respiration and manual respiration or spontaneous respiration not only when there is halfclosed respiration, but also when there is completely closed respiration.
The on-offvalves 14, 14' can be closed before the reservoir bag 18 in order to test the tightness of the respiratory system.
When there is a change from the respiratory system 4 represented in the drawing to a respiratory system which is not represented and which has, for example, another combination of on-off valves 14, 14' and change-over switches 15, 15', the new respiratory system can be activated by means of the same control unit 3 providedthatthe interface or half of the connecting piece associated with said system has the same holding of control lines 1, signal lines 9 and lines 8 conducting respiratory gas.
However, it does not matter if all the connections of the connecting piece 2 are engaged or not.
Connections which are not engaged can then either be sealed, or insulated electrically, as required.
