Formula, but present embodiment is without being limited thereto, fixed structure is also possible to the fixed forms such as screw, the fixed structure can also directly by
A connection or multiple connections in air circuit connection is to take into account (in connection while having fixed structure).
In addition, in some instances, it is electronic to exhale after electronic breathing module 20 can connect and fix successfully with ventilator 10
Inhaling module 20 has first communication module and the first controller, and ventilator 10 has second communication module and second controller 14.
In addition, first communication module has third interface 220, second communication module has the tenth interface 120.Third interface 220 and
It can be wired connection between ten interfaces 120, be also possible to be wirelessly connected or plate connects plate socket.
In addition, the signal transmitted between first communication module and second communication module may include that ventilator 10 is supplied to electricity
Data interaction signal etc. between the power supply signal and ventilator 10 and electronic breathing module 20 of dynamic breathing module 20.In addition,
It whether is configured with electronic breathing module 20 if can judge automatically, further includes the detection signal in place of electronic breathing module 20.
In addition, present embodiment is without being limited thereto, for example, if no first controller of electronic breathing module 20, only
There is ventilator 10 to provide the control signal for controlling each component of electronic breathing module 20.
In addition, in the present embodiment, switching device 23 can be three-way solenoid valve.
Certainly, Fig. 2 is schematic diagram, in actual use the 7th interface 111, the 6th interface 112, the tenth interface the 120, the 8th
Interface 121, the 9th interface 122 and some other gas interface, electrical interface etc. can be placed in 10 casing internal of ventilator
's.
In addition, each component in above-mentioned ventilator 10 and electronic breathing module 20 can according to need transposition, such as:
Perhaps first controller etc. can also be set to pilot valve 23a or the in ventilator 10 by switching device 23, Pneumatic three-way valve 23b
Two controllers etc. can also be set in electronic breathing module 20.
Although being illustrated in conjunction with the accompanying drawings and embodiments to the present invention above, it will be appreciated that above description
The invention is not limited in any way.Those skilled in the art without departing from the true spirit and scope of the present invention may be used
To deform and change to the present invention as needed, these deformations and variation are within the scope of the present invention.
