Abstract

A breathing gas supply device is provided which can be taken apart for cleaning purposes. The breathing gas supply device has a modular design in the form of a breathing gas module (2) and a blower module (3), which are inserted together into a housing module (4).

Claims

1. A breathing gas supply device comprising:

a breathing gas module comprising gas ducts and valves connected to an inspiration breathing gas port and to an expiration breathing gas port for a directed breathing gas flow in order to supply breathing gas to a patient and to take up gas expired by the patient;

a blower module comprising a housing, a gas inlet, a gas outlet, a blower impeller and an electric motor for driving said blower impeller in rotation, said housing defining a closed interior with said blower impeller and an electric motor in said closed interior;

a housing module having surface features for receiving said blower module and setting an orientation of said blower module relative to said housing module and having surface features for receiving said breathing gas module and setting an orientation of said breathing gas module relative to said housing module and relative to said blower module; and

a plug and socket coupling arrangement with plugs or sockets of said gas inlet and gas outlet of said blower module and with plugs or sockets connected to said gas ducts and valves of said breathing gas module for detachably connecting said gas inlet and said gas outlet of said blower module to said gas ducts of said breathing gas module via said plug and socket coupling arrangement.

2. A breathing gas supply device in accordance with claim 1, wherein said housing module has electrical contact interfaces with said blower module and wherein said surface features of said housing module include mechanical interfaces with said blower module.

3. A breathing gas supply device in accordance with claim 2, wherein said surface features of said housing module comprise a box-like border for receiving said breathing gas module.

4. A breathing gas supply device in accordance with claim 1, wherein said surface features of said housing module include a pot-shaped depression for accommodating said blower module.
