Problems solved by technology

[0024] However, if it is desired to be able to connect to an auxiliary breathing gas, the aforementioned large size of the connection means is a limitation for miniaturization of the breathing assistance device and more precisely its central unit.
[0025] The second adjustment device constitutes another limit to miniaturization

Embodiment Construction

[0064] Hereinafter, we first describe the breathing assistance device of the present invention with reference to FIG. 1.

[0065] The breathing assist device 1 of the present invention includes a central unit 2 capable of providing breathing gas to the patient.

[0066] The central unit 2 is provided with an outlet 3 through which breathing gas is delivered from the central unit 2 to the patient via the supply device 4. Such an outlet 3 may be, for example, a rubber piece having a tapered shape.

[0067] The supply device 4 is connected to the outlet 3 of the central unit 2 and allows the patient to be supplied with breathing gas from the central unit 2 of the respiratory assist device 1.

[0068] The supply device 4 may constitute a single breathing tube between the patient and the central unit 2.

[0069] The proximal end of the tube is generally connected to the patient through a mask or a device suitable for tracheostomy.

[0070] Alternatively, the supply device 4 may be asso...

Abstract

The invention relates to a breathing assistance device (1) comprising: a first gas inlet (5) for receiving a primary respiratory gas and a first regulating means for regulating said primary respiratory gas, both being located in a central unit (2); a second gas inlet (6) for receiving a secondary respiratory gas and a second regulating means (7) for regulating said secondary respiratory gas; - a controlling means for controlling said first and second regulating means in order to mix said primary and secondary respiratory gases in controlled respective proportions into a controlled mix of gases; - a feeding means (4) for feeding a patient with said controlled mix of gases, characterised in that said second gas inlet (6) and second regulating means (7) are both located in a secondary unit (8) removably connected to the central unit (2).

Description

Technical field [0001] The invention relates to a breathing aid device for patients. [0002] More specifically, the breathing assistance equipment involved in the present invention includes: [0003] -A first gas inlet for receiving the main breathing gas and a first adjusting device for adjusting the main breathing gas; [0004] -A second gas inlet for receiving auxiliary breathing gas and a second adjusting device for adjusting the auxiliary breathing gas; [0005] -A control device, which is used to control the first and second regulating devices so as to mix the main breathing gas and the auxiliary breathing gas in a controlled ratio into a controlled mixed gas; [0006] -A supply device for supplying the controlled mixed gas to the patient. Background technique [0007] The aforementioned breathing aids already exist. [0008] Such equipment includes a central unit, which includes a main source of pressurized gas, such as a turbine for compressing air from the ambient atmos...
