USER INTERFACE DEVICE PROVIDING IMPROVED SKIN COOLING Russian patent published in 2018 - IPC A61M16/06 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Interface member comprises a first opening for receiving a first gas stream and second openings for discharging the second gas stream from the user interface element. Backing member has a contact portion configured to contact a portion of the wearer's face. First opening and the second openings are disposed relative to each other so that during use of the user interface element, the second gas flow flows around and cools the surface of the user's skin and exits the user interface element through the second holes. Shell member is adapted to receive the lining member. First opening and second openings are provided in the shell member. Shell element includes flow segments. Each of the flow segments includes a chamber having an entrance channel located at the first end of the shell member and open openings spaced from the inlet channel. Each of the openings is one of the second holes. First end of the shell member is adapted to be connected to the lining element, so that the inner chamber of the lining element is in fluid communication with each of the flow segments. In response to the first gas flow through the first orifice, the user interface element is able to provide a second gas flow through each of the flow segments from the inlet channel of the flow segment to the open port of the flow segment. Open flow segment opening is smaller than the inlet channel of the flow segment. Interface device and a method for creating an interface device are disclosed.

EFFECT: technical result is to reduce the user discomfort.
