Abstract
A breathing protector for use in a stoma of a laryngectomized or tracheotomised person is provided. This breathing protector is provided with an inlet and an outlet, such that an air flow in use will pass from the surroundings of said person through said inlet to said outlet, into trachea of said person. The breathing protector further comprises a heat-moisture exchanger (3) and a bacteriological filter (4), such that said air flow will pass through said heat-moisture exchanger and said bacteriological filter when said air flow in use passes through said inlet to said outlet. Also, the breathing protector is provided with a closing member (6) that may be activated to close the communication between said at least one inlet and said at least one outlet.
Claims23
A breathing protector for use in a stoma of a laryngectomized or tracheotomised person, said breathing protector having at least one inlet and at least one outlet, such that an air flow in use will pass from the surroundings of said person through said inlet to said outlet, into trachea of said person, said breathing protector comprising:
- a heat-moisture exchanger and a bacteriological filter, such that said air flow will pass through said heat-moisture exchanger and said bacteriological filter when said air flow in use passes through said at least one inlet, to said at least one outlet,
- a closing member selectively activated to close the communication between said at least one inlet and said at least one outlet, and
- a flexible cover.
A breathing protector for use in a stoma of a laryngectomized or tracheotomised person, said breathing protector having a housing with at least a first opening and at least a second opening, such that an air flow in use will pass from the surroundings of said person through said first opening to said second opening, into trachea of said person, said breathing protector comprising:
- a heat-moisture exchanger and a bacteriological filter, such that said air flow will pass through said heat-moisture exchanger and said bacteriological filter when said air flow in use passes through said first opening to said second opening, and
- a rim having a larger circumference than a circumference of said first opening, said bacteriological filter extending from said housing to said rim and covering a cross sectional area of said rim, such that air flow in use will pass from the surroundings of said person through said bacteriological filter before said first opening.
A method for closing a breathing protector for use in a stoma of a laryngectomized or tracheotomised person, said breathing protector having a housing with at least a first opening and at least a second opening, such that an air flow in use will pass from the surroundings of said person through said first opening to said second opening, into trachea of said person, said breathing protector comprising a heat-moisture exchanger and a bacteriological filter, said bacteriological filter enclosing said first opening, such that said air flow will pass through said heat-moisture exchanger and said bacteriological filter when said air flow in use passes through said first opening to said second opening, said breathing protector further comprising a flexible cover external to said bacteriological filter, and
- closing said, first opening by pressing said cover onto said bacteriological filter.
