Breathing protector

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 humidifying and filtering off bacteriological matter, during breathing through a stoma of a laryngectomized or tracheotomised person, said method comprising:

• passing air from the surroundings into trachea of said person through a breathing protector having a housing with at least a first opening and at least a second opening, said breathing protector comprising a heat-moisture exchanger and a bacteriological filter,
• moisturizing said air when passing said air through said heat-moisture exchanger, and
• filtering off bacteriological matter by passing said air through said bacteriological filter, said bacteriological filter having a surface area being larger than the an area enclosed by 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.
