Abstract:
A tracheostomy valve for connecting to a tracheal tube, which comprises:(a) a valve body having a first end and a second end with a hole extending between the ends and having an inlet spaced apart from the hole; (b) a tubular extension mounted on the first end of the valve body and extending outward from the first end in a direction opposite the second end and having a hole in fluid communication with the hole of the valve body; (c) a flapper valve positioned adjacent the hole of the valve body on the second end of the valve body and having an outer portion and an inner portion connected together so that the inner portion is able to move while the outer portion remains stationary; (d) a valve clamp having a first end and a second end with a hole extending between the ends and positioned such that the first end of the valve clamp is adjacent the flapper valve and the hole of the valve clamp is in fluid communication with the flapper valve; and (e) a cover positioned adjacent the second end of the valve clamp for connecting to the valve body to hold the valve clamp and the flapper valve adjacent the hole of the valve body wherein in use during inhalation, gases flow into the inlet of the valve body from the first side of the valve body to the second side of the valve body into the hole in the valve clamp, through the flapper valve into the hole of the tubular extension and into the tracheal tube and wherein during exhalation, the flapper valve prevents gases from exiting the tracheal tube through the tracheostomy valve.
