Focused Chest Compression System and Method of Using Same
A system and method are described which permits the directed application of a percussive force to the chest wall to loosen mucus. Airway clearance therapy can be provided by repeated application of air impulses transmitted through the device. The device receives air from an air compressor or pulsating therapy unit (PTU), and forces the air into a flexible membrane inside a cup-like cavity. The open side of the cup is where the membrane expands outwardly into contact the patient's chest when it receives pressure pulses. Rapidly repeated air impulses impact the chest to dislodge mucus adherent to airways within in the lungs. Strategic placement of the device permits focused treatment of affected lung regions. Administration of air impulses to the chest wall is continued until treatment is completed. A pressure sensor can be provided to ensure that the device is properly placed on the patient's body.
1 . A chest percussor system comprising:
a control board;
a shell forming a portion of an air cavity;
a flexible membrane coupled to the shell forming a second portion of the air cavity;
an air inlet configured to provide an impulsive air charge to the cavity, the air charge causing the flexible membrane to expand outward; and
a pressure sensor coupled to a portion of the shell configured to detect when the device is in contact with a chest cavity.
2 . A chest percussor device comprising:
a shell forming a portion of a air cavity;
a flexible membrane coupled to the shell and forming a second portion of the air cavity; and
an air inlet configured to receive an impulse air charge into the cavity, the impulse air causing the flexible membrane to expand outwardly.
