Abstract:
An improved connector (32) having limited durability for a disposable chest compression vest (12) is quiet and cost effective. Among other advantages, the connector (32) is heat sterilizable and flat so that the vest (12) can be efficiently packaged and stacked, which is particularly beneficial for use in a hospital.
Abstract:
An improved air pulse generator has reduced noise and vibration forces, an improved user interface, reduced size and weight, sweeping oscillating frequency, an electronic flywheel, an improved air pulse module, and internal heat dissipation. The improved air pulse generator also provides prescribed treatment protocols for carrying out high frequency chest wall oscillations.
Abstract:
The present invention is a gas separator for separating a gas mixture into a product gas. The gas separator has an adsorbent bed including a separation chamber with first and second ports and a molecular sieve material contained in the separation chamber. A first pumping chamber is connected to the first port. A first valve regulates flow of the gas mixture between the first port and first pumping chamber. A first piston is located in the first pumping chamber. A second pumping chamber is connected to the second port. A second valve regulates flow of the product gas between the second port and second pumping chamber. A second piston is located in the second pumping chamber. A drive system coordinates operation of the first and second pistons and first and second valves in a cycle including pressurization gas shift and depressurization stages.
Abstract:
A portable high frequency chest wall oscillation (HFCWO) apparatus (10) for the purposes of airway lung clearance and ventilation includes a circumferential chest band (12) which is placed around a person's chest and a drive (14) which is connected to the chest band (12) for cyclically varying the circumference of the chest band (12) to apply an oscillating compressive force to the chest of the person. The apparatus (10) maintains the oscillating compressive force applied by the chest band (12) to the chest of the person at a substantially constant level such that the person is able to continue chest expansions and contractions during a breathing cycle.
