Embodiment Construction

[0051] The body pulsation device, indicated generally at 10 in Figure 1, has a vest 11 and an air pressure and pulse generator 12 operable to apply repetitive pressure pulses to the vest, wherein the vest surrounds a person body placement to provide secretion and mucus removal therapy. Respiratory mucus clearance is useful for many medical conditions such as whooping cough, cystic fibrosis, atelectasis, bronchiectasis, cavitary lung disease, vitamin A deficiency, chronic obstructive pulmonary disease, asthma, and immobilized ciliary syndrome. Mucociliary transport is reduced in postoperative patients, paralyzed persons, and neonates with respiratory distress syndrome. Device 10 provides high frequency chest wall vibrations or pulsations to enhance mucus and airway clearance in a person 13 with reduced mucociliary transport.

[0052] A vest 11 placed around the upper body or rib cage 14 of the person is supported on the shoulders 16 and 17 of the person. As shown in FIG. 2 , ...

Abstract

A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which applies and releases high frequency pressure forces to the body. The pulsator has two diaphragms connected to a brushless electric dc motor with rotary to reciprocating linear motion transmitting mechanisms comprising scotch yokes having anti-lash assemblies operable to generate air pulses in an air pulsing chamber. The diaphragms also increase the pressure in a manifold chamber. A check valve connects the manifold chamber with a pulsing chamber to allow pressurized air to flow from the manifold chamber into the pulsing chamber. An air flow control valve in communication with the manifold chamber is used to adjust the pressure of the air in the manifold and pulsing chambers. A programmable motor controller adjusts the duration of operation and speed of the motor to vary the operational time and frequency of the air pulses.

Description

technical field [0001] The present invention relates to medical devices and methods for repeatedly applying compressive forces to a person's body to assist blood circulation, release and expel mucus from a person's lungs, and relieve muscle and nerve tension. Background technique [0002] Clearance of mucus from the airways in healthy individuals is accomplished primarily by the body's normal mucociliary action and coughing. Under normal conditions, these mechanisms are very efficient. Impairment of the normal mucociliary transport system or mucus hypersecretion in the airways leads to the accumulation of mucus and debris in the lungs and can cause serious medical complications such as hypoxemia, hypercapnia, chronic bronchitis, and pneumonia . These complications can result in reduced quality of life or even be a cause of death. Abnormal respiratory mucus clearance is a manifestation of a variety of medical conditions such as pertussis, cystic fibrosis, atelectasis, bron...
