Abstract
A chest brace apparatus prevents the chest wall from buckling inwards during spontaneous breathing efforts and provides negative distending intra-thoracic pressure to a patient. The apparatus includes a protective adhesive layer placed on the patients skin and a brace structure that is designed to attach to the adhesive layer. The adhesive layer has an inner surface and an outer surface, the inner surface adapted to adhere to a chest region of the patient and the outer surface manifesting an outer adherent layer for attachment to the brace structure. The brace structure is placed about the patient's chest region and includes a frontal resilient segment with a patient-side adherent layer for joinder to the outer surface of the adhesive layer, and flexure strips connected to the frontal resilient segment for imparting an outward flexure thereon so as to distend the patient's chest region by outward pressure exerted on the adhesive layer. A pneumatically operated extension device can be connected to the frontal resilient segment for control of distension thereof in response to a pneumatic control action. The brace structure is further adapted to enable manual distension or compression…
