1. A noninvasive apparatus for temporarily assisting in treatment of a sucking chest wond, said apparatus comprising:

  • a flexible, annular member for placement in fluid-tight relationship against a patient'"'"'s body and around said wound;

    transparent, rigid, dome-shaped means attached in fluid-tight relationship to said annular member for enabling visual monitoring of levels of fluids escaping from said wound and entering said apparatus beneath said dome-shaped means;

    said dome-shaped means including an annular flange attached in fluid-tight relationship to said annular member;

    a first annular sidewall projecting upwardly from said flange;

    an annular surface projecting inwardly from said sidewall and substantially parallel with said flange;

    a second annular sidewall projecting upwardly from said annular surface;

    a substantially flat element defining at least one aperture therein and connected to upper extremities of said second annular sidewall in substantially parallel relationship with said annular surface; and

    a third annular sidewall surrounding said aperture and projecting upwardly from said flat element;

    valve means in operative relationship with said flat element and said aperture for automatically enabling passage of air in substantially only one direction from within said dome-shaped means outwardly through said aperture and for permitting escape of air from the patient'"'"'s thoracic cavity while preventing air from entering the patient'"'"'s thoracic cavity through the wound;

    a fastening member shaped to fit over and slidably engage said second annular sidewall and to be positioned and held on said annular surface; and

    strapping means attached to said fastening member for holding said fastening member in position on said annular surface and for enabling the adjustable strapping of said apparatus in substantially fluid-tight relationship against the patient'"'"'s body and over the wound.
