Abstract: A collection chamber for fluids and a wide diameter pathway for the removal of air due to leaks from the lung after operation or injury to the contents of the thorax is described. The collection chamber is provided with ports for the attachment of tubing extending from the chest cavity and for connection to a vacuum pump. A water level control vacuum regulator is integral with the chamber which allows a parallel pathway for the removal of large volumes of air from the pleural space without the necessity of a high vacuum. A one-way valve is provided which is open during the drainage mode but which closes during the respiratory inhilation mode to prevent the back flow of air or fluid into the pleural space. In the event of vacuum pump failure, a pressure relief valve is provided to relieve excess positive pressure within the collection chamber.

Abstract: A condom comprises an elongated generally tubular member of thin, flexible material and having an elongated opening provided along at least a substantial portion of the length of the elongated tubular member so as to facilitate placing the elongated tubular member over a flaccid penis. The elongated tubular member may contain a plurality of compartments, each of which contains rheopexic material so that the condom stiffens in use. A slide fastener closure device is provided for closing the elongated opening after placing the condom on a flaccid penis. Further disclosed is an elongated generally tubular member containing rheopexic material for use as an implanted penile prosthesis which stiffens upon agitation.
