| abstract |
The present invention provides means and methods for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising a predefined volume for containing the predetermined volume of the at least one substance; a delivery end for placement in proximity to the body cavity; the delivery end comprises at least one orifice of diameter D [mm]; a valve mechanically connectable to the container, characterized by at least two configurations: (i) an ACTIVE CONFIGURATION in which the valve enables delivery of predetermined volume V sub [ml] of the substance; and, (ii) an INACTIVE CONFIGURATION, in which the valve prevents delivery of the predetermined volume V sub [ml] of the substance from the container to the body cavity; and a fluid tight chamber configured to contain predetermined volume V gas [ml] of pressurized gas at a predetermined pressure, P gas [barg]. |
