ABSTRACT:
A one-way valve is provided for a multiple blood sample needle which valve is self-sealing between the taking of each sample. The valve is a cup valve which utilizes an annular spike arrangement adjacent the bottom of the skirt of the valve for enhancing the sealing effects thereof. In addition, the pedestal-like internal support for the valve is configured to reduce the degree of deflection inwardly of the skirt of the valve, upon opening, which reduction has the effect of reducing the degree of convolution of the circumferential extent of the skirt during the deflection. The revised internal pedestal support reduces, also, any tendency of the valve to cock out of alignment with the longitudinal axis of the valve and its internal support in its normal position.
