Zusammenfassung:	A check valve assembly for use in medical devices having a single valve disc therein to allow a medical fluid to be drawn from a bulk container through the inlet opening and secondary opening of the valve assembly and into a syringe and then subsequently dispensing the fluid from the syringe through the secondary opening and outlet opening of the valve assembly and into a second container or to the patient. Alternately, the valve assembly may be used with a squeeze bulb of an aspiration device such that as the bulb is squeezed, the air in the bulb passes from the secondary opening to the outlet opening of the valve assembly and then, as the bulb is released, the negative pressure from the bulb is transmitted through the secondary opening and inlet opening of the valve assembly to the aspiration device to draw fluids from the patient and into the aspiration device.
