An IV-solution delivery system for intravenous delivery of a hazardous solution, the system comprising: a drip chamber configured to be attached to a fluid reservoir, the drip chamber having a drip chamber output and a first membrane positioned in the drip chamber output, the first membrane allowing fluid containing a hazardous solution to flow out of the drip chamber at a first rate; a patient conduit having a first end that couples to the drip chamber and a second end that is configured to attach to an intravenous device such that fluid flowing from the drip chamber passes through the patient conduit and intravenous device and into a patient; a second membrane positioned at the second end of the patient conduit, the second membrane having a pore size configured to allow passage of air at a second rate but prevent passage of aerosolized particles of the hazardous solution, and a valve selectively coupled to the second end of the patient conduit, the second membrane forming a portion of the valve, characterized in that the valve further comprises a biasing means that biases the second membrane into a closed position to prevent passage of the fluid containing the hazardous solution through the valve, wherein the biasing means and the second membrane are housed in an internal cavity which further comprises a second end portion having a stepped surface supporting biasing means, and the second membrane and biasing means are interposedly positioned between retaining ridge and the stepped surface within cavity, wherein biasing means is configured to position the second membrane against retaining ridge for forming a seal between the second membrane and the retaining ridge, and wherein when a luer device is coupled to the valve, the biasing means is repositioned to create a flowpath around the second membrane such that the fluid containing the hazardous solution flows through the valve. a drip chamber configured to be attached to a fluid reservoir, the drip chamber having a drip chamber output and a first membrane positioned in the drip chamber output, the first membrane allowing fluid containing a hazardous solution to flow out of the drip chamber at a first rate; a patient conduit having a first end that couples to the drip chamber and a second end that is configured to attach to an intravenous device such that fluid flowing from the drip chamber passes through the patient conduit and intravenous device and into a patient; a second membrane positioned at the second end of the patient conduit, the second membrane having a pore size configured to allow passage of air at a second rate but prevent passage of aerosolized particles of the hazardous solution, and a valve selectively coupled to the second end of the patient conduit, the second membrane forming a portion of the valve, characterized in that the valve further comprises a biasing means that biases the second membrane into a closed position to prevent passage of the fluid containing the hazardous solution through the valve, wherein the biasing means and the second membrane are housed in an internal cavity which further comprises a second end portion having a stepped surface supporting biasing means, and the second membrane and biasing means are interposedly positioned between retaining ridge and the stepped surface within cavity, wherein biasing means is configured to position the second membrane against retaining ridge for forming a seal between the second membrane and the retaining ridge, and wherein when a luer device is coupled to the valve, the biasing means is repositioned to create a flowpath around the second membrane such that the fluid containing the hazardous solution flows through the valve.
