摘要： A self-sealing male Luer connector attaches to any standard female Luer valve to open a flow channel between the two. The self-sealing male Luer connector includes a rigid housing having a distal end with a rigid male Luer connector and a proximal end at which a proximal seal is formed. The distal end of the housing includes a valve seat. Located within the housing is a resilient biasing member that biases an actuator into contact with the valve seat to prevent fluid flow through the male connector. Upon engagement with a female connector, the actuator is moved in the proximal direction to open the distal valve and then the proximal seal. A partial vacuum is formed within the male connector upon disengagement with the female connector that draws any fluids on the external surface of the distal end of the male Luer connector into the male tip.

摘要： A medication cabinet that includes at least one drawer, a drive mechanism, and a drawer latching mechanism, is disclosed. The drawer includes a slider, and a container that includes a receptacle and a lid that moves between an open position and a closed position. The container also includes a fastener to fasten the lid to the receptacle. The slider maintains the lid in the closed position when at least a portion of the wall is coupled with the fastener, and actuates the lid from the closed position to the open position when the fastener passes through an opening in the wall. The drive mechanism controls longitudinal movement of the slider, and is mounted to the chassis, allowing the drawer to be free of electrical connections with the chassis. When the drive mechanism is not used to move the lid into the open position, longitudinal movement of the slider is inhibited.

摘要： An apparatus and method are provided to verify the composition of a medical fluid in a fluid container. The verification is performed at a centralized location, where light is transmitted through the fluid and detected by a sensor that generates signals representative of the spectral data of the actual composition of the fluid. These signals are compared with the spectral data of an expected composition of the fluid. Based on the comparison, a label is generated that identifies the composition of the fluid and is affixed to the fluid container. The fluid container, with the verified fluid, is distributed to the point of care.

摘要： A vented vial adapter has a filter attached to a vent arm that includes at least two filter media for suppressing aerosolized medicaments from leaving the vial and suppressing bacteria and other contaminants from entering the vial during reconstitution activities of the medication in the vial. The filter media allows the passage of air to the atmosphere outside the vial for pressure equalization. In another aspect, a third filter medium is used in the vent of the adapter to allow gas to pass in either direction through it, but prevents bacteria and particulate matter in the atmosphere from reaching the second filter device. A first filter is hydrophobic and prevents non-dispersed liquid from reaching the second filter, while conducting liquid dispersed in gas. The second filter absorbs the liquid dispersed in gas.

摘要： An automatic stop valve formed in a container of a medical fluid administration system includes an electrical field that attracts the float and valve seat together to shut off flow from the exit port of the container when the fluid within the container is reduced to a predetermined level. One or both of the float and valve seat creates an electric field that attracts the other, which is made of a non-magnetic dielectric, into engagement. In one embodiment, the valve seat is formed of an electret that creates the electric field attracting the float to it to stop flow. In another embodiment, the float comprises an electret that attracts the float to the dielectric valve seat. In yet another embodiment, both the float and valve seat include electrets of opposite polarity that attract each other into engagement. The lack of magnetic and metallic materials makes the shut off valve suitable for use in an MRI environment.

摘要： A needle free medical connector includes a housing with a first port and a second port. The connector also includes a piston element defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has a compressible section having a variable inner width that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the compressible section self-expands in width thereby maintaining or increasing the volume of the fluid passageway through the connector. The compressible section has a configuration permitting the continuous flow of fluid through its entirety.

摘要： A system and method for determining whether the pressure in a fluid line upstream of an infusion pump is becoming lower as pumping draws fluid from the fluid line and fluid container due to a lack of proper venting. An initial pressure is sensed by an upstream pressure sensor at the start of an infusion. After a period of time, which may be determined either by monitoring infusion time or the number of pump cycles completed, a second pressure is sampled and compared to the initial pressure. Various analytical methods may be applied to the sensed pressures to determine upstream pressures or trends. Where an upstream pressure reading indicates a lack of proper venting, an alert signal is provided. Continuous monitoring may occur in which succeeding samples are compared to preceding samples to determine upstream pressures or trends.
