The present disclosure relates generally to medical connectors used in fluid transfer applications. More particular, it relates to a vial adapter for the transfer of fluids in medical settings without exposure of the fluid to an ambient atmosphere.
Medical connectors are widely used to transmit, prepare, and deliver medical fluids. The preparation of a medical fluid may include the delivery, dilution, reconstitution, and withdrawal of a medical fluid or a component thereof with a container such as a vial.
In some instances, such as with chemotherapy treatment, the medical fluid is hazardous. Particularly, repeated exposure to the medical fluid, such as by medical personnel, is hazardous. An example instance of medical fluid transfer is the reconstitution of a medication. Reconstitution is often conducted within a sealed vial containing a medical fluid, or a constituent thereof, in any state of matter. This process requires a diluent to be delivered into the vial. However, delivery of the diluent into the sealed vial causes displacement of gas within the vial. If the gas were permitted to enter the ambient atmosphere, people within the ambient atmosphere may be exposed to the gas. In some instances, the medical fluid itself may be transmitted into the ambient atmosphere during reconstitution.
