The features of Needle-Free Connectors (NFC) mainly include the following aspects:
Safety: Needle-Free Connectors can effectively reduce the occurrence of accidental needle stick injuries, reduce the risk of occupational exposure, and enhance the psychological safety of medical staff. In addition, needle-free systems help reduce the occurrence of infection and phlebitis.
Ease of operation: Needle-Free Connectors are easy to operate when connecting and disconnecting. When connecting, rotate clockwise to ensure a smooth connection, and when disconnecting, rotate counterclockwise. This design allows needle-free connectors to be connected at any time when flushing or infusion is required, which is convenient and fast.
Sealing: Needle-Free Connectors have a tight, closed, and flat connector passage surface, which can ensure the smooth flow of liquid and reduce the risk of liquid leakage. The positive pressure interface generates positive pressure after the tube is sealed, which can reduce the occurrence of tube blockage caused by blood reflux.
Transparent visibility: Transparent or translucent needleless connectors make it easy for medical staff to observe whether there is blood residue inside the connector, so as to deal with potential contamination problems in time.
Material selection: It is recommended to use materials that do not contain DEHP to avoid affecting the infusion safety of newborns and children.
Classification: Needleless connectors can be divided into positive pressure, negative pressure, balanced pressure and anti-reflux types according to the instantaneous pressure change of the connector after the flushing and sealing operation.
