Sequence valve for piggyback IV administration with tube reversal prevention |
摘要 |
A piggyback IV administration system uses a solenoid actuated sequence valve to control the flow of fluid from a pair of IV fluid sources to the inlet of an IV pump or controller. The sequence valve pinches off a first tube while allowing fluid to flow through the second tube and then, in response to a control signal, changes state so that the second tube is pinched off and fluid can flow through the first tube unimpeded. Improper placement of the first and second tubes within the sequence valve during setup is prevented.
