INFUSION PUMP MODULE AND INFUSION SYSTEM
First Claim
1. An infusion pump module comprising:
- a body case that includesan inflow channel having an inflow port for a liquid medicine;
a first connecting flow channel;
a second connecting flow channel; and
an outflow channel having an outflow port for the liquid medicine;
an auxiliary case joined to the body case and that includesan auxiliary flow channel connected to the first connecting flow channel and the second connecting flow channel;
a flow sensor that forms a measurement flow channel connected to the second connecting flow channel and the outflow channel, and measures a flow rate of the liquid medicine flowing through the measurement flow channel;
an infusion pump that forms a transfer flow channel connected to the inflow channel and the first connecting flow channel, and discharges the liquid medicine flowed into the transfer flow channel from the inflow channel to the first connecting flow channel by using a piezoelectric element;
a gasket that seals a connection portion between the inflow channel and the transfer flow channel, a connection portion between the transfer flow channel and the first connecting flow channel, a connection portion between the second connecting flow channel and the measurement flow channel, and a connection portion between the measurement flow channel and the outflow channel; and
a cover case that is fastened to the body case to thereby fix the gasket, the infusion pump, and the flow sensor to the body case.
