Abstract
Fluid transfer systems are disclosed that can be configured to transfer precise amounts of fluid from a source container to a target container. The fluid transfer system can have multiple fluid transfer stations for transferring fluids into multiple target containers or for combining different types of fluids into a single target container to form a mixture. The fluid transfer system can include a pump and a destination sensor, such as a weight sensor. The fluid transfer system can be configured to flush remaining fluid out of a connector to reduce waste, using air or a flushing fluid.
Claims25
A medical fluid transfer system comprising:
- a hose assembly being configured to couple to a source container and to couple to a target container;
- a fluid transfer station comprising a housing and a peristaltic pump, the fluid transfer station being configured to transfer fluid through the hose assembly;
- a destination sensor being configured to measure a weight of the target container, the destination sensor comprising a sensor housing being separate from the housing of the fluid transfer station;
- a sensor being configured to detect a presence of a connector of the fluid transfer system;
- and
- a control system being configured to:
- receive instructions, the instructions comprising a fluid transfer instruction;
- operate the peristaltic pump using the fluid transfer instruction to selectively transfer fluid to the target container;
- receive weight information about the target container from the destination sensor;
- and
- operate the peristaltic pump using the weight information about the target container.
An electronic medical fluid transfer system being configured to fill IV bags with medical fluid, the electronic medical fluid transfer system comprising:
- a hose assembly being configured to couple to a source container and to couple to an IV bag;
- a fluid transfer station comprising a housing and a peristaltic pump, the fluid transfer station being configured to transfer fluid through the hose assembly;
- a destination sensor comprising a sensor housing being separate from the housing of the fluid transfer station, the destination sensor being configured to measure a weight of the IV bag;
- a sensor being configured to detect a presence of a connector of the fluid transfer system;
- a control system being configured to:
- receive instructions, wherein the instructions comprise a fluid transfer instruction;
- operate the peristaltic pump using the fluid transfer instruction to selectively transfer fluid to the IV bag;
- receive information about a weight of the IV bag from the destination sensor;
- and
- operate the peristaltic pump using the information about the weight of the IV bag;
- a scanner being configured to scan information from at least one of a source container or a prescription;
- a printer being configured to print a label for the IV bag;
- a foot pedal being configured to send a signal to perform a fluid transfer;
- and
- a communication interface being configured to communicate with a remote source.
A medical fluid transfer system comprising:
- a hose assembly being configured to couple to a target container;
- a fluid transfer station comprising a housing and a peristaltic pump, the fluid transfer station being configured to transfer fluid through the hose assembly;
- a destination sensor being configured to measure a weight of the target container, the destination sensor comprising a sensor housing being separate from the housing of the fluid transfer station;
- a sensor being configured to detect whether a connector of the hose assembly is open;
- and
- a control system being configured to:
- receive instructions, the instructions comprising a fluid transfer instruction;
- operate the peristaltic pump using the fluid transfer instruction;
- receive weight information about the target container from the destination sensor;
- and
- operate the peristaltic pump using the weight information about the target container.
