Abstract
A drug solution administration unit including a drug solution administration module having a first flow path unit, a second flow path unit, and a drive mechanism unit, and a drug solution administration device having a branch path and a main path. The first flow path unit includes an upstream side main body where a first flow path to store drive solution is formed, and the second flow path unit includes a downstream side main body where a second flow path to store drug solution is formed. The drive mechanism unit includes a pair of electrodes and a porous body sandwiched between the pair of electrodes, the drive mechanism unit has a connecting flow path connecting a downstream end of the first flow path and an upstream end of the second flow path.
Core Innovation
A medication management system includes a drug solution administration module and a drug solution administration device. The module stores drive solution in a first flow path unit and stores drug solution in a second flow path unit, and a drive mechanism unit includes a pair of electrodes and a porous body sandwiched between the pair of electrodes.
The drive mechanism unit has a connecting flow path connecting a downstream end of the first flow path and an upstream end of the second flow path. When voltage is applied, drive solution permeates the porous body to cause electroosmotic flow that pushes the drug solution downstream quickly and safely, and the drive stops when the drive solution is exhausted.
The drug solution administration device mounts the drug solution administration module and routes output via a housing with a containment unit. Inside the housing, a branch path connects the second flow path to a main path that connects to an intravenous tube, and the device includes an upstream connecting unit and a downstream connecting unit for the main path, with a flow path connecting unit at an upstream end of the branch path that is connected to the drug solution connecting unit.
The system further includes analysis/learning to predict a recommended flow rate and vital outcomes based on patient attribute data and drug solution flow/timing data. It supports multi-module operation patterns including continuous, intermittent, simultaneous, and compensating patterns, and uses module identification verification via RFID/tag unit reading and nonconformity alerts, including module-ID collation in a daisy chain connection.
Claims Coverage
The partial content contains one independent claim. The independent claim defines a drug solution administering unit comprising a specific electrode-and-porous-body drive mechanism module and a drug solution administration device having branched flow paths connected to an intravenous tube, yielding a set of inventive features that cover both the module drive architecture and the device routing/connection architecture.
Electrode and porous-body drive mechanism with connecting flow path
A drive mechanism unit including a pair of electrodes and a porous body sandwiched between the pair of electrodes, the drive mechanism unit having a connecting flow path connecting a downstream end of the first flow path and an upstream end of the second flow path.
Module with upstream drive-solution flow path and downstream drug-solution flow path
A drug solution administration module comprising a first flow path unit including an upstream side main body where a first flow path to store drive solution is formed, and a second flow path unit including a downstream side main body where a second flow path to store drug solution is formed.
Drug solution connecting unit at downstream end of second flow path
Wherein the drug solution administration module has a drug solution connecting unit at a downstream end of the second flow path.
Housing with containment unit and branched flow paths to intravenous tube
A housing where a containment unit to store the drug solution administration module is formed, inside of the housing a branch path where the second flow path is connected, and inside of the housing a main path that is branched from a downstream side of the branch path and connected to an intravenous tube.
Upstream and downstream connecting units connecting main path to intravenous tube
The main path connects an upstream connecting unit with a downstream connecting unit; the upstream connecting unit connects the main path with the intravenous tube on an upstream side; and the downstream connecting unit connects the main path with the intravenous tube on a downstream side.
Flow path connecting unit at upstream end of branch path to connect to drug solution connecting unit
Wherein the drug solution administration device has a flow path connecting unit at an upstream end of the branch path to which the drug solution connecting unit is connected.
Overall, the claim coverage is centered on an integrated drug solution administering unit that couples a porous-body electrode drive mechanism with separated drive-solution and drug-solution flow paths, and a device housing architecture that routes the drug solution to an intravenous tube through a branch path and a main path using upstream/downstream connecting units.
