US 2022/0028516 A1 · MEDICATION INFUSION SAFETY DEVICE AND A MEDICATION INFUSION DEVICE COMPRISING THE MEDICATION INFUSION SAFETY DEVICE

Abstract

A medication infusion device comprises a memory means at a medication reservoir storing data identifying medication in the reservoir, a memory reading means at an infusion pump unit reads data from said memory means, and control means controls an infusion, based on data read by said memory reading means, to start the infusion when the medication is correct. A fluid connection detection means detects fluid connection of the medication reservoir to the infusion pump unit and transmits to control means whether the medication reservoir is connected. The control means controls an infusion in accordance with the transmission from the fluid connection detection means so that when there is no connection between the medication reservoir and infusion pump unit, the infusion pump unit will not be started or, if already started, stopped.

A medication infusion safety device, comprising:

a machine-readable label associated with a medication reservoir containing a medication and configured to store data identifying the medication;
a label-reader associated with an infusion pump and configured to read data from the machine-readable label;
the infusion pump comprising a first part which includes a pump mechanism and is provided with a spike adapted to insert into at least one outlet port of the medication reservoir and a second part comprising a motor for driving the pump mechanism of the first part;
an electronic controller adapted to control infusion in accordance with an evaluation of data read by the label-reader;
and
a fluid connection detector configured to detect a flow of medication through the infusion pump and to transmit to the electronic controller a signal indicating whether or not a medication from the medication reservoir is flowing through the infusion pump, the fluid connection detector configured to be provided at an outlet port of the medication reservoir and comprising a flow sensor, wherein the electronic controller is configured to control the infusion additionally in accordance with an evaluation of the signal from the fluid connection detector such that, in case the evaluation of the signal from the fluid connection detector indicates that the medication flowing through the infusion pump is not medication from the medication reservoir but medication from a different medication reservoir that is simultaneously connected to the infusion pump, the electronic controller causes operation of the infusion pump not to be started or, if already started, to be stopped.
