PUMP CASSETTE WITH RADIO FREQUENCY IDENTIFICATION TAG
Aspects of this disclosure relate to a pump cassette with a radio frequency identification (RFID) tag. The RFID tag can store information associated with the pump cassette, such as usage information and/or a unique identifier. The RFID tag can be embedded in a component of the pump cassette in certain embodiments. Related infusion pumps, infusion sets, and infusion systems are disclosed.
1 . A pump cassette for fluid delivery, the pump cassette comprising:
a housing dimensioned to engage with an infusion pump;
a fluid path within the housing, the fluid path configured to receive fluid from a fluid source and to deliver the fluid to tubing of an infusion line; and
a radio frequency identification tag embedded in a component of the pump cassette.
2 . The pump cassette of claim 1 , wherein the radio frequency identification tag is surrounded by molding material of the component.
3 . The pump cassette of claim 1 , wherein the component is a mechanical component.
4 . The pump cassette of claim 1 , wherein the component is a flow stop valve.
5 . The pump cassette of claim 1 , wherein the radio frequency identification tag stores an identifier uniquely identifying the pump cassette.
6 . The pump cassette of claim 1 , wherein the radio frequency identification tag stores pairing information for wireless communication with a light set.
7 . The pump cassette of claim 1 , wherein the radio frequency identification tag stores cassette usage information.
8 . The pump cassette of claim 1 , wherein the radio frequency identification tag stores information identifying one or more pump cassette parameters.
9 . The pump cassette of claim 1 , wherein the fluid path comprises an air trap and a pumping chamber.
10 . The pump cassette of claim 1 , wherein the pump cassette is configured to independently control pumping for a primary infusion and a secondary infusion.
11 . The pump cassette of claim 1 , wherein the fluid path is U-shaped.
12 . The pump cassette of claim 1 , wherein the pump cassette is configured to deliver a set volume of the fluid with each pumping cycle.
13 . An infusion pump for fluid delivery, the infusion pump comprising:
a housing configured to a receive a pump cassette; and
an antenna configured to wirelessly communicate with a radio frequency identification tag of the pump cassette when the pump cassette is engaged with the housing, wherein the antenna is arranged to be aligned with a flow stop valve of the pump cassette when the pump cassette is engaged with the housing,
wherein the infusion pump is configured to control infusion of fluid to a patient.
14 . The infusion pump of claim 13 , further comprising a processor configured to perform a safety check based on information from the radio frequency identification tag read by way of the antenna, and to cause infusion of the fluid based on passing the safety check.
15 . A method of operating an infusion pump, the method comprising:
reading information from a radio frequency identification tag embedded in a component of a pump cassette; and
controlling infusion, by the infusion pump, based on the information from the radio frequency tag.
16 . The method of claim 15 , further comprising writing, by the infusion pump, to the radio frequency identification tag during infusion.
17 . The method of claim 15 , further comprising writing information indicative of a start time of infusion to the radio frequency identification tag.
18 . The method of claim 15 , further comprising writing information indicative of a medication delivered to a patient to the radio frequency identification tag.
19 . The method of claim 15 , wherein the controlling infusion comprises verifying a pump cassette based on the information.
20 . The method of claim 15 , wherein the controlling infusion comprises performing a safety check related to at least one of previous usage of the pump cassette or a condition of the pump cassette.
