LOW-COST AMBULATORY MEDICAL PUMP

摘要

A low-cost medical pump for ambulatory use provides reduced life components combined with a pump lockout enforcing a safe operating limit and preventing reuse after that limit is exceeded. An improved IV line clamp portion minimizes unsupported clamp structure length and provides a dual lock system preventing inadvertent clamp release.

主权项

1. An ambulatory infusion pump comprising:
a housing holding:
(a) an IV line support structure receiving an IV line set communicating between an IV bag and a patient connection;(b) a fluid pump communicating with the IV support structure to pump fluid through the IV line when the IV line is held in the IV line support structure;(c) a user interface for receiving programming commands from a clinician; and(d) an electronic computer communicating with the fluid pump and the user interface and executing a program stored in non-transient medium to:
(i) monitor operation of the fluid pump to store at least one cumulative pump operation value indicating a cumulative operation of the fluid pump from a time of manufacture of the ambulatory infusion pump;(ii) receive treatment protocol instructions through the user interface describing an intended future operating limit of the fluid pump to pump fluid through an IV line in a treatment protocol;(iii) determine whether an amount of operation of the fluid pump necessary to implement received treatment protocol instructions will exceed a predetermined software-enforced service life of the ambulatory fluid pump reduced by the at least one cumulative pump operation value; and(iv) when the amount of operation of the fluid pump necessary to implement the treatment protocol exceeds the software-enforced service life of the ambulatory fluid pump reduced by the at least one cumulative pump operation value; prevent operation of the fluid pump.
