Pressure monitoring system for infusion pumps

摘要

A pressure monitoring system allows for more accurate and reliable measurement of the pressure inside of a tube in a pump. The pressure monitoring system prevents movement of the tubing or a change in size of the tubing due to external forces applied to the pump, eliminating inaccuracies due to handling of the pump during use.

主权项

1. A pressure monitoring system for a pump comprising:
a pump having a pressure monitoring channel defined by opposing sidewalls, each sidewall having an upper surface; a tubing disposed in the pressure monitoring channel between the opposing sidewalls; a pressure sensor disposed in communication with the tubing to monitor the pressure in the tubing; a pump door having an inside surface and an outside surface, the door including a closure mechanism configured to releasably secure the pump door relative to the pump; a projection disposed on the inside surface of the pump door;
wherein, in an open position, the pump door has a first shape;wherein, in a closed position, the projection is configured to contact the upper surfaces such that the pump door is bent outwardly into a second shape and thereby bias the projection towards the pressure monitoring channel;wherein, when the door is closed, the projection is configured to engage both the tubing and the upper surfaces of the opposing sidewalls.
