Infiltration indicator and alarm |
摘要 |
In an infusion system, a source of pressurized liquid infusate is connected to the upstream end of a small-bore flow restrictor and drives a flow of infusate therethrough; the downstream end of the flow restrictor is connected to the patient. The infusate at the upstream end is in communication with an annulus inflatable by infusate pressure of at least 200 to 500 Torr; the infusate at the downstream end is in communication with another annulus inflatable by infusate pressure of only 35 to 110 Torr, as occurs during infiltration. Inflation of an annulus provides a visible indication and can provide electrical contact for an alarm.
