ABSTRACT:
A system is disclosed for detecting extravasation of injected liquid from the blood vessel of a patient. The system operates by monitoring electromagnetic microwave emission from the patient at the injection site by means of a microwave antenna assembly and processing apparatus connected to the antenna assembly for responding to changes in the microwave emission characteristics representative of extravasation. The antenna assembly has a reusable antenna element connected to the processing apparatus, a disposable attachment element for adhering to the patient's skin, and interfitting male and female coupling formations on the attachment element and the antenna element respectively for releasably coupling the reusable element to the disposable element.
