REUSABLE RESPIRATORY EFFORT SENSOR MODULE

摘要

A respiratory effort sensing belt that incorporates a PVDF transducer is constructed such that the transducer is contained within an elastic, moisture impervious plastic envelope and affixed to the envelope are a pair of cam buckles adapted to receive opposed ends of a body-encircling, single-use band. Because of the construction of the sensor module, it may be sterilized for reuse.

主权项

1. A respiratory effort belt comprising:
a) a PVDF film strip having a layer of metallization on opposed major surfaces thereof; b) first and second insulated leads each with first and second ends, the first end of the first lead electrically connected to the layer of metallization on one of the opposed major surfaces and the second lead electrically connected to the layer of metallization on another of the opposed major surfaces; c) a flexible, elastic, moisture impervious, generally rectangular elastomeric envelope containing the PVDF film strip and only a distal end portion of the first and second conductive leads, the envelope having first and second end portions; and d) a pair of connectors releasably attached individually to said first and second end portions of the envelope and adapted to be releasably affixed to opposed ends of a disposable band of a length sufficient to encircle a human's torso.
