Embodiment Construction

[0054] figure 1 is a block diagram of an embodiment of a system for measuring respiratory volume according to the present invention. exist figure 1 In this example, as an example of the sensor working away, the LPG curvature sensor 31 is connected to the lower ribs of the patient 10, preferably between the 6th and 8th ribs, which are located between the parallel sternums, about 10 cm from the left and right sides of the sternum place. The sensor can be self-adhesive, on an adhesive strip, or otherwise attached. Optical fibers 32 and 33 connect the LPG sensor with an interrogation module 34 which converts the optical signal from the LPG sensor 31 into a digital signal proportional to the curvature of the sensor. Since the measurement using the LPG sensor is based on the detection of the transmitted signal, the direction of propagation of the optical signal on the first optical fiber 32 is from the interrogation module 34 to the LPG curvature sensor 31, while on the other opt...

Abstract

The invention is related to a device and method for monitoring respiration, movements in mechanical ventilation in order to provide a non-pneumatic triggering variable for achieving patient-ventilator asynchrony and continuous measurement of tidal volumes. The method is based on measuring the curvature of the patient's torso surface using a single LPG (Long Period Grating) fiber-optic sensor attached to a surface of the torso in an area having high stiffness of the underlying tissue, such as the area of the lower ribs close to the sternum.

Description

technical field [0001] The invention relates to a sensor for measuring the respiratory volume by measuring the movement of the thorax, especially the local curvature change of the torso of a human body. Background technique [0002] The present invention relates to a method and a device for continuous monitoring of the respiration of a patient, especially of a critically ill patient in an intensive care unit. In medicine, mechanical ventilation is a method of mechanically assisting or replacing spontaneous breathing. The method involves a machine called an aerator. There are two main types of mechanical ventilation: 1. invasive ventilation, which uses endotracheal intubation (a tube is inserted through the nose or mouth, and into the windpipe), and 2. non-invasive ventilation, which uses an oronasal mask or mask. In mechanical ventilation, it is necessary to measure tidal volume (Vt, the amount of gas that enters or exits the lungs during quiet breathing) to ensure adequat...
