Problems solved by technology

A hospital admission known as an exacerbation (a type of deterioration in respiratory function) is a significant financial burden on the health care system, as the cost of each exacerbation can exceed $10,000 per event and often results in patient death

Embodiment Construction

[0022] Diaphragm and xiphoid

[0023] To breathe and stay alive, we constantly contract and relax the muscles in our chest and abdomen to breathe about 30,000 times a day. This marathon movement of inhalation and exhalation is performed by the muscles of the diaphragm, abdominals, and thoracic cage. The diaphragm, (Greek for "partition") is the dome-shaped muscle that separates the ribcage, or chest, from the abdomen. During inhalation, the diaphragm contracts and pulls down, while the muscles between the ribs contract and pull up. These movements increase the size of the chest cavity and reduce internal pressure. As a result, air enters and fills the lungs. The diaphragm is the most important muscle used in inhalation. During exhalation, the thorax and chest wall passively begin to droop and return to their original position. At the same time, the diaphragm relaxes and rises. This movement forces the air in the lungs out of the body. Normal breathing is rhythmic, even ...

Abstract

Coughing is a common experience and the most common reason why individuals seek to see a doctor. The incidence of cough is about over 10% of the population. Coughing is a manifestation of many upper respiratory and digestive tract diseases, and especially the consequences of serious lower respiratory tract diseases such as chronic obstructive pulmonary disease (COPD) and asthma, because increasedcoughing can lead to emergency treatment and hospitalization. A method is needed to monitor the frequency of coughing in some patients. Traditionally, all automatic cough monitors use cough sound as asignal to measure a cough. In the present invention, the movement of the diaphragm muscle recorded by a motion sensor located above the xiphoid process is configured to count the coughs. A device forsuch recording is described, and data is collected. The method is validated by using a citric acid spray to trigger the cough sound and show that ab excited acoustic signal matches an electronic signal from the motion sensor.

Description

[0001] This application claims the benefit of provisional application US 62 / 974,276, filed November 22, 2019. technical field [0002] The present invention relates generally to the field of monitoring bodily functions. Background technique [0003] Advances in sensor technology and the transmission of electronic information from sensors to remote receivers have facilitated continuous monitoring of body functions. For example, it is now common to use the Apple Watch to record heart rate and log the number of steps taken each day. Guay et al. (Sensors 17:1050-1063, 2017), and Spire (US 2019 / 0223799) have described devices for attaching to clothing to measure respiration rate. Devices to measure cardiorespiratory fitness are now common in order to help healthy people improve their health and athletic performance. Devices for such monitoring have also been described (Keenan and Coyle, Method and system for processing data from fluid physiology monitoring, US Pat. No. 9,277,87...
