Problems solved by technology

[0007] In 2010, the Joint Commission (which accredits health care organizations and programs in the U.S.) withdrew its dysphagia screening performance standard for acute stroke because it was not endorsed by the National Quality Forum, saying "There are no criteria that constitute a valid dysphagia screening tool, and no clinical trials have been completed to determine optimal swallowing screening

Embodiment approach

[0082] One aspect of the present disclosure is an integrated device for screening swallowing safety and swallowing efficiency. Another aspect of the present disclosure is a method of screening for swallowing safety and swallowing efficiency.

[0083] In some embodiments, the methods and devices may be used in one or more of the following: apparatus and / or methods for detecting aspiration disclosed in US Patent No. 7,749,177 to Chau et al.; Chau et al. Method and / or system for segmentation and duration analysis of biaxial swallowing acceleration measurement signals disclosed in US Patent No. 8,267,875 to Chau et al. for detecting swallowing activity and / or US Patent No. 9,138,171 to Chau et al. or a method and / or device for impaired swallowing detection disclosed in US Patent No. 9,687,191 to Chau et al., each of which is incorporated herein by reference in its entirety.

[0084] As discussed in more detail below, the device may include a sensor (eg, a biaxial accelerometer or...

Embodiment

[0209] The following clinical studies present scientific data that developed and supported one or more embodiments of the device ("dysphagia detection system" or "DDS") disclosed herein for screening swallowing safety and swallowing efficiency. Specifically, embodiments of the DDS test are portable non-invasive devices designed for clinical use. The biaxial accelerometer is contained within the plastic housing of the sensor unit, which is attached to the front of the patient's neck by a single-use, disposable fixation unit just below the palpable lower border of the thyroid cartilage. Vibration was recorded in the superior-inferior axis and the anterior-posterior axis. For this study, the sensor unit was connected via a cable to an A / D converter, which was then connected to a laptop computer.

[0210] The study was the prospective collection and exploration of biaxial accelerometer signals collected by DDS during swallowing time-synchronized with the Video Fluoroscopy Swallow...

Abstract

An integrated device for screening swallowing safety and swallowing efficiency can (i) receive first vibrational data for a first set of swallowing events executed successively by a first individual, (ii) compare at least a portion of the first vibrational data and/or at least a portion of second vibrational data derived from the first vibrational data against preset classification criteria defined for each of swallowing safety and swallowing efficiency, (iii) assign a swallowing safety probability and a swallowing efficiency probability to each of the first plurality of swallowing events, (iv) determine a swallowing safety classification based at least partially on the swallowing safety probability of each of the first plurality of swallowing events, and (v) determine a swallowing efficiency classification based at least partially on the swallowing efficiency probability of each of the first plurality of swallowing events.

Description

Background technique [0001] The present disclosure generally relates to methods and apparatus for screening for impaired swallowing using vibration data, such as acoustic data and / or acceleration measurements. More specifically, the integrated device uses vibration data to screen for swallowing safety and swallowing efficiency. [0002] Dysphagia is characterized by impaired involuntary motor control of the swallowing process, and dysphagia can cause "osmosis" (the entry of foreign substances into the airways). Airway invasion can be accompanied by "aspiration," in which foreign substances enter the lungs and can lead to serious health risks. [0003] The three stages of swallowing activity are the mouth, pharynx, and esophagus. The pharyngeal stage is often impaired in patients with dysphagia. The impaired pharyngeal stage of swallowing in dysphagia is a common health condition (38% of people over 65) and can lead to mealtime aspiration (food entering the airway) and / or ph...
