Description:FIELD OF DISCLOSURE
The present disclosure relates to respiratory monitoring devices, and more particularly to a wearable respiratory monitoring device designed for collecting and analyzing airflow data from both nostrils using flexible electronics and wireless communication.
BACKGROUND
Respiratory monitoring is a critical aspect of healthcare, providing valuable insights into an individual's breathing patterns and overall respiratory health. The ability to accurately measure and analyze respiratory parameters such as breathing rate, volume, and airflow characteristics is essential for diagnosing and managing various respiratory conditions, as well as for monitoring general health and fitness.
Conventional respiratory monitoring systems often rely on bulky equipment that restricts patient mobility and comfort. These systems typically involve the use of face masks, nasal cannulas, or chest straps connected to stationary devices, limiting their applicability in everyday settings. Additionally, many existing portable respiratory monitoring devices focus on measuring only a single parameter, such as breathing rate, and fail to provide a comprehensive analysis of respiratory function.
Furthermore, current wearable respiratory monitoring technologies frequently lack the ability to differentiate between airflow from individual nostrils, potentially missing important asymmetries or abnormalities in breathing patterns. The accuracy and reliability of these devices can also be compromised by movement artifacts or improper positioning, leading to inconsistent or unreliable data collection.
Therefore, there exists a need for a technical solution that solves the aforementioned problems of conventional systems and methods for respiratory monitoring.

5. Modular sensor integration: The I2C protocol support allows for easy integration of additional sensor types, enhancing the device's capabilities and adaptability to different monitoring needs.
6. User-friendly power management: The magnetically attached, replaceable batteries provide a convenient solution for extended use and quick battery swaps without disrupting the device's positioning.
This combination of features enables non-invasive, comprehensive, and continuous respiratory monitoring in a compact, wearable form factor, addressing limitations of existing bulky or single-parameter respiratory devices.
Aspects of the present disclosure are discussed here with reference to flowchart illustrations and block diagrams that depict methods, systems, and apparatus in accordance with various aspects of the present disclosure. Each block within these flowcharts and diagrams, as well as combinations of these blocks, can be executed by computer-readable program instructions. The various logical blocks, modules, circuits, and algorithm steps described in connection with the disclosed aspects may be implemented through electronic hardware, software, or a combination of both. To emphasize the interchangeability of hardware and software, the various components, blocks, modules, circuits, and steps are described generally in terms of their functionality. The decision to implement such functionality in hardware or software is dependent on the specific application and design constraints imposed on the overall system. Person having ordinary skill in the art can implement the described functionality in different ways depending on the particular application, without deviating from the scope of the present disclosure.
The flowcharts and block diagrams presented in the figures depict the architecture, functionality, and operation of potential implementations of systems, methods, and apparatus according to different aspects of the present disclosure. Each block in the flowcharts or diagrams may represent an engine, segment, or portion of instructions comprising one or more executable instructions to perform the specified logical function(s). In some alternative implementations, the order of functions within the blocks may differ from what is depicted. For instance, two blocks shown in sequence may be executed concurrently or in reverse order, depending on the required functionality. Each block, and combinations of blocks, can also be implemented using special-purpose hardware-based systems that perform the specified functions or tasks, or through a combination of specialized hardware and software instructions.
Although the preferred aspects have been detailed here, it should be apparent to those skilled in the relevant field that various modifications, additions, and substitutions can be made without departing from the scope of the disclosure. These variations are thus considered to be within the scope of the disclosure as defined in the following claims.
Features or functionalities described in certain example aspects may be combined and re-combined in or with other example aspects. Additionally, different aspects and elements of the disclosed example aspects may be similarly combined and re-combined. Further, some example aspects, individually or collectively, may form components of a larger system where other processes may take precedence or modify their application. Moreover, certain steps may be required before, after, or concurrently with the example aspects disclosed herein. It should be noted that any and all methods and processes disclosed herein can be performed in whole or in part by one or more entities or actors in any manner.
Although terms like "first," "second," etc., are used to describe various elements, components, regions, layers, and sections, these terms should not necessarily be interpreted as limiting. They are used solely to distinguish one element, component, region, layer, or section from another. For example, a "first" element discussed here could be referred to as a "second" element without departing from the teachings of the present disclosure.
The terminology used here is intended to describe specific example aspects and should not be considered as limiting the disclosure. The singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "includes," "comprising," and "including," as used herein, indicate the presence of stated features, steps, elements, or components, but do not exclude the presence or addition of other features, steps, elements, or components.
As used herein, the term "or" is intended to be inclusive, meaning that "X employs A or B" would be satisfied by X employing A, B, or both A and B. Unless specified otherwise or clearly understood from the context, this inclusive meaning applies to the term "or."
Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the relevant art. Terms should be interpreted consistently with their common usage in the context of the relevant art and should not be construed in an idealized or overly formal sense unless expressly defined here.
The terms "about" and "substantially," as used herein, refer to a variation of plus or minus 10% from the nominal value. This variation is always included in any given measure.
In cases where other disclosures are incorporated by reference and there is a conflict with the present disclosure, the present disclosure takes precedence to the extent of the conflict, or to provide a broader disclosure or definition of terms. If two disclosures conflict, the later-dated disclosure will take precedence.
The use of examples or exemplary language (such as "for example") is intended to illustrate aspects of the invention and should not be seen as limiting the scope unless otherwise claimed. No language in the specification should be interpreted as implying that any non-claimed element is essential to the practice of the invention.
While many alterations and modifications of the present invention will likely become apparent to those skilled in the art after reading this description, the specific aspects shown and described by way of illustration are not intended to be limiting in any way.
