Problem Statement
- Medical parameters such as breathing rate may be one of best early predictors of decline of health
- Breathing rate trends enables neonatal care, home monitoring of chronically ill, sleep studies on sleep apnea, deception via polygraph and long-term tracking of health conditions of invalids.
- Conventional methods involves the limitations such as restricting patient’s mobility, causing physiological discomfort and psychological stress
Technology
- The said outer covering prepared from a preselected fabric is configured to accommodate a user’s body over the sensing platform at a predefined distance
- The capacitive coupling between the user’s body and the sensing platform creates an electric field, wherein a breathing activity of the user creates a change in the electric field
- The sensing platform comprises a sensing sheet made of a bed linen material with a conductive fabric constituting electrodes
- The said conductive fabric comprises a copper and nickel coated polyester fabric.
- The inner electrode comprises a rectangular shape electrode selected in predefined dimensions
- The two outer electrodes are maintained at a ground potential
- The breathing activity changes each of chest dimensions of the user and abdominal portions of the user.
- Measurement unit comprises an analog to digital converter to generate the output as a digital output for deriving the breathing rate.
- The said measuring unit is configured to measure a change in a variable capacitance due to a change in the electric field
Key Features/ Value Proposition
Technical Perspective:
- The present invention provides a sensing device and method for monitoring breathing rate by the production of electric field created due to a change in the breathing activity of a user.
- Includes a sensing platform with at least one inner electrode connected to a voltage source and at least two outer electrodes maintained at a ground potential and insulating layer and outer layer.
- The said measuring unit measures the variable capacitance created due to a capacitive coupling between the user’s body and the at least two outer electrodes
User Perspective:
- Simple, efficient and cost- effective device which does not restrict the patient mobility
- Also suitable for neonatal patients and burn victims
