Abstract
A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, configured to operatively connect between an medical gas provider and a patient side of the measurement device, and deliver medical gas from the medical gas provider to the patient; and at least one sensing apparatus, placed on an outer surface of the gas-guide apparatus and configured to detect real-time measurement data of the medical gas passing through the gas-guide apparatus. In this way, the at least one sensing apparatus is placed on the outer surface of the gas-guide apparatus, since the measurement data is a relative value which indicates a change of internal environment of the gas-guide apparatus, this can also avoid a problem of contamination compared with setting a sensor inside a respiratory device, thus improving the security of the measurement.
Core Innovation
The invention relates to a measurement device for patient monitoring in which medical gas is delivered through a gas-guide apparatus configured to operatively connect between a medical gas provider and a patient side. At least one sensing apparatus is placed on an outer surface of the gas-guide apparatus and detects real-time measurement data of the medical gas passing through the gas-guide apparatus, and the real-time measurement data is used as a relative measurement value for patient monitoring during respiratory support.
The sensing apparatus comprises a first tactile sensor and a second tactile sensor placed at different positions on the outer surface of the gas-guide apparatus, including different tube positions on the gas-guide apparatus. The sensing configuration may include an array of tactile sensors and placement using different tube wall structures for positioning the sensors.
The gas-guide apparatus and sensing are arranged to reduce contamination risk by sensing on the outer surface rather than using sensors placed in internal or proximal invasive positions. The device configuration includes a non-heated respiratory tube at a front-end portion and a heated respiratory tube at a back-end portion to reduce condensation and reduce noise.
The device performs abnormality determination using preset threshold(s), triggers an alarm signal when abnormality is detected, and communicates measurement results to a control device, with optional preliminary filtering. It also supports multimodal abnormality determination using triggered real-time patient imaging compared with a preset reference image, alarm information sent to a client, respiratory parameter visualization data issued to a display apparatus, and adjustment of the amount of supplied medical gas in a closed-loop manner based on detected abnormal measurements.
Claims Coverage
The provided independent claim defines a measurement device with two main inventive aspects: outer-surface sensing on a gas-guide apparatus that connects a medical gas provider to a patient side, and tactile sensor placement using first and second tactile sensors at different outer-surface positions.
Outer-surface sensing on a gas-guide apparatus for real-time measurement data
A gas-guide apparatus configured to operatively connect between a medical gas provider and a patient side of the measurement device to deliver medical gas, where at least one sensing apparatus is placed on an outer surface of the gas-guide apparatus and detects real-time measurement data of the medical gas passing through the gas-guide apparatus.
First and second tactile sensors at different outer-surface positions
The at least one sensing apparatus comprises at least one first tactile sensor and at least one second tactile sensor, where the at least one first tactile sensor and the at least one second tactile sensor are placed at different positions on the outer surface of the gas-guide apparatus.
Within the scope of the provided independent claim, claim coverage centers on placing sensing apparatus on the outer surface of the gas-guide apparatus to detect real-time measurement data of medical gas, and using tactile sensing with first and second tactile sensors located at different outer-surface positions. Dependent refinements described in the provided material further include abnormality determination using preset threshold(s) with alarm signaling and optional multimodal abnormality determination using real-time patient imaging compared to a preset reference image, with visualization and communication to a client.
Stated Advantages
Reduce contamination risk by placing sensing elements on the outer surface of the gas-guide apparatus rather than in internal/proximal invasive positions.
Reduce condensation and noise by using a non-heated respiratory tube at the front-end portion and a heated respiratory tube at the back-end portion.
Provide abnormality determination using preset threshold(s) and trigger alarm signaling when measurement data is abnormal.
Support multimodal abnormality determination using real-time patient imaging compared to a preset reference image.
Provide respiratory parameter visualization data for a display apparatus and send alarm information to a client.
Documented Applications
Patient monitoring for respiratory support using a measurement device in which medical gas is delivered via a gas-guide apparatus and real-time measurement data is detected on the outer surface of the gas-guide apparatus.
Abnormality detection during respiratory support by determining abnormality from real-time measurement data and triggering alarm signaling.
Multimodal patient monitoring by capturing triggered real-time patient imaging and comparing it to a preset reference image to determine abnormality and issue alarm information.
Visualization of respiratory parameter data by generating respiratory parameter visualization data and issuing it to a display apparatus, with alarm information sent to a client.
