Abstract
A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, connected between an medical gas provider and a patient and configured to 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
A measurement device is disclosed that includes a gas-guide apparatus configured to connect between a medical gas provider and a patient side, and to deliver medical gas from the medical gas provider to the patient. 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, where the detected data represents relative measurement data such as changes in airway pressure, gas flow rate, or respiratory rate.
The sensing apparatus comprises tactile sensing, including at least one first tactile sensor and at least one second tactile sensor. The gas-guide apparatus is arranged with a front-end tube close to the patient and a back-end tube close to the medical gas provider, where the first tactile sensor is placed on an outer surface of the front-end tube and the second tactile sensor is placed on an outer surface of the back-end tube.
A monitoring method executed by a control device receives the real-time measurement data from the measurement device, determines whether the real-time measurement data is abnormal, and in response adjusts an amount of the medical gas according to the real-time measurement data. The method further supports calibration using real-time measurement data detected by a plurality of tactile sensors distributed in an array, producing calibrated measurement data, and then adjusting the amount of the medical gas according to the calibrated measurement data.
In addition, the method can trigger an image capturing apparatus to capture a real-time image of the patient, receive the real-time image, and adjust the amount of the medical gas according to the real-time measurement data and the real-time image of the patient. The method can also compare the real-time image with a preset reference image to determine whether the real-time image is abnormal and send alarm information to a client.
Claims Coverage
The independent claims cover a medical measurement device and control-device-executed patient monitoring methods, with inventive features centered on outer-surface tactile sensing on a gas-guide apparatus, abnormality determination, and adjusting the amount of medical gas, with optional calibration, alarm signaling, and real-time patient image comparison.
Outer-surface tactile sensing on a gas-guide apparatus
A measurement device with a gas-guide apparatus configured to connect between a medical gas provider and a patient side to deliver medical gas, and at least one sensing apparatus placed on an outer surface of the gas-guide apparatus to detect real-time measurement data of the medical gas passing through the gas-guide apparatus.
Patient-side front-end tube and provider-side back-end tube tactile sensors
A gas-guide apparatus comprising a front-end tube, a middle tube, and a back-end tube connected in sequence, where the front-end tube is arranged close to the patient and the back-end tube is arranged close to the medical gas provider, and where at least one first tactile sensor is placed on an outer surface of the front-end tube and the at least one second tactile sensor is placed on an outer surface of the back-end tube.
Abnormality determination and gas amount adjustment based on real-time measurement data
A control-device-executed method that receives real-time measurement data indicating a change in at least one of an airway pressure, a gas flow rate, and a respiratory rate; determines whether the real-time measurement data is abnormal; and in response adjusts an amount of the medical gas according to the real-time measurement data.
Calibration using tactile sensor array and calibrated measurement data adjustment
A method where the sensing apparatus comprises a plurality of tactile sensors distributed in an array, the receiving comprises receiving real-time measurement data detected by the plurality of tactile sensors respectively and performing a calibration to obtain calibrated measurement data, and adjusting the amount of the medical gas comprises adjusting the amount of the medical gas according to the calibrated measurement data.
Real-time patient image capture and joint adjustment using image
A method that triggers an image capturing apparatus to capture a real-time image of the patient, receives the real-time image, and adjusts the amount of the medical gas according to the real-time measurement data and the real-time image of the patient.
Image comparison to preset reference and client alarm information
A method that compares the real-time image of the patient with a preset reference image to determine whether the real-time image is abnormal, and in response sends alarm information to a client.
Overall, the claims cover outer-surface placement of tactile sensing on a gas-guide apparatus delivering medical gas, with real-time measurement data used for abnormality determination and, when abnormal, adjustment of the delivered medical gas amount. Dependent inventive elements further specify tactile sensor array calibration, optional real-time patient image capture with joint adjustment, and abnormality determination and alarm information based on image comparison to a preset reference.
Stated Advantages
Improved measurement security/anti-contamination versus internal sensors by placing sensing apparatus on the outer surface of the gas-guide apparatus.
Documented Applications
Monitoring a condition of a patient receiving medical gas, including determining abnormality and adjusting the amount of medical gas according to real-time measurement data.
Monitoring using both real-time measurement data and real-time patient image for adjusting the amount of medical gas.
Sending alarm information to a client when abnormality is detected based on real-time measurement data and/or abnormal real-time image compared to a preset reference image.
