The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist.
Noninvasive blood pressure measuring method and apparatus
InactiveUS6932772B2Exclusion from blood circulationEliminate circulationEvaluation of blood vesselsCatheterTurn angleUlnar artery
A method and a device for non-invasive blood pressure measurement wherein the angle between the hand and the wrist, and the turning angle of the wrist relative to the middle part of the forearm, are kept to the most suitable degree for measuring the blood pressure of the radial artery. At least one pressure bladder and one arterial pulse transducer array are placed on the skin over the radial artery of the wrist to apply the external pressure to the artery and to detect the change of the arterial pulse signals. This method and device can correctly measure the intermittent or continuous blood pressure of the radial artery or the ulnar artery based on the principles of oscillation method and volume compensation method, and effectively eliminate the influence on the measurement due to body movement and the influence on blood circulation and neural function of the hand caused by long-term blood pressure measurement.

Wearable device capable of monitoring heart rate based on photoplethysmography and monitoring method
InactiveCN106037706AUpload location information in real timeFound in timeSensorsMeasuring/recording heart/pulse rateUlnar arteryOlder people
The invention discloses a heart rate monitoring wearable device and a monitoring method based on the photoelectric volumetric method. The invention is based on the photoelectric volumetric method to monitor the heart rate of the elderly in real time. The heart rate measurement module uses a heart rate sensor and embeds the heart rate sensor in a wearable watch middle. The main control chip is C8051F340, which is used to control the work of the sensor as well as signal processing and calculation. In order to make the measurement more accurate, there are two heart rate sensors on each wearable device, which measure the heart rate at the ulnar artery and the radial artery respectively. During the measurement process, due to the intentional or unintentional movement of the elderly, motion artifacts will be generated, which will affect the calculation results. Therefore, the output PPG signal needs to be processed (removing motion artifacts) after being amplified and input to the main control chip after analog-to-digital conversion. Perform heart rate calculations. The present invention uses a compressed sensing algorithm to filter the noise of the PPG signal, and since both the signal and the noise are unknown, the gradient projection algorithm is used to recover the signal, and finally the PPG signal is reconstructed.
