3 results about "Normal heart rate" patented technology

The application relates to an exposure method, a medical imaging system, an electronic device and a storage medium, wherein the exposure method comprises the following steps: acquiring heart rate data of an object to be exposed and an exposure period; selecting an exposure mode corresponding to the heart rate data according to the heart rate data; and exposing the object to be exposed according to the exposure mode and the exposure period. According to the application, the object to be scanned with abnormal heart rate and the object to be scanned with normal heart rate can be scanned, and the scanning accuracy is improved.

The application is suitable for the earphone technical field, and provides an earphone and an earphone wearing detection system.The earphone comprises an earphone body, an ear hook, a sensor assembly and a master control unit; wherein the sensor assembly is arranged in the ear hook, and the ear hook is in contact with the ear of a user when the user wears the earphone; the sensor assembly collects heart rate data of the user when the user wears the earphone, and sends the heart rate data to the master control unit; the master control unit is located in the earphone body, is connected with the sensor assembly, and is used for determining that the earphone is successfully worn when the heart rate data sent by the sensor assembly is preset normal heart rate data.Through the sensor assembly in the earphone, the heart rate data meeting the preset normal heart rate data is collected, the successful wearing of the earphone can be accurately determined, the problem that the traditional earphone cannot be detected due to wearing on the head, is placed on the desktop or is mis-triggered by hand holding, and the like, leads to inaccurate earphone wearing detection is solved, and therefore the use experience of the user is improved.

The invention relates to the technical field of valve leaflet cutting, in particular to an anchoring type valve leaflet cutting device. An anchoring type valve leaflet cutting device comprises a shell, a cable, an inner expansion supporting assembly and an outer fixing clamping assembly. The valve leaflet is fixedly clamped between the inner expansion supporting assembly and the outer fixing clamping assembly, and the inner expansion supporting assembly or the outer fixing clamping assembly at least comprises an electric resection arm making contact with the valve leaflet. According to the anchoring type valve leaflet cutting device, valve leaflet capturing and cutting can be achieved under the conventional heart rate, and hypotension and even circulatory collapse are reduced. Meanwhile, the cutting device is superior to the prior art on the aspects of improving the cutting precision and simplifying the operation steps, and is a safe and general valve leaflet cutting instrument.
