摘要:
A pulse rate sensor that includes an accelerometer for measuring periodic motion and a piezo sensor for detecting erratic motion is capable of more accurately determining pulse rate by accounting for these types of motion. The pulse rate sensor in accordance with the present invention diminishes pulse rate signal degradation due to erratic motion through a combination of algorithms that control signal boosting, waveform refinement and signal noise suppression.

摘要:
A network communication and messaging protocol for use in a medical perfusion system, provides the rules which govern how, among other things, information and data is conveyed between the various devices which are connect to the network. The rules define the different types of messages that are used in conveying information and data, as well as the formatting for each of those message types. The various messages provide the ability to configure the perfusion system devices, establish links between the perfusion system devices, and convey various types of information and data, even when the main network controller is unavailable.
摘要:
A medical assembly, such as an artificial heart assembly, adapted to be implanted within a living subject is composed of an implantable data communications interface adapted to receive an encoded data signal from a data communications interface located outside the subject at a position remote from the medical assembly. The encoded data signal is transmitted in a plurality of periodic signal bursts, which are transmitted at a first frequency to represent a first data value and a second frequency to represent a second data value. Each of the bursts comprises a plurality of signal transitions having a third frequency greater than both the first and second frequencies.
摘要:
Continuous volume detection for a reservoir in a fluid circuit of a medical system is described. Volume detection is based on a pressure measurement that is manipulated via application of fluid mechanics. Next-generation medical system controllers may use this data to control the volume contained in the reservoir.
