Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a schematic configuration diagram showing the auxiliary artificial heart system 7 of the present embodiment. The auxiliary artificial heart system 7 includes an auxiliary artificial heart 5 and an abnormality detection device 10 .

[0027] The auxiliary artificial heart 5 is implanted in the body of the user 3 (patient). The auxiliary artificial heart 5 is equipped with a liquid pump. The liquid pump sucks in the blood of the user 3 and sends it out. The liquid pump is operated by electricity. In addition, the auxiliary artificial heart 5 notifies the abnormality detection device 10 of its own operating state as operating information. Examples of the operating state include the voltage value supplied to the liquid pump, the current value, power consumption, the rotational speed of the liquid pump, and the blood flow rate.

[0028] In addition, sensors ...

Abstract

In order to provide an abnormality detecting device for a heart assist device, a method for detecting an abnormality of a heart assist device and an abnormal state of a heart assist device detecting program which can early detect an abnormal state, the abnormality detecting device for a heart assist device according to the present invention includes a user information acquiring means for obtaining user information that indicates an operation state of the heart assist device implanted in a body of a user or a biological state of the user measured by the heart assist device and associating said user information with time to store in a history information storing means, and an abnormal state judging means for referring said history information storing means and judging whether or not an abnormal state is present based on a history of said user information.

Description

technical field [0001] The invention relates to an abnormal detection device for an auxiliary artificial heart, an abnormal detection method for an auxiliary artificial heart and an abnormal detection program for an auxiliary artificial heart. Background technique [0002] In recent years, medical equipment has been highly developed. Due to the sophistication of medical equipment, the development of miniaturization of medical equipment is also brought about. Assistive artificial hearts are also moving towards miniaturization and the ability to be implanted in the user. The auxiliary artificial heart is carried by the patient by being implanted in the body. [0003] The auxiliary artificial heart carried by the patient lacks an alarm device. An alarm device is usually configured to acquire physiological information of a patient and information indicating the operating state of the device itself. When the alarm device detects abnormalities in physiological information and ...
