Problems solved by technology
[0007] In the past, ultrasonic probes were highly inspected and tested by servicemen through regular inspections, but they were limited to simple inspections and tests in daily inspections.
In daily inspection, only visual test or simple image test can be performed, and it is difficult to find faults such as no abnormality in appearance
In regular inspection or daily inspection, since the main cause of abnormal occurrence during storage and transportation cannot be determined, the possibility of abnormality cannot be found, and the uncertainty of the main cause of this abnormal occurrence also makes it difficult to find faults
If the main cause of the abnormality cannot be determined, it is difficult to judge what kind of operation the abnormality will occur, and it is difficult to perform appropriate operations

Embodiment Construction
[0036] Hereinafter, preferred embodiments of the ultrasonic probe of the present invention will be specifically described with reference to the drawings.
[0037] FIG. 1 is an external view showing an ultrasonic probe. The ultrasonic probe 1 transmits ultrasonic waves to a subject, and receives reflected waves generated due to a mismatch of acoustic impedance (impedance) inside the subject. The ultrasonic probe 1 is used while being connected to an ultrasonic diagnostic device D1 (see FIG. 3 ). The received reflected wave is converted into an electrical signal, and the electrical signal is output to the ultrasonic diagnostic device D1. The ultrasonic diagnostic apparatus D1 performs image processing on the input electric signal and displays an image of the inside of the subject.
[0038] This ultrasonic probe 1 is constituted by an ultrasonic transmitting and receiving unit 2 , a connector unit 3 and a cable unit 4 . The ultrasonic transceiver unit 2 transmits and receives ...

An ultrasonic probe comprises: an internal power source configured to be capable of supplying electrical power to the inside in a state in which the ultrasonic probe is detached from an ultrasonic diagnostic device; and a state-management part configured to be fed with power from the internal power source and manage the state of an ultrasonic probe's main body. Consequently, it becomes possible to manage in real time the state of the ultrasonic probe in non-use. The state management in non-use allows for the factors behind abnormality occurrences to be specified and for secure storage management to be accomplished.
Description
technical field [0001] The present invention relates to management technology of ultrasonic probes. Background technique [0002] In ultrasonic diagnosis, ultrasonic waves are transmitted into a subject, and diagnostic information such as a tomographic image in the subject is generated based on reflected waves reflected in the subject. Transmitting and receiving of ultrasonic waves to a subject is performed by an ultrasonic probe. [0003] An ultrasonic probe includes an ultrasonic vibrating element having a piezoelectric effect that reversibly converts electric current and sound waves. Ultrasonic vibration elements generate ultrasonic waves when voltage is applied, and generate electrical signals when they receive reflected waves. The ultrasonic probe is connected to an ultrasonic diagnostic device when used for ultrasonic diagnosis. The ultrasonic probe is connected to an ultrasonic diagnostic device, and is driven by receiving power from the ultrasonic diagnostic devic...
