Description

FIELD OF THE INVENTION

The present disclosure relates to medical devices, especially to monitors with ultrasonic scanning and monitoring functions, ultrasonic apparatuses, and corresponding methods.

BACKGROUND OF THE INVENTION

Monitors are often used to monitor patients' vital signs when diagnosing and clinically monitoring critical patients. Existing monitors provides cardiac monitoring information which contains parameters about electrocardiograph monitoring (ECG or EKG), blood pressure, oxygen saturation (SPO2) and etc.. The EKG parameter is susceptible to interference such as poor electrode contact and improper manual operation, which may cause the EKG parameter to deviate from actual situation. Accordingly, false alarms may lead to alarm fatigue, resulting in affecting doctors to deal with emergency situation in a timely manner. On the other hand, the blood pressure parameter shown in a display interface of the monitor is usually a numeric-type parameter which has disadvantages of discontinuity and indirect representation of cardiac state. For example, when a low blood pressure is shown in the display interface, a doctor could not tell that is it a problem of heart failure or insufficient blood volume. While with regard to the SPO2 parameter, there may be defects of instability and no real time with the existing monitors.

In some clinical situations, such as heart monitoring in a non-cardiac surgery, observing patient transfer, and supervising intensive care unit (ICU), it may take a long time to monitor real-time parameters of heart movement, for example, noninvasively monitoring hemodynamic parameters such as ejection fraction and left ventricular fraction shortening. Such parameters can only be obtained by not a general monitor but an ultrasonic diagnostic system.

However, a traditional ultrasonic diagnostic system is only disposed in ultrasonic department. At there, a doctor needs to hold an ultrasonic probe for scanning a part to be examined of a patient, thereby obtaining ultrasonic images for a short time diagnosis. With regard to the above-mentioned clinical situations, i.e. monitoring the patient's physiological parameters (including real-time information of organ tissues, such as hemodynamic parameters) for a long time, the existing ultrasonic diagnostic systems could be unable to be applied in such a long time monitoring and hardly meet a wider range of clinical needs. In addition, in the prior art, the probe used for ultrasonic scanning cardiac hemodynamic is usually a probe placed in the esophagus. The patient may feel great discomfort under a long time of monitoring with the esophagus probe.

An alternative way to set the parameter is to offer a plurality of prepared mating parameters stored in the system for a user to choose. Each mating parameter of scanning time (including time for each scanning and interval of scanning) may be further corresponded to a default scanning time parameter under a certain application. For example, various types of prepared scanning time parameters can be predetermined based on different monitoring objects, consequently, a doctor selecting different monitoring objects means that different scanning time parameters may correspondingly be chosen. On the other hand, the scanning period mentioned here may be appreciated to be a fixed interval of time, a fixed scanning time, or an interval of time and scanning time which are varied based on a certain rule.
