A patient monitor () acquires a vital sign that is based on a physiological signal of a subject, and an ultrasonic image that is based on a reflected wave of an ultrasonic wave which is irradiated onto the subject. A display section () displays information of the subject. A control section () switches between a first mode in which a screen containing information of the vital sign is displayed on the display section (), and a second mode in which a screen containing the ultrasonic image is displayed on the display section ().

Patient monitor, physiological information measurement system, program to be used in patient monitor, and non-transitory computer readable medium in which program to be used in patient monitor is stored

A physiological information measurement apparatus is configured to acquire a vital sign that is based on a physiological signal of a subject, and a captured image or a signal for generating the captured image that is acquired from an imaging device. The physiological information measurement apparatus includes a storage unit configured to store therein an electronic file, and a control unit configured to display at least one of the captured image and information of the vital sign on a display unit. At an image recording timing when an image recording instruction is provided, the control unit stores both the captured image and the information of the vital sign in the storage unit in an image format.

Physiological information measurement apparatus and physiological information system

Brain motion monitoring systems and methods are disclosed that can detect interpret and/or display normal and abnormal brain motions. The devices and methods can detect Cerebrovascular Stenosis and provide for Noninvasive Intracranial Pressure Measurement.

Method and apparatus to screen for and monitor cerebrovascular stenosis and for noninvasive intracranial pressure measurement

A physiological information system includes a patient monitor configured to acquire a vital sign based on a vital sign signal of a subject, and an ultrasonic measuring apparatus configured to acquire ultrasonic images based on ultrasonic waves transmitted toward the subject and received from the subject. The patient monitor includes a storage device configured to store measured data of the vital signs in association with measurement dates and times, and to store the ultrasonic images in association with image capture timings, and a controller configured to display a screen on a display section based on data, including the measured data and the ultrasonic images, stored in the storage device.

Patient monitor and physiological information system

The disclosed subject matter related to methods and apparatus for determining brain swelling and brain shifting in a patient as well as predicting a possible resultant increase in intracranial pressure in the patient. The apparatus can include a transducer such as an ultrasound transducer communicatively connected to a controller via wires or via wireless communications device(s). A monitor and/or alarm device can be provided to notify a practitioner when the controller has determined brain swelling is occurring and/or when an imminent increase in intracranial pressure is likely to occur.

Apparatus and methods for detecting increase in brain swelling and/or shifting

A patient monitor that acquires and displays first vital sign information and second vital sign information of a subject includes an event detection unit that is configured to detect an activation start event for starting an activation process of biological information processing software which performs a process pertaining to the second vital sign information and an activating event for activating the biological information processing software and a software control unit that causes the biological information processing software to be in a standby state, in which a part of the activation process of the biological information processing software has been performed, when the activation start event is detected by the event detection unit, and causes the biological information processing software to be in an active state from the standby state when the activating event is detected by the event detection unit.

Patient monitor, vital sign software control method, and program

A patient monitor that acquires a vital sign through a measurement sensor, and that is to be connected to an external measurement apparatus for measuring another vital sign, includes a master clock that is disposed in the patient monitor, and that manages common time information, a first operating system that manages first time information, and a second operating system that manages second time information, and that transmits and receives data to and from the external measurement apparatus. When a predetermined event occurs, the first operating system reads the common time information from the master clock, and updates the first time information. When the predetermined event occurs, the second operating system reads the common time information from the master clock, updates the second time information, and notifies the external measurement apparatus of the updated second time information or the common time information.
