Ultrasonic diagnostic apparatus having a patient-use monitor

Abstract: An ultrasonic diagnostic apparatus uses an ultrasonic wave to obtain information on the inner state of a human body without conducting a surgical operation on the patient. The ultrasonic diagnostic apparatus includes a receiving recess (12) so that a patient-use monitor (40) can be connected with and disconnected from a main body (10). Diagnostic results measured in the main body (10) are displayed on the patient-use monitor (40) including a support shaft (44) which can be inserted into the receiving recess. Thus, the patient can see his or her diagnostic results easily. Since the patient-use monitor (40) is compatible with other types of ultrasonic diagnostic apparatuses having each receiving recess installed in the main body, the patient-use monitor can be used in other types of the ultrasonic diagnostic apparatuses.

Description: BACKGROUND OF THE INVENTION The present invention relates to an ultrasonic diagnostic apparatus, and more particularly, to an ultrasonic diagnostic apparatus having a patient-use monitor mounted at the side of a body of the ultrasonic diagnostic apparatus, in order to make a patient see his or her diagnostic results easily. In general, an ultrasonic diagnostic apparatus uses an ultrasonic wave to obtain information on the inner state of a human body without having a surgical operation with respect to the patient. The ultrasonic diagnostic apparatus emits an ultrasonic wave into a human body, analyzes a reflected wave from the human body, and displays information on the human body on a monitor. A monitor for displaying human body information thereon is positioned in front of an operator in order to have the operator facilitate to watch the monitor. As a result, the patient cannot see his or her diagnostic results during the operator's diagnosis. In the case where the patient wishes to see his or her diagnostic results, the operator should turn the monitor to the direction of the patient's visibility. As an alternative for enabling a patient to see his or her diagnostic results, there is a method for installing a subsidiary monitor in the visible area in which the patient can see it in addition to a main monitor for enabling an operator to monitor the human body of the patient. However, a support for supporting a subsidiary monitor is needed to install the subsidiary monitor in addition to a main monitor placed on top of the main body of the ultrasonic diagnostic apparatus. Thus, such a support requires a more space for supporting a monitor, and movement of the subsidiary monitor inconveniences an operator. EP 520,338 relates to an ultrasound imagining system and method for controlling the system having a control panel which includes in menu items divided into system mode the new items for selecting a system mode and control set in menu items for selecting functions corresponding to a selected system mode menu item; the system comprising also a display for displaying the ultrasound image generated by the system. USP 5,415,287 relates to an endoscope holding and a storing apparatus which catches and holds an endoscope on an endoscope system storage rack or a system card and which makes transportation of an used endoscope easier. The endoscope system comprises a monitor part positioned on a pillar member and has a main monitor which is mounted on the monitor term base; further it comprises a nurse monitor and a patient monitor on the said surface on the upper part of the pillar member. The nurse monitor and patient monitor are provided with a hook and can be held by the hook itself located on the upper part of the pillar member. SUMMARY OF THE INVENTION To solve the above problems, it is an object of the present invention to provide an ultrasonic diagnostic apparatus which is compatible with other types of ultrasonic diagnostic apparatuses, in which a compact subsidiary monitor for a patient's use which is constructed as a liquid crystal panel is detachably installed in any part of the main body. To accomplish the above object of the present invention, there is provided an ultrasonic diagnostic apparatus including a main body (10) in which a conversion circuit for converting an ultrasonic echo signal received from a probe into a video signal is installed, and a main monitor (20) for displaying the video signal thereon, the ultrasonic diagnostic apparatus characterized in that it comprises: a receiving recess (12) formed at the main body (10), for housing a patient-use monitor (40); and a patient-use monitor (40) including a support shaft (44) which is adapted to be connected with and disconnected from the receiving recess (12); and a display for displaying a video signal applied from the main body (10). BRIEF DESCRIPTION OF THE DRAWINGS The preferred embodiment is described with reference to the drawings wherein: Fig. 1 is a perspective view of an ultrasonic diagnostic apparatus having a patient-use monitor according to a preferred embodiment of the present invention; and Fig. 2 is a side view of the apparatus shown in Fig. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In Figs. 1 and 2 showing an ultrasonic diagnostic apparatus having a patient-use monitor according to a preferred embodiment of the present invention, the ultrasonic diagnostic apparatus includes a main body 10 housing therein a circuit for converting an ultrasonic echo signal input from a probe (not shown) into a video signal to be displayed, and a main monitor 20 for displaying the video signal thereon. The main monitor 20 is connected to the main body 10, and usually placed in front of an operator in order to enable the operator to monitor the state of a patient. The main monitor 20 can be rotated so that the operator can see diagnostic results at various angles of view. A key manipulator board 30 needed for diagnosis is located on the top-front of the main body 10. A receiving recess 12 for a patient-use monitor 40 is formed at the side of the main body 10. Since the patient is usually located at the side of the ultrasonic diagnostic apparatus, it is preferable that the receiving recess 12 to be connected with/disconnected from the patient-use monitor 40 is formed at the side of the main body 10. The patient-use monitor 40 according to the present invention includes a display 42 for displaying an image applied from the main body 10 and a rod-shaped support shaft 44 which is inserted into the receiving recess 12 of the main body 10. In this embodiment of the present invention, a compact liquid crystal monitor can be used as the display 42. The patient-use monitor 40 includes a video signal input port (not shown) for receiving a video signal applied from the main body 10. The main body 10 and the video signal input port are connected to each other via a predetermined video signal transmission cable. Also, the patient-use monitor 40 includes a power input port (not shown) via which power is supplied from the main body 10.. Otherwise, power can be supplied to the patient-use monitor 40 via an adapter connector from an external source. Also, the display 42 can be rotated around the fixed support shaft 44. The ultrasonic diagnostic apparatus according to the present invention is compatible with other types of ultrasonic diagnostic apparatuses including each receiving recess 12 for housing a support shaft 44 of a patient-use monitor 40. Thus, the video signals applied from other types of the ultrasonic diagnostic apparatuses can be displayed on the patient-use monitor 40. Also, the patient-use monitor 40 can use other kinds of monitors as well as the above-described liquid crystal monitor. It is also more preferable that the patient-use monitor 40 can be easily moved and is compact and light. As described above, the ultrasonic diagnostic apparatus according to the present invention provides an ultrasonic diagnostic apparatus having a patient-use monitor which is detachable from a main body and enables a patient to see the diagnostic results easily. Since the patient-use monitor of the present invention can be connected with and disconnected from the other types of ultrasonic diagnostic apparatuses having each receiving recess formed on the main body, the patient-use monitor can be used by being connected with other types of the ultrasonic diagnostic apparatuses. The invention has been described with certain embodiments for illustrative purpose only without limiting the invention.
