This Application claims the benefit of Korean Patent Application No. 10-2008-0060384, filed on Jun. 25, 2008, the entire contents of which are incorporated by reference herein.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an ultrasonic diagnostic apparatus and, more particularly, to a portable ultrasonic diagnostic apparatus.
2. Description of the Related Art
Ultrasonic systems are one of the most widely applied and important diagnostic apparatus. In particular, since the ultrasonic system has characteristics of being non-invasive and non-destructive with respect to a target body, it has been widely used in the medical field. In recent years, a high performance ultrasonic system has been developed to generate two dimensional or three-dimensional interior images of the target body.
Since such an ultrasonic system has a very large size and a heavy weight, it must be secured to a particular location. Further, even in the case of a small size ultrasonic system, it generally has a weight of 10 kg or more, which makes it difficult to move or carry such a small size ultrasonic system. In order to overcome such disadvantages of the ultrasonic system, portable ultrasonic systems have been developed in the related art.
FIG. 1 is a perspective view of a conventional ultrasonic diagnostic apparatus.
Referring to FIG. 1, a conventional ultrasonic diagnostic apparatus 10 includes a body 11, a control panel 12, a display unit 13, and a probe 14.
The body 11 constitutes an outer appearance of the ultrasonic diagnostic apparatus 10 and is driven by power supplied from a battery received therein or from an external power supply.

Referring to FIGS. 2 to 5, the portable ultrasonic diagnostic apparatus 100 according to the first embodiment includes a body part 110, a handle 120, and a display unit 130.
The body part 110 constitutes an outer appearance of the ultrasonic diagnostic apparatus 100, and includes a body 112 and a pedestal 114.
The body 112 includes a beam former for transmit-focusing ultrasonic signals transmitted through a probe (not shown) and for receive-focusing ultrasonic signals received through the probe, a data creator for creating frame data based on the signals output from the beam former, a processor for generating a two-dimensional or three-dimensional interior image of a target body based on the frame data, a storage for storing data, a plurality of operating keys (reference number omitted) for driving the diagnostic apparatus 100 or for selecting functions thereof.
The pedestal 114 is disposed outside the body 112. The pedestal 114 is coupled to the handle 120. The pedestal 114 is provided with a coupling part 113 to which the handle 120 is rotatably coupled. The coupling part 113 has a curved through-hole shape such that the handle 120 can be inserted into and can penetrate the coupling part 113.
The handle 120 is coupled to the body part 110. The handle 120 has a curved shape, and preferably a circular shape. The handle 120 is inserted into the coupling part 113 configured to have the curved through-hole shape corresponding to the shape of the handle 120, so that the handle 120 is rotatably coupled to the pedestal 114.
Although the handle 120 is provided on the body part 110 to rotate 360 degrees, the handle 120 is rotated at a restricted angle since it is coupled to the display unit 130 described below.
The handle 120 can be rotated according to manipulation of an operator. For easy rotation of the handle 120, the body part 110 is configured to protrude below the handle 120.
Further, for more easy rotation of the handle 120, the coupling part 113 may be provided with a rolling member 115 that guides the rotation of the handle 120. Examples of the rolling member 115 include a ball bearing, a roller, and the like.
The display unit 130 is coupled to the handle 120 by a cylindrical hollow fastener 131. The display unit 130 serves to receive and display data and images processed by and sent from the body 112, and is electrically connected to the body 112 through a cable (not shown). Here, the cable connected to the display unit 130 can be connected to the body 112 through the handle 120.
The display unit 130 is coupled to the handle 120 to rotate up or down around the handle 120, so that the display unit 130 can rotate toward the body part 110 to cover the body part 110. The display unit 130 may be fixedly or separably coupled to the handle 120.
Next, operation and effects of the portable ultrasonic diagnostic apparatus 100 according to this embodiment will be described.
For the portable ultrasonic diagnostic apparatus 100 according to this embodiment, the handle 120 is used as a gripper when an operator carries the apparatus 100. In other words, when the operator carries the apparatus 100, the display unit 130 is rotated toward the body part 110 to allow the portable ultrasonic diagnostic apparatus 100 to be folded, and the handle 120 is gripped by the operator for carrying the apparatus 100. In this case, the handle 120 acts as the gripper of the apparatus 100.
Since the handle 120 has a curved shape, it improves close contact feelings with an operator's palm, so that the operator does not experience palm fatigue even after extended use.
The pedestal 114 may be provided with a securing part 116 that restricts rotation of the handle 120. The securing part 116 is configured to selectively restrict the rotation of the handle 120 according to manipulation of the operator. When carrying the ultrasonic diagnostic apparatus 100, the operator can stably carry the apparatus 100 by securing the rotation of the handle 120 by means of the securing part 116 to prevent the apparatus from shaking.
The securing part 116 may be formed in a variety of shapes. For example, the securing part 116 may be configured to restrict the rotation of the handle 120 by means of frictional interaction with the handle 120, or may be configured to restrict the rotation of the handle 120 by means of interaction with a plurality of protrusions formed on the handle 120. A detailed configuration of the securing part 116 can be variously realized by a person having ordinary knowledge in the art, and a detailed description thereof will be omitted herein.
The body part 110 may further include a track ball 118. The track ball 118 is disposed on a location relatively apart from the display unit 130 on the body part 110. For the portable ultrasonic diagnostic apparatus 100 of this embodiment, the handle 120 serves to support the operator's hand when the operator manipulates the track ball 118 or operating keys around the track ball 118. Accordingly, the portable ultrasonic diagnostic apparatus 100 of this embodiment can improve user convenience and reduce hand fatigue.
Further, for the portable ultrasonic diagnostic apparatus 100 of this embodiment, since the handle 120 is rotatably disposed on the body part 110, the display unit 130 coupled to the handle 120 can be rotated by the rotation of the handle 120.
When the operator rotates the handle 120, the display unit 130 rotates along with the handle 120 so that an angle of view of the display unit 130 also rotates. Thus, the operator can rotate the angle of view of the display unit 130 by rotating the handle 120.
With the handle 120 and the display unit 130 configured as described above, the portable ultrasonic diagnostic apparatus 100 of this embodiment enables the operator to view an image displayed on the front side of the display unit 130 simply by manipulating the handle 120 without inclining his or her body or head, even in the event where the operator carries out diagnosis on a patient with the body part 110 of the apparatus located in a diagonal direction with respect to the operator.
FIG. 6 is a perspective view of the portable ultrasonic diagnostic apparatus shown in FIG. 2, in which an assistant device is attached to the apparatus.
In FIG. 6, the portable ultrasonic diagnostic apparatus of this embodiment may further include an assistant device 140. The assistant device 140 may be, but is not limited to, an assistant display, Echo-Printer, a probe holder, a camera, and the like. The assistant device 140 is detachably coupled to the handle 120.
In addition to the aforementioned gripper function and the function of rotating the display unit 130, the handle 120 provides an attaching space for the assistant device 140. Accordingly, the portable ultrasonic diagnostic apparatus 100 of this embodiment allows an operator to attach the assistant device 140 and other accessories to the handle 120, so that the assistant device 140 and other accessories can be used or accommodated in the apparatus as needed.
