Description

Supporting apparatus for arm for ultrasound examination

The present invention relates to an arm support device for ultrasound examination, and more particularly, by supporting the arm of a doctor who has to maintain an arm posture for a long time by holding a probe during ultrasound examination, thereby solving the discomfort of the arm caused by gravity. It relates to an arm support device for ultrasound examination, which can increase the efficiency of the ultrasound examination and reduce unnecessary physical contact with people to be measured.

2. Description of the Related Art In general, an ultrasound diagnosis apparatus irradiates an ultrasound signal from a body surface of a subject to be measured toward a desired part of the body, and obtains an image of a tomography or blood flow of a soft tissue non-invasively using information of the reflected ultrasound signal.

Such an ultrasound diagnosis apparatus includes a control panel including a cart-shaped body accommodating main components of the apparatus, a probe for transmitting and receiving ultrasound, various switches and keys for inputting commands required for operation of the apparatus, and an ultrasound diagnosis result. It is configured to include a display for implementing an image.

At this time, the doctor holds the probe in one hand and moves the probe in contact with the subject to be measured in order to perform ultrasound diagnosis on the subject to be measured using such an ultrasonic diagnostic device, and operates the control panel with the other hand to perform ultrasonic diagnosis. The results obtained by the ultrasound diagnosis are displayed as images through the display.

Meanwhile, during the ultrasound examination, the doctor holds the ultrasound probe with one hand and touches the area to be examined for a certain period of time to image it. For this purpose, it is necessary to maintain the abduction state of the arm holding the ultrasound probe.

Accordingly, in the related art, as an example of a technique for supporting a doctor's arm during an ultrasound examination, Korean Patent Registration No. 10-2067070 discloses a stand installed on one side of a bed on which a patient is lying for ultrasound measurement, a patient lying on the bed. For ultrasound measurement, it includes a pedestal that allows the arm of a doctor holding an ultrasound probe to be mounted, and a joint drive unit that is connected between the stand and the pedestal and adjusts the angle according to the movement of the arm joint of the doctor mounted on the pedestal. A multi-purpose ultrasonic probe holder device has been disclosed.

However, since the conventional ultrasonic probe holder has a structure that is fastened to the bed, it is cumbersome or difficult to move the position corresponding to the position of the subject to be measured and various examination sites, and it cannot support the arm stably and the arm is comfortable. There was a problem that it was difficult to maintain the posture.

The air pump unit 624 is driven and controlled according to the pressure value received from the .

Hereinafter, a control method of the controller 700 will be described.

By receiving data values from the above-described distance sensing sensor 810, the scanning module 830 and the selection panel 840, the position change unit 900, the height adjustment unit 300 and the length adjustment unit 500 are driven and controlled. The position of the support unit 600 is positioned at the set position, and the arm is stably fixed by driving and controlling the air pump unit 624 through the pressure value received from the pressure sensor 820 .

Specifically, when the operation of the scanning module 830 starts, the scanning module 830 transmits the initial position data of the support unit 600 for the measurement target to the control unit 700 .

Then, the control unit 700 compares the initial position of the support unit 600 received from the scanning module 830 with the distance value received from the distance sensor 810, and the initial position of the support unit 600 and the received According to the distance value, the lifting motor 310 (Z-axis movement) and the length adjustment motor 510 (X-axis movement) are driven and controlled so that the support part 600 is positioned at a position set for the person to be measured to control the support part 600 ) is moved.

In this way, when the Z-axis movement and X-axis movement of the support unit 600 are made, the control unit 700 receives the set ultrasound measurement site (position) received from the selection panel 840, and sets the neck or abdomen of the subject to be measured. The position control motor 910 is driven and controlled so that the support unit 600 is moved to the ultrasonic measurement site.

In other words, the control unit 700 compares the position of the support unit 600 with respect to the measurement target through the scanning module 830 and the ultrasonic measurement portion received from the selection panel 840, and the support unit 600 is set. The position change unit 900 is driven and controlled to move to the ultrasonic measurement site.

When the movement of the position of the support unit 600 is completed as described above, the doctor inserts the arm into the air pocket unit 623 and turns on the arm fixing means 620 in the selection panel 840, Accordingly, the control unit 700 drives the air pump unit 624 according to the operation signal of the arm fixing means 620 received from the selection panel 840 to inflate the air pocket unit 623 . At this time, when the pressure value received from the pressure sensor 820 in driving the air pump unit 624 becomes the set pressure value, the control unit 700 stops the operation of the air pump unit 624 to prevent the air pocket unit 623 from being driven. Do not apply excessive pressure on your arm.

Although the present invention has been described with reference to the embodiment shown in the drawings, which is merely exemplary, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
