Description

TECHNICAL FIELD

[0001] The present application relates to the field of ultrasonic elastography pressure calibration device, and particularly relates to an ultrasonic elastography pressure calibration device. BACKGROUND

[0002] At present, ultrasonic elastography is a new ultrasonic diagnosis technology, which can study tumor and diffusion disease imaging that cannot be detected by traditional ultrasound, and can be applied to breast, thyroid, prostate and the like. The working principle of ultrasonic elastography is to compare the pressure data of elastic information before and after pressing the lesion site by using an ultrasonic probe. The basic principle of ultrasonic elastography is to help disease diagnosis by using the elasticity information of biological tissues: according to the different elasticity coefficients of various tissues, the strain is also different after external force or alternating vibration. Under the same external force, the strain caused by the larger elasticity coefficient is smaller, and vice versa. Ultrasonic elastography uses the difference in elasticity coefficient between tumor or other lesion regions and surrounding normal tissues to produce different strain sizes, which are displayed by color coding to determine the elasticity of the lesion tissue, so as to infer the possibility of certain lesions.

[0003] At present, the pressure calibration of the ultrasonic elastography equipment in the hospital needs to send the ultrasonic elastography equipment to be calibrated back to the manufacturer for calibration, which consumes time for the hospital and needs a self-operated calibration device.

[0029] Embodiment 1

[0031] As Figure 1 , Figure 2 and Figure 3As shown, the present invention discloses an ultrasonic elastography pressure calibration device, which includes: a body 1, four pressure calibration components 2 mounted on the body, the four pressure calibration components being combined into a whole and forming four quadrant regions, a pressure sensor being provided on the body, a phantom 4 being provided in each of the four pressure calibration components, the phantom having standard human tissue hardness, and a working area 3 being provided on the pressure calibration component located at the top, the working area being used to place an ultrasonic probe.

[0032] The pressure calibration component has a first mounting slot 5 at its upper part, which includes a first vertical slot 6 and a circular slot 7 installed at the bottom of the first vertical slot. A first conductive plate 8 is provided at the bottom of the first mounting slot, and the first conductive plate is connected to one pole of an external power supply via a wire. The pressure calibration component has a second mounting slot 9 at its lower part. The second mounting slot is adapted to the first mounting slot.

[0033] The second mounting slot is fitted with a detachable engaging component 10, which includes an upper cylinder 11. The bottom of the upper cylinder has an elastic bladder 12, within which multiple elastic skeletons are embedded to support outward expansion. An arc-shaped electrode plate 13 is located at the bottom of the elastic bladder. A movable electrode plate 14 is located inside the upper cylinder, with an electrorheological fluid located below it. A conductive spring 15 is located at the top of the movable electrode plate, and a second conductive plate 16 is located at the top of the conductive spring. A conductive part 17 is located at the top of the second mounting slot, connected to the other end of a power supply via a wire. A control switch 18 is also provided between the conductive part and the power supply.

[0034] In this embodiment, an ultrasonic probe is placed in the working area. The ultrasonic probe detects phantoms with different depths and elastic coefficients, and the detected data is transmitted to a pressure sensor. The accuracy of the ultrasonic probe is calibrated using the data from the pressure sensor.

[0035] When the locking component is installed into the second mounting slot, the second conductive sheet connects to the conductive part, and then the pressure calibration component located at the top is inserted into the pressure calibration component located at the bottom; the locking component is inserted into the first mounting slot, and the elastic bladder enters the circular groove of the first mounting slot through the vertical groove. Under the action of the conductive spring, the movable electrode sheet moves downward and pushes the liquid electrorheological fluid downward into the elastic bladder. At this time, the arc-shaped electrode sheet contacts the first conductive sheet. At this time, the movable electrode sheet, conductive spring, conductive part, first conductive sheet and arc-shaped electrode sheet are connected to the power supply. After the four sets of pressure calibration components are installed, the control switch is turned on and current is applied. The electrorheological fluid changes to solid, thereby preventing the pressure calibration components from falling off.
