Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to an ultrasound diagnostic device and its power-on / off test circuit. Background Technology

[0002] Ultrasound waves are sound waves that are inaudible to humans. Due to their good directionality and strong penetrating power, they are often used for the diagnosis of diseases in biological tissues. Ultrasound diagnostic equipment is an essential instrument for diagnosing biological tissues using ultrasound waves. Ultrasound diagnostic equipment includes an ultrasound probe for transmitting and receiving ultrasound signals, a main unit connected to the ultrasound probe, and a display connected to the main unit.

[0003] The principle of ultrasound diagnostic equipment in diagnosing diseases in biological tissues is that an ultrasound probe emits ultrasound waves into the biological tissue. When the ultrasound waves encounter interfaces within the biological tissue, they are reflected and refracted, and may be absorbed and attenuated within the biological tissue. Since the morphology and structure of biological tissues are different, the intensity of the reflected ultrasound signals varies. The ultrasound probe receives the ultrasound signals reflected back from the biological tissue and transmits them to the main unit of the ultrasound diagnostic equipment. The main unit processes the ultrasound signals to obtain ultrasound images of the biological tissue and displays the ultrasound images on a monitor. Doctors can then use the ultrasound images to determine whether there are lesions in the biological tissue, thereby diagnosing diseases in the biological tissue.

[0004] To ensure the stability of ultrasound diagnostic equipment, manufacturers need to perform power-on and power-off tests on the equipment before it leaves the factory. These tests are typically conducted manually, but this method is time-consuming and unreliable, failing to adequately verify the equipment's stability. Summary of the Invention

[0005] The purpose of this application is to overcome the shortcomings of the existing technology, which usually uses manual power-on and power-off methods when testing the power-on and power-off of ultrasound diagnostic equipment. However, manual power-on and power-off is not only time-consuming but also unreliable and cannot fully verify the stability of ultrasound diagnostic equipment.

[0006] Therefore, this application provides a power-on / off test circuit for an ultrasound diagnostic device, including a central processing unit (CPU), an external user interface connected to the CPU, and a first switch for controlling the power-on and power-off of the ultrasound diagnostic device. A control switch is provided between the external user interface and the CPU. One end of the control switch is connected to the external user interface, and the other end of the control switch is connected to the CPU or the first switch. When the external user interface receives a control signal to control the first switch to turn on and off, the control switch is connected to the first switch to control the first switch to turn on and off according to a preset time interval. When the external user interface does not receive a control signal to control the first switch to turn on and off, the control switch is connected to the CPU.

[0007] Furthermore, a control signal for controlling the opening and closing of the first switch is sent to an external user interface via a test fixture. The test fixture includes a first control element and a relay connected to the first control element. The first control element is used to control the relay to close in order to transmit the control signal for controlling the opening and closing of the first switch to the external user interface.

[0008] Furthermore, the first control element is a microcontroller.

[0009] Furthermore, a second control element is connected between the first switch and the central processing unit. The second control element is used to send control signals to the central processing unit to control the ultrasound diagnostic equipment to turn on and off under the control of the first switch.

[0010] Furthermore, the second control element is a microcontroller.

[0011] Furthermore, the control switch is a USB signal switching switch.

[0012] Furthermore, the power-on / off test circuit also includes a controller for controlling the test fixture, the controller having a computer program for controlling the test fixture.

[0013] Furthermore, the controller is a computer.

[0014] Furthermore, the first switch is a push-button switch or a touchscreen switch.

[0015] This application also provides an ultrasound diagnostic device, which includes the power-on / off test circuit of the aforementioned ultrasound diagnostic device.

[0016] The power-on / off test circuit of the ultrasound diagnostic equipment disclosed in this application can input control signals to the control switch via an external user interface to control the opening and closing of the first switch. Under the action of the control signals, the first switch opens and closes according to a preset time interval to realize the automatic power-on and power-off of the ultrasound diagnostic equipment, thereby realizing the automatic power-on / off test of the ultrasound diagnostic equipment. Compared with manual power-on / off, this greatly saves the power-on / off test time and improves the reliability of the power-on / off test, and can fully verify the stability of the ultrasound diagnostic equipment.

[0027] Example 1

[0028] Reference Figures 1-3 Embodiment 1 of this application provides a power-on / off test circuit for an ultrasound diagnostic device, including a central processing unit 1, an external user interface 2 connected to the central processing unit 1, and a first switch 3 for controlling the power-on and power-off of the ultrasound diagnostic device. A control switch 4 is provided between the external user interface 2 and the central processing unit 1. One end of the control switch 4 is connected to the external user interface 2, and the other end of the control switch 4 is connected to either the central processing unit 1 or the first switch 3. When the external user interface 2 receives a control signal to control the first switch 3 to open and close, the control switch 4 is connected to the first switch 3 to control the first switch 3 to open and close according to a preset time interval. When the external user interface 2 does not receive a control signal to control the first switch 3 to open and close, the control switch 4 is connected to the central processing unit 1.

[0029] The aforementioned power-on / off test circuit for the ultrasound diagnostic equipment can input control signals to the control switch 4 via the external user interface 2 to control the opening and closing of the first switch 3. Under the action of the control signals controlling the opening and closing of the first switch 3, the first switch 3 opens and closes according to a preset time interval to realize the automatic power-on and power-off of the ultrasound diagnostic equipment, thereby realizing the automatic power-on / off test of the ultrasound diagnostic equipment. Compared with manual power-on / off, this greatly saves the power-on / off test time and improves the reliability of the power-on / off test, and can fully verify the stability of the ultrasound diagnostic equipment.

[0030] In some embodiments, the test fixture 5 sends a control signal to the external user interface 2 to control the opening and closing of the first switch 3, referring to... Figure 2 and Figure 3 The test fixture 5 includes a first control element 51 and a relay 52 connected to the first control element 51. The first control element 51 controls the relay 52 to close, transmitting control signals to the external user interface 2 to control the opening and closing of the first switch 3. The test fixture 5 transmits the control signals to the external user interface 2 to control the opening and closing of the first switch 3. After receiving the signals, the external user interface 2 transmits them to the control switch 4. After receiving the control signals to control the opening and closing of the first switch 3, the control switch 4 connects to the first switch 3 to control the opening and closing of the first switch 3 according to a preset time interval, thereby realizing the automatic power-on and power-off of the ultrasound diagnostic equipment.

[0031] Specifically, external user interface 2 is a USB interface. When external user interface 2 does not receive a control signal to control the first switch 3 to turn on or off, control switch 4 is connected to the central processing unit 1 by default (see reference). Figure 1 External user interface 2 is used for data transmission and connection between the ultrasound diagnostic equipment and external devices. When external user interface 2 is connected to test fixture 5 (refer to...), Figure 3 When the test fixture 5 starts transmitting control signals, the external user interface 2 transmits the control signals for opening and closing the first switch 3 through the control switch 4 to the first switch 3, thereby controlling the first switch 3 to open and close according to the preset time interval.

[0032] Specifically, the first control element 51 is a microcontroller. Of course, the first control element 51 can also be other components capable of controlling the closing of the relay 52. ​​When the relay 52 is closed, the first control element 51 can transmit control signals to the external user interface 2 to control the opening and closing of the first switch 3. Specifically, the first switch 3 can be a push-button switch or a touch screen switch, or it can be a voice input switch.

[0033] In some embodiments, a second control element (not shown in the figure) is connected between the first switch 3 and the central processing unit 1. The second control element is used to send control signals to the central processing unit 1 to control the ultrasound diagnostic equipment to turn on and off under the control of the first switch 3. Specifically, the second control element is a microcontroller. After receiving the control signal to control the first switch 3 to turn on and off, the first switch 3 transmits the control signal to the second control element, which then transmits the control signal to the central processing unit 1, thereby controlling the ultrasound diagnostic equipment to turn on or off through the central processing unit 1.

[0034] In some embodiments, refer to Figures 1-3The power-on / off test circuit of the ultrasound diagnostic equipment also includes a controller 6 for controlling the test fixture 5. The controller 6 contains a computer program for controlling the test fixture 5. Specifically, the controller 6 is a computer, and the computer program controlling the test fixture 5 can control the test fixture 5 to input control signals to the external user interface 2 to control the opening and closing of the first switch 3. The computer program can also set the time interval between the opening and closing of the first switch 3.

[0037] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
