Description

Rotating notebook ultrasonic diagnostic device

This application claims the priority of the Chinese Patent Application filed on August 6, 2007, the Chinese Patent Office, the application number is 200720124930.3, and the utility model name is "display-rotatable notebook type B-ultrasound", the entire contents of which are incorporated by reference. In this application.

Technical field

The invention relates to the field of medical instruments, in particular to a notebook ultrasonic diagnostic apparatus with a display screen rotatable.

Background technique

The notebook type ultrasonic diagnostic apparatus is an ultrasonic examination and diagnosis instrument commonly used by medical institutions, and is one of the three routine inspection equipments indispensable for hospitals, and is widely used for clinical examination and diagnosis of human organs. The principle is that according to the different density and different ultrasonic propagation speeds of different human tissues and organs, that is, the characteristics of different acoustic impedances (the product of medium density and sound velocity), the piezoelectric wafers are excited by a certain regular electric pulse (transformation) The ultrasonic wave (sound energy) is injected into the human body, and the reflected echo is generated through the interface of different organs in the body; the echoes of different sizes reflected by the original transmitted ultrasonic wave are transposed The device accepts, thereby converting the received echo (acoustic energy) into an electrical pulse, which is processed by digital beam synthesis and digital scan conversion to form a signal image or a Doppler blood flow image.

Referring to FIG. 1 , the existing notebook ultrasonic diagnostic apparatus generally includes a display screen 101 and a main body 102 with an operation panel (hereinafter referred to as a bottom), and the display screen and the bottom are hinged, and can be opened and closed. . When the operator uses the ultrasonic diagnostic apparatus, it is usually placed on the operation table smoothly, the display screen is turned on, and then the probe connected to the notebook ultrasonic diagnostic apparatus is held, and the different parts of the patient are swam away while watching the display screen. Record and analyze data. In this process, because the operator is easy to explore It is usually necessary to move or change its position, and the orientation of the display is fixed. It is difficult to watch when the angle is too biased. This makes it inconvenient for the operator to record or analyze the data, so that the operator cannot obtain the data in real time. Good detection. Of course, when detecting, the operator or others can move the base to change the orientation of the display to facilitate reading data. However, the ultrasonic diagnostic equipment is a precision instrument that requires safe and stable placement, especially when performing detection. It is not allowed to move at random, that is, the mobile operator has to move back to the seat; plus the four contact magnets on the bottom of the ultrasonic diagnostic apparatus, it is extremely inconvenient to move, which seriously affects the efficiency and accuracy of detection.
