Wireless power ultrasonic diagnostic apparatus

Abstract

The invention discloses a wireless power ultrasonic diagnostic apparatus, comprising a wireless transmitting unit, a wireless receiving unit and ultrasonic diagnostic equipment, wherein the wireless receiving unit is arranged in the ultrasonic diagnostic apparatus, and no wire is connected between the wireless transmitting unit and the ultrasonic diagnostic apparatus; the wireless transmitting unit comprises a transmitter device for converting drive current into electromagnetic wave to transmit, and the wireless receiving unit comprises a receiver device for receiving electromagnetic wave and converting the electromagnetic wave into induced alternating current via induction coils; and the transmitter device operates under a quasi-resonant state, the resonant frequency of the receiver device and the resonant frequency of the transmitter are the same, and the receiver device and the transmitter device operate under a resonace state. The invention provides a novel power supply mode for the traditional ultrasonic diagnostic apparatus to enable the traditional ultrasonic diagnostic apparatus to have wireless power supply and wireless charging functions, avoid constraint of numerous and complicated cables, and lead the movement and application of the apparatus to be more flexible, convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a wireless power supply ultrasonic diagnostic instrument. The ultrasonic diagnostic instrument has the functions of wireless power supply and wireless charging, frees from the shackles of complicated wires, and is more flexible and convenient to use. Background technique [0002] Ultrasound diagnosis is a non-invasive and cheap medical imaging diagnostic method, which is widely used in the inspection of various parts of the human body and animals, such as the inspection of abdominal organs and obstetrics and gynecology. However, the traditional ultrasonic diagnostic equipment must be equipped with a power cord, which needs to be connected to the power supply. When it needs to be moved to other places for use, the power cord must be unplugged in the prescribed order, and then the equipment must be moved to the required place. It is troublesome and error-prone, and the p...

However, the traditional ultrasonic diagnostic equipment must be equipped with a power cord, which needs to be connected to the power supply. When it needs to be moved to other places for use, the power cord must be unplugged in the prescribed order, and then the equipment must be moved to the required place. It is troublesome and error-prone, and the place where the device needs to be used must also have a power supply, otherwise it cannot be used. This power supply method greatly limits the places and areas where the device can be used, especially in some special occasions, such as During the earthquake relief, the disaster areas are generally damaged to varying degrees, and the normal power supply is usually not guaranteed, which makes the use of ultrasonic diagnostic equipment very inconvenient.

[0003] As we all know, in theory, according to the principle of electromagnetic field generation and propagation, the changing curren
