A Method for Reducing the Power Capacity Requirement of Medical Diagnostic X-ray Machine

Abstract

The invention relates to a method capable of reducing the power supply capacity requirement of a medical diagnostic X-ray machine, which belongs to the field of medical equipment. At the power input end of the inverter power supply module, an electric energy storage module and a charging module are set up to supplement the electric energy storage module online and continuously in the working mode of "floating charging"; a voltage comparison / monitoring module is set up to use It is used to detect the output voltage of the electric energy storage module or the input voltage of the inverter power module, and provide interlock control conditions for starting the inverter power module. It solves the adverse effects of insufficient capacity and unstable quality of single-phase civil power supply on the normal operation and service life of medical X-ray diagnostic equipment, greatly expands the scope of application of medical diagnostic X-ray machines, and provides medical and health services in rural areas. Create prerequisites for the use of medium and small medical diagnostic X-ray machines at all / stations / points. It can be widely used in the field of design and manufacture of medium and small medical diagnostic X-ray machines with specifications below 400mA.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a power supply device for a medical diagnostic X-ray machine. Background technique [0002] X-ray diagnostic devices refer to fixed devices that use the characteristics of X-rays to transmit images through the human body to diagnose diseases. They can be roughly divided into several categories such as X-ray diagnostic machines and X-ray CT machines. [0003] According to the general classification of medical equipment, X-ray machines with specifications of 400mA (referring to the output current of its high-voltage system) and above are defined as large-scale X-ray diagnostic machines (some materials introduce specifications of 500mA and above as large-scale X-ray diagnostic machines). [0004] In the "Code for Electrical Design of Civil Buildings (JGJ / T 16-92)", it is stipulated that for large-scale X-ray diagnostic machines, a special circuit should be provided for power supply. ...

AI Technical Summary

Problems solved by technology

[0014] The technical problem to be solved by the present invention is to provide a method that can reduce the power supply capacity requirements of medical diagnostic X-ray machines, which solves the problems of the normal operation of medical X-ray diagnostic equipment due to insufficient power supply capacity and unstable quality of ordinary single-phase civilian power supplies. The adverse effect brought by the service life has greatly expanded the scope of application of medical diagnostic X-ray machines, creating prerequisites for the use of small and medium-sized medical diagnostic X-ray machines in rural medical and health centers / stations / points
