Method for reducing requirements of medical diagnostic X-ray apparatus on power supply capacity

Abstract

The invention discloses a method for reducing requirements of a medical diagnostic X-ray apparatus on power supply capacity, and belongs to the field of medical apparatus. The method comprises the following steps: setting an electric energy storage module and a charging module at the power supply input end of an inverted power supply module, and carrying out on-line continuous electric energy supplement on the electric energy storage module in a mode of 'float charging'; and setting a voltage comparing / monitoring module which is used for detecting the output voltage of the electric energy storage module or the input voltage of the inverted power supply module and provide interlocking control conditions for the startup of the inverted power supply module. The method avoids the adverse effect on normal operation and service life of the medical diagnostic X-ray apparatus caused by insufficient capacity and unstable quality of the single-phase civil power supply; the application range of the medical diagnostic X-ray apparatus is greatly expanded; preconditions are created for using small and medium-sized medical diagnostic X-ray apparatus in medical health centers or stations or spots; the method can be widely used in the fields of design and manufacture of the small and medium-sized medical diagnostic X-ray apparatus with the specifications lower than 400 mA.

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
