Description

Image department film developing device

Technical Field

The invention relates to the field of medical instruments, in particular to a film developing device for an imaging department.

Background

The film processor is used for processing medical films such as X-ray films, CT, MPI, etc. The developing process of the developing machine mainly comprises four steps of developing, fixing, washing and drying, wherein a blank film is firstly soaked in developing liquor for a certain time, then soaked in fixing liquor for a certain time, then washed by clear water, and finally dried, and a finished product of the film is obtained. The traditional developing machine for the image department can not automatically feed the film, needs to manually feed the film, is easy to feed a plurality of films at one time, leads to the waste of the cards and the films, and influences the developing efficiency due to forced stop operation of the device. Conventional X-ray film processing machines operate with a film processing cycle (usually defined as a dry in/dry out process) that is typically over 90 seconds and slow.

In patent publication CN 204086805U, a developing device for imaging department is disclosed, which comprises a developing tank, a fixing tank, a cleaning tank, a drying box, a film box and a transmission part, wherein the transmission part is connected with a circular support plate. When the device is used, the blank films are clamped on the supporting plates, sequentially pass through the groove bodies, stay in the groove bodies for a period of time, and are correspondingly operated; the supporting plate holds a plurality of films which can be processed in different developing steps at the same time, but the processing can be smoothly carried out only under the condition that the time required by each developing step is consistent, and in fact, the time required by each developing step is different in most cases. Therefore, when the device is used for realizing the purpose of respectively regulating and controlling time for different film developing steps, the next film developing operation can be carried out only after the film developing operation of one film is finished, and the film developing efficiency is lower; in order to realize continuous film processing, the different times required by different film processing steps cannot be regulated, and the quality of the obtained film finished product is possibly not capable of meeting the requirements.
