Problems solved by technology

Due to discarding part of the data, the light and dark details of the image will be lost, which will affect the quality of the formed image, and then the information provided by the formed image will be wrong, which will affect the accuracy of medical diagnosis.
[0010] At present, in the slit lamp, the control handle and the imaging control device respectively control the position of the objective lens 1 and the imaging moment and time; in operation, the control handle can enable the observer to observe images at multiple positions, and the observer needs to check the images at the corresponding positions When saving, it is necessary to control the image collector through the imaging control device to collect and save the images in the predetermined area; in this way, during the operation, the observer needs to control the two parts of the control handle and the imaging control device. Makes the control operation of the slit lamp very inconvenient

Abstract

The invention discloses a slit lamp and an information management system thereof. The information management system comprises an image control device, an image processing device and a patient information management device. The patient information management device comprises a storage module and an information maintenance module connected with each other and further comprises a call trigger device and a call submodule. The call trigger device sends a call instruction to one of the image control device, the image processing device and the patient information management device. When the call instruction sent by the call trigger device to the image processing device is triggered, the call instruction is sent to the call submodule. The call submodule sends an image call instruction to the information maintenance module. The information maintenance module stores images, output from an imaging device, in a storage module in the preset way and calls a preset image stored in the storage module. The information management system can be used to control imaging, process images and manage patients' information, so that operation of the slit lamp is more facilitated, and operating efficiency is improved.
