Film-observing and vision-testing two-in-one lamp box

Abstract

The invention relates to the technical field of medical instruments, and concretely relates to a film-observing and vision-testing two-in-one lamp box. The box, which can be used for observing a ray negative film and also for testing vision, includes a frame and a lamp box. The lamp box is fixedly disposed on the frame through an overturning shaft, and can overturn 360 degrees around the overturning shaft. An LED light-emitting plate is disposed in the lamp box. The periphery of the lamp box is made of a metal aluminium substrate, and the four sides of the lamp box are made from acrylic plates. A visual chart is printed on the surface of a rear panel of the lamp box. Compared with the prior art, the film-observing and vision-testing two-in-one lamp box has the advantages that a film-observing lamp and a visual chart are combined on the lamp box, the structure is reasonable, and purchase costs for hospitals are saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a two-in-one light box for visual acuity and visual acuity observation, which can be used for observing radiographic negatives and measuring visual acuity. Background technique [0002] At present, in medical imaging examination, the film viewer is generally used to observe the radiographic film to obtain the diagnosis result. Nowadays, the film viewer used in the hospital has a single function and can only play the role of observing the radiographic film. As we all know, the eye chart is currently commonly used in hospitals and schools. It is a kind of eyesight testing tool, and can also use the light box, the function is often relatively single, and can only be used to measure eyesight. [0003] And because the existing film viewing lamp is often fixed and prevented in the doctor's office, this is to make the observation of radiographs need to be carried out in a specif...

[0002] At present, in medical imaging examinations, the film viewer is generally used to observe the radiographic film to obtain the diagnosis result. Nowadays, the film viewer used in the hospital has a single function and can only play the role of observing the radiographic film. As we all know, the eye chart is currently commonly used in hospitals and schools. A vision testing tool, and can also be used to light boxes, the function is often relatively simple, can only be used to test vision

[0003] And because the existing film viewing lamp is often fixed and prevented in the doctor's office, this is to make the observation of radiographs need to be carried out in a specific doctor's office where the film viewing lamp is installed, and the film cannot be viewed at any time according to the actual situation at will, which will delayed diagnosis
