Problems solved by technology

The current method is that the doctor uses a ruler to measure directly. This method has higher requirements on the doctor during operation. When the ruler cannot be kept parallel or vertical, the lesion cannot be located more accurately, and it is not convenient to monitor the patient's condition. analyze

Embodiment 1

[0024] Figure 1 ~ Figure 4 Schematically shows the liquid crystal film reading light with ruler of the present invention.

[0025] refer to figure 1 , a liquid crystal film reading lamp with a scale, including a frame 1, a luminescent plate 2 and a liquid crystal glass plate 3, a first control switch 4, a second control switch 5, a power switch 6, a bottom plate 7 and a light guide plate 8. The luminescent plate 2 and the liquid crystal glass plate 3 are fixed side by side in the frame 1 . The bottom plate 7 is fixed on one side of the frame 1 , the light guide plate 8 is fixed in the frame 1 , the luminous plate 2 is located between the bottom plate 7 and the light guide plate 8 , and the light guide plate 8 is located between the luminous plate 2 and the liquid crystal glass plate 5 . A plurality of LED light strips 21 are evenly arranged on the luminescent board 2, and the LED light strips 21 are controlled by an LED driver. The first control switch 4, the second contro...

Embodiment 2

[0031] A control method for a liquid crystal film reading lamp with a scale applied to Embodiment 1, comprising the following steps:

[0032] S1. Turn on the power switch 6 to energize the light-emitting board 2, and the white light emitted by the light-emitting board 2 penetrates the liquid crystal glass plate 3 to make the liquid crystal glass plate 3 display white; at this time, insert the film into the card slot 11 to make the film stick to the liquid crystal glass plate 3 outside, you can watch the film.

[0033] S2. When it is necessary to measure the length of the film, turn on the first control switch 4 to energize the first length measurement electrode group 341 and the second length measurement electrode group 342, so that the liquid crystal glass plate 3 displays the length measurement scale line;

[0034] When the first control switch 4 is turned on to energize the first length measurement electrode group 341 and the second length measurement electrode group 342, a...

Abstract

The invention discloses a liquid crystal film reading lamp with a ruler and a control method thereof. The liquid crystal film reading lamp comprises a frame, a light-emitting plate and a liquid crystal glass plate, wherein the light-emitting plate and the liquid crystal glass plate are fixed in the frame side by side, and the liquid crystal glass plate comprises a surface polaroid layer, a bottom polaroid layer, a liquid crystal layer, a first electrode layer and a second electrode layer; the liquid crystal layer is located between the surface polaroid layer and the bottom polaroid layer, the first electrode layer is located between the surface polaroid layer and the liquid crystal layer, the second electrode layer is located between the bottom polaroid layer and the liquid crystal layer, and the first electrode layer and the second electrode layer are each provided with a length measuring electrode set and an angle measuring electrode set. Measurement representation and the film viewer are fused, the TN type liquid crystal screen is used for displaying the length measurement scales and the angle measurement scales, two control switches are used for controlling display of length measurement and angle measurement respectively, a doctor does not need to find a measurement tool everywhere when reading a film and needing measurement, and the liquid crystal film reading lamp is convenient and fast to use and low in manufacturing cost.

Description

technical field [0001] The invention relates to a liquid crystal film reading lamp with a scale and a control method thereof, belonging to the technical field of medical auxiliary equipment. Background technique [0002] A reading light is a device used by clinicians to read imaging film. Fluorescent lamps or LED lamps are usually used to provide a uniform and stable light source for the reading plate. The light source passes through the black and white imaging film to increase its contrast, so as to achieve the function of assisting film reading. When the doctor reads the film, the size and angle changes of the anatomical structure are often one of the diagnostic basis. In order to judge the patient's condition more accurately, it is necessary to measure the length or angle of some parts on the film. For example, in the diagnosis of hip dysplasia in orthopedics, the angle between the vertical line of the center of the femur and the lateral edge of the acetabulum needs to b...
