Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment technology, specifically a medical image viewing device. Background Technology

[0002] Medical imaging viewing devices are indispensable equipment for doctors in disease diagnosis. Traditional viewing lights typically consist of a light box, a light source, and a transparent viewing screen. During use, doctors must manually attach or attach the film to the viewing screen. This method has several drawbacks: First, the film is not securely fixed and is prone to slipping or shifting, especially when comparing multiple films simultaneously; second, manual film placement makes it difficult to ensure precise alignment each time, affecting observation efficiency; third, traditional light sources are mostly fluorescent tubes, which suffer from uneven brightness, high heat generation, high energy consumption, and short lifespan, and brightness adjustment is not flexible enough. Furthermore, some viewing lights lack intelligent prompts indicating whether the film is properly placed, which may lead to misjudgments in complexly lit viewing rooms. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of unstable film fixation, easy slippage or displacement, which is especially inconvenient when multiple films need to be compared at the same time. Manually placing the film makes it difficult to ensure accurate alignment every time, affecting observation efficiency. Traditional light sources are mostly fluorescent tubes, which have problems such as uneven brightness, high heat generation, high energy consumption and short life. In view of the above problems, this invention provides a medical image viewing device.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a medical image viewing device, a viewing device, a support base, and an adjustment bracket connecting the viewing device and the support base. The viewing device includes a housing, inside which a light source module is provided for providing uniform backlight to an observation screen. The observation screen is mounted on the front end of the light source module and is used to hold medical image films. A cover is fixed to the side of the housing by bolts. An observation window is provided on the end face of the cover. The position of the observation window corresponds to the observation screen. A gap groove is formed between the inner side of the observation window and the front face of the observation screen for inserting medical image films.

[0005] Furthermore, the housing also includes a clamping device, a control panel, and a light source control panel. The clamping device has a square frame structure and is arranged around the periphery of the viewing screen for fixing medical imaging films. The control panel is used to operate the overall functions of the viewing device, and the light source control panel independently controls the switching on and off and brightness adjustment of the light source module.

[0006] Furthermore, the clamping device includes a base frame, a clamping strip, and a cover plate. The clamping strip is clamped onto the upper surface of the base frame, and the cover plate covers the base frame and presses and fixes the clamping strip, thereby realizing a double-layer fixing structure for the clamping strip.

[0007] Furthermore, the inner side of the clamping strip is provided with an insertion groove that bends inward on both sides, and a clamping piece is provided at the opening of the insertion groove. The clamping piece is made of nylon material and is used to provide a tight and flexible bonding pressure when the film is inserted.

[0008] Furthermore, a plurality of infrared sensors are installed on the inner side of the cover plate. There are eight infrared sensors in total, arranged in groups of two on the four edge areas of the inner side of the cover plate, for detecting whether the medical imaging film is inserted in place.

[0009] Furthermore, the light source module includes multiple LED light strips arranged side by side and a diffuser plate. The diffuser plate is located between the LED light strips and the observation screen to ensure uniform light distribution and prevent the formation of bright spots or dark areas on the observation screen.

[0010] Furthermore, the width of the gap groove gradually narrows inward from the opening end in the insertion direction, and its two side walls form guiding slopes to provide guidance during film insertion and achieve initial alignment of the film.

[0011] Furthermore, the control panel and the light source control panel are integrated in the same operating area of ​​the housing. The control panel also includes an input interface for connecting external imaging devices and a switching button for adjusting the display mode of the observation screen. Beneficial effects

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a dedicated gap groove formed between the cover and the observation screen, allowing users to easily insert film as if inserting a document, making the operation intuitive and simple.

[0013] 2. In the clamping device of this invention, a rubber strip with an inwardly curved insertion groove and a nylon clamping piece is used, which provides flexibility and tight fixing force while avoiding scratching the film. The narrowing design of the gap groove further guides the film to precise alignment.

[0014] 3. The light source module of this invention uses LED light strips in conjunction with a diffuser plate, which effectively eliminates the problems of bright spots and dark areas in traditional light sources, provides highly uniform backlight, and LED light sources have the advantages of adjustable brightness, energy saving, and long lifespan.

Detailed Implementation

[0022] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0023] like Figure 1 As shown, the medical image viewing device provided by the present invention mainly includes a support base 1, an adjustment bracket 2, and a viewing device 3. The adjustment bracket 2 can be a gas spring or a mechanical spring arm to realize flexible adjustment of the viewing device 3 in height, angle, and rotation direction to adapt to the viewing habits of different doctors.

[0024] like Figure 2 As shown, the core of the viewing device 3 is the housing 31. Inside the housing 31, at the rear, there is a light source module 32. This module consists of multiple parallel LED light strips and a diffuser plate 35 located in front of it. The diffuser plate 35 can scatter the point or line LED light to form a uniform surface light source. An observation screen 33 is fixedly installed in front of the light source module 32. It is usually a frosted acrylic plate with high light transmittance and is used to carry and transmit images.

[0025] A cover 34 is bolted to the right end of the housing 31. An observation window 343 is opened on the cover 34, which is slightly smaller than the observation screen 33. A certain space is maintained between the inner wall of the observation window 343 and the front surface of the observation screen 33, forming a gap groove 344 with an opening at the top. The film is inserted through this opening along the gap groove 344.

[0026] like Figures 3 to 5 As shown, a square clamping device 311 is installed on the housing 31 around the observation screen 33. The device consists of a base frame 3111, a clamping strip 3112, and a cover plate 3113. The clamping strip 3112 is inserted into the groove of the base frame 3111 and then fixed by the cover plate 3113 with screws to ensure that the strip will not come loose. The inner side of the clamping strip 3112 has a unique structure. Its main body is an insertion groove 3114 formed by bending inward on both sides. The opening is provided with a soft nylon clamping piece 3115. When the film is inserted from the gap groove 344 and continues to be pushed towards the clamping device 311, the edge of the film will open the clamping pieces 3115 on both sides and slide into the insertion groove 3114. Due to the elastic recovery force of the nylon material, the clamping pieces 3115 will generate a continuous, uniform and gentle clamping force on both sides of the film, thereby achieving reliable fixation without damaging the film.

[0027] like Figure 6 As shown, on the inside of the cover plate 3113 facing the film, two infrared sensors 3116 are installed along each of the four sides. When the film is fully inserted, its edges will simultaneously block the sensors, and the system will determine that the film has been placed correctly. The sensor signal can be connected to the control circuit to trigger the indicator light to light up or to emit a prompt sound.

[0028] like Figure 2 As shown, the width of the gap groove 344 gradually narrows from the opening inwards, forming a guide slope. This design can correct and guide the film at the initial stage of insertion, making it easier to align and enter the clamping range of the clamping device 311.

[0029] In use, the doctor turns on the light source and inserts the film through the opening of the gap groove 344. Under the action of the guide slope, the film is automatically aligned and continues to be pushed in until its edge is firmly clamped by the clamping strip 3112 of the clamping device 311. At the same time, the infrared sensor 3116 is blocked and sends a prompt that it is in place. The doctor can then observe the film image through the uniform and bright backlight. If it is necessary to adjust the brightness or switch to digital image mode, it can be done by using the switch button 341 below.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
