Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical imaging optical film adaptive reading device. Background Art

[0002] Medical imaging refers to the technology and process of obtaining images of internal tissues of the human body or a part of the human body in a non-invasive manner for medical treatment or medical research. One of the most commonly used medical imaging equipment is the X-ray device, which generates black and white images of bones and tissues by emitting X-rays to the human body and receiving the reflected X-rays through a sensor. The generated light film is placed on a film viewing light for the doctor to examine.

[0003] A film viewing light usually consists of a frame and a lighting device. The lighting device mainly consists of a light source and some optical components. The light source is usually an LED, fluorescent lamp or spotlight. These light sources can provide high-brightness white light to meet the color temperature and color reproduction requirements required for viewing medical images. Then, through optical components such as specially designed reflectors and diffractors, the light is evenly distributed and accurately projected to avoid problems such as shadows and light spots that affect the viewing effect.

[0004] During the use of the film viewing lamp, medical staff hold the light sheet and slide it into the gap between the bracket and the lighting device, thereby fixing the light sheet to the film viewing lamp. However, the light sheet and the film viewing lamp are fixed by an elastic fixing connection, which may cause the light sheet to bend or wrinkle during the light sheet fixing process, causing damage to the viewing film and affecting the medical staff's reading effect.

[0005] To this end, the prior art has proposed a medical image reading device, which uses a dustproof cleaning mechanism to prevent dust from adhering to the glass, realizes multi-film comparison through a comparison mechanism to improve the accuracy of reading, and amplifies the details on the image through an amplification mechanism to improve the accuracy of disease examination, but the problem has not yet been solved.

The deflection plate 372 is re-extended under the action of the telescopic spring 373 and extends into the connecting cavity 392, so that the shaft sleeve 37 and the driving block 39 form a whole and move synchronously. When the fixed rack 34 drives the engaging plate 2 to complete the fixation of the optical sheet, the shaft sleeve 37 just completely enters the driving block 39. The driving block 39 moves vertically downward under the action of the shaft sleeve 37. The shaft sleeve 37 no longer supports the push plate. The push plate slides vertically downward for a distance under the action of gravity and the fixed rack 34 and then remains fixed. At this time, the compression spring 35 is still in a compressed state and continues to cooperate with the driving wheel 33 to drive the fixed rack 34 to slide. The fixed rack 34 and the driving wheel 33 are de-toothed and no longer rotate. The drive block 39 is provided with an inclined surface 393 at one end close to the shaft sleeve 37.
