Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and specifically refers to a CT film reading device for neurology. Background Art

[0002] CT examination is a commonly used medical imaging examination method in neurology. It uses X-rays to perform tomographic scans on the human head to obtain clear images of the brain structure. Doctors can understand the structure, function and pathological conditions of the patient's brain by observing and analyzing the CT films obtained by the CT examination device, which helps doctors to make accurate diagnoses of brain diseases.

[0003] When doctors are reading films, they usually hold the CT film in their hands and read the CT images under the illumination of a background light source. This reading method is relatively simple, but there are problems such as unstable images, unclear reading, and inaccurate observation, and it cannot meet the needs of simultaneous reading of multiple CT films. The existing CT reading device is mainly a medical viewing light box, which fixes the CT film on the medical viewing light box and uses the background light emitted by the medical viewing light box to achieve clear display of the CT film. However, this medical viewing light box has a fixed shape and size, and its direction cannot be flexibly adjusted.

[0030] Working principle and workflow: The device is provided with a film reading component 7. The doctor can drive the second worm 22 to rotate by turning the second knob 37, and the second worm 22 drives the second worm wheel 23 to rotate, so that the scissor rod 20 rotates. The film reading component 7 drives the two symmetrical film reading brackets 8 to move closer to or away from each other through the scissor rod 20, thereby changing the distance between the fixing components 24, and achieving the effect of clamping and fixing CT films 40 of various sizes.

[0032] In order to obtain the best reading angle, the doctor can turn the rotating cylinder 3, which can drive the multiple reading components 7 to rotate when the rotating cylinder 3 rotates, and adjust the reading components 7 to a position suitable for reading. At the same time, by turning the first knob 16, the first worm 15 is rotated and drives the first worm gear 17 to rotate to realize the rotation of the reading component 7, thereby adjusting the vertical angle of the reading component 7. The support shaft 14 can also be moved to make the adjustment block 13 slide in the adjustment slot 12, so that the reading component 7 can be rotated relative to the main lifting block 11, and the horizontal angle of the reading component 7 can be further adjusted.

The lighting lamp 35 is arranged on the back of the CT film 40 to provide light for the CT film 40 so that the image on the CT film 40 can be displayed more clearly. The lamp holder 34 is connected to the scissor rod 20 through the lamp rotating rod 32 and the lamp sliding rod 33. During the retraction and extension of the scissor rod 20, the lamp rotating rod 32 rotates relative to the lamp holder 34, and the lamp sliding rod 33 slides in the lamp sliding rail 36, so as to ensure that the lighting lamp 35 is always parallel to the film reading bracket 8. The distance between the lighting lamps 35 is reduced or increased as the scissor rod 20 is retracted and extended, so as to adapt to the lighting requirements of CT films 40 of different sizes and ensure the balance of the light receiving range of the CT film 40. The control button 39 and the lighting tube 35 are electrically connected to a control circuit board disposed in the base 1 through wires, respectively.
