Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to an auxiliary device for vascular CT imaging and a use method thereof. Background Art

[0002] CT stands for computer tomography. It uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with extremely sensitive detectors to perform cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images. It can be used to check a variety of diseases. When scanning cardiovascular and cerebrovascular patients, CT requires multi-layer scans of the patient's brain and heart. Existing CT mainly uses film to facilitate doctors' observation and patients' convenience in carrying CT data when transferring to other hospitals. Doctors need to place the film on the surface of the viewing light box and use the LED backlight panel on the back of the viewing light box to view the specific position on the film. Since cerebrovascular and cardiovascular CT films have a large number of scan layers, the radiology department needs to issue images of each scan layer, so multiple CT films are required; when multiple films need to be placed side by side on a longer light box for display, doctors need to arrange them horizontally on the light box one by one, and fix the films one by one through magnetic suction parts, which makes the placement of films more troublesome, time-consuming, and inconvenient for doctors to operate; there is a lack of a device that can automatically place multiple CT films side by side and in order on the light-emitting surface of the light box, and automatically fix the top of each CT film to the light box while placing them, without the need for manual operation by doctors, thereby greatly improving the efficiency of doctors viewing CT films.

[0010] Preferably, the method for using the auxiliary device for vascular CT imaging comprises the following steps: S1: When the device is in use, firstly, the top of the film loading box is opened by the opening and closing component, and the corresponding number of films are placed in the film loading box in the order of viewing according to the number and order of the films to be viewed, and the opening and closing component is released while limiting the positions of the films in the film loading box, and then the feeding component is controlled by the driving switching device to feed the first film to one end of the upper part of the light-emitting area of ​​the light-emitting light box; S2: When the film is about to leave the film loading box, the driving switching component controls the magnetic attraction component and the linkage component to work synchronously, and when the film completely leaves the film loading box, two magnetic attraction components are synchronously launched to the two ends of the top of the film, so that the top of the film and the magnetic attraction layer of the light box are fixed by magnetic attraction; S3: After the first film is placed and fixed, the linkage component is controlled to rise and reset by driving the switching device. While resetting, the loading component will not load the next film, but will be linked with the horizontal moving device to make the film loading box move along the slide rail to one side of the first film. When the linkage component rises and resets to the initial position, the film loading box also stops moving. At this time, the film loading box is offset from the position of the first film. Then repeat the above steps to complete the placement and fixation of the second film, and so on, thereby realizing the automatic placement and fixation of multiple CT films.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when it is necessary to place and fix several CT films on the luminous surface of the luminous light box in sequence, the closing plate is first pushed in the direction away from the luminous light box to expose the through opening at the top of the film loading box, the second spring contracts, and the limit plate is driven to slide together to expose the loading chamber under the push of the toggle block at the bottom of the closing plate, the first spring contracts, and then the corresponding number of films are vertically placed into the loading chamber according to the viewing order according to the number and order of the films to be viewed, the bottom of the first film to be placed is between the first loading roller and the second loading roller and cannot fall, and then the closing plate is loosened to reset it to close the through opening at the top of the film loading box, so that the limit plate is synchronously reset and stops against the side end of the adjacent film, thereby limiting the position of several films, and then the driving motor is controlled to work, and its output end rotates clockwise, driving the first pulley and the first transmission belt to drive The first gear rotates, thereby driving the switching gear to slide to one side of the arc slide and mesh with the second gear, and then the first feeding roller is driven to rotate under the action of the second pulley and the second transmission belt, thereby driving the first feeding roller and the second feeding roller to rotate synchronously and in opposite directions, thereby conveying the first film downward and gradually passing through the discharge port. As the first film completely leaves the film feeding box and is fixed on the luminous surface of the luminous light box through subsequent equipment, due to a gap on the side of the feeding chamber close to the discharge port, the limit plate is driven to slide toward the discharge port under the action of the limit plate and the first spring, and with the cooperation of the inclined surface at the bottom of the feeding chamber, the subsequent film is driven to slide toward the discharge port, so that the first feeding roller and the second feeding roller are in contact with the bottom of the second film, thereby realizing the automatic feeding of the CT film toward the luminous light box without manual operation.

[0012] In the present invention, when the first feeding roller and the second feeding roller rotate to convey the film, the rotation of the first gear drives the third gear to rotate counterclockwise, thereby driving the first tooth plate to descend, and when the film is about to leave the film feeding box, the bottom of the trigger block contacts the top of the matching block, thereby driving the second pushing rod to slide in the direction close to the light-emitting light box, thereby pushing the magnetic suction component at the bottom to the direction close to the light-emitting light box and leaving the feeding rack, and when the film completely leaves the film feeding box, the magnetic suction component leaves the feeding rack, and under the action of the connecting rod, the magnetic suction components in the two magnetic suction components synchronously leave the feeding rack and are magnetically attracted to the upper part of the light-emitting light box, and the upper part of the film is fixed to the light-emitting surface of the light-emitting light box through the magnetic suction component, thereby realizing the effect of automatically fixing the CT film on the light-emitting light box.

[0013] In the present invention, when the film is loaded to the luminous surface of the luminous light box and fixed by the magnetic attraction part, the driving motor is controlled to work to drive its output end to rotate counterclockwise, thereby driving the switching gear to disengage the second gear and mesh with the first bevel gear, thereby driving the second bevel gear to rotate. As the second bevel gear rotates, the third gear first rotates clockwise to drive the trigger block to rise and disengage from the matching block, thereby driving the second pushing rod to reset, and then continuing to drop a magnetic attraction part inside the loading rack to facilitate subsequent fixing work, and as the trigger block rises, the second bevel gear rotates, and the fourth gear is driven to rotate under the cooperation of the third pulley and the third transmission belt, thereby controlling the film loading box to slide horizontally along the slide rail. When the trigger block is reset, the film loading box also stops moving. At this time, the film loading box is staggered with the position of the first film, and then the above steps are repeated to complete the placement and fixation of the second film, and so on, thereby realizing the automatic placement and fixation of multiple CT films.
