Description

Technical Field

[0001] The utility model relates to the field of drug sensitivity detection, in particular to a photo-taking light-filling adjustment device for drug sensitivity detection. Background Art

[0002] Drug sensitivity testing, also known as drug sensitivity or resistance testing, is a crucial testing technology in the medical field; its main purpose is to understand the sensitivity of a certain pathogenic microorganism to various antibiotics, thereby providing a scientific basis for the rational use of antibiotics in clinical practice.

[0003] The commonly used method for drug sensitivity testing is the paper diffusion method, which involves sticking a paper containing a quantitative antibiotic on an observation plate inoculated with the pathogen to be tested. After the observation plate is placed into a sealed box, the drug sensitivity paper on the surface of the observation plate is observed using a camera.

[0004] In existing drug sensitivity testing, lamps are usually fixed inside the box for supplementary lighting. During use and observation, it was found that when the distance between the lamp and the observation board is large, the brightness of the observation board surface will be weak, which will reduce the visibility of the drug sensitivity paper on the surface of the observation board, and thus affect the observation results.

[0005] Therefore, in order to solve the above problems, a device for adjusting the light filling during drug sensitivity detection and photography is proposed. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the present invention describes a device for adjusting the light supply for drug sensitivity detection and photography, comprising a box body; a pull plate is slidably connected to the middle of the box body; a circular plate is rotatably connected to the top of the box body; a screw is fixed to the bottom of the circular plate; the screw and the box body are arranged through and are rotatably connected; a slide is threadedly connected to the middle of the screw; a pair of lamps are installed at the bottom of the slide; a camera is installed at the top of the inner wall of the box body; rotating the screw causes the lamps and the slide to move relative to the pull plate, thereby enabling the device to adjust the distance between the lamps and the observation plate, so that the device can provide appropriate light supply to the surface of the observation plate, thereby improving the visibility of the drug-sensitive paper on the surface of the observation plate and improving the accuracy of the observation results.

[0008] Preferably, a plurality of grooves are provided in the middle of the circular plate; a vertical plate is fixedly connected to the top of the box body; a sliding rod is provided through the middle of the vertical plate and is slidably connected; a spring is fixed to the end of the sliding rod; the spring and the vertical plate are in a fixed relationship; the other end of the sliding rod is fixed to a fixed block; the fixed block and the groove are correspondingly arranged and are slidably matched; after loosening the sliding rod, the circular plate will be subjected to the friction of the fixed block and the groove, thereby realizing rapid fixation of the circular plate by the device, reducing the shaking of the circular plate due to collision when the device takes pictures and samples the observation plate, and improving the stability of the lamp when filling light on the observation plate.

[0009] Preferably, a plurality of elastic sheets are fixed to the middle part of the sliding rod; the elastic sheet is an arc-shaped structure; the elastic sheet is located between the vertical plate and the fixed block; by providing the elastic sheet, the shape of the elastic sheet will be restored after passing through the vertical plate and rub against the vertical plate, thereby reducing the pulling force required on the sliding rod when the staff adjusts the circular plate, and improving the convenience of fixing the sliding rod with the device.

[0010] Preferably, a buffer pad is fixedly connected to the middle part of the sliding rod; the buffer pad and the elastic sheet are both fixedly connected; when the elastic sheet passes through the vertical plate, the buffer pad will also pass through the vertical plate. When the staff releases the sliding rod, the elastic sheet will come into contact with the vertical plate, and the buffer pad will also come into contact with the vertical plate. Because the buffer pad is a flexible material, the buffer pad will absorb the impact generated when the elastic sheet and the vertical plate collide, reducing damage or scratches caused by the collision between the elastic sheet and the vertical plate.

[0011] Preferably, a first magnet is fixedly connected to the middle of the fixed block; a second magnet is fixedly connected to the inner wall of the groove; the first magnet and the second magnet are arranged correspondingly; when the fixed block enters the interior of the groove, the first magnet will move with the fixed block, and the distance between the first magnet and the second magnet will also change. The first magnet will be affected by the suction force of the second magnet, so that the fixed block will be affected by the magnetic force of the first magnet and the second magnet and quickly enter the interior of the groove, thereby improving the stability of the connection between the fixed block and the groove.

[0012] Preferably, a baffle is symmetrically fixed to the bottom of the slide; the baffle is an arc-shaped structure; when the lamp fills the observation plate on the surface of the pull plate, the baffle will block the light emitted by the lamp to other areas, reduce the scattering of light in the box, and reduce the interference of scattered light on the lighting conditions on the surface of the pull plate.

[0013] Preferably, a plurality of fins are fixed to the middle of the baffle; the fins are arranged at an angle; when the lamp works for too long, high temperature will be generated on the surface, and the heat will be transferred to the fins through the baffle. When the air flows in the box, it will come into contact with the fins. The fins will increase the heat dissipation area of ​​the lamp by the airflow, thereby realizing cooling of the lamp by the device.

[0014] The utility model is beneficial in that:

[0015] 1. The utility model describes a device for adjusting the light fill for drug sensitivity testing and photography. Rotating the screw causes the lamp, together with the slide and the pull plate, to move relative to each other, thereby enabling the device to adjust the distance between the lamp and the observation plate. This allows the device to provide appropriate light fill for the surface of the observation plate, thereby improving the visibility of the drug sensitivity paper on the surface of the observation plate and the accuracy of the observation results.

[0016] 2. In the device for adjusting the light supply for drug sensitivity testing and taking photos described in the present invention, after the slide rod is released, the circular plate will be subjected to the friction of the fixed block and the groove, thereby realizing the rapid fixation of the circular plate by the device, reducing the shaking of the circular plate caused by collision when the device takes photos and samples the observation plate, and improving the stability of the lamp when supplying light to the observation plate.
