Description

Technical Field

[0001] The utility model relates to the technical field of medical detection, in particular to a drug sensitivity test inoculation instrument. Background Art

[0002] The drug sensitivity test is the abbreviation of the antimicrobial sensitivity test, which refers to a type of test that determines the sensitivity or resistance level of bacteria to antimicrobial drugs in vitro. Currently, the commonly used drug sensitivity test methods include: paper strip method (KB method), dilution method (broth dilution method, agar dilution method), E-Test method, etc.

[0003] The existing drug sensitivity test inoculator completes the inoculation through a simple inoculator. During the inoculation process, a sterile cotton swab needs to be fixed on a stainless steel plate to form a simple inoculator. Then the user holds the inoculator and puts it on the bacterial plate, so that the sterile cotton swab picks up the bacterial solution in the bacterial plate. After the bacterial solution is picked up, the sterile cotton swab picks up the bacterial solution on the inoculation loop, which is convenient for inoculating the inoculation loop. During the inoculation process, the user holds the inoculator to perform the inoculation operation, so that the user's hand contacts the inoculator more frequently, causing some bacteria to contaminate the inoculator, and during the inoculation process, only one inoculation operation can be performed at a time, and the subsequent inoculation operation takes a lot of time, and causes the user to be more tired, which affects the accuracy of the test results.

The placing frame 22 is connected to a sponge pad 23 for protection when placing sterile cotton swabs and bacterial suspension containers. The first docking plate 5 and the first sliding plate 7 are both connected to the side facing each other. The first anti-slip pad 24 plays an anti-slip role when the sterile cotton swab is fixed.The second anti-slip pad 25 is connected to the second butt joint plate 12 and the second sliding plate 13 on the side facing each other.

[0024] When the device needs to be used, when vaccination is required in the drug sensitivity test, the user first places the inoculation rings to be tested on the corresponding placement rings 15, and then pulls the first sliding plate 7 to move backward along the first connecting rod 6. During the movement of the first sliding plate 7, the first sliding plate 7 drives the connecting block 8 thereon to move backward, so that the connecting block 8 thereon is out of contact with the third magnet 801. When the first sliding plate 7 moves to a suitable position, the sterile cotton swab is placed inside the first docking plate 5. At the same time, the sterile cotton swab contacts the first anti-slip pad 24 on its inner wall. After the sterile cotton swab is placed, the first sliding plate 7 is pulled again to drive the connecting block 8 thereon to move forward along the first connecting rod 6. When the first sliding plate 7 moves back to its original position, it is convenient to place the sterile cotton swab. The sterile cotton swab is fixed between the first docking plate 5 and the first sliding plate 7, and the first anti-slip pad 24 therein can prevent the sterile cotton swab from slipping. At this time, after the connecting block 8 on it moves back to its original position, the connecting block 8 on it contacts with the third magnet 801 again and is sucked by it. When the sterile cotton swab is fixed, the placement rack 22 under the first docking plate 5 is rotated ninety degrees clockwise along the rotating rack 21. When the placement rack 22 under the first docking plate 5 is rotated, the placement rack 22 is released, and then the second sliding plate 13 is pulled backward along the second connecting rod 11. The movement of the second sliding plate 13 drives the connecting block 8 on it to move backward. During the movement of the connecting block 8 on it, it is out of contact with the corresponding third magnet 801, and then the bacterial suspension container is placed The second sliding plate 13 is then pulled to drive the connecting block 8 thereon to move forward. When the second sliding plate 13 moves back to its original position, the bacterial suspension container can be fixed between the second docking plate 12 and the second sliding plate 13, and the second anti-skid pad 25 therein can play an anti-skid role for the bacterial suspension container, because the connecting block 8 thereon also returns to its original position, so that the connecting block 8 thereon contacts and is attracted by the corresponding third magnet 801, and then the placing rack 22 under the second docking plate 12 is rotated ninety degrees clockwise along the rotating rack 21. When the placing rack 22 under the second docking plate 12 is rotated completely, the placing rack 22 is released, and the lifting plate 3 is pulled along the guide The guide frame 2 moves downward, and the lifting plate 3 moves so that the second magnet 301 is out of contact with the first magnet 201. The lifting plate 3 moves and drives the guide rod 4, the first connecting plate, the first connecting rod 6, the first sliding plate 7, the connecting block 8 and the sterile cotton swab to move downward, and the rotating frame 21, the placement frame 22 and the connecting frame 1602 also move downward accordingly. During the movement of the sterile cotton swab, the sterile cotton swab contacts the bacterial suspension container and moves downward along the inside thereof. When the sterile cotton swab moves to a suitable position inside the bacterial suspension container, the sterile cotton swab is adhered to the bacterial suspension, and then the lifting plate 3 is pulled upward along the guide frame 2. The lifting plate 3 moves and drives the guide rod 4, the first connecting plate, the first connecting rod 6, the first sliding plate 7, the connecting block 8 and the sterile cotton swab to move upward.The rotating frame 21, the placement frame 22 and the connecting frame 1602 also move upward accordingly. When the lifting plate 3 moves back to the position at the top of the guide frame 2, the second magnet 301 contacts and attracts the first magnet 201, and then pushes the second docking plate 12 to move backward. The movement of the second docking plate 12 drives the connecting block 8, the corresponding third magnet 801, the second connecting rod 11, the adjacent connecting block 8, the second sliding plate 13 and the telescopic rod 10 thereon to move backward. The rotating frame 21 and the placement frame 22 under the second docking plate 12 also move backward accordingly. When the second docking plate 12 moves to a suitable position, the lifting plate 3 is pulled downward along the guide frame 2 again. The movement of the lifting plate 3 drives the guide rod 4, the first connecting plate, the first connecting rod 6, the first sliding plate 7, the connecting block 8 and the sterile cotton swab with bacterial suspension to move downward. The rotating frame 21, the placement frame 22 and the connecting frame 1602 also move downward accordingly. While the lifting plate 3 moves, the lifting plate 3 brings The movable connecting frame 1602 moves downward, and the movement of the connecting frame 1602 makes the pull rope 1601 no longer remain in a taut state. At this time, the torsion spring 17 is reset, and the winding disk 16 rotates to make the pull rope 1601 wind back inside it. During the rotation of the winding disk 16, the winding disk 16 drives the first gear 18 to rotate, and the first gear 18 rotates to contact the second gear 20 and drive it to rotate. The second gear 20 rotates to drive the connecting shaft 19, its corresponding placement ring 15 and the inoculation ring to rotate. When the lifting plate 3 moves to a suitable position, the lifting plate 3 contacts and is blocked by the block 501. When the lifting plate 3 is blocked, the sterile cotton swab with the bacterial suspension contacts the inoculation ring and smears the bacterial suspension on the inoculation ring. When the bacterial suspension is applied, the lifting plate 3 is pulled again to continue to move downward along the guide frame 2. During the movement of the lifting plate 3, the first docking plate 5 is blocked by the block 501 and remains stationary. At the same time, the inoculation ring rotates, which is convenient for inoculating the inoculation ring.
