Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a capping device for spiral tubes. Background Technology

[0002] Urine analysis is a fundamental and crucial diagnostic tool in medical procedures. The collection, storage, and testing of urine samples have a decisive impact on ensuring the accuracy of diagnostic results. Urine spiral tubes, a commonly used urine sample container, are designed to prevent contamination or evaporation of samples during collection, transportation, and storage through a tight screw cap, thus ensuring sample integrity and stability. Currently, the opening of urine spiral tube caps is mostly done manually by medical personnel. There is no equipment or instruments available for manually capping patient specimens after testing, and manual opening of urine spiral tube caps has the following disadvantages: 1. It is labor-intensive; 2. It is time-consuming; 3. It poses significant biosafety risks, such as injury to the operator from a broken tube opening, and the sudden release of local negative pressure during opening causing blood splatter and aerosol generation, potentially leading to bacterial and viral infections of medical personnel. Furthermore, during manual opening, the operator's hands may directly contact the sample container or cap, introducing external contaminants. Utility Model Content

A slide table 13 is threaded onto the lead screw 10. A mounting plate 14 is fixedly connected to the front side of the slide table 13. A third motor 15 is mounted on the mounting plate 14. The output end of the third motor 15 is connected to a second transmission rod 16. A sleeve 17 is fixedly connected to the other end of the second transmission rod 16.

[0039] The inner wall of the sleeve 17 is provided with a protrusion 18 that contacts the cap of the spiral tube and increases friction. Multiple protrusions 18 are provided along the circumference of the inner wall of the sleeve 17.

[0040] A controller 19 is installed on the workbench 1, and the controller 19 is electrically connected to motor 2 (first motor), motor 9 (second motor), and motor 15 (third motor). Motors 2, 9, and 15 are stepper motors. Guide rods 12 are provided on both sides of the lead screw 10.

[0041] Working principle:

[0042] When using this device, first place the urine spiral tubes 20 to be tested into the placement slots 5 of the placement platform 4 in sequence, ensuring that each spiral tube is firmly clamped by the elastic rubber rings 6; start the first motor 2 through the controller 19, and drive the placement platform 4 to rotate through the first transmission rod 3.

[0043] Then, the controller 19 starts the second motor 9, which drives the slide 13 to move downward along the lead screw 10 via the threaded connection between the lead screw 10 and the slide 13. Simultaneously, the guide rod 12 provides additional stability. When the slide reaches the preset position, the sleeve 17 fits the cap of the urine spiral tube 20; then, the third motor 15 is started, driving the sleeve 17 to rotate via the second transmission rod 16. The protrusion 18 on the inner wall of the sleeve contacts the cap of the urine spiral tube and applies torque, thereby opening the cap.

[0044] Then the controller controls motor 9 to reverse, driving slide 13 to move upward along lead screw 10. Then motor 2 drives the placement platform 4 to rotate, causing the next urine spiral tube 20 to rotate to the vertical position below sleeve 17, so as to open the cap of the next urine spiral tube 20.
