Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an automatic sharps box. Background Art
[0002] A sharps box is a medical waste recycling box used to collect damaging waste, including discarded metal sharps, such as needles, scalpels, etc. and discarded glass sharps, such as glass ampoules, etc., as well as sharps of other materials. When medical staff use a sharps box to remove the needle from a syringe, they usually clamp the edge of the connection between the needle and the syringe on the teardrop-shaped through-hole on the sharps box, and then pull the syringe upward to separate the syringe from the needle, allowing the needle to fall directly into the sharps box. However, in actual operation, if the needle is not properly clamped, the needle will be brought out when the syringe is pulled out. If the staff is not careful, the needle will pierce the medical staff's hand. When using the teardrop-shaped through-hole on the sharps box to remove the needle on the infusion tube, the teardrop-shaped through-hole often cannot clamp the needle on the infusion tube.
[0003] For this purpose, we design an automatic sharps box here. Utility Model Content

The center of the fan-shaped circle of the first opening 11-2 coincides with the center of the circle of the cover body 11, and the fan-shaped angle of the first opening 11-2 is 180 degrees. Six L-shaped cross-section pressing plates 12 are installed at the top edge of the cover body 11, and the six pressing plates 12 are distributed in a circular array with the center of the circle of the cover body 11;
[0025] See also Figure 3 and Figure 4 The rotating member 13 is in the shape of a disc, and a connecting shaft 110 is installed at the bottom center of the rotating member 13. The connecting shaft 110 is rotatably installed in the mounting hole 11-1. The pressing plate 12 is pressed on the edge of the rotating member 13. The rotating member 13 is provided with a second opening 13-1 and a third opening 13-2. The second opening 13-1 and the third opening 13-2 are both located above the first opening 11-2. A ring 19 is installed on the top of the rotating member 13. The second opening 13-1 and the third opening 13-2 are both located inside the ring 19. The outer side of the ring 19 is evenly provided with anti-slip grooves. The rotating member 13 on the cover body 11 can be rotated by rotating the ring 19;
[0026] See also Figure 3The second opening 13-1 is fan-shaped, the center of the fan-shaped circle of the second opening 13-1 coincides with the center of the circle of the rotating member 13, the fan-shaped angle of the second opening 13-1 is about 60-90 degrees, and a blade 14 is installed on one side of the straight edge of the second opening 13, see Figure 6 When the rotating member 13 is controlled to rotate on the cover body 11, the first opening 11-2 and the second opening 13-1 can be staggered with each other, and then the blade 14 cooperates with the edge of the first opening 11-2 to play a shearing role, thereby shearing the infusion tube. Please refer to Figure 3-Figure 5 The third opening 13-2 is approximately in the shape of a water drop. The third opening 13-2 is located next to the edge of the second opening 13-1 where the blade 14 is located. A pressing piece 15 and a movable plate 16 are respectively provided at the top and bottom of the third opening 13-2.
