Since infusion needles are sharp, if not properly collected and treated, they are likely to stab others, and even spread viruses, bacteria, etc., leading to medical accidents. For the needles discarded after infusion, special sharp containers are generally used as collection containers to put the needles into the sharp containers for unified collection. However, for infusion set needles, scissors must be used additionally to cut them off and then throw them into the sharp container. In this way, not only additional tools such as scissors are needed, but the operation is rather troublesome. Sometimes, cutting the needles with scissors will cause the needles to fly around and fall outside the sharp container, making it difficult to find.
[0003] There is a patent with the application number CN201510247031.1, which discloses a sharp container, including a box body, a box cover and a rotating cover. The box body is hermetically connected with the box cover, and the rotating cover is installed on the box cover. The box cover is provided with holes for small syringe needles and holes for longer hose infusion set needles. The rotating cover is provided with sharp object collection holes. A pair of scissors is arranged under the box cover, the position of the scissor blade is corresponding to the position of the hole for the longer hose infusion set needle, the scissor handle extends outside the box cover, the scissor shaft is located on the box cover, and a notch is opened on the box cover at the position corresponding to the scissor handle. This patent can use the scissors arranged in the sharp container to cut off the needles on the infusion set and drop them into the box body. However, since the scissor structure is exposed, there is a risk of accidentally injuring the user. Content of the Utility Model

[0031] Example 2
[0032] The difference between this embodiment and embodiment 1 is that Figure 6 As shown, this embodiment adjusts the position of the needle withdrawal hole 34 and provides a needle withdrawal hole shielding plate 45 on the rotating plate 4; through the needle withdrawal hole shielding plate 45, when the rotating plate 4 and the fixed plate 3 cooperate to close the top of the sharps box, the needle withdrawal hole 34 can be closed at the same time, so that the inside and outside of the sharps box are completely sealed to prevent the needle from leaking; and when the rotating plate 4 rotates to open the sharps box, the needle withdrawal hole shielding plate 45 no longer closes the needle withdrawal hole 34, and the needle can be removed through the needle withdrawal hole 34.
[0033] Example 3
[0034] The difference between this embodiment and embodiment 2 is that Figure 7As shown, in this embodiment, lever rods 5 are provided on both sides of the opening of the fixing plate 3. At the same time, the installation direction of the torsion spring 6 in this embodiment is opposite to that in Embodiment 1, so that the initial position of the rotating plate 4 is as Figure 6 shown in the figure, which is the position that completely closes the opening of the fixing plate 3. At the same time, the needle-pulling hole 34 in this embodiment is inclined, and a rotating plate extension 44 is provided on the rotating plate 4, as Figure 8 shown. The rotating plate extension 44 cooperates with the needle-pulling hole 34 to close the needle-pulling hole 34 at the initial position of the rotating plate 4.
[0035] In this embodiment, during use, first, by pinching the lever rod 5 on the left side of the fixing plate 3 and the lever rod 5 on the rotating plate 4, the rotating plate 4 is rotated clockwise to open the opening of the fixing plate 3. At this time, the infusion set to be cut can be placed at the card slot 31. After the infusion set is placed in place, release the lever rod 5. Under the action of the torsion spring 6, the rotating plate 4 will return to its original position, that is, the torsion spring 6 drives the rotating plate 4 to cut the infusion set. If the force of the torsion spring 6 is not enough to cut off the infusion set, then, as in Embodiment 1, pinch the lever rod 5 on the right side of the fixing plate 3 and the lever rod 5 on the rotating plate 4 to apply force to cut off the infusion set. In this embodiment, when the sharp instrument box is not in use, the opening of the sharp instrument box will remain closed, which can prevent the needles stored inside from leaking when the sharp instrument box accidentally topples over. At the same time, the torsion of the torsion spring 6 can be used to cut the infusion set, which can effectively save the labor of medical staff when a large number of infusion set needles need to be processed, achieving high efficiency and labor saving.
[0036] When it is necessary to use the needle-pulling hole 44 to remove the needle, the above operation can also be performed, that is, pinch the lever rod 5 to rotate the rotating plate 4 clockwise to open the needle-pulling hole 34. When released, under the action of the torsion spring 6, the rotating plate 4 returns to its initial position, so that the needle-pulling hole 44 is closed by the rotating plate extension 44, thereby closing the internal and external spaces of the sharp instrument box and preventing leakage.
