[0041] In this embodiment, the portable mechanism 400 is a structure for fixing the sharps collection bucket 1 on the treatment cart.

[0042] like Figure 1 As shown, the portable mechanism 400 includes a portable installation box 401 fixedly installed on the left side of the sharps collection bucket 1, the inner bottom wall of the portable installation box 401 is rotatably connected to a screw rod 402 that passes through the top of the portable installation box 401 through a bearing, the top of the screw rod 402 is fixedly connected to a handle 403, the outer side of the screw rod 402 is threadedly connected to a lifting block 404, and a movable hole 405 for the lifting block 404 to slide and fit is opened on the left side of the portable installation box 401, and the left side of the lifting block 404 and the left bottom of the portable installation box 401 are fixedly connected with an L-shaped clamp block 406, and the two L-shaped clamp blocks 406 are mirror-symmetrical in upper and lower directions, so as to fix the sharps collection bucket 1 on the treatment cart.

[0043] The working principle of the above embodiment is:

[0044] (1) When in use, the medical staff first passes the pillow through the shear hole 311 and inserts the needle into the needle storage chamber 201, so that the infusion tube above the needle is located between the opposite sides of the two blades 308, keeping the needle in a vertical state. Then, the medical staff alone or two people use two fingers to push the two pull handles 3101 in opposite directions, and under the limiting effect of the fixed block 306, the push rod 3071 is driven to move toward the shear hole 311 and continuously squeeze the spring 3072. Then, the push rod 3071 pushes the blade 308 toward the shear hole 311 until the two blades 308 are in contact, thereby cutting the infusion tube. After the infusion tube is cut, its needle falls into the needle storage chamber 201, and the two fingers are released. The blade 308 is elastically stored under the rebound effect of the spring 3072. The handle 302 is reset to the original position, and then the handle 302 is held and pushed. The sliding connection between the limit moving block 3031 and the annular limit groove 3032 drives the circular recessed block 301 to rotate stably in place. When the medical staff aligns the handle 302 with the infusion tube storage chamber 202 by observing the mark on the label 304, the infusion tube is discarded into the infusion tube storage chamber 202 through the discard port 312. The above operation can be repeated to drop the syringe into the syringe storage chamber 203. When the sharps collection barrel 1 needs to be sealed, hold the auxiliary handle 3145 and pull it. The sealing plate 3144 is driven to move stably left and right under the sliding connection between the sliding block 3143 and the adjusting groove 3142. When the sealing plate 3144 completely covers the discard port 312, the sharps collection barrel 1 can be sealed.

[0045] (2) When the sharps collection bucket 1 needs to be placed on the treatment cart, first place the two L-shaped clamps 406 on the outside of the treatment cart pole, then hold the handle 403 and turn it, and drive the screw rod 402 to rotate stably in place under the rotation support of the bearing. Since the lifting block 404 can only move up and down in the movable hole 405 and the portable installation box 401, the lifting block 404 moves stably up and down on the outside of the screw rod 402 under the thrust of the inner thread rotation, thereby driving the top L-shaped clamp 406 to move up and down. When the two L-shaped clamps 406 are in contact with each other, the sharps collection bucket 1 can be fixed on the treatment cart.

[0046] Compared with the prior art: the infusion needle sharps bucket with its own cutting device can provide a function of conveniently separating and cutting the infusion tube and the needle through the mutual cooperation between the storage chamber assembly 200 and the cutting mechanism 300 on the sharps collecting bucket 1, thereby avoiding the medical staff from preparing scissors extra. At the same time, the blade of the scissors can be shielded to avoid scratches, and two people can also cut at the same time, thereby improving the safety and convenience of the cutting operation. In addition, the sharps collecting bucket can be sealed after being filled, and the surface of the cutting device can be prevented from being contaminated by blood, tissue fluid, bacteria and other adhesions. The sharps collecting bucket 1 can be fixed on the treatment cart through the mutual cooperation between the storage chamber assembly 200 and the portable mechanism 400 on the sharps collecting bucket 1. At the same time, it is also convenient for medical staff to take the sharps collecting bucket 1 from the treatment cart, which is convenient for medical staff to use, thereby effectively improving the use effect of the existing infusion needle sharps bucket and solving the problem of poor use effect of the existing infusion needle sharps bucket.
