Please refer to Fig. 5-8, on the basis of the first embodiment, the surface of the lid 1 is provided with a second insertion port 5 that penetrates the surface of the lid 1, and the setting of the second insertion port 5 is used to insert the infusion tube The needle, the lower surface of the lid 1 is fixedly connected with a fixed block 16, the surface of the fixed block 16 is provided with a treatment groove 15 that runs through the surface of the fixed block 16, and the treatment groove 15 is located directly below the second insertion port 5, so that the infusion tube needle After dropping into the second delivery port 5, it can smoothly enter the treatment tank 15 to prepare for the cutting of the infusion tube needle. The surface of the fixed block 16 is provided with a movable groove 17 running through the surface of the fixed block 16. The pressing groove 6 on the surface of the box cover 1 is penetrated, and a cutting mechanism is arranged inside the pressing groove 6 .

The cutting mechanism comprises a pressing sleeve 7, the surface of the pressing sleeve 7 is slidingly connected with the surface of the pressing groove 6, the inner wall of the pressing sleeve 7 is slidingly connected with a rotating rod 13, and the left and right sides of the pressing sleeve 7 are fixedly connected with a limiting rod 24, two The shape of the limiting rod 24 is a lollipop, and the left and right sides of the inner wall of the pressing groove 6 are provided with first limiting grooves 19 in a "convex" shape. The surface is slidingly connected, and then through the setting of the first limiting groove 19 and the limiting rod 24, the movement track of the pressing sleeve 7 is limited, so that the pressing sleeve 7 can only slide up and down inside the pressing groove 6, so that the pressing sleeve 7 does not Rotation will occur inside the pressing groove 6, thereby ensuring that the pressing sleeve 7 will not rotate following the rotation of the rotating rod 13, thereby ensuring the reasonable operation of the device. The surface of the rotating rod 13 is fixedly connected with a limiting plate 22, and the limiting plate 22 is rotationally connected with the surface of the pressing groove 6, the inner wall of the pressing groove 6 is provided with a second limiting groove 23, the surface of the limiting plate 22 is slidingly connected with the inner wall of the second limiting groove 23, and then the limiting plate 22 and the second limiting The setting of the groove 23 makes the rotating rod 13 frame in the inside of the pressing groove 6, supports the rotating rod 13, and restricts the movement track of the rotating rod 13 at the same time, so that the rotating rod 13 will not move in the pressing groove 6. Move up and down, and then ensure the smooth operation of the device, the surface of the rotating rod 13 is provided with a spiral groove 21, the inner wall of the spiral groove 21 is slidably connected with a connecting rod 20, and the right end of the connecting rod 20 is fixedly connected to the inner wall of the pressing sleeve 7, and the rotating rod The surface of 13 is movably socketed with the torsion spring 14 fixedly connected to the surface of the rotating rod 13, and the end of the torsion spring 14 away from the rotating rod 13 is fixedly connected to the bottom of the lid 1, and the lower end of the rotating rod 13 is fixedly connected with a blade 18, the blade The surface of 18 is slidably connected with the inner wall of movable groove 17, and then through the setting of movable groove 17, enough movement space is provided for the circular motion of blade 18, and then avoided the situation that fixed block 16 affects blade 18 movement, guaranteed the stability of device run smoothly.

When removing the needle on the infusion tube, press the pressing sleeve 7, and then make the inner wall of the pressing sleeve 7 slide down on the surface of the rotating rod 13, and then make the connecting rod 20 squeeze the inner wall of the spiral groove 21, and then Make the rotating rod 13 rotate, and then drive the blade 18 to rotate, and drive the torsion spring 14 to deform at the same time, insert the needle of the infusion tube in the second delivery port 5 at this time, and make the needle of the infusion tube break away from the treatment tank 15 completely, and then At this time, the infusion tube blocks the movable groove 17, and then no longer presses the pressing sleeve 7, and then under the elastic force of the torsion spring 14, the rotating rod 13 is driven to reverse, and then the blade 18 is driven to reverse, because the infusion tube is opposite to the blade 18. Then, with the rotation of the blade 18, the blade 18 collides with the infusion tube, and then the infusion tube is bent. At this time, the operator pulls the upper end of the infusion tube, and the needle of the infusion tube is completely separated from the treatment. Groove 15, and the shape of the needle of the infusion tube is flat, and the texture is relatively hard. At the same time, the pulling force of the infusion tube on the needle is an oblique tension, which will cause the upper end of the needle to be stuck in the processing groove 15, and then make the infusion tube in a relatively tight position. stretched state, and then the blade 18 can cut off the infusion tube, so that the needle of the infusion tube falls to the recovery box 2, and then through the setting of the cutting mechanism, the medical staff can complete the cutting and collection of the needle of the infusion tube at one time, so that the medical staff It is no longer necessary to cut the needle of the infusion tube first and then collect it, thereby improving the efficiency of the medical staff in handling the infusion tube, and avoiding the problem of the liquid in the infusion tube splashing on the medical staff, and making the medical staff no longer need to hold the needle , thereby reducing the possibility of the medical staff being stuck by the needle, protecting the medical staff, and improving the safety of the device during use.

Working principle: When removing the needle on the infusion tube, press the pressing sleeve 7, and then make the inner wall of the pressing sleeve 7 slide down on the surface of the rotating rod 13, and then make the connecting rod 20 squeeze the inner wall of the spiral groove 21 Press, and then make the rotating rod 13 rotate, and then drive the blade 18 to rotate, and at the same time drive the torsion spring 14 to deform. Under the elastic force of the torsion spring 14, the rotating rod 13 is driven to reverse, and then the blade 18 is driven to reverse. Since the infusion tube blocks the movement path of the blade 18, the blade 18 can cut off the infusion tube, so that the needle of the infusion tube falls to the Recycling box 2.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the gist of the present invention. kind of change.
