Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a sharps box that prevents stab injuries. Background Art

[0002] A sharps box is a medical storage box used to collect sharps such as syringes, small glassware, blades, suture needles, etc. In the existing sharps box, when medical staff jam the syringe needle in the needle handle position of the sharps box, they need to drag the syringe to pull out the needle. During this process, the needle removal position of the sharps box will be deformed, and then the needle will be given downward kinetic energy at the moment of detachment. If there is a certain height of medical waste inside the sharps box, and the needle encounters harder waste during its falling process, the needle may rebound. If the needle pops out of the sharps box, it will cause injury to the medical staff, and the rebound may also throw the remaining medicine to the outside of the sharps box, thereby causing contamination, which is very dangerous. In addition, when placing an infusion needle in the sharps box, if the infusion tube with the needle is not completely placed in the sharps box, the needle will be exposed on the outside of the sharps box, and the medical staff will need to put the needle into it, and the hand may be pricked in the process.

The annular ring of the rotating frame 22 rotates in the concave groove of the upper cover 11 to drive the shielding plate to close the notch 14, the slide groove 15 and the pin insertion hole 16. At the same time, the first locking tooth at the bottom of the annular ring cooperates with the second locking tooth of the concave groove to prevent the rotating frame 22 from opening again. In addition, when the infusion needle is inserted, if the needle does not completely enter the barrel 12 and a part of it protrudes from the notch 14, the rotating seat 21 is rotated to drive the lever 23 to rotate in the barrel 12, and then the infusion needle is rolled into the barrel 12.

[0033] In this embodiment: the needle removal mechanism 3 includes two needle removal racks 31, and the two needle removal racks 31 are respectively slidably connected to the inner sides of the two slide grooves 15. A connecting seat 32 is fixed on the top of the two needle removal racks 31, and the connecting seat 32 is rotatably connected to the flip plate 33. A tough plate 34 is fixed to the lower side of the end of the needle removal rack 31 close to the syringe 4, and a needle removal seat 35 is fixed to the lower end of the tough plate 34. The front and rear sides of the needle removal rack 31 are provided with recesses that match the slide groove 15. The flip plate 33 is flipped to make it flip around the connecting seat 32 to a vertical state, and then the syringe 4 that needs to be removed is inserted into the needle insertion hole 16, and then the flip plates 33 on both sides are squeezed to drive the connecting seat 35. The seat 32 and the needle removal rack 31 move along the slide groove 15 toward the syringe 4. In the process of the needle removal racks 31 approaching each other, the needle removal seat 35 is pushed by the flexible plate 34 to fit the matching position of the needle and the syringe 4. At the same time, as the two needle removal racks 31 continue to approach each other, the flexible plate 34 at the lower end of the needle removal rack 31 will push the needle removal seats 35 on both sides of the needle diagonally downward, and then the two needle removal seats 35 press the needle tightly and move downward to pull it off the syringe 4, and then release the flap 33 and let the connecting seat 32 drive the needle removal rack 31 to reset, and then the flexible plate 34 drives the needle removal seat 35 to disengage the clamping of the needle, and the needle falls into the cylinder 12.

[0034] Working principle: When in use, the upper cover 11 is buckled on the upper end of the cylinder 12, and the hook ring at the lower end of the upper cover 11 cooperates with the locking ring at the upper end of the cylinder 12 to complete the locking of the upper cover 11 and the cylinder 12. At the same time, the sealing plate 13 is used to seal the upper end of the cylinder 12, and then the flap 33 on the connecting seat 32 is turned over to make it in a vertical upward state, such as Figure 3 and Figure 5 As shown;

[0035] When the needle of the syringe 4 needs to be removed, the syringe 4 that needs to be removed is inserted into the needle insertion hole 16, and then the flaps 33 on both sides are squeezed to drive the connecting seat 32 and the needle removal frame 31 to move along the slide groove 15 toward the syringe 4. In the process of the needle removal frames 31 approaching each other, the needle removal seat 35 is pushed by the flexible plate 34 to fit the needle and syringe 4 in the matching position, and then as the two needle removal frames 31 continue to approach each other, the flexible plate 34 at the lower end of the needle removal frame 31 will arch and push the two needle removal seats 35 to clamp the needle while driving the needle to move downward, and then the two needle removal seats 35 will pull the needle out of the syringe 4, and then release the flap 33 and let the connecting seat 32 drive the needle removal frame 31 to reset, and then the flexible plate 34 drives the needle removal seat 35 to disengage the clamping of the needle, and the needle falls into the cylinder 12 at this time, and then the syringe 4 with the needle removed can be taken out of the needle insertion hole 16, and in this process, the needle will not generate kinetic energy and cause collision;

[0036] At the same time, when the needle for infusion is inserted into the slot 14, if the needle does not enter the barrel 12 and protrude from the slot 14, the rotating seat 21 is rotated to drive the lever 23 to rotate inside the barrel 12, and then the infusion tube with the needle is wound by the rotation of the lever 23, so that the infusion needle protruding from the slot 14 is brought back into the barrel 12;

[0037] When the medical waste is required to reach the three-quarter position of the cylinder 12, the vertical flap 33 is turned over to make it in a horizontal state, such as Figure 7 As shown, the rotating frame 22 is then rotated with the rotating seat 21 as the rotation center, so that the shielding plate of the rotating frame 22 shields the notch 14, the slide groove 15 and the pin hole 16. At this time, the second locking tooth of the annular ring will cooperate with the first locking tooth of the concave groove, so as to completely lock the position of the notch 14, the slide groove 15 and the pin hole 16 on the top of the sealing plate 13 through the rotating frame 22.
