Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 This utility model provides a medical sharps container to prevent puncture wounds, including a sharps container body 1, with a lid 2 on the sharps container body 1; the sharps container body 1 is threadedly connected to the lid 2, the lid 2 has a circular opening, and a rotatable cylindrical body 3 is fitted inside the circular opening; the top edge of the cylindrical body 3 has a stop 4 that blocks the circular opening; a vertically sliding circular plate 5 is fitted inside the cylindrical body 3, the circular plate 5 has a throwing port 6 and a needle removal hole 7, and a pull rod 8 is located at the top center of the circular plate 5; a positioning mechanism is provided inside the cylindrical body 3 to prevent the circular plate 5 from rotating, the positioning mechanism includes positioning protrusions 9 on both sides of the outer wall of the circular plate 5, a positioning groove 10 on the inner wall of the cylindrical body 3 that matches the positioning protrusions 9, and a limiting mechanism inside the cylindrical body 3 to vertically limit the circular plate 5 when it is raised to the top; the lid 2 has a limiting mechanism for the raised circular plate 5. The second limiting mechanism vertically limits the cylindrical body 3 at the top. In use, medical staff pull the lever 8 to lift the circular plate 5 upwards, and at the same time, the positioning protrusion 9 slides upwards along the positioning groove 10. When the circular plate 5 rises to the highest point relative to the cylindrical body 3, it simultaneously lifts the cylindrical body 3 out until it is blocked by the lid 2. Then, the lever 8 is rotated to vertically limit the circular plate 5 through the limiting mechanism. After the lid 2 rises to the top, the cylindrical body 3 is vertically limited by the second limiting mechanism. Then, sharp objects can be thrown through the throwing port 6. The needle can be removed through the needle removal hole 7 by moving from the wide opening to the narrow opening. The sharp object will fall into the sharp object box body 1. After that, the lever 8 is rotated in the opposite direction to reset. Then, after releasing the lever 8, the cylindrical body 3 and the circular plate 5 descend to reset. The bottom of the cylindrical body 3 can be designed on the horizontal surface where the contents exceed the standard. If the cylindrical body 3 and the circular plate 5 cannot descend fully into place, it will remind that the contents need to be replaced.
[0023] Specifically, when the circular plate 5 is located at the bottom of the cylindrical body 3, all the pull rods 8 are located inside the cylindrical body 3; in this embodiment, the top of the pull rod 8 is prevented from being exposed during placement to avoid interfering with the sealing of the sealing cover.
[0024] Specifically, the box cover 2 is also provided with a rotatable sealing cover 11. When the cylindrical body 3 is at the bottom, its top surface is flush with the bottom surface of the sealing cover 11. The sealing cover 11 is provided with an opening 12 that is larger than the outer diameter of the flange 4. In this embodiment, the position of the opening 12 can be adjusted by rotating the sealing cover 11, thereby opening and sealing the top of the cylindrical body 3.
[0025] Specifically, the limiting mechanism includes an arc-shaped groove 13, which connects to the top of the positioning grooves 10 on both sides. The height of the arc-shaped groove 13 is adapted to the thickness of the positioning protrusion 9. In this embodiment, after the circular plate 5 is raised to the highest point, the hand-held lever 8 is rotated to make the positioning protrusion 9 enter the arc-shaped groove 13. After rotating to the end of the arc-shaped groove 13, the circular plate 5 and the cylindrical body 3 can no longer rotate relative to each other, and the circular plate 5 stops after it is higher than the cylindrical body 3.
[0026] Specifically, the second limiting mechanism includes limiting rods 14 located on both sides of the bottom end of the cylindrical body 3 and protruding from the outer wall. The bottom surface of the box cover 2 is provided with an annular blocking part 15. The annular blocking part 15 forms an annular groove 16 on the inner side of the top surface. The annular blocking part 15 is provided with a rod groove 17 corresponding to the limiting rod 14. In this embodiment, by rotating the cylindrical body 3, the limiting rod 14 is driven to rotate along the annular groove 16. Then, when the rotation stops, the cylindrical body 3 stops being vertically limited after it is fully above the box cover 2.
[0027] Specifically, the limiting rod 14 also protrudes into the inner side of the cylindrical body 3; in this embodiment, the circular plate 5 is limited when it descends to the bottom to prevent the circular plate 5 from detaching from the cylindrical body 3.
[0028] Specifically, the top of the pull rod 8 is provided with an indicator mark 18 indicating the position of the positioning protrusion 9; in this embodiment, the position of the positioning protrusion 9 can be easily known from the outside, and thus the position of the limiting rod 14 can be known, which facilitates the control of the position of the positioning protrusion 9 relative to the positioning groove 10 and the position of the limiting rod 14 relative to the rod groove 17.
[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0030] Working principle: In use, rotate the sealing cover 11 so that the opening 12 aligns with the retaining edge 4, fully exposing the retaining edge 4 so that it can be pulled outwards. Then, the medical staff pulls the lever 8 to lift the circular plate 5 upwards. At the same time, the positioning protrusion 9 slides upwards along the positioning groove 10. When the circular plate 5 rises to the highest point relative to the cylindrical body 3, it simultaneously lifts the cylindrical body 3 out of the opening 12 until the limiting rod 14 passes through the rod groove 17 and is blocked by the cover 2. Then, hold the lever 8 and rotate it to make the positioning protrusion 9 enter the arc groove 13. After rotating to the end of the arc groove 13, the circular plate 5 and the cylindrical body 3 can no longer rotate relative to each other, thus driving the limiting rod 14 to move along the groove 10. The annular groove 16 rotates and then stops rotating. The cylindrical body 3 then stops after fully extending above the lid 2, and the circular plate 5 stops after extending above the cylindrical body 3. Sharp objects can then be thrown through the throwing port 6. The needle can be removed by moving from the wide opening to the narrow opening through the needle removal hole 7. The sharp object will fall into the sharp object box body 1. After completion, the pull rod 8 is rotated in the opposite direction to reset. After releasing the pull rod 8, the cylindrical body 3 and the circular plate 5 descend and reset. Then, the sealing cover 11 is rotated to reset the seal. The bottom of the cylindrical body 3 can be designed to be on the horizontal surface where the contents exceed the limit. If the cylindrical body 3 and the circular plate 5 cannot descend fully into place, it indicates that the contents need to be replaced.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
