Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a contamination-proof syringe needle safety separation tool box. Background Technology

[0002] Sharps containers are specially designed for the safe disposal of medical sharps waste. Their design prioritizes protection against punctures and leaks, safeguarding healthcare workers from needlestick injuries and other infection risks. They are typically made of sturdy plastic and feature specific safety characteristics such as a one-way inlet (making it difficult to remove once a sharps item is inserted), an overflow protection mechanism, and a stable design to prevent tipping. In practice, after procedures such as injections or blood draws, healthcare workers use the sharps container to separate the syringe needle from the syringe tubing, placing the needle into the container. When the container is full of needles, it is sealed and sent to a designated location for incineration or other environmentally friendly disposal methods, ensuring no environmental pollution or threat to the health of others.

[0003] See Figure 1 Existing syringes consist of a needle and a barrel. The needle includes a plunger (1), a shaft (2), and a tip (3), while the barrel includes a piston (4), an empty barrel (5), and a nipple (6). In clinical practice, some procedures require drawing medication and then removing the needle to continue using the syringe barrel. For example, intravenous injection of medication from an indwelling catheter requires drawing the medication first and then removing the needle for injection. Currently, nurses manually separate the needles, but this manual separation process carries the risk of needle pricks for medical staff, which does not meet occupational safety requirements.

[0004] Chinese patent document CN219251243U discloses a sharps box for quick needle removal, comprising: a box body, which is a hollow cylindrical structure; a box cover, installed on the top of the box body, the surface of which has a separation port for separating the needle from the syringe barrel in various types of syringes; and a circular sealing cap, rotatably connected to the box cover for sealing and allowing the separation port on the box body to be exposed; wherein, the separation port includes a prismatic opening and a groove, the prismatic opening and the groove are interconnected, and the axes of the prismatic opening and the groove are on the same sub-line, the prismatic opening and the groove are respectively used for separating the needle from the syringe barrel of two different types of syringes. The defects and shortcomings of this quick needle removal sharps box are: the sharps box engages the needle plug 1 of the needle with the prismatic opening or the groove before separating the needle from the barrel, during which the tip 6 of the barrel is at risk of being contaminated by the sharps box, affecting subsequent use.

[0005] Therefore, there is an urgent need to provide a contamination-proof syringe needle safety separation tool box. Utility Model Content

Detailed Implementation

[0035] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 2 The orientation is used as a reference.

[0036] Example 1:

[0037] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment provides a contamination-proof syringe needle safety separation tool box, including a box body 7 and a box cover 8. The box body 7 has a hollow cylindrical structure, and the box cover 8 is provided on the open opening at the upper end of the box body 7.

[0038] The lid 8 has a needle fixing hole 9 for the needle tip 3 and needle shaft 2 to pass through. The inner wall of the lid 8 is provided with a needle fixing device 11 corresponding to the area of ​​the needle fixing hole 9. The needle fixing device 11 can clamp and fix the needle shaft 2 for separating the needle from the syringe body. The lid 8 also has a needle insertion port 10 on the side of the needle fixing hole 9 for inserting the separated needle.

[0039] The anti-contamination syringe needle safety separation tool box of this embodiment uses a needle fixing device to clamp and fix the needle shaft 2 to assist in separating the syringe needle from the syringe barrel. This not only prevents the needle from pricking the operator, but also avoids contaminating the syringe barrel nipple 6 during the separation process. As a result, the operator can first draw the medication, then remove the needle, and finally inject the medication intravenously through the patient's indwelling needle.

[0040] Preferably, the needle fixing device 11 includes a slider 13 and a slider driving assembly 16. The inner wall surface of the cover 8 includes an inner top surface and an inner side surface. The inner top surface of the cover 8 extends downward in the vertical direction and then extends horizontally to form an L-shaped extension 12. The L-shaped extension 12 and the inner top surface of the cover 8 form a sliding groove. The slider 13 is slidably disposed in the sliding groove. The slider 13 has a first abutment hole 14. The axial direction of the first abutment hole 14 is parallel to the axial direction of the needle fixing hole 9. The horizontal part of the L-shaped extension 12 has a second abutment hole 15 corresponding to the area of ​​the needle fixing hole 9. The slider driving assembly 16 is disposed on the inner wall surface of the cover 8 and is drivenly connected to the slider 13. When the needle tip 3 and the needle shaft 2 of the needle pass through the needle fixing hole 9, the first abutment hole 14 and the second abutment hole 15, the slider driving assembly 16 can drive the slider 13 to move, so that the needle fixing hole 9 and the second abutment hole 15 are misaligned with the first abutment hole 14, thereby clamping and fixing the needle shaft 2.

[0041] It should be noted that when the needle fixing hole 9 and the second abutment hole 15 coincide with the first abutment hole 14, the needle tip 3 and the needle shaft 2 can freely enter and exit the needle fixing hole 9. When the needle fixing hole 9 and the second abutment hole 15 are misaligned with the first abutment hole 14, the needle fixing hole 9 and the second abutment hole 15 cooperate with the first abutment hole 14 to abut the needle shaft 2, restricting the needle from moving vertically.

[0042] Preferably, the inner wall surfaces of the needle fixing hole 9, the first abutment hole 14, and the second abutment hole 15 in this embodiment are provided with patterns. The purpose of providing patterns is to increase the friction between the needle fixing hole 9, the first abutment hole 14, the second abutment hole 15 and the needle shaft 2, so as to achieve stable clamping of the needle.

[0043] See Figure 6In this embodiment, the slider drive assembly 16 is preferably a lead screw drive assembly, which includes a first servo motor 17, a lead screw mounting bracket 18, a lead screw 19, and a transmission nut 20. The lead screw mounting bracket 18 is disposed on the inner wall of the cover 8, and the lead screw 19 is rotatably disposed inside the lead screw mounting bracket 18. The output shaft of the first servo motor 17 is connected to the end of the lead screw 19, and the transmission nut 20 is sleeved on the periphery of the lead screw 19 and connected to the slider 13.

[0044] In use, the first servo motor 17 drives the lead screw 19 to rotate, and the lead screw 19 drives the transmission nut 20 and the slider 13 to move axially, thereby causing the first abutment hole 14 on the slider 13 to coincide with or be misaligned with the needle fixing hole 9.

[0045] Preferably, the anti-contamination syringe needle safety separation sharps box of this embodiment further includes a control circuit board and a button (not shown in the figure). The control circuit board is fixedly disposed on the inner wall surface of the box cover 8, and the button is disposed on the outer surface of the box cover 8. The button is electrically connected to the control circuit board, and the control circuit board is electrically connected to the slider drive assembly 16 to control the operation of the slider drive assembly 16.

[0046] It should be noted that the anti-contamination syringe needle safety separation tool box of this embodiment also includes a battery. The battery is electrically connected to the control circuit board and the slider drive assembly 16 respectively, and is used to supply power to each electrical component.

[0047] Preferably, the anti-contamination syringe needle safety separation tool box of this embodiment also includes a disposable inner barrel (not shown in the figure). The disposable inner barrel is disposed inside the box body 7, and a needle inlet is provided on the upper part of the disposable inner barrel corresponding to the needle insertion port 10 on the box cover 8.

[0048] The purpose of including the disposable inner container is to save resources and reduce the cost of using the contamination-proof syringe needle safety separation toolbox. Specifically, when the disposable inner container is full of needles, the operator can remove them from the container 7, reseal it, and send it to a designated location for disposal. The container 7 and the lid 8 are then sterilized and reused.

[0049] Preferably, the cover 8 extends outward from the needle insertion port 10 to form a funnel-shaped structure. The upper end of the funnel-shaped structure is open, and the lower end is connected to the needle insertion port 10 to guide the separated needles into the needle insertion port 10.

[0050] The usage process of the anti-contamination syringe needle safety separation sharps box in this embodiment is as follows:

[0051] First, the operator inserts the needle tip 3 and needle shaft 2 of the syringe needle into the needle fixing hole 9 of the box cover 8, and then passes them through the first abutment hole 14 and the second abutment hole 15 in sequence.

[0052] Next, the slider drive assembly 16 is activated via the button and control circuit board. The slider drive assembly 16 drives the slider 13 to move, causing the needle fixing hole 9 and the second abutment hole 15 to misalign with the first abutment hole 14. This abuts the needle shaft 2, limiting the needle's vertical movement through friction. Then, the operator holds the syringe in one hand and pinches the needle's plug 1 with the other, causing relative displacement between the two in the circumferential and / or axial directions, thereby removing the needle. Finally, the slider drive assembly 16 is activated via the button and control circuit board. The slider drive assembly 16 drives the slider 13 to move in the opposite direction, causing the needle fixing hole 9, the second abutment hole 15, and the first abutment hole 14 to align. After removing the needle from the needle fixing hole 9, it is placed into the needle insertion port 10 of the cover 8.

[0053] Example 2:

[0054] This embodiment provides another type of anti-contamination syringe needle safety separation tool box. The difference from embodiment 1 is that the slider drive assembly 16 in this embodiment is a gear and rack drive assembly.

[0055] The rack and pinion drive assembly includes a second servo motor, a rack mounting bracket, a rack, and a gear. The rack mounting bracket is disposed on the inner wall of the cover 8, the rack is slidably disposed inside the rack mounting bracket, the body of the second servo motor is disposed on the cover 8, the output shaft of the second servo motor is fitted with a gear, the gear meshes with the rack, and the rack is connected to the slider 13.
