[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides an anti-stab device for a syringe needle, comprising a support shell 1 and a needle fixing structure. A counterweight 10 is provided at the bottom of the inner cavity of the support shell 1, and the top end of the inner cavity of the support shell 1 is threadedly connected to the needle fixing structure. By providing the counterweight 10, the center of gravity of the anti-stab device can be lowered, thereby improving the stability of the anti-stab device.

[0024] A handle 6 is provided on one side of the support shell 1. The handle 6 facilitates the removal of the device and the syringe inserted into the needle fixing structure. Slide grooves 13 are evenly provided on the bottom of the support shell 1. The inner cavity of the slide groove 13 is movably connected to the sliding rod 5. Limiting grooves 14 are provided on both sides of the inner cavity of the slide groove 13. The inner cavity of the limiting groove 14 is movably connected to the limiting block. The limiting block is fixedly connected to the sliding rod 5. The setting of the limiting groove 14 and the limiting block can prevent the sliding rod 5 from separating from the support shell 1. There is damping between the limiting block and the limiting groove 14. Under the action of external force, the position of the sliding rod 5 in the slide groove 13 can change. When the restriction on the sliding rod 5 is released, the position of the sliding rod 5 in the slide groove 13 can remain unchanged.

[0025] The bottom of the sliding rod 5 is provided with a push-pull slot 7, which allows the user to easily adjust the position of the sliding rod 5. The bottom of the sliding rod 5 is at the same height as the bottom of the support housing 1. Anti-slip pads are fixed to the bottoms of both the support housing 1 and the sliding rod 5. The provision of anti-slip pads increases the friction between the device and the support platform, improving the stability of the device. The anti-slip pads can be made of rubber.

[0026] From the above description of the support shell 1, it can be seen that when the device is in use, the support area of ​​the device can be changed by changing the position of the sliding rod 5 in the sliding groove 13, thereby improving the stability of the device, and when the device is stored, the sliding rod 5 can be hidden in the inner cavity of the sliding groove 13, reducing the space occupied by the device and facilitating the storage of the device.

[0027] The needle-fixing structure includes a fixing shell 2 that fits with the support shell 1. The top of the inner cavity of the support shell 1 is provided with an internal thread 12, and the outer wall of the top of the fixing shell 2 is provided with an external thread 11 that fits with the internal thread 12. The inner diameter of the lower end of the fixing shell 2 is adapted to the inner diameter of the support shell 1. The external thread 11 is provided on the lower end of the fixing shell 2. The outer diameter of the upper end of the fixing shell 2 is the same as the outer diameter of the support shell 1. Through the arrangement of the internal thread 12 and the external thread 11, the support shell 1 and the needle-fixing structure can be quickly fixed or separated, facilitating cleaning of the needle-fixing structure.

[0028] A rotating rod 3 is movably connected to one side of the side wall of the fixed shell 2. There is damping between the rotating rod 3 and the side wall of the fixed shell 2. Under the action of an external force, the rotating rod 3 can rotate, releasing the restriction on the rotating rod 3, and the position of the rotating rod 3 can remain unchanged. The bottom of the rotating rod 3 is fixedly connected to one side of the top of the opening and closing cover 8. The top of the rotating rod 3 is fixedly connected to a rotating handle. Through the setting of the rotating rod 3, the user can drive the rotating rod 3 to rotate by rotating the handle. When the rotating rod 3 rotates, it can drive the opening and closing cover 8 fixedly connected thereto to rotate. The opening and closing cover 8 and the bottom of the fixed shell 2 can overlap or stagger. A sealing gasket is fixedly connected to the top of the opening and closing cover 8. Through the setting of the sealing gasket, the sealing between the opening and closing cover 8 and the bottom of the fixed shell 2 can be increased. The sealing gasket can be made of rubber.

[0029] A needle wrapping block 4 is fixedly connected to the top of the inner cavity of the fixed shell 2. When the opening and closing cover 8 seals the bottom of the fixed shell 2, a liquid absorbing block 9 is placed in the cavity between the opening and closing cover 8 and the needle wrapping block 4. The thickness of the needle wrapping block 4 is no greater than the length of the needle. With this configuration, when the device is in use, the syringe needle can be inserted into the needle wrapping block 4. When the syringe needle is fully inserted into the needle wrapping block 4, the distal end of the needle can be inserted into the liquid absorbing block 9. The liquid absorbing block 9 absorbs the residual liquid in the needle, preventing it from splashing when the syringe is withdrawn, thereby improving safety. The thickness of the needle wrapping block 4 can be set according to needs and is not limited here.

[0030] In some embodiments of the present application, the needle wrapping block 4 is made of silicone, the liquid absorption block 9 is made of sponge, and the liquid absorption block 9 is provided with a sterilization coating, which can sterilize the needle and further improve the safety when the needle is removed. The sterilization coating can be sterilized with silver ions.

[0031] In summary, when the syringe needle puncture prevention device is used, the medical staff places the device in a suitable position and adjusts the position of the sliding rod 5 in the slide groove 13 as needed to improve the stability of the device when in use. When the device is in use, the medical staff inserts the used syringe needle into the needle wrapping block 4. When the needle is fully inserted, the end of the needle extends into the liquid absorption block 9. The liquid absorption block 9 absorbs the residual liquid in the needle to prevent the residual liquid in the needle from splashing when the syringe is pulled out, thereby improving the safety of needle extraction. Moreover, after the device is used, when the liquid absorption block 9 needs to be replaced, the medical staff rotates the fixed shell 2 to separate the fixed shell 2 from the supporting shell 1, and then rotates the rotating rod 3. The rotating rod 3 drives the opening and closing cover 8 fixedly connected thereto to rotate until the opening and closing cover 8 is completely separated from the bottom of the fixed shell 2. The liquid absorption block 9 can be separated from the fixed shell 2 under the action of gravity, and the liquid absorption block 9 can be replaced. Moreover, after the device has been used for a long time, the needle wrapping block 4 also needs to be replaced. When the needle wrapping block 4 can no longer be used, the user only needs to replace the needle fixing structure, and the support shell 1 can continue to be used.
