[0022] In specific implementation,

[0023] Referring to Figures 1-3 It can be known that when the analgesic pump filter is used, the filter material inside is prone to edge lifting, so that the effect of the filter is poor when used. The butt joint groove 11 inside the filter plate 9 is clamped and connected with the positioning column 13, so that the rubber clamping block 14 on the surface of the positioning column 13 can limit the clamped filter plate 9, so that the filter plate 9 can be preliminarily stabilized. Then, the filter cover plate 2 is connected with the filter casing 1, so that the compression ring 7 at the bottom of the filter cover plate 2 can be connected with the limit ring 5 inside the filter casing 1, and the limit pin 15 at the bottom of the compression ring 7 can be clamped with the butt joint hole 12 inside the filter plate 9, so that the analgesic pump filter can be more stably limited to the filter plate 9 inside, thereby avoiding edge lifting of the filter plate 9 when used, so that the analgesic pump filter can have better filtering effect when used.

[0025] In particular implementation,

[0026] As can be seen from Figure 1 、 Figure 2 and Figure 4 , when the analgesic pump filter is docked with the pipeline, it is easy to be loosened after being pulled, and then the analgesic pump filter is more inconvenient to connect with the pipeline. The rotating ring 20 can be rotated to rotate the connecting screw rod 19 when the rotating ring 20 rotates, so that the screw rod 19 can push the connected clamping ring 18, so that the clamping ring 18 can cooperate with the fixed ring 17 arranged, so that the connected pipeline can be quickly clamped, and the clamping ring 18 can move inside the docking ring 16 through the stabilizing rod 21, so that the clamping ring 18 can have better stability effect when in use, so that the analgesic pump filter can have better anti-loosening and falling effect when in use.

[0027] In summary, the analgesic pump filter can effectively prevent solid particles, bacteria, viruses and the like in the medicine from entering the patient's body when in use, and is suitable for postoperative, cancer pain, labor analgesia and the like. It improves patient comfort, and the docking groove 11 inside the filter plate 9 is clamped and docked with the positioning column 13, so that the rubber clamping block 14 arranged on the surface of the positioning column 13 can limit the clamped filter plate 9, so that the filter plate 9 can be preliminarily stabilized, and then the filter cover plate 2 is docked with the filter housing 1, and the limiting pin 15 arranged at the bottom of the compression ring 7 can be clamped with the docking hole 12 inside the filter plate 9, so that the analgesic pump filter can be more stably limited with the filter plate 9 inside, thereby avoiding the filter plate 9 from being warped when in use, so that the analgesic pump filter can have better filtering effect when in use.
