[0002] A pain pump is a fluid infusion device that maintains a steady concentration of medication in the blood, which can help achieve better pain relief with less medication.

[0003] By pre-burying the needle of the analgesic pump in the human body and connecting it to the analgesic pump through a pipeline, the analgesic pump transports the medicine into the human body through the pipeline to relieve the pain.

[0004] In the prior art, the needle is pre-buried in the human body, and the needle and the pipeline are fixed to the human body through a patch, and the drug is delivered through an analgesic pump connected to the pipeline. However, the infusion tube is only fixed to the human body through a patch, which causes the infusion tube and the needle to shake once the analgesic pump is pulled during use. The needle may shake or become loose, which is not conducive to the patient's recovery. Therefore, we propose an embedded analgesic pump. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The embodiment of the present application provides an embedded analgesic pump to solve the problem that when the analgesic pump is in use, once the analgesic pump body 1 is pulled, causing the infusion tube 101 to be pulled, the infusion tube 101 and the needle 102 will shake, and the needle 102 will shake or loosen, which is not conducive to the patient's recovery. When the infusion tube 101 is pulled to move, the infusion tube 101 moves and pulls the limiting seat 502 to move. Under the reverse push of the limiting seat 502, the pulling of the infusion tube 101 is limited to prevent the movement of the infusion tube 101 and the needle 102 from loosening. When the limiting seat 502 moves, it pushes the squeezing seat 6 to move downward. At this time, the squeezing seat 6 squeezes the infusion tube 101, further limits the infusion tube 101, prevents the needle 102 from loosening, ensures normal use, and facilitates patient recovery.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model embodiment discloses an embedded analgesic pump.

[0028] According to the attached Figure 1-4 As shown, it includes an analgesic pump body 1, an infusion tube 101 and a needle 102. The end of the analgesic pump body 1 is plugged with the infusion tube 101, and the other end of the infusion tube 101 is fixedly connected to the needle 102. The analgesic pump body 1 is filled with an analgesic agent, which is connected to an injection head in a human body through the infusion tube 101 and the needle 102, and the agent in the analgesic pump body 1 is injected into the human body to relieve pain;

[0029] The needle 102 is inserted into the first patch 2, the first patch 2 is attached to the human body, the second patch 3 is attached to the human body, the second patch 3 is fixedly connected to the fixing seat 4, the needle 102 is stably placed on the human body through the first patch 2, the fixing seat 4 is stably placed on the human body through the second patch 3, and the fixing seat 4 is provided with:

[0030] The limiting unit includes a connecting seat 5 and a limiting seat 502. The connecting seat 5 is fixedly connected to the top end surface of the fixing seat 4. The limiting seat 502 is fitted with the connecting seat 5. The limiting unit limits the infusion tube 101 through the connecting seat 5 and the limiting seat 502. When the infusion tube 101 is pulled to move, the infusion tube 101 moves to pull the limiting seat 502 to move. Under the reverse push of the limiting seat 502, the infusion tube 101 is limited to be pulled to prevent the infusion tube 101 from moving and pulling the needle 102, so that the needle 102 is loosened;

[0031] The extrusion unit includes an extrusion seat 6 and a limiting rod 601. The limiting rod 601 is fixedly connected to the fixing seat 4. The extrusion seat 6 is slidably connected to the outer peripheral wall of the limiting rod 601. The extrusion unit squeezes and fixes the infusion tube 101 through the extrusion seat 6. When the limiting seat 502 moves, the extrusion seat 6 is pushed to move downward. At this time, the extrusion seat 6 squeezes the infusion tube 101, further limits the infusion tube 101, and prevents the needle 102 from loosening.

[0032] A positioning sticker 401 is provided on the fixing seat 4 , and the positioning sticker 401 is in contact with the outer wall of the infusion tube 101 . By passing the infusion tube 101 through the positioning sticker 401 , the infusion tube 101 is in contact with the fixing seat 4 under the action of the positioning sticker 401 .

[0033] A connecting frame 501 is fixedly connected to the fixing seat 4 , and two sides of the connecting frame 501 are fixedly connected to two ends of the connecting seat 5 .

[0034] A slide bar 503 is slidably connected to the inner wall of the connecting frame 501, and one end of the slide bar 503 is fixedly connected to the limit seat 502. The infusion tube 101 is then passed through the connecting seat 5 and the limit seat 502. When an external force pulls the infusion tube 101, the infusion tube 101 moves and pushes the limit seat 502 to move, so that the limit seat 502 drives the slide bar 503 to slide on the connecting frame 501.

[0035] The outer wall of the slide bar 503 is sleeved with a spring 504, and the two sides of the spring 504 are fixedly connected to the limit seat 502 and the connecting frame 501 respectively. When the limit seat 502 moves, the spring 504 is squeezed, and the rebound of the spring 504 exerts a reverse force on the infusion tube 101 to prevent the infusion tube 101 from being pulled.

[0036] The other end of the slide bar 503 passes through the connecting frame 501 and is fixedly connected to the pushing seat 505 , and the movement of the slide bar 503 causes the pushing seat 505 to move accordingly.

[0037] The inclined surface of the pushing seat 505 is in contact with the pressing seat 6 .

[0038] Both sides of the extrusion seat 6 are fixedly connected with a sliding seat 602, and the sliding seat 602 is slidably connected to the outer peripheral wall of the limiting rod 601. At this time, the pushing seat 505 moves to push the extrusion seat 6 to move. At this time, the extrusion seat 6 drives the sliding seat 602 to slide along the limiting rod 601, so that the extrusion seat 6 squeezes the infusion tube 101 and limits the infusion tube 101. At this time, the infusion tube 101 cannot be pulled, thereby preventing the infusion tube 101 from driving the needle 102 to move, protecting the needle 102, and preventing the needle 102 from loosening and being unable to be used normally.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
