[0002] Analgesia pumps are medical devices that relieve pain through a medication route more tailored to the patient. Currently, analgesia pumps are used intravenously or epidurally for analgesia. Currently, there are no patient-controlled analgesia devices for nasal sprays. Therefore, developing a patient-controlled analgesia device that can be used with a nasal spray bottle would better address the current medication regimen issues faced by patients.

[0003] When using the existing self-controlled analgesia pump device, the patient mainly controls the medication according to his or her own pain sensation to relieve pain. The overall operation is relatively convenient, and it can quickly and timely relieve the patient's pain, and has high use value.

[0055] according to Figure 1 、 Figure 3 、 Figure 6 and Figure 9 As shown, a replacement mechanism 13 is inserted into the inner side of the analgesic pump body 1;

[0056] The replacement mechanism 13 includes a sliding bracket 1301, which is inserted into the interior of the analgesic pump body 1. Two clamping brackets 1302 are installed on the top of the sliding bracket 1301. The infusion hose 303 is clamped inside the two clamping brackets 1302.

[0057] according to Figure 1 As shown, a display screen 14 is provided on the surface of the analgesic pump body 1, and a plurality of control buttons 15 are provided on the surface of the analgesic pump body 1. Through the setting of the display screen 14 and the control buttons 15, the current operating parameters of the device can be displayed and the operating parameters can be adjusted at the same time.

[0058] Working principle: First, the battery is put into the power supply module 7 to supply energy to the electrical equipment in the device to ensure the normal operation of the device. Then, the heart rate sensor 804, blood pressure sensor 805 and skin electrical induction sensor 806 are worn on the patient's wrist or arm through two elastic bands 807.

[0059] During the data evaluation phase, the heart rate sensor 804, blood pressure sensor 805 and skin electrical induction sensor 806 first detect and collect the patient's physiological data, and transmit the data to the integrated module 801 via the connecting wire 802. The integrated module 801 then transmits the data to the processor 6 for analysis and processing.

[0060] During the nasal spray treatment phase, first, the atomizing nozzle 304 is inserted into the patient's nasal cavity, and then the control button 15 is pressed to start the device. The processor 6 controls the servo electric cylinder 402 to start according to the data. The servo electric cylinder 402 pushes the starting pressure frame 403 downward, causing the nasal spray bottle 301 to be pressurized to spray the nasal spray. The nasal spray is then transported from the infusion hose 303 to the atomizing nozzle 304 for spraying, and the patient is given medication treatment.

[0061] In the automatic adjustment stage, first, the pain tolerance detection mechanism 8 continuously detects and collects the patient's physiological data, and the processor 6 monitors and analyzes the physiological data. If the patient's pain tolerance is high, the processor 6 controls the servo motor 503 to start, and the servo motor 503 drives the connecting shaft 502 to rotate, causing the cam 504 to rotate and squeeze the protrusion 508, so that the sliding plate 507 slides on the fixed rod 505, and squeezes the first spring 506 to shrink it. When the pressure block 509 reaches the top of the infusion hose 303 and applies pressure to it, the dosage is reduced. On the contrary, if the patient's pain tolerance is low, the processor 6 controls the servo electric cylinder 402 to increase the thrust, so that the dosage of the nasal spray bottle 301 is increased.

[0062] During the spray replacement phase, first, the acrylic cover 11 is moved to force the hinge 10 to drive the acrylic cover 11 to rotate and open. Next, the pull ring 906 is pulled to make the end plate 904 pull the telescopic rod 902 and the second spring 903 to contract. At this time, the used nasal spray bottle 301 is removed by screwing. Then, the atomizing nozzle 304 is removed from one end of the infusion hose 303. The pull ring 1304 is pulled to force the sliding bracket 1301 to slide outward, and the infusion hose 303 clamped in the two clamping brackets 1302 is removed from the analgesic pump body. The analgesic pump body 1 is taken out, and the nasal spray bottle 301, the infusion hose 303 and the atomizing nozzle 304 are cleaned and replaced. After the replacement is completed, the replaced infusion hose 303 is clamped in the two clamping frames 1302, and the replacement mechanism 13 is reinserted into the analgesic pump body 1. The replaced nasal spray bottle 301 is screwed and installed at the connecting end 302, and then the pull ring 906 is loosened to make the second spring 903 rebound, and cooperate with the telescopic rod 902 to push the end plate 904 to reset, prompting the second limit frame 905 to clamp the nasal spray bottle 301.

[0063] By following the above-described procedures, you can complete the use of the intelligently adjustable nasal spray self-controlled analgesia pump device based on pain tolerance assessment.
