[0026] An intelligent dressing change device for burn patients disclosed by the present invention is mainly applied to the scenario where the existing intelligent dressing change devices cannot intelligently control the dosage of medicine according to the severity of burns in different parts.

[0027] Referring to Figures 1-7 , an intelligent dressing change device for burn patients includes a housing 1. A support 3 is bolted to the inner wall of the housing 1. A first sponge pad 4 is bolted to the inner wall of the support 3. And a support 5 is bolted to the bottom inner wall of the housing 1.

[0029] The fixing and anti-deviation module 9 includes a contact plate 901. Heart rate monitors 10 are arranged on both the contact plate 901 and the second sponge pad 6.

[0030] Specifically, when the patient needs to change the dressing, let the patient put the arm into the housing 1, with the forearm fitting on the first sponge pad 4 and the wrist fitting on the second sponge pad 6. Use the fixing and anti-deviation module 9 to fix the fixing frame 7 on the support 5 to fix the patient's arm; use the first camera 805 and the second camera 806 on the intelligent drug delivery module 8 to locate the burn area of the patient. After uncovering the dressing, use the infrared camera 822 to divide the severity of the burn area into zones, and then use the intelligent drug delivery module 8 to perform intelligent drug delivery to the burn area; the device can use the intelligent drug delivery module 8 to accurately locate the burn area of the patient and use multiple cameras for cross-comparison, so as to complete the zoning of the severity of the burn area, enabling the device to intelligently control the dosage of medicine at the burn location of the patient, improving the treatment and recovery effect.

[0031] Referring to Figure 3 , Figure 4 and Figure 5, in a preferred embodiment, two symmetrical supports 801 are bolted to the inner walls on both sides of the housing 1. Two crossbars 802 and lead screws 803 are rotatably connected to the two supports 801 on the same side through bearings respectively. A motor 804 is bolted to the inner wall of the housing 1. The output end of the motor 804 is connected to one side of the lead screw 803 through a coupling. Moving blocks 811 are arranged outside both the lead screw 803 and the crossbar 802; A same threaded rod 812 is rotatably connected to the opposite sides of the two moving blocks 811 through bearings. A guide rod 813 is arranged outside the threaded rod 812. The guide rod 813 is bolted to the opposite sides of the two moving blocks 811. A movable seat 814 is arranged outside the threaded rod 812 and the guide rod 813. A motor 816 is bolted to the upper side of the moving block 811 on the same side as the lead screw 803. The output end of the motor 816 is connected to a gear 817 through a coupling. An external tooth ring 815 is bolted to the outside of the threaded rod 812. The external tooth ring 815 meshes with the gear 817; A hydraulic rod 818 is bolted to the bottom of the movable seat 814. The output end of the hydraulic rod 818 is bolted to an isolation cover 819. A motor 820 is bolted to the inner wall of the top of the isolation cover 819. The output end of the motor 820 is connected to a mounting plate 821 through a coupling. The upper side of an infrared camera 822 is bolted to the bottom of the mounting plate 821. A round hole is formed in the mounting plate 821; The inner wall of the round hole is bolted to the outside of a spray head 823. A lower cavity is formed in the upper side of the housing 1. A delivery pipe 809 is arranged in the fine hole. A medicine storage tank 807 is bolted to the upper side of the housing 1. A filling port 808 is arranged on the medicine storage tank 807. One end of the delivery pipe 809 is bolted to the medicine storage tank 807, and the other end is bolted to the upper side of the spray head 823. A pump 810 is bolted to the outside of the medicine storage tank 807. The output end of the pump 810 is connected to the delivery pipe 809 through a thin pipe. A robotic arm 824 is bolted to the bottom of the mounting plate 821.

[0032] Specifically, after the patient's arm is fixed in the housing 1, the first camera 805 and the second camera 806 are activated to locate the dressing on the patient's burn site. Then, the motor 804 and the first motor 816 are activated. The motor 804 drives the lead screw 803 to rotate, causing the moving block 811 to drive the movable seat 814 to move horizontally. The first motor 816 drives the gear 817 meshing with the external gear ring 815 to rotate, causing the movable seat 814 to move longitudinally. The hydraulic rod 818 and the robotic arm 824 are activated, enabling the robotic arm 824 to clamp a corner of the dressing and lift the dressing as the movable seat 814 moves. During this process, the heart rate monitor 10, the first camera 805, and the second camera 806 continuously monitor the patient's heart rate changes and the tremors of the arm muscles, so that the robotic arm 824 can control the force and speed of lifting the dressing. After the dressing is lifted, the infrared camera 822 is activated. The infrared camera 822 divides the temperature distribution of the burn location into zones. Then, the pump 810 is activated. The pump 810 transports the medicament in the medicine storage tank 807 through the delivery pipe 809 into the nozzle 823, causing the nozzle 823 to spray different amounts of medicine onto the zoned burn sites.

[0033] In a specific application scenario, the intelligent drug delivery module 8 is mainly applicable to the intelligent drug delivery link in the intelligent drug delivery process. That is, the intelligent drug delivery module 8 uses the first camera 805, the second camera 806, and the heart rate monitor 10 to enable the device to continuously monitor the patient's heart rate changes and the tremors of the arm muscles during the process of changing the dressing on the patient's burn site, real-time monitor the patient's pain response and skin condition, and automatically adjust the dressing change speed, ensuring both efficiency and the patient's comfort.

[0034] Refer to Figure 6 and Figure 7, in a preferred embodiment, two symmetric circular openings are formed in the fixing frame 7, and a pressing rod 903 is slidably connected to each of the circular openings. Springs 904 are wound around the outer portions of the two pressing rods 903. One end of each spring 904 is bolted to the outer portion of the pressing rod 903 on the same side, and the other end of each spring is bolted to the upper side of the fixing frame 7. Moreover, the bottoms of the two pressing rods 903 are bolted to the upper side of the contact plate 901; two symmetric notches are formed in the support two 5, and a latch 905 is slidably connected to each of the notches. The upper sides of the latches 905 are bolted to the bottom of the fixing frame 7, and fixing seats 906 are inserted into the outer portions of the latches 905. The upper sides of the fixing seats 906 are bolted to the outer portion of the support two 5; three circumferentially equally spaced cutting grooves 907 are formed at the bottoms of the two fixing seats 906, and a locking rod 908 is slidably connected to each of the cutting grooves 907. Annular grooves 910 are formed in the two latches 905, and the inner walls of the annular grooves 910 are clamped to the outer portions of the locking rods 908. Moreover, a short shaft 909 is bolted to the bottom of each locking rod 908; the outer portions of the two latches 905 are slidably connected to rotating frames 911. The upper sides of the rotating frames 911 are rotatably connected to the bottoms of the fixing seats 906 on the same side through bearings. Three circumferentially equally spaced curved surface grooves 912 are formed in each of the rotating frames 911, and the inner walls of the curved surface grooves 912 are slidably connected to the outer portions of the short shafts 909 on the same side. Moreover, a torsion spring 902 is bolted to the inner wall of each rotating frame 911, and one end of the torsion spring 902 away from the rotating frame 911 is bolted to the outer portion of the fixing seat 906 on the same side.

[0035] Specifically, after the patient's wrist is placed on the sponge pad two 6, the latch 905 on the fixing frame 7 is inserted into the fixing seat 906 and gently pressed, so that the latch 905 pushes the locking rod 908 away, enabling the latch 905 to be completely inserted into the rotating frame 911. Under the torsion of the cross bar 802, the locking rod 908 is inserted into the annular groove 910, thereby locking the latch 905 and fixing the fixing frame 7 on the sponge pad two 6. At this time, the contact plate 901 is closely attached to the patient's wrist under the elastic force of the spring 904, enabling the heart rate monitor 10 to contact the patient's skin.

[0036] In a specific application scenario, the fixing and anti-deviation module 9 is mainly applicable to the fixing and anti-deviation link in the fixing and anti-deviation process, that is, the fixing and anti-deviation module 9 uses the annular groove 910 and the locking rod 908 to stably control the device after the patient puts the arm into the housing 1, thereby reducing the probability of the situation where the patient moves the arm due to pain, resulting in inaccurate dressing change positions, and effectively improving the efficiency of dressing change.

[0037] An intelligent dressing change method for burn patients, using an intelligent dressing change device for burn patients as described above, includes the following steps:

[0038] Step 1: When the patient needs dressing change, let the patient insert the arm into the housing 1, with the forearm fitting against the first sponge pad 4 and the wrist fitting against the second sponge pad 6. Use the fixed anti-deviation module 9 to fix the fixing frame 7 on the second bracket 5 to fix the patient's arm. (After placing the patient's wrist on the second sponge pad 6, insert the pin 905 on the fixing frame 7 into the fixing seat 906 and press it gently, so that the pin 905 pushes the locking rod 908 away, allowing the pin 905 to be fully inserted into the rotating frame 911. Under the torsion of the cross bar 802, the locking rod 908 is inserted into the annular groove 910, thus locking the pin 905 and fixing the fixing frame 7 on the second sponge pad 6. At this time, the contact plate 901 is closely attached to the patient's wrist under the elastic force of the spring 904, enabling the heart rate monitor 10 to contact the patient's skin.)

[0039] Step 2: Use the first camera 805 and the second camera 806 on the intelligent drug delivery module 8 to locate the patient's burn area. After uncovering the dressing, use the infrared camera 822 to divide the severity of the burn area, and then use the intelligent drug delivery module 8 to perform intelligent drug delivery to the burn area. (After the patient's arm is fixed in the housing 1, start the first camera 805 and the second camera 806 to locate the dressing on the patient's burn area. Start the motor 804 and the first motor 816. The motor 804 drives the lead screw 803 to rotate, causing the moving block 811 to drive the movable seat 814 to move horizontally. The first motor 816 drives the gear 817 meshing with the external gear ring 815 to rotate, causing the movable seat 814 to move vertically. Start the hydraulic rod 818 and the robotic arm 824, so that the robotic arm 824 can clamp a corner of the dressing and lift the dressing along with the movement of the movable seat 814. During this process, the heart rate monitor 10, the first camera 805 and the second camera 806 continuously monitor the patient's heart rate changes and the tremors of the arm muscles, so as to enable the robotic arm 824 to control the force and speed of lifting the dressing. After the dressing is lifted, start the infrared camera 822. The infrared camera 822 divides the temperature distribution of the burn location. Start the pump 810. The pump 810 transports the medicine in the medicine storage tank 807 through the delivery pipe 809 into the nozzle 823, so that the nozzle 823 sprays different amounts of medicine onto the divided burn areas respectively.)
