During the process of applying the ointment with a cotton swab, the cotton swab will directly contact the patient's skin. If the strength is not properly controlled, it is easy to cause secondary damage to the patient. In addition, the peeled off skin on the patient's burn area is attached to the patient's skin surface, affecting the absorption of the medicine on the burn area, which will have a certain impact on the patient's recovery. The present invention provides a medical large-area burn ointment application device to solve the above problems. Summary of the invention

[0036] Furthermore, a sliding plate 39 capable of closing the medicine outlet groove 38 is provided inside the medicine outlet groove 38 for sliding sealing.

[0037] Furthermore, a plurality of second slots 57 are opened at the bottom of the first support frame 10, and a second rotating shaft 58 is fixedly arranged inside the second slot 57. A rotating rod 59 is rotatably arranged on the second rotating shaft 58. A third rotating shaft 60 is rotatably arranged on one end of the rotating rod 59 away from the second rotating shaft 58, and a clamping claw 61 is fixedly arranged on one side of the third rotating shaft 60 away from the first support frame 10.

[0038] Working principle: Initially, the patient is asked to crawl on the bed with the burned part facing upwards, and then the first support frame 10 is fixed above the burned part, and the clamping claw 61 is fixed to the edge of the bed to ensure that the first support frame 10 does not shake during the working process. The sliding plate 39 ensures that the medicine squeezing channel 36 and the medicine outlet groove 38 are connected to each other.

[0039] Observe the size of the patient's burn area, open the first barrel cover 32 and fill a sufficient amount of ointment into the first cavity 31 inside the medicine squeezing barrel 30. After filling, close the first barrel cover 32, and then start the telescopic motor 34 to drive the first slider 33 to squeeze the ointment inside the medicine squeezing barrel 30. When the ointment passes through the medicine squeezing channel 36 and reaches the inside of the medicine outlet groove 38, turn off the telescopic motor 34.

[0040] Slide the second support frame 12 and the support plate 13 so that the support tube 14 is opposite to a part of the burn area. After the position is adjusted, start the second drive motor 26. The second drive motor 26 drives the drive gear 27 to rotate. Under the meshing action of the drive gear 27 and the rack 25, the spiral barrel 15 will slide downward relative to the support tube 14, and the working shell 37 will be driven to move downward. When the bottom of the working shell 37 is close to the appropriate height of the patient's skin, turn off the second drive motor 26 to keep the height of the working shell 37 unchanged.

[0041] After the position is adjusted, the air suction pump 47 and the air outlet pump 45 are started to ensure that the airflow flowing inside the air suction channel 48 and the air outlet channel 41 is stable, and then the first drive motor 22 and the telescopic motor 34 are started. The first drive motor 22 drives the first rotating shaft 21 to start rotating. The push rod 23 on the surface of the first rotating shaft 21 will push the sliding column 28 on the ointment application device to slide inside the spiral turbine groove 63 under the drive of the first rotating shaft 21. During the sliding process, the air suction cylinder 19 will suck the scars that have been peeled off the patient's skin and the ointment agglomerates that have been absorbed into the air suction channel 48. The wind inside the air suction cylinder 19 can clean the peeled skin agglomerates and scars from the patient's skin surface, which will not cause pain to the patient, and can make the ointment applied again contact with the patient's burn part more fully, promote the absorption of the medicine, and speed up the patient's recovery.

[0042] The blocking blade 54 inside the air cylinder 19 can chop the agglomerates and scars sucked into the air suction channel 48 to prevent the agglomerates and scars from clogging the air cylinder 19. When large agglomerates and scars block the bottom of the air cylinder 19, the air pressure inside the air cylinder 19 cannot be released from the bottom of the air cylinder 19, and the suction force inside the air cylinder 19 is concentrated inside the chute 49. When the suction force inside the air cylinder 19 is large enough to overcome the pulling force of the spring 52, the third slider 50 will slide a certain distance inside the air cylinder 19, and the connecting rod 51 will also slide inside the air cylinder 19 under the drive of the third slider 50. At the same time, the second slider 56 connected to the connecting rod 51 also slides inside the air cylinder 19. During the sliding process, the cutting blade 53 on the surface of the second slider 56 will cut off the agglomerates and scars accumulated at the bottom of the air cylinder 19, so that the large agglomerates and scars can be broken into small pieces and can be sucked into the air cylinder 19.

[0043] During the sliding process, the telescopic motor 34 also controls the first slider 33 to move slowly downward, and the ointment inside the medicine outlet groove 38 will be squeezed out. The ointment squeezed onto the surface of the inclined surface 40 will be blown to the patient's burn part by the gas blown out of the upper air hole 42. The ointment is applied to the patient's skin surface by wind power, without contacting the patient's burn part, reducing the possibility of bacterial infection and applying it evenly. The cold air blown out of the air outlet 20 can also relieve the stinging pain caused by the drug contacting the patient's skin.

[0044] The area of ​​the present invention applied once is similar to the area of ​​the baffle 16. After the first application is completed, the position of the support tube 14 can be adjusted to continue applying until all the burn parts are applied, and the sliding groove 39 closes the medicine squeezing channel 36 to prevent the ointment from being contaminated by bacteria.

[0045] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
