[0002] Before hematopoietic stem cell transplantation, patients often need to undergo skin pretreatment at multiple sites (puncture site, donor site, etc.) while lying in bed. Current procedures have many drawbacks: the limited bed position makes it difficult to accurately cover the target area with manual cleaning and disinfection, and improper control of the force can easily damage the fragile skin after transplantation; traditional tools have poor adaptability to different positions (lying flat, lying on the side), resulting in uneven application of medication; direct contact with low-temperature medication can easily cause patient discomfort, and cleaning residual medication in the tubing after surgery is cumbersome and increases the risk of cross-infection.
[0003] Chinese patent document CN119909260B discloses a skin pretreatment device for hematopoietic stem cell transplantation care, comprising a support base, an annular track plate, a rubber ring, a regional cleaning mechanism, a plate-type protection mechanism, a pressure-regulating closure mechanism, and a multi-tube blood collection mechanism. The annular track plate is located on the upper wall of the support base, the rubber ring is located on the inner wall of the annular track plate, the regional cleaning mechanism is located on the annular track plate, the plate-type protection mechanism is located at the end of the regional cleaning mechanism away from the annular track plate, and the pressure-regulating closure mechanism is located on the side wall of the plate-type protection mechanism. This invention provides a skin pretreatment device for hematopoietic stem cell transplantation care that can support and protect the patient's puncture site, and can provide negative pressure protection to the puncture site, reducing the number of times the puncture site comes into contact with outside air and lowering the probability of infection at the puncture site.
[0004] The aforementioned skin pretreatment device for hematopoietic stem cell transplantation can provide basic protection and pretreatment for the patient's puncture site, but it has limitations in terms of operational precision, patient skin compatibility, and device maintenance efficiency. Its angle adjustment lacks fine control, making it difficult to flexibly match the body position of different patients and the skin pretreatment needs of multiple areas. The cushioning effect of the parts in contact with the skin is limited, which can easily cause additional stimulation to the fragile skin tissue after hematopoietic stem cell transplantation. Furthermore, the disassembly and assembly process of the core functional components is complicated, which is not conducive to rapid disinfection and replacement. Summary of the Invention

The medication is then transported to the hollow tube 13 and atomized and sprayed out through the atomizing nozzle 14. After the nursing care is completed, the device is moved aside, and the shut-off valve on the suction tube 37 is closed and the shut-off valve on the clean fluid tube 38 is opened, so that the water in the clean water tank 41 can be drained. On the one hand, the medication is atomized and sprayed onto the patient's nursing position, realizing the automatic heating, spraying and wiping process of the medication. On the other hand, it is convenient to drain the water in the clean water tank 41 after the nursing care is completed, and the medication in the pipeline can be flowed and cleaned, which improves the automation effect of the device and enhances its practicality.
[0029] Working principle: The hydraulic rod 19 drives the square bar 5 upward, then moves the device to the side of the bed. Simultaneously, the electric push rod 30 drives the connecting plate 6 to move to the left, while the motor 165 drives the worm gear 164 to rotate. The worm gear 164 meshes with and drives the worm wheel 163 to rotate, which in turn drives the rod body 162 and the connecting plate 6 to rotate, thus adjusting the left and right angle of the connecting plate 6. The motor 172 also drives the shaft 173 to rotate, which in turn drives the gear 174 to rotate. The gear 174 meshes with and drives the column 7 to rotate. Then, the hydraulic rod 19 drives the square bar 5 and the mounting plate 10 downward, and the silicone pad 11 automatically adheres to the patient's skin. When the silicone pad 11 contacts the patient's skin, it automatically... The connecting rod 91 and the sliding plate 92 move upward, while the sliding plate 92 is buffered by the spring 93 and the damper 94, controlling the heating of the heating plate 22 and the starting of the motor 25. The motor 25 drives the rotation of the stirring rod 23 and the stirring arm 24, while the stirring arm 24 stirs the medicine in the medicine tank 2. Then, the water pump 36 is started, and the medicine in the medicine tank 2 is drawn through the suction pipe 37. Then, the medicine is added to the rotary joint 28 through the metal pipe 39 and the elastic pipe 40. Then, the medicine is transported to the hollow tube 13 and atomized and sprayed out through the atomizing nozzle 14. If the treatment is completed, the device is moved aside, and the shut-off valve on the suction pipe 37 is closed and the shut-off valve on the clean liquid pipe 38 is opened, so that the water in the clean water tank 41 can be drained.
