Description

Technical Field

[0001] The invention relates to the technical field of skin cleaning, in particular to a skin cleaning device for blood disease hematopoietic stem cell transplantation. Background Art

[0002] Hematopoietic stem cell transplantation is a procedure that uses high-dose radiotherapy and chemotherapy to pre-treat the recipient to remove tumors or abnormal cells in the recipient's body. The recipient is then transplanted with autologous or allogeneic hematopoietic stem cells to rebuild their normal hematopoietic and immune systems. Transplant patients may develop skin complications. The skin is the body's protective layer. Once the skin of a granulocytic patient is damaged, it is prone to infection and loss of water and electrolytes. Therefore, the patient needs to clean and care for the skin every day. Daily skin care must keep the skin intact and dry. At this time, a skin cleaner needs to be used for cleaning.

[0003] Publication No. 202220141737.5 discloses a skin cleaner for blood disease hematopoietic stem cell transplantation care, comprising a mounting plate, a rotating shaft rotatably connected to the mounting plate, and a rotating plate fixedly connected to one end of the rotating shaft. A first mounting shaft is fixedly connected to one side of the rotating plate, a second mounting shaft is fixedly connected to the other side of the rotating plate, a first cleaning roller is rotatably sleeved on the first mounting shaft, a second cleaning roller is rotatably sleeved on the second mounting shaft, a first nut is threadedly installed on one end of the first mounting shaft, a second nut is threadedly installed on one end of the second mounting shaft, a hand-tightening bolt is threadedly penetrated through the mounting plate, and one end of the hand-tightening bolt contacts the rotating plate. Instead of repeatedly adhering cleaning liquid to the medical sponge to clean the transplanted part of the patient, it is beneficial to the work intensity of medical staff and improves the cleaning efficiency.

[0004] However, when using the existing skin cleaner for hematopoietic stem cell transplantation for blood diseases, it is not convenient to evenly spray the cleaning liquid on the first cleaning roller. At the same time, during the cleaning process, it is necessary to spray and add the cleaning liquid multiple times, which is very inconvenient and affects the cleaning efficiency and effect.

When the sliding plate 202 moves in the direction away from the rotating disk 703, the cleaning liquid in the fixed cover 201 can be squeezed. At the same time, the first one-way valve 205 is closed and the second one-way valve 213 is opened. At this time, the cleaning liquid in the fixed cover 201 enters the annular cavity 19 through the liquid supply pipe 210 and the first hose 211, and enters the first cleaning roller 16 through the liquid outlet 20. This reciprocating process can automatically and evenly add cleaning liquid to the first cleaning roller 16 during cleaning, making it more convenient and ensuring the cleaning efficiency and effect. After the first cleaning is completed, the electromagnet 1002 is powered off. At this time, the moving ring 901 and the connecting key 802 can be moved and reset under the action of the second spring 903. Then, the rotating plate 14 is rotated to interchange the positions of the second cleaning roller 18 and the first cleaning roller 16, and the limiting mechanism 5 is used to limit the position. Then, the second cleaning roller 18 is attached to the skin of the patient's part to be cleaned, and the second cleaning roller 18 is repeatedly rolled for the second cleaning to dry the patient's skin. At the same time, the second connecting shaft 805 is aligned with the second rotating rod 702, and then the electromagnet 1002 is energized. At this time, the connecting key 802 can be inserted into the third key slot 806, so that the power of the first rotating rod 17 and the second rotating rod 702 is connected. When the second cleaning roller 18 rotates repeatedly, the first rotating rod 17 and the second connecting shaft 805 are driven to rotate synchronously, and the second rotating rod 702 and the rotating disk 703 are driven to rotate through the connecting key 802. At the same time, the first solenoid valve is closed. 207 and the second solenoid valve 212, open the fourth solenoid valve 402 and the third solenoid valve 404. At this time, when the sliding plate 202 reciprocates in the fixed cover 201, the external air can enter the fixed cover 201 through the air supply pipe 401 and the liquid extraction pipe 204, and then enter the fixed pipe 301 through the liquid supply pipe 210, the second hose 403 and the U-shaped pipe 303, and blow on the surface of the patient's clean skin through the air blowing pipe 302, so that the skin drying efficiency is higher and the effect is better; When the positions of the first cleaning roller 16 and the second cleaning roller 18 need to be interchanged, the moving block 503 is pulled to make the clamping block 504 move downward and withdraw from the clamping slot 502. At the same time, the third spring 603 is compressed. Then, the rotating plate 14 is rotated along the rotating shaft 13. At the same time, when the rotating shaft 13 rotates, the fixing ring 501 is driven to rotate synchronously. Moreover, the clamping block 504 can abut against the side wall of the fixing ring 501 and slide on the side wall under the action of the third spring 603. When the block 504 is aligned with the other slot 502, the block 504 can be inserted into the other slot 502 under the action of the third spring 603, so that the fixing ring 501 and the rotating shaft 13 can be limited, which is more stable and reliable, and ensures that the rotating plate 14 is flipped 180 degrees, that is, the position of the second cleaning roller 18 and the first cleaning roller 16 are interchanged, so that the interchange of the first cleaning roller 16 and the second cleaning roller 18 is more convenient and quick, which can improve the cleaning efficiency.
