Patients who are bedridden are for a long-time prone to develop bedsores, especially in the hip and sacral areas and limbs, which causes eczema, ulcers, infection and other complications, resulting in pain and more medical costs. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a kind of anti-bedsore turning pad, and has obtained the national utility model patent (ZL 2021 2 3004923.9), which is suitable for various long-term bedridden patients. The anti-bedsore turning pad includes the center axis of the turning pad, and ventilation pad 1 and ventilation pad 2 designed on the left and right of turning pad center axis. Under the ventilation pad 1 and the ventilation pad 2, the air pad 1 and the air pad 2 are respectively designed. There is a bedspread connected with ventilation pad 1 and ventilation pad 2 on the inflatable pad 1 and the inflatable pad 2. Through the design of inflatable pad 1 and inflatable pad 2, the left and right of the anti-bedsore turning pad can be lowered or raised independently, which is convenient for the patient's body to tilt and turn over, and can significantly reduce the number of nursing staff and the burden of nursing staff when turning over. In addition, it is convenient to replace the force site at any time and reduce the occurrence of pressure ulcers caused by long-term pressure on the force site. Through the design of ventilation cushion 1 and ventilation cushion 2, the internal gas flow of the turning pad can be made, and the ventilation between the patient and the turning pad can be kept dry, so as to reduce the occurrence of eczema, ulcers or infection and other complications, and ultimately reduce the occurrence of bedsores. In addition, through the design of the most superficial limb pad, the patient's limb can be appropriately elevated or massaged, which increases the comfort of the patient. The anti-bedsore turning pad is simple and effective, and can be widely used in long-term bedridden patients.

Blood purification is one of the commonly used techniques for the rescue of critically ill patients, which is used for acute and chronic kidney injury caused by various causes and renal replacement therapy (RRT) for a variety of critical diseases. Its main working principle is to drain the human blood into a variety of dialyzers through the artificial tube, exchange substances through a variety of ways, and remove harmful substances and some metabolites from patients' body. Then the purified blood is transfused back to the body, so as to maintain the patient's internal environment relatively stable. At present, there are different models of hemodialysis machines in clinical practice, but they are bulky and unable to move, and the method of heat dissipation is single, which cannot meet the needs of hemodialysis treatment in transport patients. Therefore, the medical staff of the Second Affiliated Hospital of Zunyi Medical University designed and developed a hemodialysis machine, which is suitable for patients who demand hemodialysis treatment during transport, and obtained the National Invention Patent of China (ZL 2020 1 0864737.3). The hemodialysis machine comprises a main body of the hemodialysis machine and a mobile vehicle. The main body of the hemodialysis machine is placed in the bottom of the mobile vehicle, and a protective cylinder with fixed airbags is designed around the main body of the hemodialysis machine. The fixed airbag is connected to the air storage tank through the pipeline, the air storage tank is connected to the Venturi tube through the control valve, and the throat of the Venturi tube is connected to the disinfection tank and cooling water tank. The outlet end of the Venturi tube is connected with the cooling pipe inside the main part of the hemodialysis machine and the sprinkler head placed on the top of the main body. By adding a mobile vehicle and designing an airbag and protective cylinder, the hemodialysis machine can be applied to the hemodialysis treatment during the transportation of patients. By designing the heat dissipation pipe, the main body of the hemodialysis machine can be cooled, the temperature of the hemodialysis machine can be reduced, and the hemodialysis machine can still work when the fan is damaged. By designing the sprinkler head, it is convenient to automatically disinfect the main screen and control keys of the hemodialysis machine, reduce the risk of cross infection of medical staff in the operation, and increase the safety and practicability of the hemodialysis machine. The hemodialysis machine is convenient, safe and efficient, which can be widely used in the hemodialysis treatment during transported patient, and is worthy of clinical promotion.
