According to the study, after the platelets have been thawed, they need to be kept shaking when they are waited to be transfused to the patient. The full name of temperature controlled shakers (22°C) is platelet thermostatic oscillation preservation chamber. The temperature range is 22±2℃.Special equipment mainly used for platelet preservation, suitable for blood centers, clinical transfusion departments, blood banks, and blood product production units. The Temperature controlled shakers (22°C) provide continuous horizontal oscillation with an amplitude of 50 mm and a frequency of 60 cycles/min, which solve the problem of platelet safe storage. The platelet storage bag is valid for 120 hours (5 days) in the shaker.
