Therefore, there is a requirement for shock absorption performance for the storage container of the ex vivo blood. However, the current storage containers for ex vivo blood either have an insignificant shock absorption effect or are relatively complex in structure and not practical. Therefore, it is necessary to develop a storage container with a simple structure and good shock absorption effect to transport and store platelets (ex vivo blood) to minimize the exogenous stimulation of platelets.
