Abstract: A method for implementing multiple PDNs between an indoor unit and an outdoor unit may include: allocating at least two first VLAN interfaces to a first physical network interface; establishing packet data network (PDN) data channels which are in one-to-one correspondence with the first VLAN interfaces, wherein the PDN data channels are configured for data interaction with a base station; acquiring address allocation requests corresponding to the PDN data channels from the IDU; and allocating first IP addresses corresponding to the PDN data channels to the IDU according to the address allocation requests, such that data messages from the IDU are routed to the corresponding PDN data channels according to the first IP addresses.

Abstract: An infusion cassette of an infusion set is provided with a flow channel, and includes a rigid assembly, elastic membranes and a locking mechanism. The rigid assembly includes a plurality of components stacked onto one another, at least one of the components is provided with a groove, and the elastic membranes are each arranged between two adjacent components to cover the groove in a sealing manner; and the locking mechanism includes a mounting frame and a liquid stop plug fixedly arranged on the mounting frame, and configured to press the elastic membranes to close the flow channel, the locking mechanism closes or opens the flow channel by the liquid stop plug. The mounting frame is movably connected to the rigid assembly, such that the locking mechanism is switched between a closed state in which the flow channel is closed and an open state in which the flow channel is opened.
