摘要
A hub assembly for a pen injection device prevents a patient from seeing a needle of a hub assembly during an injection. A hub is connected to the pen injection device. A needle is received by the hub. A compressible member is connected to the hub and is compressible between a first position that entirely covers said needle and a second position that exposes the needle for an injection.
