  • Patent number: 10881848
    Abstract: A connector is connectable to a medical device that includes a female connector portion. The connector includes: a main body member including: a cylinder portion that is insertable into the female connector portion, and a lock portion configured to, upon insertion of the cylinder portion into the female connector portion, pass over part of the medical device and then move in a predetermined locking direction to lock the medical device; and a lock member that is movable with respect to the main body member. When the main body member is in a state in which the lock portion locks the medical device, the lock member is moveable to a lock position at which the lock member limits movement of the lock portion in a predetermined unlocking direction.

  • Patent number: 10799693
    Abstract: A connector of the present invention includes a housing and a valve, wherein the housing has a flow path and a pipe connecting port, and the valve is formed of an elastic material and is adapted to block the pipe connecting port. The valve has a substantially columnar deformable portion. The deformable portion has a top surface exposed from the pipe connecting port, a bottom surface opposite to the top surface, and a slit that reaches extends from the top surface to the bottom surface. When the top surface is pressed by the pipe, the deformable portion of the valve will be displaced toward the flow path while elastically deforming, so that inner surfaces that define the slit will face the flow path, and the top surface will form an opening that communicates with the flow path.
