Abstract
A medical tube-connector device that enables easy connection and disconnection without allowing channel ends to be touched by fingers. The first connector body includes a channel that can communicate with a tube, and is removably attached to the first connector body. The second connector body includes a channel and a concave part into which the protective cap can be inserted. A displaceable guide cap is attached to the second connector body. In a preparatory state, the concave part into which the protective cap can be inserted is open and the end of the channel is sealed. In the connected state, the end of the channel is open. The protective cap is maintained in the concave part so as to be detached from the first connector body and at the same time the channels of the first and second connector bodies communicate.

A medical tube-connector device having two connectors for connecting tubes, the two connectors being connectable to or disconnectable from each other, comprising:
- a first connector, including:
- a first connector body having a channel extending through its inside and being connectable to a tube at one end of the channel;
- and
- a protective cap capable of being attached to or detached from the first connector body for covering and sealing the other end of the channel in a state in which the protective cap has been attached to the first connector body;
- and
- a second connector, including:
- a second connector body having a channel extending through its inside and a concave part into which the protective cap of the first connector can be inserted, the second connector body being connectable to a tube at one end of the channel;
- and
- a guide cap capable of being displaced with respect to the second connector body and being provided with a cover portion for covering and sealing the other end of the channel in the second connector body,
- wherein the second connector body and the guide cap can be brought into a preparatory state or a connected state by their relative displacement, in the preparatory state the concave part of the second connector body being open and the other end of the channel being sealed by the cover portion, and in the connected state the other end of the channel being open, and
- by inserting the first connector with the protective cap attached into the concave part in the preparatory state and then bringing the second connector body and the guide cap into the connected state, the protective cap is moved while being retained in the concave part so as to be detached from the first connector body and at the same time the first connector body and the second connector body are connected, thus allowing their channels to communicate.
A connector that is one of two connectors being connectable to or disconnectable from each other for connecting tubes so as to form a medical tube-connector device, comprising:
- a casing with an annular shape, having, at its periphery:
- at least one inflow/outflow port for liquids, which can be connected to a tube;
- and
- an insertion opening into which the other connector can be inserted together with a protective cap for sealing an opening of the other connector;
- a rotor being formed of a substantially cylindrical body mounted rotatably inside the casing, the rotor having:
- a fluid channel extending through an inside of the cylindrical body and forming inflow/outflow ports on a peripheral surface of the cylindrical body;
- and
- at least one cap receiving recess being formed on the peripheral surface of the cylindrical body and being capable of receiving the protective cap for sealing the opening of the other connector,
- wherein the rotor and the casing can be brought into a preparatory state or a connected state depending on their relative rotational positions, in the preparatory state the insertion opening of the casing opposing the cap receiving recess in the rotor and thus the inflow/outflow ports in the rotor being sealed by the casing, and in the connected state the insertion opening of the casing opposing one of the inflow/outflow ports of the rotor and the inflow/outflow port of the casing and the other inflow/outflow port of the rotor communicating with each other, and
- by inserting the other connector in the preparatory state into the cap receiving recess through the insertion opening and then bringing the rotor and the casing into the connected state, the protective cap for sealing the other connector is retained in the cap receiving recess so as to be detached from the connector and at the same time the channels of the other connector and the rotor communicate.
A connector that is one of two connectors being connectable to or disconnectable from each other for connecting tubes so as to form a medical tube-connector device, the connector comprising:
- a connector body, which is attached to an end of a tube and has a through hole that communicates with the tube;
- and
- a protective cap, which is attached to the connector body and seals an opening of the connector body,
- wherein the protective cap is detached from or attached to the connector body by being slid in a direction substantially orthogonal to an axial direction of the through hole.
A connector that is one of two connectors being connectable to or disconnectable from each other for connecting tubes so as to form a medical tube-connector device, comprising:
- a connector body having a channel extending through its inside and a concave part into which a protective cap for sealing an opening of the other connector can be inserted, the connector body being connectable to a tube at one of the channel;
- and
- a guide cap capable of being displaced with respect to the connector body and being provided with a cover portion for covering and sealing the other end of the channel of the connector body,
- wherein the connector body and the guide cap can be brought into a preparatory state or a connected state by their relative displacement, in the preparatory state the concave part of the connector body being open and the other end of the channel being sealed by the cover portion and in the connected state the other end of the channel being open, and in the connected state, the guide cap can be detached from the connector body in a state where the other connector and the connector body are maintained in a coupled state.
