A medical connector structure configured in such a manner that a first member body which constitutes a connector base and a second member body which consists of a different material from the first member body are formed by two-color injection molding. The first member body is a tube body which has a connector-side section having a structure connected to a mating section, and also has a tube-side section having on the surface thereof projections and recesses. The second member body is a tube body which allows a raw material to be filled into the portion in which the projections and recesses are provided and into which a raw material is filled so as to allow a tube body to be inserted. The tube-side section and the tube body are adhered together.

Medical connector structure

A flow control apparatusincluding a tubular outside member, a tubular inside memberplaced in the outside member, and a valve memberis used. The inside memberincludes a through-holepassing through a side wall in a thickness direction and a contact portionthat is in contact with the outside member, which are arranged in that order in a direction from one openingto the other opening. The valve memberis placed in the openingof the inside member. The valve memberpasses only a fluid supplied at a set pressure or higher in a direction from the one openingto the other opening. The outside memberis formed so as to form a gap communicating with the through holebetween the outside memberand the contact portiondue to elastic deformation caused by an external force. The gap forms a flow path of a fluid in combination with the through-hole

The present invention aims at offering: a syringe connectable to a port in a fixed manner as well as capable of demonstrating high operational performance even in the case of direct connection where a connector is not used; a connector used for the syringe; and a syringe able to attach the connector thereto. For the attainment of the above objectives, the medical syringe of the present invention is a medical syringe including a cyrindrical connection supporting member which enhances the holding force of a luer part inserted into a port when the medical syringe is connected to the port. The connection supporting member is set by sliding along the luer or a syringe body in a state of being movable between a first position near a tip of the luer and a second position away from the tip of the luer. The medical syringe is characterized in that, when the connection supporting member is moved to the second position, the tip of the luer part is exposed.

A three-way stopcock that can be opened/closed in the same manner as conventional operation methods and can reduce stagnated portions of fluid in a fluid flow passage. Out of branch openings, a first branch opening and a second branch opening are arranged on a straight line, and a third branch opening is directed perpendicularly to the line connecting the first and second branch openings. Provided at a flow passage switch portion are a first flow-passage opening and a second flow-passage opening that are arranged on a straight line and a third flow-passage opening that is directed perpendicularly to the line connecting the first and second bran openings.

Three-way stopcock, and liquid transfusion circuit or blood transfusion circuit either using the three-way stopcock

A container cap or a liquid communication adapter attachable to a container mouth having a conventional rubber-like stopper. A container cap includes at least one disk-like valve provided with an insertion hole in a central portion thereof, and a cover for restraining the valve by covering at least an upper periphery of the valve. A lower periphery on a back surface of the valve is supported by a seating portion of a container mouth or a seating portion of a joint that is supported by the container mouth, and the container cap has an anchor for anchoring an insertion member to the cap by using a peripheral edge forming a fitting hole in the cover, while inserting the insertion member into the insertion hole.
