Patent number: 8858532Abstract: 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.Type: GrantFiled: April 20, 2010Date of Patent: October 14, 2014Assignee: JMS Co., Ltd.Inventors: Masahiro Tsunematsu, Yuma Hayashi, Takehiko Yuki

Patent number: 8186384Abstract: A flow control apparatus 1 including a tubular outside member 4, a tubular inside member 10 placed in the outside member 4, and a valve member 20 is used. The inside member 10 includes a through-hole 14 passing through a side wall in a thickness direction and a contact portion 11 that is in contact with the outside member 4, which are arranged in that order in a direction from one opening 16 to the other opening 17. The valve member 20 is placed in the opening 17 of the inside member 10. The valve member 20 passes only a fluid supplied at a set pressure or higher in a direction from the one opening 16 to the other opening 17. The outside member 4 is formed so as to form a gap communicating with the through hole 14 between the outside member 4 and the contact portion 11 due to elastic deformation caused by an external force. The gap forms a flow path of a fluid in combination with the through-hole 14.Type: GrantFiled: January 15, 2007Date of Patent: May 29, 2012Assignee: JMS Co., Ltd.Inventors: Ryoji Fujii, Takehiko Yuki

Patent number: 8105312Abstract: 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.Type: GrantFiled: February 7, 2005Date of Patent: January 31, 2012Assignee: JMS Co., Ltd.Inventors: Raita Uematsu, Takehiko Yuki, Naotsugu Ito, Ryoji Fujii, Tadashi Okiyama
