Abstract: To prevent a user from accidentally pricking the user with a hollow needle when separating blood components using a syringe and a connection device. A blood component separation apparatus has three syringes and a connection device. The connection device is attached to one syringe and is inserted into other syringes. The connection device has a first member to which a base end of a hollow needle is joined and a second member which is connected to the first member in such a manner as to be able to move relative to the first member. The second member is moved back and forth between a first position where a tip of the hollow needle is accommodated and a second position where the tip of the hollow needle is exposed. The second member has elastic portions which are elastically deformed in the movement from the first position to the second position. The elastically deformed elastic portions elastically energize the second member at the second position to the first position side with respect to the first member.

Abstract: There is provided a composite porous membrane comprising a porous membrane comprised of an organic polymeric compound, and a supporting porous membrane adjacent to the porous membrane, characterized in that the organic polymeric compound constituting the porous membrane penetrates in at least part of a surface adjacent to porous membrane of the supporting porous membrane, the porous membrane having specified opening ratio, average pore diameter, standard deviation of pore diameter, ratio of through pore, average membrane thickness, standard deviation of membrane thickness and internal structure, and that the supporting porous membrane has communicating pores of 0.5 D ?m or greater average pore diameter. Further, there are provided a blood filtration membrane comprising the composite porous membrane; a leukocyte removing filter unit comprising the composite porous membrane as a second filter; and, utilizing the composite porous membrane, a cell culturing diaphragm and method of cell culturing.

Abstract: A subcutaneous infusion device includes an indwelling member which has a base portion and a cannula reaching an inside of a body of a user when the base portion is fixed to a surface of the body of the user, and a coupling member which is attached to the indwelling member in a detachable/attachable manner. The coupling member includes a main body portion, a needle provided at the main body portion and communicated with the cannula when the coupling member is attached to the indwelling member, a lid portion provided turnably with respect to the main body portion, an engagement portion locking the lid portion to the main body portion, and an elastic member biased when the lid portion is locked to the main body portion and capable of biasing the lid portion in a turning direction when the locking is being released.

Abstract: [Problems]To provide a membrane material that realizes effective and efficient separation of a target substance of micron size, being easy to handle and that can be worked into various forms; a blood filtration membrane and a leukocyte removing filter unit that realizes a substantial reduction of filter material volume while retaining high capability of removing leukocytes, thereby reducing the loss of hemocyte suspension; and a cell culturing diaphragm suitable for co-culturing and a relevant method of cell culturing.

Abstract: A method for acylating a hexakis (arylmethyl) hexaazaisowurtzitane (WB6) by reductively removing the arylmethyl groups in the presence of an acylating agent, characterized by contacting a WB6 (a) with a heterogeneous system reduction catalyst (b) in the presence of an acylating agent (c) and a reducing agent (d) in a solvent (e) for the WB6 (a) to reductively remove the arylmethyl groups from the WB6 (a) and acylate the same, and by preventing the WB6 (a) and the catalyst (b) from being contacted with each other when at least either of the acylating agent (c) and the reducing agent (d) is not present. In this method, the decomposition of the WB6 skeleton, which readily occurs in the beginning of the acylation of the WB6 as a starting material, can be highly effectively inhibited. This method can hence stably produce a tetraacylhexaazaisowurtzitane derivative in a high yield and is industrially advantageous.
