PROBLEM TO BE SOLVED: To provide an attitude retainer for blood component separation apparatuses that retains an attitude of a blood component separation apparatus capable of improving a collection rate of leukocyte components.SOLUTION: An attitude retainer 16 includes a first attitude retaining member 17 and a second attitude retaining member 18 that are mounted on a blood component separation apparatus 1 to clamp the blood component separation apparatus 1 from both front/rear sides. When the first and second attitude retaining members 17 and 18 are mounted on the blood component separation apparatus 1, the first and second attitude retaining members 17 and 18 are formed with: a first accumulation-part storage unit 25 for storing a volume adjusting mechanism 3, and a first accumulation part 4; a connecting-part storage unit 29a for storing a connecting part 10 formed of a tube with flexibility; a third accumulation-part storage unit 27 for storing a third accumulation part 6; a connecting-part storage unit 29b for storing a connecting part 11 with flexibility; and a second accumulation-part storage unit 26 for storing a second accumulation part 5, in this order, respectively.
Abstract:
A rotator 2 is supported rotatably on a base 1, and a roller 7 is supported rotatably at the outer periphery of the rotator 2. A pressing member 4 has a circular arc pressing surface 4a and can be located selectively in a retracted position where a groove-shaped space 8 is formed between the pressing surface and the rotator and in a proximity position where the pressing surface is closer to the rotator. When the pressing member is in the retracted position, a pump tube can be inserted in the groove-shaped space. The pressing member is moved to the proximity position with the pump tube being held, and then the rotator is rotated, so that the pump tube is pressure-driven by the roller. The injection device with a simple structure easily can extract almost the entire semi-solidified nutritional supplement from a nutritional supplement container and inject it into a patient.

PROBLEM TO BE SOLVED: To provide a configuration surely exhausting air in priming and preventing generation of a stasis area even during blood circulation.SOLUTION: A hollow-fiber membrane type oxygenator includes: a housing 1 that forms a gas exchange part 3 in which a bundle of a plurality of hollow-fiber membranes 12 are disposed; gas ports 9 and 10 that circulate gas including oxygen through lumens of the hollow-fiber membranes; a blood flow path 4 that traverses the hollow fiber bundle in the gas exchange part and circulates the blood; and a tubular blood introduction port 5 and blood discharge port 6 that are provided in the housing in both end sides of the blood flow path. The blood discharge port is so configured that a base-end-side opening part that is a connecting portion to the housing, includes an uppermost peripheral edge of a flow path cross section of the blood flow path, the direction of a tube axis B of the distal end part of the blood discharge port is upward inclined in a vertical plane that includes a flow path central axis A of the blood flow path, and an angle θ formed by the direction of a tube axis of the blood discharge port heading for the downstream side with respect to the direction of the flow path central axis heading for the downstream side is set within 0

PROBLEM TO BE SOLVED: To provide a new differentiation accelerator accelerating the differentiation of mesenchymal stem cells with excellent safety, and a method for accelerating the differentiation.SOLUTION: As a differentiation accelerator for accelerating the differentiation of mesenchymal stem cells, an ultrasonically treated blood humoral component is used. Concretely, by culturing the mesenchymal stem cells with a medium including the blood humoral component, the differentiation of the mesenchymal stem cells can be accelerated. As the blood humoral component, e.g. those derived from peripheral blood and derived from umbilical cord blood can be cited. By the method for accelerating the differentiation, from the mesenchymal stem cells, the differentiation to e.g. osteoblast cells, cartilage cells or the like can be accelerated.

PROBLEM TO BE SOLVED: To continuously perform training of a desired part of an oral cavity.SOLUTION: A training instrument 1 for an oral cavity function to be used by being inserted into an oral cavity includes: a base part 10 which has a plate shape extending in an insertion direction into the oral cavity and is inserted into the oral cavity; and an expansion part 20 disposed on the oral cavity inner side of the base part 10. On the upper surface and the lower surface of the base part 10, an upper side groove 11b and a lower side groove 12b are disposed. The upper side groove 11b and the lower side groove 12b are shifted in the longitudinal direction of the base part 10.

PROBLEM TO BE SOLVED: To provide a jack fixing structure for a portable device capable of having a waterproof function while using a general-purpose jack. SOLUTION: A DC jack 80 is configured such that a cylindrical protrusion 82 accommodating a connector connected with a plug is formed on one face of a rectangular parallelepiped main body 81. A fixing member 90 is formed into a substantially U-shape by two parallel leg parts 90a and 90a which are made into wedges with tapered ends and a connection 90b which connects the proximal ends of the two leg parts. An O-ring 91 is attached on the outer periphery of the protrusion of the DC jack. The protrusion is made to face a mounting hole 71 so that a jack-side groove 83 and a case-side groove 73 are arranged in a partially overlapping manner. The leg parts of the fixing member are inserted into spaces S defined by the jack-side groove 83 and the case-side groove 73. The wedges formed on the leg parts cause the DC jack to slide with respect to a lower casing 20, and the protrusion is inserted in the mounting hole, while the O-ring is deformed to be in close contact with a portion of the lower casing around the mounting hole.

Abstract:
PROBLEM TO BE SOLVED: To prevent a pair of connectors for connecting two channels from being improperly connected to a connector with an inappropriate structure.SOLUTION: A first connector 1 includes: a cap 3; a tubular pedestal 6 integrally provided with the cap and projecting to a distal end side; a tubular projection 8 projecting from the center at the distal end of the pedestal; and an engagement nail 9 projecting outward from part of the peripheral edge at the distal end of the pedestal. A second connector 2 includes: a tube coupling part 4; an inner tube 11 integrally formed with the tube coupling part, projecting to the distal end side and insertable into the tubular projection of the first connector; an outer tube 12 combined with the proximal end side of the inner tube to form an annular recess 13 which can be fitted with the tubular projection between the outer tube and the outer peripheral surface of the inner tube; and an engagement wall 5 coupled to the outer tube, extending toward the distal end side in the tube axial direction and projecting further than the distal end of the outer tube. The first connector and the second connector are connected to each other by fitting the tubular projection into the annular recess and engaging the engagement nail with the engagement wall.

PROBLEM TO BE SOLVED: To provide a connector in which a contact area to a PEG catheter is large, a strong connection is formed, and the operation of connection and release is simple.SOLUTION: The connector includes: a tubular male connector member 4 in which a second tube 2 is installed in a rear end, and a distal end is inserted in the connection end of a first tube; a lock auxiliary member 5 in which a side edge projection 11 is formed along both side edges of a slit 10 in an axial direction, and that is installed at an outside of the first tube; and a lock member 6 that has a body part 6a in which an inner circumferential surface groove 18 of an axial direction is formed, and connection engaging parts 19 and 20 that releasably engage with a male connector member and a lock auxiliary member, and that is installed in an outside of the lock auxiliary member. At least one of the outer edge of the side edge projection and the inner circumferential edge of the inner circumferential surface groove inclines so that a space between the outer edges or a width of the inner circumferential edge expands toward a distal side from the connection end of the first tube. The lock auxiliary member is transformed through the touching of the inner circumferential surface groove and the side edge projection along with the fitting of the lock member and the lock auxiliary member, and the interval of a slit narrows.
