摘要： An extracorporeal circuit includes a tube holder holding a pump tube and line tubes. The tube holder has first and second tube holding portions holding the pump tube in a loop shape and holding the line tubes and a fixing plate coupling the first tube holding portion and the second tube holding portion to each other. The fixing plate is configured such that a line-tube-side end thereof is inclined to a pump tube side from a second tube holding portion side toward a first tube holding portion side.

摘要： A guide extension catheter including a distal shaft and a proximal shaft, wherein: a main body of the distal shaft is placed on a support base of a three-point bending test jig where a distance between fulcrums is 15 mm; an indenter that approaches the support base at a speed of 10 mm/min in a middle between the fulcrums is pressed against the main body from a lateral side to deform the main body until kinking occurs; and at that time, a maximum load value acting on the main body is 0.1 to 0.6 N. A distal end tip that is more flexible than the main body is provided to the distal shaft. The distal end tip has a length dimension of 2.5 mm or greater, and includes a marker part mixed with a powder made of a radiopaque material.

摘要： In a vacuum heat insulating double walled container 1, adsorbent blocks 30 are formed in block, and each of the adsorbent blocks 30 disposed on the peripheral surface of a sample storage container 25 is placed on a partition plate 27. Moreover, an inner container 10 is hang in an outer container 3 using a connecting tube 20 formed of a thin material having an uneven outer peripheral surface, and a heat insulating tube 40 is disposed on the inner surface of the connecting tube 20. Further, as to a workpiece carrier 50 as a fixing device, a carrier guide 52 is in close contact with the heat insulating tube 40, and a plate-like portion 54 and a workpiece storage portion 51 are disposed in a non-contact state with respect to the sample storage container 25. As a result, it is possible to suppress the amount of heat transferred from the inner container 10 to the outer container 3, and vibration and impact is less likely to applied to a sample in the workpiece storage portion 51 even if an external force such as impact is applied to the vacuum heat insulating double walled container 1.

摘要： A pre-filled syringe includes a tubular container, a front end gasket, a rear end gasket, an intermediate gasket, a medicine, a liquid medicine, and a plunger. The tubular container has a barrel and a nozzle portion. The barrel has an inner peripheral surface and a protruding inner side surface. A groove is formed in an outer peripheral surface of the intermediate gasket. The front end gasket has a rear-end pressure-contact portion. The nozzle portion has an accommodation portion. The accommodation portion has a bottom wall, a peripheral wall, and a supporting portion. The rear-end pressure-contact portion is in pressure contact with the inner peripheral surface of the barrel in an abutment state in which the liquid medicine is introduced in the front chamber and the front end portion of the front end gasket is in abutment with the supporting portion.

摘要： An outer needle assembly 10 comprises an outer needle 48 wherethrough an inner needle 16 passes, and a passage forming member 50 connected to the outer needle 48 and including a valve body 64 inside such that a first internal space 78 on a distal side of the valve body 64 is longer than a second internal space 79 on a proximal side thereof. A ventilation path 80 for discharging air to an outside communicates with the first internal space 78 near the valve body 64. The first internal space 78 comprises: a puncture part 56 formed in a puncturing portion of the outer needle 48; a tapered part 57 formed on the proximal side of the puncture part 56 with an inner diameter increasing toward the proximal side; and a small-diameter part 89 formed on the proximal side of the tapered part 57 with an inner diameter smaller than or equal to that of a proximal end of the tapered part 57.

摘要： There is provided a technique for detecting leakage in extracorporeal blood circulation while suppressing increased cost in a dialysis device. A dialysis device includes an artery-side blood circuit, a dialyzer, and a vein-side blood circuit. The dialysis device detects an abnormality based on a difference between theoretical value and measured value of a blood concentration in the vein-side blood circuit. The theoretical value of the blood concentration in the vein-side blood circuit is specified based on blood concentration and blood flow rate in the artery-side blood circuit and a water removal rate in the dialyzer.
