Abstract: An observation device configured to observe a sample stored in a multistage container including a plurality of spaces divided by a plurality of partition walls which are parallel. The observation device includes: a light source configured to generate light; a phase contrast microscope configured to irradiate the sample with light from the light source and to make executable observing a phase difference due to interference of light returned from the sample; and a reflection mirror configured to reflect light passed through the sample again toward the sample. The reflection mirror is inclined with respect to the plurality of partition walls of the multistage container.

Abstract: Provided is a tube set which is capable of easily determining whether a holder has been mounted when the holder is mounted on a housing. The tube set, which is provided in a tube pump that feeds a liquid, includes a pump tube and a holder. The holder has a flexible flat plate and includes first and second engagement portions located away from each other in a first direction. The first and second engagement portions are configured to be fitted into first and second engagement grooves formed in the housing, respectively, when the holder is pushed into the housing in a state of being bent in a thickness direction. The holder is elastically restored to be attached to the housing when the engagement portions are fitted into the respective engagement grooves. The holder has a flexural modulus of 500 MPa or more and 3500 MPa or less.

Abstract: 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.

Abstract: 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.

Abstract: 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.
