Abstract: A device (100) for measuring the amount of water in a subject's body includes a main body part (110) formed in a linear shape and an insertion part (120) extending in a curved shape from one end of the main body part (100). The insertion part (120) includes a tip side insertion part (120-2) having a tip surface (122) to which a sensor unit (121) is fixed and a base end side insertion part (120-1), wherein the sensor unit (121) is brought into contact with a body surface of a subject through a slide mechanism. A protective member (651) liquid-tightly covers the slide mechanism between the tip side insertion part (120-2) and a base end side insertion part (120-1). The protective member (651) smoothly connects the outer peripheral surface of the tip side insertion part (120-2) and the outer peripheral surface of the base end side insertion part (120-1).

Abstract: A system visually distinguishes diseased tissue from healthy tissue after a treatment is administered to a patient to provide different concentrations of a fluorescent marking substance between the diseased tissue and the healthy tissue. A light source illuminates the tissue with excitation light. A detector detects light returning from the tissue, and a controller characterizes the returning light according to a measured property indicative of the different concentrations. A light projector projects light having a predetermined cue in response to the characterization of the returning light.

Abstract: A surgical fixing tool for vascular anastomosis inhibits an operation site on a surface of a living body such as a heart from moving along a height direction of the surface of the living body. The fixing tool has a position adjusting unit disposed in a support unit 10 that adjusts a relative position between the support unit and the fixed living body local site. A displacement position detection unit detects a displacement position of a local site. Based on a detected displacement, the position adjusting unit changes and adjusts a relative position between the support unit and the fixed local site.

Abstract: A manufacturing method for medical equipment involves electron beam irradiating a titanium or titanium alloy substrate surface that has at least been machined, whereby platelet adhesion of the surface to be contacted by blood is reduced. The manufacturing method for medical equipment can also use a specific pre-processing method and an electron beam irradiation method to reduce the platelet adhesion of the surface which is to be contacted with blood, to suppress the formation of minute depressions (craters) in the surface, which can occur due to the irradiation by an electron beam.

Each prong has a distal end with a claw and is bendable so that its respective claw expands over a lip and enters the groove of the outlet port. A lock nut is movable between a retracted position and a locking position. In the retracted position, a soft interconnect is obtained. In the locking position, the claws are prevented from escaping over the lip and a hard interconnect is obtained.
