An apparatus is operable to process a medical instrument by passing a detergent and a disinfectant through a plurality of channels defined by the medical instrument. The apparatus includes a detection system, a set of instrument profiles, and a control system. The detection system is configured to collect information regarding the channels of the medical instrument. The control system is configured to pass a detergent and a disinfectant through the channels of the medical instrument based at least in part on a selected instrument profile selected from the set of instrument profiles. The selected instrument profile is selected based at least in part on the information collected by the detection system.

A medical instrument processor includes an enclosure, a liquid distribution system, and a disinfectant concentration measuring subsystem. The enclosure is configured to hold a medical instrument. The liquid distribution system is configured to deliver a disinfection solution to a medical instrument within the enclosure. The liquid distribution system has a liquid outlet. The disinfectant concentration measuring subsystem includes a first mixing chamber in fluid communication with the liquid outlet, a pump that is configured to simultaneously pump the disinfection solution and the reagent solution into the first mixing chamber, and a concentration analysis assembly that is operable to determine a concentration of disinfectant in a sample solution that is output from the first mixing chamber. The reservoir is in fluid communication with the first mixing chamber.

A pressure monitoring device is provided for use with a tool such as a medical endoscope. The device includes a housing which is fluidically coupled with an internal volume of the endoscope. A pump is used to change the pressure inside the device housing and endoscope, thereby establishing a pressure differential from the ambient environment. During an endoscopy procedure, the pressure inside the device housing is monitored, and a change in pressure exceeding a predefined limit causes an alarm signal indicating a leak has occurred in the endoscope. The device housing may be directly mounted to the endoscope, located remotely and connected with a coupling tube, or integrated with an accessory device connected to the endoscope. The pump may be integrated internally to the device housing, or it may be a separate external pump which is connected to the housing. The pressure differential may be positive or negative relative to ambient.

An endoscope system includes a light source apparatus for emitting narrow band light of green and violet in field sequential lighting, for endoscopic imaging. An image sensor has multiple pixels arranged on an imaging surface, for imaging an object in a body cavity illuminated with the narrow band light, to output a pixel signal. The multiple pixels include first and second pixels. The first pixel has a lower spectral sensitivity than the second pixel. A gain corrector is supplied with the pixel signal by the image sensor, for performing gain correction of multiplying the pixel signal of the first pixel by a gain value, so as to compensate for a difference in the spectral sensitivity of the first pixel from the second pixel. Also, a noise reduction device performs noise reduction of the pixel signal after the gain correction according to the gain value.

A stereo comparator configured for use with a stereo endoscope for adjusting and aligning an optical assembly of the stereo endoscope, for example, in connection with the repair of the endoscope. The comparator includes a housing containing a plurality of optical components, namely, a first deflecting component, a second deflecting component, a third deflecting component and a beam splitter. The optical components are arranged so that the first deflecting component deflects a first beam from a right image channel of a stereo endoscope to the beam splitter, the second deflecting component deflects a second beam from a left image channel of the stereo endoscope to the third deflecting component, the third deflecting component deflects the second beam to the beam splitter and the beam splitter combines the first beam with the second beam to form a first combined beam that extends along an optical axis of the stereo endoscope.

A capsule medical device guidance system includes: a capsule medical device including a permanent magnet and configured to be introduced into a subject; a magnetic field generator configured to generate a magnetic field to be applied to the capsule medical device; an operation input device configured to input operation information; and a processor including hardware.

The present disclosure relates to an endoscopy system. The endoscope system includes: a first light source unit which is installed on a substrate; a second light source unit which is installed on the substrate and which emits light when the first light source unit does not emit light; an optical unit through which the light of the first light source unit or the second light source unit passes; a light guide unit which induces the light which passed through the optical unit to the inside of a target object; an image sensing unit which senses the light reflected and reached from the target object and which converts the sensed light into an image signal; and an image signal processing unit which processes the image signal to display on a display unit.

A fluorescent type of green light source of a semiconductor in a light source apparatus for an endoscope includes a blue excitation light source device and green emitting phosphor. The blue excitation light source device emits blue excitation light. The green emitting phosphor is excited by the blue excitation light, and emits green fluorescence. A dichroic filter in a dichroic mirror cuts off the blue excitation light from an emission spectrum of mixed light of the blue excitation light and green fluorescence from the fluorescent type of green light source. Thus, illumination light with the emission spectrum of a target can be stably supplied without influence of the blue excitation light to a light amount of blue light from a blue light source of a semiconductor.
