The present application provides a trypsin detection film, a preparation method therefor, application thereof and a trypsin detection kit, which relates to the technical field of trypsin detection. The preparation method for the trypsin detection film comprises the following steps: providing a polymer film substrate; immersing the polymer film substrate in a dye solution to attach a dye to the polymer film substrate, so as to obtain a trypsin detection film.

A medical visualisation device including an instrument elevator having a guide surface for engagement with an instrument protruding through a tip part instrument channel and a X-ray transparent housing. The instrument elevator is radiopaque and pivotable around a pivot axis to adjust a guide angle between the guide surface and a longitudinal axis. The pivot axis being substantially perpendicular to the longitudinal axis and a viewing direction. A control wire being coupled to the instrument elevator to transfer a force exerted on the control wire to the instrument elevator to adjust the guide angle.

A medical visualisation system including a first medical visualisation device having a first device colour identifier, a second medical visualisation device having a second device colour identifier, a third medical visualisation device having a third device colour identifier, and a monitor device, the first device colour identifier being a first colour, the second device colour identifier being a second colour, and the third device colour identifier being a third colour. The first colour has a first hue angle, the second colour has a second hue angle, and the third colour has a third hue angle, wherein the first hue angle and the second hue angle differ by more than 40 degrees, the second hue angle and the third hue angle differ by more than 40 degrees, and the third hue angle and the first hue angle differ by more than 40 degrees.

A method for image-capturing of an internal organ by a miniature imaging device, comprising: generating a light at a first light intensity on to a subject area of an internal organ and capturing an image of the subject area by a miniature imaging device configured under default exposure parameter values; computing a second light intensity and optimized exposure parameter values based on brightness of the captured image, an orientation, a position, and a motion of the miniature imaging device; and generating a light at the second light intensity on to the subject area and recapturing the image of the subject area by the miniature imaging device configured under the optimized exposure parameter values. The second light intensity and optimized exposure parameter values are derived by an ex vivo processing unit in wireless data communication with the miniature imaging device.

Provided are a diagnostic imaging device, a diagnostic imaging method, a diagnostic imaging program and a learned model, which can improve the diagnostic accuracy for esophagus cancer in esophagogastroduodenoscopy. This diagnostic imaging device comprises: an endoscopic image acquisition unit for acquiring an endoscopic moving image showing the esophagus of a person being tested; an estimation unit for estimating the location of esophagus cancer that is present in the acquired endoscopic moving image, using a convolutional neural network that has learned from esophagus cancer images as training data, the esophagus cancer images having been obtained from esophaguses affected by esophagus cancer; and a display control unit that superimposes on the endoscopic moving image an estimated location of the esophagus cancer and a certainty factor serving as an index for the probability that esophagus cancer is present at that location.

A positive pressure ventilation (PPV) appliance module includes an adapter that couples to a port on an NIV mask and an appliance for performing a respiratory care procedure. The adapter is configured to form a PPV seal with the port of the PPV mask and also form a PPV seal with the appliance. The PPV appliance module allows clinicians to perform procedures through the NIV mask without disrupting the therapeutic pressure.
