The pressure detection device comprises a housing and a pressure detection assembly. the housing has a piezometric cavity and a mounting cavity, the piezometric cavity has an air inlet for communicating with a piezometric interface of the sheath tube and a vent hole for communicating with the outside, and a switch is arranged at the vent hole; and the pressure detection assembly is arranged in the mounting cavity and includes a gauge pressure sensor, a voltage regulating circuit, an operational amplifier circuit and a conversion circuit; the gauge pressure sensor, the voltage regulating circuit and the operational amplifier circuit are electrically connected with the conversion circuit, and the gauge pressure sensor is used for converting a pressure signal in the piezometric cavity into a voltage signal.

A sealing device for endoscope intubation and an endoscope are provided in the present disclosure, which includes: a main body part, wherein the main body part has an axis, and is used for connecting to the catheter, at least a portion of the main body part is configured to be capable of being inserted into the tracheal intubation, and there is a gap between the main body part and the inner tube wall of the tracheal intubation; a sealing part, which is annularly arranged on the main body part, wherein the sealing part is configured to seal the gap; and a friction part, which is arranged on the main body part, wherein at least portion of the friction part is configured to abut against the inner wall of the tracheal intubation.

An imaging system includes an image sensor and a reception device. The image sensor outputs a reset signal and a pixel signal to a signal line. The reception device includes a reception circuit, an abnormality determination circuit, a correction circuit, and a signal generation circuit. The reception circuit receives the reset signal and the pixel signal. The abnormality determination circuit determines whether a value of the reset signal is abnormal. The correction circuit corrects the value of the reset signal when the abnormality determination circuit determines that the value of the reset signal is abnormal. The signal generation circuit generates a difference signal indicating a difference between the reset signal having the value corrected by the correction circuit and the pixel signal.

An endoscopic flexible tube including a flexible-tube base containing metal as a constituent material, and a cover layer covering an outer periphery of the flexible-tube base, wherein the cover layer includes a polyester having a naphthalene structure and a component having an action of inhibiting a reaction of an active species such as a radical, an endoscopic medical apparatus including the endoscopic flexible tube, and a covering material for the endoscopic flexible-tube base.

An information processing device includes a processor including one or more hardware components. The processor is configured to obtain a classification result that a kind of an insertion shape of an endoscope insertion portion inserted into a subject is classified as one of a plurality of predetermined kinds, and output the classification result.

An image processing device includes a processor including hardware, the processor being configured to execute: estimating an operation state of a medical apparatus in a lumen of a subject based on information sequentially input from the medical apparatus, the medical apparatus including an imaging device, and an insertion portion inserted into the lumen, and the information including at least an intraluminal image obtained by the imaging device capturing an image inside the lumen; and performing processing corresponding to the operation state of the medical apparatus in the lumen based on an estimation result.
