A catheter device according to one aspect of the present invention includes: a tube to be inserted into a body; a light emitting unit, which is provided on a distal end side of the tube, and includes an infrared light emitting element configured to emit infrared light for verifying a position of the tube; a power supply line configured to supply electric power to the infrared light emitting element; and a conduction detection unit including a visible light emitting element configured to notify a conduction state between the power supply line and the infrared light emitting element by means of visible light. With the catheter device, operation of the light emitting unit can be visually checked before inserting the tube.

Catheter device

A waterproof pressure sensor includes a pressure detection element, a cavity package configured to be provided with a recess in which the pressure detection element is mounted and an edge provided around the recess, a frame configured to be attached to the edge of the cavity package and has a surface more smoothed than the edge and an opening, a contact prevention member configured to be attached to the frame, and a pressure introducing hole having a diameter smaller than a diameter of the opening at a position overlapping the opening, and a gel agent configured to be provided in the recess and the opening, in which the gel agent is provided to be separated from an edge of the pressure introducing hole on the frame side.

Waterproof pressure sensor, and manufacturing method and sensor conveyance body for manufacturing waterproof pressure

In a pressure detection device which is provided in an intake pressure measurement apparatus, a detection space surrounded by an outer wall portion is formed in a housing, and an inner wall portion is formed integrally in the detection space such that both end portions are connected to the outer wall portion. The inner wall portion has a cylindrical shape, and a sensor storage portion is formed between the inner wall portion and the outer wall portion. In the sensor storage portion, a pressure sensor is disposed in a region with the least influence of thermal stress at a position closer to the inner wall portion than the outer wall portion.
