Title:
The blood-pressure-measurement system provided with a pressure sensor and it, or an in-vehicle system
Document Type and Number:
Japanese Patent JP6277067
Kind Code:
B2
Abstract:
Provided is a pressure sensor that can be simply connected to a three-way stopcock for use in a blood circuit and that minimizes the influence of structural change caused by connection. A pressure sensor according to the present invention: is provided with a diaphragm-type semiconductor strain gauge, an electric circuit board to which the semiconductor strain gauge is fixed, wiring that connects the semiconductor strain gauge and the electric circuit board, and a male tapered tube for transmitting pressure to the semiconductor strain gauge; is configured from a case for holding the electric circuit board therein; and is characterized in that the male tapered tube has a double tube structure and a recessed end of the male tapered tube is covered by a protruding elastic body thin film.
