Abstract

Provided is a pulse wave measuring apparatus preventing breakage of a pressure sensing surface in the non-measurement stage. The pulse wave measuring apparatus includes: a housing and a pressure sensing section, wherein an opening is formed at the bottom surface of the housing, the pressure sensing section is mounted inside of the housing, the pressure sensing section moves freely upwardly and downwardly through the opening between a measuring position at which a pressure sensing surface is pressed to a human body to measure a pulse wave and a waiting position at which the pressure sensing section 20 is accommodated inside of the housing to be on standby and the housing has a slide cover protecting the pressure sensing surface in a state where the pressure sensing section is located at the waiting position.

Claims

1. A pulse wave measuring apparatus comprising:

a housing having a protective cover, a case body having an opening, and a base body; and

a pressure sensing section having a pressure sensing surface, mounted inside of the housing and moving freely upwardly and downwardly between a measuring position at which the pressure sensing surface is pressed to a human body to measure a pulse wave and a waiting position at which the pressure sensing section is accommodated inside of the housing,

the protective cover protecting the pressure sensing section in a state where the pressure sensing section is located at the waiting position, wherein

the case body accommodates the pressure sensing section and the base body is adapted to fix the case body to a human body,

the base body has an insertion hole to accommodate the pressure sensing section moving between the waiting position and the measuring position in a freely, upwardly and downwardly movable manner,

the case body is mounted to the base body so that the case body can slide along the base body between a first position at which the pressure sensing surface faces the insertion hole and a second position at which the pressure sensing surface does not face the insertion hole, and

the protective cover faces the pressure sensing surface in a state where the case body is located at the second position.

2. The pulse wave measuring apparatus according to claim 1, wherein the pressure sensing section is located at the waiting position and a distance between the protective cover and the pressure sensing surface in a state where the case body is located at the second position is more than a moving distance of the pressure sensing section moving between the waiting position and the measuring position.
