Abstract:
1. A blood pressure measuring device comprising: a cuff having an inflatable/deflatable fluid bag; a main-unit casing in which an inflation/deflation mechanism inflating/deflating said fluid bag is disposed; a flexible connection tube connecting said fluid bag and said inflation/deflation mechanism and having a stopper portion preventing a cuff-side tube portion of said connection tube from being drawn into said main-unit casing; and a retraction mechanism capable of drawing in said connection tube that is drawn out from said main-unit casing, into a connection tube housing provided in said main-unit casing, wherein in a state where said connection tube is housed to as much extent as possible in said connection tube housing by said retraction mechanism, at least a part of said connection tube is located on the outside of said main-unit casing, said main-unit casing has an opening for drawing out said connection tube, said stopper portion abuts on a periphery of said opening and thereby prevents said connection tube from being further drawn in into said main-unit casing, said cuff-side tube portion of said connection tube has one end connected to said fluid bag, said connection tube includes a main-unit-casing-side tube portion having one end connected to said inflation/deflation mechanism and a connector connecting the other end of said cuff-side tube portion and the other end of said main-unit-casing-side tube portion, and said stopper portion is formed of said connector.
