Wrist ring of wrist-type tonometer

Abstract

A wrist cuff for a wrist-type sphygmomanometer, the wrist cuff (10) for a wrist-type sphygmomanometer comprising: a first air bag (14A) serving as a first expansion area, and a first air bag (14A) and a wrist Between, the second air bag (16A) as the second expansion area is made of a material with greater stretchability than the first air bag (14A). This wrist cuff for a wrist sphygmomanometer can reliably compress the arteries located in the wrist without being affected by the muscles, tendons and bones existing in the wrist.

Description

technical field [0001] The present invention relates to a wrist cuff for a sphygmomanometer used in a sphygmomanometer that is mounted on a living body to measure blood pressure, and more particularly to a wrist cuff for a wrist sphygmomanometer used to measure blood pressure on the wrist Meter the structure of the wristband. Background technique [0002] In recent years, more and more attention has been paid to self-management of blood pressure, and wrist-type sphygmomanometers, which can measure more conveniently than upper arms, are widely used in homes as home-use sphygmomanometers. Now refer to Figure 12 and Figure 13 The general structure of the conventional wrist-type blood pressure monitor 100 will be described. Figure 12 is an overall perspective view showing the appearance of the wrist blood pressure monitor 100, Figure 13 It is a block diagram showing the internal structure of the wrist blood pressure monitor 100 . Referring to these two drawings, a wrist b...

Problems solved by technology

However, due to the existence of the radius 2 and the flexor palmaris longus 4b, the expansion of the air bag 109 is hindered, and the radial artery 5 cannot be fully compressed, and, due to the existence of the flexor digitorum superficialis 6a and the ulnar root tendon 6b, it is hindered. The expansion of the air bag 109 cannot fully compress the ulnar artery 7

[0012] Originally, under the condition that the compression of the artery by the air bag 109 does not have any hindrance, if Figure 17 As shown in the schematic diagram of , by fully inflating the air bag 109, the prescribed wrist width W1 can be obtained. However, in the presence of the radius 2 and the flexor palmaris longus 4b, etc. Figure 18 As shown in the schematic diagram of , the expansion of the air bag 109 is hindered by the existence of the radius 2 and the flexor palmaris longus 4b, etc., so that the width W2 of the wristband is insufficient
