Wrist strap, electronic sphygmomanometer and vital sign monitor

Abstract

The invention provides a wrist strap, an electronic sphygmomanometer and a vital sign monitor, the wrist strap comprises a first air chamber and a second air chamber which are sealed into a double-layer air bag, a connecting layer and a vent hole are arranged between the first air chamber and the second air chamber, the connecting layer is arranged in the middle of the inner sides of the first airchamber and the second air chamber, and the vent hole is formed in the middle of the connecting layer; in the inflation process, air circulates between the first air chamber and the second air chamber through the vent holes to enable the double-layer air bag to be expanded, and the effective width of the wrist strap is maintained through the connecting layer in the expansion process. The effective width of the air bag can be wider, and the accuracy of blood pressure detection can be improved conveniently; on the basis, under the condition that the wrist strap with the same width is adopted, the expansion bulging height of the wrist strap is higher, the wrist strap can only expand and bulge in the single direction, the gas amount of a gas inflation source can be more effectively utilized,more gas can be inflated, and the wrist strap is thinner, smaller and simple and efficient in assembly mode.

Description

technical field [0001] The invention relates to a wristband, in particular to a wristband suitable for blood pressure detection, and further to an electronic blood pressure monitor and a vital sign monitor including the wristband. Background technique [0002] The wristbands of wrist-type electronic sphygmomanometers in the market are usually composed of a cloth cover and an air bag built into the cloth cover. In wearable sphygmomanometers, portable sphygmomanometers or watch-type electronic sphygmomanometers, the wristband is set on the bottom or side of the case. However, since the size of the wristband itself where the airbag is located is limited, its width cannot be made too wide. During the blood pressure detection process, since the airbag needs to be inflated, it will expand during the inflation process and further affect its effective width. , so that the accuracy of the detection results will be affected accordingly; on the other hand, since the wearable sphygmoman...

[0002] The wristbands of wrist-type electronic sphygmomanometers in the market are usually composed of a cloth cover and an air bag built into the cloth cover. In wearable sphygmomanometers, portable sphygmomanometers or watch-type electronic sphygmomanometers, the wristband is set on the bottom or side of the case. However, since the size of the wristband itself where the airbag is located is limited, its width cannot be made too wide. During the blood pressure detection process, since the airbag needs to be inflated, it will expand during the inflation process and further affect its effective width. , so that the accuracy of the detection results will be affected accordingly; on the other hand, since the wearable sphygmomanometer, portable sphygmomanometer or watch-type electronic sphygmomanometer is directly worn on the user's wrist, then the wristband airbag's narrow The requirements for lightness and lightness will be relatively high, and it cannot be made too wide and / or too thick. The electronic sphygmomanometers in the prior art obviously cannot meet this demand
