Adjustable sphygmomanometer cuff with rulers

Abstract

The invention discloses an adjustable sphygmomanometer cuff with rulers, which comprises an outer cuff and a built-in inflating airbag. The long edge and the wide edge at the periphery of the cuff are respectively provided with a ruler; the built-in inflating airbag consists of 13 independent inflating airbags with the length of 250mm; and one end of each inflating airbag is communicated with a horizontal inflating channel, while the other end is a blind end. An intersection part of the inflating channel and each inflating airbag has a ball bag structure in which a small entity ball is arranged, and the small entity ball can move along the inflating channel under the action of external force to block the inflating airbag and adjust the total width of the inflating airbag. Six ball bag structures are arranged at the position of 150-250mm of each inflating airbag, and small entity balls are arranged in the ball bag structures, can move along the inflating airbag under the action of external force to adjust the length of the inflating airbag. The rulers of the cuff measure the length of the upper arm and the arm circumference of a testee, the width and length of the inflating airbags required by the cuff are calculated, and the width and length of the cuff are adjusted by moving the small balls in the inflating channel and the inflating airbags so as to meet the requirements of clinical different individuals on blood pressure measurement.

Description

technical field [0001] The invention relates to a medical device, in particular to a sphygmomanometer cuff with a ruler and adjustable length and width. Background technique [0002] The sphygmomanometer is a commonly used clinical medical device. At present, the sphygmomanometer commonly used in our country is the cuff type sphygmomanometer. The width, narrowness, length, and shortness of the sphygmomanometer cuff should match the length of the upper arm and the size of the arm circumference of the testee. If the cuff is too wide, too narrow, too long, or too short, it will affect the accuracy of blood pressure measurement. , whether it is an adult type or a child type, the blood pressure cuffs commonly used in clinical practice have fixed specifications in length and width, and cannot be adjusted from person to person, which will inevitably affect the accuracy of blood pressure measurement. The length × width of the existing adult cuff airbag is 240mm × 120mm, and the len...
