Mercury sphygmomanometers. Nws muaj ob hom: rooj thiab sawv ntsug. Tabletop mercury sphygmomanometers yog cov suab nrov thiab txhim khu kev qha; sawv sphygmomanometers yog qhov siab - kho tau thiab yog qhov feem ntau siv vim lawv cov txiaj ntsig txhim khu kev qha. Txawm li cas los xij, qhov tom kawg yog me ntsis loj dua thiab tsis tshua muaj txav, thiab ob qho tib si ua rau muaj kev pheej hmoo ntawm mercury to. Lawv lub hauv paus ntsiab lus ntsuas ntshav siab yog nyob ntawm auscultation, thiab lawv feem ntau muaj peb ntu: lub zais pa, lub cuff, thiab manometer. Cov roj hmab zais zis ntawm lub cuff yog txuas nrog lub zais pa thiab lub manometer feem, ua rau lub kaw lus kaw. Manometers tuaj nyob rau hauv ob hom: mercury kem thiab caij nplooj ntoos hlav.
Electronic sphygmomanometers. Nyob ntawm qhov chaw ntsuas, lawv tuaj yeem faib ntxiv rau sab caj npab, dab teg, ntiv tes, phau ntawv, thiab hom tsis siv neeg. Lawv qhov zoo yog qhov yooj yim ntawm kev ua haujlwm thiab kev nyeem ntawv yooj yim; tsuas yog tig ntawm qhov hloov pauv tau siv qhov ntsuas, ua rau lawv tsim nyog rau kev siv hauv tsev. Txawm li cas los xij, cov khoom siv hluav taws xob sphygmomanometers kuj muaj qhov tsis zoo ntawm qhov yuam kev loj thiab yuav tsum tau calibration nquag nrog tus qauv mercury sphygmomanometer. Nws cov qauv kev khiav hauj lwm suav nrog auscultation (tseem hu ua Korotkoff sound method) lossis oscillometric method (tseem hu ua oscillation method). Nws feem ntau muaj cov roj siab sensor, lub twj tso kua mis me me, lub tshuab hluav taws xob tswj hluav taws xob, cov software cuam tshuam, lub tshuab hluav taws xob qis qis, thiab solenoid ceev tso valve.
Lub pneumatic sphygmomanometer, tseem hu ua lub cev tsis muaj dej sphygmomanometer lossis caij nplooj ntoos hlav-loaded sphygmomanometer, siv lub twj tso kua mis los ntsuas qhov siab. Nws yog me me thiab nqa tau yooj yim, tab sis nrog kev rov siv dua, lub caij nplooj ntoos hlav lub zog tuaj yeem hloov pauv, cuam tshuam rau qhov tseeb ntawm cov txiaj ntsig. Yog li ntawd, nws yuav tsum tau calibration raws sij hawm tiv thaiv tus qauv mercury sphygmomanometer. Nws tsis tshua muaj siv kho mob tam sim no.
