Sphygmomanometer Phau Ntawv Qhia

Qee tus kws kho mob siv digital rau kev tshuaj ntsuam tab sis siv Sphygmomanometer Phau Ntawv Qhia kom siv tau cov ntawv nyeem hauv qee qhov xwm txheej. Phau ntawv sphygmomanometers muaj xws li aneroid (dial) thiab mercury (kem) li. Kev khiav hauj lwm cov khoom siv aneroid thiab mercury no yuav luag ib yam, tshwj tsis yog tias cov khoom siv aneroid yuav tsum tau ua raws sij hawm.A Sphygmomanometer Manual yog ib yam khoom uas ntsuas ntshav siab. Nws yog tsim los ntawm cov roj hmab inflatable cuff, uas yog qhwv ib ncig ntawm caj npab. Lub ntsuas ntsuas qhia lub cuff' lub siab. Ib lub teeb inflates lub cuff thiab lub valve tso siab. Lub stethoscope yog siv los mloog cov suab nrov ntawm cov hlab ntsha.

Raws li lub plawv dhia, cov ntshav yuam los ntawm cov hlab ntsha ua rau muaj kev nce siab, hu ua systolic siab, ua raws li kev txo qis hauv siab raws li lub plawv' s ventricles npaj rau lwm qhov kev sib tw. Qhov siab qis no hu ua diastolic siab.

Cov Mechanisms ntawm Phau Ntawv Qhia Sphygmomanometer

Tam sim no, phau ntawv sphygmomanometer muaj peb ntu. Thiab cov no suav nrog lub tshuab ua pa, lub ntsuas ntsuas, thiab cov txheej txheem rau kev nce nqi. Thiab yog tias koj muaj peev xwm paub txog kev kuaj koj cov ntshav siab, koj paub tseeb tias txhua yam ntawm cov txheej txheem no.

Txawm li cas los xij, ntawm no yog lub luag haujlwm tseem ceeb ntawm cov ntu no yog tias koj xav dhia mus rau qhov nam:

Inflatable Cuff

Thaum koj raug kuaj xyuas koj cov ntshav siab, thawj yam uas tus kws saib xyuas neeg mob lossis tus kws kho mob yuav ua rau koj yog cia koj txhais tes ncab ntawm nws. Raws li lub caj npab twg, nws yeej nyob ntawm. Thiab thaum koj tuaj yeem ncab koj txhais caj npab tawm, cov ntaub ntawv zoo li cov ntaub ntev ntev yuav muab tso rau ntawm koj txhais caj npab npog koj lub mem tes qhov twg nws ua suab nrov tshaj plaws.

Cov khoom no yog pom tau tias yog inflatable cuff. Nws yog ib feem stretchable tab sis nws yog lig adjustable nyob ntawm seb qhov loj ntawm koj txhais caj npab. Thiab muab tso rau ntawm koj txhais caj npab tsis yog ib qho yooj yim npog-dhau. Tus kws saib xyuas neeg mob lossis kws kho mob yuav xyuas kom meej tias lub ntsej muag lub ntsej muag yuav npog tag nrho cov chaw ntxiv.

Chav ntsuas ntsuas

Qhov thib ob ntawm sphygmomanometer yog qhov ntsuas ntsuas. Thaj, muaj ob chav kawm ntawm phau ntawv sphygmomanometers. Thiab cov chav kawm no feem ntau sib txawv nyob ntawm seb hom kev ntsuas tshwj xeeb. Cov no yog mercury manometer thiab aneroid gauge.

Hauv ntau lub tsev kho mob thiab cov tsev kho mob, feem ntau hom ntsuas ntsuas uas ib txwm tuaj hauv sphygmomanometer yog mercury manometer. Thiab feem ntau tsis yog, nws yog hu ua tus qauv kub.

Raws li nws tshwm sim, hom no tsis xav tau recalibration. Tsis zoo li aneroid gauge units, mercury manometers muab cov txiaj ntsig raug dua.

Ntawm qhov tod tes, aneroid gauge units yog qhov nyuaj heev los siv. Tab sis lawv muaj kev nyab xeeb dua ntawm nws cov ntaub ntawv vim nws tsis muaj mercury hauv nws. Txawm li cas los xij, calibration tseem ceeb heev hauv chav ntsuas no. Qhov no yog vim li cas nws feem ntau hu ua mechanical sphygmomanometer.

Tab sis thaum lawv nyuaj heev
