Indlela yokukhetha i-sphygmomanometer ukujonga uxinzelelo lwegazi ekhaya?

Ukuchaneka:

I-Sphygmomanometers kwimarike inokwahlulwa ngokohlulo lwekholamu yemercury kunye nohlobo lwe-elektroniki.Uhlobo lwekholomu ye-mercury lunesakhiwo esilula kunye nokuzinza okulungileyo.Iincwadi zezifundo zonyango zicebisa ukuba iziphumo zalo mlinganiselo ziya kuphumelela.Nangona kunjalo, ikwanazo nezingeloncedo ezifana nomthamo omkhulu, ongaphathekiyo, imekyuri ivuza ngokulula, ayinakusebenza yodwa, kwaye ifuna uqeqesho lokuyisebenzisa.Ngokuqhelekileyo isetyenziswa kumaziko ezonyango.Ngenxa yongcoliseko lwemekyuri, i-mercury sphygmomanometers ziye zavalwa kwezinye ukuba zisetyenziswe.Ngokuqhelekileyo isetyenziswa kumaziko ezonyango.Ngenxa yongcoliseko lwemekyuri, ii-mercury sphygmomanometers ziye zavalwa kumazwe athile aseYurophu anjenge France.

I-electronic sphygmomanometer ilula kwaye ikhawuleza ukusebenza, ukufundwa okucacileyo, kwaye inokusebenza ngokuzimeleyo ngaphandle kokungcola.Nangona kunjalo, abantu abaninzi bacinga ukuba ixabiso elilinganiswe nge-elektroniki liya kuba liphantsi kwaye ligubungele imeko.Enyanisweni, ukuba isetyenziswe ngokuchanekileyo, ukuchaneka kwe-electronic sphygmomanometers kuphantse kufana ne-mercury, kwaye ichaneke ngakumbi kuba akukho mpazamo yomntu.Izibhedlele ezininzi zisebenzisa i-electronic sphygmomanometers kakhulu, kwaye i-mercury sphygmomanometers isetyenziswa kuphela xa iziphumo zingathandabuzeki.uqinisekiso.

Enyanisweni, nayiphi na i-sphygmomanometer iya kulinganiswa xa ishiya i-factory, kwaye ukuchaneka kuya kuncipha ngokuqinisekileyo emva kokuyisebenzisa ixesha elide.Ukuphindaphinda kokusetyenziswa kwe-sphygmomanometers yasekhaya kuncinci kakhulu kunezibhedlele, ngoko ke ukuchaneka akuyi kuhla ngokukhawuleza.

Ukusebenza:

I-Mercury sphygmomanometers ineemfuno eziphezulu kumlinganiso, ngokukhethekileyo abasebenzi bezonyango, abafuna ukugxila ekuphulaphuleni izandi ze-pulse, kwaye bajwayele ukulinganisa kunye nokurekhoda ukuphambuka, okungafanelekanga kumakhaya amaninzi.

Ii-sphygmomanometers ze-elektroniki eziqhelekileyo ziquka uhlobo lwengalo ephezulu kunye nohlobo lwesandla.Uhlobo lwengalo ephezulu kunye nodidi lwekholamu yemercury zombini zilinganisa uxinzelelo lwegazi lwengalo engaphezulu.Iziphumo zezi zimbini zisondele kakhulu, kwaye kulula ukuyisebenzisa.Ikwayi-sphygmomanometer yosapho ecetyiswayo kwizikhokelo zoxinzelelo lwegazi kwilizwe lam.Nangona kunjalo, kufuneka kuqatshelwe ukuba impazamo enkulu inokubangelwa xa ibhetri iphantsi.

Imveliso ehambelanayo neMonitor yeBp401 echanekileyo ephezulu
