Ukusuka ekuMameleni ukubetha kwentliziyo ukuya kuxilongo kwangethuba: Indima yeStethoscope kuQeqesho lweKlinikhi

Imbali kunye neNguqulelo yeStethoscope

Kwaqanjwa ngaphakathi 1816 nge French ugqirha URené Laënnec, i stethoscope yi isixhobo sonyango iqhele uku mamela izandi eziveliswa ngaphakathi emzimbeni, ngokuyintloko entliziyweni okanye emiphungeni. Iqale yenziwa ityhubhu yeplanga ye-monaural, i-stethoscope iye yatshintsha kakhulu, yaba sisixhobo se-binaural esineetyhubhu zerabha eziguquguqukayo kunye neqhekeza lesifuba esaziyo namhlanje. Ukuveliswa kwayo kuphawule inqanaba elibalulekileyo kwezamayeza, livumela oogqirha ukuba bamamele izandi zomzimba wangaphakathi ngaphandle kokudibana ngokuthe ngqo ngokomzimba, ukuphucula ucoceko, kunye nokubonelela ngoxilongo oluchanekileyo.

Ukusebenza kunye neentlobo zeStethoscopes

I-stethoscope isebenza kwi ukuhanjiswa kwesandi kwiqhekeza lesifuba, ngeetyhubhu ezizele ngumoya, ezindlebeni zomphulaphuli. Iqhekeza lesifuba lidla ngokuba namacala amabini anokubekwa kwisigulana ukubona izandi: a isaci (idiski yeplastiki) okanye a bell (indebe engenanto). I-diaphragm ifanelekile ukuba ibanjwe Isantya esiphezulu ivakala njengezandi zomphefumlo oqhelekileyo, ngelixa intsimbi isebenza ngakumbi frequency ephantsi ivakala ngathi iyambombozela intliziyo. Kukwakho nee-electronic acoustic stethoscopes ezinokurekhoda kunye nokuhambisa izandi njengeefayile zedijithali.

Ukusetyenziswa kweKlinikhi yeStethoscope

I-stethoscope yi isixhobo sokuxilonga esisisiseko ekusebenzeni kweklinikhi, esetyenziselwa ukufumanisa izinto ezingaqhelekanga kwiinkqubo zokuphefumla kunye nenhliziyo, kunye neenkqubo zokugaya kunye ne-venous. Ukongeza, kunjalo kubalulekile kumlinganiselo woxinzelelo lwegazi lweklinikhi, kudityaniswe nekhafu yoxinzelelo lwegazi. Ukulula kwayo kunye nokuchaneka kwayo kuyenza ibe sisixhobo esingenakuthathelwa indawo kwindawo yezonyango.

Ukubaluleka kunye neMpembelelo kumayeza

I-stethoscope ingaphezulu nje kwesixhobo sonyango; yi uphawu lomsebenzi wokhathalelo lwempilo. Ikhono layo lokubonelela ngolwazi oluxabisekileyo kubasebenzi bezempilo, ukuphucula iziphumo zesigulane kunye nomgangatho wokuxilongwa, kwenza kube yinto ebalulekileyo kumayeza anamhlanje. Ukuziphendukela kwayo okuqhubekayo kunye nokulungelelaniswa kweemfuno zeklinikhi zangoku kuqinisekisa ukubaluleka kwayo okungapheliyo.
