Mfundo ya stethoscope

Nthawi zambiri imakhala ndi mutu wa auscultation, chubu chowongolera mawu, ndi mbedza yamakutu.Chitani (mafupipafupi) osakulitsa mawu osonkhanitsidwa.

Mfundo ya stethoscope ndi yakuti kufalikira kwa kugwedezeka pakati pa zinthu kumatenga nawo mbali mu filimu ya aluminiyamu mu stethoscope, ndipo mpweya wokha umasintha mafupipafupi ndi kutalika kwa phokoso, kufika pamtunda "womasuka" wa khutu la munthu, ndipo nthawi yomweyo. kuteteza mawu ena ndi "kumva" momveka bwino.Chifukwa chimene anthu amamva phokoso n’chakuti mawu otchedwa “phokoso” amatanthauza kugwedezeka kwa zinthu, monga mpweya umene umanjenjemera m’khutu la munthu, umene umasandulika kukhala mafunde a muubongo, ndipo anthu ‘amamva’ phokoso.Kuthamanga kwafupipafupi komwe makutu amunthu amatha kumva ndi 20-20KHZ.

Palinso muyezo wina wa kaonedwe ka mawu ka munthu, womwe ndi mphamvu ya mawu, yomwe imagwirizana ndi kutalika kwa mafunde.Kuchuluka kwa makutu amunthu ndi 0dB-140dB.Mwa kuyankhula kwina: phokoso mumtundu wa ma audio ndi lokwera kwambiri komanso lofooka kuti limveke, ndipo mawu omvera mumtundu wa voliyumu ndi ochepa kwambiri (mafunde otsika kwambiri) kapena aakulu kwambiri (mafunde apamwamba) kuti amve.

Phokoso limene anthu amamva limagwirizananso ndi chilengedwe.Khutu la munthu limateteza, ndiko kuti, maphokoso amphamvu amatha kubisa phokoso lofooka.Phokoso la mkati mwa thupi la munthu, monga kugunda kwa mtima, phokoso la m'mimba, mvula yamkuntho, ndi zina zotero, ndipo ngakhale phokoso la magazi silimamveka kwambiri chifukwa mawuwo ndi otsika kwambiri kapena phokoso ndilotsika kwambiri, kapena silimveka bwino. ndi chilengedwe chaphokoso.

Panthawi yokweza mtima, cholumikizira m'makutu cha nembanemba chimatha kumvetsera kumveka bwino, ndipo cholumikizira m'makutu chamtundu wa kapu ndichoyenera kumvetsera kuphokoso kocheperako kapena kung'ung'udza.Ma stethoscope amakono onse ndi ma stethoscope a mbali ziwiri.Pali mitundu yonse ya membrane ndi chikho pamutu wa auscultation.Kutembenuka pakati pa ziwirizi kumangofunika kuzunguliridwa ndi 180 °.Akatswiri amanena kuti madokotala ayenera kugwiritsa ntchito stethoscopes mbali ziwiri.Palinso teknoloji ina yovomerezeka yotchedwa floating membrane technology.Mutu wa membrane auscultation ukhoza kusinthidwa kukhala mutu wa khutu wamtundu wa chikho m'njira yapadera kuti mumvetsere phokoso lochepa.Phokoso la m'mapapo lachibadwa komanso losazolowereka ndi mawu okwera kwambiri, ndipo khutu lokhalo la m'mapapo ndi lomwe lingagwiritsidwe ntchito polimbikitsa mapapu.

Mitundu ya stethoscopes

Acoustic stethoscope

Acoustic stethoscope ndiye stethoscope yakale kwambiri, komanso ndi chida chodziwira matenda chomwe chimadziwika kwa anthu ambiri.Stethoscope yamtunduwu ndi chizindikiro cha dokotala, ndipo dokotala amavala pakhosi tsiku lililonse.Acoustic stethoscopes ndi omwe amagwiritsidwa ntchito kwambiri.

Electronic stethoscope

Stethoscope yamagetsi imagwiritsa ntchito ukadaulo wamagetsi kuti ikweze phokoso la thupi ndikugonjetsa phokoso lalikulu la acoustic stethoscope.Stethoscope yamagetsi imayenera kutembenuza chizindikiro chamagetsi cha phokoso kukhala phokoso la phokoso, lomwe kenako limakulitsidwa ndikukonzedwa kuti limvetsere bwino.Poyerekeza ndi ma acoustic stethoscopes, onse amatengera mfundo zakuthupi zomwezo.Stethoscope yamagetsi itha kugwiritsidwanso ntchito ndi dongosolo lothandizira pakompyuta kuti liwunikire zomwe zidachitika pamtima kapena kung'ung'udza kwamtima kosalakwa.

Kujambula kwa stethoscope

Ma stethoscope ena apakompyuta amakhala ndi mawu omveka, omwe angagwiritsidwe ntchito kulumikiza ku chipangizo chojambulira chakunja, monga laputopu kapena chojambulira cha MP3.Sungani mawu awa ndikumvera mawu ojambulidwa kale kudzera pa chomverera m'makutu cha stethoscope.Dokotala amatha kufufuza mozama komanso ngakhale kuzindikira zakutali.

Stethoscope ya fetal

M'malo mwake, kukula kwa fetal stethoscope kapena fetal scope ndi mtundu wamtundu wa stethoscope, koma imaposa mamvekedwe wamba.Stethoscope ya fetal imatha kumva mawu a mwana wosabadwayo m'mimba mwa mayi wapakati.Ndizothandiza kwambiri pakusamalira unamwino pa nthawi ya mimba.

Doppler stethoscope

Doppler stethoscope ndi chipangizo chamagetsi chomwe chimayesa mphamvu ya Doppler ya mafunde omwe amawonekera kuchokera ku ziwalo za thupi.Kusunthaku kumadziwika ngati kusintha kwafupipafupi chifukwa cha mphamvu ya Doppler, kuwonetsa mafunde.Choncho, stethoscope ya Doppler ndiyoyenera kwambiri kugwiritsira ntchito zinthu zosuntha, monga kugunda kwa mtima.
