Ikhanda elikhulu le-stethoscope liyisici esihlukile sale stethoscope yezilwane. Iklanyelwe ngokukhethekile ukunikeza ukudluliswa komsindo okuthuthukisiwe kanye nokukhulisa ukuze kutholwe kangcono imisindo yenhliziyo yesilwane namaphaphu. Ikhanda lingashintshwa kalula phakathi kwezinto zethusi ne-aluminium, okuvumela odokotela bezilwane ukuba bakhethe okufanelana kangcono nezintandokazi zabo kanye nezidingo zabo. Amathiphu ethusi anikeza ukuzwela kwe-acoustic okuhle kakhulu futhi aziwa ngekhono lawo lokukhiqiza ikhwalithi yomsindo efudumele necebile. Ifaneleka ngokukhethekile ukuthwebula imisindo yefrikhwensi futhi ilungele ukukhulisa izilwane ezinkulu ezinezimbobo zesifuba ezijulile. Ngakolunye uhlangothi, ikhanda le-aluminium lilula kakhulu, okwenza kube lula ukulisebenzisa isikhathi eside. Iphinde futhi inikeze ukudluliswa komsindo okuhle futhi ikhethwa ekuthuthukiseni izilwane ezincane noma lezo ezinezakhiwo zomzimba ezintekenteke kakhulu.
Ukuqinisekisa ukuqina nokuphila isikhathi eside, i-stethoscope yezilwane ifakwe i-diaphragm yensimbi engagqwali. Lawa ma-diaphragm awakwazi ukugqwala nokugqwala, ahlinzeka ngokusebenza okuthembekile ngisho nasezindaweni zodokotela wezilwane eziyinselele. I-diaphragm ingahlanzwa kalula futhi ibulawe amagciwane, igcine izindinganiso ezinhle zokuhlanzeka kodokotela bezilwane nezilwane. Sekukonke, i-stethoscope yezilwane iyithuluzi lokuxilonga elisebenza ngezindlela eziningi nelibalulekile kodokotela bezilwane. Ikhanda layo elikhulu le-stethoscope kanye nezinto ezishintshashintshayo zethusi noma i-aluminium kuyenza ifanele izilwane ezihlukahlukene, kusukela emfuyweni emikhulu kuya ezilwaneni ezincane ezingabangane. I-diaphragm yensimbi engagqwali inomthelela ekuqineni kwayo nasekugcinweni kalula. Ihlanganiswe nalezi zici, le stethoscope yenza odokotela bezilwane bakwazi ukuhlola ngokunembile impilo yesilwane futhi banikeze ukunakekelwa kwezokwelapha okufanele.
