Umgomo we-stethoscope

Ngokuvamile iqukethe ikhanda le-auscultation, ithubhu yokuqondisa umsindo, ne-ear hook. Enza (imvamisa) ukukhulisa okungaqondile komugqa komsindo oqoqiwe.

Isimiso se-stethoscope siwukuthi ukudlidliza phakathi kwezinto kubamba iqhaza efilimini ye-aluminium ku-stethoscope, futhi umoya wodwa ushintsha imvamisa nobude begagasi bomsindo, ufinyelele uhla lwendlebe yomuntu “ekhululekile,” futhi ngesikhathi esifanayo. ukuvikela eminye imisindo “nokuzwa” kucace kakhudlwana. Isizathu esenza abantu bezwe umsindo ukuthi lokho okubizwa ngokuthi “umsindo” kubhekisela ekudlidlizeni okufanayo kwezinto, njengomoya onyakazisa ulwelwesi lwe-tympanic endlebeni yomuntu, oluguqulwa lube imisinga yobuchopho, futhi abantu “bangezwa” umsindo. Imvamisa yokudlidliza izindlebe zomuntu ezingazizwa ingu-20-20KHZ.

Kunenye indinganiso yombono womuntu womsindo, okuwumthamo, ohlobene nobude beza. Ibanga lokuqina lokuzwa komuntu okujwayelekile lingu-0dB-140dB. Ngamanye amazwi: umsindo osebangeni lomsindo mkhulu kakhulu futhi awunamandla ukuthi ungawuzwa, futhi umsindo osebangeni levolumu mncane kakhulu (amaza amaza aphansi) noma mkhulu kakhulu (amaza amaza aphezulu) ukuthi ungawuzwa.

Umsindo abantu abangawuzwa nawo uhlobene nemvelo. Indlebe yomuntu inomphumela wokuvikela, okungukuthi, imisindo enamandla ingavala imisindo ebuthakathaka. Umsindo ongaphakathi emzimbeni womuntu, njengokushaya kwenhliziyo, umsindo wamathumbu, imisindo emanzi, njll., ngisho nomsindo wokugeleza kwegazi "awuzwakali" kakhulu ngoba umsindo uphansi kakhulu noma ivolumu iphansi kakhulu, noma ayibonakali. ngendawo enomsindo.

Ngesikhathi se-cardiac auscultation, i-earpiece ye-membrane ingalalela kahle imisindo ye-high-frequency, futhi i-earpiece yohlobo lwenkomishi ifanele ukulalela imisindo ephansi noma ukububula. Ama-stethoscopes anamuhla wonke angama-stethoscope anezinhlangothi ezimbili. Kukhona kokubili ulwelwesi kanye nezinhlobo zenkomishi ekhanda le-auscultation. Ukuguqulwa phakathi kokubili kudinga kuphela ukuzungeziswa ngo-180°. Ochwepheshe basikisela ukuthi odokotela basemtholampilo kufanele basebenzise ama-stethoscope anezinhlangothi ezimbili. Kukhona obunye ubuchwepheshe obunelungelo lobunikazi obubizwa nge-floating membrane technology. Ikhanda le-membrane auscultation lingashintshwa libe yinhloko yendlebe yohlobo lwenkomishi ngendlela ekhethekile ukuze ilalele umsindo we-low-frequency. Yomibili imisindo yamaphaphu evamile kanye nengavamile imisindo yefrikhwensi ephezulu, futhi ulwelwesi lwendlebe kuphela olungasetshenziselwa ukuvuselela amaphaphu.

Izinhlobo ze-stethoscopes

I-Acoustic stethoscope

I-Acoustic stethoscope iyi-stethoscope yokuqala, futhi iyithuluzi lokuxilonga ngezokwelapha elijwayelekile kubantu abaningi. Lolu hlobo lwe-stethoscope luwuphawu lukadokotela, futhi udokotela ulugqoka entanyeni nsuku zonke. Ama-acoustic stethoscopes yiwo asetshenziswa kakhulu.

I-electronic stethoscope

I-electronic stethoscope isebenzisa ubuchwepheshe be-elekthronikhi ukuze ikhulise umsindo womzimba futhi inqobe isiphazamisi somsindo ophezulu we-acoustic stethoscope. I-electronic stethoscope idinga ukuguqula isignali kagesi yomsindo ibe igagasi lomsindo, eliye likhuliswe bese licutshungulwa ukuze uthole ukulalela okungcono kakhulu. Uma kuqhathaniswa nama-acoustic stethoscopes, wonke asekelwe ezimisweni zomzimba ezifanayo. I-electronic stethoscope ingasetshenziswa nohlelo lwe-auscultation olusizwa ngekhompuyutha ukuze kuhlaziywe ukugula komsindo wenhliziyo orekhodiwe noma ukububula kwenhliziyo okumsulwa.

Ukuthwebula i-stethoscope

Amanye ama-stethoscope kagesi afakwe okuphumayo okuqondile komsindo, okungasetshenziswa ukuxhuma kudivayisi yokurekhoda yangaphandle, njengekhompyutha ephathekayo noma i-MP3 rekhoda. Londoloza le misindo futhi ulalele imisindo erekhodiwe ngaphambilini ngehedisethi ye-stethoscope. Udokotela angenza ucwaningo olunzulu ngisho nokuxilongwa kude.

I-Fetal Stethoscope

Eqinisweni, i-fetus stethoscope noma i-fetus scope iwuhlobo lwe-acoustic stethoscope, kodwa idlula i-acoustic stethoscope evamile. I-fetus stethoscope ikwazi ukuzwa izwi le-fetus esiswini sowesifazane okhulelwe. Kuzuzisa kakhulu ukunakekelwa kwabahlengikazi ngesikhathi sokukhulelwa.

I-Doppler stethoscope

I-Doppler stethoscope iyithuluzi le-elekthronikhi elikala umphumela we-Doppler wamagagasi aboniswayo wamagagasi e-ultrasonic avela ezithweni zomzimba. Ukunyakaza kutholwa njengokushintshwa kwemvamisa ngenxa yomphumela we-Doppler, okhombisa igagasi. Ngakho-ke, i-Doppler stethoscope ifaneleka ngokukhethekile ukuphatha izinto ezihambayo, njengenhliziyo eshayayo.
