Nheyo ye stethoscope
Inowanzo kuve nemusoro we auscultation, inonzwika gidhi chubhu, uye nzeve hoko.Ita (frequency) isiri-mutsara amplification yezwi rakaunganidzwa.
Nheyo ye stethoscope ndeyokuti kufambisa kwekudengenyeka pakati pezvinhu kunotora chikamu mufirimu yealuminium mu stethoscope, uye mhepo chete inoshandura frequency uye wavelength yezwi, inosvika pa "kugadzikana" nzeve yemunhu, uye panguva imwe chete. kudzivirira mamwe manzwi uye "kunzwa" zvakajeka.Chikonzero chinoita kuti vanhu vanzwe ruzha ndechekuti iyo inonzi "ruzha" inoreva kuzununguka kwezvinhu, semhepo inozunguza iyo tympanic membrane munzeve yemunhu, iyo inoshandurwa kuita mafungu europi, uye vanhu vanogona "kunzwa" inzwi.Iyo vibration frequency inonzwa nenzeve dzevanhu ndeye 20-20KHZ.
Pane mumwe mupimo wekuona kwevanhu inzwi, inova vhoriyamu, iyo ine chekuita newavelength.Hurukuro hwekunzwa kwevanhu kwakajairika ndeye 0dB-140dB.Mune mamwe mazwi: ruzha rweodhiyo rwakanyanya uye haruna kunzwika, uye odhiyo muhuwandu hwevhoriyamu idiki kwazvo (yakaderera frequency waves) kana yakakura kwazvo (yakanyanya frequency masaisa) kuti inzwe.
Ruzha rwunogona kunzwiwa nevanhu rwune chekuitawo nemhoteredzo.Nzeve yomunhu inodzivirira, ndiko kuti, manzwi ane simba anogona kuvhara ruzha rusina simba.Ruzha rwuri mukati memuviri wemunhu, sekurova kwemoyo, kurira kwemudumbu, kunyorova, zvichingodaro, uye kunyangwe ruzha rwekuyerera kweropa "harunzwike" zvakanyanya nekuti ruzha rwakanyanya kuderera kana vhoriyamu yakadzikira, kana kuvharika. nemhoteredzo ine ruzha.
Munguva yemoyo auscultation, membrane yenzeve inogona kuteerera kune yakakwira-frequency inonzwika zvakanaka, uye mukombe-mhando yenzeve yakakodzera kuteerera kune yakaderera-frequency ruzha kana kugunun'una.Mazuva ano stethoscopes ese ari maviri-sided stethoscopes.Kune ese ari maviri membrane nemhando dzekapu pamusoro we auscultation.Iko kutendeuka pakati pezviviri kunongoda kutenderedzwa ne180 °.Nyanzvi dzinoratidza kuti vanachiremba vekiriniki vanofanirwa kushandisa maviri-sided stethoscopes.Kune imwe tekinoroji ine patent inodaidzwa kuti inoyangarara membrane tekinoroji.Musoro we membrane auscultation unogona kuchinjwa kuva musoro wemukombe-mhando yenzeve nenzira yakakosha yekuteerera kune yakaderera-frequency ruzha.Zvese zviri zviviri zvakajairwa uye zvisina kujairika ruzha rwemapapu manzwi akakwira-frequency, uye chete membrane nzeve ndiyo inogona kushandiswa kuita mapapu auscultation.
Mhando dze stethoscopes
Acoustic stethoscope
Acoustic stethoscope ndiyo yekutanga stethoscope, uye zvakare chishandiso chekurapa chekuongorora chinozivikanwa nevanhu vazhinji.Rudzi urwu rwe stethoscope chiratidzo chechiremba, uye chiremba anopfeka pamutsipa mazuva ese.Acoustic stethoscopes ndiyo inonyanya kushandiswa.
Electronic stethoscope
Iyo yemagetsi stethoscope inoshandisa tekinoroji yemagetsi kukwidziridza ruzha rwemuviri uye kukunda iyo ruzha bug yeacoustic stethoscope.Iyo yemagetsi stethoscope inoda kushandura chiratidzo chemagetsi chekurira kune ruzha wave, iyo inobva yawedzerwa nekugadziriswa kuti iwane kunyatsoteerera.Kuenzaniswa neacoustic stethoscopes, ese akavakirwa pamitemo yakafanana yemuviri.Iyo yemagetsi stethoscope inogona zvakare kushandiswa nekombuta-inobatsirwa auscultation chirongwa chekuongorora yakarekodhwa moyo ruzha pathology kana isina mhosva kugunun'una.
Kutora mifananidzo stethoscope
Mamwe maelectronic stethoscopes akashongedzerwa neakananga kuburitsa audio, iyo inogona kushandiswa kubatanidza kune yekunze yekurekodha mudziyo, senge laptop kana MP3 rekodhi.Sevha manzwi aya uye teerera kune yakamborekodhwa manzwi kuburikidza neiyo stethoscope headset.Chiremba anogona kuita tsvakiridzo yakadzama uye kunyange kuongororwa kure.
Fetal Stethoscope
Sezvineiwo, fetal stethoscope kana fetal scope imhando yeacoustic stethoscope, asi inodarika yakajairwa acoustic stethoscope.Iyo fetal stethoscope inogona kunzwa izwi re "fetus" mudumbu remukadzi ane pamuviri.Inobatsira zvikuru pakuchengeta mukoti panguva yekuzvitakura.
Doppler stethoscope
A Doppler stethoscope chinhu chemagetsi chinoyera iyo Doppler mhedzisiro yemafungu anotaridza emafungu e ultrasonic kubva kunhengo dzemuviri.Iko kufamba kunoonekwa sekuchinja kwefrequency nekuda kweiyo Doppler mhedzisiro, inoratidza wave.Naizvozvo, iyo Doppler stethoscope inonyanya kukodzera kubata zvinhu zvinofamba, senge moyo unorova.
