Nheyo ye stethoscope
Inowanzo kuve nemusoro we auscultation, inzwi rekutungamira chubhu, uye nzeve hoko.Ita (frequency) isiri-mutsara yekusimudza yezwi rakaunganidzwa.
Nheyo yeiyo stethoscope ndeyokuti kufambisa kwemhepo pakati pezvinhu kunotora chikamu mufirimu realuminium mu stethoscope, uye mhepo chete inoshandura frequency uye wavelength yeruzha, inosvika kune "yakagadzikana" 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 tympanic membrane iri munzeve yemunhu, iyo inoshandurwa kuita mafungu europi, uye vanhu vanogona "kunzwa" inzwi.Iyo vibration frequency iyo nzeve dzevanhu dzinogona kunzwa ndeye 20-20KHZ.
Pane mumwe mupimo wekuona kwevanhu inzwi, inova vhoriyamu, iyo ine chekuita newavelength.Hurukuro hwekunzwa kwakajairika kwevanhu ndeye 0dB-140dB.Mune mamwe mazwi: ruzha rwuri murwiyo rweodhiyo rwakanyanya uye rusina simba kuti runzwe, 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 manzwi asina simba.Ruzha rwuri mukati memuviri wemunhu, sekurova kwemoyo, kurira kwemudumbu, kunyorova, nezvimwewo, 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 yakakwirira-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 nekapu mhando pamusoro we auscultation.Iko kutendeuka pakati pezviviri kunongoda kutenderedzwa ne180 °.Nyanzvi dzinokurudzira kuti vanachiremba vekiriniki vanofanira kushandisa maviri-sided stethoscopes.Pane imwe patented tekinoroji inonzi inoyangarara membrane tekinoroji.Musoro we membrane auscultation unogona kuchinjwa kuva musoro wemukombe-yemhando yenzeve nenzira yakakosha yekuteerera kune yakaderera-frequency ruzha.Zvese zviri zviviri zvinonzwika uye zvisina kujairika mapapu manzwi akakwira-frequency kurira, uye chete membrane nzeve inogona kushandiswa pamapapu 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 inozowedzerwa 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 rekodha.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.
