Ihame rya stethoscope

Ubusanzwe igizwe n'umutwe wa auscultation, umuyoboro uyobora amajwi, hamwe n'amatwi.Kora (inshuro) itari umurongo wo kwongera amajwi yakusanyijwe.

Ihame rya stethoscope nuko ihererekanyabubasha hagati yibintu bigira uruhare muri firime ya aluminium muri stethoscope, kandi umwuka wonyine uhindura inshuro nuburebure bwijwi ryijwi, ukagera kumurongo "woroshye" ugutwi kwabantu, kandi mugihe kimwe. gukingira andi majwi no "kumva" birasobanutse.Impamvu ituma abantu bumva amajwi nuko ibyo bita "amajwi" bivuga kunyeganyega kw'ibintu, nk'umwuka unyeganyega wa tympanic membrane mu gutwi k'umuntu, bigahinduka mu bwonko, kandi abantu bashobora "kumva" the ijwi.Inshuro yinyeganyeza amatwi yumuntu ashobora kumva ni 20-20KHZ.

Hariho ikindi gipimo cyimyumvire yumuntu yijwi, nubunini, bujyanye nuburebure.Ubwinshi bwurwego rwo kwumva kwabantu ni 0dB-140dB.Muyandi magambo: amajwi murwego rwamajwi arasakuza cyane kandi afite intege nke kuburyo atumva, kandi amajwi murwego rwijwi ni nto cyane (imirongo mike yumurongo muto) cyangwa nini cyane (umurongo mwinshi wumurongo) kugirango utumva.

Ijwi abantu bashobora kumva naryo rijyanye nibidukikije.Ugutwi kwa muntu bigira ingaruka zo gukingira, ni ukuvuga amajwi akomeye arashobora gupfuka amajwi adakomeye.Ijwi imbere mumubiri wumuntu, nkumutima wumutima, amajwi yo munda, rale itose, nibindi, ndetse nijwi ryamaraso ntabwo "byunvikana" cyane kuko amajwi ari make cyane cyangwa amajwi ari make, cyangwa arahishe n'ibidukikije bisakuza.

Mugihe c'umutima auscultation, urutoki rwa membrane rushobora gutegera neza amajwi menshi, kandi igikombe cyubwoko bwigikombe gikwiriye kumva amajwi make cyangwa kwitotomba.Stethoscopes igezweho ni stetoskopi ebyiri.Hano haribintu byombi nibikombe kumutwe wa auscultation.Guhindura hagati yabyo gusa bigomba kuzunguruka kuri 180 °.Abahanga bavuga ko abaganga b’amavuriro bagomba gukoresha stethoscope ebyiri.Hariho ubundi buhanga bwa patenti bwitwa floating membrane technology.Umutwe wa membrane auscultation urashobora guhinduka mumutwe wigikombe cyubwoko bwamatwi muburyo bwihariye bwo kumva urusaku ruke.Byombi amajwi asanzwe kandi adasanzwe ni amajwi menshi, kandi ugutwi kwonyine kurashobora gukoreshwa muguhaha ibihaha.

Ubwoko bwa stethoscopes

Acoustic stethoscope

Acoustic stethoscope ni stethoscope ya mbere, kandi nigikoresho cyo gusuzuma ubuvuzi kimenyerewe kubantu benshi.Ubu bwoko bwa stethoscope ni ikimenyetso cya muganga, kandi umuganga yambara ijosi buri munsi.Acoustic stethoscopes niyo ikoreshwa cyane.

Ikoreshwa rya elegitoroniki

Stethoscope ya elegitoronike ikoresha tekinoroji ya elegitoronike kugirango yongere ijwi ryumubiri kandi itsinde urusaku rwinshi rwa acoustic stethoscope.Stethoscope ya elegitoronike ikeneye guhindura ibimenyetso byamashanyarazi yijwi kumajwi, hanyuma ikongerwaho kandi igatunganywa kugirango yumve neza.Ugereranije na acoustic stethoscopes, byose bishingiye kumahame amwe.Stethoscope ya elegitoroniki irashobora kandi gukoreshwa hamwe na mudasobwa ifashwa na mudasobwa kugirango isesengure amajwi yanditswemo yumutima cyangwa kwitotomba k'umutima.

Gufotora stethoscope

Stethoscopes zimwe za elegitoronike zifite ibikoresho bisohora amajwi bitaziguye, bishobora gukoreshwa muguhuza ibyuma bifata amajwi hanze, nka mudasobwa igendanwa cyangwa MP3.Bika aya majwi hanyuma wumve amajwi yafashwe mbere ukoresheje na stethoscope.Muganga arashobora gukora ubushakashatsi bwimbitse ndetse no kwisuzumisha kure.

Fetal Stethoscope

Mubyukuri, uruhinja rwitwa stethoscope cyangwa urwego rwuruhinja narwo ni ubwoko bwa stethoscope, ariko burenze stethoscope isanzwe.Uruhinja stethoscope irashobora kumva ijwi ryuruhinja mu nda yumugore utwite.Nibyiza cyane kwita kubuforomo mugihe utwite.

Doppler stethoscope

Doppler stethoscope nigikoresho cya elegitoroniki gipima ingaruka ya Doppler yumuraba ugaragara wumuraba wa ultrasonic uva mubice byumubiri.Imyitwarire igaragara nkimpinduka zinshyi bitewe ningaruka ya Doppler, yerekana umuraba.Kubwibyo, Doppler stethoscope irakwiriye cyane cyane mugukora ibintu byimuka, nkumutima utera.
