Ihame rya stethoscope

Ubusanzwe igizwe n'umutwe wa auscultation, umuyoboro uyobora amajwi, hamwe n'amatwi. Kora (inshuro) itari kumurongo amplification yijwi ryegeranijwe.

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" w ugutwi kwabantu, kandi mugihe kimwe. gukingira andi majwi no "kumva" birasobanutse. Impamvu abantu bumva amajwi nuko icyitwa "amajwi" bivuga kunyeganyega kwingingo zingingo, nkumwuka uhinda umusemburo wa tympanic mumatwi yumuntu, ugahinduka mumigezi yubwonko, kandi abantu barashobora "kumva" ijwi. Inshuro yinyeganyeza amatwi yumuntu ashobora kumva ni 20-20KHZ.

Hariho ikindi gipimo cyimyumvire yumuntu yijwi, nubunini, bujyanye nuburebure. Imbaraga zingana zo kumva bisanzwe kwabantu ni 0dB-140dB. Muyandi magambo: amajwi ari murwego rwamajwi arasakuza cyane kandi afite intege nke kuburyo atumva, kandi amajwi murwego rwijwi ni nto cyane (imirongo yumurongo muto) cyangwa nini cyane (umurongo mwinshi cyane) kugirango utumva.

Ijwi abantu bashobora kumva naryo rifitanye isano nibidukikije. Ugutwi kwa muntu bigira ingaruka zo gukingira, ni ukuvuga amajwi akomeye arashobora gupfuka amajwi adakomeye. Ijwi riri imbere mu mubiri w'umuntu, nk'umutima utera, amajwi yo mu mara, imitsi itose, n'ibindi, ndetse n'ijwi ry'amaraso ntabwo "byumvikana" cyane kuko amajwi ari make cyane cyangwa amajwi akaba ari make, cyangwa akaba adafunze n'ibidukikije bisakuza.

Mugihe c'umutima auscultation, urutoki rwa membrane rushobora kumva amajwi yumurongo mwinshi neza, kandi igikombe cyubwoko bwigikombe gikwiranye no kumva amajwi make cyangwa kwitotomba. Stethoscopes igezweho ni stethoscopes ebyiri. Hano haribintu byombi nibikombe kumutwe wa auscultation. Guhindura byombi bigomba gusa kuzunguruka kuri 180 °. Abahanga bavuga ko abaganga b’amavuriro bagomba gukoresha stethoscopes 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. Amajwi y'ibihaha asanzwe kandi adasanzwe ni amajwi menshi cyane, kandi ugutwi kwa membrane gusa niyo ishobora gukoreshwa muguhaha ibihaha.

Ubwoko bwa stethoscopes

Stethoscope

Acoustic stethoscope niyo stethoscope yambere, kandi nigikoresho cyo gusuzuma ubuvuzi kimenyerewe kubantu benshi. Ubu bwoko bwa stethoscope ni ikimenyetso cya muganga, kandi umuganga ayambara ku ijosi buri munsi. Stethoscopes ya Acoustic niyo ikoreshwa cyane.

Stethoscope

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 stethoscopes acoustic, byose bishingiye kumahame amwe. Stethoscope ya elegitoronike irashobora kandi gukoreshwa hamwe na gahunda ya mudasobwa ifashwa na mudasobwa kugirango isesengure amajwi y’umutima yanditswemo cyangwa kwitotomba k'umutima w'inzirakarengane.

Gufotora stethoscope

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

Fetal Stethoscope

Mubyukuri, uruhinja rwa stethoscope cyangwa urwego rwuruhinja narwo ni ubwoko bwa stethoscope acoustic, 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 elegitoronike gipima ingaruka ya Doppler yumuraba ugaragara wumuraba wa ultrasonic uva mubice byumubiri. Imyiyerekano igaragara nkimpinduka zinshyi bitewe ningaruka ya Doppler, yerekana umuraba. Kubwibyo, Doppler stethoscope irakwiriye cyane cyane mugukoresha ibintu byimuka, nkumutima utera.
