Kugirango tugaragaze ko sensor yacu ishobora gukurikirana neza kandi neza ibimenyetso byerekana ibimenyetso byubuhumekero, twakoze ubushakashatsi bwo kugereranya ibisubizo byo gupima ibimenyetso byimpiswi nubuhumekero hagati ya TATSAs nigikoresho gisanzwe cyubuvuzi (MHM-6000B), nkuko byasobanuwe muri firime S8 na S9.Mu gupima impanuka ya pulse, sensor ya fotoelectric igikoresho cyubuvuzi yambaraga kurutoki rwibumoso rwumukobwa ukiri muto, kandi hagati aho, TATSA yacu yari yambaye kurutoki rwe rwiburyo.Duhereye kubintu bibiri byabonetse, dushobora kubona ko imiterere yabyo hamwe nibisobanuro byayo byari bimwe, byerekana ko impiswi zapimwe na TATSA zisobanutse neza nkiz'ibikoresho byubuvuzi.Mu gupima imiyoboro y'ubuhumekero, electrode eshanu za electrocardiografique zometse ku bice bitanu ku mubiri w'umusore ukurikije amabwiriza y'ubuvuzi.Ibinyuranye, TATSA imwe gusa yari ihambiriye kumubiri kandi ikingira igituza.Duhereye ku bimenyetso by'ubuhumekero byakusanyirijwe hamwe, birashobora kugaragara ko impinduka zitandukanye nigipimo cyibimenyetso byubuhumekero byamenyekanye na TATSA yacu byari bihuye nibyo nibikoresho byubuvuzi.Ubu bushakashatsi bubiri bwo kugereranya bwemeje ukuri, kwiringirwa, no koroshya sisitemu ya sensor yacu yo gukurikirana impyiko nibimenyetso byubuhumekero.

Byongeye kandi, twahimbye umwenda wubwenge kandi dushushanya TATSA ebyiri kumubyimba no mu kuboko kugirango dukurikirane ibimenyetso byubuhumekero na pulse.By'umwihariko, WMHMS yatejwe imbere ikoreshwa mu gufata icyarimwe ibimenyetso byubuhumekero icyarimwe.Binyuze muri ubu buryo, twabonye ibimenyetso byubuhumekero na pulse byumusore wimyaka 25 wambaye imyenda yacu yubwenge dusinziriye (Igicapo 5D na firime S10) yicaye (igishusho S26 na firime S11).Ibimenyetso byubuhumekero na pulse byabonetse bishobora koherezwa kuri APP ya terefone igendanwa.Nkuko byavuzwe haruguru, TATSA ifite ubushobozi bwo gufata ibimenyetso byubuhumekero na pulse.Ibi bimenyetso byombi bya physiologique nabyo ni byo bipimo byo kugereranya SAS mubuvuzi.Kubwibyo, TATSA yacu irashobora kandi gukoreshwa mugukurikirana no gusuzuma ireme ryibitotsi nibibazo bijyanye no gusinzira.Nkuko bigaragara ku gishushanyo cya 5 (E na F, uko bikurikirana), twakomeje gupima impiswi n’ubuhumekero bw’abantu babiri bitabiriye amahugurwa, umwe muzima n’umurwayi ufite SAS.Ku muntu udafite apnea, ibipimo by'ubuhumekero na pulse byapimwe byagumye bihamye kuri 15 na 70.Ku murwayi urwaye SAS, apnea itandukanye kuri 24 s, ikaba yerekana ibimenyetso byubuhumekero bubangamira, byagaragaye, kandi umuvuduko wumutima wiyongereyeho gato nyuma yigihe cya apnea kubera kugenga sisitemu yimitsi (49).Muncamake, imiterere yubuhumekero irashobora gusuzumwa na TATSA yacu.

Kugirango turusheho gusuzuma ubwoko bwa SAS dukoresheje ibimenyetso byubuhumekero nubuhumekero, twasesenguye igihe cyo gutambutsa impiswi (PTT), ikimenyetso kidahwitse kigaragaza impinduka ziterwa no kurwanya imitsi ya periferique hamwe nigitutu cya intrathoracic (bisobanurwa mu gice cya S1) cyumugabo muzima numurwayi ufite SAS.Ku bitabiriye ubuzima bwiza, igipimo cy’ubuhumekero nticyahindutse, kandi PTT yari ihagaze neza kuva ms 180 kugeza 310 (Ishusho 5G).Ariko, kubitabiriye SAS, PTT yiyongereye kuva kuri 120 kugera kuri 310 ms mugihe cya apnea (Ishusho 5H).Rero, abitabiriye amahugurwa basuzumwe SAS (OSAS) ibangamira.Niba impinduka muri PTT yagabanutse mugihe cya apnea, noneho imiterere yagenwa nka syndrome yo hagati yo gusinzira apnea (CSAS), kandi niba ibyo bimenyetso byombi byarabaye icyarimwe, noneho byasuzumwa nka SAS ivanze (MSAS).Kugirango dusuzume uburemere bwa SAS, twongeye gusesengura ibimenyetso byakusanyijwe.Indangantego ya PTT, numubare wibyuka bya PTT kumasaha (PTT kubyutsa bisobanurwa nko kugwa muri PTT ya ms15 ms bimara ≥3 s), bigira uruhare runini mugusuzuma urwego rwa SAS.Indwara ya apnea-hypopnea (AHI) ni igipimo cyo kumenya urugero rwa SAS (apnea ni uguhagarika guhumeka, kandi hypopnea ni uguhumeka gukabije cyangwa umuvuduko w'ubuhumekero udasanzwe), bisobanurwa nk'umubare wa apneas na hypopnea kuri buri isaha uryamye (isano iri hagati ya AHI n'ibipimo ngenderwaho bya OSAS irerekanwa mumeza S2).Kugira ngo hakorwe iperereza ku isano iri hagati ya AHI n’ikimenyetso cyo kubyutsa PTT, ibimenyetso by’ubuhumekero by’abarwayi 20 barwaye SAS byatoranijwe kandi bisesengurwa na TATSAs.Nkuko bigaragara ku gishushanyo cya 5I, indangagaciro ya PTT ifitanye isano neza na AHI, kuko apnea na hypopnea mugihe cyo gusinzira bitera umuvuduko ukabije w umuvuduko wamaraso, bigatuma PTT igabanuka.Kubwibyo, TATSA yacu irashobora kubona impiswi zihamye kandi zukuri hamwe nibimenyetso byubuhumekero icyarimwe, bityo bigatanga amakuru yingenzi ya physiologique kuri sisitemu yumutima nimiyoboro y'amaraso na SAS mugukurikirana no gusuzuma indwara zifitanye isano.

Muri make, twateje imbere TATSA dukoresheje ubudodo bwuzuye bwa karigisi kugirango tumenye ibimenyetso bitandukanye bya fiyologiki icyarimwe.Iyi sensor yagaragazaga ibyiyumvo bihanitse bya 7.84 mV Pa - 1, igihe cyihuse cyo gusubiza ms 20, guhagarara kwinshi kwinzira zirenga 100.000, hamwe numuyoboro mugari wakazi.Hashingiwe kuri TATSA, hashyizweho kandi WMHMS yohereza ibipimo bya physiologi byapimwe kuri terefone igendanwa.TATSA irashobora kwinjizwa mumyanya itandukanye yimyenda kugirango ibe nziza kandi ikoreshwa mugukurikirana icyarimwe ibimenyetso byimpyiko nibihumeka mugihe nyacyo.Sisitemu irashobora gukoreshwa kugirango ifashe gutandukanya abantu bafite ubuzima bwiza nabafite CAD cyangwa SAS kubera ubushobozi bwayo bwo gufata amakuru arambuye.Ubu bushakashatsi bwatanze uburyo bwiza, bunoze, kandi bworohereza abakoresha gupima impemu zabantu nubuhumekero, byerekana iterambere mugutezimbere ibikoresho bya elegitoroniki byambara.

Icyuma kidafite ingese cyanyujijwe inshuro nyinshi hanyuma kiramburwa kugira fibre ifite umurambararo wa mm 10.Fibre idafite ingese nkuko electrode yinjijwe mubice byinshi byubucuruzi bumwe gusa bwa Terylene.

Imashini itanga amashanyarazi (Stanford DS345) hamwe na amplifier (LabworkPa-13) yakoreshejwe mugutanga ikimenyetso cyumuvuduko wa sinusoidal.Ikoreshwa ryimbaraga ebyiri (Vernier Software & Technology LLC) yakoreshejwe mu gupima umuvuduko wo hanze ukoreshwa kuri TATSA.Sisitemu ya Keithley ya electrometero (Keithley 6514) yakoreshejwe mugukurikirana no gufata amajwi asohoka na voltage ya TATSA.

Dukurikije uburyo bwa test ya AATCC 135-2017, twakoresheje TATSA na ballast ihagije nkumutwaro wa kg 1.8 hanyuma tuyishyira mumashini imesa ibicuruzwa (Labtex LBT-M6T) kugirango dukore imashini zamesa.Hanyuma, twujuje imashini imesa litiro 18 zamazi kuri 25 ° C hanyuma dushyira igikarabiro cyatoranijwe cyo gukaraba nigihe (umuvuduko wo guhagarika umutima, inkoni 119 kumunota; igihe cyo gukaraba, 6 min; umuvuduko wanyuma, 430 rpm; umwanya wo kuzunguruka, iminota 3)Ubwa nyuma, TATSA yamanitswe yumutse mu kirere gituje ku bushyuhe bwo mu cyumba butarenze 26 ° C.
