Ukufunxa isikhohlela lolunye lwemisebenzi exhaphakileyo yokonga kwaye yindlela esebenzayo yokucoca ulwelo lokuphefumla.Kulo msebenzi, ityhubhu yokufunxa idlala indima ebalulekileyo.Nangona kunjalo, unolwazi olungakanani ngayo?

Yintoni ityhubhu yokufunxa?

Ityhubhu yokufunxa yenziwe ngezinto zepolymer zonyango kwaye yenziwe ngecatheter, ivalve yokulawula ukufunxa kunye neziqhagamshelo (isiqhagamshelo seconical, ikhonkco eligobileyo, isidibanisi esipelwe ngesandla, isidibanisi sevalvu, isinxibelelanisi sohlobo lwaseYurophu) ukususa isikhohlela esiphuma kumzila womoya kwityhubhu ye-tracheostomy ukwenza umzila womoya uvuleke.Eminye imibhobho yokufunxa inomsebenzi wokuqokelela nokugcina ezi ncindi.

Ngaphandle koko, ityhubhu efunxayo elahlwayo yimveliso engenazintsholongwane, ivalwe nge-ethylene.Inqunyelwe ekusebenziseni okukodwa kwaye inqatshelwe ukusetyenziswa kwakhona.Ityhubhu enye yomntu omnye kwaye akukho mfuneko yokucoca kunye nokucoca inzala kwakhona, eyona nto ilula kwaye icocekile.

Ityhubhu yokufunxa isetyenziselwa ukukhupha isikhohlela kunye nezinye iimfihlo kwi-trachea ukuthintela izigulane ekuthinteleni umsebenzi wokuphefumula, i-asphyxia kunye nokungaphumeleli kokuphefumula.Izigulane zicetyiswa ukuba ziyisebenzise phantsi kwesikhokelo soogqirha kwizibhedlele zengcali kunokuba ziyisebenzise ngasese ukuphepha ukubangela enye ingozi enkulu kwimizimba yazo ngenxa yokusetyenziswa kakubi.

Iityhubhu zokufunxa zinokwahlulwa zibe ziimodeli ezintandathu ngokobubanzi bazo: F4, F6, F8, F10, F12 kunye neF16.Ukuthintela ukwenzeka kwe-aspiration pneumonia, imodeli efanelekileyo yombhobho kufuneka ikhethwe ngokwemeko ethile yesigulane ukuphepha umonakalo we-airway mucosal kunye nokusuleleka kwesibini.

Indlela yokukhetha iityhubhu zokufunxa

Kuphela xa ukhetha ityhubhu yokufunxa efanelekileyo ingaba luncedo kwaye ingenzi monakalo kwizigulane.Ngoko ke ukhetho lwetyhubhu yokufunxa lunezi mfuno zingezantsi:

I-1.Izinto eziphathekayo zombhobho wokufunxa kufuneka zingabi yingozi kwaye zingabi yingozi emzimbeni womntu, kwaye ukuthungwa kufuneka kube thambileyo, ukwenzela ukunciphisa umonakalo kwi-mucosa kunye nokuququzelela ukusebenza.
2.Ityhubhu yokufunxa kufuneka ibenobude obaneleyo ukuvumela ukulangazelela kwangexesha nokwaneleyo kwesikhohlela ukuze sifikelele emazantsi eendlela zomoya ezinzulu.
3.Ubukhulu bombhobho wokufunxa akufunekanga ube mde okanye ube mfutshane kakhulu.Singakhetha ityhubhu yokufunxa enobubanzi obumalunga ne-1-2 cm yokufunxa isikhohlela.Ubukhulu bombhobho wokufunxa akufunekanga bugqithe kwisiqingatha sedayamitha yendlela yomoya eyenziweyo kakhulu.

Kubalulekile ukuqaphela ukuba ityhubhu yokufunxa enemingxuma emacaleni ayinakwenzeka ukuba ithintelwe yincindi ngexesha lokufunxa isikhohlela.Impembelelo yayo ingcono kuneetyhubhu ezinemingxuma esecaleni kunye ne-lager imingxuma esecaleni, isiphumo singcono.Idayamitha pf ityhubhu yokufunxa inkulu, ukuthomalaliswa koxinzelelo olubi kwindlela yomoya kuya kuba ncinci kwaye umphumo wokufunxa uya kuba ngcono, kodwa ukuwa komphunga okubangelwa ngexesha lenkqubo yokufunxa kuya kuba nzima ngakumbi.

Xa sisebenzisa iityhubhu zokufunxa, kufuneka siqaphele ukuba sizisebenzisa ixesha elingakanani.Ubude bexesha lokufunxa isikhohlela akufunekanga budlule imizuzwana eyi-15 ngexesha, kwaye ikhefu kufuneka libe ngaphezu kwemizuzu emi-3 ekufunxeni isikhohlela ngasinye.Ukuba ixesha lifutshane kakhulu, kuya kubangela umnqweno ongalunganga;Ukuba ixesha lide kakhulu, liya kubangela ukungahambi kakuhle kwisigulane kunye nobunzima bokuphefumula.

Ukuvelisa njani iityhubhu zokufunxa

Njengesixhobo esibalulekileyo sonyango, inkqubo yokuvelisa kunye nokusingqongileyo kweetyhubhu zokufunxa kufuneka zilawulwe ngokungqongqo, kwaye njengemveliso yonyango ebalulekileyo, umthamo ophezulu wokuvelisa uyafuneka ukuhlangabezana nemfuno yemarike.

Umatshini wokuvelisa ityhubhu ye-Hengxingli inokuvelisa iityhubhu ezintandathu ngexesha, kwaye inokudibanisa, isike kwaye incamathele isinxibelelanisi kumbhobho.Izihlanganisi zigxininiswe ngokuqinileyo nge-cyclic ketone glue.Isiqhagamshelo sophondo kunye ne-airplane-shaped connector iyakhethwa ngokweemfuno.Umatshini unokuzenza ngokuzenzekelayo yonke inkqubo yemveliso, kwaye utshintshe ngokuzenzekelayo amazibuko okutyisa izinto ukuqinisekisa ukuba akayi kuyeka xa ukongeza okanye ukutshintsha izinto.Ikwayilwe kunye nesakhiwo sokubethelwa esichanekileyo ukufezekisa ukuhambelana okuphezulu kwemveliso.

Ukongezelela, ukuhambelana okuphezulu komatshini kuvumela ukuveliswa kwanoma yimuphi ubungakanani kunye nokucaciswa kweetyhubhu ngaphandle kokutshintsha isikhunta.Umatshini unokudityaniswa nomgca wokupakisha kunye nenkqubo yokuhlola imveliso ngokuzenzekelayo ngokweemfuno zemveliso, okwenza kube yindleko esebenzayo yokuvelisa umatshini wokwenza ityhubhu.
