Ithubhu yokumunca esetshenziswa kanye isetshenziselwa iziguli zasemtholampilo ukuthatha isikhwehlela noma uketshezi oluvela ku-trachea. Umsebenzi wokumunca wethubhu yokumunca esetshenziswa kanye kufanele ube lula futhi uzinzile. Isikhathi sokumunca akufanele sidlule imizuzwana eyi-15, futhi idivayisi yokumunca akufanele ihlale imizuzu engaphezu kwemi-3.
Indlela yokusebenza kwepayipi lokumunca elisetshenziswa kanye kuphela:
(1) Hlola ukuthi uxhumano lwengxenye ngayinye yedivayisi yokumunca luphelele yini futhi akukho ukuvuza komoya. Vula amandla, vula iswishi, hlola ukusebenza kwe-aspirator, bese ulungisa ingcindezi engemihle. Ngokuvamile, ingcindezi yokumunca yomuntu omdala icishe ibe ngu-40-50 kPa, ingane imunca cishe u-13-30 kPa, bese ipayipi lokumunca elilahlwayo lifakwa emanzini ukuhlola ukukhanga nokuhlanza ipayipi lesikhumba.
(2) Phendukisa ikhanda lesiguli kumhlengikazi bese usakaza ithawula lokwelapha ngaphansi komhlathi.
(3) Faka ithubhu lokumunca elilahlwayo ngokulandelana kwevestibule yomlomo→izihlathi→ipharynx, bese ukhipha izingcezu. Uma kunzima ekumunceni ngomlomo, lingafakwa ngembobo yamakhala (iziguli ezingavunyelwe ukuphuka kwesisekelo sekhanda), uhlelo luqala evestibule yamakhala liye endaweni engezansi yamakhala → indawo engemuva yamakhala → ipharynx → i-trachea (cishe amasentimitha angama-20-25), bese uketshezi lumuncwa ngalunye. Kwenze. Uma kukhona i-intubation ye-tracheal noma i-tracheotomy, i-sputum ingafuthwa ngokufaka ku-cannula noma ku-cannula. Isiguli esinesifo sokuwa singavula umlomo ngesivikelo solimi noma ngomshini wokuvula ngaphambi kokudonsela.
(4) Ukumunca ngaphakathi komgudu wokuphefumula, lapho isiguli siphefumula, faka ngokushesha i-catheter, ujikeleze i-catheter kusukela phansi kuya phezulu, bese ususa uketshezi lomoya, bese ubheka ukuphefumula kwesiguli. Ngesikhathi sokukhanga, uma isiguli sikhwehlela kabi, linda isikhashana ngaphambi kokumunca. Hlanza ipayipi lokumunca nganoma yisiphi isikhathi ukuze ugweme ukuvaleka.
(5) Ngemva kokumunca, vala inkinobho yokumunca, lahla ipayipi lokumunca elisemgqonyeni omncane, bese udonsela ingilazi yepayipi ebhareni lombhede ukuze ibe sebhodleleni lokuhlanza amagciwane, bese usula umlomo wesiguli nxazonke. Bheka inani, umbala kanye nohlobo lwe-aspirate bese ubhala phansi njengoba kudingeka.
Ishubhu lokumunca elilahlwayo liwumkhiqizo ongcolile, ohlanzwa nge-ethylene oxide bese uhlanzwa iminyaka emi-2. Kunqunyelwe ukusetshenziswa kanye kuphela, kubhujiswe ngemva kokusetshenziswa, futhi kuvinjelwe ukusetshenziswa okuphindaphindiwe. Ngakho-ke, ishubhu lokumunca elilahlwayo alidingi ukuthi isiguli sizihlanze futhi sizibulale amagciwane.
