Imikhiqizo

I-transducer yomfutho wegaziiyithuluzi lezokwelapha elisetshenziselwa ukukala umfutho wegazi ngokuguqula amandla asetshenziswa ukugeleza kwegazi abe isignali kagesi. Kuyingxenye eyinhloko ezinhlelweni zokuqapha umfutho wegazi ohlaselayo, ovame ukusetshenziswa ezindaweni zokunakekelwa okubucayi njengamagumbi okuhlinza, amayunithi okunakekela kakhulu (ICUs), kanye neminyango yezimo eziphuthumayo.

Amashubhu axhumayoyizici ezibalulekile ezisetshenziswa kumishini nezinhlelo ezihlukahlukene zokuthutha uketshezi, amagesi, noma imithi emzimbeni noma phakathi kwemishini yezokwelapha. Lawa mashubhu aklanyelwe ukuhlangabezana nezindinganiso eziqinile zokuphepha kanye ne-biocompatibility ukuqinisekisa ukuphepha kwesiguli kanye nokwelashwa okuphumelelayo.

I-stopcock yezindlela ezintathu isetshenziselwa ukuxhuma nemishini yokufaka ukuze kuxhunywe futhi kulawulwe ukujova ngomthambo, ukulinganisa ingcindezi nokunye.I-stopcock inezikhala ezintathu (izimbobo) ezingaxhunywa kumashubhu, amasirinji, noma ezinye izinto zokwelapha. Isibambo esimaphakathi noma i-lever ivumela abahlinzeki bezempilo ukuthi balawule indlela yokuhamba ngokuyizungezisa ukuze iqondaniswe nezimbobo ezithile.

Uhlelo lokumunca oluvaliwe olulahlwayo isetshenziswa ukuxhuma nesistimu ye-vacuum negative pressure noma okokusebenza komgudu wokuphefumula ukuheha isikhwehlela.

GIsipetu se-uidewireiyisisetshenziswa sezokwelapha esikhethekile esisetshenziswa phakathi nezinqubo ezibandakanya ukufakwa kwentambo yocingo, njengokufakwa kwe-venous catheter emaphakathi, ukufakwa komugqa we-arterial, noma ezinye izinqubo zokufinyelela emithanjeni. Iklanyelwe ukwenza lula ukuthuthuka okushelelayo nokuphephile kwe-guidewire emkhunjini.
