I-catheter ingumshini wezokwelapha we-Class II, ishubhu elifakwe esinyeni nge-urethra ukuze kukhishwe umchamo, ikakhulukazi esetshenziselwa iziguli ezinokuvaleka komchamo noma ezivimba ukuphuma kwesinye isinye, ukungakwazi ukuchama, iziguli ezidinga ukuphumula kombhede isikhathi eside noma isikhundla esiphoqelelwe, kanye neziguli. esikhathini se-perioperative yezinqubo zokuhlinzwa.Ama-catheter avame ukuhlukaniswa abe amamodeli angu-13 anezincazelo ezisukela ku-6F kuya ku-30F ngokuvumelana nomjikelezo we-diameter yangaphandle, futhi amamodeli amane we-12F, 14F, 16F kanye no-18F avame ukusetshenziswa kubantu abadala.

Izinto ze-catheter

Ama-catheter enziwe ngokuyinhloko nge-polyvinyl chloride, i-silicone, i-latex, njll. Ama-catheter enziwe ngezinto ezihlukahlukene anezici ezihlukene:

I-Polyvinyl chloride (i-PVC): umkhiqizo unzima, uyacasula, ukuzwa okuqinile komzimba wangaphandle futhi akubizi, Lo mkhiqizo ikakhulukazi awunamabhaluni futhi awuhambisani kahle ne-biocompatible, uthambekele ekunamatheleni, futhi ungashiywa isikhathi esifushane kuphela.

Irabha: umkhiqizo uthambile, uyacasula, awukhululekile ezigulini, futhi kulula ukubangela ukuvuvukala kwe-mucous membrane ye-urethra.Kulula futhi ku-calcium, kodwa akubizi futhi ikakhulukazi ngaphandle kwamabhaluni .

I-Silicone: umkhiqizo uthambile, cishe awucasuli, uyavumelana ne-biocompatible futhi awukho umuzwa womzimba wangaphandle ezigulini.I-diameter yangaphakathi ebanzi ye-silicone catheter ifaneleka i-catheterization yokuhlala yesikhathi esimaphakathi nesikhathi eside, engagwema ukungena okuningi, ukunciphisa ukungqubuzana ne-urethra, ukunciphisa ubuhlungu besiguli futhi kunciphise ukuvela kokutheleleka kwe-urinary tract.Nokho, ebusweni ngesikhathi inqubo ukwakha akulula ukugcina bushelelezi.Inezindleko eziphakeme, ikakhulukazi ngaphandle kwamabhaluni.

I-Latex: umkhiqizo uthambile, u-biocompatible futhi unethezekile ezigulini.Inobuso obushelelezi obuphakeme, ukucasuka okuncane kakhulu kanye nenani elifanele, iningi linamabhaluni, alungele ukufakwa kwe-catheterization futhi angashiywa ngesikhathi esifushane.Kodwa ukuthamba okuthambile kwe-latex catheter kwenza kube nzima ukuyifaka ngokushelela esinyeni, futhi kulula ukucwilisa ukuvaleka kwe-calcium futhi kuba nokusabela kwe-cytotoxic.

I-Single-lumen catheter: inesiteshi esisodwa kuphela, ngokuvamile ayinamabhaluni, akulula ukuyilungisa, futhi ingashiywa isikhathi esifushane kuphela.Kudingeka kulungiswe ngamakhasethi uma usebenzisa.

I-Double-lumen catheter: ine-lumen emibili, i-lumen yomjovo kanye ne-outlet ye-liquid, okulula ukuyilungisa, evikelekile futhi akulula ukuyingcolisa.Isetshenziswa kaningi ku-catheterization yangaphakathi.

I-three-lumen catheter: kukhona ilume emithathu yomjovo wamanzi, ilume yedrainage kanye nelume lomjovo wezidakamizwa, ezisetshenziselwa kakhulu ukufakwa kwe-catheterization yesikhashana, i-intravesical drug drip, i-flushing kanye nokukhipha amanzi.

I-catheter ene-lumen enamabhaluni aphindwe kabili: i-catheter ifakwe amabhaluni amabili:ibhaluni elibeka indawo ngaphambili livimba intamo yesinye;Ibhaluni elivalayo libekwe ngemuva ukuze livale i-urethra futhi lenze indawo evalekile ukuze kutholakale ukwelashwa kwezidakamizwa zendawo.I-lumen emibili engaphandle kwebhaluni ivumela ukuchelelwa kwesinye okuqhubekayo.Ibaluleke kakhulu ngokomtholampilo kune-catheter ene-lumen emithathu enamabhaluni aphindwe kabili

Ukusungulwa kwenqubo yokukhiqiza

Ngokuthuthuka okuqhubekayo kobuchwepheshe bokukhiqiza, i-catheter iye yabhekana noshintsho kusukela ekukhiqizeni kwendabuko, ukukhiqizwa kwesimanje, kuya ekukhiqizeni okuzenzakalelayo okugcwele.Kulezi zinsuku, kusetshenziswa imishini ezenzakalelayo nenemba ekukhiqizeni ama-catheter.Ukukhiqiza okuzenzakalelayo akwehlisi nje kuphela izindleko zokukhiqiza futhi kuthuthukisa izinga lobuchwepheshe, kodwa futhi kuthuthukisa ikhwalithi yomkhiqizo, kukhuphule umthamo, futhi kusheshise ukuthuthukiswa kwemboni.

Imishini yokuhlanganisa i-catheter ye-Hengxingli ye-PVC ezenzakalelayo ingakwazi ukuzenzela yonke inqubo yokukhiqiza: izinto zokuphakela ezizenzakalelayo nokukhipha imikhiqizo eqediwe, amathiphu wokushisela i-catheter, ukuhlanganisa izixhumi nokuhlola imikhiqizo eqediwe, ngesilinganiso sesivuno esingu-99%.Ukuhambisana kwayo okuphezulu kuyivumela ukuthi yenze ngendlela oyifisayo osayizi bomkhiqizo nobude ngokwezidingo.Ngaphezu kwalokho, inqubo yokusabalalisa ngobuningi ingenza umkhiqizo ube muhle kakhulu futhi uqine;Ikhanda lokushisela elinemvamisa ephezulu livumela ukwakheka kwamathiphu e-catheter acinene.

Ukuze kuhlangatshezwane nezidingo ezahlukene zokukhiqiza, umshini wokuhlanganisa we-Hengxingli silicone catheter catheter ungahlanganisa ngokunembile amabhaluni futhi usebenzise ithubhu elishwabene ukushisa ukuze ushise futhi ulolonge, ukuze ishubhu libe bushelelezi futhi lithuthukise ngempumelelo ukunethezeka komkhiqizo.Ngaphezu kwalokho, ukufafaza kweglue kunembile futhi kufana, futhi ngemva kokunwetshwa kwebhaluni, kungaqinisekisa ukuthi ukugxila komzimba we-catheter kanye nebhaluni kuyahambisana, okuqinisekisa ngempumelelo ikhwalithi yomkhiqizo futhi kukhuthaze inqubo yokukhiqiza i-catheter ukuze iqhubeke. ngezikhathi.
