I-catheters engenangqondo iyithuluzi lezokwelapha elilahlwayo; i-latex engenalutho, amacilisi, ama-polyvinylchloride amashubhu of design, ubude nobubanzi obuhlukahlukene. Isetshenziswe ku-urology ngenhloso yokwelashwa nokuxilonga.
Izinhloso zokusebenzisa ama-catheter we-urological
Ama-catheter angenangqondo afakwa kwisigqila ngokusebenzisa i- urethra , futhi uma kwenzeka isithiyo sayo - ngokusebenzisa i-fratula e-suprapubic e-urinary. Ukusetshenziswa kwabo kudingekile ngezifo ezihlukahlukene ze-urological, okuholela ekutheni akakwazi ukukhipha isirabhu yedwa. Ngesizo samakhemikhali angenabuhlungu, inqubo yokwenza izidakamizwa yenziwa (ukukhipha isisindo). Ngaphezu kwalokho, izinhlobo ezihlukahlukene zezikebhe ezingasetshenzisiwe zisetshenziselwa: ukukhipha isirabhu, ugeze, ujobe izinto ezikwelapha, njll.
Izinhlobo zama-catheters angenangqondo
Imakethe yesimanje yezokwelapha isinikeza izinhlobonhlobo zamakhemikhali ezinama-cavitary, ikakhulukazi:
- ama-catheters of ububanzi obuhlukene nobude;
- amakhemikhali edizayini ehlukene, inombolo ehlukene yokuhamba;
- Ama-catheter aqinile (metallic) futhi athambile (i-rubber);
- amakhemikhali okwenza i-catheterization yesikhathi esifushane nesikhathi eside;
- amakhemikhali wezingane kanye nabantu abadala;
- Catheters abesilisa nabesifazane abanobuhlungu.
Uhlobo oludingekayo lwe-catheter ye-urological luhlotshaniswa nokuxilongwa, ubulili, ubudala, kanye nezici zesifo se-urethra yesiguli.
Izinhlobo ezivame ukusetshenziselwa izinhlanzi ezinokuhlukumezeka yizi:
- Ama-catheters ase-Urolic kaFoley . Idizayinelwe ukuphazamisa isikhathi eside: kusukela ezinsukwini ezingu-7 (i-latex) kuya ku-1 inyanga (abicah). Kukhona indlela emibili nendlela ezintathu. Esinye isifo sibonisa umchamo, owesibili ukuphathwa kwezidakamizwa, okwesithathu (uma i-catheter iyindlela emithathu) isetshenziselwa ukugxilisa imithi . Wonke ama-catheters angenalutho angenalutho ekupheleni kwawo okude, okuyinto emva kokugcwalisa isambiso igcwele ngamanzi oyinyumba, ukuze igcinwe ngokuqinile esiceleni.
- Amakhemikhali abesilisa nabesifazane abanobugebengu beNelaton . Yenzelwe ukuchithwa kwesikhashana esifushane. I-polyvinyl chloride yezokwelapha, okuvela kuzo izintambo ze-Nelaton, iyancipha ngaphansi kwethonya lokushisa komzimba, okuvumela ukuphathwa okulula nokubuhlungu. Amakhemikhali abesilisa nabesifazane balezi zinhlobo ahlukene ngobude, akhiqizwa ngo-20 no-40 cm, abesifazane nabesilisa, ngokulandelana.
- Amakhemikhali e-Timan (i-rabber) ne-Mercier (ipulasitiki) . Unomklamo ofanayo: ukuphela kwe-distal ekugcineni kanye ne-scallop ekupheleni kwangaphandle, okubonisa ukuqondiswa kwe-bend. I-catheter ye-Mercier iyancishiselwa emanzini ashisayo ngaphambi kokusetshenziswa, ithola ukuqina futhi ikwazi ukuphinda igoba le-urethra ngangokunokwenzeka.
- I-catheters enobuchopho obhekene ne-pescera . Isetshenziswa ezimweni lapho ukugcoba nge-urethra akunakwenziwa. Zitholwa ngokusebenzisa i-suprapubic fistula yomchamo (umsele wangaphakathi emdongeni wangaphakathi kwesisu).
- Amathanga angama-metallic abesilisa nabesifazane abanobuchopho.
Zonke izinhlayiya ezihlukumezayo zihlukahluka ngaphakathi nangaphandle, ngoba ububanzi obunye buhambisana nenombolo ehambelanayo (caliber), kanti ezinye izinhlobo, ikakhulukazi ama-catheter kaNelaton, nazo zinemibala ehlukene yembala. Ukulinganisa kuboniswa ekugcineni kwe-catheter.
Kuphi ukuthenga i-catheter ye-urological?
I-catheter enobuchopho ingathengwa cishe noma yiliphi ikhemisi. Uma uthenga, ungakhohlwa ukuthi ucacise uhlobo lwesikebhe nenombolo yalo (lolu lwazi luzokwaziswa udokotela). Futhi ungathenga ngekhemisi e-intanethi noma esitolo esithile se-intanethi. Ukuzuzwa okungenasisekelo kwamakhemikhali ahlukumezayo ukukwazi ukukwazi ukukwenza.
