Catheter ndi makina azachipatala a Gulu II, chubu chomwe chimayikidwa mu chikhodzodzo ndi mkodzo kuti athetse mkodzo, makamaka omwe amagwiritsidwa ntchito kwa odwala omwe ali ndi vuto la mkodzo kapena chikhodzodzo, kusadziletsa, odwala omwe amafunikira kupuma kwa nthawi yayitali kapena kukakamizidwa, ndi odwala. mu nthawi ya perioperative ya opaleshoni.Ma catheter nthawi zambiri amagawidwa m'mitundu 13 yokhala ndi mawonekedwe kuyambira 6F mpaka 30F molingana ndi circumference ya m'mimba mwake, ndipo mitundu inayi ya 12F, 14F, 16F ndi 18F imagwiritsidwa ntchito kwa akulu.

Zinthu za catheter

Ma catheter amapangidwa makamaka ndi polyvinyl chloride, silikoni, latex, etc. Ma catheter opangidwa ndi zinthu zosiyanasiyana amakhala ndi mawonekedwe osiyanasiyana:

Polyvinyl chloride (PVC): mankhwalawa ndi ovuta, amakwiyitsa kwambiri, amamva thupi lachilendo komanso otsika mtengo, Mankhwalawa amakhala opanda mabuloni komanso osagwirizana ndi biocompatible, amakonda kumamatira, ndipo amatha kusiyidwa kwakanthawi kochepa.

Mphira: mankhwalawo ndi ofewa, okwiyitsa, osamva bwino kwa odwala, komanso osavuta kuyambitsa kutupa kwa mucous nembanemba ya mkodzo.Ndiwosavuta ku calcium, koma yotsika mtengo komanso makamaka yopanda mabuloni.

Silicone: mankhwala ndi ofewa, pafupifupi osakwiyitsa, biocompatible ndipo palibe thupi lachilendo kumverera kwa odwala.Kutalikirana kwamkati kwa catheter ya silikoni ndi koyenera kwa catheterization yapakatikati komanso yayitali, yomwe ingapewe ma intubation angapo, kuchepetsa kukangana ndi mkodzo, kuchepetsa ululu wa wodwalayo ndikuchepetsa kupezeka kwa matenda a mkodzo.Komabe, pamwamba pa kupanga ndondomeko si kophweka kusunga yosalala.Ili ndi mtengo wokwera, makamaka wopanda mabuloni.

Latex: mankhwala ndi ofewa, biocompatible ndi omasuka kwa odwala.Ili ndi malo osalala kwambiri, kupsa mtima pang'ono komanso mtengo woyenera, ambiri okhala ndi ma baluni, omwe ndi abwino kuyika catheterization ndipo amatha kusiyidwa kwakanthawi kochepa.Koma kufewa kwa catheter ya latex kumapangitsa kuti zikhale zovuta kulowetsa bwino m'chikhodzodzo, ndipo zimakhala zosavuta kumira kutsekeka kwa calcium ndipo zimakhala ndi cytotoxic reaction.

Catheter ya lumen imodzi: ili ndi njira imodzi yokha, nthawi zambiri imakhala yopanda mabaluni, sizovuta kukonza, ndipo imatha kusiyidwa kwakanthawi kochepa.Iyenera kukhazikitsidwa ndi matepi mukamagwiritsa ntchito.

Catheter ya lumen iwiri: ili ndi lumen iwiri, lumen ya jekeseni ndi kutuluka kwamadzimadzi, zomwe zimakhala zosavuta kukonza, zotetezeka komanso zosavuta kuipitsa.Amagwiritsidwa ntchito kwambiri pakupanga catheterization.

Catheter ya lumen itatu: pali lumen ya jakisoni wamadzi atatu, lumen ya madzi ndi lumen ya jakisoni wamankhwala, zomwe zimagwiritsidwa ntchito makamaka pakuchepetsa kwa nthawi yayitali, kudontha kwa mankhwala, kutulutsa ndi kutulutsa.

Catheter ya lumen inayi yokhala ndi ma baluni awiri: catheter ili ndi mabaluni awiri: baluni yoyika kutsogolo imatchinga khosi lachikhodzodzo;Baluni yotseka imayikidwa kumbuyo kuti itseke mtsempha wa mkodzo ndikupanga malo otsekeka kuti athe kulandira chithandizo chamankhwala.Ma lumen awiri omwe ali kunja kwa baluni amalola kuthirira kwa chikhodzodzo mosalekeza.Ndiwofunika kwambiri pachipatala kuposa catheter ya lumen itatu yokhala ndi mabuloni awiri

Kusintha kwa njira yopangira

Ndikukula kosalekeza kwaukadaulo wopanga, catheter yakumana ndi kusintha kuchokera pakupanga kwachikhalidwe, kupanga kwamakono, kupanga zodziwikiratu.Masiku ano, zida zodziwikiratu komanso zida zolondola zimagwiritsidwa ntchito popanga ma catheter.Kupanga zokha sikungochepetsa mtengo wopangira ndikukulitsa luso laukadaulo, komanso kumapangitsa kuti zinthu ziziyenda bwino, zimawonjezera mphamvu, ndikufulumizitsa chitukuko chamakampani.

Hengxingli zodziwikiratu PVC catheter msonkhano zida akhoza automate lonse kupanga: zipangizo kudyetsa basi ndi kutulutsa zomalizidwa, nsonga kuwotcherera catheter, kusonkhanitsa zolumikizira ndi kuyesa mankhwala yomalizidwa, ndi 99% mlingo zokolola.Kugwirizana kwake kwakukulu kumalola kuti isinthe kukula kwake ndi kutalika kwake malinga ndi zofuna.Kuphatikiza apo, njira zoperekera zochulukira zimatha kupanga chinthucho kukhala chokongola komanso champhamvu;Mutu wowotcherera wothamanga kwambiri umalola kupanga maupangiri owoneka bwino a catheter.

Kukwaniritsa zofunika zosiyanasiyana kupanga, Hengxingli silikoni katheta baluni msonkhano makina akhoza molondola kusonkhanitsa zibaluni ndi ntchito kutentha shrinkable chubu kutentha ndi mawonekedwe, kotero kuti potsetsereka chubu ndi bwino ndi bwino kusintha chitonthozo cha mankhwala.Kuphatikiza apo, kupopera kwa guluu ndikolondola komanso kofanana, ndipo pambuyo pakukulitsa kwa baluni, kumatha kuwonetsetsa kuti thupi la catheter ndi baluni limakhala lokhazikika, zomwe zimatsimikizira kuti chinthucho chili bwino komanso chimalimbikitsa kupanga catheter kuti ipitirire. ndi nthawi.
