Ityhubhu ye-plasi yegazi

Imixholo yegazi elingenanto eqokelela iityhubhu: kule mihla, iityhubhu zegazi zenziwe kakhulu zezaglasi zeglasi. I-PH yeglasi eqhelekileyo yahluke kakhulu, kwaye kunokwenzeka ukuba i-hemolysis inyuke kakhulu. Nangona kunjalo, iityhubhu zovavanyo zeglasi ezenziwe yinkqubo yokuzoba ityhubhu zisasazwe ngemigca emgangathweni, kwaye ubunzulu kunye nobungqingqwa bukhokelela ekuxhotyisweni kweeseli. Xa kuthelekiswa neglasi engathathi hlangothi (iglasi yezamayeza), izibonelelo ziyabonakala. Iglasi engathathi hlangothi ineengenelo zokungathathi cala, izinto ezincitshisiweyo ezincitshisiweyo, ilungiselelo lemolekyuli eliqinileyo, kwaye lingalunganga le-PB2 +, i-GB2 +, iZN2 +, no-Fe2 +. Oku kunokutshintsha iipropathi zantlandlolo zeesampulu zegazi, ke iityhubhu zovavanyo zeglasi kufuneka zitshintshe kwaye zifakwe ngaphambi kokusetyenziswa. Unyango lwangaphakathi lwangaphakathi luphawu, oko kukuthi, ioyile yesilika ichithwe kwi-ether kunye ne-ethanol, kwaye udonga lwe-tube oluhlaza lomiswe okanye lubhakiwe. Kuba ioyile yesilika ngumxube we-intert, akunakwenzeka ukuba nako ukusebenzisana nomchiza weglasi, kodwa unamathela kuphela kudonga lwangaphakathi lwetyhubhu yovavanyo kwaye luyekile ukuzila. Ukongeza, ioyile yesilika inefuthe eliqaqambileyo kwi-orgadic acid radical ye-anticouhlalar engaphambi kokuba i-anticoursul, ukuze amandla okuhamba komgangatho aphulukene ne-regent. Okwangoku, eyona ndlela eyonakeleyo yonyango yi-Colodiation 60 ye-Ireradiation kunye ne-deoed Rinking yamanzi ukuqinisekisa ukugula, ukugungqa, kwaye akukho nto yangaphandle, kwaye ithintele i-hemolysis. Udonga lwangaphakathi lwetyhubhu yokuqokelelwa kwegazi ngaphandle kongezi-songezo luhlanganiswe nge-silicone ukuthintela iiseli zegazi ekunxibeleleni eludongeni kwaye kuthintele iiseli ukuba zaphulwe kwikrisigigififietion. Nangona kunjalo, ukusuka kwimbono yokukhusela kwendalo esingqongileyo, iityhubhu zokuqokelela kwegazi zegazi zenziwe ngeplastiki kwaye zilula kakhulu, kwaye zinokuhamba ngokuthe ngqo, kwaye ziya kuba yinto entle emva kokukhethwa Iityhubhu zegazi vacuum.

Ukuma kwe-Sealant: Umgangatho wokuma okutywina ichaphazela ngokuthe ngqo intsebenzo yengqekembe yegazi i-tube ye-tube yendawo yokuqala yesampulu yegazi. Kucetyiswa ukuba usebenzise irabha ye-butyl endaweni yerabha yendalo. Iifilimu zerabha zerabha zendalo zinoluhlobo olunzulu kwaye luhlobo lwezinto ezinokubangela i-hemolysis. Iifilimu ezininzi ze-organic kunye nezongezo (kubandakanywa ioyile yeparafini, ioyile ye-silicone, izintlukwano, ezikolo, njl njl.). Izinto ezifana ne-heparin zichaphazela ngokukodwa ukungathobeli kwamanzi kwe-heparin eyomileyo ye-hemparin-njenge-shearin-njenge-vaparin kunye nengqubana. Ukongeza, ukungangqinelani komoya kunye nokungafikeleli kwamanzi akuhambelani neemfuno zobugcisa zetyhubhu, ilahleko ye-vacuum ibaluleke kakhulu, kwaye i-vanction yeplagi ibone ukuba iplagi inamathele kakhulu eludongeni. I-butyuber i-braber inesithuba esihle sokutywina, kwaye izinto ezincitshisiweyo zincitshiswa kakhulu, ukuze ityhubhu yokuqokelelwa kwegazi inokugcina vacuum kangangeenyanga ezingama-24 nangaphantsi koxinzelelo olubi lwe-101.3 lwe-KPA. I-vacuum engagungqiyo inceda into yokuqokelela igazi ukuze ihlale iqokelelwe i-galloment ingqokelela yegazi kunye noxinzelelo lwegazi, kunye nempazamo yokuqokelela igazi inokwenzeka ilawulwa ngaphakathi kwe-5%. Umthombo wemposiso ikakhulu kukutshintsha komfanekiso wegazi kunye nempazamo yokusebenza ngengozi, kwaye elinye isandla ngumahluko omncinci kububanzi betyhubhu yovavanyo. Iityhubhu zokuqokelelwa kwegazi zanamhlanje ziyilelwe kakhulu nge-CAPS ye-windows. Umaleko wangaphakathi weplagi yerabha ethanjisiweyo kunye ne-thobricant igqunywe nge-tube ye-tube ye-Tube, eyenza kube lula kakhulu ukuba ivule, kwaye indlela yayo yokuvula inokuthintela igazi ukuba ikhuphe igazi ukuba liphume igazi. Uyilo oluyenziwe i-raibe lweplagi lenza isigqubuthelo lukhuselekile ngakumbi, kwaye inxenye yeConcave ngaphezulu kwesiciko inokuthintela ukunxibelelana neesampulu zegazi kwaye inciphise ungcoliseko lwegazi kubaqhubi. Ukusetyenziswa kwetyhubhu yokuqokelelwa kwegazi kuphawulwa ngombala owamkelwe kwihlabathi jikelele wentloko yentloko, eqaqambileyo kwaye ebambe ngamehlo kwaye kulula ukwahlula-hlula, ukuphepha ukusetyenziswa kweesampulu ezikhutshelweyo kunye nokungangqinelani kweesampulu ezithunyelwe izinto zovavanyo.
