Cov khoom siv tu cev kho mob yog cov khoom siv tshwj xeeb uas siv rau hauv cov txheej txheem kho mob thiab kev sib cuag ncaj qha lossis tsis ncaj rau tib neeg cov ntaub so ntswg. Yog li ntawd, rau kev kho mob huv si cov ntaub ntawv polymer, tshwj xeeb tshaj yog implantable kho mob polymer cov ntaub ntawv, lawv yuav tsum tau raws li cov khoom ntawm non-toxicity, tshuaj inertness, histocompatibility, ntshav compatibility, tsis kam mus rau lom aging, sterilizability, non-carcinogenicity, thiab yooj yim ntawm kev ua, nyob rau hauv kev txiav txim. kom muaj kev nyab xeeb ntawm cov khoom siv rau tib neeg lub cev.
PA cov ntaub ntawv muaj cov qauv amide zoo ib yam nrog tib neeg lub cev tivthaiv cov protein macromolecules, muaj biocompatibility zoo, thiab tsis yooj yim rau cov hlwb ntawm cov kab mob muaj sia tsim cov cim stimulation.
Tsis tas li ntawd, nws muaj tshuaj lom neeg ruaj khov thiab tswj tau cov khoom siv kho tshuab, thiab lwm yam, tib lub sijhawm, cov hlwb tuaj yeem adsorbed rau saum npoo ntawm PA cov ntaub ntawv. Tag nrho cov khoom tshwj xeeb no ua rau PA cov ntaub ntawv kho mob thiab kev noj qab haus huv, tshwj xeeb tshaj yog cog cov ntaub ntawv PA, ua lub luag haujlwm zoo hauv kev txo cov huab hwm coj, hloov cov khoom siv kho tshuab, thiab tshwj xeeb tshaj yog nyob rau hauv kev tsim kom muaj kev sib koom ua ke ntawm cov khoom siv PA thiab tib neeg lub cev.
Vim nws lub zog zoo heev, kev ua haujlwm siab thiab corrosion kuj, thiab biocompatibility zoo, PA yog dav siv los ua cov catheter kho mob thiab lwm yam khoom siv kho mob. Kev kho mob catheters yog mos, hollow hlab uas tau muab tso rau hauv lub cev los pab nyob rau hauv cov zis tso zis los yog siv raws li cov lus qhia rau ntau yam kev siv nyob rau hauv kev kuaj mob thiab kev kho mob ntawm lub plawv thiab gastrointestinal disorders.PA kho mob catheters kuj yog siv nyob rau hauv cov hlab ntsha drips thiab yuav ua tau. npaj los ntawm PA6, PA66, PA11 thiab PA12.
Raws li cov yam ntxwv ntawm PA cov ntaub ntawv, nrog rau kev kho mob thiab kev tu cev,BAOD Extrusiontau qhia haumextrusion tsimtom qab kev soj ntsuam tas li thiab kev tshawb fawb. Ua tib zoo xav txog qhov tseeb ntawm kev kho mob catheters thiab cov kev xav tau ntawm kev ua haujlwm siab, nws txo qis tus nqi ntawm cov khoom pov tseg thiab tus nqi ntawm cov khoom puas. Los ntawm qhov tsis siv neeg yob hloov khoom siv thiab tsis siv neeg txiav thiab sau, thiab lwm yam, nws txuag tau tus nqi zog thiab ua rau kev lag luam tau txais txiaj ntsig zoo tshaj plaws.
