Micro Capillary Tube

Mob taw tes

Hauv kev kuaj mob microfluidic, neuro- aspiration, ib leeg - siv endoscopes, thiab precision dosing systems, engineers tas li ntaus tib phab ntsa: cov dej txoj kev me me dhau rau cov qauv tubing thiab xav tau ntau dhau rau cov khoom siv polymer capillaries. Polymer microbore tubing swells nrog cov kuab tshuaj, absorbs reagents, thiab poob ID kam rau ua tom qab autoclaving. Cov iav capillaries tawg thaum thauj khoom thiab tsis tuaj yeem sib sau ua ke rau hauv cov khoom siv hlau. Plain drawn hlau capillary tubing yog qhov ruaj khov, tab sis nws yog ib qho nyuaj heev los taug qab lub cev los yog tsis muaj zog heev los ua cov khoom siv kho tshuab.

Rau IVD thiab taw tes- ntawm- cov cuab yeej saib xyuas, 0.01 hli ID hloov pauv tuaj yeem hloov pauv tau los ntawm ob npaug - tus lej feem pua ​​vim tias ntws ntsuas nrog plaub lub zog ntawm lub vojvoog. Hauv cov khoom siv cuam tshuam, ib qho capillary uas kinks ntawm qhov kawg ntawm qhov kawg nres ua cov kua dej thiab dhau los ua qhov txhaws. Cov pab pawg xaus ua ke ntau lub raj, ntxiv cov pob qij txha, ua kom cov ntim tuag, thiab tsim kom muaj txoj hauv kev xau. Qhov mob tsis yog "peb xav tau ib lub raj me me" -nws yog "peb xav tau ib lub raj me me uas kuj coj tus yam ntxwv raws li txoj kev xav tau."

Txoj Cai

Lub micro capillary raj yog nyias- phab ntsa hlau lumen qhov twg lub qhov nqa cov kua dej thiab phab ntsa nqa mechanics. Pib los ntawm hypodermic- qib Tshuag xws li 304, 316L, 17-7PH, Nitinol, los yog L605, lub raj yog txias- rub kom nruj OD / ID, ces precision laser-txiav nrog qhov tsawg kawg nkaus kerf ntawm 0.012 hli. Vim hais tias qhov kev txiav khiav raws lub raj, cov kws tsim khoom tuaj yeem muab cov kev coj ua ntawm cov neeg kho tshuab los ntawm qhov sib thooj mus rau qhov chaw: tsis txiav ze rau qhov kawg rau kev thawb thiab lub zog, txiav qhov kawg rau kev taug qab thiab ua raws.

Cov kua dej ua raws li Hagen-Poiseuille tus cwj pwm:

Q = π ΔP r⁴ / 8 η L

Yog li kev tswj tus ID tseem ceeb dua li kev xaiv cov khoom siv. Cov neeg kho tshuab sab ua raws kab teeb-thiab-plhaub mechanics: tshem tawm cov khoom siv phab ntsa tsim flexure hinges; tawm hauv choj khaws cia axial load txoj kev. Lub laser- txiav micro capillary yog li tsis yog "pib." Nws yog ib co-tsim kua dej conductor thiab hloov tau lub cev pob txha.

Nrog txoj kab uas hla ntawm Ø0.20 hli mus rau 20 hli, tib qhov kev tsim cov logic npog ultra-micro diagnostic lumens thiab loj dua cov shafts. Lub 0.012 hli kerf cia cov neeg tsim khoom tso micro- qhov chaw, sab vents, thiab 柔性 zones yam tsis tau rhuav tshem cov phab ntsa nyias.

Kev faib khoom siv

• Kos micro capillary: 304/316L, tsis muaj kev txiav, ruaj ID, siv nyob rau hauv IVD, kuaj kuaj, thiab reagent thauj.
• Sab -slot micro capillary: 316L nrog laser sab qhov rais rau qhov tso pa tawm, ua piv txwv, los yog npuas tso tawm.
• Kauv micro capillary: Nitinol txuas ntxiv lossis cuam tshuam kauv rau tortuous nkag nrog cov kua dej.
• Radial micro capillary: radial txiav tsim ib lub steerable lossis articulating tip thaum ua kom lub lumen qhib.
• Bespoke micro capillary: cov neeg siv khoom 2D / 3D kos duab tsav tsheb, ntau- thaj chaw nruj, kev sib txuas cov cim kev sib txuas, dual lumen mimicry.

Cov lus qhia tswv yim

Txhais ua ntej: kua viscosity, siab, ntim, thiab tso cai tuag ntim.

Xaiv cov khoom siv los ntawm ib puag ncig: 316L rau corrosive kua, Nitinol rau tortuous navigation, 17-7PH rau cyclic flex, L605 rau siab radial load.

Khaws kev sib txuas xaus tsis raug txiav; muab cov yam ntxwv laser nkaus xwb qhov twg cov tshuab lossis cov kua dej yuav tsum hloov.

Electropolish ID kom qis Ra kom txo tau cov qauv nqa mus thiab ua raws li txoj cai.

Tus qauv kink radius, torque poob, thiab siab poob ua ke-tsis cais.

Yuav tsum tau ISO 9001: 2015 thiab ISO 13485 cov ntaub ntawv, cua sov-tus lej traceability, thiab thawj- tshuaj xyuas kab lus.

Kev paub tiag - ntiaj teb

Ib qho IVD OEM hloov polymer microbore tubing nrog electropolished 316L micro capillary. Carryover poob qis thiab CV zoo dua vim tias cov hlau lumen tsis o lossis nqus cov xim. Ib qho kev pabcuam neuro-kev xav tau pib siv cov kauv nruam Nitinol capillary; nyob rau hauv lub tshuab nqus tsev ncej "accordioned." Hloov mus rau kev cuam tshuam kauv- cov khoom siv txuas txhua 1–2 hli- rov qab axial txhav thaum khaws cov kev taug mus deb. Zaj lus qhia: nyob rau hauv micro capillary tsim, yoog raws yam tsis muaj kev txwv axial yog hom tsis ua haujlwm, tsis yog qhov tshwj xeeb.

Xaus

Micro capillary tubing yog qhov twg fluidics ntsib mechanical engineering. Lub raj tsis yog ib tug passive conduit lawm; nws yog ib tug programmed qauv. Leej twg tswj tus ID kam rau ua, phab ntsa uniformity, txiav gradient, thiab nto tiav tswj cov cuab yeej ua haujlwm.

Outlook & cov lus pom zoo

Cia siab tias yuav muaj kev loj hlob ntawm cov khoom siv kuaj mob, cov khoom nruab nrog- ntawm-chip, micro-robots, thiab cov khoom siv endoscopes pov tseg. Cov neeg yuav khoom yuav tsum tsis txhob qhia tsuas yog "OD × ntev." Cov lus qhia tshwj xeeb yuav tsum suav nrog ID kam rau ua, Ra, qhov ntim tuag, kink vojvoog, torque lag, thiab txiav - daim duab qhia chaw. Cov neeg muag khoom yuav tsum muab cov qauv ntws, khoov- cov ntaub ntawv voj voog, thiab cov ntaub ntawv pov thawj / cov pov thawj tsis zoo, tsis yog lub raj duab xwb.
