Nrog rau txoj kev loj hlob ntawm tib neeg thiab tib neeg txoj kev xav txog kev noj qab haus huv, qhov kev thov hauv kev kho mob kuj nce ntxiv. Cov koob txhaj tshuaj yog ib qho ntawm cov cuab yeej tseem ceeb hauv kev kho mob thiab tau siv dav hauv tsev kho mob, tsev kho mob thiab tsev neeg tshuaj. Lub hauv paus tseem ceeb ntawm cov koob txhaj tshuaj, lub piston foob, yog lub hauv paus rau kev txhawb nqa tag nrho cov syringe ua haujlwm. Kab lus no yuav tham txog kev ua tau zoo, cov ntaub ntawv thiab qhov tseem ceeb ntawm kev kho mob syringe piston seals los ntawm ntau yam, aiming qhia cov ntaub ntawv zoo thiab qhia cov neeg nyeem kom nkag siab tob thiab nkag siab txog qhov "tsis paub" ntaus ntawv no.
Ua ntej, cia peb saib seb cov piston seals coj li cas hauv lub koob txhaj tshuaj. Lub syringe yog ib yam khoom siv kho mob uas txhaj cov kua rau hauv tib neeg lub cev los ntawm kev thawb lub piston, thiab cov nyhuv sealing ntawm lub piston foob ncaj qha cuam tshuam rau kev siv cov syringe. Nyob rau hauv ib txwm siv, lub piston foob yuav tsum tau muab cov tshuaj thaum lub sij hawm kom ntseeg tau tias lub syringe ua hauj lwm nrog ib tug me ntsis quab yuam kom tsis txhob mob ntau dhau los yog raug mob rau tus neeg mob. Yog li ntawd, piston seals yuav tsum tsis tsuas yog muaj cov qib siab nruj, tab sis kuj muaj cov elasticity txaus thiab hardness kom ntseeg tau tias kev ua haujlwm zoo ntawm cov koob txhaj tshuaj.
Yog li, dab tsi yog cov khoom ntawm lub piston foob? Feem ntau hais lus, kev kho mob syringe piston seals yog ua los ntawm cov khoom siv roj hmab, xws li roj hmab butyl, silicone roj hmab, thiab lwm yam. Cov khoom siv roj hmab no muaj kev sib khi zoo heev thiab kev tiv thaiv corrosion, thiab tuaj yeem hloov mus rau qhov sib txawv ntawm qhov kub thiab txias, yog li xyuas kom meej tias cov syringe tuaj yeem ua haujlwm. feem ntau nyob rau hauv ib puag ncig siv sib txawv. Tau kawg, kuj tseem muaj cov ntaub ntawv tshiab xws li thermoplastic elastomers (TPEs), uas muaj qhov zoo ntawm kev tsim tau zoo, nrawm nrawm thiab cov nqi tsim khoom tsawg.
Thaum kawg, cia peb tham txog qhov tseem ceeb ntawm piston seals rau cov koob tshuaj kho mob. Hauv kev kho mob, cov koob txhaj tshuaj yog cov cuab yeej tseem ceeb rau cov kws kho mob ua cov tshuaj txhaj tshuaj, thiab tus yuam sij rau lawv qhov zoo yog qhov zoo ntawm cov ntsaws ruaj ruaj. Yog hais tias lub piston foob tsis ua raws li qhov yuav tsum tau ua, nws yuav ua rau lub syringe tsis ua haujlwm zoo, lossis txawm tias xau thaum lub sijhawm txhaj tshuaj lossis ua rau muaj kev pheej hmoo ntawm kev sib kis. Yog li ntawd, kev kho mob zoo syringe piston foob yog qhov tseem ceeb los tiv thaiv lub neej kev nyab xeeb ntawm cov neeg mob.
Nyob rau hauv luv luv, txawm hais tias lub piston foob ntawm kev kho mob syringes yog ib tug tsis tu ncua tivthaiv nyob rau hauv syringes, nws qhov tseem ceeb tsis tau underestimated. Los ntawm kev nkag siab thiab kev paub txog kev kho mob syringe piston seals, peb tuaj yeem nkag siab zoo dua txog kev siv tshuab thev naus laus zis thiab kev vam meej hauv cov tshuaj, thiab tseem muab kev lav zoo rau peb tus kheej kev noj qab haus huv. Nws cia siab tias cov neeg nyeem tuaj yeem nkag siab qhov tseem ceeb ntawm cov koob txhaj tshuaj thaum nkag siab thiab siv lawv, ua tib zoo saib xyuas qhov zoo thiab kev nyab xeeb ntawm cov khoom, thiab sib koom ua ke txhawb kev txhim kho kev noj qab haus huv ntawm kev kho mob.
