Hauv Suav teb, nws tau hu ua "Qi," lub cim rau kev noj qab haus huv. Hauv tebchaws Iziv tau hu ua "Ankey," lub cim rau txoj sia nyob mus ib txhis. Rau cov neeg Phoenicians, cov lus siv tau sib txuas nrog aphrodite-tus vajtswv poj niam ntawm kev hlub thiab kev zoo nkauj.
Cov neeg ua haujlwm thaum ub tau hais txog tooj liab, cov khoom uas lawv tau lees paub txog kev noj qab haus huv ntau dua 5, O00 xyoo. Thaum inflexas, cov kab mob zoo li E. coli, superbugs zoo li MRSA, lossis txawm tias cov chaw tawv tawv, lawv tuaj yeem nyob tau plaub txog tsib hnub. Tab sis thaum lawv tsaws ntawm tooj liab, thiab tooj liab alloys zoo li tooj dag, lawv pib tuag tsis pub dhau feeb thiab tsis muaj cov xuab moos.
"Peb tau pom cov kab mob tsuas yog tshuab sib nrug," Sebor of Envanum Healthcare ntawm University of Southmepton. "Lawv tsaws rau ntawm tooj liab thiab nws tsuas yog ua rau lawv xav tsis thoob tias hauv Is Nrias teb, cov neeg tau haus tawm ntawm lub khob tooj liab liab rau ntau txhiab. Txawm nyob ntawm Tebchaws Meskas, yog tus tooj liab khiav coj hauv koj cov dej haus. Tooj liab yog lub ntuj, passive, cov khoom siv antimicrobial. Nws tuaj yeem ua rau nws tus kheej-sterilize nws nto yam tsis muaj hluav taws xob lossis tshuaj dawb.
Tooj liab tsoo thaum lub sij hawm trolution ncig raws li cov khoom siv rau cov khoom, conftures, thiab cov tsev. Tooj liab tseem muaj dav siv hauv lub zog tes hauj lwm-lub tooj ua lag luam tooj liab yog, qhov tseeb, loj hlob vim tias cov khoom siv zoo li no. Tab sis cov khoom siv tau raug thawb tawm ntawm ntau lub tsev thov los ntawm nthwv dej ntawm cov khoom tshiab los ntawm xyoo pua 20th. Cov iav plastics, tempered iav, txhuas, thiab hlau stainless yog cov ntaub ntawv ntawm cov khoom siv niaj hnub no rau cov khoom lag luam. Nrig dag qhov rooj qhov rooj qhov rooj thiab tesns tau tawm ntawm cov style ua vajtse cov vaj tse thiab cov tsim qauv xaiv rau sleeker-saib (thiab feem ntau pheej yig dua) cov ntaub ntawv.
Tam sim no keevil ntseeg tias nws yog lub sij hawm coj tooj liab rov qab rau hauv cov chaw pej xeem, thiab tsev kho mob tshwj xeeb. Nyob rau hauv lub ntsej muag ntawm unavoidable yav tom ntej tag nrho ntawm cov thoob ntiaj teb Pandemics, peb yuav tsum tau siv tooj liab hauv kev kho mob, thiab txawm peb lub tsev. Thiab thaum nws lig dhau lawm kom nres cov pab pawg-19, nws tsis tau ntxov dhau los xav txog peb cov nyiaj pandemement.Qhov cov txiaj ntsig ntawm tooj liab, kom muaj txiaj ntsig
Peb yuav tsum tau pom nws los, thiab qhov tseeb, ib tug neeg tau ua.
Xyoo 1983, cov kws tshawb fawb kho mob phyllis J. Kuhn tau sau thawj zaug ntawm kev ploj ntawm tooj liab nws tau pom hauv tsev kho mob. Thaum lub sij hawm kev cob qhia tawm dag zog ntawm Hamot Medical Center hauv Pittsburgh Center hauv Pittsburgh, cov tub ntxhais kawm Swabbed ntau thaj chaw nyob ib ncig ntawm chav tsev kho mob thiab cov chaw tso quav thiab lub qhov rooj. Nws pom tias cov chaw tso quav tau huv ntawm cov microbes, thaum qee qhov kev kho kom zoo nkauj thiab loj hlob ntawm cov phiaj dav dav.
"Sleek thiab ci ntsa iab stainless hlau doorknobs thiab thawb daim hlau saib kev txhawb nqa kom huv rau ntawm lub qhov rooj hauv tsev kho mob. Los ntawm kev sib piv, cov paib thiab thawb daim hlau ntawm tarnished tooj liab zoo li tsis huv thiab paug, "nws sau rau lub sijhawm. "Tab sis txawm tias thaum tarnished, tooj dag-ib qho ntawm 67% tooj liab - txog 88% yas ntawm 88% siv hlau) thiab 12%-tsawg los cuam tshuam kev loj hlob."
Thaum kawg, nws muab nws daim ntawv muab qhwv nrog qhov yooj yim txaus kom txaus xaus rau tag nrho cov kev kho mob kom ua raws. "Yog tias koj lub tsev kho mob raug kho dua tshiab, sim khaws cov qub tooj dag kho vajtse lossis nws tau rov ua dua; Yog tias koj muaj cov khoom siv hlau stainless hlau, ua kom nws raug tua kab niaj hnub, tshwj xeeb hauv thaj chaw tseem ceeb. "
Qeb tom qab, thiab kev lees paub nrog nyiaj los ntawm kev txhim kho tooj liab kev ua haujlwm (ib pab tooj liab ua lag luam), keevil tau thawb Kuhn txoj kev tshawb fawb ntxiv. Ua haujlwm nyob rau hauv nws sim nrog qee cov kev ntshai tshaj plaws hauv ntiaj teb, nws tau pom tias tsis yog ua tus tooj tua hluav taws tsis zoo; Nws kuj tua cov kab mob.
Hauv keevil txoj haujlwm, nws dips lub phaj tooj liab rau haus cawv rau sterilize nws. Tom qab ntawd nws dips nws mus rau acetone kom tau tshem tawm cov roj rho tawm. Tom qab ntawd nws poob me ntsis ntawm pathogen rau saum npoo. Nyob rau hauv lub sijhawm nws tau qhuav. Cov piv txwv tso rau txhua qhov chaw ntawm ob peb feeb mus rau ob peb hnub. Tom qab ntawd nws shakes nws nyob rau hauv ib lub thawv tag nrho ntawm iav hlaws dai thiab kua. Cov hlaws dai txhuam tawm cov kab mob tawm cov kab mob thiab kab mob rau hauv cov kua, thiab cov kua tuaj yeem raug kuaj kom paub txog lawv lub xub ntiag. Hauv lwm qhov xwm txheej, nws tau tsim cov txheej txheem me me uas tso cai rau nws saib-thiab sau-ib kab ntawm tooj liab lub sijhawm nws hits saum npoo.
Cov nyhuv zoo li khawv koob, nws hais tias, tab sis txij ntawm no, qhov tshwm sim ntawm kev ua si yog cov kev paub zoo. Thaum tus kab mob lossis kab mob ntaus lub phaj, nws yog dej nyab nrog tooj nkoog ions. Cov kabmob uas mob hlwb thiab cov kab mob xws li cov mos txwv. Tus tooj liab tsis yog tua cov pathogens no; Nws rhuav tshem lawv, txoj cai mus rau nucleic acids, lossis kev ua me nyuam qhuav, sab hauv.
"Tsis muaj ib lub caij nyoog ntawm kev hloov [lossis kev hloov pauv] vim tias txhua tus genes raug rhuav tshem," hais keevil. "Qhov ntawd yog ib qho ntawm cov txiaj ntsig tiag tiag ntawm tooj liab." Hauv lwm lo lus, siv tooj liab tsis tuaj nrog txoj kev pheej hmoo, hais tias, dhau-antcribing tshuaj tua kab mob. Nws tsuas yog lub tswv yim zoo.
Hauv kev sim tiag tiag hauv ntiaj teb, tooj liab ua pov thawj seb tus neeg tshawb nrhiav hauv tsev kho mob muaj dab tsi, thiab txawm tias cov neeg tshawb xyuas hauv tsev kho mob, thiab tseem muaj lub hauv paus kev cai lij choj los ntawm 58%. Ib qho kev kawm zoo sib xws hauv xyoo 2016 sab hauv cov kws kho mob plab me me, uas tau teeb tsa ib qho kev txo tus kab mob zoo sib xws.
Tab sis dab tsi txog kev siv nyiaj? Tooj liab ib txwm kim dua li yas los yog txhuas, thiab feem ntau yog ib qho kev xaiv sib txawv ntawm cov hlau. Tab sis muab cov kab mob uas pw hauv tsev kho mob yog them nyiaj rau cov neeg kho mob ntau npaum li $ 90,000 tus neeg tooj liab nce nqi yog qhov tsis lees paub los ntawm kev sib piv.
Keevil, uas tsis tau txais nyiaj los ntawm tooj liab kev lag luam, ntseeg lub luag haujlwm ntog los xaiv tooj liab hauv cov phiaj xwm tshiab. Tooj liab yog thawj (thiab kom deb li deb nws yog lub xeem) antimicrobial hlau nto pom zoo los ntawm EPA. (Cov tuam txhab hauv kev lag luam cov nyiaj tau sim thiab ua tsis tiav nws yog antimicrobial, uas tiag tau coj mus rau ib qho epra zoo.) Leelots alloys nrog EPA rau hnub tim. Nws hais tias "Peb tau qhia tooj liab-Xib Npib tsuas yog ua kom zoo li tooj dag ntawm kev tua cov kab mob thiab kab mob," nws hais. Thiab tooj liab Nickel tsis tas yuav zoo li lub suab nrov qub; Nws yog indistinguishable los ntawm stainless hlau.
Raws li rau tus so ntawm lub ntiaj teb cov vaj tse uas tsis tau hloov kho tawm ntawm lub tsev tooj liab qub, keevil muaj ib daim ntawm cov lus ntuas: "Tsis txhob tshem lawv, txhua yam koj ua. Cov no yog qhov zoo tshaj plaws uas koj tau txais. "
