A Thaum tshav kub kub Moisture Exchanger (HME)yog ib txoj hauv kev los muab cov av noo rau cov neeg laus tracheostomy. Ua kom txoj hauv kev ua pa ntub yog qhov tseem ceeb vim nws pab cov kua nplaum nyias nyias kom lawv tuaj yeem hnoos tawm. Lwm txoj hauv kev los muab cov dej noo rau hauv txoj hlab pa yuav tsum tau siv thaum HME tsis nyob hauv qhov chaw.
Cheebtsam ntawmHEM lim
Lub Cheebtsam ntawm HME cov ntxaij lim dej tau ua tib zoo tsim kom ntseeg tau tias kev ua haujlwm zoo. Feem ntau, cov lim dej no muaj cov vaj tsev nyob, hygroscopic media, thiab cov kab mob / kab mob lim txheej. Lub tsev yog tsim los kom ruaj ntseg cov lim dej hauv tus neeg mobua pa Circuit Court. Hygroscopic media feem ntau yog tsim los ntawm cov khoom siv hydrophobic uas ua tau zoo thiab khaws cov dej ntws tawm. Nyob rau tib lub sijhawm, cov kab mob / kab mob lim txheej ua raws li qhov thaiv, tiv thaiv kev kis kab mob thiab cov kab mob.
Cov yam ntxwv ntawm HME Lim:
HME lim yog siv rau ntawm cov neeg mob ua pa circuits kom tsis txhob muaj kev sib kis.
Tsim nyog rau cov neeg mob ua pa tawm nrog lub raj tracheostomy.
Siv tau pom thaj tsam: 27.3cm3
Luer Chaw nres nkoj rau cov qauv roj yooj yim nrog lub hau tethered kom tshem tawm qhov kev pheej hmoo ntawm qhov tsis raug.
Round ergonomic zoo uas tsis muaj cov npoo ntse txo cov cim siab.
Compact tsim txo qhov hnyav ntawm Circuit Court.
Tsawg tsis kam mus rau ntws txo ua haujlwm ntawm kev ua pa
Feem ntau muaj ib txheej ntawm cov npuas dej los yog daim ntawv kos nrog hydroscopic ntsev xws li calcium chloride
Cov kab mob thiab kab mob lim dej zoo tshaj plaws muaj kev pom zoo ntawm> 99.9%
HME nrog humidification efficiency> 30mg.H2O / L
Txuas mus rau tus qauv 15mm connector ntawm lub raj endotracheal
Mechanism ntawm cua sov thiab humidification
Muaj ib txheej ntawm cov npuas dej los yog ntawv embedded nrog hygroscopic ntsev xws li calcium chloride
Cov roj uas tsis tas yuav txias thaum nws hla daim nyias nyias, ua rau muaj qhov sib xyaw ua ke thiab tso tawm ntawm huab cua enthalpy ntawm vaporisation mus rau HME txheej.
ntawm kev tshoov siab absorbed cua sov evaporates lub condensate thiab warms cov roj, hygroscopic ntsev tso dej molecules thaum lub vapor siab yog tsawg.
Ua kom sov thiab humidification yog li tswj hwm los ntawm cov dej noo ntawm cov roj uas tas sij hawm thiab tus neeg mob qhov kub thiab txias.
Ib txheej lim kuj tseem muaj, xws li electrostatically them los yog pleated hydrophobic txheej, tom kawg pab rov qab noo noo rau cov pa thaum condensation thiab evaporation tshwm sim ntawm cov pleats.
Mechanism ntawm filtration
Pom tau tiav rau qhov loj dua (> 0.3 µm) los ntawm inertial impaction thiab interception
Cov me me (<0.3 µm) raug ntes los ntawm Brownian diffusion
Kev siv HME Lim
Lawv tau siv dav hauv tsev kho mob, chaw kho mob, thiab chaw kho mob hauv tsev. Cov ntxaij lim dej no feem ntau muab tso rau hauv lub tshuab ua pa, cov tshuaj loog ua pa, thiab cov hlab tracheostomy. Lawv versatility thiab compatibility nrog ntau yam khoom siv ua pa ua rau lawv yog ib feem tseem ceeb ntawm kev saib xyuas ua pa.
Raws li ib tug ua lag luam thiab manufacturers ntawmcov khoom siv kho mob, Shanghai Teamstand Corporation tau cog lus los muab cov lim dej HME zoo uas ua tau raws li cov kev cai nruj ntawm cov kws kho mob. Lawv cov khoom tsim los ntawm kev tsom mus rau cov neeg mob kev nplij siab, kev kho mob zoo thiab kev tiv thaiv kab mob, ua rau lawv muaj kev ntseeg siab rau cov chaw kho mob thoob ntiaj teb.
Peb muab kev xaiv dav thiab dav ntawm HMEFs nrog ntau yam kev ua tau zoo, qhov ntau thiab tsawg thiab cov duab kom ntseeg tau tias cov neeg siv khoom xaiv ntau tshaj plaws thaum ua tau raws li txhua qhov kev kho mob.
