Kushandiswa kwePortable Medical Oxygen Concentrators muVarwere 'Home Oxygen Therapy
Inotakurika yeokisijeni concentrators yave yakakosha pakupa kurapa kweokisijeni kumba kune varwere vane huwandu hwehurwere hwekufema, kusanganisira COVID-19, chisingaperi chinovhara pulmonary chirwere, chisingaperi bronchitis, uye mabayo.Midziyo iyi inoshanda basa rakakosha rekupa mishonga-giredhi oxygenkuderedza matambudziko ane chekuita ne hypoxemia uye kuwedzera basa rekufema revarwere.
Kuzadzisa zvinodiwaoxygen therapy, kunyanya mumamiriro epamba,inotakurika yekurapa oxygen concentratorskunyanya shandisa tekinoroji yekumanikidza swing adsorption.Iyi tekinoroji inotsamira pane nitrogen-selective adsorbents kuti iburitse okisijeni kubva mumhepo yakadzika, kuve nechokwadi chekuwana kwakasimbaokisijeni yekurapa.Sezvineiwo, World Health Organisation inotaura kuti giredhi reokisijeni yekurapa inofanirwa kuve neokisijeni iri pakati pe90% ne96% V/V, ine yasara nitrogen neargon.Maererano nezviyero izvi, zvakajairwa adsorption-based portable medical oxygen concentrators inowanzopa oxygen concentrations kubva ku90% kusvika 93% pamitengo yekuyerera kazhinji iri pasi pe10 L/min.
Mukushanda kwe-adsorption-based portable medical oxygen concentrators, iyo adsorbent inopinda nguva nenguva yekuvandudzwa kuti irambe ichiita kugadzirwa kweokisijeni.Kuenderera mberi kweokisijeni kunofambiswa kuburikidza nemazano akadai sekuunganidza chigadzirwa okisijeni muchikamu chekuvhiya nekuchipa pamwero unowirirana nekufamba kwenguva kana kushandisa mavhisi emubhedha akawanda.Iyo Skarstrom-type pressure swing adsorption cycle configuration, inosanganisira kugadzirwa, depressurization, purge, uye pressurization nhanho, inowanzo shandiswa mune inotakurika yekurapa oxygen concentrators.Zvishandiso izvi zvinokwidziridza kukurumidza bhasikoro kwemakoramu adsorption kukwirisa mashandisirwo adsorbent uye kuderedza kushanda kwetsoka.Uyezve, kushandiswa kwediki adsorbent particle saizi kunobatsira kudzikisira misa yekutamisa kuramba uye kuwedzera adsorption kinetics, nekudaro ichivandudza kugona kwese.
Pasinei nekushanda kwechinyakare chinotakurika chekurapaoxygen concentratormagadzirirwo, magadzirirwo azvo echigadzirwa anokonzeresa miganhu, kunyanya mukuzadzisa zvidikanwi zvakasiyana zvinobva mukushanduka kwemamiriro ekurapa kwevarwere kana nhanho dzezviitiko.Kugadzirisa ichi chinomanikidza, pane kuwedzera kutarisa pakugadzira inochinjika-single-mubhedha inotakurika yekurapaokisijeni concentrator masisitimuinokwanisa kuchinjika kune zvakasiyana-siyana zvechigadzirwa.Aya masisitimu anochinjika akagadzirirwa kukwirisa kugadzirwa kweokisijeni kuburikidza nekufananidza-kwakavakirwa optimization masisitimu, kunyanya mumamiriro ekumanikidza swing adsorption- uye pressure vacuum swing adsorption-based technologies.
Mukutsvaga kuchinjika inotakurika yekurapa oxygen concentrator mhinduro, optimization zvidzidzo zvakaitwa kuongorora mashandiro eakasiyana adsorbents, anosanganisira LiX, LiLSX, uye 5A zeolite.Pakati peizvi, LiLSX yakabuda seanotungamira, ichiratidza hunhu hwepamusoro hwekuita.Kunyanya, LiLSX-based flexible pressure vacuum swing adsorption systems yakaratidza kukwanisa kuburitsa okisijeni nemazinga akasiyana ekuchena uye kuyerera, kubva pa93% kusvika 95.7% uye 1 kusvika 15 L/min, zvichiteerana.Izvi zvakawanikwa zvinosimbisa kugona kweinotakurika yekurapa oxygen concentrator tekinoroji kuchinjakumba oksijeni kurapwanekugonesa-chaiyo-nguva kuchinjika kune varwere' vanoshanduka zvinodiwa.
Muchidimbu, kushandiswa kweanotakurika okisijeni concentrators mumusha weokisijeni kurapwa kunomiririra kufambira mberi kwakakosha mukuchengetedza kufema.Nekushandisa misimboti yekumanikidza swing adsorption uye nekumbundikira anochinjika dhizaini marongero, zvishandiso izvi zvinomira zvakagadzirira kusimudzira kugara kwemurwere uye kugadzirisa hutano hwehutano munzvimbo dzepamba.
