A Heat Moisture Exchanger (HME)ndiyo imwe nzira yekupa humidification kune vakuru tracheostomy varwere. Kuchengeta nzira yemhepo yakanyorova kwakakosha nekuti inobatsira mavhinga matete kuitira kuti akosore. Dzimwe nzira dzekupa hunyoro kunzira yemhepo dzinofanira kushandiswa kana HME isipo.
Zvikamu zveHEM Mafirita
Izvo zvikamu zveHME mafirita zvakanyatsogadzirwa kuti ive nechokwadi chekushanda kwakakwana. Kazhinji, mafirita aya ane imba, hygroscopic media, uye bhakitiriya / hutachiona hwesefa. Imba yacho yakagadzirirwa kuchengetedza zvakachengeteka sefa mukati memurwerekufema dunhu. Hygroscopic media inowanzo gadzirwa kubva kune hydrophobic zvinhu zvinonyatso kubata uye kuchengetedza hunyoro hwakafemerwa. Panguva imwecheteyo, bhakitiriya / hutachiona hwesefa hunoita sechivharo, kudzivirira kudarika kwehutachiona hunokanganisa uye zvidimbu.
Unyanzvi Zvimiro zveHME Mafirita:
HME sefa inoshandiswa pakufema kwemurwere kudzivirira chero kusvibiswa kwemuchinjiko.
Yakakodzera kune vanongoerekana vafema varwere vane tracheostomy chubhu.
Inoshanda sefita nzvimbo: 27.3cm3
Luer Port yemasampuri egasi ari nyore ane kavha yakasungwa kubvisa njodzi yekurasika.
Round ergonomic chimiro chisina mipendero yakapinza inoderedza kudzvanywa kwekumaka.
Compact design inoderedza uremu hwedunhu.
Kudzikira kuderera kuyerera kunoderedza basa rekufema
Kazhinji ine furo kana bepa rakaiswa munyu wehydroscopic senge calcium chloride
Bhakitiriya nehutachiona mafirita zvine hunyanzvi hwekusefa kwe> 99.9%
HME ine humidification kunyatsoshanda >30mg.H2O/L
Inobatanidza kune yakajairwa 15mm yekubatanidza pane endotracheal chubhu
Mechanism yekudziya uye humidification
Iine furo kana bepa rakaiswa munyu wehygroscopic senge calcium chloride.
Gasi rakapera nguva rinotonhora sezvarinoyambuka membrane, zvichikonzera kudzika uye kusunungurwa kwehuwandu enthalpy ye vaporisation kune HME layer.
pakufemerwa kupisa kunonyunguduka kunoburitsa iyo condensate uye kunodziya gasi, munyu wehygroscopic unoburitsa mamorekuru emvura kana mhute yadzikira.
Kudziya uye humidification saka kunodzorwa nehunyoro hwegasi rapera uye kupisa kwepakati kwemurwere.
Sefa layer iripo zvakare, ingave electrostatically chaji kana pleated hydrophobic layer, iyo yekupedzisira inobatsira kudzosera mwando kugasi sezvo condensation uye evaporation kunoitika pakati pemapleat.
Mechanism yekusefa
Kusefa kunowanikwa kune zvimedu zvakakura (> 0.3 µm) neinertial kupindirana uye kubata.
Zvidiki zvidiki(<0.3 µm) zvinotorwa neBrownian diffusion
Kushandiswa kweHME Filters
Iwo anoshandiswa zvakanyanya muzvipatara, makiriniki, uye zvirongwa zvekuchengeta kumba. Aya mafirita anowanzo kubatanidzwa mumaseketi ekufambisa, anesthesia kufema masisitimu, uye tracheostomy tubes. Kuita kwavo kwakasiyana-siyana uye kuenderana nemhando dzakasiyana dzemidziyo yekufema inovaita chikamu chakakosha chekuchengetedza kufema.
Semutengesi anotungamira uye mugadziri wemishonga inodyiwa, Shanghai Teamstand Corporation yakazvipira kupa mafirita emhando yepamusoro eHME anosangana nezvinodiwa nenyanzvi dzehutano. Zvigadzirwa zvavo zvakagadzirirwa nekutarisa kunyaradzwa kwevarwere, kushanda kwekiriniki uye kutonga kwehutachiona, zvichiita kuti vave sarudzo yakavimbika yezvivakwa zvehutano pasi rese.
Isu tinopa yakafara uye yakazara sarudzo yeHMEFs ine akasiyana ekuita, saizi uye maumbirwo kuti tive nechokwadi chepamusoro chevatengi kusarudzwa uku uchizadzisa zvese zvinodiwa zvekiriniki.
