[Gui Cavalcanti] (zita raungaziva kubva kuMegaBots) akataura nenyanzvi yezvokurapa muSan Francisco uye akataura nezvezvinofema. Mubvunzo ndewokuti, tinogona kugadzira uye kutumira yakavhurika sosi vhezheni munguva kubatsira vanhu?
Mishumo inokatyamadza kubva kuItari inoratidza kuti kana hutachiona huchibata vanhu vanotapukirwa, mudziyo wakakosha ndiwo wekufema. Sezvineiwo, vari kushomeka.
Kana zvasvika kune rudzi rwekufemerera runodiwa, dambudziko rinova kunyengera, uye CPAP, BIPAP kana Hi-Flo oxygen NIV zvese zvinobviswa. Aya masisitimu anoita atomize hutachiona uye anovimbisa kuti chero munhu ari pedyo achatapukirwa.
Chatinoda iNIV yakavakirwa pamhino cannula. Iyo sisitimu inonyorovesa mhepo, yoisanganisa neokisijeni, yobva yaramba ichisaidzira mumapapu emunhu. Kana tikakwanisa kugadzira hurongwa huri nyore uye hunoshanda, saka tinokwanisa kuendesa zvirongwa izvi kumafekitari pasi rese tozvipedzisa. Kana fekitari ichitiodza mwoyo, regai vanhu vaite shanduro kumba.
Kana usina chokwadi chekuti unogona kushandisa mhepo inofefetera, unogona kuedza mimwe mibvunzo. Unogona here kugadzira algorithm yekuona kana munhu achida mhepo inofefetera. Tinogona kudzokorodza n95 masks? Tinogona kugadzira n95 masks kumba? Vashandi vanodawo tende rekumanikidza kuti rigare varwere. Izvi zvinonyanya kukosha kana tichida kuvaka nzvimbo dzekurapa mune gymnasium kana hofisi. Chekupedzisira, kana iwe uri nyanzvi yezvekurapa, unogona kudzidzisa vanhu nzira yekubatsira?
Ini ndiri chiremba anesthesiologist/akasimba, saka ndiri ma mechanical ventilation nyanzvi. Chishandiso chinotsanangurwa munyaya ino hachisi mhepo inofefetera, asi yakakwira-inoyerera nasal catheter. Mhepo inopisa uye inonyoroveswa kuitira kuti isaomesa mucous membranes. Inowanzo tengeswa pasi peOptiflow brand uye inofanirwa kuve nyore kugadzira nekupusha gasi kuburikidza ne37-40C mvura.
Kana ndikanzwisisa nemazvo, kuyerera kwepamusoro-kuyerera nasal cannula kuchave kwakakwira zvakanyanya. Pamazinga ekuyerera aya, kunobva mweya wegiredhi rekurapa kana oxygen inogona kunge iri dambudziko guru.
Ndeupi musiyano uripo pakati pewelding oxygen uye oxygen yekurapa? Zvine basa here kana oxygen isina kuchena zvakanyanya?
Kutaura chokwadi, izvi hazvisizvo munjodzi. Vanobva panzira imwe chete. Okisijeni ine ngozi zvekuti inofanira kusefa chero zvinhu zvinogona kuburitsa pfarivari uye kuita.
Ndinotenda kuti zvaaireva ndezvokuti kuchena kwekutsvaira kweokisijeni kunenge kwakangofanana neokisijeni yezvokurapa, nokuti kana zvisina kudaro inokonzera moto (kuputika?) Ngozi nekuda kwezvinosvibisa mumudziyo wekumanikidza.
Storm Raven: Nehunyanzvi kutaura, wakarurama, asi kutaura zvazviri, kuwanda kweokisijeni kunogona kupisa zvinhu izvo zvatove zvisingabatike zvakanyanya uye zvine njodzi. Ichi ndicho chikonzero vane zviratidzo zvekunyevera kwose kwose.
Storm Crow: Pazasi-zvakashata zvachose. Okisijeni inopfuta zvakanyanya uye ibhomba. Friction inogona kukonzera kuputika. Kuda kunzwisisa. Kunyangwe pane dzimwe nzvimbo dzakakwirira mukamuri, inogona kudzima nyore nyore. Welders haafaniri kubata zvishongedzo nemaoko ane tsvina. Iyo isiriyo gasi musanganiswa ine njodzi. Nekuziva kwakanaka, unogona kugadzira yako yekufemerera. Zvakachengeteka kufema oxygen. Mamiriro akakosha anoshanda pakudhivha. Kazhinji inonzi Nitrox. 32% kana pasi ine muchetura zvakanyanya pa 30 tsoka bar. nezvimwe zvakawanda.
MuRaul-Storm Crow ndeyechokwadi. Okisijeni haibatike. Oxygen inongova catalyst, pasina iyo, haungatsva. Uyezve, hazvizoiti kuti zvinhu zviwedzere kuputika. Kuputika kwezvinhu kunoenderana nemakemikari emhando yezvinhu uye makomo aripo. Zvikasadaro, chero mumwe munhu paanobatidza chibatiso chefodya, mhepo yose inobatira moto.
Zee uye Storm Raven. Murazvo wemoto unokonzerwa nekemikari inopisa mukati mehydrocarbon uye oxidant. Muchiitiko ichi, okisijeni ndiyo inonzi oxidant, saka okisijeni ndeimwe yezvinhu zviviri zvinopisa zvinopisa. Zvinoenderana nekufunga kwako, mahydrocarbon haasi nyore kupisa mumhepo isina oxygen. Mukuwedzera, Zee haisi inokonzeresa nekuti inopedzwa zvachose mukuita. Kupisa kunoda mahydrocarbon chete, okisijeni uye sosi yekubatidza. Pamwero wakakodzera, static magetsi anogona kukonzera kuputika.
Ini handikwanise kumiririra chero ani zvake, asi chero bedzi okisijeni ichipfuura neimwe rudzi rwesefa, ini ndichafara kufema O2.
Imwe sarudzo yeokisijeni inogona kunge iri mudziyo unonzi concentrator. Chero bedzi vane magetsi ekushandisa kumusoro (kana kupfuura, ndinofanira kuvimba nemichina yangu), vanogona kupa zvinopfuura 2 L / min 95% O2 kukwanisa munguva chaiyo. Zvishandiso zvakajairika pamusika (kunyangwe ndikafungidzira kuti zvigadziriso zvegiredhi rekurapa, kunyangwe Amazon inozvitengesa).
“Ndinorangarira @PHitjens akange akarara pamubhedha aine bhodhoro reokisijeni nekuti aive negomarara remapapu. Aizoenda kuBrico kunotenga mwenje wewelding nebhodhoro reokisijeni, rinogona kubatsira # oxygen#呼吸#MacGyver https://bricodepot.fr/ catalogue/poste-a-souder-bi-gaz/prod13363/”
Ini ndinoronga kushandisa brazing (acetylene-oxygen) kusonerera furemu yebhasikoro rangu resimbi. Iyo gasi inoputika chivakwa, asi iwe unofanirwa kusungirira bhodhoro. Uye kune mitemo yemunharaunda pamusoro payo.
Mazhinji emazuva ano mains-powered units achasvika 95% pasimba re5lpm. Zvikwata zvekare zviri kunetsekana kudarika 3lpm
Iyo yakanyanya kuyerera okisijeni therapy inenge 30-70lpm, saka zvinosuruvarisa kuti concentrator haina kucheka mustard.
Nzwisiso yangu ndeyekuti hapana mutsauko pakati peokisijeni inoshandiswa pakurapa uye welding pachayo. Mudziyo wakarongedzerwa okisijeni yekurapa ine cheni yakakwana yekuchengetwa uye haina kuputswa. Vanochengeta tangi risina kusvibiswa. Iwe unogona kushandisa tangi nyowani yekuchengetera, wobva wamisa cheni nyowani yekuchengeta uye uichengete. Mubvunzo wangu ndewekuti zvakaoma sei kuzadza tangi remvura. Zvose zvinonakidza. Ko okisijeni concentrator inogona kuwedzerwa kune dhizaini here?
Semunhu ane makore mazhinji ekufema welding ruzivo, iyo oxygen inopa yagara isiri dambudziko. Dhipatimendi redu remoto rakazadzawo muBA yose (midziyo yekufema) kubva kumakambani akadai seAirgas. Hapana sefa inodiwa.
Ini ndiri cryogenic plant opareta kumushandisi weUS. Ini ndinogadzira mvura yeokisijeni kunyanya kumutyairi wekufema oxygen (ABO). Chechipiri, iyo mvura yakafanana inodziya zvakare uye inoshandurwa kuita yakanyanya-kudzvanya gaseous okisijeni yekurapwa kwekurapa nemichina yewelding. Okisijeni ndeyegiredhi rimwe chete. Musiyano chete ndiyo sisitimu iyo yakakwira cylinder yakabatana kune yekupedzisira kushandiswa. Kushandiswa kwekurapa kunoshandiswa kune mapaipi asina oiri uye asina hutachiona, uko mawelder anoshandisa mafuta-anodzivirira (kwete hazvo aripo) uye pamwe midziyo ine tsvina. Kuchena ndiko 94% kana kupfuura. Trace contaminants (senge methane, acetylene, nitrous oxide) inochengetwa pazasi peyero inoshanda kuABO. Kana mwero wetsvina ukapfuura nhanho iyi, irase, chenesa uye uzadzezve tangi kuti uwane saturated sample. Handisati ndambodzorera batch kune imwe nhanho isina kuchengetedzeka mukushanda kwefekitori yangu kwemakore gumi.
Pane jenareta yeokisijeni inotakurika. Sei iwo midziyo imwe chete isingavakwe mumhepo inofefetera kuderedza kudiwa kweokisijeni yepombi uye kuderedza mukana wekuputika? O2 inogadzirwa in situ uye inopedzwa ipapo.
Okisijeni haizoputika. Inotsigira kupisa, asi kushaikwa kwehuni inopfuta kunongoita kuti chitubu chipise zvirinani, ndinofunga zvichange zvichipisa.
Sekuziva kwangu, oxygen inobva kune imwe sosi, uye zvakafanana. Iyo okisijeni inoshandiswa kufema kana kudhivha inoda kucheneswa vacuum isati yazadza zvakare kuti ive nechokwadi chekuchena, nepo masilinda emuindasitiri ari kungodzoka Pakuzadzazve. Ndakashandisa okisijeni yeindasitiri kwemakore mazhinji, uye kana diving respirator yakashandiswa kwemakore mashanu, hapana chakashata. Ndinovimbisa kuishandisa muhupenyu nerufu mamiriro.
Kuti udzivise moto, usashandise waxy chopsticks pamiromo yako. Miromo inooma paunofema. Vanamukoti vepanzvimbo inochengeta vanhu vanorwara vakavaudza kuti vachinje kuKY jelly-kushandiswa kwakasiyana pane zvavainge varonga.
Saizvozvo, okisijeni yakakwana yakakwana inokonzeresa kuti muviri umire kufema. Panofanira kunge paine kashoma kabhoni dhaikisaidhi muropa kuti munhu atange kufema. Handina kuita basa chero ripi zvaro rezvokurapa.
Ndakagadzira gasi welding kubva kuma1960s, uye kufema oxygen kunogona kubvisa kutemwa nemusoro. Isiri-chepfu, haipisi, asi ichapisa zvimwe zvinhu. Dambudziko reCovid 19 nderekuti mapapu akaomarara uye unoda mutsauko wekumanikidza kuti kufema kuitike. Kana ukasashandisa oxygen, mweya woga wakakwana here? Kuda kuziva. Vamwe vedu tiri kutoshanda nesimba
Kune akawanda marudzi emafevetera, kubva kuCPAP kusvika kune akaomarara mafevha ekuchengeta kwakanyanya. CPAP inongopa kudzvanywa kwakanaka kwekubatsira varwere vanofema voga uye kuburitsa nyanzvi dzekufema mumamiriro ezvinhu ekukurumidzira. Izvo zvinhu zvinoshandiswa pakupnea kwehusiku. Ndakagadzira uye ndakagadzira mudziyo wekupedzisira-wakachipa uye uri nyore kugadzira wakagadzirwa nemabhodhoro epurasitiki. Izvo hazvina kuvimbiswa, uye zvinongodiwa kushandisa zvigadzirwa zvemaoko mumatambudziko makuru, kunyanya munyika dzine urombo. Dambudziko nderekuti handizivi kuti ndowaridza sei. unga ndibatsira here?
Wakazadza dambudziko neokisijeni uye wakamisa nhaurirano yese, uchivavarira kubatsira kuponesa vanhu pasi rese. Izvi zvinoshamisa chaizvo. Ndazvikunda ndoenderera mberi ndatenda
MAX, ndiri kuyedza kugadzira musanganiswa weCPAP uye yakazara kumeso snorkel mask. Unogona kundibata nenzira yako here? Ndinoda simba rebhatiri uye rinotakurika. Ndatenda!
Ini ndinotenda kuti iyo Thrompe michina inogona kugadzirisa matambudziko ese. Nekuyerera kwemvura chete, unogona kuwana yemhando yepamusoro yakatsikirirwa mweya isina masara epombi (mafuta).
Ndinogara mutangi rimwe chete kubva kumutengesi wegasi. Musiyano uri mugwaro uye mutengi kuchengetedza nzira. Ndiri kufara kwazvo kukwanisa kuburitsa gasi kubva mutangi rekubatira-ingoita chokwadi kuti haisi acetylene.
Muchokwadi, acetylene ndiyo yaive yekutanga gaseous pain reliever. Chinhu chinonhuwa chichaita kuti musoro wako utenderere zvishoma, izvo zvinogona kukonzera rufu. Saizvozvowo, tambanudza mapepa akanyorova patafura yekamuri yekushanda uye pasi kuti udzore magetsi nemoto
Pamusoro pezvo, vazivi venyeredzi vatatu vakakurumidza kuuraiwa muchadenga chemwedzi vaive ne100% O2 (pasi pe1/3 kumanikidzwa kwemhepo). Mukuwedzera, oksijeni ine chepfu zvikuru.
Musiyano ndewokuvimbisa kuchena. (Ndiri nyanzvi yezvinhu zvipenyu, uye ndakatenga magiredhi akasiyana-siyana eokisijeni.) Asi pakati pewelding nekurapa, pane mamakisi akawanda anogona kugamuchirwa panguva yakaoma.
Pane chimwe chinhu, icho chidiki, asi chinoda kutaurwa. Ko mafuta epombi anoshandiswa kuzora mavharuvhu, nezvimwewo-ndinofunga kuti ikemikari mabayo? Lipid pneumonia? Ndinongoziva nyaya imwe chete, mudhivha aive nemafuta mutangi rake. MD vanofanira kuziva zvakawanda.
Chero zvazvingaitika, isu tinogona kushandisa okisijeni yeindasitiri mune inonzwisisika pedigree-Ini handina kupokana kuti mutengesi achafara kutsausa tangi nekuda kwekukurumidzira-uye kuve nechokwadi chekuti mafuta anounganidzwa mubaffle kana kutora mamwe matanho ekudzivirira.
Ini ndinoshanda muindasitiri gasi indasitiri uye ndinogona kukuudza kuti zvigadzirwa zvakafanana (mvura o2, inenge yese fekitori inosimbiswa nemishonga), asi nzira yavanotakurwa muhumburumbira yakasiyana (yakasiyana skids, kuongororwa kwakawanda kunodiwa)
Kana paine chero mafuta akajairwa mukugadzirwa kweokisijeni, unogona kusakwanisa kutenga oxygen kubva kumutengesi iyeye nekuti inenge iri chimuney. Silicone mafuta, pamwe?
Ziva kuti midziyo inoshandisa okisijeni pasi pekumanikidzwa kwakanyanya uye kuchena kwakanyanya kunofanirwa kunge isina mafuta kana chero zvimwe zvigadzirwa zvinogona kubata moto. Kuwedzera oxygen kumisikidza uye kudzvanywa kunokonzeresa kupisa kune yakaderera tembiricha, kunyangwe pasina mazhenje.
Ndiri nyanzvi yekudhivha uye chiremba wekudhivha. Takagamuchira kudzidziswa kwemurwere kudhivha tsaona kurapwa mumunda wekusanganiswa gasi saturation uye air diving. Hapana mutsauko pakati pekufema oxygen uye welding oxygen, mutsauko chete ibhodhoro raanopinda. Mabhodhoro ekurapa akaputirwa, saka haaite ngura uye anofanirwa kuongororwa nguva dzose, nepo mabhodhoro akasungwa haatariswe neziso rakashama kuti ngura uye kusvika pamwero wakadaro. Kana ari mafuta mutangi, hapana zvachose mafuta muhumburumbira weokisijeni. Iyo diki diki yemafuta pane chero shinda kana vharafu inogona kukonzera kuputika ipapo. Zvese zvishandiso zvinofanirwa kunge zvichisangana ne-high-pressure oxygen inofanira kunge isina mafuta, zvikasadaro ichapisa nekukurumidza. pasina anosiya. Iyi ndiyo chemistry inokosha.
Ndinosimbisa zvakataurwa naNathan. Welding mabhodhoro anogona chete kuongororwa nemaziso; Ndakaonawo mumwe munhu achiti high-purity high-pressure systems inogona kushanda pasina mafuta. Izvi hazvisi nguva dzose. Kune akawanda PTFE base mafuta (Fomblin, Kluberalfa, etc.) akaedzwa uye anogona kushanda pasi pekumanikidzwa kwakanyanya uye kupisa kwakanyanya. Ndinotenda kuti ivo vanogamuchirwawo muhurongwa hwekurapa. Kuongororazve kucharatidza kana hunhu hwavo hwakakwana.
Kushandiswa kwe adsorbent tubular filters kunogona kudzivirira "chemical pneumonia". Ivo vanozotora yakawanda yeVOC kubva kune lubricant uye sparse oxygen kuti iite kuti ipfuure nepakati. Kuwana nhamba huru ye adsorbent tubes kunogona kuva dambudziko. Rimwe dambudziko nderekuona kuzara kweVOC yayo isati yatsiva adsorbent chubhu kana ikashandiswa sefa. Inogona kufungidzirwa zvichienderana neruzivo uye kuyerera kweye adsorbent chubhu inogadzira uye inofungidzirwa kusvibiswa kwemafuta (degassing rate pasi petembiricha uye kumanikidzwa).
Kana iwe ukapfuura kuburikidza nebubbler, mafuta haazopindi mumapapu. Pamwe ndeye 2 redundancy.
Mhoroi, saka izvo zvatinoda chaizvo ndezvekudzvanywa / kudzvanywa mhepo, gadzirisa kune imwe nhanho, wobva wapfuura nepakati pemafuta sefa, uye ipapo kuburikidza nemvura (inochengetwa pane imwe tembiricha) kunyorovesa mhepo. Ndizvo here?
Tine jenareta reokisijeni remwanakomana wangu. Kana magetsi akavhiringwa kana kufambisa kunoda spare oxygen cylinder. Pamberi pemvumo yeinishuwarenzi, shamwari yeEMT yakanyatso kurudzira kuti titenge michina yegiredhi rekurapa, asi inofanirwa kuzadzwa neokisijeni yewelding. Chero bedzi iwe uchisefa panguva yekuzadza kuti ubate chero zvinosvibisa kubva mukati mewelded yekuchengetera mudziyo, unofanirwa kuve wakanaka. Kupfuudza okisijeni kuburikidza nebubbler kunobatsirawo, uye mvura inogona kushandiswa sefirita yekubatsira. Chokwadi chete emergency situations.
Ko okisijeni ichavhuvhuta nemucushion yemhepo kutanga yobva yabvongodzwa mumvura, asi ichitadza kusefa nekunyorovesa mweya unodiwa nemafefetera akadaro?
Ndaimboshanda kuSweden air gas producer AGA (zvino yava chikamu cheGermany Linde Group), uye ndinogona kukuvimbisai kuti hapana musiyano muEurope. Zvinonyanya kudhura kuva nemishonga yakasiyana-siyana uye yehutano gasi nzira dzekurapa. Musiyano chete ndewekuti okisijeni yekurapa inotengeswa inouya nechitupa chinosimbisa kuti igiredhi rekurapa, asi vamwe vasiri. Ingori nzira yekuwedzera mitengo nemari.
Iko hakuna mutsauko zvachose, kungoita mwero wekuchena bvunzo, zvikasadaro iyo okisijeni yemukati mu "welding" okisijeni i99.99%
Musiyano mukuru chete wekufunga nezvemhando. Kuchena kwemasilinda emagetsi emagetsi kwakaderera. Naizvozvo, ivo vanowanzove nemafuta munzvimbo dzeindasitiri. Iyo chaiyo compressor inoshandiswa kuzadza tangi rekuchengetedza inogona kuburitsa iyo yakafanana yeO2.
Musiyano pakati pematanho mana akasiyana eokisijeni (ndege, kurapwa, welding uye tsvakiridzo) hausi iwo mhando yeokisijeni, asi cheni yekuchengeta tangi rekuchengetedza. …Unogona kufunga nezveokisijeni segiredhi rekurapa, nekuti unotanga netangi rakachena risina zvinosvibisa.
Ini handisi chiremba, asi ndiri kutamba paTV - ndinofunga kunyangwe kutorwa kwemhepo kwemuchina kunogona kuita basa rakanaka kana richienzaniswa nekudzora - zvirinani kune zvakanyanya zvakanyanya nyaya dzekufema.

Hi Justin, ndapota tarisa iyi webhusaiti. Vachangowana certification kubva kuSpanish medical institution. Iyo yakavhurika sosi uye ine 2 madhizaini, imwe yevagadziri uye imwe yekugadzira yakawanda.
Kana iwe uine chimwe chinhu chinoratidza kuti mudziyo wakasimbiswa, saka Id inofarira zvikuru kuiona.
Mhoro Gary, ndakakuudza mazuva mashoma apfuura kuti modhi yakabvumidzwa zviri pamutemo neSpanish medical institution. Kuti uwane rumwe ruzivo nezve modhi iyi, ndapota shanya: https://www.oxygen.protofy.xyz/home
Hi, ndinogona kupindura mizhinji yemibvunzo yenyu. Ini ndiri murapi wekufema uye ndiri kugadzira yangu yekufemesa. Nekuda kwemuenzaniso wemazuva ano, mutsara wekutanga wemhepo unoda 50 PSI yemhepo kuti ishande-iyo inotungamirirwa nepneumatically uye kune marudzi maviri, kutenderera kwemhepo kana kutenderera kwevhoriyamu. Mapombi mazhinji anoshandiswa muzvipatara ane volumetric. Yakagadziriswa vhoriyamu uye yakaunzwa kakawanda paminiti. Zvatinofanira kutaura ndezvekuti mazhinji ezviridzwa zviridzwa zvakaomesesa-kwete zvakanyanya kuomarara-Ndakadzidza pamushini iwoyo kuti inonyanya kukosha muchina ndeye MA1, iyo ikozvino yagara ine marongero, saka pamusoro pekufema, ivo Unogona zvakare kufema. , inonzi SIMV. Imwe isingashandiswe zvishoma inonzi auxiliary control. Naizvozvo, chaunoda muchina unogona kupa kudzvanywa kweseti kana vhoriyamu, kubvumira murwere kufema ega, kupa yekutanga kumanikidza (inonzi PEEP), uye kuendesa oksijeni yakasanganiswa.
Mutambo wekare wakanga wakaita sepombi, une pombi nemapombi kwose kwose. Mwana weshiri muenzaniso wakanaka, asi iye zvino chikwata chacho chakanyanya kombiyuta uye chakanatswa. Tarisa iyo $30,000 yemhepo inovhara sezvo iyo sefa zvinhu ichipinda mumavhavha. Vanoda simba 120 uye mweya weokisijeni. Naizvozvo, muchiitiko ichi, usangotarisa muchina, usatarise zviwanikwa zvinodiwa pakushandisa muchina uye manpower anodiwa kushandisa muchina.
Chiri kudiwa nekukasika i "performance specification" iyo Dhipatimendi reDziviriro inogona kupa, iyo inotsanangura izvo midziyo inofanirwa kuita, kwete mashandisirwo emidziyo. Izvi zvinowanzo tsanangura mashandisiro anoita mushandisi mudziyo uye chero kushivirira kubva kune interface maonero. Pane mimwe mibvunzo inoshanda nezvemumwe nemumwe ane chekuita (chiremba, murwere, nyanzvi yezvokurapa) uye nderupi ruzivo rwakananga basa rega rega rine kutyaira zvinodiwa zvemidziyo. Chiremba anopa zviyero zvakajairwa kune vane hunyanzvi hwekurapa matekiniki, vanozogadzira muchina. Iyi tekinoroji yekurapa haina kodzero yekuisa pamberi mabasa eiyo vhezheni. Vanachiremba havazive mashandisirwo emhepo inofefetera, uye havanzwisise kuti HMI yeventilator inowanzorongwa sei. Chekupedzisira, zvipatara zvakawanda zvine hungwaru hazvina simba rakakwana rekubata nezvigadzirwa zvakaderedzwa zvinowanzoitika mumatambudziko akadaro. Pane imwe nguva, iwe hauna hanya nezve chitupa, asi unongoda kuzvichengeta uri mupenyu. Iyo FDA yakataura pachena kuti: "Vasina kubvumidzwa vanodzora vanowanzoipa kupfuura kusave nemhepo." Vanongofunga nezvemhosva.

Maprinta e3D anogona kuita mamwe mabasa nemazvo, sekukopa zvidimbu zvepurasitiki nezvinhu zvakafanana nekuzvibvisa. Asi izvi hazvisi zvese, uye kumhanya kwe3D kudhinda kunononoka. Mamwe maprinta e3D anoshandisa zvinhu zvinoburitsa mhute ine muchetura. Varwere vane pneumonia vanorambidzwa zvachose kushandisa chinhu ichi. Kana ichishandiswa sechikamu chemhepo inofefetera, chikamu hachifanirwe kuburitsa mhute yakadaro.
Mumamiriro ezvinhu aripo, tinoda kushandisa chero chipi zvacho chatinacho, pombi yemhangura, zvichida pvc. Kana pasina chimwe. Zvinonyanya kushanda kuenderana nevhavha iripo pane kugadzira yako modhi uye kutora nguva yakareba ku 3D kudhinda.
Vhiri rakagadzirwa makore anopfuura zana apfuura. Yakaderera tekinoroji zvemukati, zviri nyore kugadzira uye kushanda. Isimbi mapapu.
Nekushandisa webhusaiti yedu uye masevhisi, unobvumirana pachena nekuiswa kwedu kwekuita, kushanda uye kushambadza makuki. Dzidza zvimwe
