Izihlunu "sokukhanya" Ngenxa "indawo yediskhi" ukuze Imitativi Heart?

Ukuba ezi zixhobo ukusombulula ingxaki amandla sasingakwazi khangela aphesheya kolwandle, kwaye zilinywe kubantu abanesifo sentliziyo, intliziyo mechanical, kuzo indlela womelele kwaye zomelele ngaphezu langoku kakhulu [1]. Nangona uphando lwakutsha nje lubonisa - intliziyo uvelisa peptide atrial natriuretic [5]. Ngoko ke, ukuba ukuthetha malunga ophambili isipho intliziyo ngumntu ixesha elide ziya kuba kusasa, kwaye ulawulo entsonkothileyo kwentliziyo ikwafumaneka nayo kwi-mbutho akunakwenzeka kwixa elizayo xa zithelekiswa sokwenziwa. Kodwa ke kwizigulane abagulela ukufa, nto leyo kakhulu eninzi (malunga 17 ezigidi ehlabathini lonke [2] kunye nesifo sentliziyo phantse kwindawo yokuqala!) Ndicinga intliziyo ngumntu xa lingekho donor - ndlela kuphela ngaphandle. Kule meko ke, umbuzo yayo indalo intliziyo ngumntu, ukutya akunyanzelekanga ukuba kugesi rhoqo, nto leyo eyimfuneko ukuze ubomi tsala ngokwakhe ngaphandle, lubalulekile kakhulu. Ngamanye amaxesha ezi iibhetri nobunzima malunga-10 kg [4]. Nangona akukho eyenye ibhetri compact ngakumbi, ngaphandle kokuba ukusetyenziswa elincinane reactor yenyukliya. Development malunga nokudala reactor onjalo lwaqhutywa kwi-USSR, (ngelishwa andithanga ndikukhumbule umthombo) kodwa wayeka bobabini ukusuka ingozi kule fowuni, kwakunye ngenxa yeengxaki yobugcisa indalo yayo. Ukuba ingxaki kwentliziyo ngumntu liyimfuneko kuphela ukuba abantu abagulayo, umba izinto amandla eyiyo esincinane musa ukuba ezibiza kakhulu kubo bonke abantu abasebenzisa Kwiiselula kunye nezinye izixhobo. Ke ukuba nangoku loo meko, ngoko ithemba ukuvela kwi mithombo ngamandla elizayo kufuphi ukuba musa kufuna ixesha elide akuba, andingi. Ngoko ke, ndagqiba kwelokuba abuyele emoyeni kunye zomzimba. Ukuba uyakwazi ukusebenzisa pump umoya intliziyo ngumntu ngaphakathi emzimbeni, ngoko kutheni ukusebenzisa umoya emiphungeni. Njengoko kwakusazeka kwikhondo kwi nokwakheka amalungu emiphungeni ngokwabo akukho izihlunu kwezihlunu, kunye nokwandiswa kunye spadenie olunikiweyo izihlunu uvalo kwaye intercostal al. Musculature. Ngaloo ndlela umoya zingasetyenziswa njenge impompo leyo nokusukelana umoya yaye bephefumla entliziyweni ukungavani efanayo nezibe "inyama negazi" iya kubonelela umsebenzi wakhe ngaphandle neebhetri. Ekuqaleni, ngokuqinisekileyo licebo crazy kakhulu, yaye njengoko kudla ngokwenzeka kwinzululwazi, wonke umntu uya kundihleka kuyo. Ingakumbi ukususela andikho unjingalwazi ayikho ingaba umfundi yonke intliziyo ubomi bakhe (ngokukhuhla iblukhwe zakhe kwi-ofisi), okanye umqeshwa zeziko kwentliziyo. Ke kula mava abuhlungu, yaye kudala ukufunda imbali inzululwazi, ndingatsho ukuba uninzi inzululwazi kunye ne umsebenzi-nkqubo omkhulu ngokuqhelekileyo emdaka ezinezothe, ngoko kakuhle, le mbono yokuba umntu, ngoko undixelele "ukuboleka" yaye akukho okubi ukuhlawula ingqalelo kuyo. Kukho nezinye iindlela - kungaba othile ukuba sele kutshata, kodwa akanakukwazisa. Ndiyakholwa ukuba iingcinga ayide ikwazi ukuzimela, nkqu ekukhanyeni imeko ngasentla opisnoy kum nezesayensi. Kodwa ke andiyi kuba apha ukupeyinta zonke iinkcukacha, ndiya ukuchaza imibuzo kakhulu leyo kufuneka ayeke kwi yokucombulula lo mbono. Ndiyathemba abantu azi uya kuyixabisa zonke ngeliso nangengqwalasela kugxininisa iingxaki amathemba isisombululo kule magazini. Umzekelo:

1 Indlela ukuphumeza nokulinganisa indlela kwemithambo kunye nemibhobho ukuba baninyanzela izithuthi ayahamba na iindlela umoya sokuphefumla lona igazi, ngenxa basafunda zobukhulu bentliziyo sokwenziwa womatshini, okanye ezifana?

2 Ingaba kwanele na uxinzelelo lomoya ukuba kwakuza unciphiso iyathelekiswa umsebenzi zentliziyo? It ngokwezibalo kufuneka kubalwe. Kusenokufuneka xi umoya akwenzeki ukuba ondle ukuqeqesha izihlunu, ngoko umbuzo lo mbuzo: ingaba ukuqeqesha izihlunu uvalo kunokwenzeka kangangoko ukuba umoya isekelwe phezu uxhathiso kwaye ukuqinisekisa ukusebenza okuqhelekileyo intliziyo iisoyi kunye ukutshintshiselana igesi emiphungeni. Kakade ke, umntu onjalo akayi kuba nako ukubaleka, kodwa ukuba uyakwazi ukusebenzisa i eqhelekileyo, ngoko umntu ngentliziyo ngumntu ukuze akwazi ukuhamba. Kakade ke, umntu uthi kutheni usebenzise izihlunu enamandla ngakumbi ngenxa yale njongo - ezifana imilenze okanye iingalo (wakhuph 'intliziyo ngumntu) kodwa ke izihlunu uvalo kunye umoya le physiologically kangcono. Tk imiphunga njengoko intliziyo ukuphendula ekwandeni CO2 igazi, yaye ngoko ke akunyanzelekanga ukuba umlawuli olongezelelweyo. ie kunye nokwanda CO2 emzimbeni nokwanda kwaye ngokunjalo nemfuneko yokuba obadlisa ubomi nokunyusa nobunzulu nokuphefumla nokomeleza intliziyo. Ngoko xa uphelelwa ngumphefumlo kuya kwenzeka kwaye bandile yentliziyo. Kodwa kuqala kuyimfuneko ukuba ukubala uze baqhube imifuniselo kwizilwanyana.

3 Ukuba aba izihlunu akwanelanga, ungasebenzisa ezinye izihlunu nokuba skeletal kodwa senziwe ngendlela nzima ngakumbi (Andiyi kungena iinkcukacha.)

Nangona Andikwazi ukuthatha ingqalelo izinto ezininzi, kwaye le projekthi okwangoku xiya. Uxolo Akukho ixesha ukuyenza loo nto, ngokuba ngoxa ezindlebeni zibandakanyeke disorganization kunye tape elibomvu inkqubo yemfundo mihla, nakubeni oko unako ukuyenza le mba, ukuba bekukho ixesha kunye nemali ... xa kunokwenzeka, eli nqaku liza kuba luncedo kumntu ke. Mhlawumbi ukuba andizange ndikucinge ukuphatha ukuqonda ingcamango yam, ubuncinane ingqalelo iisampulu anikwe oko inegalelo isisombululo sayo.
