Uvavanyo lweePropati ezixhasayo zeMathiriyeli yeMatrasi

Umbhali: Synwin– Umatrasi wesiko

Imeko yokunxibelelana phakathi kwe-mattress kunye nomzimba womntu iya kuchaphazela intuthuzelo ebonwayo yomzimba womntu kwaye ichaphazele ngakumbi umgangatho wokulala. Kunokwenzeka ukuba ibe ngunobangela othe ngqo wezilonda zoxinzelelo kwizigulane ezihlala ebhedini ixesha elide. Ngo-1998, uPeter no-Avalino [1] bafunda oomatrasi besebenzisa uvavanyo loxinzelelo lomzimba womntu kunye novavanyo oluzimeleyo lokuthuthuzela, kwaye iziphumo zabonisa ukuba oomatrasi abavavanyiweyo babenentuthuzelo engcono kunemiphezulu yeplanga engathintekiyo. Kwi-1988, u-Shelton [2] ucebise isalathisi soxinzelelo (i-Pindex) ngenani elikhulu lohlalutyo lwedatha xa udibanisa umyinge we-avareji yoxinzelelo, i-peak yoxinzelelo, ubukhulu be-pressure peak magnitude kunye nezinye izinto, kwaye zithelekise kunye ne-mattress decompression test effect, ebonisa ukusebenza kakuhle kakhulu. ukuhambelana kakuhle.

Ngo-2000, i-Defloor[3] yenza uphononongo ngempembelelo yeendawo zokulala ezahlukeneyo kuxinzelelo lomandlalo. Uphononongo lubonise ukuba i-30 ° i-semi-sitting position kunye ne-prone position yayinoxinzelelo oluncinci kwi-mattress surface contact, ngelixa i-90 ° indawo eleleyo yayinoxinzelelo oluphantsi kumandlalo. Eyona inkulu, ekwafunyaniswa ukuba isebenzisa umatrasi ogwetyiweyo oqhelekileyo, yanciphisa uxinzelelo lonxibelelwano ngama-20 ukuya kuma-30 ekhulwini. Ngo-2000, u-Bader [4] wenza uphononongo ngobudlelwane phakathi komgangatho wokulala kunye nokuqina komphezulu webhedi, kwaye wafumanisa ukuba abantu abaninzi bayakwazi ukuziqhelanisa nomandlalo othambileyo kunomandlalo oqinileyo. Kwi-2010, uJacobson et al. [5] yenze uphando kwizigulane ezineentlungu ezincinci ezisezantsi okanye ukuqina. Uphononongo lwafumanisa ukuba unxibelelwano lomzimba womntu ngexesha lokulala lunempembelelo kumgangatho wokulala. Ukutshintsha umatrasi oqinileyo kunokuphucula ukungalali kakuhle kwaye kukhulule isinqe sesigulana. Iintlungu zangasemva kunye nokuqina.

Kwiminyaka yakutshanje, abaphengululi baseTshayina baye balwandisa uphando lwabo ngoomatrasi, kwaye umzimba oyintloko usabonakaliswa kubudlelwane phakathi kokunethezeka komatrasi, umgangatho wokulala, ubukhulu bomandlalo, kunye neempawu eziphathekayo. Kwi-2009, uLi Li et al. [6-7] walinganisa isalathisi sokuhanjiswa koxinzelelo lomzimba womzimba womntu ngokutshintsha ubukhulu besiponji kumphezulu womandlalo, kwaye wenza uhlalutyo olubanzi lwe-subjective kunye nenjongo, kwaye wafumanisa ukuba ubukhulu besiponji kunempembelelo ebalulekileyo kwinduduzo yomandlalo. Ngo-2010, iintlobo ezahlukeneyo zoomatrasi zesipontshi zakhethwa, kwaye impembelelo yeentlobo zesipontshi kwinduduzo epheleleyo kunye nendawo yomzimba womntu yahlalutywa kwaye yathelekiswa.

Kwi-2014, xa u-Hou Jianjun [8] efunda impembelelo yezinto ze-mattress kwiimpawu zomzimba womntu kwindawo yokulala, wafumanisa ukuba indawo yoqhagamshelwano phakathi kwe-mattress kunye nomzimba womntu inkulu, kwaye ukudibana kwexesha elide kunokukhokelela ngokulula ekudinweni komntu. Inokubonwa koku ngasentla ukuba uphando kumatrasi ikakhulu lulele kuvavanyo lokusasazwa koxinzelelo, kwaye lukwanqunyelwe kwizinto ezithile. Iindlela zokuvavanya iinjongo zempembelelo yenkxaso yempahla ye-mattress ayinqabile.

Kweli phepha, kukhethwe izixhobo ezi-6 zematrasi eziqhelekileyo, kwaye uvavanyo loxinzelelo kwicala lobunzima kunye novavanyo lokuhambisa uxinzelelo lomzimba womntu lwenziwa kuzo. Impembelelo exhasayo yempahla ye-mattress. 1 Indlela yovavanyo Kwakhethwa umfundi wasekholejini wasekholejini osempilweni. Isifundo sasingenayo imbali yesifo se-musculoskeletal, yayineminyaka eyi-24 ubudala, yayiyi-165 cm ubude, kwaye yayilinganisa i-55 kg. Izinto ezikhethiweyo kolu vavanyo zisisipontshi esiqhelekileyo, i-foam yememori, isiponji esithe nkqo, ukuxinana okubini kwe-foam yokutshiza kunye ne-3D. Ukusebenza koxinzelelo lwezixhobo zoomatrasi kwavavanywa kusetyenziswa umatshini wovavanyo we-American Instron-3365, osetyenziselwa ikakhulu ukuxinana kwezinto. Uvavanyo lokwandisa.

Ukuze kuvavanywe iipropathi zoxinzelelo lwezixhobo zoomatrasi, iperi yeepleyiti zentsimbi ezisikweri ze-10cm×10cm zincanyathiselwe kwiichucks eziphezulu nezisezantsi ngokulandelelanayo ukuze kuqwalaselwe uvavanyo loxinzelelo. Izinto zomandlalo zisikwa zibe yi-cylinder enobubanzi obuyi-6.6mm, ibekwe kwipleyiti yovavanyo esezantsi, ipleyiti yentsimbi ephezulu icinezela kancinane izinto zomandlalo ezantsi, kwaye iyeke ukucinezelwa xa ubukhulu buyi-5mm, kwaye irekhode uxinzelelo ukusuka ekuqaleni koxinzelelo ukuya ekupheleni kovavanyo. . Uvavanyo lokusasazwa koxinzelelo lomzimba lwamkela inkqubo yovavanyo lokunxiba intuthuzelo yeNkampani yaseJapan AMI.

Isixhobo sisebenzisa inzwa yoxinzelelo lwebhaluni, eqokelela idatha rhoqo nge-0.1s ngexesha lovavanyo. Kuvavanyo lokusasazwa koxinzelelo lomzimba, iinxalenye ze-6 ze-vertebra yomlomo wesibeleko, ihlombe, umva, umlenze, ithanga kunye nethole zikhethwe ukuba zivavanywe, kunye neenzwa ze-airbag ezinobubanzi be-20 mm zifakwe kwindawo nganye yokuvavanya. Umhloli ulala phantsi kwi-mattress, kwaye xa idatha yoxinzelelo iya kuzinza, idatha irekhodwa imizuzu emi-2.
