中文Laryngeal mask airway (LMA) chigadzirwa chinoshanda chakagadzirwa pakati pemakore ekuma1980 uye chinoshandiswa mune general anesthesia kumisikidza nzira yakachengeteka yemhepo. Laryngeal mask airway ine hutano hwakanaka ine zvakawanda zvakanakira, senge nyore kushandisa, yakakwirira budiriro mwero wekuisa, yakavimbika mhepo, kunyandura kudiki, kudzivirira kukuvadzwa pahuro uye tracheal mucosa. Asi sei kusiyanisa kunaka LMA? Nhasi, tora Kangyuan's laryngeal mask airway ine yakakwira musika mugove semuenzaniso kutsanangura maitiro ekutonga kunaka kwelaryngeal mask airway kubva pazasi zvinhu zvitatu.
Chekutanga:Zvinhu zveLaryngeal Mask Airway
Iyo chubhu yakasimudzwa yakachena yakasimba silicone yakasvibiswa neplatinamu, ndeye giredhi rekurapa nekujeka kwepamusoro, yakanakisa biocompatibility uye kugadzikana kwakasimba. Nzvimbo yacho yakatsetseka uye haizotsveri zuva rekupera risati rasvika. Iyo curvature yechubhu inoenderana nechimiro chemuviri wemunhu.
Iyo cuff inogadzirwa nemuchina wekuumba jekiseni uye ine simba yekusanganisa pombi yemvura yakachena silicone zvinhu yakasvibiswa neplatinamu, ine kugadzikana kwakasimba, yakapfava uye yakatsetseka pamusoro, yakanyatso kugadzikana kusangana nevarwere.
Chepiri:Maitiro ekugadzira
Kangyuan laryngeal mask yakagadziridzwa yakazvimiririra neboka reKangyuan muna 2005 uye yakaiswa mukugadzirwa mushure mekuyedzwa kwakasimba. Iyo ine akati wandei patents uye ine mabhenefiti asingaenzaniswi kana ichienzaniswa nemamwe maski elaryngeal. The basic process ndeiyi inotevera:
1) Silicone raw material kusanganisa: ine yakavhurika chaiyo siliconeraw material yekusanganisa muchina kuti ive nechokwadi kunyangwe kusanganisa, uye shandisa frequency kushandura mvura chiller kudzora tembiricha yekutonhora.
2) Extrusion yechubhu: yakazara otomatiki chaiyo extrusion midziyo ine laser dhayamita kuyerwa uye otomatiki yekucheka basa inogamuchirwa kuti ive nechokwadi uye inodzoreka saizi yeKangyuan laryngeal mask airway.
3) Cuff jekiseni kuumba: kushandisa mudzimba yepamberi zvizere otomatiki liquid silicone jekiseni molding muchina, simba kusanganisa zvinhu pombi, microcomputer kudzora midziyo chiito uye parameters.
4) Cuff bonding: yakazara otomatiki yekuparadzira michina inoshandiswa kuve nechokwadi chekuti glue rinoiswa zvakaenzana.
5) Tube kudhinda: Medical drying inki inoshandiswa, kudhinda hakuna chepfu uye hakudonha.
6) Batanidza chubhu uye cuff uye svuura glue: ita kuti kuwirirana pakati pechubhu uye cuff kutsvedze uye zvakanyanya, pasina protrusion.
7) Unganidza cuff inoratidza.
8) Kuongororwa kwekuonekwa: iyo LMA ichaongororwa nemaoko.
9) Kudonha kunoonekwa kwecuff: inflate iyo capsule 1.3 nguva yekuyedza mvura kuti ione kana ichidonha.
10) Yakachena uye yakaoma.
11) Packaging.
12) Ethylene oxide sterilization.
Chetatu:Mhando dzelaryngeal mask airway
Iyo chaiyo maitiro eKangyuan laryngeal mask inosarudza hunyanzvi hwayo. Mushure memakore gumi nemashanu ekubhabhatidzwa pamusika uye kunaya kwemvura, Kangyuan ine mukurumbira wakanaka mumisika yeEurope, America neSoutheast Asia. Uye zvakare, Kangyuan yakagadzira akati wandei e laryngeal mask zvigadzirwa zvine mhedzisiro dzakasiyana kune akasiyana marudzi evarwere, senge imwe nzira yakajairika laryngeal mask airway, imwe nzira yakasimbisa laryngeal mask airway (iyo ventilation chubhu inogona kutenderera pamakona akawanda pasina kupwanya kana kinking) , laryngeal mask airway ine epiglottis bars (kudzivirira chero rudzi rwe reflux), nzira mbiri dzakasimbisa laryngeal mask airway, PVC laryngeal mask airway, nezvimwewo.
