Kuyambira Marichi, kuchuluka kwa matenda atsopano a korona m'dziko langa kwafalikira ku zigawo 28. Omicron imabisidwa kwambiri ndipo imafalikira mwachangu. Kuti tipambane pankhondo yolimbana ndi mliriwu posachedwa, malo ambiri akuthamangitsana ndi kachilomboka ndikuyesa mayeso a nucleic acid.

Pali chiwopsezo cha kufalikira kwa mliri wapano wa Shanghai, ndipo nkhondo yolimbana ndi mliriwu ikuthamangira nthawi. Pofika 24:00 pa 28, anthu opitilira 8.26 miliyoni adawunikiridwa kuti ali ndi nucleic acid ku Pudong, Punan ndi madera oyandikana nawo ku Shanghai.

Pomwe aliyense anali kulimbana ndi mliriwu limodzi ndikuchita mogwirizana ndi kutseka, kuwongolera ndi kuyesa, mphekesera zidafalikira pabwalo kuti "mansalu a thonje omwe amagwiritsidwa ntchito poyesa sampuli ali ndi ma reagents, omwe ndi oopsa", ndipo ena ochezera pa intaneti adanenanso. kuti okalamba kunyumba adawona mphekesera zoyenera Pambuyo pake, sindinkafuna kutenga nawo gawo pakuwunika kwa nucleic acid, komanso ndinapempha achichepere kuti ayesetse kuti asayesedwe ndi nucleic acid. kuyesa kwa antigen.

Kodi nsonga za thonje zomwe zimagwiritsidwa ntchito poyesa ma nucleic acid ndi kuyesa ma antigen ndi chiyani? Kodi pali ma reagents pa izo? Kodi ndi poizoni?

Malinga ndi mphekesera, ma swabs a thonje omwe amagwiritsidwa ntchito pozindikira ma nucleic acid ndikuzindikira ma antigen makamaka amaphatikizira mphuno ndi kukhosi. Ziphuphu zapakhosi nthawi zambiri zimakhala zazitali masentimita 15, ndipo zapamphuno zimakhala 6-8 cm. Opanga zida zodziwira ma antigen, a Mohe Tang Rong, yemwe amayang'anira Medical Technology (Shanghai) Co., Ltd., adalengeza kuti "maphukusi a thonje" omwe amagwiritsidwa ntchito poyesa zitsanzo zomwe mukuwona sizifanana ndi thonje loyamwa lomwe timagwiritsa ntchito nthawi iliyonse. tsiku. Asamatchulidwe kuti "cotton swabs" koma "sampling swabs". Wopangidwa ndi mutu wa nayiloni wamfupi wa fiber fluff ndi ndodo yapulasitiki ya ABS yachipatala.

Sample swabs amakhamukira ndi kupopera ndi electrostatic charger, kulola mamiliyoni a nayiloni microfibers kumamatira vertically ndi mofanana ku mapeto shank.

Kukhamukirako sikutulutsa zinthu zapoizoni. Njira yothamangitsira imalola mitolo ya nayiloni kupanga ma capillaries, omwe amathandizira kuyamwa kwa zitsanzo zamadzimadzi ndi kuthamanga kwamphamvu kwa hydraulic. Poyerekeza ndi miyambo bala CHIKWANGWANI swabs, swabs anakhamukira akhoza kusunga tizilombo chitsanzo pamwamba pa CHIKWANGWANI, mwamsanga elute> 95% ya chitsanzo choyambirira, ndi mosavuta kusintha tilinazo kudziwika.

Tang Rong adanena kuti swab ya sampuli imapangidwira sampuli. Ilibe ma reagents akuwukha, komanso sayenera kukhala ndi ma reagents. Amangogwiritsidwa ntchito kukwapula ma cell ndi zitsanzo zama virus mu virus inactivation preservation yankho la nucleic acid kuzindikira.

Nzika zaku Shanghai zomwe zakumanapo ndi "kuyezetsa ndi kuyezetsa" komanso "kubaya kwa mabanja" zakumananso ndi kuyezetsa kwa ma swabs: oyesawo adatambasula swab pakhosi kapena mphuno ndikusisita kangapo, kenako adatenga chubu m'miyendo yawo. dzanja lamanzere. , ikani chitsanzo cha "cotton swab" mu chubu cha sampuli ndi dzanja lamanja, ndipo ndi mphamvu pang'ono, mutu wa "cotton swab" umathyoledwa mu chubu lachitsanzo ndikusindikizidwa, ndipo ndodo yayitali ya "cotton swab" imatayidwa. mu chidebe cha zinyalala zachipatala chachikasu . Mukamagwiritsa ntchito zida zodziwira antigen, sampuli ikamalizidwa, sampuliyo iyenera kuzunguliridwa ndikusakaniza mu njira yosungira kwa masekondi 30, kenako mutu wa swab umakanizidwa ku khoma lakunja la chubu la sampling ndi dzanja. osachepera masekondi a 5, motero kumaliza sampuli za chitsanzo. elute.

Nanga n’chifukwa chiyani anthu ena amamva zilonda zapakhosi, nseru ndi zizindikiro zina pambuyo poyesedwa? Tang Rong adati izi sizikukhudzana ndi kutolera ma swabs. Zitha kukhala chifukwa cha kusiyana kwa anthu, kukhosi kwa anthu ena kumakhala kovutirapo, kapena chifukwa cha ntchito ya ogwira ntchito yoyesa. Idzatsitsimutsidwa posachedwa kusonkhanitsa kuimitsidwa, ndipo sikudzavulaza thupi.

Kuphatikiza apo, ma sampling swabs ndi zitsanzo zotayidwa ndipo ndi gulu lazida zamankhwala. Malinga ndi malamulo a dziko, osati kupanga kokha kuyenera kuperekedwa, komanso zofunikira zokhwima za chilengedwe komanso miyezo yoyang'anira khalidwe ndiyofunika. Zogulitsa zoyenerera ziyenera kukhala zopanda poizoni komanso zopanda vuto.

The "disposable sampler" ndi mankhwala wamba pazachipatala. Ikhoza kuyesa magawo osiyanasiyana ndipo imagwiritsidwanso ntchito m'machitidwe osiyanasiyana ozindikira. Simapangidwa mwapadera kuti azindikire ma nucleic acid kapena kuzindikira ma antigen.

Choncho, ponena za zipangizo, kupanga, kukonza, ndi kuyendera, ma swabs a sampuli ali ndi miyezo yolimba kuti atsimikizire kuti alibe poizoni komanso alibe vuto, ndipo angagwiritsidwe ntchito molimba mtima.

Kuyesa kwa nucleic acid ndi njira yofunikira yoletsa kufalikira kwa mliri. Pakakhala zochitika zaposachedwa komanso zingapo m'magulu angapo, ndikofunikira kuyang'anira kuchuluka kwa nucleic acid kwa ogwira ntchito kangapo.

Pakadali pano, Shanghai ili pagawo lovuta kwambiri popewa komanso kuwongolera mliri. Osafalitsa mphekesera, musakhulupirire mphekesera, tiyeni tisunge "Shanghai" ndi mtima umodzi, kupirira kudzapambana!
