保存液是否會(huì)變質(zhì)保存液存放一段時(shí)間后，容易腐爛壞掉。清亮的保存液變渾濁、長(zhǎng)霉菌、長(zhǎng)細(xì)菌、保存液由橙色變成黃色，晚節(jié)不保，令人唏噓。這種肉眼可見的物理性狀的改變，暗示著保存液已經(jīng)變質(zhì)，嚴(yán)重影響企業(yè)形象及產(chǎn)品的品質(zhì)。防止污染，無(wú)疑是研發(fā)、生產(chǎn)、品控過(guò)程的不小挑戰(zhàn)。當(dāng)然，也并不難處理，潔凈車間、添加抗sheng素、穩(wěn)定的緩沖體系等舉措，都能夠從容應(yīng)對(duì)。2、采樣管是否漏液有些保存液，打開箱子或盒子一看，管子漏液了。管壁上“垂涎欲滴”，紙箱上“劣跡斑斑”，沾得手上、實(shí)驗(yàn)臺(tái)上、儀器上等到處都是，有些看的見、有些看不見，實(shí)驗(yàn)環(huán)境很容易受污染。箱子運(yùn)輸過(guò)程，野蠻裝卸或者受航空運(yùn)輸?shù)呢?fù)壓影響，就容易發(fā)生滲漏，整盒整箱都得報(bào)廢。國(guó)內(nèi)還好，到了國(guó)外，退單、退貨、中止合約，非常棘手。故要在采樣管身和管蓋的材質(zhì)遴選、結(jié)構(gòu)設(shè)計(jì)、制造工藝等方面下點(diǎn)功夫，宜使用聚乙烯-丙烯聚合物塑膠及某些特殊處理的聚丙烯(PP)、聚碳酸酯(PC)塑膠等容器，需密閉性好，耐高低溫，可適合多種滅活方式，并做好負(fù)壓測(cè)試。廣州冠狀病毒保存管生產(chǎn)廠家應(yīng)滿足限制或者預(yù)防共生微生物增殖的需要，確保診斷實(shí)驗(yàn)的可靠性。</p><div

style="text-indent:25px">關(guān)于病du采樣管的生產(chǎn)制造：病du采樣管屬于醫(yī)療器械產(chǎn)品，國(guó)內(nèi)生產(chǎn)企業(yè)大多都是按照一類產(chǎn)品備案的，按照二類產(chǎn)品注冊(cè)的企業(yè)很少，近為了滿足武漢等地的緊急需求，有很多企業(yè)都是走“應(yīng)急通道”申請(qǐng)的一類備案許可。病du采樣管由采樣拭子、病du保存液和外包裝等組成。由于沒(méi)有統(tǒng)一的國(guó)家標(biāo)準(zhǔn)或行業(yè)標(biāo)準(zhǔn)，各生產(chǎn)廠家的產(chǎn)品差異很大。采樣拭子：采樣拭子直接接觸采樣部位，其采樣頭的材質(zhì)與后續(xù)的檢測(cè)關(guān)系密切。采樣拭子頭應(yīng)該采用Polyester(PE)合成纖維或Rayon(人造纖維)制成，不能使用海藻酸鈣海綿或木棒拭子(包括竹簽)，拭子頭部的材料也不能為棉花制品，因?yàn)槊藁ǖ睦w維對(duì)蛋白質(zhì)的吸附較強(qiáng)，不易洗脫到后續(xù)的保存液中；而含有海藻酸鈣和木制成分的木棒或竹簽折斷后浸泡在保存液中也會(huì)吸附蛋白，甚至?xí)?duì)后續(xù)的PCR反應(yīng)有克制作用。制造拭子頭的材料推薦使用PE纖維、聚酯纖維、聚丙烯纖維等合成纖維，不推薦棉花等天然纖維，也不推薦尼龍類的纖維，因?yàn)槟猃堫惱w維(類似于牙刷刷頭)吸水性不佳，導(dǎo)致采樣量不足，影響檢出率。采樣拭子材料禁用海藻酸鈣海綿!拭子柄有折斷式、內(nèi)置式兩種。</p><p style="text-indent:25px">病du采樣管的樣本采集流程：1. 鼻拭子：將拭子頭輕輕插入鼻腔內(nèi)，在鼻腔內(nèi)輕刮腔壁。將拭子頭浸入采樣液中，尾部棄去。2. 咽拭子：用拭子擦拭雙側(cè)咽扁桃體及咽后壁，將拭子頭浸入采樣液中，尾部棄去。3、唾液采集器：將唾液吐進(jìn)漏斗，直到液體唾液（非氣泡）量達(dá)到采集管管壁上的要求的唾液線高度。機(jī)體被病du傳播后，病du通過(guò)鼻腔和口腔進(jìn)入到咽喉部，再到氣管和支氣管，進(jìn)而到達(dá)肺泡，肺泡上皮細(xì)胞的病du受體表達(dá)占比高，氣道上皮細(xì)胞、成纖維細(xì)胞、內(nèi)皮細(xì)胞和巨噬細(xì)胞等則占比極低，因此，下呼吸道的病du量明顯高于上呼吸道，呼吸道病du檢出可能性又高于血液。總之，肺泡灌洗液中容易檢出病du核酸，其次是深咳痰，再是鼻咽部，再次是口咽部。因?yàn)椴僮鞯姆奖阈院突颊叩慕邮艹潭龋壳芭R床常用的標(biāo)本是口咽部拭子，其次是鼻咽部拭子，而在某些患者中，口咽部或鼻咽部細(xì)胞中病du量較少或極低，如果只取口咽部或鼻咽部標(biāo)本檢測(cè)，病du核酸就檢測(cè)不到，如能同時(shí)或在疾病過(guò)程中的不同時(shí)間采取多種部位的標(biāo)本進(jìn)行檢測(cè)，會(huì)有助于避免因病du采樣工具的使用不當(dāng)而造成的“假陰性”的出現(xiàn)。如未能72h內(nèi)送至實(shí)驗(yàn)室的，應(yīng)當(dāng)置-70℃或以下保存，標(biāo)本應(yīng)當(dāng)避免反復(fù)凍融。</p><div
