2、經檢索,專利申(shen)請一種腸器(qi)官仿生芯片(pian)(pian)(pian)(pian)(cn202210104341.8),包(bao)括三層(ceng)(ceng)依次疊(die)放的基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)固定成的整體,其中(zhong)底(di)層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)、中(zhong)層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)和上層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)均為聚二甲基(ji)(ji)(ji)(ji)硅氧烷(wan)材質,上層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)兩側(ce)分別開設(she)有注液孔(kong)和排液孔(kong),注液孔(kong)和排液孔(kong)對應(ying)(ying)中(zhong)層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)與上層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)之間開設(she)有多條微流(liu)通道,中(zhong)層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)對應(ying)(ying)各個微流(liu)通道均開設(she)有用于培(pei)養(yang)腸器(qi)官的培(pei)養(yang)室,底(di)層(ceng)(ceng)基(ji)(ji)(ji)(ji)片(pian)(pian)(pian)(pian)對應(ying)(ying)培(pei)養(yang)室的位置通過刻蝕(shi)作用形成磨(mo)砂。
3、上述腸(chang)(chang)道芯片的(de)設(she)計與制(zhi)備主(zhu)要是(shi)利用多孔膜結構對(dui)(dui)芯片進(jin)行分割(ge),分別接種腸(chang)(chang)細(xi)胞(bao)和血管內皮細(xi)胞(bao)來構建腸(chang)(chang)屏(ping)障(zhang)結構。然后該方法構建的(de)腸(chang)(chang)屏(ping)障(zhang)缺乏相對(dui)(dui)復雜3d結構。
4、有鑒于上述的缺陷,本設計人,積極加(jia)以研究創新,以期創設一種新型結構(gou)的仿生腸器官芯片,使(shi)其(qi)更具有產業上的利用價(jia)值。
