ALZET滲透泵是由這兩部分組成的
發布時間： 2021-04-24 點擊次數： 1039次ALZET滲透泵是體積只有膠囊大小的滲透壓泵，可植入實驗動物皮下或腹腔內，直接或通過導管以 µl/小時的速度持續準確地輸注測試藥劑。這種輸注根據所使用的泵，可以在動物清醒無束縛條件下長持續6個星期。本產品一般由片芯和包衣膜兩部分組成，按照結構特點，可將口服滲透泵制劑分為初級滲透泵和多室滲透泵兩類。初級滲透泵片芯中包含藥物和促滲透劑，包衣膜由高分子材料組成，包裹在片芯的表面。滲透泵片置于含水的環境中時，由于包衣膜內外存在滲透壓差，水分通過包衣膜后形成藥物的溶液或混懸液，在包衣膜內外滲透壓差的作用下，通過膜上的釋藥孔釋放。這種釋藥方式通常適用于在水中有一定溶解度的藥物。多室滲透泵制劑的片芯為雙層片，一層含有藥物及可溶解性輔料，另一層為遇水可膨脹的促滲透聚合物。這類滲透泵多適用于難溶性藥物滲透泵制劑的制備，釋藥過程由聚合物層膨脹產生推動力而將藥物混懸液推出釋藥孔。產品特點：1、確保持續不間斷地均勻給藥；2、膠囊對半衰期短的藥物具有保護作用；3、可以向幾乎任何組織用藥；4、性價比很高的研究工具；5、確保連續不斷得暴露在預定水平的測試藥物下；6、可以執行短效期的蛋白質及縮氨酸給藥；7、提供了動物慢性定量給藥的簡單方法；8、解決了夜間及周末給藥的不便困擾；9、減少了對實驗動物的操作和應激影響；10、足夠小到可以應用到小鼠，及年幼大鼠；11、體積小，可應用于小鼠或幼年大鼠等小動物實驗；12、確保將藥物準確輸送到靶部位，可以向幾乎任何組織用藥；13、使用方便，一次實驗僅需一次給藥，不再需要夜間或周末實驗；14、避免因重復給藥給動物造成的應激，從而減少非實驗因素對實驗結果的影響。
