Description

一次性经鼻脑靶向给药装置 技术领域
本实用新型涉及一种一次性经鼻脑靶向给药装置。
背景技术
在治疗脑部疾病如多发性硬化症、帕金森病、癫痫症、阿滋海默病、脑部肿瘤、艾滋病及其它传染性疾病和急性中毒时，医学上一直存在着一个难题，即：如何克服血脑屏障，使药物能够迅速进入中枢神经系统（central nervous system, CNS）内以发挥药效作用。目前临床上应用较多的方法是通过可逆性开启血脑屏障，鞘内注射以及颈动脉注射给药，使药物透过并进入中枢神经系统。但是，这些方法在操作技术上要求高、安全风险大，在应用上受到一定制约。基于鼻腔的特殊结构，通过鼻腔给药治疗脑部疾病具有非侵入性、脑生物利用度高、可以绕过首次通过代谢和体循环和血脑屏障等优点，且方便操作。
在最近几年，许多研究都证明了只要通过恰当的手段，药物直接通过鼻腔进入脑是完全可行的。鼻腔嗅区是人体中唯一一处神经细胞与周围环境直接接触的位置，通过神经细胞（嗅神经、三叉神经）通路、细胞间隙通路或与脑部静脉窦直接相连的微血管通路均能实现药物经鼻脑靶向的传递。但如何将药物有效地通过鼻腔-脑的途径递送如中枢神经系统，而避免过多的通过鼻腔粘膜直接吸收进入外周循环是一个有待解决的难题。
已有大量的研究聚焦于通过制剂的改变来提高药物经鼻-脑途径的吸收效率，包括增加药物在鼻腔的滞留时间、提高鼻腔粘膜的通透性、药物分子修饰、改变药物的粒径、用脂质体增加药物的渗透性等方法，也形成了不少专利。专利CN101600417A公开了一种经鼻施用的多巴胺盖伦凝胶制剂，通过亲脂性系统提高药物的经鼻脑靶向吸收的生物利用度。专利CN102370623A公开了一种液态脂质微粒的制备方法用于经鼻脑靶向给药。专利CN102174080A公开了通过噬菌体展示技术获得的一个多肽，用于修饰药物载体以实现经鼻脑靶向给药效果。专利CN1839799A公开了一种通过凝集素修饰药物载体，以增加药物在鼻腔中滞留时间，从而实现经鼻脑靶向给药效果的方法。也有专利着眼于通过给药装置来实现经鼻脑靶向递送药物的目的，专利CN201280021497公开了一种鼻药递送装置，该装置通过氢氟烷烃推进剂是鼻内剂型气雾化，并通过喷嘴将药物羽流递送至鼻腔嗅区，从而吸收入脑，其药物进入嗅区的比例为64.2%以上。
但现有技术中的鼻腔嗅区给药装置还存在有以下缺点：1）给药装置的喷嘴虽然能将药物送至鼻腔嗅区，但喷嘴不能伸入到鼻腔嗅区，所以不能将药物全部送至鼻腔嗅区，如现有技术中，只能将64%左右的药物送至鼻腔嗅区，造成药物的浪费，也会给病患造成不必要的经济损失。2）给药装置不是预封装设计，每次给药都需重新装药、配药，操作比较繁琐，也浪费时间，特别是对于医院急救、战场神经性毒气解毒等需要快速给药的场合，很有可能会因为装药、配药时间的浪费而不能对病患进行及时处理。3）因每次给药都需重新配药、给药使得储存药物的容器需要经常打开，容易使药物发生变质而不能使用，特别是对于一些存储稳定性低的药物容易造成浪费。4）每次给药都要进行清洗、消毒的繁琐步骤，若清洗、消毒不彻底容易造成交叉污染。

具体实施方式
下面结合说明书附图对本实用新型作进一步描述。
如图1所示，一次性经鼻脑靶向给药装置，包括给药器，所述给药器包括具有内腔的且用于存放制剂的容器，该容器为可挤压容器1，该给药器还包括与可挤压容器1连通用于将容器中的制剂导入鼻腔的导管2及设置在导管2的一端的喷雾头4，导管2的另一端连接在可挤压容器1上以使导管2的管腔与可挤压容器1的内腔连通，导管2的设有喷雾头4的一端可经人体的总鼻道伸入到中鼻甲对应的水平位置以上的鼻腔嗅区，该给药器还包括用于将可挤压容器1的内腔和导管2的管腔隔离且在压力作用下发生破裂的压力敏感膜3。
本例中，压力敏感膜3设置在可挤压容器1和导管2的连接处。
本实用新型的给药器还包括设置在导管2的设有喷雾头4的一端上的鼻腔适配器6，鼻腔适配器6用于缓冲导管2对于鼻腔粘膜的直接刺激。具体地，鼻腔适配器6成锥形包裹于导管2的外周，鼻腔适配器6的材料选自医用硅胶、氯丁橡胶、顺丁橡胶、天然橡胶、丁晴橡胶、三元乙丙橡胶中的一种。
本实用新型的导管2为软管，其外径为0.1~50毫米，其材料选自医用硅胶、乳胶、塑料、热塑性弹性体（TPE）中的一种。
本实用新型的喷雾头4具有1个或1个以上的直径为0.1~1000微米的孔5。优选为1~100微米。
本实用新型的可挤压容器1为在外力作用下能够发生变形使容器内压力发生改变从而使压力敏感膜3破裂的容器，其材料具有医用材料的生物相容性，一定的弹性和韧性，稳定性好，优选自聚酯类、聚氨酯类、有机硅类、聚烯烃类、聚丙烯酸酯类、氟塑料中的一种或一种以上。
本实用新型的给药装置还包括预封装在可挤压容器1内的制剂。该制剂为可直接给药的制剂。该可直接给药的制剂可以为可直接给药的粉末状制剂或者也可以为已配置完成的可直接给药的液体类制剂。
上述中，制剂可以为生物活性物质，生物活性物质选自小分子非肽非蛋白质药物、肽类/蛋白质药物、天然动植物及其提取物、诊断剂中的一种或一种以上。
本实用新型的给药装置的工作原理：
制剂存放于可挤压容器1内，当需给药时，将导管2的带有喷雾头4的一端经人体的总鼻道伸入到中鼻甲对应的水平位置以上的鼻腔嗅区，然后用手挤压可挤压容器1，压力敏感膜3在可挤压容器1受到一定程度挤压后，发生破裂，可挤压容器1的内腔与导管2的管腔连通，进一步通过挤压可挤压容器1使制剂进入导管2内然后通过导管2上的喷雾头4雾化后喷至鼻腔嗅区，进而直接吸入脑，在中枢神经系统发挥治疗作用。
本实用新型的给药装置具有如下优点：
1）一次性给药装置：给药装置采用简洁的设计，并用相对廉价易得又安全的材料制备，免除了给药装置的重复清洗、消毒的繁琐步骤，更降低了交叉污染的潜在隐患。
2）预封装设计：在使用前，通过挤压使得压力敏感膜破裂从而将存放在可挤压容器内的制剂直接用于给药，避免传统给药器吸药配药的过程，尤其适用于医院急救、战场神经性毒气解毒等需要快速给药的场合。
3）导管用于鼻腔给药：由于人体鼻道狭窄，一般给药装置无法探入鼻道深部进行给药。绝大部分药物都无法进入鼻腔嗅区，更无法实现鼻腔脑靶向的给药目的。本实用新型给药装置通过导管配上生物相容性好、质地柔软的鼻腔适配器，使得给药位置能够深入到总鼻道接近鼻腔嗅区的水平位置，大大提高了药物进入局部嗅区的靶向剂量，避免了药物经鼻粘膜吸收入外周循环的浪费，同时也最大程度降低了药物的外周副作用。
4）喷雾头的多孔设计：在导管顶端接上一个含有大量微孔的喷雾头，在一定推注压力之下，能够将药物尽可能的气雾化，使之充分与鼻腔嗅区神经接触，提高脑靶向给药的生物利用度。
以上对本实用新型做了详尽的描述，其目的在于让熟悉此领域技术的人士能够了解本实用新型的内容并加以实施，并不能以此限制本实用新型的保护范围，凡根据本实用新型的精神实质所作的等效变化或修饰，都应涵盖在本实用新型的保护范围内。
