本公开的目标是提供一种用于处理塑料零件的改进的或替代的方法。此外还提供一种改进的或替代的药物递送装置。
通过例如独立权利要求的主题可以实现这个目标。其它有利的实施例可以是从属权利要求的主题。
根据一个方面,用于处理包括表面的塑料零件的方法,包括步骤:A)用处理辐射(treatment radiation)照射所述表面的至少一部分以获得改性(modified)的表面区域,所述改性的表面区域相比未改性的表面区域能够更大程度地吸收加热辐射,和B)至少在一个区段中用加热辐射照射所述改性的表面区域使得所述塑料零件在所述改性的表面区域的照射区段所限定的部位(region)中被加热并软化。
通过用处理辐射处理所述表面的至少一部分,该表面可以改变其自身的特性,例如,其光学特性。处理的结果可以是相比未改性的表面区域能够更大程度地吸收加热辐射的改性的表面区域。现在塑料零件的未改性的表面区域相比改性的表面区域对加热辐射可以呈现更强的反射性。对于加热辐射,塑料零件的表面的改性的表面区域相比塑料零件的表面的未改性的表面区域可以具有增大的吸收系数。
通过吸收加热辐射的能量,塑料零件的部位可以软化。在该公开的上下文中的“软化”可以意指塑料零件仅在该部位软化但是不能流动。然而,其还可以意指塑料零件吸收了很多的能量使得塑料零件在该部位中熔化(melt)。塑料零件的熔化部位能够适当地流动。例如,该部位可以被加热到其玻璃过渡温度以上。
该方法的一个方面中,没有用处理辐射照射的塑料零件的表面的至少一部分不能或显著更少地被加热辐射软化,其中该加热辐射在改性的表面区域的照射区段所限定的部位中软化塑料零件。具体地,可以被未改性的表面区域全部或几乎全部地反射的加热辐射被改性的表面区域相当多地吸收。
因而,改性的表面区域可以限定塑料零件被加热辐射软化的部位。因此,通过局部地改性表面区域,可以限定塑料零件的一个或多个局部可软化的部位。
在改性的表面区域所限定的部位中“软化”可以意指改性的表面区域为确定加热辐射供给的能量可以传递至塑料零件内的哪个区段至足以软化该相应的部位的程度的决定性的因素。这使得可以控制通过用处理辐射选择性地照射塑料零件而软化塑料零件的区域。
该方法的一个方面中,塑料零件包括聚对苯二甲酸丁二酯(PBT)。
PBT对以上所描述的方法具有特别好的特性。PBT具有好的熔化点以及合适的吸收和反射性能。
该方法的一个方面中,塑料零件包括聚四氟乙烯(PTFE)。
PTFE可以改善塑料零件的滑动性能。如果塑料零件要在药物递送装置中采用并且塑料零件在药物递送装置的操作过程中移动,那么这特别地有利。
该方法的一个方面中,塑料零件包括在处理辐射的影响下改变颜色以获得改性的表面区域的添加剂。
该添加剂可以例如是染料或颜料。当暴露于某些波长的辐射例如处理辐射时添加剂例如可以变黑。
该方法的一个方面中,塑料零件的改性的表面区域具有与塑料零件的未改性的表面区域不同的颜色。通过用处理辐射照射可以实现颜色的改变。颜色改变可以是改性的表面区域的改变后的吸收性能的一个指示。这意味着通过用处理辐射照射,塑料零件的表面的限定区域可以改变其颜色。
该方法的一个方面中,处理辐射的波长比加热辐射的波长短。因此,高能量的辐射可以用于处理表面。
这里使用的术语“波长”可以指相应的辐射的光谱的主要的波长,如峰值波长或主波长。
该方法的一个方面中,紫外线辐射用于处理辐射。
例如,处理辐射的波长在300nm至400nm的范围内。这个范围的波长特别适于处理反射性的表面以获得改性的表面区域。
该方法的一个方面中,红外线辐射用于加热辐射。
例如,加热辐射的波长在900nm至1000nm的范围内。这个范围的波长特别适于软化改性的表面区域。
该方法的一个方面中,以下辐射中的一个或以下辐射中的两个为相干(coherent)的电磁辐射:处理辐射、加热辐射。
该方法的一个方面中,激光器用于产生处理辐射。
激光器特别适于产生处理辐射,因为其具有可以相对自由地选择的波长,高功率的发射辐射和/或小直径的激光束。因为激光束具有较小的直径,激光器可以在较小的精确限定的区域中击中塑料零件的表面。因此,仅表面的较小且准确限定的部分可以转化成改性的表面区域。通过用激光束扫描,即使用小直径的激光束也可以得到限定图案的改性的表面区域,特别是任意大小的改性的表面区域。
该方法的一个方面中,激光器用于加热辐射。
激光器还特别适于产生加热辐射。加热辐射的功率和波长可以适于要软化的材料,例如适于塑料零件的材料的熔化点、玻璃过渡点或软化点。激光器的使用有助于用加热辐射仅照射改性的表面区域的一个精确限定的区段(子区段)。因此,可以软化改性的表面区域的准确限定的区段(子区段)以及因而塑料零件的准确限定的部位。
该方法的一个方面中,改性的表面区域在塑料零件上形成刻文(inscription)。
因此,可以将包括文字、一个或多个数字、和/或一个或多个符号的刻文添加至塑料零件的表面上。具体地,优选地处理辐射可以用于产生刻文以及限定塑料零件的可软化部位。加热辐射适当地施加至改性的表面区域没有刻文的区段。
该刻文可以指示药物递送装置的类型或药物递送装置容纳和/或递送的药物。刻文可以包括剂量相关的数字,例如指示使用者调出的要通过药物递送装置递送的药物的剂量的大小。
该方法的一个方面中,改性的表面区域在没有用加热辐射照射的区段中在塑料零件上形成有刻文。因此,即使在用加热辐射照射后,该刻文仍然没有改变。
该方法的一个方面中,该方法还包括步骤:步骤B)之前,将塑料零件和另一个零件相对于彼此布置使得形成共同接触区域,在该接触区域中塑料零件机械地接触另一个零件。沿着接触区域在步骤B)中软化的塑料零件的部位的延伸部可以限定出塑料零件和另一个零件应彼此结合的结合区域。步骤B)之后,可以将塑料零件的软化部位冷却,并且塑料零件和另一个零件可以在结合区域中彼此结合。
所述两个零件在接触区域中仅机械接触并且还没有彼此结合。在仅机械接触的方式中,零件可以不永久连接而能够从彼此移除同时没有损伤零件中的一个零件或永久连接。
结合部(joint)可以形成在塑料零件和另一个零件之间。结合部可以包括永久连接,例如,如焊接部的材料连接部。
结合区域中的结合部可以由形成在塑料零件和另一个零件之间的化学联结产生。结合部还可以在不使用化学联结的情况下实现,例如通过用塑料零件的软化材料填充另一个零件的表面中的切口(undercut)。塑料零件和另一个零件可以彼此永久地结合。
该方法的一个方面中,所述另一个零件为另一个塑料零件。
一个方面中,另一个零件能够被加热辐射软化。该另一个零件可以能够在没有通过处理辐射或另一个处理辐射处理的情况下软化。可替代地,该另一个零件的处理可以对于使得另一个零件能够通过加热辐射而被软化而言是必须的。
该方法的一个方面中,所述另一个零件包括PBT,
该方法的一个方面中,所述另一个零件包括PTFE。
可以是,例如塑料零件被加热辐射软化并且两个零件通过冷却而结合。不过还可以是,所述另一个零件也吸收了加热能量。这样的结果是所述另一个零件也被软化。因此,结合部可以是冷却塑料零件和另一个零件的结果。在这个情形中,可以是,第一零件和另一个零件的软化材料彼此混合。这样,结合部具有额外的强度。
该方法的一个方面中,改性的表面区域邻接接触区域。
优选地,在步骤B)中被照射的改性的表面区域的区段邻接接触区域。可以存在这样的实施例,其中改性的表面区域没有延伸在全部结合区域上。
该方法的一个方面中,在步骤B)中,所述另一个零件在邻接接触区域的部位中被加热辐射软化。
该方法的一个方面中,塑料零件的改性的表面区域布置在远离所述另一个零件的塑料零件的侧部上。
例如,可以是这样的情形,塑料零件和另一个零件布置于彼此之上。在这样的情形中,步骤A)中优选地用处理辐射照射远离接触区域的的塑料零件的表面。因此,在背对接触区域的塑料零件的那个侧部上获得了改性的表面区域。因而,在步骤B)中也用加热辐射在远离接触区域的表面上照射塑料零件。结果,在远离改性的表面区域的塑料零件的那个侧部上形成了结合区域。
该方法的一个方面中,塑料零件的改性的表面区域布置在连接面向接触区域的塑料零件的表面和背对接触区域的塑料零件的表面的塑料零件的表面上。
以上描述的方法之一可以用于制造药物递送装置。塑料零件可以被软化以使用在药物递送装置中。
例如可以将用于药物递送装置的另一个零件与用于药物递送装置的已经定位并且优选地固定在药物递送装置的壳体中的塑料零件结合。可替代地,另一个零件可以已经定位在壳体中,并且塑料零件可以随后固定至该另一个零件。塑料零件的表面处理后,可以通过用加热辐射照射改性的表面区域,以软化塑料零件和/或另一个零件以形成结合区域,从而永久地连接塑料零件和另一个零件。因此,通过这个方法,例如即使电磁辐射束不能直接抵达相对于塑料零件布置于其安装位置时的另一个零件,也可以结合该另一个零件和塑料零件。
除制造药物递送装置的方法外,也描述了用于药物递送装置的组件和药物递送装置本身。
药物递送装置具体地用于药品的给送,特别是药物(drug)的给送,特别是病人的自我给送。药物递送装置可以是配送预定剂量的药物的笔式注射器。此外,药物递送装置可以是单次使用或多次使用的注射器。
这里使用的术语“药物”优选地意指包含至少一种药学上的活性化合物的药物制剂。
其中在一个实施方式中,药物活性化合物具有高至1500Da的分子量和/或是肽、蛋白质、多糖、疫苗、DNA、RNA、抗体、酶、抗体、激素或者寡核苷酸、或上述药物活性化合物的混合物。
其中在另一个实施方式中,药物活性化合物用于治疗和/或预防糖尿病或者与糖尿病关联的并发症比如糖尿病视网膜病变、血栓栓塞病症比如深静脉或肺血栓栓塞、急性冠状动脉硬化综合征(ACS)、心绞痛(angina)、心肌梗死、癌症、黄斑变性、炎症、枯草热、动脉粥样硬化症和/或类风湿性关节炎。
其中在另一个实施方式中,药物活性化合物包括至少一种用于糖尿病或与糖尿病关联的并发症比如糖尿病视网膜病变的治疗和/或预防的肽。
其中在另一个实施方式中,药物活性化合物包括至少一种人胰岛素或者人胰岛素类似物或衍生物、高血糖素样肽(GLP-1)或其类似物或衍生物、或exedin-3或exedin-4、或exedin-3或exedin-4的类似物或衍生物。

在一个实施例中,用于药物递送装置的组件或药物递送装置包括塑料零件和在结合区域中牢固地结合至塑料零件的另一个零件。背对结合区域或邻接结合区域的塑料零件的表面可以具有改性的表面区域和优选地未改性的表面区域。具体地,通过用预先给定的电磁辐射照射改性的表面区域,塑料零件能够在改性的表面区域中软化。塑料零件可以在通过用预先给定的电磁辐射照射未改性的表面区域的情况下是不能软化的,特别是在未改性的表面区域中。改性的表面区域可以沿着结合区域延伸。
也就是说,药物递送装置或组件包括塑料零件和另一个零件。塑料零件可以以两个零件彼此机械接触并形成接触区域的方式布置在另一个塑料零件上或旁边。该接触区域可以包括两个零件在其中彼此永久地连接的结合区域。第一塑料零件可以包括具有改性的表面区域和未改性的表面区域的表面,其中,改性的表面区域相比未改性的表面区域有利地能够更大程度地吸收预给定的电磁辐射。预给定的电磁辐射可以适于通过在改性的表面区域中照射塑料零件而软化塑料零件。改性的表面区域可以沿着结合区域延伸。
存在这样的可能的实施例,其中,改型的表面区域覆盖全部结合区域、或仅一部分结合区域。
在一个实施例中,塑料零件布置在另一个零件旁边。改性的表面区域优选地邻接结合区域。
在药物递送装置或组件的另一个实施例中,塑料零件和另一个零件仅在结合区域中彼此结合。
这意味着塑料零件和另一个零件可以不在它们彼此机械接触的全部区域上而仅在结合区域中彼此永久地连接。结合区域例如可以包括焊接部。塑料零件和另一个零件可以在多于一个的结合区域中彼此永久地连接。因此,塑料零件和另一个零件可以不在它们彼此接触的全部区域上彼此连接。而是,例如,它们可以在两个分开的结合区域中连接。在这样的情形中,结合区域中的每个可以在背对结合区域的侧部上被对电磁辐射有较低反射性的表面覆盖。
在药物递送装置或组件的再一个实施例中,药物递送装置为注射笔。
在再一个实施例中,塑料零件为药物递送装置的或用于药物递送装置的剂量调拨(dial)构件。
以上和以下描述的关于该方法的特征还可以应用于药物递送装置或组件,反之亦然。而且,描述的关于不同方面或实施例的特征可以彼此组合。
附图说明
其它的特征、优点及好处在以下的结合附图的示例性实施例的描述中变得显而易见。
图1a、图1b及图1c示出了三个不同的制造步骤中塑料零件的示意性截面视图。
图2a、图2b及图2c示出了三个不同的制造步骤中塑料零件和另一个零件的示意性截面视图。
图3a、图3b及图3c示出了另外三个不同的制造步骤中塑料零件和另一个零件的示意性截面视图。
图4示出了包括塑料零件的药物递送装置的示意性截面视图。
具体实施方式
相同种类的元件和相同作用的元件在图中可以用相同的附图标记标示。
图1a示出了塑料零件1,其中塑料零件1例如可以包括聚对苯二甲酸丁二酯(PBT),并且优选地包括聚四氟乙烯(PTFE),例如Celanex 2404MT。PTFE可以改善塑料零件的滑动性能的。塑料零件1可以附加地包括如“LaserWhite”20/9107的添加剂。塑料零件包括未改性的表面区域5,该表面区域5对于加热辐射例如波长范围在900nm至1000nm之间的激光辐射是反射性的,使得塑料零件1被加热辐射照射时不软化。实际上,在开始处理塑料零件之前,整个表面可以是未改性的。
图1a示出了可以发射处理辐射10的处理辐射源11。处理辐射源11例如可以是发射作为处理辐射10的激光束的激光器,其中激光束可以具有例如300nm至400nm的范围内的、优选355nm的峰值波长。受激准分子激光器(excimer laser)可以适用于处理辐射源。通过用处理辐射10照射未改性的表面区域5,被照射的表面区域变为改性的表面区域4。通过吸收处理辐射10的能量,与没有照射的仍然是未改性的表面5相比,改性的表面区域4可以在其光学特性方面被改性,如改变其颜色,例如从白色变为灰色或黑色。
图1b示出了已经用处理辐射10处理过的塑料零件1的示意性视图。塑料零件1的未改性的表面区域5的准确限定的区域现在已经变化为改性的表面区域4。与未改性的表面区域5相比,改性的表面区域4有利地更好地吸收电磁加热辐射。电磁加热辐射特别适用于软化塑料零件1。
可以存在这样的实施例(未清楚示出),其中改性的表面区域4包括或形成有可以包括例如文字、数字和/或符号的刻文。
图1c示出了在另一个制造步骤中塑料零件1的示意图。现在用加热辐射20照射已经以图1a中的方式预处理过的塑料零件1。图1c示出了发射加热辐射20的加热辐射源21。对于加热辐射源21,例如,可以使用如二极管激光器的激光器。该激光器例如可以发射具有在900nm至1000nm范围内、优选地为940nm的峰值波长的加热辐射20。由于改性的表面区域4已经用处理辐射10进行了预处理,所以相比未处理的未改性的表面区域5,现在它能够更好地吸收加热辐射20。具体地,现在塑料零件1在加热辐射20所照射的改性的表面区域4的一个区段所限定的部位中能够被加热辐射20软化。
图2a示出了用于处理塑料零件1的方法的第一个制造步骤的示意图。图2a示出了塑料零件1和另一个零件2。塑料零件1布置在另一个零件2上。两个零件彼此机械接触并且具有共同接触区域6。塑料零件1和/或另一个零件2可以包括聚对苯二甲酸丁二酯(PBT),并且优选地包括聚四氟乙烯(PTFE),例如Celanex 2404MT。PTFE可以改善塑料零件的滑动性能。塑料零件1和/或另一个零件2可以附加地包括如“LaserWhite”20/9107的添加剂。塑料零件1的未改性的表面区域5背对与另一个零件2接触的塑料零件1的表面,与图1的实施例相似,该未改性的表面区域5用处理辐射10处理。处理辐射10由处理辐射源11发射。处理辐射源11例如可以是激光器。处理辐射源11例如可以具有300nm至400nm范围内、优选地为355nm的峰值波长。通过用处理辐射10处理未改性的表面区域5,该未改性的表面区域5变为改性的表面区域4。
图2b示出了另一个制造步骤的示意图。之前已经如图2a所示以及结合其所描述的用处理辐射10处理过的塑料零件1现在能够吸收加热辐射20的能量至足以软化塑料零件1的程度。加热辐射20由加热辐射源21发射。加热辐射20例如可以具有900nm至1000nm范围内、优选地为940nm的峰值波长。塑料零件1现在能够在改性的表面区域4中吸收加热辐射20的能量,并且将热能量传递至与另一个零件2接触的塑料零件1的相反的表面。因此,另一个零件2也能够吸收加热辐射20的一部分加热能量。吸收的加热能量可以软化塑料零件1和/或另一个零件2。塑料零件1和/或另一个零件2仅在改性的表面区域4所覆盖的区域可以被软化。在之前的制造步骤中没有用处理辐射10处理的未改性的表面区域5对于加热辐射20仍然具有高的反射性。因此,即使加热辐射20击中改性的表面区域4之外的塑料零件1,未改性的表面区域5将全部或几乎全部反射加热辐射20。具体地,未改性的表面区域5将不会软化。
图2c示出了现在在结合区域3中彼此永久地连接的塑料零件1和另一个零件2的示意图。结合区域3被改性的表面区域4覆盖,其中,改性的表面区域4位于背对与另一个零件2接触的塑料零件1表面的塑料零件1的表面上。通过吸收加热辐射20的能量,塑料零件1和/或另一个零件2已经软化。软化的零件可以熔化。熔化的材料可以混合。可附加地或可替代地,软化的塑料零件可以熔化并且填充另一个零件中的切口(未清楚示出)。激光焊接在结合区域中可以形成结合部。例如通过冷却或固化(cure)软化的零件,形成了结合区域3,并且塑料零件1和另一个零件2仅在该结合区域3中结合。在其它区域中,特别是未被改性的表面区域4所覆盖的区域中,不能形成结合区域3,并且塑料零件1和另一个零件2可以在接触区域6中仍然仅彼此接触而没有永久地连接。
图3a示出了制造工艺的另一个变型的第一个制造步骤的示意图。图3a示出了塑料零件1和另一个零件2。塑料零件1布置在另一个零件2的旁边,并且两个零件在一个侧面上彼此接触。接触区域6形成在该侧面上。塑料零件1和/或另一个零件2可以包括聚对苯二甲酸丁二酯(PBT),并且优选地包括聚四氟乙烯(PTFE),例如Celanex 2404MT。PTFE可以改善塑料零件的滑动性能。塑料零件1和/或另一个零件2可以附加地包括如“LaserWhite”20/9107的添加剂。邻接另一个零件2的塑料零件1的未改性的表面区域5的一部分如之前所述地通过处理辐射10处理。处理辐射10由处理辐射源11发射。处理辐射源11例如可以是激光器。处理辐射源11例如可以具有300nm至400nm范围内、优选地为355nm的峰值波长。通过用处理辐射10处理未改性的表面区域5,表面的照射区段变成了改性的表面区域4。改性的表面区域4邻接接触区域6。
图3b示出了随后的制造步骤的示意图。图3a中示出了已经用处理辐射10处理过的塑料零件1。塑料零件1现在能够吸收加热辐射20的能量至足以软化塑料零件1的程度。加热辐射20由加热辐射源21发射。加热辐射源21例如可以是激光器。加热辐射20例如可以具有900nm至1000nm范围内、优选地为940nm的峰值波长。吸收的能量现在可以软化塑料零件1和/或邻接的另一个零件2。塑料零件1和/或另一个零件2可以在改性的表面区域4所覆盖的区域中和/或横向地邻接该区域的区域(未清楚示出)中软化。在之前的制造步骤中没有用处理辐射10处理过的未改性的表面区域5对加热辐射20仍然具有高的反射性。
图3c示出了现在在结合区域3中彼此永久地连接的塑料零件1和另一个零件2的示意图。结合区域3被改性的表面区域4部分地覆盖并且部分地邻接该区域。通过吸收加热辐射20的能量,塑料零件1和/或另一个零件2已经软化。例如通过冷却或固化该软化的零件,形成了结合区域3,并且塑料零件1和另一个零件2仅在该结合区域3中结合。在没有通过吸收能量而软化的其它区域中,这两个零件可以仍然仅彼此机械接触,而没有在接合区域中彼此永久地连接。
图4示出了药物递送装置100的示意图。药物递送装置100包括具有可移动地保持在其中的塞子101的筒102。其它零件可以是用于将剂量调拨套筒安装至驱动单元的安装部。药物递送装置100还包括驱动单元103。驱动单元103可以将远侧方向的力传递至塞子101以向远侧驱动塞子101。驱动单元103可以包括如之前所描述的彼此结合在结合区域3中的塑料零件1和另一个零件2。塑料零件1或另一个零件2可以是剂量调拨套筒。塞子101沿远侧方向(向图4中的左侧)的移动导致可以保持在筒102内的药物从筒102例如通过针105配送。剂量调拨套筒可以包括通过用处理辐射10局部处理剂量调拨套筒的未改性的表面区域5而生成的剂量数字。因而该处理辐射可以用于在剂量调拨套筒上产生刻文以及限定剂量调拨套筒中要被软化的区段。
本发明不限于基于所述示例性实施例的描述中的示例性实施例。确切地说,本发明包括任意新的特征并还包括特征的任意组合,其具体地包括专利权利要求中的特征的任意组合和示例性实施例中的特征的任意组合,即使这些特征或组合本身没有在专利的权利要求或示例性实施例中清楚地说明。
