用于料带的卷绕装置及药剂分配器
相关申请的交叉引用
本申请基于2022年10月27日提交的中国专利申请202211339731.X主张其优先权,此处通过参照引入其全部的记载内容。
技术领域
本公开内容涉及一种卷绕装置,具体地涉及一种用于料带的卷绕装置和包括该用于料带的卷绕装置的药剂分配器。
背景技术
在现有的药剂分配器中,料带、如药带的卷绕是一个十分重要的工序。参考图1,现有的料带卷绕装置通常包括卷绕轴10和安装于卷绕轴10的收料轮20,其中卷绕轴10能够通过传动机构与动力源相连,从而在动力源(例如手动动力源或者电机)的驱动下转动,同时卷绕轴10会带动收料轮20转动,从而将料带30卷绕在收料轮20上。
收料轮通常以与给料机构(未示出)相同或者呈特定传动比的固定转速沿转动方向R转动,来对应卷绕给料机构提供的料带30。但是,随着收料轮20所卷绕的料带30的层数增加,收料轮20最外圈的卷绕直径,即有效卷绕直径也会随之增大,从而导致收料轮20的卷绕线速度大于给料机构的给料速度,使得收料轮20与给料机构间的料带所承受的张力F增大。当张力F大于预定的值时,料带30会由于张力过大而被拉细,造成厚薄不均、甚至被拉断。
对于药剂分配器来说,收料轮每转动一次所卷绕料带长度的增大,还会导致药剂分配器中的其他部件的相对位置发生变化。例如对于使用泡囊药带的药剂分配器,正常工作时,通过给药机构的药剂分配作用经剥离后的泡囊药带上的泡囊开口能够正对进气歧管的气道结构,从而便于用户吸入药剂。同时,收料轮对应卷绕被剥离的例如药带盖片的料带,以避免对用户获取药剂的过程造成干扰。
但是,当收料轮的有效卷绕直径增大时,收料轮每转动一次所卷绕的料带的长度增大。这时,泡囊开口受到的被卷绕的料带的作用力也相应增大,使得泡囊开口在被卷绕的料带的作用下运动,从而与气道结构的相对位置将发生大的变化甚至是完全错位,由此造成用户无法获得药剂或者充足的药剂,使得药剂分配器无法正常使用

在本公开内容的描述中,需要说明的是,除非另有明确的规定和限定,术语“设置”、“设置有”、“设有”、“安装”应做广义理解,例如,“安装”可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本公开内容中的具体含义。
本公开内容的卷绕装置可用于药剂分配器,药剂分配器是一种分配药剂以用于向患者给药的仪器,当药剂容置在药剂分配器中并经由药剂分配器分配后,能够便于患者将药剂吸入肺中或者施加在鼻腔中。
药剂分配器通常包括外壳、用于承载粉末状药剂的带状药剂载体、用于分配药剂的给药装置、用于将带状药剂载体中的料带、泡罩带分离的剥片装置以及与给药装置、剥片装置配合卷绕料带的卷绕装置。常见的带状药剂载体是包含多个离散剂量的粉末药物的泡罩条带,其布置于壳体内。给药装置能够在壳体内引起泡罩条带的运动来分配药物,剥片装置能够剥离料带和泡罩带,从而获取并分配一定剂量的粉末状药剂于进气歧管的气道处,便于患者通过药粉吸入装置的吸嘴和进气歧管的气道吸入粉末状药剂以进行治疗。同时,卷绕装置能够卷绕剥离后的料带,以避免料带卷入运动机构或者动力源而影响药粉吸入装置的正常工作,甚至造成药粉吸入装置的损坏。
卷绕装置随着给药装置同步运动,与给药装置一样通过转动规定的角度来相配合地卷绕料带。但是,在卷绕装置不断卷绕料带的过程中,收料轮的有效卷绕直径将逐步增大,由此造成收料轮的线速度大于给药装置的给药速度,从而使得卷绕装置与给药装置间料带的张力增大。在被卷绕的料带的拉力作用下,泡囊带上的药剂的位置将发生改变,由此造成药剂与气道的错位。当前述张力过大,还可能造成料带断裂。
因此,为了避免卷绕装置在卷绕料带的过程中,由于有效卷绕直径的增大引起卷绕装置转动一次所卷绕料带的长度增大,造成剥离后的泡囊开口与进气歧管的气道的错位即药剂与气道的错位以及料带所承受的张力太大而造成料带的断裂,有必要设计一种改进的卷绕装置。该卷绕装置能够补偿因收料轮的有效卷绕直径增加而每次转动所增加卷绕料带的长度,由此保证收料装置每次转动所卷绕料带的长度的一致性,从而避免药囊与气道的相对位置发生变化以及料带由于张力过大而断裂,进而避免药剂分配器无法正常运转。下文将结合附图详细描述根据本公开内容第一方面的卷绕装置。
图2示例性地示出了根据本公开内容的用于料带的卷绕装置100。参考图2,该卷绕装置100包括驱动部件1、导向件2、弹性体3和收料轮4。图3示例性地示出了驱动部件1的结构。图4示例性地示出了导向件2的结构。图5和图6示例性地示出了收料轮4的结构。参考图2至图6,驱动部件1包括驱动轴11,并绕该驱动轴11的外周设置有带有第一倾斜表面13的第一台肩部12,该第一倾斜表面13例如可以构造成围绕驱动轴11的螺旋形。驱动部件1还包括位于其底部的驱动底盘110,被配置为能够通过驱动底盘110与外部动力源配合,从而在外部动力源的驱动下转动。
导向件2安装于驱动轴11上,并具有与第一台肩部12的第一倾斜表面13配合的第二倾斜表面23。在初始安装状态下,第一台肩部12的第一倾斜表面13可与导向件2的第二倾斜表面23彼此贴靠,从而形成形状配合的连接。换言之,第一倾斜表面13和第二倾斜表面23均可构造成围绕驱动轴11的螺旋形, 且二者具有相同的螺旋升角。导向件2还被构造为能够随着驱动部件1一起转动,或者能够相对于驱动部件1以与驱动部件1的转动方向R相反的方向沿着第一倾斜表面13运动。
收料轮4套设于导向件2的外侧,其与导向件2之间的连接被构造成不可相对转动地连接,其中不可相对转动地连接是指在驱动部件1的周向方向不可相对转动,在轴向方向上能够相对运动地连接。因此,在导向件2的带动下,收料轮4能够与导向件2一起在驱动部件1的驱动下随着驱动部件1转动,或者相对于驱动部件1以与驱动部件1的转动方向R相反的方向转动以实现运动补偿。
弹性体3设置于导向件2与收料轮4之间,以便向导向件2施加预载荷,从而使得第二倾斜表面23压靠到第一倾斜表面13上。当弹性体3施加于导向件2上的预载荷的大小发生变化时,导向件2的第二倾斜表面23与驱动部件1的第一倾斜表面13间的摩擦力也将相应地发生变化。
优选地,导向件2具有围绕驱动轴11设置的收纳部21,以便将弹性体3更好地收纳在导向件2与收料轮4之间。具体地,弹性体3为压缩弹簧,其套设于驱动轴11上。应当理解的是,还可设置任何其他适宜形式的弹性体3。
在本实施例中,参考图3,驱动部件1包括位于其底部的驱动底盘110、用于安装定位其他部件的驱动轴11、用于引导配合导向件2的第一台肩部12和用于支撑收料轮4的台阶部17。驱动轴11与驱动底盘110一体成形,直立地设置在驱动底盘110上,且沿轴向向远离驱动底盘110的方向延伸。在驱动轴11的顶部,绕驱动轴11的外周设有径向突出的突筋部15。从突筋部15的顶部至底部,该突筋部15具有在轴向方向上沿径向向外倾斜的斜面,以便将收料轮4引导安装至突筋部15的底面。同时,该突筋部15的最大外周直径略大于收料轮4的通孔41,使得收料轮4在安装完成后其顶部抵止于该突筋部15的底面,从而无法沿轴向方向向远离所述驱动部件1的底部的方向运动。
优选地,驱动轴11远离驱动底盘110的一端还可设有平行于轴向的平面侧切部16,该平面侧切部16沿轴向穿过突筋部15,以增大收料轮4与驱动轴11的安装空间,从而便于将收料轮14安装于突筋部15的底侧。
优选地,驱动部件1的驱动底盘110被构造为齿轮。此时,驱动部件1包括位于底部的齿轮和设置于齿轮中央的驱动轴11。驱动部件1能够通过齿轮的齿牙与外部齿轮、齿条啮合,从而在动力源的驱动下转动。可替代地,驱动底盘110被构造为带轮,此时带轮通过其上的皮带与外部传动部件及动力源配合,从而在动力源的驱动下进行转动。
驱动底盘110上还设置有绕驱动轴11形成的环形的台阶部17,且台阶部17从驱动底盘110的顶表面突出。在卷绕装置100的初步安装状态下,台阶部17与收料轮4的底壁接触以定位支撑收料轮4,并且能够与突筋部15配合限制收料轮4的轴向运动。优选地,台阶部17的外径小于收料轮4的底部外径。
驱动部件1的驱动底盘110上还设置有第一台肩部12,在第一台肩部12的顶部表面形成有第一倾斜表面13。其中,参考图3,第一倾斜表面13的法向量Fn与驱动部件1的转动方向R的夹角α为锐角,即,沿着转动方向R,第一倾斜表面与驱动底盘110的底面的距离逐渐减小。通过使得第一倾斜表面13的法向量Fn与驱动部件1的转动方向的夹角α为锐角,在一定条件下,导向件2能够相对于驱动部件1沿第一倾斜表面13以与转动方向R相反的方向运动。
第一台肩部12上可以仅设置一个第一倾斜表面13,此时,第一倾斜表面 13设置在第一台肩部12的绕驱动轴11的整个圆周上。当仅设置一个第一倾斜表面13时,由于第一倾斜表面13的周长长度足够长,在卷绕装置100转动补偿过程中,导向件2相对于驱动部件1沿第一倾斜表面13的运动所需的长度能够得到满足。同时,由于第一倾斜表面13的周长长度足够长,导向件2沿第一倾斜表面13的运动能够保证是连续的,使得导向件2的第二倾斜表面23不会完全离开第一倾斜表面13,从而避免导向件2在运动过程中的弹跳,进而避免卷绕装置100在卷绕料带的过程中出现震动和噪音。
在第一台肩部12上也可以设置多个第一倾斜表面13,具体数量可以根据实际需求选择确定。当设置有多个第一倾斜表面13时,其均匀分布在第一台肩部12绕驱动轴11的整个圆周上,第一台肩部12的顶面在周向上呈锯齿状。多个第一倾斜表面13在第一台肩部12形成的圆周上可以彼此相继地均匀分布,也可以通过第一台肩部12在各第一倾斜表面13之间的周向缺口而以间隔一定距离的方式均匀分布,具体分布形式可以根据实际需求选择确定。
优选地,设置有两个第一倾斜表面13且其在第一台肩部12形成的圆周上彼此相继地均匀分布,从而使得第一倾斜表面13的长度足够长,进而使得在卷绕装置100转动补偿过程中,导向件2沿第一倾斜表面13运动所需的长度能够得到满足,从而避免导向件2的弹跳,进而避免卷绕装置100在卷绕料带的过程中出现震动和噪音。
优选地,第一倾斜表面13设置成能够与第二倾斜表面23配合,并且每个第一倾斜表面13沿周向的长度等于或者大于每个第二倾斜表面23沿周向的长度。因此,在卷绕装置100卷绕料带的过程中,驱动部件1的第一倾斜表面13可保持与导向件2的第二倾斜表面23接触。
在本实施例中,参考图3,驱动部件1包括一个第一台肩部12,其围绕驱动轴11形成一个圆周。并且,第一台肩部12上设置有两个第一倾斜表面13,各第一倾斜表面13在第一台肩部12绕驱动轴11的圆周上彼此相继地均匀分布,且每个第一倾斜表面13的法向量Fn与驱动部件1的运动方向R的夹角α为锐角。
通过设置两个第一倾斜表面13,使得各第一倾斜表面13的长度足够长,从而使得在卷绕装置100卷绕料带过程中导向件2在一定条件下能够相对于驱动部件1运动,由此保证卷绕装置100在收料轮4有效卷绕直径增大时能够进行运动补偿。同时,由于各第一倾斜表面13的长度足够长,使得导向件2的第二倾斜表面23保持与第一倾斜表面13接触而不会完全离开第一倾斜表面13,由此避免了导向件2因第二倾斜表面23未与驱动部件1的第一倾斜表面13接触而形成的弹跳,从而防止该卷绕装置100在卷绕料带的过程中产生震动和较大的噪音。
特别是,在设置彼此相继且均匀分布的两个第一倾斜表面13的情况下,第一台肩部22上相邻的两个第一倾斜表面13之间存在一桥接面14,该桥接面14优选地在平行于或穿过驱动轴11的轴线的轴向表面延伸。
在导向件2与桥接面14接触时,桥接面14形成阻止导向件2相对于驱动部件1沿转动方向R继续转动的第一台肩止挡部,此时导向件2卡止于驱动部件1的止挡位置处,并且在驱动部件1的驱动下能够与驱动部件1一起转动。
进一步地,导向件2与驱动部件1一起转动时的卡止方式为,根据弹性体3施加于导向件2上的预载荷,导向件2受到沿第一倾斜表面13朝向驱动部件1的底部的力以及在驱动部件1和导向件2的倾斜表面间形成阻止导向件2相对 于驱动部件1运动的摩擦力,由此形成导向件2沿转动方向R相对于驱动部件1转动的运动趋势。此时,由于导向件2与桥接面14接触,桥接面14将形成阻止导向件2相对于驱动部件1运动的止挡,也即桥接面14形成第一台肩止挡部。该第一台肩止挡部能够与导向件2配合以阻止导向件2以与转动方向R相同的方向相对于驱动部件进一步转动。
在卷绕装置100卷绕料带的过程中,在料带张力的作用下,导向件2还可沿第一倾斜表面13运动,使得导向件2相对于驱动部件1以与驱动部件1的转动方向R相反的方向转动。
参考图2和图4,导向件2具有围绕驱动轴11设置的用于收纳弹性体3的收纳部21,收纳部21形成为具有底部的第一筒状结构。并且,收纳部21的底部形成直径大于驱动轴11直径的通孔26,从而使得导向件2能够通过通孔26插入驱动轴11,由此通过通孔26而套设在驱动轴11上。同时,收纳部21的筒内径大于弹性体3的外径,收纳部21底部的通孔26的直径小于弹性体3的外径,使得能够将弹性体3收纳至收纳部21中,从而便于弹性体3向导向件2施加轴向的预载荷。
在弹性体3的作用下,例如挤压下,第二倾斜表面23与第一倾斜表面13贴合。同时,导向件2与驱动部件1的桥接面14的接触或者贴合,并且卡止于第一台肩部12,由此将导向件2安装于驱动部件1的顶部。优选地,当弹性体3为压缩弹簧时,其外径为通孔26直径的1.5倍。
在收纳部21的外周上设置有缺口部25,缺口部25沿径向方向延伸并沿轴向方向贯穿收纳部21的侧壁,导向件2通过缺口部25与收料轮4形成不可相对转动地连接。可根据实际需求来选择具体缺口部25的数量。优选地,缺口部25的数量为两个。更加优选地,多个缺口部25在收纳部21的外周上沿周向均匀分布。
在收纳部21下侧形成有第二台肩部22,第二台肩部22的倾斜表面的数量和位置与第一倾斜表面13一一对应。第二倾斜表面23形成第二台肩部22的底部端表面,其形状与第一倾斜表面13匹配,即第二倾斜表面23与第一倾斜表面13的数量、平面形状和倾斜角度(螺旋升角)相同。当导向件2仅具有一个第二台肩部22时,第二倾斜表面23在第二台肩部22的绕驱动轴的整个圆周上形成。
当导向件2具有多个第二台肩部22时,多个台肩部22绕驱动轴11形成一个圆周,且在该圆周上均匀分布。多个第二台肩部22在其形成的圆周上可以彼此相继地均匀分布,也可以通过第二台肩部22的周向缺口241而间隔一定距离地均匀分布,具体分布形式可以根据实际需求选择确定。当第二台肩部22设置有多个时,每个第二台肩部22在其圆周上的弧长可以小于第一倾斜表面13的弧长。
在本实施例中,参考图4,导向件2具有两个第二台肩部22,每个第二台肩部22均具有一个第二倾斜表面23。该两个第二台肩部22绕收纳部21的中心轴线形成一圆周,且在该圆周上通过彼此间的周向缺口241而间隔一定距离地方式均匀分布。第二倾斜表面23形成于第二台肩部22的底表面,相应地也具有两个。在卷绕装置100的初始安装状态下,导向件2通过其第二倾斜表面23与驱动部件1的第一倾斜表面13的接触而被安装于驱动部件1的顶部。
在相邻的第二倾斜表面23之间形成有在初始安装状态下能够平行于桥接面14的竖向表面24,该竖向表面24与桥接面14的形状相配。初始安装状态下, 竖向表面24与桥接面14贴合,从而形成限制导向件2的进一步相对于驱动部件1沿着转动方向R转动的第二台肩止挡部。在导向件2随驱动部件1转动的过程中,通过第一台肩止挡部和第二台肩止挡部的相互卡止,在弹性体3的作用下,导向部2能够在驱动部件1的驱动下随着驱动部件1一起转动。
参考图5和图6,收料轮4被构造为具有顶部的第二筒状结构,在其顶部设有通孔41,通孔41的直径大于驱动轴11远离驱动底盘110的一端的轴径,从而使得收料轮4能够通过通孔41而穿过驱动轴11,进而将收料轮4安装于驱动轴11上。收料轮4的筒壁内表面设有径向延伸的多个突起部47,该多个突起部47在收料轮4的内表面沿周向方向上分布,优选地均匀分布。优选地,收料轮4的多个突起部47与导向件2的多个缺口部25的位置和数量一一对应。
可替代性地,突起部47与缺口部25的设置位置可互换,即缺口部25可设置于收料轮4的内表面处,突起部47可设置于导向件2的外周上。
在收料轮4内表面的周向方向上,突起部47的尺寸等于缺口部25的尺寸,从而能够将突起部47插入缺口部25中,使得收料轮4能够通过该突起部47与导向件2的缺口部25的接合而套设于导向件2的径向外侧,并且形成不可相对转动地连接。由于收料轮内侧的突起部47和导向件2外侧的缺口部25相互接合,同时收料轮4的轴向运动受到限制,收料轮4仅仅能够转动运动。在导向件2通过其第二倾斜表面23沿着第一倾斜表面13运动时,导向件2还能够通过其上的缺口部25沿着突起部47做轴向运动,从而带动收料轮4仅做转动运动。
参考图5,在收料轮4外周上还设置有轴向延伸的缺切部43,并沿该缺切部43的最外侧圆周直立设置有料带生根部44,料带在其初始位置形成一个套圈状的套环,该套环的形状与料带生根部44配合,料带通过套环套设于料带生根部44上而固定于收料轮4上。
图7示出了在装配状态下的卷绕装置。参考图7,卷绕装置100装配完成后,导向件2、弹性体3和收料轮4依次安装或者套设在驱动部件1的驱动轴11上。同时,收料轮4的顶部抵止在驱动轴11的突筋部15靠近收料轮4的底面,使得其无法沿轴向方向运动。弹性体3,例如压缩弹簧,设置在导向件2的收纳部21中,并位于收料轮4与导向件2之间,从而施加沿轴向朝向驱动部底盘110的预载荷于导向件2上以沿轴向挤压导向件2。由于弹性体3的预载荷,第二倾斜表面23贴合于第一倾斜表面13。同时,收料轮4内表面的突起部47插入导向件2上对应位置处的缺口部25,收料轮4与导向件2由此转动地锁定,从而使得收料轮4能够随导向件2在驱动部件1的带动下转动。
初始状态下,料带缠绕在收料轮4上,给料构件每次恒定角度给进料带。当被卷绕的料带所承受的张力未超过预定阈值时,参考图8,在弹性体3的轴向挤压下,导向件2的竖向表面24与桥接面14相互贴合。此时,收料装置处于正常工作状态下,即收料轮随驱动部件1一起转动。
当收料轮4卷完一圈料带后,收料轮4的有效卷绕直径对应增加,由此造成收料轮4的线速度增大,进而导致收料轮4单次转动所卷绕的料带长度增大。此时,由于卷绕的料带长度增大,而给料构件每次转动给进的料带长度恒定,在卷绕装置100与给药装置之间的料带的张力增大。
当张力增大到预定值时,基于料带所承受的张力大小,参考图9,导向件2能够克服由于弹性体3的预载荷Ft而生成的与第一倾斜表面13之间的摩擦力Ff和预载荷Ft沿第一倾斜表面朝向驱动部件1底部的分量力Fd,从而与收料轮 4一起相对于驱动部件1以与转动方向R相反的方向转动,同时导向件2沿着第一倾斜表面13向上运动。其中摩擦力Ff等于第一倾斜表面13与第二倾斜表面23的摩擦因子与预载荷Ft在第一倾斜表面13的法向量上的分量的乘积。
此时,卷绕装置100处于运动补偿工作状态。具体地,与导向件2不可相对转动地连接的收料轮4在导向件2的带动下相对于驱动部件1沿着与驱动部件1的转动方向R相反的方向转动,即收料轮4将由于张力作用而相对于驱动部件1反向转动,由此实现对收料轮4的运动补偿。但是,此时,收料轮4仍然在卷绕料带,即此时收料轮4和导向件2相对于地面的转动运动仍然为沿着驱动部件1的转动方向R转动。因此,基于料带所承受的张力大小,该用于料带的卷绕装置能够克服导向件2与第一台肩部12之间的摩擦力和预载荷生成的沿第一倾斜表面13的分量,使得导向件2的第二倾斜表面23与驱动部件1的第一倾斜表面13之间能够相对运动,进而实现对收料轮4的运动补偿。
在本公开内容第一方面的第二实施例中也提供了一种用于料带的卷绕装置100,第二实施例中的卷绕装置100与第一实施例中的卷绕装置100的区别仅在于驱动轴与驱动底盘是分体形成的。具体地,参考图10,该分体形成的驱动部件1与第一实施例中基本相同,都包括驱动轴111、第一台肩部121和台阶部171。不同之处仅在于,第二实施例中的驱动轴111可拆卸地安装于驱动部件1的驱动底盘112中央。
参考图10至图13,驱动部件1包括驱动轴111和驱动底盘112,在驱动底盘112的中央设置有贯穿的通孔161,通孔161处的内表面设置有多个沿径向延伸轴向贯穿的安装槽181,安装槽181在通孔161的内表面沿周向均匀地分布。优选地,设置有两个安装槽181。同时,驱动轴111被构造为台阶轴,其靠近驱动底盘112的一端的轴162的直径小于通孔161的直径,从而能够插入通孔161中。而且,轴162的靠近驱动底盘112的一端设置有均匀分布的多个卡扣182,各卡扣182沿着轴162的外周均匀分布。优选地,各卡扣182的位置和数量与安装槽181一一对应。而且,在周向方向上,卡扣182的尺寸小于安装槽181的尺寸,使得各卡扣182能够通过对应位置处的安装槽181,从而能够与轴162一同插入驱动部件1的通孔161中。
同时,在驱动部件1的底部中央的下表面形成有直径大于通孔161的孔183,孔183、通孔161与安装槽181共同形成位于驱动底盘112内部的弧形的凸块184,在凸块184的底面形成有能够接合卡止卡扣182的卡槽185。卡槽185的中心线与安装槽181的中心轴线在空间内成一定角度。优选地,该角度为90度。
具体地,将驱动轴111卡止固定于驱动底盘112的过程包括,将轴162和卡扣182插入驱动底盘112的通孔161后,再将驱动轴111转动一定角度,使得在孔183内卡扣182到达卡槽185的对应位置处,随后沿轴向方向提升驱动轴111,以将卡扣182挤压进入卡槽185,从而使得卡扣182能够如图13所示被卡接固定于卡槽185中,从而使得安装固定后的驱动轴111随驱动部件1同步转动运动。此外,优选地,驱动轴111上的突筋部151被构造为具有平坦下表面的圆环状。更加优选地,收料轮4顶部与突筋部151接触的表面被设置为平面,以使得收料轮4顶面与突筋部151之间的摩擦为平面摩擦,从而减小收料轮4与驱动轴111之间的摩擦力。
根据本公开内容的第二方面,还提供了一种如图14所示的药物分配器200。参考图14至图16,该药剂分配器200包括外壳201、盖体202、吸嘴203以及设置在壳体内部的进气歧管210和药剂分配装置220。其中,进气歧管210安装 于药剂分配装置220的特定位置上,盖体202与药剂分配装置220机械耦合,因此用户能够通过打开盖体202来触发壳体内部的药剂分配装置220的运动,使得盖体202完全打开时,药剂分配装置220在正常工作状态下能够将药剂、如粉末状药剂分配至进气歧管210的气道对应位置处,从而使得用户能够通过吸嘴203经由进气歧管210吸入药剂粉末。
示例性地,盖体202经传动机构(未示出)与药剂分配装置220机械耦合,通过盖体202的转动能够向药剂分配装置220输入驱动动力。而且,进气歧管210安装于位于药剂分配装置220的特定位置处的歧管安装部211上,从而使得在正常工作状态下药带经药剂分配装置220分配给药后,药带上的暴露于空气中的药剂能够与进气歧管210的气道相对。
在下文中将结合药带230对药剂分配装置220的具体构造和药剂分配过程进行描述,其中药带230包括盖片带231、基片带232和在二者之间能够收纳粉末状药剂的药剂容纳部233,而且药带230沿长度方向的端部处的盖片带231和基片带232处于彼此分离的状态。
参考图15至图16,药剂分配装置220包括给药装置240、剥片装置(未示出)、基片带卷收装置250和卷绕装置100,其中卷绕装置100可以为根据本公开内容第一方面的各项实施例所描述的用于料带的卷绕装置100,其在药剂分配装置220中被构造为卷绕盖片带231。
给药装置240被构造为分配药剂。具体地,给药装置240包括药带容纳腔241和药带安装轴242,药带230经卷绕后能够被容纳于药带容纳腔241中,同时安装固定于药带安装轴242上,从而能够在外力作用或者卷绕装置100的拉力作用下绕药带安装轴242运动,以实现药带230在壳体内的运动和药剂的分配动作。剥离装置被构造为在气道附近剥离药带230。
基片带卷收装置250被构造为卷收经剥离后的基片带232。基片带卷收装置250包括基片带容纳腔251和卷绕轴252,基片带232的端部固定于卷绕轴252的安装部上,且经剥离后的基片带232能够在卷绕轴252的转动作用下被卷收于卷绕轴252上,从而被容纳于基片带容纳腔251中。
卷绕装置100被构造为卷绕经剥离后的盖片带232,卷绕装置100的具体构造和工作过程如本公开内容第一方面的各实施例中的卷绕装置100所述。参考图15,盖片带232的处于分离状态的端部固定于卷绕装置100的收料轮4的料带生根部43上,经收料轮4的转动作用而被卷绕于收料轮4的外表面上。
并且,收料轮4卷绕被剥离的盖片带232的过程中,还能够相对于驱动部件1转动以实现运动补偿,从而保证收料轮4转动一次所卷绕的盖片带232的长度一致,进而保证药剂容纳腔与进气歧管210的相对位置不变。因此,药剂分配器200能够通过盖体202、给药装置240、卷绕装置100以及基片带卷绕装置250的转动实现药剂的分配以及上述部件和装置的相互作用实现药剂的可获得。
当盖体202转动时,药剂分配装置220被触发开始药剂的分配工作。当药剂分配装置220被触发时,参考图15,给药装置240的分度轮243开始转动,从而带动药带230绕药带安装轴242旋转,使得未卷绕至药带安装轴242的药带230在壳体内朝向进气歧管210的气道方向运动。同时,卷绕装置100将跟随给药装置240同步转动,基片带卷收装置250也同步进行转动。当卷曲的药带230的盖片带231和基片带232经过给药装置230的分度轮243和剥片装置而被剥离分开时,在卷绕装置100的收料轮4转动而形成的拉力作用下,盖片 带231一经剥离开来即被卷绕到卷绕装置100的收料轮4上。
同时,经剥离作用分离的基片带232被卷曲到基片带卷绕装置250的卷绕轴252上。此时,容纳于药剂收纳腔233中的药剂通过剥离后形成的开放开口而被患者通过进气歧管210的气道和吸嘴203吸入。总的来说,是给药装置230、卷绕装置100以及基带片卷绕装置240的同步配合转动实现了药剂分配及药剂的可获得。下面将结合图16具体描述实现给药装置230、卷绕装置100以及基片带装置240间的同步配合转动的齿轮传动系统260。
参考图16,该齿轮传动系统260包括触发齿轮261、给药齿轮262、第一传动齿轮263、驱动齿轮264和基片带卷绕齿轮265,其中驱动齿轮264可以为上述图3或者图10所例示的形成驱动底盘110或驱动底盘112的齿轮,即此时图3所示的驱动部件1的驱动底盘110被构造为齿轮或者图10所示的驱动部件1的驱动底盘112被构造为齿轮。具体地,该齿轮传动系统260的动力传动过程将在下文展开详述。
齿轮传动系统260通过触发齿轮261经由传动机构(未示出)与盖体202机械耦合,能够在盖体202的转动触发下接收输入驱动动力。给药齿轮262与触发齿轮261啮合,能够在触发齿轮261转动时,在触发齿轮261的驱动下同时转动。而且,给药装置240中的分度轮243固定于给药齿轮262,分度轮243随给药齿轮262转动,从而使得分度轮243也在触发齿轮261的驱动下同步转动以驱动药带230进行药剂分配。
同时,基片带卷绕齿轮264与第一传动齿轮263啮合,第一传动齿轮163与触发齿轮261啮合,即基片带卷绕齿轮264经由第一传动齿轮263而与触发齿轮261配合,使得基片带卷绕齿轮264能够经由第一传动齿轮163而与触发齿轮261同步转动。同时,基片带卷绕轴251设置于基片带卷绕齿轮264上,使得基片带卷绕轴251能够随基片带卷绕齿轮264转动以卷绕经剥离后的基片带232,由此实现基片带卷绕装置250与给药装置240的同步转动。
驱动齿轮265与给药齿轮262啮合,能够在给药齿轮262的驱动下同步转动,从而向卷绕装置100输入转动运动,使得卷绕装置100在驱动齿轮265的驱动下卷绕经剥离后的盖片带231。当收料轮4的有效卷绕直径增大时,如本公开内容第一方面的各实施例所述,收料轮4能够相对于驱动齿轮265旋转,从而补偿收料轮4由于最外圈直径增大在驱动齿轮265每次转动时可能额外卷绕的盖片带231长度,确保收料轮4在驱动齿轮265每次转动时所卷绕的盖片带231的长度一致,从而避免由于收料轮4的拉力而改变暴露于空气中的药剂的实际位置,进而避免该药剂与进气歧管210的气道位置发生错位从而使得用户无法获得药剂。同时,由于收料轮4每次转动所卷绕的盖片带231的长度一致。经收料轮4提供给药带230的推进张力或者收料轮4与给药装置240之间的药带230的张力基本恒定,有效地避免了药带230由于张力过大而断裂。
本公开不限于上述实施方式,并且可以在不脱离本公开的范围的情况下适当地改变。例如,在上述实施方式中,已经描述了第二倾斜表面设置在收料轮上,导向件也可以与收料轮一体成形。从上述公开内容中,可以明显看出本公开内容的方案能以多种方式变化这些变化不应被认为是脱离本公开的精神和范围,并且本领域技术人员可作出的所有这些修改都旨在包括在所附权利要求的范围内。
