Description

一种用于安瓿瓶的夹持切瓶机构 技术领域
本发明涉及一种医疗设备技术领域，特别是一种用于安瓿瓶的夹持切瓶机构。
背景技术
安瓿瓶1是用于盛装药液的小型玻璃容器，如图1所述，其结构包括瓶身12、瓶头11，以及位于瓶身12、瓶头11之间过渡部分的成凹陷部分的瓶颈13，该安瓿瓶1的容量一般为1～25ml，一般用于注射用药液。
目前，在配制安瓿瓶的药液时，一般采取首先对安瓿瓶瓶体进行消毒，然后直接通过人工或钳子将瓶头敲断；或者先采用划刀对安瓿瓶瓶颈进行划线，再消毒，然后再用手或其他工具将安瓿瓶上部分折断，最后用针管把安瓿瓶中的药品抽到母液袋中。这两种方式，都是利用人工来对安瓿瓶进行折断，其不足在于，人工持器械进行敲击容易造成瓶头破碎不均匀、容易敲碎瓶体，同时瓶头断裂碎片对安瓿瓶药液容易造成污染。
为此，现在出现有机械化的配制安瓿瓶药液的装置，但是针对安瓿瓶夹持和对安瓿瓶的切割，均是分别采用了独立的两个不同结构并分别进行控制，这两个结构聚合在配药装置上，所占用的体积较大，所需要的能耗较多，例如夹持机构和切割机构均采用电机来控制移动，成本较高。
发明内容
本发明的发明目的在于：针对现有机械化安瓿瓶配药装置中，针对安瓿瓶夹持和安瓿瓶切割，采用了不同的两套结构，造成的所占体积较大、能耗较多以及成本较高的上述问题，提供一种用于安瓿瓶的夹持切瓶机构，该机构能够将安瓿瓶夹紧，同时还可以通过在切割件上对安瓿瓶切割，结构简单、紧凑， 大大节约了体积，降低了成本。
为了实现上述目的，本发明采用的技术方案为：
一种用于安瓿瓶的夹持切瓶机构，包括底座，所述底座上设有两个支架，每个所述支架上设有一个夹板和一个切割件；两个所述夹板相对设置构成夹持部件，同时两个所述夹板间距可调并与安瓿瓶的瓶身适配；两个所述切割件相对设置构成切瓶部件，同时两个所述切割件间距可调并与安瓿瓶的瓶颈适配。
该用于安瓿瓶的夹持切瓶机构，包括位于底座上的两个支架，每个支架上均设有一个夹板和切割件，两个支架上的两个夹板构成夹持部件且间距可调，两个支架上的两个切割件构成切瓶部件且间距可调，其中夹持部件用于配药准备阶段时对安瓿瓶瓶身或瓶颈的夹持，还可用于对安瓿瓶断瓶时的夹持，切瓶部件用于安瓿瓶折断时在安瓿瓶瓶颈上切割形成两条划痕，便于折断。
相对现有的安瓿瓶配药装置将夹持和切割分开设置而言，本机构将夹持部件和切割部件的功能均集成在一个底座上的两个支架上，通过两个支架上的两个夹板和切割件的可同时相对移动，能够分别能够对安瓿瓶进行夹紧和对安瓿瓶瓶颈进行切割，该夹持切瓶机构的结构简单、紧凑，大大节约了体积，节约了能源，降低了成本。
优选地，每个所述支架上所述夹板和切割件均能够相对对应支架沿直线滑动。

优选地，每个所述支架上的所述夹板和切割件通过一个滑块滑动连接在所述支架上，所述滑块与所述支架之间设有用于将所述滑块回复至初始位置的回复部件。

优选地，每个所述支架与滑块之间设置的回复部件包括至少一个扭簧。
选用扭簧来作为支架和滑块之间的回复部件，相对于常用的普通螺旋弹簧而言，扭簧对滑块和支架相对位移的行程更长，因为普通螺旋弹簧被压缩时，当螺距为0，便无法进一步被压缩，因此行程较短；而扭簧的行程相对较长。
优选地，每个所述支架与滑块之间设置的回复部件包括至少一个双扭簧，每个所述双扭簧包括螺旋形的扭簧本体、两个固定臂和一个活动臂，所述支架上设有与所述扭簧本体适配的支柱，所述固定臂连接在所述支架上，所述活动臂连接在所述滑块上。
采用双扭簧可以提高滑块与支架之间回复力，能够提供对安瓿瓶更大的夹持力和切割力，提高该夹持切瓶机构对安瓿瓶夹持和切瓶的可靠性。
优选地，每个所述支架与滑块之间设置的回复部件包括两个双扭簧，两个所述双扭簧分别对称设置在对应所述支架上的两个支柱上。
每个支架和滑块之间采用两个相互对称的双扭簧，能够提高滑块与支架发生相对位移时的夹持部件和切瓶部件的稳定性。
优选地，所述支架上设有滑轨，所述滑块上设有与所述滑轨适配的滑槽。
优选地，所述夹板和切割件均为可拆卸连接在所述滑块上。
优选地，两个所述夹板相对的内侧设有与安瓿瓶适配的弧形凹槽。
优选地，所述切割件为砂轮，所述砂轮固定或旋转连接在所述滑块上。
由于扭簧所提供的两个砂轮对安瓿瓶的夹紧力较大，该砂轮可选用直接固定或旋转连接在滑块上，不用使用电机驱动砂轮，当安瓿瓶穿过两个砂轮时， 其切割力也较大，也能够满足安瓿瓶实际切割断瓶的要求，节约了能耗。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明所述一种用于安瓿瓶的夹持切瓶机构，包括位于底座上的两个支架，每个支架上均设有一个夹板和切割件，两个支架上的两个夹板构成夹持部件且间距可调，两个支架上的两个切割件构成切瓶部件且间距可调，其中夹持部件用于配药准备阶段时对安瓿瓶瓶身或瓶颈的夹持，还可用于对安瓿瓶断瓶时的夹持，切瓶部件用于安瓿瓶折断时在安瓿瓶瓶颈上切割形成两条划痕，便于折断；相对现有的安瓿瓶配药装置将夹持和切割分开设置而言，本机构将夹持部件和切割部件的功能均集成在一个底座上的两个支架上，通过两个支架上的两个夹板和切割件的可同时相对移动，能够分别能够对安瓿瓶进行夹紧和对安瓿瓶瓶颈进行切割，该夹持切瓶机构的结构简单、紧凑，大大节约了体积，节约了能源，降低了成本；

具体实施方式
下面结合附图，对本发明作详细的说明。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
如图2-5所示，一种用于安瓿瓶1的夹持切瓶机构，包括底座(图中未展示)，该底座上设有两个支架2，每个支架2上设有一个夹板5和一个切割件6；两个夹板5相对设置构成夹持部件，同时两个夹板5间距可调并与安瓿瓶1的瓶身 12适配；两个切割件6相对设置构成切瓶部件，同时两个切割件6间距可调并与安瓿瓶1的瓶颈13适配。
如图5所示，其中每个支架2上夹板5和切割件6均能够相对对应支架2沿直线滑动，具体的，每个支架2上的夹板5和切割件6通过一个滑块4滑动连接在支架2上，滑块4与支架2之间设有用于将滑块4回复至初始位置的回复部件7。图5中实线箭头即为滑块4上的夹持部件和切瓶部件移动后的示意图，虚线箭头为回复部件7发生弹性回复时的示意图；如图6为该夹持部件夹持安瓿瓶1时的机构示意图，图7为该切瓶部件切割安瓿瓶1时的机构示意图。
该支架2上的夹板5和切割件6集成，并可同时相对该支架2做直线滑动，通过控制夹板5或者切割件6任一一个相对支架2直线滑动，即可同时实现对夹板5和切割件6的移动，有效节约了能耗，移动和控制均很方便。另外，通过回复部件7连接滑块4和支架2，不用电机驱动滑块4的移动，便能够形成对安瓿瓶1的自适应夹持和切割效果，使该夹持切瓶机构的结构更加简单化、紧凑化和轻量化，也节约了能耗。
本实施例中，如图8、9所示，在每个支架2与滑块4之间设置的回复部件7采用了两个双扭簧，两个双扭簧分别对称设置在对应支架2上的两个支柱21上。每个双扭簧为常见的扭簧结构，即每个双扭簧包括螺旋形的扭簧本体71，分为上下各两节，每个扭簧本体71包括一个固定臂72和一个活动臂73，两个活动臂73相互连接形成一体，其中两个固定臂72连接在支架2上，而活动臂73连接在滑块4上。
选用扭簧来作为支架2和滑块4之间的回复部件7，相对于常用的普通螺旋弹簧而言，扭簧对滑块4和支架2相对位移的行程更长。而采用双扭簧可以提高滑块4与支架2之间回复力，能够提供对安瓿瓶1更大的夹持力和切割力，提高该夹持切瓶机构对安瓿瓶1夹持和切瓶的可靠性。由于在每个支架2和滑块4之间采用两个相互对称的双扭簧，能够提高滑块4与支架2发生相对位移 时的夹持部件和切瓶部件的稳定性。
上述的支架2上设有两个相对的侧板3，如图5所示，每个侧板3上均设有滑轨31，滑块4的两端设有与滑轨31适配的两个滑槽41。该夹板5和切割件6均是通过螺栓可拆卸连接在滑块4上。两个夹板5相对的内侧设有与安瓿瓶1适配的弧形凹槽51，另外，切割件6选用常用的砂轮，该砂轮采用固定或旋转方式连接在滑块4上，砂轮并不需要电机提供动力旋转。因为考虑到双扭簧所提供的两个砂轮对安瓿瓶1的夹紧力较大，该砂轮可选用直接固定或旋转连接在滑块4上，不用使用电机驱动砂轮，当安瓿瓶1穿过两个砂轮时，其切割力也较大，也能够满足安瓿瓶1实际切割断瓶的要求，节约了能耗。
如图5-7所示，使用该夹持切瓶机构对安瓿瓶1进行夹紧或切瓶时，由于该机构包括了位于底座上的两个支架2，每个支架2上均设有一个夹板5和切割件6，两个支架2上的两个夹板5构成夹持部件且间距可调，两个支架2上的两个切割件6构成切瓶部件且间距可调，其中夹持部件用于配药准备阶段时对安瓿瓶1瓶身12或瓶颈13的夹持，还可用于对安瓿瓶1断瓶时的夹持，切瓶部件用于安瓿瓶1折断时在安瓿瓶1瓶颈13上切割形成两条划痕，便于折断。
相对现有的安瓿瓶1配药装置将夹持和切割分开设置而言，本机构将夹持部件和切割部件的功能均集成在一个底座上的两个支架2上，通过两个支架2上的两个夹板5和切割件6的可同时相对移动，能够分别能够对安瓿瓶1进行夹紧和对安瓿瓶1瓶颈13进行切割，该夹持切瓶机构的结构简单、紧凑，大大节约了体积，节约了能源，降低了成本。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
