具体实施方式
为更进一步阐述本实用新型为达成上述目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本实用新型的具体实施方式、结构、特征及其功效进行细说明。应当理解，本实用新型所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
如图1所示，图1是本实用新型弹射功能的半自动注射装置较佳实施例的架构示意图。
所述弹射功能的半自动注射装置1包括移动装置10、捆绑装置20及滑轨30。所述移动装置10设置于滑轨30上，该移动装置10在滑轨上滑动。
当所述弹射功能的半自动注射装置1佩戴于人体部位（例如，手掌、手臂或手腕处）上时，所述捆绑装置20捆绑所述人体部位，所述捆绑装置20减缓所述人体部位中静脉血管内血液的流通，从而使得所述静脉血管凸起，如此一来，可以很清晰地看到鼓起的静脉血管。在本实施例中，所述捆绑装置20可以是，但不限于，封闭式橡皮筋、封闭式绷带或封闭式充气圈等。
所述移动装置10的上表面设置有注射器11、弹射装置12及角度调整装置13。所述注射器11与所述弹射装置12及角度调整装置13连接。所述注射器11还与药液容器3连接。所述药液容器3为装药液的吊瓶。一般而言，所述药液容器3比所述注射器11放置的位置高于一定的预设高度（例如，一米）。需要说明的是，所述药液容器3并没有安装于所述弹射功能的半自动注射装置1上，而是与所述弹射功能的半自动注射装置1分离。
如图2所示，图2是本实用新型弹射功能的半自动注射装置中注射器的较佳实施例的平面结构示意图。
所述注射器11包括针头110、针筒111、挡板112及输液软管113。所述针头110固定于所述针筒111的前端，所述输液软管113穿过所述针筒111内部连接到所述针头110，进一步地，所述输液软管113还与所述药液容器3连接。所述针筒111的末端设置有挡板112，通过推动所述挡板112可以移动所述针筒111，进而移动所述针头110。需要说明的是，所述针头110与所述针筒111之间为可拆卸式的结构，以及所述输液软管113与所述针筒111之间为可拆卸式的结构。也就是说，所述针头110及所述输液软管113可以从所述针筒111中取出，以便于更换。所述弹射装置12内置弹簧的装置。所述弹射装置12包括按钮（未示出），当患者或医务人员按下按钮时，所述弹射装置12产生弹射力作用于所述挡板112上，使得所述针筒111弹射出去将针头110插入血管中以完成注射。
所述针头110用于刺破所需注射的静脉血管并进入该静脉血管。当所述针头110进入所述静脉血管后，患者或医务人员松开所述捆绑装置30，以停止对所述人体部位捆绑（即增大所述圆圈的半径）。
所述针筒111用于固定所述针头110，当所述针筒111移动时，所述针头110也随着所述针筒111移动。换句话说，通过移动所述针筒111，使得所述针头110刺破所需注射的静脉血管并进入所述静脉血管。所述针筒111为圆柱形的形状。
所述输液软管113用于将所述药液容器3中的药液通过所述针头110注射到所述静脉血管中。
如图3所示，图3是本实用新型弹射功能的半自动注射装置较佳实施例的平面结构示意图。
所述移动装置10设置于所述滑轨30上，所述移动装置10在所述滑轨30上滑动。所述滑轨30中间为镂空带，当所述弹射功能的半自动注射装置1放置于人体部位上时，从所述镂空带可以接触到人体部位的皮肤表面。所述移动装置10还包括一条与所述滑轨30垂直的导轨14，所述角度调整装置13设置于所述导轨14上，所述角度调整装置13可以在导轨14上移动，从而移动所述针筒111的位置。
进一步地，如图4所示，图4是本实用新型弹射功能的半自动注射装置中移动装置较佳实施例的结构示意图。
所述弹射装置12与所述挡板112连接，当所述弹射装置12伸缩时，所述注射器11也伸缩（例如，向前移动或向后移动）。所述针筒111还架设于所述角度调整装置13上，该角度调整装置13可以上下伸缩，以调整针筒111与水平面（一般指人体部位的平面）的倾斜角度（例如，调整所述针筒111与水平面至15度）。进一步地，如图5所示，所述调整装置13上端还设置有圆形凹槽130，所述针筒111架设在所述圆形凹槽130内，所述针筒111可以在所述圆形凹槽130内移动。所述角度调整装置13还可以旋转（顺时针旋转或逆时针旋转），以带动所述圆形凹槽130旋转，从而调整针筒111的方向（即所述注射器11的针头110的注射方向）。
采用所述弹射功能的半自动注射装置1注射的方式如下：
当所述弹射功能的半自动注射装置1佩戴于人体部位（例如，手掌、手臂或手腕处）上时，所述捆绑装置20捆绑所述人体部位以使所述静脉血管凸起，患者选择（通过人眼分辨的方式选择）最粗的静脉作为注射静脉及注射位置，所述移动装置1在所述滑轨30上滑动，以靠近所述注射静脉，通过所述角度调整装置13（手动调整）以将所述针头110移动至所述注射位置并对准所述注射静脉（如图6所示），按下所述弹射装置12上的按钮，将所述注射器11弹射出去使得针头110插入所述注射静脉，完成注射。
以上仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效功能变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
