所述自动定位及弹射功能的注射装置1放置于人体部位（例如，手臂或手腕等人体部位）上以通过所述血管扫描仪22自动寻找人体组织中的静脉血管，并自动将注射器11的针头插入到所述静脉血管中，之后将所述药液容器3中的药液注射到所述静脉血管中。
在本实施例中，当所述自动定位及弹射功能的注射装置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30捆绑所述人体部位，以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，能够更明显地分辨出静脉血管。所述捆绑装置30为一封闭式圆圈，该捆绑装置30的可以佩戴于手臂或手腕上，并通过调节所述封闭式圆圈的半径来控制所述捆绑装置30的松紧度。在本实施例中，所述捆绑装置30可以是，但不限于，封闭式橡皮筋、封闭式绷带、封闭式充气圈等。所述控制器2控制所述捆绑装置30，以控制所述捆绑装置30的松紧度。当所述针头110进入所述静脉血管后，所述控制器2控制所述捆绑装置30，以停止对所述人体部位进行捆绑（即增大所述圆圈的半径）。
此外，如图1所示，当所述自动定位及弹射功能的注射装置1佩戴于人体部位（手腕）上时，所述自动定位及弹射功能的注射装置1自动完成注射。
所述控制器2控制所述血管扫描仪22以获得所述静脉血管的坐标信息。具体地说，所述血管扫描仪22在所述滑轨60中移动，扫描所述镂空带中所述静脉血管。如图7所示，经过所述血管扫描仪22扫描后，所述人体部位4中包括三条静脉血管400，其中一条静脉血管400与另一条静脉血管400有交叉点401（图中有两个交叉点401）。
所述控制器2根据所述静脉血管400的坐标信息确定注射血管及该注射血管的注射位置。具体地说，所述控制器2根据所述静脉血管400的三维坐标信息计算每条静脉血管400的粗细程度，其中，最粗的静脉血管400作为注射血管，根据所述静脉血管400的坐标信息计算出静脉血管400的交叉点，在所述注射血管中任意选取一段血管，该选取的一段血管的距离大于或等于所述针头110的长度，且该选取的一段血管中没有交叉点，将该选取的一段血管的起始端作为注射位置。
所述控制器2控制所述角度调整装置13以根据所述注射血管的走向调整所述针头110的注射方向。具体地说，所述注射方向为所述针头110在水平面的方向，如图8所示，该水平面的方向与所述注射血管的走向一致。
所述控制器2从所述移动装置10获得该针头110的初始三维坐标。
所述控制器2控制所述移动装置10将所述针头110从所述初始三维坐标移动至该注射血管的注射位置。
所述控制器2控制所述弹射装置12弹射所述注射器11以将所述注射器11的针头110插入至所述注射血管。具体地说，所述控制器2控制所述弹射装置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。
所述控制器2控制所述驱动装置20中的伤口保护装置24贴合到所述注射血管的注射位置以保护伤口。
此外，所述控制器2控制所述捆绑装置30以使人体部位的静脉血管在皮肤表面凸起。需要说明的是，由于婴儿（两岁以下）的人群中，血管小且隐藏的深，即便采用所述捆绑装置30，也可能无法使得皮肤表面凸起静脉血管，因此，采用捆绑装置30的本实用新型更适用于成年人（18岁以上的群体）。
此外，所述输入装置40用于输入相关参数，以利于所述控制器2控制所述移动装置10、所述弹射装置12、角度调整装置13、血管扫描仪22及伤口保护装置24。具体地说，用户在所述输入装置40中输入用于控制所述角度调整装置13的注射角度（所述注射角度为针头与人体部位表面的倾斜角度，例如，15度到30度范围内选定的一个注射角度）。
所述显示装置50用于显示所述血管扫描仪22扫描所获得的静脉血管400的三维坐标信息及图像。在其它实施例中，所述显示装置50可以远离所述自动定位及弹射功能的注射装置1。具体地说，通过一条图像数据线（例如，HDMI线、VGA线等任意合适的图像数据线）与所述自动定位及弹射功能的注射装置1中的控制器2连接，此时，所述显示装置50可以与所述自动定位及弹射功能的注射装置1分离。
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。
