本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种内置多节式采血针的血糖仪采血笔，在采血笔内的采血针容置部101中依次设置多个采血针，每次采血时可通过最靠近采血笔笔尖处的采血针进行采血，无需用一次手动替换一次，方便用户使用。
参照图1，图1为本发明内置多节式采血针的血糖仪采血笔第一实施例的结构示意图。
在本发明一实施例中，内置多节式采血针的血糖仪采血笔内设置一采血针容置部101，用于容置采血针11，本实施例中，可设置多个采血针11，多个采血针11沿采血笔10的方向依次排列在采血针容置部101中，在使用内置多节式采血针的血糖仪采血笔进行采血时，通过按压或其他驱动的方式驱动最靠近采血笔笔尖处的采血针11弹出采血笔的笔尖外侧进行采血，采血后随着驱动力减小，采血针11便回弹至采血针容置部101内。
本发明实施例在内置多节式采血针的血糖仪采血笔中依次排列多个采血针11，在通过采血针11采血时可驱动最靠近采血笔笔尖处的采血针11弹出采血笔的笔尖外侧进行采血，采用多个采血针11，无需用一次手动替换一次，方便了用户使用，并且解决了残障用户使用存在困难的问题。
参照图2和图3，图2为本发明内置多节式采血针的血糖仪采血笔的采血针一视角的结构示意图；图3为本发明内置多节式采血针的血糖仪采血笔的采血针另一视角的结构示意图。
在上述实施例中，采血针11包括针套和穿设在针套中的针头112，其中，针套包括卡合部1111和位于卡合部1111下方的支撑部1112，针头112穿设在支撑部1112中部；同时，在采血针容置部101内沿采血针11方向凸设第一卡合突起1011，采血针11的卡合部1111卡合在第一卡合突起1011两侧，从而固定采血针11。
进一步地，采血针11的卡合部1111包括相对设置的两连接壁11111，连接壁11111的下方沿连接壁11111的宽度方向延伸有卡合壁11112，卡合壁11112的一端与支撑部1112连接。本实施例中，两连接壁11111可设置为平行，并且连接壁11111与支撑部1112垂直设置，位于两连接壁11111下方的卡合壁11112卡合在第一卡合突起1011的两侧；两连接壁11111还可以设置为呈一定角度，例如两连接壁11111的自由端分别向相背离的方向，与支撑部1112呈角度设置，位于两连接壁11111下方的卡合壁11112卡合在第一卡合突起1011的两侧，两连接壁11111之间的角度可根据采血针容置部101的大小，以及第一卡合突起1011的宽度进行设置，以保证通过两连接壁11111的卡合作用将采血针11与第一卡合突起1011固定。
进一步地，卡合壁11112的自由端远离连接壁11111的一面设置为斜面，卡合壁11112与支撑部1112连接的一端的长度小于卡合壁11112相对于该端的另一端的长度，卡合壁11112长度较长的一端卡合在第一卡合突起1011的两侧，以固定血针11。
参照图2和图3，在上述实施例中，采血针11还包括固定部113，该固定部113设置在支撑部1112下方并与支撑部1112连接，用于固定针头112；同时，针头112包括设置在针头112中部的固定端1121，在安装时，针头112穿过支撑部1112和固定部113，针头112的固定端1121卡合在固定部113下方，从而将针头112固定。
参照图1，在上述实施例中，内置多节式采血针的血糖仪采血笔还包括抽拉部，该抽拉部包括抽拉块1021、抽拉杆1022、卡合块1023和第一弹性件1024，其中：抽拉块1021设置在采血笔外侧，抽拉杆1022设置在采血笔内并与抽拉块1021连接，卡合块1023连接在抽拉杆1022上，第一弹性件1024连接在抽拉杆1022与采血笔的上盖之间，本实施例中该第一弹性件1024优选采用弹簧。
进一步地，内置多节式采血针的血糖仪采血笔还包括设置在采血笔外侧的释放按钮103。在需要使用采血笔进行采血时，通过抽拉块1021带动抽拉杆1022沿采血笔向上移动，进而压缩第一弹性件1024，抽拉杆1022的移动同时带动卡合块1023移动至与释放按钮103卡合；按下释放按钮103后，卡合块1023与释放按钮103脱离，第一弹性件1024恢复形变，通过形变的压力带动抽拉杆1022沿采血笔向下移动，当抽拉杆1022与位于采血笔的笔尖处的采血针11接触时，具体地，抽拉杆1022的末端会接触到采血针11的支撑部1112的上端面，通过压力将采血针11顶出至采血笔的笔尖外侧，从而完成采血。
参照图1，进一步地，内置多节式采血针的血糖仪采血笔还包括一用于容置废旧采血针的废旧容置腔104，即用过的采血针11最终会容置在该废旧容置腔104中，而无需手动将其取下；同时，在废旧容置腔104内，沿采血针方向凸设有第二卡合突起1041，用过的采血针11的卡合部1111卡合在第二卡合突起1041两侧，从而固定废旧采血针。
参照图1，在上述实施例中，内置多节式采血针的血糖仪采血笔还包括推出部；推出部包括推出件1051和顶出件1052，其中，推出件1051用于推出用过的采血针11，顶出件1052与推出件1051连接，用于将用过的采血针11顶出至废旧容置腔104，顶出件1052的一端与采血笔的笔尖处的内壁之间连接有第二弹性件1053，本实施例中该第二弹性件1053优选采用弹簧。
进一步地，抽拉杆1022的末端向采血针11方向设置为弯曲部10221，该弯曲部10221上向采血针11的方向设置一突起10222；当抽拉块1021带动抽拉杆1022沿采血笔向上移动时，突起10222与推出件1051的一端卡合，带动推出件1051向上移动，在推出件1051向上移动的同时，推出件1051的另一端向采血针11移动并接触到采血针11的支撑部1112，使采血针11翻转从而推出采血针11，随着推出件1051带动顶出件1052继续向上移动，顶出件1052连接有第二弹性件1053的一端的端面与采血针11的支撑部1112底部接触，在顶出件1052向上移动的过程中，将采血针11顶出至废旧容置腔104中。
参照图1，在上述实施例中，采血针容置部101的顶部与采血笔的上盖之间连接有第三弹性件106，在采血针容置部101中装有采血针11时，第三弹性件106处于压缩状态，当靠近采血笔笔尖处的采血针11被顶出后，通过第三弹性件106的弹性力推动下一个采血针11至相应的位置。
在上述实施例中，内置多节式采血针的血糖仪采血笔还包括设置在采血笔的笔尖处的第四弹性件107，在按下释放按钮103后，抽拉杆1022推动采血针11至第四弹性件107时，采血针11的针套底端挤压第四弹性件107并被推出至采血笔的笔尖外侧进行采血，在采血后由于第四弹性件107的恢复力，采血针11会收缩回至采血笔中。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
