Abstract

一种含有外装式注射针而内缩呈自动偏斜的安全针筒，本发明包括：一针筒装置，一中空针具安装于该针筒装置上，以及一活塞装置滑合于针筒装置中，其中空针具可拆装地旋合于针茎部上，针茎部插置于针筒装置的针套部，活塞前端凹设一偏斜承窝，以吻合针头部。当注射完毕后，由活塞带动针头部后缩退入针筒内，并使该中空针偏斜不致再向外突出，以防止刺伤他人或感染病毒；而该中空针可自针筒的外面彷合于该针茎部，故而安装方便，且可换装不同尺寸的注射针于针筒上。

Description

含有外装式注射针而内缩呈自动偏斜的安全针筒
本发明涉及一种医用注射器，具体地讲是一种含有外装式注射针而内缩呈自动偏斜的安全针筒。
习用的注射针筒，于注射完毕后，若针尖沾到患有传染性或危险性症状(如AIDS)病患的血液时，医务人员、护士、清洁人员都有被感染的危险；即使设有传染病毒时，注射针的刺尖亦有刺伤他人的危险。
为此现发明一种安全注射器，如美国52324458号专利；一种内缩式自动偏斜安全注射器针筒，结构特征是在该注射器的前端设有一中空的针筒，在中空针筒的后部设有一针头部，一活塞滑入于中空针筒内，活塞的前端设有一凹入的偏斜窝吻合于呈圆弧面的针头部，当活塞将药液注入人体后，活塞再依一推力使针头部滑扣入活塞前端的偏斜窝内偶合在一起，并随着活塞的后退而内缩至针筒内偏斜，而不致再伸出，克服了上述之缺陷；但此种安全注射器在装设针头时，需从针筒活塞的滑入端伸入其针筒内，而这种操作对于细长的针筒来讲非常不方便。
本发明人有鉴于此，乃加以研究创新，提出本发明，其目的在于提供一种含有外装式注射针内缩呈自动偏斜的安全针筒，使之不仅可有效地避免传染有危险，而且可使注射针安装更方便快捷，且可换装不同规格的注射针于针筒上。
本发明的目的是这样实现的：一种含外装式注射针而内缩呈自动偏斜的安全针筒，包括有一针筒装置，其内设有一针筒部供装容液药，有一针筒轴心位于针筒部的中心，及一针套部自该针筒部向前渐缩以供插置一中空针具，与一肩部介于针筒部与针套之间；该中空针具含有一带有针尖的中空针，设于针茎部上，该针茎部插置于针筒装置的针套部内，一针头部设于该针茎部的后端，与一针轴心位于该中空针具的中心，当安装中空针具于针筒装置上时，该针轴心与针筒轴心对正或平行；一活塞装置包括：一活塞往复滑合于针筒内，一偏斜承窝呈弧形且自该活塞前面向后凹入窝心界定一纵向轴与针筒轴心形成一锐角，一引导口自活塞前面向后渐缩以与该偏斜承窝相通，且设地面对该针头部滑扣入该偏斜承窝中而被自动偏斜，一活塞杆由一偶合件连接于该活塞，活塞的后方凹设一凹槽与该偶合件吻合，以扣接该活塞于活塞杆前端，与一把手连接于活塞杆的后端以为握持、注射用，以及一活塞轴心位于活塞与活塞杆的中心且与该针轴心对准以正常安装针具；其特征在于所述的针套部包括一针套孔贯穿于该针套部，一环状槽凹设于针套孔的内壁，一截头圆窝自针筒肩部向前所设的圆柱窝再往前渐尖凹陷形成渐层孔以与该针套孔相通；中空针有一偶合销设于该中空针的后端，偶合销内设有一杆窝向前凹设并与穿透中空针的针孔相通，而杆窝内壁上螺旋地凹设一阴螺纹槽；该针茎部有一中空截头圆锥部吻合该针套部的截头圆锥窝，一迫紧环嵌入该截头圆锥部前方的内环槽与针套部的环槽中，一中空杆部自该截圆头锥部向前突伸，于中空杆部上至少横生一凸耳以旋合该中空针偶合销中的阴螺纹槽，使该中空针可在针筒的外面直接拆卸地旋装于该针茎部；一扩大的圆筒部设于针茎部的后端，以吻合于该针套部的圆柱承窝；而该针头部藉由一中空部连接至该针茎部，于针头后端的圆弧面有一中央射孔与位于颈部及该扩大圆筒部上的一排气槽及颈部通孔相通，而与偶合该中空针于针茎部时还与针孔相通。
本发明系利用中空针头上的偶合销内与中空部凸耳的旋合，使注射针能在针筒的外成方便的拆装，使之不仅可有效地避免传染有危险，而且可使注射针安装方便，且可换装不同规格的注射针于针筒，从而实现本发明的目的。

下面将结合实施例及其附图详细说明发明：
请参见图1-图6，本发明包括：一针筒装置1，一中空针具2安装于该针筒装置1上，以及一活塞装置3滑合于针筒装置1中。
针筒装置1包括：一针筒部11，含有一筒内部10以装容药液4与针筒轴心100位于针筒部11的中心；一针套部12，该针套部至针筒部11向前渐缩，一肩部13a介于针筒部11与针套部12之间，以及一针筒后凸缘14。
针套部12包括：一针套孔121贯穿针套部12，一环槽122设于针套孔121的内壁，一截头圆锥窝123自针筒肩部13a向前所凹设的圆柱窝124，再向前渐尖凹设形成渐层的渐缩孔并与针套孔121相贯通。
中空针具2包括：一中空针21其上带有一针尖211，一偶合销212设于该中空针21的后端，一杆窝213向前凹设以与穿通中空针21的针孔210相通，而杆窝213壁上螺旋凹设有阴螺纹槽214；一针茎部22有一截圆锥部22a，吻合于该针套部12的截头圆锥窝123，一迫紧环221嵌入该截头圆锥部22a前方的内环槽221a与该针套部12的环槽122中；一中空杆部222自截头圆锥部22a向前伸，于中空杆部222上至少横生一阳凸耳223以旋合该中空针21的偶合销212中的阴螺纹槽214，使该中空针21可在针筒装置1外面直接可拆卸地旋装于该针茎部22上；一扩大圆筒部224设于针茎部22的后端以吻合该针套12的圆柱窝124；一针头部23，藉一中空颈部24a连接至该针茎部22，针头部23后端呈圆弧面并设有一中央射孔231与位于颈部24a及该扩大圆筒部224上的一排气槽24及颈部通孔220相通，而于偶合该中空针21于针茎部22时还与该针孔210相通，与一针轴心200位于中空针具2的中心，当安装中空针具2于针筒装置1上时，该针轴心200与针筒轴心100对正以供注射使用。当用于静脉注射时，针轴心200与针筒轴心平行而非对正。
活塞装置3包括：一活塞31往复滑合于针筒部11中，一偏斜承窝32呈弧形且至活塞的前面310向后凹入其窝心界定一纵轴321与针筒轴心100形成一锐角A；一引导口33自活塞前面310向后渐缩以与上述的偏承窝32相通且设影地面对该针头部23，使缩退的中空针具2进入针筒部11内后，针头部23滑扣入偏承窝32中而被自动偏斜(如图5所示)。一活塞杆35藉一偶合件36连接于活塞31，活塞31后方凹设一凹槽34以与该偶合件36吻合并由此扣接该活塞31于活塞杆35的前端；一把手37连接于活塞杆35后端用于握持、注射用；一活塞轴心300位于活塞31与活塞杆35的中心且与该针轴心200及针筒轴心100对准以正常安装针具2，以供注射之用。
当使用本发明注射时，将活塞31前推使药液4经由图3所示的中空针21射入人体中。药液4注射完毕后，施压D于活塞杆35上，使针头部23滑扣入偏斜承窝32中，使针具2与活塞31偶合，如图4所示。
后退活塞31及所偶合的针具2，针具2乃被自动偏斜，如图5所示，此时若再向前推F活塞杆35，因针尖211已被抵紧于肩部13A、遂被折弯而无法向外穿经针套筒121向外伸针尖，故可避免刺伤使用者、医护人员及清洁工者。
本发明与习知针筒相比效果是显著的：
1．打完针后，缩退活塞，可一并将偶合的针具退入针筒内部之中，而不致于外促，即使偶有意外伸出的趋势时，亦必被渐层的渐缩孔12a的诸角落所阻，如图5所示的肩部13a、圆柱窝124、环122等处，而使再度向外伸出刺入的可能性几乎为零，从而确保医疗安全卫生。
2．除能自动偏斜用毕的针具外，尚可自针筒外旋合置换不同大小的针具，外装中空针21时仅需旋转偶合销212，以吻合该针茎部22上的凸耳223，即可能轻便地外装中空针具21于针茎22上。
3．在注射过程中，由于有截圆锥体22a的设计，针具2不会被活塞31推顶药液4的压力所向前推出，跑出针外，妨碍正常的注射操作。
4．与习知的针筒比较，并无增加多少零件，构造极为简单，于不会影响制作成的原则下，能牢靠地自动偏斜注射完毕后的针具，而能促进医疗安全。
本发明的针茎部22上可加设至少一个突缘或突条，以卡合设于针套部12中孔内的一突缘或突条，由此于旋合该中空针21于针茎部22上以安装针具2于针筒装置1上时，因针茎部22会被卡挡于针套部12内的突缘上而不再自由转动，促使该中空针21稳当地旋合于该针茎部22上，使针具2妥适地安装于针筒装置1上。
