Description

安全疫苗注射针具 技术领域
本申请是有关一种注射器辅具，尤指一种使用于疫苗注射的安全疫苗注射针具。
背景技术
血液传染主要透过血液、伤口的感染方式，将病原传染至另一个个体，例如B型肝炎、C型肝炎及后天免疫缺乏症候群均可透过血液传染，而血液传染的发生常见于医疗使用的注射器材所导致，以及捐血与输血时的捐赠者与接受者检验不足或疾病的空窗期所造成。
根据卫生福利部统计，台湾护理人员每年每人发生近1.2-2.8次针扎，其中，污染性针扎(遭使用后之注射器具扎伤)则介于0.7-0.9次/年，而依照国内外研究报告指出透过针扎而导致的血液感染中，B型肝炎的感染率约为6-40％，C型肝炎为0-10％，后天免疫缺乏症候群则为0.3-0.5％，因此，为了维护医护人员的工作安全与健康，中华民国医疗法第56条规定自101年起，每年内按比例逐步完成全面提供安全针具。
因此，各医疗院所近年已逐渐推动使用安全针具的工作，但是，在安全针具的推广使用上，有一个部分是被忽略甚至遗忘的，此部分即是疫苗的注射，市面上的疫苗主要分为两种形式，一种是与一般注射药剂同样装设在药剂瓶中，需要注射时，直接以注射针具抽取后注射即可，这种疫苗注射时，医护人员可以直接使用市面上安全针具进行注射，因此，在安全上并无疑虑，而另外一种疫苗则是疫苗针结构，此种疫苗直接装在注射疫苗的针具内，注射时，仅需将疫苗针上套住注射针的安全套拔除，即可进行注射，然而，此种疫苗针并无任何安全防护结构，所以在疫苗注射时，还是经常会有针刺状况的发生，而且使用后的疫苗针也无法防止被二次利用，因此，在安全上仍有疑虑。
由上所述，相关疫苗针注射时，并不像注射其他药剂时，具有安全的注射针具可以使用，因此容易导致医护人员或患者在疫苗注射中或疫苗注射后 被刺伤或划伤的问题产生，因此，本案发明人积极进行改良创新，并经多年苦心孤诣潜心研究后，终于成功研发完成本件安全疫苗注射针具。
发明内容
为解决相关技术的问题，本申请的目的是在于提供一种疫苗注射的辅助针具。
为解决相关技术的问题，本申请的另一目的是在于提供一种避免医护注射疫苗时或注射疫苗后被疫苗针刺/划伤的安全疫苗注射针具。
为达成前述目的，本申请所提供的安全疫苗注射的辅助针具主要包括一操作件及一外套件，所述操作件包括一容置空间及至少一按压组件，所述容置空间为设于所述操作件内部，且所述操作件的两端均设有一开口与所述容置空间沟通，所述操作件其中一端的端面向所述操作件另一端的方向凹设有至少一沟槽，所述按压组件是设于所述沟槽内，所述按压组件一端与所述沟槽朝向所述沟槽开口的璧面连接，且所述操作件邻近按压组件的一端外缘表面环凹设有一卡固槽；
所述外套件包括至少一压迫部及至少一弹性定位部，所述外套件套设于操作件外缘，所述外套件邻近两端的位置分别设有至少一穿孔及至少一定位孔，所述压迫部设于所述穿孔内，所述弹性定位部设于所述定位孔内，所述压迫部朝向弹性定位部之一端与所述穿孔之一内侧璧面连接，所述弹性定位部朝向压迫部之一端与所述定位孔之一内侧璧面连接，且所述弹性定位部远离压迫部一端并朝向操作件的面上凸设有一定位凸块。
其中，所述卡固槽环凹于所述操作件及所述按压组件的外缘表面。
其中，所述操作件还包括至少一扣勾部，所述扣勾部设于所述操作件相对设有沟槽的另一端外缘壁面，且所述扣勾部远离所述按压组件的表面上设有一容置槽。
其中，所述定位凸块邻近所述压迫部方向的面为一斜面，而所述定位凸块远离所述压迫部方向的面为垂直于所述外套件内缘壁面的垂直面。
其中，所述定位槽邻近所述按压组件的面为一斜面，所述卡固槽邻近所述定位槽的面为与所述操作件外缘表面相互垂直的垂直面。

请参阅图1～4，本申请所提供之安全疫苗注射针具主要包括一操作件1及一外套件2，该操作件1为内部具有容置空间的圆筒结构，该操作件1的一端外侧环设有扣勾部11，该操作件1相对设有扣勾部11的另一端则由其端面向内凹设有二沟槽12，且该沟槽12朝向该沟槽12开口的壁面向沟槽12开口方向均延伸有一按压组件13，另外，该等按压组件13的两侧与该沟槽12两侧的壁面均分别具有一间隙14，而使该按压组件13形成一端连接于沟槽12壁面的弹性体，再者，该操作件1邻近该扣勾部11的外缘壁面环凹有一定位槽15，而该操作件1相对扣勾部11另一端的邻近其端面的外缘环设有一卡固槽16，其中该卡固槽16同时存在于该操作件1及该按压组件13的外缘表面上，且该卡固槽16朝向该扣勾部11的面为一垂直的抵顶面161，此外，该扣勾部11在远离该按压组件13的表面上设有一容置槽111。
该外套件2为中空的套筒，该外套件2邻近两端的位置分别设有二穿孔21及至少一定位孔22，该等穿孔21的位置是对应该操作件1的按压组件13的位置，且该等穿孔21中均设有一压迫部23，而该定位孔22中设有一弹性定位部24，该等压迫部23朝向该弹性定位部24的一端是与该等穿孔21的一内侧璧面连接，该弹性定位部24朝向该等压迫部23的一端是与该定位孔22的一内侧璧面连接，其中，该弹性定位部24远离该等压迫部23的一端朝向外套件2内部的表面设有卡固凸块241，该卡固凸块241朝向压迫部23的另一端表面是与该外套件2内部表面垂直的卡抵面2411，而该卡固凸块241相对卡抵面2411的另一端则为一斜面2412。
本申请所提供的安全疫苗注射针具组装时，是将外套件2套设于该操作件1外缘，并使外套件2上的二压迫部23迭合在该操作件1的二按压组件13之上，同时使外套件2的弹性定位部24上所设的卡固凸块241收纳到操作件1的定位槽15内。
请参阅图1～7，本申请所提供的安全疫苗注射针具使用时，是将疫苗针3由操作件1的后方穿入操作件1内部容置空间，并使疫苗针3后端供注射时，食指与中指扣勾的挡部31塞设在操作件1的扣勾部11所开设容置槽111中，然后，医护人员透过按压设于该外套件2相对外缘表面的二压迫部23，使二压迫部23向下抵在二按压组件13上，进而令二按压组件13由疫苗针3外缘相对的两侧压住疫苗针3，接着，在按压二压迫件23以固定疫苗针3的状况下，将疫苗针3前端的注射针32插入受注射者的注射部，此时，由于医护人员透过按压二压迫部23，以使二压迫部23下方的二按压组件13由疫苗针3外缘相对两侧固定住疫苗针3，可有效固定疫苗针3，避免疫苗针3注射时受力而带动操作件1向后推退，造成疫苗针3内缩的状况。
接着，医护人员透过按压疫苗针3的活塞杆33，便可将疫苗针3内的疫苗透过注射针32注入受注射者的体内，然后，医护人员再持续按压住二压迫部23，然后勾住操作件1的扣勾部11，并将操作件1向后拉，此时，由于该卡固凸块241朝向压迫部23方向的面为斜面2412，因此，当医护人员将操作件1相后拉时，操作件1的定位槽15前缘可以很顺利的滑过卡固凸块241的斜面2412，从而使得卡固凸块241脱离定位槽15，而让操作件1得以向后 拉动，同时，由于二压迫部23及二按压组件13均是背向操作件1与外套件2前端的一端与操作件1及外套件2连接，因此，当医护人员按压二压迫部23以利用二按压组件13固定疫苗针时，二压迫部23及二按压组件13均为朝向操作件1与外套件2前端的一端向下压住疫苗针3，而背向操作件1与外套件2前端的另一端则与操作件1及外套件2连接的状况，导致二压迫部23及二按压组件13均呈现前端受力下压的倾斜状态，因此，当医护人员将操作件1相后拉时，二压迫部23与二按压组件13会顺着倾斜的斜面滑移分离，令二压迫部23不再压住二按压组件13，而使得操作件1可以顺利向后拉。
而由于疫苗针3的挡部31是容置于操作件1的容置槽111内，因此，当操作件1被医护人员向后拉动时，疫苗针3亦随之被操作件1带动而向后移动，进而使得疫苗针3前端的注射针32脱离受注射者的注射部，并进入外套件2内，接着，医护人员持续将操作件1向后拉，即可令外套件2的弹性定位部24的卡固凸块241进入操作件1的卡固槽16内，此时，由于卡固凸块241相对斜面2412的另一面为垂直的卡抵面2411，而卡固槽16朝向定位槽15方向的面一为垂直的抵顶面161，因此，当卡固凸块241进入卡固槽16后，若要将外套件2向后拉或将操作件1向前推时，卡抵面2411会与抵顶面161相互抵住，以使得本申请所提供的安全疫苗注射针具无法再将外套件2向后拉或将操作件1向前推，令疫苗针3前端的注射针31被保持包覆在外套件2内的状况，以防止注射针31针尖外露而划伤或刺伤医护人员、受注射者或清理医疗废弃物的清洁人员。
另外，请配合参阅图8，本申请所提供的安全疫苗注射针具中，该卡固凸块241相对卡抵面2411的另一面与定位槽15朝向卡固槽16的一面中，其中之一设为斜面151、2411即可，本申请并不限制卡固凸块241相对卡抵面241的另一面必须为斜面2411，而是仅需当操作件1被向后拉时，卡固凸块241可以脱离定位槽15，而使操作件1可以顺利后拉的结构即可，或者，该卡固凸块241相对卡抵面2411的另一面与定位槽15朝向卡固槽16的一面两者均设为斜面151、2411亦可，再者，请参阅图2，本申请所提供的安全疫苗注射针具中，该操作件1的容置槽111入口周缘环设置有逆止挡块111，因此，当 疫苗针3由操作件1后方穿入操作件1的容置空间中，并使疫苗针3的挡部31置入容置槽111内后，透过逆止挡块111设置，即可令疫苗针3无法再由操作件1内取出，因此，可更有效防止疫苗针3的注射针31针尖外露而划伤或刺伤他人所造成的医疗事故发生，又，请参阅图9，本申请所提供的安全疫苗注射针具中，该操作件1在定位槽15与卡固槽16间的外缘表面可设置具有供卡固凸块241通过的凹面，使该操作件1被向后拉而卡固凸块241脱离定位槽15进入卡固槽16的间的移动过程更容易操作，避免卡固凸块241被外套件2内缘壁面下压而与操作件1外缘壁面产生过大的摩擦阻力。
由上所述，透过本申请所提供的安全疫苗注射针具，可以使得注射疫苗时，避免疫苗针的注射针造成的医疗针刺事故，同时，也可防止疫苗针的针具被拿来二度使用而造成医疗废弃物污染的状况，因此，本申请所提供的安全疫苗针具符合专利申请中新颖性、创造性及实用性的规定，依法提出专利申请。
此外，以上仅表达了本申请其中的部分实施例，但并非对本申请专利范围的限制，对于本领域技术人员来说，在不脱离本申请构思的前提下，还可以做出的若干变形和改进，均在本申请的保护范围之中。
