Description

安全防护输液针 技术领域
本发明涉及一种安全防护输液针， 尤其涉及一种具有防针剌的安全防护输 液针， 可用以避免医护人员被针头意外剌伤的风险。 背景技术
目前医护人员常利用静脉输液针对于病患施予注射药剂、抽血等等医疗行 为。然而， 在医疗程序时， 护理人员常常会因为针头插拔的疏忽而造成意外礼 伤的情况。
请参阅图 1， 为现有输液针的正面结构立体图。 如图所示， 输液针 100包 括有一保护针盖 10、 一针头 11、 一本体 13及一输液管 12。
输液针 100未使用之前， 保护针盖 10会套盖于针头 11上。 输液管 12作 为药剂注入或血液流出的通道， 其一端通过本体 13衔接针头 11， 而另一端设 置有一接头部 121， 接头部 121用以配接一可承装药剂或血液的管体、 导管或 容器。 此外， 本体 13的侧边尚设置有一针翼部 131。
当输液针 100进行使用时， 医护人员可将保护针盖 10取下， 以令针头 11 裸露在外。 接着， 医护人员藉有针翼部 131的抓取而让针头 11插入病患的静 脉之中， 以进行药剂的注射或血液的抽取。
当输液针 100 使用完毕时， 医护人员会从病患身上抽出已使用过的针头
11， 并重新地将保护针盖 10套回针头 11之上。 由于该保护针盖 10的套孔极 小，第一时间不易精准套入， 很有可能因为操作上的不愼而致使医护人员遭针 头 11意外剌伤， 进而造成病毒感染 (如爱滋病、 肝炎、 SARS等等:)的可能性。 如此， 对于医护人员的生命安全而言， 十分危险。
在此， 本发明将提出一种具有防针剌的安全防护输液针， 可增加针头回收 时的安全性， 防止医护人员遭针头意外礼伤而受到病毒感染，将会是本发明欲 达到的目的。 发明公开
本发明的一目的， 在于提供一种安全防护输液针， 利用一安全罩的设置， 当医护人员欲回收已使用过后的针头时，只要将输翼针的针翼部往后拉至安全 罩的后端处， 针头即可回收在安全罩之内， 以避免医护人员遭使用后的针头意 外礼伤的风险。
本发明的一目的， 在于提供一种安全防护输液针， 其安全罩的前端侧边设 有一斜面开口及后端侧边设有一凹型开口， 当输液针使用时， 针翼部将设置在 斜面开口中， 利用斜面式的设计， 以令针头进入人体静脉时有一定的角度。
本发明的一目的， 在于提供一种安全防护输液针， 当输液针使用后， 针翼 部将从斜面开口往后拉至凹型开口中， 针翼部可以确实锁在凹型开口之中， 而 达到针头安全回收的目的。
为了达到上述的目的， 本发明提供一种安全防护输液针， 包括： 一本体， 其侧边设置有一针翼部， 其中一端连接一针头， 另一端连接一输 液管； 及
一安全罩， 为一用以容置本体的中空罩体， 其前端侧边设有一斜面开口， 后端侧边设有一凹型开口，斜面开口与凹型开口之间存在一缝隙， 当针翼部设 置于斜面开口时， 针头突出于安全罩之外， 当针翼部从斜面开口通过缝隙往后 拉至凹型开口时， 针头被包覆于安全罩之内。
上述的安全防护输液针， 其中该针翼部包括一垂直边， 该针翼部于该凹型 开口位置时， 该凹型开口的垂直壁将抵挡该针翼部的垂直边。
上述的安全防护输液针， 其中该安全罩的后端罩体上设有一防滑部。 上述的安全防护输液针，其中该斜面开口包括用以导引该针翼部进入该缝 隙之中的一导角。
上述的安全防护输液针， 其中该针翼部的厚度大于该缝隙的间距。
以下结合附图和具体实施例对本发明进行详细描述， 但不作为对本发明的 限定。 附图简要说明

下面结合附图对发明的结构原理和工作原理作具体的描述：
请参阅图 2， 为本发明输液针本体的立体图。 如图所示， 本发明输液针本 体 23的侧边固设一针翼部 231， 其中一端连接一针头 21、 另一端连接一输液 管 22。该输液管 22将作为药剂注入或血液流出的通道，其中一端连接本体 23， 而另一端设置有一接头部 221， 接头部 221用以配接一可承装药剂、 生理食盐 液或血液的管体、 导管或容器。
请参阅图 3A-图 3D分别为本发明安全罩的俯视图、 正视图、 右视图及左 视图。 如图所示， 安全罩 25为一中空罩体， 其前端侧边设有一斜面开口 261， 后端侧边设有一凹型开口 263， 而斜面开口 261与凹型开口 263之间存在一缝 隙 262。
请参阅图 4A-图 4B分别为本发明安全防护输液针结构未包覆针头前的立 体图及正视图。 本发明输液针 200的组合结构中， 本体 23将组放在安全罩 25 内部。 在输液针 200未使用之前， 本体 23 的针翼部 231将摆置于安全罩 25 的斜面开口 261位置， 此时针头 21将突出于安全罩 25之外， 并且针头 21的 上套设有一保护针盖 20。
当输液针 200进行使用时， 医护人员也可将套在针头 21上的保护针盖 20 取下， 以令针头 21裸露在外。 之后， 通过针翼部 231的抓持， 医护人员可将 针头 21插入病患的静脉、血管或身体之中， 以进行药剂的注射或血液的抽取。 再者， 当针翼部 231摆置于斜面开口 261时， 利用斜面式的设计， 安全罩 25 的罩体结构不仅可以压抵本体 23及其针翼部 231产生倾斜，使得针头 21进入 人体静脉时具有一定的角度， 以避免穿破静脉而致血肿， 并且安全罩 25的罩 体结构可以紧密地贴合在本体 23及其针翼部 231之上，避免注射时产生滑动。
接着， 请参阅图 5A-图 5B分别为本发明安全防护输液针结构包覆针头后 的立体图及正视图。 输液针 200使用完毕后， 医护人员可将已使用的针头 21 抽离于病患身上。 之后， 当医护人员欲将已使用过后的针头 21进行回收处理 时， 可抓持针翼部 231往后移动， 则针翼部 231将从斜面开口 261通过缝隙 262拉至凹型开口 263的位置，此时针头 21将完全地被包覆于安全罩 25之中。 如上方式据以操作，使用过后的针头 21将可以顺利地被回收在安全罩 25之中， 再进行废弃处理。
本发明一实施例中， 斜面开口 261设置有一导角 2610， 当针翼部 231从 斜面开口 261往后拉引时， 导角 2610可用以导引针翼部 231顺利地进入于缝 隙 262中。 并且， 本发明一较佳实施例中， 针翼部 231 的厚度将会大于缝隙 262之间距， 则针翼部 231通过缝隙 262时，将会撑开缝隙 262而使安全罩 25 的部分罩体产生形变。 之后， 针翼部 231通过缝隙 262进入凹型开口 263时， 原本形变的安全罩 25罩体将恢复原有的形态， 则凹型开口 263的垂直壁 2631 将抵挡针翼部 231的垂直边 2311(如图 2、 图 3B及图 5C所示)， 阻隔针翼部 231再次进入缝隙 262的机会， 让针翼部 231确实锁在凹型开口 263中， 而达 到针头 21安全回收的目的。
又， 本发明一实施例中， 安全罩 25的后端罩体上设有一防滑部 251。 利 用防滑部 251的防滑作用， 当医护人员欲处理已使用过的针头 21时， 一手先 紧握安全罩 25的防滑部 251， 另一手再抓持针翼部 231往后拉动， 则针翼部 231将可稳固地拉至凹型开口 263之内， 以避免手指打滑于安全罩 25之上而 被针头 21意外剌伤的危险。
当然， 本发明还可有其它多种实施例， 在不背离本发明精神及其实质的情 况下， 熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但 这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。 工业应用性
本发明提供的安全防护输液针， 利用一安全罩的设置， 当医护人员欲回收 已使用过后的针头时， 只要将输翼针的针翼部往后拉至安全罩的后端处， 针头 即可回收在安全罩之内， 可以避免医护人员遭使用后的针头意外礼伤的风险。
