Description
优先权请求
本申请请求享有2010年7月15日提交的美国临时专利申请序列第61 / 399,629号的优先权,该申请通过引用将其整体并入到本文中。
技术领域
本发明大体上涉及医疗装置的领域,并且更具体地涉及防止意外针刺的用于血液收集或血液输注的安全产品的领域。
背景技术
收集来自于患者的血液或输注到患者中是世界上最常执行的两个医疗程序。血液收集是必需的,以便评估身体机能的化学组成,以便诊断医学状况,且确认治疗计划,且输注也是必需的,以输送液态的药品、林格氏溶液(ringer)或其它制备物。除了前述内容,由针或其它尖锐的医疗装置引起的伤害和潜在的绝症传染的相关风险仍是对全球卫生保健工作者的健康和安全的主要威胁。此外,由尖锐物伤害引起的疼痛、疾病和缺勤对医疗职业中的已经很有限的人力资源构成了较大的影响。
大多数尖锐物伤害是护士受到的,且出现在病房和手术室中,但医生、牙科医生和其他医务人员也是受害者。辅助人员如清洁工和洗衣人员和其他下游工作者也有风险。
用语"针刺"伤害归已经成为了用于描述由以前使用的污染的导管、针或其它经皮穿刺装置意外穿透皮肤的用语。养成较安全的工作习惯和使用结合针刺防护技术的医疗装置的组合可防止这些潜在很严重的伤害中的许多伤害。
美国国会采取了行动来应对受来自于尖锐物伤害的影响血液带有的病原体感染的不断增长的忧虑,以及应对加强雇员保护的最近的技术发展。在2000年11月6日,"Needle Stick Safety and Prevention Act"写进了法律,其要求美国的所有卫生保健设施为他们的员工评估、购买和提供结合针防护的医疗装置。美国的卫生保健雇主现在还被要求保持尖锐物伤害记录,且涉及在结合针防护的工作实习控制和装置的评估和实施中的非可管理的潜在暴露的卫生保健工作者。
因此,尖锐的医疗器械(如,解剖刀片和注射器针)的安全处理已经变成了美国政府以最高水平解决的重要问题,因为在处理尖锐医疗器械(通常称为"医疗尖锐物")期间通过意外皮肤刺穿接触可能传染疾病。
存在描述意外针刺伤害的若干场景:首先,处理者在针已经使用后试图将针再盖住时可能会受到注射器针刺。第二,处理者在将其转移至适合的"尖锐物容器"时可受到注射器针刺。 第三,处理者或其他人在接触已经丢弃未受保护和未被注意的注射器和针时可能被刺。第四,转移医疗废物的人可受到未受保护、未盖住或不当地保存的注射器和针刺。
总体上,由于处理者在再盖住时可被针刺的极端可能性,故认为再盖住注射器针是"不安全的",且本发明提出了一种改进的安全系统,以用于防止与血液收集套件相关的尖锐物伤害。
发明内容
因此,本发明的目的在于提供一种改进的I.V.输注或血液收集设备。
本发明的另一个目的在于提供一种具有增强的安全特征的改进的I.V.输注或血液收集设备。
本发明的又一个目的在于提供一种容易使用且廉价地制造的改进的I.V.输注或血液收集设备。
当结合附图查阅时,这些及其它目的将变得清楚。

具体实施方式
I.V.输注或血液收集设备包括I.V.输注套件和适于包绕I.V.输注套件或血液收集设备的安全护罩。I.V.输注或血液收集设备包括翼本体,翼本体具有中心部分,中心部分具有针连接到其上的近端和管路连接到其上的远端。还提供了开孔,开孔延伸穿过翼本体,以允许流体在针与医疗管路之间流动。翼本体包括从中心部分的相对侧水平地向外延伸的一对大致共面的翼,以及从中心部分大致垂直于翼向上延伸的抓握部。
安全护罩适于包绕翼本体,且包括适于覆盖患者皮肤的下护罩区段和上护罩区段。相应的下护罩区段和上护罩区段铰接地连接在第一端处,且适于在相应的相对端处连接到彼此上,以形成腔室。腔室适于将输注套件收纳于其中。安全护罩包括前端,IV套件的针延伸穿过前端来使用,以及后端,IV输注套件管路延伸穿过后端。所述安全护罩的侧壁包括一对相对的槽口,IV输注套件的相应的翼适于通过槽口滑动地收纳。
长形槽口定位在安全护罩的顶壁中,抓握部延伸穿过顶壁。长形槽口包括邻近安全护罩的后端的锁定构件,用于在针缩回到腔室中时将针保持在永久锁定位置。因此,当成对的相对槽口和长形槽口的长度足以使IV输注套件能够从操作位置移动至安全位置,在操作位置,针露出以备使用,在安全位置,针完全地缩回到腔室中且抓握部锁定地收纳在锁定构件中。
优选实施例的详细描述
尽管下文将更为完整地描述本发明,但首先应当理解的是,本领域的技术人员可改变本文所述的本发明,同时仍实现本发明的有利效果。因此,以下的该描述将被理解为针对适合领域的技术人员的宽泛的教导公开内容,且不应当理解为限制本发明。
为了方便阅读,在以下的该描述中,I.V.输注或血液收集设备有时将被称为"BCS"—血液收集套件。
如图中所示,根据本发明的BCS50包括I.V.输注套件100和安全护罩200。
I.V.输注套件100包括翼本体105,翼本体105具有中心部分110,中心部分110具有针120连接到其上的近端115和管路130连接到其上的远端125。纵向开孔135延伸穿过翼本体105的中心部分110,以允许流体在医疗管路130与针120之间流动。翼本体105还包括从中心部分110的相对侧水平地向外延伸的一对大致共面的翼140。抓握部145从中心部分110大致垂直于翼140向上延伸。根据行业中的惯例,翼本体105和翼140被称为"蝴蝶状件"。将注意到的是,大体上翼140、中心部分110、开孔135和抓握部145模制为单个单元。相应的翼140连接到翼本体105上的区域比翼更薄,使得翼140可相对于翼本体105弯曲。用于翼本体105的制造技术和材料是本领域的技术人员公知的。 此外,针120和医疗管路130通过适合的构件连接到翼本体105上,适合的构件也是本领域的技术人员公知的,如胶、氰基丙烯酸盐粘合剂或者热粘合剂或者其它类型的粘合剂。
如本文中上文简要提到的那样,抓握部145与翼本体105一体地模制,且从其上向上在其宽度的大约80%与其长度的33%之间延伸。抓握部145的顶部从近端115至远端120向上成角,且包括一系列沿轴向延伸的凸脊150,凸脊150有助于将如本文在下文中更为详细阐述的那样处理BCS。
大体上在200处指出的安全护罩适于覆盖患者的皮肤,且包括适于连接在一起来形成腔室227的具有第一铰链端215的上护罩区段210和具有第二铰链端225的下护罩区段220。在所示的实施例中,相应的第一端215和第二端225终止于活铰链222,且相应的相对的上护罩端230和相对的下护罩端240适于如图16中最佳示出那样咬合在一起。咬合闭合构件244是在咬合配合连接的标准悬臂梁类型。本领域的技术人员将注意到的是,其它类型的闭合机构也可使用,如对于本领域技术人员而言公知的支柱和支座、胶合在一起的方法的或其它类型的闭合构件。
当相应的护罩区段210,220连接来形成腔室225时,安全护罩的侧部为仿形的,以在其相对侧中形成长形槽口或凹口250。此外,长形纵向槽口255位于上护罩区段210中,且终止于用作将I.V.输注套件在使用之后锁定在锁定位置的加宽带260中。在本发明的另一个实施例中,槽口255的终止端还包括一对柔性"指部"242,其从槽口235的相对侧延伸,且指向安全护罩200的医疗管路端,且共同地形成用于在使用之后将I.V.输注套件保持在锁定位置的锁定构件。将要注意的是,I.V.护罩的后端应当足够长,以使针120能够通过单手缩回到"安全"位置或锁定位置。更具体而言,从安全护罩200的管路端到锁定构件的终止端的距离应当足够长,以允许利用使用者的拇指和中指来抓握安全护罩,同时食指接合抓握部145的针端,且使针120滑动到安全护罩200中,直到锁定构件完全地接合抓握部,因此针将完全地缩回,且永久地锁定在安全护罩内以用于安全处理。
长形槽口250和255构造和布置成用以使IV输注套件的翼140能够从操作位置移动至安全位置,在操作位置,针120露出以备使用,在安全位置,针120完全地缩回到腔室225中。在完全缩回时,翼140定位成邻近安全护罩的管路端,且抓握部145锁定地收纳在安全护罩的顶壁中的长形槽口的锁定构件部分中。
尽管已经描述了某些示范性实施例,但显然的是,许多备选方案、改型、置换和变型将按照前述描述而对于本领域的技术人员变得清楚。
