具体实施方式
本发明在其一些实施方式中涉及用于通过偏转尖端防止针的尖端再暴露的系统和方法,并且更具体地但不排他地,涉及用于当针保护器翻板塌陷时偏转和/或封闭尖端的引导件和/或安全夹。
便携式药泵可以包括用于覆盖突出的针的保护翻板。在某些条件下,保护翻板可以塌陷,从而再暴露针。在一些实施方式中,本发明可以包括用于将针偏转至安全空间的可选的引导件,从而防止在翻板塌陷情况中针的再暴露。可选的封闭件可以遮蔽安全空间。
在一些实施方式中,在保护位置中,当翻板在保护位置时,引导件可以布置倾斜向针的斜面处。包括在偏转引导件和针之间的角度可以确定当翻板塌陷时尖端偏转的方向。在针和偏转引导件之间的角度可以在5°至85°之间是可选的。引导件可以是平板的形式,和/或引导件可以包括或用于将针尖引导至安全空间的壁和/通道,和/或引导件可以具有用于引导针尖的凹形。
在一些实施方式中,偏转尖端将包括弯曲针。另外地或可替换地,偏转尖端可以包括枢转针和/或引起针的支撑件的平移。
在详细解释本发明的至少一种实施方式之前,应当理解本发明不必要地将它的应用限制于在以下描述中阐明和/或在附图和/或实例中示出的构造的细节与部件的布置和/或方法。本发明能够有其他实施例或能够通过不同的方式实践或实施。
图1a是示出了用于当保护翻板受到塌陷故障时防止尖端再暴露方法的简化实例的流程图。例如,这类故障可以来自于对翻板的强烈撞击。
例如,注射设备可以由需要通过皮下注射接收药的患者使用。患者可能更喜欢在家使用注射设备接收注射而不是去往医生处。接受者可以通过可选地将设备附接162至他的身体而佩带注射器。附接162可以是,例如,通过在注射器的底座上的粘合剂。
在一些实施方式中,在附接162之后,可选地注射器可以皮下地插入164皮下注射针头至接受者。然后,注射设备可以通过针可选地注射166药至接受者。在注射166之后,患者可选地移去168注射设备。
在一些实施方式中,在移去168之后,针将保持从注射设备突出,呈现针刺危险。为了保护人们免受针的危害,注射设备可以可选地包括用于覆盖170针的保护翻板。
当翻板在保护位置中时,一些时候,强力可以塌陷172保护翻板。例如,患者可以将设备扔进垃圾箱,并且然后用他的脚随后紧压垃圾。紧压力可以塌陷注射设备的保护翻板,可能再暴露针的尖锐的尖。
在一些实施方式中,翻板可以包括可选的故障安全引导件,以在翻板塌陷172情况中防止针的再暴露。引导件可以将针的尖端可选地偏转174至安全空间中,从而降低针刺伤害的可能性。
图1b是示出了包括可选的步骤避免针刺的方法的流程图。避免针刺的方法可以包括一种、一些或所有可选的步骤。
注射设备提供在保护170’位置中,在该保护位置中,针保护翻板覆盖尖端。当强力塌陷172’保护翻板时,尖端被可选地偏转174’至安全空间内。
在图lb的示例性实施方式中,尖端可以可选地在于针尖上。在偏转174’期间,针可以可选地被弯曲176。可替换地或另外地,针可以安装在可移动的支撑件上并且当偏转174’尖端时针可以枢转和/或平移。
在一些情形中,护罩(例如夹)可以包含在注射器中以用于遮蔽178安全空间。遮蔽178安全空间可以防止针刺,例如,通过弯曲和/或枢转和/或平移,当翻板折断和/或人将他的手指推在翻板下时,和/或当翻板的位移未覆盖针时,和/或当尖端从翻板下方移开时。可替换地或另外地,针和/或引导件和/或夹可以将针保护翻板保持180在关闭位置中,从而利用翻板遮蔽178针。
图2a、2a’、2b、2c、2c’、2d、3a、3b、3c、3d、3d’、4和4’是便携式药注射器设备以及针保护翻板222的示例性实施方式210的视图。在实施方式210中,翻板222可选地枢转地安装至设备壳体的底座。
图2a-c是针保护器在多个位置中的简化示意图。具体地,图2a、a’示出了在暴露位置中的注射器和翻板,其中,针216是暴露的。例如,在图2a中,翻板222示出在暴露位置中,同时设备将药注射到接受者的肉体内。图2b示出了在保护位置中的注射器。图2c、c’示出在保护翻板222塌陷之后的注射器。具体地,图2c’示出了安全空间256和用于将针216的尖端232偏转至安全空间中的引导件252。图2也示出了遮蔽安全空间256的可选的夹254。
图2a、a’示出了在暴露位置中的保护翻板222(例如,同时将药注射到患者体内)。在图2a中,实施方式210示出为附接至接受者。针216从在翻板222中的针开口229突出并且插入到肉体205内。在注射期间,注射器的底座通常通过粘合剂保持抵靠着接受者的皮肤。在暴露位置中,翻板222通过抵靠着接受者皮肤的压力可选地保持与注射器壳体的底座平齐。针216可选地锁定在突出位置中。药可以给予接受者,例如,通孔针216和/或套管。
本发明的实施方式仅参考针描述,但是针较好地应用于布置在套管或任何其他传输装置中的针。贯穿说明书和权利要求使用的术语“针”包含所有这类传输装置和/或尖锐的器具。
实施方式210通常包括在设备的壳体内的电动机、电池和控制单元(所有都未示出)。在针216刺穿患者皮肤之后,控制单元控制电动机的运行,从而以控制的传输速度给予患者控制的量的物质。当然,本发明的针组件可以用于其他应用中并且不必与控制的马达传动的传输系统一起使用。
当完成注射时,注射器提升并离开接受者的皮肤,翻板222从装置底座枢转至所示出的保护位置,例如,在图2b中(并且更详细地在图3a-c中)的保护位置。在保护位置中,翻板222覆盖针216的尖端,保护人们免受针刺危害。
关注的是如果翻板222以足够的力向后枢转注射器壳体从而弯曲针216,然后尖端232可以再暴露而生成针刺危害。例如,在图2b和图2c中,如果针216向左弯曲至在翻板222和壳体之间的开放空间而没有任何保护的机构,则人可能被针刺,如果他将他的手指推在翻板下方,如图2c所示。实施方式210包括引导件和夹,以偏转并且遮蔽针216并且防止例如,如图2c’示出的这类针刺。
图2c’是翻板222的示例性实施方式的放大切开视图。具体地,图2c’示出了在翻板222的塌陷情况中防止针216再暴露的可选的引导件252和可选的夹254和可选的安全空间256。具体地,当翻板222塌陷时,引导件252将针216推到安全空间256内。可选地,夹254遮蔽安全空间256。(参考图4和图4’,参见引导件252、夹254、和空间252的示例性实施方式的以下更详细的论述。)
图2d示出了翻板222的透视图。
在图3a-c中,示出的实施方式210在保护位置中。在完成药供给之后,实施方式210通常提升并离开接受者的身体。随着注射器提高,偏置装置227将翻板222从设备的底座推开。翻板222枢转到保护位置中。在图3a-c中,示出的翻板222在保护位置中,并覆盖着尖端232。
例如,如图3c所示,随着翻板222从暴露位置(图2a、a’)移动至保护位置(图2b、3a-c),针开口229可选地跟随弧形轨迹330(在图3c中向下并且向右)。随着开口229沿着轨迹330移动,针216可选地向右弹性地弯曲。当开口229经过尖端232下方时,针216可选地弹回向左至它的无应力形状。例如,如图3c所示,在它的无应力形状,针216可选地保持锁定成突出离开壳体。针216不再与针开口229对齐。针216可选地用作支柱,防止翻板222返回至暴露位置。翻板222用做阻挡尖端232的保护器。
在图3d、d’中,可以看出,在示例性实施方式210中,开口229可选地是非圆形的。在一些实施方式中,可以将针开口229的形式选择成用于调整翻板222从暴露位置(图2a、a’、3d、d’)枢转至保护位置(图3a-c)的阻力。另外地或可替换地,可以将针开口229的形式选择成用于调整翻板222在保护位置中的稳定性。
在实施方式210中,开口229可选地包括线性管道240。在实施方式210中,管道240可选地指向与翻板222的枢转轴线242呈接近于55°的角度220。
在示例性实施方式210中,随着翻板222从暴露位置(例如,如图2a、a’、3d、d’所示)枢转至保护位置(例如,如图3a-c所示),针216沿着管道240滑动弯曲,以保持在开口229中。一旦翻板222枢转足够远,则尖端232穿过开口229并且针216返回至它的无应力形状(例如,如图3c所示)。
在实施方式210中,随着针216需要的弯曲增加,翻板222枢转的阻力可能增加。针216需要的弯曲可以取决于管道240的长度和角度220。通常,随着角度220从0°增加至90°,阻力可以降低。
在实施方式210保护的模式中(图3a-c),尽管尖端232不与开口229对齐,但是针216作为支柱以稳定翻板222。随着角度220从0°增加至90°,尖端232无意地与开口229再对齐的可能性可能增加。
可选地,角度220可以在5°和85°之间变动。在许多实施方式中,角度220可以在40°和80°之间变动。在一些实施方式中,管道240可以是弧形的和/或具有非均一的宽度。可选地,开口229可以具有不同的形式。更普遍地,针216需要的弯曲可以取决于在针216的无应力位置与在最大弯曲尖端处之间的针216和开口229之间的接触点之间的角度和距离。更普遍地,在保护位置中,在针216和开口229之间的无意对齐的可能性可以取决于在保护位置中在尖端232的无应力位置和开口229最近边缘之间的距离。
图3c示出了可选的引导件252和可选的封闭件、安全夹254的示例性实施方式。引导件252可选地整合到翻板222中。例如,引导件252可以附接至翻板222和/或它可以整合至翻板222。
在一些条件下,翻板222可以塌陷。例如,强力可以引起翻板222塌陷并且朝向设备的底座枢转。随着翻板222枢转,引导件252将尖端232偏转至夹254的安全空间256(如图4和图4’所示),以防止针刺危害。
在一些实施方式中,夹254可选地遮蔽安全空间256。另外地或可替换地,夹254可以抓紧尖端232。
在图3a-c的保护位置中,引导件252可选地布置成与针216和尖端232的轴线呈接近于45°角度318。在一些实施方式中,引导件可以相对于尖端232布置为5°和85°之间变动的角度318。
图4示出了在翻板222塌陷之后的实施方式210。图4’示出了圆形B的放大图。在图4和图4’中,引导件252将尖端232偏转至保护的安全空间256内。在实施方式210中,引导件252可选地配置成,使得偏转在沿远离在翻板222和注射器壳体之间的接头的方向上。在替换的实施方式中,针可以朝向接头偏转和/或相对于枢转连接呈角度地偏转。
在一些实施方式中,夹254可以可选地配置成用于抓紧弯曲的针216,从而确保保护翻板222在关闭位置中。在关闭位置中,翻板222可以遮蔽尖端232。在一些实施方式中,夹254可以将尖端232保留在安全空间256的内部。例如,夹254可以抓紧针216和/或尖端232(利用抓紧力)。可替换地或另外地,夹254可以封闭并且遮蔽尖端232,但不紧握针216或尖端232。
夹254和/或引导件252的组分可以包括塑料、金属、纸、木头和/或另一个适宜的材料。
图5a、b示出了设备的另一个示例性实施方式510。在实施方式510中,当可选的保护翻板522的塌陷时,针516枢转到安全空间556内。
在实施方式510中,针516可选地安装在枢转支撑件558上。图5a示出了在保护位置中的实施方式510。图5b示出了在翻板522塌陷之后的实施方式510。
在图5a中,尖端532通过翻板522被覆盖。可选的引导件552相对于尖端532以角度518可选地倾斜。翻板522通过可选偏置装置527并且通过针516保持在保护位置中。
在一些条件下,可以迫使翻板522向后枢转至设备的底座。随着翻板522枢转至设备的底座,引导件552将尖端532偏转至安全空间556内。首先,枢转支撑件558允许针516枢转而不用弯曲。随着翻板522进一步塌陷,如图5b所示,尖端532与可选的夹554的后侧碰撞以迫使针516弯曲。
图6a、b示出了根据本发明的具有故障安全针保护器设备的另一个示例性实施方式610。可选地,在实施方式610中,当翻板622塌陷时,尖端632偏转到在设备的翻板622和壳体之间的接头处形成的安全空间656内。
在图6a、b中,针616安装在可选的滑动枢转支撑件658上。支撑件658的枢转和平移允许尖端632偏转到安全空间656中而不用弯曲针616。
图6a示出了在保护位置中的实施方式610。图6b示出了在可选的保护翻板622塌陷之后的实施方式610。
在图6a中,尖端632由翻板622覆盖。翻板622通过最佳的偏置装置627并且通过针616保持在保护位置中。可选的引导件652相对于尖端632以一种角度618可选地保持倾斜。在实施方式610中,引导件652的倾斜与翻板622的倾斜可选地相对。
有时可能迫使翻板622向后枢转至设备的底座。随着翻板622向后枢转至设备的底座,引导件652将尖端632偏转远离在设备的翻板622和底座之间的开口。尖端632偏转至由在翻板622和壳体基座之间的接头形成的安全空间656。支撑件658可选地沿着可选的轨道660枢转并且平移,以允许针616朝向安全空间656枢转。随着翻板622继续塌陷,尖端632被引导件652推动。最终,针616枢转而不用弯曲直至它抵靠与设备的底座并行的引导件652平躺。在图6b中,尖端632位于由设备的底座和翻板622遮蔽的安全空间656中。
图7是保护翻板722的另一示例性实施方式的放大透视图。在附图中可见的是枢转轴线742和针开口729和引导件752和遮蔽夹754和安全空间756以及偏置元件727的示例性实施方式。实施方式722也包括形成用于在翻板722的塌陷期间防止针侧向扭曲的通道的屏障件762。
图8是引导件852的示例性实施方式的放大透视图。在附图中可见的是针开口829和遮蔽夹854和安全空间856和用于将针的尖端引导至安全空间856和/或在保护翻板的塌陷期间防止针侧向扭曲的通道860。可替换地或另外地,通道860可以具有非矩形形状(例如,它可以具有楔形形状)。可替换地或另外地,通道860可以具有非矩形横截面(例如,它可以具有V形横截面)。可替换地或另外地,通道860可以由凹形引导件856形成。
