摘要： A valve that has at least one internal port on a valve core and at least one an internal slot in a valve body. The valve core is biased into a position wherein the port of the valve core is aligned with a sealing surface of the valve body thereby prohibiting fluid flow through the valve. The valve core is slidable such that the port of the valve core becomes aligned with the internal slot of the valve body thereby allowing fluid flow through the valve. Another valve includes a self-aligning valve seat carrier which is pivotably engaged with a valve core member. The self-aligning valve seat carrier engages a sealing surface in a valve body to prohibit fluid flow through the valve, but the valve core is slidable such that the self-aligning valve seat carrier disengages from the sealing surface in order to allow fluid flow through the valve.

摘要： A needleless IV injection port assembly includes a spiked body provided with a hollow spike, a female luer component, a flexible and resilient spike boot having a tip and spring portion, a centering member, and a resilient swabbable septum. The spike boot extends over the spike, the centering member is provided over a portion of the spike and spike boot, and the septum is provided between the centering member and an end of the female luer component. The spiked body and the female luer component are secured together to complete the assembly. The length of the female luer component and/or the length of the spike is chosen so that when a separate male luer is positioned over a protuberance on the septum and pushed into the female luer component, the male luer places pressure upon the septum which thereby urges the septum toward the spike. The pressure on the septum causes the spring portion of the boot to be compressed and the tip portion of the boot to be pierced by the tip of the spike. As the septum is further compressed, the septum extends over the spike, with a pre-slit hole in the septum facilitating the extension thereover, such that a hollow of the spike is in fluid communication with the male luer connector. The injection port causes minimal reflux, and the spike boot and septum provide a swabbable antibacterial double barrier over the spike.

摘要翻译： 无针IV注射口组件包括设置有中空尖钉的加标体，阴性鲁尔部件，具有尖端和弹簧部分的柔性和弹性尖头护套，定心构件和弹性可擦拭隔膜。 尖钉靴在尖头上延伸，定心构件设置在尖钉和尖钉靴的一部分上，并且隔膜设置在定心构件和母路厄构件的端部之间。 加标的身体和女性鲁尔部件固定在一起以完成组装。 选择女性鲁尔部件的长度和/或尖头的长度，使得当单独的公路厄尔位于隔膜上的突起上并被推入阴性鲁尔部件中时，阳性鲁尔器将压力施加在隔膜上，由此 敦促隔垫朝向尖峰。 隔垫上的压力使得护罩的弹簧部分被压缩，并且护套的尖端部分被尖钉的尖端刺穿。 当隔膜被进一步压缩时，隔膜在尖头上延伸，隔膜中的预狭缝孔有助于其延伸，使得尖端的中空与阳性鲁尔连接器流体连通。 注射口导致最小的回流，并且尖头靴和隔膜在穗上提供了可以吸收的抗菌双重屏障。

摘要： A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container.
