摘要： A medical adapter having both a needleless valve and a sharpened cannula is used to connect or adapt pierceable septa containers or other devices having different sizes to needleless connection. The adapter includes a needleless site at one end and a sharpened cannula at the other end protected by spring arms. These arms include claws at their distal ends to grasp the neck of the pierceable septum device to which the sharpened cannula is to be inserted. The claws include sharpened points for gripping the device. The arms are located on either side of the adapter body and are connected to the body through springs. Handles are also included on the arms for use by the operator to separate the arms against the spring forces during engagement of the adapter with the septum. In one case, the handles include finger grips located above the springs for pressing the handles inward to open the arms and claws and in another case, the handles are located closer to the distal ends of the arms for pulling the arms outward. The adapter in one case comprises only three parts for reduced materials and manufacturing expense.

摘要： A modular patient care system is described having unique mechanical, electrical, and logical features. An apparatus is described for allowing a modular connection arrangement wherein modules are detachably connected to each other in a convenient, flexible, interchangeable, and secure manner by providing a hinge connector pair, a specially located latch mechanism, and a guide means between any pair of modules. Additionally, an apparatus and method is described for automatic, sequential, and dynamic logical address assignment of functional units attached to the central management unit, according to their respective position in a linear array of units. Logical address assignment is designed to occur automatically upon a physical reconfiguration of the functional units, without requiring external input or a rearranged scheme for determining the relative physical positions of the functional units.

摘要： A valve apparatus employs a spherical sealing element disposed in resiliently deformable tubing. The dimensions of the sealing element are selected such that the valve opens when subjected to a cracking pressure that is greater than the head pressure developed in an IV set and less than the pressure generated by a peristaltic pump. The valve additionally has an actuator element associated therewith that may be applied to the tubing about the sealing element to cause free flow without the need for continuous manipulation.

摘要： A system and method for communicating and validating patient information including medication delivery information in a care-giving facility is provided. A medical transaction carrier is used to communicate information regarding medication delivery and other patient information between a control system in communication with the care-giving facility's other information systems and a patient specific asset such as an infusion pump. All information carried by the medical transaction carrier is validated both at the patient specific asset and at the control system. This validation allows for positive control of all transactions even if a medical transaction carrier is lost. The medical transaction carrier may be a smartcard, a PDA such as a Palm™ Pilot, laptop computer, pager, mobile phone, or other device capable of storing and communicating information. The system may use either wired or wireless connections to communicate information between the components of the system.

摘要： A needle free medical connector includes a housing with a first port and a second port. The connector also includes a piston element defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has a compressible section having a variable inner width that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the compressible section self-expands in width thereby maintaining or increasing the volume of the fluid passageway through the connector. The compressible section has a configuration permitting the continuous flow of fluid through its entirety.

摘要： A needless valve is described which avoids the suctioning problems of the prior needleless devices upon deactivation and which preferably provides a positive self-purging effect. The valve is self-purging at the end of an administration cycle, avoiding clogging of attached catheters or other devices, and ensures that substantially all of liquid received into the valve is delivered to the receiver. The valve is also extremely simple in design and easy to construct and assemble, since it consists of only three pieces. The valve has a base with a connector for fluid communication attachment to tubing or other device, a solid elongated fluid channeling rod, and an internal fluid flow conduit; a flexible hollow expandable and contractible plug fitting over and moveable along the rod; and a tubular housing fitting over the plug and attached to the base. When the valve is activated by insertion of a nozzle of a fluid source, the rod and plug wall cooperate so that as the plug retracts along the rod, it is stretched and its interior expanded. Upon deactivation, the plug contracts, the interior volume decreases, and the resiling plug wall forces residual fluid within the valve to be expelled through the outlet, purging the residual fluid from the valve. No negative pressure is formed, so no suctioning of blood or other fluid from a patient or receiver occurs.
摘要翻译： 描述了不必要的阀，其避免了失活时先前无针装置的抽吸问题，并且其优选地提供正的自净化效果。 该阀在给药周期结束时自净，避免连接的导管或其他装置的堵塞，并且确保接收到阀中的基本上所有的液体被输送到接收器。 阀门设计也非常简单，易于构造和组装，因为它只包含三个部件。 该阀具有一个底座，该底座具有用于连接到管道或其他装置的流体连通的连接器，一个固体细长流体导流杆和一个内部流体流动管道; 柔性中空的可膨胀和可收缩的塞子装配在杆上并可沿着杆移动; 以及一个管状外壳配合在插头上并连接到基座上。 当通过插入流体源的喷嘴来激活阀时，杆和塞壁协作，使得当塞子沿着杆缩回时，其被拉伸并且其内部膨胀。 在停用时，塞子收缩，内部容积减小，并且回缩塞壁迫使阀内的残留流体通过出口排出，从阀门清除残余流体。 没有形成负压，因此不会发生来自患者或接收器的血液或其它液体的吸引。

摘要： Flow parameters in a fluid delivery assembly are determined by monitoring pressure responses and processing those responses along with information regarding the fluid flow. In one aspect, a processor controls the pump to pump flow quantities in accordance with a pseudorandom code. Portions of the resulting pressure signal sensed at the conduit is averaged, and the averaged values are then decoded in accordance with the pseudorandom code. An estimate of the equilibrium pressure is generated from the decoded average pressure values, while a summation of the pressure samples is generated from the undecoded pressure signals. The resistance to fluid flow of the system is determined from the estimated equilibrium pressure and pressure summation. For low flow rates, a processor controls the pump to pump fluid in a series of fluid boluses, with each fluid bolus delivered in the beginning of a separate timeslot. The equilibrium pressure is measured at the end of each timeslot, and a summation of the pressure samples is generated from the pressure signals. For high flow rates, the pump is controlled to vary the flow rate and the change in pressure is divided by the change in flow to directly determine the resistance. A resistance display continuously displays the resistance of the system. The pseudorandom coding and decoding can be used to filter out pressure-response crosstalk caused by multiple fluid infusion segments feeding into a common line.

摘要： A flexible tube occluder has a body portion and a slider portion which act to occlude a tube to prevent unwanted flow of fluid to a patient. The body portion and slider portion are engaged such that slider portion can move relative to body portion. The body portion extends the full range of slider portion's motion and thus the occluder allows for stable occluding and open positions. The slider portion has a slot of varying size which is used to occlude the tube by pressing the tube within the surface of the slot and to allow free flow of fluid through the tube.

摘要： An IV tube occluder is disclosed which has a bow portion and a linkage portion which act to occlude an IV tube to prevent unwanted flow of liquid to a patient. The linkage portion and bow portion are engaged to allow the ends of the linkage portion to rotate within a certain range. The linkage portion has an extending pinching member which is used to occlude a portion of flexible tubing by pressing the tube against the bow portion. The pinching member of the linkage portion moves against the bow portion through the provision of a hinge portion of the linkage portion, which allows the pinching member to hold the tube in an open or closed position. In an alternative embodiment, both the bow portion and linkage portion are formed as a continuous body.
