摘要:
A dynamic bushing and/or gripper mechanism comprises an apparatus for retaining a tubular member in a position during processing so that the tube does not move transverse to the longitudinal axis of the bushing, but wherein the tube may be rotated within the confines of the bushing and/or in the case of the gripper mechanism the tube may be moved longitudinally within the confines of the gripper.

A medication delivery system (20) having features of the present invention comprises a medical container (26) holding a prescribed medication (27) to be delivered to a patient, a tag 24 adapted to be worn by the patient, a handheld computing device (22), and an electronic medication delivery device (30). Data on the medication (27) is contained in a first label (28) on the medication container (27). The first label (28) also contains the instruction on how the medication is delivered to the patient, including the appropriate settings for an electronic medication delivery device for delivering the medication to the patient. Patient data is contained in a second label (29) on the tag (24) worn by the patient. The medication data, medication delivery instruction, and patient data are provided in machine readable formats. The handheld computing device (22) reads the medication data and the medication delivery instruction on the medication container (26) and the patient data on the patient tag (24). The handheld computing device (22) stores the information obtained and performs a matching check to confirm that the medication data matches with the patient data. Upon a confirmed match, it transmits the medication delivery instruction to the electronic medication delivery device (30), which downloads the instruction, programs the delivery device 30, and prompts an operator to begin delivering the medication (27) to the patient according to the downloaded instruction.
摘要:
A fluid flow control device comprises first second, and third fluid pathways. The first and second pathways are adapted for communication with separate sources of pressurized fluid. The third pathway is coupled in flow communication with the first pathway and includes a flexible wall which forms an interface with a portion of the second pathway. The flexible wall meters the flow communication between the first and third pathways in response to fluid pressure fluctuations in the second pathway. The fluid pressure in the first pathway is thereby elevated until substantial equilibrium with the fluid pressure in the second pathway occurs, and is thereafter continuously adjusted in response to subsequent fluctuations of fluid pressure in the second pathway to maintain this condition of substantial equilibrium.

摘要:
A flexible conduit coupled to a chamber of a weighing apparatus for conduiting fluid to the chamber, the conduit having a portion attached to a support spaced apart from the load cell chamber and being sufficiently arcuate in shape between the point and the load cell to substantially reduce relaxation and/or weight effects of the conduit on weight measurements. In a preferred embodiment, the arcuate portion forms a semicircular arch.
摘要:
A membrane plasmapheresis system introduces a flow of whole blood subject to a predetermined inlet pressure into a fluid path across a membrane which is suited for filtering the plasma from the whole blood and across which a predetermined pressure drop occurs. The plasma-poor blood is conducted from the membrane subject to a determinable plasma-poor blood pressure. Likewise, plasma filtrate is conducted from the membrane subject to a determinable plasma-filtrate pressure. The conduction of plasma filtrate is metered in response to the existent plasma-poor blood pressure to achieve and thereafter maintain substantial equilibrium between the plasma-poor blood pressure and the plasma filtrate pressure. A substantially constant transmembrane pressure can thereby be maintained at a level below which hemolysis occurs.
摘要:
A fluid flow control device comprises first, second, and third fluid conduits. The first and second conduits are adapted to communicate with separate sources of pressurized fluid. The third conduit includes an inlet portion in direct flow communication with the first conduit and an outlet portion communicating with the atmosphere. A flexible wall forms an interface between portions of the second and third conduits. In response to fluid pressure fluctuations in the second conduit, the flexible wall simultaneously meters the flow communication through both the inlet and outlet portions of the third conduit. The fluid pressure in the first conduit is thereby elevated until substantial equilibrium with the fluid pressure in the second conduit occurs.
