A system for filtering and processing blood that is simple to implement and that reduces the need for human intervention. The system may be used to collect red blood cells (RBCs). For such a system, a disposable set may be provided with an inlet port, an RBC container, a centrifuge rotor having a variable total volume, and a filter, along with tubing connecting the port, the container, the rotor and the filter. The filter is located in tubing between the inlet port and the rotor. A control unit is also provided and includes a spinner in which the rotor may be held, a flow-control arrangement for controlling flow among the various components of the disposable set, and an electronic controller. The whole blood is directed by the flow-control arrangement from the inlet through the filter to the rotor. The rotor includes an elastic diaphragm, and the control unit's flow-control arrangement includes a pump or other device for applying a positive and negative pressure to the rotor's elastic diaphragm. The spinner rotates the rotor so as to separate the whole blood into plasma and RBCs. Preferably, the plasma is urged out of the rotor first and returned to the donor, while the rotor is still being spun. After the plasma has been removed from the rotor, the RBCs are urged from the rotor to an RBC container. In preferred embodiments, the filter is a white blood cell filter, so that white blood cells are filtered from the blood before it reaches the rotor.

Disclosed are microbore catheters for spinal anesthesia having one or more side ports provided by a laser beam.

Microbore catheter with side port(s)

Disclosed is an article for use as a component part of a catheter system wherein a proximal section is exteriorized above the skin for connection to a liquid drug source, the article comprising a flexible sleeve having an advancement tip at its distal end to facilitate advancement of the sleeve into a passage beneath the skin created by tunneling the catheter subcutaneously to an exit site where the proximal end is exteriorized, the advancement tip having a generally bullet-shaped leading end and a base section having an outer diameter greater than the outer diameter of the sleeve, the advancement tip having a channel extending therethrough for receiving the catheter for passage through the sleeve; an adapter for placing the proximal end of the catheter in liquid communication with the drug source, the adapter having a channel extending longitudinally between the adapter ends, an opening at the distal end of the adapter communicating with the adapter channel and through which the proximal end of the catheter can be inserted, the proximal end of the catheter is releasably secured within the opening and in liquid communication with the adapter channel, and the proximal end of the sleeve is permanently attached to the distal end of the adapter with the sleeve surrounding the opening in the adapter so that a catheter extending through the sleeve may be introduced into the adapter opening to receive liquid drug passing therethrough.

Advancement sleeve and adapter for a catheter

A multilumen catheter having a distal portion with a soft tip and reduced cross-section. The multilumen catheter of the present invention includes a flexible, elongated first catheter tube and a flexible, elongated, dual-lumen catheter tube which has a first and second lumens integrally formed and is disposed within the first catheter tube. The cross-section of the dual-lumen catheter tube is smaller than that of the first catheter tube and therefore, an independent, single lumen is defined in the space between the first catheter tube and the dual-lumen catheter tube. The dual-lumen catheter tube extends beyond the distal end of the first catheter tube thereby providing an overall reduced cross-section of the distal portion of the present multilumen catheter. Furthermore, the dual-lumen catheter tube may be formed from a softer material than that of the first cathether tube thereby providing a softer distal portion of the present multilumen catheter. A protective hub encapsulates and secures the proximal ends of the first and dual-lumen catheter tubes, and facilitates fluid communication between each of the lumens and fluid transfer devices.

Multilumen catheter

An adapter kit 32 for a catheter introducer 31 wherein catheter 34 is passed into the body to transmit a medium through lumen 35 in catheter 34. Coupling means 95 is provided for compressing compression glands 48a and 48b against catheter 34 in a controlled manner in a catheter gripping position in FIG. 13, so that maximum resistance to catheter 34 pull-out is provided without distorting any medium transmitted by lumen 35. A related method is provided for sizing and using compression gland(s) 48.

A fluid sampling chamber assembly having a housing, a chamber within the housing for temporary storage of sample fluid and a pair of special sensor walls on opposite sides of the chamber for engagement by ultrasonic sensor probes. The sampling chamber is trough-shaped with an open top for both receipt and discharge of sample fluid. An inlet and outlet of the chamber housing are continuously open.

Sampling chamber assembly for in-line measurements of fluid within a

A liquid drainage system comprising a receptacle having a front wall, a back wall, and a chamber for collection of liquid therein. The system has a housing secured to an upper portion of the receptacle, said housing having a drip chamber, an annular wall in a lower portion of the drip chamber defining a valve seat, with said seat being disposed at an acute angle relative to the horizontal when the receptacle is in an upright position. The system has an anti-reflux valve comprising a sheet of flexible material having an upper portion and a lower portion and extending across said drip chamber such that the sheet is sufficiently large to engage against said seat peripherally around the drip chamber. The system has a device for retaining an upper portion of the valve against an upper portion of the seat, said valve being sufficiently flexible such that a lower portion of the valve flexes away from the seat when the receptacle is placed in an upright position due to gravity in the absence of liquid adjacent said valve and seat, and said lower portion of the valve flexes against the seat when the receptacle is disposed in a horizontal position.

Liquid valve system

A tamper-evident band for a liquid drainage system comprising an elastic catheter having an elongated shaft, a connector adjacent the proximal end of the catheter, and a drainage lumen extending through a major portion of the catheter and the connector. The tamper-evident band comprises elastomeric annular band of stepped diameter which is fit over the juncture between the connector and the proximal end of the catheter. The band has a slot longitudinally arranged on one outer peripheral portion of the band. It also has a semi-circumferential tear tab disposed on one end thereof. To separate the connector from the proximal end of the catheter, the band must be broken. The tab may be pulled and the band separated along its longitudinal slot. A small ring comprising the remaining stepped portion of the band remains on the adapter after the tab has been pulled, the slot fractured and the top band portion removed. This shows that there has probably been a band on the catheter and that the catheter has probably been separated from its connector.
