Continuous spinal anesthesia administering apparatus

A continuous spinal anesthesia administering apparatus is disclosed which comprises a polymeric microcatheter having an external diameter less than about 0.0130 inch (0.330 mm) with a reinforcing stylet therein. A method for administering anesthesia to a patient utilizing this apparatus is also disclosed, as is a catheter kit containing this apparatus.

Continuous spinal anesthesia administering apparatus and method

An adaptive connector assembly for engaging a catheter or the like comprises a pair of segments adapted for telescoping engagement with one another so as to develop a centrally disposed cavity for receiving a plug formed of a compressible material. An end of one of the segments has an opening which communicates with the cavity and which is adapted to receive the catheter therein. The plug also has a centrally disposed channel for receiving the catheter from the opening. A snap-fit engagement is developed between the telescoping segments so that when the telescoping segments are engaged, the plug is placed in compression, constricting the channel about the catheter and thereby engaging the catheter within the adaptive connector assembly.

Connector assembly

A collapsible medical agent container (10) is disclosed having walls (34, 36, 38) defining a plurality of chambers (12, 14) for containing selected quantities of one or more medical fluids or a dry or encapsulated drug or other reagent in separate sealed condition. Opening means which communicates between adjacent chambers (12, 14) for passage of fluid from one chamber to another, is normally closed by frangible closure (18) which maintains the chambers (12, 14) in separate hermetically sealed condition until flow between the chambers (12, 14) is needed. The frangible closure (18) has an elongated relatively rigid portion (20) which extends into one of the chambers and is disposed within a protective retentive tube (24), and a relatively weakened portion (22) adjacent the opening means. The closure (18) is manually openable from exterior the container (10) to permit flow between the chambers (12, 14), such as for mixing, by grasping the elongated portion (20) through the walls (30, 32) of the container (10) and bending it until the relatively weakened portion (22) is fractured.

Collapsible multi-chamber medical fluid container

A process and apparatus for mixing at least two parenteral solutions, sterilizing the resulting mixture, and transferring the sterilized mixture into an extensible, plastic receiving bag. The apparatus includes a mixing chamber into which the solutions can be delivered, a bacterial organism retentive filter for sterilizing the mixture of the solutions received from the chamber, such a receiving bag, tubing for transferring each of the solutions to be chamber, and second tubing for transferring the sterilized mixture from the filter to the bag. All are combined and then sterilized as a unit. In one embodiment of the invention, the bag is placed in a vacuum chamber to facilitate transfer of the mixture through the apparatus and the mixing chamber has a baffle or system of baffles for creating turbulence in the solutions while they are being mixed. The diameter and length of each tubing leading into the chamber from a solution holding container is preselected with respect to the viscosity of the solution in that holding container, so that both solutions reach the chamber at the same time or in a selected order and are mixed in an equal or preselected proportion therein.

Process and apparatus for compounding hyperalimentation solutions

An enteral feeding container having a relatively enlarged port and closure which is resistant to popping open upon dropping. The enteral container may have a tapered portion for improved accuracy of administration.
