A system for delivering fluids which includes a pump (such as a peristaltic pump for example), a pump cartridge, a fluid reservoir, and a variety of fluid dispensers, including oral fluid dispensers. By providing a number of oral fluid dispensers, the one best suited for the needs of a particular application can be selected. The pump cartridge and/or the fluid dispensers may be disposable. The operation of the pump may be controlled based, at least in part, on the type of fluid dispenser being used. Further, a selectable mode can be used to further control the operation of the pump. The amount of fluids delivered over given periods of time may be monitored such that a reminder (such as an audio and/or visual alarm for example) may be provided if too much or too little fluid is delivered (and presumably consumed). The thresholds for such alarm conditions may be set and modified by a user. Further, the state of the fluid delivery system itself, as well as trends in fluid delivery, may be monitored.

An assembly for obtaining fluid from an opening formed in the skin of a patient comprising: (a) a device suitable for use in withdrawing fluid from an opening formed in the skin of a patient, said device comprising a hollow tube comprising a wall surrounding a cavity, said hollow tube having a first end and a second end, said wall running from said first end to said second end, said wall having a multiplicity of pores formed therein; (b) an elongated element capable of forming said opening in said skin, said elongated element capable of being inserted in said first end of said hollow tube and projecting beyond said second end of said tube. 2. The assembly of claim 1, wherein said wall of said tube comprises a polymeric material. 3. The assembly of claim 1, wherein said tube has a length ranging from about 2 mm to about 10 mm. 4. The assembly of claim 1, wherein said tube has a length ranging from about 5 mm to about 10 mm. 5. The assembly of claim 1, wherein said tube is cylindrical in shape. 6. The assembly of claim 5, wherein the inside diameter of said tube is at least about 0.25 mm but the inside diameter of said tube does not exceed about 1.25 mm. 7. The assembly of claim 5, wherein said tube has an outside diameter ranging from a minimum outside diameter of about 0.45 mm to a maximum outside diameter of about 2.25 mm. 8. The assembly of claim 5, wherein a maximum pore size is less than the inside diameter of the tube. 9. The assembly of claim 1, wherein said tube is in the shape of a parallelepiped. 10. The assembly of claim 1, wherein said wall of said tube has a porosity of from about 1% to about 10%. 11. The assembly of claim 1, wherein the number of pores per mm of tube length ranges from about 10 to about 10,000. 12. The assembly of claim 1, wherein a maximum pore diameter does not exceed 1 mm and a lower limit of pore diameter is not less than 5 micrometers. 13. The assembly of claim 1, further including a patch bearing a layer of adhesive on one major surface thereof for adhering said assembly to said skin. 14. The assembly of claim 1, further including a holder for said elongated element. 15. The assembly of claim 1, further including guides for aligning a detector holder. 16. A method for obtaining interstitial fluid from the body of a patient, said method comprising the steps of: (a) providing the assembly of claim 1, said tube surrounding said elongated element; (b) inserting said elongated element and said tube surrounding said elongated element into said body of said patient; (c) removing said elongated element from said cavity of said tube; and (d) collecting interstitial fluid from said body of said patient, said interstitial fluid exiting from said first end of said tube. 17. The method of claim 16, further including the step of determining the blood glucose level from said collected interstitial fluid. 18. The method of claim 16, wherein said interstitial fluid is collected with the aid of vacuum.
