A portable traction device suitable for cervical or lumbar traction powered by a pneumatic cylinder. The portable traction device includes a support structure having a longitudinal axis and a carriage slidable along a portion of the support structure parallel to the longitudinal axis. The carriage including restraining mechanism for releasably restraining a portion of a patient's body to the carriage. A pneumatic cylinder includes a cylinder housing attached to the support structure. The cylinder housing contains a piston and piston rod. The piston rod is attached to the carriage for moving the carriage along the longitudinal axis relative to the support structure when pressurized air is injected into the pneumatic cylinder. The piston has at least one pressure activated seal extending circumferentially around the piston for engagement with an inside surface of the cylinder housing. A bicycle-style hand pump fluidly connected to the pneumatic cylinder is provided for injecting pressurized air into the cylinder.

The apparatus of claim 8, wherein said switch comprises a "no touch" contact and a "pull up" contact. 10. The apparatus of claim 1, further including a means for preventing said sample from reaching and contaminating said port for said fluid collector. 11. The apparatus of claim 1, wherein said port for said fluid collector includes at least one electrical connection. 12. The apparatus of claim 1, wherein said housing contains at least one latitudinal registration feature to position said fluid collector latitudinally. 13. The apparatus of claim 1, wherein said fluid collector comprises a biosensor. 14. The apparatus of claim 13, wherein said biosensor comprises a glucose detector. 15. The apparatus of claim 1, wherein said fluid collector comprises a reflectance strip. 16. The apparatus of claim 15, wherein said reflectance strip comprises a glucose detector. 17. The apparatus of claim 1, further comprising a reflectometer. 18. The apparatus of claim 1, further comprising electronics. 19. The apparatus of claim 18, wherein the electronics control power to said vacuum pump. 20. The apparatus of claim 18, wherein the electronics control power to the lancing assembly. 21. The apparatus of claim 1, wherein movement of said movable support is effected by a diaphragm. 22. The apparatus of claim 21 wherein said diaphragm is capable of being expanded by a pressure gradient. 23. The apparatus of claim 1, further including a power source. 24. The apparatus of claim 23, wherein said vacuum pump is operably connected to said power source. 25. The apparatus of claim 23, further comprising a display operably connected to said power source and said fluid collector. 26. The apparatus of claim 23, further comprising a switch operably connected to said vacuum pump and said lancing assembly through said power source. 27. A method for obtaining a sample of blood for a diagnostic test, said method comprising the steps of: (a) providing the apparatus of claim 1; (b) inserting a fluid collector into said support; (c) aligning said fluid collector latitudinally; (d) aligning said fluid collector longitudinally; (e) forming an unobstructed opening in the area of the skin from which said sample of blood is to be collected; and (f) collecting said sample of blood from said unobstructed opening in said skin, with the aid of vacuum and stretching of the skin. 28. The method of claim 27, further comprising the step of generating a signal indicative of glucose level. 29. The method of claim 27, further including the step of aligning said fluid collector longitudinally after step (e) and before step (f). 30. The method of claim 29, wherein said movement of said fluid collector is effected by a pressure gradient operating upon said movable support. 31. The method of claim 27, wherein steps (c) through (f) include the steps of: (i) placing said apparatus over a region on the surface of the skin from which said sample is to be obtained; (ii) forming a seal between said apparatus and said surface of the skin; (iii) creating a vacuum sufficient to result in said surface of the skin becoming stretched and engorged with blood; (iv) triggering a lancing assembly and causing a lancet to penetrate said skin; (v) retracting said lancet; (vi) withdrawing blood toward and onto a fluid collector; and (vii) releasing said vacuum. pressure/flow measurement for precise grading of bladder outflow obstruction," Abstracts of J.
