down the drain line when the rinse slide is activated both valves open and since the drain line is lower than the fluid source the fluid flows out of the drain line 18 the actuation handle 26 may then be squeezed with the fluid source 22 causing fluid to be pumped out of the fluid source 22 and through the drain line 18 cleaning the drain line 18 referring now to fig4 optionally the system may include an attachment mechanism 34 such as a belt clip for attaching the assembly 16 to the patient during use of the system now referring to fig4 and 5 a 5 c the attachment mechanism 34 may be coupled to the assembly 16 at an attachment location 36 the fluid source 22 may be coupled to the assembly 16 at an attachment assembly 38 fig6 a and 6b depict an alternative assembly 16 u2032 that may be used in place of the assembly 16 depicted in fig4 and 5 a 5 c in this embodiment an actuation lever 44 alternately either a opens a path between the patient line 20 and the drain line 18 or b closes the path between the patient line and the drain line.
