Four models of apparatuses and their variants are presented. All of them have multiple reservoir cells, a pump, a pump controller, one or more batteries on a flexible pad so that the apparatuses can be adhesive to the user's skin as a big and thick Band-Aid. The user will feel comfortable when he or
Four models of apparatuses and their variants are presented. All of them have multiple reservoir cells, a pump, a pump controller, one or more batteries on a flexible pad so that the apparatuses can be adhesive to the user's skin as a big and thick Band-Aid. The user will feel comfortable when he or she bends his to her body. The first model, each reservoir cell contains a medicine bag that contains the medicine. The rest space of the reservoir cells contains the air. Pumping the air into the reservoir cells will press out the medicine from the medicine bags into the user's body. The second model, each reservoir cell contains the medicine and an air bag. Pumping air into the air bags will press out the medicine from the reservoir cells into the user's body. The third model is similar with the second one where the medicine is drawn from the reservoir cells and pressed into the user's body. The forth model is similar with the first one where the medicine is drawn from the medicine bags and pressed into the user'body. The motor and the associated parts is small, simple; and light. The reservoir cells can be small and, hence, the apparatus is thin. Separating the monitor and controller from the apparatus, the apparatus that is attached to the user's skin is even smaller and lighter. Hence, the user will feel much more convenient than using conventional ones.

A method according to claim 28, wherein the atmospheric vent is disposed proximate to the endoscope so that the introduction of atmospheric pressure into the first line increases the pressure at an outflow connector of the endoscope. 30. A method of managing patient fluid, the method comprising: providing a fluid management assembly comprising first, second, and third lines, the first line defining a passage for the flow of fluid from an operative site after the fluid has been delivered to the operative site at a first pressure, the fluid flowing from the operative site at a second pressure, the third line having a length that is less than a length of each of the first and second lines; attaching an endoscope to a first end of the first line; attaching a second end of the first line to an input port of a Y-connector; attaching a drape to a first end of the second line, with a second end of the second line being attached to another input port of the Y-connector; attaching one end of the third line to an outlet port of the Y-connector and another end of the third line being attached to a suction source; disposing an atmospheric vent within the first line; and introducing atmospheric pressure into the first line when internal pressure within the first line is less than a predetermined pressure and in the case that the internal pressure is greater than the predetermined pressure, the method further including closing the atmospheric vent. 31. A method according to claim 30, wherein the predetermined pressure is atmospheric pressure. 32. A method of managing patient fluid, the method comprising: providing a fluid management assembly comprising a first line defining a passage for the flow of fluid from an operative site after the fluid has been delivered to the operative site at a first pressure, the fluid flowing from the operative site at a second pressure; attaching an endoscope to a first end of the first line; connecting one of a suction source and a drape to a second end of the first line; disposing an atmospheric vent within
