Pneumatic medical system

4) A pneumatic medical system, usable in connection with a hand, having fingers and a thumb, comprising, in combination:

• a) at least one container, graspable by the hand, adapted to contain fluid;
• b) at least one first passage and at least one second passage structured and arranged to define a path of pressurized fluid through said at least one container;
• c) at least one modulator adapted to modulate, by use of the thumb, a force of the pressurized fluid through said at least one container;
• d) at least one integral cap adapted to cap said at least one container;
• e) wherein said at least one integral cap comprises said at least one modulator.

18) A pneumatic medical device, usable in connection with a hand, having fingers and a thumb, for use with at least one container having a substantially vertical central longitudinal axis and structured and arranged to contain a fluid, comprising:

• a) at least one integral cap, structured and arranged to cap the at least one container, and comprising:
• i) at least one first passage and at least one second passage, structured and arranged, with the at least one container, to define a path of pressurized fluid through the at least one container;
• and
• ii) at least one modulator adapted to modulate, by use of the fingers or thumb, a force of the pressurized fluid through said at least one container.

31) A pneumatic medical system comprising:

• a) at least one smaller-diameter catheter;
• and
• b) at least one larger-diameter catheter;
• c) wherein at least one of said at least one smaller-diameter catheter and said at least one larger-diameter catheter comprises at least one flexible catheter;
• d) wherein said at least one smaller-diameter catheter is releasably connected, via an airtight frictional fit, within said at least one larger-diameter catheter;
• e) wherein said at least one smaller-diameter catheter and said at least one larger-diameter catheter each comprise a proximal and a distal end;
• and
• f) wherein said distal end of said at least one smaller-diameter catheter extends beyond said distal end of said at least one larger-diameter catheter.

32) A pneumatic medical system comprising, in combination:

• a) at least one source of oxygen under pressure;
• b) at least one container adapted to contain irrigation fluid;
• c) wherein said at least one container comprises at least one inlet adapted to inlet such oxygen under pressure from said at least one source into an interior upper portion of said at least one container;
• and
• d) wherein said at least one container comprises at least one outlet adapted to outlet such irrigation fluid from an interior lower portion of said at least one container;
• and
• e) at least one connector adapted to connect said at least one source with said at least one container in such manner as to assist forming a passageway for such oxygen under pressure from said at least one source to enter said at least one inlet;
• f) wherein, when said at least one container contains such irrigation fluid and when such oxygen under pressure enters said at least one container, such irrigation fluid will expel through said at least one outlet and thus be available for irrigation use.

34) A pneumatic medical system comprising the steps of:

• a) providing a sealed container of irrigation fluid, such container comprising at least one unsealable inlet and at least one unsealable outlet;
• b) unsealing such container by unsealing such at least one unsealable inlet and such at least one unsealable outlet;
• c) connecting such unsealed at least one unsealable inlet with a source of oxygen under pressure;
• and
• d) using the irrigation fluid expelled from such container when oxygen enters such unsealed at least one unsealable inlet for irrigation.
