Benefits of technology
[0013] It is an object of the present invention to overcome the drawbacks of the prior art, particularly to provide a cost effective portable fluid provider that enables quiet operation in a compact space without incurring the risk of overheating. It is another object of the present invention to provide a portable fluid provider system that enables interconnection with a plurality of other fluid providers to maximize the final fluid output pressure and volume fed into a single filling port on a transfer device.
Problems solved by technology
From industrial to medical settings, it is often impossible to move an object (load) or person without the aid of a transfer device to assist in the transport.
Patients who cannot by themselves sit up or move can be particularly difficult to move from a stretcher to a bed or vice versa, and repositioning such patients frequently requires two or three people (e.g., nurses, orderlies or other attendants).
That situation is not desirable, however, as it naturally gives rise to the possibility that the medical personnel themselves will incur back or other injuries, particularly if the patient is unusually heavy or completely immobilized.
Notwithstanding the painful nature of the injury itself, such medical personnel injuries can also result in lost time and workers compensation claims.
Another situation calling for the aid of a transfer device involves moving bulky and / or heavy industrial loads.
There are some situations, however, where hoisting, conveyor transfer or ordinary pallet and fork truck transfer is not possible or practical.
For example, fork trucks cannot practically be used in residential settings to remove old appliances, such as refrigerators and washing machines and the like, or reposition new appliances.
Moreover, moving furniture, even over short distances within a room or building, can damage both the furniture and the floor.
Although conventional small pumps / compressors can be carried about fairly easily, problems exist in using these conventional pumps / compressors in connection with the inflatable transfer devices described above.
One problem is that the air compressors must be small in order to be deemed “portable.” Small air compressors or fluid pumps have a reduced capacity to provide pressurize fluid to a transfer device.
This problem is particularly troublesome when the load is very large or heavy and a significant amount of pressure is needed in order to inflate the transfer device.
This arrangement, however, limits the effective portability and reduces the maneuverability of the transfer device since a multiple number of individually powered units are required to be connected at multiple positions around the transfer device.
Another problem is that the pump or air compressor must be oriented in a specific position, particularly so that air can be accepted into the unit and such that the unit can operate without overheating.
This orientation, how ever, requires more lateral space, and access to typically side-mounted operational controls, connections and power supply ports can be inconvenient.
Yet another problem is that typical air compressors and fluid pumps tend to generate a great deal of noise during operation, which is particularly undesirable in a hospital or nursing home setting.
Conventional methods for damping sound, such as covering the loud air compressor or fluid pump with a blanket, pillow or otherwise physically muffling the loud sounds emitted therefrom, tend to induce the risk of overheating and inhibit the ability of air to properly flow into the compressor.

Embodiment Construction
[0047]FIGS. 1-6 are various non-perspective views showing an embodiment of a vertically oriented fluid provider according to the present invention, and are best read in conjunction with the perspective views shown in FIGS. 7 and 8. The elongate fluid provider housing 100 includes an intake end 10 and an opposed output end 40. A fluid pressurization unit 50 (see FIG. 7) is positioned within the housing 100 proximate the intake end 10. The fluid pressurization unit 50 is spaced a distance from the intake end 10, and an intake shield 51 is interposed therebetween. A motor unit 60 (not shown) is positioned within the housing 100, interposed between the fluid pressurization unit 50 and an output shield 45 located proximate the output end 40 (see FIG. 8).
[0048] A plurality of flat surfaces 110, 111 are provided on exterior portions of the fluid provider housing 100, which is otherwise substantially cylindrical in shape. These flat surfaces 110, 111 can be provided with a variety of attac...

A fluid provider assembly including a fluid provider housing having an intake end having a fluid intake vent and an opposed output end having a fluid output vent. A motor unit is positioned within the housing, and a fluid pressurization unit is interposed between the intake end and the motor unit for pressurizing fluid within the housing such that fluid expelled from the output vent has a higher pressure than fluid received through the intake vent. A portable sound damping case is also provided. The case has a base side, peripheral sidewalls, and a closeable top side. The base side has a fluid intake vent in a first position laterally spaced from a center point of the base. The intake end of the fluid provider assembly is positioned proximate the base of the case such that the fluid provider assembly intake vent is laterally offset from the first position.
Description
BACKGROUND OF THE INVENTION [0001] The present invention relates generally to fluid providers, and more particularly to a portable fluid provider system for receiving fluid, pressurizing fluid, and transporting the pressurized fluid into a fluid containing member. [0002] The need to translocate large yet delicate or heavy objects without damaging the object or the transfer surfaces spans the gamut of practical applications. From industrial to medical settings, it is often impossible to move an object (load) or person without the aid of a transfer device to assist in the transport. [0003] One application example includes moving medical patients, such as accident victims, the elderly, or comatose, paralyzed or otherwise immobilized patients, who are frequently difficult to transfer or move in a safe, comfortable manner from one support surface, such as a bed, to another support surface, such as a gurney or wheeled hospital cart. Patients who cannot by themselves sit up or move can be ...
