DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved fluid administration system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the fluid administration system 10 is comprised of a plurality of components. Such components in their broadest context include a needle, a pump and a haptic feedback device. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
First provided is a needle 14. The needle has a distal extent. The needle has a proximal extent. The needle also has an intermediate extent. The intermediate extent is provided between the distal and proximal extents. The distal extent has a patient-injecting point 16. The proximal extent has an electrical assembly 18. A passageway is provided through the proximal extent. In this manner anesthetic fluid may flow through. The intermediate extent has a hollow linear feed path 20. The hollow linear feed path is provided for the anesthetic fluid.
A pump 24 is provided. The pump has a reservoir 26. The reservoir is adapted to receive and dispense anesthetic fluid. A feed tube 28 is provided. The feed tube operatively couples the reservoir of the pump and the proximal extent of the needle. The electrical assembly has a button 30. The electrical assembly also has a foot pedal 34. Primary electrical lines 32 are provided. The primary electrical lines operatively couple the electrical assembly and the pump. The button and/or the foot pedal is adapted to be depressed by the care giver. In this manner, the pump is activated. Further in this manner a flow of anesthetic fluid is fed from the reservoir to and through the needle and into the patient.
Provided next is a haptic feedback device 36. The haptic feedback device has secondary electrical lines 38. The secondary electrical lines operatively couple the haptic feedback device and the primary electrical lines. The haptic feedback device has tertiary electrical lines 40. The tertiary electrical lines operatively couple the haptic feedback device and the electrical assembly. The haptic feedback device is adapted to sense the flow of anesthetic fluid through the electrical assembly. The electrical assembly has a sensory signal generator 42. In this manner the sensory signal generator is activated in response to the sensed flow of fluid through the electrical assembly. The sensory signal generator being chosen from the class of sensory signal generators include a tactile vibrator and an audio buzzer and a visual blinker and an applied force generator. The term applied force generator is meant that when the care giver pushes on the haptic feedback device, he or she is able to feel an applied force back against the finger to the degree that pressure is building within the delivery system relative to how much the button/pedal is being depressed. The activating of the sensory signal generator is adapted to provide an indication to the care giver that the anesthetic fluid is flowing without diverting attention of the care giver from the patient.
Further provided is a sonogram detector 46. The sonogram detector is positionable against the patient in proximity to a location where the needle is inserted into the patient. The sonogram detector has an associated television monitor 48. The associated television monitor provides viewing by the care provider and others.
Provided last is a source of electrical potential 52. In this manner the pump, the electrical assembly, the haptic feedback device and sonogram detector are powered.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
