ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to dialysis machines and more particularly pertains to a new portable kidney dialysis system for automatically conducting kidney dialysis with a belt mounted unit.
2. Description of the Prior Art
The use of dialysis machines is known in the prior art. More specifically, dialysis machines heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art dialysis machines include U. S. Pat. No. 4,765,907; U.S. Pat. No. 5,425,719; U.S. Pat. No. 4,443,333; U.S. Pat. No. 4,180,460; U.S. Pat. Des. No. 308,249; and U.S. Pat. No. 3,955,867.
In these respects, the portable kidney dialysis system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of automatically conducting kidney dialysis with a belt mounted unit.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of dialysis machines now present in the prior art, the present invention provides a new portable kidney dialysis system construction wherein the same can be utilized for automatically conducting kidney dialysis with a belt mounted unit.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new portable kidney dialysis system apparatus and method which has many of the advantages of the dialysis machines mentioned heretofore and many novel features that result in a new portable kidney dialysis system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art dialysis machines, either alone or in any combination thereof.
To attain this, the present invention generally comprises a belt with an adjustable length. The belt includes a pair of free ends having a male and female couples attached thereto, respectively. The couples serve for securing the belt on a user.
FIGS. 1 & 3
show a drain bag pocket mounted on an outer surface of the belt. The drain bag pocket extends along ¾ of a length of the belt at a rear extent thereof. The drain bag pocket includes a lid integrally coupled to a top edge of the belt with a pile fastener mounted thereon. The pile fastener is adapted for releasably coupling with a pile fastener mounted on a front face of the drain pocket along an entire length thereof. Next provided is a drain bag having a length equal to ¾ that of the belt and a width equal to that of the belt. The drain bag has an end with a flexible tube coupled thereto and extending therefrom. As shown in
FIG. 4
, the flexible tube terminates with a couple including a rigid tube with a pair of gripping ears extending radially therefrom. Further extending from the couple is a pair of diametrically opposed coupling protrusions. Mounted on an outer surface of the belt adjacent to an end of the drain bag pocket is a pump. A first flexible tube is coupled to the pump and extends within a body of a user. Also coupled to the pump is a second flexible tube terminating with a couple. The couple of the second flexible tube includes a rigid tube with a pair of gripping ears extending radially therefrom and a pair of diametrically opposed coupling slots formed in an inner surface thereof. As such, the present couple is adapted for coupling with the couple of the drain bag and that of a fill bag which is filled with fluid. In use, the pump is adapted to pump fluid from the first flexible tube to the second flexible tube only upon the receipt of a drain signal. Further, the pump serves to pump fluid from the second flexible tube to the first flexible tube only upon the receipt of a fill signal. Mounted within the second flexible tube is a pressure sensor for providing a full signal only upon the detection of a pressure exceeding a predetermined amount. Associated therewith is a flow sensor which is also mounted within the second flexible tube. The flow sensor is adapted for providing a flow signal only upon the detection of a flow of fluid. As shown in
FIG. 5
, an audio means is included for generating an audible signal only upon the actuation thereof. Finally, control means is mounted on the outer surface of the belt and connected between the pump, the pressure sensor, the flow sensor, audio means, a timer and a manual switch. In use, the control means has a first mode for when the drain bag is connected to the second flexible tube of the pump. In such mode, the drain signal is transmitted for a predetermined amount of time to the motor intermittently at predetermined intervals for filling the drain bag with fluid from the body of the user. Upon the receipt of the flow signal, the pump ceases intermittent transmission of the drain signal and continuously transmits the drain signal until the receipt of either the full signal or the lack of receipt of the flow signal. For alerting the user, the control means only actuates the audio means upon receipt of the full signal. When the drain bag is full, the control means further has a second mode for when the second flexible tube of the pump is connected to the fill bag. It should be noted that the control means only operates in the second mode upon the closing of the manual switch by the user via the rotation of the dial shown in FIG.

. In the second mode, the control means is adapted for transmitting the fill signal to the pump thereby inserting fluid from the fill bag within the body of the user.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new portable kidney dialysis system apparatus and method which has many of the advantages of the dialysis machines mentioned heretofore and many novel features that result in a new portable kidney dialysis system which is not anticipated, rendered obvious, suggested, or even implied by any of
