DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention concerns a method for the management of parameters relating to a dialysis treatment and a dialysis machine capable of implementing such a method.
2. Description of the Related Art
The method and the dialysis machine referred to are particularly, but not exclusively, well suited for dialysis treatments at home where generally no provision is made for using a specialist (doctor or nurse) on a continuous basis for supervising the progress of the treatment session.
It is obvious, at least in theory, that a dialysis machine may be operated on a remote control and continuous basis by means of a receiver device disposed in a centralized control station, by connecting this receiver device to the dialysis machine, for example, through a telephone line.
It has been found that the continuous control of the dialysis machine requires the transfer and storage of an enormous quantity of values over a relatively long period on the order of three to four hours, corresponding to the whole treatment period. The consecutive utilization of the values obtained entails a considerable loss of time, both for the machine and the receiver device, because many values are controlled which probably have not changed over the whole treatment period. The above outline shows the need for making a method available for the management of the parameters relating to a dialysis treatment, which permits a successive transfer and utilization of numerical data in a much shorter time than at present, so as to make it possible to use in a control station a relatively simple and moderately powered operating unit and which is therefore relatively inexpensive.
SUMMARY OF THE INVENTION
An object of the present invention is therefore to propose a method and a dialysis machine which allow the requirements set out above to be met.
This object is achieved by the present invention which concerns a method for the management of parameters relating to a dialysis treatment including functioning of the said dialysis machine in relation to the progress of the treatment with respect to time and/or to the course of the values of the said parameters in relation to predetermined variation ranges of these parameters; said parameters in accordance with the establishment of each one of the operating conditions. According to one characteristic of the invention, the method comprises a preliminary operation which lies in choosing from the said selected parameters, the said number of parameters to be kept in the memory.
According to another characteristic of the invention, the operations (b) of establishing a plurality of the functional operating conditions and (c) of memorizing the values assumed by the said parameters lie, in essence, in:
defining, at least for some of the selected parameters, ranges of variations (delimited by respective threshold limits) of their respective values which they may assume during the said treatment;
verifying any possible excesses of the above mentioned threshold limits;
memorizing for each excess of at least one threshold limit by the corresponding parameter, the value assumed at that moment by at least that parameter, this memorizing operation being effected, for example, either whenever the value assumed by at least one of the said parameters deviates from a range of admissible values, or whenever the value of a parameter having deviated from the said range of admissible values reenters the said range.
According to another characteristic of the invention, the operations for establishing a plurality of functional operating conditions and for memorizing the values assumed by the said parameters lie, in essence, in establishing a periodicity for the memorization of the values of the said parameters, and in automatically effecting the said memorization of the values of the said parameters according to the said periodicity.
The present invention relates, moreover, to a dialysis machine characterized in that it comprises:
a) means for selecting a plurality of paramet
