Benefits of technology

[0010]It is an object of the present invention to at least partly overcome one or more of the above identified limitations of prior art. Specifically it is an object to provide an improved dialysis device securing that a treatment objective is reached while allowing flexibility in the individual treatment sessions. This may be achieved by means of a dialysis device comprising a prescriber interface and a programming means configured to allow, via the prescriber interface, input of a set of therapeutic objectives and a treatment plan and a re-evaluation means configured to, as a function of the therapeutic objectives and the treatment plan, suggest at least one treatment option comprising a set of settings of a treatment session to achieve said set of therapeutic objectives.

Problems solved by technology

However, the devices provided with a patient interface, such as are described in the prior art, are not programmed in such a way as to define therapeutic or clinical objectives to be achieved, for example a predefined creatinine clearance value, a given dose defined as a Kt / V ratio where K=clearance of urea (ml / min), t=time on dialysis (min), V=volume of urea distribution in the body (ml), an individualized water removal target, a sodium balance.
Moreover, if treatment settings are modified by the patient, the devices of the prior art are limited to verifying the desired modification.

example i

[0083]Patient B according to the above exemplified treatment plan, may want to shorten the duration of the treatment session from 5 to 4 hours on a particular day. If this new duration of treatment is within the set limits the modification is allowed.

[0084]Based on a modified setting the re-evaluation means determines how other treatment settings may be changed to achieve the therapeutic objectives and suggests at least one treatment option. The re-evaluation means may also take into account other available data of the patient such as the treatment history and current treatment parameters when suggesting new treatment options to achieve the therapeutic objectives.

example ii

[0085]Patient A according to the above exemplified treatment plan, has gained 3.0 kg since the last treatment session, a weight which has to be taken off to reach the therapeutic objective of the dry weight. The maximum allowed weight loss rate may have been set to 800 g / hour, in which case the maximum total weight loss that may be achieved in the prescribed 2.5 hour treatment is 2.0 kg. The re-evaluation means suggests a treatment option where the duration of the treatment is prolonged to 3 hours and 45 minutes, which allows the dry weight to be reached while maintaining a safe weight removal rate. The re-evaluation means may suggest a second treatment option, where a weight loss of only 2.0 kg in the current treatment session is reached, leaving a “debt” until the next treatment session.

example iii

[0086]During a treatment of Patient B, the maximum blood flow that may be achieved is 300 ml / min due to that the needles have been somewhat misplaced during cannulation. This is lower than the blood flow of 350 ml / min according to the entered treatment plan. Thus, the treatment dose (spKt / V=1.2) will not be reached as planned. The re-evaluation means suggests a treatment option showing an increase of the dialysis fluid flow rate from 500 to 800 ml / min. If increase of dialysis fluid flow is not sufficient to reach the treatment dose objective, additionally the re-evaluation means will suggest a treatment option where the treatment time is extended. Alternatively, the re-evaluation means may suggest a treatment option resulting in that a dose “debt” is left for the next treatment session or treatment sessions.

[0087]As exemplified above, there may be one or several options for the patient to choose from to reach the therapeutic objective.

Abstract

A dialysis device comprising a prescriber interface and a programming means configured to allow, via the prescriber interface, input of a set of therapeutic objectives and a treatment plan and a re-evaluation means configured to, as a function of the therapeutic objectives and the treatment plan, suggest at least one treatment option comprising a set of settings of a treatment session to achieve said set of therapeutic objectives.

Description

FIELD OF THE INVENTION[0001]The present invention concerns the field of dialysis treatment. It relates more particularly to a dialysis device comprising an automated peritoneal dialysis machine or a hemodialysis machine that, based on input of certain data, is programmed to carry out a treatment session.BACKGROUND OF THE INVENTION[0002]Treatment of a patient with renal insufficiency is typically carried out according to a treatment plan created by a prescriber, such as a physician, based on certain therapeutic objectives. The treatment plan may comprise a schedule of treatment sessions and specific settings for each scheduled treatment session. The treatment plan typically also includes dietary advice, medications, frequency of blood samples for follow-up etc.[0003]Treatment of renal insufficiency typically takes place in individual treatment sessions. One session may have duration between 1 and 12 hours.[0004]Certain conditions may effect the actual execution of the treatment plan ...
