Method and device for determining a position at which to deliver a substance
A method for determining a position or location for delivering a substance including providing at least one piece of reference information or a reference point, determining a location for the delivery based on the piece of reference information or in relation to the provided reference point, and outputting the determined location. The invention encompasses a device for use in the method, the device including a memory which stores reference data or patient-specific data, a computer which determines a position based on the data stored in the memory, and an output unit which outputs the determined position.
1 . A method for determining a site at which an infusion of a substance can take place, said method comprising the steps of:
predefining at least one of one item of reference information or a reference site,
determining the site based on said reference information or relative to the reference site, and
outputting the determined site.
2 . The method as claimed in claim 1 , wherein the site is determined using an algorithm that employs at least one of predefined body-specific data, predefined infusion-specific data, infusion position patterns and data recorded during an infusion.
3 . The method as claimed in claim 2 , wherein the locations of previously used infusion sites are recorded and employed by the algorithm.
4 . The method as claimed in claim 2 , further comprising employing data relating to the type of infusion set used.
5 . The method as claimed in claim 2 , further comprising employing information relating to the type of substance to be infused.
6 . The method as claimed in claim 2 , further comprising using an image of one or more infusion areas to determine or to represent the location of a determined site.
7 . The method as claimed in claim 2 , wherein a predefined infusion area is divided into zones.
8 . The method as claimed in claim 7 , wherein in the predefined infusion area regions are defined in which no infusion is to be carried out.
9 . The method as claimed in claim 6 , wherein a representation of a recorded infusion area can be at least one of enlarged and mirrored.
10 . The method as claimed in claim 9 , wherein a printout with one of more of the determined sites and the recorded infusion areas is created.
11 . The method as claimed in claim 2 , wherein the time during which an infusion is carried out at a site is recorded.
12 . The method as claimed in claim 1 , further comprising determining a new site after a predefined or determined period of time.
13 . The method as claimed in claim 1 , in which the efficacy of the infused substance is measured and used in the determination of a new site.
14 . The method as claimed in claim 1 , in which patient-specific parameters are used in determining the site.
15 . The method as claimed in claim 1 , wherein the method is used on different users.
16 . A computer program which, when loaded in a computer or running on a computer, executes a method comprising the steps of predefining at least one of one item of reference information or a reference site, determining the site based on said reference information or relative to the reference site, and outputting the determined site.
17 . A program storage medium or computer program product with the computer program as defined in claim 16 .
18 . A device for determining a position to carry out a substance discharge, said device comprising a memory for storing items of reference information or patient-specific parameters, a computing unit for determining the position based on the data stored in the memory unit, and an output unit that outputs the determined position.
19 . The device as claimed in claim 18 , further comprising an input unit for input of patient-specific or therapy-specific parameters.
20 . The device as claimed in claim 18 , further comprising a camera or a scanner for recording at least one injection area.
21 . The device as claimed in claim 18 , further comprising a time-recording device.
22 . The device as claimed in claim 18 , further comprising a sensor for measuring the efficacy of the discharged substance.
23 . The device as claimed in claim 18 , further comprising a display device for displaying the determined position.
24 . The device as claimed in claim 18 , further comprising a printer for printing out an infusion schedule.
25 . The device as claimed in claim 24 , wherein said printing is done on a transparent film.
26 . A system comprising an infusion device and a device for determining a position to carry out an infusion, said device for determining comprising a memory for storing items of reference information or patient-specific parameters, a computing unit for determining the position based on the data stored in the memory unit, and an output unit that outputs the determined position.
