Definitions

  • an embodiment of the invention can relate to a method for calibrating an anti-decubitus mattress, the anti-decubitus mattress comprising a plurality of first cells and a plurality of second cells, the method comprising the steps of: inflating the first cells at a second pressure value, measuring a third pressure value of the second cells, calibrating the anti-decubitus mattress based on the third pressure value.
  • the first cells and the second cells can be inflated at a first pressure value.
  • the weight value can be computed based on a look-up table.
  • Figure 3A schematically illustrates a method 3000 for calibrating an anti-decubitus mattress according to an embodiment of the invention.
  • the method 3000 comprises an inflating step S3400, in which the first cells 1100 and the second cells 1200 are inflated at a first pressure value P1.
  • This situation is schematically illustrated in figure 4A , in which the first pressure value P1 is indicated next to the pipes 4110 and 4210.
  • the pressure value P3 is a function, among others, of the weight of the user lying on the anti-decubitus mattress. Thus, by measuring the pressure value P3 it is possible to deduct the weight and thus calibrate the anti-decubitus mattress accordingly.
  • the method 3000 therefore further comprises a measuring step S3500, in which the third pressure value P3 of the second cells 1200 is measured. Thereafter, a calibrating step S3600 is carried out for calibrating the anti-decubitus mattress 1000 based on the third pressure value P3.
  • a difference between the second pressure value P2 and the first pressure value P1 is preferably comprised between 5 and 35 Torr, more preferably between 10 and 20 Torr.
  • Those values ensure a safe and reliable operation of the method 3000, in particular by ensuring a sufficient different in pressure between the first cells 1100 and the second cells 1200, so as to allow the weight to be partially shifted to the first cells 1100 thus enabling a pressure reduction in the first cells and its reliable measurement.
  • the calibrating step S3600 comprises computing a weight value of the person lying on the anti-decubitus mattress based on the third pressure value P3.
  • the weight value W1 can be computed based on a look-up table.
  • the following presents an example of the look-up table based on an exemplary P1 value of 15 Torr and an exemplary P2 value of 30 Torr: P1 (Torr) P2 (Torr) P3 (Torr) Weight W1 (Kg) 15 30 15 0 15 30 14 50 15 30 12 100 15 30 10 150
  • the calibrating step S3600 can comprise inputting the third pressure value P3 into a look-up table and outputting a corresponding value of the weight W1 of the anti-decubitus mattress.
  • the look-up table can be populated by a setting step S3100, which can be preferably carried out prior to the inflating step S3200.
  • the setting step S3100 generally allows populating of the look-up table and it will be clear to those skilled in the art that several manners can be implemented for obtaining a correspondence between the third pressure value P3 and the weight W1. For the purpose of explanation, in the following, a possible embodiment of the setting step S3100 will be described.
  • Figure 3B schematically illustrates a setting step S3100 for populating a look-up table according to an embodiment of the invention.
  • the setting step S3100 can preferably take place prior to the inflating step S3300.
  • the setting step S3100 can comprise a step S3110 of inflating the first and second cells 1100, 1200 at a first pressure value P1, in a manner similar to step S3300.
  • the inflating step S3110 can be carried out, with a person, a mannequin, or a similarly elongated object, having a known weight value W1 lying on the anti-decubitus mattress.
  • the setting step S3100 can further comprise an inflating step S3120, in which the first cells 1100 are inflated at a second pressure value P2, in a manner similar to step S3400.
  • the inflating step S3120 can be carried out, with the person, the mannequin, or the similarly elongated object, having a known weight value W1 lying on the anti-decubitus mattress.
  • the setting step S3100 can further comprise, a step S3130 of measuring a third pressure value P3 in the second cells 1200, in a manner similar to step S3500. Moreover, the setting step S3100 can further comprise a step S3140 of populating the look-up table by assigning, in the look-up table, the known value of W1 to the measured value of P3.
  • the setting step S3100 thus advantageously allows creating different look-up tables for different configurations of the anti-decubitus mattress. That is, different anti-decubitus mattress made with different materials and/or different dimensions, and/or different number of cells can generate a third pressure value P3 different from each other, even though the first and second pressure values P1, P2 as well as the weight W1 are the same.
  • the setting step S3100 described above advantageously allows generating an ad-hoc look-up table for any given configuration of the anti-decubitus mattress.
  • the setting step S3100 only needs to be carried out once for a given kind of anti-decubitus mattress.
  • the resulting values can then be saved in a memory of a device for calibrating the anti-decubitus mattress, such as devices 5000, 6000, where the memory could be implemented by controller 5400, 6400, which will be described later in the description.
  • FIG. 3C schematically illustrates an inflating pressure calibrating step S3200 according to an embodiment of the invention.
  • the inflating pressure calibrating step S3200 can preferably take place prior to the inflating step S3300.
  • the inflating pressure calibrating step S3200 can preferably take place after the setting step S3100.
  • the inflating pressure calibrating step S3200 can comprise a step S3210 of positioning a person, a mannequin, or a similarly elongated object, having a known weight value W1 on the anti-decubitus mattress.
  • the inflating pressure calibrating step S3200 can further comprise a step S3220 of measuring a pressure value which is generated by the weight W1 on the surface of the anti-decubitus mattress on which the weight W1 is positioned.
  • a step S3220 of measuring a pressure value which is generated by the weight W1 on the surface of the anti-decubitus mattress on which the weight W1 is positioned.
  • an average pressure exerted by the weight W1 at the contact points between the weight W1 and the anti-decubitus mattress can be measured.
  • the pressure value can be measured, for instance, through a measuring layer, placed between the weight and the anti-decubitus mattress. Suitable commercial products are available, for instance, from the company Xsensor.
  • the predetermined range can be expressed as a percentage, such as, for instance +/- 20% of the monitored pressure, preferably +/- 10% of the monitored pressure. It will also be clear that, in order to avoid the re-calibration starting for every variation of the pressure, due for instance to a movement, whether the monitored pressure varies outside of the predetermined range can be determined by averaging the monitored pressure over a predetermined time period, such as 10 second or more, preferably 30 seconds or more, even more preferably 60 seconds or more.
  • Figure 5 schematically illustrates a device 5000 for calibrating an anti-decubitus mattress according to an embodiment of the invention. Also in this case, as for the method 3000, reference will be made to the anti-decubitus mattress 1000, for explanation purposes. It will be clear, however, that any anti-decubitus mattress compatible with device 5000 can be used instead.
  • the device 5000 further comprises a first valve 5130 pneumatically connected to the first pipe 5110, and a second valve 5230 pneumatically connected to the second pipe 5210. Also in this case, the valves 5130, 5230 do not need to be directly connected to the pipes 5110, 5210, for instance since other elements can be placed in between. What is sufficient is that valves 5130, 5230 are configured such that they can open and close the access to the pipes 5110, 5210, at least on the side of the device 5000.
  • the device 5000 further comprises a compressor 5300 pneumatically connected to the first valve 5130 and to the second valve 5230. Also in this case, the valves 5130, 5230 do not need to be directly connected to the compressor 5230, for instance since other elements can be placed in between. What is sufficient is that valves 5130, 5230 are configured such that they can open and close the access to the pipes 5110, 5210 with respect to the compressor 5300.
  • the compressor 5300 can be implemented by two compressors, one connected to valve 5130 and one connected to valve 5230.
  • the device 5000 further comprises a pressure sensor 5240 connected to the second pipe 5210.
  • the controller 5400 is preferably also further configured to be connected to the pressure sensor 5240, as illustrated. Thanks to this configuration, it is possible to monitor the pressure value P3 of cells 1200 as previously described.
  • the device 6000 of figure 6 it is possible to use the device 6000 with an anti-decubitus mattress which comprises a pressure sensor 6240 pneumatically connected to the second cells 1200.
  • the controller 6400 can be further configured to be connected to the pressure sensor 6240, for instance via an appropriate plug and/or wireless connection.
  • a pressure sensor can be connected to the first pipe 5110, thus allowing the measurement of the pressure of first cells 1100.
  • any give characteristics of any given embodiment does not need all other characteristics of that given embodiment in order to be implemented. Furthermore any given characteristic of any given embodiment can be combined with any given characteristic of any given embodiment to result in new embodiments.
