Definitions

  • the present invention relates to a method for calibrating an anti-decubitus mattress and to a device capable of performing such method.
  • Anti-decubitus mattresses are known in the art for preventing ulcers, bedsores and the likes in bedridden people.
  • the general approach of known anti-decubitus mattresses is to provide a plurality of cells connected to each to form a mattress and to inflate/deflate the cells in an interleaved manner, so as to improve blood circulation and in order to avoid a prolonged contact of the same body parts with the mattress.
  • FIG 1A schematically illustrates a side view of an anti-decubitus mattress known from the prior art
  • figure 1B schematically illustrates a top view of the same anti-decubitus mattress.
  • the anti-decubitus mattress 1000 has a plurality of cells 1100, 1200, connected in an interleaved manner.
  • an anti-decubitus operation can be obtained.
  • cells 1100 can be partially deflated while cells 1200 are kept inflated.
  • cells 1200 can be inflated again while cells 1100 are partially deflated, and so on.
  • the alternance of the body support by means of cells 1100, 1200 provides the anti-decubitus functionality.
  • anti-decubitus mattress 1000 can be changed, as long as an interleaved operation of the cells achieves movement of the body.
  • An alternative example of a possible arrangement of the cells is illustrated in the anti-decubitus mattress 2000 of figure 2 .
  • the operation of anti-decubitus mattress 2000 is similar to that of anti-decubitus mattress 1000.
  • the cells of anti-decubitus mattress 1000 are alternatively inflated/deflated over time. This allows the user of the anti-decubitus mattress 1000 the possibility to choose the pressure values of the cells 1100, 1200. In particular, it is advantageous to adapt the inflating pressures to the user of the anti-decubitus mattress 1000. Generally speaking, lower pressure values are generally preferred for lighter users while higher pressure values are generally preferred for heavier users.
  • One approach consists in placing a sensing mat under the anti-decubitus mattress.
  • the sensing mat is provided with a deformable rubber pipe having its input connect to the none connecting the input of the anti-decubitus mattress and the output of an air compressor inflating the anti-decubitus mattress.
  • the output of the rubber pipe is free.
  • the maximum pressure which can be used to inflate the anti-decubitus mattress is the pressure at which the deformable rubber pipe opens, thus leading the air outside. In this manner, a heavier user placed on the anti-decubitus mattress will exert more pressure on the anti-decubitus mattress and, in turn, on the deformable rubber pipe of the sensing mat, thus closing it, until a pressure high enough to open it again is achieved.
  • This system has a number of disadvantages.
  • the deformable rubber pipe risks remaining blocked due to the bent in the sensing mat, thus unnecessarily increasing the inflating pressure of the anti-decubitus mattress.
  • An alternative known approach consists in inflating all cells 1100, 1200, to a predetermined pressure and then opening, for a predetermined time, an output valve of the anti-decubitus mattress. Once the output valve is closed, the pressure in the anti-decubitus mattress is measured. The pressure difference resulting from the air flowing out of the output valve is a function of the weight that was placed on the anti-decubitus mattress. Thus, by measuring the pressure difference, the weight of the user can be computed and the pressure of the anti-decubitus mattress can be set accordingly.
  • One important disadvantage is the need for a precision outflow of air.
  • the time of the outflow is easily controllable, however the output valve characteristics are more complex to maintain stable.
  • the output valve needs to be precisely manufactured so as to ensure that each output valve has the same outflow characteristics.
  • the output valve may become partially obstructed during time, for instance by external objects such as bed linens, or by dirt in the compressed air. Even a partial obstruction has the result that the outflow characteristics of the output valve change, thus invalidating the computational assumptions which are used to derive the weight of the user from the measured pressure difference.
  • the pressure variation that is the difference between initial pressure and pressure after the outflow, is not only a function of the weight placed on the anti-decubitus mattress but also on the initial pressure. This requires the system to be capable of setting a known and stable value of the initial pressure, which increases the complexity of the system.
  • the deflation of cells 1100 also implies that the user has to lie only on cells 1200 for some time, which may be uncomfortable or painful. In some cases, the lack of support from deflated cells 1100 may thus not be acceptable.
  • the body parts which are placed over deflated cells 1100 may get in contact with the bed's surface. This reduced the weight which is supported by the inflated cells 1200 and thus results in an incorrect computation of the user's weight.
  • Anti-decubitus mattresses according to the prior art are known, for instance, from documents WO 2015/132560 A1 and US 2005/0091752 A1 .
  • the invention is based on the general concept that the weight of the user can be computed by a pressure measurement.
  • the pressure measurement can be done on some of the cells of the mattress after some other cells have been inflated more, so as to support more of the body of the user.
  • 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 second pressure value can be comprised between 15 and 50 Torr, more preferably between 25 and 35 Torr.
  • a difference between the second pressure value and the first pressure value can be comprised between 5 and 35 Torr, more preferably between 10 and 20 Torr.
  • the first cells and the second cells are inflated at a first pressure value.
  • the calibrating step comprises computing a weight value based on the third pressure value.
  • the weight value is computed based on a look-up table.
  • a further embodiment of the invention relates to a device for calibrating an anti-decubitus mattress, the anti-decubitus mattress comprising a plurality of first cells and a plurality of second cells, the device comprising: a first pipe for pneumatically connecting to the first cells, a second pipe for pneumatically connecting to the second cells, a first valve pneumatically connected to the first pipe, a second valve pneumatically connected to the second pipe, a compressor pneumatically connected to the first valve and to the second valve, and a controller configured to control the first valve, the second valve and the compressor.
  • the device can further comprise a pressure sensor connected to the second pipe, wherein the controller can further be configured to be connected to the pressure sensor.
  • the anti-decubitus mattress can further comprise a pressure sensor pneumatically connected to the second cells, wherein the controller can further be configured to be connected to the pressure sensor.
  • 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 S3300, 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 method 3000 comprises an inflating step S3400, in which the first cells 1100 are inflated at a second pressure value P2.
  • the second pressure value is preferably higher than the first pressure value P1.
  • the second pressure value P2 is preferably higher than the pressure value at which the other cells, namely those which are not inflated, are inflated.
  • This inflating step results in the configuration schematically illustrated in figure 4B .
  • the increased pressure in the first cells 1100 results in those cells supporting more weight than the non-inflated cells and, in particular, supporting more weight than second cells 1200.
  • This results in less weight being supported by the second cells 1200 and thus in a reduction of the value of the pressure within second cells 1200 to a third pressure value P3.
  • the pressure value P3 is a function, among others, of the weight of the user lying on the anti-decubitus mattress.
  • 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.
  • the method 3000 is particularly advantageous in view of the prior art.
  • the first pressure value P1 is preferably comprised between 5 and 30 Torr, more preferably between 10 and 22 Torrs. Those values ensure a safe and reliable operation of the method 3000, in particular since they avoid the weight of the user to rest on the structure underneath the anti-decubitus mattress.
  • the second pressure value P2 is preferably comprised between 15 and 50 Torr, more preferably between 25 and 35 Torr. Those values ensure a safe and reliable operation of the method 3000, in particular by avoiding overinflating the cells, which would result in the user being supported entirely by the first cells 1100, causing pain and/or medical issues.
  • 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.
  • the calibrating step S3600 can further comprise setting an inflating pressure of the anti-decubitus mattress at a fourth pressure value P4 and setting a deflating pressure of the anti-decubitus mattress at a fifth pressure value P5, based on the outputted weight W1.
  • weight W1 and the pressure values P4 and P5 can be obtained in several known manners, for instance based on a look up table.
  • an exemplary look-up table is here reported for clarification: Weight W1 (Kg) Inflating pressure P4 (Torr) Deflating pressure (Torr) P5 0 20 5 50 22 5 100 26 5 150 32 8

  • the look-up table is populated, at a populating step S325, by assigning the current value of the inflating pressure of the cells 1100, 1200 to the fourth pressure value P4. If, on the other hand, the measured contact pressure falls outside of the range, the pressure at which the cells are inflated is changed, at a step S3240, and the steps S3220 and S3230 are repeated.
  • step S3200 can be carried out repeatedly, with different values of weight W1, so as to populate a look-up table associating different values of W1 to different values of P4.
