Definitions

  • This invention relates to an alternating pressure mattress for preventing pressure ulcers, particularly around the heel region of a patient's limb.
  • Bed sores, or pressure ulcers are likely to occur when a patient is bed ridden for a long period of time, causing parts of the body that are in contact with the mattress to be constantly subjected to pressure. This results in obstructed blood flow, which can damage the affected tissue and ultimately leads to bed sores.
  • the reduced blood flow is especially severe in areas of skin near a protruding bone such as the heel or the hip, and accordingly bed sores are more likely to develop at these locations.
  • the unobstructed blood supply to the heel is relatively poor compared to the rest of the body. The heel is therefore especially prone to bed sores.
  • bedsores on the heel and similar areas are slow to heal.
  • the tissue that was supported by the deflated cells is provided with pressure relief.
  • the degree of pressure relief provided depends on the extent to which the cells are deflated.
  • a mattress may be provided in which the cells simply have a valve opened to allow the pressure therein to gradually reduce towards atmospheric pressure. In this event the pressure will not actually reach atmospheric pressure because the open valve still provides a resistance to the air escaping, so air is only removed by the pressure caused by the patient's weight, which is largely supported by the inflated cells once the pressure in the deflated cells has reduced. Therefore, there is a small residual pressure between the patient and the deflated cells.
  • a mattress For patients who face a higher risk of developing a bed sore a mattress may be provided which actively pumps the air out of the deflated cells, ensuring that no residual pressure is applied by the deflated cells. Completely evacuating the air out of the cells makes the mattress more effective in preventing bed sores.
  • active pumping a small valve can be used so that initial evacuation is not sudden but, by virtue of the pump, the rate of evacuation remains substantially the same so that complete evacuation does occur, over a relatively short period of time, without the initial sudden rush that would otherwise potentially disturb a patient sleeping on the mattress.
  • the present invention aims to provide a low-cost mattress that provides complete pressure relief to areas of tissue that face a particularly high risk of developing a bed sore.
  • an alternating pressure mattress system comprising a first compressor and a mattress having a plurality of cells lying transversely with respect to a length of the mattress and disposed in side by side relationship along the length of the mattress between first and second ends thereof, the cells divided into at least four groups of cells, a first and second of said groups of cells being located in a first section of the mattress and a third and fourth of said groups of cells being located in a second section of the mattress, which groups of cells are arranged to be cyclically inflated and deflated, wherein:
  • the air in the cells in said first and second groups of cells is actively evacuated when said cells are deflated;
  • the air in the cells in said third and fourth groups of cells is allowed to vent to atmosphere when said cells are deflated, no active evacuation being provided;
  • said active evacuation comprises pumping the air out of the cells using a second compressor.
  • said second compressor may be the same as said first compressor.
  • the mattress may further comprise longitudinal edge cells extending along longitudinal edges of the mattress.
  • said first section of said mattress may be located at said first end of said mattress, whereby an average patient on the mattress may be provided with periodic total pressure relief of their heel region when lying on said first end of said mattress.
  • the mattress may further comprise at least one additional cell near said second end of the mattress that is configured to remain inflated throughout said predetermined cycle, whereby a patient on the mattress may be provided with constant support of their head when lying on said at least one additional cell.
  • system may further comprise a quick release mechanism configured to permit rapid deflation of all of the cells.
  • the quick release mechanism may be configured to fully deflate the cells within 30 seconds of being activated, preferably within 15 seconds of being activated.
  • the cells may be divided into two groups which are cyclically inflated and deflated.
  • the invention relates to a mattress for a system as described above, the mattress comprising said plurality of groups of cells, wherein the cells of each group comprise connections and tubing associated with said connections which are separate from the connections and tubing associated with said connections of the cells of the other groups.
  • a different embodiment of the invention relates to a method for the prevention or treatment of bed sores in a patient, said method comprising the steps of:
  • a mattress having a plurality of cells divided into at least two groups of cells which may be inflated or deflated;
  • the cells in a first section of the mattress located near said first end of the mattress are actively evacuated when said cells are deflated, said first section including cells from each of said two groups of cells; the cells in a second section of the mattress are vented to atmosphere when said cells are deflated, no active evacuation being provided, said second section including cells from each of said two groups of cells; and
  • said active evacuation comprises pumping the air out of the cells using a compressor.
  • a different embodiment of the invention relates to a pump unit for an alternating pressure mattress comprising:
  • valves configured to control the flow of air to and from said first and second compressors and said first, second, third and fourth connectors; and a control unit configured to control said valves and said compressor,
  • control unit is configured to control said valves and said compressors to cyclically inflate and deflate mattress cells attached to said connectors;
  • said cells attached to said first and second connectors are arranged to be deflated by active evacuation of the air from said cells using said second compressor; and said cells attached to said third and fourth connectors are arranged to be deflated by allowance of the air in the cells to vent to atmosphere, no active evacuation being arranged.
  • said second compressor may be the same as said first compressor.
  • control unit may be configured to cyclically: deflate mattress cells attached to said first and third connectors; inflate mattress cells attached to said first and third connectors; deflate mattress cells attached to said second and fourth connectors; and inflate mattress cells attached to said second and fourth connectors.
  • the pump unit may further comprise a fifth connector, wherein said control unit is configured to maintain cells attached to said fifth connector constantly inflated whilst cyclically inflating and deflating the cells attached to said first, second, third and fourth connectors.
  • the pump unit may further comprise a pressure sensor disposed between said first or second compressor and said connectors.
  • Figure 1 is a prior art alternating pressure mattress for preventing bed sores
  • Figure 2 shows a graph of the pressure within a cell against time for different methods of deflation
  • Figure 3 shows a cross section of an alternating pressure mattress for preventing bed sores in an embodiment of the present invention
  • Figure 4 shows an exemplary air circuit diagram for an alternating pressure mattress in an embodiment of the present invention.
  • Figure 5 shows a pump unit in an embodiment of the present invention.
  • Figure 1 shows a prior art alternating pressure mattress configured to prevent or treat pressure ulcers by cyclically reducing the pressure applied to different areas of the body of a patient sleeping on the mattress.
  • the mattress comprises a plurality of inflatable cells arranged perpendicular to the longitudinal axis A of the mattress (only eight being shown).
  • the cells are divided into at least two groups of alternately disposed cells, which groups of cells are configured to be cyclically inflated and deflated in a predetermined cycle that ensures that at least one group of cells is inflated at any given time on which the patient is supported.
  • a typical mattress between 16 and 24 cells will be provided, and the cells will be deflated using either a "two cell cycle” or a "three cell cycle", which means that there are two or three groups respectively of cells. If a two cell cycle is used then the cells may be divided into two groups, with adjacent cells in different groups. Alternatively, a "three cell cycle” may be used, and in that case the cells are divided into three groups, for example a first group comprising cells 2i , 2 4 and 2 7 , a second group comprising cells 22, 2 ⁇ and 2s and a third group comprising 23 and 2Q. In either case the groups of cells are cyclically inflated and deflated in a cycle that ensures that at least one group of cells is inflated at any given time.
  • prior art mattresses also include at least one compressor for inflating the cells and a controller for selecting which cells are to be inflated or deflated.
  • the controller may be configured to open valves to deflate selected cells at predetermined time intervals, and to actuate the pump and direct the airflow to selected cells to inflate them at predetermined time intervals.
  • the cells 2 in Figure 1 have a generally circular cross section. This is typically the case for mattresses in which the cells are vented to atmosphere as illustrated by pressure profile 5 when they are deflated. These mattresses represent the lowest cost type of mattress. However, for mattresses in which the air is actively pumped out of the cells as illustrated by pressure profile 6 it is generally necessary to elongate the cells so that they have a generally elliptical cross section, with the major axis of the ellipse arranged so that it is vertical when the mattress is in use. If the air was actively evacuated from a mattress having cells with a generally circular cross section then it is probable that the patient would come into contact with the bottom surface of the mattress between inflated cells.
  • the mattress shown in Figure 1 also includes longitudinally oriented side support cells 3, which help to prevent the patient from accidentally rolling off the mattress. Such side support cells remain continuously inflated when the mattress is in use.
  • Figure 3 shows a cross section of an alternating pressure mattress in an embodiment of the present invention.
  • the mattress has cells inflated and deflated in a 2 cell cycle and the structure of the mattress is similar to that shown in Figure 1.
  • Figure 3 shows cells 2'2 and 2 deflated to approximately zero pressure, whist cells 2Q, 2S, 2IO and 2i2 all retain some residual pressure.
  • the group of cells that is deflated in Figure 3 will be inflated and the group of cells comprising cells 2 ⁇ , 2'3, 2 ⁇ , 2 7 , 2g, 2i i and 2 will be deflated.
  • a patient may be disposed on the mattress with their heels located at the first end. In this way the complete deflation of the cells near a first end of the mattress (i.e. cells 2 ⁇ , 2'2, 2'z and 2 ) advantageously provides total pressure relief to the heel of a patient sleeping on the mattress.
  • cells 2s to 2 are not completely deflated, they provide some residual support to a patient who is unlikely to contact the under surface. Nevertheless, they still benefit from changing pressure on their body so that the risks of bed sores and pressure ulcers developing, in these less-susceptible regions of the body, are still substantially mitigated.
  • the timing and phasing of the inflation and deflation of the cells at the first end of the mattress may be different from the timing and phasing of the inflation and deflation of the other cells (i.e. cells 2s-2i3).
  • Some cells at a second end of the mattress may be in an additional group that remains constantly inflated when the mattress is in use, thereby providing constant support to the patient's head.
  • FIG. 4 shows an exemplary air circuit diagram for an alternating pressure mattress configured to implement a 2 cell cycle in an embodiment of the present invention.
  • Air circuit 10 connects groups of cells A, A', B, B' and C to compressor 1 1 via filter/sliencer 12, air pipes or tubing 14 and valves 15.
  • the valves 15 and compressor 1 1 are controlled by a control unit (not shown), which is in communication with pressure sensor 13.
  • Filter/silencer 12 is provided to damp away any high-frequency pulsations that are introduced by compressor 1 1 that might otherwise cause the patient discomfort.
  • Groups of cells A' and B' are disposed at a first end of the mattress where the heels of a patient are likely to rest.
  • Group of cells C is disposed at a second end of the mattress opposite said first end and is configured to be continuously inflated when the mattress is in use.
  • Groups of cells A and B are disposed between said first and second ends.
  • Groups of cells A' and B' may each comprise between one and three cells, preferably two cells, and group of cells C may comprise between 1 and 6 cells, for example 4 cells. The remainder of the cells are in group of cells A or B. Cells preferably alternate between group of cells A (or A') and group of cells B (or B') along the length of the mattress.
  • group of cells A' may comprise cells 2 ⁇ and 2'3
  • group of cells B' may comprise cells 2'2 and 2' 4
  • group of cells A may comprise cells 2s, 2 7 , 2g, 2n and 2i3
  • group of cells B may comprise cells 2Q, 2S, 2io and 2i2.
  • Group of cells C is not shown in Figure 3. Not all cells A, B, A' or B' are shown in the drawings. Typically, there are sixteen to thirty cells forming a mattress, with each cell being between 5 and 15 cm, preferably about 10 cm, in diameter. Furthermore, the cells disposed at the first end of the mattress (i.e. the cells in groups A' and B') may be of a different size to rest of the cells (i.e. the cells in groups A, B and C).
  • Valves 15 are controlled by the control unit to connect or disconnect cells from different air tubes.
  • valve 153 is configured to selectively connect group of cells A' either to air pipe 14, which communicates with the outlet of compressor 1 1 , or air pipe 14', which communicates with the inlet of compressor 1 1 , via valve 15i .

  • the controller may first inflate all of the cells to a predetermined pressure.

  • compressor 1 1 is stopped.
  • a predetermined time delay either groups of cells A' and A, or B' and B, are deflated.
  • Group of cells A or B is deflated by actuating one of valves 15s or 15e and connecting the group of cells to air pipe 14", which vents to atmospheric pressure. In this event, these cells deflate gradually so as to minimise disturbance of a patient whose body is supported by them, possibly asleep.
  • group of cells A' or B' is deflated by actuating one of valves 153 or 15 4 , thereby connecting the group of cells to air pipe 14', which communicates with the inlet of compressor 1 1 via valve 15i .
