Definitions

  • This invention relates to a patient support and in particular to an alternating pressure pad used in prone nursing.
  • Prone nursing is a technique in widespread use, with existing systems requiring the patient to be laid face down onto a bed having specific mechanical lifting aids to lift the patient's chest off the bed to provide a space beneath the face and neck for nasal, ventilation and tracheotomy tubes to be inserted and hang freely from the patient.
  • a nurse With the patient in this position, a nurse has access to the face and neck areas for nasogastric tubes, endogastric tubes, ventilator hoses and tracheotomoy tubing, as appropriate, and can perform medical procedures such as pulmonary drainage via suction.
  • the lifting equipment used has been known in the past to cause facial pressure sores at their points of contact.
  • Alternating pressure pads as shown in WO 95/21599 are commonly used in the prevention of pressure sores in bedridden patients, but such pads do not provide for the nursing of a patient requiring mechanical ventilation or artificial respiration and the nursing of a patient in a prone position. In order to nurse the patient in the prone position the nurse needs to move the patient to a bed with similar lifting equipment as described above, with the attendant risks of pressure sores.
  • the invention seeks to provide an alternating pressure pad capable of supporting a patient in a prone position thereby avoiding the need to move the patient to a different bed and additionally maintaining pressure relief for the patient.
  • the invention provides a pressure pad as defined by claim 1.
  • the deflation of the cells at the head end of the pad provides a space beneath the face and neck of a patient for nasal, ventilation and tracheotomy tubes to be inserted and hang freely.
  • the cell under the pad raises the level of the lungs above the rest of the body and lowers the abdominal tissue pressure thereby reducing pressure on the diaphragm and allowing greater tidal air volume during artificial respiration.
  • there is greater perfusion and oxygenation of the dorsal lower lung area reducing accumulation of oedema around the lung and chest area.
  • At least one inflatable cell is provided under the foot end of the pad to raise the feet of a patient supported on the pad.
  • the cells under the pad may be inflated laterally to provide rotational therapy for the patient.
  • the pad includes at least a further inflatable cell to support the face and shoulder of a person lying thereon.
  • the cell is V-shaped and may be semi-transparent to allow inspection of the face from the side of the pad without movement of the head. The combined action of the deflated head cells, the cells elevating the chest and feet and the V-shaped cell to raise the face and neck provides an optimum position for prone nursing which is difficult to achieve on conventional air beds or pads.
  • the alternately inflatable cells for supporting the abdomen of a patient lying thereon may be individually selectively deflated to facilitate breathing.
  • a cover extends over and around the pad.
  • control means and the means for selectively deflating some of the cells are accessible outside the cover, for ease of operation and reduced risk of contamination of the pad.
  • the preferred embodiment comprises an alternating pressure pad 1 including alternately inflatable cells 1', 1''.
  • the cells 1' and 1'' are alternately supplied with air from a compressor 2.
  • the cells 1' and 1'' are supplied air from respective channels 6 and 7. It is envisaged that cells in series of three or more may also be used or that more than one cell in any one series may be inflated alternately.
  • the cells are shaped as elongate cylinders which in the preferred embodiment extend transversely across the pad.
  • the cells may be individually formed and restrained onto a base sheet to form the alternating pressure pad or may be made from top and bottom sheet material welded together to define alternately inflatable cells.
  • the cells 1', 1'' are supplied with fluid by channels 6 and 7 which run along the side of the cells. These channels have non return valve connections to a third channel 8 which feeds air continuously to the head cells 3 and the inflatable cells 4 under the head end of the pad via the air switch 12.
  • the inflatable cells 4 are positioned under the alternating cells for supporting the torso of a patient lying thereon, towards the head end, and arranged to inflate individually or together to provide torso height adjustment to enable ventilation access to the patients face.
  • These cells 4 may be "U" shaped to contour around a pneumatic automatic pressure adjuster(not shown) which may be used to maintain an optimum support pressure level.
  • Linked to the cells 4 may be a cell 5 that inflates to provide increased foot clearance. These cells 4 and 5 may also be inflated laterally to provide rotational therapy for the patient.
  • the first alternating cell 1' or 1'', next to the head cells 3 when deflated, may be converted to a static cell 9 so that constant support keeps the patient in a stable position.
  • a number of the remaining alternately inflatable cells 1' and 1'' for supporting the torso of a patient may be connected to the feed channels 6 or 7 via two position valves 10.
  • the valves 10 each comprise a body 20 extending through the individual pad cell 1' and channel 6 supplying air to it.
  • the valve body end also passes through the outer cover 30.
  • the valve body has two components, an inner component 21 inserted into the bore of an outer component 22, openings 23 and 24 are provided in the inner component and complimentary openings 25 and 26 are provided in the outer component with openings 23 and 25 interconnecting the cells 1' with channel 6. Openings 24 and 26 allow for venting of the cell 1'.
  • the openings 25 and 26 in the outer component are laterally offset so that in one position the cell may be supplied with air by the respective channel and in the other position the cell may be disconnected from the channel and allowed to deflate without affecting the adjacent cells.
  • valve 10 whilst allowing for individual cell deflation will isolate that cell from the channel 6 or 7 so that air is not lost from the system.
  • the valves 10 also pass through the outer cover and have a knob attached which will indicate the "Vent / Close" positions. As access to operating these valves is on the outside the risk of contaminating the mattress is minimised.
  • a head support is required to maintain the head in the prone position above the pad 1.
  • a "V" shaped cell 11 may be provided that at its apex supports the head and with its two ends secured under the patients arm pits supports the patient's shoulders and chest. It is possible to use mechanical cantilever type mechanisms with a mask allowing access to the face and throat of the patient to support the head. Another option could be a more complex structure having a fold away design, with storage within the pad.
  • Mounted to the frame could be a pressure reducing pad utilising either air, foam or gel agent whilst enabling access to the face and throat.
  • the compressor 2 supplies pressurised air to channels 6 and 7 feeding alternately inflatable cells 1' and 1''.
  • a rotary valve (not shown) alternates the supply of air to the respective channels 6 and 7.
  • the control of air supply to the rest of the cells is by means of an air switch 12.
  • the air switch 12 comprises two mating faces, one stationary 12a and the other rotatable 12b.
  • the stationary face 12a has an inlet 13 connected to channel 7, an inlet 14 connected to the compressor, outlet 15a to cell 9, outlets 15b and 15c to the cells 4 and 5 and outlet 15d to the head cells 3.
  • the other mating face 12b has arced grooves 16a and 16b that are configured to feed air to the different outlets 15a to 15d and cutaway sections 17a and 17b to exhaust the air from outlets 15a to 15b depending on its position with respect to the stationary face 12a.
  • the grooved quadrant 16a connects the inlet 14 to outlet 15d to supply continuous air to the head cells 3 and also groove 16b connects inlet 13 to outlet 15a to supply alternating air to cell 9.
  • the quadrant groove 16a cannot supply air to outlet 15d
  • cutaway section 17a is now in position over outlet 15d allowing the head cells 3 to deflate.
  • Groove 16b connects inlet 14 to outlet 15a to supply static air to cell 9.
