Definitions

  • the present invention relates to an inflatable head support device, pillow type. More particularly, the present invention relates to a head support device consisting of cells able to be inflated with air.
  • the present invention therefore relates to the technical field of support devices of the mattress or cushion type, for supporting the body of a person or part of the body of a person lying down.
  • Therapeutic mattresses consisting of inflated air cells, in particular coil-shaped cells extending transversely with respect to the longitudinal direction of the bed on which the mattress is intended to be applied, said cells being fed with air by means of an air pressure regulating system making it possible, as appropriate, to differentiate the air pressure inside the cells in different zones of the mattress according to the parts of the body resting on said areas of the mattress so as to homogenize the interface pressure on the different parts of the body.
  • These mattresses in particular make it possible, depending on the number of inflatable elements used, to individually control the pressure and thus the filling of the inflatable elements in the different zones of the mattress to provide a distribution of the interface pressure adapted to the level of each of the body parts of a patient, thanks to a device for regulating the inflation / deflation of the cells.
  • an airbag having different cells arranged side by side longitudinally with lateral cells of greater height, so as to create a wedging of the head in a gutter.
  • the object of the present invention is to provide a complementary device of the pillow type to fight against pressure ulcers, on the one hand, but also, on the other hand, to facilitate the movements of the head and neck required for the interventions of the nursing staff for the care, more particularly at the level of the head but also in other parts of the body.
  • the succession of cells of increasing height of the central compartments creates an inclined plane and a comfortable progressive elevation of the head.
  • the cells of the small branch of the L side compartments can support the neck, filling the gap between the two points of contact: occiput and shoulder height.
  • This arrangement allows the device in the inflated state to better support the head relative to the neck by avoiding the tilting of the skull backwards below the neck and thus relieve the vertebrae of the neck and promote good blood supply to the head.
  • the greater number of said cells of the central compartments added to the small branches of the lateral compartments is to make contact of the skull on the reduced surfaces delimited in the two axial directions XX 'and perpendicular direction YY' in larger numbers, which increases the patient's comfort at the risk of pressure ulcers.
  • This configuration according to the invention also has the advantage of being able to adopt a good positioning of the head in different positions.
  • the head is supported at the neck or neck by the two small branches of the two Ls of the lateral compartments and the skull tilts backwards, the chin and throat being, on the contrary, tipped up.
  • This position facilitates the intubation procedure in the trachea of a patient lying on a mattress when the device is used in a hospital or on a therapeutic mattress or bed.
  • This configuration of the head support device with the deflated central compartments is also useful for washing the head and hair of a patient or performing care, by inserting a tray in the deflated central area below the patient's skull.
  • This laterally pivoted head position is advantageous for performing care in the oral sphere with heavy equipment which must be approached at the maximum of the mouth and, if necessary in part resting on the bed, such as intubation equipment, nasal probe or gastric tube.
  • This laterally pivoted head position is also advantageous when it is necessary to pivot the patient's entire body for intervention at the occipital or back level, for example and, generally, to avoid excessive pressure on the patient. skin of the patient that can generate pressure ulcers or treat said pressure sores at the occipital level or on the posterior surface of the patient, in particular at the level of the sacrum or the heel.
  • the device according to the invention thus makes it possible to prevent or fight against pressure ulcers in a supplementary way compared to a simple therapeutic mattress of the prior art, as described above.
  • An inflatable air device has advantages over pillows of textile or synthetic foam, generally used in hospital beds. Firstly, the device according to the present invention has a greater lightness and reduced size when stored in the deflated state. On the other hand, it is possible to produce such devices from a simple envelope of plastic or impermeable material, which results in the manufacturing cost is significantly reduced compared to pillows filled with textile material or synthetic foam. Last but not least, the costs of use are significantly reduced because it is possible to wash the device between two uses and, therefore, to reuse for different patients unlike foam pillows in particular.
  • said central compartments comprise means for limiting their expansion in width.
  • width means the dimension in the perpendicular direction YY 'to said direction of the central axis XX'.
  • This means of limiting the width may consist, in particular of external connecting means between the central compartments between them on the one hand and between each central compartment and said large branch of the lateral compartment which is adjacent to it or by means of internal connections to the central compartments, such as spacers including a strip of fabric, bringing together the opposite faces of each said central compartment in said direction YY ', perpendicular to the direction of the central axis XX'.
  • said central compartments are, on the one hand, interconnected and, on the other hand, connected to said lateral compartments, along their adjacent sides, extending into said direction of the central axis XX ', preferably connected by welding.
