Definitions

  • the present invention generally provides a therapeutic mattress.
  • the therapeutic mattress has a base layer, a patient support layer above the base layer, and an encasing over the base layer and the patient support layer.
  • the therapeutic mattress is provided to assist in preventing bed sores and decreasing existing bedsores on patients.
  • the patient support layer has a plurality of air cell sections, the internal air pressure of which can be independently monitored and adjusted.
  • FIG. 23 is an exploded perspective of the therapeutic mattress of FIG. 21 with the mattress cover removed;
  • FIG. 28 is a schematic view of one embodiment of an adjustable therapeutic mattress
  • the patient support layer 110 is the uppermost layer of one embodiment of the bed system 10 or mattress and includes a head section 112, a torso section 114, an activation section 116, and a lower body section 118.
  • the activation section 116 is positioned within the torso section 114 and is configured to apply alternating pressure, percussion and/or vibration forces to treat the patient.
  • the entire patient support layer 110 may be an activation section 116, such as with an full alternating pressure mattress.
  • the torso section 114 and head section 112 are combined as an integrated unit that receives the activation section 116.
  • the head section 112 includes an air supply fitting 134 and an exhaust or relief fitting 138. As explained herein, with any section of the patient support layer 110 the inlet port 134 may also be utilized as an exit port such that only one port per chamber is necessary.
  • the blower assembly 310 supplies air via the plenum layer 210 or directly to the cells 120 in the head section 112 to support the patient's head when it rests on the patient support surface 127.
  • the fitting 134 depends from a lower surface of the base 122.
  • the head section 112 has a three by eight array of cells 120 providing a rectangular configuration to the section 112, however, the precise number of cells 120 in the array can vary as well as the resulting configuration of the head section 112.
  • the cells 120 and the base 122 are formed from urethane, neoprene, or any other material having similar strength and durability traits, wherein the material thickness is preferably greater than 10 mils.
  • the cells 120 within the activation section 116 are separated into at least two groups—Group A and Group B— whereby alternating pressure, alternating percussion and/or vibration and/or a flotation force is applied to the patient on a per group basis.
  • Group A the cells 120 in Group A are in fluid communication with each other by a number of channels 140
  • the cells 120 in Group B are in fluid communication with each other by a number of channels 142, but the cells in Group A are not in fluid communication with the cells in Group B.
  • the channels 140, 142 connect to the lower portion 128 of each cell 120.
  • each sub- cell member 717, 718, 719 has at least one orifice 727 that is operably connects that sub-cell to the adjoining sub-cell or sub-cells.
  • Each middle sub-cell 718 has a bottom wall with an orifice 727 that is aligned with the orifice 727 in the bottom sub-cell 710 to define the remaining segment of the cell stack fluid passageway.
  • the passageway allows air to be transmitted between the sub-cells 717, 718, 719 of the cell stack 721.
  • the blower assembly 310 can include valve means, such as a one-way valve, to maintain a constant or static pressure in any of the bladders 212, 214, 261 and the activation section 216. It is understood, however, that any of the plenums may be eliminated or replaced with tubing directly from the blower/air supply to the cells.
  • valve means such as a one-way valve
  • the blower assembly 310 is configured to communicate with a combined control panel and user interface (not shown) such that an operator can control the operation of the blower assembly 310 and the settings of the bed system 10. Depending upon the settings entered by the operator in a control panel or other control member, the blower assembly 310 can supply air on a substantially constant basis to the plenum layer 210 and the patient support layer 110 through passageways, such as supply lines 222, 228, 232 and the tubes 240, 242. While the blower assembly 310 supplies air to the plenum and support layers 110, 210, the activation valve assembly 410 controls the quantity of air exiting the activation section 116.
  • the blower assembly 310 can be mounted to any portion of the bed frame or the support frame for the bed assembly.
  • the force application results a dynamic system with pneumatically powered cell groups where the pressure therein is actively adjusted by the valve assembly 410 and the control panel.
  • the blower or pump 310 is in fluid communication with the inlet and outlet ports 134, 138 of the mattress 110 and supplies air pressure to the cells 120 as appropriate in the mattress 110.
  • each of the group of cells 120 may have only an inlet port 134 and air may be able to be injected and exhausted from the same port 134 without requiring a separate exit port 138.
  • the blower or pump 310 is in fluid
  • a electrical connector 930 is electrically positioned between the control unit 920 and the pressure transducers PT and the valves V within the sub-bolsters 918.
  • the control unit 920 can be secured to any portion of the bed frame or support structure, including under the mattress 910.
  • the user control interface 928 can be operably mounted in a similar manner, including to one of the bolster assemblies 912, 914.
  • the therapeutic mattress 1010 generally comprises a covering or encasing 1012 housing a first or base layer 1014 and a patient support layer 1016.
  • a covering or encasing 1012 housing a first or base layer 1014 and a patient support layer 1016.
  • patients confined to a bed for a long period of time frequently develop pressure sores, which can be known as decubitus ulcers or the more commonly referred to bedsores.
  • the various embodiments of the therapeutic mattress 1010 described herein assist in preventing or decreasing the potential for such bedsores for some patients, in conjunction with proper care and nutrition.
  • the air components 1060 may be made of various materials, including, but not limited to, neoprene and urethane. It is also understood that the same type and/or configuration of air components 1060 may not be utilized in each zone or section of the mattress 1010. Instead, a combination of different air components 1060 may be utilized in different sections or zones of the mattress 1010. For example, in one embodiment air component 1060 having the larger air cells 1078 may be utilized in the head, seat and knee sections 1050, 1054 and 1056, and an air component 1060 having the narrower air cells 1078 may be utilized in the foot section 1052 to provide a varied therapeutic benefit for the patient.
  • valves may be connected to the air components to
  • the reservoir tank 1200 gauge 1204 An operator should check the reservoir tank 1200 gauge 1204, however, periodically to ensure that sufficient pressure is retained in the reservoir tank 1200 to operate the mattress 1010 system.
  • the air pressure in the reservoir tank 1200 decreases below a certain threshold greater than the air pressure in the air components 1060, the air pressure in the reservoir tank 1200 can be increased through a common compressor. Accordingly, such a system provides a purely mechanical fluid system to retain the air component 1060 sections of the air mattress 10 at an appropriate level.
  • the vent valves/regulators 1206 are adjustable to allow air to automatically and independently exit out of the air component 1060 sections as required.
  • the acceptable differential air pressure range is from approximately 17mmHg to approximately 25 mmHg when the patient is on the air component 1060.

Abstract

La présente invention concerne un matelas thérapeutique ayant une couche de base, une pluralité de sections alvéolaires séparées, une source d'air et une soupape. Les sections alvéolaires séparées ont une pluralité d'éléments alvéolaires interconnectés de manière fluidique s'étendant verticalement à partir d'une paroi inférieure. Les éléments alvéolaires des sections alvéolaires peuvent être déplacés de manière indépendante dans une pluralité de directions. La soupape est connectée de manière fluidique à la pluralité de sections alvéolaires séparées. La source d'air est connectée à la soupape de sorte à augmenter de manière indépendante la pression de l'air dans les sections alvéolaires jusqu'à une pression souhaitée de l'air.
