  • the cells 16 are filled with a gel 18 so as to provide weight to the weighted body 14 located within the cover 12.
  • the cover 12 is shown separately in Fig. 2 may comprise two quilt layers
  • Each quilt layer may comprise a top fabric, wadding (an insulating material made of cotton, polyester, wool and/or mulberry silk) and a bottom fabric.
  • the top fabric may be coloured and ornamented with a pattern or other motifs for aesthetic appeal, whereas the bottom fabric may be a plain white or other coloured material (as it will not be visible to a user), in order to reduce the cost of manufacture of the cover 2.
  • the amount of wadding can be increased or decreased depending on the desired thermal resistance of the cover 12.
  • the top and bottom fabric may be made of cotton, for instance.
  • top fabric and the bottom fabric are stitched together with the wadding in between. Stitches may be made around the permitter of the top fabric and the bottom fabric. Stiches may also be made at regular intervals forming a grid and across the top fabric and bottom fabric.
  • the two quilt layers are placed on top of each other with the bottom fabric facing outward. Stitches are made around three of the four sides of the two quilt layers to join them together.
  • Press studs comprising a cap stud 22 and a socket 24 are used to fasten the cover 12 to the weighted body 14 so as to hold the weighted body 14 in place within the cover 12.
  • the cap stud 22 is attached to the cover 12 (see Fig. 2) to engage the sockets 24 which are attached to the weighted body 14 (see Fig. 3).
  • the cap stud 22 and socket 24 are located at the corners of the cover 12 and the weighted body 14 and also along the sides of the cover 12 and the weighted body 14.
  • the two quilt layers are then turned inside out through the side which is left unstitched, so that the top fabric of the two quilt layers faces outwards.
  • a zipper 20 may be placed on the side of the cover 12 which is left open.
  • the weighted body 14 may be inserted into the cover 12 through the zipper 20.
  • the weighted body 14 is shown in Fig. 3 at a preliminary stage of construction.
  • the weighted body 14 may be constructed from two sheets of a thermoplastic material, such as nylon (polyamide) or any similar materials (e.g. low-density polyethylene or polypropylene) that are fluid impermeable and able to be washed and resist high and low temperatures.
  • the two sheets are cut to the required size and then welded together by sending a high frequency current through the two sheets when placed between two sealing electrodes or dies.
  • the cells 16 may be arranged in a pattern other than that shown in Fig. 3, but preferably the pattern is regular so that the weight within the blanket 10 is evenly distributed so that the blanket 10 is comfortable to use.
  • the cells 16 are preferably square shaped so as to maximise the area of the weighted body 14 which is able to be filled with gel 18, but may also be round, rectangular or any other shape.
  • the cells 16 have passageways 28 arranged in columns throughout the length of the weighted body 14, so as to facilitate the manufacture of the weighted body 14.
  • a reservoir 30 filled with the gel 18 is connected to a pump 32, which is attached to a hose 34 which is connected to a tube 36.
  • the tube 36 is inserted along a column through the passageways 28 and the gel 18 is pumped through the tube 36 and deposited into the individual cells 16 until all of the cells 16 are filled with gel 18 as shown in Fig. 6.
  • passageways 28 down the length of the weighted body 14 also aids the user to move some of the gel 18 up and down the weighted blanket 10, whilst preventing the gel 18 from moving sideways in use overnight as it would be inclined to do if the passageways 28 extend laterally instead of or in addition to lengthways.
  • a suitable gel 18 may be a mixture comprising about 75% carboxy- methyl cellulose, about 20% propylene glycol and about 5% water.
  • An industrial blender may be used to mix the components of the gel 18 for approximately 2.5 hours.
  • the gel 18 is adapted to be heated or cooled.
  • the weighted body 14 may be placed in a clothes dryer or a bath filled with hot water to heat the gel 18 which will retain the heat for some time within the weighted body 14.
  • the weighted body 14 may also be placed in a refrigerator in order for the gel 18 to be cooled.
  • the weighted body 14 may also be heated without first removing the cover 12 when a clothes dryer is used to heat the device.
  • a pump 32 is used to inject the gel 18 into the cells 16 (see Fig. 5).
  • the pump 32 is turned on for a certain length of time, a certain amount of gel 18 will be injected into each cell (depending on the strength of the pump 32). The amount of time the pump 32 is turned on will determine how much gel 18 is pumped into each cell. For instance, leaving on the pump 32 on for 4 seconds will deposit 23.6 grams of gel 18 into a cell 16.
  • the seal 38 is made along the bottom edge of the weighted body 14 (see Fig. 5) to retain the gel 18 within the lower row of cells 16.
  • the surface of the weighted body 14 is waterproof so that it may be washed or wiped down after use.
  • the weighted body 14 may be removed from the cover 12 via the zipper 20 so that the cover 12 may be put into a washing machine.
  • the weighted body 14 may also be wiped clean with warm soapy water.
  • the weighted body 14 of the present invention may be used with or without the cover 12 to provide deep pressure touch stimulation therapy to patients having any one or more of the following conditions: Autism, Attention Deficit Disorder, Attention Deficit Hyperactivity Disorder, Bi-Polar Disorder, Dementia, Pervasive Developmental Disorder, Sensory Processing Disorder and other conditions which cause anxiety, stress and agitation. Whenever patients having these conditions are in a state of agitation or distress, the patient may be placed under the weighted body 14 or wrapped in the weighted body 14 in order to calm the patient. The pressure applied by the weight of the weighted body 14 enables the patient to feel secure.
  • the size and weight of the weighted body 14 for use in treating patients can vary depending on the degree of pressure required to be applied. It has been found, however, that the weight of the weighted body 14 should be approximately 1 1 % of the weight of the patient. Further, the length of the weighted body 14 should be approximately 15% longer than the height of the user and the width of the weighted body 14 should be approximately 80% of the height of the weighted body 14.
