Definitions
- the present invention relates generally to back supports, and more particularly, to a novel back support having a gel pad and an inflatable bladder to press the gel pad against the lower back of the user.
- U.S. Pat. No. 4,622,957 discloses a therapeutic corset having an elongated support surface formed from material which is bendable when subjected to forces encountered thereby.
- a flexible cover is disposed on the support surface and secured thereto along its edges to form an envelope.
- the envelope has a plurality of cells, such that when the envelope is inflated, it assumes a predetermined curvature such as a crescent.
- the corset is secured around a user, the envelope is held adjacent the sacrum lumbar and thoracic region of the body. Since the corset is formed from a relatively inelastic belting material, inflation of the envelope will exert a force against the above-mentioned body region.
- the envelope as described above has a plurality of vertical ribs which form the series of intercommunicating inflatable cells.
- the vertical ribs cause the envelope to shrink thereby insuring the tabular ribs of always conform to the anatomy during a full range of movement.
- U.S. Pat. No. 4,682,587 (Curlee) which discloses one such envelope
- U.S. Pat. No. 4,682,588 (Curlee) which discloses a vertical stack of interconnected envelopes.
- a disadvantage and limitation of the above device is that the inflatable envelope is secured adjacent the body by relatively inelastic belting material. Such belting material if improperly secured about the torso may shift in position, negating the therapeutic effects of the corset, and also causing discomfort to the wearer.
- a back support includes a first pad having a gel-like substance contained therein and an air bladder co-extensive with, and juxtaposed to, the gel pad.
- the back support further includes means for supporting the gel pad in firm engagement against the lower back of a user and means for inflating the air bladder to press the pad against the lower back.
- the gel pad may further be removed for heating or cooling and reinserted prior to use for hot or cold therapy.
- the air bladder has three chambers so that the user may adjust the pressure applied on the back according to the contours of the user's back.
- two inner air bladders are provided, one on either side of the spine of the user, and a third, larger area, inflatable bladder is located behind the other two bladders to support and supply directed pressure to the gel pad and/or directly to the patient's back.
- the back support further includes an electrical heating elements or wires disposed within the gel pad.
- External power either from a battery pack or from a wall outlet may supply current to the heating element.
- a variable transformer allows the user to adjust the current in the heating element to adjust temperature.
- the broad belt members extending forwardly from a lower back pad, extend upwardly over the hips, and engage one another across the lower stomach area.
- the resultant geometry of the orthopaedic support includes the fact that the projected centerlines of the two broad belt members make an angle of about 30 degrees to sixty degrees with respect to one another. It is also noted that patients complaining of lower back problems often have protruding stomach areas.
- the engagement of the broad straps across the lower stomach area has the further advantageous factor of providing a corset-like upward pressure on this lower stomach area.
- the inflatable bladder assembly has integrally associated straps which extend outwardly in alignment with, and exterior to, the main broad resilient belt members.
- these straps extend through slots through the main resilient brace construction on both sides of the main support area.
- the brace may then be initially mounted on the patient and secured by large VELCRO pads or the like, and the inflatable bladder straps may then be pulled firm, and secured to the main broad brace belt members, also by VELCRO tabs or the like.
- the three inflatable bladders may then be inflated to apply the desired pressure to the lower back area.
- VELCRO is a trademark, and the products sold under the VELCRO trademark are mating fabric pads, with one of the pads having its surface provided with a fine array of closely spaced outwardly protruding hooks, and the other of the mating pads being outwardly extending loops or other material with which the hooks may engage.
- the multiple inflatable bladder assembly has a right-hand section, a left-hand section, and an overall section, which are separately inflatable. In some cases where lower back alignment correction is needed, this may be accomplished by providing more inflation to the left bladder and less to the right, or vice-versa.
- the features outlined above are implemented by a unit which has wide belts Q made of elasticized material, and pockets for selectively holding the thermal therapy pad and the inflatable bladder.
- the .[.main support.]. .Iadd.body member .Iaddend.portion of the assembly which is formed of two-way stretch material such as that found in a wet suit, with a central layer about 1/8 inch thick of foam rubber such as neoprene and two outer cloth, preferably nylon layers.
- the multiple bladder assembly is formed of cloth coated with plastic such as urethane to provide limited resiliency and an airtight construction, and is located on the main .[.support.].
- the bladder assembly straps are firmly secured to the main .[.support.]. .Iadd.body member .Iaddend.prior to inflation.
- the third and optional portion of the simplified assembly is (3) the thermal therapy pad which may be simply affixed to the inner surface of the bladder assembly by mating Velcro elements.
- the stiffer type of VELCRO material (the hooks) are mounted on the thermal therapy pad, and the softer loop type material is mounted on the bladder assembly, so no discomfort is encountered by direct engagement of the back of the patient by the inner surface of the air bladder assembly.

- the composite layer 292, as shown in FIG. 19 is about one-eighth inch thick, and includes a central core of foam rubber 294 to which are bonded layers 296 and 298 of finely woven cloth, such as nylon.
- the resultant composite material is known and is used for making "wet suits" for winter surfboarding activities, or the like.
- the material is flexible and resilient, and it will stretch about 20 percent with moderate forces of 5 to 20 pounds per inch.
- the main area for the application of thermal therapy and pressure is the lower back, and the two main belt-like members extend upwardly and forwardly around the waist joining at the lower stomach area.
- the outwardly directed angles between these centerlines is about 30 degrees for one embodiment, and about 45 to 55 degrees for the other embodiment. More specifically, with reference to FIG. 14, if the centerlines of the two arms of the belt member are extended so that the centerlines cross each other, there are two equal outwardly directed angles, and equal upwardly and downwardly directed angled.
- the overall size of the symmetrical unit is about 36 inches

- the flat pump 208 may be provided with a VELCRO pad 211 for securing it to the assembly.
- the inlet and valve assembly 232 may include check valves and relief valves for each of the multiple bladders. If desired, the pump 208 may be permanently coupled to the inlet and valve assembly 232 may be provided with internal control for directing air to the desired bladder. or alternatively, the pump may be manually shifted to the desired inlet channel.
- the main body .Iadd.member .Iaddend.of the back support may be formed of a flexible material with relatively little of no substantial stretch; in fact, the angled configuration of the brace permits practical use of this type of back support using such materials. Accordingly, the present invention is to be defined solely by the scope of the following claims.
