Motorized Tightening Mechanism for the Scoliosis Boston Brace

Abstract

An improved Scoliosis Boston Brace having self-tightening mechanism is disclosed, which tightens the brace around the patient's body with a motorized mechanism. The self-tightening mechanism makes it easier for the patient to tighten the brace around their body, and also eases the task of putting on/off, the brace. The components of the present invention includes a Boston brace, a worm drive, worm drive rack, a hexagonal peg, nylon strap, rivet, two parts epoxy glue, buttons and motor screwdriver. The worm drive and the worm drive rack are connected to the nylon strap, which is attached through rivet to the Boston Brace. The hexagonal peg helps in manipulating the worm drive, which determines the tightness of the brace; and the button attached to worm drive rack, helps to unclasp the mechanism when taking off the brace.

DETAILED DESCRIPTION OF THE DRAWINGS

[0024] The present invention discloses an improved Scoliosis Boston Brace having self-tightening mechanism, which tightens the brace around the patient's body automatically with a motorized mechanism, without any human intervention. The elimination of manual tightening by the present invention, paves way of firm and correct tightening of the brace, which helps in increased comfort for the patients.

[0025] With the help of the present invention, the patients can make use of automatic tightening technique which helps to tighten the Scoliosis Boston brace to the maximum degree.

[0026] The components of the present invention includes a Boston brace, a worm drive, worm drive rack, a hexagonal peg, nylon strap, rivet, two parts epoxy glue, buttons and motor screwdriver. The present invention can be understood in detail with the help of drawings.

[0027] Referring to FIG. 1, it is shown that the Boston brace with self-tightening motor mechanism constructed according to the present invention wherein the brace is represented by the reference number 1. The boston brace 1 has front side 2 and back side 3. The boston brace 1 is made up of outer layer of substantially rigid material like high density polyethylene (HDPE).

[0028] The worm drive element 12 used in the present invention, which consists of the worm drive rack 6 and the worm drive 5 itself, which serves as the control for the tightness of the brace and determines how much pressure is applied. The worm drive 5 and the worm drive rack 6 of the present invention are connected together by the two part epoxy glue 13. The worm drive element 12 is attached to the nylon fastener straps 4 that are wrapped around the brace body 1 which is attached through rivet 7 to the Boston brace 1.

[0029] Referring to FIG. 2, the back side 3 of the Boston brace 1 is shown. The boston brace 1 in present invention is un-segmented structure such that it completely wraps around the patient's torso with two edges 14 and 14a that slightly overlap and thus seal the brace at the back side of the patient along the spine. The brace is sealed by wrapping of the nylon fastener straps around the brace body 1 and are fixed on the brace with the help of rivets/screws 7.

[0030] Referring to FIG. 3, it shows the side view of the boston brace 1. The side view shows the inside curving 15 of the brace at the bottom of the boston brace 1. This curve serves the purpose of accurate fitting along the torso of the patient such that the curve fixes around the waist of the patient.

[0031] The worm drive 5 and the worm drive rack 6 of the present invention are connected together by the two part epoxy glue 13, which is in turn connected to the nylon strap 4. The nylon straps 4 connects the drive 5 to the brace. This arrangement is attached through the rivet 7 to the scoliosis boston brace. The hexagonal peg 16 makes it possible for the motor screwdriver 17 to manipulate the worm drive 5, which determines the tightness of boston brace. The motorized screwdriver 17 is used to turn the hexagonal peg 16, which is the main driving force that actually moves the worm drive 5, thus tightening the brace 1.

[0032] FIG. 4 is the front view of the scoliosis brace, where the scoliosis brace is in open position. The scoliosis brace 12 when in open position, discloses the nylon straps 13 which are in open position. The scoliosis brace 12, comprises of the nylon straps 13 and the worm drive rack 14, which are measured and cut according to required length, and the worm drive rack 14 is attached to the nylon strap 13 at two position using two part epoxy glue and the rivet. The scoliosis brace 12 also has buttons which are glued to the scoliosis brace 12 using two part epoxy glue, where the other side of the button is attached to the worm drive, which are also in open position.

[0033] With the help of above components, the scoliosis Boston brace can be assembled and the patients can use it to treat scoliosis.

[0034] In order to set-up the scoliosis boston brace, all the above mentioned components of the present invention has to be gathered together. The nylon strap 4 and the worm drive rack 6 has to be cut according to the required length; the worm drive rack 6 has to be attached to the nylon strap 4 using two part epoxy glue 13 and the rivet 7; the nylon strap 4 has to be attached to the boston brace 1 using rivet 7. The same steps are repeated to connect the bottom strap as well in order to assemble the scoliosis boston brace. The worm rack 6 has to be cut to the preferred measurement, which directly correlates with the range of pressure that the worm drive 5 will be able to provide. Similarly the nylon strap 4 has to be cut the preferred measurement so that it fits to wrap around the brace, all the way past the opening in the back. Finally the hexagonal peg 16 has to be attached to the motor 17 so that the user can easily move the worm drive 5. This completes the assembly of the scoliosis boston brace of the present invention.

[0035] The technology used in the present invention provides a more efficient solution for the scoliosis problems. In order to operate the scoliosis boston brace, the user would have to attach the hexagonal peg which is connected to the motor, to the worm drive, and then turn on the motor to navigate the worm drive along the worm rack. This mechanism tightens the brace automatically. When the user would have to remove the brace, the motor has to be turned in the opposite direction, which loosens the worm drive, until the worm drive and worm rack are disconnected from each other.

[0036] The scoliosis boston brace is a basically type of thoraco-lumbo-sacral-orthosis (TLSO), which is a back brace primarily for the treatment of idiopathic scoliosis. The Scoliosis Boston brace comprises of an outer covering preferably made of high density polypropylene, polyethylene foam, or plastic. The Scoliosis Boston brace is corrects the curves in the lumbar or thoraco-lumbar part of the spine. It is primarily designed in such a way as to keep the lumbar area of the body in a flexed position by pushing the abdomen in and flattening the posterior lumbar contour. The brace exerts pressure at certain areas of the body in order to provide relief from the pain.

[0037] According to the present invention, the manual tightening the brace is inconvenient and imprecise. The scoliosis boston brace described in the present invention is automatic, easy to put on or wear and tighten. The brace is highly accurate as it relies on technology rather than manual tightening. The self-tightening mechanism of the scoliosis brace ensures that the brace is tightened firmly, which leads to a higher chance of brace success and helps to avoid spine surgery.
