Abstract
A shell-like orthopedic brace is described which is divided into two halves and is prefabricated in various shapes and sizes. The measurement and applications of this device is used as required on any member of the patient's body. Two molded parts or shells are formed to the shape and size of the specific member or limb of the body where a brace is needed. The inside of each molded part or shell is fabricated to include cushionlike supports or suchioned areas of a soft material that are joined to the shell. These cushioned areas are placed between grooves in the shell. To provide air circulation, holes are positioned equally along the grooves and are opened through the shell. Construction for the utmost safety, the left and right parts come together precisely. This construction makes the device very stable.

Description
Background of the Invention
1. Field of the Invention
This invention relates to a shell-like orthopedic brace which is produced in two halves more particularly to an orthopedic brace for curing the limbs of the human body and that of animals.
2. Disclosure Information Statement
In the past when a fracture occurred, to correct the situation the bone was set and a plaster cast was applied to allow the fractured area to fuse. In this manner, a technician working with the only medium available, namely plaster, first wrapped the broken limb in a bandage, then coated the site with plaster, and waited for the plaster to dry and cure.
Over a period of time, the formation of plaster casts has become the accepted way of curing fractures and an art practiced by many in the medical field, including orthpedic doctors, technicians, and nurses, and others on the orthopedic staff. While widely practical, it is well known that, when needed for long periods of time the plaster cast is inconvenient and cumbersome. Other disadvantages of the plaster cast are that plaster casts take a long time to prepare and must be applied by an orthopedic professional. When the cast is finished, the patient is carrying and supporting the weight of a closed heavy plaster cast. Other problems arise, such as personal hygiene, physical discomfort and psychological problems.
More specifically, with the plaster cast, it is difficult to nurse the fracture with medication or to observe the curing process. Further, it is difficult for the limb to breathe in a cast because there is no circulation or air. A patient with a plaster cast is also limited as to the extent of the personal hygiene he can manage as he must be careful not to get the cast wet. The difficulty with the psychological and the physical effects of the plaster cast is frequently related to the weight of the cast, the length of time the cast is used, and, the itching of the irritated areas.
Taking into consideration all of the above, one can see the advantages of the orthopedic brace fabricated in two shells the description of which follows.
Summary of the Invention
The shell-like orthopedic brace of this invention is essentially constructed in two halves which combine of the following elements:
Two shells (halves) made to the form and measurement of the limb applied.
Inside each half (shell) are support cushions of a soft material attached to the shells and located between grooves.
Air holes are placed in anarray through the body of the two shells.
Constructed for safety the precision joints attach left and right half-shell forms to each other and thereby provide stability.
The orthopedic brace constructed in two sections is constructed so that one section is the mirror image of the other. The brace is preferably constructed of PVC, polyvinyl, polystyrene, or other reinforced plastic having the necessary physical properties.
The cushions, the grooves and the air holes are made in the configuration as shown, or variations thereof with an increase or decrease of holes and grooves as required by the application.
The cushioning (soft section) is fabricated from rubber, rubber foam, or plastic foam.
The oppositely corresponding portions of the border flange fit together reversibly in the two halves or sections. The holes are shown on the flange of the two shells.
The shells are optionally constructed with the bands or belts that are permanent which optionally may be used as the locking mechanism.
When compared to the conventional plaster cast, the orthopedic brace constructed in two halves, has more advantages like these:
Simple construction and low cost
Reduction in waiting time by 75%
Reduction in preparation time by 80%
Reduction in the number of steps administered
Ventilation to the injured limb through the air holes provided
Easier access to the injured limb for nursing, medical reasons, opening and closing
Re-usability of the orthopedic brace.
Reduces (1) precautions a patient must take with a cast. (2) Danger of misuse of plaster cast and (3) psychological problems connected therewith.
As stated hereinbefore the shell-like orthopedic brace has many advantages and can be readily applied in a variety of specific limbs. Other advantages of the orthopedic brace of this invention will become obvious from the reading of the detail description which follows, especially as the brace can be constructed in various forms and measurements and can be applied by relatively non-skilled workers to the limbs of the patient.
Brief Description of the Figures
The invention is more readily understood by viewing the figures that follow, in which similar parts are afforded the same reference designations in the various views.
FIG. 1 is a side view of the orthopedic brace.
FIG. 2 is a cross-sectional view of the orthopedic brace of FIG. 1, along section line II--II.
Description of the Preferred Embodiment
Referring to FIGS. 1 and 2, an orthopedic brace for the human leg is shown, and referred to generally by the reference numeral 1. The orthopedic brace has an outer portion, inlcuding the border and flange. The orthopedic brace is structured to include two connected half shells or forms as shown. The orthopedic brace 1 is structured to include air holes 3. The two halves are connected by belts 4. The interior of the shells are constructed to include cushions of foam rubber 5. Channels or grooves 6 provide an airway along the length of the brace. Closure devices 7 and 8 indicate respectively the system for closing the orthopedic brace and attaching the "L" or "R" construction the one to the other. Semicylindrical heel supports 9 are shown attached to the heel portion of the leg brace for protecting the heel from shock and improving equilibrium.
In operation, when the brace is applied to the leg and is placed to the fracture correctly, the cushions 5 give the necessary precise pressure to the injured area. It has the ridged contact with the brace as with the skin. The function of the holes 3 and the grooves 6 is to assist in a continued flow of air into the brace and ultimately the injured area.
Although the best mode of the invention has been described herein in some detail, it has not been possible to include each and every variation. Those skilled in the art of constructing orthopedic braces will be able to make slight variations in the mechanical arrangement suggested hereby without departing from the spirit of the invention and still be within the scope of the claims appended hereto.
