Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an overshoe for orthopedic casting, such as an overshoe with water-resistant uppers.

According to the present invention, there is provided an orthopedic cast overshoe comprising a sole and first and second parts connected to the sole and adapted to receive the foot of an orthopedic foot cast. a toe cap that extends over the wearer's toes in use; The toe cap is made of a soft material that can be easily cut by hand using a knife or scissors and opened to fit the wearer's toes.

Preferably, the sole is fluid-tightly connected to the upper piece and/or the toe cap so as to surround the entire outer periphery of the sole. This upper piece consists of a left part and a right part, which may be overlapped along the front surface of the overshoe, and the back of either the left part or the right part is on the front side of the other part. On the other hand, for example, [Velcro
It is sufficient if it can be removably adhered with a cro) J (trademark) fastener.

Any semi-rigid rubbery plastic that can be molded into a suitable shape can be used for the toe cap, including, for example, polyurethane, polyvinyl chloride sea-molding compound, rubber [Wellingto
n) Synthetic thermoplastic rubbers based on vulcanized rubber or molding formulations, such as those used in J-boots.

Preferably, the toe cap is not attached directly to the upper (although, of course, it is attached to the upper through the sole), so that the toe cap is attached in a single cut in a horizontal plane just above the level of the upper surface of the sole. It becomes possible to remove the cap. In this case, it is particularly desirable for the upper to overlap the rearmost edge of the toe cap or to overlap a tongue attached to the toe cap relative to the upper to provide improved weather protection. The latter solution is particularly preferred in that the tongue is not attached to the instep, but is removable together with the toe cap if desired.

Preferably, the toe cap is not significantly more difficult than if it were prepared from polyurethane having a Ship-A hardness of about 601 and a thickness of about 4 mm. More preferably, at least the toe cap has a Shore A hardness of about 40 to about 60 and a thickness of about 2 mm to about 4 mm.
prepared from polyurethane with

In a particularly preferred embodiment, the sole, toe cap and upper piece are molded as a single piece from elastic rubber or plastic material. If a tongue is provided, it is preferably sewn onto the toe cap.

Preferred embodiments of the invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, the illustrated oversea includes a sole 10, left and right uppers 12 and 13, respectively.
Outer shell piece 1 comprising first and second parts in the form of
1, a toe cap 14, and a tongue piece 15. The sole 10, the uppers 12 and 13, and the toe cap 14 are all made of elastic rubber or plastics material.
For example, one-piece moldings made of polyurethane and t
7. The tongue 15, made of canvas, cloth, elastic rubber or plastic material, is a separate piece, but is sewn to the toe cap 14 along a line 16. "Vuelcro" zipper 17 is 13 on the front shell
When a patient's foot, placed in a plaster cast or similar bandage, is placed in the oversea, the toe cap 14 and the tongue 15 are Extends over the patient's toes and the top of the foot and its cast.

The upper 12 surrounds the tongue piece 15, and the upper 13 surrounds the upper 12. "Vuelcro" zipper 17
and 18 stick together and hold the overshoe securely over the cast. ``In this relative position, the overshoe provides excellent water repellency and protects the cast. For many patients, it will be the case that the oversea is worn for the entire life of the cast. However, despite the cast being in place, the patient's toe became swollen;
Or it could be torn, or the toe could require surgery. Such toes may become infected and may require disinfectant swabs, renewed dressings, or similar treatment. Other undesirable situations with toe pieces include incising the toe, or when it is desired to relieve pressure on the toe while still not abulating the patient.
Alternatively, there are clinical situations such as when Kirchner wires are used for internal fixation for metatarsal resections or toe fusions.

In such a case, it is not suitable to use an overshoe with a toe cap.

The present invention allows the toe cap 14 to still be used for such patients by cutting it off in a simple step. This can be accomplished by simply punching a hole in the toe cap 14 using a sharp knife or a pair of scissors and cutting it out along the line 20 that coincides with the knoll 10. In the area of the toe cap, the overshoe becomes very thick at the sole 10, where the tread is molded into the oversea to the line 20 where the toe cap begins.
It can be seen from FIG. 4 that although a thickness range of 2 to 4 mm is preferred, a thickness range of 1 to IQ mm is also possible. Since the toe cap and sole are prepared from elastic rubber or plastic materials, such as polyurethane, and the toe cap is thin, the process of cutting the toe cap is very simple. Next, toe cap 14 and tongue 15 are removed. The obtained over sea is
As shown in the figure. It can be seen here that the sole 10 extends continuously to the underside of the patient's toe. The sole thus continues its role of protecting the toe, keeping it dry, and providing support and grip.

The invention can be modified in various ways, for example by opening the upper piece 11 in different places to provide for the insertion of a cast into the overshoe, and if a tongue piece is present. It may be riveted or glued to the toe cap, or it may be integrally molded therewith.

It will, of course, be understood that the above description is given by way of example only, and that modifications in detail may be made within the scope of the invention.
