Description

Shoes for casts with combined and detachable protective cover {CAST SHOES WITH PROTECTIVE COVER OF ATTACHED/DETACHED}

The present invention relates to a shoe for a cast in which a protective cover can be combined and detached.

In general, if you have a fracture such as a broken or cracked bone in your foot, leg, or arm, or if your ligaments are stretched, wear a skin protection cloth called stokinette on the affected area and then apply several cotton balls over it. It has been treated through the Plaster of Paris procedure, in which a bandage for curing is wound several times and then hardened with a curing glaze. In other words, when water is added to the powder of calcined gypsum, it hardens quickly. Put the powdered gypsum on a bandage and soak it in hot water at 42~43℃ with a plaque applied immediately before use. Wrap it up and leave it for about 20 minutes to make the bandage firm. This is called a cast.

Therefore, in the case of a fracture such as a broken or cracked bone, if the cast is left for more than a month, the fracture will heal naturally over time.

Depending on the degree of fracture and sprain of the patient, either a splint cast using a splint or a hard cast type treatment is decided according to the opinion of an orthopedic surgeon. In addition, depending on the progress of the patient, there are cases where the patient is treated with a half cast after a cast, or by changing the cast from a half cast, or there are cases where the treatment progresses with one type of cast.

As such, as there is a case of using a splint during cast treatment, many cast shoes are manufactured in a design in which the front is open and the toes are exposed.

However, in the case of open cast shoes, there is a risk of bumping into obstacles or sharp objects or falling accidents when walking with swollen toes or toes exposed, and there is a problem that the toes are exposed to cold outdoor temperatures in winter.

Accordingly, in order to protect the open toe part, conventionally, toe protection type cast shoes formed to cover the toe part are also being manufactured. However, the conventional toe protection type cast shoes are uncomfortable when the patient bends down and wears them, and if the cast method is changed to a half cast after a ventilation cast, an open cast shoe without a protective cover has to be purchased again due to the use of a splint, etc. There is a problem of In addition, when treating a cast, it is usually treated to cover the toe with a bandage. If the toes are already wrapped in bandages, protective cast shoes to protect the toes are meaningless, rather inconvenient to wear protective cast shoes, and are double blocked from the outside by the bandages and protective cast shoes wrapped around the toes. There is a problem that inhibits ventilation.
