Abstract

Polyurethane support bandage for the treatment of fractured persons, characterized by a double tube made of flexible synthetic or textile material, into which a polyurethane rigid foam in liquid form is filled by a valve, which fills out and hardens the tube within seconds. The tube is created by means of a zipper of the frakturgeschaedigten person. Thus, the constant control and accessibility of the fracture by the doctor is guaranteed. The polyurethane foam used is roentgenfaehig, in contrast to the plaster used to date, a good insulator, very light and does not absorb water.

1. Title of the invention:

Support bandage made of hard foam for fracture treatment

2.-Areas of application of the invention:

The present invention relates to a support bandage used for fractured persons or animals.

  , , which can be based on rigid foams, preferably made of polyurethane, which is surrounded by a flexible 'double tube and the fractured fractured limb envelops and benefits compared to previously used support braces,

Characteristic of the known technical solution:

So far fractures are u.a. supported with gypsum or shut down. The following disadvantages of a plaster cast, such as:

- high weight

- high effort when creating and losing weight

- no reusability

- Moisture sensitivity

- no protection against heat or cold (bad insulator)

- must be removed in principle during X-ray

- poor adaptation to the shape of the limb when putting on (slipping, etc.)

are determined by the material used and the associated technical solution.

The present invention has for its object to provide an eil-times, effective support bandage made of hard foam, ur give by a flexible double hose, which has particular advantages, as in disasters and military conflicts as well as in the normal mediziniscl care of fractures and the like aforementioned violations take effect «

Object of the invention:

This object is achieved in that a double tube of a so-called "artificial skin", der.allseitig closed and only provided with a filling valve is filled with a rigid foam as stiffening body.

For advantageous to use a rigid polyurethane foam. The support bandage is designed so that a zipper makes it possible to remove and apply the bandage at any time in order to make the injury accessible to a medical examination

The 'invention will be explained in more detail below with reference to an application example shown schematically in the drawing. In the drawing, the application of a support bandage according to the invention is shown on a fracture-damaged arm

The arm 1 has a fracture 2 to _o The prefabricated double tube 3 is placed over the fracture and closed by a zipper 4 * Thereafter, a rigid foam system (in the case described based on polyurethane) through an injection valve 6 introduced «The foam fills in a short time Bandage, hardens and supports or restricts the limb (depending on the hard foam used, from a few seconds to a few minutes) ·
