Abstract

Device (1) for measuring the foot / leg region of a patient for making in particular an orthosis, comprising two carrier elements (2, 3) arranged vertically one above the other, wherein on the lower carrier element (3) a measuring rail (7) in a guide ( 5) is arranged horizontally displaceable, whose from the guide (5) exiting end (12) is angled 90 ° in the horizontal plane, and the upper support member (2) to the lower rail (7) parallel in a guide (4) movable, approximately identical measuring rail (6).

Description

The The invention relates to a device for measuring the foot / leg area a patient for the preparation of a particular Orthosis.

Orthoses are body supportive aids for patients with, for example, fractures in the heel bone and hindfoot area, where it is important that in the recovery stage, the heel bone is positioned without pressure and free-floating. Such orthoses are for example from the DE 298 08 342 U known.

In order to the heel bone can take the above position is in the foot part of the orthosis a longitudinal arch support whose vertex is below the navicular bone (os navicular) must be arranged. Because this point is not in all patients necessarily at the same distance to the heel end, must be in front of the Production of the orthosis this distance is individually determined become.

Furthermore The vertical distance of the patients to be supported must be the same for each patient Wade from the ground as well as the horizontal distance of the calf back determined by the heel so that the finished orthosis to the patient not only the recovery progress guaranteed but also one good and comfortable seat.

Of the Invention is therefore based on the object, a device for To provide these measurements practically can be done simultaneously.

The Invention solves this problem according to the feature combination of claim 1, characterized in that the device consists of two vertically stacked, distance variable arranged carrier elements, wherein the lower carrier element a measuring rail in a guide horizontally displaceable is arranged, whose emerging from the guide end bent at 90 ° in the horizontal plane, and at upper support element parallel to the lower rail Slidable in a guide, approximately identical measuring rail.

The Device thus represents a gauge that is to be treated Foot is laid sideways. The place of the Os navicular forms the zero point of the subsequent measurements.

The under rail becomes with the leg angled by 90 ° from the back to the heel. On a scale the rail is read off the corresponding value.

• – der horizontale Abstand von dem zu unterstützenden Fußbereich zum fersenseitigen Ende des Fußes, sodass das Fersen- und Fußteil gefertigt werden kann und der Ort für die einzusetzende Längsgewölbestütze festliegt;
• – die Höhe des Orthesenschaftes;
• – der horizontale Abstand der Schaftschale vom Unterstützungspunkt.

By varying the vertical spacing of the two carrier elements, the upper measuring rail reaches the calf height, in which the orthosis to be manufactured rests with a shell of the orthosis shaft partially enclosing the calf. The upper measuring rail is applied to the calf from behind and the horizontal distance from the zero point is read on a scale on the rail. Now there are already three readings:

• The horizontal distance from the foot area to be supported to the heel end of the foot so that the heel and foot part can be manufactured and the location for the longitudinal arch support to be used is fixed;
• - the height of the orthosis shank;
• - The horizontal distance of the shaft shell from the support point.

Around also consider the different calf diameters of the patients to be able to claim 2 suggests that the upper measuring rail in plan view from above U-shaped, wherein the web connecting the U-legs is longitudinally displaceable is. Also the lower measuring rail for measuring the foot area can be formed in a U-shaped, also here the length of the U-legs interconnecting bridge length is displaceable (see claim 3).

At the legs angled 90 ° in the horizontal plane The guide rail is thus another L-shaped Element set, with an L-leg slidably formed is and the other L-leg parallel to the rail guide direction Foot tip runs.

The Displacement can, for example, by means of telescopic guide respectively. Other solutions are conceivable.

The U of the guide rail is laterally to be measured Wade applied and the distance between the U-thighs by means of a determined on the bridge scale. Analog is with the lower guide rail for measuring the heel width worked.

The obtained four or five dates are sufficient to a tailor-made To create orthosis.

According to claim 4 it is provided that the carrier elements by means of a provided with vertically stacked holes Plate at different distances from each other connected to each other are.

However, it is also conceivable that the two support elements are telescopically or in suitable guides relative to each other, so that a continuous height adjustment allows becomes.

The Invention will be described below with reference to an embodiment illustrated and explained.

It demonstrate:

1 : Measuring device in lateral view

2 : upper measuring rail in top view

3 : lower measuring rail in plan view

In the 1 a device for measuring the foot / leg area of a patient for the preparation of an orthosis is shown and generally with the reference numeral 1 Mistake. It consists of two support elements 2 and 3 for in guides 4 and 5 horizontally displaceable in the longitudinal direction measuring rails 6 and 7 ,

Connected are the vertically stacked support elements 2 and by means of a plate 8th in which bores are provided vertically one above the other at specific intervals, in accordance with the distance a to be set between the carrier elements 2 and 3 mounting screws 9 through aligned holes in the support element 2 be introduced.

By means of screws 10 is the plate 8th at the lower support element 3 fixed.

The upper measuring rail 6 is how out 2 emerges seen from above, U-shaped, with a U-leg 11 in the lead 4 is displaceable and has a scale, the horizontal distance of the calf of a patient from the rear applied, with the reference numeral 12 provided, at an angle of 90 ° horizontally from the thigh 11 angled, the two U-legs 11 and 13 indicates connecting web and the zero point of the measurement (location of the supporting point of the longitudinal arch support).

The U-thigh 13 is variable in length on the dock 12 arranged (only shown schematically), so that the calf width can be determined by adjusting the U-width. For this purpose is at the jetty 12 also a scale 14 intended.

The lower measuring rail 7 is also U-shaped, as shown 3 seen. She also points out that in the lead 5 slidable leg 11 a scale 10 on, the leg applied from behind to the heel 12 indicates the distance of the zero point (see above) from the back of the foot. Again, on the jetty 12 a scale provided.
