Abstract

The patients feet are fastened to pedals (1) which are driven by an electric motor (2) via a belt (3). The feet are made to perform a pedalling motion. The calves of the patients legs are supported by loops of cord padded with many small rollers. The loops are supported by a centre post (8) with attachments (13) which may slide in slits (14). Their outer ends are supported by a rubber band (12) passing over rollers (11) on the top of posts (9) standing outside the patients legs. The posts are supported on a framework of horizontal members.

Description

Musculoskeletal system for the lower extremities

passive movement.

Preventing the development of thrombosis after an operation in bedridden patients in the leg and pelvic veins is through passive movement of the legs possible; and in contrast to the drug-based thrombosis propophyls layperson is completely harmless.

In the recovery phase after fractures of the spine, the pelvis and the lower extremities, when the affected body parts are not yet loaded the legs must also be moved passively.

A regular, passive movement of the legs is after paraplegia necessary to reduce the shrinkage of the muscles or the stiffening of the joints impede.

In isotope lymphography (representation of the leg and pelvic veins ) is for the regular removal of the marked particles from the injection site constant movement of the legs is required.

In these cases, the passive movement of the legs, mostly temporal only very limited, carried out by P; laying staff.

There are already medical devices for the passive movement of heat or the legs got. An apparatus described for the passive movement of the legs is of such cumbersome construction that it is now regarded as completely out of date must be (DT-PS 226709). Two other apparatus are only available with one "exercise lever" "stripped out and are not suitable for passive movement of the legs.

(DT-PS 192725 and DT-PS 459741).

The invention is based on the object of the lower extremities to move passively by a suitable direction.

This task is solved by the fact that one that can be set up in every bed with a guide fork for the lower legs provided by an electric motor is driven.

The advantages achieved by the invention are that the previously passive movement of the legs performed by nurses; by one with an electric motor Powered treadmill replaces this. This results in a time-unlimited possibility the passive leg movement in all of the above-mentioned clinical pictures independently from the nursing staff.

Figure 1 shows the device set up in the bed.

The pedals (are driven by the electric motor 2 through the V-belt X. The number of revolutions of the pedals can be adjusted by the resistance upstream of the rotor 10-60 rev / nin. can be set. The pedals are padded for fixing the foot Heel supports and provided with leather straps 18. The Ilhe of the Trettwerkes 6 together with the motor 2 can be adjusted with the plunger screw.

the guide fork 7 can be between the rails 8 and 9 on and starting to move freely. The fixation or the guide dew guide fork 7 is on the Rail through the 2 guide rings 10, on the rail 8 through the pin 13, the running in the side slot 14 of the rail, reached. The guide forks are Connected to one another via the rollers 11 with the rubber band 12 and thereby upwards drawn.

The feet of the lying patient are strapped to the pedals, the lower legs lying in the guide forks 7. The one on the guide fork Threaded balls 7 cause the IT thighs to slide smoothly in the tabs, massage the lower leg muscles and prevent them from kinking of the legs in numb or exhausted patients. By the upward Train the rubber band 12 is the guide fork or its ball padding on the Lower legs and thus develop their support and massage effect.

The guide forks can be screwed depending on the length of the lower leg 15 can be adjusted in the horizontal plane.

Fig. 2. shows the device as it is used for diagnostic purposes is used in radiology. The electric motor-driven pedal mechanism is delimited with a couch, 16, the backrest 17 is adjustable. The guide forks, if necessary, they can also be installed.

Claims (3)

Musculoskeletal system for the lower extremities for passive movement. Claims 1. Device for passive movement of the lower extremities characterized in that a treadmill 5, on the pedals of which the feet of a lying Patients can be buckled up by an electric motor (2) with adjustable The number of revolutions is driven in the unit of time; and that the device in Can be placed in any (sick) bed. 2. Device according to claim 1, characterized in that 2 U-shaped, stirring forks padded with roller balls 7, which are held by a rubber band) over rollers are connected to each other in such a way that they pass through the liter legs while moving Pedals that support the lower legs and the lower leg muscles at the same time Massage with even pressure. 3. Apparatus according to claim 1 and 2, characterized in that when used outside of the hospital bed, e.g. in X-ray diagnostics, can be bordered with a lounger 16. The device is particularly suitable for: Postoperative thrombosis prophylaxis in the sickbed. - Passive movement exercises after bone fractures in the opposite phase in the sickbed. - Passive movement exercises for paraplegics and others Diseases of the lower extremities. - Standardization of contrast agent absorption in isotope lymphography through the controlled, passive movement.
