COMP-RESSIVE HOSE.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed February 12, 1908. Serial No. 415,557. i

To all whom it may concern:

Be it known that I, WVILHELM JULIUS TEUFEL, a subject of the Emperor of Germany, residing at Stuttgart, Germany, have invented certain new and useful- Improvements in Compressive Hose, of which the following is a full, clear, and exact specification.

This invention relates to hose exercising at different places as desired a different elastic pressure upon foot and limb. This result is obtained by using at the placesin question in the hose more or less elastic rubber threads or by inserting the rubber threads farther apart from each other at places where only a slight compressive 'action is desired.

At places upon the limb or foot where no required, the rubber thread can also be replaced by any kind of elastic worsted or woven material etc. By such an arrangement it is possible to prevent the edges of the compressive hose from cutting into the soft flesh of the patient and to cause disturbances in the blood circulation and that sore or bruised places and healthy parts of the limb or footv may be subjected to different pressures so that any bad effects resulting from subjecting these places, differing in their power of resistance, to an equal pressure, which would cause interruptions in the circulation of the blood, are prevented.

Heretofore only one kind of rubber. threads has been used in the manufacture ofcompressive hose, so that every part of the body surrounded by the hose was subjected to an equal elastic pressure.

In practice it has been shown, that by the use of such a compressive hose, made of threads of equal strength the following undesirable results were produced:

1. The edges of the compressive hose being of the same material as the body of the hose, cut into the flesh of the patient which caused interruptions of the circulation of the blood which should especially be avoided in the treatment of varicose limbs. Furthermore it caused the cutting of the edge of the hose into the flesh with consequent sore, spots, and besides was very trying to the patient. These inconveniences are done away with by the arrangement of suitable broad bands atthe upper and lower edges of the hose through which the compressive action of the hose is considerably weakened or wholly neutralized and by the intermission of rubber threads of lighter grade toward the ends of the hose so as to prevent a cutting of the edges into the flesh of the limb or foot and the complications caused thereby.

2. The sore as'well as the healthy parts of the foot or limb were heretofore subjected to an equal degree of pressure which 'is entirely impracticable as the healthy parts in which the muscles, the flesh and the blood vessels are in good condition offer a greater resistance 'to the pressure of the rubber hose than the diseased parts with their soft flabby muscles and flesh in which the blood vessels are already enlarged and show a,

knotty growth. If for instance the calf of a limb is diseased and the part beneath thereof is healthy and both receive the same pressure a more or less strong interruptionin the blood circulation will be caused in the part adjacent to the healthy part, the

pressure of which will react upon the diseased calf of the limb so that the pressure in the blood vessels of this part will be increased and more harmthan good will be done. It is therefore entirely wrong to subject the diseased and the healthy parts to an equal pressure and it is evident that the healthy parts should be subjected to less pressure than the diseased. To meet this requirement the compressive hose must be made so as to exercise a stronger pressure upon the diseased parts than upon the healthy parts of the limb or foot.

compressive hose answering this purpose is manufactured by inserting at the places where a slight elastic pressure is required, rubber threads of greater elasticity or, if rubber threads of equal elasticity are used, by inserting the same at larger intervals. In special cases the rubber threads may at places also be entirely dispensed with and be substituted by suitable elastic worsted or woven material of sufficient strength. w

Besides the above enumerated advantages the hose forming the object of the present invention can be manufactured in any suitable length and color so that it can not be distinguished from any ordinary hose. Furthermore the wearing of two pairs of stockings; the stocking and the incbnveniences caused thereby are avoided which is of special advantage for corpulent or very sick persons,

and above all the costs of manufacture are cons derably reduced, as a compressive hose according to the present invention may be manufactured much cheaper than a hose made entirely of expensive rubber.

Compressive hose reaching above the knee 1 as manufactured heretofore show the disadvantage that besides the difiiculty in putting on and removing them they easily form folds or creases in the bend of the knee especially when the limb is frequently bent as in sitting position, as the rubber hose is naturally thicker at the bend than at other .parts and this is very often the cause of a very disagreeable soreness at the said bend. This dlsadvantage is successfully overcome by the object of the present invention in heated and the entire limb is influenced m a wholesome manner.

In the accompanying drawings forming part of this specification: The drawing represents a combination hose of rubber and worsted or woven material.

The drawing shows a combination hose in which a compressive hose is combined with an ordinary hose. The calf of the leg is considered to be the diseased part and correspondingly the hose a at this part is made of rubber threads of ordinary grade, above and below said hose a strips b are provided made of rubber threads of lighter grade which may be called transition-strips to which at the lower end is attached the foot piece 0 of ordinary worsted material and in the same way the top part of ordinary hose is attached to the edge oi the upper transitions'trip. The strips b may also be omitted and the arrangement of the parts of difi'erent compressive material may be varied at will according to occasion as the necessity may require.

Having thus described my invention what I claimis:v

Seamless compressive hose embodying in a continuously woven tubular single element a foot piece of worsted material, a band of rubber threads at the calf portion, to exercise increased pressure onthe diseased part, a band of lighter threads of rubber between the same and the foot piece, a band of like threads above the calf piece and a portion of worsted material ,above the last named band.

In testimony whereof I affix my signature.
