Mobile device, especially for use by thromboses

The present invention relates

of TT womboses during long sitting.

Every year, more people die of TB-related accidents and their consequences than civilian casualties due to accidents or downhills

long-distance travel, particularly affecting older people, who are more susceptible to vascular and muscular tissue disorders as well as kaitiiormlmonale diseases.

Thrombosis is caused, for example, by stagnation of the venous blood fluid, with premature dosing and (often age-related) insufficiency of the venous valve system in varicose veins. Thrombosis is particularly required in this case, especially due to long periods of sitting (eg with guided flights). After long flights, such a thrombus is repeatedly flushed into the lungs via the heart, where it leads to a more or less severe pulmonary embolism 7% of all cases go to death, but in any case requires a hospitalization for thrombolysis

The previously known methods for the prophylaxis of thrombosis during long sitting are either hardly practicable or inadequate. The Empfehhing, before beginning a A flight of more than four hours to wear support stockings, is out of touch with reality and an effect is hardly given.

Ice Around the plane (usually with 400 passengers in the transcontinental air traffic) is hardly possible for safety reasons. In addition, the passengers are usually very cramped with long-term bent knees, without the possibility of

To be able to stretch legs.

The drugs currently available on the market must be injected to prevent thrombosis, which prevents many people from using such drugs, since an independent spraying before a flight is not feasible for many people. In addition, the previously known drugs in the effect of controversial, The present invention is based on the object, the o.g. Overcome problems that occur during long periods of sitting effectively and without much effort.

This object is achieved by a mobile device, unifassend at least one flexible sleeve, in particular for attachment to the ünterschen- kei a user, which cuff at least two separate

Chambers for introducing medium further comprising at least one pump for introducing the medium into the chambers, the Manschetie, wherein the chambers of the cuff are alternately filled with medium and emptied again,

With the device according to the invention, which can be taken anywhere by its design by an operator with bin, the physiological muscle pumping effect can be imitated by a rhythmic compression and decompression of a lower leg cuff. The device according to the invention is intended in particular for air travelers. The device according to the invention is of course also for other situations that require a long sitting (eg train rides, Bosfahrte »etc.). suitable. The device according to the invention is also suitable for clinical use (eg in the case of postoperative thrombosis prophylaxis, coma patients, etc.).

Advantageously, the erSndüngsgemäße device on two cuffs, which are preferably identical, which are attached to each lower leg of a user. In this way, both lower legs can be stimulated, which increases protection against thrombosis.

In a particularly preferred embodiment of the device according to the invention, the chambers of the cuff are not simultaneously filled, but alternately filled with medium or emptied. By this mutual actuation of the at least two chambers for filling or emptying the same is prevented that the Haüt is always pressed in the same places. In addition, this measure makes an even more effective massage effect and even more effective imitation of the physiological pumpkin pumping effect possible.

The medium could theoretically be liquids or gels.

It is preferred, however, that the medium is a gaseous medium, in particular air, since working with air is much less complicated and easier than would be the case with liquids or gels which would have to be constantly felt.

In general, the flexible sleeve of the device according to the invention has two separate chambers for the introduction of medium.

It is conceivable that the at least two chambers of the flexible sleeve are filled with medium by a single pump, wherein a valve would serve for the mutual supply of the chambers with medium, in particular air. However, it is preferred that a pump for introducing the medi ums is provided for each chamber Each of these pumps is designed to be identical in the rule. The provision of a respective pump for each of the existing chambers brings, inter alia, the advantage that in the event that a pump fails, a total failure of the entire device is avoided. The pumps can, for example, be supplied with electrical power, in particular direct current, by means of an iron battery and / or a battery and / or the electrical system of a means of transport. In a further development of the device according to the invention, this can also be connected to a vehicle electrical system (eg to the electrical system of an aircraft, car, etc.) and thus be supplied with electric current.

Advantageously, the device according to the invention has a control which in particular controls the pumping intervals, the pressure in the chambers and / or the change from one chamber to the other chamber when introducing medium, wherein preferably the individual parameters can be adjusted by the user. For example, with such a control it is possible to automatically switch over to the next / other chamber after each use of a chamber, for example by automatically activating the pump connected to this chamber. As a result, a fully automatic operation of erfmdongsgernäßen device is made possible, so that the device for a long period of time (many hours to days) can be operated without the user would have to act for this.

In general, the chambers for introducing medium with the at least one pump via a respective hose are connected, wherein the compounds are preferably solvable via cuff-near plug-in couplings. Such quick connections are primarily used to make in the panic furrow, especially in stationary pump unit (eg in public transport) a separation without having to put down the cuff. In a preferred embodiment of the device according to the invention, the abovementioned hoses have a permanently opened medium outlet, in particular an air outlet, which is preferably dimensioned so that the respective chamber is passively blocked by outflow of the container after a bumping operation within a period of approximately 20 to 30 seconds Medium, in particular air is released and thus überfuhrt from an inflated to a more or less empty state. In the case of air, therefore, the cuff loses during the inflation of eiser chamber in this chamber again Luit, The influx, which through the pump is arranged with the air outlet so that the compression function is ensured over the selected period. The compression pressure is preferably controlled exclusively on the Pumperdaafeeit, since the pumps can produce a very high pressure and must press against the end of the pumping time against an ever-increasing resistance of the sleeve. The maximum values are defined by material properties and pump power.

Advantageously, the at least one pump is automatically switched off at a specified maximum pressure in a chamber. This prevents overloading of the at least one pump,

The chamber-like structure of the flexible cuff prevents a feeling of pain and irritation of the skin of the lower leg, which again and again occurs in too short a time.

Advantageously, the cuff is made of flexible material, especially rubber. The flexible design of the cuff allows both, a simple attachment of the same to a lower leg as well as a quick and easy collapsing / rolling to the space requirement of the cuff for transport to a minimum to reduce. The rolled / folded cuff may e.g. easily transported in a jacket pocket,

Preferably, the sleeve is in a, in particular strain-resistant sheath, such as a nylon bag introduced nylon, for example, has the advantage that it is washable and very stretch-resistant. Advantageously, the cuff can be fastened to a human limb, in particular a lower leg, via a quick connection device, in particular by means of Velcro fasteners, zippers, hook connection, etc., wherein the quick connection device is preferably attached to the flexible covering. By providing a Schnellverbindseinriehtung the cuff can be easily and quickly attached, for example, to a lower leg and released from it again. In the rain! The cuff has a substantially rectangular shape and preferably a width of about 20 to 40 cm, preferably about 30 cm, and a length of about, 60 to 80 cm, preferably 70 ran on. In the case of the sleeve being surrounded by a flexible sheath (see above), the specified length and width values correspond to those of the flexible sheath.

Further features of the invention will become apparent from the following description of preferred exemplary embodiments of the invention in conjunction with the drawings and the dependent claims. Here, the individual features can be realized alone or in combination with each other ».

In the drawings show:

Fig. 2; a schematic representation of another embodiment of an inventive dungsgemaßen device.

Fig. 1 shows a mobile device 1 for the prevention of thrombosis during prolonged sitting. The device 1 comprises a flexible cuff 2 for attachment to the lower leg of a user. The cuff 2, which is shown transparent in the present drawing from Ubersichtsgunden is in the illustrated embodiment in the form of a rubber jacket before. In the cuff 2 (ie in the rubber jacket) are two separate chambers 3, 4. The chamber 3 has one above the other and parallel arranged slide-like structures 5, which are connected to each other via narrower connecting portions 6. Also, the second chamber 4 (shown in phantom) has such tubular structures 7 on soft also via connecting portions 8 are interconnected. The cuff 2 is surrounded by a wrapping bag 9 made of nylon. The wrapping bag 9 has Velcro strips on its narrow sides, wherein on one side a strip 10 of flexible barbs is arranged and on the other side a strip 1 1 with Sehtau- fen arranged which together form a Velcro connection. The tubular structures 5 and 7 of the combs 3 and 4 are arranged such that after each tube 5 of the first chamber 3, a tube 7 of the second chamber 4, etc. is arranged. This results in a uniform distribution of the individual hose-like structures 5 and 7 of the respective chamber 3 and 4 respectively.

Both in the cuff 2 and in the enveloping bag 9 are each two recesses 22 for passing through each of a hose 12 and 13 are arranged The hose 12 is directly connected to the chamber 3 and forms a quasi-continuation of this chamber 3. The hose 13 is with Connected to the chamber 4, and forms a continuation of this chamber. The hose 12 is connected to a pump 14, the hose 13 is connected to a pump 15, which pumps 14, 15 can pump air into the chambers 3 and 4, respectively. The hoses 12 and 13 each have a Steckkupplurtg 16 so that a quick separation between the respective pump and the respective chamber is possible. In this way, a quick separation of the sleeve 2 from the pumps 14 and 15 can be made in the panic case. The pumps 14 and 15 are powered by a battery 17 with DC. Via a control element 18, which is connected to the pumps 14 and 15 and to the battery 17, the pumping interval, the cuff pressure and the order of the pumping operation are controlled. The control element 18, the battery 17 and the pumps 14 and 15 are housed in a common housing 19, which can be worn for example on the belt or in a bag by a user. Both the pumps 14, 15 and the battery 17 and the control element 18 are shown here only schematically as a box

The pumps 14 and 15 alternately pump air into the chambers 3 and 4, respectively. In the present example, the apparatus 1 is operated as follows: First, the pump 14 pumps air into the chamber 3 via the hose 12 for about five seconds Phase is the chamber 4 in the slack (empty) state. Subsequently, the chamber 3 is passively emptied by air over a recess 20 in the tube 12 flows out the emptying phase lasts about 20 to 30 seconds, until the chamber 3 is in an empty state. As a result, air is pumped into the chamber 4 by the pump 15 via the hose 13. Again, the filling process takes about five seconds. As a result, the chamber 4 is passively freed of air by the air from the chamber 4 via an opening 21 in the hose 13 flows out. Subsequently, the pump Zyidus begins from the front. All time intervals can be set either at the factory or by a user via the rule element 18. If the device 1 is no longer required, the user can switch off the device, whereby the leizmemdzte chamber is passively emptied and the Velcro fastener formed from the elements »10 and 11 is released.

Any concurrent injuries of a user, e.g. open wounds, etc. are not contraindications to the use of the cuff. They need only be slipped and covered. The device 1 not only has a prophylactic effect, but can also be used by healthy vascular users, since it also prevents the occurrence of swollen legs and ankles due to the relative stasis of the blood at constant arterial pressure in addition to thrombosis prophylaxis. Besides, the massage effect is pleasant.

The envelope bag 9 has a length of approx. 70 cm and a width of approx. 30 cm. In addition to a Velcro, for example, a. Zipper can be used

Certain elements of the device t, in particular the cuff 2 or the GeMuse 19 and also a storage pocket of the overall device (not shown here) can act as an advertising medium. The battery pump control unit may for example be housed in a portable bag, which may be configured so that it Einschieblaschfeen and storage compartment for eg private information, medicines, etc. has. FIG. 2 shows a schematic representation of a further development of a device 100 according to the invention, which looks like the one shown in FIG. illustrated device 1 only differs in that two identical cuffs 2a, 2h are present. The housing 19 and the elements therein pumps 14, 15, battery 17 and control element 18 are shown in the here. Device 100 identical present. The pumps 14 and 15 provide both cuffs 2a, 2b, respectively, by leading from the pump 14 a tube 12a into the chamber 3 of the cuff 2a and introducing a tube 12b into the chamber 3 of the cuff 2b. From the pump 15, a tube 13a leads into the chamber 4 of the cuff 2a and a tube 13b into the chamber 4 of the cuff 2b. The two hoses, which lead to a cuff, are connected with each other in the form of a double hose for the sake of better handleability. In addition, the individual elements function analogously to the elements of the device 1 of FIG. 1. Overall, it can be said that This mobile device is ideal for use in long journeys to prevent thrombosis. The device is quick and easy to use, as well as quick and easy to stow. Through the chambers 3, 4, which branch uniformly in the interior of the sleeve 2, it is possible that alternately different areas of the sleeve 2 are pressurized. Thus, different areas, for example, of a lower leg are alternately compressed and decompressed again.
