Footrest for prevention of disorders of venous blood flow: of varicose vein and deep vein thrombosis of feet
The invention concerns medicine and hygiene areas. Footrest for prevention of disorders of venous blood flow (of varicose veins and deep vein thrombosis of feet), comprising: the support (supports) of feet, which allows to do simple prophylactic motions by feet in ankle joint and also allows to regulate the amplitude of described motions of feet; a unit of sound-alarm; an alarm-lamp; the communication interface; a sensors, which allows to measure amplitude, frequency and quantity of motions of the feet in ankle joint; a device of control, which capable to compare amplitude, frequency and quantity of motions of the feet in ankle joint, executed by user in certain interval of time, with preset parameters (for which there is no stagnation of blood and there is no creation of blood clots in veins of feet) and capable (if measured data are not conforms to preset parameters) activate the unit sound-alarm and an alarm-lamp for reminding the user of necessity of renewal of prophylactic exercises of feet or capable transmit the alarm message through communication interface.

2. TECHNICAL LEVELIt is known that long confining job leads to fatigue of feet. Therefore desks long ago manufactured with supports for feet in the form of a crossbar mounted between a legs or a lateral stands of a desks. It gave the chance to change periodically position of feet, laying them on crossbar to making simple motions by feet in ankle joint.
The “computerization” of society has sharply increased percent of the population of globe which spends the most part of time sitting at a table—not only in the course of works, but also on rest (at computer games or in a network the Internet). The problem of confining job amplified by a sedentary way of life. Established that long confining job conduce to occurrence of infringements of venous blood circulation in shins of feet that can lead, at first, to varicose veins, chronic venous insufficiency and then to very dangerous thrombosis (or thrombophlebitis) of veins of feet.
The given facts were an incitement to inventing of various footrests, exercisers, massage apparatus for feet which would usable for decrease of fatigue, increase of muscular activity of feet, execution of preventive exercises. Supports for feet and exercisers of feet, in particular, are described in following patents and patent applications:
-
- patent application RUSSIA 99103559/12 (3 Feb. 1999, A63B23/04);
- the patent of the U.S. Pat. No. 7,081,099 (25 Jul. 2006, A61H15/00);
- the patent of the U.S. Pat. No. 7,239,839 (13 Nov. 2007, A47C7/50).
Among analogues the closest to the invention is the device described in item 1 of the claims of the patent application RUSSIA No. 2005141536/12. The device represents a platform for feet. That platform can oscillate in cross-direction of longitudinal axis of a platform, and degree of an bias of a platform can be regulated with use of various adjusting mechanisms. Such device allows to do simple motions by feet in ankle joint. Motions must be doing with wide amplitude. Motions are simple, but effective enough for prevention of varicose vein, phlebitis and thrombophlebitis.
The described device has a drawback limiting its efficiency as device of prophylaxis. Apparatus may be used only in special time assigned for this purpose (for example, in centre of physical culture or in exercise room), but not in the course of sedentary works. Certainly, people having very strong motivation to prevent diseases of veins, can regularly use such device in the course of sedentary works. However, for all others it is not really, because, work or other employment will strongly distract them from of prophylactic exercises. In addition, the design of the device is enough complex and resource.
3. DISCLOSING OF THE INVENTIONThe purpose of the invention:
-
- expansion of conditions, in which we can effectively use of the device as preventive means from diseases of veins of feet;
- enhancement of preventive efficiency of the device;
- simplification of the mechanical complexity of device;
- reduction of cost price of device.
Purpose achievement warranted by creation of possibility of effective exploitation of the device in working time or in time of other employment to which the person gives a great attention.
For this purposes:
-
- a/ the platform for feet is excluded from apparatus. Cross-bar (without platform) allows to do simple motions by feet in ankle joint. The height of installation of a cross-bar defines possible amplitude of motions of feet and can be regulated for the size of a sole of feet of the concrete person;
- b/ the footrest must be equipped with the sensors providing definition of the fact that user does motions by feet (by a soles) in ankle joint with the big amplitude. The sensors are allows to measure frequency and quantity of such motions. Also, in the footrest there are control device, sound-alarm and alarm-lamp. The control device is capable to compare frequency and quantity of such motions of the feet executed by the person during certain intervals of time, with preset boundary conditions at which there is no stagnation of blood and there is no creation of blood clots in veins of feet. If parameters, defined by sensors, is not conforms to boundary conditions, the control device actuates sound-alarm and alarm-lamp for reminding the user of necessity of renewal of prophylactic exercises. If in hardware of device there is the communication interface he can transmits the information from control device into the computer or into devices of remote monitoring, for example, to management of the equipment.
The drawings are represents some of variants of realizations of the invention:
on FIG. 1—one of the many variants of mechanical design of the device;
on FIG. 2—one of the variants of the schemes of electric functional.
On
Are possible:
a/ other variants of mechanical design of footrest;
b/ other types of sensors of the motions by feet in ankle joint,
On
Other variants of connection and teamwork of elements of the scheme of a device are possible.
Claims
1. Footrest for prevention of disorders of venous blood flow, of varicose of vein and of thrombophlebitis containing the basis and support of feet which allows to make simple motions by feet in ankle joint and to regulate amplitude of described motions of feet by height of installation of a support concerning the support basis, but DIFFERS FROM THE EARLIER ONES because the footrest includes:
- the elements of sound-alarm, alarm-lamp and (or) by the computer interface;
- the sensors which can to define of the fact that user makes motions of feet in ankle with the needed amplitude and which can to supervise frequency and quantity of such motions;
- the control device, capable to compare frequency and quantity of such motions of the feet which executed by the user during certain intervals of time, with preset boundary conditions at which there is no stagnation of blood and there is no creation of blood clots in veins of feet. If measured parameters is not conforms to boundary conditions, the control device actuates sound-alarm and alarm-lamp, or downloads the information onto the screen of monitor of the computer (or onto the TV screen) for reminding the user of necessity of renewal of prophylactic exercises or transmits signals onto remote terminal of monitoring of muscular activity of feet of the user.
