International Publication No. 2002/78999 JP 2010-30574 A JP-A-2005-58601

  However, the configurations of Patent Documents 1 and 2 are integrated with a vehicle seat and cannot be used after being removed from the vehicle (not assumed). Therefore, the subject cannot use the thrombus prevention device unless he / she gets on a vehicle on which this type of seat is mounted. Furthermore, the thrombus prevention device cannot be used outside of the vehicle (eg at home or at work). Moreover, in patent document 1, it is not described about what shape airbag is used. Patent Document 2 only describes the use of air pressure, and does not describe a specific configuration.

  Since the ankle joint exercise machine of patent document 3 is provided with the air bag only in the toe, the exercise | movement etc. which raise a heel cannot be performed effectively.

  The present invention has been made in view of the above circumstances, and its main purpose is to provide a thrombus prevention device that can be used in various places and that can be exercised inexpensively, in a small size, and with sufficient exercise. It is in.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to a first aspect of the present invention, a thrombus prevention device having the following configuration is provided in a thrombus prevention device for preventing a thrombus in the lower limbs by causing a subject to perform an exercise to raise a heel and a toe. That is, the thrombus prevention device includes a support base, a heel gas bag, a foot gas bag, a pump, and a control device. The support base is a box-shaped member that supports the weight of the subject's foot directly or indirectly and is portable, and has a heel opening and a foot tip opening. The gas bag for the heel is disposed inside the support base in a contracted state, and is inflated by inserting gas and extends vertically from the opening for the heel to push up the heel of one foot of the subject. In the bulging state, it has an elongated shape in the extending direction. The toe gas bag is disposed inside the support base in a contracted state, and is inflated by injecting gas and extends vertically from the toe opening so that the leg of one leg of the subject When the tip is pushed up and inflated, it has an elongated shape in the extending direction. The pump is disposed inside the support base, and inflates the bag gas bag and the foot bag gas bag. The said control apparatus is arrange | positioned inside the said support stand, is controlling the operation | movement of the said pump, and can control to inflate the said gas bag for a heel and the gas bag for a toe separately.

  Thereby, since the gas bag for the heel, the gas bag for the foot, the pump, and the control device are all arranged inside the portable support base, the thrombus prevention device can be arranged and used in various places. it can. Moreover, since the gas bag for the heel and the gas bag for the toe are elongated in the extending direction, the amount of gas necessary for inflating can be reduced as compared with the spherical gas bag. Therefore, even if the pump has a low discharge capacity, the subject can be allowed to exercise sufficiently, and the thrombus prevention device can be made inexpensive. Moreover, since the capacity | capacitance of a gas bag may be small, since the magnitude | size in the state which shrunk can be suppressed, the thrombus prevention apparatus can be reduced in size. Moreover, since the gas bag is arrange | positioned at both a heel and a foot tip, the exercise | movement which raises both a heel and a foot enough can be performed.

  The thrombus prevention device preferably has the following configuration. That is, the heel opening and the foot tip opening are formed on the upper surface of the support base, and the heel gas bag and the foot tip gas bag extend upward by being inflated. It is configured as follows. The support table also serves as a footrest, and the bag gas bag and the toe gas bag push up the subject's heel and toe directly or through the subject's footwear.

  Thereby, since a support stand serves as a footrest, compared with the structure which provides a footrest separately, a cheap and small thrombus prevention apparatus is realizable.

  The thrombus prevention device preferably has the following configuration. That is, this thrombus prevention device includes a footrest plate and a fulcrum portion. The footrest plate is a plate-like member that is disposed on the upper side of the support base and on which a subject places a foot. The fulcrum portion is disposed on the upper side of the support base and between the heel opening and the foot tip opening, and rotatably supports the footrest plate. The heel opening and the foot tip opening are formed on the upper surface of the support base, and the heel gas bag and the foot tip gas bag extend upward when inflated. It is configured. The footrest plate rotates so that the portion corresponding to the heel is raised and the portion corresponding to the foottip is lowered by being pressed by the heel gas bag extending upward. The footrest plate rotates so that a portion corresponding to the foottip is raised and a portion corresponding to the heel is lowered by being pressed by the footbag gas bag extending upward. .

  Thereby, since the fulcrum part and the footrest plate are arranged, even if the position where the foot is placed is displaced, the subject can be exercised sufficiently.

  In the thrombus prevention device, the control device can control any of the timing at which the pump inflates the heel gas bag and the toe gas bag, the inflating speed, and the pressure of the supplied gas. It is preferable.

  Thereby, it is possible to cause the subject to perform various movements and various load exercises using the thrombus prevention device.

  In the thrombus prevention device, the gas bag for the heel and the gas bag for the toes are foldable, and in an inflated state, the bag is substantially cylindrical and the height is at least twice the diameter. Is preferred.

  Thereby, since the gas bag in a contracted state can be further reduced by making the gas bag foldable, the thrombus prevention device can be further miniaturized. Moreover, the effect that a cheap pump can be employ | adopted by making the height of a gas bag more than twice a diameter, and the effect which suppresses the magnitude | size in a contracted state can be exhibited further.

  According to a second aspect of the present invention, there is provided footwear with a thrombus prevention device comprising the thrombus prevention device, a battery, and a foot insertion portion. The battery is disposed inside the support base and supplies power to the pump and the control device. The said foot insertion part is arrange | positioned above the said support stand, and is a part for a subject to put one leg. The heel opening and the foot opening are formed on the lower surface of the support base, and the heel gas bag and the foot gas bag are configured to extend downward when inflated. Has been.

  Thereby, by wearing the footwear with a thrombus prevention device, the thrombus prevention device can be used without placing a foot on a special device. Furthermore, the trouble of carrying the thrombus prevention device can be further reduced. Moreover, it can be applied to the use of creating a chance to raise a foot for a slack leg patient.

Side surface partial sectional drawing which shows the detailed shape and support structure of the gas bag for heels, and the gas bag for feet. The top view which shows the structure of the thrombus prevention apparatus which concerns on 2nd Embodiment, the side view when the gas bag for heels is inflated, and the side view when the gas bag for feet is inflated. The top view of the thrombus prevention footwear which concerns on 3rd Embodiment, the side view when the gas bag for heels is inflated, and the side view when the gas bag for toes is inflated.

  Next, embodiments of the present invention will be described with reference to the drawings. First, with reference to FIG.1 and FIG.2, the thrombus prevention apparatus 1 which concerns on 1st Embodiment is demonstrated. FIG. 1 is a plan view showing the configuration of the thrombus prevention device 1, a side view when the heel gas bag 21 is inflated, and a side view when the foot tip gas bag 22 is inflated. FIG. 2 is a side partial cross-sectional view showing the detailed shape and support structure of the bag gas bag 21 and the foot bag 22. In FIG. 1, the subject's feet and shoes 100 are indicated by chain lines.

  In the following, terms describing the positional relationship, size, shape, etc. include not only the case where the meaning of the term is correctly established, but also the case where the meaning of the term is substantially established (for example, The term “parallel” is intended to indicate not only a completely parallel state but also a substantially parallel state). In the following, “front” means the direction in which the subject's feet are facing, and the left side and the right side when facing the “front” are simply “left side”, “right side”, etc. Called. Further, the upper side and the lower side in the vertical direction are simply referred to as “upper side” and “lower side”.

  A thrombus prevention device 1 shown in FIG. 1 is a device for preventing a thrombus generated in a lower limb due to, for example, keeping the same posture for a long time. The thrombus prevention device 1 allows the subject (the person who is subject to the thrombus prevention device 1 to exercise, the user of the thrombus prevention device 1) to perform the exercise of raising the heel and the toes, thereby causing the blood flow in the lower limb By improving thrombosis, blood clots in the lower limbs are prevented. In addition, the thrombus prevention device 1 is small and configured to be easily carried, and the subject is carried to a place (for example, a vehicle, a home, a workplace, etc.) that often takes the same posture for a long time. Can be used.

  As shown in FIGS. 1 (a) and 1 (b), the thrombus prevention device 1 includes a support base 10, a heel gas bag 21, a foot tip gas bag 22, a pump 30, and a control device 40. Are provided as main components. The thrombus prevention device 1 is supplied with electric power via the power cable 51. This electric power is supplied to the pump 30, the control device 40, and the like.

  In the present embodiment, the gas bag 21 for the heel, the gas bag 22 for the toes, the pump 30 and the like are arranged in a pair on the left and right.

  The support base 10 is a box-shaped member (housing or housing) that accommodates the components constituting the thrombus prevention device 1. In this embodiment, the support base 10 has a rectangular parallelepiped shape, and the size in the vertical direction is the smallest among the sizes in the front-rear direction, the left-right direction, and the vertical direction. Moreover, unlike the patent document 1 etc., the support stand 10 is not embedded in other apparatuses, such as a sheet | seat, but is comprised so that it can carry. In the present specification, “portable” means a size that can be carried by a person who travels, travels to school, or commute without heavy load. Therefore, it is preferable that the size of the support base 10 in the front-rear direction and the left-right direction is 500 mm or less (more preferably 400 mm or less). The vertical size of the support base 10 is preferably 200 mm or less (more preferably 150 mm or less).

  In the present embodiment, the upper surface of the support base 10 is flat, and also serves as a footrest for the subject to place his feet (both feet). Thus, in the present embodiment, the support base 10 directly supports the weight of the subject's foot. In addition, in order to make it easy to understand the position where the subject puts his / her foot, a foot mark may be formed on the upper surface of the support base 10. Further, the support base 10 is not provided with a member (such as a band) for fixing the subject's foot.

  In addition, a pair of left and right heel openings 11 and a pair of left and right foot opening 12 are formed on the upper surface of the support base 10. The heel opening 11 has the same position in the left-right direction as the foot opening 12. The heel opening 11 is formed behind the foot opening 12. The bag gas bag 21 is accommodated in the lower part (inside) of the bag opening 11, and the bag gas bag 21 is inflated so that the bag gas bag 21 moves upward from the bag opening part 11. Extend. A foot bag 22 is accommodated below (inside) the foot opening 12, and the foot bag 22 is inflated so that the foot bag 22 is opened. 12 extends upward from each other.

  In addition, the support base 10 of this embodiment is an example, and a different shape and structure may be sufficient. For example, a support base for placing the left foot and a support base for placing the right foot may be separated. Further, the support base 10 may have a shape (for example, a disk shape) other than a rectangular parallelepiped shape. Moreover, in order to make it easy to put a foot | leg, the upper surface of the support stand 10 may incline forward (in other words, it inclines so that it may approach upwards as it approaches the front).

  The bag gas bag 21 is configured to be inflated by supplying air (may be another gas) from the pump 30 in a contracted (deflated) state (FIG. 1 ( b)). In addition, the bag gas bag 21 is configured to contract when the gas is discharged or sucked in the inflated state (FIG. 1C). The bag gas bag 21 is disposed inside the support base 10 in a contracted state. In addition, the bag gas bag 21 extends from the bag opening 11 to the outside (upward) of the support base 10 in the inflated state. With this configuration, the gas bag for heel 21 can cause the subject to perform an exercise of raising the heel by pushing up the heel of one foot of the subject. In particular, in the present embodiment, since the support base 10 also serves as a footrest, the bag gas bag 21 pushes up the subject's bag directly or via the shoe 100.

  Specifically, as shown in FIG. 2, the bag gas bag 21 is a bellows-like bag and is configured to be folded in a contracted state. Thereby, the volume of the gas bag 21 for bag in the contracted state can be made small. With this configuration, the size of the gas bag 21 for sputum in a contracted state can be suppressed, so that the thrombus prevention device can be reduced in size. In addition, a housing portion 23 for housing and supporting the bag gas bag 21 is provided inside the bag opening 11 of the support base 10. The accommodating portion 23 supports the bag gas bag 21 at a position higher than the bottom surface inside the support base 10. Further, a hole for inserting a hose 31 for supplying air to the bag gas bag 21 is formed in the housing portion 23.

  In the inflated state, the bag gas bag 21 has a substantially cylindrical shape. Specifically, it is preferable that the diameter of the bag 21 for bag is 20 mm or more and 40 mm or less. The vertical length of the bag gas bag 21 in a contracted state is preferably 5 mm or more and 15 mm or less, and the vertical length in the inflated state is preferably 50 mm or more and 150 mm or less. . Furthermore, the length in the up-down direction of the inflated state of the bag gas bag 21 is preferably 5 times or more, and preferably 10 times or more compared with the length in the up-down direction of the contracted state. Further preferred. As described above, the bag gas bag 21 of the present embodiment has the largest vertical size in the inflated state (that is, an elongated shape in the extending direction and the vertical direction). The bag gas bag 21 in a state where it is present is at least twice as high as its diameter. Thus, since the bag gas bag 21 has a shape elongated in the extending direction, the amount of gas necessary for inflating can be reduced as compared with a spherical gas bag. Therefore, even if it is a pump with low discharge capability, a subject can be made to perform sufficient exercise | movement.

  Since the foot bag 22 has the same shape and configuration as the heel gas bag 21, the arrangement of the foot bag 22 will be mainly described. As shown in FIG. 2, the foot tip gas bag 22 is stored in a storage portion 24 (same configuration as the storage portion 23) formed inside the foot opening 12. FIG. 2 shows the foot bag 22 inflated to some extent. Thus, in this embodiment, the foot bag 22 is arranged not only at the heel but also at a position corresponding to the foot. With this configuration, the toe gas bag 22 can cause the subject to perform an exercise of raising the toe by pushing up the toe of one foot of the subject. Moreover, in this embodiment, since the member which fixes a subject's leg | foot is not provided, even if it is a case where it is a case where it is pressed with strong force from the gas bag 21 for heels, or the gas bag 22 for a toe, the whole leg | foot is upward. Since it does not apply a large load to the ankle etc. just by moving to, it can be used easily.

  In addition, the gas bag 21 for heels and the gas bag 22 for a toe of this embodiment are examples, and may have a different shape, configuration, or arrangement. For example, the heel gas bag 21 and the toe gas bag 22 may have a foldable shape other than the bellows shape, as long as the shape is elongated in the extending direction (vertical direction) in the inflated state. It may have a shape that does not have a fold or the like and cannot be folded. Further, the heel gas bag 21 and the toe gas bag 22 may have different shapes.

  The pump 30 is disposed inside the support 10 and between the heel gas bag 21 and the foot gas bag 22. The pump 30 can take in and discharge (supply) air from the outside. The pump 30 has two discharge ports, and one discharge port is connected to the bag gas bag 21 (specifically, the lower end of the bag gas bag 21) via a hose 31. The other discharge port is connected to a foot bag 22 (specifically, the lower end of the foot bag 22) via a hose 32. With this configuration, the pump 30 can supply air to the bag gas bag 21 and the foot bag 22. As in the present embodiment, the thrombus prevention device 1 can be reduced in size by suppressing the lengths of the hose 31 and the hose 32 by disposing the pump 30 between the bag gas bag 21 and the foot bag 22.

  In addition, the pump 30, the hose 31, and the hose 32 of this embodiment are examples, and may have different shapes and configurations. For example, the pump 30 may be disposed at another position (the front end or the rear end of the support base 10). Further, the hose 31 and the hose 32 may be connected to other than the lower ends (for example, side surfaces) of the bag gas bag 21 and the foot bag 22. In addition, two pumps 30 each having one discharge port are arranged so that one pump 30 supplies air to the bag gas bag 21 and the other pump 30 supplies air to the foot bag 22. There may be. The pump 30 can be shared between the left and right sides. In this case, one pump 30 supplies air to the two bag gas bags 21 and the two toe gas bags 22. In this case, since the number of pumps 30 included in the thrombus prevention device 1 can be reduced to one, the thrombus prevention device 1 may be further reduced in size and cost.

  The control device 40 is disposed inside the support table 10 and at an end portion (specifically, a front end) of the support table 10 in the front-rear direction. The control device 40 can individually control the operations of the pair of left and right pumps 30. In the present embodiment, one control device 40 is provided in one thrombus prevention device 1, but a pair of control devices 40 may be provided on the left and right. In this case, the control device 40 may be disposed inside the pump 30.

  The control device 40 can individually control the timing at which the pump 30 inflates the bag gas bag 21 and the foot bag 22 (hereinafter, timing control). Specifically, the control device 40 can inflate the heel gas bag 21 and the toe gas bag 22 alternately. Thereby, since the subject can perform an exercise of alternately raising the toes and the heel, the subject's feet can be exercised efficiently. The term “alternate” means not only when the supply of air to the toe gas bag 22 is started after the heel gas bag 21 is completely contracted, but also before the heel gas bag 21 is completely contracted. The case where the supply of air to the gas bag 22 is started is also included.

  This timing control can also be synchronized by the pair of left and right heel gas bags 21 and the toe gas bags 22. In other words, the gas bag 21 for the right foot is inflated at the same time as the gas bag 21 for the right foot is inflated, and the gas bag 22 for the right foot is inflated at the same time as the gas bag 22 for the right foot is inflated. it can. Note that the timing may be reversed on the left and right. In other words, the gas bag 21 for the right foot is inflated at the same time as the gas bag 22 for the right foot and the gas bag 22 for the right foot is inflated and the gas bag 21 for the right foot is inflated at the same time. it can. Note that whether the timing control is synchronized or reversed on the left and right can be changed by the subject operating the operation unit (not shown) included in the thrombus prevention device 1.

  The timing control also includes controlling the time from inflating the heel gas bag 21 to inflating the toe gas bag 22. Furthermore, in this timing control, it is also possible to control the time interval for performing one set (or a plurality of sets) of exercises by inflating the toe gas bag 22 after inflating the heel gas bag 21. included. Thereby, for example, settings such as performing 5 sets of exercises every 10 minutes can be performed. These can also be set by the subject operating the operation unit. Thus, by setting the time interval, the subject can exercise without operating the thrombus prevention device 1 each time. Therefore, the time and effort for the subject to operate the thrombus prevention device 1 each time can be reduced. Even when the subject forgets to operate the thrombus prevention device 1, exercise using the thrombus prevention device 1 can be performed periodically.

  Moreover, the control apparatus 40 can control the speed | rate which inflates the gas bag 21 for heels, and the gas bag 22 for a toe (henceforth speed control). By performing this speed control, the intensity of the exercise performed by the subject can be adjusted. Therefore, it is possible to exercise with a degree according to the preference and muscle strength of the subject. The speed at which the heel gas bag 21 and the toe gas bag 22 are inflated can also be set by the subject operating the operation unit.

  Moreover, the control apparatus 40 can control the pressure of the gas supplied to the gas bag 21 for a heel and the gas bag 22 for a toe (henceforth, pressure control). By performing this pressure control, it is possible to adjust the force for pushing up the subject's heel and toes. Therefore, it is possible to exercise with a degree according to the preference and weight of the subject. The pressure of the gas supplied to the heel gas bag 21 and the toe gas bag 22 can also be set by the subject operating the operation unit.

  Next, a second embodiment will be described. FIG. 3 is a plan view showing the configuration of the thrombus prevention device 1 according to the second embodiment, a side view when the heel gas bag 21 is inflated, and a side view when the foot gas bag 22 is inflated. is there. In the following description of the second and third embodiments, members that are the same as or similar to those in the above-described embodiment may be given the same reference numerals in the drawings, and description thereof may be omitted.

  In the first embodiment, the upper surface of the support base 10 also serves as a footrest. On the other hand, in the second embodiment, the fulcrum portion 61 and the footrest plate 62 are arranged on the upper side of the support base 10. As shown in FIG. 3A, the fulcrum part 61 and the footrest plate 62 are provided in a pair of left and right, but the fulcrum part 61 and the footrest plate 62 having a large size in the left-right direction are used to The part 61 and the footrest plate 62 may be configured in common on the left and right (in other words, one thrombus prevention device may be configured to include one fulcrum part 61 and one footrest plate 62).

  Specifically, as shown in FIG. 3, the fulcrum portion 61 is disposed between the heel opening 11 and the toe opening 12. The fulcrum part 61 supports the footrest plate 62 in a rotatable manner. The footrest plate 62 is a plate-like member and is rotatably supported by the fulcrum portion 61 in the vicinity of the center. The size of the footrest plate 62 in the longitudinal direction (front-rear direction) is arbitrary, but is preferably longer than the size of a general shoe. Further, the upper surface of the footrest plate 62 is a portion for the subject to place his feet. Accordingly, the support base 10 of the second embodiment supports the weight of the subject's foot via the fulcrum part 61 and the footrest plate 62 (that is, indirectly). Also in the second embodiment, no member for fixing the subject's foot is provided on the support base 10 and the footrest plate 62 or the like.

  When the pump 30 supplies air to the bag gas bag 21 and the bag gas bag 21 is inflated, the bag gas bag 21 extends upward (extension direction) and the rear part of the footrest plate 62 (to the bag). The corresponding part) is pushed up (FIG. 3B). Since the footrest plate 62 is rotatably supported by the fulcrum portion 61, at the same time, the front portion of the footrest plate 62 (portion corresponding to the tip of the foot) rotates downward. On the contrary, when the pump 30 supplies air to the toe gas bag 22 and the toe gas bag 22 is inflated, the toe gas bag 22 extends upward (extension direction) and the footrest plate The front part of 62 is pushed up, and thereby the rear part of the footrest plate 62 rotates downward (FIG. 3C). Therefore, also in the second embodiment, similarly to the first embodiment, it is possible to cause the subject to perform an exercise of raising the subject's heel and toes.

  By providing the fulcrum part 61 and the footrest plate 62 as in the second embodiment, even if the position where the subject's foot is placed is shifted, the subject can be exercised sufficiently.

  Next, a third embodiment will be described. FIG. 4 is a plan view of a thrombus prevention footwear 2 (footwear with a thrombus prevention device) according to the third embodiment, a side view when the gas bag 21 for heels is inflated, and a case where the gas bag 22 for the toes is inflated. FIG.

  A thrombus prevention footwear 2 according to the third embodiment includes the above-described thrombus prevention device 1 and a foot insertion portion 71 disposed on the upper side of the thrombus prevention device 1. The foot insertion part 71 is a part for the subject to put one foot. The foot insertion portion 71 of the third embodiment has a shoe shape, but may have a sandal shape or a slipper shape. On the lower surface of the foot insertion portion 71 (a sole portion of a general shoe), the thrombus prevention device 1 is disposed. Therefore, in the third embodiment, the support 10 of the thrombus prevention device 1 supports the weight of the subject's foot via the foot insertion portion 71 (that is, indirectly).

  The thrombus prevention device 1 of the third embodiment is different in the vertical direction from the thrombus prevention device 1 of the first and second embodiments. That is, in the third embodiment, the heel opening 11 and the foot opening 12 are formed on the lower surface instead of the upper surface. In the third embodiment, power is not supplied from the outside via the power cable 51, but power is supplied to the pump 30 and the control device 40 by the battery 52 disposed inside the support 10 of the thrombus prevention device 1. Is supplied. Moreover, since the thrombus prevention footwear 2 of 3rd Embodiment is footwear, the structure of right and left is isolate | separated. That is, all members including the control device 40 are provided in a pair of left and right.

  By attaching the thrombus prevention footwear 2, unlike the first and second embodiments, the thrombus prevention device 1 can be used without placing a foot on a special device. It is assumed that the thrombus prevention device 1 of the thrombus prevention footwear 2 is basically used in a seated state. Accordingly, a sensor for detecting that the subject is standing is provided, and when it is detected that the subject is standing, the thrombus prevention device 1 can be invalidated. The configuration of the sensor for detecting that the subject is standing is arbitrary. For example, a pressure sensor is provided in the thrombus prevention device 1, and it is determined that the subject is standing when the applied pressure is equal to or higher than a predetermined value. be able to.

  The thrombus prevention footwear 2 can also be applied to the use of creating a chance to raise a foot during walking for a patient with a short leg. A freezing leg patient can walk, but it may be difficult to raise the leg at the start of walking. Therefore, the leg of the subject can be forcibly raised by inflating only the heel gas bag 21 (or both the heel gas bag 21 and the toe gas bag 22) at the start of walking. In addition, when using as this use, it is necessary to turn off the function which invalidates the thrombus prevention device 1 when the subject stands.

Moreover, since the member which fixes a subject's leg | foot is not provided, even if it is a case where it is a case where it is pressed with strong force from the gas bag 21 for a heel, or the gas bag 22 for a toe, the whole leg | foot only moves upwards. Since a large load is not applied to the ankle or the like, it can be used easily.

  The thrombus prevention device 1 according to the second embodiment further includes a footrest plate 62 and a fulcrum portion 61. The footrest plate 62 is disposed on the upper side of the support base 10 and is a plate-like member for the subject to place his feet. The fulcrum part 61 is disposed above the support base 10 and between the heel opening part 11 and the foot tip opening part 12, and supports the footrest plate 62 in a rotatable manner. The support 10 and the footrest plate 62 are not provided with a member for fixing the subject's foot. The heel opening 11 and the toe opening 12 are formed on the upper surface of the support base 10, and the heel gas bag 21 and the toe gas bag 22 are expanded so as to extend upward. It is configured. When the footrest plate 62 is pressed by the heel gas bag 21 extending upward, the footrest plate 62 rotates so that the portion corresponding to the heel is raised and the portion corresponding to the foottip is lowered. The footrest plate 62 is pivoted so that the portion corresponding to the foot tip is raised and the portion corresponding to the heel is lowered by being pressed by the foot bag 22 extending upward. .

  Thereby, since the fulcrum part 61 and the footrest plate 62 are arranged, even if the position where the foot is placed is shifted, the subject can be exercised sufficiently. Moreover, since the member which fixes a subject's leg | foot is not provided, it can be used casually.

  The thrombus prevention footwear 2 according to the third embodiment includes the thrombus prevention device 1, a battery 52, and a foot insertion part 71. The battery 52 is disposed inside the support base 10 and supplies power to the pump 30 and the control device 40. The foot insertion portion 71 is disposed on the upper side of the support base 10 and is a portion for the subject to put one foot. The heel opening 11 and the toe opening 12 are formed on the lower surface of the support base 10, and the heel gas bag 21 and the toe gas bag 22 are configured to extend downward when inflated. Has been.

  Thereby, the thrombus prevention device 1 can be used by putting the thrombus prevention footwear 2 on without putting a foot on a special device. Furthermore, the trouble of carrying the thrombus prevention device 1 can be further reduced. Moreover, it can be applied to the use of creating a chance to raise a foot for a slack leg patient.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  In the said embodiment, although the gas bag 21 for heels and the gas bag 22 for a foot are comprised from one bag, you may be comprised from the several gas bag. For example, a substantially cylindrical gas bag having a smaller diameter may be arranged side by side.
