Description

Automatic ankle pump device based on biosignals {AUTOMATIC ANKLE PUMP APPARATUS BASED ON BIOSIGNAL}

The present invention is an ankle pump device comprising: a pulse detection unit for detecting and transmitting a user's pulse; A base plate seated on the ground, a holding member disposed behind the upper surface of the base plate and allowing feet to be inserted at a predetermined height from the ground, an aligning member for bringing together the feet inserted inside the holding member, and a standing member for standing up the toes. a leg support unit including a member and maintaining the leg lifted to a predetermined height; An ankle pump member disposed in front of the leg support on the base plate and generating a pumping action by pushing up the blood in the calf vein (vein) according to the pulse signal received from the pulse detection unit. It relates to an automatic ankle pump device based on biosignals.

In general, ankle pump exercise refers to the process of hitting the area close to the calf (hereinafter referred to as "ankle" for convenience) from the Achilles tendon while alternately lifting and dropping both legs in a lying or sitting position, thereby repeating the process of hitting the foot and It refers to an exercise that can improve the blood circulation of the body by forcibly transporting the blood that has deteriorated to the calf side toward the heart.

Figure 1a) is a photograph for explaining a conventional manual ankle pump exercise, Figure 2 is an exemplary view comparing the posture during the ankle pump exercise.

Conventionally, when performing an ankle pump exercise, a circular or semicircular ankle pump having a predetermined length and diameter is provided, and the circular or semicircular ankle pump is placed horizontally on the lower part of the ankle in a lying or sitting position. An ankle pump exercise was performed by alternately lifting and dropping the right foot and the left foot so that the right ankle and the left ankle alternately collide with the circular or semicircular ankle pump.

However, this conventional ankle pump exercise method is not helpful at all for the elderly who have difficulty lifting their legs, and the user lifts the legs using leg muscles and then drops them, resulting in a lot of fatigue. It also had problems with not being helpful or less effective for people suffering from varicose veins, where the venous valves were damaged. In addition, noise caused by hitting during exercise could cause inter-floor noise, so it was inevitable to shrink psychologically during exercise.

Figures 1b) and 1c) is the "ankle pump health device" of Korean Patent Laid-open Publication No. 10-2005-0023811 disclosed to solve this problem, and is located at a certain height through a vertical band at the rear of the base plate, and the ankle is raised.

On the other hand, a desirable ankle pump exercise posture is to pull the tip of the toe tightly when lifting the leg so that the bent veins (extruded veins) of the ankle are stretched, and when dropping the leg, release the force and drop so that the soleus muscle contracts and stretches to improve blood circulation. can lead to promotion of The reason for this is that the soleus muscle wraps around the vein as shown in FIG. 3b). When the force is released, the vein swells and opens up so that the blood rising from the foot side can come up. This is because the venous valves close and the upper valves open, returning blood to the heart.

However, the ankle pump devices disclosed in the prior art, including the ankle pump health device of FIGS. 1b) and 1c), simply provide a function of automatically lifting and dropping the user's leg, so that the bent veins of the ankle are straightened.

Hereinafter, the automatic ankle pump device according to the present invention will be described in more detail with reference to the accompanying drawings.

In the present invention, the ankle pump exercise is an exercise that can facilitate the blood circulation of the body by stimulating the lower calf just above the ankle to forcibly transfer the blood whose flow in the foot and calf side has deteriorated. It refers to movement to help flow.

3a) and 3b) show the principle of blood circulation and the structure of the lower extremities for understanding the ankle pump movement. The venous valve under the soleus muscle is closed while the vein is pressed when force is applied, and the upper valve is opened to allow blood to return to the heart. However, this help also occurs only when the soleus muscles are moved, so people in occupations where they sit still or maintain a standing posture for a long time without moving their legs do not receive help from the soleus muscles, so blood pools in their legs, and if this phenomenon is repeated, This causes the venous valves to stretch, resulting in varicose veins, which leak blood into the feet.

In addition, as shown in FIG. 2, if the foot is spread outward during the ankle pump exercise, the pump device stimulates the calf bone (fibula) side, not the vein, so it is not helpful at all, and even when the tip of the toe is lying down, the vein can be effectively stimulated. Therefore, the effect of exercise is bound to be reduced.

In the ankle pump device for the above-described ankle pump exercise, the present invention automatically gathers the feet in a state in which the leg is lifted, and then raises the toe to perform the pump exercise through an ankle pump member to be described later in a state in which the bent veins of the ankle are stretched. It is a technical feature that it is possible to provide an excellent exercise effect by making it happen.

The mounting member 220 is to insert the foot at a predetermined height from the ground so that the leg is maintained in a lifted state, and extends vertically from the bottom plate 221 on which the heel is seated and the rear edge of the bottom plate The vertical plate 222 is integrally formed, and when viewed from the side, approximately "

“It is made in the shape of a ruler.

The bottom plate 221 is coupled to the upper end of the vertical panel 202 installed upright on the base plate 100 and is disposed at a predetermined height from the ground, so that the feet are seated at a predetermined height from the ground while being seated on the upper surface support

The bottom plate 221 is preferably formed with a predetermined width so that the heel portion can be stably seated while sufficiently contacting, and preferably has a sufficient length to support both feet at a predetermined interval.

The vertical plate 222 extends vertically from one edge of the sole plate 221, so that when a user places his/her foot on the sole plate, it adheres to the sole of the foot so that the tip of the toe is naturally erected.

In the case of the pump device of FIGS. 1b) and 1c), it only provides a function of automatically lifting and dropping the leg, so it is possible to exercise with the toes lying down while the feet are spread outward according to the user's age or health condition. There may be a problem in which the effect is remarkably low, and there is an uncomfortable problem in which an effort to put the feet together and then to stand up is required to maintain a correct posture.

The holding member 220 according to the present invention is in the form of forcibly erecting the foot by a vertical plate when the user lifts the leg and puts the foot, and can prevent the tip of the toe from lying down.

Next, the alignment member 230 is a member that aligns both feet so that the feet inserted into the holding member are gathered in the center so that both feet are erected.

As shown in FIG. 7, a drive motor 231 for alignment is provided on one side of the rear surface of the vertical plate, and a transfer screw 232 for alignment connected to the drive motor for alignment and rotated by power is connected to one end of the vertical plate. It is arranged along the horizontal direction at the rear of the

The rear surface of the alignment plate 233 passes through the vertical plate and is screwed with a transfer screw for alignment at the rear of the vertical plate.

Here, threads 2321 and 2322 are formed in different directions on both sides of the transfer screw 232 for alignment based on the center, so that when the drive motor 231 for alignment is driven, the alignment plates 233 on both sides simultaneously They move inward and become closer to each other.

When the user places their feet on the bottom plate 221, they naturally spread outward. When the driving motor 231 for alignment is operated, the alignment plate 233 gradually moves from the outside to the inside along the transfer screw 232 for alignment. While moving, the foot that is widened outward can be gathered inward so that the foot can be erected.

In addition, a plurality of fixing brackets 235 and guide rails 234 are provided on the rear surface of the vertical plate 222 to prevent shaking when the alignment plate 233 moves, and the bottom plate 221 An auxiliary alignment plate 223 is provided in the center to support the inner edge of the foot while dividing the space on the bottom plate into two, so that the feet gathered in the center by the alignment plate 233 are naturally erected.

Next, the standing member 240 is a member that presses the front heel of the foot erected by the alignment member 230 to stand the toe.

Referring to FIG. 7, a driving motor 241 for standing is disposed above the driving motor for alignment on the rear surface of the vertical plate, and a power transmission shaft 242 rotates by being connected to the driving motor for standing at one end. It is disposed along the horizontal direction at the rear of the vertical plate.

In addition, a cam 243 performing an eccentric movement is fitted to the power transmission shaft 242, and a pressing hole 245 protruding forward through the vertical plate by the eccentric movement of the cam is provided in front of the cam. do.

When the power transmission shaft 242 is rotated by the driving motor 241 for standing while the sole of the user's foot is in close contact with the vertical plate 222, the pressing sphere 244 moves along the vertical plate due to the eccentric movement of the cam 243. It protrudes forward and pushes the forefoot, which causes the toe to be erected and the bent veins in the ankle to be stretched.

In addition, as the power transmission shaft 242 is continuously rotated by the standing drive motor 241 and the cam 243 falls naturally with the pressing part 244, the pressing part 244 is pressed by the sole of the foot and returns to the original position. And again, the cycle in which the cam 243 protrudes the pressing port 244 forward to push the forefoot is repeated.

On the other hand, it is preferable that a pair of the cam 243 and the pressurizing part 245 be spaced apart from each other at a predetermined distance so that the soles of both feet can be pressed, and the pressing part 235 can sufficiently contact the forefoot. It may be made in an appropriate shape, for example a cube or cuboid shape. In addition, at the rear of the vertical plate, a pair of guide brackets 244 are provided on the power transmission shaft 242 to guide the cam 243 to move smoothly without shaking when the cam 243 is moved back and forth by the power transmission shaft 242. It may be disposed on both sides of the cam 243.

In the present invention, since the pump exercise is performed by the ankle pump member in a state in which the bent veins of the ankle are stretched by standing the tip of the toe through such a standing member 240, excellent exercise effects can be expected.

Next, Figures 8 and 9 is a schematic illustration showing the ankle pump member 300 according to a preferred embodiment of the present invention.

The ankle pump member 300 is a member that is disposed in front of the leg support member 200 on the base plate and causes a pumping action by pushing up blood in the veins (veins) of the calf.
