DETAILED DESCRIPTION
[0024] The embodiments of the present invention are described in detail below. Figures 1 to 4 , an embodiment of the present invention provides a physical therapy device for preventing foot drop and deep vein thrombosis, including a support pad 100, a connecting sleeve 200 and a driving member 300; the support pad 100 is used to support the patient's foot, and the front upper part of the support pad 100 is provided with a first deformable cavity 110; the connecting sleeve 200 is used to be sleeved on the outside of the patient's calf and / or thigh, and a second deformable cavity 210 is provided in the connecting sleeve 200; the driving member 300 is used to drive the first deformable cavity 110 and the second deformable cavity 210 to deform. When the first deformable cavity 110 is deformed, it can prompt the patient to perform passive foot dorsiflexion and passive intermittent ankle pump exercises to prevent foot drop. When the second deformable cavity 210 is deformed, it can massage and stimulate the patient's calf and / or thigh to prevent deep vein thrombosis. The "connecting sleeve 200 is used to be connected to the outside of the patient's calf and / or thigh" mentioned here means that the connecting sleeve 200 can be connected only to the outside of the calf or thigh, or the connecting sleeve 200 can be lengthened to be able to be connected to the outside of the calf and thigh at the same time, or two connecting sleeves 200 can be set, one connected to the outside of the calf and the other connected to the outside of the thigh. Specifically, it can be adjusted and used according to actual needs.
[0025] When the first deformable cavity 110 of the present physiotherapy device is deformed and expanded, it can push the sole and toes of the foot toward the head, achieving a passive foot dorsiflexion effect. When the first deformable cavity 110 is deformed and contracted, the toes fall back and reset, achieving a natural relaxation effect. Therefore, the driving member 300 drives the first deformable cavity 110 to continuously and intermittently expand and contract, which can achieve passive foot dorsiflexion and passive intermittent ankle pump movement, thereby preventing foot drop. When the second deformable cavity 210 is expanded, it can massage and stimulate the patient's calf and / or thigh to promote blood circulation. When the second deformable cavity 210 is contracted, it can release the pressure on the calf and / or thigh to avoid long-term compression of the calf and thigh. Therefore, the driving member 300 drives the second deformable cavity 210 to continuously and intermittently expand and contract, which can achieve continuous massage and stimulation of the patient's calf and / or thigh, thereby preventing deep vein thrombosis of the lower limbs. Therefore, the present physiotherapy device, by providing a first deformable cavity 110 and a second deformable cavity 210, and adopting a driving member 300 to drive the first deformable cavity 110 and the second deformable cavity 210 to continuously and intermittently expand and contract, can achieve passive foot dorsiflexion and passive intermittent ankle pump movement, and can massage and stimulate local muscles of the legs and thighs, promote blood circulation, and have the effect of preventing foot drop and deep vein thrombosis for patients who are comatose, paralyzed, or bedridden for a long time. It can reduce the occurrence of disuse syndrome in patients, promote patient recovery, and also reduce the time and physical effort spent by caregivers or family members.
[0026] Furthermore, in some embodiments, the connecting sleeve 200 can be enclosed by a cushion with a second deformable cavity 210, and a structure such as a buckle or Velcro can be set on the cushion. After the cushion is enclosed into the connecting sleeve 200 according to the size of the patient's legs, it can be fixed with a buckle or Velcro. The connecting sleeve 200 with this structure can be easily attached and detached, and can also be easily adjusted according to the leg size of different patients. In addition, the shape, structural form and number of the second deformable cavity 210 are not limited. For example, it can be integrally formed on the cushion, and the entire cushion serves as an inflatable cavity, and the second deformable cavity 210 protrudes from the surface of the cushion. When the cushion is inflated and expanded, the second deformable cavity 210 also expands and can protrude from the surface of the cushion, thereby achieving massage stimulation on the patient's calves and thighs. For another example, the second deformable cavity 210 can be a plurality of interconnected airbag structures, wherein the plurality of airbags are circumferentially distributed and connected to the connecting sleeve 200. When the connecting sleeve 200 is worn, the plurality of airbags are circumferentially distributed along the calves and thighs. When the airbags expand, massage stimulation can be achieved on the patient's calves and thighs. In this embodiment, Figure 1 As shown, the second deformable cavity 210 and the connecting sleeve 200 are of split design. The second deformable cavity 210 is a plurality of air bags that are interconnected and fixed on the inner side of the connecting sleeve 200. This structure can facilitate the fixation of the second deformable cavity 210 without affecting the structure of the connecting sleeve 200 itself. At this time, ventilation holes can be opened on the connecting sleeve 200 and structures such as Velcro can be set.
[0027] Furthermore, in some embodiments, the driving member 300 is an air pump, the output end of which is connected to a first air tube 310. The first air tube 310 is connected to the first deformable cavity 110 via a second air tube 320, and the first air tube 310 is connected to the second deformable cavity 210 via a third air tube 330. The first deformable cavity 110 and the second deformable cavity 210 are both airbags, and the first air tube 310, the second air tube 320, and the third air tube 330 are connected by a three-way joint. When the driving member 300 is activated, it can simultaneously drive the first deformable cavity 110 and the second deformable cavity 210 to inflate and deflate. Passive foot dorsiflexion and passive intermittent ankle pump exercises can be achieved by intermittently inflating and deflation of the airbags, as well as massage and stimulation of local muscles in the calves and thighs.
[0028] Furthermore, the support pad 100 includes a bottom pad 120 and a rear pad 130. The bottom pad 120 and the rear pad 130 are distributed in an "L" shape. The bottom pad 120 can be used to support the patient's foot, and the rear pad 130 can be used to fit the patient's heel to ankle. The support pad 100 with this structure is more ergonomic and can provide the patient with a more comfortable wearing effect. Specifically, the rear pad 130 has a fitting arc surface. The setting of the fitting arc surface can make the rear pad 130 better fit the patient's heel to ankle, further improving the patient's wearing comfort. Furthermore, the longitudinal section of the bottom pad 120 along its length direction is wavy, which is more ergonomic, so that the bottom pad 120 can better fit the patient's sole for support. In addition, the rear pad 130 with a fitting arc surface can also assist the support pad 100 in limiting the patient's foot, so that when the first deformable cavity 110 expands, it can push the sole of the foot to the toes toward the patient's head without pushing the support pad 100 away from the patient's head.
[0029] Furthermore, the top of the support pad 100 is provided with a plurality of first protrusions 150, and the top of the first deformable cavity 110 is provided with a plurality of second protrusions 160. While achieving passive foot dorsiflexion and passive intermittent ankle pump exercises, the patient's foot acupuncture points can also be massaged to promote blood circulation and facilitate patient recovery. Furthermore, a third protrusion can be provided on the inner side of the connecting sleeve 200. When the second deformable cavity 210 expands and presses the patient's calves and thighs, the third protrusion can also enhance the massage effect and further promote blood circulation. Furthermore, a plurality of ventilation holes 220 can be provided on the connecting sleeve 200 to facilitate skin ventilation.
[0030] Further, refer to Figure 1 and Figure 2 In some embodiments, the first deformable cavity 110 can be set longer. When the physical therapy device is worn on the patient's legs and feet, the first deformable cavity 110 can support the patient's soles to toes. The first deformable cavity 110 is longer than the patient's toes. When the air pressure pump is inflated and deflated, passive foot dorsiflexion and passive intermittent ankle pump movements can be achieved. Figure 3 and Figure 4In some other embodiments, the first deformable cavity 110 can also be set to be slightly shorter, for example, equivalent to the length of the patient's toes, as long as passive foot dorsiflexion and passive intermittent ankle pump movements can be achieved. In addition, the first deformable cavity 110 can also be set to be slightly longer and arranged in a stepped shape, with the part located at the bottom of the toes and the part located at the bottom of the sole of the foot at different heights. Therefore, during the intermittent inflation and deflation of the first deformable cavity 110, not only can passive foot dorsiflexion and passive intermittent ankle pump movements be achieved, but also toe joint movements can be promoted, further improving the rehabilitation effect. Further, referring to Figure 7 The stepped shape can be improved into a structure with a smooth transition connection. The thickness of the first deformable cavity 110 gradually decreases from front to back and is smoothly connected to the support pad 100. This structure can not only improve the wearing comfort of the patient, but also when the first deformable cavity 110 is inflated, the first deformable cavity 110 gradually expands from back to front, thereby gradually pushing the sole to toes toward the head, realizing slow dorsiflexion of the foot and promoting toe joint movement.
[0031] Further, refer to Figure 5 In some other embodiments, the support cushion 100 further includes an air cushion 140 connected to the top of the bottom pad 120, and the first deformable cavity 110 is provided at the front of the air cushion 140. When the first deformable cavity 110 is inflated and expanded, it protrudes from the top surface of the air cushion 140. The provision of the air cushion 140 can improve the support comfort of the support cushion 100 and the sole of the patient's foot, and at the same time, it can also facilitate the molding of the first deformable cavity 110. In addition, when a protrusion is provided on the air cushion 140, the air cushion 140 can also expand to a certain extent when inflated, so that the protrusion on the air cushion 140 can massage the sole of the patient's foot to promote blood circulation. Figure 7 As shown, when the first deformable cavity 110 is integrally formed at the front end of the air cushion 140, it is easier to set the first deformable cavity 110 to a shape with a high front and a low back and smoothly transition to connect with the air cushion 140. With this structure of the support cushion 100, the bottom pad 120 can be made of a hard material to improve the overall strength of the support cushion 100. By limiting the bottom pad 120 and the rear pad 130, it can be ensured that when the first deformable cavity 110 expands, the first deformable cavity 110 can push the sole of the foot to the toes toward the head. The part that fits the sole of the patient's foot uses the structure of the air cushion 140, which can also improve wearing comfort. The air cushion 140 can be bonded to the bottom pad 120, or a groove can be opened on the bottom pad 120 and the air cushion 140 can be embedded in the groove. This can not only achieve the positioning of the air cushion 140, but also facilitate the removal of the air cushion 140. Furthermore, the thickness of the bottom pad 120 can be set to about 3.5 cm, and the thickness of the air cushion 140 can be set to 2 to 4 cm.
