Fixed brace of sufficient enstrophe

Technical Field

The invention relates to the technical field of neurosurgery nursing, in particular to a fixed support for pronation.

Background

Neurosurgery is mainly used for treating nervous system diseases of brain, spinal cord and the like caused by trauma, for example, the cerebral hemorrhage and bleeding amount endanger life, the brain trauma caused by car accidents, or the brain is pressed by tumors and needs to be treated by operations, and the like, the brain spirit of the patients is usually damaged, and the patients have adverse effects on the strength and coordination of other parts of the body and usually show hemiplegic conditions (one side of the limb is not controlled);

the condition of the pronation is usually accompanied by the hemiplegia patient, because the cerebral hemorrhage or the brain injury of the patient has substantial loss of the brain, the stretch reflex loses the adjustment of the advanced center, and further the muscle tension imbalance (caused by the imbalance of the muscle tension in the inner and outer limbs) is caused, and in addition, the one limb of the hemiplegia patient cannot be fully exercised, so the muscle atrophy, the muscle fascia traction and other conditions are caused, and the condition of the pronation is further aggravated;

aiming at the situation that a hemiplegic patient needs to strengthen the movement exercise of the limb at one side of the hemiplegic patient in daily nursing, such as walking by leaning on a walking stick, the limb at one side of the hemiplegic patient is dragged by the strength of the body to complete the basic walking exercise (the training of the limb at one side of the hemiplegic patient is realized, and the function of recovering the limb at one side as much as possible is facilitated), because the hemiplegic patient is accompanied with the condition of foot varus, a fixed support is usually worn on the foot at one side of the hemiplegic patient in the walking exercise process, and the phenomenon that the foot bottom is unstably contacted with the ground (when the foot is lifted to contact with the ground) due to the foot varus in the walking process is avoided;

the existing foot fixing brace is generally used for fixing the foot of a patient with a foot varus symptom relative to the fixing brace by using a bandage or other fixing measures, and the fixing brace is fixed at the position of the lower leg of the patient, so that the foot of the patient cannot generate the varus phenomenon relative to the lower leg (the phenomenon of numbness, convulsion, spasm, paralysis and the like caused by the fact that foot muscles are subjected to large compression force for a long time) is realized;

in view of the above, we provide a varus fixation brace to solve the above problems.

Disclosure of Invention

The foot varus fixing brace provided by the invention can correspondingly adjust the binding degree of the feet of a patient according to the rhythm in the walking process of the patient, slightly reduces the binding force on the feet when the feet with the foot varus symptom stand on the ground, increases the binding force on the feet when the feet with the foot varus symptom of the patient lift up, ensures that the muscles of the feet are not always in a state of being pressed by larger binding force, reduces the binding force when the feet fall to the ground, increases the binding force when the feet lift up and repeatedly and alternately performs, and can also realize the massage effect on the feet of the patient to a certain degree.

The foot varus fixing support comprises a wearing frame, wherein the wearing frame comprises a horizontal part and a vertical part which are integrally arranged, and is characterized in that a sunken cavity is arranged on the bottom wall of one transverse side of the horizontal part, a silica gel pad is arranged at the upper end of the sunken cavity, and a plurality of contact plates which are vertically slidably mounted and elastically connected with the silica gel pad are longitudinally arranged in the sunken cavity below the silica gel pad at intervals;

vertical interval is equipped with two spacing framves and spacing frame interior arcwall face with it vertical slidable mounting on the horizontal part and installs the foot gasbag body, the horizontal both sides of vertical portion are equipped with the shank gasbag body, sink the chamber through gas device respectively with the foot gasbag body, shank gasbag body coupling, gas device, the foot gasbag body, the shank gasbag body satisfies: when the foot is lifted, the gas device respectively inflates the foot airbag body and the leg airbag body, and when the foot is supported, the gas device extracts the gas in the foot airbag body and the leg airbag body.

The beneficial effects of the technical scheme are as follows:

(1) The scheme can correspondingly adjust the binding degree of the feet of the patient according to the rhythm in the walking process of the patient, slightly reduces the binding force to the feet when the feet with the foot varus symptom stand on the ground (the weight of the patient is concentrated on the feet, and the feet cannot be inverted due to the downward pressure), increases the binding force to the feet when the feet with the foot varus symptom of the patient lift up (the feet are in a suspended state so as to avoid the involuntary generation of the feet due to the unbalanced muscle tension), ensures the safety of the walking process, ensures that the muscles of the feet cannot be always pressed by larger binding force, reduces the binding force when the feet fall to the ground, increases the binding force when the feet lift up, and repeatedly and alternately performs, and also can realize the massage effect on the feet of the patient to a certain degree;

(2) In the scheme, when the foot with the foot varus is lifted, acting forces with different sizes are applied to the two sides of the lower leg of the patient (the acting force outside the lower leg is larger than the acting force inside the lower leg), so that the massage to the lower leg of the patient is realized, and the foot can be further prevented from being involuntarily inverted when lifted (the acting force outside the ankle is larger, the ankle is prevented from inclining outwards, and the trend that the foot turns over inwards is also prevented);

(3) In this scheme, through setting up silica gel pad, cavity, massage post isotructure, can realize lifting up the time-out as patient's foot, utilize the effect of negative pressure to inhale patient's sole and stack up at silica gel (further restrain the inboard upwarp of foot and ankle position extroversion), still can realize carrying out the effect of massaging to patient's sole (play and relax sole muscle, alleviate tired effect).

Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which reference is made to the accompanying drawings.

Embodiment 1, this embodiment provides a fixed brace for pronation, as shown in fig. 1, including a wearing frame (the wearing frame includes a horizontal portion 1 and a vertical portion 2 which are integrally arranged, and is made of hard and light composite plastic), so as to achieve a better limiting effect on limbs (feet and lower leg portions) on one side of a patient with hemiplegia, and avoid muscle tension imbalance caused by the hemiplegia, so that the feet of the patient turn inwards during walking exercise (as shown in fig. 10, specifically, the inner sides of the limbs on the side of the hemiplegia tilt upwards, and the ankle portion tilts outwards), a layer of flexible material (such as a sponge body and a rubber pad) can cover the contact portion between the inner sides of the horizontal portion 1 and the vertical portion 2 and the limbs of the patient, so that the patient has a certain comfort level when wearing the brace, tightening belts 30 are vertically arranged at two sides of the vertical portion 2 at intervals (the free ends of the lower leg tightening belts 30 are adhered to the side walls of the vertical portion 2 through magic tapes), and a limiting effect on the patient is achieved;

when the limb on one side of the patient with hemiplegia takes off the ground, the foot of the patient is involuntarily inverted due to unbalanced muscle tension (the inner side of the foot surface is upwarped, the ankle part is outwards inclined, as shown in the right side view of the attached drawing 10), when the foot of the patient touches the ground in the posture, the gravity center is easily unbalanced due to unstable contact of the sole part and the ground, and the condition of falling down is easily caused (the ankle part is seriously twisted, and the pain of the patient is aggravated);

the improvement of the scheme is that: as shown in figure 4, be equipped with down heavy chamber 3 and the 3 upper ends in the chamber that sink on the diapire that is in 1 horizontal one side of horizontal part and be equipped with silica gel pad 4 (silica gel pad 4 up end keeps the parallel and level with 1 diapire of horizontal part, silica gel pad 4 bonds together through high strength glue and 3 lateral walls in the chamber that sinks all around, silica gel pad 4 constitutes a sealed cavity with the chamber 3 that sinks jointly, vertical interval is equipped with a plurality of touch panel 5 and are supported and be connected with the spring between the chamber 3 that sinks (touch panel 5 is supported in the spring action its up end face and is supported in terminal surface under silica gel pad 4) down, as shown in figure 1, the interval is equipped with two spacing framves 6 with the vertical slidable mounting of 1 lateral wall of horizontal part 6 (rotate on horizontal part 1 and install lead screw 33 with spacing frame 6 screw-thread fit, through rotating the height of adjustable spacing frame 6 of lead screw 33), install gasbag body 7 on the arcwall in spacing frame 6, install shank gasbag body 8 on two inside walls of vertical part 2, be equipped with the air duct 34 and the gas device that sink the chamber 3 intercommunication that sink respectively in 1 both sides of horizontal part, gas duct and be connected with the gas device, gas device is respectively, this shank 7 when concrete messenger's time:

this wearing frame is dressed at first with patient's hemiplegia one side shank, make patient's foot pass two spacing 6 in proper order, then tighten the tight belt 30 with patient's shank and realize spacingly, control two spacing 6 height of difference in vertical (because the human foot is higher than uneven above the human foot, the performance is highly rised after the foot from the foot gradually) through rotating lead screw 33, so when adjusting two spacing 6, make 6 height that highly suitably are higher than the height of front side spacing 6 of spacing that are located the rear, the distance that two spacing 6 moved down satisfies: the lower end face of the limiting frame 6 is in contact with the upper end face of the foot part but does not generate pressure, the implementation process of the scheme is described by taking the right foot of the patient as the foot turning inwards, so that when the sinking cavity 3 is arranged, the position of the sinking cavity is arranged at the position of the horizontal part 1 close to the inner side (as shown in the attached drawing 1, the inner side and the outer side in the scheme are described based on the position of the human body when the human body stands, one side close to the center of the human body is called as the inner side, and the side far away from the center of the human body is called as the outer side);

after the patient wears the fixed brace, the patient can walk and exercise, because one side of the limb is not controlled (or the ability of the brain to control the side of the limb is greatly reduced), in the walking process, the patient can drag the leg on the hemiplegic side to move forwards under the action of the trunk of the patient, the walking exercise is completed by matching the left side limb, when the right foot of the patient does not fall on the ground (in a suspended state), the silica gel pad 4 is not stressed, the upper end surface of the silica gel pad is kept level with the bottom wall of the horizontal part 1 (at the moment, a certain amount of air is filled into the foot air bag body 7 and the leg air bag body 8 under the action of the air device and expands), and through the matching of the limiting frame 6 and the foot air bag body 7, the restraint force applied to the dorsum of the foot of the patient is further increased (so as to prevent the foot of the patient from involuntary varus due to unbalanced muscle tension when the side limb is in a suspended state), and the position of the lower leg of the patient is further limited by the cooperation of the leg air bag body 8 and the tightening belt 30, so that the foot of the patient with the lateral hemiplegic limb is always in a correct position and posture before falling to the ground (so as to prevent the side limb from involuntary varus due to unbalanced muscle tension when the side limb is suspended, so that the side limb is unstable in contact with the ground when falling to the ground, and the center of gravity is unbalanced to cause the patient to fall down and further damage the patient);

when the patient falls to the ground, the right foot of the patient presses the silica gel pad 4 downwards (the touch plate 5 is forced to compress the spring connected with the touch plate and move downwards, so that the silica gel pad 4 generates a depression), so that the gas originally positioned in the sunken cavity 3 is squeezed into the gas device through the gas guide pipe 34 and drives the gas device to act, the air originally positioned in the foot airbag body 7 and the leg airbag body 8 is exhausted outwards under the action of the gas device, and the foot with the foot inward turning symptom of the patient is pressed on the ground (the foot is tightly pressed on the ground under the action of the self gravity), so that the inner side of the foot of the patient cannot be upwarped and the outer part of the ankle cannot be outwards inclined (when the gravity is applied to the limb from top to bottom, the foot cannot be easily turned inwards), and therefore, the situation that the patient cannot appear as shown in the right side view in the attached drawing 10 when the foot with the foot inward turning is lifted to fall to the ground (the patient is prevented from contacting the right side view in the drawing 10 and the ground is uniformly fallen to the patient;

the process is a complete walking process, the walking exercise can be carried out under the condition of taking certain safety protection measures for the patient by repeating the process, in the walking process, the foot of the patient is restrained to a greater degree only when the limb on the hemiplegia side of the patient is lifted (so as to prevent the phenomenon of involuntary inversion caused by unbalanced muscle tension when the limb on the hemiplegia side is suspended and is not influenced by external force), the state is continuously kept until the foot with the foot inversion touches the ground and stops, when the limb on the hemiplegia side of the patient touches the ground, the restraining force on the foot of the patient is reduced (so that the foot on the hemiplegia side of the patient cannot be always in the action of larger restraining force), and the phenomena of numbness or twitching, spasm and the like of the foot muscle with the symptom of the foot inversion caused by the larger restraining force (the damage degree of the limb on the hemiplegia side of the patient is increased, and the recovery of the foot muscle is not facilitated) are reduced as much as possible;

meanwhile, along with the walking process, the foot air bag body 7 and the leg air bag body 8 adjust acting forces applied to the feet (the instep and the two sides of the lower leg part) of the patient at regular intervals under the action of the air device (the adjusting time depends on the walking speed of the patient), the acting force applied when the limb on one side of the hemiplegia is lifted is larger, the acting force applied after the limb on one side of the hemiplegia is contacted with the ground is smaller, and the mode is circularly and repeatedly performed, so that the effect of massaging the instep and the two sides of the lower leg part of the patient is realized indirectly (the massage is beneficial to relaxing the muscles of the foot and the lower leg part of the limb on one side of the hemiplegia to a certain degree in the walking exercise process).

Embodiment 2, on the basis of embodiment 1, as shown in fig. 1, the gas device includes primary box bodies 9 installed on both lateral sides of the vertical portion 2 and both communicated with the sink cavity 3 (the bottom of the primary box body 9 is communicated with the sink cavity 3 through a gas conduit 34, each primary box body 9 corresponds to one foot airbag body 7), the upper ends of the foot box bodies 12 are respectively communicated with the corresponding foot airbag bodies 7 through conduits, and one ends of the conduits, which are close to the corresponding foot airbag bodies 7, are communicated with the foot airbag bodies 7 through pressure-resistant hoses (to match the position movement of the limiting frame 6);

(1) As shown in fig. 5, when a foot on the side with the foot varus touches the ground (at this time, a certain amount of air is filled in the foot airbag 7 and the leg airbag 8), the silicone cushion 4 is pressed and transmitted to the touch plate 5 (as shown in fig. 6, a plurality of touch plates 5 are arranged at intervals in the sunken cavity 3), and then the touch plate 5 is forced to move downwards and press the spring connected with the touch plate 5, and finally the silicone cushion 4 is sunken (the volume of the sunken cavity 3 is reduced), a part of air originally in the sunken cavity 3 is squeezed into the primary box 9 arranged on two sides of the vertical part 2 through the air duct 34, and the primary plate 10 vertically and slidably arranged in the primary box 9 is forced to move upwards (the spring is connected between the primary plate 10 and the primary box 9), the foot plate 11 is driven to move downwards through the first reversing mechanism along with the upward movement of the primary plate 10, as shown in fig. 1, the bottom of the foot box 12 is communicated with the outside, and the air originally in the foot airbag 7 in the box 12 along with the downward movement of the foot plate 11 is pumped into the box 12 (when most of the air in the foot airbag 11, and the air bag 12 is exhausted out of the foot box 7 (the foot box 12), and the foot restraint plate 12, and the air bag 12 is obviously discharged out of the foot restraint of the patient;

simultaneously with the above process: the upper end of the primary box body 9 is communicated with a leg pneumatic mechanism, and along with the primary plate 10 moving upwards in the primary box body 9, the gas originally in the space above the primary plate 10 is squeezed into the leg pneumatic mechanism and the gas originally in the leg air bag body 8 is pumped outwards through the leg pneumatic mechanism (so that the leg air bag body 8 becomes relatively dry and shriveled, and the binding force of the leg air bag body 8 on the lower leg of the patient is obviously reduced);

(2) When the foot on the hemiplegic side of the patient is lifted, the pressure of the foot on the silica gel pad 4 is gradually reduced until the silica gel pad 4 is completely separated from the ground, the pressure on the silica gel pad 4 is minimum at the moment, then the plurality of touch plates 5 move upwards under the action of the springs connected with the touch plates and synchronously drive the concave silica gel pad 4 to be upwards supported, negative pressure of a certain degree is generated in the sinking cavity 3 at the moment, so that air originally squeezed into the primary box 9 flows back into the sinking cavity 3 (the primary plate 10 synchronously moves downwards under the action of the springs connected with the primary plate), the foot plate 11 is driven to move upwards through the first reversing mechanism, the air in the space above the foot plate 11 is squeezed into the foot air bag corresponding to the foot plate again (the foot air bag expands again at the moment), and the constraint force exerted on the instep of the patient is obviously increased;

in synchronization with the above process: along with the downward movement of the primary plate 10, the gas originally squeezed into the leg pneumatic mechanism is returned to the primary box body 9, and the gas is filled into the leg air bag body 8 of the box again under the action of the leg pneumatic mechanism, so that the leg air bag is expanded, and when the silica gel pad 4 is restored to the initial position, the leg air bag body 8 and the foot air bag body 7 are synchronously expanded to the maximum degree (at the moment, the constraint force applied to the foot and the two sides of the lower leg of the patient is obviously increased), so that when the limb on one side of the hemiplegia of the patient is lifted, a good limiting and fixing effect is realized (under the condition that the limb is lifted and is not constrained by external force, an insufficient inward turning phenomenon is generated due to muscle tension unbalance).

Embodiment 3, on the basis of embodiment 2, as shown in fig. 2, the leg pneumatic mechanism includes a secondary box 13 communicated with both the primary boxes 9, a secondary plate 14 is slidably mounted in the secondary box 13 (a spring is connected between the secondary plate 14 and the secondary box 13), the upper end of the secondary box 13 is communicated with the outside, the secondary plate 14 is driven by a second reversing mechanism to have two leg plates 15, and leg boxes 16 matched with the leg plates 15 are respectively arranged on the side walls of the vertical portion 2 (the leg plates 15 are vertically slidably mounted in the leg boxes 16, the bottom walls of the leg boxes 16 are communicated with the outside, and the upper ends of the leg boxes 16 are respectively communicated with the corresponding leg airbag 8);

when the foot of the limb on one side of the hemiplegia of the patient touches the ground, the gas originally in the space above the primary plate 10 is squeezed into the secondary box body 13 from the primary box body 9 (the air above the primary plate 10 in the two primary box bodies 9 is squeezed into the secondary box body 13), the secondary plate 14 is forced to move upwards in the secondary box body 13 (a spring connected with the secondary plate 14 is compressed), the leg plate 15 is synchronously driven to move downwards in the leg box body 16 by the synchronous second reversing mechanism along with the upward movement of the secondary plate 14, the gas in the leg airbag 8 is extracted outwards and is pumped into the leg box body 16 (the space above the leg plate 15), and the constraint force of the two leg airbag 8 on the lower leg of the patient is obviously reduced;

when the limb on one side of the hemiplegia of the patient is lifted, negative pressure is generated to a certain degree in the sunken cavity 3, so that the gas originally extruded into the secondary box body 13 flows back into the two primary box bodies 9 respectively (the gas in the space above the primary plate 10 flows back into the sunken cavity 3), the leg plate 15 is synchronously driven to move up in the leg box body 16 through the second reversing mechanism along with the downward movement of the secondary plate 14, then the gas is inflated into the leg airbag 8, so that the foot is completely separated from the ground, and the leg airbag 8 and the foot airbag 7 are both inflated to the maximum degree (at the moment, the restraint force of the leg airbag 8 and the foot airbag 7 on the patient is obviously increased).

Embodiment 4, on the basis of embodiment 3, one of the leg plates 15 is made larger in size (larger in cross-sectional area) than the other leg plate 15 during installation, and because the right limb is illustrated as a hemiplegic example in the present embodiment, the leg plate 15 corresponding to the outer leg airbag 8 is made larger in size (the other leg plate 15 corresponds to the inner leg airbag 8) during installation, and the leg box 16 corresponding to the outer leg airbag 8 is also made larger, in this embodiment, the two leg airbags 8 are located at lower positions so as to correspond to the limb of the lower leg of the patient near the foot;

when the foot of the patient with the foot varus symptom is lifted from the ground, the primary box body 9, the secondary box body 13 and the second reversing mechanism are matched to synchronously drive the two leg plates 15 to move upwards in the corresponding leg box bodies 16, and because the leg box bodies 16 corresponding to the leg air bags 8 on the outer sides have larger sizes, when the two leg plates 15 move upwards for the same distance, the air squeezed into the leg air bags 8 on the outer sides can be redundant of the air in the leg air bags 8 on the inner sides, so that the expansion degree of the leg air bags 8 on the outer sides is larger than that of the leg air bags 8 on the inner sides, as shown in the attached figure 10, because the leg air bags 8 on the outer sides expand to a larger degree than that of the leg air bags 8 on the inner sides (the ankle position of the foot of the patient is subjected to the restraining force applied from the leg air bags 8 on the outer sides is larger than that applied by the leg air bags 8 on the inner sides), the ankle position of the foot of the patient can be well inhibited from self-inclining outwards due to muscle tension when the foot of the patient is lifted, so that the limb on the side of the patient can always keep the limb in a correct suspended state, and finally train the limb in a correct walking posture (the correct walking process is finished);

in this scheme, between primary plate 10, elementary box 9, between foot board 11, the foot box 12, between secondary plate 14, the magnetic pole box, all be equipped with rubber seal between shank board 15, the shank box 16 in order to ensure the gas tightness, provide a first reversing mechanism, second reversing mechanism's embodiment in this implementation: as shown in fig. 1, the first reversing mechanism includes racks (a gear rotatably mounted on the vertical portion 2 is engaged between two racks) respectively disposed outside the primary box 9 and the foot box 12 and connected to the primary board 10 and the foot board 11, as shown in fig. 2, the second reversing mechanism includes racks disposed outside the secondary box 13 and connected to the secondary board 14, two leg boards 15 are commonly connected to a U-shaped rod (two cantilevers of the U-shaped rod are slidably mounted to bottom walls of the two leg boxes 16, respectively), one cantilever of the U-shaped rod is disposed at one end outside the leg box 16 and is provided with a plurality of tooth systems, a gear rotatably mounted on the vertical portion 2 is engaged between the plurality of tooth systems and the racks, the first and second reversing mechanisms have the same working principle, and achieve a reversing effect through gear and rack transmission (of course, the reversing mechanism in the scheme is not limited to the above structure, as long as the same effect can be achieved).

Embodiment 5, on the basis of embodiment 1, as shown in fig. 4, a plurality of cavities 17 are uniformly distributed on the upper end surface of the silicone pad 4 located right above the touch panel 5, a hole 18 penetrating through the silicone pad 4 is arranged at the center of the cavity 17, as shown in fig. 5, a one-way pipe 19 (composed of an L-shaped pipe and a one-way valve arranged on the L-shaped pipe) communicated with the hole 18 is installed on the touch panel 5, a plurality of one-way pipes 19 located on the same touch panel 5 are commonly communicated with an exhaust pipe 20 arranged in the sunken cavity 3 (the plurality of one-way pipes 19 are communicated with the exhaust pipe 20 corresponding thereto through a pressure-resistant hose), and the exhaust pipe 20 is communicated with an exhaust hole 32 (the exhaust hole 32 is communicated with the outside) arranged in the horizontal portion 1, when the foot of the patient touches the ground, the pressure applied on the silicone pad 4 is gradually increased, so that the foot completely stands on the ground (at this time, the pressure applied to the foot of the silicone pad 4 is the largest);

as shown in the upper view of fig. 7, which is a schematic structural diagram of the cavity 17 when the patient's foot is lifted (at this time, the patient's foot hardly generates pressure or has little pressure on the silicone pad 4), at this time, the cavity 17 is filled with air, when the patient's foot touches the ground, the silicone pad 4 is continuously compressed (the silicone has good tension, flexibility and compressibility) under the action of its own gravity, so as to be changed into the state shown in the lower view of fig. 7, at this time, the patient's sole position tightly abuts against the upper end face of the silicone pad 4 (the cavity 17 and the patient's sole face cooperate to form a relatively sealed space), the volume of the cavities 17 is reduced due to the shrinkage deformation generated by the extrusion of the silicone pad 4, and in the process that the silicone pad 4 is extruded from the upper view to the lower view of fig. 7, the volume of the cavity 17 is continuously reduced, so that the air originally in the cavity 17 is discharged into the one-way tube 19 communicated therewith through the duct 18 and finally collected into the exhaust duct 20 and discharged outward through the exhaust hole 32 (as shown in fig. 5);

when the limb on the side of the patient is lifted, namely when the foot is gradually separated from the ground, the acting force applied by the foot to the silica gel pad 4 is synchronously reduced, the silica gel pad 4 is gradually restored to deform, the volume of the plurality of cavities 17 is gradually increased, and because part of air originally located in the cavities 17 is exhausted outwards through the pore passage 18, the one-way pipe 19, the exhaust pipe 20 and the exhaust hole 32, a relative negative pressure environment (external air cannot enter the cavities 17 through the exhaust hole 32, the exhaust pipe 20 and the one-way pipe 19) is generated in the cavities 17, and the foot of the patient is tightly pressed on the silica gel pad 4 under the action of the external atmospheric pressure (the fixing effect on the foot of the patient is realized when the foot of the patient is separated from the ground), and the silica gel pad acts together with the foot airbag body 7 and the leg airbag body 8, so that the better fixing effect is realized when the foot of the patient is separated from the ground;

as shown in fig. 6, in this embodiment, the contact portions of the touch panel 5 and the silicone pad 4 are bonded together by high-strength glue, when the foot of the patient is detached from the ground, the touch panels 5 move up synchronously to move up to the initial position, and cannot move up continuously (the two side walls of the lower sinking cavity 3 are respectively provided with a slideway which is vertically and slidably mounted with the two ends of the touch panel 5, and are not numbered in the figure, so that when the foot is completely detached from the ground, the touch panel 5 moves up to the top position of the slideway under the action of a connecting spring, and at this time, the corresponding positions of the bottom of the foot of the patient and the cavity 17 are tightly pressed on the silicone pad 4 under the action of negative pressure, and at this time, the bonding portion of the silicone pad 4 and the touch panel 5 cannot move up continuously, so that the effect of limiting the foot of the patient (making the foot tightly bonded on the silicone pad 4 so as to avoid the inner side foot upwarp phenomenon shown in fig. 10 when the foot is detached from the ground) is achieved;

as shown in fig. 6, the concave cavities 17 are not formed in the area of the silicone pad 4 close to the inner side, because the inner side of the sole surface of the human body is spaced from the ground at a certain distance when the human body walks, that is, when the patient wears the device to walk, the inner side of the sole surface is not pressed on the silicone pad (and further no additional concave cavity is needed), and certainly, when the sole surface of the patient is pressed on the silicone pad, the concave cavities 17 formed on the silicone pad 4 are not all pressed (part of the concave cavities are in contact with the sole surface of the patient and can form a relatively sealed space, so that the preset effect in the scheme can be achieved);

note: when this fixed brace of dress was taken exercise to the patient in this scheme, the foot of its hemiplegia one side should be in naked state (need not to wear socks) for when its foot pressed on silica gel pad 4, can fully contact between silica gel pad and the patient plantar surface (can closely laminate the contact between terminal surface and the plantar surface on the silica gel pad) and constitute a space sealed relatively with cavity 17.

Example 6, on the basis of example 1, as shown in fig. 4, the bottom wall of the horizontal portion 1 is configured to be a slope 21 when being configured, and since this solution is described by taking the side of the patient with no hemiplegic limb on the right side as an example, the slope 21 is configured to be higher on the outer side and lower on the inner side, as shown in the right side view of fig. 10, when the foot of the patient presses on the upper end surface of the horizontal plate, the foot of the patient tends to incline to the inner side, thereby balancing the stress on the sole of the patient (to achieve the effect of suppressing the upwarp of the inner side of the foot surface and the outward tilt of the ankle portion);

as shown in fig. 4, when the foot massage device is installed, the upper opening of the sinking chamber 3 is also set to be the inclined plane 21 and the slope of the bottom wall of the horizontal part 1 is kept consistent, when the foot of the patient is pressed on the silica gel pad 4 near the inner side area, the silica gel pad 4 is made to be concave, so that the slope of the inclined plane 21 in the area range of the silica gel pad 4 is increased, the slope of the inclined plane 21 pressed by the foot of the patient near the outer side is smaller than the slope of the inclined plane 21 pressed by the foot of the patient near the inner side, and the inward upwarp of the foot surface and the outward tilt of the ankle part are further inhibited.

Embodiment 7, on the basis of embodiment 5, as shown in fig. 9, the duct 18 and the one-way pipe 19 are communicated with each other through a transition pipe 22 (the transition pipe 22 is a hard pipe), a massage column 23 is vertically slidably installed coaxially with the center in the transition pipe 22 (a spring is connected between the massage column 23 and the transition pipe 22, a bearing rod is radially arranged in the transition pipe 22, so that the massage column 23 is slidably installed on the bearing rod, the length of the bearing rod is the same as the inner diameter of the transition pipe 22, the width of the bearing rod is far smaller than the inner diameter of the transition pipe 22, and the bearing rod is not numbered in the drawing), one end of the spring is connected to the bearing rod, the other end of the spring is fixed to the massage column 23, one side of the transition pipe 22 is communicated with an air pressure pipe 24 (the air pressure pipe 24 is communicated with the exhaust pipe 20 through a pressure-resistant hose, and is a standard atmospheric pressure relative to a space on one side of the air pressure plate 25 away from the massage column 23), an air pressure plate 25 is slidably installed in the air pressure pipe 24 (a sealing rubber ring is arranged between the air pressure plate 25 and the air pressure pipe 24 to ensure airtightness), a connecting rod 26 is arranged between the lower end of the air pressure plate 25 and the massage column 23 (two ends of the connecting rod 26 are respectively connected with the connecting rod 26, and the inner diameter of the air pressure pipe 24 is far smaller than the transition pipe 22;

when the patient's foot is pressed on the silica gel pad 4, the top end of the massage column 23 is not contacted with the bottom surface of the patient's foot or the acting force between the top end of the massage column 23 and the top end of the pore canal 18 is small (the limiting block 29 corresponding to the air pressure plate 25 is arranged in the air pressure tube 24, the air pressure plate 25 is abutted on the limiting block 29 in the natural state), when the acting force exerted on the silica gel pad 4 by the patient's foot is gradually increased, part of the air in the cavity 17 is discharged outwards through the pore canal 18, the transition tube 22 and the one-way tube 19 (because the air pressure plate 25 is acted by the limiting block 29, when the patient's limb is separated from the ground, a certain degree of negative pressure environment is generated in the cavity 17, at the moment, the air pressure difference generated inside and outside the air pressure plate 25 forces the air pressure plate 25 to move towards the direction close to the massage column 23 (the spring connected to the massage column 23 is squeezed), the connection rod 26 synchronously drives the massage column 23 to move upwards and enables the top end face to be abutted against the bottom surface of the patient's foot (the degree of negative pressure in the cavity 17, the cavity 23 is larger, the massage column 23 is larger, the bottom surface of the patient's foot, as shown in the attached drawing, thus the patient's foot pad 4 can be partially covered on the patient's foot, and the patient's bottom surface, thereby the patient's foot can be covered under the patient's foot's bottom surface;

when the patient's limb begins to touch the ground, the pressure applied to the silicone pad 4 is gradually increased, the air pressure environment in the cavity 17 is gradually increased, in the process, the air pressure environment in the cavity 17 and the transition tube 22 is obviously increased, the air pressure difference between the two sides of the air pressure plate 25 is obviously reduced, the massage column 23 synchronously moves downwards under the action of the spring connected with the massage column (at the moment, the sole surface is also pressed on the upper end of the massage column 23 and the massage column 23 is forced to move downwards) so as to move to the initial position (at the moment, the massage column 23 is not in contact with the sole surface of the patient), and the process is a complete massage cycle.

Embodiment 8, on the basis of embodiment 7, as shown in fig. 9, in order to make the massage effect better, a magnet 27 is provided on the inner wall of the transition pipe 22 corresponding to the air pressure plate 25, and an iron piece 28 is provided on the side of the air pressure plate 25 facing the magnet 27;

initially, the air pressure plate 25 is far from the magnet 27, and the magnetic force between the air pressure plate 25 and the magnet 27 is weak (neglected), when the air pressure plate 25 moves towards the direction close to the massage column 23 under the action of air pressure difference, the distance between the iron sheet 28 and the magnet 27 is made smaller and smaller, so that when the air pressure plate approaches to a certain degree, the air pressure plate 25 is driven to move rapidly under the action of the magnetic force, the massage column 23 is synchronously driven to move rapidly upwards, and further under the action of magnetic force, the conflict force between the massage column 23 and the plantar surface is obviously increased, and the massage and stimulation effects on the plantar surface of the foot of a patient are better;

when the patient's limb begins to touch the ground, the foot bottom of the patient presses the massage column 23 to move downwards (the air pressure plate 25 is synchronously forced to move towards the direction away from the magnet 27), along with the process, the magnetic force between the air pressure plate 25 and the magnet 27 is gradually weakened, so that when the air pressure plate 25 and the magnet 27 are far away to a certain degree, the magnetic force between the air pressure plate 25 and the magnet 27 is greatly reduced (negligible) so as to complete the reset, when the foot of the patient touches the ground, the massage column 23 is not contacted with the foot bottom, and when the foot of the patient lifts, the upper end of the massage column 23 is abutted against the foot bottom (the above process is repeatedly and alternately performed to massage the foot bottom of the patient).

Note: the pressure hoses in the solution are not shown in the figures.

The above is only for illustrating the invention, it should be understood that the invention is not limited to the above embodiments, and various modifications in accordance with the spirit of the invention are within the scope of the invention.
