Further, the first three-way valve 2, the second three-way valve 3, the third three-way valve 4, the fourth three-way valve 5, the fifth three-way valve 6, the sixth three-way valve 7 and the seventh three-way valve 8 are two-position three-way electromagnetic valves, each electromagnetic valve has the characteristic of independently controlling the on-off of an air passage, each electromagnetic valve comprises 3 ports, wherein the third ports of the third three-way valve 4 to the seventh three-way valve 8 are respectively connected to the thumb air pipe 11, the index finger air pipe 12, the middle finger air pipe 13, the ring finger air pipe 14 and the small finger air pipe 15 in sequence, so that the independent control of the extending and flexing movement of the independent fingers can be realized through the third three-way valve 4 to the seventh three-way valve 8. In this embodiment, the finger control air pipes 11-15 are all installed on the back of the hand of the rehabilitation glove, when the air is pumped down to negative pressure, the finger control air pipes 11-15 are shortened, the finger is stretched, when the air is inflated to positive pressure, the finger control air pipes 11-15 are long, and the finger is buckled.

Further, as shown in fig. 1, the solid arrows in fig. 1 indicate that the air path is fixed, and the open arrows indicate that the air path is optional. When the first three-way valve 2 and the second three-way valve 3 are not electrified by default, the air path selects to pass through the second port 202 of the first three-way valve 2, the first port 201 of the first three-way valve 2, the air pump 1, the first port 301 of the second three-way valve 3 and the third port 303 of the second three-way valve 3, when the third three-way valve 4 to the seventh three-way valve 8 are not electrified, the air path selects to enable the first port of the third three-way valve 4 to the seventh three-way valve 8 to flow with the second port 202 of the first three-way valve 2, namely the air pump 1 starts to exhaust, the glove is in an extending state, the corresponding finger starts to extend, when the third three-way valve 4 to the seventh three-way valve 8 are electrified, the corresponding finger stops extending, because the second port of the third three-way valve 4 to the seventh three-way valve 8 is in communication with the second port 302 of the second three-way valve 3 at this moment, the third port 3 is selected to enable the third port 301 to flow with the third port 303, and the third three-way valve 3 is not in a sealing state, and the air pressure is not kept to extend.

Further, when the first three-way valve 2 and the second three-way valve 3 are powered on simultaneously, the air path is selected to pass through the third port 203 of the first three-way valve 2, the first port 20 of the first three-way valve 2, the air pump 1, the first port 301 of the second three-way valve 3 and the second port 302 of the second three-way valve 3, the third port 203 of the first three-way valve 2 is communicated with the outside atmosphere, at this time, if the third three-way valve 4 to the seventh three-way valve 8 are powered on, the air path is selected to enable the second port of the third three-way valve 4 to the seventh three-way valve 8 to be communicated with the first port 302 of the second three-way valve 3, the air pump 1 starts to inflate, the glove is in a buckling state, and if the third three-way valve 4 to the seventh three-way valve 8 are powered off, the corresponding fingers can stop buckling. Since the second port of the third through seventh three-way valves 4 through 8 is in communication with the second port 302 of the second three-way valve 3 at this time, the second port 302 of the second three-way valve 3 is closed because the first port 301 and the third port 303 are selected to be in communication with the second port 3 of the second three-way valve 3, and the second port 302 of the second three-way valve 3 is also closed because the second three-way valve 3 is selected to be in communication with the second port of the third through seventh three-way valves 4 through 8, the air pressure is maintained unchanged at this time, and the finger stops buckling.

In the present embodiment, the two-way valve 17 is a relief valve from a functional point of view. The two-way valve 17 is also an electromagnetic valve, the two-way valve 17 is a two-position two-way valve and comprises two ports, the two ports are conducted or are not conducted, and before the glove is buckled, the two-way valve 17 is used for decompressing an air outlet channel of the second port 302 of the second three-way valve 3, so that abrupt changes of the glove are reduced. Specifically, when the finger is controlled to extend from buckling, the first three-way valve 2 and the second three-way valve 3 are controlled to be powered off, and then the corresponding third three-way valve 4 to the seventh three-way valve 8 are controlled to be powered off; when the fingers are controlled to extend to bend, the first three-way valve 2 and the second three-way valve 3 are controlled to be electrified firstly, at the moment, the third three-way valve 4 to the seventh three-way valve 8 cannot be directly controlled to be electrified, because the air pressure in the air passage of the rehabilitation glove is suddenly changed, the fingers are suddenly changed and are not slowly changed, the two-way valve 17 is required to be opened for pressure relief, for example, in order to bend the fingers from the thumb, the ring finger and the little finger which are fully extended, the first three-way valve 2 and the second three-way valve 3 are controlled to be electrified firstly, the air pump 1 is required to inflate the air passage, then the two-way valve 17 is electrified for pressure relief, the pressure relief time is 0.5S, then the two-way valve 17 is powered off for recovering the pressure, and the three-way valve 4, the sixth three-way valve 7 and the seventh three-way valve 8 are electrified at the same time when the two-way valve 17 is powered off, and corresponding actions can be completed. Since the air pressure at the beginning instant when the third three-way valve 4, the sixth three-way valve 7 and the seventh three-way valve 8 are inflated at this time is the pressure of the external atmosphere, the glove will not be suddenly changed, and if the pressure is not released, the inflated pressure will be much greater than the atmospheric pressure at this time, which will cause the glove to be suddenly changed.

In this embodiment, as shown in fig. 1, the number of the check valves 18 is 10, and one check valve 18 is provided between the other five ports of the first six-way joint 9 and the first ports of the third three-way valve 4, the fourth three-way valve 5, the fifth three-way valve 6, the sixth three-way valve 7 and the seventh three-way valve 8, respectively, to allow only gas to flow from the third three-way valve 4, the fourth three-way valve 5, the fifth three-way valve 6, the sixth three-way valve 7 and the seventh three-way valve 7 to the first six-way joint 9. One check valve 18 is provided between the other five ports of the second six-way joint 10 and the second ports of the third three-way valve 4, the fourth three-way valve 5, the fifth three-way valve 6, the sixth three-way valve 7 and the seventh three-way valve 8, respectively, the check valve 18 allowing only gas to flow from the second six-way joint 10 to the third three-way valve 4, the fourth three-way valve 5, the fifth three-way valve 6, the sixth three-way valve 7 and the seventh three-way valve 8.

Further, the check valve 18 allows the air pump 1 to maintain the glove pressure (positive or negative) without inflation or deflation, that is, when one finger is flexed and extended and the second finger is flexed and extended, the check valve 18 allows the ongoing movement of the second finger to not affect the state of the first finger. For example, the check valve 18 may allow the little finger to stop buckling from straightening to buckling, and to bend halfway, and then the ring finger to fully buckle, i.e., the little finger may remain in the current state unaffected by the other. This is because when the small finger flexes, the first three-way valve 2 and the second three-way valve 3 control the system to inflate, the seventh three-way valve 8 controls the third port and the second port to be conducted for inflation, when the small finger flexes to half, the third port of the seventh three-way valve 8 is controlled to be conducted with the first port, because the first port of the seventh three-way valve 8 is connected with a pumping one-way valve 18, it is impossible to inflate the small finger, and the first port of the seventh three-way valve 8 is connected with the second port 202 of the first three-way valve 2 through the first six-way joint 9, because at this time, the first three-way valve 2 is selectively conducted with the first port 201 and the third port 203, and the air passage connected with the first port of the seventh three-way valve 8 is completely closed, so that the third port of the seventh three-way valve 8, that is, the air pressure in the small finger glove, can be kept at a constant value, thereby maintaining the current state.

Further, the two-way valve 17 may be opened for multiple times, for example, when the glove is in an open and straightened state, the two-way valve 17 needs to be controlled to release pressure first when the glove is in a stretched state, the little finger needs to be flexed, then the two-way valve 17 needs to be controlled to release pressure once when the ring finger needs to be flexed, the ring finger does not need to be flexed normally, and the little finger does not need to release pressure when the two-way valve 17 releases pressure, because the two-way valve 17 is arranged in front of the one-way valve 18, and the pressure of the little finger can keep the current state. There is no need to switch between the three-way valves, since the presence of the non-return valve 13 ensures the pressure.

In this embodiment, the rotation speed of the brushless motor of the air pump is adjusted by PWM, so as to adjust the air flow of the air pump 1, thereby controlling the movement speed of the glove, and simultaneously, the real-time rotation speed of the air pump 1 can be fed back, and in the process of buckling or straightening one finger after another, the low-speed operation of the air pump 1 can be controlled, and when five fingers are controlled to buckle or stretch simultaneously, the high-speed operation control speed of the air pump 1 can be controlled, so that the same movement speed can be achieved no matter when the five fingers are controlled separately or together.

Further, when the air pump 1 moves at a low speed, the fingers can be slowly buckled at a low speed, and then the air pump 1 can be accelerated to increase the pressure when buckling to a certain extent, because the air pump 1 is always operated at a low speed at the last time, that is, when the buckling amplitude of the fingers is larger, the pressure is slowly increased, the pressure is smaller, the time required for pressurizing to a certain pressure is longer, so that the air pump 1 can not buckle to extend or buckle for too long when moving to a set state, and therefore, the pressure can be quickly increased when the air pump 1 is accelerated, and the glove can quickly reach the set state.

The finger-separating pneumatic rehabilitation glove device adopts air path driving, adopts the glove made of flexible materials, and simultaneously, the pneumatic hose is additionally arranged on the glove, thereby reducing uncomfortable feeling in the wearing process. The glove can help a patient to conduct buckling movement and stretching movement of the hand, in addition, each finger of the glove is provided with an independent air passage, and five fingers share five independent air passages, so that each finger can stretch independently and buckle independently, single-finger single control of the finger-dividing pneumatic rehabilitation glove is achieved, rehabilitation time is effectively shortened, and recovery of hand functions is facilitated.

The foregoing is a further detailed description of the utility model in connection with the preferred embodiments, and it is not intended that the utility model be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the utility model, and these should be considered to be within the scope of the utility model.
