Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically a mirror-image motion glove for hemiplegic patients. Background Technology

[0002] Mirror glove is a smart glove driven by aerodynamics. The term "mirror" means that when one glove performs a certain action, the other glove replicates that action in a mirror image. For example, if you open your left hand while wearing the first glove, the right glove will repeat the action, thus opening your right hand. For patients requiring hand rehabilitation training, this automatic fist-clenching motion of the mirror glove greatly helps them regain hand function.

[0003] Existing technology, such as Chinese Patent No. CN213697791U, discloses a mirror-shaped functional glove for hand rehabilitation training, comprising: a mirror glove, a training glove, and a main unit; wherein, a Hall sensor is installed at the palm position of the mirror glove, and the Hall sensor is electrically connected to the main unit in a pluggable manner via a signal line; at least one magnet is installed at the fingertip position of the mirror glove; the magnet approaches or contacts the Hall sensor when the mirror glove is in a clenched fist state; corrugated tubes are installed on the back of the finger sleeves of the training glove at positions corresponding to each finger joint; the corrugated tube on each finger sleeve is connected to an air hose; the air hose is pluggable connected to the main unit; the main unit controls the air hose to inflate or de-inflate according to the relative position of the magnet and the Hall sensor.

[0004] In the aforementioned existing mirror-image motion glove, when the patient uses the mirror-image glove, a sensing signal is generated and fed back to the main unit. The air pump in the main unit generates compressed air and delivers the compressed air to the bellows, causing the training glove to produce the same movements as the mirror-image glove. However, because the patient is in a state of hemiplegia, the wrist may not have the strength to straighten the palm. Thus, when the training glove moves, such as making a fist, the patient's palm will droop, resulting in an improper fist-making action. The patient cannot perceive whether their palm is drooping. Therefore, if the training action is not standardized, over time, the patient will not receive correct training, will not achieve the training effect, and may affect the patient's future rehabilitation. Summary of the Invention

[0005] The purpose of this invention is to provide a mirror-image motion glove for hemiplegic patients to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mirror-image exercise glove for hemiplegic patients, comprising a mirror-image glove and a training glove connected to a main unit, wherein the training glove is equipped with a corrugated tube connected to an air pump inside the main unit, and further comprising:

[0010] A swing rod is hinged to the collar, and a pad is provided at one end of the swing rod extending toward the training glove. The upper surface of the pad is in contact with the lower surface of the training glove.

[0011] A connecting part used to disconnect the connection seat from the air pump inside the main unit when the swing arm swings downwards.

[0012] Preferably, the pad is made of rubber.

[0013] Preferably, the connecting portion includes:

[0014] A first connecting pipe is provided on the outer wall of the connecting seat, and a sealing seat is connected to the first connecting pipe. The sealing seat has a connecting cavity that communicates with the first connecting pipe. A second connecting pipe that communicates with the connecting cavity is provided on the sealing seat. The second connecting pipe is connected to the air pump in the main unit.

[0015] A sealing plunger that engages within the communicating cavity and can slide freely up and down;

[0016] A connecting rod is coaxially connected to the sealing plunger, and the upper end of the connecting rod slides out of the top of the sealing seat;

[0017] A drive mechanism for driving the connecting rod to slide upward when the swing rod swings downward, thereby causing the sealing plunger to disconnect the connection between the first and second connecting pipes.

[0018] Preferably, the drive mechanism includes:

[0019] A connecting arm is provided at the end of the swing rod away from the training glove, and the connecting arm has a notch for the connecting rod to pass through freely;

[0020] A sliding pin is horizontally inserted through the upper end of the connecting rod, and the connecting arm is provided with a waist-shaped hole for the sliding pin to be inserted and which can slide freely horizontally.

[0021] A first spring, which is wrapped around the connecting rod and elastically abuts against the sealing plunger downwards.

[0022] Preferably, the connecting seat is provided with an overpressure protection part, the overpressure protection part comprising:

[0023] A partition is provided inside the connecting seat, which divides the interior of the connecting seat into a buffer cavity that is connected to the hollow adapter. The partition is also provided with a plurality of connecting holes that are connected to the buffer cavity.

[0024] A sliding rod is horizontally slidably inserted through the partition plate. A sealing block is provided at the end of the sliding rod away from the buffer cavity. The sealing block is provided corresponding to the opening of the first connecting pipe.

[0025] A trigger mechanism for driving the sliding rod to slide so that the sealing block closes the first connecting pipe opening.

[0026] Preferably, the triggering mechanism includes:

[0027] A fixed sleeve that is fixed to the partition plate and slidably fitted onto the sliding rod;

[0028] A baffle mounted on the sliding rod can close the communicating hole when its end face abuts against the surface of the partition.

[0029] A limiting block is fixedly connected to the end of the sliding rod away from the sealing block;

[0030] A support sleeve is coaxially connected to the baffle plate. The support sleeve is movably fitted onto the fixed sleeve. A clearance groove is coaxially provided inside the support sleeve. An inwardly turned annular protrusion is provided at the edge of the opening of the clearance groove. The outer end face of the annular protrusion abuts against the surface of the limiting block. Multiple strip grooves communicating with the clearance groove are arranged in an array along the axial direction on the outer wall of the support sleeve.

[0031] A second spring that is sleeved around the sliding rod and elastically abuts against the sealing block;

[0032] A spreading unit that can drive the support sleeve to produce an elastic spreading deformation along the radially outer side of the support sleeve when the baffle moves away from the partition.

[0033] Preferably, the spreading unit includes:

[0034] An annular protrusion is coaxially connected to the end of the fixed sleeve away from the partition plate. The outer diameter of the annular protrusion increases sequentially in the direction away from the partition plate. The annular protrusion is located in the clearance groove.

[0035] A conical groove is coaxially formed within the support sleeve and communicates with the clearance groove. The inner diameter of the conical groove increases sequentially in the direction away from the partition and is used in conjunction with the annular protrusion.

[0036] Preferably, the support sleeve is made of spring steel.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] This invention, through the design of a collar, a swing rod, and a connecting part, allows the patient's wrist to pass through the collar. When the wrist is too weak to lift the palm or the lifting range is insufficient, the patient's palm will droop, exerting downward pressure on the pad. This causes the pad to drive the swing rod downward, triggering the connecting part to activate. This disconnects the air pump in the main unit from the connecting seat, preventing the air pump in the main unit from supplying air to the bellows on the training glove. Consequently, the training glove does not move synchronously with the mirror glove, avoiding poor rehabilitation results after prolonged training due to improper wrist lifting angles, and preventing the development of incorrect rehabilitation training habits that could affect later rehabilitation.

[0039] This invention incorporates an overpressure protection feature, which automatically disconnects the continued supply of compressed air to the bellows when the air pump in the main unit has a high air pressure, thus preventing the training gloves from undergoing excessive flexion and extension, which could cause secondary damage to the patient's fingers.

[0040] This invention, by setting a support sleeve and an annular protrusion, allows compressed air to be introduced into the connecting seat. The compressed air pushes the baffle to move, which in turn moves the support sleeve. This causes the inner wall of the conical groove on the support sleeve to slide relative to the inclined surface on the annular protrusion, and drives the support sleeve to elastically expand and deform. This allows the annular protrusion to remove its restriction on the limiting block, allowing the limiting block to enter the clearance groove. It also drives the end face of the sealing block to abut against the inner wall of the connecting seat, thereby sealing the interior of the connecting seat and preventing compressed air from entering the connecting seat and then the bellows.

Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] like Figures 1-16 As shown, the present invention provides a technical solution: a mirror-image exercise glove for hemiplegic patients, comprising a mirror-image glove 1 and a training glove 3 connected to a host 2. A Hall sensor is installed at the palm position of the mirror-image glove, and the Hall sensor is electrically connected to the host via a signal line. At least one magnet is installed at the fingertip position of the mirror-image glove; when the mirror-image glove is in a clenched fist state, the magnet approaches or contacts the Hall sensor. Corrugated tubes 4 are installed on the back of the finger sleeves of the training glove at positions corresponding to each finger joint; the corrugated tubes on each finger sleeve are connected to an air hose; the air hose is detachably connected to an air pump in the host; the host controls the air hose to inflate or de-inflate according to the relative position of the magnet and the Hall sensor. The mirror-image exercise glove also includes:

[0060] A collar 6 is provided corresponding to the training glove 3. A support plate 11 is provided on the outer wall of the collar 6. The support plate 11 may be welded to the collar 6.

[0061] A hollow connecting seat 8 is located at the lower end of the support plate 11. The connecting seat 8 is connected to the air pump in the main unit 2. In addition, a support column can be welded to the bottom of the connecting seat 8. In this way, after the patient's wrist is inserted into the collar 6, the support column can provide support for the patient's arm.

[0062] A hollow adapter 5 is provided on the training glove 3. The hollow adapter 5 is connected to the corrugated pipe 4 and the connecting seat 8 through a flexible tube.

[0063] A swing rod 10 is hinged to the collar 6. A pad 9 is provided at one end of the swing rod 10 extending toward the training glove 3. The upper surface of the pad 9 is in contact with the lower surface of the training glove 3.

[0064] A connecting part that disconnects the connection between the connecting seat 8 and the air pump inside the main unit 2 when the swing arm 10 swings downwards.

[0065] In the mirror-image exercise glove for hemiplegic patients described in this invention, the patient's wrist is inserted into the loop. When the wrist is too weak to lift the palm or the lifting range is insufficient, the patient's palm will droop and exert downward pressure on the pad, causing the pad to drive the swing rod to swing downward. This triggers the action of the connecting part, thereby isolating the air pump in the main unit from the connecting seat. That is, the air pump in the main unit cannot supply air to the bellows on the training glove, so the training glove will not move synchronously with the mirror-image glove. This avoids the patient's improper wrist lifting angle leading to poor rehabilitation effect after long-term exercise, and also avoids the patient developing incorrect habits in rehabilitation training, which will affect the later rehabilitation.

[0066] like Figures 1-16 As shown, pad 9 is made of rubber.

[0067] In the mirror-shaped exercise glove for hemiplegic patients described in this invention, the pad 9 is made of rubber material so that the pad 9 will not cause squeezing pain to the patient's hand.

[0068] like Figures 1-16 As shown, the connected part includes:

[0069] A first connecting pipe 12 is provided on the outer wall of the connecting seat 8. A sealing seat 7 is connected to the first connecting pipe 12. A connecting cavity 28 is opened inside the sealing seat 7, which communicates with the first connecting pipe 12. A second connecting pipe 13 is provided on the sealing seat 7, which communicates with the connecting cavity 28. The second connecting pipe 13 is connected to the air pump in the main unit 2.

[0070] A sealing plunger 19 is fitted into the communicating cavity 28 and can slide freely up and down. The sealing plunger 19 can be made of soft rubber, and the outer diameter of the sealing plunger 19 is larger than the diameter of the first communicating hole 12 and the second communicating hole 13.

[0071] A connecting rod 17 is coaxially connected to the sealing plunger 19, and the upper end of the connecting rod 17 slides out of the top of the sealing seat 7;

[0072] A drive mechanism for driving the connecting rod 17 to slide upward when the swing rod 10 swings downward, thereby causing the sealing plunger 19 to disconnect the connection between the first connecting pipe 12 and the second connecting pipe 13.

[0073] In the mirror motion glove for hemiplegic patients described in this invention, when the patient's wrist is weak or the range of motion of the palm is insufficient, the patient's wrist and palm will bend relative to each other, causing the training glove 3 to swing downwards (the patient's palm is on the training glove, and the swinging of the wrist will cause the training glove to swing), which can drive the pad to move downwards. The downward movement of the pad will cause the swing rod 10 to swing downwards along the hinge with the collar, triggering the drive mechanism to work and causing the connecting rod 17 to move upwards. This causes the sealing plunger 19 to slide upwards in the communicating cavity 28 until the sealing plunger 19 seals the first communicating hole 12 and the second communicating hole 13, preventing the air pump pressure from being too high, which would cause the bellows to bend too much and thus cause injury to the patient's hand.

[0074] like Figures 1-16 As shown, the drive mechanism includes:

[0075] A connecting arm 14 is provided at the end of the swing rod 10 away from the training glove 3. The connecting arm 14 has a notch for the connecting rod 17 to pass through freely. The upper end of the connecting rod 17 can move freely within the notch.

[0076] A sliding pin 16 is horizontally inserted through the upper end of the connecting rod 17. The connecting arm 14 is provided with a waist-shaped hole 15 for the sliding pin 16 to be inserted and can slide freely horizontally. The length direction of the waist-shaped hole 15 is parallel to the length direction of the connecting arm 14.

[0077] A first spring 18, which is wrapped around the connecting rod 17 and elastically abuts against the sealing plunger 19 downwards.

[0078] In the mirror motion glove for hemiplegic patients described in this invention, when the swing rod 10 swings downward, it will cause the connecting arm 14 to flip upward, so that the sliding pin 16 slides in the waist-shaped hole and causes the connecting rod 17 to move upward, thereby causing the sealing plunger 19 to seal the first connecting pipe 12 and the second connecting pipe 13.

[0079] like Figures 1-16 As shown, the connecting seat 8 is provided with an overpressure protection unit, which includes:

[0080] A partition 20 is provided inside the connecting seat 8, which divides the interior of the connecting seat 8 into a buffer cavity 21 that is connected to the hollow adapter 5. The partition 20 is also provided with a plurality of connecting holes 22 that are connected to the buffer cavity 21.

[0081] A sliding rod 33 is horizontally slidably installed on the partition 20. A sealing block 26 is provided at the end of the sliding rod 33 away from the buffer cavity 21. The sealing block 26 is correspondingly provided with the opening of the first connecting pipe 12. In other words, when the sliding rod 33 moves toward the opening of the first connecting pipe 12, it will drive the sliding rod 33 to move. When it moves, the sealing block 26 gradually approaches the opening of the first connecting pipe until the end face of the sealing block 26 can be pressed tightly, thereby preventing compressed air from entering the connecting cavity 28.

[0082] A triggering mechanism for driving the sliding rod 33 to slide so that the sealing block 26 closes the opening of the first connecting pipe 12.

[0083] In the mirror motion glove for hemiplegic patients described in this invention, when the compressed air pressure delivered by the air pump of the main unit 2 is relatively high, the air pressure entering the connecting cavity is also relatively high. At this time, the sliding rod will drive the sealing plunger to slide upward in the connecting cavity, so that the sealing plunger can seal the opening of the first connecting tube.

[0084] like Figures 1-16 As shown, the triggering mechanism includes:

[0085] A fixing sleeve 34 is fixed to the partition plate 20 and slidably fitted onto the sliding rod 33. The fixing sleeve 34 may be welded to the partition plate.

[0086] The baffle 27, which is slidably fitted onto the sliding rod 33, can close the connecting hole 22 when its end face abuts against the surface of the partition 20.

[0087] A limiting block 29 is fixedly connected to the end of the sliding rod 33 away from the sealing block 26. The outer diameter of the limiting block 29 is larger than the outer diameter of the sliding rod 33.

[0088] A support sleeve 23 is coaxially connected to the baffle 27. The support sleeve 23 is movably fitted onto the fixed sleeve 34. A clearance groove 32 is coaxially provided inside the support sleeve 23. An inwardly turned annular protrusion 31 is provided at the edge of the opening of the clearance groove 32. The outer end face of the annular protrusion 31 abuts against the surface of the limiting block 29. Multiple strip grooves 24 that communicate with the clearance groove 32 are arranged in an array along the axial direction on the outer wall of the support sleeve 23. The inner diameter of the clearance groove 32 is larger than the outer diameter of the limiting block 29. When the support sleeve 23 undergoes elastic expansion deformation, the annular protrusion will also be expanded, so that the limiting state of the limiting block 29 by the annular protrusion disappears.

[0089] The second spring 25, which is wrapped around the sliding rod 33 and elastically abuts against the sealing block 26, will drive the sealing block 26 toward the opening of the first connecting pipe when the limiting state of the annular protrusion on the limiting block 29 disappears, until the end face of the sealing block 26 can close the opening of the first connecting pipe.

[0090] A spreading unit that can drive the support sleeve 23 to produce an elastic spreading deformation along the radial outer side of the support sleeve 23 when the baffle 27 moves away from the partition 20.

[0091] In the mirror motion glove for hemiplegic patients described in this invention, the air pump in the main unit 2 operates and generates compressed air. After the compressed air enters the first connecting pipe 12, it then enters the connecting seat. The compressed air pushes the baffle to move, allowing the compressed air to enter the buffer chamber 21 through the connecting hole, and then enter the hollow adapter 5 through the buffer chamber 21 to supply air to the bellows. When the compressed air pressure delivered by the air pump in the main unit 2 is large, the baffle is pushed by the compressed air to a large stroke, which can trigger the action of the opening unit, causing the opening unit to open the support sleeve 23. When the support sleeve 23 undergoes elastic opening deformation, the annular protrusion will also be opened, causing the limiting state of the annular protrusion on the limiting block 29 to disappear. When the limiting state of the annular protrusion on the limiting block 29 disappears, the second spring 25 will drive the sealing block 26 to move toward the opening of the first connecting pipe until the end face of the sealing block 26 can close the opening of the first connecting pipe.

[0092] like Figures 1-16 As shown, the expansion unit includes:

[0093] An annular protrusion 30 is coaxially connected to the end of the fixed sleeve 34 away from the partition 20. The outer diameter of the annular protrusion 30 increases sequentially in the direction away from the partition 20. The annular protrusion 30 is located in the clearance groove 32.

[0094] A conical groove 35 is coaxially formed within the support sleeve 23 and communicates with the clearance groove 32. The inner diameter of the conical groove 35 increases sequentially in the direction away from the partition plate 20 and is used in conjunction with the annular protrusion 30.

[0095] In the mirror motion glove for hemiplegic patients described in this invention, when the baffle moves away from the partition, the conical groove 35 gradually approaches the annular protrusion 30. When the pressure of the compressed air is high enough, the annular protrusion will slide relative to the inner wall of the conical groove 35, so that the support sleeve 23 can be opened.

[0096] like Figures 1-16 As shown, the support sleeve is made of spring steel.

[0097] In the mirror-shaped sports glove for hemiplegic patients described in this invention, the support sleeve is made of spring steel, which makes the elastic deformation capacity of the support sleeve greater.
