Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation equipment, and in particular to an exercise device for promoting tactile recovery. Background Art

[0002] Cerebral infarction is also called ischemic stroke, and Chinese medicine calls it stroke or apoplexy. This disease is caused by various reasons that lead to blood supply disorders in the local brain tissue area, resulting in ischemic hypoxic lesions and necrosis of brain tissue, and then produce clinically corresponding neurological dysfunction. Cerebral infarction is divided into major types such as cerebral thrombosis, cerebral embolism and lacunar cerebral infarction based on different pathogenesis.

[0003] The disability rate of cerebral infarction is very high, and rehabilitation training is particularly important. Rehabilitation training is generally divided into two types: limb function training and language function training. Among them, limb function training directly affects the patient's self-care ability, and the degree of recovery of limb function can directly affect the patient's quality of life and the patient's family burden;

[0004] Limb function training mainly includes walking training and object-grabbing training. During the training process, many patients show a state of "fear" because they cannot feel the objects being touched due to the loss of tactile sensation in their extremities caused by cerebral infarction. The people who take care of and assist in the treatment are usually the patients' family members, who can easily interpret the patients' "fear" as "resistance", which will affect the emotional expression of the patients' family members towards the patients. The negative emotional expression received by the patients will further aggravate the psychological trauma caused by the disease, which is not conducive to rehabilitation treatment.

[0005] Therefore, the restoration of tactile sensation in the extremities is very important in the rehabilitation treatment process. The restoration of tactile sensation in the extremities usually includes the hands and feet. The restoration of tactile sensation in the hands is beneficial to the patient's perception of picking up objects, that is, it is beneficial to the rehabilitation exercise of the upper limbs. The restoration of tactile sensation in the feet is beneficial to the patient's perception of stepping when walking, that is, it is beneficial to the rehabilitation exercise of the lower limbs.

[0052] See also Figure 1-10 , the present invention provides a technical solution: an exercise device for promoting tactile recovery, comprising a finger sleeve for wrapping a patient's finger, the finger sleeve comprising a plurality of hollow sleeve rings 1, and the plurality of hollow sleeve rings 1 overlap to form a tubular structure;

[0053] The hollow collar 1 is provided with a filling port 2 and a discharge port 3 connected to the interior of the hollow collar 1;

[0054] It also includes a filling pipe 4 and a discharge pipe 5, wherein the plurality of filling ports 2 are sequentially connected to the filling pipe 4, and the plurality of discharge ports 3 are sequentially connected to the discharge pipe 5;

[0055] One end of the filling pipe 4 is an inlet end, and the other end is an outlet end, and the outlet end is connected to a first pressure valve 6; one end of the discharge pipe 5 is an inlet end, and the other end is an outlet end, and the inlet end is provided with a receiving chamber 7, the inlet of the first pressure valve 6 is connected to the end of the filling pipe 4, and the outlet is connected to the side of the receiving chamber 7 facing away from the discharge pipe 5 through a pipeline;

[0056] A movable tube 8 is slidably fitted inside the discharge pipe 5, and the outer wall of the movable tube 8 is sealed with the inner wall of the discharge pipe 5, and a plurality of guide holes 9 corresponding to the plurality of discharge ports 3 are opened on the movable tube 8, one end of the movable tube 8 is a closed structure, and is inserted into the accommodating cavity 7 and sealed with the accommodating cavity 7, and a first elastic support member 10 is provided in the accommodating cavity 7, and when the first elastic support member 10 is in a freely extended state, the plurality of guide holes 9 are staggered with the plurality of discharge ports 3.

[0057] The filling pipe 4 is connected to a plurality of filling ports 2, and a first pressure valve 6 is arranged at the outlet end thereof, so that the outlet end is in a closed structure when no fluid is introduced, and the inlet end can be connected to a fluid source, and the fluid can be any one of gas or liquid. In this embodiment, the fluid is preferably water;

[0058] When water is introduced from the inlet end of the filling pipe 4, the water flow will enter the multiple hollow collars 1. The hollow collars 1 can be made of elastic materials such as rubber or silicone. After being filled with water, they will expand. When the internal pressure increases to the opening threshold of the first pressure valve 6, the first pressure valve 6 will open, and water will pass through the pipeline into the accommodating cavity 7 at the inlet end of the discharge pipe 5, pushing the movable pipe 8 to move in the discharge pipe 5. When the movable pipe 8 moves to the point where the guide hole 9 is opposite to the discharge port 3, the multiple hollow collars 1 will be connected to the movable pipe 8, and the water therein will be discharged by the movable pipe 8. The pipe 8 is discharged outwards. After the discharge, the pressure in the hollow collar 1 and the filling pipe 4 is reduced, the first pressure valve 6 will be closed, and the thrust on the movable pipe 8 will be cancelled. The movable pipe 8 will be reset under the action of the first elastic support member 10, so that the guide hole 9 and the discharge port 3 are restored to the staggered state. When water continues to flow into the filling pipe 4, the internal pressure can push the first pressure valve 6 to open and the first pressure valve 6 to close after the pressure is released, so that the movable pipe 8 is in a state of continuous reciprocating movement in the discharge pipe 5, so that the multiple hollow collars 1 are repeatedly expanded and contracted.

[0059] When in use, the finger sleeve is first put on the patient's finger, and then the water source is connected. During the continuous flow of the water source, the multiple hollow sleeve rings 1 can be cyclically expanded and contracted synchronously to achieve squeezing and massaging the patient's finger, thereby reducing the workload of the nursing staff during the patient's rehabilitation process;

[0060] There may be multiple finger sleeves, and the inlet ends of the multiple filling pipes 4 are connected in parallel.

[0061] In this embodiment, a second pressure valve 11 is connected in series between two adjacent filling ports 2 .

[0062] The inlets of two adjacent hollow collars 1 are isolated by the second pressure valve 11, that is, a hollow collar 1 facing the inlet end of the filling pipe 4 is filled with water first, and after the internal pressure of the hollow collar 1 reaches the opening threshold of the second pressure valve 11, the water flows into an adjacent hollow collar 1 through the second pressure valve 11, so that the filling of multiple hollow collars 1 is carried out in sequence, and when a hollow collar 1 located at the filling port 2 far away from the filling pipe 4 is filled with water, the first pressure valve 6 is triggered by pressure, and the water is poured into the discharge pipe 5 by opening the first pressure valve 6 to push the movable pipe 8 to move, so that the multiple hollow collars 1 are depressurized synchronously, which can simulate the manual massage method of medical staff.

[0063] In this embodiment, the second pressure valve 11 includes a valve chamber 12 and a valve core 13 disposed in the valve chamber 12. A partition 14 extending upward is disposed at the bottom of the inner side of the valve chamber 12, and the partition 14 divides the interior of the valve chamber 12 into two chambers, and the two chambers are respectively connected to two adjacent filling ports 2.

[0064] The valve core 13 is located above the partition 14, and the side wall of the valve core 13 is sealed with the inner wall of the valve chamber 12. A second elastic support member 15 is provided between the top surface of the valve core 13 and the top surface of the valve chamber 12. When the second elastic support member 15 is in a freely extended state, the bottom surface of the valve core 13 is sealed with the top edge of the partition 14.

[0065] The first pressure valve 6 and the second pressure valve 11 have the same structure. One chamber in the valve chamber 12 of the second pressure valve 11 is connected to the outlet end of the filling pipe 4, and the other chamber is connected to the side of the accommodating chamber 7 facing away from the discharge pipe 5 through a pipeline.

[0066] The valve chamber 12 is divided into two chambers by a partition 14. The two chambers are divided into a first chamber on the side of the filling port 2 of the filling pipe 4 and a second chamber on the drainage end of the filling port 2. The first chamber is connected to the water source or the second chamber of the previous valve chamber 12. When the first chamber is filled with water, the valve core 13 will be pushed to overcome the elastic support force of the second elastic support member 15 and move upward. When the valve core 13 moves upward, water will flow from the first chamber into the second chamber, and then fill the next hollow collar 1 with water or flow to the discharge pipe 5.

[0067] The second elastic support member 15 can be a spring, and the top of the valve chamber 12 can be an open structure, and a sealing cover is provided to close the opening. The sealing cover is connected to the valve chamber 12 by threaded fitting, and the elastic force of the second elastic support member 15 can be adjusted by rotation to adjust the pressure applied to the valve core 13, thereby adjusting the pressure required to push the valve core 13 upward. The expansion degree of the hollow collar 1 can be adjusted according to the thickness of the patient's fingers and the bearing capacity.

[0068] In this embodiment, the finger sleeve outer sleeve is provided with a shaping tube 16 , and annular baffles 17 are provided on both sides of the hollow sleeve ring 1 , and the outer edges of the annular baffles 17 are fixedly connected to the shaping tube 16 .

[0069] The shaping tube 16 serves as a limiting structure for the outward expansion of the hollow collar 1, and the annular baffle 17 serves as a limiting structure for the expansion of the hollow collar 1 on both sides, so that the hollow collar 1 can only expand inward, and the expansion and extrusion direction of the hollow collar 1 is limited, thereby avoiding interference problems caused by the expansion of two adjacent hollow collars 1, and improving the extrusion effect on the patient's fingers through inward directional expansion.

[0070] In this embodiment, it also includes a palm support plate 18 and a finger support plate 19 for mounting the finger sleeve;

[0071] A semicircular slot 20 is formed on one side of the top surface of the palm support plate 18, and a circular clip 21 is connected to one end of the finger support plate 19, and the circular clip 21 is rotatably matched with the semicircular slot 20;

[0072] The bottom surface of the circular clamping plate 21 is connected with a support shaft 22, and the support shaft 22 passes downward through the palm support plate 18 and rotates with the palm support plate 18;

[0073] The bottom surface of the palm support plate 18 is provided with a driving assembly, and the driving assembly includes a driving gear 23 and a driven gear 24. A transmission part is provided between the driving gear 23 and the driven gear 24, and the transmission part intermittently drives the driven gear 24 to rotate;

[0074] A driving motor 26 is fixedly mounted on the palm support plate 18, and the output shaft of the driving motor 26 is centrally connected to the driving gear 23;

[0075] The driven gear 24 is coaxially matched with a transmission wheel 27, and a transmission belt 28 is arranged between the transmission wheel 27 and the support shaft 22;

[0076] The driven gear 24 is centrally rotatably matched with a second axle 31 . The second axle 31 is fixedly connected to the palm support plate 18 . An elastic reset member is disposed between the driven gear 24 and the second axle 31 .

[0077] The driving motor 26 is used to drive the driving gear 23 to rotate. The driven gear 24 is connected to the driving gear 23 through the transmission part. When the driving gear 23 rotates, the driven gear 24 is intermittently driven by the transmission part to rotate around the second wheel shaft 31, thereby driving the transmission wheel 27 to rotate intermittently. When the transmission wheel 27 rotates intermittently, it drives the support shaft 22 to rotate intermittently through the transmission belt 28, and finally drives the finger support plate 19 to rotate intermittently.

[0078] Among them, the intermittent rotation of the driven gear 24 can be obtained by intermittent meshing, that is, there are two states of meshing transmission and meshing separation in a single rotation cycle. The driven gear 24 rotates during meshing transmission, and stops rotating during meshing separation. The driven gear 24 is connected to the second wheel shaft 31 through an elastic reset member. When the driven gear 24 rotates, the elastic reset member will be stretched or compressed, so that the elastic reset member is in an elastic force storage state. When the driven gear 24 stops rotating, the elastic reset member can be used to push the driven gear 24 in the opposite direction to drive the support shaft 22 to rotate back and forth continuously, so that the finger support plate 19 can swing with the support shaft 22 as the axis to move the patient's fingers to improve the massage effect.

[0079] In this embodiment, the transmission part is an intermediate gear 25, the center of which is fixedly connected to a first axle 30, and is rotatably matched with the palm support plate 18 through the first axle 30. The intermediate gear 25 includes a first half gear and a second half gear that are overlapped. The wheel surfaces of the first half gear and the second half gear are combined to form a complete gear that is continuously meshed with the driving gear 23, and the driven gear 24 is meshed with the first half gear or the second half gear.

[0080] The intermediate gear 25 is composed of a first half gear and a second half gear, the first half gear and the second half gear overlap, and the wheel surfaces of the half gear and the second half gear are combined to form a complete gear that continuously meshes with the driving gear 23, that is, the first half gear and the second half gear both have a toothed surface and a smooth circular surface, and the toothed surface and the smooth circular surface of the first half gear are respectively opposite to the toothed surface and the smooth circular surface of the second half gear. When the driving gear 23 rotates, the intermediate gear 25 can be driven to rotate continuously, while the driven gear 24 is only meshed with the first half gear or the second half gear. When meshed with the toothed surface, it will receive the power of the driving gear 23 and rotate, and when opposite to the smooth circular surface, it stops rotating and is pushed in the opposite direction to rotate under the action of the elastic reset member.

[0081] In this embodiment, the elastic return member is a return coil spring 29 , one end of which is connected to the wheel axle, and the other end of which is connected to the driven gear 24 .

[0082] When the driven gear 24 is meshed with the toothed surface of the first half gear or the second half gear, it will rotate under the power drive of the driving gear 23, and the rotation will cause the reset spring 29 to contract or expand, so that the reset spring 29 is in an elastic force storage state. When the driven gear 24 is opposite to the smooth circular surface meshed with the first half gear or the second half gear, it will rotate in the opposite direction under the elastic reset push of the reset spring 29, so as to realize the intermittent reciprocating rotation of the driven gear 24, and then drive the finger support plate 19 to swing back and forth with the support shaft 22 as the axis.

[0083] In this embodiment, a fluid supply component is also included. The fluid supply component is connected to the inlet end of the filling pipe 4 and is used to introduce fluid into the filling pipe 4.

[0084] The supply component may be a water pump connected to a water source or a water storage container with output pressure, which can pressurize water and pass it into the filling pipe 4.

[0085] In this embodiment, a flow conversion component is provided between the fluid supply component and the inlet end of the filling pipe 4, and the flow conversion component includes a shell 32 and a runner 33 provided in the shell 32. A first connecting pipe 34 is connected to the center of the bottom of the shell 32. The first connecting pipe 34 is connected to the inlet end of the filling pipe 4 through a pipeline. Two second connecting pipes 35 are symmetrically provided on the side wall of the shell 32.

[0086] The rotating wheel 33 is rotatably fitted in the housing 32. The rotating wheel 33 is semicircular. The outer circumferential surface of the rotating wheel 33 is sealed with the inner wall of the housing 32, and a semicircular cavity communicating with the first connecting pipe 34 is formed in the housing 32.

[0087] The first wheel shaft 30 extends into the housing 32 and is connected to the center of the rotating wheel 33 .

[0088] The first wheel axle 30 is connected to the center of the rotating wheel 33, so that the rotating wheel 33 can rotate synchronously with the intermediate gear 25. During the rotation, the two second connecting pipes 35 will be periodically closed or opened. The two second connecting pipes 35 can be connected to two supply components respectively. The two supply components can respectively introduce cold water and hot water into the shell 32. The two second connecting pipes 35 are alternately opened and closed, so that the first connecting pipe 34 discharges cold water or hot water alternately, and then the water introduced into the filling pipe 4 is alternately cold and hot, and finally the water entering the hollow collar 1 is alternately cold and hot, thereby improving the stimulation effect on the patient's finger area.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
