Description

Technical Field

[0001] This invention relates to the field of pneumatic finger rehabilitation, and in particular to a pneumatic finger rehabilitation device with hemostasis detection. Background Technology

[0002] Hand and finger dysfunction is common in patients with stroke hemiplegia, hand tendon injuries, joint stiffness, and nerve damage. These patients often experience weakness in finger flexion and extension, limited joint movement, and muscle atrophy. Long-term, regular passive flexion and extension training, along with hand care, is necessary to promote the recovery of finger motor function and peripheral circulation. Pneumatic finger rehabilitation devices, with their advantages of flexible actuation, high adaptability, high safety, and low cost, are widely used in home and medical institution finger rehabilitation training scenarios. They use pneumatic airbags to drive the fingers to perform passive flexion and extension movements, replacing traditional manual rehabilitation methods, effectively reducing the workload of rehabilitation personnel and improving the convenience of rehabilitation training.

[0003] Existing pneumatic finger rehabilitation devices mostly adopt an integral airbag structure with a single air circuit control method, resulting in numerous defects in practical use and seriously affecting the rehabilitation training effect and safety. First, the pneumatic drive structure of existing devices lacks segmented independent control design, and the airbag inflation deformation mode is fixed, resulting in a single and fixed overall finger movement angle. This makes it impossible to adjust the flexion and extension angles according to different rehabilitation stages and different degrees of functional impairment of different fingers, leading to extremely poor adaptability. At the same time, the devices cannot achieve independent drive and individual movement of each finger joint; they can only drive the finger as a whole to complete synchronous flexion and extension movements. They cannot provide precise single-joint rehabilitation training for the differentiated damage of the metacarpophalangeal joints, proximal interphalangeal joints, and distal interphalangeal joints of patients. They are difficult to conform to the natural segmented movement mechanism of the human finger, resulting in low precision in rehabilitation training and failing to meet personalized and step-by-step rehabilitation needs. Furthermore, different patients have different finger and palm sizes, and existing pneumatic finger rehabilitation devices cannot be flexibly adjusted to suit different patients.

[0004] Secondly, existing pneumatic finger rehabilitation devices lack hand blood flow monitoring capabilities and have inadequate safety mechanisms. These devices rely solely on fixed air pressure parameters to complete cyclic flexion and extension training, failing to monitor blood flow in the fingertips in real time. During continuous pressure application and flexion / extension training, the airbag can easily overcompress the finger's soft tissues and compress blood vessels, thus blocking peripheral blood circulation and causing problems such as insufficient local blood supply, bruising, and numbness. Prolonged training can easily lead to ischemic damage to the fingers, not only failing to achieve good rehabilitation results but also potentially worsening the patient's hand discomfort, posing a significant safety hazard.

[0005] Furthermore, existing pneumatic finger rehabilitation devices are relatively simple in function, only providing passive finger flexion and extension training without integrating hand massage auxiliary structures. During rehabilitation training, they can only achieve joint movement correction, failing to provide gentle massage and relaxation for finger muscles and meridians. This makes it difficult to alleviate finger muscle stiffness and spasms, promote peripheral blood circulation in the hands, or relieve muscle fatigue after training. They lack an integrated rehabilitation function combining exercise training and relaxation care, resulting in a limited overall rehabilitation effect due to their singular rehabilitation dimensions. Therefore, a pneumatic finger rehabilitation device with hemostasis detection is proposed. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a pneumatic finger rehabilitation device with hemostasis detection, which solves the problems of existing pneumatic finger rehabilitation devices, such as non-adjustable angle, inability to move joints independently, lack of peripheral blood flow monitoring, lack of massage function, insufficient rehabilitation safety and functionality, and poor wearability.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows:

[0008] A pneumatic finger rehabilitation device with hemostasis detection includes a controller and a palm sleeve. Each palm sleeve has finger sleeves corresponding to the five fingers. The inner end of each finger sleeve is fitted with a photoelectric pulse oximeter. Each finger sleeve has a flexible slot strip connected to the back of the hand. The palm sleeve has a fixing seat installed on the back of the hand corresponding to each finger sleeve. Several flexible airbags and sliding boxes are sequentially connected to the fixing seats facing the end of the finger sleeves. The sliding boxes have piston plates sealed and slidably fitted on both sides. A fixing tube is provided between the piston plates on both sides, penetrating the surface of the sliding box and installed on the inner wall of the sliding box. Each sliding box has an air hole between it and the flexible airbag fitted on it.

[0009] The inner walls on both sides of the sliding box are symmetrically equipped with positioning rods that cooperate with the flexible slot strips. A sleeve is connected to the sliding box. An electrical conduit connects the fixed seat to the sliding box and the sleeve on the same finger sleeve. A locking assembly is provided inside the sliding box. The locking assembly is used to drive the positioning rods to be inserted and limited by the flexible slot strips when the piston plates on both sides slide away from each other. An adjustment assembly is provided inside the sleeve. The adjustment assembly is used to adjust the air supply from the fixed tube to the flexible airbag inside or outside the sliding box. An airbag ring is fitted on the outside of the sleeve. A pressing assembly is also provided inside the sleeve. The pressing assembly is used to scrape and supply air into the airbag ring to achieve finger massage.

[0010] Preferably, the palm sleeve has matching Velcro on both sides, and a male button is installed on the back of the palm sleeve corresponding to the base of each finger sleeve. A female button that engages with the male button is installed on the side of the fixing base near the palm sleeve. An electrical cable conduit for connecting to the controller is connected to the fixing base.

[0011] Preferably, the piston plates on both sides are connected by an air tube 1, which slides in a sealed and fitted manner within an air hole 1 on the corresponding side. A soft air tube 2 with redundant length is connected between the fixed tube and the air tube 1 on the piston plate.

[0012] Preferably, the flexible airbag is fixed near the flexible slot strip by Velcro, and multiple positioning holes are equally spaced through both sides of the flexible slot strip, with each positioning rod being inserted into the corresponding positioning hole.

[0013] Preferably, the positioning assembly includes a guide rod and a sleeve plate. The guide rod is connected to the upper and lower ends of the piston plates on both sides of the slide box, which are far apart from each other. The sleeve plate is symmetrically slidably fitted on the front and rear ends of each guide rod. The positioning rod is connected to the upper and lower ends of the sleeve plates symmetrically arranged at both ends of the guide rod, which are far apart from each other. Rotary plates are rotatably connected between the piston plates on both sides and the sleeve plates at both ends of the guide rod.

[0014] Preferably, the surface of the sliding box has a sliding hole through the inner wall for the positioning rod to slide through its inner and outer sides, and each of the sleeve plates is connected to the inner wall of its respective side sliding box by a spring sleeved on the outside of the guide rod.

[0015] Preferably, the adjusting assembly includes a sliding tube, a sleeve, a micro electric screw, and two air holes. The sliding tube is slidably sleeved inside the fixed tube, and the lower end of the sliding tube extends into the sleeve. The sleeve is radially fitted onto both sides of the sliding tube at one end inside the sleeve. The micro electric screw is radially installed on both sides of the inner wall of the sleeve. The sleeve is threaded onto the outer side of the micro electric screw on each side. The two air holes are radially opened along the sliding tube and are respectively connected to the two air holes on both sides.

[0016] Preferably, the upper end of the sliding tube is sealed and the lower end is open, while both the upper and lower ends of the fixed tube are open.

[0017] Preferably, the pressing assembly includes an air hole three, a sliding rod, a sealing block, and a lever block. The air hole three is opened on both radial sides of the sleeve. The air bladder ring is in cooperation with and passes through the air hole three. The sliding rod is connected to both radial sides of the inner wall of the sleeve. The sealing block is slidably sleeved on the outside of the sliding rod and slides in close contact with the inner wall of the sleeve, and seals the air hole three. A spring two sleeved on the outside of the sliding rod is connected between the lower end of the sealing block and the lower inner wall of the sleeve. Lever blocks that abut against the upper end of the sealing block are connected to both radial sides of the sliding tube.

[0018] Preferably, the airbag ring is connected to an outer cylinder that is sealed and sleeved on the outside of the sleeve. A rotating cylinder that is threaded onto the outside of the sleeve is rotatably mounted on the outer cylinder. Grooves are provided on both sides of the outer cylinder, and the electrical conduit clamp is sleeved in the groove.

[0019] The beneficial effects of this invention are:

[0020] 1. The technical solution of this invention controls the piston plates on both sides of each slide box to move away from each other, thereby driving the rotating plate to rotate and pushing the sleeve plates at both ends of the guide rods on both sides of the slide box to move away from each other. This causes the guide rods to engage with the positioning holes on the side of the flexible slot strip, flexibly adjusting the position of the slide box on the flexible slot strip. This allows patients with different finger lengths to wear the device comfortably and effectively by adjusting the distance between adjacent slide boxes when using it on different patients and different fingers. At the same time, the fixing seat is fastened by the female button and the male button on the back of the hand sleeve, allowing the fixing seat, slide box and the flexible airbag between them to be flexibly removed from the hand sleeve, improving the flexibility of use. At the same time, each slide box and the fixing seat are connected by an electrical conduit to ensure air supply and ventilation and circuit control. The electrical cable conduits on the fixing seats on each finger can be centrally connected to the controller to realize the control of the device on each finger, ensuring the universality, comfort and flexibility of use.

[0021] 2. The technical solution of this invention uses a micro electric screw to drive the sleeve and sliding tube to slide into the sliding box inside the fixed tube until the second air hole on the sliding tube leaks out of the fixed tube. At this time, when the fixed tube supplies air, the gas will enter between the piston plates on both sides, which can push the piston plates on both sides away from each other, so as to realize the sliding box being clamped on the flexible slot strip. Then, the sliding tube is controlled to slide into the sleeve until the second air hole slides into the fixed tube. At this time, the gas will not be supplied into the sliding box. After the second air hole is controlled to be connected to the second air pipe on both sides of the fixed tube, the first air pipe on the piston plates on both sides will also be connected to the first air hole because the piston plates on both sides are away from each other. In this way, the supplied gas will enter the flexible air bag through the second air pipe and the first air pipe to pneumatically assist the flexion of the finger. Since each micro electric screw can be independently controlled by the controller, it is also possible to assist the flexion of a single joint on the finger, which improves the flexibility of use.

[0022] 3. The technical solution of this invention uses a miniature electric screw to further drive the sliding tube into the sleeve. At this time, when the second air hole corresponds to the second air tube on both sides of the fixed tube, the state of the push block and the sealing blocks on both sides will gradually change to the push block pushing the sealing blocks away from the sliding box and opening the third air hole. In this way, the third air hole and the air bag ring form a passage, and the second air hole is no longer connected to the second air tube. This allows for independent air supply and exhaust of the air bag ring, so as to achieve the pressing of the fingers by repeatedly inflating and deflating the air bag ring. Combined with the photoelectric pulse oxygen sensor to detect the blood flow oxygen supply of the fingers, it can achieve auxiliary massage of the fingers, avoid finger ischemia and hypoxia, and ensure better rehabilitation effect.

[0033] The following will be combined with the appendix Figure 1 To be continued Figure 8 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: As Figures 1-8As shown, the present invention discloses a pneumatic finger rehabilitation device with hemostasis detection, including a controller 1 and a palm sleeve 2. The palm sleeve 2 is connected to finger sleeves 3 corresponding to the five fingers respectively. The inner end of the finger sleeve 3 is fitted with a pair of photoelectric pulse oxygenation sensors 6. Each finger sleeve 3 is connected to a flexible slot strip 7 facing the back of the hand. The palm sleeve 2 is equipped with a fixing seat 9 corresponding to each finger sleeve 3 on the back of the hand. The fixing seat 9 is connected to a plurality of flexible airbags 12 and a sliding box 13 in sequence facing the end of the finger sleeve 3. The sliding box 13 is sealed and slidably fitted with piston plates 15 on both sides. A fixing tube 23 is provided between the piston plates 15 on both sides, penetrating the surface of the sliding box 13 and installed on the inner wall of the sliding box 13. Each sliding box 13 and the flexible airbag 12 fitted thereon are provided with an air hole 22.

[0035] The sliding box 13 has symmetrically sliding positioning rods 18 at both ends of its inner walls, which are inserted into the flexible slot strips 7. A sleeve 26 is connected to the sliding box 13. An electrical conduit 14 is connected in series between the fixed seat 9 and the sliding box 13 and sleeve 26 on the same finger sleeve 3. A locking component is provided inside the sliding box 13. The locking component is used to drive the positioning rods 18 and the flexible slot strips 7 to be inserted and limited when the piston plates 15 on both sides slide away from each other. An adjustment component is provided inside the sleeve 26. The adjustment component is used to adjust the air supply from the fixed tube 23 to the flexible airbag 12 inside or outside the sliding box 13. An airbag ring 33 is fitted on the outside of the sleeve 26. A pressing component is also provided inside the sleeve 26. The pressing component is used to scrape and supply air into the airbag ring 33 to achieve finger massage.

[0036] The flexible slot strip 7 is made of flexible plastic.

[0037] The palm sleeve 2 has matching Velcro 4 on both sides. On the back of the palm sleeve 2, a male button 5 is installed at the base of each finger sleeve 3. The fixing base 9 has a female button 10 that matches the male button 5 on the side near the palm sleeve 2. The fixing base 9 is connected to the electrical cable tube 11 that connects to the controller 1, which makes it easy to wear the palm sleeve 2 and also easy to disassemble and assemble the fixing base 9. It also allows for the flexible assembly and disassembly of the fixing base 9, the flexible airbag 12, and the sliding box 13 on the flexible slot strip 7, so that the fixing base 9, the flexible airbag 12, and the sliding box 13 can be flexibly assembled and disassembled on the finger sleeve 3.

[0038] The piston plates 15 on both sides are connected by an air tube 24 on the side away from each other, and the air tube 24 slides in a sealed fit within the air hole 22 on the corresponding side. A soft air tube 25 with redundant length is connected between the fixed tube 23 and the air tube 24 on the piston plate 15, so that when the piston plates 15 on both sides are away from each other, the air tube 25 can extend through the redundant length.

[0039] The flexible airbag 12 is fixed near the flexible slot strip 7 by Velcro. Multiple positioning holes 8 are equally spaced through both sides of the flexible slot strip 7. Each positioning rod 18 is inserted into the corresponding positioning hole 8 to ensure that one side of the flexible airbag 12 is fixed, which facilitates pneumatic bending control. It also facilitates the installation and removal of the sliding box 13 and position adjustment by inserting the positioning rod 18 into the positioning hole 8.

[0040] Example 2: Figures 1-8 As shown, the present invention discloses a pneumatic finger rehabilitation device with hemostasis detection. Compared with Embodiment 1, this embodiment discloses the structure of the locking component.

[0041] The positioning assembly includes a guide rod 16 and a sleeve plate 17. The guide rod 16 is connected to the upper and lower ends of the piston plates 15 on both sides of the slide box 13, which are far apart from each other. The sleeve plate 17 is symmetrically slidably fitted on the front and rear ends of the guide rod 16 on each side. The positioning rod 18 is connected to the upper and lower ends of the sleeve plate 17 symmetrically arranged at both ends of the guide rod 16, which are far apart from each other. The piston plates 15 on both sides and the sleeve plates 17 at both ends of the guide rod 16 are rotatably connected to a rotating plate 21.

[0042] The surface of the slide box 13 has a sliding hole 19 through the inner wall for the positioning rod 18 to slide through its inner and outer sides. Each sleeve plate 17 is connected to the inner wall of its respective side slide box 13 by a spring 20 sleeved on the outside of the guide rod 16. The spring 20 can assist the piston plates 15 on both sides to move closer to each other more flexibly when the fixed pipes 23 on both sides are venting.

[0043] By controlling the piston plates 15 on both sides of each slide box 13 to move away from each other, the rotating plate 21 can be driven to rotate, and the sleeve plates 17 at both ends of the guide rods 16 on both sides of the slide box 13 can be pushed away from each other. This causes the positioning rod 18 connected to the sleeve plates 17 at both ends of the guide rods 16 to pass through the sliding hole 19 and slide to the outside of the slide box 13, where it can be inserted into the positioning hole 8 on the side of the flexible slot strip 7. This allows for flexible adjustment of the position of the slide box 13 on the flexible slot strip 7, so that when different patients and different fingers use it, the distance between adjacent slide boxes 13 can be adjusted to ensure that patients with different finger lengths can wear it comfortably and effectively. Furthermore, the number of joints in each finger can be adjusted accordingly. The number of sliding boxes 13 can be flexibly arranged, usually with two sliding boxes 13 on each side of each joint. Only one side of the sliding box 13 at the fingertip is connected to the flexible airbag 12. At the same time, the fixing seat 9 can be flexibly removed from the palm sleeve 2 by the snap between the female button 10 and the male button 5 on the back of the palm sleeve 2, thereby improving the flexibility of use. Meanwhile, each sliding box 13 and the fixing seat 9 are connected by an electrical conduit 14 to ensure air supply and ventilation and circuit control. The electrical cable conduit 11 on the fixing seat 9 on each finger can be centrally connected to the controller 1 to realize the control of the device on each finger, ensuring the versatility, comfort and flexibility of use.

[0044] Example 3: Figures 1-8 As shown, the present invention discloses a pneumatic finger rehabilitation device with hemostasis detection. Compared with Embodiment 2, this embodiment discloses the structure of the adjustment component.

[0045] The adjustment assembly includes a sliding tube 27, a sleeve 28, a micro electric screw 29, and an air vent 30. The sliding tube 27 is slidably sleeved inside the fixed tube 23, and the lower end of the sliding tube 27 extends into the sleeve 26. The sleeve 28 is radially fitted onto both sides of the sliding tube 27 at one end inside the sleeve 26. The micro electric screw 29 is radially installed on both sides of the inner wall of the sleeve 26. The sleeve 28 is threaded onto the outer side of the micro electric screw 29 on each side. The air vent 30 is radially opened along the sliding tube 27 and is respectively connected to the air vent 25 on both sides.

[0046] The upper end of the sliding tube 27 is sealed, while the lower end is open. The upper and lower ends of the fixed tube 23 are both open, ensuring the smooth flow of the overall air passage.

[0047] The micro electric screw 29 operates, driving the sleeve 28 and sliding tube 27 to slide into the sliding box 13 within the fixed tube 23 until the second air hole 30 on the sliding tube 27 leaks out of the fixed tube 23. At this time, when the fixed tube 23 supplies air, the air will enter between the two piston plates 15, which can push the two piston plates 15 away from each other, so as to achieve the locking of the sliding box 13 onto the flexible slot strip 7. Then, the sliding tube 27 is controlled to slide into the sleeve 26 until the second air hole 30 slides into the fixed tube 23. At this time, the sliding box 13 will not be locked. 3. Internal air supply, and after the control air hole 20 is connected to the air pipe 25 on both sides of the fixed tube 23, the air pipe 24 on the piston plates 15 on both sides will also be connected to the air hole 22 due to the distance between them. In this way, the supplied gas will enter the flexible air bag 12 through the air pipe 25 and the air pipe 24 to pneumatically assist the flexion of the fingers. Since each micro electric screw 29 can be independently controlled by the controller 1, it is also possible to assist the flexion of a single joint on the finger, which improves the flexibility of use.

[0048] Example 4: Figures 1-8 As shown, the present invention discloses a pneumatic finger rehabilitation device with hemostasis detection. Compared with Embodiment 3, this embodiment discloses the structure of the pressing component.

[0049] The pressing assembly includes an air hole 34, a slide rod 35, a sealing block 36, and a lever 38. The air hole 34 is located on both radial sides of the sleeve 26. The airbag ring 33 is connected to the air hole 34. The slide rod 35 is connected to both radial sides of the inner wall of the sleeve 26. The sealing block 36 is slidably sleeved on the outside of the slide rod 35 and slides against the inner wall of the sleeve 26, and seals the air hole 34. A spring 37 is connected between the lower end of the sealing block 36 and the lower inner wall of the sleeve 26 and is sleeved on the outside of the slide rod 35. Lever blocks 38 are connected to both radial sides of the sliding tube 27 to abut against the upper end of the sealing block 36.

[0050] An outer cylinder 31 is connected to the airbag ring 33 and is sealed on the outside of the sleeve 26. A rotating cylinder 32 is rotatably fitted on the outer cylinder 31 and threaded onto the outside of the sleeve 26. Grooves 39 are provided on both sides of the outer cylinder 31, and the electrical tube 14 is fitted into the grooves 39. This allows the outer cylinder 31 to be sealed on the outside of the sleeve 26 by rotating the rotating cylinder 32 and threading it onto the outside of the sleeve 26. The alignment and locking of the grooves 39 and the electrical tube 14 make the airbag ring 33 and the air hole 34 connected and connected.

[0051] The micro electric screw 29 further drives the sliding tube 27 to slide into the sleeve 26. At this time, when the second air hole 30 corresponds to the second air tube 25 on both sides of the fixed tube 23, the state of the push block 38 and the two side blocking blocks 36 being in contact will gradually change to the push block 38 pushing the blocking blocks 36 away from the sliding box 13 and opening the third air hole 34. In this way, the third air hole 34 and the air bag ring 33 form a passage, and the second air hole 30 is no longer connected to the second air tube 25. This allows for independent air supply and exhaust of the air bag ring 33, so that the fingers can be pressed by the repeated inflation and deflation of the air bag ring 33. In conjunction with the photoelectric pulse oxygen sensor 6 to detect the blood flow oxygen supply to the fingers, the fingers can be massaged to avoid ischemia and hypoxia and ensure better rehabilitation results.

[0052] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
