Description

Technical Field

[0001] This application relates to the technical field of medical rehabilitation devices, and in particular to an intermittent pneumatic pressure therapy device with an integrated heating module. Background Technology

[0002] The main purpose of intermittent pneumatic pressure therapy devices is to apply orderly circulatory pressure to the limb from the distal end to the proximal end by periodically inflating and deflating an air bladder wrapped around the limb, thereby promoting venous blood and lymph return, effectively preventing deep vein thrombosis and reducing limb edema. It is widely used in the clinical rehabilitation treatment of orthopedic, neurological and long-term bedridden patients.

[0003] Existing intermittent pneumatic pressure therapy devices mainly consist of three core modules: an air supply system, an air path switching system, and a control system. The air supply system typically includes an air pump and an air tank, responsible for generating and storing compressed air. The air path switching system uses multiple solenoid valves to control the flow of air between different air chambers. The control system coordinates the start and stop of the air pump and the timing of the solenoid valves via a microcomputer program, and receives user commands for pressure values, interval times, and treatment modes via an operation panel. During operation, the control system starts the air pump to inflate the air tank to the preset pressure. Then, according to the preset program, it sequentially opens the corresponding solenoid valves to different chambers, allowing high-pressure gas to enter the air chamber and achieve gradient pressure on the limb. After one cycle, the pressure is released uniformly. When pressure therapy is combined with heat therapy to improve local blood circulation and relieve muscle fatigue, existing equipment usually cannot directly integrate heating functions. Medical staff or patients often need to place a hot towel or external hot water bottle between the airbag and the skin. This method not only makes it difficult to maintain a stable heat temperature, but the additional heat source also affects the fit between the airbag and the limb, resulting in uneven pressure distribution and thus unstable treatment effects. Summary of the Invention

[0004] To improve the stability of treatment effects, this application provides an intermittent pneumatic pressure therapy device with an integrated heating module.

[0005] The intermittent pneumatic pressure therapy device with integrated heating module provided in this application adopts the following technical solution: An intermittent pneumatic pressure therapy device with an integrated heating module includes a main unit, an air bladder sleeve, and an air guide tube. The main unit is provided with a first connector for connecting to the air guide tube, and the air bladder sleeve is provided with a second connector for connecting to the air guide tube. The air bladder sleeve includes a wear-resistant outer layer, a flexible electric heating layer, a heat insulation layer, and a contact inner layer stacked sequentially from the outside to the inside. Metal heat-conducting wires are distributed within the flexible electric heating layer. An electrical plug shell is connected to the side of the wear-resistant outer layer opposite to the flexible electric heating layer. The ends of the metal heat-conducting wires converge at the electrical plug shell for connecting to an external adjustable temperature power supply device.

[0006] By adopting the above technical solution, the airbag sleeve integrates a flexible electric heating layer, which can be heated by an external power source to achieve simultaneous pressure therapy and heat therapy. This avoids the impact of additional heat therapy on the airbag's fit and improves the comfort and stability of the treatment effect.

[0007] Optionally, a protective shell is fixedly disposed on the wear-resistant outer layer, and the plug-in shell is rotatably installed inside the protective shell; an avoidance groove is provided on the side wall of the protective shell away from the wear-resistant outer layer, and the plug-in shell is disposed corresponding to the avoidance groove; a rotating component for driving the plug-in shell to rotate is provided inside the protective shell; and a blood oxygen detection unit for detecting blood oxygen is disposed on the wear-resistant outer layer.

[0008] By adopting the above technical solutions, the protective shell effectively protects the plug-in housing, preventing damage from external impacts and preventing leakage hazards caused by exposed metal heating wire connections. The rotating component can drive the plug-in housing to rotate within the protective shell, facilitating the adjustment of the plug-in housing's interface orientation according to the usage scenario, simplifying the plug-in and unplugging of external power supplies, and improving the ease of use of the device. The clearance groove provides space for the exposed interfaces of the plug-in housing and the plugging and unplugging of power supplies, ensuring smooth wiring operations. In addition, the blood oxygen detection unit is located on the wear-resistant outer layer to monitor the user's blood oxygen saturation in real time. It can continuously acquire blood oxygen data during device use, providing a basis for health status assessment, and can provide timely warnings when blood oxygen levels are abnormal, enhancing the device's safety monitoring function.

[0009] Optionally, a support plate is fixedly installed inside the protective shell on both sides of the clearance groove, and the plug-in shell is disposed between the two support plates; a rotating rod is fixedly installed on both sides of the plug-in shell, the rotating rod is perpendicular to the support plate, and the end of the rotating rod away from the plug-in shell passes through the support plate and is rotatably connected to the support plate.

[0010] By adopting the above technical solution, the two support plates provide stable support for the plug-in shell and the rotating rod. The rotation of the rotating rod and the support plates enables the flexible rotation of the plug-in shell. The structural design is simple and the transmission is smooth. The plug-in shell is set between the two support plates, which can effectively limit the radial displacement of the plug-in shell, prevent the plug-in shell from deviating during rotation, and ensure the accuracy of the plug-in shell rotation.

[0011] Optionally, the rotating assembly includes a first gear and a rack, the first gear being fixedly connected to one end of one of the rotating rods away from the plug-in housing; the rack being slidably mounted on the inner bottom wall of the protective housing along its length and meshing with the first gear; the protective housing is provided with a moving assembly for driving the rack to move along its length.

[0012] By adopting the above technical solution, the moving component drives the rack to slide along the length of the protective shell. The rack meshes with the first gear, driving the first gear and the rotating rod to rotate, thereby realizing the rotation adjustment of the plug-in shell. Through the meshing transmission of the gear and rack, the linear motion is converted into rotational motion. The transmission accuracy is high and the power transmission is stable. The rotation angle of the plug-in shell can be precisely controlled to meet different interface orientation requirements.

[0013] Optionally, the moving component includes a transmission rod and a rotating plate. The transmission rod is perpendicular to the length direction of the rack, passes through the side wall of the protective shell away from the wear-resistant outer layer, and is rotatably connected to the protective shell. A second gear is fixedly installed at the end of the transmission rod located inside the protective shell. The side wall of the rack is provided with toothed ridges along its own length direction, and the second gear meshes with the toothed ridges of the rack side wall. The rotating plate is connected to the end of the transmission rod located outside the protective shell.

[0014] By adopting the above technical solution, the operator can rotate the rotating plate to drive the transmission rod and the second gear to rotate. The second gear meshes with the rack and pinion to drive the rack to slide, thereby realizing the indirect drive of the plug-in shell. The operation method is simple and does not require direct contact with the internal components of the protective shell. The rotational cooperation between the transmission rod and the protective shell ensures the smoothness of the transmission. The rotating plate provides the operator with a convenient point of force application, reducing the difficulty of operation.

[0015] Optionally, an annular sleeve is fixedly provided on the side of the protective shell away from the wear-resistant outer layer, and the rotating plate is located inside the annular sleeve; a sliding groove is provided on the side of the transmission rod away from the second gear along its own length direction, and a sliding rod is slidably connected in the sliding groove, with one end of the sliding rod near the rotating plate fixedly connected to the rotating plate; a first locking groove and a second locking groove are provided on the inner sidewall of the annular sleeve in the vertical direction, the first locking groove and the second locking groove are arranged sequentially along the inner circumference of the annular sleeve and penetrate the upper surface of the annular sleeve; a locking rod is fixedly provided on the sidewall of the rotating plate, and the locking rod is inserted and adapted to the first locking groove or the second locking groove.

[0016] By adopting the above technical solution, the annular sleeve protects the rotating plate and provides a mating base for the insertion of the locking rod. When the plug-in housing rotates to the required angle, it pushes the rotating plate to slide the sliding rod along the slide groove, inserting the locking rod into the corresponding first or second locking groove. This locks the rotating plate and the transmission rod, preventing the rotating plate from rotating due to vibration during equipment use and ensuring the stability of the plug-in housing interface orientation. The sliding fit between the sliding rod and the slide groove enables the axial movement of the rotating plate, facilitating the insertion and removal of the locking rod. The two locking grooves can meet the two commonly used interface orientation requirements of the plug-in housing, adapting to different usage scenarios.

[0017] Optionally, an auxiliary plate is fixedly sleeved on one end of the transmission rod outside the protective shell. The auxiliary plate is located on the side of the rotating plate facing the protective shell. A first spring is fixedly arranged between the auxiliary plate and the rotating plate, and the first spring is sleeved on the outside of the transmission rod.

[0018] By adopting the above technical solution, the first spring always provides elastic force to the rotating plate towards the auxiliary plate, ensuring that the locking rod and the locking groove are always tightly engaged, preventing the locking rod from loosening and improving the stability of the locking structure; the auxiliary plate supports the first spring and limits the axial movement distance of the rotating plate, preventing the sliding rod from coming out of the groove and ensuring the integrity of the structure; when unlocking is required, pulling the rotating plate to stretch the first spring will allow the locking rod to exit the locking groove, making the operation convenient.

[0019] Optionally, the second connector is fixedly disposed inside the protective shell, and the protective shell has a plug-in interface corresponding to the second connector on one side wall away from the wear-resistant outer layer.

[0020] By adopting the above technical solution, the second connector is placed inside the protective shell, which protects the second connector from damage caused by external impact and prevents the air tube from becoming loose after connection. The insertion interface provides operating space for the connection between the air tube and the second connector, ensuring the smoothness of the air tube insertion and removal operation, and making the overall structure more compact.

[0021] Optionally, the protective shell has guide rails fixedly installed on both sides of the insertion interface, and a sealing plate for sealing the insertion interface is provided between the two guide rails. The two ends of the sealing plate extend into the guide rails on the corresponding sides and slide in cooperation with the guide rails. The protective shell is provided with a driving component for driving the sealing plate to move.

[0022] By adopting the above technical solution, when the equipment is not in use, the sealing plate seals the plug interface under the action of the drive component, which can effectively prevent external dust and impurities from entering the protective shell through the plug interface, and avoid the accumulation of impurities causing internal components to jam or be damaged. The guide rail guides the movement of the sealing plate, ensuring the smooth movement of the sealing plate and the sealing performance. When it is necessary to connect the air duct, the drive component drives the sealing plate to slide along the guide rail, and the plug interface can be opened for wiring operations. The structure is reasonably designed and easy to use.

[0023] Optionally, the drive assembly includes a movable plate and a second spring. The movable plate is perpendicular to the sealing plate and fixedly connected to the end of the sealing plate away from the plug-in housing. A telescopic rod is provided between the movable plate and a side wall of the protective housing. The telescopic rod is composed of multiple slidingly connected rod sections, and the length direction of the telescopic rod is parallel to the movement direction of the rack. The second spring is sleeved on the outside of the telescopic rod and fixedly disposed between the movable plate and the side wall of the protective housing.

[0024] By adopting the above technical solution, the second spring always provides elastic force to the moving plate towards the insertion interface, ensuring that the sealing plate always maintains a sealing state on the insertion interface and guarantees the sealing effect. When the air duct is connected, as the rack moves, the rack and the moving plate abut against each other, pushing the moving plate to move away from the second connector. The second spring is compressed, and the moving plate drives the sealing plate to move, realizing the automatic opening of the insertion interface without the need for manual operation of the sealing plate, thus improving the ease of use. The telescopic rod supports the second spring, preventing bending deformation during the compression or rebound of the second spring, ensuring the working stability of the drive component, and at the same time limiting the movement direction of the moving plate and the sealing plate, further improving the movement accuracy of the sealing plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The airbag sleeve integrates a flexible electric heating layer, enabling simultaneous pressure therapy and heat therapy without the need for an external heat therapy device. This ensures a close fit between the airbag sleeve and the limb, guaranteeing even pressure distribution. The external adjustable temperature power supply device can precisely control the heating temperature. Combined with the uniform heat conduction characteristics of the metal heat-conducting wire, it achieves stable maintenance of the heat therapy temperature, effectively improving the stability of the treatment effect. 2. The protective housing is equipped with a rotating component and a moving component, which can flexibly adjust the orientation of the plug-in housing interface to facilitate the plugging and unplugging of the external power supply; the locking rod and the locking groove are engaged with the elastic force of the first spring to achieve stable locking of the plug-in housing angle, preventing loosening during equipment use and improving the ease of use and structural stability of the equipment. 3. The protective shell integrates a second connector and a sealing plate structure. When not in use, the sealing plate can effectively block dust and impurities from entering, protecting internal components. When connecting the air duct, the sealing plate can open automatically without manual operation, improving ease of use. The heat insulation layer reduces heat loss from the flexible electric heating layer, improving heat utilization efficiency and preventing burns. Combined with the wear-resistant properties of the wear-resistant outer layer, it extends the service life of the equipment and improves safety during use. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0029] This application discloses an intermittent pneumatic pressure therapy device with an integrated heating module.

[0030] refer to Figure 1 An intermittent pneumatic pressure therapy device with an integrated heating module includes a main unit 1 and an air delivery tube 11. The main unit 1 is provided with a first connector 12 for connecting the air delivery tube 11.

[0031] refer to Figure 1 and Figure 2 An airbag sleeve 2 is installed at the end of the air tube 11 furthest from the main unit 1. The airbag sleeve 2 adopts a multi-layer composite structure, consisting of a wear-resistant outer layer 21, a flexible electric heating layer 22, a heat insulation layer 23, and a contact inner layer 24 stacked sequentially from the outside to the inside. The wear-resistant outer layer 21 is located on the outermost side and serves as protection and wear resistance; the flexible electric heating layer 22 contains metal heat-conducting wires that can generate heat evenly after being energized; the heat insulation layer 23 is used to prevent heat from diffusing outward and to concentrate heat for inward transfer; the contact inner layer 24 is in direct contact with the patient's skin and conducts heat to the limb.

[0032] refer to Figure 1 and Figure 2 A protective shell 5 is fixedly connected to the side of the wear-resistant outer layer 21 away from the flexible electric heating layer 22. The protective shell 5 has a rectangular shell structure, and a plug-in shell 4 is rotatably installed inside it. The plug-in shell 4 is a shell made of insulating material, and the ends of the metal heat-conducting wires converge into the plug-in shell 4 to form a power interface for plugging in the power cord of an external adjustable temperature power supply device. A clearance groove 51 is provided on the side wall of the protective shell 5 away from the wear-resistant outer layer 21, and the plug-in shell 4 is positioned corresponding to the clearance groove 51. A blood oxygen detection unit 211 for detecting blood oxygen in the covered segment is provided on the outer side of the wear-resistant outer layer 21.

[0033] When the power socket 4 is rotated to the unfolded state, its interface end extends from the clearance groove 51 for easy plugging and unplugging of the power cord; when the power socket 4 is rotated to the retracted state, it is completely housed within the protective shell 5 to prevent damage from external impacts. Simultaneously, the blood oxygen detection unit 211, located on the wear-resistant outer layer 21, is used to monitor the blood oxygen saturation of the covered skin and tissue in real time. It can dynamically assess local blood circulation and oxygen supply during device use and trigger an alarm when blood oxygen levels are abnormal, further improving the safety and monitoring effectiveness of hot compress therapy.

[0034] refer to Figure 2 , Figure 3 and Figure 4 Inside the protective shell 5, on both sides of the clearance groove 51, there are fixed support plates 52, and the plug-in shell 4 is disposed between the two support plates 52. On both sides of the plug-in shell 4, there are fixed rotating rods 53, which are perpendicular to the support plates 52, and the end of the rotating rod away from the plug-in shell 4 passes through the support plate 52 and is rotatably connected to the support plate 52.

[0035] With the cooperation of the rotating rod 53 and the support plate 52, the plug-in housing 4 can rotate smoothly around the axis of the rotating rod 53 within the protective housing 5.

[0036] refer to Figure 2 , Figure 3 and Figure 4The protective housing 5 contains a rotating assembly 6 for driving the plug-in housing 4 to rotate. The rotating assembly 6 includes a first gear 61 and a rack 62. The first gear 61 is fixedly connected to one end of a rotating rod 53 away from the plug-in housing 4 and rotates coaxially with the rotating rod 53. The rack 62 is slidably mounted on the inner bottom wall of the protective housing 5 along its length. Toothed ridges are provided on both adjacent sides of the rack 62, and the front toothed ridges of the rack 62 mesh with the first gear 61. The protective housing 5 is provided with a moving assembly 7 for driving the rack 62 to move along its length.

[0037] The moving assembly 7 includes a transmission rod 71 and a rotating plate 72. The transmission rod 71 is perpendicular to the length direction of the rack 62, passes through the side wall of the protective shell 5 away from the wear-resistant outer layer 21, and is rotatably connected to the protective shell 5. A second gear 54 is fixedly installed at the end of the transmission rod 71 located inside the protective shell 5, and the second gear 54 meshes with the toothed edge of the side wall of the rack 62. The rotating plate 72 is connected to the end of the transmission rod 71 located outside the protective shell 5.

[0038] When the operator rotates the rotating plate 72, the plate 72 drives the transmission rod 71 to rotate, and the second gear 54 on the transmission rod 71 rotates accordingly. Through meshing transmission, the gear rack 62 is driven to slide along the length of the protective shell 5. The sliding gear rack 62 drives the first gear 61, which meshes with it, to rotate. The first gear 61 drives the plug-in shell 4 to rotate around its axis through the rotating rod 53, thereby realizing the switching between the plug-in shell 4 in the retracted state and the unfolded state. The entire process is smooth and requires little effort to operate.

[0039] refer to Figure 2 , Figure 3 and Figure 4 An annular sleeve 55 is fixedly installed on the side of the protective shell 5 away from the wear-resistant outer layer 21, and the rotating plate 72 is located inside the annular sleeve 55. A sliding groove 711 is formed along the length of the transmission rod 71 on the side away from the second gear 54. A sliding rod 712 is slidably connected within the sliding groove 711, and the end of the sliding rod 712 near the rotating plate 72 is fixedly connected to the rotating plate 72. A first locking groove 551 and a second locking groove 552 are formed vertically on the inner sidewall of the annular sleeve 55. The first locking groove 551 and the second locking groove 552 are arranged sequentially along the inner circumference of the annular sleeve 55 and penetrate the upper surface of the annular sleeve 55. A locking rod 56 is fixedly installed on the sidewall of the rotating plate 72, and the locking rod 56 is inserted into or fitted into the first locking groove 551 or the second locking groove 552. An auxiliary plate 57 is fixedly sleeved on one end of the transmission rod 71 outside the protective shell 5. The auxiliary plate 57 is located on the side of the rotating plate 72 facing the protective shell 5. A first spring 58 is fixedly installed between the auxiliary plate 57 and the rotating plate 72. The first spring 58 is sleeved on the outside of the transmission rod 71.

[0040] When the rotating plate 72 rotates to the unfolded position of the plug-in housing 4, the locking rod 56 is aligned with the first locking groove 551. Under the elastic force of the first spring 58, the locking rod 56 inserts into the first locking groove 551, locking the rotating plate 72 and preventing the plug-in housing 4 from rotating accidentally due to vibration during use. When it is necessary to retract the plug-in housing 4, the operator overcomes the elastic force of the first spring 58 and pulls the rotating plate 72 away from the protective housing 5, causing the locking rod 56 to exit the first locking groove 551. Then, the rotating plate 72 is rotated until the locking rod 56 aligns with the second locking groove 552. The rotating plate 72 is then released, and the locking rod 56, under the action of the first spring 58, inserts into the second locking groove 552, locking the plug-in housing 4 in the retracted state. The first spring 58 always provides elastic force to the rotating plate 72 towards the protective housing 5, ensuring a tight and reliable engagement between the locking rod 56 and the locking groove.

[0041] refer to Figure 2 and Figure 5 The protective shell 5 has a second connector 3 fixedly installed inside for connecting to the end of the air duct 11. A corresponding insertion interface 59 is provided on the side wall of the protective shell 5 away from the wear-resistant outer layer 21. One end of the air duct 11 is connected to the main unit 1 via a first connector 12, and the other end is inserted into the second connector 3 via the insertion interface 59, thus achieving airflow communication. Guide rails 8 are fixedly installed on both opposite sides of the insertion interface 59 inside the protective shell 5. A sealing plate 81 for sealing the insertion interface 59 is provided between the two guide rails 8. Both ends of the sealing plate 81 extend into the corresponding guide rails 8 and slide along the length of the guide rails 8, allowing it to move along the length of the guide rails 8. A drive assembly 9 is provided inside the protective shell 5 to drive the sealing plate 81 to move.

[0042] The drive assembly 9 includes a movable plate 91 and a second spring 92. The movable plate 91 is perpendicular to the sealing plate 81 and fixedly connected to its end away from the plug-in housing 4. A telescopic rod 82 is provided between the movable plate 91 and one side wall of the protective housing 5. The telescopic rod 82 is composed of multiple slidingly connected rod sections, and its length direction is parallel to the movement direction of the rack 62. The second spring 92 is sleeved on the outside of the telescopic rod 82 and fixedly disposed between the movable plate 91 and the side wall of the protective housing 5.

[0043] When the air duct 11 is not connected, the second spring 92 is in a naturally extended or slightly compressed state, pushing the moving plate 91 to keep the sealing plate 81 in the position of sealing the insertion interface 59, effectively preventing dust and foreign objects from entering the protective shell 5 and protecting the second connector 3 from contamination. When the air duct 11 needs to be connected, as the rack 62 moves, the rack 62 first abuts against the moving plate 91 and pushes the moving plate 91 away from the second connector 3. The second spring 92 is compressed, and at the same time, it drives the sealing plate 81 to slide along the guide rail 8, exposing the insertion interface 59, so that the air duct 11 can be inserted into the second connector 3. After use, as the rack 62 and the moving plate 91 disengage, the second spring 92 returns to its original position, pushing the moving plate 91 to move the sealing plate 81 back, and the sealing plate 81 re-seals the insertion interface 59. The telescopic rod 82 ensures the smooth movement of the moving plate 91 and provides guidance for the second spring 92, preventing the spring from deflecting.

[0044] The implementation principle of an intermittent pneumatic pressure therapy device with an integrated heating module in this application embodiment is as follows: When using the device, first adjust the interface orientation of the plug-in housing 4 according to the usage scenario, pull the rotating plate 72 to disengage the locking rod 56 from the locking groove, rotate the rotating plate 72 to drive the transmission rod 71 and the second gear 54 to rotate, the second gear 54 drives the rack 62 to slide, the rack 62 meshes with the first gear 61 to drive the rotating rod 53 and the plug-in housing 4 to rotate, after adjusting to the required angle, release the rotating plate 72, the elastic force of the first spring 58 drives the rotating plate 72 to move towards the auxiliary plate 57, so that the locking rod 56 is inserted into the corresponding first locking groove 551 or second locking groove 552, completing the angle locking of the plug-in housing 4, and then insert the power plug into the plug-in housing 4 through the clearance groove 51, connect the external adjustable temperature power supply device and adjust it to the required temperature. Simultaneously, as the rack 62 moves, it pushes the moving plate 91 to move. The second spring 92, guided by the telescopic rod 82, is compressed. The moving plate 91 moves the sealing plate 81, opening the connector 59. The air tube 11 connects to the second connector 3, and the other end of the air tube 11 connects to the first connector 12 of the main unit 1. Then, the airbag sleeve 2 is wrapped around the outside of the patient's limb, and the main unit 1 is activated, enabling simultaneous pressure therapy and heat therapy. After use, the air tube 11 is disconnected. The elasticity of the second spring 92 pulls the moving plate 91, causing the sealing plate 81 to reset and seal the connector 59. The power plug is then unplugged for storage. The entire process is simple and quick, allowing for precise control of the heat therapy temperature and uniform pressure distribution, effectively improving the stability of the treatment effect.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
