Description

Technical Field

[0001] This invention belongs to the field of medical device technology and relates to a rehabilitation training device and control method for peritoneal dialysis patients. Background Technology

[0002] Peritoneal dialysis (PD) is one of the main renal replacement therapies for end-stage renal disease (ESRD). It is inexpensive, simple to perform, and patients and their families can perform dialysis at home. Home peritoneal dialysis breaks away from the traditional medical model where patients rely on hospitals and medical staff for treatment, offering greater flexibility and autonomy, and improving patients' quality of life.

[0003] Current nephrology guidelines and expert consensus broadly support exercise rehabilitation training for maintenance peritoneal dialysis patients to promote their overall health and quality of life. However, these guidelines and evidence summaries typically recommend that patients empty their dialysis fluid before engaging in exercises that may increase intra-abdominal pressure to reduce potential health risks. While this recommendation is based on patient safety concerns, it is somewhat general and conservative, failing to adequately consider the specific effects of different exercises on intra-abdominal pressure and their practical significance for patient safety. In reality, many exercises, while causing a slight increase in intra-abdominal pressure, are usually insufficient to pose a safety risk to patients with remaining dialysis fluid. Therefore, categorizing all exercises that may increase intra-abdominal pressure as unsuitable for peritoneal dialysis patients may unnecessarily limit their opportunities for exercise, thereby impacting their rehabilitation outcomes and quality of life.

[0004] In addition, a significant proportion of peritoneal dialysis patients suffer from frailty, typically manifested as decreased walking speed, fatigue, and muscle weakness, leading to a decline in physical function. This not only affects patients' daily functions and self-care abilities but may also result in a reduction in quality of life and survival rate. The recognized intervention method for frailty is multi-component exercise, which increases the necessity and urgency of providing appropriate exercise intervention for maintenance peritoneal dialysis patients.

[0005] Currently, rehabilitation training for peritoneal dialysis patients usually relies on their own feelings to determine whether training is appropriate, without systematic and standardized guidance devices or equipment to help patients with rehabilitation training. This leads to certain safety risks for patients training on their own, and the training effect is not ideal. Summary of the Invention

[0006] The purpose of this invention is to provide a rehabilitation training device and control method for peritoneal dialysis patients, to provide standardized guidance for the rehabilitation training of peritoneal dialysis patients, and to ensure the safety and effectiveness of the training.

[0007] To achieve the above objectives, the basic solution of the present invention is: a rehabilitation training device for peritoneal dialysis patients, comprising an abdominal pressure acquisition module, a control mechanism, and a training mechanism;

[0008] The abdominal pressure acquisition module is used to acquire the patient's abdominal pressure information. The control mechanism includes multiple comparators. The first input terminal of the comparator is connected to the output terminal of the abdominal pressure acquisition module, and the second input terminal of the comparator is connected to a memory with built-in different pressure thresholds. The output terminals of the multiple comparators correspond to different training levels of the training mechanism.

[0009] The training mechanism includes a display screen, a support plate, and multiple placement boxes. The display screen is mounted on the support plate, and the output of the comparator is connected to the input of the display screen. The display screen is used to display the training level and the corresponding pre-stored training scheme.

[0010] The support plate is vertically arranged, and a vertical groove and several horizontal grooves are provided on one side of the support plate. The vertical groove runs through the center line of all the horizontal grooves.

[0011] The multiple placement boxes contain training tools corresponding to different training levels, and the external connection of the placement boxes is a movable component that can move along the vertical or horizontal groove.

[0012] The working principle and beneficial effects of this basic solution are as follows: This technical solution uses an abdominal pressure acquisition module to collect the patient's abdominal pressure information and transmits it to the comparator in the control mechanism. Each comparator compares the collected abdominal pressure information with the pressure threshold in the corresponding memory to determine the appropriate training level for the patient's abdominal pressure.

[0013] The training facility displays the training level and corresponding training plan determined by the control mechanism on a screen for easy viewing by the patient, thus guiding their rehabilitation training. Various training tools are placed in their corresponding storage boxes, which can be slid to different positions via vertical and horizontal slots on the support plate for easy access. The boxes can also be positioned to accommodate unused needs; for example, the walking belt can be moved to the bottom of the support plate when in use and to the top when not in use, avoiding taking up space below and facilitating placement. Each storage box also provides a seat for the patient to rest at any time. The boxes at different heights also provide gripping support during bending, squatting, and other movements.

[0014] Furthermore, the training tool includes adjustable resistance handles, pedals, ropes, and walking treads, suitable for various strength training exercises.

[0015] The training tools are versatile and easy to use.

[0016] Furthermore, it also includes a lifting mechanism, which comprises a lifting plate and a lifting machine;

[0017] The lifting plate slides along the vertical groove, the lifting machine is installed on the top of the support plate, the lifting end of the lifting machine is connected to the lifting plate, and the moving part can be moved to the upper surface of the lifting plate.

[0018] A lifting mechanism is installed to move the placement box that needs to be moved to the upper surface of the lifting plate in the vertical slot via a moving component. The lifting machine then moves the lifting plate up and down, thereby moving the placement box on the lifting plate up and down to change its position and reduce manpower consumption.

[0019] Furthermore, it also includes a drop protection mechanism, which includes an elastic strap, an elastic connecting strap, a pivot, a tension sensor, and a tension comparator;

[0020] One end of the elastic strap is provided with a locking block, and the other end is provided with several locking slots at different positions. The locking block can be connected to the locking slots at different positions to control the tightening or loosening of the elastic strap.

[0021] One end of the elastic connecting strip is connected to the elastic binding strip, and the other end is connected to the rotating shaft. The rotating shaft is rotatably mounted on the support plate and is connected to a power source that controls its rotation.

[0022] The tension sensor is mounted on the elastic connecting belt to collect the tension information of the elastic connecting belt. The output end of the tension sensor is connected to the first input end of the tension comparator. The second input end of the tension comparator is connected to a tension threshold memory. The output end of the tension comparator is connected to the control end of the power source.

[0023] The elastic band can be wrapped around the patient's body parts through the locking and slot structure of the elastic band. The elastic band is then connected to the support plate through the elastic connecting band via the pivot. In case the patient may move accidentally and fall, the elastic connecting band can be collected by rotating the pivot, thereby providing support to the patient and preventing a fall.

[0024] A tension sensor collects the tension information of the elastic connecting band and transmits it to a tension comparator. The comparator compares the collected tension signal with a tension threshold signal. When a patient is likely to fall, the tension on the elastic connecting band increases. At this time, the collected tension signal value is greater than or equal to the tension threshold. The tension comparator outputs a control signal to the control terminal of the power source, controlling the rotation of the shaft, causing the elastic connecting band to gradually wind around the shaft and tighten.

[0025] Furthermore, the anti-fall mechanism also includes an airbag, a first placement box, a second placement box, and a mixing container;

[0026] The airbag is installed on the outside of the elastic strap, and the first placement box, the second placement box, and the mixing container are all installed on the support plate;

[0027] The first placement box contains a mixed solution of sodium bicarbonate and foaming agent, and the second placement box contains an aqueous solution of aluminum sulfate. The mixing container is located below the first and second placement boxes. The bottoms of the first and second placement boxes are connected to the mixing container, and each connection point is equipped with a normally closed electric valve that allows one-way flow into the mixing container.

[0028] The output of the tension comparator is connected to the control terminal of the normally closed electric valve, and the mixing container is connected to the air bag through an air tube.

[0029] When a patient is at risk of falling, the tension on the elastic connecting band increases. If the collected tension signal value is greater than or equal to the tension threshold, the tension comparator outputs a control signal to the control terminal of the normally closed electric valve. The normally closed electric valve opens, and the first and second placement boxes simultaneously connect to the mixing container. The two solutions mix, generating a large amount of carbon dioxide gas. This gas enters the airbag through the trachea, causing the airbag to inflate and provide cushioning against the fall. This process is rapid, with fast gas generation and rapid airbag inflation, ensuring timely fall prevention.

[0030] Furthermore, a timer is provided at the normally closed electric valve to control the normally closed electric valve to automatically close after a preset time.

[0031] By using a timer, the normally closed electric valve can be automatically closed after being opened for a certain period of time, so that the solution in the first and second placement boxes will not be completely discharged at once, ensuring that they can be used multiple times.

[0032] Furthermore, the top of the placement box is provided with an opening, and a door panel is hinged to the opening.

[0033] The box has an opening and a door for easy access to items.

[0034] The present invention also provides a control method for a rehabilitation training device for peritoneal dialysis patients, comprising the following steps:

[0035] S1, the abdominal pressure acquisition module acquires the abdominal pressure and determines the level of abdominal pressure;

[0036] S2, When the abdominal pressure is below the first threshold and is in the first level, the handle, foot pedal, and pull rope inside the box can be removed, and any of the handle, foot pedal, or pull rope exercise methods can be used for exercise;

[0037] When the abdominal pressure is higher than the first threshold and lower than the second threshold, and is in the second level, place the handle inside the box and the foot pedal can be removed. You can exercise using either the handle or the foot pedal.

[0038] When the abdominal pressure is higher than the second threshold and lower than the third threshold, and is in the third level, the handle inside the box can be removed and exercised using the handle.

[0039] When abdominal pressure exceeds the third threshold and is at level four, all exercise equipment placed in the box should not be removed, and exercise should be stopped.

[0040] Different exercises are performed depending on the abdominal pressure, ensuring the safety of the body while exercising.

[0041] Furthermore, it also features a force regulation step:

[0042] When the abdominal pressure is below the first threshold and is in the first level, the force of the handle, foot pedal, and rope is in the high force range and changes rapidly at the first speed within the high force range.

[0043] When the abdominal pressure is higher than the first threshold and lower than the second threshold, it is in the second level. The force of the handle and foot pedal is in the medium force range and changes slowly at the second speed within the medium force range.

[0044] When the abdominal pressure is above the second threshold but below the third threshold, it is in the third level, and the handle force is stably at a low force value level.

[0045] The force changes according to abdominal pressure, which improves the effectiveness and fun of the workout. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0050] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0051] This invention discloses a rehabilitation training device for peritoneal dialysis patients. By accurately monitoring intra-abdominal pressure and adjusting the training plan based on the data, it can provide a safe and effective exercise rehabilitation training program for maintenance peritoneal dialysis patients. Figure 1 As shown, the rehabilitation training device includes an abdominal pressure acquisition module, a control mechanism, and a training mechanism.

[0052] The abdominal pressure acquisition module is used to collect the patient's abdominal pressure information. The abdominal pressure acquisition module can use the pressure sensor and displacement sensor in the existing patent CN200410009166.6 to perform non-invasive detection of intra-abdominal pressure, or use strain gauges, respiratory inductively coupled plasma plethysmography, or abdominal tension meters, as well as ultrasound-based IAP monitoring technologies (such as tonometer, abdominal wall thickness, Doppler or laser), bioelectrical impedance analysis, microwave reflectometer, and digital image correlation technology for detection.

[0053] The control mechanism includes multiple comparators. The first input of the comparators is electrically connected to the output of the abdominal pressure acquisition module, and the second input of the comparators is electrically connected to a memory with different pressure thresholds. The outputs of the multiple comparators correspond to different training levels of the training mechanism.

[0054] The training mechanism includes a display screen 2, a support plate 1, and multiple placement boxes 3. The display screen 2 is mounted on the support plate 1 (e.g., riveted, glued, etc.). The output terminal of the comparator is electrically connected to the input terminal of the display screen 2. The display screen 2 is used to display the training level and the corresponding pre-stored training scheme.

[0055] The support plate 1 is vertically arranged, and its bottom is fixedly connected to the ground (e.g., by welding, riveting, screw connection, etc.). One side of the support plate 1 is provided with a vertical groove 4 and several horizontal grooves 5, wherein the vertical groove 4 runs through the center line of all the horizontal grooves 5.

[0056] Multiple placement boxes 3 contain training tools corresponding to different training levels. The external connection of each placement box 3 includes a movable component 6 that can move along a vertical groove 4 or a horizontal groove 5. The movable component 6 can be a slider (with an anti-slip layer on its surface) or a moving trolley that can automatically move within the horizontal groove 5. Preferably, the top of the placement box 3 has an opening, and a door panel is hinged to the opening. The opening and door panel on the placement box 3 facilitate the loading and unloading of items. The training tools include adjustable resistance handles, foot pedals, ropes, and walking tracks, suitable for various strength training exercises.

[0057] During use, the abdominal pressure acquisition module collects the patient's abdominal pressure information and transmits it to the comparator in the control mechanism. Each comparator compares the collected abdominal pressure information with the pressure threshold in the corresponding memory to determine the appropriate training level for the patient's abdominal pressure.

[0058] The training facility displays the training level and corresponding training plan determined by the control mechanism on the display screen 2, allowing patients to easily view and guide their rehabilitation training. Various training tools are placed in their corresponding storage boxes 3, which can slide to different positions via the vertical grooves 4 and horizontal grooves 5 on the support plate 1 for easy access. They can also be positioned to accommodate unused needs; for example, the walking belt can be moved to the bottom of the support plate 1 when in use and to the top when not in use, avoiding taking up space below and facilitating placement. Each storage box 3 provides a seat for patients to rest at any time. The storage boxes 3 at different heights can also be gripped by patients, providing support during bending, squatting, and other movements.

[0059] In a preferred embodiment of the present invention, the rehabilitation training device for peritoneal dialysis patients further includes a lifting mechanism 7, which comprises a lifting plate 8 and a lifting mechanism 7. The lifting mechanism 7 can be a cylinder, hydraulic cylinder, lead screw and nut, conveyor belt, or other mechanism. The lifting plate 8 slides along the vertical groove 4 and is horizontally arranged. The lifting mechanism 7 is installed on the top of the support plate 1, and the lifting end of the lifting mechanism 7 is fixedly connected to the edge of the lifting plate 8 (e.g., by welding, bonding, etc.). The moving part 6 can move to the upper surface of the lifting plate 8.

[0060] A lifting mechanism 7 is installed. The placement box 3, which needs to be moved, is moved to the upper surface of the lifting plate 8 at the vertical slot 4 via the moving part 6. The lifting mechanism 7 drives the lifting plate 8 to move up and down, thereby moving the placement box 3 on the lifting plate 8 up and down, realizing the change of position and height, and reducing manpower consumption. A control button can be installed on the support plate 1. The output end of the control button is electrically connected to the control end of the lifting mechanism 7 to control the operation of the lifting mechanism 7.

[0061] In a preferred embodiment of the present invention, the rehabilitation training device for peritoneal dialysis patients further includes a fall protection mechanism, which comprises an elastic band, an elastic connecting band, a rotating shaft, a tension sensor, and a tension comparator. One end of the elastic band is fixedly provided with a locking block (e.g., welded, bonded), and the other end is provided with several slots at different positions. The locking block can connect to the slots at different positions to control the tightening or loosening of the elastic band.

[0062] One end of the elastic connecting strip is connected to the elastic strap (e.g., through binding, bonding, riveting, etc.), and the other end is fixedly connected to the rotating shaft (e.g., through bonding, welding, etc.). One or more elastic connecting strips can be provided to ensure stable connection to the elastic strap. The rotating shaft is rotatably mounted on the support plate 1 and is connected to a power source that controls its rotation. The power source can be a motor, which is welded to the support plate 1. The output shaft of the motor is coaxially and fixedly connected to one end of the rotating shaft (e.g., through pin connection, welding, etc.).

[0063] A tension sensor is mounted on the elastic connecting belt to collect the tension information acting on it. The output of the tension sensor is electrically connected to the first input of a tension comparator, the second input of which is electrically connected to a tension threshold memory, and the output of the comparator is electrically connected to the control terminal of the power source.

[0064] The elastic band can be tied to the patient's body parts through the locking block and slot structure. Then, the elastic band is connected to the support plate 1 through the elastic connecting band via the rotating shaft. When the patient may move accidentally and fall, the elastic connecting band can be collected by rotating the shaft, thereby providing support for the patient and preventing a fall.

[0065] A tension sensor collects the tension information of the elastic connecting band and transmits it to a tension comparator. The comparator compares the collected tension signal with a tension threshold signal. When a patient is likely to fall, the tension on the elastic connecting band increases. At this time, the collected tension signal value is greater than or equal to the tension threshold. The tension comparator outputs a control signal to the control terminal of the power source, controlling the rotation of the shaft, causing the elastic connecting band to gradually wind around the shaft and tighten.

[0066] In a preferred embodiment of the present invention, the anti-fall mechanism further includes an airbag, a first placement box, a second placement box, and a mixing container. The airbag is installed on the outside of the elastic strap, and the first placement box, the second placement box, and the mixing container are all fixedly installed (e.g., welded, glued, etc.) on the support plate 1. Both the first and second placement boxes have valves, which facilitate the removal and placement of the solution by opening the valves.

[0067] The first placement box contains a mixed solution of sodium bicarbonate and foaming agent, and the second placement box contains an aqueous solution of aluminum sulfate. A mixing container is located below both placement boxes, and the bottoms of both boxes are connected to the mixing container. Each connection point is equipped with a normally closed electric valve that allows one-way flow into the mixing container. The output of the tension comparator is electrically connected to the control terminal of the normally closed electric valve. The mixing container is connected to the air bladder via an air tube.

[0068] When a patient is at risk of falling, the tension on the elastic connecting band increases. If the collected tension signal value is greater than or equal to the tension threshold, the tension comparator outputs a control signal to the control terminal of the normally closed electric valve. The normally closed electric valve opens, and the first and second placement boxes simultaneously connect to the mixing container. Under gravity, the solutions in the first and second placement boxes fall into the mixing container, where they mix and produce a large amount of carbon dioxide gas. This gas enters the airbag through the trachea, causing the airbag to inflate and provide cushioning against the fall. This process is rapid, with fast gas generation and rapid airbag inflation, ensuring timely fall prevention.

[0069] Preferably, a timer is installed at the normally closed electric valve to control its automatic closure after a preset opening time. By controlling the normally closed electric valve to automatically close after a certain period of time, the solution in the first and second placement boxes is not completely drained at once, ensuring multiple uses.

[0070] The present invention also provides a control method for a rehabilitation training device for peritoneal dialysis patients, comprising the following steps:

[0071] S1, the abdominal pressure acquisition module acquires the abdominal pressure and determines the level of abdominal pressure;

[0072] S2, when the abdominal pressure is below the first threshold and is in the first level, the handle, foot pedal and pull rope in the box 3 can be taken out, and any of the handle, foot pedal and pull rope exercise methods can be used for exercise.

[0073] When the abdominal pressure is higher than the first threshold and lower than the second threshold, and is in the second level, the handle and foot pedal inside the box 3 can be removed, and either the handle or foot pedal exercise method can be used for exercise.

[0074] When the abdominal pressure is higher than the second threshold and lower than the third threshold, and is in the third level, the handle in the placement box 3 can be removed and exercised using the handle;

[0075] When the abdominal pressure exceeds the third threshold and is at level four, the exercise equipment in box 3 should not be removed, and exercise should be stopped.

[0076] Different exercises are performed depending on the abdominal pressure, ensuring the safety of the body while exercising.

[0077] In a preferred embodiment of the present invention, a force adjustment step is further included:

[0078] When the abdominal pressure is below the first threshold and is in the first level, the force of the handle, foot pedal, and rope is in the high force range and changes rapidly at the first speed within the high force range.

[0079] When the abdominal pressure is higher than the first threshold and lower than the second threshold, it is in the second level. The force of the handle and foot pedal is in the medium force range and changes slowly at the second speed within the medium force range.

[0080] When the abdominal pressure is above the second threshold but below the third threshold, it is in the third level, and the handle force is stably at a low force value level.

[0081] The force changes according to abdominal pressure, which improves the effectiveness and fun of the workout.
