Description

Technical Field

[0002] The main cause of cardiovascular and cerebrovascular diseases is the abnormal metabolism of smooth muscle cells in the blood vessel wall. The blood vessel tissue and other tissues of the human body complete the metabolic process in a certain period, but because new cell tissues cannot be formed normally, the blood vessel wall itself has "defects", which makes it easy to produce inflammation. The blood vessels are not contracted smoothly, just like a tattered old pipe, which may be blocked or ruptured at any time. Blood vessels are important channels for blood circulation, and they are also controlled by the nervous system. Therefore, abnormal nervous system can also lead to blood supply disorders.

DETAILED DESCRIPTION

[0024] Embodiment 1 like Figure 1As shown, a cardiovascular rehabilitation therapy device includes a restraint member 1, the restraint member 1 is provided with a fixing portion 4, the restraint member 1 is disconnected in the middle and connected by a connecting member 7, the inner wall of the connecting member 7 is embedded with a first airbag 5 and a second airbag 6, the first airbag 5 and the second airbag 6 are alternately arranged, the inner wall of the restraint member 1 is provided with a self-cleaning component 2 for cleaning the surface of the first airbag 5 and the second airbag 6, and the side end face of the restraint member 1 is provided with a pressure supply component 3 for controlling the alternating changes in the internal pressure of the first airbag 5 and the second airbag 6.

[0025] Furthermore, the first airbag 5 and the second airbag 6 are each provided with multiple groups, which are alternately arranged on the inner wall of the restraint 1, and the connecting member 7 includes but is not limited to various adjustable connection forms such as adhesion and snap connection. Specifically, the connection length of the restraint 1 can be controlled by setting Velcro or snaps, and the self-cleaning component 2, the pressure supply component 3 and the connecting member 7 can all be made of flexible silicone material or wrapped with skin-friendly materials such as silicone.

[0026] When in use, first disconnect the restraint 1, wrap the restraint 1 around the patient to the position where it needs to be fixed, adjust the fixing part 4 to the corresponding area to protect the affected part, then close the restraint 1 through the connecting part 7 and make the connecting part 7 shrink and initially fit the patient, after fitting, supply pressure to the first airbag 5 or the second airbag 6 through the pressure supply component 3 so that the first airbag 5 and the second airbag 6 expand to fix the restraint 1, thereby protecting the patient's affected part, and the first airbag 5 and the second airbag 6 are softer than the traditional mechanical fixation and have a larger fitting surface to reduce the pressure on the patient's skin, and at the same time, the pressure supply component 3 can realize the change of the fixed contact surface of the device with the patient without affecting the fixing effect by alternately supplying pressure to the first airbag 5 or the second airbag 6, thereby avoiding the problem of poor bleeding caused by long-term pressure on a single part, and the alternating expansion of the first airbag 5 and the second airbag 6 can also help the blood circulation around the patient's affected part to facilitate the patient's recovery.

[0027] Embodiment 2 Based on the first embodiment, Figure 1 - Figure 2 and Figure 4 As shown, the self-cleaning component 2 includes a driving bar 10 and a cleaning rod 11. The cleaning rod 11 is slidably fitted on the inner wall of the restraining member 1. The driving bar 10 is fixedly connected to both ends of the cleaning rod 11, and the driving bar 10 is slidably embedded in the inner wall of the cleaning rod 11.

[0028] Furthermore, the outer surface of the cleaning rod 11 is covered with a cleaning layer, which is a cotton layer.

[0029] During use, a cleaning rod 11 is provided on the inner wall of the restraint 1. When the first airbag 5 and the second airbag 6 are alternately inflated, the cleaning rod 11 is limited by the driving bar 10. Under the pressure of the airbag expansion, the cleaning rod 11 will be pushed to slide along the surface of the first airbag 5 or the second airbag 6, thereby cleaning the surface of the first airbag 5 or the second airbag 6, avoiding long-term contact with the patient's surface due to sweat stains and the like, which may affect the patient's recovery.

[0030] like Figure 1 - Figure 3 and Figure 5 - Figure 6 As shown, the outer end surface of the pressure supply component 3 is penetrated by a first connecting tube 8 and a second connecting tube 9 , and the pressure supply component 3 is connected to the first airbag 5 and the second airbag 6 through the first connecting tube 8 and the second connecting tube 9 respectively.

[0031] Furthermore, the pressure supply component 3 can be connected to an external pressure source such as compressed air or oxygen through the first connecting tube 8 and the second connecting tube 9 to alternately supply air to the first airbag 5 and the second airbag 6. A heating module can also be embedded in the interior of the pressure supply component 3 to heat the internal medium of the first airbag 5 and the second airbag 6 to achieve a certain hot compress effect.

[0032] like Figure 1 - Figure 3 and Figure 5 - Figure 8 As shown, the pressure supply component 3 includes a pressure supply component body 13, a first cavity 20, a sealing partition 21, a second cavity 22 and a driving mechanism. The pressure supply component body 13 is fixedly connected to the outer end surface of the restraint 1. The interior of the pressure supply component body 13 is divided into a first cavity 20 and a second cavity 22 by the sealing partition 21. The first cavity 20 is connected to the first airbag 5 through the first connecting tube 8, and the second cavity 22 is connected to the second airbag 6 through the second connecting tube 9. The driving device is embedded in the pressure supply component body 13, and the driving mechanism is used to drive the reciprocating movement of the sealing partition 21.

[0033] When in use, in the initial state, gas or liquid is injected through the injection port on the top of the pressure supply component body 13, so that the first airbag 5 and the second airbag 6 are expanded synchronously until the restraint 1 can be fixed on the patient's affected part, and then the sealing partition 21 is driven to move by the driving mechanism, so that the volume of the first cavity 20 and the second cavity 22 inside the pressure supply component body 13 changes, causing the first airbag 5 and the second airbag 6 to expand alternately. Specifically, when the sealing partition 21 moves toward the first connecting tube 8, the medium inside the first cavity 20 is injected into the first airbag 5 through the first connecting tube 8, and the first airbag 5 continues to expand under pressure, so that the pressure at the contact point between the first airbag 5 and the patient increases, while the second airbag 5 expands alternately. When the internal pressure of the cavity 22 decreases with the movement of the sealing partition 21, the second airbag 6 contracts accordingly to reduce the surface pressure on the patient. Although the pressing area is reduced compared to the initial state, the pressing pressure is increased, thereby having a corresponding fixing effect. On the contrary, when the sealing partition 21 moves toward the second connecting tube 9, the pressure of the first airbag 5 decreases and the pressure of the second airbag 6 increases, thereby achieving the alternating expansion of the first airbag 5 and the second airbag 6 to limit the restraint 1. During the alternating process, the position of the restraint 1 is stable and has a good fixing effect. The alternating pressing of the first airbag 5 and the second airbag 6 can effectively avoid blood congestion, promote blood circulation, and accelerate patient recovery.

[0034] like Figure 1 - Figure 3 and Figure 5 - Fig.10 As shown, the driving mechanism includes a driving block 17, a rotating disk 18 and a limiting disk 19. The rotating disk 18 is embedded in the interior of the pressure supply component body 13. The rotating disk 18 is in contact with the sealing partition 21. The limiting disk 19 is rotatably embedded in the rotating disk 18. The driving block 17 is symmetrically arranged on both sides of the sealing partition 21, and the driving block 17 is clamped with the limiting disk 19. The limiting disk 19 and the rotating disk 18 are eccentrically arranged.

[0035] When in use, by controlling the rotation of the rotating disk 18, the rotating disk 18 is connected to a driving block 17 that is in contact with the sealing baffle 21, thereby pushing the sealing baffle 21 to move inside the pressure supply component body 13, and since the driving blocks 17 are arranged on both sides of the sealing baffle 21, the driving blocks 17 are rotatably connected to the rotating disk 18 through the limit disk 19, so that the rotating disk 18 can drive the sealing baffle 21 to slide back and forth inside the pressure supply component body 13 through the driving blocks 17 while rotating, thereby realizing alternating control of the first airbag 5 and the second airbag 6, and the rotating disk 18 can be driven to rotate by a variety of driving sources, such as a DC motor, etc., so that the device does not need to be connected to wires and can move with the user, reducing the inconvenience to the patient's life during use.

[0036] like Figure 1 - Fig.10As shown, the outer end surface of the rotating disk 18 is provided with a partial tooth groove 24, and one side of the side end surface of the driving bar 10 is provided with a bar tooth 12 adapted to the partial tooth groove 24, and two groups of driving bars 10 are arranged in parallel on both sides of the partial tooth groove 24.

[0037] Furthermore, the pressure supply component body 13 is provided with a rotating cavity 25 adapted to the rotating disk 18. The rotating disk 18 is rotatably connected to the pressure supply component body 13 through a rotating bearing 23. The rotating bearing 23 is embedded in the rotating cavity 25. The rotating bearing 23 is sealed through the rotating cavity 25, and the driving bar 10 passes through the restraining member 1 and extends to the interior of the rotating cavity 25.

[0038] During use, in order to improve the cleaning effect of the self-cleaning component 2, a local tooth groove 24 is set. When the rotating disk 18 rotates, the local tooth groove 24 drives the movement of the driving bar 10. When the rotating disk 18 rotates one circle, the driving bar 10 reciprocates once. By setting the initial position of the driving bar 10, when the rotating disk 18 drives the first airbag 5 or the second airbag 6 to contract, the rotating disk 18 synchronously drives the cleaning rod 11 to move along the surface of the first airbag 5 or the second airbag 6 in the contracted state, thereby cleaning the surface of the first airbag 5 or the second airbag 6, and at the same time avoiding the discomfort caused to the patient when the cleaning rod 11 moves.

[0039] like Figure 1 - Fig.12 As shown, a sliding cavity 28 is provided inside the driving block 17, a clamping rod 30 is elastically connected inside the sliding cavity 28, a clamping portion 31 is provided at the bottom of the clamping rod 30, and a limiting clamping groove 27 that is plugged into the clamping portion 31 is formed on the upper end surface of the limiting plate 19.

[0040] When in use, the driving block 17 is connected with the limiting slot 27 through the clamping portion 31 so that the limiting disk 19 can drive the sealing partition 21 to move back and forth through the driving block 17, and the clamping portion 31 can be set to a cone, a cross or a straight shape as needed.

[0041] like Figure 1 - Fig.12 As shown, a strong magnetic sheet 29 is provided at one end of the clamping rod 30 away from the clamping portion 31 , and a moving area 15 is provided on the outer end surface of the pressure supply assembly body 13 , and a magnetic sheet 14 is provided in close contact with the moving area 15 .

[0042] like Figure 1 - Fig.12 As shown, there are multiple groups of limit plates 19 , and the multiple groups of limit plates 19 rotate synchronously. The multiple groups of limit plates 19 are connected to each other through transmission members 26 .

[0043] Furthermore, the transmission member 26 includes but is not limited to various forms such as belts and chains, and a side panel of the pressure supply component body 13 can be set as a transparent cover 16 to facilitate observation of the status of the pressure supply component 3.

[0044] During use, in order to make the pressure of the first airbag 5 and the second airbag 6 adapt to different patients, it is necessary to control the movement of the sealing partition 21. In order to ensure the stability and reliability of the device, a magnetic sheet 14 is provided. In the initial state of the device, the sealing partition 21 is located in the middle of the pressure supply component body 13. At this time, the sealing partition 21 corresponds to the position of the moving area 15. By placing the magnetic sheet 14 in close contact, the magnetic sheet 14 causes the clamping rod 30 to move up and disengage from the limit slot 27 under the action of magnetic force, so that the driving block 17 can move along the moving area 15 under the action of the magnetic sheet 14. The magnetic sheet 14 drives the driving block 17 to select the limit plate 19 in the appropriate position, thereby controlling the movement of the sealing partition 21, thereby controlling the fitting pressure of the first airbag 5 and the second airbag 6. After use, the magnetic sheet 14 is convenient for medical staff to store and centrally manage.

[0045] Working principle: first, disconnect the restraint 1, wrap the restraint 1 around the position where the patient needs to be fixed, adjust the fixing part 4 to the corresponding area to protect the affected part, then close the restraint 1 through the connecting part 7 and make the connecting part 7 shrink and initially fit the patient, after fitting, supply pressure to the first airbag 5 or the second airbag 6 through the pressure supply component 3 so that the first airbag 5 and the second airbag 6 expand to fix the restraint 1, thereby protecting the patient's affected part, and the first airbag 5 and the second airbag 6 are softer than traditional mechanical fixation and have a larger fitting surface to reduce pressure on the patient's skin, and at the same time, the pressure supply component 3 can alternately supply pressure to the first airbag 5 or the second airbag 6 so that the device can be fixed to the patient without affecting the fixation effect. The change of the contact surface can avoid the problem of poor bleeding caused by long-term pressure on a single part, and the alternating expansion of the first airbag 5 and the second airbag 6 can also help the blood circulation around the patient's affected part to facilitate the patient's recovery. A cleaning rod 11 is provided on the inner wall of the restraint 1. When the first airbag 5 and the second airbag 6 are alternately expanded, the cleaning rod 11 is limited by the driving bar 10. Under the pressure of the airbag expansion, the cleaning rod 11 will be pushed to slide along the surface of the first airbag 5 or the second airbag 6, so as to clean the surface of the first airbag 5 or the second airbag 6, so as to avoid the first airbag 5 and the second airbag 6 from being in contact with the patient for a long time and adhering to sweat stains and the like, which will affect the patient's recovery. In the initial state, gas or liquid is injected through the injection port on the top of the pressure supply component body 13, so that the first airbag 5 and the second airbag 6 are cleaned. The first airbag 5 and the second airbag 6 are expanded synchronously until the restraint 1 can be fixed on the patient's affected part, and then the sealing baffle 21 is driven to move by the driving mechanism, so that the volume of the first cavity 20 and the second cavity 22 inside the pressure supply component body 13 changes, causing the first airbag 5 and the second airbag 6 to expand alternately. Specifically, when the sealing baffle 21 moves toward the first connecting tube 8, the internal medium of the first cavity 20 is injected into the interior of the first airbag 5 through the first connecting tube 8, and the first airbag 5 continues to expand under pressure, so that the pressure at the contact point between the first airbag 5 and the patient increases, while the internal pressure of the second cavity 22 decreases due to the movement of the sealing baffle 21, and the second airbag 6 contracts accordingly, reducing the surface pressure on the patient. Although the pressing area is reduced compared to the initial state, The pressing pressure increases, thereby having a corresponding fixing effect. Conversely, when the sealing partition 21 moves toward the second connecting pipe 9, the pressure of the first airbag 5 decreases and the pressure of the second airbag 6 increases, thereby realizing the alternating expansion of the first airbag 5 and the second airbag 6 to limit the restraint 1. In the alternating process, the position of the restraint 1 is stable and has a good fixing effect. At the same time, the alternating pressing of the first airbag 5 and the second airbag 6 can effectively avoid blood congestion, promote blood circulation, and accelerate patient recovery. By controlling the rotation of the rotating disk 18, the rotating disk 18 is connected to a driving block 17 that is in contact with the sealing partition 21, thereby pushing the sealing partition 21 to move inside the pressure supply component body 13, and because the driving block 17 is arranged on both sides of the sealing partition 21,The driving block 17 is rotatably connected to the rotating disk 18 through the limit plate 19, so that the rotating disk 18 can drive the sealing partition 21 to slide back and forth inside the pressure supply component body 13 through the driving block 17 while rotating, thereby realizing the alternating control of the first airbag 5 and the second airbag 6, and the rotating disk 18 can be driven to rotate by a variety of driving sources, such as a DC motor, so that the device can be moved with the user without connecting wires, reducing the inconvenience to the patient's life during use. In order to improve the cleaning effect of the self-cleaning component 2, a local tooth groove 24 is set, and the movement of the driving bar 10 is driven by the local tooth groove 24 when the rotating disk 18 rotates. When the rotating disk 18 rotates one circle, the driving bar 10 reciprocates once. By setting the initial position of the driving bar 10, when the rotating disk 18 drives the first airbag 5 or the second airbag 6 to contract, the rotating disk 18 synchronously drives the cleaning rod 11 to move along the surface of the first airbag 5 or the second airbag 6 in the contracted state, thereby cleaning the surface of the first airbag 5 or the second airbag 6, and at the same time, it can avoid the discomfort caused to the patient when the cleaning rod 11 moves. The driving block 17 is connected with the limiting card slot 27 through the clamping portion 31 so that the limiting disk 19 can drive the sealing partition 21 to move back and forth through the driving block 17, and the clamping portion 31 can be set to a cone, a cross or a straight shape as needed. In order to make the pressure of the first airbag 5 and the second airbag 6 adapt to different patients, it is necessary to control the movement of the sealing partition 21. In order to ensure the stability and reliability of the device, a magnetic suction sheet 14 is provided. In the initial state of the device, the sealing partition 21 is located in the middle of the pressure supply component body 13. At this time, the sealing partition 21 and The position of the mobile area 15 corresponds to that of the magnetic sheet 14, which is placed in close contact. Under the action of magnetic force, the magnetic sheet 14 causes the clamping rod 30 to move up and disengage from the plug-in of the limit slot 27, so that the driving block 17 can move along the mobile area 15 under the action of the magnetic sheet 14, and the magnetic sheet 14 drives the driving block 17 to select the limit plate 19 at a suitable position, thereby controlling the movement of the sealing partition 21, thereby controlling the fitting pressure of the first airbag 5 and the second airbag 6, and the magnetic sheet 14 is convenient for medical staff to store and centrally manage after use.
