Abstract
Description
Technical Field
[0001] This invention specifically relates to a post-cardiovascular interventional procedure relief device. Background Technology
[0002] Cardiovascular interventional surgery is an important means of treating cardiovascular diseases such as coronary heart disease and arrhythmia. It has the advantages of minimal trauma and rapid recovery. However, patients are prone to discomfort such as swelling, pain and muscle tension at the puncture site and surrounding tissues after the operation. They need to use a relaxation device to assist in recovery. Most of the existing relaxation devices after cardiovascular interventional surgery use a single relaxation method.
[0003] Some devices promote blood circulation by inflating and pressing an airbag, but prolonged pressure can easily cause local numbness in patients and cannot relieve muscle stiffness. Other devices use a rolling massage structure, which can relax muscles, but for patients with low tolerance in the early postoperative period, the massage intensity is difficult to match and may cause secondary stimulation.
[0004] For example, Chinese patent CN210785012U provides a post-cardiovascular interventional nursing relief device. Airbags are fixedly connected to the inner walls of the left and right sides of the shell. Tubes are fixedly connected to the bottom front of the two airbags. The outer ends of the tubes pass through the shell and are fixedly connected to a hand-squeezable ball. Patients or caregivers can press the hand-squeezable ball to make the airbags repeatedly expand and contract, thereby pressing the patient's affected limb. The pressing time, frequency and force can be freely adjusted.
[0005] However, existing devices lack a function switching mechanism, and patients' tolerance varies at different recovery stages after surgery. For example, gentle pressure is needed in the early postoperative period, while moderate massage is required in the middle recovery period. Single-function devices cannot meet dynamic needs, thus limiting their practicality. In view of this, a postoperative relief device for cardiovascular intervention is proposed to solve the above problems. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this invention proposes a post-cardiovascular interventional therapy device to solve the technical problem mentioned in the background art, which is that most existing therapy devices only have a single therapy function and are not convenient to switch between pressure therapy and rolling massage therapy according to the patient's tolerance, thus reducing their practicality.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a post-cardiovascular interventional therapy relief device, comprising: The housing has a drive motor installed on it. An airbag is fixedly installed inside the housing via a mounting plate. The airbag has multiple sets of gaps. The housing also has a slidable lever. An air pumping mechanism is provided on the housing to circulate and pump air from the airbag; A first movable plate is slidably disposed within the housing in a direction toward the inner side of the housing, and a massage mechanism is provided on the first movable plate; and A switching drive mechanism, disposed on the housing, converts the sliding of the toggle block into driving the drive motor, which can be selectively connected to the air pumping mechanism and the massage mechanism.
[0008] In a preferred embodiment, the pumping mechanism includes: A piston cylinder is fixedly mounted on the housing and communicates with the air bladder; a piston rod is slidably mounted inside the piston cylinder. A mounting wheel is rotatably mounted on the housing and connected to the switching drive mechanism, which drives the mounting wheel to rotate; and The drive rod has one end eccentrically hinged to the mounting wheel and the other end hinged to the piston rod.
[0009] In a preferred embodiment, the housing is provided with a guide seat, the piston rod slides through the guide seat, and an elastic element is provided between the end of the piston rod and the guide seat.
[0010] In a preferred embodiment, the lever is fixedly connected to the first movable plate by a connecting rod, which is slidably inserted through the housing.
[0011] In a preferred embodiment, the massage mechanism includes: The second movable plate is slidably disposed on one side of the first movable plate along the axis of the housing; Multiple sets of massage rollers are provided, all of which are located inside the second movable plate. The massage rollers can extend into the gaps created in the airbag. A drive assembly is disposed on the housing and connected to the second movable plate to drive the second movable plate to reciprocate. The drive assembly is connected to the switching drive mechanism.
[0012] In a preferred embodiment, the driving component includes: A sliding frame is fixedly mounted on one side of the second movable plate; A drive shaft, with a non-circular cross-section, is rotatably mounted on the first movable plate. One end of the drive shaft has an eccentrically mounted first drive post, which is slidably engaged within the slide frame. The mounting sleeve is rotatably mounted on the housing, and the switching drive mechanism can drive the mounting sleeve to rotate. The transmission shaft slides through the mounting sleeve.
[0013] In a preferred embodiment, the switching drive mechanism includes: The switching base is slidably mounted on the housing, and the drive motor is fixedly mounted on the switching base; A control component is disposed on the switching base and connected to the toggle block to convert the sliding of the toggle block into driving the switching base to slide and lock. The first active gear is rotatably mounted on the switching seat and connected to the output shaft of the drive motor via a synchronous belt drive unit. A second active gear is coaxially connected to one side of the first active gear. A first driven gear disc is rotatably mounted on the housing and can mesh with a first driving gear disc. The first driven gear disc is connected to the mounting wheel via a first bevel gear pair. The second driven gear disk is rotatably mounted on the housing and can mesh with the second driving gear disk. The second driven gear disk is connected to the mounting sleeve through a second bevel gear pair.
[0014] In a preferred embodiment, the control component includes: An inclined track is mounted on the switching seat, and both ends of the inclined track are connected to a first straight track; and The second drive column is disposed on the paddle block and is slidably engaged within one of the first straight tracks.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.
[0022] Example: like Figure 1 , 2 As shown in Figures 3 and 8, this invention provides a post-cardiovascular interventional therapy relief device, comprising a housing 1, a drive motor 21 mounted on the housing 1, an airbag 3 fixedly mounted inside the housing 1 via a mounting plate 2, the airbag 3 having multiple sets of gaps, a slidable lever 28 mounted on the housing 1, and a pumping mechanism on the housing 1 for circulating and deflating the airbag 3. The pumping mechanism includes a piston cylinder 4 fixedly mounted on the housing 1, the piston cylinder 4 communicating with the airbag 3, a piston rod 8 slidably mounted inside the piston cylinder 4, a mounting wheel 6 rotatably mounted on the housing 1, one end of a drive rod 7 being eccentrically hinged to the mounting wheel 6, and the other end being hinged to the piston rod 8. A guide seat 33 is provided on the housing 1, the piston rod 8 slidably passing through the guide seat 33, and an elastic element 32 is provided between the end of the piston rod 8 and the guide seat 33.
[0023] The device's housing 1 is made of medical-grade ABS material, with an airbag 3 fixed inside via a mounting plate 2. The airbag 3 is made of elastic silicone. A groove is formed on the outer wall of the housing 1, and a lever 28 is slidably embedded within it. When the mounting wheel 6 rotates, it pulls the piston rod 8 back and forth via a drive rod 7, achieving the cyclic pumping and deflating of the airbag 3 and compressing the elastic element 32. When the mounting wheel 6 loses external force, the piston rod 8 is reset under the action of the elastic element 32, ensuring that the airbag is not inflated during other forms of relaxation, thus avoiding interference with these methods. During cyclic pumping and deflating, the airbag 3 applies pressure and relaxes the limb, providing a relatively gentle relaxation.
[0024] like Figure 2 , 4As shown in Figure 5, in this embodiment, a first movable plate 11 is slidably disposed inside the housing 1 along the direction towards the inside of the housing 1. A massage mechanism is disposed on the first movable plate 11. The paddle block 28 is fixedly connected to the first movable plate 11 by a connecting rod 30, which is slidably inserted through the housing 1. The massage mechanism includes a second movable plate 12 slidably disposed on one side of the first movable plate 11 along the axis of the housing 1. Multiple sets of massage rollers 13 are disposed inside the second movable plate 12. The massage rollers 13 can extend into the gaps opened on the airbag 3. A drive assembly connected to the second movable plate 12 is disposed on the housing 1. The drive assembly drives the second movable plate 12 to reciprocate. The drive assembly is connected to a switching drive mechanism. The drive assembly includes a slide frame 14 fixedly mounted on one side of the second movable plate 12, a drive shaft 15 rotatably mounted on the first movable plate 11, a first drive column 16 eccentrically mounted on one end of the drive shaft 15, the first drive column 16 being slidably engaged in the slide frame 14, and an mounting sleeve 17 rotatably mounted on the housing 1, the drive shaft 15 being slidably inserted into the mounting sleeve 17.
[0025] Pushing the lever 28 causes the first movable plate 11 to slide along the axis of the housing 1, allowing the massage roller 13 to automatically contact the patient's skin without requiring separate adjustment of its position. The second movable plate 12 is slidably connected to the first movable plate 11 via a slide rail. The massage roller 13 is evenly mounted on the inner wall of the second movable plate 12 via a rotating shaft. The outer diameter of the massage roller 13 matches the gap width on the airbag 3, ensuring smooth insertion. The rotation of the mounting sleeve 17 drives the drive shaft 15 to rotate. During rotation, the drive shaft 15, through the cooperation of the first drive column 16 and the sliding frame 14, causes the second movable plate 12 to slide back and forth inside the first movable plate 11, thus massaging the patient's limbs. The sliding arrangement of the drive shaft 15 and the mounting sleeve 17 ensures that the sliding of the first movable plate 11 also transmits the sliding motion of the mounting sleeve 17 to the second movable plate 12.
[0026] like Figures 6 to 9 As shown, in this embodiment, a switching drive mechanism is provided on the housing 1. The switching drive mechanism converts the sliding of the lever 28 into a control that allows the drive motor 21 to selectively connect to the pumping mechanism and the massage mechanism. The mounting wheel 6 is connected to the switching drive mechanism, which can drive the mounting wheel 6 to rotate and can also drive the mounting sleeve 17 to rotate. The switching drive mechanism can only control the movement of one of the mounting wheel 6 and the mounting sleeve 17 individually, avoiding conflict between the gentle pressing mode and the rolling massage mode of the massage wheel 13, which could cause injury to the patient's limbs and improves the safety of the device during use.
[0027] like Figure 6 , 7As shown, in this embodiment, the switching drive mechanism includes a switching seat 20 that is slidably disposed on the housing 1, a drive motor 21 that is fixedly disposed on the switching seat 20, and a control component that is connected to the toggle block 28 on the switching seat 20. The control component converts the sliding of the toggle block 28 into driving the switching seat 20 to slide and lock. The control component includes an inclined rail 25 disposed on the switching seat 20. Both ends of the inclined rail 25 are connected to a first straight rail 26. A second drive post 29 is disposed on the toggle block 28. The second drive post 29 is slidably locked in one of the first straight rails 26.
[0028] The second drive column 29 can be slid by moving the toggle block 28. During the sliding process, the second drive column 29 can control the sliding of the switching seat 20 by cooperating with the inclined rail 25. When the second drive column 29 slides into the first straight rail 26, the position of the switching seat 20 can be locked. In some embodiments, a spring can be added to one side of the switching seat 20. The spring pushes the switching seat 20 to slide in one direction, thereby increasing the friction between the first straight rail 26 and the second drive column 29 and preventing the switching seat 20 from sliding on its own.
[0029] like Figures 6 to 9 As shown, in this embodiment, the switching drive mechanism further includes a first active gear disk 22 rotatably mounted on the switching seat 20. The first active gear disk 22 is connected to the output shaft of the drive motor 21 via a synchronous belt drive part 31. A second active gear disk 23 is coaxially connected to one side of the first active gear disk 22. A first driven gear disk 9 is rotatably mounted on the housing 1. The first driven gear disk 9 can mesh with the first active gear disk 22. The first driven gear disk 9 is connected to the mounting wheel 6 via a first bevel gear pair 10. A second driven gear disk 19 is rotatably mounted on the housing 1. The second driven gear disk 19 can mesh with the second active gear disk 23. The second driven gear disk 19 is connected to the mounting sleeve 17 via a second bevel gear pair 18.
[0030] The first active gear plate 22 and the second active gear plate 23 can be slid by controlling the sliding of the switching seat 20. When the first active gear plate 22 is engaged with the first driven gear plate 9, the mounting wheel 6 is rotated through the first bevel gear pair 10, thereby controlling the operation of the air pump mechanism to provide gentle pressure and relief to the limbs. After the switching seat 20 slides, the first active gear plate 22 disengages from the first driven gear plate 9, and the second active gear plate 23 is engaged with the second driven gear plate 19. The mounting sleeve 17 is rotated through the second bevel gear pair 18, and the massage wheel 13 comes into contact with the patient's limbs. This allows the massage wheel 13 to roll on the surface of the patient's limbs to provide a stronger massage, enabling free switching between multiple massage modes to suit patients with different pressure levels or different recovery stages.
[0031] like Figure 3 ,6 As shown in Figures 7 and 8, in this embodiment, two sets of inclined tracks 25 are provided, and the two sets of inclined tracks 25 are connected by a second straight track 27. Both ends of the switching seat 20 are provided with control switches 24 electrically connected to the drive motor 21. Two sets of stops 5 are provided on the housing 1, and the switching seat 20 is positioned between the two sets of stops 5. After the switching seat 20 slides, it abuts against the control switches 24 through the stops 5, thereby starting the drive motor 21 without requiring separate control, saving time and effort. Furthermore, during the sliding process, the second drive column 29 can also slide into the second straight track 27, thereby controlling the switching seat 20 to be in the middle position without triggering any set of control switches 24, facilitating quick and easy stopping of operation.
[0032] Specific usage and beneficial effects of the present invention: When in use, the device is fitted onto the patient's limb and the drive motor 21 is activated. The sliding of the lever 28 can be switched via a drive mechanism to selectively connect the drive motor 21 to either a pumping or massage mechanism. Patients can quickly switch operating modes by sliding the lever 28 according to their tolerance. When the drive motor 21 is connected to the pumping mechanism, the pumping mechanism circulates air into and deflates the airbag 3. The airbag 3 expands and contracts to provide gentle pressure and relief to the postoperative site, promoting blood circulation while avoiding excessive stimulation. When switched to the massage mechanism, the massage component extends into the gaps in the airbag 3 to provide rolling massage, specifically relieving muscle tension and meeting the relief needs of different patients. This compact design and convenient switching operation, requiring no additional tools, effectively solves the problem of insufficient practicality of existing devices, adapts to the personalized relief needs of patients after cardiovascular interventional procedures, and improves the clinical applicability and ease of use of the device.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
