Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hand recovery device after coronary angiography. Background Technology

[0002] Coronary angiography is an important interventional procedure used to diagnose coronary artery disease. During the procedure, a catheter is inserted into the coronary artery system through an artery in the wrist (usually the radial artery) to inject contrast agent, which visualizes the morphology and blood flow of the coronary arteries. Because arterial puncture disrupts the integrity of the vessel wall, if effective hemostasis is not performed post-procedure, it can lead to significant bleeding at the puncture site, hematoma formation, and even more serious bleeding complications such as hemorrhagic shock. Therefore, applying pressure to the wrist artery for hemostasis is a crucial step after coronary angiography.

[0003] This type of pressure-based hemostasis is often quite tight, which can cause cyanosis of the hand, and the pressure should not be loosened during this period. Because prolonged pressure can affect blood circulation in the hand, in order to avoid serious complications such as ischemic necrosis, it is necessary to restore blood circulation through hand movement. Generally, the patient is required to actively move their hand, or a family member can continuously assist the patient in moving their hand. This process may last for several hours, which is time-consuming, laborious, and has little effect, making it difficult to achieve the desired results. Utility Model Content

[0004] The purpose of this invention is to provide a hand recovery device after coronary angiography to solve the problems existing in the prior art, help patients carry out postoperative recovery activities, exercise the joints of the fingers, train the mobility of the fingers, and ensure the range of motion, so as to effectively help patients actively and proactively carry out self-rehabilitation training.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A hand recovery device after coronary angiography includes a back of the hand plate, a palm plate, and at least one set of finger assemblies. Both the back of the hand plate and the palm plate are equipped with a rotation drive device. Each finger assembly includes a first finger sleeve, a second finger sleeve, ..., an Nth finger sleeve connected sequentially by a rotating shaft, where N is an integer greater than or equal to two. The second to Nth finger sleeves each have wire holes along their length on both their upper and lower surfaces. Traction wires extend from both the upper and lower sides of the first finger sleeve. These traction wires pass through the wire holes on the corresponding sides of the second to Nth finger sleeves and connect to the rotation drive device on the corresponding side. The rotation drive device controls the traction wires to cause the finger assembly to curl and extend.

[0007] In one exemplary embodiment, the device further includes a connector, and the number of finger assemblies is at least two sets. The end of the Nth finger sleeve away from the first finger sleeve is connected to the pivot of the connector, and the connector has a through hole for a finger to pass through and enter the finger assembly.

[0008] In one exemplary embodiment, the rotary drive device includes a drive motor and a winding assembly. The drive motor is disposed on the back of the hand or the palm of the hand, the winding assembly is disposed at the output end of the drive motor, and the traction line is connected to the winding assembly.

[0009] In an exemplary embodiment, the winding assembly includes a drive gear, a driven gear, a winding section, and a first fixing section. The drive gear is mounted on the output end of the drive motor. Each traction line corresponds to a driven gear that meshes with the drive gear. The driven gear is rotatably mounted on the first fixing section via a rotating shaft. The first fixing section is mounted on the back of the hand or the palm of the hand. The winding section is fixedly connected to the driven gear. One end of the traction line is fixedly connected to the winding section. The winding section rotates axially under the drive of the driven gear, and drives the traction line to wind onto the winding section.

[0010] In an exemplary embodiment, the driven gear has a circumferential groove for receiving the traction line, and the bottom surface of the groove forms the winding portion around the axis of the driven gear.

[0011] In one exemplary embodiment, the system further includes a displacement mechanism for controlling the driven gear to engage or disengage from the driving gear.

[0012] In an exemplary embodiment, a second fixing part is fixedly provided on the back plate of the hand and the palm plate of the hand, and the first fixing part is mounted on the second fixing part by a displacement mechanism, and each driven gear corresponds to one first fixing part.

[0013] In an exemplary embodiment, the displacement mechanism includes a nut and a screw that cooperate with each other. The nut is fixedly mounted on the second fixing part. One end of the screw is provided with a rotating part, and the other end of the screw passes through the second fixing part and is rotatably connected to the first fixing part. A limiting member for restricting the rotation of the first fixing part is also provided between the first fixing part and the second fixing part.

[0014] In one exemplary embodiment, the device further includes a pressure massage glove, which the patient puts on and inserts into the finger assembly; the pressure massage glove includes a hand-shaped airbag covering the patient's fingers and palm and an air pump communicating with the hand-shaped airbag, through which pressure is applied to the hand-shaped airbag to massage the hand.

[0015] In one exemplary embodiment, the hand-shaped airbag is divided into multiple independent inflation zones, and each inflation zone is connected to the air pump via an air tube.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] 1. This system comprises a back of hand plate, a palm plate, and at least one set of finger components. Both the back of hand plate and the palm plate are equipped with a rotation drive mechanism. The finger components include a first finger sleeve, a second finger sleeve, ..., an Nth finger sleeve connected sequentially by a rotating shaft, where N is an integer greater than or equal to two. The second to Nth finger sleeves have wire holes along their length on both their upper and lower surfaces. Traction wires extend from both the upper and lower sides of the first finger sleeve. These traction wires pass through the wire holes on the corresponding sides of the second to Nth finger sleeves and connect to the corresponding rotation drive mechanism. The rotation drive mechanism controls the traction wires to cause the finger components to curl and extend. During use, the patient inserts their finger into the finger component. The rotation drive mechanism on the palm plate rotates, contracting the traction wires on the palm side, thus causing the finger component to curl. The rotation drive mechanism on the back of hand plate rotates, contracting the traction wires on the back of the hand, thus causing the finger component to open. This process is repeated to achieve the repetitive curling and opening motion of the hand, assisting the patient in self-training. The rotation drive mechanism can also control the range of curling and opening to ensure the training effect.

[0018] Other technical solutions disclosed in this utility model also have the following technical advantages:

[0019] 2. A second fixing part is fixedly installed on the back of the hand and the palm of the hand. The first fixing part is installed on the second fixing part through a displacement mechanism. Each driven gear corresponds to one first fixing part. The displacement mechanism can be a nut and screw that cooperate with each other, or a miniature electric telescopic rod. It is used to control the engagement or disengagement of the driven gear with the driving gear. When rehabilitation training is needed for a certain finger, the corresponding displacement mechanism can be activated, so that the driven gear corresponding to that finger engages with the driving gear, allowing the drive motor to drive the traction wire to wind. The driven gear corresponding to a finger that does not need rehabilitation training is disengaged from the driving gear under the control of the displacement mechanism. When the drive motor rotates, it will not drive the corresponding traction wire to wind, thus achieving targeted training.

[0020] 3. By incorporating a pressure massage glove that includes a hand-shaped airbag and an air pump, pressure is applied to the hand-shaped airbag via the air pump to massage the hand. Furthermore, the hand-shaped airbag is divided into multiple independent inflation zones, each connected to the air pump via an air tube. During use, the opening and closing of each air tube is controlled by a solenoid valve to sequentially apply pressure, and the pressure in each zone is controlled by an adjusting valve. This allows for a sequential massage of the patient's hand from fingertips to palm, or from palm to fingertips, promoting blood flow. Different pressure values ​​can be adjusted according to the different pressure-bearing capacities of different areas. Attached Figure Description

[0033] The purpose of this invention is to provide a hand recovery device after coronary angiography to solve the problems existing in the prior art, help patients carry out postoperative recovery activities, exercise the joints of the fingers, train the mobility of the fingers, and ensure the range of motion, so as to effectively help patients actively and proactively carry out self-rehabilitation training.

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] Please refer to Figures 1 to 6 This embodiment provides a hand recovery device after coronary angiography, including a back of hand plate 1, a palm plate, and at least one set of finger components 3. Both the back of hand plate 1 and the palm plate are provided with a rotation drive device 2. The finger component 3 includes a first finger sleeve 6, a second finger sleeve 7, ..., an Nth finger sleeve 8 connected in sequence by a rotating shaft, where N is an integer greater than or equal to two. The second finger sleeve 7 to the Nth finger sleeve 8 are provided with wire holes along the length direction on both the upper and lower surfaces. The first finger sleeve 6 is provided with traction wires 4 on both the upper and lower sides. The traction wires 4 pass through the wire holes on the corresponding sides of the second finger sleeve 7 to the Nth finger sleeve 8 and are connected to the rotation drive device 2 on the corresponding side. The rotation drive device 2 is used to control the traction wires 4 to drive the finger component 3 to curl and extend.

[0037] When in use, after the patient puts on gloves, they insert their fingers into the finger assembly 3. The rotating drive device 2 on the palm plate rotates, contracting the traction line 4 on the palm side, which in turn causes the finger assembly 3 to curl up. The rotating drive device 2 on the back of the hand plate 1 rotates, contracting the traction line 4 on the back of the hand, which in turn causes the finger assembly 3 to open up. This is repeated to achieve the repetitive action of curling and opening the hand, thus assisting the patient in self-training. At the same time, the length of the traction line 4 of each finger can be controlled by the rotating drive mechanism to determine the degree of finger flexion and extension, thereby controlling the range of motion and ensuring the training effect.

[0038] Specifically, a fixing block is provided at the end of the first finger sleeve 6 away from the second finger sleeve 7, and one end of the traction line 4 is fixed to the fixing block. The number of fixing blocks can be one at the end, with the traction lines 4 on both the upper and lower sides fixed to this one fixing block; or there can be one at the top and one at the bottom, with the traction lines 4 on the upper and lower sides respectively fixed to the fixing blocks on the corresponding sides.

[0039] The number of finger components 3 can be set according to the actual number of fingers required for rehabilitation training. When there are at least two sets of finger components 3, a connector 5 is provided to connect them, achieving integration and easy portability. The connector 5 has a through hole for the finger to pass through and enter the finger component 3, and the end of the Nth finger sleeve 8 of the finger component 3 away from the first finger sleeve 6 is connected to the pivot of the connector 5.

[0040] The rotary drive device 2 includes a drive motor 10 and a winding assembly. The drive motor 10 is mounted on the back of the hand plate 1 or the palm of the hand, and the winding assembly is mounted on the output end of the drive motor 10. The traction line 4 is connected to the winding assembly.

[0041] The winding assembly includes a drive gear 11, a driven gear 12, a winding section 16, and a first fixing section 13. The drive gear 11 is mounted on the output end of the drive motor 10. Each traction line 4 corresponds to a driven gear 12 that meshes with the drive gear 11. The driven gear 12 is rotatably mounted on the first fixing section 13 via a rotating shaft. The first fixing section 13 is mounted on the back of the hand plate 1 or the palm plate. The winding section 16 is fixedly connected to the driven gear 12. One end of the traction line 4 is fixedly connected to the winding section 16. The winding section 16 rotates axially under the drive of the driven gear 12, causing the traction line 4 to wind onto the winding section 16.

[0042] Furthermore, to reduce the overall size of the winding assembly, a through slot for accommodating the traction wire 4 can be directly opened in the circumference of the driven gear 12. The bottom surface of the through slot forms a winding portion 16 around the axis of the driven gear 12, so that the traction wire 4 is directly wound in the middle of the driven gear 12.

[0043] As a preferred embodiment, the winding assembly further includes a displacement mechanism. The displacement mechanism is used to control the driven gear 12 to engage or disengage from the driving gear 11. When rehabilitation training is required for a certain finger, the displacement mechanism can be activated to engage the driven gear 12 corresponding to that finger with the driving gear 11, so that the drive motor 10 can drive the traction wire 4 to wind. The driven gear 12 corresponding to a finger that does not require rehabilitation training will disengage from the driving gear 11 under the control of the displacement mechanism. When the drive motor 10 rotates, it will not drive the corresponding traction wire 4 to wind, thereby achieving targeted training.

[0044] Specifically, a second fixing part is fixedly provided on the back plate 1 and the palm plate, and a first fixing part 13 is installed on the second fixing part through a displacement mechanism. Each driven gear 12 corresponds to a first fixing part 13.

[0045] The displacement mechanism includes a nut and a screw 14 that cooperate with each other. The nut is fixedly installed on the second fixed part. One end of the screw 14 is fixedly provided with a rotating part 15, and the other end of the screw 14 passes through the second fixed part and is rotatably connected to the first fixed part 13. A limiting member for restricting the rotation of the first fixed part 13 is also provided between the first fixed part 13 and the second fixed part, such as a telescopic rod with both ends connected to the first fixed part 13 and the second fixed part respectively, or a guide rod with one end fixed to the second fixed part and the other end passing through the through hole, etc. By rotating the rotating part 15, the first fixed part 13 rises or falls under the action of the nut and the screw 14. The screw 14 is rotatably connected to the first fixed part 13 and is provided with a limiting member to restrict the rotation of the first fixed part 13, which can ensure that the first fixed part 13 will not rotate under the drive of the screw 14, thus affecting the meshing of the driven gear 12 and the driving gear 11. In this embodiment, the second fixing part is configured as a shell 9 covering the back of the hand plate 1 and the palm plate, and the nut is configured as an internal threaded hole opened on the shell 9.

[0046] The displacement mechanism can also directly adopt a miniature electric telescopic rod. The fixed end of the miniature electric telescopic rod is fixedly connected to the second fixed part, and the movable end of the miniature electric telescopic rod is connected to the first fixed part 13. Buttons for controlling the corresponding miniature electric telescopic rod can be set on the palm plate and the back of the hand plate 1. Pressing a button controls the extension or retraction of the miniature electric telescopic rod, and the corresponding first fixed part 13 drives the corresponding driven gear 12 to engage with or disengage from the driving gear 11.

[0047] Example 2

[0048] Please refer to Figure 7 Based on Embodiment 1, this embodiment further includes a pressure massage glove 17. The pressure massage glove 17 includes a hand-shaped airbag 18 that covers the patient's fingers and palm, and an air pump 19 that communicates with the hand-shaped airbag 18. The air pump 19 applies pressure to the hand-shaped airbag 18 to massage the hand. In use, the patient first puts on the pressure massage glove 17 and then inserts it into the finger assembly.

[0049] As a preferred embodiment, the hand-shaped airbag 18 is divided into multiple independent inflation zones, and each inflation zone is connected to the air pump 19 through an air tube.

[0050] Specifically, such as Figure 7As shown, the hand-shaped airbag 18 is divided into a first inflation region 20, a second inflation region 21, and a third inflation region 22 from the fingertips to the palm. The first inflation region 20 is connected to the air pump 19 via a first air tube 23, the second inflation region 21 is connected to the air pump 19 via a second air tube 24, and the third inflation region 22 is connected to the air pump 19 via a third air tube 25. In this embodiment, the first inflation region 20 covers the fingertips of the five fingers, and the first air tube 23 is divided into five branches in the middle, each leading to the first inflation region 20 of the five fingers. Similarly, the second inflation region 21 covers the middle and base of the five fingers, and the second air tube 24 is divided into five branches in the middle, each leading to the second inflation region 21 of the five fingers. The third inflation region 22 is a single, continuous area covering the palm, and the third air tube 25 leads directly into the third region without branching.

[0051] During use, the opening and closing of each airway can be controlled by the solenoid valve to achieve sequential pressurization. The pressure of each area can also be controlled separately by the regulating valve to achieve sequential massage of the patient's hand from fingertips to palm or from palm to fingertips, promoting blood flow. Different pressure values ​​can be adjusted according to the different pressure-bearing capacities of each part.

[0052] It should be noted that this embodiment only provides one distribution scheme of the mutually independent inflatable areas. It can also include other arbitrary combinations of distribution schemes, such as the first inflatable area covering the first phalanx, the second inflatable area covering the second phalanx, the third inflatable area covering the third phalanx, etc., as well as the inflation method, such as the five fingertips of the five fingers being inflated independently, etc. The specific design can be freely made according to actual needs.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0055] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0056] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0057] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0058] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.

[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
