Description

Technical Field

[0001] This invention relates to postoperative nursing equipment technology for cerebrovascular intervention, specifically to a multifunctional device for lower limb compression fixation and anti-thrombosis after cerebrovascular intervention. Background Technology

[0002] Lower limb compression and immobilization after cerebrovascular interventional surgery (often via the femoral artery or other lower limb vessels) is a crucial nursing procedure. Its core principle is to apply continuous and even pressure to the puncture site and surrounding tissues using appropriate external force. The aim is to prevent bleeding at the puncture site, reduce hematoma formation, and simultaneously immobilize the affected limb for a short period to avoid displacement due to compression, which could compromise hemostasis. This procedure requires a balance between the pressure intensity and duration, ensuring hemostasis while avoiding excessive pressure that could lead to local tissue ischemia, hypoxia, and necrosis. It is an important nursing measure to reduce the risk of postoperative bleeding and ensure patient recovery.

[0003] Current compression methods often involve directly applying a 1-kilogram saline bag to the fixed puncture site. However, the pressure of the saline bag is difficult to control and maintain, and there is a lack of quantitative adjustment methods. Excessive pressure can easily lead to ischemic necrosis of the local tissue around the puncture site. Medical staff cannot directly observe the wound condition and can only blindly predict whether there is bleeding at the puncture site and whether the compression is effective based on whether the saline bag slips or the dressing leaks. This not only interferes with the continuous compression effect but may also pull on the puncture site, aggravating the injury and increasing the risk of infection. The operation is cumbersome and poses safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional device for lower limb compression fixation and anti-thrombosis after cerebrovascular intervention, in order to solve the problems of difficult pressure control of saline bags, frequent disassembly and observation, easy interference with the compression effect, and increased risk of infection in the prior art.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 To be continued Figure 4 As shown:

[0030] Example 1:

[0031] This invention provides a multifunctional device for lower limb compression fixation and anti-thrombosis after cerebrovascular intervention, comprising a sleeve 1 with a zipper 11, a crotch sleeve 2 at one end of the sleeve 1, a connecting frame 3 at the other end of the sleeve 1, a base plate 4 rotatably connected to the connecting frame 3, and a footrest 5 on the base plate 4. A compression component 6 is located at the end of the sleeve 1 near the crotch sleeve 2. The sleeve 1 is made of medical-grade flexible and breathable material, adaptable to patients with different leg shapes, and serves as a mounting base for the compression component 6, the pressure component 7, and the ankle pump motion component 8. It also wraps around the patient's leg, achieving overall fixation of the affected limb, reducing the risk of bleeding at the puncture site due to postoperative limb movement, and providing both protection and support. The zipper 11 is located on the side of the sleeve 1 and is an openable design, facilitating quick donning and disassembly of the device without forcibly slipping it onto the affected limb, avoiding traction on the puncture site during donning. The tightness of the sleeve 1 can also be adjusted according to the patient's leg size, improving wearing comfort. The hip sleeve 2 is fixedly connected to one end of the sleeve 1, forming a ring-shaped structure that fits the hip. This is used to fix the device to the patient's hip, preventing the sleeve 1 from shifting or slipping during postoperative care. This ensures that the compression component 6 and the pressure component 7 act precisely on the target area, guaranteeing the stability of the nursing effect. The connecting frame 3 is made of high-strength lightweight alloy material, which provides a rotational support fulcrum for the base plate 4, allowing the base plate 4 to reciprocate around the connecting frame 3. This provides a motion basis for the ankle pump motion component 8, while ensuring the stability of the structural connection and preventing loosening during exercise. The base plate 4 is rotatably connected to the connecting frame 3, and a footrest 5 is fixed on top. This footrest 5 is used to transmit the driving force of the ankle pump motion component 8. By reciprocating its own rotation, the footrest 5 moves, thereby realizing the plantar flexion and dorsiflexion of the patient's ankle, while providing stable support for the foot and improving comfort during exercise. The footrest 5 is fixed on top of the base plate 4 to support the patient's foot, ensuring that the driving force is effectively transmitted to the ankle.

[0032] The compression assembly 6 includes a flip cover 61 rotatably connected to the sleeve 1. The flip cover 61 has a viewing window 611. A first inflatable bladder 62 is arranged annularly inside the flip cover 61. A first inflation tube 63 is connected to the first inflatable bladder 62. A transparent pressure plate 64 is provided at the bottom of the first inflatable bladder 62. A locking member 65 is provided on the flip cover 61 to lock the flip cover 61 onto the sleeve 1. The flip cover 61 is rotatably connected to the end of the sleeve 1 near the crotch sleeve 2, and adopts a flip-up structure, achieving compression through a flipping action. The opening and closing of the components facilitates precise alignment of the patient's device with the puncture point after donning it. It also provides a mounting base for the fluoroscopic window 611 and locking component 65, ensuring the overall integrity of the compression assembly 6. The fluoroscopic window 611, located in the center of the flip cover 61, is made of medical-grade high-transparency PC material and has sealing gaskets at the edges. It provides a visual observation channel for the puncture point, allowing medical personnel to clearly observe bleeding, hematoma, and effusion at the puncture point without disassembling the device, avoiding frequent disassembly that could interfere with the compression effect. The sealed design also prevents contaminants from entering the device. The first inflation balloon 62 is arranged in a ring shape. Inside the flip cover 61, an elastic sealing material is used. Pressure is generated through inflation to provide uniform and adjustable pressure to the transparent pressure plate 64. The annular design avoids the observation area corresponding to the viewing window 611, ensuring unobstructed vision. The first inflation tube 63 connects the first inflation bag 62 to an external air pump. Using flexible, pressure-resistant tubing, it provides a channel for inflating or deflating the first inflation bag 62, allowing medical personnel to precisely adjust the pressure of the first inflation bag 62 via the external air pump to meet the pressure requirements for hemostasis at different patient puncture sites. The transparent pressure plate 64 is fixed to the first... The bottom of the inflatable balloon 62 is made of medical transparent rigid material, which fits the puncture point area to evenly transmit the gas pressure of the first inflatable balloon 62 to the puncture point, achieving precise compression hemostasis. The transparent material, together with the viewing window 611 of the flip cover 61, ensures unobstructed observation of the puncture point. At the same time, the rigid structure avoids pressure dispersion and improves the hemostasis effect. The locking component 65 is used to lock the flip cover 61 onto the sleeve 1 to ensure that the compression component 6 maintains a stable position during hemostasis, preventing displacement of the compression component due to slight patient movement, and ensuring the continuity and stability of the compression pressure.

[0033] Sleeve 1 is placed on the patient's leg, hip sleeve 2 is placed on the patient's hip, and the patient's foot is placed in foot support 5. A transparent pressure plate 64 is pressed on the patient's femoral artery puncture site.

[0034] The locking component 65 includes a fixing plate 651 fixedly connected to the flip cover 61. A bolt 652 is threaded onto the fixing plate 651. The sleeve 1 has a slot 653 and a screw hole 654. The fixing plate 651 is fixedly connected to the edge of the flip cover 61. It engages with the slot 653 to achieve initial positioning of the flip cover 61 and the sleeve 1, providing a basis for subsequent bolt 652 tightening and ensuring precise alignment of the locking structure. The bolt 652, threaded onto the fixing plate 651 and made of medical-grade corrosion-resistant material, is screwed into the screw hole 654 of the sleeve 1, firmly locking the fixing plate 651 and the sleeve 1. The sleeve 1 is positioned to fix the flip cover 61. The slot 653 is located at the corresponding position of the sleeve 1 and is adapted to the shape of the fixing plate 651. It is used to accommodate the fixing plate 651, realize the quick positioning of the flip cover 61 and the sleeve 1, prevent the fixing plate 651 from shifting during the locking process, and improve the convenience and accuracy of the locking operation. The screw hole 654 is located at the bottom of the slot 653 and matches the thread specification of the bolt 652. It is used to provide a thread connection point for the bolt 652. Through the thread engagement between the bolt 652 and the screw hole 654, the fixing plate 651 is tightly fixed in the slot 653, ensuring the stability of the flip cover 61 after locking.

[0035] The fixing plate 651 is snapped into the slot 653, and the end of the bolt 652 is threaded into the screw hole 654.

[0036] Working principle: After surgery, the patient aligns the affected limb with sleeve 1, unzips 11, and puts sleeve 1 on the leg. At the same time, the hip sleeve 2 is put on the hip. The position of sleeve 1 is adjusted so that the puncture point is aligned with the lower part of the transparent window 611 of the flip cover 61. Zip 11 is pulled to fix sleeve 1. The flip cover 61 is flipped over so that it covers sleeve 1. At this time, the transparent pressure plate 64 on the inner side of the flip cover 61 is aligned with the patient's femoral artery puncture point. The fixing plate 651 on the flip cover 61 is inserted into the slot 653 of sleeve 1. The bolt 652 is rotated so that the threaded end of the bolt 652 is screwed into the screw hole 654 until the flip cover 61 is firmly locked, ensuring that the transparent pressure plate 64 is in close contact with the puncture point area. The first inflation tube 63 is connected to an external air pump. According to the patient's puncture... Set the target pressure for the puncture site, start the air pump to inflate the annular first air bladder 62. After the first air bladder 62 expands, it pushes the transparent pressure plate 64 to apply uniform pressure to the puncture site to achieve hemostasis. Medical staff can observe the puncture site for bleeding, hematoma or other abnormalities in real time through the viewing window 611 on the flip cover 61 and the transparent pressure plate 64. If the pressure is insufficient, the air can be supplemented by an external air pump. If the pressure position needs to be adjusted, the bolt 652 can be loosened, the position of the flip cover 61 can be finely adjusted and then locked again. After the preset hemostasis time is reached, the gas in the first air bladder 62 can be released by the external air pump, the bolt 652 can be loosened, the flip cover 61 can be flipped open, the zipper 11 can be pulled open, the sleeve 1 and the crotch sleeve 2 can be removed to complete the nursing operation.

[0037] By setting the compression component 6, the annular first inflation bladder 62, together with the first inflation tube 63, can be connected to an external air pump to achieve precise adjustment and stable maintenance of the compression pressure, which helps to reduce tissue damage or bleeding caused by abnormal pressure. The locking component 65, through the cooperation of the fixing plate 651, bolt 652, slot 653, and screw hole 654, firmly locks the flip cover 61 onto the sleeve 1 to prevent the compression component from shifting or slipping. The viewing window 611 on the flip cover 61 and the bottom transparent pressure plate 64 form a double transparent observation channel, allowing direct observation of the puncture point without removing the device, avoiding the interference of frequent disassembly on the compression effect. In addition, the zipper 11 and the crotch sleeve 2 design make wearing more convenient without pulling on the wound. The overall structure takes into account the accuracy of compression, the convenience of observation, and the stability of fixation, greatly improving the safety and efficiency of postoperative care.

[0038] Example 2:

[0039] As attached Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that a pressure assembly 7 is provided at one end of the sleeve 1 located on the patient's lower leg. The pressure assembly 7 includes a placement groove 71 fixedly connected to the inner wall of the sleeve 1. A second air bladder 72 is provided in the placement groove 71. The placement groove 71 is fixed to the inner wall of the sleeve 1 and is horizontally and evenly distributed to fix the position of the second air bladder 72, preventing the second air bladder 72 from shifting or stacking during inflation and pressurization, ensuring that multiple second air bladders 72 function in the preset position, and improving the uniformity of pressurization. The second air bladders 72 are placed in the placement groove 71, and multiple are horizontally distributed. They are made of elastic sealing material and apply segmented pressure to the patient's lower leg through intermittent inflation and expansion, simulating the physiological function of the intestinal pump, promoting venous return in the lower limbs, reducing the risk of deep vein thrombosis, and the low-intensity pulse mode can avoid affecting the hemostasis effect at the puncture point.

[0040] The pressurization assembly 7 also includes a second inflation tube 73 connected to the second inflation bladder 72. The end of the second inflation tube 73 away from the second inflation bladder 72 is connected to a connecting tube 74. An inflation port 75 is provided on the connecting tube 74. The second inflation tube 73 is used to connect the second inflation bladder 72 and the connecting tube 74. It adopts a flexible pressure-resistant tube material and multiple tubes are arranged in parallel to deliver gas to each second inflation bladder 72, so as to realize the synchronous or sequential inflation and deflation of multiple second inflation bladders 72 and ensure the coordination of the pressurization process. The connecting tube 74 is connected to multiple second inflation tubes 73 and is used to divert the gas from the external air pump to each second inflation tube 73, so as to realize the centralized control of multiple second inflation bladders 72 and simplify the inflation operation process. The inflation port 75 is used to connect to the external air pump to provide a gas source for the pressurization assembly 7.

[0041] The placement slot 71, the second air bag 72, and the second air tube 73 are all provided in multiple ways and are evenly distributed in a horizontal direction. The multiple second air tubes 73 are respectively connected to the connecting pipe 74.

[0042] Working principle: After the device is worn, the inflation port 75 of the pressurization component 7 is connected to the external air pump, ensuring that the connecting pipe 74 and each of the second inflation pipes 73 are properly connected, and that the second inflation bags 72 are all in the placement slots 71 without displacement. Based on the patient's lower limb condition, the external air pump is used to set the pressurization pressure, inflation time, deflation time, and cycle. The external air pump is then started, and gas enters the connecting pipe 74 through the inflation port 75, and then flows through multiple second inflation pipes 73 to each of the second inflation bags 72. The multiple second inflation bags 72 intermittently in a preset sequence. Inflation applies segmented pressure to the calf area, simulating the action of the intestinal pump to promote venous return in the lower limbs. During the deflation phase, the second inflatable bladder 72 contracts, restoring normal blood circulation in the lower limbs. This cycle repeats continuously. During the pressurization process, the puncture site is continuously monitored through the fluoroscopic window 611 to ensure that the pressurization operation does not affect hemostasis at the puncture site. If the patient experiences discomfort, the pressurization pressure can be adjusted or the pressurization can be paused through the external air pump. The operation can be resumed after the patient adapts. After the preset pressurization time is reached, the external air pump is turned off, and the gas in the second inflatable bladder 72 is released.

[0043] By setting up the pressurization component 7, multiple horizontally evenly distributed second inflation balloons 72 are centrally controlled through the connecting tube 74 and the inflation interface 75, which can achieve intermittent inflation and pressurization, accurately simulating the physiological function of the intestinal pump, promoting blood flow in the lower limbs, reducing the probability of deep vein thrombosis, and the segmented balloon design makes the pressurization more uniform, avoiding discomfort caused by local pressure concentration. The low-intensity pulse mode ensures the circulation promotion effect without interfering with the compression hemostasis of the puncture point. It has strong adaptability and can meet the lower limb care needs of different patients, improving the comprehensiveness and safety of postoperative care.

[0044] Example 3:

[0045] As attached Figure 6 To be continued Figure 8As shown, this embodiment is basically the same as the previous embodiment, except that an ankle pump motion component 8 is provided at the end of the sleeve 1 near the footrest 5. The ankle pump motion component 8 includes a base 81 fixedly connected to the sleeve 1, a motor 82 fixedly connected to the base 81, a turntable 83 fixedly connected to the output end of the motor 82, a lever 84 installed on the turntable 83, and a drive groove 85 opened on the base plate 4. The base 81 is fixed to the end of the sleeve 1 near the footrest 5 and is made of rigid material. It is used to provide a fixed mounting base for components such as the motor 82 and the turntable 83, ensuring the structural stability of the ankle pump motion component 8 and preventing components from loosening or shifting during exercise. The motor 82 is fixed to the base 81 and is used to provide the driving force required for ankle pump movement. By rotating the output end, it drives the turntable 83 to rotate, thereby driving the entire ankle pump motion mechanism to operate. Its speed and... The steering can be adjusted via an external control device to adapt to different motion mode requirements. The turntable 83 is fixed to the output end of the motor 82 and is used to transmit the rotational power of the motor 82. The rotational motion is converted into the reciprocating rotation of the base plate 4 through the eccentrically set lever 84. At the same time, it provides multiple mounting positions for the lever 84 to realize the adjustment of the motion angle. One end of the lever 84 is inserted into the drive groove 85, and the other end is threaded to the insertion hole 87 of the turntable 83. It adopts a rigid rod structure to convert the rotational motion of the turntable 83 into the swinging motion of the base plate 4, driving the base plate 4 to reciprocate around the connecting frame 3, thereby driving the patient's ankle to move. The drive groove 85 is opened on the base plate 4 to provide a guiding space for the movement of the lever 84. When the turntable 83 drives the lever 84 to rotate, the lever 84 slides in the drive groove 85 and pushes the base plate 4 to swing, ensuring the smoothness of motion transmission.

[0046] The ankle pump motion assembly 8 also includes a slot 86 and a socket 87 on the turntable 83. The slot 86 on the turntable 83 provides space for the installation and adjustment of the lever 84, allowing the lever 84 to move along the slot 86 on the turntable 83 to fit the installation position of different sockets 87, making it convenient for medical staff to adjust the eccentricity of the lever 84. The socket 87 provides multiple mounting positions for the lever 84. By installing the lever 84 in the sockets 87 at different heights, the eccentricity between the lever 84 and the center of the turntable 83 is changed, thereby adjusting the rotation angle of the base plate 4 and the footrest 5 to suit the exercise needs of different patients.

[0047] One end of the lever 84 is inserted into the drive slot 85, and the other end of the lever 84 passes through the slot 86 and is threaded into the insertion hole 87. The lever 84 is set as an eccentric shaft on the turntable 83. Multiple insertion holes 87 are provided and are evenly distributed along the vertical direction.

[0048] Working principle: Based on the patient's postoperative recovery, determine the ankle pump's movement angle, loosen the fixing thread of the lever 84, move the lever 84 along the slot 86 of the turntable 83, select a suitable height for the insertion hole 87, screw the threaded end of the lever 84 into the insertion hole 87 and lock it, completing the movement angle adjustment. The higher the position of the insertion hole 87, the greater the eccentricity of the lever 84, and the greater the rotation angle of the base plate 4. Connect the power supply to the motor 82, set the speed, direction, and running cycle of the motor 82 to ensure that the movement frequency and duration are suitable for the patient's tolerance, start the motor 82, and the output end of the motor 82 drives the turntable 83 to rotate. Because the lever 84 is eccentrically mounted on the turntable 83... 3. The lever 84 is inserted into the drive groove 85 of the base plate 4. When the turntable 83 rotates, the lever 84 slides in the drive groove 85 and pushes the base plate 4 to reciprocate around the fulcrum of the connecting frame 3. The base plate 4 drives the foot support 5 above to move synchronously. The foot support 5 pulls the patient's foot to perform alternating plantar flexion and dorsiflexion movements to realize automated ankle pump movement. During the movement, the status of the puncture point, the patient's lower limb comfort and the stability of the device are monitored simultaneously. If there is an abnormality in the puncture point, patient discomfort or device displacement, the motor 82 is immediately stopped, adjusted and then resumed. The movement angle, frequency and pressure parameters can be gradually adjusted according to the patient's recovery progress.

[0049] By incorporating the ankle pump motion component 8, the automated design driven by the motor 82 eliminates the need for active patient cooperation. This is particularly suitable for patients who are weak after surgery and unable to move independently. It allows for stable ankle pump exercises, enhancing blood circulation and muscle activity, and preventing joint stiffness. The coordination between the lever 84 and the multi-position socket 87 on the turntable 83 allows for flexible adjustment of the movement angle by changing the eccentricity, adapting to different postoperative recovery stages and limb conditions of patients. The motion transmission is achieved through the precise coordination between the lever 84 and the drive slot 85, ensuring stable operation without deviation. Furthermore, it does not interfere with the compression and pressurization components 7, working synergistically to enhance the nursing care effect, improve the effectiveness of rehabilitation assistance, reduce the operational burden on medical staff, and significantly improve the postoperative rehabilitation experience and recovery efficiency for patients.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
