Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an adaptive pressure hemostatic restraint device after cardiovascular intervention. Background Art

[0002] With the continuous advancement of medical technology, cardiovascular interventional surgery has become an important means of treating a variety of cardiovascular diseases. This type of surgery has the advantages of less trauma, faster recovery, and significant efficacy, benefiting more and more patients. However, the problem of hemostasis at the puncture site after surgery has always been a focus of clinical attention. For example, after cardiac catheter interventional surgery, angioplasty and other operations, effective hemostasis treatment is required at the vascular puncture site to prevent complications such as bleeding and hematoma formation, and to ensure the patient's postoperative safety and recovery process:

[0003] After the cardiovascular interventional procedure, the device can accurately apply appropriate pressure to the vascular puncture site, closing the blood vessel at the puncture site by compression, preventing further blood flow, thereby achieving rapid and effective hemostasis, reducing the risk of postoperative bleeding, and avoiding serious complications such as local hematoma and hemorrhagic shock caused by bleeding:

[0004] When stopping bleeding from a patient's wound, the patient's arms vary in thickness, so the device's tightening and pressing pressure needs to be adjusted. However, existing devices are not convenient for automatically adjusting the tightening and pressing force according to the thickness of the patient's arms. When facing patients with thinner arms, the device's pressing force will be smaller, resulting in reduced hemostatic effect. Therefore, we proposed an adaptive pressure hemostatic restraint device for post-cardiovascular intervention.

When the L-plate 407 moves, it will move with the arc plate 410, and then the arc plate 410 will move with the rubber pad 411. When the rubber pad 411 moves, it will clamp the patient's arm, which can effectively prevent the device from sliding on the arm.

[0040] A specific application of this embodiment is:

[0041] When the staff needs to use the device, they first pull the U-shaped plate 210. When the U-shaped plate 210 moves, the two sliding rods 209 move with it. When the sliding rods 209 move, the microporous rubber plate 212 moves with it. When the microporous rubber plate 212 moves, the spring 211 is squeezed. Then the microporous rubber plate 212 is moved into the storage groove 207. After moving in, the patient's arm is inserted between the strap 201 and the support plate 1. As the patient's arm enters, the strap 201 gradually expands. When the strap 201 expands, the strap 201 moves on the shaft 203, making the strap 201 gradually longer. When the strap 201 moves, the shaft 203 rotates. When the shaft 203 rotates, it rolls up with the coil spring 205, and then the patient's wound is wound. When the arm 202 is in the proper position, the spring 205 will expand, and the shaft 203 will rotate when the spring 205 expands. When the shaft 203 rotates, the strap 201 will be tightened, and the device will be fixed to the patient's arm through the strap 201, so that the device can adapt to the thickness of the patient's arm. After the fixation is completed, the U-shaped plate 210 can be loosened. After the U-shaped plate 210 is loosened, the spring 211 will squeeze the microporous rubber plate 212, so that the microporous rubber plate 212 will move. When the microporous rubber plate 212 moves, it will carry the sliding rod 209 to slide in the circular groove 208. When the microporous rubber plate 212 moves, it will press the patient's wound to prevent bleeding from the patient's wound. Then, the microporous rubber plate 212 is squeezed by the spring 211. 12 keeps pressing the patient's wound to prevent the microporous rubber plate 212 from loosening when pressed. After the device is pressed, the threaded rod 2 404 can be rotated. When the threaded rod 2 404 rotates, it will move with the support block 402. When the support block 402 moves, it will slide with the slider 2 401 in the slide groove 101. At the same time, when the support block 402 moves, the round rod 406 will slide in the inclined groove 405. As the support block 402 moves, the round rod 406 will gradually change its position. When the round rod 406 changes its position, the L plate 407 will also change. At the same time, when the L plate 407 changes its position, it will slide on the U-shaped rod 409. At the same time, the U-shaped rod 409 limits the L plate 407 to prevent the L plate 407 from shaking when it moves. The arc plate 410 moves, and then the rubber pad 411 moves with the arc plate 410. When the rubber pad 411 moves, it clamps the patient's arm. By clamping the patient's arm, the device is kept at the wound of the patient's arm to prevent the device from being displaced. When the medical staff needs to disinfect the patient's wound, they can first rotate the butterfly valve 304. When the butterfly valve 304 rotates, the disinfectant is poured into the medicine box 302 from the medicine inlet pipe 303. After the disinfectant is poured, the butterfly valve 304 is rotated again to seal the medicine inlet pipe 303 to prevent the disinfectant from flowing out of the medicine inlet pipe 303. Then, the threaded rod 306 is rotated. When the threaded rod 306 rotates, the threaded block 314 moves. Then, when the threaded block 314 moves, the two joint shafts 307 move.When the joint shaft 2 307 moves, it will bring the connecting rod 308 to move in an arc shape. When the connecting rod 308 moves, it will bring the joint movable shaft 309 to move. Then the joint movable shaft 309 brings the slider 310 to slide in the slide rail 311. When the slider 310 moves, it will bring the rubber waterproof pad 312 to slide in the slide rail 311. At the same time, the rubber waterproof pad 312 will slide along the limit plate 313. Then the rubber waterproof pad 312 will be removed from the medicine outlet pipe 305. After removal, the disinfectant in the medicine box 302 will flow out from the medicine outlet pipe 305. When the disinfectant flows out, it pulls the U-shaped plate 210. When the U-shaped plate 210 moves, it will bring the sliding rod 209 to move. Then the sliding rod 209 brings the microporous The rubber plate 212 moves, and the microporous rubber plate 212 squeezes the spring 211, and then moves the microporous rubber plate 212 upwards. When the microporous rubber plate 212 moves, it moves the supporting leg 301, and then the supporting leg 301 moves with the medicine box 302. When the medicine box 302 moves, the medicine outlet pipe 305 also moves, so that the medicine outlet pipe 305 and the wound are kept at a certain distance, and then the disinfectant will flow into the wound, and then the disinfectant will disinfect the patient's wound. After the disinfection is completed, the U-shaped plate 210 is released. After the release, the parts are reset by the spring 211, so that the microporous rubber plate 212 presses the wound again, making it convenient for medical staff to disinfect the wound.
