Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a restraint and fixation device for the puncture-side limb after cardiovascular and cerebrovascular interventional procedures. Background Technology

[0002] The puncture site for interventional cardiovascular and cerebrovascular procedures mainly depends on the type of surgery and the patient's vascular condition. The two most common sites are the radial artery at the wrist and the femoral artery at the groin. The radial artery puncture site is at the wrist, and postoperatively only pressure bandage is needed, with fewer local complications such as bleeding. The femoral artery puncture site is in the groin area at the groin, and it is usually used as an alternative when radial artery puncture fails. The distal radial artery puncture site is in the web area on the back of the hand, which is more comfortable and can also protect the radial artery at the wrist. After interventional cardiovascular and cerebrovascular procedures, appropriate restraint and immobilization of the limb on the puncture side is to prevent limb movement from causing bleeding, hematoma, or displacement of the compression device at the puncture site.

[0003] The patent application number CN202520941206.8 mentions "a lower limb immobilization and fixation device after vascular intervention". This patent solves the problem that in related technologies, the restraint strap only fixes the distal end of the limb and does not lock the hip and knee joints, which allows patients to indirectly move the puncture site by internal rotation of the hip joint or flexion of the knee joint.

[0004] However, current techniques for restraining the radial artery puncture site mostly involve directly fixing the forearm and the puncture site without restraining the distal end of the puncture site. This results in a lack of control over the degree and speed of bending when the patient's arm and fingers are bent, leading to excessive bending or too rapid bending that can cause traction on the radial artery puncture site, resulting in damage, bleeding, hematoma, or displacement of the compressor, which greatly affects the efficiency of postoperative recovery. Summary of the Invention

[0005] This invention provides a restraint and fixation device for the puncture side limb after cardiovascular and cerebrovascular interventional procedures. It can effectively solve the problem mentioned in the background art, where existing technologies mostly directly fix the forearm and puncture point when restraining the radial artery puncture point, without restraining the distal end of the puncture point. As a result, when the patient bends their arm and fingers, the bending range and speed are not controlled, leading to excessive bending and too rapid bending, which causes traction on the radial artery puncture point, resulting in damage, bleeding, hematoma, or displacement of the compressor, greatly affecting the efficiency of postoperative recovery.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a restraint and fixation device for the puncture side limb after cardiovascular and cerebrovascular intervention, comprising a fixation bag, a back-of-hand fitting bag sewn to one end of the fixation bag, a plurality of finger straps sewn at equal intervals to the top of the back-of-hand fitting bag, and a limit protection component provided at one end of the fixation bag.

[0010] According to the above technical solution, the guide and limiting post is installed through the top of the flat card limiting plate, and there are two guide and limiting posts.

[0011] According to the above technical solution, the vertical pressure limiting block is slidably connected to the rotating double ferrule, and the multi-protruding insertion block is inserted and installed inside the straight insertion fixing groove.

[0012] According to the above technical solution, a limited support component is provided at one end of the fixed bag; The support components include linked bag bindings; One end of the fixed binding bag is equipped with a linkage binding bag, and the tops of both the fixed binding bag and the linkage binding bag are sewn with moisture-absorbing and anti-slip pads. Several restrictive rings are sewn at equal intervals on one side of the bottom end of the fixed bag and the linked bag, and several pressure-limiting straps are sewn at equal intervals on the other side of the bottom end of the fixed bag and the linked bag. Both ends of the isolation operation bag are equipped with straightening cables, and one end of the straightening cable is clamped to a straightening pull plate.

[0015] According to the above technical solution, the longitudinal section of the anti-slip pad is arc-shaped, and one end of the clamping nut is attached to one end of the clamping and limiting ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a limiting component to restrict the movement of the fingers, wrist, and puncture site in a coordinated manner. When the patient flexes their fingers or moves their wrist, the traction mechanism, in conjunction with the elastic buffer and damping limiting structure, gradually restricts the movement of the fingers, reducing the traction effect on the wrist and radial artery puncture site caused by rapid flexion or large-amplitude movement of the fingers. This reduces the probability of puncture site bleeding, hematoma, and displacement of the hemostatic compressor, and improves the stability of the puncture site after surgery.

[0017] 2. This invention, by setting an adjustable clamping mechanism, can be adjusted according to the patient's wrist size and the position of the hemostatic compressor, so that the fixation device and the hemostatic compressor form a stable fit. While ensuring the reliability of fixation, it reduces the possibility of the hemostatic compressor loosening or shifting due to the patient's limb movement, improves the hemostatic fixation effect, and reduces the frequency of readjusting the hemostatic compressor during nursing.

[0018] 3. This invention provides coordinated support for the patient's forearm and upper arm by setting a limiting support component, and uses an elastic traction structure to limit excessive flexion of the elbow joint, enabling the patient to maintain a certain range of physiological activity. At the same time, it avoids excessive movement of the elbow and wrist joints, which would cause further traction on the puncture site. This is beneficial for postoperative recovery and improves the comfort and stability of the patient during the wearing process.

[0019] 4. This invention uses a combination of a binding bag, elastic limit, and buffer structure to ensure the fixation effect on the puncture side limb while taking into account the patient's wearing comfort. It can be used by patients of different body types, the structure is easy to install and adjust, and it is convenient for clinical medical staff to operate, thus having good clinical application value.

[0020] In summary, by combining the restraint and support components, pressure hemostasis can be achieved on the wrist at the radial artery puncture site, controlling the range of motion of the fingers, wrist, and elbow, as well as the rotation speed of the fingers and elbow. This stabilizes the wound location and hemostatic components, reducing damage caused by large proximal and distal movements, while ensuring that the patient can move slightly, stabilizing blood circulation in the arm and hand, and ensuring efficient and effective postoperative recovery. The integrated device is easy to operate and effectively restrains the patient's position, making it suitable for limb restraint and fixation on the puncture side during cerebrovascular interventional surgery in clinical centers.

[0026] The working principle and usage process of this invention: After the patient has undergone cardiovascular intervention surgery via the radial artery, the medical staff applies a tourniquet to the puncture site. During the tourniquet application, the medical staff slightly lifts the patient's arm and passes the traction restraint strap 420 through the double-card positioning block 419 to achieve a pre-connection between the fixed binding bag 1 and the flat card limiting plate 421. The fixed binding bag 1, the back-of-hand fitting bag 2, and the finger strap 3 are placed on the hospital bed, and the patient's fingers are passed through the finger strap 3, so that the patient's forearm is in contact with the moisture-absorbing anti-slip pad 502 on the inside of the fixed binding bag 1, and the back of the patient's hand is in contact with the back-of-hand fitting bag 2, achieving hand fitting connection and forearm pre-fitting treatment. The vertical limiting plate 402 is used to limit the verticality between the arm and the back of the hand, and the cushioning sponge block 403 is used for cushioning to improve the comfort of the wrapping. Next, the medical staff threaded the traction restraint band 420 through one end of the flat card limiting plate 421, and pulled the traction restraint band 420 according to the radial artery hemostasis position of the patient's wrist and the thickness of the patient's wrist, so that the pressure fixing block 423 was aligned and attached to the tourniquet. After the attachment was completed, the traction restraint band 420 was secured with high-strength Velcro 512, thereby positioning and restricting the flat card limiting plate 421 and the pressure fixing block 423. Then, the multi-groove rotating block 424 was held, and the multi-groove rotating block 424 drove the pressure screw 422 to rotate, pushing the pressure fixing block 423 down along the guide limiting post 426, completely pressing the pressure fixing block 423 into the tourniquet position, and ensuring the stability of the tourniquet control by applying pressure. After pressing was completed, Pull the vertical pressure limiting block 429 and rotate the double ferrule 427 and the vertical pressure limiting block 429 along the guide limiting post 426, so that the multi-protrusion insertion block 430 moves to the position of the straight insertion fixing groove 425 at the top of the multi-groove rotating block 424. Then rotate the multi-protrusion insertion block 430 along the vertical pressure limiting block 429, and under the drive of the downward pressure spring 428, the vertical pressure limiting block 429 and the multi-protrusion insertion block 430 move down, inserting the multi-protrusion insertion block 430 into the inside of the straight insertion fixing groove 425. The multi-protrusion insertion block 430 and the vertical pressure limiting block 429 restrict the positioning of the multi-groove rotating block 424, thereby controlling the downward pressure screw 422 and preventing the downward pressure screw 422 from rotating due to bumps or unintentional accidental contact when the patient shakes their arm. After blood pressure control is completed, attach the linkage bag 501 and the moisture-absorbing anti-slip pad 502 to the upper arm, and pass the pressure-limiting strap 504 through the limiting ring 503. Use the pressure-limiting strap 504 to pull and fix the bag 1, causing the fixed bag 1 to rotate along the forearm and cover the forearm. Use the pressure-limiting strap 504 to pull the linkage bag 501, causing the linkage bag 501 to rotate along the upper arm and cover the upper arm. Use the high-strength Velcro 512 to attach and fix it, so that the fixed bag 1 is fixed to the forearm and the linkage bag 501 is fixed to the upper arm. After the overall fixation is completed, pass the tension limiting strap 511 through the load-bearing clamp 510, and fit the combination snap sleeve 513 with the tension limiting strap 511. Rotate the pressing bolt 514 to press and fix the bag. Bolt 514 drives the pressing and limiting plate 515 to move along the combination snap sleeve 513, and the pressing and limiting plate 515 presses and fixes the combination snap sleeve 513 and the traction limiting band 511. After fixation, the traction limiting band 511 is fixed by high-strength Velcro 512. The traction limiting band 511 is used to reinforce the outer end of the fixed binding bag 1. Then, the double convex combination block 516 is rotated, and the clamping limiting ring 517 is rotated along the double convex combination block 516. The clamping limiting ring 517 is placed at the position of the bed armrest. The pressing bolt 519 and pressing nut 520 are used to press and limit the two clamping limiting rings 517. The arm is fixed 6 hours after the puncture using the hoisting support to prevent the arm from shaking significantly. During the puncture restraint process, rotate the pressing screw 422 every 1 to 2 hours to gradually loosen the pressing fixing block 423 and the tourniquet. After hemostasis is completed, remove the flat card limiting plate 421 from the fixing bag 1 and the traction limiting strap 511 from the fixing bag 1. Place the fixing bag 1 and the arm on the hospital bed. At this time, the patient can lift the forearm slightly. When lifting the forearm, the isolation operation bag 404 pulls the straightening cable 505, which drives the straightening traction plate 506 to move along the guide isolation sleeve 508. At this time, the straightening traction plate 506 drives the distance spring rod 507 to move. The elasticity of the distance spring rod 507 slows down the lifting speed of the forearm and, together with the straightening cable 505, controls the bending angle between the forearm and the upper arm. The flexible buffer column 509 protects the elbow and controls the rotation angle between the patient's forearm and upper arm to avoid excessive traction that could cause tearing of the puncture site. The patient moves synchronously by bending the finger strap 3, the back-of-hand fitting bag 2, and the traction combination rope 405. The traction combination rope 405 pulls the traction cable 418 along the isolation operation bag 404, and the traction cable 418 pulls the take-up fixing frame 407 to rotate along the fixed processing box 401. The take-up fixing frame 407 drives the transmission gear 408 to rotate. At the same time, the torsion spring 406 is compressed, and the transmission gear 408 pushes the driven gear 410 to rotate. The driven gear 410 drives the combined centrifugal disc 409 to rotate. During the slow bending of the finger, the elastic limiting force of the return spring rod 411 affects the centrifugal disc. The insertion block 412 restricts movement, allowing the traction cable 418 to move steadily along the fixed processing box 401. When the finger bends significantly, the traction cable 418 pushes the movable pulley 416, which in turn drives the flat-push limiting frame 415 and the push-limit damping block 417 to move towards the take-up fixing frame 407. At this point, the flat-push spring rod 414 is compressed, and the push-limit damping block 417 presses against one end of the take-up fixing frame 407, thus locking the take-up fixing frame 407 in place and preventing excessive finger bending from causing a small-amplitude bend in the wrist, which would result in a large-amplitude pull on the radial artery puncture site. During finger repositioning, the torsion spring 406 drives the take-up fixing frame 407 to rotate and take up the traction cable 418. In conjunction with the push spring rod 414, the push limiting frame 415, the movable pulley 416, and the push limiting damping block 417 are driven to reposition. When the patient quickly bends the finger, the take-up fixing frame 407 and the transmission gear 408 quickly push the driven gear 410. Through the gear differential ratio, the driven gear 410 and the combined centrifugal disc 409 rotate synchronously and quickly, generating centrifugal force. The centrifugal force is greater than the repositioning spring rod 411. At this time, the centrifugal insertion block 412 is pushed into the inside of the multi-hole insertion ring 413, thereby quickly locking and limiting the combined centrifugal disc 409 to avoid traction damage to the radial artery puncture site caused by excessive finger movement.
