Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a bandage-assisted fixation device after cardiac interventional treatment. Background Technology

[0002] Cardiovascular interventional surgery is currently the main surgical treatment for heart diseases, such as transcatheter coronary artery stenting for coronary artery disease, radiofrequency ablation for arrhythmia, and valve replacement surgery for structural heart disease. Peripheral vascular surgery is the main approach for interventional surgery. Among them, the femoral artery and femoral vein are frequently chosen surgical vessels for coronary intervention. Due to the complex local anatomy and proximity to the groin area, the incidence of bleeding and infection is high when puncturing the femoral artery and femoral vein. Postoperatively, auxiliary fixation devices are usually required to compress and stop bleeding at the wound.

[0003] Current postoperative bandage fixation devices for cardiac interventional procedures typically involve applying sandbags for pressure bandaging, requiring the patient to lie flat for 24 hours for immobilization. During this period, the sandbags may shift, reducing the effectiveness of pressure hemostasis, or prolonged tape fixation may cause various discomforts such as skin allergies and itching.

[0004] Therefore, to address the problems of existing post-cardiac interventional treatment bandage fixation devices being prone to displacement, causing adverse reactions such as allergies with prolonged wear, and having low hemostasis efficiency, a post-cardiac interventional treatment bandage fixation device can be designed. This device features a structure that combines an auxiliary fixation compression bag and an adjustable fixation bandage. By fixing the conical sandbag, it can prevent the sandbag from sliding or shifting during the compression of the patient's wound, eliminating the need for the patient to remain lying flat. Furthermore, by placing an anti-allergy regional adhesive tape at the end of the adjustable fixation bandage that contacts the patient's skin, it can protect the patient's skin and increase comfort. This design not only improves hemostasis efficiency but also enhances comfort. Utility Model Content

[0005] In order to overcome the problems of existing postoperative bandage fixation devices for cardiac interventional treatment, which are prone to displacement, allergic reactions and other adverse reactions with long-term wear, and have low hemostasis efficiency.

[0006] The technical solution of this utility model is as follows: a bandage-assisted fixation device after cardiac interventional therapy, comprising an auxiliary fixation compression bag, a first adjustable fixation bandage, a second adjustable fixation bandage, a third adjustable fixation bandage, a fourth adjustable fixation bandage, a conical sandbag, anti-allergy regional adhesive tape, and a zipper. The auxiliary fixation compression bag contains a conical sandbag for applying pressure to the patient's wound to stop bleeding. A zipper is provided on the upper side of the auxiliary fixation compression bag for opening and closing, allowing the conical sandbag to be removed. First adjustable fixation devices are fixedly installed around the four corners of the auxiliary fixation compression bag to assist in securing it. The system includes a first adjustable bandage, a second adjustable bandage, a third adjustable bandage, and a fourth adjustable bandage. The first and third adjustable bandages are detachably connected and work together to secure the auxiliary compression bag. The second and fourth adjustable bandages are also detachably connected and work together to secure the auxiliary compression bag. The lower ends of the first, second, third, and fourth adjustable bandages, near the auxiliary compression bag, are all fitted with detachable anti-allergy regional adhesive tape to protect the patient's skin and improve patient comfort.

[0007] Preferably, the upper ends of the first and fourth adjustable bandages are fitted with first Velcro straps, and the lower ends of the second and third adjustable bandages are fitted with second Velcro straps.

[0008] Preferably, the first adjustable fixing bandage, the third adjustable fixing bandage, the fourth adjustable fixing bandage, and the second adjustable fixing bandage are all detachably connected to each other via a first Velcro and a second Velcro.

[0009] Preferably, the length of the bandage can be adjusted by connecting the first and second Velcro at different positions to accommodate different patients and different fixation needs.

[0010] Preferably, the lower ends of the first, second, third, and fourth adjustable bandages, near the auxiliary compression bag, are all fitted with a third Velcro for detachable connection with the anti-allergy regional adhesive tape, and the upper end of the anti-allergy regional adhesive tape is fitted with an adhesive structure corresponding to the third Velcro.

[0011] Preferably, the anti-allergy regional adhesive tape has multiple sets of silicone blocks evenly distributed and fixed from left to right on the end closest to the patient's skin to protect the patient's skin and increase their comfort. The silicone blocks have a first vent hole for increasing breathability, which is evenly distributed on the side of the silicone block closest to the patient's skin.

[0012] Preferably, the silicone block has second vent holes evenly distributed on its sides, corresponding to the first vent holes, and the first and second vent holes are interconnected.

[0013] The beneficial effects of this utility model are:

[0014] 1. An auxiliary fixation compression bag is used to hold a conical sandbag. This bag is secured by four adjustable bandages (first, second, third, and fourth), preventing the sandbag from slipping or shifting during wound compression. The patient does not need to remain lying flat. Anti-allergy adhesive tape at the skin-contacting end of the adjustable bandages protects the skin and increases comfort. This results in higher hemostasis efficiency and better comfort. The conical sandbag itself is an independently designed structure; if bleeding occurs after 6 hours of compression, it can be reused locally for further hemostasis, greatly improving the efficiency of compression hemostasis.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Interventional cardiac therapy is an important method for treating heart disease, mainly involving the following aspects:

[0024] I. Scope of Treatment:

[0025] Coronary artery disease: such as coronary artery stenosis or blockage, is treated through methods such as balloon angioplasty and stent implantation.

[0026] Congenital heart diseases, such as patent ductus arteriosus and pulmonary valve stenosis, can be treated with interventional procedures.

[0027] Valvular diseases, such as valvular stenosis, are treated with procedures such as balloon dilation or percutaneous aortic valve implantation.

[0028] Cardiac arrhythmias: such as radiofrequency ablation surgery used to treat tachyarrhythmias.

[0029] II. Surgical Procedure:

[0030] Surgery typically involves inserting catheters, guidewires, or other instruments into the heart or blood vessels using vascular puncture techniques for diagnosis or treatment.

[0031] III. Characteristics of patients undergoing interventional surgery:

[0032] It is prone to bleeding and difficult to stop bleeding after surgery.

[0033] IV. Postoperative precautions:

[0034] Observe the puncture site for bleeding or hematoma.

[0035] Pay attention to the patient's electrocardiogram, symptoms, urine, etc., to rule out complications.

[0036] Patients are encouraged to drink plenty of water to promote the excretion of contrast agents and reduce the burden on the kidneys.

[0037] Advantages and disadvantages of interventional cardiac therapy

[0038] advantage

[0039] Minimal trauma: Cardiac interventional surgery usually does not require open-chest surgery, but only blood vessel puncture, so it is minimally invasive and recovery is fast.

[0040] Precision treatment: Doctors can reach the heart directly through blood vessels to perform precise diagnosis and treatment, improving surgical outcomes.

[0041] Reduced complications: Compared with traditional surgery, interventional cardiac treatment has fewer complications, such as a reduced risk of bleeding and infection.

[0042] Improving quality of life: For patients with coronary heart disease, interventional therapy can immediately improve blood supply to the heart, save blood vessels, and improve their quality of life.

[0043] shortcoming

[0044] Contrast agent allergy risk: Some patients are allergic to contrast agents, which may cause symptoms such as skin itching and difficulty breathing.

[0045] Vascular injury: When catheters and other instruments pass through blood vessels, they may damage the vessel walls, leading to complications such as bleeding and thrombosis.

[0046] Unable to completely remove lesions: For some complex cases, interventional treatment may not be able to completely solve the problem and needs to be combined with other treatment methods.

[0047] High skill requirements: Interventional therapy requires doctors to have a high level of technical expertise and rich experience. Operational errors may lead to complications.

[0048] Peripheral vascular surgery is the main approach for interventional procedures. Among them, the femoral artery and femoral vein are frequently chosen surgical vessels for coronary intervention. Due to the complex local anatomy and proximity to the groin area, the incidence of bleeding and infection is high when puncturing the femoral artery and femoral vein. Therefore, hemostasis is usually required at the wound site. After the procedure, sandbags are usually applied for pressure bandaging, and the patient needs to lie flat for 24 hours for immobilization. During this period, the sandbag may shift, reducing the effectiveness of pressure hemostasis, or prolonged fixation with tape may cause skin allergies, itching, and other discomforts for the patient.

[0049] The primary function of the bandage-assisted fixation device after cardiac interventional treatment is to compress the surgical site and help stop bleeding. Through physical compression, the risk of postoperative bleeding can be reduced, and the stability of the surgical site can be ensured.

[0050] Post-cardiac interventional procedure bandage fixation devices effectively secure the bandage, preventing slippage and curling, reducing patient pain, protecting the surgical site, and promoting wound healing. They are crucial for ensuring surgical success and patient recovery. However, some problems often arise during the actual use of post-cardiac interventional procedure bandage fixation devices. Below are some common problems and their causes: 1. Insecure bandage fixation: This may be due to poor bandage material, improper fixation methods, or excessive patient activity leading to bandage loosening. 2. Patient discomfort or pain: This may be due to an overly tight bandage compressing the skin and tissues, causing discomfort or pain; non-breathable material may also lead to skin dampness and discomfort. 3. Bleeding or hematoma: This may be due to improper bandage fixation at the surgical site, potentially leading to bleeding or hematoma formation. 4. Occluder dislodgement or displacement: This may be due to excessive post-operative activity, inappropriate occluder selection, or poor defect margin conditions, which may cause the occluder to dislodge or displace. 5. Risk of infection: The main reason may be that if the bandage fixation device is not kept clean and dry, or if the patient does not strictly follow the doctor's advice to take preventive measures against infection, infection may occur.

[0051] Currently, various types of postoperative bandage fixation devices for cardiac interventional procedures are available on the market. These devices aim to improve the stability of bandage fixation and patient comfort, effectively prevent postoperative bleeding, reduce pain, and promote patient recovery. Below is a detailed introduction to several common postoperative bandage fixation devices for cardiac interventional procedures: 1. Chest strap or chest fixation plate: This type of device strengthens support and protection at the incision site after thoracic surgery by fixing the patient's chest in a specific position, preventing wound dehiscence and reducing pain. 2. External sternal fixation splint: Specifically designed for external fixation of the thoracic cavity, protecting the wound site, relieving pain, and aiding in the treatment and rehabilitation of rib injuries and after open-chest surgery. 3. Ear root brace: Composed of three aluminum ear root braces and non-rigid straps, it is used for external fixation of the cervical spine structure and can be adjusted according to the patient's body shape to provide stable support.

[0052] Although various types of post-cardiac interventional treatment bandage fixation devices are currently available on the market, some problems still exist. For example, the bandage fixation devices mentioned above have the following issues: 1. Fixation stability: Some devices may loosen or shift during patient movement due to material or design issues, affecting the fixation effect. 2. Comfort: Some devices may cause discomfort or pain to patients due to overly rigid materials or unreasonable design. 3. Infection risk: If the device material is not breathable or improper cleaning, the risk of infection may increase. 4. Ease of use: Some devices are complex to operate, requiring professional assistance for wearing and adjustment, increasing the difficulty of use.

[0053] Please see Figures 1-6 This utility model provides an embodiment of a bandage-assisted fixation device after cardiac interventional therapy, comprising an auxiliary fixation compression bag 1, a first adjustable fixation bandage 2, a second adjustable fixation bandage 3, a third adjustable fixation bandage 4, a fourth adjustable fixation bandage 5, a conical sandbag 6, an anti-allergy regional adhesive tape 10, and a zipper 14. The auxiliary fixation compression bag 1 contains a conical sandbag 6 for applying pressure to the patient's wound to stop bleeding. The upper side of the auxiliary fixation compression bag 1 is provided with a zipper 14 for opening and closing, allowing the conical sandbag 6 to be removed. The four corners of the auxiliary fixation compression bag 1 are respectively fixedly fitted with first adjustable bandages for securing the auxiliary fixation compression bag 1. The system includes a fixed bandage 2, a second adjustable fixed bandage 3, a third adjustable fixed bandage 4, and a fourth adjustable fixed bandage 5. The first adjustable fixed bandage 2 and the third adjustable fixed bandage 4 are detachably connected to each other to fix the auxiliary fixed compression bag 1. The second adjustable fixed bandage 3 and the fourth adjustable fixed bandage 5 are detachably connected to each other to fix the auxiliary fixed compression bag 1. The lower ends of the first adjustable fixed bandage 2, the second adjustable fixed bandage 3, the third adjustable fixed bandage 4, and the fourth adjustable fixed bandage 5 are all detachably fitted with anti-allergy regional adhesive tape 10 to protect the patient's skin and improve the patient's comfort.

[0054] Please see Figures 1-2 In this embodiment, the upper ends of the first adjustable fixation bandage 2 and the fourth adjustable fixation bandage 5 are both fitted with first Velcro 7, and the lower ends of the second adjustable fixation bandage 3 and the third adjustable fixation bandage 4 are both fitted with second Velcro 8. The first adjustable fixation bandage 2, the third adjustable fixation bandage 4, the fourth adjustable fixation bandage 5, and the second adjustable fixation bandage 3 are all detachably connected to each other by the first Velcro 7 and the second Velcro 8. The length of the bandage can be adjusted by connecting the first Velcro 7 and the second Velcro 8 at different positions to adapt to different patients and different fixation needs.

[0055] Please see Figures 5-6In this embodiment, the lower ends of the first adjustable fixation bandage 2, the second adjustable fixation bandage 3, the third adjustable fixation bandage 4, and the fourth adjustable fixation bandage 5, near the auxiliary fixation compression bag 1, are all fitted with a third Velcro 9 for detachable connection with the anti-allergy regional adhesive tape 10. The upper end of the anti-allergy regional adhesive tape 10 is fitted with an adhesive structure corresponding to the third Velcro 9. Multiple sets of silicone blocks 11 for protecting the patient's skin and increasing comfort are evenly distributed and fixed from left to right on the end of the anti-allergy regional adhesive tape 10 near the patient's skin. The silicone blocks 11 have first vent holes 12 for increasing breathability evenly distributed on the side surface close to the patient's skin. Second vent holes 13 corresponding to the first vent holes 12 are evenly distributed on the side of the silicone blocks 11. The first vent holes 12 and the second vent holes 13 are interconnected.

[0056] When carrying out the work, first prepare the relevant structures of the device and place them in the corresponding positions;

[0057] Then open the zipper 14 on the auxiliary fixing compression bag 1, put the conical sandbag 6 into the auxiliary fixing compression bag 1 and zip up the zipper 14;

[0058] Next, place the auxiliary fixation compression bag 1 onto the patient's skin and then attach the anti-allergy regional adhesive tape 10 to the lower ends of the first adjustable fixation bandage 2, the second adjustable fixation bandage 3, the third adjustable fixation bandage 4, and the fourth adjustable fixation bandage 5 in sequence.

[0059] Then, the auxiliary fixation compression bag 1 is fixed with the first adjustable fixation bandage 2, the second adjustable fixation bandage 3, the third adjustable fixation bandage 4 and the fourth adjustable fixation bandage 5. According to the actual situation of the patient's wound and the location of the wound, the first Velcro 7 on the first adjustable fixation bandage 2 and the second Velcro 8 on the third adjustable fixation bandage 4 are attached to each other, and the first Velcro 7 on the fourth adjustable fixation bandage 5 and the second Velcro 8 on the second adjustable fixation bandage 3 are attached to each other.

[0060] And ensure that the silicone block 11 on the anti-allergy regional adhesive tape 10 fits the patient's skin, reducing the contact area between the bandage and the skin, and increasing breathability through the first vent 12 and the second vent 13 during the compression hemostasis process.

[0061] If bleeding is observed after 6 hours of compression, the conical sandbag 6 can be reapplied to the affected area to stop the bleeding by adjusting its position and angle.

[0062] Through the above steps, by setting up an auxiliary fixation compression bag 1 to hold the conical sandbag 6, and by setting up a first adjustable fixation bandage 2, a second adjustable fixation bandage 3, a third adjustable fixation bandage 4, and a fourth adjustable fixation bandage 5 to fix the auxiliary fixation compression bag 1 in coordination, it is possible to prevent the conical sandbag 6 from sliding or shifting during the compression of the patient's wound. The patient does not need to lie flat all the time. By setting an anti-allergy regional adhesive tape 10 at the end of the adjustable fixation bandage that contacts the patient's skin, the patient's skin can be protected, increasing their comfort. Not only is the hemostasis efficiency higher, but the comfort is also better. The conical sandbag 6 itself is an independently set structure. If bleeding is found after 6 hours of compression, it can still be used locally again for compression hemostasis, which greatly improves the efficiency of compression hemostasis. This solves the problem that the existing bandage auxiliary fixation devices after cardiac interventional treatment usually use sandbags for auxiliary pressure bandaging, and then the patient needs to lie flat for 24 hours for immobilization. During this period, the sandbag may shift, reducing the effect of compression hemostasis, or the long-term tape fixation may cause the patient's skin allergies, itching, and other discomforts.
