In arteriovenous puncture procedures such as cardiovascular intervention, coronary angiography, and hemodialysis, hemostasis at the puncture site is a critical aspect of postoperative care. Traditional manual compression is not only time-consuming and labor-intensive, but also difficult to maintain consistent pressure. This can easily lead to under- or over-compression due to fatigue or inexperience. To address this clinical challenge, the radial artery compresses the hemostat was developed. Through its user-friendly structural design, precise pressure control, and integrated practical functions, modern hemostatic forceps achieve scientific and controllable pressure hemostasis, effectively avoiding the drawbacks of traditional methods and significantly improving postoperative safety and care efficiency.1. User-Friendly Structure: Anatomically Conforms to Ensure Blood Flow and Stable FixationPrecise compression requires a precise fit between the device and the human anatomy. The high-quality radial artery compresses the hemostat, featuring a curved design that conforms to the physiologic curvature of the radial artery puncture site in the forearm. This ensures that the compression plate applies perpendicularly to the puncture site, achieving targeted compression. More importantly, its structural design fully considers the integrity of blood circulation in the hand—effectively compressing the radial artery while avoiding interference with the ulnar artery, ensuring unobstructed palmar collateral circulation and preventing ischemia, numbness, or pain in the hand caused by excessive compression. Furthermore, the ergonomically designed fixing strap, with its non-slip padding, ensures a secure fit on the patient's forearm, preventing slight movement and ensuring consistent and accurate pressure application.2. Precise Pressure Control: From "Judgment by Experience" to "Quantitative Operation"Traditional compression relies on subjective feel by medical personnel, while modern hemostat applications utilize a "precision scale" system that allows for visual and adjustable pressure. The core component is a rotating adjustment knob or cap, which gradually tightens the compression strap via a threaded mechanism. The screw cap features a clear pressure scale or compression cycle indicator, allowing healthcare professionals to set the appropriate compression level based on individual factors such as patient size, coagulation function, and puncture sheath diameter, referencing clinical guidelines. For example, initial compression can be set at the critical point for complete hemostasis, followed by gradual decompression within the first few hours after surgery, achieving "gradient deflation." This quantitative approach eliminates the uncertainty of relying on feel, preventing both subcutaneous hematomas caused by insufficient compression and vascular spasm or localized tissue necrosis caused by excessive compression, truly achieving personalized and precise hemostasis.3. Practical Function Integration: Improving Safety and User ExperienceIn addition to the core compression mechanism, the hemostat incorporates several practical features to further optimize its use. The elastic compression band, combined with a buffer spring, automatically adjusts tension with slight patient movement, absorbing shock and preventing sudden pressure fluctuations. The transparent compression plate is another key feature, allowing healthcare professionals to directly observe the skin color, bleeding, or swelling around the puncture site without removing the device, allowing for immediate detection of any abnormalities. The highly transparent material combined with a clear field of view significantly enhances the convenience and safety of postoperative monitoring. Furthermore, the lightweight material reduces the burden on patients, enhances comfort, and reduces discomfort caused by prolonged compression.4. Clinical Advantages: Shortened Time, Reduced Complications, and Accelerated RecoveryThe direct clinical benefit of precise compression is significantly improved hemostasis. Using hemostat forceps significantly shortens the time to effective hemostasis, reduces local fibrosis at the puncture site, and lowers the incidence of complications such as hematomas, pseudoaneurysms, and arteriovenous fistulas. Postoperative bed rest time is shortened, allowing patients to ambulate sooner. This not only improves comfort and quality of life, but also accelerates ward turnover and optimizes medical resource allocation.The radial artery compresses the hemostat, with its user-friendly design, precise adjustment, and integrated multi-functions, transforms postoperative hemostasis from a manual procedure reliant on experience into a scientific, controllable, and standardized process. This not only ensures patient safety and reduces the burden on medical staff, but also promotes the refinement and standardization of interventional medicine. In today's world where medical quality and patient experience are emphasized, this device, which combines safety, precision and practicality, has become an indispensable tool in modern catheterization laboratories and postoperative care.
