Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an intelligent compression hemostasis device after thyroid surgery. Background Art

[0002] The thyroid gland is located in the front of the human neck and is surrounded by abundant blood vessels and nerves. Thyroid surgeries, such as thyroidectomy and partial thyroidectomy, will inevitably cause damage to the thyroid tissue and the blood vessels around it during the operation, resulting in a higher risk of postoperative bleeding. Postoperative bleeding is one of the common complications of thyroid surgery. If not treated in time, blood may accumulate in the neck to form a hematoma. Hematomas will not only compress the surrounding trachea, esophagus and nerves, causing patients to experience symptoms such as difficulty breathing, difficulty swallowing, and hoarseness, but in severe cases may even be life-threatening. Therefore, effective compression hemostasis after surgery is crucial to preventing hematoma formation and ensuring patient safety.

[0003] Traditional methods for stopping bleeding after thyroid surgery rely primarily on gauze packing and bandages. However, this method has several significant limitations: Uneven pressure: Gauze packing is difficult to precisely control, and pressure can vary across different areas, resulting in poor hemostasis in some areas, while excessive pressure in others can cause tissue damage. Real-time monitoring is impossible: Medical staff lack real-time visibility into bleeding and pressure levels at the compression site, making it difficult to adjust compression intensity in a timely manner.

[0004] Through the above analysis, the problems and defects of the existing technology are as follows:

[0005] (1) Uneven pressure: It is difficult to precisely control the pressure of gauze packing, and the pressure in different parts may be inconsistent, resulting in poor hemostasis in some areas, while excessive pressure in some areas may cause tissue damage.

[0006] (2) Unable to monitor in real time: Medical staff cannot understand the bleeding situation and pressure level of the compression site in real time, making it difficult to adjust the compression intensity in time. Summary of the Invention
