Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a negative pressure drainage device for chronic wound leakage. Background Technology

[0002] Chronic wound leakage not only causes immense suffering for patients but also severely hinders wound healing and increases the risk of infection, posing a significant challenge in clinical treatment. Traditional wound management methods, such as regular dressing changes, are ineffective in managing large amounts of exudate, and frequent procedures can easily lead to secondary trauma. Furthermore, they are inadequate in absorbing exudate and maintaining a moist wound environment. While ordinary drainage tubes can drain some fluid, they are inefficient for the complex exudate situations in chronic wounds, prone to clogging, and lack precise negative pressure control, failing to meet clinical needs. With advancements in medical technology, the demands for effective treatment and patient comfort in chronic wounds are increasing, making the development of a device that efficiently manages chronic wound leakage an urgent necessity. Negative pressure drainage technology has emerged in this context. By creating a negative pressure environment, it accelerates exudate drainage, promotes blood circulation in the wound, and facilitates healing. However, existing negative pressure drainage devices have shortcomings in terms of specificity for chronic wounds, portability, and ease of operation, requiring optimization and upgrading to better serve clinical needs and help patients with chronic wounds alleviate pain and accelerate recovery.

[0003] Based on the above, a negative pressure drainage device for chronic wound leakage is too rigid at the wound connection, has poor comfort, and is complicated to replace. If the wound needs to be replaced frequently, it is easy to cause secondary damage to the wound. Therefore, a quick replacement device is also essential. Utility Model Content
