Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a tip cap for preventing splashing of water from a medical debridement water jet. Background Technology

[0002] Medical water jet debridement is a new type of wound cleaning technology that uses water as a medium. Through a matching pressurization device, the originally low-pressure medical distilled water or saline is pressurized to the required high-pressure state, and then sprayed out through the nozzle of the medical water jet head. At this time, the nozzle sprays out a fine high-pressure water stream, which can cut and clean necrotic tissue and foreign objects in the wound, thereby achieving the purpose of debridement.

[0003] like Figure 1 , Figure 2 As shown, existing wound cleaning water jet heads all spray high-pressure water through the nozzle at the front end of the water jet head, forming a high-pressure water jet to cut the wound. At the same time, the Venturi effect generated by the high-pressure water jet carries away the waste generated during the cutting process and flushes it into the recycling pipe. Because of the cutting requirements, the water line is unobstructed in the horizontal direction.

[0004] Because of the complexity of wound surfaces and the varying hardness of different foreign objects or tissues requiring removal, and to ensure the most precise removal of foreign objects and necrotic tissue, the operator needs to estimate the required pressure based on experience, adjust the equipment to the appropriate pressure setting, and then begin debridement. Due to operator inexperience and the varying hardness of wounds, situations may arise where the blade cannot cut through, causing water to splash from both sides of the water jet head, contaminating the operating environment and the operator. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a tip cap that prevents water from splashing from medical debridement water jets, thus solving the problem of water splashing from medical debridement water jets.
