Abstract
The invention is directed to a lavage tip for use with a lavage system to irrigate living tissue. A fluid tip includes a fluid port and a suction or vacuum port, with the fluid port and vacuum port defining a cross-sectional area. A shield is connected to the fluid tip which has an open end with a surface area which is substantially larger than the cross-sectional area of the fluid tip. The open end of the shield is configured for placement against the tissue to be irrigated. The shield includes an articulating joint allowing relative angular movement between the shield and the fluid tip, whereby substantially all of the tissue to be irrigated at the open end of the shield may be irrigated without repositioning the open end relative to the tissue. The fluid tip may include an oxygen port for providing oxygen therapy to the tissue.
Claims7
A lavage tip for use with an epidermal lavage system to irrigate living tissue, said lavage tip comprising:
- a fluid tip including a fluid port, a suction port and an oxygen port;
- and
- a shield connected to said fluid tip, said shield having an open end configured for placement against the tissue to be irrigated, and wherein said shield defines an enlarged internal chamber which is disposed in fluid communication with each of said fluid port, said suction port and said oxygen port, and wherein said fluid port is configured for transporting an irrigating fluid to the chamber, said oxygen port is configured for transporting oxygen to the chamber to provide oxygen therapy to the tissue to promote faster healing, and said suction port is configured for transporting fluid from the chamber.
The lavage tip of claim 10, further comprising a neck attached to said shield and interconnecting said fluid tip with said shield, said articulating joint being disposed at a juncture between said neck and said shield.
A method of providing epidermal lavage for irrigation of external skin conditions comprising the steps of:
- a) providing a lavage tip comprising a fluid port, a suction port, and an oxygen port;
- b) providing a shield connected to said fluid tip, said shield having an open end configured for placement against a skin surface, and wherein said shield defines an enlarged internal chamber which is disposed in fluid communication with each of said fluid port, said suction port, and said oxygen port;
- c) applying fluid to said skin surface through said chamber;
- and
- d) applying oxygen to said skin surface under said enlarged chamber of said shield to help promote faster healing of said external skin condition;
- and
- e) providing suction to transport fluid from the chamber.
