Abstract
A fluid drain for wounds includes a tube having one end insertable under the patient's skin into the wound, with the opposite end of the tube extending externally of the patient's skin; and a valve assembly at the opposite end of the tube. The valve assembly includes a first port for connection to a vacuum source, a second port connected to the opposite end of the tube, a third port for outletting the drained fluid into a container, a first one-way valve permitting the fluid to flow freely therethrough only from the second port to the first port, and a second one-way valve permitting the fluid to flow freely therethrough only from the first port to the third port.
Claims20
A fluid drain for wounds, comprising:
- a tube having a subcutaneous tubelet at one end insertable under the patient's skin into the wound, with the opposite end of the tube extending externally of the patient's skin;
- an anchoring member for anchoring said one end of the tube to the patient's skin;
- and a valve assembly at the opposite end of the tube;
- said valve assembly comprising:
- a first port for connection to a vacuum source;
- a second port connected to said opposite end of the tube;
- a third port for outletting the drained fluid into a container;
- a first one-way valve permitting the fluid to flow freely therethrough only from said second port to said first port;
- and a second one-way valve permitting the fluid to flow freely therethrough only from said first port to said third port.

- a first one-way valve permitting the fluid to flow freely therethrough only from said second port to said first port;
- and a second one-way valve permitting the fluid to flow freely therethrough only from said first port to said third port;
- and an anchoring member applied to an external part of the tube for anchoring the tube to the patient's skin, said anchoring member being of soft, resilient material and having an opening therethrough for receiving the tube, said opening being of generally elliptical cross-section having a length along its minor axis smaller than the outer diameter of the tube so as to firmly grip the tube, and a length along its major axis larger than the outer diameter of the tube, such that squeezing the anchoring member along its major axis releases the tube and thereby enables the anchoring member to be moved to any desired location along its length.
