The present invention relates to a fluid drain tube associated with a device for connecting the tube to the user of the tube, and more particularly to a cerebrospinal fluid (“CSF”) drain tube with a clip that signals the patient when the tube is being pulled.
It is common for patients with tubes or catheters inserted into their skull or other body portion (e.g., a vein) for fluid drainage or the like to pull out the tube or move about in a way that causes the tube to begin to move out of the skull/body portion. U.S. Pat. Nos. 4,707,906, 6,247,211 and 3,990,454 are all incorporated by reference in their entireties.
In accordance with a first aspect of the present invention there is provided a device for signaling the imminent removal of a tube from an opening in a patient's skin. The device includes a tube attachment mechanism that is configured to be temporarily secured to a tube, a tether having a proximal end and a distal end, and a patient attachment mechanism attached to the distal end of the tether. The proximal end of the tether is secured to the tube attachment mechanism. In a preferred embodiment, the patient attachment mechanism is a clip that is configured to be clipped to a patient's hair. In another preferred embodiment, the patient attachment mechanism is an adhesive patch configured to be adhered to a patient's skin. In another preferred embodiment, the device includes a plurality of tethers each having a proximal end and a distal end, with the proximal end of each tether being secured to the tube attachment mechanism, and a patient attachment mechanism attached to the distal end of each of the tethers. In an embodiment, each of the patient attachment mechanisms is a clip that is configured to be clipped to a patient's hair. In another embodiment, each of the patient attachment mechanisms is an adhesive patch configured to be adhered to a patient's skin.
In a preferred embodiment, the device includes a tube and the tube attachment mechanism is permanently attached to the tube. In another embodiment, the tube and the device are provided in a kit.
In accordance with another aspect of the present invention there is provided a method that includes the steps of obtaining a tube and obtaining a device for signaling the imminent removal of the tube from an opening in a patient's skin. The device includes a tube attachment mechanism, a tether having a proximal end secured to the tube attachment mechanism and a distal end, and a patient attachment mechanism attached to the distal end of the tether. The method further includes the steps of securing the tube attachment mechanism to the tube, forming an opening in a patient's skin, inserting the tube into the opening, and securing the patient attachment mechanism to the patient. The steps can be performed in any order. For example, the tube attachment mechanism can be secured to the tube before or after the tube is inserted into the opening in the patient's skin. Also, the patient attachment mechanism can be secured to the patient before or after insertion of the tube.
In a preferred embodiment, the patient attachment mechanism is secured to hair on the patient's head. In another preferred embodiment, the patient attachment mechanism is secured to the patient's skin. In an embodiment, the device includes a plurality of tethers each having a proximal end and a distal end. The proximal end of each tether is secured to the tube attachment mechanism, and a patient attachment mechanism is attached to the distal end of each of the tethers. The method further includes the step of securing each of the patient attachment mechanisms to the patient. In a preferred embodiment, the tube is inserted into an opening in the patient's skin and an opening in the patient's skull.
