Abstract
A wound drain removal device allows an implanted wound drain to be removed from a patient in a manner that limits the amount of tension that develops within the wound drain. The wound drain removal device includes a gripping surface and a handgrip for applying a pulling force to an outflow tube of the wound drain. The gripping surface is configured to slip relative to an outer surface of the outflow tube when a removal force associated with removal of the wound drain exceeds a predetermined threshold force.
Claims22
A device for use in removing an implanted wound drain from a patient, the device comprising:
- a handgrip for supplying a removal force to the wound drain outflow tube to remove the implanted wound drain from the patient;
- and
- a gripping surface carried by the handgrip and configured to grip and apply the removal force to an outer surface of the wound drain outflow tube and to slip relative to the outer surface when the removal force exceeds a predetermined threshold force.
A pinch grip for removing an implanted wound drain, the pinch grip comprising:
- a pair of opposing gripping surfaces that are movable relative to one another;
- an elastic joint;
- and
- a pair of opposing levers attached to the elastic joint for moving the opposing gripping surfaces relative to one another and applying a force to a wound drain outflow tube;
- wherein the pair of opposing gripping surfaces are configured to grip and apply pulling force to an outer surface of the wound drain outflow tube when the outflow tube has a tension less than a predetermined threshold tension and slip relative to the outflow tube when the tension exceeds the predetermined threshold tension.
A device for removing an implanted wound drain from a patient, the device comprising:
- one or more gripping surfaces for applying a pulling force to a wound drain outflow tube;
- and
- means for causing the one or more gripping surfaces to slip relative to the wound drain outflow tube when a removal force associated with removal of the wound drain from the patient exceeds a predetermined threshold.
A method for removing an implanted wound drain from a patient, the method comprising:
- squeezing an outer surface of a wound drain outflow tube with a removal device;
- and
- tensioning the outflow tube with the removal device to remove the implanted wound drain, wherein the removal device is configured to slip relative to the outer surface of the wound drain outflow tube when a removal force associated with removal of the wound drain from the patient reaches a predetermined threshold magnitude.
