Abstract: A device for sealing a tracheostoma in a patient includes a seal member for insertion through the tracheostoma to a trachea. The seal member includes a disc having a predetermined line of weakness. In a first configuration, the seal member forms a seal by being pulled against the tracheostoma. In a second configuration, the seal member is removed from the trachea through the tracheostoma by breaking along the line of weakness.

Abstract: Provided is a spoiler, in particular adaptable spoiler, for a wind turbine blade including: a main body including an airfoil shaped surface to be exposed to air flow; at least one stiffening element distinct from the main body and supporting the airfoil surface, wherein the stiffening element is in particular configured to enforce the shape of the airfoil surface during loading by wind during operation of the wind turbine.

Abstract: A device for sealing a tracheostoma in a patient, comprising a seal member for insertion through the tracheostoma to the trachea, which in a first configuration can form a seal by being pulled against the tracheostoma, and which in a second configuration can be removed from the trachea through the tracheostoma. Preferably, the seal member comprises a disc having a predetermined line of weakness, and a first thread attached to the disc, wherein the disc can be broken along the predetermined line of weakness by pulling the thread. There is also disclosed a kit comprising the device and an external cover, a method of constructing the device, and a method of sealing a tracheostoma in a patient, comprising inserting the sealing member through the tracheostoma into the patient's trachea, and pulling the sealing member to form a seal against the tracheostoma.
