Abstract
An endotracheal tube (ETT) system and methods are provided. In at least one example, an ETT system may comprise, a tube, inflatable cuff coupled to the tube, and a restrictor. In at least one example the restrictor may comprise one more cavities. In a further example, a restrictor drainage assembly may be coupled to the restrictor, the restrictor drainage assembly configured to drain secretions that may be collected at a collection point formed by the restrictor when the ETT system is positioned in an airway of a patient and in an inflated state.
Claims15
An endotracheal tube (ETT) system, comprising:
- a tube;
- an inflatable cuff coupled to the tube;
- and
- a restrictor comprising one or more cavities, the restrictor surrounding the tube, wherein the inflatable cuff is positioned between the restrictor and the tube, and wherein the restrictor restricts the inflatable cuff to form a valley positioned between two protruding regions of the inflatable cuff upon inflation of the inflatable cuff.
An endotracheal tube (ETT) system, comprising:
- a tube;
- an inflatable cuff surrounding the tube;
- a restrictor surrounding an exterior surface of the inflatable cuff;
- and
- a restrictor drainage assembly coupled to the restrictor,
- wherein the restrictor is a band,
- wherein each of one or more openings included in the band open into an interior space of the band and wherein, when the inflatable cuff is in an inflated state,
- a diameter of a first protruding region of the inflatable cuff that is upstream of the restrictor is greater than a diameter of the restrictor, and
- a diameter of a second protruding region of the inflatable cuff that is downstream of the restrictor is greater than the diameter of the restrictor.
An endotracheal tube (ETT) system, comprising:
- a first tube;
- an inflatable cuff surrounding the first tube;
- a restrictor surrounding an exterior surface of the inflatable cuff comprising one or more cavities;
- and
- a restrictor drainage assembly coupled to the restrictor, the restrictor drainage assembly comprising a restrictor drainage bulb,
- wherein the inflatable cuff is positioned between the restrictor and the first tube, and wherein the restrictor restricts the inflatable cuff to form a valley positioned between two protruding regions of the inflatable cuff upon inflation of the inflatable cuff.
