A tracheostomy system includes an outer multi-layered tube, which can be expanded or allowed to contract as necessary in order to receive various sizes of cannula tubes. A dilator is used to initially insert the outer tracheostomy tube into the tracheostoma. After the initial installation dilator is removed, various sizes of dilators having a cannula mounted about them can be inserted into the outer tracheostomy tube. The multilayered tube will then expand in response to insertion of the various sizes of dilator cannula assembly being placed. When the dilator is removed the cannula tube will remain in place to maintain the desired diameter tracheostomy tube. This provides a means in which the diameter of the tube can be changed without having to actually remove and reinsert a different tube.

A tracheostomy tube is proved. The tracheostomy tube includes an outer cannula that comprises an outer cannula connector comprising a first keying feature. The tracheostomy tube further comprises an inner cannula comprising an inner cannula connector including a second keying feature configured to complement the first keying feature when the inner cannula is inserted into the outer cannula. Further, a method is provided, whereby the method comprises inserting an outer cannula into a patient's trachea, and inserting an inner cannula into the outer cannula such that a keying feature on an inner cannula connector of the inner cannula engages a complementary keying feature on an outer cannula connector of the outer cannula.

An HME for a tracheostomy tube has a flexible outer housing of a gas-permeable material containing an HME element of discrete particles, granules or the like of a hygroscopic material. The particles are contained between the outer housing and an inner wall of a foam. The inner wall has a ciliated surface facing the end of the tube, which acts to distribute gas over the surface of the HME element. The HME is attached to a flange on an inner cannula by means of a removable adhesive. The HME may include a suction port through a self-closing aperture, which makes a wiping seal with a suction catheter inserted in the tube.

A tracheotomy apparatus including a cuff, a port and a sensor. The cuff defines a chamber and wraps around a portion of the subject's neck. A fluid delivery system delivers a gas to the chamber through the port as the subject naturally respires. The sensor monitors carbon dioxide in another gas exhaled from the subject as the subject naturally respires. The sensor can be coupled to a controller that monitors pre-selected parameters, and optionally activates an alarm when those parameters are unmet. A related method includes aligning the tracheotomy cuff with a subject's tracheotomy tube; delivering a first gas so that the subject can naturally respire, drawing the gas from the apparatus; and monitoring a second gas exhaled by the subject into the tracheotomy cuff. Optionally, an alarm is activated when the monitored parameters fall outside pre-selected parameters.

The invention belongs to the technical field of medical instruments and relates to a percutaneous dilatational tracheostomy (PDT) tube instrument set capable of reducing cross infection. The instrument set comprises a puncture needle, an injector, a guide wire, a guide wire fixator, a dilator, a tracheostomy tube, a tube catheter and an isolation hood. The PDT tube instrument set constructs a local isolation space at an operation part of a patient and locks an infection source to reduce the required protection grade so as to reduce the burden of medical staff in personal protection, and aims to provide daily available effective protection while serving as an operation tool of tracheostomy tube operation. In addition, the dilator is of an expandable/contractible net cage type structure, canbe easily inserted into a puncture stoma in a small diameter state and can expand in a large diameter state, so that expansion of the trachea and pretracheal tissue of the patient can be completed through one step. Compared with an existing PDT tube instrument requiring multi-step expansion, the PDT tube instrument set can reduce the number of required instruments and the operation steps and shorten the operation time.

The invention discloses an automatic sputum suction system capable of preventing tracheal cannulas from leaking liquid and a sputum suction method thereof, which belong to the technical field of trachea cannulas.
