Description

Tracheotomy sleeve pressure detection device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a tracheostomy tube pressure detection device.

Background

Tracheotomy refers to cutting the cervical trachea, and placing the tracheotomy tube into the tracheotomy tube sleeve, and is a common operation for relieving dyspnea caused by laryngeal dyspnea, respiratory dysfunction or lower respiratory tract secretion retention. A tracheotomy tube, which is called as trachea cannula for short, is a medical instrument for creating a temporary artificial respiratory passage for patients, especially patients incapable of spontaneously breathing.

When mechanical ventilation is carried out or the aspiration asphyxia is prevented and treated through the tracheotomy tube, the pressure range of the air sac of the tracheotomy tube is strictly required. Too high pressure may stress the airway mucosa to cause damage, too low pressure may cause air leakage or cause aspiration asphyxia, or even pulmonary infection, affecting the prognosis of the patient. Therefore, the tracheostomy tube needs to stabilize the balloon pressure, but chronic leakage is common to balloons inflated for long periods of time. The existing tracheotomy tube either does not have a pressure monitoring function or is complex in structure, and a simple and effective monitoring means is lacked to ensure safe operation of the tracheotomy tube.
