Description

Technical Field

[0001] The utility model relates to the technical field of tracheal sealing, and mainly relates to a progressive tracheal sealing device. Background Art

[0002] Currently, tracheotomy (abbreviated as tracheotomy) is a common method for rescuing critically ill patients. An incision approximately 3 cm long is made along the anterior midline of the neck from the lower edge of the patient's thyroid cartilage to near the suprasternal fossa. A tracheostomy tube suitable for the size of the incision is inserted to establish a channel connecting the trachea to external air or a breathing tube. The use of a tracheostomy tube can effectively clear sputum that is blocked or retained in the airway of critically ill patients. As a ventilation circuit, it can quickly relieve the patient's symptoms of hypoxia and respiratory distress. As the patient's condition recovers, a trial tube sealing operation is often performed clinically to assess the patient's cardiopulmonary function reserve and determine whether the patient is suitable for extubation.

[0003] The prerequisite for performing tube sealing on patients with tracheotomy is that the patient has sufficient cardiopulmonary function reserve, and his or her own respiratory tract (mouth, nose, throat, and airway) is unobstructed, and the patient can adapt to the change in ventilation status after extubation; in clinical practice, the tracheostomy tube is gradually blocked, starting from blocking 1 / 2 and 2 / 3 of the tracheostomy tube cross-sectional area to complete blockage, with the aim of dynamically evaluating the patient's cardiopulmonary function and ventilation adaptability. Compared with complete tube blocking, progressive tube sealing has better extubation success rate, safety, and patient tolerance.

[0004] However, there are currently no sealing devices compatible with all tracheostomy tube models on the market. Clinically, medical staff often use homemade tube-sealing devices, such as cotton swabs, which are wrapped with gauze until the swab matches the inner diameter of the tracheostomy tube. This seals the tube, but is inconvenient to operate and increases the risk of infection. Alternatively, soft rubber can be used, but due to the difficulty of creating the appropriate inner diameter and the inconvenience of obtaining the material, it can only be used for complete tube sealing and has a relatively limited function.
