Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a tracheotomy cannula.
Background
Tracheotomy is a common operation for relieving dyspnea caused by laryngeal dyspnea, respiratory dysfunction or retention of lower respiratory tract secretion, and can keep the respiratory tract of a patient smooth, improve dyspnea caused by various reasons, correct the anoxic state of the patient, and the like. The tracheotomy cannula is an artificial airway used after tracheotomy of a patient, is widely used clinically, and has the following defects in the clinical application process:
1. After tracheostomy tubes, it is often necessary to place oxygen and/or humidification conduits within the tracheostomy tube to assist the patient in respiratory and airway humidification. When oxygen or humidifying liquid is input to a patient, the oxygen pipeline or the humidifying pipeline is mostly inserted into the tracheostomy tube from the upper end opening of the tracheostomy tube, and then the oxygen pipeline or the humidifying pipeline is wound and fixed on the outer wall of the upper end opening of the tracheostomy tube or other exposed parts of the tracheostomy tube by using a medical adhesive tape so as to ensure continuous supply of the oxygen and the humidifying liquid and prevent blockage of the respiratory tract caused by dry sputum. If the medical adhesive tape is firmly fixed, the medical adhesive tape is required to be torn off when the oxygen pipeline or the humidifying pipeline is replaced every time, and the tracheotomy intubation is extremely easy to twist to stimulate a patient to cause cough and even take off the tube in the adhesive tape tearing process. The method not only makes the patient feel uncomfortable, but also brings inconvenience to life and medical care, and threatens the life safety of the patient when serious.
2. The current blocking balloon is cylindrical. After filling, the balloon can press the inner wall of the trachea of the longer section, so that the mucous membrane of the longer section of the inner wall of the trachea is pressed. In addition, the balloon with the shape has more folds in the contracted state, which affects the insertion of the tracheostomy tube.
3. It was found that ischemic injury of the tracheal mucosa occurred when the pressure between the cuff and tracheal wall exceeded the perfusion pressure of the tracheal mucosa capillaries (20-30 mmHg). The long-time over inflation of the cuff can also cause the tracheal mucosa pressed by the cuff to generate edema necrosis, ulcer formation and tracheal cartilage necrosis, fibrous tissue hyperplasia and/or tracheal collapse, thereby forming tracheal stenosis, and the injury caused by the airway stenosis is large and the treatment difficulty is high. The detection method of the cuff filling pressure comprises three methods (1) a finger touch method, namely, the finger touch indication air bag is similar to the nose tip in elasticity to indirectly judge the cuff filling pressure, and the method is most commonly adopted in the emergency tracheal intubation. This approach is highly subjective and often results in over inflation of the cuff. (2) The cuff pressure gauge detects the filling pressure of the cuff reliably and accurately. However, manual measurement does not effectively control the cuff pressure and can cause the cuff to leak when connecting and disconnecting the pressure tube. The cuff inflation pressure is thus often set to be somewhat higher than the target value using a cuff pressure gauge. (3) Automatic inflator continuous pressure measurement or continuous cuff pressure monitoring systems have great advantages in continuously monitoring cuff pressure and stabilizing cuff pressure, but are expensive and difficult to popularize in clinical practice.
4. The section from the subglottal to the tracheal cannula balloon generates more secretion, but is not easy to suck out to form a potential infection source.
