Description

Technical Field

[0001] The utility model relates to the technical field of tracheal cannula, in particular to an inner cannula of a tracheotomy cannula and a tracheotomy cannula. Background Art

[0002] The tracheotomy tube is an important instrument for treating respiratory diseases. The structure of the traditional tracheotomy tube can be seen in the Chinese utility model patent with the authorization announcement number CN213131408U, which discloses an inner tube for tracheal intubation and a tube assembly containing the inner tube. The tube assembly includes an inner tube and an outer tube. The tail end of the outer tube is provided with a fixing plate, and the fixing plate is provided with a through hole for a lace. The fixing belt passes through the through hole to fix the outer tube on the patient's neck. The inner tube is inserted into the outer tube. The head end of the inner tube is provided with an air bag for closing the airway. The air bag is connected to an airway. The outer end of the airway is provided with an inflatable piston. The inflatable piston constitutes an inflating mechanism. Inflating the air bag can achieve the closure of the airway and the fixation of the inner tube. After the air bag is exhausted, the inner tube can be pulled out. The tail end of the inner tube is provided with a universal connector for docking with a simple respirator or a ventilator pipeline. The universal connector constitutes a ventilator connector, and the ventilator connector is fixed integrally with the tube body of the inner tube.

[0003] When the patient's condition improves, there will be a period of time when the patient is disconnected from the ventilator, so that the ventilator connector of the tracheotomy tube is disconnected from the ventilator to perform oral and nasal breathing training on the patient. The tracheotomy tube is still left on the patient's body, and the ventilator connector of the tracheotomy tube needs to be blocked. Generally, gauze is used to cover it, and the gauze is bonded and fixed using the patient's neck. However, since the ventilator connector protrudes from the fixing plate of the outer tube and the protrusion is relatively high, it is not conducive to the smooth attachment of the gauze, which causes inconvenience to the covering operation. In addition, the ventilator connector protruding from the patient's neck will also affect the patient's dressing and neck movements, making it inconvenient for nursing operations.

When the tracheotomy tube does not need to be connected to the ventilator, the ventilator connector can be separated from the inner tube main body, and removing the ventilator connector can avoid the ventilator connector being left at the patient's neck and occupying too much height, and only the inner tube main body is left in the outer tube of the tracheotomy tube and forms a tracheotomy tube retention part, which is conducive to reducing the protruding height of the tracheotomy tube retention part, improving the flatness of the ventilating port of the tracheotomy tube retention part, facilitating the covering of gauze, facilitating the patient to wear clothes and move the neck, and facilitating the convenience of nursing operations.

[0033] Embodiment 1 of the tracheotomy cannula of the present invention:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the tracheotomy cannula includes an inner cannula and an outer cannula 1, the inner cannula includes an inner tube main body 2 and a ventilator connector 3, the inner tube main body 2 and the ventilator connector 3 are separately arranged, the inner tube main body 2 has an insertion end for inserting into the trachea and an exposed connection end, and the ventilator connector 3 is detachably connected to the connection end of the inner tube main body 2. The ventilator connector 3 is used to connect to the ventilator, the insertion end of the inner tube main body 2 is used to pass through the outer cannula 1 and be located in the patient's trachea, and the connection end of the inner tube main body 2 extends out of the outer cannula 1 to facilitate the connection of the ventilator connector 3.

[0035] When the tracheotomy tube does not need to be connected to a ventilator, the ventilator connector 3 can be separated from the inner tube main body 2. Removing the ventilator connector 3 can prevent the ventilator connector 3 from remaining at the patient's neck and occupying too much height. Only the inner tube main body 2 remains in the outer tube 1 and forms a tracheotomy tube retention part, which is beneficial to reducing the protruding height of the tracheotomy tube retention part. After the ventilator connector 3 is removed, the pipe opening of the connecting end of the inner tube main body 2 constitutes the vent of the tracheotomy tube retention part, which improves the flatness of the vent of the tracheotomy tube retention part, is convenient for covering with gauze, and is convenient for patients to wear clothes and move their necks, which is beneficial to the convenience of nursing operations.

When in use, the ventilator joint 3 is located above the inner tube main body 2, so that the end surfaces of the ventilator joint 3 and the inner tube main body 2 are fitted and docked and connected, which is conducive to making the height of the part of the inner tube main body 2 protruding from the outer sleeve 1 lower, making the ventilator port of the retained part of the tracheotomy sleeve smoother, and more conducive to nursing operation. The inner tube fixing plate 21 and the joint fixing plate 31 are provided with a connecting structure for connecting the inner tube main body 2 and the ventilator connector 3 together. The inner tube fixing plate 21 and the joint fixing plate 31 are used to facilitate the setting of the connecting structure and facilitate reliable connection. After the inner tube main body 2 and the ventilator connector 3 are connected together, air can be supplied through the ventilator.

[0037] The insertion end of the inner tube main body 2 is provided with an air bag 4 for sealing the patient's trachea, and the connecting end of the inner tube main body 2 is provided with an inflation mechanism 5 connected to the air bag 4.
