The laryngeal mask part can be used alone. When the environment above the glottis of the patient is not good, the laryngeal mask cannot be perfected. To establish a breathing channel, the endotracheal tube can be inserted into the patient's trachea through the laryngeal mask, which can reduce the patient's discomfort and increase the probability of successful establishment of the breathing channel. damage caused.

Description

Detachable endotracheal tube laryngeal mask composite device

technical field

The utility model relates to the field of medical equipment, in particular to a detachable tracheal tube laryngeal mask composite device.

Background technique

Both endotracheal tube and laryngeal mask are necessary devices in general anesthesia. The endotracheal tube is a subglottic ventilation device. One end is connected to the ventilator, and the other end is inserted into the trachea through the mouth, throat, and glottis. After the cuff is inflated, it forms a closed loop with the ventilator to provide a mechanical ventilation circuit for the patient. The laryngeal mask is a supraglottic ventilation device. One end of the position is also connected to the ventilator, and the other end is placed in the hypopharynx cavity through the oral cavity. The esophagus and the hypopharynx cavity are closed with an air bag, and the artificial airway is established by ventilation through the laryngeal cavity.

The above two ventilation devices have their own advantages and disadvantages. The tracheal tube is often used for patients under general anesthesia, muscle relaxation and mechanical ventilation because of its precise positioning and airtightness. Coughing, discomfort, and sympathetic nerve stimulation induce circulatory instability and even laryngospasm. Improper treatment may threaten the patient's life. The laryngeal mask is easy to use, has a high success rate of placement, and can quickly establish an artificial airway. However, the traditional laryngeal mask may have incomplete sealing with the respiratory tract, increased oral secretions, and is easy to shift. It cannot effectively isolate the respiratory tract from the digestive tract. Can cause flatulence, severe regurgitation or aspiration.

Contents of the invention

The technical problem to be solved by the utility model is to provide a detachable tracheal tube laryngeal mask composite device, which can meet different glottic environments and patients of different heights. When the glottic environment of the patient is better, a single A single laryngeal mask device is enough. When the patient's glottis environment is not good, the endotracheal tube can be used to enter the trachea through the through hole on the laryngeal mask, and the endotracheal tube can be fixed on the laryngeal mask tube with a joint device. At the same time, the endotracheal tube can be adjusted The length retracted into the inside of the joint device is used to control the length of the endotracheal tube going deep into the patient's trachea, which can meet the needs of different patients.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The detachable endotracheal tube laryngeal mask composite device is characterized in that it includes a laryngeal mask tube, a laryngeal mask is installed and fixed at one end of the laryngeal mask tube, and the laryngeal mask is a hollow elastic bag structure inside, and the central position is open There is a laryngeal mask through hole, one end of the laryngeal mask through hole is sealed and fixedly connected with one end of the laryngeal mask catheter, and the side of the laryngeal mask is connected to the laryngeal mask inflation tube inflated inside the laryngeal mask sac structure through the connection port. The other end of the laryngeal mask catheter is equipped with a laryngeal mask joint, and the laryngeal mask joint is detachably and hermetically connected to the joint device through a sealing structure. The joint device is a hollow pipe with one end sealed, and the joint The other end of the device is equipped with a detachable sealing buckle, and one end of the joint device equipped with a detachable sealing buckle is detachably sealed and fixed with a tracheal tube, and one end of the tracheal tube is connected to the connector through the detachable sealing buckle The device is detachably connected, the other end of the endotracheal tube is the outer port of the endotracheal tube, the outer port of the endotracheal tube passes through the inside of the laryngeal mask tube and protrudes through the through hole of the laryngeal mask, the side wall of the joint device A tracheal tube valve is installed.

In order to optimize the above-mentioned utility models, the specific measures taken also include:

The connecting port is installed on the outer surface of the laryngeal mask, and the inflatable tube of the laryngeal mask is located outside the laryngeal mask conduit.

The connecting port is installed on the inner surface of the through hole of the laryngeal mask, the laryngeal mask air tube is located inside the laryngeal mask duct, and the outer end of the laryngeal mask air tube protrudes outward through the tube wall of the laryngeal mask duct.

A laryngeal mask inflation valve is installed at the outer end of the laryngeal mask inflation tube.

The inner wall of the laryngeal mask joint is processed with internal threads, the outer surface of the sealing device is processed with external threads, and the laryngeal mask joint and the sealing device are detachably and sealed connected through a sealing thread group.

The detachable sealing buckle is composed of two semi-annular metal buckles. A semi-annular rubber pad is installed on the inner side of the semi-annular metal buckle. One end of the two metal buckles is connected by a rotatable hinge. The other ends of the two metal buckles mentioned above are detachably connected by buckles.

The capsule structure of the laryngeal mask is made of elastic rubber.

The sealing end of the joint device is sealed by a detachable sealing cover.

The outer port of the catheter is a round port.

When this detachable tracheal tube laryngeal mask composite device is used, the laryngeal mask and tracheal tube can be disassembled, the laryngeal mask is placed above the patient's glottis, and the laryngeal mask is inflated through the laryngeal mask inflation tube. At this time, the volume of the laryngeal mask increases. Large, closed esophagus and hypopharynx cavity, established artificial airway through laryngeal cavity ventilation. If the laryngeal mask can perfectly establish a breathing channel, it only needs to be connected to the ventilator through the threaded structure on the laryngeal mask connector.

If the laryngeal mask cannot perfectly establish the breathing channel due to the poor environment above the glottis of the patient, and the seal is incomplete, at this time, it is necessary to use the tracheal tube to extend into the patient's trachea to establish a breathing channel through the tracheal tube, and then pass the tracheal tube through The laryngeal mask tube and the through hole of the laryngeal mask extend into the patient's trachea. Since the laryngeal mask compresses and closes the esophagus and the hypopharynx cavity, the expansion of the tracheal opening reduces the discomfort caused by friction when the tracheal tube is inserted into the patient's trachea. The length of the trachea of each patient is different due to the difference in body size and age, and the length of the required endotracheal tube is also different. When the endotracheal tube is deep into the appropriate position, the remaining endotracheal tube can be inserted into the hollow tube of the joint device , and is sealed and fixed by a detachable sealing buckle, and finally the sealing device and the throat joint are sealed and connected through mutually compatible sealing threads. Since the other end of the joint device is in a sealed state, air can be inflated into the joint device through the endotracheal catheter valve Create a breathing channel. When the tracheal tube is removed with the laryngeal mask device, the hypoxic process will not occur during the replacement process. After the patient is awake and the laryngeal mask device is removed, the comfort level will be significantly improved, and the incidence of airway injuries such as coughing and hoarseness will be significantly reduced.

Since the other end of the joint device is a detachable sealing device, when a bronchoscope is needed for endoscopic inspection, the endotracheal tube can be removed and a bronchoscope can be inserted for endoscopic inspection.
