Description

Built-in tracheal catheter laryngeal mask combined ventilation device for general anesthesia

Technical Field

The invention relates to the technical field of medical instruments, in particular to a built-in tracheal catheter and laryngeal mask combined ventilation device for general anesthesia.

Background

The laryngeal mask is successfully developed and used in clinic in the middle of 80 years, and is introduced in 90 years in China. The application of the laryngeal mask is greatly developed at present, and the application range is wider and wider. The laryngeal mask is an effective means for establishing a safe airway in general anesthesia operation. When general anesthesia operation is performed, auxiliary respiration is needed to be performed on an operation patient so as to keep the general anesthesia hemodynamics of the patient stable, and common auxiliary respiratory ventilation devices comprise an endotracheal tube ventilation device and a laryngeal mask respiratory ventilation device. The tracheal tube ventilating device is composed of a tracheal tube formed by an elongated tube, and an inflatable balloon is arranged at the distal end of the elongated tube. During operation, the distal end of the tracheal tube is inserted into the patient's mouth and passes through the patient's laryngeal inlet (or glottic opening) and into the patient's trachea. Once so positioned, the tracheal tube is inflated to seal the interior passage of the trachea. After the seal is formed, a positive pressure is applied to the proximal end of the tracheal tube to inflate the patient's lungs. The tracheal catheter has the advantages that the tracheal catheter can bear large sealing pressure and is not easy to leak gas. The main drawback is that it is difficult to properly insert the tracheal tube, which is a technical requirement for the actual operator. In addition to this major drawback, there are other drawbacks associated with tracheal tubes. For example, tracheal tubes often cause severe "sore throats" to the patient. This "sore throat" is primarily caused by friction between the tracheal tube and the patient's cartilage tissue, and can also cause a severe choking reaction in the patient. In contrast to the tracheal tube, laryngeal mask airway devices are easier to insert into a patient to establish a breathing passage. In addition, the reason why a laryngeal mask airway device is a "affordable" device is that: the laryngeal mask airway device can establish a breathing passage even if it is inserted incorrectly. Thus, laryngeal mask airway devices are often considered to be a "life saving" device. In addition, the laryngeal mask airway device may be inserted with only minor manipulations of the patient's head, neck, and mouth. In addition, the laryngeal mask airway device does not require contact with the sensitive interior passageway of the trachea to inflate the patient's lungs, and the size of the breathing passage established by the laryngeal mask airway device is significantly larger than the size of the breathing passage established by the tracheal tube. The main defects of the laryngeal mask airway device are that the cost is high, the air leakage is caused by the excessively low sealing pressure, the requirement on the body position of a patient is high, and the control airway failure is caused by the easy displacement of the patient with other special body positions. The prior tracheal tube ventilation device and the laryngeal mask ventilation device are independent auxiliary breathing devices, the mutual replacement of the two devices is very inconvenient, and a series of complications caused by high-sensitivity reaction of an airway due to early anesthesia extubation are easily caused when the breathing mode is switched, so that unpredictable adverse factors exist in the operation. Although the endotracheal tube is not completely built in the laryngeal mask tube, the endotracheal tube is easily detached during the actual tube replacement operation, and the insertion operation of the endotracheal tube is inconvenient, although the endotracheal tube is built in some patent documents, such as chinese patent ZL02819802.6 and US patent US 5303697.

At present, a convertible combined ventilation device with a built-in endotracheal tube and a laryngeal mask is disclosed in the chinese patent with the application number of cn201410043219.x, which comprises a laryngeal mask and an endotracheal tube, wherein the front end of the endotracheal tube is inserted into the laryngeal mask endotracheal tube from the distal end of the laryngeal mask endotracheal tube, and the endotracheal tube can freely slide in the laryngeal mask endotracheal tube by pushing the rear end of the endotracheal tube; although the invention can convert different ventilation modes, the invention needs to assist the laryngeal mask catheter with hands to control the extension and retraction of the endotracheal tube after the laryngeal mask is worn, the position of the laryngeal mask is easily influenced, the laryngeal mask is deviated, and the patient can not be effectively ventilated when the laryngeal mask is ventilated.

Based on the above, the invention designs a built-in type tracheal catheter and laryngeal mask combined ventilation device for general anesthesia to solve the above problems.
