Description

A bronchoscopic combined laryngoscope-guided endotracheal intubation system

technical field

The utility model mainly relates to the field of medical equipment, in particular to a bronchoscope combined with a laryngoscope to guide a trachea intubation system.

Background technique

Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest means in respiratory management, and plays a vital role in saving patients' lives and reducing mortality. The use of orotracheal intubation is quick and convenient, and it is more commonly used in the rescue of breathing and cardiac arrest. However, it is more difficult to use orotracheal intubation. In clinical practice, it is often encountered that the difficulty of tracheal intubation leads to the failure of anesthesia and surgery, and even the death of the patient. accident.

At present, many hospitals use bronchoscope and video laryngoscope to solve the clinical difficulties of tracheal intubation. A good helper for doctors and anesthesiologists. Many hospitals in my country, especially primary hospitals below the second level and some tertiary hospitals in the Midwest, are not equipped with bronchoscopes and video laryngoscopes, and there is no escort of bronchoscopes and video laryngoscopes, which greatly increases the work of anesthesiology departments in these hospitals. Therefore, the new tertiary hospital accreditation puts the treatment of difficult airway at the top of the list, and requires the anesthesiology department of the tertiary hospital to have tools for handling difficult airways, such as bronchoscope or video laryngoscope, which shows that bronchoscopic and videolaryngoscope in the management of difficult airways. Although bronchoscope and video laryngoscope are more practical, they cannot be popularized due to some existing problems, such as:

1. At present, bronchoscopes and video laryngoscopes in the medical market are expensive, easily damaged, and expensive to maintain. Due to their high prices, they will inevitably increase the medical expenses of patients, which is difficult for many patients to accept. Therefore, this equipment It cannot be promoted in the majority of primary hospitals.

2. For fiberoptic bronchoscopes, it is easy to cause fiber breakage to form black spots. Electronic bronchoscopes require a special image processing system, which is poor in compatibility and inconvenient to use.

3. The current bronchoscope and video laryngoscope cannot be used in combination, so learn from each other.
