Description

Guidance and respiratory system for digestive endoscopy

Technical Field

The present application relates to the field of medical devices, and more particularly to a guidance and respiratory system for gastrointestinal endoscopy.

Background

With the continuous development of medical technology, endoscope technology plays an increasingly important role in medical diagnosis and treatment. There are often problems during the operational use of an endoscope. First, the endoscope operation requires a high skill and experience of the operator, and the operation difficulty is high because the endoscope pipeline is a hose.

Because the endoscopic procedure requires careful observation and recording of the condition of the organ, the examination time is long and the patient is painful. In order to alleviate pain in the endoscopy of patients, generally, painless anesthesia is used in the endoscopy, and at this time, it is often necessary to use an inner mirror cover for the patients to supply oxygen, which supplies oxygen through a side opening, and can perform appropriate pressurized oxygen supply or direct oxygen supply, so as to ensure safety after anesthesia or sedative administration to the patients, thus effectively reducing discomfort and pain of the patients.

However, the distance between the endoscope inlet and outlet on the existing endoscope cover and the operation opening on the patient bite pad is far, and because the endoscope pipeline is a hose, the operator cannot control the advancing direction of the pipeline, the operation difficulty of the operator is greatly increased by the long-distance pipe feeding operation, the endoscope pipeline enters the alimentary canal through the endoscope inlet and outlet after passing through the mask cavity and the operation opening of the bite pad, and interference between the endoscope pipeline and respiratory gas is necessarily generated in the process. In the case of endoscopy of a patient, if an emergency such as hypoxia occurs, normal ventilation and oxygen supply to the patient during the use of the endoscope cannot be ensured.
