Description

Painless gastroscope anaesthetic mask

Technical Field

The utility model relates to the field of medical instruments, in particular to an anesthesia mask for a painless gastroscope.

Background

In the development of painless gastroscopy, an anesthesiologist is required to administer intravenous anesthesia to a patient. The traditional injection anesthesia mode not only has complicated operation and increases the working intensity of medical staff, but also brings pain to patients and generates the preoperative nervous mind. In addition, due to the respiratory function inhibition by intravenous anesthetic drugs, respiratory inhibition is caused to varying degrees after intravenous anesthetic drugs are administered to patients. When respiration inhibition occurs, the gastroscope can only be pulled out, and the patient can be controlled to breathe by using a common mask so as to ensure safety, which is the bottleneck of popularization of the painless gastroscope. Therefore, a new painless gastroscopic anaesthetic mask is needed.

To facilitate understanding of the working principle of the present embodiment, the working process of the present invention is briefly described as follows: first, the nose and mouth of the patient are covered with the mask body 1, and the breathing tube 6 is aligned with the nasal cavity of the patient. Next, the mouth ring 8 is inserted into the patient's mouth to set up the teeth, and the tongue of the patient is pressed by the tongue-pressing piece 9 to prevent the tongue from being lifted. Then, the mask body 1 is fixed to the head by a connecting band, and the breathing tube 6 is connected to an oxygen supply device, which may be a simple respirator or an oxygen inhalation connecting tube. When the flow of the anesthetic agent introduced into the mask body 1 through the delivery tube 2 needs to be adjusted, the number of the minute holes 300 communicating with the breathing tube 6 can be changed by rotating the flow adjusting part 4 to adjust the flow of the anesthetic agent introduced into the mask body 1 according to the condition of different patients. For example, the medical staff may rotate the flow regulating part 4 clockwise to make the flow regulating part 4 gradually move to the bottom of the through hole in the connecting part 3, so that the number of the micropores 300 communicated with the breathing tube 6 is reduced until completely absent, i.e. the flow of the anesthetic drug is gradually reduced to zero; and vice versa. Rotating the flow regulating part 4 counterclockwise can gradually increase the number of the minute holes 300 communicated with the breathing tube 6, that is, the flow of the anesthetic agent is gradually increased. After the patient is completely anesthetized, the gastroscope can be inserted into the gastroscope tube 7 from the gastroscope aperture 100 and then into the patient, and the gastroscopy can be started.

It should be noted that the above-mentioned embodiments are exemplary, and that those skilled in the art, having benefit of the present disclosure, may devise various arrangements that are within the scope of the present disclosure and that fall within the scope of the utility model. It should be understood by those skilled in the art that the present specification and figures are illustrative only and are not limiting upon the claims. The scope of the utility model is defined by the claims and their equivalents.
