Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable oxygen supply mask for anesthesiology. Background Art

[0002] Anesthesia is a comprehensive subject that includes knowledge from multiple disciplines. Now its application scope is wider. It not only meets the requirements of surgery, but also participates in the rescue work of various departments, as well as painless diagnosis and treatment, including painless delivery, painless abortion, painless gastroscopy, painless invasive examination, etc. Since most anesthetic drugs have an inhibitory effect on the patient's respiratory function, patients who need emergency rescue will also have respiratory arrest, and the human body has poor tolerance to hypoxia. Hypoxia of important organs such as the heart and brain is an important cause of death. Therefore, oxygen therapy is very important in surgical anesthesia and emergency rescue. The oxygen mask provides a method to transfer the oxygen needed for breathing from the storage tank to the human lungs. It is an indispensable device in oxygen therapy and plays an important role in ensuring patient safety. Mainly made of plastic, silicone, or rubber;

[0003] In the existing disposable oxygen supply masks, the mask body and the oxygen supply hose are connected by direct plugging, which has the disadvantage of unstable connection and easy to fall off. At the same time, the existing oxygen supply masks are equipped with an elastic ring-shaped headband. When wearing the mask, the ring-shaped headband is put on the head. However, when an unconscious patient lying on the ground or in a bed wears it, in order to put the ring-shaped headband on the head, the head can only be lifted up, but the process of lifting the head is likely to cause other harm to the patient. Therefore, the present application proposes a disposable oxygen supply mask for anesthesiology to solve the above problems. Utility Model Content
