Description

Oxygen mask and oxygen delivery system for anesthesia

technical field

The utility model belongs to the technical field of medical devices, in particular to an anesthesia oxygen delivery mask and an oxygen delivery system.

Background technique

Painless technology has been widely used in many medical diagnosis and treatment methods. During the implementation of painless technology, due to the application of intravenous anesthetics, it will inevitably cause different degrees of respiratory depression, and even apnea. Oxygen has become a necessary safety guarantee for painless techniques.

The prior art discloses a new type of mask device for hospital anesthesia, which includes a mask body, a connecting pipe connected to the mask body, and a one-way valve connected to the bottom of the mask body. The wetting part is connected to the mask body, the connection between the two wetting parts is connected to the storage part for storing the wet liquid, and the storage part is connected to the mask body. When the patient is under anesthesia, by wearing the mask body, the medical staff can squeeze out the wet liquid inside the storage part through the set wet part, and the two wet sponges set at the wet part contact with the patient's nasal cavity, increasing The humidity of the patient's nasal cavity can avoid the stinging and damage of the patient's nasal cavity when the patient enters the dry air for a long time.

In combination with the instructions and accompanying drawings, the connecting tube is used to deliver oxygen to the patient, the wet part is used to increase the humidity of the patient's nasal cavity, the wet part and the connecting tube are independently arranged, and the wet part is a wet sponge. Since the size of the nasal cavity of each patient (including anesthetized patients) is different, each patient chooses the size of the moist sponge differently. Accordingly, if the volume of the moist sponge is too large, it may block the patient's nasal cavity, making it impossible to treat the patient. Normal oxygen delivery will pose a threat to the patient's life safety; if the volume of the moist sponge is too small, the area that can moisten the nasal cavity will be relatively small, so that the moisturizing effect is not good.

Therefore, there is a need for a universal device that can simultaneously ensure a good moisturizing effect on the nasal cavity of an anesthetized patient and provide normal oxygen supply to the anesthetized patient.
