Description

A medical mask with an operating opening

technical field

The utility model relates to the field of medical equipment, in particular to a medical mask with an operating opening.

Background technique

As shown in Fig. 1, the medical mask currently used clinically to implement anesthesia or oxygen supply to patients includes a mask body 1', the upper end of the mask body 1' is provided with a nozzle 11', and the peripheral edge of the lower end of the mask body 1' is provided with a mask body 1'. The ring-shaped mask airbag 2' which is tightly fitted on the periphery of the lower end of the body 1' is provided with an air nozzle 3' on one side of the mask airbag 2' for inflation and deflation. Existing this medical mask has the following deficiencies:

1. When the existing medical mask is used, it covers the patient's mouth and nose at the same time. If the patient needs to perform intraoral surgery or gastrointestinal endoscopy, the medical mask must be taken off, which leads to There is no way to provide anesthesia or oxygen supply at the same time when performing intraoral surgery or gastrointestinal endoscopy, and insufficient oxygen supply will pose a threat to the safety of the patient. At this time, in order to ensure the safety of the patient, the mask oxygen supply can only be provided intermittently, but the intermittent oxygen supply will interrupt the relevant operation or examination, prolonging the operation time or examination time; In the process of internal surgery or gastrointestinal endoscopy, if the patient's blood oxygen drops, the relevant surgery has been carried out to a critical operation or the patient is bleeding; at this time, if the operation or hemostasis is continued, immediate If the patient is supplied with mask oxygen, insufficient oxygen supply will be life-threatening, and if the patient is immediately supplied with mask oxygen, the patient needs to stop the operation or the patient cannot be hemostasis, which may also cause the patient's life-threatening.

2. When the existing medical mask is in use, it covers the patient's mouth and nose at the same time, so it is combined ventilation of the mouth and nose. Because the gas pressures through the mouth and through the nose cancel each other out in the direction of the oropharynx, therefore, The soft tissue of the oropharynx will block the airway downward under the action of gravity, affecting the ventilation efficiency. It is often necessary to raise the jaw to improve the ventilation efficiency (and often the effect is not good). This phenomenon occurs in obesity and sleep apnea syndrome. It is more obvious in patients. The low ventilation efficiency will make the patients unable to ventilate normally and not get enough oxygen supply, thus causing life-threatening.
