Medical mask with operation opening

Abstract

The invention discloses a medical mask with an operation opening. The mask comprises a mask body, the upper end of the mask body is provided with a pipe orifice, the peripheral edge of the lower end of the mask body is provided with an annular mask airbag which sealingly matches with the peripheral edge of the lower end of the mask body, the mask airbag is provided with an air tap extending downwards, the upper end of the mask body is provided with an operation opening corresponding to the human body mouth, the operation opening is provided with a extends downwardly with a tooth pad tube, andthe tooth pad tube is detachably fitted with an gas leak-proof sealing valve used for sealingly matching with a gastrointestinal endoscope body. The mask enables patients to perform oral surgery or endoscopy while performing oxygen supply or anesthesia.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical mask with an operation opening. Background technique [0002] Cooperate figure 1 As shown, at present, the medical mask used for clinically implementing 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 nozzle 11' connected with the mask body 1'. The ring-shaped mask airbag 2' which is tightly matched with the periphery of the lower end 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: [0003] 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, w...

Problems solved by technology

[0003] 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 Provide oxygen to the patient with a face mask. Insufficient oxygen supply to the patient will be life-threatening. If the patient is immediately supplied with mask oxygen to the patient, the operation must be stopped or the patient cannot be hemostasis, which may also cause life-threatening danger to the patient.

[0004] 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 the patient. The low ventilation efficiency will make the patient unable to ventilate normally and not get enough oxygen supply, thus causing life-threatening
