anesthesia mask

Abstract

The invention relates to an anesthesia mask, which effectively solves the problem that the existing anesthesia mask can not take into account anesthesia and oxygen supply and can not eliminate water vapor in the mask; the technical solution includes a mask with an air intake pipe connected to the upper end of the mask , the longitudinal sides of the mask are respectively provided with exhaust and air-drying passages, the air intake pipe is coaxially provided with a main air pipe and the main air pipe is respectively connected with an anesthesia catheter and an oxygen supply pipe, a nasal catheter is provided in the anesthesia mask and an air inlet pipe is provided in the air intake pipe. There is a hose connected to the nasal catheter, and the other end of the hose is connected to a dehumidification device. When the water vapor content in the anesthesia mask is too high, the hose is connected to the main trachea. At this time, the dehumidification device will discharge the water vapor in the anesthesia mask to the outside. The outside air continuously enters the mask through the queuing air-drying channel, so as to realize the effect of discharging the air with high humidity inside the mask from the mask. The anesthesia mask has high flexibility, convenient operation and strong practicability.

[0002] The anesthesia mask is a medical emergency equipment used in conjunction with an anesthesia machine and a ventilator. It implements anesthesia gas delivery for patients to inhale anesthesia gas. pain, so that the operation can be carried out smoothly. At present, clinically, the anesthesia mask used for general anesthesia induction and first aid recovery includes a mask body, an air inlet at the upper end of the mask body, and a ring-shaped airtight mask airbag at the lower end of the mask body. , usually after the gas anesthesia is completed on the patient, it is difficult for the patient to breathe spontaneously due to general anesthesia. At this time, the patient must be supplied with oxygen. Usually, the doctor takes off the anesthesia mask and replaces the patient with oxygen Masks or nasal cannula for patients to continue to deliver oxygen to patients, but this operation is cumbersome and brings unnecessary workload to doctors;

[0003] Oxygen supply by oxygen masks can effectively and quickly increase the saturation of blood samples and improve the hypoxic state of patients. It is mostly used for coma and severe patients. Therefore, when patients undergo general anesthesia, most of them will use oxygen masks for oxygen supply, but oxygen Oxygen is supplied to the patient in the form of a face mask. Due to the certain sealing performance of the oxygen mask, the water vapor generated by the patient's breathing stays in the oxygen mask and is adsorbed on the inner wall of the oxygen mask, and cannot be discharged outside. The adsorption on the inner wall of the oxygen mask A large amount of water vapor can easily make patients uncomfortable, and if the water vapor adsorbed on the inner wall of the oxygen mask is not discharged from the mask in time, more and more water vapor will condense into water droplets as time goes by On the patient's face, in severe cases, it may enter the trachea along with the patient's respiratory tract, causing hidden dangers to the patient's life safety; if the nasal catheter is used to supply oxygen to the patient, the catheter is placed directly in the patient's nose, but the oxygen inhalation method of the nasal catheter Lead to more oxygen leakage, resulting in a waste of oxygen;

[0004] Since the operation generally lasts for a long time, the patient needs to continue to supply oxygen for a long time. No matter which of the above methods is adopted, it is not conducive to the operation, the comfort of the patient's body and the safety of life. In view of the above, we provide an anesthesia mask to solve the problem. above question
