[0005] In order to make up for the above shortcomings, the utility model provides a nasal mask of nasopharyngeal anesthesia of anti - compression, which aims at improving the problem that the nasopharyngeal tube in the prior art can only solve the upper respiratory obstruction caused by tongue falling back and other reasons of the patient, and when the nasopharyngeal tube is used and still cannot relieve the dyspnea and hypoxia, balloon or mechanical assisted ventilation is needed, and at this time, another anesthesia mask needs to be prepared, thereby increasing the complexity and time cost of operation.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a nasal mask of nasopharyngeal anesthesia of anti - compression, including nasopharyngeal anesthesia mask, the outside of nasopharyngeal anesthesia mask is provided with double oxygen supply interface, the outside of double oxygen supply interface is provided with oxygen interface, the top of oxygen interface is fixedly connected with pressing device.
[0007] Further, the front side of the nasopharyngeal anesthesia mask is provided with an anesthesia injection port.
[0008] Further, the nasopharyngeal anesthesia mask is provided with a throat anesthesia delivery tube.
[0009] Further, the outside of the nasopharyngeal anesthesia mask is fixedly connected with an inflation valve.
[0010] Further, the throat anesthesia delivery tube is a replaceable structure.
[0011] Further, the inside of the inflation valve is provided with a flow regulating device.
[0012] Further, the outside of the laryngeal anesthesia delivery tube is provided with an antibacterial layer.
[0013] The utility model has the advantages of the following:
[0014] 1. In the utility model, when oxygen is supplied by the pressing device, medical staff can quickly start oxygen flow. The pressing device is connected to the double oxygen supply interface through the oxygen interface. When pressing, gas is sent to the nasopharyngeal anesthesia mask. By controlling the force and frequency of pressing, medical staff can adjust the flow of oxygen to meet the needs of patients. The nasopharyngeal anesthesia mask can provide high-flow oxygen through the double oxygen supply interface, so that oxygen quickly enters the alveoli and improves oxygen concentration.
[0015] 2. In the utility model, the anesthesia injection port and the replaceable laryngeal anesthesia delivery tube enhance the flexibility and adaptability of anesthesia, facilitate clinical operation, and the combination of the inflation valve and the flow regulating device allows accurate control of gas flow, prevents excessive pressure accumulation in the mask, and thus improves the safety and effect of anesthesia.
