The technical problem to be solved by the utility model is to provide a mask for a non-invasive ventilator to solve the problem that the current traditional mask has a simple structure and a single function, which causes harm to the patient and reduces the treatment effect of the patient.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: a mask for a non-invasive ventilator, including a mask, a first give way slot, a placement slot, an air cushion, an inflatable tube, a regulating valve, a strap, a second give way slot, an inlet Trachea, exhaust pipe, the first relief slot is located at the upper end of the mask, the first relief slot is integrally connected with the mask, the placement slot is located inside the mask and the first relief slot, and the The placement slots are integrally connected with the mask and the first relief slot respectively, the air cushion is located inside the placement slot, one end of the air cushion is connected to the placement slot with glue, the inflation tube runs through the front end of the mask, and the inflation tube and the air cushion Glue connected, the regulating valve is located on the outer wall of the inflation pipe, the regulating valve is connected with the thread of the inflation pipe, the strap is located on the left side of the mask, the two ends of the strap are connected with the rivets of the mask, the first The second relief groove is located at the front and rear ends of the strap, the second relief groove is integrally connected with the strap, the air intake pipe runs through the middle end of the right side of the mask, and the air intake pipe is integrally connected with the mask. The exhaust pipe runs through the lower end on the right side of the mask, and the exhaust pipe is integrally connected with the mask.

Further, the right side of the intake pipe is also provided with a telescopic hose, and the telescopic hose is connected with the intake pipe by glue.

Further, the outer wall of the intake pipe is also provided with a first one-way valve, and the first one-way valve is threadedly connected with the intake pipe.

Further, the right side of the flexible hose is also provided with a connecting pipe, and the connecting pipe is connected with the flexible hose by glue.

Further, the outer wall of the exhaust pipe is also provided with a second one-way valve, and the second one-way valve is threadedly connected with the exhaust pipe.

Further, a snap ring is provided at the front end of the outer wall of the mask, and the snap ring is threadedly connected with the mask, and the snap ring is connected with the inflatable tube by a buckle.

Compared with the prior art, when using the mask for non-invasive ventilator, firstly, the medical personnel put the bandage on the head of the patient with their hands, and then put the second relief groove at the position of the patient's ear, so as to prevent the bandage from being The patient's ears are pressed to protect the patient. The medical staff then places the mask on the patient's mouth and nose. Through the function of the first relief groove, the mask gives way to the patient's nose bridge. The straps have The elastic function can adjust the tightness according to the size of the patient's head. Under the action of the strap, the mask is firmly connected to the patient. The medical staff then connect the inflatable tube with the external inflatable device such as an inflatable air bag by hand. Then open the regulating valve by hand, and the medical staff will use the inflatable air bag again, so that the inflated gas is discharged into the air cushion from the inflatable tube, so that the air cushion is in an inflated state. The purpose is to make the inflated air cushion meet the patient's face and nose bridge, so that the mask is in soft contact with the patient's face and nose bridge. At the same time, the inflation of the air cushion is effective The parts where the mask meets the patient's face and the bridge of the nose are sealed to ensure the tightness of the connection between the mask and the patient. When the inflated state of the air cushion meets the needs of the medical staff, the medical staff stop using the inflatable air bag. The medical staff first Close the regulating valve by hand to prevent the inflated gas in the air cushion from being discharged from the inflatable tube. The medical staff then separate the inflatable air bag from the inflatable tube, and then snap the inflatable tube into the snap ring. The medical staff then connect the connecting tube with the non-invasive ventilator. After connecting, the medical personnel turn on the non-invasive ventilator again. At this time, the oxygen generated by the non-invasive ventilator is discharged into the flexible hose through the connecting tube, then discharged into the air intake pipe through the flexible hose, and then discharged into the mask through the air intake pipe. Perform non-invasive respiratory therapy on the patient. When the gas after the patient’s breathing, that is, carbon dioxide gas, is discharged from the patient’s body into the mask, due to the function of the first one-way valve, the carbon dioxide gas will not be discharged into the intake pipe. At this time, the carbon dioxide gas The gas is discharged from the exhaust pipe to the outside world, ensuring the stability of the patient's non-invasive respiratory treatment. The mask for the non-invasive ventilator has an ingenious structure, powerful functions, and simple operation. By using the device, the patient's face and bridge of the nose are in a soft position with the device. The state of contact can effectively prevent the occurrence of pressure sores on the patient's face and bridge of the nose. At the same time, the inflated air cushion can be firmly attached to the patient's face through the inflated air cushion in contact with the patient's face to prevent leakage. The occurrence of gas and other phenomena effectively improves the treatment effect of patients. At the same time, the second one-way valve is to prevent the external gas from being discharged into the mask from the exhaust pipe and affect the treatment effect of the patient. When the swing occurs, the telescopic hose and the connecting pipe will swing synchronously through the action of the telescopic hose, preventing the swinging connecting pipe from driving the intake pipe and the mask to swing and causing the mask to separate from the patient's face, ensuring the stability of the patient's treatment.
