[0002] Currently, non-invasive ventilator ventilation is a non-invasive ventilation method between oxygen inhalation and endotracheal intubation. It can greatly improve the patient's oxygenation, reduce dyspnea and respiratory muscle fatigue. The non-invasive ventilator mask is the key part of the connection between the patient and the machine. In clinical practice, it has been found that the airway of patients with respiratory failure cannot be opened well when using non-invasive ventilators. Long-term use cannot achieve the ideal effect, which increases the patient's pain. If the patient has sputum sounds and needs suctioning, it is necessary to find a time when the patient is stable to remove the mask, and then quickly suction the sputum from the mouth and nasal cavity before putting the mask back on.

[0039] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] See Figures 1 to 7 The present invention relates to a specific embodiment of a non-invasive ventilator mask for opening the airway and suctioning sputum. The existing non-invasive ventilator mask cannot open the patient's airway well when the non-invasive ventilator is used to treat patients with respiratory failure. Long-term use cannot improve the patient's oxygenation and cannot achieve the ideal treatment effect. In addition, if the patient needs suctioning when he has sputum sounds, it is necessary to find a time when the patient is stable to remove the mask, and then quickly suction the sputum in the mouth and put the mask back on, which increases the patient's pain. In addition, taking off the mask will cause the patient to be under-supplied with oxygen, which can easily endanger the patient's life. Therefore, by designing the non-invasive ventilator mask for opening the airway and suctioning sputum, the problem that the existing ventilator mask needs to be removed for suctioning, which easily increases the risk of insufficient oxygen supply to the patient, and the patient's airway cannot be opened well, resulting in worsening of the condition, is solved.

[0041] like Figures 1 to 3 As shown, in this embodiment, the non-invasive ventilator mask for opening the airway and suctioning sputum includes a mask body 1, a pipe connector 3 installed on the mask body 1 and connected to the non-invasive ventilator, a binding belt 4 for fixing the head, and also includes a rotatable suction plug pipe 11 arranged on the top of the mask body 1 and passing through the mask body 1. A detachable oral ventilation tube 2 is provided inside the mask body 1, which is connected to the suction plug pipe 11. A retractable catheter 12 is provided in the suction plug pipe 11. Preferably, by rotating the suction plug pipe 11 unscrews the catheter 12 so that the catheter extends inward to form a sputum suction plug pipe 11, which is connected to the oral ventilation tube 2. The external sputum suction tube is smoothly inserted into the patient's airway through the catheter 12 and the oral ventilation tube 2 to suction sputum. The non-invasive ventilator mask is provided with a sputum suction plug pipe 11 on the top of the mask body 1. When the patient has sputum sound and needs to suction sputum, the sealing cap 111 on the sputum suction plug pipe 11 is opened, the catheter 12 located in the sputum suction plug pipe 11 is pushed out, and the cross-shaped sealing valve 121 (as described below) can be inserted. Figure 7As shown in the figure, the sealing of the mask body 1 is ensured by the cross-shaped sealing valve 121, the sputum suction tube is passed from the cross-shaped sealing valve 121 to the catheter 12, and then guided to the oral ventilation tube 2 through the catheter 12, and the sputum suction tube is extended into the patient's airway through the oral ventilation tube 2 connected to the catheter 12 to suction sputum. After the sputum suction is completed, the sputum suction plug pipe 11 is rotated to retract the catheter 12, and the sealing cap 111 on the sputum suction plug pipe 11 is covered; during this process, there is no need to take off the mask, the patient can breathe oxygen normally, and the oral ventilation tube 2 is detachably arranged in the mask. When the patient wears the mask, the patient's airway is kept open through the oral ventilation tube 2, so that the treatment achieves better results and facilitates sputum suction to relieve the patient's pain.

[0042] Specifically, if Figure 5 and Figure 6 As shown, the oral ventilation tube 2 includes a tube body 21 with openings at both ends, a flange 22, a tooth pad 23, and the flange 22 is formed at one end of the tube body 21. The tooth pad 23 is arranged in one end of the tube body 21 and nested in the flange 22. The bend of the tube body 21 forms a pharyngeal bend 211. Soft wires 24 are respectively provided on both sides of the oral ventilation tube 2. One end of the soft wire 24 is connected to both sides of the flange 22, and the other end of the soft wire 24 is connected to the inner wall of the mask body 1. Hooks 13 are respectively provided on both sides of the mask body 1 to connect and fix with the soft wire 24. The oral ventilation tube 2 keeps the patient's airway open and is connected and fixed to the hooks 13 on the inner wall of the mask through the soft wire 24.

[0043] Preferably, the oral ventilation tube 2 is an elliptical tube body 21 or a rounded rectangular tube body 21 as a whole. The shape of the tube body 21 fits the geometric structure of the human mouth, trachea and airway. The pharyngeal bend 211 is formed at the bend of the tube body 21, and the pharyngeal bend 211 bends downward and extends into the throat. The flange 22 is located at one end of the tube body 21 and is the outer edge of the elliptical tube body 21. The flange 22 and the tube body 21 are cast in an integral manner. The tooth pad 23 is nested at the end of the tube body 21 with the flange 22 to prevent the patient from biting the oral ventilation tube 2, causing the oral ventilation tube 2 to close or be damaged.

[0044] It can be understood that the catheter 12 and the suction plug pipe 11 can be set to be slidingly connected or one end of the catheter 12 can be fixed in the suction plug pipe 11. By setting the catheter 12 as a catheter 12 with variable length and telescopic deformation, one end of the catheter 12 extends out of the suction plug pipe 11 and is connected to the oral ventilation tube. In addition, a sealing cap 111 should be installed on the top of the suction plug pipe 11 to ensure the sealing inside the mask body 1 and to ensure that the oxygen in the mask body 1 is sufficient and will not leak. When in use, open the sealing cap 111, push out the catheter 12, or pull the catheter 12 out of the suction plug pipe 11 and connect it to the oral ventilation tube.

[0045] Specifically, the catheter 12 extends out of the suction plug-in pipe 11, and a cross-shaped sealing valve 121 is inserted into one end of the catheter 12 extending out of the suction plug-in pipe 11. When the catheter 12 is pushed out of the suction plug-in pipe 11, the cross-shaped sealing valve 121 is inserted for further sealing to prevent oxygen leakage in the mask body 1 due to opening the sealing cap 111 and pushing out the catheter 12 during suction. It should be noted that the cross-shaped sealing valve 121 can be set to a structure such as a medical silicone cross valve, and the suction tube can be inserted through the middle cross-shaped structure and maintain a sealing effect.

[0046] It can be understood that the mask body 1 is also provided with a ventilation valve 14, an exhaust hole 15 and an oxygen interface 16. The ventilation valve 14 and the exhaust hole 15 are located on one side of the pipe connector 3, and the oxygen interface 16 is located on the surface of the mask body 1. The sputum suction plug-in pipe 11 can also be inserted into a fiber bronchoscope for suctioning sputum, performing examinations or collecting specimens, etc.

[0047] Preferably, if Figures 1 to 7 As shown, a silicone air cushion 5 is installed on the edge of the mask body 1. The silicone air cushion 5 is sealed and connected to the mask body 1 to the wearer's face by adjusting the amount of gas filled in, and a chamber is formed. The suction tube extends into the chamber based on the catheter 12, and is used to suction the patient's sputum in the sealed and connected chamber. By installing the silicone air cushion 5 on the edge of the mask, the silicone air cushion 5 is sealed and connected to the mask body 1 to the wearer's face by adjusting the amount of gas filled in, ensuring sealing and soft fit, and a sealing cap 111 is provided at the top of the suction plug pipe 11. After opening the sealing cap 111 on the suction plug pipe 11, the catheter 12 is pushed out, and a cross-shaped sealing valve 121 is inserted at the mouth of the catheter 12 to increase its sealing, reduce oxygen leakage, and enable the mask body 1 to suction the patient in a sealed oxygen supply environment.

[0048] It can be understood that after the doctor evaluates the patient's condition, if type II respiratory failure requires a non-invasive ventilator to improve the patient's ventilation function so that the patient can better inhale oxygen and expel carbon dioxide, the oral ventilation tube 2 is immediately inserted into the mask body 1, and the soft wires 24 on both sides of the oral ventilation tube 2 are hung on the small hooks 13 on the bottom of the mask on both sides, and the mask is put on and connected to the non-invasive ventilator with adjusted parameters; if the patient needs sputum suction, an external suction tube can be used, and the device connected to the suction tube can be opened, and the device generates negative pressure to suction sputum. The tube sucks out the sputum in the patient's airway. At this time, the sputum suction plug pipe 11 on the rotating mask body 1 is used to push the catheter 12 out from the sputum suction plug pipe 11 toward the oral ventilation tube 2 in the mask body 1, so as to smoothly insert the sputum suction tube into the patient's airway through the catheter 12 for suctioning sputum. The non-invasive ventilator mask for opening the airway and suctioning sputum can not only well improve the ventilation function, but also effectively suction sputum without removing the mask body 1, thereby alleviating the patient's pain and improving the patient's condition. If the insertion is refused for correction of apnea or some other problems, the oral ventilation tube 2 part can be removed.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which all fall within the scope of protection of the present invention.
