Description
技术领域technical field
本实用新型涉及医疗技术领域，特别是涉及一种具有辅助吸痰装置的氧气面罩。The utility model relates to the field of medical technology, in particular to an oxygen mask with an auxiliary sputum suction device.
背景技术Background technique
目前，在临床上当患者出现呼吸困难需要进行吸氧时都会使用到医用面罩。现有的医用面罩一般包括一个面罩本体，面罩本体上开设有进气口、吸气口。其中：进气口可以连接诸如雾化器接口、氧气管接口等，吸气口罩在使用者的面部。At present, clinically, medical masks are used when patients have difficulty breathing and need to inhale oxygen. Existing medical masks generally include a mask body, and the mask body is provided with an air inlet and an air suction port. Among them: the air inlet can be connected to such as the nebulizer interface, the oxygen tube interface, etc., and the inhalation mask is on the user's face.
有些患者会出现痰液增多的现象，过多的、粘稠的痰液阻塞了呼吸道，妨碍了气体进出呼吸道，因而，保持呼吸道通畅是抢救呼吸衰竭患者的首要措施，重症患者往往无力咳痰，需要用负压抽吸，才能将痰液清除，无创通气后，面罩的使用，使吸痰无法进行，因为，要想吸痰，必须取下面罩，但是，取下面罩就等于中断了通气过程，反复多次吸痰，就要多次中断通气过程，对病情的恢复不利，同时，也使护士工作量大大增加。Some patients will experience increased sputum. Excessive and viscous sputum blocks the airway and prevents gas from entering and exiting the airway. Therefore, keeping the airway unobstructed is the primary measure to rescue patients with respiratory failure. Severe patients are often unable to cough up sputum. Negative pressure suction is needed to remove sputum. After non-invasive ventilation, the use of a mask makes it impossible to carry out sputum suction, because if you want to suck sputum, you must take off the mask, but taking off the mask is tantamount to interrupting the ventilation process , Repeatedly sucking sputum for many times will interrupt the ventilation process many times, which is unfavorable to the recovery of the condition, and at the same time, the workload of the nurses is also greatly increased.
目前，有些面罩上会预留吸痰孔，供吸痰管插入；但是，吸痰管单独插入的时候其插入方向以及插入口中的时候都会遇到阻力，需要医护人员不断调整插入方向以及唤醒患者使其口张开以便于吸痰管的插入，其不仅工作程序繁琐，而且工作效率低下，会应该呼吸衰竭患者的快速吸痰操作。At present, some masks reserve a suction hole for the insertion of the suction tube; however, when the suction tube is inserted alone, the insertion direction and the insertion into the mouth will encounter resistance, requiring medical staff to constantly adjust the insertion direction and wake up the patient. Its mouth is opened to facilitate the insertion of the suction tube, which not only has cumbersome work procedures, but also has low work efficiency, which will be a fast suction operation for patients with respiratory failure.
综上所述，目前亟需设计一种克服上述技术问题的具有辅助吸痰装置的氧气面罩。In summary, there is an urgent need to design an oxygen mask with an auxiliary sputum suction device that overcomes the above-mentioned technical problems.
