Description
技术领域：Technical field:
本发明涉及一种The present invention relates to a 具有自动控制功能的家用吸氧器及其自动吸氧控制方法。A household oxygen inhaler with an automatic control function and an automatic oxygen inhalation control method thereof.
背景技术：Background technique:
为了提高生活质量，有些体质的人需要定时吸氧保健；有的患有某些疾病的患者需要定时吸氧减轻或消除病痛。因此用氧的家庭逐年增多。目前，家庭用氧的主要来源于家用制氧机或家庭自己配备的氧气瓶。而医院则很少应用制氧机，其原因是氧气瓶中的氧气是由专业制氧部门制得，其氧气浓度高达In order to improve the quality of life, some people need regular oxygen inhalation for health care; some patients with certain diseases need regular oxygen inhalation to reduce or eliminate pain. Therefore the family that uses oxygen increases year by year. At present, household oxygen mainly comes from household oxygen concentrators or oxygen cylinders equipped by the household itself. Oxygen generators are seldom used in hospitals, because the oxygen in the oxygen cylinders is produced by a professional oxygen-generating department, and its oxygen concentration is as high as 99%99% ，而制氧机制出的氧气浓度只有, while the oxygen concentration produced by the oxygen generator is only 93%93% 。.
某些心脏病患者的危险时间比较有周期性，其危险时间为凌晨The dangerous time of some heart disease patients is relatively periodic, and its dangerous time is in the early morning 11 时和When and 33 时，上午hour, morning 66 时至time to 88 时，下午的in the afternoon 55 时至time to 77 时，特别是三伏天和三九天的时段心脏病更易发作。如果有预见的吸氧，这可避免危险时段的病痛和心脏病突发的危险。因此定时吸氧就显得尤其重要。Heart attacks are more likely to occur during the dog days, especially during the dog days and three or nine days. If oxygen is given in anticipation, this can avoid the danger of sickness and heart attack during dangerous times. Therefore, regular oxygen inhalation is particularly important.
一般情况下，为降低对氧气的依赖性，在使用瓶装氧气进行吸氧治疗或保健中，氧气的吸入是有时间限定，因此要严格按照规定的时间及时长吸氧。无论是家庭还是医院患者吸氧用，目前应用瓶装吸氧的开始和结束两个操作均由人工完成，完成操作的人可以是吸氧者本人，也可是看护人员，这对于使用者或看护人员来说，在白天是比较容易，但对于夜间吸氧者来说，有时在吸氧的作用下很容易睡着，而清醒的看护人员，熬到吸氧者吸氧结束时往往疲劳不堪，有时由于吸氧者行动不便，此操作必须由看护人员完成，经常发生忘记关闭氧气阀门而发生过量吸氧现象。目前还没有一种应用于氧气瓶吸氧的自动控制装置出现。In general, in order to reduce the dependence on oxygen, in the use of bottled oxygen for oxygen therapy or health care, the inhalation of oxygen has a time limit, so it is necessary to strictly follow the prescribed time and length of oxygen inhalation. Whether it is used for oxygen inhalation by family or hospital patients, the start and end of bottled oxygen inhalation are currently performed manually, and the person who completes the operation can be the oxygen inhaler himself or a caregiver. In general, it is easier during the day, but for oxygen inhalers at night, sometimes it is easy to fall asleep under the action of oxygen inhalation, and the awake caregivers are often exhausted when the oxygen inhalers end. Owing to the inconvenient movement of the oxygen inhaler, this operation must be completed by the caregiver, often forgetting to close the oxygen valve and causing excessive oxygen inhalation. Also do not have a kind of automatic control device that is applied to the oxygen inhalation of the oxygen cylinder to occur at present.

根据实施例According to the embodiment 66 或or 77 所述的具有自动控制功能的家用吸氧器的自动吸氧控制方法，所述的氧气接通的开始时间及接通的持续时间设置具体为：由于控制器没有给出导通信号之前二位二通电磁换向阀一直处于断路状态；按电源开关后，电源指示灯的亮状态显示所述的控制器的电源接通；之后按下模式切换按钮并观察显示屏，使当前状态处于调整氧气接通开始时间，按增按钮或减按钮以达到对氧气接通开始时间的调整，此时第一次开始时间调整完毕，按确认按钮；之后按所述的模式切换按钮，使当前状态处于调整氧气接通持续时间，分别按所述的增按钮和减按钮以达到对氧气接通持续时间长度的调整，此时第一次时间持续长度调整完毕，按所述的确认按钮，以完成第一次氧气接通的开始时间和接通时长调整；按所述的模式切换按钮，进入第二次氧气导通的开始时间和吸氧时长的调整，重复相同的调整过程，直至满足一个时间循环，即In the automatic oxygen inhalation control method of the household oxygen inhaler with automatic control function, the start time and the duration of the oxygen connection are set specifically as follows: since the controller does not give the conduction signal before the two digits The two-way electromagnetic reversing valve is always in the open circuit state; after pressing the power switch, the light of the power indicator light shows that the power of the controller is turned on; then press the mode switch button and observe the display screen, so that the current state is in the state of adjusting oxygen On the start time, press the increase button or the minus button to adjust the start time of the oxygen on, at this time the first start time is adjusted, press the confirm button; then press the mode switch button to make the current state in the adjustment Oxygen connection duration, respectively press the increase button and minus button to achieve the adjustment of the oxygen connection duration length, at this time the first time duration adjustment is completed, press the confirmation button to complete the first Adjust the start time and duration of the second oxygen connection; press the mode switching button to enter the adjustment of the start time and oxygen inhalation time of the second oxygen connection, and repeat the same adjustment process until a time cycle is met. which is 24twenty four 小时之内的调整。adjustments within hours.
在常闭型二位二通电磁换向阀或者控制器发生故障时，由于常闭型二位二通电磁换向阀是常闭型的，故其一直处于切断状态，此时可以转换成人工控制旁通路以实现氧气的通断操作直至故障排除。When the normally closed two-position two-way electromagnetic reversing valve or the controller fails, since the normally closed two-position two-way electromagnetic reversing valve is normally closed, it is always in the cut-off state, and it can be switched to manual at this time. Control the bypass to realize the on-off operation of oxygen until the fault is eliminated.
