[0007] 3. When using traditional simple respirators,
medical staff usually need to fix the
mask with one hand and squeeze the simple respirator with the other hand to realize the process of
inhalation and
exhalation. For some larger balloons, nurses generally cannot control them with one hand. Two hands are required to squeeze, which leads to the need for two people to cooperate to complete the work, and the work efficiency is not high
[0008] 4. During the use of the existing simple respirator, the medical staff fix the
mask with one hand and squeeze the
airbag with the other hand. The
inhalation and
exhalation process is realized by the medical staff manually squeezing the
balloon of the simple respirator. The
tidal volume is accurately controlled, the operation is difficult, and the effect is difficult to guarantee
[0009] 5. During the use of the traditional simple respirator, the medical staff manually press the
airbag. Due to the repeated operation, the balloons of the simple respirator are mostly smooth, which is not conducive to holding the operation with one hand, which may cause the
airbag to be distorted by the medical staff. The falling off of the hands of the personnel affects the use of the simple respirator and the uniform and continuous
oxygen supply, which is inconvenient in use
[0010] 6. It is difficult to control the frequency and time of extruding the
balloon with the traditional simple respirator, which will affect the uniformity and continuity of the supply. Patients are prone to shortness of breath and decreased blood oxygen. The doctor’s
response time is not accurate when pinching the
balloon, resulting in too fast pinching speed, so that the patient has no
breathing time at all, and the patient is wearing an
oxygen mask and cannot speak. If the patient is very painful and restless, the
heart rate is too fast or the rapid
atrial fibrillation occurs seriously, which seriously affects the quality of
anesthesia operation
[0011] 7. At present, there is
no storage device for simple respirators. It is inconvenient to take and carry simple respirators. Since the balloons of simple respirators are usually made of rubber or
plastic materials, the balloons are squeezed during carrying and storage. If it is not fully inflated in clinical use, it will directly affect the
tidal volume generated during compression, and it will be difficult for medical staff to judge the amount of gas discharged, which will eventually lead to unstable
tidal volume. affect the rescue effect
[0012] 8. During the use of the simple respirator, the
oxygen mask is in direct contact with the patient. The existing simple respirator does not have a fixed storage device, and the
oxygen mask may be polluted during storage, carrying, and use. If the patient comes into direct contact with the contaminated oxygen mask, causing
respiratory infection, etc., the consequences are extremely serious
[0013] 9. In the process of traditionally using simple respirators, the patient's head needs to be kept tilted backwards, and the lower
forehead needs to be turned upwards to keep the
airway unobstructed. Generally, patients in a crisis state cannot take the initiative To complete the above actions, the medical staff dragged them firmly by hand. During the process of transporting patients, the operation difficulty increased, which would cause the hand nerve fatigue of the medical staff for a long time, increase the work intensity of the medical staff, and possibly Unsmooth
gas transmission occurs, which affects the use effect of simple respirators
