The anaesthesia breathing system is   composed of shell, calibration line, indicator ball, moving slider,   

telescopic pipe, bite and other main accessories. The D-type shell is made of   polystyrene, telescopic tube,

bite, indicator ball and movable slider using   polyethylene as raw material.   

  Anaesthesia breathing system is used to   help patients who have undergone abdominal or thoracic

surgery to improve the depth and duration of breathing. help improve the respiratory function of recovery

lung, reduce and prevent post operative complications.   

3. Exhale deeply and exhale as much air as   possible, then hold the bite, and breathe deeply and evenly so  

that the   indicator ball stays in the middle of the smiling face position, so that the   moving slider rises slowly and remains as long as possible.   

  4. Remove the anaesthesia breathing   system and exhale. Repeat step 3 and step 4 for 10 -15 minutes  

after deep   breathing training. then rest with normal breathing. Users can use   anaesthesia breathing

system for deep breathing exercise, and record the maximum   that can be achieved; patients after surgery

can carry out deep breathing   training under the guidance of medical staft.   

  1. The numerical value indicated on the   deep anaesthesia breathing system represents the suction

velocity required to indicate the ball's ascent. For example "5000ml" means that the suction velocity

needed to make the indicator ball rise is 5000mi per second.   When the indicator ball reaches the top, the

maximum suction velocity is 5000ml. The product of the maximum velocity and duration of the ascending  

indicator ball represents the deep suction volume.   

2. Use anaesthesia breathing system to do deep   inspiration exercise and test record the maximum that  

can be achieved.   

  3. Firstly, set the target value for   each day, then practice at a low flow rate for a certain duration (e.g. more   than 2 seconds, which may take several days, depending on the pulmonary function), and then increase  

the inspiratory velocity after a certain duration for inspiratory training until a high level.   

  4. Maintenance and maintenance methods:   After each use, clean the bite of the deep breathing exercise  

with clean water, dry it and put it back in the bag for reserve.   

  6. This product is mainly used for deep breathing exercise and testing, but it is not a professional  

pirometer. The   product surface scale is reference value, only for reference.
