It is logical.Second opening portion 23 is connect with the nozzle of 1 patient end of tube body, and 22 patient end end face of the first opening portion and the second opening portion
Angle between 23 machine end end faces is 40 °~70 °, and cuff portion 21 is made to be suitable for the inner wall of fitting body cavities, reduces and suffers from
The sense of discomfort of person.Signified patient end and machine end herein are with operator for reference, " patient end " i.e. relative to operator away from
From longer one end, " machine end " is exactly specifically the left end of Fig. 1 and Fig. 2 relative to the shorter one end of operator's distance
And right end.The machine end of tube body 1 can connect laryngeal mask connector 11, and laryngeal mask connector 11 can be with ventilator or Anesthesia machine (not shown)
It is connected.
Please refer to Fig. 1 to Fig. 3, be formed in cuff portion 21 surround the first opening portion 22 cavity 24,3 one end of gas tube with
Cavity 24 connects, and the other end is connect with electronics pressure test device 4, and electronics pressure test device 4 includes pressure sensor 42
With display component 43, pressure sensor 42 is for detecting the air pressure size in gas tube 3 and sending data to display component 43
Display.The use principle of laryngeal mask is: the cuff portion 21 of laryngeal mask can expand to form air bag by inflation after being inserted into person's windpipe
Elastomer is bonded with person's windpipe, plays sealing function, prevents in respiratory gas from the gap of laryngeal mask and tracheal wall
Leakage, is then connect with ventilator to patient ventilation by the laryngeal mask connector 11 on tube body 1.If in the cavity 24 in cuff portion 21
Air pressure it is excessively high, cuff portion 21 can squeeze tracheae and cause tracheae part blood supply disorder, possibly even will lead to cuff portion when serious
21 explosions.The effect of sealing can not be played if the air pressure in the cavity 24 in cuff portion 21 is too low, it cannot be safely to trouble
Person supplies, and which results in medical staff to be worried when using laryngeal mask.The electronics air pressure of laryngeal mask provided by the invention is examined
It surveys device 4 to be connected on gas tube 3, since gas tube 3 connects the cavity 24 in cuff portion 21, the air pressure in gas tube 3 is equal to sky
Air pressure in chamber 24, while the air pressure that can be detected in cavity 24 is arranged on gas tube 3 in electronics pressure test device 4, also not
The insertion of laryngeal mask can be hindered, will not more patient be allowed not feel good.
