Description
Technical field
The utility model relates to laryngeal mask technical field more particularly to inflation-free laryngeal masks.
Background technique
Laryngeal mask is that clinic is succeeded in developing and be used for the mid-80, is introduced the domestic nineties.At present to the use of laryngeal mask
It makes great progress, will be used wider and wider.Laryngeal mask is applied in general anesthesia operation, and effective hand of pressure-relief vent is established
Section.First and second generation laryngeal mask has many advantages: (1) using simply, can establish artificial airway rapidly；(2) it is high to place success rate,
The success rate of unbred medical staff is 87%, total success rate 99.81%；(3) ventilation is reliable；(4) throat and tracheae are avoided
Mucosa injury；(5) stimulation is small, and cardiovascular response is small；(6) it can be used for first aid.But one or two traditional generation laryngeal masks and respiratory tract are close
Not exclusively, oral secretion increases envelope, and Yi Yiwei can not be effectively isolated respiratory tract and alimentary canal, can cause gaseous distention, when serious
It concurrently backflows or accidentally inhales, limit its application in clinical anesthesia.Proseal Laryngeal Mask Airway is in laryngeal mask in 2000 by inventor
Brain is designed and is used for clinic；Recently as the progress of material and technology, there are a variety of follow-on Proseal Laryngeal Mask Airways,
The Splendid laryngeal mask of the two-tube laryngeal mask of such as hunchbacked people, Jin Erkang.Proseal Laryngeal Mask Airway inherits many advantages of one or two generation laryngeal masks,
Have the characteristics that oneself simultaneously, mainly have: (1) supervisor has the design of snorkel and drainage tube, drainage tube can in 90 degree of bendings
It is inserted into stomach tube and drains gastric juice, prevent from gaseous distention and backflow accidentally to inhale；(2) double bolloon designs, and vent hood is more matched with bottleneck throat dissection,
Better tightness；(3) laryngeal mask distal end is located at oesophagus opening, fixes, is not easy to shift.Clinical research shows to make in clinical operation
With Proseal Laryngeal Mask Airway have it is easy to operate, set that pipe success rate height, hemodynamic stability, induction period medication are few and occur concurrently
The few advantage of disease, validity and safety greatly improve, and are easy to promote and apply in clinical anesthesia.Indication: having in brief,
Patient with general anesthesia, the patient of emergency department, ICU and each department's first aid and recovery, difficult airway.
When in use, user may feel pain to laryngeal mask, therefore the tracheae on laryngeal mask can be stung with tooth, such one
Come, not only injures tooth, it is also possible to which tracheae of breaking by the teeth causes laryngeal mask ineffective, therefore, in order to solve problems, Wo Menti
Inflation-free laryngeal mask is gone out.
