Description
Technical field
The invention belongs to clinical treatment equipment technology field, more particularly to a kind of zero dead space drainage laryngeal mask breathing system
System.
Background technology
Clinically, dead space also known as breathes dead space, refers to the space for not participating in gas exchanges in respiratory, including life
Manage dead space and mechanical inefficiencies chamber.Physiological dead space includes bronchus, tracheae, oral cavity, nasal cavity；Mechanical inefficiencies chamber leads to including laryngeal mask
Tracheae, tracheal catheter, breathe breathing circuit filter, breathing circuit breeches joint.In each respiratory, exhalation process discharge
Exhaust gas section rests on dead space, and breathing process can suck human body again, cannot get gas exchanges.
Clinically, breathing dead space problem can not be avoided, and physiological dead space is adapted to by patient, and anesthesia is not influenceed；
It is urgently to be resolved hurrily as one in clinical anesthesia how harmful effect that mechanical inefficiencies chamber or reduction mechanical inefficiencies chamber bring is eliminated
The problem of.At present, breathing pattern of the patient under generalized anesthetic state is divided into autonomous respiration and Mechanical course breathing two ways.
Autonomous respiration refers to patient and breathed by itself strength, because the respiration inhibition of arcotic acts on the presence with mechanical inefficiencies chamber,
It can raise gas concentration lwevel in blood samples of patients, show as blood pressure rise, increased heart rate, respiratory rate is accelerated；Mechanical course
Breathing refers to patient's autonomous respiration pause, carrys out assisted respiartion by lung ventilator, due to the presence of mechanical inefficiencies chamber, lung ventilator need to provide more
Big throughput and airway pressure, or respiratory rate maintains effectively to breathe faster, there is the wind for causing respiratory tract and injury of lungs
Danger.The capacity of mechanical inefficiencies chamber is from tens milliliters to milliliters up to a hundred.Breathing often only has tens every time in infant's anesthesia
Milliliter gas, due to the presence of mechanical inefficiencies chamber, make suck in gas that to have close to half oneself discharged but without absorption every time
The waste gas of filtering；Although will not anoxic, carbon dioxide in blood can be made to raise and bring adverse reaction.Eliminate mechanical inefficiencies
Chamber, respiration inhibition caused by can alleviating anaesthetic in the general anesthesia for retaining autonomous respiration, improve respiratory function, correct
Body acid-base imbalance, and then improve vital sign situation；Throughput can be reduced in the general anesthesia of control breathing, reduction is exhaled
Pressure in road is inhaled, slows down respiratory rate, reduces respiratory system damage.Patient age body weight is smaller, and health is poorer, during operation
Between it is longer, eliminate mechanical inefficiencies chamber clinical meaning it is bigger.
