Description
Technical field
The invention belongs to clinical treatment equipment technology field, more particularly to a kind of zero dead space tracheal catheter respiratory 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
Physiological dead space and mechanical inefficiencies chamber.Physiological dead space includes bronchus, tracheae, oral cavity, nasal cavity；Mechanical inefficiencies chamber includes gas
Capsule gas tube, tracheal catheter, breathes breathing circuit filter, breathing circuit breeches joint.In each respiratory, exhalation process row
The exhaust gas section gone out rests on dead space, and breathing process can suck human body again, cannot get gas exchanges.
Clinically, breathing dead space problem can not avoid, and physiological dead space is adapted to by patient, and anesthesia is not influenced；
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 two kinds of sides of autonomous respiration and Mechanical course breathing
Formula.Autonomous respiration refers to patient and is breathed by itself strength, due to the respiration inhibition effect of arcotic and depositing for 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；Machinery
Control breathing refers to patient's autonomous respiration pause, carrys out assisted respiartion by lung ventilator, and due to the presence of mechanical inefficiencies chamber, lung ventilator needs
The throughput and airway pressure of bigger, or faster respiratory rate are provided to maintain effectively to breathe, causes respiratory tract and lung to damage
The risk of wound.The capacity of mechanical inefficiencies chamber is from tens milliliters to milliliters up to a hundred etc..Breathed every time often only in infant's anesthesia
There are tens milliliters of gases, due to the presence of mechanical inefficiencies chamber, make to suck in gas that to have close to half be oneself discharge but not every time
Exhaust gas through absorbing and filtering；Although will not anoxic, carbon dioxide in blood can be made to raise and bring adverse reaction.Elimination machine
Tool dead space, respiration inhibition caused by can alleviating anaesthetic in the general anesthesia for retaining autonomous respiration, improves work of breathing
Can, body acid-base imbalance is corrected, and then improve vital sign situation；Ventilation can be reduced in the general anesthesia of control breathing
Amount, reduces pressure in respiratory tract, slows down respiratory rate, reduces respiratory system damage.Patient age weight is smaller, physical condition
Poorer, operating time is longer, and the clinical meaning for eliminating mechanical inefficiencies chamber is bigger.
