Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to trachea cannula with standard gasbag.
Background
The technology of placing a special endotracheal tube into the trachea through the glottis is called trachea intubation, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like.
The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely applied, most effective and most rapid means in respiratory tract management, is the basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate. And can in time suck out trachea incretion or foreign matter, prevent that the foreign matter from getting into the respiratory track, keep the respiratory track unobstructed, carry out effectual manual work or machinery and ventilate throat physiology and dissect, prevent whether patient's oxygen deficiency and carbon dioxide are detained trachea cannula and in time direct relation to the success of rescue, whether the patient can transport safely and patient's prognosis condition.
Tracheal catheter who uses clinically has the gasbag mostly, and the gasbag is attached to the leak protection device of a tangible structure on tracheal catheter front end lateral wall, and with tracheal catheter disjunctor, mainly be trachea cannula accomplish the back, inflate for the gasbag then can seal the gap between pipe and the tracheal inner wall, air leakage when preventing the malleation ventilation to and avoid upper respiratory secretion or the reflux of gastric content to the trachea in to cause the mistake and inhale.
After the trachea is intubated, the air sac is over-inflated, so that the pressure on the trachea wall is over-high, and when the pressure of the air sac exceeds 30cm H2O, it causes the blood flow disturbance of the tracheal capillary, and the tracheal mucosal tissue may be ischemic and anoxic to cause local inflammation, ulcer, granulation, and even tracheoesophageal fistula. When the pressure of the air bag exceeds 50 cm H2O, blood flow is completely blocked. The trachea inner diameter can not be measured visually, and whether the air sac of the catheter is inflated properly can not be quantified. Generally, the air bag is filled with air by using a syringe, the right finger is separated from a syringe piston (pintle) after the air bag is filled, the syringe piston is pushed back, and when the syringe piston is stopped, the inner pressure of the air bag is balanced with the pressure of the air pipe wall.
If the patient is not inflated enough, about 0.5-l ml should be added, so that the infant is not suitable for intubation. At present, the pressure in the air bag adopts a tentative judgment method, the gas injected into the air bag firstly enables an observation bag at the rear end of the catheter to be slightly full, then the observation bag is connected with a threaded pipe of an anesthesia machine, a volatilization tank switch is opened, volatile general anesthetic (such as sevoflurane) is inhaled, auxiliary breathing or mechanical ventilation is implemented, if smell of the inhalation general anesthetic from the mouth and nose of a patient indicates that the air bag is not sufficiently inflated, the air bag can be gradually inflated for supplement, and the best result is that the smell of the medicine cannot be just smelled.
If an air bag pressure gauge is adopted to manually measure the air bag pressure, air leakage can occur when the air bag indicating ball valve is connected, and research results show that the air bag pressure is reduced by about 2cm H after each measurement2And O. The pressure of the air bag is maintained at 28-30cm H after the air bag is inflated2O, when the incidence of patient microsuction, bacterial concentration of airway secretions, and incidence of VAP were all significantly reduced.
The domestic and foreign investigation results show that most anaesthetists and emergency doctors still adopt the finger touch method experience to judge whether the air bag is inflated enough, which often causes over-inflation, the air bag pressure is even as high as 210mm Hg, and even doctors with abundant experience are not listed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a trachea cannula with standard gasbag can audio-visual observation whether gasbag internal pressure accords with the standard, even the new hand also can use, has improved medical efficiency greatly.
Realize the technical scheme of the utility model is that:
the utility model provides a trachea cannula with standard gasbag, includes exposes gasbag body, gas tube and outlet duct, expose this internal standard gasbag that is equipped with of gasbag, standard gasbag bottom and expose gasbag body coupling, still be equipped with the fixed column on the standard gasbag, the other end of fixed column links to each other with exposing the gasbag body, is equipped with the connecting band on a terminal surface of standard gasbag, and the top of connecting band is equipped with the instruction strip, be equipped with transparent observation window on exposing the gasbag body, transparent observation window arranges in the instruction strip top, is equipped with the standard line on the transparent observation window.
And the inflation tube and the air outlet tube are both provided with one-way valves.
The end face of the standard air bag close to the air outlet pipe is made of soft materials, and the connecting belt is located at one end of the air outlet pipe.
The pressure in the standard air bag is 28-30cm H2O。
The utility model has the advantages that: the utility model is provided with a 28-30cm H gas filled in the exposed air sac of the trachea cannula2The standard airbag of O inflates to exposing inwards during use, the position of the indicating strip arranged on the standard airbag is observed through the observation window, different colors can be arranged in different areas on the indicating strip, the middle area of the indicating strip is normal pressure, when the indicating strip deflects rightwards, the inflation pressure is over-large, when the indicating strip deflects leftwards, the inflation pressure is insufficient, and whether the pressure in the airbag is proper or not can be intuitively observed.
