Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to a method and equipment for monitoring, adjusting and maintaining the air bag pressure of an artificial airway.
Background
The artificial airway is an effective means for ensuring the smoothness of the airway and plays an extremely important role in the inside and outside of an operating room. For most patients, the main purpose of establishing an artificial airway is to perform mechanical ventilation, so that most surgical operations in an operating room use an endotracheal tube technology to place an endotracheal tube into the trachea for performing mechanical control breathing, and the patient suffers from serious system diseases outside the operating room such as an intensive care unit and needs to be placed into the artificial airway for performing mechanical ventilation.
However, the establishment of an artificial airway can also damage and destroy normal physiological anatomic functions of the body to some extent, which can cause harm to the patient. In an operating room, after an artificial airway is established, particularly after the trachea cannula is inserted, if the pressure of an air bag (also called a cuff) is too low, air blown by a breathing machine can escape from gaps between the loosened air bag and the trachea to influence the mechanical ventilation effect, and oropharynx secretion and gastric contents can also flow back into the trachea; the air sac is excessively high in pressure, and even if the high-capacity low-pressure air sac is adopted at present, if the air sac is placed for too long, risks such as damage to respiratory tract mucous membrane, tracheoesophageal fistula, tracheal stenosis after tube drawing and the like still can be brought. Outside the operating room, after the tracheal catheter is placed, the patient is restricted in swallowing, oral secretion and gastroesophageal reflux are blocked by the air sac and stay above the air sac, so that the air sac can form a stay above the air sac, and the air sac can flow into the lung when the air sac is under pressure. The research results at home and abroad show that the retentate on the air sac is an important source of the pathogen of the ventilator-associated pneumonia (ventilator associated pneumonia, VAP). Based on the above considerations, air bag pressure monitoring is required.
In the prior art, the more commonly adopted methods for measuring the air bag pressure are as follows:
1. finger touch method: currently, various artificial airways (such as an endotracheal tube, a laryngeal mask airway tube, a tracheostomy tube (tracheostomy tube)) mainly comprise a catheter, an air bag, an inflatable tube, an indicating balloon and a one-way sealing valve, and after the artificial airways are placed in, the indicating balloon exposed out of the airways of a patient can be used for estimating and adjusting the appropriate pressure (25-30 cm H2O) of the air bag in the trachea. The investigation results at home and abroad show that most anesthesiologists and emergency doctors still adopt a finger touch method to judge whether the inflation of the air bag is enough according to the experience of indicating the hardness of the air bag, which often leads to the occurrence of over inflation, and the air bag pressure is even up to 210mmHg (1 mmHg=0.133 kPa), even the doctors with abundant experience are not exceptional. Management expert consensus in combination with artificial airway airbags: recommendation 2. Air bags cannot be inflated using the empirically determined finger touch method, (recommendation level: class C), and therefore, it is not preferable to inflate using the empirically determined finger touch method. And, the external interface of instruction sacculus is mostly smooth straight section of thick bamboo type interface, and this interface can be connected with the syringe, and the syringe is connected the back and is pushed and pushed away the check valve in the instruction sacculus through bulldozing, realizes gasbag, gas tube, instruction sacculus and syringe intercommunication to inject gas and take out gas in the gasbag, and such instruction sacculus interface because it bulldozes the check valve to need external force, so can only satisfy intermittent gasbag pressure measurement or regulation demand, can't realize continuous instruction sacculus pressure measurement or regulation demand.
2. Auscultation method: the method is temporarily adopted under the condition that the pressure of the air bag cannot be measured, and according to the principle that the air bag is inflated to prevent air leakage, after the tracheal intubation of a patient is connected with the auxiliary ventilation of a breathing machine, when the air bag is not inflated enough to seal the air passage, the stethoscope is placed at the position of the throat of the patient, and the air leakage sound is heard while the air bag is inflated slowly until the air leakage sound cannot be heard. While this technique allows the balloon to close just the airway with minimal inflation, it is often not effective in preventing the retentate on the balloon from entering the lower airway. The results of the study showed that the balloon pressure for most patients was still below the appropriate range, although the minimum closure technique was used. The method is complex in operation and low in efficiency.
3. Pressure measurement by an air sac pressure meter: the structure disclosed by the artificial airway catheter adopting the Chinese patent publication No. CN217409507U and the name of visible air bag pressure comprises a catheter body, an air bag inflation mechanism, an inflation tube, a pressure measuring air bag, a one-way valve and an air pressure meter, wherein the air pressure in the air bag body is monitored by the air pressure meter. The adoption of the structure has reliable and accurate pressure measurement and simple operation, but can only intermittently monitor the air bag pressure by people, and can easily cause air leakage of the air bag body when the air bag pressure is adjusted by deflating the one-way valve.
