Description
Technical Field
The utility model relates to a medical care equipment field especially relates to an air flue examination blocking up ware with adjustable safe type.
Background
Tracheotomy is an important emergency treatment technology adopted for clinical treatment and rescue of respiratory tract obstruction of critically ill patients caused by various reasons, opens an air passage, is favorable for ventilation and oxygen supply, and has extremely important effects on saving the life of the patients, improving the prognosis and the life quality of the patients and obtaining the success of the rescue of the critically ill patients. After the trachea is cut, the ventilation way of a patient is changed, an artificial airway is established, air directly exchanges through the tracheotomy opening, the patient loses the effects of heating, humidifying and blocking dust and the like of the nose on the air, the airway intangibly loses huge water, the infection rate is increased, and complications are obviously increased. After a patient is out of a critical period and the airway obstruction is relieved or the pulmonary infection is well controlled, doctors usually consider to pull out the tracheal cannula, close the artificial airway and reduce clinical complications. However, many patients are used to artificial airways, and after the tracheal cannula is closed, the ventilation volume through the mouth and the nose is insufficient and cannot tolerate the situation, the patients are chest stuffiness and short breath, the heart rate is accelerated, the blood oxygen saturation is reduced, and even suffocation is caused, so before the tracheal cannula is pulled out, medical personnel usually need to gradually try to block the tracheal cannula, and the gradual transition is performed from the block 1/3 tracheotomy to the semi-blocked tube to the full-blocked tube. After the pipe is blocked, the patient is encouraged to go upstairs and downstairs without urgency, and the vital signs are stable and are successful in pipe blocking. The purpose of the blockage test is to observe whether the patient can stop the direct ventilation of the airway, safely and smoothly transit to normal mouth and nose breathing, and finally seal the tracheotomy opening. In the process of trying to block the tube, close observation is usually needed for 24-72h, and the tube can be pulled out when the patient is stable in breathing, and has no symptoms of chest distress, suffocation and cough and fever. The trial blockage of the airway opening is an important link for helping the patient reestablish the upper respiratory tract passage in the tracheotomy patient care.
At present, no standard instrument for detecting the blockage of the tracheotomy tube exists clinically. Clinical medical care professional magazines report that most medical personnel also adopt self-made cork, rubber stopper, cotton fiber heads and utilize sterile ampoules, stomach tube caps and the like as the trachea incision casing tube blockage testing instruments. However, the cork stopper or rubber stopper is relatively complex to manufacture by itself, and wastes time and labor; the cotton fiber head is easy to generate cotton fiber to stimulate the respiratory tract to cause the patient to choke. The above substitute articles are dangerous to fall into the trachea, are neither standard nor can meet the aseptic requirement, and can not accurately adjust the size of the trial plugging tube area according to the requirement, thereby being not beneficial to improving the working efficiency of medical care and having the potential risk of error accidents of the medical care. Medical personnel often have to diligently confront care methods, care devices that affect patient comfort and safety, and are not comfortable. Therefore, there is a great need for improved tracheostomy tube plugging methods and instruments. The patent application number for CN201220293943.4 provides "a trachea opens adjustable cap stopper of sleeve pipe examination stifled", can be according to clinical demand, the size of the stifled pipe area of regulation examination of standard accurate, the effectual medical care work efficiency that has improved, but it is the same with the stifled device of present majority open sleeve pipe examination, the trachea opens the adjustable cap stopper of sleeve pipe examination stifled external placement and opens the sleeve pipe, drop easily during the use, the air flue bore adjustment is inflexible, can not adjust in real time according to patient's needs, external cap stopper is when patient's activity, the lower jaw touches easily, patient's travelling comfort has been influenced greatly, it is also not enough pleasing to the eye.
SUMMERY OF THE UTILITY MODEL
To above problem, the utility model provides an air flue examination blocking up ware with adjustable safe type embeds in cutting the cover pipe, and patient's lower jaw can not touch, and the travelling comfort is good, can adjust the air vent size, convenient and practical according to patient's volume of ventilating simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an air flue examination blocking device with adjustable safe type, includes can nestification inner tube in the air flue cover and fixes annular regulation stopper in the inner tube, the centre of adjusting the stopper forms airflow channel, adjust the hollow structure of stopper for can changing the volume, through aerifing or disappointing the regulation stopper can adjust airflow channel's size.
The utility model discloses an adjust the stopper and fix including intraductal, then with inner tube nestification in the trachea cover, the outside does not have the protrusion basically, patient when rotating the neck, the lower jaw can not touch, has improved patient's travelling comfort greatly. Meanwhile, the inside of the adjusting plug of the utility model is of a hollow structure similar to a balloon, the whole adjusting plug is of a circular ring shape, the size of the airflow channel can be controlled by changing the volume of the adjusting plug through inflation and deflation, and during inflation, the outer wall of the adjusting plug is fixed on the inner tube, so that the inner diameter of the adjusting plug is continuously reduced along with the increase of the volume, and the airflow channel is reduced; on the contrary, when air is leaked, the airflow channel is enlarged, and the purpose of plugging test is further achieved. The utility model thoroughly changes the external sleeve pipe plugging method which is commonly used clinically, and reduces the risk of falling off of the pipe plugging device and failure of pipe plugging; meanwhile, the buckle parallel to the tracheal cannula effectively ensures the safety of the patient, and the risk that the tube blockage accidentally falls off and enters the airway is eliminated; the whole tube blocking device is small and exquisite in structure, the head part of the tube blocking device is flush with the tracheal cannula, and the lower jaw of a patient cannot touch when the patient lowers the head to move, so that the skin of the lower jaw is protected, and the comfort level of the patient is guaranteed; the size of the air vent of the air hole can be freely adjusted by built-in adjustment, the air volume is properly adjusted according to the actual needs of a patient, the patient is better promoted to tolerate the air volume of the gradually reduced air channel, the aim of completely blocking the tube is achieved more quickly, the success rate of successfully pulling out the tracheal cannula in clinic is increased, and the patient is promoted to recover quickly.
Preferably, the surface of adjusting the stopper is equipped with and to aerify and extract closed inflation hole promptly with the cylinder, and the cylinder is the visible medical equipment of hospital everywhere, makes things convenient for medical personnel to take at any time, and often has the volume sign on the cylinder, makes things convenient for medical personnel to control the volume of aerifing, and then controls the size of air current passageway, and simultaneously, the sheathed tube examination of air flue is stifled mouthful often less, aerifys with the cylinder and can make things convenient for medical personnel to operate.
