Description
Technical Field
The utility model relates to a trachea cannula, in particular to a trachea cannula with a bag for suction.
Background
At present, with the popularization of ventilators, especially invasive ventilators, how to manage the airway and avoid the occurrence of ventilator-associated pneumonia (VAP) becomes a focus problem in ventilator applications more and more when invasive ventilators are applied. The occurrence of VAP can lead to prolonged ventilator ventilation and increased mortality of the patient, causing significant physical and economic harm to the patient. Therefore, it is urgent to enhance airway management. The factors that contribute to the occurrence of VAP are numerous, with the resorption of the retentate from the cuff on the endotracheal tube to the lung tissue being an important factor.
For VAP, the prevention is more important than treatment, and clinically, the common tracheal cannula cannot suck back the retentate on the air sac, so that the retentate on the air sac, such as sputum, blood, even gastric contents and the like, easily enters lung tissues, and VAP is caused.
Disclosure of Invention
The utility model aims at solving the problem that the air sac retentate on the tracheal intubation enters the VAP caused by the lung tissue, and providing the tracheal intubation with the air sac for suction.
The utility model provides a take trachea cannula of attraction on bag is that the position of gasbag is provided with the pipe on trachea cannula, and the import of pipe corresponds gasbag bottom setting, goes out the retentate on the gasbag through the pipe drainage.
The guide wires are arranged outside the guide pipe in parallel, and the guide pipe is dragged and supported through the guide wires.
The trachea cannula is provided with a fixed block, the outer side of the fixed block is provided with a clamping groove for fixing the catheter, and the left side and the right side of the fixed block are provided with grooves for winding and fixing the guide wire.
The lower end of the catheter is provided with a connector, and the catheter is connected with an injector through the connector and is used for drainage of retentate on the air bag.
The utility model discloses a use method and theory of use:
through the oral cavity and in the trachea: after exposing a glottis under direct vision by means of a laryngoscope, a catheter is inserted into a trachea through an oral cavity, and the method comprises the following specific steps:
(1) the patient's head is tilted backwards, and the lower jaw is held forward and upward by both hands to open the mouth, or the thumb of the right hand is opposite to the lower dentition and the index finger is opposite to the upper dentition, and the mouth is opened by the rotating force.
(2) And the left hand holds the laryngoscope handle to put the laryngoscope lens into the oral cavity from the right corner of the mouth, and the tongue body is pushed to the side and then slowly pushed, so that the uvula can be seen. The lens is lifted vertically forward until the epiglottis is exposed. The epiglottis is picked up to reveal the glottis.
(3) If a bent lens intubation is adopted, the lens is placed at the junction of the epiglottis and the tongue root (epiglottis valley), and is forcibly lifted forwards and upwards, so that the ligamentum of the hyoid epiglottis is tense, and the epiglottis is tilted to cling to the laryngoscope lens, namely, the glottis is exposed. If a straight lens is used for intubation, the epiglottis is directly lifted, and the glottis can be exposed.
(4) The middle and upper sections of the catheter are held by the thumb, the index finger and the middle finger of the right hand like holding a pen, the catheter enters the oral cavity from the right mouth angle until the catheter approaches the larynx, the pipe end is moved to the laryngoscope lens, the advancing direction of the catheter is monitored through the narrow gap between the lens and the pipe wall through two eyes, and the tip of the catheter is accurately and lightly inserted into the glottis. When the tube core is used for intubation, after the tip end of the guide tube enters the glottis, the tube core is pulled out and then the guide tube is inserted into the trachea. The depth of the catheter inserted into the trachea is 4-5cm, and the distance from the tip of the catheter to the incisors is about 18-22 cm.
(5) After the intubation is finished, the catheter is confirmed to enter the trachea and then fixed. When the trachea cannula is fixed, the catheter is placed at one side of the trachea cannula, and a certain movable gap is reserved.
(6) When the retentate on the air bag needs to be removed, the catheter is detached from the fixed block on the trachea cannula, the connector at the lower end of the catheter is connected through the syringe, and the retentate on the air bag is sucked out at a certain negative pressure. After the operation is finished, the catheter is fixed on the tracheal cannula again.
(7) When the catheter is blocked or the retentate on the air sac is overlarge, a thick standby catheter can be placed into the catheter or the guide wire to replace the original catheter, and the task of removing the retentate on the air sac is completed.
The utility model has the advantages that:
the utility model provides a take trachea cannula of attraction on bag adopts the air current impact method to carry out the gasbag on the retentate clear away the cooperation and inhale phlegm art and can effectively clear up patient's air flue secretion, shortens patient's breathing machine live time, reduces lung's complication. By comparison, the incidence of VAP was 36.7% in patients with the on-balloon retentate clearance test group and 56.7% in patients without the control group. The mean time to live ICU of the patients in the test group is shortened by 3.53 days compared with that in the control group, and the using time of the breathing machine of the patients in the two groups is as follows: the using time of the breathing machine of the patient is shortened by the test group (7.4O +/-2.34) days and the control group (10.93 +/-3.12) days.
Subglottic secretion Aspiration (ASS) was performed by clinical application on patients requiring mechanical ventilation for 48 hours. And the influence of the patients on the conventional application of ASS after all cardiac operations was evaluated, and the incidence rate of Ventilator Acquired Pneumonia (VAP) before and after the application of ASS, the number of mechanical ventilation days and the cost of antibacterial drugs were compared. Pre-and post-intervention results (every 1000 days) were VAP incidence, 23.92vs 16.46(P ═ 0.04); cost of antibiotics: 563, 934 yuan renowned folk ratio 501, 223 yuan renowned folk (P ═ 0.002); mechanical ventilation days were 507.5 days and 377.5 days (P ═ 0.009), respectively. Further, it is suggested that all patients undergoing major cardiac surgery should receive ASS routinely from the moment of anesthesia induction.
Clinical research shows that the retention on the air bag is cleared away for the patient who is assisted to ventilate by the tracheal intubation respirator, so that the occurrence of the pneumonia related to the respirator and the service time of the respirator can be obviously reduced, and the hospitalization cost of the patient is greatly reduced.
