1. This product is composed of a catheter model and a control box, which can simulate a variety of difficult airway scenarios. Through the high-precision sensors built in the model, it can monitor and feedback the pressure degree of the incisors and the insertion position of the catheter.
2. The model is of moderate size, light weight and suitable for a variety of scenarios. Length ≤ 61cm, width ≤ 28cm, height ≤ 25cm and weight ≤ 4.65kg.
3. The model is an adult male upper body, from the top of the skull to the pylorus; the anatomical position is standard, the texture is soft, and the touch is real.
4. The model is placed in the supine position, equipped with an operating fixing plate, and the intubation process is stable without sliding, which truly simulates the intubation scene of anesthetic patients.
5.  The model head and neck can rotate left and right, supporting the techniques such as lifting the chin, lifting the neck, and lifting the jaw with both hands to open the airway, so that the mouth, pharynx and trachea are basically in the same line.
6. It has a delicate airway structure, and the simulated teeth, tongue, uvula, epiglottis, pharynx, epiglottis, glottis, arytenoid cartilage, thyroid cartilage, airway, bilateral simulated lungs, stomach and other structures are visible.
7. Clinical real oropharyngeal ventilation tube, nasopharyngeal ventilation tube, laryngeal mask ventilation tube, tracheal intubation, endotracheal catheter or bronchial catheter can be used.
8. Support the training and teaching demonstration of orotracheal intubation and nasal intubation under normal conditions and difficult airway conditions.
9. It can be used to remove airway obstruction and attract liquid foreign bodies.
10. The model thorax is designed with visualization to teach the structure of both lungs.
11. The model has esophagus and simulated stomach bag, which supports the demonstration teaching of nasogastric feeding and gastric lavage operation.
12. Correctly insert the airway, and ventilation shows bilateral lung expansion. If the intubation is too deep, when it reaches the left lung, the left lung expands; when it reaches the right lung, the right lung expands. Incorrect insertion into the esophagus, ventilation shows gastric distension.
13. The model adopts infrared photoelectric sensing technology, which can monitor the position of intubation in real time and correctly insert the trachea for voice prompt.
14. The model has a high pressure sensing structure, which can sense the degree of tooth pressure in real time and standardize the operation of tracheal intubation. After the tooth is pressed, voice prompt is given to avoid the risk of tooth damage, loss or even aspiration caused by violent intubation.
15. The model forehead has a life indicator light, which is always on when the intubation enters the airway and the depth is correct.
16. Simulate bilateral carotid artery pulsation, squeeze the hand to simulate carotid artery pulsation.
17. Pupils: one dilated one normal
18. Control box:
18.1 The control is small and light, easy to operate, with ≤ 5 keys, length ≤ 18.5cm, width ≤ 13cm and height ≤ 6cm.
18.2 It has a power indicator light, which lights up when the device is turned on and goes out when the device is turned off; it automatically goes out after power failure or adapter disconnection.
18.3 Monitor and remind the tracheal intubation operation throughout: the correct intubation is performed, the control box voice prompts : insert into the airway, the model headlight is on, and both lungs are expanded after ventilation;
18.4 It can simulate a variety of difficult airway scenarios:
(1) Tongue edema simulation:
After pressing the tongue edema button, the tongue edema indicator light will be on, and the model will immediately display the visual effect of tongue swelling. The trainee can see the swollen tongue and perform intubation training under the tongue edema scenario.
(2) Laryngospasm simulation:
After pressing the laryngospasm button, the laryngospasm indicator light will be on, and the model will simulate the contraction of the larynx muscles, resulting in airway narrowing, and intubation training can be carried out under the laryngospasm scenario.
(3) Tongue edema combined with laryngospasm:
After pressing the tongue edema; and laryngospasm buttons, the tongue edema and laryngospasm indicators will be on, and the model will simulate the situation of tongue swelling and laryngeal muscle contraction, resulting in airway narrowing. The intubation training can be carried out under this situation.
19. It has the function of calibration, which can effectively reduce the problems such as induction error and induction retardation caused by multiple uses. It is simple to operate and quick to calibrate.
