Description

Technical Field

[0001] This invention relates to a simulation demonstration device for gastrointestinal decompression in newborns, belonging to the technical field of simulation demonstration devices. Background Technology

[0002] Simulated teaching of neonatal gastrointestinal decompression requires the use of a real nasogastric tube on the main body 2 of the nasogastric tube decompression device to perform tube insertion on a neonatal mannequin. The tube insertion is divided into insertion into the nasal cavity, insertion into the oral cavity, and insertion into the trachea. During the tube insertion process, the neonatal mannequin's head needs to be flexed forward, and it is necessary to ensure that the head does not tilt after flexion. The tube inserted in the neonatal mannequin needs to be viewed in real time through any position of the perspective view, and the insertion length and insertion position should be displayed. In view of the above-mentioned simulated teaching needs, the present invention proposes a simulated demonstration device for neonatal gastrointestinal decompression. Summary of the Invention

[0025] Working principle: (1) Normal intubation: Insert the real nasogastric tube of the nasogastric tube decompression device body 2 into the mannequin a1 until it is inserted into the stomach of the mannequin a1. When it is inserted 3-5cm from the nasal cavity, the mannequin a1 child’s head needs to be lifted and flexed forward by the operation of the head flexion mechanism 4, and the child’s chin is pressed against the sternum to expand the range of the oropharynx.

[0026] (2) Accidental insertion into the oral cavity: When a real nasogastric tube is inserted into the mannequin a1, the child's chin is not pressed against the sternum when it is inserted into the throat of the mannequin a1, and it is accidentally inserted into the oral cavity. The nasogastric tube needs to be removed.

[0027] (3) Accidental insertion into the trachea: When a real nasogastric tube is inserted into the mannequin a1, the child's chin is not pressed against the sternum when it is inserted into the throat of the mannequin a1, and it is accidentally inserted into the trachea. The nasogastric tube is immediately removed when the child coughs.

[0028] During the simulated intubation process described above, the real-time position of the nasogastric tube can be viewed and the insertion length and position can be displayed on the screen of the main display body 5 at any position of the perspective view scanned by the terahertz imaging scanner body 354.

[0029] The practical simulation demonstration of the nasogastric tube decompression device body 2 on mannequin a1 after intubation and the teaching operation of gastrointestinal decompression and drainage will not be described in detail here.

[0030] During the simulation demonstration, mannequin a1 is placed on the simulation bed 1, with its head resting flat on the head flexion and swing mechanism 4. The head flexion and swing mechanism 4 operates to flex the mannequin a1's head forward. First, the extension of the telescopic device 44 pushes the swing seat 41 to the right, causing the mannequin a1's head to flex forward, placing the child's chin against the sternum. When the head shifts left or right on the headrest pad 43, the rotator 421 drives the rotating lower seat 422 to reciprocate. The maximum ±15° rotational fine-tuning is achieved when the head is tilted to one side on the headrest cushion 43. The motor 425 drives the deflection upper seat 424 to swing left and right on each sliding ball 423 with a maximum ±8° tilt adjustment. The tilt is then fine-tuned and corrected. Meanwhile, the locking guide wheel 4226 slides on the second arc frame 4244 to ensure that the deflection upper seat 424 is held in place and does not disengage. This keeps the gear on the motor 425 meshing with the arc rack 4245.

[0031] The terahertz imaging scanner body 354 performs scanning operations on any position of the simulated human a1. First, by pulling the first push-pull handle 34 horizontally to the left and right, the magnetic suction slide 32 slides left and right on the iron slide rail 31, allowing the terahertz imaging scanner body 354 to perform left and right displacement scanning above the simulated human a1. After the magnetic suction slide 32 moves, the magnetic suction wheel 324 forms a magnetic attraction with the side wall of the iron slide rail 31. Under the action of a small external force, the terahertz imaging scanner body 354 will not have a problem of left and right slippage. For the forward and backward sliding of the terahertz imaging scanner body 354, firstly, the electromagnetic chuck 333 disengages from the magnetic suction convex edge 352. Then, by pulling the second push-pull handle 355 back and forth, the telescopic inner tube 351 extends and retracts along the arc inside the outer tube body 331, which is used to scan the front, back, sides and top surface of the simulated human a1. Finally, the position is fixed by the electromagnetic chuck 333 re-electromagnetically adsorbing the magnetic suction convex edge 352.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
