Description

Technical Field:

[0001] The utility model relates to the technical field of infant first aid, in particular to an infant airway foreign body obstruction first aid training model. Background Art:

[0002] The principle of the Heimlich maneuver is to use the airflow generated by impacting the abdomen - the soft tissue under the diaphragm to expel foreign objects blocking the trachea and larynx, thus saving people's lives. For the first aid of infants (under 1 year old), the prior art gives specific operation requirements, namely the five - time back - patting method and the five - time chest - pressing method. In order to enable the students majoring in infant care in our school to quickly master this first - aid skill, our school customized a batch of training models (teaching aids), whose main structure and functions are similar to those of an infant airway foreign body obstruction first - aid training teaching aid (authorization announcement number: CN217181719U) disclosed in a Chinese patent. Through the pressure sensor, it can detect the pressing position and number of times, effectively improving the training level of our school students.

[0003] However, with continuous training applications, the teachers and students in our school found that the functions of this training model are still relatively single and cannot be trained comprehensively. For example, the pressing frequency cannot be effectively trained, which is very important during first aid. In addition, when performing the five - time chest - pressing method, the pressing depth (strength) cannot be effectively trained. If the pressing depth is too large, it will actually cause certain damage to the infant. Therefore, it is necessary to optimize and improve on the basis of the existing training teaching aids in order to further improve the training and enhance the training level.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Content of the Utility Model:

[0005] The purpose of the utility model is to solve the problems existing in the prior art, and provide an infant airway foreign body obstruction first - aid training model, which has the advantages of reasonable structural design, more comprehensive training detection, and is helpful for improving the training level.

[0006] The utility model realizes the above - mentioned purpose by adopting the following technical solutions:

[0007] Infant airway foreign body obstruction first aid training model, including an infant model. The infant model is internally provided with a respiratory system model.

A foreign body model is arranged in the trachea. By pressing the chest of the infant model, the air in the lungs can flow through the bronchi to the trachea and act on the foreign body model. A pressure sensor A is provided at the corresponding back-patting position on the infant model, and a pressure sensor B is provided at the corresponding chest-pressing position on the infant model. A bracket and a pressure sensor C are arranged inside the infant model. The lower end of the bracket is arranged on the inner side of the back of the infant model, and the upper end is provided with the pressure sensor C. The pressure sensor C is located below the chest-pressing position and has a spacing. The pressure sensor A, the pressure sensor B, and the pressure sensor C are respectively connected to a controller. The controller is connected to a timer, and the controller is connected to a display. A power supply is arranged inside the infant model, and the power supply supplies power to the controller, the display, the timer, the pressure sensor A, the pressure sensor B, and the pressure sensor C respectively.

[0008] The foreign body model is connected with a traction line.

[0009] An optoelectronic sensor is arranged at the inlet end of the trachea. The optoelectronic sensor is connected to the controller, and the controller is connected to a voice player.

[0010] Convex columns are provided at the positions corresponding to the mounting brackets on the infant model. Threaded holes are provided on the convex columns. The bracket adopts a triangular bracket, and the triangular bracket is arranged on the convex column through threaded connection. The pressure sensor C is arranged at the upper end of the bracket through threaded connection.

This part belongs to the prior art or can be programmed by a third-party programming company according to the design requirements.

[0029] Instructions for use of the baby airway foreign body obstruction first aid training model of this application:

[0030] First, perform the five-back-patting method:

[0031] Turn on the power switch, place the baby model 1 prone and straddle it on one arm of the rescuer. Support the head and jaw of the baby model 1 with the hand. The head of the baby model 1 is lower than the torso. Tap the back between the two scapulas of the baby model 1 once per second for 5 times. If the voice player 13 does not play the baby's cry, it means that the foreign body model 10 has not been removed, and then the five-chest-compression method needs to be performed. The above operation process is detected by the pressure sensor A3 and the timer 8 and the signals are transmitted to the controller 7.

[0032] Five-chest-compression method:

[0033] Turn the baby model 1 into a supine position, and quickly press the two fingers 5 times at the center directly below the two nipple lines. If the voice player 13 plays the baby's cry, it means that the foreign body model 10 has been removed and the first aid is successful. Otherwise, repeat the above process (set a time limit, for example, set 5 minutes. If the first aid is still not successful within 5 minutes, it means the training fails. Check and analyze the reason for failure through the display and conduct retraining) until the baby's cry is played. The display can show the number of times and the pressure values of the pressure sensor A3, the pressure sensor B4, and the pressure sensor C6 corresponding to the time (which can be reflected by a bar chart. For example, the X-axis is the time axis, the Y-axis is the pressure value, the detection value of the pressure sensor A3 is represented by a thin solid line, the detection value of the pressure sensor B4 is represented by a thick solid line, and the detection value of the pressure sensor C6 is represented by a dotted line).
