Description

Technical Field

[0001] The utility model relates to the technical field of first aid training instruments, in particular to a novel training simulator for the "Heimlich maneuver". Background Art

[0002] Airway foreign body obstruction is a sudden and dangerous situation in daily life, often leading to acute respiratory obstruction and seriously threatening life safety. As an effective response method, the popularization of the Heimlich maneuver is of great significance. However, the lack of suitable training simulators currently brings great obstacles to the public's learning of this first aid technique. Some existing Heimlich training devices have many defects. For example, when simulating airway obstruction, they are wrongly connected to the stomach, which seriously misleads the public's understanding of the accurate anatomical structure of the human body and forms wrong concepts during the learning process. There are also some training devices that simply simulate squeezing the abdominal airbag to expel foreign bodies, and the connection between the abdominal airbag and the organ-like structure does not conform to the real anatomical structure of the human body, which may cause learners to develop wrong force-using habits during training and be unable to effectively provide first aid in case of an emergency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel training simulator for the "Heimlich maneuver". By squeezing the rubber body on the upper abdomen above the umbilicus, the intra-abdominal pressure is increased, the simulated diaphragm structure is passively lifted, the thoracic cavity is squeezed, and then the airbag of the simulated lung structure is squeezed so that gas rushes out through the trachea, and the foreign body blocked in the trachea is discharged, thus solving the problem that learners develop wrong force-using habits during training.

[0004] To achieve the above object, the utility model provides the following technical solution: A novel training simulator for the "Heimlich maneuver", characterized in that it includes a simulated thoracic cavity (1) formed by integrating a back plate (14) and a front chest rib plate (15). A rubber body (21) is provided below the front chest rib plate (15). The rubber body (21) and the back plate (14) enclose an abdominal cavity chamber (2) integrally. The back plate (14) and the front chest rib plate (15) are made of hard plastic, and a layer of silicone rubber layer is coated on the outside of the back plate (14) and the front chest rib plate (15). A pair of simulated lung structure airbags (11) are arranged in the thoracic cavity. A silicone simulated diaphragm structure (3) is fixedly arranged below the simulated lung structure airbag (11) in the simulated thoracic cavity (1). A trachea (12) is installed in the middle of the simulated thoracic cavity, and two branch pipes (13) are connected below the trachea and communicated with the left and right simulated lung structure airbags (11) respectively.

[0005] The described silicone human training model includes a silicone human torso, and an abdominal cavity chamber (2) is provided below the position of the simulated thoracic cavity (1) of the silicone human torso. A simulated diaphragm structure (3) is provided between the thoracic cavity chamber and the abdominal cavity chamber.

[0006] The described simulated diaphragm structure (3) is in the shape of a domed roof.

[0007] The interior of the simulated lung structure airbag (11) is a rubber honeycomb structure.

[0008] The described trachea (12) is made of semi-rigid plastic material, is wider at the top and narrower at the bottom, with a length of 9 - 13 cm and a diameter of 15 - 20 mm.

[0009] The left and right sides of the described backboard (14) are respectively equipped with straps (16) for simulation practice.

[0010] On the inner surface of the inner cavity of the described trachea (12), several groups of annular protrusions are fixed at equal distances, and a blocking object is placed in the inner cavity of the trachea (12).

[0011] First, the user uses the straps (16) installed on the left and right sides of the backboard (14) to fix the entire training simulator in front of the body to prepare for simulation practice.

[0012] At the beginning of the simulation practice, if it is necessary to simulate the situation of airway foreign body obstruction, place the blocking object in the inner cavity of the trachea (12). The several groups of annular protrusions fixed at equal distances on the inner surface of the inner cavity of the trachea (12) can well simulate the complex situation of foreign body obstruction in the real airway.

[0013] Next, when performing the simulated operation of the Heimlich maneuver, squeeze the rubber body (21) in the simulated abdominal cavity (2) at the punctuation mark above the umbilicus. Since the simulated abdominal cavity (2) is integrally enclosed by the rubber body (21) and the backboard (14), it has a certain elasticity and toughness and can simulate the force-bearing situation of the real human abdomen.

[0014] When squeezing the rubber body (21), the generated pressure will cause the intra-abdominal pressure to increase. The silicone simulated diaphragm structure (3) located below the simulated lung structure airbag (11) will be lifted passively due to the increase in intra-abdominal pressure, just as the diaphragm is lifted due to the increase in intra-abdominal pressure in the real situation.

[0015] At the same time, the simulated thoracic cavity (1) is squeezed, and the internal simulated lung structure airbag (11) will also be subjected to corresponding pressure. Since the interior of the simulated lung structure airbag (11) is a rubber honeycomb structure, it will produce deformations and pressure changes that conform to the actual situation when being squeezed. Thus, the gas inside the simulated lung structure airbag (11) is discharged from the trachea (12), and the blocking object is discharged.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] Its simulation structure is more in line with the true human anatomical structure, avoiding the misguidance caused by incorrect connection, and enabling learners to establish a correct understanding of the human body.

[0018] By setting components such as a simulated thoracic cavity, lumbar and abdominal regions, diaphragm, and lung structure airbags, as well as a unique trachea and latex tube design, it can comprehensively and realistically simulate the operation process and effect of the Heimlich maneuver.

[0019] The elastic design of the rubber body and the rubber honeycomb structure inside the lung structure airbag make the force reaction and pressure change more realistic, helping learners develop correct force application habits and enabling effective rescue in case of actual emergencies.

[0020] The setting of the shoulder strap (16) increases the convenience and stability of use, facilitating learners to practice at any time and place.

[0021] The annular protrusion in the trachea and the pluggable object can more accurately simulate the complex situation of airway foreign body obstruction, increasing the difficulty and authenticity of training, so that learners can respond more calmly when facing real airway foreign body obstruction.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will comprehensively describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0027] As shown in the figure, a new type of "Heimlich maneuver" training simulator includes a simulated chest cavity 1 formed by integrating a back plate 14 and a front chest rib plate 15. A rubber body is provided below the front chest rib plate 15, and the rubber body 21 and the back plate 14 enclose an abdominal cavity chamber 2 together. The back plate 14 and the front chest rib plate 15 are made of hard plastic, and a layer of silicone rubber layer is coated outside the back plate 14 and the front chest rib plate 15. A pair of lung-like structure air bags 11 are arranged in the chest cavity. A silicone simulated diaphragm structure 3 is fixedly arranged below the lung-like structure air bags 11 in the simulated chest cavity 1. A trachea 12 is installed in the middle of the simulated chest cavity, and two branch pipes 13 are connected below the trachea and are respectively communicated with the left and right lung-like structure air bags 11.

[0028] The silicone human training model includes a silicone human torso, and an abdominal cavity chamber 2 is arranged below the position of the simulated chest cavity 1 of the silicone human torso. A simulated diaphragm structure 3 is arranged between the chest cavity chamber and the abdominal cavity chamber.

[0029] The simulated diaphragm structure 3 is in the shape of a dome.

[0030] The internal part of the lung-like structure air bag 11 is a rubber honeycomb structure.

[0031] The trachea 12 is made of semi-rigid plastic, is thick at the top and narrow at the bottom, with a length of 9 - 13 cm and a diameter of 15 - 20 mm.

[0032] Shoulder straps 16 are respectively installed on the left and right sides of the back plate 14 for simulation practice.

[0033] A number of groups of annular protrusions are fixedly arranged on the inner surface of the inner cavity of the trachea 12 at equal distances, and a blocking object is placed in the inner cavity of the trachea 12.

[0034] First, the user uses the shoulder straps 16 installed on the left and right sides of the back plate 14 to fix the entire training simulator on the front side of the body and get ready for simulation practice.

[0035] At the beginning of the simulation practice, if you want to simulate the situation of airway foreign body obstruction, place the blocking object in the inner cavity of the trachea 12. The number of groups of annular protrusions fixedly arranged on the inner surface of the inner cavity of the trachea 12 at equal distances can well simulate the complex situation of foreign body obstruction in the real airway.

[0036] Then, when performing the simulation operation of the Heimlich maneuver, squeeze the rubber body 21 in the simulated abdominal cavity 2 above the navel. Since the simulated abdominal cavity 2 is formed by enclosing the rubber body and the back plate 14 together, it has a certain elasticity and toughness and can simulate the force condition of the real human abdomen.

[0037] When squeezing the rubber body 21, the generated pressure will cause an increase in intra-abdominal pressure. The silica gel diaphragm-like structure 3 located below the lung-like structure airbag 11 will be lifted passively due to the increase in intra-abdominal pressure, just as the diaphragm is lifted due to the increase in intra-abdominal pressure in real situations.

[0038] At the same time, the simulated thoracic cavity 1 is squeezed, and the lung-like structure airbag 11 inside will also be subjected to corresponding pressure. Since the inside of the lung-like structure airbag 11 is a rubber honeycomb structure, it will produce deformation and pressure changes that conform to the actual situation when being squeezed. Thereby, the gas inside the lung-like structure airbag 11 is discharged from the trachea 12 to discharge the blockage.
