Description

Technical Field

[0001] The utility model relates to the field of simulated dummies, in particular to a simulated dummy for wading rescue. Background Art

[0002] In the field of emergency rescue training, rescue dummies are tools that simulate real drowning people, and their performance is crucial to improving the training effect of rescuers. However, the rescue dummies currently on the market still have some significant limitations when simulating real rescue scenarios, mainly in the following two aspects:

[0003] 1. In the prior art, rescue dummies are usually designed to float on the water. This fixed posture cannot simulate the various states that a drowning person may be in during a real rescue, such as floating on the water, hovering in the water, or sinking to the bottom of the water. These different states will directly affect the difficulty and strategy of the rescue operation. For example, when a drowning person is suspended in the water, rescuers need to quickly judge and take corresponding rescue measures, such as using life buoys or diving rescue. However, since existing rescue dummies cannot simulate this state, it is difficult for rescuers to become familiar with and master the corresponding rescue skills during training.

[0004] 2. The mass of existing rescue dummies is usually fixed and cannot be adjusted according to the weight changes of real drowning people. In actual rescue, the weight of drowning people may vary due to factors such as age, gender, body shape and clothing, which will have an important impact on rescue operations. For example, when rescuing a heavier drowning person, rescuers need greater strength and skills to ensure their safety. However, due to the fixed mass of existing rescue dummies, rescuers cannot fully experience this weight change in training, which may lead to misjudgment or improper operation in actual rescue.

[0005] In summary, the existing rescue dummies have limitations in state adjustment and mass simulation, which limits their training effect in simulating real rescue scenarios. In order to overcome these limitations, it is urgent to propose a wading rescue simulation dummy to solve the problems existing in the prior art. Summary of the invention

[0006] In order to solve the above problems, the utility model provides a wading rescue simulation dummy. Separate inflatable air bags are arranged in the trunk, upper limbs and lower limbs, which are connected to the inflatable nozzle located at the waist of the trunk through separate ventilation pipes, so that rescuers can adjust the sinking and floating state of the dummy as needed to simulate different rescue scenes. The counterweight slots arranged in the head, trunk, upper limbs and lower limbs allow rescuers to add or reduce counterweight blocks according to training needs, further adjust the weight and center of gravity distribution of the dummy, simulate drowning people of different body shapes and weights, and make the training closer to reality.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a wading rescue simulation dummy, including a simulated human body, the simulated human body is composed of a head, a torso, upper limbs and lower limbs, the head is connected to the torso through the neck; wherein the torso, upper limbs and lower limbs are each provided with a separate inflatable airbag; wherein each separate inflation is connected to the inflation nozzle located at the waist of the torso through a separate ventilation pipe; and the head, torso, upper limbs and lower limbs are each provided with a counterweight slot for placing a counterweight block.

[0008] Furthermore, the lower limbs include two legs, and an inflatable airbag is built into the calf position and thigh position corresponding to each leg.

[0009] Furthermore, the torso has a thoracic cavity and an abdominal cavity, a pressing device is provided in the thoracic cavity, and two simulated lungs are provided in the pressing device, and the two simulated lungs are connected to the oral cavity and the nasal cavity on the head through a simulated trachea; a stomach bag is provided in the abdominal cavity, and the oral cavity is connected to the stomach bag through an esophagus and a one-way valve.

[0010] Furthermore, the simulated trachea is divided into a simulated tracheal trunk, a simulated tracheal oral branch and a simulated tracheal nasal branch. The tail end of the simulated tracheal trunk is bifurcated and connected to two simulated lungs, the simulated tracheal nasal branch is connected to the nasal cavity, and the simulated tracheal oral branch is connected to the oral cavity.

[0011] Furthermore, the oral cavity is provided with a detachable simulated lip module.

[0012] Furthermore, the upper limbs of the simulated human body are movably connected to the torso.

[0013] Further, a pressing device is also installed in the chest cavity, wherein two simulated lungs are mounted in the pressing device. Further, the pressing device is divided into an upper box plate and a lower box plate, and the upper box plate and the lower box plate are connected by one or more springs.

[0014] The beneficial effect of the utility model is that the simulated human body is composed of a head, a trunk, upper limbs and lower limbs, and is connected by a neck, which highly restores the structure of a real human body and provides a realistic training environment for rescuers. The separate inflatable air bags arranged in the trunk, upper limbs and lower limbs are connected to the inflation nozzle located at the waist of the trunk through a separate ventilation tube, so that rescuers can adjust the floating state of the dummy as needed to simulate different rescue scenes. By adjusting the inflation volume of the air bag, the simulated dummy can simulate three states of floating on the water surface, hovering in the water, and sinking in the water, so that rescuers can learn the treatment methods for different situations during training and improve rescue skills and coping capabilities. The counterweight slots arranged in the head, trunk, upper limbs and lower limbs allow rescuers to add or reduce counterweight blocks according to training needs, further adjust the weight and center of gravity distribution of the dummy, simulate drowning people of different body shapes and weights, and make the training closer to reality.

DETAILED DESCRIPTION

[0021] See also Figure 1-5As shown, the utility model relates to a wading rescue simulation dummy, including a simulated human body (the surface of the simulated human body is covered with simulated skin in the factory state), the simulated human body consists of a head 1, a torso 2, upper limbs 3 and lower limbs 4, the head 1 is connected to the torso 2 through a neck 13; wherein the torso 2, upper limbs 3 and lower limbs 4 are each provided with a separate inflatable airbag 9; wherein each separate inflatable airbag 9 is connected to an inflation nozzle 10 located at the waist of the torso 2 through a separate ventilation pipe; and wherein the head 1, torso 2, upper limbs 3 and lower limbs 4 are each provided with a counterweight slot for placing a counterweight block 14.

[0022] See also Figure 1-5 As shown, the simulated human body is composed of a head 1, a torso 2, upper limbs 3 and lower limbs 4, and they are connected by a neck 12, which highly restores the structure of a real human body and provides a realistic training environment for rescuers. The separate inflatable air bags 9 arranged in the torso 2, upper limbs 3 and lower limbs 4 are connected to the inflation nozzle 10 (only a one-way valve, an existing tire inflation nozzle 10 similar to that can be used) located at the waist of the torso 2 through a separate ventilation tube, so that rescuers can adjust the sinking and floating state of the dummy as needed to simulate different rescue scenarios. By adjusting the inflation volume of each inflatable air bag 9, the simulated dummy can simulate three states of floating on the water surface, hovering in the water, and sinking into the water, so that rescuers can learn how to deal with different situations during training and improve their rescue skills and coping capabilities. The counterweight slots (see Figure 3 In this specific embodiment, each counterweight slot is set on the back of the simulated human body, and then the corresponding slot is provided with an adaptive counterweight block 14), allowing rescuers to add or reduce the counterweight block 14 according to training requirements, further adjust the weight and center of gravity distribution of the dummy, simulate drowning people of different body shapes and weights, and make the training closer to reality.

[0023] In the design of the simulation dummy, in order to simulate the three states of floating on the water surface, hovering in the water, and sinking in the water, the following comprehensive solutions can be adopted:

[0024] The buoyancy adjustment system and the weight adjustment system are integrated inside the simulation dummy. The buoyancy adjustment system is realized by the inflatable airbag 9, which is manually operated by the inflatable air nozzle 10 to adjust the gas volume of the inflatable airbag 9, thereby controlling the buoyancy of the simulation dummy. When the inflatable airbag 9 is fully filled with gas, the simulation dummy will float on the water.

[0025] At the same time, the simulation dummy is also provided with an adjustable counterweight 14, such as a movable lead block. Different counterweights 14 in different counterweight slots can be adjusted manually to change the overall density of the simulation dummy. By precisely controlling the buoyancy of the counterweight and the airbag, the simulation dummy can be made to hover at a specific depth in the water.

[0026] When the simulated dummy needs to sink to the bottom of the water, it can be achieved by increasing the density of the simulated dummy. This can be achieved by filling a counterweight 14, such as lead or iron, inside the simulated dummy. In addition, the airbag can be manually operated to release gas to further reduce the buoyancy and make the simulated dummy sink to the bottom of the water.

[0027] See also Figure 1-2 As shown, further, the lower limb 4 includes two legs, and an inflatable airbag 9 is built into the calf 42 position and the thigh 41 position corresponding to each leg.

[0028] By having inflatable airbags 9 built in the calf 42 and thigh 41 of each leg, rescuers can more finely adjust the sinking and floating state of the lower limbs 4 of the simulated dummy. This design makes the simulated dummy's posture in the water more diverse and can simulate a more realistic rescue scene. By independently controlling the inflation volume of the airbags in the calf 42 and thigh 41, different postures of the drowning person can be simulated, such as leg sinking, bending or stretching. These postures may correspond to different rescue situations, such as leg injuries or spasms of the drowning person. Rescuers can train for these specific situations to improve their coping capabilities.

[0029] Since the floating and sinking state of the lower limb 4 can be adjusted independently, rescuers can simulate more complex rescue scenarios during training. For example, simulating a drowning person with injured legs and unable to float up on their own, rescuers can be trained on how to drag and rescue more effectively. This training can significantly improve the actual combat capability and reaction speed of rescuers.

[0030] Furthermore, the trunk 2 has a thoracic cavity and an abdominal cavity, a pressing device 6 is provided in the thoracic cavity, and two simulated lungs 5 ​​are provided in the pressing device 6, and the two simulated lungs 5 ​​are connected to the oral cavity on the head 1 and the nasal cavity 11 on the head 1 through a simulated trachea 8; a stomach bag 7 is provided in the abdominal cavity, and the oral cavity is connected to the stomach bag 7 through an esophagus. The pressing device 6 and the simulated lung 5 provided in the thoracic cavity can truly simulate the cardiopulmonary function of the human body in a drowning or coma state. Rescuers can simulate the chest compression process of cardiopulmonary resuscitation by operating the pressing device 6, and observe the response of the simulated lung 5 and the simulated trachea 8 at the same time to evaluate whether the effect and strength of the compression are appropriate. In addition, by connecting the simulated lung 5 with the oral cavity and the nasal cavity 11 of the head 1, rescuers can simulate the process of artificial respiration. This design can help rescuers practice correct artificial respiration techniques, including the frequency, depth and duration of breathing, as well as key operations such as ensuring that the airway is unobstructed.

[0031] Since the oral cavity is connected to the esophagus and the stomach 7, the rescuer can simulate the situation that there is foreign matter or vomitus in the mouth of the drowning person. In the training, the rescuer can learn how to effectively remove foreign matter in the oral cavity and the method of handling the vomitus of the drowning person to ensure that the respiratory tract is unobstructed.

[0032] For example, the stomach bag 7 of the simulated dummy can simulate the situation that a drowning person needs to perform the Heimlich maneuver due to foreign matter blocking the respiratory tract. Rescuers can learn and master the correct operation steps of the Heimlich maneuver by operating the simulated dummy.

[0033] Preparation phase: First, make sure the dummy is in a suitable position, usually standing or sitting. The rescuer stands behind the dummy to perform abdominal impact.

[0034] To perform the Heimlich maneuver:

[0035] The rescuer makes a fist with one hand, with the palm facing inward, and points the thumb side toward the stomach area of ​​the dummy (the simulated abdominal position). The other hand covers the fisted hand to form a stable grip. Quickly and forcefully impact the upper abdomen of the dummy (i.e., the stomach 7 position) inward and upward. This impact should be fast and powerful to simulate the abdominal impact in the Heimlich maneuver. Repeat the impact several times until the dummy "vomits" the foreign object (in the simulated scenario, this may be manifested as a sign or signal). The rescuer can evaluate the accuracy and effectiveness of his or her implementation of the Heimlich maneuver by observing the dummy's reaction (such as the signal of "vomiting" the foreign object).

[0036] See also Figure 5 As shown, further, the simulated trachea 8 is divided into a simulated tracheal trunk 83, a simulated tracheal oral branch 82 and a simulated tracheal nasal branch 81, the tail end of the simulated tracheal trunk 83 is connected to two simulated lungs 5, the simulated tracheal nasal branch 81 is connected to the nasal cavity 11, and the simulated tracheal oral branch 82 is connected to the oral cavity.

[0037] By simulating the design of the tracheal trunk, oral branch and nasal branch, the simulation dummy can simulate the breathing process of the human body more realistically. Rescuers can observe the expansion and contraction of the simulated lung 5 under the operation of the pressing device 6, as well as the process of gas entering and leaving the simulated lung 5 through the simulated tracheal oral branch 82 and the simulated tracheal nasal branch 81, so as to have a deeper understanding of the breathing mechanism. Since the simulated trachea 8 is divided into an oral branch and a nasal branch, rescuers can train the skills of artificial respiration through the oral cavity and the nasal cavity respectively. This design makes the training more comprehensive and can help rescuers master the best breathing assistance method in different situations. Simulating complex rescue scenarios: The multi-channel design of the simulated trachea 8 enables the simulation dummy to simulate more complex rescue scenarios. For example, in the case of a simulated drowning person with both oral and nasal obstructions, rescuers need to quickly remove the obstructions and help the drowning person resume breathing through the correct breathing assistance method. This training can improve the rescuers' ability to respond to emergencies and their ability to handle complex situations.

[0038] Furthermore, the oral cavity is provided with a detachable simulated lip module 12. As a part of the oral cavity, the simulated lip module 12 is often in contact with the rescuer's operations and is easily contaminated. By designing it as a detachable module, the rescuer can easily remove it for cleaning and disinfection to ensure the hygienic condition of the simulated dummy when it is used next time. Extending the service life of the simulated dummy: Since the simulated lip module 12 is detachable, if it is worn or damaged during use, the module can be replaced alone without replacing the entire simulated dummy. This not only reduces maintenance costs, but also extends the service life of the simulated dummy.

[0039] Furthermore, the upper limbs 3 of the simulated human body are movably connected to the trunk 2. Through the movable connection design, the upper limbs 3 of the simulated human body can simulate the range of motion of a real human body, such as bending, stretching, rotation and other movements. This makes the simulated dummy present a more realistic and natural human posture in the water or on the ground, providing rescuers with a training environment that is closer to a real rescue scene. In addition, rescuers need to face various complex rescue scenes during training, including dealing with the upper limbs 3 of drowning people. Through the design of the upper limbs 3 with movable connections, the simulated dummy can simulate different upper limb 3 states, such as stiffness, weakness, twisting, etc., to help rescuers learn how to effectively deal with these situations. This highly targeted training design helps to improve the response ability and practical skills of rescuers.

[0040] See also Figure 4As shown, further, a pressing device 6 is also installed in the chest cavity, wherein two simulated lungs 5 ​​are mounted in the pressing device 6. Further, the pressing device 6 is divided into an upper box plate 61 and a lower box plate 62, and the upper box plate 61 and the lower box plate 62 are connected by a spring 63 (in this specific embodiment, a spring 63 is used). The design of the upper box plate 61 and the lower box plate 62 connected by the spring 63 can simulate the chest pressure bearing capacity of a standard ordinary person. When a pressing force of 50 kg is applied, the chest sinks 5 cm. This data conforms to the physiological reaction of the real human body, so that the rescuer can truly feel the strength and effect of chest compression during training. Accurate control of pressing force and frequency: the pressing device 6 can withstand a pressing force of 50 kg and can withstand a compression frequency of 100-120 times per minute. This design ensures the accuracy and stability of the pressing force and frequency during the training process, helps rescuers master the correct chest compression skills, and can be trained at different frequencies to improve the ability to deal with various emergencies. Since the pressing device 6 can simulate the chest compression reaction of a real human body, rescuers can more intuitively understand the importance and correct operation method of chest compression during training. At the same time, through repeated practice, rescuers can gradually improve their operating skills and coping ability, thereby improving the training effect.
