Description

Technical Field

[0001] This invention belongs to the field of human trauma model technology, specifically relating to a human model structure for simulating collision trauma. Background Technology

[0002] In daily life and work, especially during sports, traffic accidents, or earthquakes, the human body is prone to impact injuries. For rapid treatment, medical personnel need to quickly assess the severity of injuries and provide accurate care. To improve medical personnel's injury recognition abilities, simulation training devices are needed for practice.

[0003] CN201220260375.8 discloses a trauma hemostasis simulation training mold. The simulated human body model is equipped with an arterial pulsation system, a pressure control system, a fluid circulation system, and a controller pressure control box, providing realistic simulation of arterial and venous bleeding, capable of simulating bleeding under different degrees of injury. However, in actual collisions, there are not only bleeding injuries, but also situations where the bleeding location is relatively hidden or there is internal bleeding. For inexperienced personnel, the aforementioned training mold is difficult to accurately locate the bleeding site and accurately identify the degree of injury. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art, and the purpose of the present invention is to provide a human body model structure for simulating collision trauma.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a human body model structure for simulating collision injuries, comprising a human body model and a controller disposed within the human body model, wherein a fluid circulation system for simulating the human blood system is also installed within the human body model; the human body model is divided into several partitions, each partition having a built-in pressure sensor connected to the controller and a humidity sensor for detecting fluid leakage, each partition having a temperature sensor connected to the controller on its surface, and each partition also having an alarm connected to the controller; when the human body model is injured by a collision, the controller acquires the pressure signal from the pressure sensor and records the impacted partition, the controller acquires the humidity signal from the humidity sensor and records the bleeding partition, the controller acquires the touch partition of the human body model by medical personnel based on the temperature signal from the temperature sensor, and when the touch partition matches the impacted partition and the bleeding partition, the alarm issues a first alarm message.

[0006] The above technical solution divides the human body model into several zones for easy differentiation. Pressure sensors detect the pressure information of the impacted zones, and humidity sensors detect the exposed liquid and its concentration caused by the impact (i.e., detecting whether there is bleeding and the amount of bleeding). When medical personnel touch the human body model for injury assessment, temperature sensors detect a temperature increase. The controller uses the temperature information detected by the temperature sensors to confirm the zone touched by the medical personnel. When the touched zone matches the impacted zone and the bleeding zone, the controller activates the alarm to issue the first alarm message, indicating that the medical personnel have found the impacted zone and the bleeding zone, thus accurately locating the bleeding location. Medical personnel can then accurately locate all bleeding locations by performing a full-body injury assessment, which is beneficial for training medical personnel.

[0007] In a preferred embodiment of the present invention, the human body model is divided into sections including the head, torso, and limbs, with the torso further divided into six sections: upper left, upper right, middle left, middle right, lower left, and lower right.

[0008] In the above technical solution, the human body model's partitions are consistent with those of the human body.

[0009] In a preferred embodiment of the present invention, the human body model includes a deformable support frame and a silicone material of a certain thickness disposed on the surface of the support frame. A liquid circulation system is disposed between the support frame and the silicone material. The controller acquires pressure information from the pressure sensor. When the pressure exceeds the threshold and medical personnel touch the partition, the alarm of the partition issues a second alarm message.

[0010] The above technical solution uses a support frame to simulate the human skeleton and silicone to simulate soft tissues such as muscles, fat, and skin. When the pressure exceeds a threshold, it indicates that the support frame of the impacted area has deformed, alerting medical staff that a fracture has occurred in that area, making it easier for medical staff to accurately identify the degree of trauma and locate the fracture.

[0011] In a preferred embodiment of the present invention, an internal organ model is provided inside the human body model, and an acceleration sensor is provided inside the internal organ model. The controller obtains the information from the acceleration sensor and determines the pressure information of the corresponding partition. When both the acceleration and pressure exceed the threshold and medical staff touch the partition, the alarm of the partition issues a third alarm message.

[0012] In the above technical solution, when both acceleration and pressure exceed the threshold, it indicates that the collision has damaged the internal organs of the human model. When medical staff touch the area, the alarm in that area will issue a third alarm message to remind the medical staff that the internal organs are damaged, so that the medical staff can accurately identify the degree of injury.

[0013] In a preferred embodiment of the present invention, a volume detection device is provided on the internal organ model. The controller obtains the information of the volume detection device and determines the pressure information of the corresponding partition. When the volume change and pressure both exceed the threshold and medical staff touch the partition, the alarm of the partition issues a fourth alarm message.

[0014] In the above technical solution, when both the volume change and pressure exceed the threshold, it indicates that the internal organs are being compressed. When medical staff touch this area, the alarm in that area will issue a fourth alarm message to remind the medical staff that the internal organs have been compressed and deformed, which helps the medical staff to accurately identify the degree of injury.

[0015] In another preferred embodiment of the present invention, the volume detection device includes at least two vertical image acquisition devices disposed on the side of the visceral organ model and whose irradiation area covers the corresponding visceral organ model. The image acquisition devices acquire image sequences of the visceral organs within a certain time before and after the collision occurs; extract the largest and smallest images from the image sequences of the two image acquisition devices; acquire the image area change of the two image acquisition devices, the image area change being the area of ​​the largest image minus the area of ​​the smallest image in the image sequence; select the larger of the two image area changes; acquire the organ size in the vertical direction of the image sequence containing the larger one, the organ size being the maximum length of the organ in that direction when there is no collision; and multiply the larger of the image area changes by the organ size in the vertical direction of the image sequence containing the larger one to obtain the volume change.

[0016] The above-mentioned technical solution can quickly determine the volume changes of internal organs caused by collision and accurately identify the degree of damage to internal organs, especially collision contusions and lacerations.

[0017] In another preferred embodiment of the invention, the alarm is capable of emitting sound and / or light. When the alarm is capable of emitting light, it has LED lights, and the LED lights in each zone are capable of operating independently.

[0018] The above-mentioned technical solution can issue different alarm messages according to the injury situation, making it easier for medical staff to identify the injury situation.

[0019] In another preferred embodiment of the invention, the LED lights in each zone can change color independently.

[0020] The above technical solution allows users to set the color of the LED lights in each zone according to the actual situation.

[0021] In another preferred embodiment of the invention, the LED lights in each zone are of different colors.

[0022] The above technical solution uses different alarm colors for each zone to help medical staff identify the location.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "vertical", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0031] This invention provides a human body model structure for simulating collision trauma, such as... Figure 1 As shown, in a preferred embodiment, the human body model structure includes a human body model 10 and a controller 20 disposed within the human body model 10. For example, the controller 20 is installed in the head 11 of the human body model 10. The human body model 10 is also equipped with a liquid circulation system (not shown in the figure) for simulating the human blood system. The specific liquid circulation system can adopt existing technology, such as the liquid circulation system disclosed in CN201220260375.8.

[0032] The human body model 10 is divided into several sections, specifically including a head 11, a torso 12, and limbs (two arms and two legs). The torso 12 is further divided into six sections: upper left, upper right, middle left, middle right, lower left, and lower right. The arms include upper arms 13 and forearms 14, and the legs include thighs 15 and calves 16. Each section has a built-in pressure sensor 21 connected to the controller 20 and a humidity sensor 22 for detecting liquid leakage. Each section's surface is equipped with a temperature sensor 23 connected to the controller 20, and each section also has an alarm 24 connected to the controller 20. Depending on the actual situation, each section can be equipped with multiple pressure sensors 21, humidity sensors 22, and temperature sensors 23 to make the simulation results more accurate.

[0033] The alarm 24 is capable of emitting sound and / or light to alert medical personnel to injuries of varying degrees. When the alarm 24 emits light, it has LED lights, each of which can operate independently. Preferably, each LED light in each zone can change color independently, with each zone displaying a different color.

[0034] When the mannequin 10 is injured in a collision (specifically, the mannequin 10 can be used in a real-world scenario to simulate a collision and cause injury, or a collision injury simulation device can be used to injure the mannequin 10), the controller 20 acquires the pressure signal from the pressure sensor 21 and records the impact zone, and the controller 20 acquires the humidity signal from the humidity sensor 22 and records the bleeding zone. Medical personnel perform a full-body triage on the mannequin 10. When medical personnel touch the mannequin 10, the temperature sensor 23 senses a temperature increase. The controller 20 uses the temperature signal from the temperature sensor 23 to determine the contact zone of the mannequin 10. When the contact zone matches the impact zone and the bleeding zone, the alarm 24 issues a first alarm message (e.g., the alarm emits a color-changing light), indicating that the medical personnel have located the impact zone and the bleeding zone.

[0035] like Figure 2As shown, in another preferred embodiment, the human body model 10 includes a deformable support frame 101 and a silicone 102 of a certain thickness disposed on the surface of the support frame 101. A liquid circulation system is disposed between the support frame 101 and the silicone 102. When the human body model 10 is subjected to a large impact force, and the pressure value of the pressure sensor 21 of the impacted zone exceeds the threshold, it indicates that the support frame 101 of the impacted zone has deformed. When medical personnel touch the zone, the alarm 24 of the zone issues a second alarm message (such as the alarm sounding to indicate the specific fracture location), reminding medical personnel that a fracture has occurred in the zone, which facilitates medical personnel in accurately identifying the degree of trauma and locating the fracture.

[0036] like Figure 1 As shown, in another preferred embodiment, the human body model 10 is provided with an internal organ model 17, which includes internal organs such as the heart, liver, lungs, kidneys, gallbladder, spleen, stomach, and pancreas. An acceleration sensor 25 is provided in the internal organ model 17. The controller 20 obtains the information from the acceleration sensor 25 and determines the pressure information of the corresponding zone. When both the acceleration and pressure exceed the threshold, it indicates that the collision has damaged the internal organs of the human body model. When medical staff touch the zone, the alarm 24 of the zone issues a third alarm message (such as the alarm sounding to indicate that the internal organs are damaged), reminding the medical staff that the internal organs are damaged. The specific location of the internal organ damage can be confirmed according to the six zones of the torso 12 where the alarm 24 that issued the third alarm message is located: upper left, upper right, middle left, middle right, lower left, and lower right.

[0037] like Figure 1 As shown, in another preferred embodiment, a volume detection device 26 is provided on the internal organ model 17. The volume detection device 26 is used to detect the volume change of the internal organs when a collision occurs. The controller 20 obtains the information from the volume detection device 26 and judges the pressure information of the corresponding partition. When both the volume change and the pressure exceed the threshold, it indicates that the internal organs are being compressed. When medical staff touch the partition, the alarm 24 of the partition issues a fourth alarm message (for example, the alarm sounds to indicate that the internal organs are seriously damaged), reminding the medical staff that the internal organs have been compressed and deformed. The specific location of the compressed internal organs can be identified from the six partitions of the torso 12 where the alarm 24 that issues the fourth alarm message is located: upper left, upper right, middle left, middle right, lower left, and lower right.

[0038] Specifically, the volume detection device 26 includes at least two vertical image acquisition devices disposed on the side of the visceral organ model 17 and whose irradiation area covers the corresponding visceral organ model 17. The image acquisition devices acquire image sequences of the visceral organs within a certain time before and after the collision occurs; extract the largest and smallest images from the image sequences of the two image acquisition devices; acquire the image area change of the two image acquisition devices, where the image area change is the area of ​​the largest image minus the area of ​​the smallest image in the image sequence; select the larger of the two image area changes; acquire the organ size in the vertical direction of the image sequence containing the larger one, where the organ size is the maximum length of the organ in that direction when there is no collision; and multiply the larger of the image area changes by the organ size in the vertical direction of the image sequence containing the larger one to obtain the volume change.

[0039] It should be noted that when medical staff conduct a full-body examination, if the alarm 24 only emits a color-changing light, it indicates that the human model 10 only has bleeding. When the alarm 24 emits a color-changing light and sound prompt, it indicates that in addition to bleeding, the human model 10 also has fractures, internal organ damage, etc. Therefore, the degree of injury can be quickly identified based on the alarm information emitted by the alarm 24.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
