Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a helmet with a detection function. Background Art

[0002] At present, medical staff's assessment of the severity of TBI injuries depends mainly on radiological imaging examinations such as CT, in addition to the subjective self-report, GCS score and vital signs of the injured. However, in actual situations, due to the special environment, large medical equipment such as CT is inconvenient to carry or difficult to quickly arrive at the scene. And mild concussion usually does not lead to organic lesions, so computed tomography (CT) and magnetic resonance imaging (MRI) play a limited role in diagnosis. In general, the current TBI immediate diagnosis and warning lacks objective evaluation standards and portable monitoring technology, which has become the main obstacle to the diagnosis and treatment of mild concussion in clinical practice.

[0003] In recent years, some new medical information analysis, such as neuroimaging and biomarker examinations in body fluids, have provided new ideas for clinical decision-making (such as evacuation and surgery). However, this type of research is still in its infancy, and the sensitivity and specificity have yet to be verified. There is no consensus on the relationship between the range of increase or decrease of various biomarkers and the severity of TBI, and the impact of the sampling time window on the results. In addition, laboratory detection of biomarkers also mostly uses ELISA, which is complex and susceptible to interference. In the case of earthquake rescue and war, where medical resources on the scene are extremely limited, this screening and evaluation method is obviously not suitable for the rapid evaluation and screening of large numbers of casualties.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1 and Figure 2As shown, a helmet with a detection function comprises a helmet body 1, the lower surface of the helmet body 1 is fixedly connected with a matching fixing belt 2, the outer surface of the matching fixing belt 2 is sleeved with a monitoring and early warning main device 3 that is slidably connected, and the two ends of the matching fixing belt 2 are fixedly connected with mutually matching buckles, the monitoring and early warning main device 3 comprises an outer shell 31 that is slidably sleeved on the outer surface of the matching fixing belt 2, the interior of the outer shell 31 is embedded with an inner shell 32 that is slidably connected, the outer surface of the inner shell 32 is sequentially embedded with an embedded switch 33, an acceleration sensor 34 and three indicator lights 35 that are fixedly installed, the interior of the inner shell 32 is sequentially fixedly installed with a power supply module 36 and an acceleration force comparator 37, the three indicator lights 35 are green, yellow and red respectively, when in use, the monitoring and early warning main device 3 is installed on the matching fixing belt 2, and the monitoring and early warning main device 3 is placed behind the neck, and then the monitoring and early warning main device 3 is started by the embedded switch 33, and the power supply module 36 supplies power to the acceleration sensor 34 and the acceleration force comparator 37. The acceleration sensor 34 is electrically connected to the acceleration comparator 37. The acceleration sensor 34 sends the acceleration information of the monitoring and early warning main device 3 to the acceleration comparator 37. When a collision occurs, the acceleration sensor 34 detects the acceleration signal of the amplitude of the head movement of the person during the collision. When the amplitude of the head movement of the person is lower than the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the green indicator light 35 to emit a light, indicating that the brain impact amplitude is still within a controllable range or a mild impact brain injury has been suffered; when the head movement amplitude of the person is 1 to 2 times the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the yellow indicator light 35 to emit a light, indicating that a moderate impact brain injury may have been suffered; when the head movement amplitude of the person is greater than 2 times the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the red indicator light 35 to emit a light, indicating that a severe impact brain injury may have been suffered and life is threatened.

[0025] Embodiment 2:

[0026] A clamping mechanism 38 is installed between the inner shell 32 and the outer shell 31. A USB charging port matching the power module 36 is embedded and fixedly installed on one side of the outer surface of the inner shell 32. A through hole 310 matching the USB charging port is provided on the outer surface of the outer shell 31. The clamping mechanism 38 includes grooves 381 symmetrically provided on both sides of the outer surface of the inner shell 32. A spring 382 is fixedly connected to the inner wall of the groove 381. A clamping block 383 is fixedly connected to one end of the spring 382. A clamping groove 384 matching the clamping block 383 is provided on both sides of the inner wall of the outer shell 31. An arc surface is provided on the lower surface of one end of the clamping block 383. When installing, the inner shell 32 only needs to be pressed toward the inside of the outer shell 31. At this time, the clamping block 383 automatically shrinks under the action of the arc surface. When the clamping block 383 overlaps with the clamping groove 384, the spring 382 automatically drives the clamping block 383 to reset, thereby realizing the installation of the inner shell 32.

[0027] Embodiment 3:

[0028] A pushing mechanism 39 that cooperates with the clamping mechanism 38 is installed inside the shell 31. The pushing mechanism 39 includes a push rod 391 that penetrates the shell 31 and is slidably connected to the shell 31. One end of the push rod 391 extends to the inside of the clamping groove 384 and is fixedly connected to a push plate 392. One end of the push rod 391 located outside the shell 31 is fixedly connected to a pressing plate 393. When disassembling, the clamping block 383 can be pushed out of the clamping groove 384 by pressing the pressing plates 393 on both sides through the push rod 391 and the push plate 392, and then the inner shell 32 can be removed. The operation is simple and convenient for maintenance.

[0029] Working principle: When in use, the monitoring and early warning main device 3 is installed on the matching fixing belt 2, and the monitoring and early warning main device 3 is placed behind the neck, and then the monitoring and early warning main device 3 is started through the embedded switch 33, and the power module 36 supplies power to the acceleration sensor 34 and the acceleration force comparator 37. The acceleration sensor 34 is electrically connected to the acceleration comparator 37. The acceleration sensor 34 sends the acceleration information of the monitoring and early warning main device 3 to the acceleration comparator 37. When a collision occurs, the acceleration sensor 34 detects the acceleration signal of the amplitude of the head movement of the person during the collision. When the amplitude of the head movement of the person is lower than the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the green indicator light 35 to emit a light, indicating that the brain impact amplitude is still within a controllable range or a mild impact brain injury has been suffered; when the head movement amplitude of the person is 1 to 2 times the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the yellow indicator light 35 to emit a light, indicating that a moderate impact brain injury may have been suffered; when the head movement amplitude of the person is greater than 2 times the preset value of the acceleration comparator 37, the acceleration comparator 37 controls the red indicator light 35 to emit a light, indicating that a severe impact brain injury may have been suffered and life is threatened.

[0030] During installation, it is only necessary to press the inner shell 32 toward the inside of the outer shell 31. At this time, the block 383 will automatically shrink under the action of the arc surface. When the block 383 coincides with the slot 384, the spring 382 will automatically drive the block 383 to reset, thereby realizing the installation of the inner shell 32. During disassembly, it is only necessary to press the pressing plates 393 on both sides to push the block 383 out of the slot 384 through the push rod 391 and the push plate 392, and then the inner shell 32 can be removed. The operation is simple and easy to maintain.
