Among the prior art, have and set up pressure sensor on intelligent bracelet device, the rescuer gets intelligent bracelet device and puts in wounded person's middle part, and during the staff nipped the people through pressure sensor's position, whether it is suitable to detect the dynamics through pressure sensor received pressure.
However, because the place of rescue personnel rescue probably has the radiation, and the protective clothing is worn to the rescue personnel, and inconvenient taking off intelligent bracelet device to also there is danger if taking off protective clothing rescue personnel self in order to take off intelligent bracelet device. Except for this, the force applying mode when nipping people is pressing instead of nipping through the bracelet, so the first-aid effect is greatly reduced.
In the application, the intelligent bracelet device is in a wrist protection shape and can completely wrap the wrist; there is the setpoint on the wrist side surface of intelligence bracelet device for carry out intelligence bracelet device and wear and guide. Put another way, through the setpoint, the staff can wear intelligent bracelet device in bracelet fixed position department to be convenient for accurate collection subsequent data.
Pressure sensor has set firmly on wrist one side of intelligent bracelet device, and pressure sensor corresponds with the interior survey thumb blood vessel department of wrist, and pressure sensor is connected with processing module electricity. When the person pinches, the thumb of the worker exerts force, and in such a state, the blood vessel of the thumb on the inner side of the wrist expands to be convex, and the degree of the convex expansion of the blood vessel changes along with the force exerted by the thumb. The degree of the vasodilatation bulge can be detected through the pressure sensor, and the force exerting size of the thumb can be known.
However, to achieve the above effect, there is a big premise that the rotation angle of the wrist must be at a preset angle; because, if the rotation angle of the wrist is different, even if the thumb is applied with the same force, the degree of the corresponding vasodilation protrusion is different. However, in the first aid, the worker must pay attention to the surrounding environment and the force of the thumb, so that it is difficult to keep the angle of the wrist fixed.
Therefore, in this application, the wrist outside of intelligent bracelet device is equipped with the tension test mechanism along forearm length direction, and the tension test mechanism includes elastic wire and force sensor, and the one end of elastic wire is fixed with the one end that the intelligent bracelet device wrist outside is close to the finger, and the other end is fixed with force sensor, and force sensor fixes the one end that is close to the elbow in the intelligent bracelet device wrist outside. The principle of the tension testing mechanism is similar to that of a portable electronic scale, when the outer side and the inner side of the wrist rotate, the elastic wire can be stretched to generate tension, and the tension sensor can detect the tension and send the tension to the processing module. Put differently, processing module can know the deformation volume of elastic line through force sensor's detected data, and then knows staff's wrist turned angle.
Through the rotation angle of the wrist and the corresponding expansion convex degree of the thumb, the processing module can analyze the actual force of the thumb of the worker at the moment. When the force is applied properly, the processing unit controls the green LED lamp of the reminding unit to light, when the force is applied too small, the processing unit controls the yellow LED lamp of the reminding unit to light, and when the force is applied too large, the processing unit controls the red lamp of the reminding unit to light. Therefore, the force of the thumb of the worker can be guided in real time when the worker takes first aid.
In addition, in this application, processing module still is used for when the data that receive the force sensor continue to reach threshold value X second after, starts the emergency mode. Stated differently, the processing module may initiate the rescue mode after the wrist has been rotated a predetermined angle (e.g., 90 degrees inward wrist bend) for X seconds. Not only is the operation convenient, but also the structure is simplified (the starting device is omitted), and the accidental starting can be avoided because the starting lasts for X seconds.
The foregoing is merely an example of the present invention, and common general knowledge in the field of known specific structures and characteristics is not described herein in any greater extent than that known in the art at the filing date or prior to the priority date of the application, so that those skilled in the art can now appreciate that all of the above-described techniques in this field and have the ability to apply routine experimentation before this date can be combined with one or more of the present teachings to complete and implement the present invention, and that certain typical known structures or known methods do not pose any impediments to the implementation of the present invention by those skilled in the art. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
