The present invention provides a wearable medical device based on gesture recognition, having the advantage of quickly waking up the person in nightmares, see fig. 1-6, comprising a hand 1 and a gesture trigger switch 2, the middle finger of said hand 1 being worn with a holder 3;

further, the gesture trigger switch 2 is worn on the index finger of the hand 1 in the form of a ring;

Further, the gesture trigger switch 2 is electrically connected with the gesture recognition chip 5, the gesture trigger switch 2 is electrically connected with the vibrator 4, specifically, the gesture recognition chip 5 has an effect of starting the gesture trigger switch 2 according to recognized gestures, and the gesture trigger switch 2 has an effect of controlling the vibrator 4.

Furthermore, the gesture recognition chip 5 is a photoelectric sensing recognition chip composed of an infrared emission tube, a shielding plate and an infrared receiving tube.

Further, the vibrator 4 is a mobile phone vibrator with a small volume.

Further, the method also comprises an operation process of the vibrator 4, and the specific steps are as follows:

s1, the direct current is used through the sliding contact between the brush and the commutator, the current flows into the coil, the electrified coils of different windings cut magnetic lines of force in the magnetic field formed by the stator group to generate electromagnetic force, the torque formed by the electromagnetic force makes the rotor rotate, the current flowing through the brush circularly performs the process through the action of the steering gear, and the rotor motion is realized;

s2, because there is a vibrator whose center of gravity deviates from the middle, the center of gravity of the rotor is not in the center of the shaft, which causes the unbalance of the rotor, and the rotor will generate vibration because the center of gravity changes continuously during the rotation process;

the method further comprises an operation flow of the gesture recognition chip 5, and the specific steps are as follows:

firstly, an infrared ray beam is emitted by an infrared ray emitting tube;

step two, when the finger swings up and down, the finger drives the shielding plate to shield the infrared beam and reflect the infrared beam to the infrared receiving tube;

when the received signal is in light and shade alternate change, triggering a switch to fix the infrared transmitting tube, the shielding plate and the infrared receiving tube in a relatively stable space, thereby improving the singleness and stability of signal transmission and ensuring the accuracy of signal transmission;

specifically, the gesture recognition chip is mainly divided into a photoelectric sensing recognition chip and a gyroscope recognition chip;

the current photoelectric sensing identification chip comprises: the method is based on the scheme of HALIOSTM developed by elmos company, the functions of the method can meet various challenges brought by gesture recognition, particularly, the product is not influenced by external environment light during working, and the consistency of the functions can be kept in the environment with rapid temperature change;

the scheme is mainly realized by two chips E909.06 and E909.07, E909.06 is a sensor chip which contains a 16-bit singlechip and is manufactured by utilizing a photoelectric technology, the sensor chip can recognize the gesture change of people without contact, E909.07 is a transimpedance amplifier with high performance and high sensitivity, the introduction of the transimpedance amplifier greatly improves the gesture recognition distance of E909.06, and the gesture recognition scheme can recognize simple one-dimensional, two-dimensional and three-dimensional gesture actions;

in principle, the photoelectric sensor system-HALIOSTM of E909.06 emits modulated infrared light outwards, then reflects the infrared light back to the photodiode through an external object (such as a gesture), the photodiode converts an optical signal into an electric signal and transmits the electric signal to the chip after comparing with a signal of another path of compensating pipe, and E909.06 identifies the change of an external gesture according to the change of information data;

although the recognition system based on the photoelectric sensor can recognize some simple gestures, the recognition system has high requirements, the gestures are required to be always in the capture range of infrared light, and the recognition system obviously cannot meet the basic conditions when people are in a sleeping state;

the current gyroscope identification chip: the three-dimensional gesture recognition scheme based on the gyro sensor, which is developed by the enlightenment, is taken as a representative, the working principle is that the gesture action of a person is sensed through a gyroscope, then the gesture action is converted into a digital signal, and the data is sent to a wireless receiver, and the specific hardware equipment is as follows:

the device required by the gesture recognizer is shown in fig. 6, the used angular velocity gyroscope is an IDG300 recognition degree of 2.0 mV/degree/s, some simple gestures of a human body can be sensed, captured gesture changes are converted into digital information through a converter, the central unit of the device is Atmega16, initialization work is mainly completed, recognized digital information is obtained through an Atmega16 information interface, the digital information is transmitted to a wireless transceiver nRf24API, a remote signal transmission device of the recognizer is the nRf24API, the working frequency band of the remote signal transmission device is 2.4GHz, an upper computer is added for preliminarily identifying more gesture information data, the upper computer device is shown in fig. 6 and comprises an Atmega16 single chip microcomputer, an Nrf24API and the like, and the connection mode used by the devices is USB port connection, so that the problem of connection between the devices does not exist;

the chip based on the gyroscope can avoid the requirement on the infrared light capturing range, but the identification difficulty is increased due to the large gesture difference of each person, the accuracy of signal transmission needs to be improved, and the production cost is relatively high due to the fact that more devices are involved and the devices are expensive;

compared with the two identification chips, the photoelectric sensing identification chip consisting of the infrared transmitting tube, the shielding plate and the infrared receiving tube has the advantages of simple principle and relatively low manufacturing cost.

In specific use, a person skilled in the art wears the fixator 3 on the middle finger of the hand 1 and wears the gesture trigger switch 2 on the index finger of the hand 1, when nightmares occur, the finger swings, after swinging, the gesture recognition chip 5 recognizes the finger, and after recognition, the gesture trigger switch 2 controls the vibrator 4 to vibrate the vibrator 4, so that a person in a nightmare state is awakened through the vibrator 4;

the working principle of the gesture recognition chip 5 is as follows: the infrared transmitting tube transmits an infrared beam, when a finger swings up and down, the finger drives the shielding plate to shield and reflect the infrared beam to the infrared receiving tube, and when a received signal is in light and shade alternate change, the switch is triggered to fix the infrared transmitting tube, the shielding plate and the infrared receiving tube in a relatively stable space, so that the singleness and the stability of signal transmission are improved, and the accuracy of signal transmission is ensured;

the working principle of the vibrator 4 is: direct current is used through sliding contact between an electric brush and a commutator, current flows into coils, electrified coils of different windings cut magnetic lines of force in a magnetic field formed by a stator group to generate electromagnetic force, torque formed by the electromagnetic force enables a rotor to rotate, and the current flowing through the electric brush circularly performs the process through the action of a steering gear, so that the rotor is driven, the gravity center of the rotor is not positioned in the center of a shaft due to the fact that the gravity center of the rotor deviates from a middle vibrator on the rotor, the imbalance of the rotor is caused, and the rotor can generate vibration due to the fact that the gravity center of the rotor is continuously changed in the rotating process.
