This invention discloses an olfactory electrostimulation model for automatically generating current stimulation signals for an artificial nose, relating to the technical field of olfactory stimulation signal generation using biomimetic neural networks. The implementation steps include: First, constructing a biomimetic neural network framework. Based on the neuronal anatomical structure of the olfactory epithelium and olfactory bulb system, extracting the main neuron types, and organizing them according to their connection methods in biological systems; Second, using the Hindmarsh-Rose neuron model to model various neurons in the constructed network and simulate their dynamic firing behavior; Subsequently, setting the connection weights between neurons and the interlayer transmission current to realize the computational model of the entire biomimetic neural network; Finally, in the odor encoding and stimulation signal generation stage, the odor detection curve of the electronic nose is used as an external stimulus input to the biomimetic neural network. The network calculates and generates a series of peak signals, which are output as current stimulation signals to the olfactory bulb for stimulation, thereby realizing the olfactory induction function of the artificial nose.

The utility model discloses an artificial nose capable of preventing facial indentation, which comprises an artificial nose body, an air delivery pipe and an intubation tube, the air delivery pipe and the intubation tube are communicated with the input end and the output end of the artificial nose body, and a telescopic tube used for adjusting length and a steering tube used for adjusting orientation are additionally arranged between the intubation tube and the output end of the artificial nose body. The position of the artificial nose body can be adjusted through the telescopic pipe, so that the artificial nose body can avoid the face of a patient and can move to a bed surface on the outer side of the face of the patient, and due to the hardness of the material of the artificial nose body, the situation that a pipeline is blocked due to bending and the air conveying function is affected is avoided; the device can be matched with the telescopic pipe to move to an area which does not hinder operation of a doctor, and operation hindrance cannot be caused.

This invention discloses a functional prototype of an external head-mounted odor pickup device for an artificial nose, belonging to the interdisciplinary field of analytical detection technology and wearable devices. It adopts an integrated hat-and-glasses design architecture. The overall structural layout uses a modular design, integrating multiple modules into the hat, with the glasses section housing the air intake pipe. The concealed airway system utilizes the structure from the temples to the nose pads as the air intake pipe, delivering gas from the nose pads to the brim air chamber via micro-tubes, and then expelling it from the back of the hat. The optical path adaptive air chamber dynamically adjusts the position of the optical signal receiver using a micro-actuator, combined with a control algorithm to achieve intelligent adjustment of the optical path. The periodic sampling and signal processing method monitors the respiratory cycle using a respiratory airflow sensor, performing gas sampling and detection during inhalation and airway cleaning during exhalation, achieving a detection cycle synchronized with the respiratory rhythm. This system achieves accurate detection and long-term dynamic monitoring of the wearable electronic nose over a wide concentration range.

Conventional artificial noses have the problem that sputum and other substances mixed with the patient's exhaled breath can cause airway obstruction within the artificial nose housing. [Solution] In the artificial nose 10 of the present invention, a plurality of recesses 41 are formed around the opening 27B on the end face 27A of the housing portion 20, and a first wall portion 42 is formed that extends to the inside of the opening 27B. With this structure, even if sputum 61 mixed in the patient's exhaled breath enters the housing portion 20, the sputum is retained in the recesses 41, making it less likely for airway obstruction by sputum 61 to occur. As a result, the respiratory burden on the patient is reduced, and clogging of the first filter 33 due to the sputum 61 is prevented.

The invention discloses an artificial nose integrated broken tube alarm system based on MEMS air pressure induction, and relates to the technical field of medical instruments. The system comprises an artificial nose body, an MEMS air pressure sensor and a flow detection element which are arranged in the artificial nose body, and a control module, an electronic buzzer, a passive acoustic whistle structure and a power supply module which are arranged outside the artificial nose body. Redundant logic judgment is carried out through air pressure and air flow double signals, normal fluctuation and pipe breakage events are effectively distinguished, and the false alarm rate is remarkably reduced; and a double-insurance alarm mechanism is formed by the electronic buzzer and the mechanical reed, so that even under the extreme condition of battery failure, the passive acoustic reed can still give an alarm through sounding, and extremely high reliability is realized. The whole system is disposable consumables, the circuit is simple, the cost is low, the system and the artificial nose can be integrally packaged and independently work, the system is particularly suitable for operating rooms, ICUs, patient transfer and other scenes, and the problems that in the prior art, dependence on host equipment is high, alarm is delayed, and power failure fails are effectively solved.
