Air blowing device for excessive ventilation in child electroencephalogram examination

Abstract

The invention discloses an air blowing device for excessive ventilation in child electroencephalogram examination. The air blowing device is characterized by comprising a host, a universal pipe, an air nozzle connecting end, a disposable air nozzle, an elastic buckle, an automatic bubble blowing machine, an air pressure sensor, an A / D converter, a microprocessor chip, a memory and an LED display screen. The device can sense air blown by an air blower, and the information such as the strength and the duration of the blown air is reflected on a host display screen through a special animation interface; when the air blowing duration and the strength reach the standard, the system can control the automatic bubble blowing machine to spray out color bubbles; through the interaction of the animation interface and the feedback result of the color bubbles, the attention of children can be distracted, and the children can be attracted to concentrate on excessive ventilation operation; and after the duration and the strength reach the standard, the device can automatically remind the children to stop blowing air.

Description

technical field [0001] The invention belongs to the technical field of hyperventilation auxiliary equipment for children's electroencephalogram examination, and in particular relates to an air blowing device for hyperventilation in children's electroencephalogram examination. Background technique [0002] Epilepsy is a brain disease characterized by a persistent epilepsy tendency. It is a chronic disease in which the synchronous abnormal discharge of brain neurons leads to transient brain dysfunction. EEG is the most commonly used examination method for epilepsy. Hyperventilation is required during the EEG examination. Hypocapnia and mild respiratory alkalosis in hyperventilation can easily induce epileptic seizures or epileptiform discharges, which improves the positive rate of EEG in the diagnosis of epilepsy and greatly improves the The accuracy rate of special seizure types such as absence seizures. [0003] Generally, the duration of hyperventilation is 3 minutes, the ...

AI Technical Summary

Problems solved by technology

[0003] Generally, the duration of hyperventilation is 3 minutes, the frequency is 20-25 times / min, and the ventilation volume is 5-6 times of normal. Adults can generally cooperate with it, but young children and mentally handicapped children have no self-awareness and cannot cooperate with doctors. Effective hyperventilation; at present, in order to make children cooperate with hyperventilation as much as possible, doctors generally let children blow feathers, pieces of paper or windmills in front of their mouths to attract children's attention, but the effect is not It is very ideal, so it is necessary to design a device that can target children's hyperventilation, which can interact with children, reward them, and attract children's attention so that they can meet the required hyperventilation duration and frequency
