Problems solved by technology

However, so far, this index has not been used to measure airway hyperresponsiveness at home and abroad, but indirect indicators such as forced expiratory volume in one second (FEV1), airway resistance, etc.
[0003] There are several reasons why wheeze is not used: 1. The occurrence of wheeze is sudden and sudden, which cannot be predicted in advance; 2. There is no relevant medical device in clinical practice, so the wheeze cannot be recorded ;3. The wheezing sound cannot be recognized by the computer, and it cannot be synchronized with the respiratory waveform, so it cannot be marked on the respiratory waveform; 4. The paper report cannot be printed out for permanent storage. 5. The judgment of the wheezing sound is not standardized, etc.
[0004] At present, the airway hyperresponse measurement equipment used in China is generally imported from Japan, Europe and the United States and other countries. There is no such product produced in my country. Even if the imported products are used, there are many disadvantages. For example, this type of quantitative inhalation device has the following disadvantages: ①The price is relatively expensive, which increases the purchase cost; ②It is inconvenient to manually change the drug concentration; ③The FEV1 measurement needs to be repeated, which takes a long time; ④The drug inhalation and FEV1 detection cannot be synchronized ⑤ There are many unsafe factors in the measurement process: if the program is fixed and cannot be interrupted, there are too many inhaled drugs, and it is impossible to inhale the relief drugs in a timely, rapid and effective manner, bronchodilators need to be used manually, and the subjects need to cooperate with them

Embodiment Construction

[0031] Such as figure 1 with figure 2 As shown, the multi-channel detection airway provocation tester for wheeze sounds, including:

[0032] Drug atomization device 1, the drug atomization device 1 uses an air compression pump as a power source, and is used to atomize experimental drugs for inhalation by subjects. The drug atomization device 1 includes at least one jet nebulizer. There is a mouth tube on the device. In this embodiment, the working principle of the drug atomization device 1 is the same as the atomization device involved in the applicant's invention patent ZL200910225753.1. to repeat;

[0033] The input device, the input device includes several electrode patches 2 and several pickups 3 for picking up wheezing sounds, the electrode patches 2 and the pickups 3 are integrally arranged, as figure 2 As shown in , the electrode joint 21 of the electrode patch 2 is located on one side of the electrode patch 2, the pickup 3 is arranged on the other side of the elec...

Abstract

The invention discloses a wheeze sound multi-channel detection airway excitation tester and a method for picking up and applying the wheeze sound, comprising a drug atomization device, several pickups for picking up the wheeze sound, and a device for collecting the wheeze sound A controller for amplification processing, analog-to-digital conversion, synchronous conversion, and calculation processing of signals input by the pickup and electrode patches, and an output device, which is electrically connected to the controller for image display, audio playback, and electronic medical record printout. Since the pickup is set, the wheezing sound can be collected, and the wheezing sound can be picked up; because the controller, memory and output device are set, the collected signal is processed by the controller, and the generation of the wheezing sound is judged and analyzed. , and synchronize the wheezing sound with the respiratory waveform, the storage of the wheezing sound can be realized through the memory, and the playback, restoration, real-time recording, marking and printing of the wheezing sound can be realized through the output device due to the setting of the output device.

Description

technical field [0001] The invention relates to the technical field of asthma diagnosis and treatment equipment, in particular to a wheeze sound multi-channel detection airway provocation tester and a method for picking up and applying the wheeze sound. Background technique [0002] Wheeze is the most important feature of asthma. The production of wheeze is not controlled by consciousness. It is the most direct sign of asthma attack and the most objective observation index of asthma. The appearance of wheeze is mainly due to the extensive bronchiole spasm in the lungs. When exhaling, the airflow passes through the narrow bronchiole lumen and produces a pathological breathing sound, which is most obvious during exhaling. However, so far, this index has not been used to measure airway hyperresponsiveness at home and abroad, but indirect indicators such as forced expiratory volume in one second (FEV1) and airway resistance have been used for testing. [0003] There are several...
