Abstract
Description
Technical Field
[0001] The utility model relates to a mouth pad for lung function examination, in particular to an infection-proof lung function mouth pad and a medicine inhalation device for lung function examination. Background Art
[0002] In the existing drug inhalation device for pulmonary function examination, a mouth pad is put on the outer sleeve of the three-way device, and then a medicine bottle is installed on the three-way device. After inhaling through the mouth pad, the drug solution is inhaled. After use, the mouth pad is discarded as a consumable, while the three-way device continues to be used. After the three-way device continues to be used, the previous patient and the next patient will share the same channel. Because it is difficult to ensure that the patient only inhales and does not exhale when inhaling the medicine, the gas exhaled by the previous patient will enter the three-way device, and the bacteria and viruses contained in the gas will adhere to the inner wall of the three-way device. When the next patient uses it, it is easy to inhale the bacteria and viruses into the mouth, which is easy to cause cross infection. If it is wiped with alcohol, the inside of the three-way device will be moist, affecting the accuracy of the result. Secondly, the patient is easy to inhale the alcohol gas volatilized after the alcohol wipe of the three-way device during the examination, resulting in airway hyperreactivity, which further affects the accuracy.
[0003] In view of the shortcomings of the existing drug inhalation devices for pulmonary function tests, the inventors conducted investigations and searches and found that some hospitals integrated the mouth pad and the three-way device, and both the mouth pad and the three-way device were used as consumables. Although this solved the problem of cross infection, the cost was high and the three-way device needed to be connected to the instrument each time, which was also time-consuming.
