Detailed Description
A preferred embodiment of the present utility model will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, an embodiment of a training device for pre-vital capacity detection according to the present utility model includes a filter 1 having an air inlet and an air outlet, wherein the air inlet is detachably connected with a mouthpiece 2, and the air outlet is detachably connected with an air flow expression assembly 3; the air flow expression assembly 3 comprises a connecting pipe 31 and an air flow fan pipe 32 which are sequentially connected to the air outlet, wherein the connecting pipe 31 is provided with a first air flow channel 311 and a second air flow channel 312, a whistle 3111 is arranged in the first air flow channel 311, and the second air flow channel 312 is communicated with the air flow fan pipe 32; the air flow fan tube 32 is provided with an air flow fan blade 321. Specifically, the filter 1, the mouth-containing 2 and the airflow expression component 3 are respectively made of plastic materials, wherein the mouth-containing 2 is tightly matched with the air inlet, and can be detached from the air inlet, and the mouth-containing 2 is consistent with a disposable mouth-containing structure connected with a common pulmonary ventilation function detection device, so that a person to be examined can be assisted to adapt to the mouth-containing.
Further, the airflow fan 321 and the airflow fan tube 32 are concentrically arranged. The air flow fan tube 32 is made of transparent plastic materials, so that a medical staff or a tested person can observe the rotation state of the air flow fan blade 321, and the air flow fan tube 32 is detachably connected with the connecting tube 31 through threads. Specifically, when the exhalation amount or the exhalation time of the subject is short enough to blow the whistle, the air flow enters the air flow fan tube 32 through the second air flow channel 312 to enable the air flow fan 321 to rotate clockwise so as to display weak exhalation performance; and after the subject has been trained for a while, the airflow fan duct 32 may be removed and the subject may be exhaled for training using only the whistle 3111.
