Problems solved by technology
However, because the previous respiratory provider did not have any device design for indicating the humidity of the airflow, it is often difficult for nurses to judge the humidity of the airflow. Excessively high or too low humidity in the airflow will cause discomfort to the patient's breathing, especially for For unconscious patients, even if they have breathing discomfort, they cannot take the initiative to inform the nursing staff, so there is a problem of safety in use

Embodiment Construction
[0023] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.
[0024] Such as figure 1 , 2 Shown is the first preferred embodiment of the airflow change indicating device 2 of the present invention, which includes a housing 21 for gas circulation, a circulation indicator set in the housing 21 and capable of moving and displacing with the airflow The unit 22 , a humidity indicating unit 23 arranged in the casing 21 and capable of indicating the humidity condition of the airflow through color changes, and a pressure relief unit 24 arranged on the casing 21 .
[0025] The casing 21 has an input end 211 , an output end 212 opposite to the input end 211 , and a chamber 213 defined between the input end 211 and the output end 212 . The part of the casing 21 located between the input end 211 and the output end 212 may be made of transparent material as a whole, or may only partia...

An airflow change indicating device for use with a gas generator. The airflow change indicating device includes a housing through which the gas output by the gas generator can circulate, and a housing which is arranged in the housing and has a movable displacement with the airflow. A circulation indicating unit, a humidity indicating unit which is set in the casing and can indicate the humidity condition of the airflow with color changes, and a pressure relief unit which is arranged on the casing; the pressure relief unit has a function when the air pressure in the casing is too large A pressure relief valve that opens in good time, and a pressure relief hole that can release the high-pressure airflow in the casing after the pressure relief valve is opened; this allows the user to observe and understand the airflow status and humidity, and it can be more effective when the air pressure is too high Provide timely pressure relief and whistle warning function.
Description
【Technical field】 [0001] The present invention relates to an airflow change indicating device, in particular to an airflow change indicating device which can allow users to observe and understand the airflow circulation condition and humidity, and can release the pressure in time when the air pressure is too high and warn with a whistle. 【Background technique】 [0002] In the past, the design of the breathing supplier usually included an oxygen supply source, a control valve on the oxygen supply source to adjust the oxygen output and air pressure, a delivery tube on the control valve for transmitting oxygen, and a A mask at the other end of the delivery tube. In use, as long as the mask is placed on the mouth and nose of the patient, after the oxygen supply source is turned on, the oxygen will be output from the control valve, delivered through the delivery tube to the mask for the patient to inhale. In addition, some breathing supplies have a flow meter on the control valv...
