Problems solved by technology
[0002] At present, there is no equipment on the connecting tube between the oxygen mask and the oxygen supply end in clinical use. When the patient is doing nebulization treatment or other treatment, the medicine is mixed in the oxygen for the patient to use, but when using it, the doctor's dosage is usually It is carried out according to the patient's condition, that is, the therapeutic effect is achieved by using all the medicine on the patient. In actual use, the patient can only inhale the medicine when inhaling, and the medicine is directly discharged out of the tube when exhaling, reaching Therefore, it often fails to achieve the effect of the doctor's prescription dosage, and causes a lot of waste of drugs

Embodiment 1
[0021] like figure 1 As shown, this embodiment provides a gating device for detecting changes in air flow, including an oxygen mask 1; the oxygen mask 1 is provided with a connecting pipe 2 integrated with the oxygen mask 1, and is provided with an external oxygen supply terminal connected, wherein the connecting pipe 2 is provided with a detection device 4 and a gate control device 5;
[0022] The detection device 4 is used to detect the flow direction of the gas in the connecting pipe 2, compare it with the preset gas flow direction, and output the comparison result of the gas flow direction;
[0023] The gate control device 5 is connected with the detection device 4, and is controlled by the comparison result to close or open the control valve of the connecting pipe 2. The control valve is arranged inside the gate control device 5. When the control valve is closed When the valve is closed, the air flow passage of the connecting pipe 2 is closed, and when the control valve ...

The invention discloses gating equipment used for detecting airflow change, comprising an oxygen mask, wherein a connecting pipe is arranged on the oxygen mask and is connected with an oxygen supply end; a detecting device and a gating device are arranged on the connecting pipe; the detecting device is used for detecting the flow direction of gas in the connecting pipe, comparing the flow direction with a preset gas flow direction and outputting a comparison result of the gas flow direction; the gating device is connected with the detecting device and is used for controlling a control valve which is used for opening or closing the connecting pipe according to the comparison result. According to the gating equipment used for detecting airflow change, the detecting device and the gating device are arranged on the connecting pipe between the oxygen mask and the oxygen supply end; when a mixed aerosol of oxygen and medicine is inhaled, the valve on the connecting pipe is opened; when in-vivo gas is exhaled, the valve on the connecting pipe is closed, the accurate dosage of the medicine can be ensured, and the medicine waste can be avoided.
Description
technical field [0001] The invention relates to a medical care device in a medical device, in particular to a door control device for detecting changes in air flow. Background technique [0002] At present, there is no equipment on the connecting tube between the oxygen mask and the oxygen supply end in clinical use. When the patient is doing nebulization treatment or other treatment, the medicine is mixed in the oxygen for the patient to use, but when using it, the doctor's dosage is usually It is carried out according to the patient's condition, that is, the therapeutic effect is achieved by using all the medicine on the patient. In actual use, the patient can only inhale the medicine when inhaling, and the medicine is directly discharged out of the tube when exhaling, reaching Therefore, the effect of the doctor's prescription dosage is often not reached, and a large amount of waste of medicine is caused. [0003] Therefore, there are defects in the prior art and need to...
