Problems solved by technology
When the medical staff adjust the oxygen supply according to the patient's condition, they need to rotate the adjustment knob according to the rotation direction indicator. It takes several adjustments to make the float accurately reach the position of the scale value. Due to the long-term operation of the device, the sensitivity becomes poor, which increases the difficulty of adjusting the oxygen supply, and artificially observes the position of the float, resulting in large errors and low work efficiency.

The invention discloses a medical float-type oxygen measuring device of an oxygen inhalation apparatus. The oxygen measuring device comprises a flow meter, and a flow regulating valve which is connected to the flow meter, wherein an annular dial is arranged on the outer wall of the valve body of the flow regulating valve; scale lines and scale values representing an oxygen flow regulating range are formed on the dial; the scale lines are distributed in the circumferential direction of the dial, and the scale values on the dial correspond to that on the flow meter one by one; and a triangular bump is formed in the outer wall of a regulating knob of the flow regulating valve. By virtue of the annular dial representing the oxygen flow regulating range on the flow regulating valve, doctors and nurses can rotate the regulating knob according to oxygen supply required by patients so that the triangular bump can accurately indicate the scale line corresponding to the oxygen supply, namely the scale line which is aligned with a float in the flow meter; therefore, the oxygen measuring device is easy in operation, high in accuracy and quite high in value of popularization and application.
Description
technical field [0001] The invention belongs to the technical field of medical devices, in particular to an oxygen metering device of a medical buoy type oxygen inhaler. Background technique [0002] Oxygen inhalation therapy is widely used in clinical treatment and rescue of various patients. In order to ensure the comfort of patients when inhaling oxygen, medical staff usually perform humidification on oxygen. Oxygen inhalers are commonly used equipment for humidifying oxygen, and their function is to provide continuous oxygen at constant pressure and flow for use by patients. At present, the flow meter of the commonly used buoy type oxygen inhaler includes a transparent tube with a scale value. The scale value indicates the adjustment range of the oxygen flow rate. A floating ball is installed in the transparent tube. The adjustment knob can realize the adjustment of the flow rate of oxygen, and the outer surface of the adjustment knob is provided with a rotation directi...
