An infusion set with a liquid level monitoring device is used for real-time monitoring of the liquid level in the infusion set to ensure the safety of infusion. It includes an infusion hose, a venous needle, a liquid medicine filter, a flow rate regulator, and an air filter for an intake pipe, and is characterized in that it also includes a liquid level monitoring device, which includes a drip funnel, a water wheel, a rotating shaft, Turntable, proximity switch, insert block, controller and sensor are provided with a rotating shaft on the dripping funnel, and a water wheel is arranged on the rotating shaft. The liquid droplets in the infusion hose drop on the blades of the water wheel to drive the water wheel to rotate. A turntable is fixed on the rotating shaft outside the dripping hopper, and an insert is provided on the side wall of the dripping hopper. The sensor on the insert can interact with the proximity switch on the turntable to sense the rotation of the water wheel; when the water wheel is no longer When turning, the sensor does not sense the signal, so it sends a signal to the controller and sends a signal to the nurse to ensure the safety of infusion.

The invention discloses a direct-pressure-supplementing type high-temperature steam circulation system which comprises a water storage tank, a high pressure pump, a vaporizer, a high pressure buffer tank, a steam compressor, a temperature and humidity regulator, and a steam using unit. An inlet of the vaporizer is connected with an outlet of the water storage tank by the high pressure pump. An outlet of the vaporizer communicates with an inlet of the high pressure buffer tank. An outlet of the top of the high pressure buffer tank communicates with an inlet of the steam compressor. An outlet ofthe steam compressor communicates with an inlet of the temperature and humidity regulator. An outlet of the temperature and humidity regulator communicates with an inlet of the steam using unit. An outlet of the steam using unit communicates with the inlet of the high pressure buffer tank. An outlet of the bottom of the high pressure buffer tank communicates with the inlet of the vaporizer. According to the direct-pressure-supplementing type high-temperature steam circulation system, high pressure wet steam or superheated steam discharged from the steam using unit can be directly subjected totemperature and pressure increasing to the target high temperature and high pressure steam parameter at the inlet of the steam using unit, stored energy of mediums discharged from the steam using unit can be fully utilized, and significant energy-saving benefits are provided.
