Problems solved by technology

[0002] Infusion is a commonly used medical method. In the process of infusion, the drip rate of the droplet should be well controlled. If the drip rate is too slow, it will affect the rate of infusion, and if the drip rate is too fast, it will cause discomfort to the patient.
In addition, if the needle bulges during the infusion, the droplet speed will slow down significantly.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an infusion set with a liquid level monitoring device. Background technique [0002] Infusion is a commonly used medical method. In the process of infusion, the drip speed of the liquid drop should be well controlled. If the drip speed is too slow, it will affect the rate of infusion, and if the drip speed is too fast, it will cause discomfort to the patient. In addition, if the needle bulges during the infusion, the droplet speed will slow down significantly. During the infusion process, especially when unattended, it is very important to monitor the liquid level in the infusion set to ensure the safety of infusion. Contents of the invention [0003] The purpose of the present invention is to provide a liquid drop monitoring device for an infusion set, which is used for real-time monitoring of the liquid level in the infusion set to ensure the safety of infusion. ...
