Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a double-head infusion set. Background Art

[0002] Infusion sets are one of the conventional medical supplies and have been widely used in clinical practice. Currently, most of the infusion sets commonly used in hospitals are single-channel infusion sets. In the actual infusion treatment process, the patient's body position, the height of the infusion bag, the retention of the indwelling needle, etc. will affect the infusion speed. It is unrealistic to control the dripping speed by manual supervision. We urgently need an instrument that can replace our naked eyes to monitor at all times and adjust the infusion speed according to the setting requirements. Among them, the application number is "CN201721370985.2". An infusion device described in the utility model detects the dripping rate in the Murphy dropper by setting an automatic monitoring device, and transmits the signal to the roller control device. The roller is controlled by the roller control device to change the infusion rate. Automatic adjustment is performed without manual monitoring, avoiding occupying more manpower and saving resources. However, there is still room for improvement when the infusion device is used: the infusion device has only one puncture device. When the liquid in the infusion bottle is about to be infused or has been infused, the medicine bottle must be replaced in time. In the case of many patients during the flu season, the traditional infusion device will bring a great workload to medical staff, causing fatigue to medical staff. Utility Model Content
