Precision infusion set: a new type of precision infusion set with a new structure that replaces the traditional dripping speed adjustment method with air speed control, precision filtration of air and liquid medicine, and automatic exhaust function. It is characterized by: a new type of air fine filter with drip rate adjustment scale and gas phase membrane, and a liquid medicine fine filter with automatic exhaust mechanism and liquid membrane; eliminating the drop bucket and small wheel of ordinary disposable infusion sets Drip speed regulator. It solves the shortcoming that the current disposable infusion set cannot efficiently remove the insoluble particles that block the capillaries, adjusts the tick speed intuitively and accurately to adapt to chemotherapy, infants, critical patients, SARS, infectious wards, and of course it is also suitable for ordinary patients.

Ordinary infusion set: Can not filter bacteria, only filter particles, because the size of the bacteria is smaller than the micron level, and the micropores in the air filter device are larger than the micron. The special precision infusion set can effectively reduce the particulate pollution in the air during the infusion process. The filter pore size of the ordinary infusion set can not reach the fine particles produced in the process of filtering the infusion liquid. However, precision infusion sets are much more expensive than ordinary infusion sets in terms of price. It is safer to choose precision infusion sets for infusion if conditions permit.
