A new intravenous therapy device invented by a Chinese doctor changes the method of depending on the gravity drip used worldwide for the past 110 years, its inventor said on Monday.

Xu Lixian, a professor and doctor in the dental hospital under the Fourth Military Medical University in Xi'an, Shaanxi province, created and developed a portable multifunction automatic control infusion device which is safer, more comfortable and convenient than the old gravity drip device.
