A bottle of liquid capacity of ampoule 25ml into the instrument at the bayonet, press the OK button, the bottle is fed into the machine, by the two fan blade cutting the bottle, with the "bang", the instrument will be the bottle pushed off, then by needle aspiration into the liquid infusion bag; the other side, the liquid resistant bottles the machine also entered the similar operation, only 30 seconds to 40 seconds, can finish a bottle of liquid medicine with intravenous infusion.

This is a venous dispensing robot invented by Zheng Yongqiang, deputy director of the emergency department of the first people's Hospital of Chengdu. Zheng Yongqiang suffered many setbacks and took 14 years to lead the team to independently research and develop the robot. The technology has gained 120 national patents, and 17 international patents are being applied.

It is understood that the robot is expected to carry out mass production promotion at the end of the year, which will replace the nurse dispensing, which is of great significance for improving the dispensing efficiency and protecting medical staff.

research and development

The biggest difficulty in cutting and interrupting the mouth of the bottle

Zheng Yongqiang has devoted 14 years to the success of the research and development of the venous dispensing robot.

"I like machinery since I was a child." Zheng Yongqiang said that there was nothing to do with it before, and most of it was thinking in his mind. After work, whenever there is an intelligent mechanical exhibition, he will go to the scene to watch. In those years, he has seen exhibitions in Shanghai, Beijing and Guangzhou, and the number of exhibitions has been countless.

In 2002, Zheng Yongqiang began to think about the development of intravenous drug dispensing robot. At that time, he still worked alone. "I can't draw pictures, and then find a mechanic friend to draw for me." Later, there were friends, programmers, and so on. In 2014, a company was set up for R & D, and the test machine was completed in the first half of this year.

In fact, in 2005, Zheng Yongqiang completed a semi-automatic dispensing robot, but because of cost and other reasons, it is difficult to carry out the promotion. But he knows this field has a wide market in the country and has never given up. In early 2009, he helped a company in Shenzhen to make an intravenous infusion dispensing robot. Because of its high cost and large area, it dispensed only more than 60 bottles per hour, which could not meet the clinical needs.

R & D is not a smooth sailing, and Zheng Yongqiang once thought of giving up. "At that time, the most difficult, is the bottle mouth cutting and too light cut constantly interrupted - bottle, too heavy and easy to break the bottle, only this one through thousands of tests."

Zheng Yongqiang recalled that he was sometimes inspired by the night, and had to communicate with the mechanical and engineering personnel, and forget to eat it often. And often after 24 hours of continuous work, he drove to Guanghan to continue its research and development.

At present, in addition to the motor and screw, the other parts of the robot are developed and manufactured independently. "Each robot has four units, which can operate at the same time. Each unit is made up of two parts, one is the Xilin bottle, the other is the ampoule bottle. Zheng Yongqiang said that each unit of the test machine can only put one bottle of liquid, and each unit of the official machine can put 4~5 bottles of liquid.

Effect

Improving the efficiency of dispensing and protecting the medical and nursing staff

Zheng Yongqiang introduced that intravenous drug dispensing robot is mainly applied to nursing station. After using intravenous drug dispensing robot, it can improve labor efficiency, reduce labor intensity and protect medical staff. "It is the replacement of the manual part of the dispensing machine with machinery."

According to the introduction, the current drug dispensing mainly relies on artificial labor, which can be roughly divided into seven steps, namely, disinfection, suction of mother liquor, water injection into the West Lin bottle, water injection to two circles, needle withdrawal, shake or concussion, extraction of liquid medicine, infusion of mother liquor bag, separation of syringe needle. Zheng Yongqiang said that this way is very demanding for the labor intensity of dispensing pharmacists, and prone to dispensing errors. The bottle glass is also easy to cut the nurses' occupational hazards to dispensing pharmacists. In addition, the nurse inadvertently encountered the empty needle part during the dispensing process, and it also easily led to the contamination of the liquid.

In addition, "venous dispensing robots are helpful to solve medical disputes." Zheng Yongqiang said that in the future, the type, dose, time, and other treatment of the patient's medicine are available, and can be monitored in real time.

The robot has a great advantage in improving work efficiency. "The ordinary nurse can match 25~30 bottles per hour and reach 30~40 bottles skillfully. And the robot can match 300 bottles of liquid every hour. " Zheng Yongqiang said that the vein dispensing robot developed by ourselves, compared with intravenous dispensing robot developed by the United States, smaller area, only 1~2 square meters; the liquid can only handle a vial intravenous dispensing robot developed by the United States, 60~70 bottles of liquid medicine per hour, while the liquid dispensing robot developed by ourselves can vein treatment vials and ampoules every hour, with 300 bottles, can fully meet the needs of clinical medication.

"The price of a machine in the United States is 15 million yuan, and our cost is lower."  Zheng Yongqiang said that the start of the promotion, the cost is expected to be 1 million ~150 million / Taiwan, in the future may be reduced to 200 thousand ~30 million / Taiwan, so that community hospitals can also be used.

Future

Forecast of mass production at the end of the year

Today, this intravenous dispensing robot will assemble and finally debug the clinical prototype. It is expected that mass production will be implemented by the end of this year to the beginning of next year, and the plan will be promoted from top to bottom to community hospitals.

According to the introduction, the robot will take part in the national medical robot conference in Chengdu in September 24th. It will be displayed and explained on the scene, in the hospital of Chengdu, the provincial people's medicine.
