For many people
Injections are one of the nightmares from childhood to adulthood
Will it be possible to get a vaccine without a needle in the future?
This team from Tongji University helps you realize your dreams!
January 17
The team of Associate Professor Qi Peng of Tongji University released
The first autonomous intelligent needleless vaccine injection robot in China
This robot is called "Houyi"
It automatically pinpoints the position of the vaccine on a person's shoulder
Needle-free injection is used
The whole process of unmanned completion of the vaccine injection
So here's the problem
Needle-free injection, can it be accurate? Does it hurt?
Qi Peng introduced that the automatic vaccine injection robot can automatically identify the designated vaccine injection location on the human body, such as the commonly used deltoid muscle part of the upper limb of the human body.
The injection process is roughly divided into three steps
▽
First of all, the automatic vaccine injection robot shoots the human body through a simple three-dimensional point cloud camera, quickly and automatically fits the three-dimensional model of the corresponding part of the human body, and accurately identifies the vaccine injection site and injection angle.
At the same time, the seven-axis force control adaptive robot arm has high-precision, rapid response force control performance, and the application of high-precision force control lamination algorithm can ensure that the end of the syringe is vertically and closely fitted to the injection site, improving the injection effect and reducing the pain experience.
The needleless injection part of the robot is then able to pass through a high-pressure column of water, pushing the agent through a very fine nozzle, forming a jet that passes through the skin at high speed and directly into the treatment site. The drug tube is sterile for single use, which is discarded after injection to ensure safe use.
He also introduced that for the hospital application scenario of vaccine injection, the current robot injection system uses air pressure drive technology, which has the advantage of being suitable for rapid continuous injection. The liquid injection can be completed in half a second, and the injection accuracy can be accurate to 0.01mL, which can be adapted to the requirements of different vaccines for the injection dose. At the same time, it also has the function of injection depth regulation, which can be applied to different types of vaccines injected subcutaneously or intramuscularly. The closer the syringe head fits to the surface of the skin and the more vertical the contact angle, the better the injection effect and the less pain it feels.
Netizens said that they were more afraid
