How many steps will it take to build a hospital in space?

People who eat whole grains will inevitably get sick

Du Jichen had thought of these things for a long time

On the evening of November 18, the "2021 International Symposium on the Peaceful Use of Space Technology (Health)" opened in Beijing in an online format.

The successful exploration of outer space is one of the greatest practices in human history

Du Jichen introduced that the current record of personal cumulative space flight has reached 879 days, and the longest distance that human spacecraft can reach is more than 400,000 kilometers from the earth

The space hospital he envisions is a comprehensive medical body set up in space, which can not only provide full care of health monitoring, disease diagnosis and preventive rehabilitation for personnel entering space, but also provide special diagnosis and treatment services for intractable diseases on Earth

How to build a space hospital? Du Jichen believes that the space hospital needs to have an inspection and diagnosis system, a treatment system and a rehabilitation system

As we all know, traditional medical imaging equipment such as CT and magnetic resonance cannot be carried in space due to the disadvantages of large size, difficult movement, high radiation coefficient, and high magnetic field

He said that the development of disease diagnosis standards for space hospitals is a key link and a necessary prerequisite for clinical medical research in space

For example, taking medicine is not the same thing on Earth and in space

"This requires us to study drug preparations suitable for the space environment, explore multiple routes of administration, and formulate medication guidelines that are different from those on the ground

If surgery is to be performed in space, the situation is more complicated

Does it sound sci-fi? Since human beings have successfully achieved space survival, medical needs and exploration have always been around, and the idea of ​​a space hospital is not a tree without roots

In his view, the construction of a space hospital is a systematic project, "The achievement of this task is by no means achievable by a single field or technical team.

Du Jichen believes that in the future, when the space hospital is completed in the universe, it will surely contribute its due wisdom and strength to human deep space exploration and long-term space survival
