At the Winter Olympics, those medical and health black technology

The Olympic Games take "higher, faster, stronger" as the motto, but safety and health is undoubtedly the implicit eternal premise, meet the clear background of the Beijing Winter Olympics scientific and technological innovation, what kind of spark will be sparked when the two meet? Under the threat of O'Mikron and the vision of the "Winter Olympics of Science and Technology", what kind of answer has Beijing handed over?

AOP-KF Solid Alkali: A new generation of air purification materials

AOP-KF solid alkali is a unique air purification material with good sterilization and inactivation effect, especially in the case of the new crown virus.

At the end of 2020, AOP-KF solid alkali masks passed the latest ISO18184: 2019 authoritative certification test, becoming the world's first mask that has been confirmed to be effective in inactivating the new crown virus with an inactivation rate of 99.31% and can be reused many times. At the Winter Olympics, this mask was provided to athletes from all over the world, indicating that the mask can be reused for 7 days, and the front and back of the mask are virus-free for 7 days.

Not only that, but AOP-KF solid alkali is also used directly in the air purification system in the Winter Olympic venues. 30 air purifiers with AOP-KF solid alkali appeared in the venues of both figure skating and short track speed skating, operating 24 hours a day. At the same time, other training bases, training halls, apartments and other venues are also equipped with this air purification system.

Aerosol Inspection System: A new crown inspection system for space

The aerosol is less than 100 microns in diameter and is one of the important ways for the new crown pneumonia virus to spread in a confined environment. The bioaerosol new coronavirus nucleic acid monitoring system can collect and detect bioaerosols in the air, and due to the use of microfluidic platform combined with new nucleic acid extraction and amplification technology, the sensitivity is 10 times that of conventional qPCR methods.

In October 2020, Tsinghua University, Peking University, the Institute of Pathogenic Biology of the Chinese Academy of Medical Sciences, Changping Laboratory and other scientific research units carried out emergency research and jointly developed and completed this public space bioaerosol new coronavirus nucleic acid monitoring system.

The system separates the gas from the aerosol and allows the aerosol to be enriched in a sampling tube. The collection reagent inactivates the virus to ensure that the collected virus samples are no longer contagious. Each collector can collect aerosol particles within 12 cubic meters in 30 minutes, and after 45 minutes of automated integrated testing, the detection conclusion can be drawn. From the beginning of sampling to the feedback of the final results to the epidemic prevention department, the whole process does not exceed 4 hours.

Armpit Band-Aid: The world's smallest wearable continuous intelligent temperature measurement device

In the Winter Olympics test match, the temperature measurement of athletes is used as an "armpit band-aid", which is currently the world's smallest and most accurate wearable continuous intelligent temperature measurement device.

The chip sensor of this "thermometer" is only the size of a grain of sand. People who need to measure temperature only need to stick the device to the skin under the armpit, you can achieve automatic measurement, automatic reporting, once the body temperature is found to be abnormal, the remote detector will issue an early warning, and the temperature taker himself can also get the measurement results at any time after the mobile phone App is associated.

The temperature measurement accuracy of "armpit bandage" is extremely high, reaching 0.05 °C, and the detection accuracy of similar temperature stickers in the United States is 0.1 °C-0.2 °C.

Moreover, the "armpit band-aid" has extremely low power consumption and can be used for 10 days on a single charge.

At present, the upgraded multi-sign sensing device of "armpit band-aid", combined with the big data early warning platform, can achieve 7 monitoring and early warning of body temperature, heart rate, respiratory rate, blood oxygen, exercise, blood pressure and sleep. The Capital Stadium complex has been allocated.

Doping testing: dry blood spot detection technique

Dry blood spot (DBS) testing is a new technique for taking biological samples for doping testing in athletes. Since October 2019, initiated by the World Anti-Doping Organization, the anti-doping centers of the world's 7 major countries, including the China Anti-Doping Center, and international organizations have jointly decided to vigorously promote the dry blood spot detection method, and finally put it into use for the first time this year in the Olympic Games.

In the traditional method, the sampling of the urine test needs to be accompanied by a special person, involving "privacy"; the blood test emphasizes professionalism and procedural correctness, and must be strictly used by medically qualified professionals to draw blood samples, and the blood drawing procedure needs to be recognized and signed by athletes.

Dry blood spots are spots formed after drying finger blood droplets on special cardboard, which can be used for storage, transportation and analysis of trace blood samples. Compared with the traditional blood test method, dry blood spot detection has the unique advantages of micro-sampling, convenient transportation and storage, and more safe and stable solid blood samples, and can be done independently by athletes.

Single-lead, three-lead ECGs: Smart training solutions

This year's short-track speed skating team used single-lead and three-lead electrocardiographs to complete high-frequency sampling through non-inductive wearable devices, and then completed a complete set of smart training solutions through a medical-grade signs data platform.

In high-load exercise training, the athlete's heart rate rises sharply, at this time the heart is very vulnerable to damage, and the hidden problems are more likely to be highlighted and attacked. Single- and three-lead ECGs can provide high-heart rate cardiac risk monitoring and prevent heart damage.

Before exercise, by wearing it for a long time, the ECG monitoring device can screen the athlete for cardiac risk, and can also arrange a personalized training plan for the athlete according to the maximum heart rate and reserve heart rate of the athlete. If after exercise, high-intensity training and competition caused sports injuries, the device can timely screen and detect heart damage to athletes, effectively protecting athletes' safety. By monitoring the recovery status of athletes, coaches can more scientifically develop recovery or post-training plans for athletes.

In the process of post-exercise recovery from sleep, the device can also monitor the sleep quality of athletes, through heart rate and ECG changes, find bad sleep states such as respiratory snoring, intermittent, pseudo-sleep, etc., timely find hidden dangers, and assess their recovery status.

Smart Beds: Create personalized sleep patterns

The Chinese Winter Olympics, which equipped athletes with smart beds that can be intelligently controlled, have made American bobsleigh athlete Summer Britcher praise on his social platform.

The smart bed is 1.2 meters wide, the default length is 2 meters, and it can be adjusted in height, hardness and length. In terms of length, the smart bed is 20 cm as a gear, the maximum can be adjusted to the length of 2.4 meters; in terms of height, the height of the bedside and the foot of the bed can be adjusted separately; in terms of hardness, in addition to the memory sponge mattress, there are also some coconut palm mattresses prepared to meet different needs.

Smart beds can take care of athletes' spines, only need to be set to the right sleeping angle by remote control, memory foam and smart sensors in the mattress can provide athletes with massage and other services. Not only that, but if the sleeping position is uncomfortable and the athlete snores, the smart bed can also help adjust the height of the head for relief.
