"The most beautiful Medal" of caring for the war "epidemic" Warriors
Since the start of novel coronavirus pneumonia, we have touched the face of a medical staff. As a result of wearing masks and goggles for a long time, there are many indentations, redness, swelling and even ulceration, which are known as "the most beautiful Medal", but they are painful in the eyes.
How to avoid indentation while not affecting the protection performance? The clinical front-line workers and R & D enterprises of the 10th people's Hospital Affiliated to Tongji University worked together on the platform set up by the special committee of medical research management of Shanghai Medical Association and the patent research and transformation center of Tongji University Medical College, and successfully launched the warm heart invention - the head mask pressure sore protection patch, which will soon be put into mass production.

There are worries about the most beautiful Medal
Although the mask is light and thin, due to the need to closely fit the face to achieve the protective effect, combined with the individual differences of facial contour, wearing it for a long time will inevitably cause pressure on the zygoma, bridge of nose, cheek, ear and other parts. Needless to say, the N95 masks and goggles that are more suitable for the face and have better air tightness are used by the first-line medical staff.
Although a series of indentations are known as the "most beautiful Medal" of medical staff, in fact, indentations will not only cause pain, but also affect local blood circulation and lymphatic reflux. Over time, they will inevitably lead to pressure sores, with slight congestion, edema, and severe ulceration. Therefore, how to avoid or relieve pressure sores of masks has become one of the most realistic needs of medical staff in the front line of war "epidemic".
Some medical staff have no choice but to use band aid as a "cushion", but the effect is limited. On the other hand, it may affect the air tightness of the mask, which may lead to infection.

Inspiration from clinical needs
How to solve the big trouble caused by small masks and better care for medical staff? At the beginning of February, led by Vice President Li Jiyu, the joint research and development enterprise established the "R & D project team of head anti pressure sore protective dressing", striving to complete the R & D, design and production as soon as possible, and solve the pain of colleagues who are struggling in the front line at the first time.
In order to find the exact pressure point, the R & D team often wears goggles and masks to find the pressure point and pressure range, which is often worn for one day. In order to maximize comfort, R & D personnel paste all kinds of water colloids, silicone gel, pressure sensitive adhesive and other materials on different parts of the face for "human body test". They usually stick for 24 hours or 48 hours. Finally, a gel foam composite structure with weak skin sensitivity, good cushioning effect and sweat absorbability is selected as dressing material.
In the dressing material, the PU film on the outer layer is waterproof and breathable; the polymer material on the middle layer can effectively absorb the moisture exhaled by the human body, so as to avoid the decline of the protective performance caused by the wet mask; the silicone material on the inner layer can not only provide the elastic buffer, but also avoid the allergic reaction caused by the common rubber material.
The product R & D and design are completed. When protesting the wearing of goggles and N95 mask, the compression damage on the cheeks, bridge of nose, forehead, mastoid behind the ears and other parts will be taken into account. Through the design of butterfly wing shape and crescent shape in different parts, not only the facial tissue will be fully protected from pressure sores, but also the firmness and comfort of application will be taken into account, and it can be confirmed After a long time of application, there will be no tearing pain.

The first line of pain of intelligent solution war "epidemic"
On February 21, the first batch of sample proofing was completed. On February 24, only two weeks after the R & D team approved the project, Yan Zhe, the head nurse, and Gao Meili became the first batch of medical staff on probation in the fever observation ward cleaning area of the hospital.
From the beginning of the fight against the epidemic, they fought on the front line. When they took off their masks, there were deep indentations on their cheekbones. With the help of the R & D personnel, they put on the nose patch, forehead patch and ear patch, and then put on the masks and goggles, which made them feel much more comfortable at once, and their smiles were more confident and calm.
At present, the invention design has completed patent application and transfer of R & D enterprises, and will be put into mass production as soon as possible. The first batch of products will be supplied to the front line of anti epidemic in Wuhan free of charge, contributing to the wisdom of the 10th Academy for the war of "epidemic".

Contributed wisdom and strength!
Lung ultrasound is no longer a restricted area!
Novel coronavirus pneumonia was successfully diagnosed and helped to rescue a dying old patient with a new crown pneumonia in Wuhan during a local treatment in February 1st. It is fully demonstrated that ultrasound technology and equipment can play a more important role in the prevention and control of epidemic diseases. More and more ultrasound doctors are going to work in the quarantine area.
With the progress of medical science and technology in recent years, the role of ultrasound image in the diagnosis of lung diseases is increasingly prominent, and the air-containing hollow organs are no longer the "forbidden area" of medical ultrasound. Doctors outside the isolation area can carry out ultrasonic examination for patients through 5g technology or remote control of ultrasonic robot in the isolation area through the handle. Shanghai ultrasound diagnosis and treatment engineering technology research center relies on the construction of the 10th Affiliated People's hospital.

Tongji wisdom of ultrasound doctors
According to experts in the ultrasound department of the hospital, the mobile ultrasound equipment is small and flexible, which can go deep into the isolation area at any time to carry out bedside inspection on the spot, in order to cope with the rapidly changing clinical emergencies; in addition, the ultrasound equipment can carry out real-time remote consultation based on the cloud platform with the support of robot or 5g wireless network technology, which can effectively avoid cross infection of medical workers.
Recently, the NCP bedside ultrasound and long-range ultrasound wartime emergency meeting hosted by the National Health Commission capacity building and continuing education center and organized by Shanghai ultrasound diagnosis and treatment engineering technology research center was held online. At the meeting, experts have summarized ultrasound images with characteristics and diagnostic significance; relevant clinical cases have formed a written experience summary and released at this online meeting. The remote ultrasound system developed by the engineering center has also been put into use in designated hospitals in Wuhan and has won high praise. It is of great significance to promote the application of mobile ultrasound and remote ultrasound in epidemic prevention and control. To further optimize the novel coronavirus pneumonia infection control and prevention of new crown pneumonia, the online conference also issued the guidance of Shanghai municipal ultrasound quality control, which provided detailed plans for the protection of the subjects, the front desk triage, medical personnel, general consulting room, special consulting room, and disinfection of ultrasonic equipment, in order to protect the safety of patients and medical personnel. It provides institutional support.
Ultrasound doctors, a special group, are also making positive contributions to epidemic prevention and control in their own way, and are ready to go to the battlefield at any time.
