Release date: 2006-10-27 China's successful development of a new closed-loop non-invasive insulin pump integrated system A new closed-loop non-invasive insulin pump integrated system was successfully developed by Huazhong University of Science and Technology, Institute of Electronics of Chinese Academy of Sciences and Jilin University, and passed the national 863 project expert group acceptance.
Rheumatoid arthritis (RA) is a chronic, etiology of inflammatory synovitis-based systemic disease. It is characterized by hand, small joints of the joints, symmetry, invasive joint inflammation, often associated with external organ involvement and serum rheumatoid factor positive, can lead to joint deformity and loss of function. According to statistics, the incidence of rheumatoid arthritis in women is 2 to 3 times that of men.It can occur at any age, high incidence of age 40 to 60 years old. People who has rheumatoid arthritis in the late, severe or long-term bedridden patients, due to combined infection, gastrointestinal bleeding, heart, lung or kidney disease can be crisis to life. The main purpose of treatment for Rheumatoid arthritis is to reduce the inflammation of the joints, inhibit the development of lesions and irreversible bone destruction, as far as possible to protect the function of joints and muscles, and ultimately achieve complete disease remission or low disease activity target. Treatment principles include 1. Patient education, 2. General treatment 3. Drug treatment 4. Immune purification 5. Functional exercise 6. Surgical treatment. Anti-Rheumatoid Arthritis drug treatment mainly includes non-steroidal anti-inflammatory drugs, slow-acting anti-rheumatic drugs, immunosuppressive agents, immune and biological agents and botanicals. Over the past decade, the treatment of extra-articular lesions and the emergence of new therapies, so that the efficacy of rheumatoid arthritis has been significantly improved. Most patients with rheumatoid arthritis can get a good control or even complete remission.

The detector consists of a wearable non-invasive blood glucose meter, a miniature piezoelectric pump and a hollow microneedle array, which can be worn on the wrist and is a matchbox size. The test result is sent to the insulin pump hanging at the waist through the wireless module to guide the patient to perform painless injection of insulin through the micro silicon needle attached to the belly. The National 863 Program Expert Group agreed that the main technical indicators of the insulin pump principle prototype developed by the research group of "insulin pump based on MEMS technology" have met the requirements.
The insulin pump can individually set a continuous basic infusion volume and pre-meal high dose according to the change rule of blood sugar to simulate the human physiological insulin secretion machine. After the insulin pump has set the procedure, it can be continuously continuous within 24 hours. Inject a small amount of short-acting insulin. This mode of action of the insulin pump is like a normal pancreas, so it is also called artificial islets. Shanghai Medical Devices
