Problems solved by technology

The biggest shortcoming of the invasive measurement method is that it cannot realize the dynamic detection of the blood glucose concentration of the human body, and cannot obtain the real-time changes of the blood glucose concentration of the patient, which is unfavorable for the effective treatment of diabetes
[0004] In order to realize the dynamic and continuous detection of blood glucose concentration, non-invasive methods of in vitro optical detection and minimally invasive methods of transdermal extraction to detect glucose concentration in interstitial fluid have appeared, but these detection methods have problems such as insufficient detection accuracy and low reliability. , still in the research stage, with little clinical application

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] refer to figure 1 As shown, it includes two parts: the implanted component in the body and the component in vitro.

[0020] The implanted components in the body include an implantable glucose sensor 1, a signal processing circuit 2, a microprocessor 3, a first wireless communication module 4, a power supply module 5 and a housing 6, and the implantable glucose sensor 1 is compatible with human tissue fluid or Blood contact converts the glucose concentration signal in the interstitial fluid or blood into an electrical signal, the signal processing circuit 2 is connected to the implantable glucose sensor 1, and amplifies the electrical signal output by the implantable glucose sensor 1, Operations such as filtering and analog-to-digital conversion are converted into digital signals and then input to the microprocessor 3. The mic...

Description

technical field [0001] The invention belongs to the technical field of biochemical detection and implanted medical instruments, and in particular relates to an implanted low-power wireless blood glucose monitor. Background technique [0002] Diabetes is an endocrine and metabolic disorder caused by insulin deficiency. The early symptoms are loss of control over blood sugar concentration, which then leads to a series of syndromes (blindness, renal failure, etc.), and even endangers the patient's life. Diabetes is a worldwide frequently-occurring and common disease, and its incidence has shown an obvious upward trend in recent years. The incidence rate in my country has reached 2.5-3%, which is very close to 2-5% in developed countries in Europe and America. Today, there are about 50 million patients in my country and more than 200 million patients in the world. Diabetes has become a global health care problem and seriously threatens human health. It has become the third larg...
