Description

Technical Field

[0001] The present invention relates to the technical field of biological information monitoring, and in particular to a low-power implantable biological information monitoring device set. Background Art

[0002] For the diabetic population, traditional fingertip blood glucose meters have shortcomings such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations and provide warnings. They can no longer meet the needs of some people, especially type 1 diabetes patients who have real-time transmission requirements for blood glucose fluctuations and type 2 diabetes patients who require intensive insulin treatment.

[0003] Due to the need for continuous blood glucose monitoring, an integrated implantable biosensor component is required to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in the tissue fluid is a practical continuous monitoring method. Its single service life is one to two weeks, which greatly reduces the pain caused by continuous fingertip blood drawing and venous blood drawing.

[0004] In the prior art, the transmitter (device for transmitting monitored biological signals) has a compact structure and volume, which helps to improve the wearing experience. In the current integrated products, the transmitter is in working or silent state when placed inside the transmitter. However, no matter which of the above methods is used, the transmitter and the sensor assembly have been electrically connected. In the smaller size of the transmitter, the battery capacity is not large due to the limited size of the battery. The hardware needs to have extremely low power consumption to meet the shelf life requirements of the product. In the current integrated products, the transmitter and the implantable sensing electrode are integrated. After production, they need to be disinfected and sterilized before being implanted into the human body. Disinfection and sterilization require a relatively large packaging box, which occupies a large space and is costly.

[0005] In the prior art, the implantable biosensor assembly and the main control circuit of the transmitter are connected in an integrated manner. After use, the implantable biosensor assembly is discarded along with the main control circuit, resulting in huge waste. Summary of the invention

[0122] For the diabetic population, traditional fingertip blood glucose meters have shortcomings such as being invasive, having limited information, and being unable to reflect blood glucose fluctuations and provide warnings. They can no longer meet the needs of some people, such as those who are pain-sensitive, especially type 1 diabetes patients who have real-time transmission requirements for blood glucose fluctuations and type 2 diabetes patients who require intensive insulin treatment.

[0123] Due to the need for continuous blood glucose monitoring, an implantable biosensor implant is required to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in the tissue fluid is a practical continuous monitoring method. Its single service life is one to two weeks, which greatly reduces the pain caused by the process of continuous fingertip blood collection and venous blood collection. Currently, such implant devices on the market have problems such as complex user operation, long implantation process, and easy false triggering of the push device (used to implant the transmitter component), which leads to reduced user compliance and experience.

[0124] The compact structure of the transmitter component helps to improve the wearing experience. In current conventional integrated products, the transmitter component is in working or silent state when placed inside the needle aid (main shell). However, no matter which of the above methods is used, the transmitter and the sensor have been electrically connected. In the smaller size of the transmitter, the battery size is limited, resulting in a small battery capacity. The hardware needs to have extremely low power consumption to meet the shelf life requirements of the product.

[0125] Implantable biosensors are generally disposable sterile consumables that need to be sterilized before use. Conventional sterilized packaging is large in size, has a complex assembly process, and is costly. Therefore, how to conveniently and cost-effectively construct sterilized packaging has become an urgent research direction for all parties; the technical solution provided by the present invention solves this problem.

[0126] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
