Integrated implantation assembly of implantable biosensor

Abstract

The relative movement of each component is divided into three stages: (1) an anti-triggering sleeve is removed, the bottom surface of a protective shell is fixed, a main shell is pressed, and the main shell drives a needle-carrying piece, a compression spring, a main sliding seat and a fixed seat to move relative to the protective shell; the emitter of the sensor assembly arranged at the bottom of the fixed seat and the sensor assembly arranged in the protective shell are clamped and assembled, the emitter with the sensor assembly is formed, and the needle carrying piece clamps the needle seat end face of the needle assisting piece through an inner clamping jaw; (2) implanting a sensor electrode of the sensor assembly under the skin by using an implanting needle of the needle assisting piece; thirdly, the outer hanging arm is pushed out of the first sliding groove through the protruding bone position, the compression spring is released, the compression spring pushes the needle carrying piece to move in the direction away from the bottom face of the main sliding base, and the needle carrying piece drives the needle assisting piece to complete needle withdrawing. The power consumption of shelf time is avoided, and the service life of the implantable biosensor is ensured.

Description

technical field [0001] The invention relates to the technical field of biosensors, in particular to an integrated implantable component of an implantable biosensor. Background technique [0002] For the diabetic group, the traditional fingertip blood glucose meter has shortcomings such as invasiveness, limited information, and inability to reflect blood sugar fluctuations and early warnings, which can no longer meet the needs of some people, especially Type 1 that has real-time transmission requirements for blood sugar fluctuations It is of great significance for patients with diabetes and those with type 2 diabetes who require intensive insulin therapy. [0003] Due to the need for continuous blood glucose monitoring, the integrated implant components and internal components of the implantable biosensor need to be used to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration between tissue fluids is a continuous monitor...

Problems solved by technology

[0002] For diabetics, traditional fingertip blood glucose meters have shortcomings such as invasiveness, limited information, and inability to reflect blood sugar fluctuations and early warnings, which cannot meet the needs of some people. The demand, especially for type 1 diabetic patients who require real-time transmission of blood sugar fluctuations and type 2 diabetic patients who require intensive insulin therapy is of great significance

[0003] Due to the need for continuous blood glucose monitoring, it is necessary to use the integrated implant components and internal components of the implantable biosensor to implant the sensor into the subcutaneous tissue of the human body. Measuring the blood glucose concentration in interstitial fluid is a continuous monitoring method available in reality. Its The 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, this type of implant device on the market has complex user operations, long implantation process, The push device is easy to trigger by mistake and other problems, which leads to the reduction of user compliance (compliance, Patient compliance / Treatment compliance, also known as compliance, compliance, refers to the patient's treatment according to the doctor's prescription, consistent with the doctor's order, it is customary to call the patient "cooperation" ; otherwise, it is called non-adherence) and experience

[0004]The transmitter (the device used to transmit the detected biological signal) is small in size and helps to improve the wearing experience. In the current integrated product, the transmitter is placed When entering the interior of the injector, it is in a working or silent state, but no matter which way the transmitter and the sensor component have been electrically connected, in the small 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 in order to meet the requirements of the shelf life of the product (shelf life, Shelf-life, also known as the shelf life, or the validity period of the package, which is the guarantee and commitment to the quality and efficacy of the commodity circulation period) requirements
