Novel implantation device of implantable biosensor

Abstract

The invention relates to a novel implantation device of an implantable biosensor. The implantation device comprises an implantable biosensor implanter, wherein an implantable sensor fixing device in which a bend-free implantable biosensor is obliquely clamped at the transmission end of the implantable biosensor implanter; and the implantable sensor fixing device is placed on a base, and the base is detachably and fixedly connected with the implantable biosensor implanter. According to the implantation device, the implantable biosensor is pushed into the fixed clamping groove in the base through the implantable biosensor implanter, so that the detection part of the bend-free sensor can be implanted into skin to perform detection, the sensor does not need to be bent after the implantable biosensor is implanted into the skin, and the sensitivity of the sensor is prevented from being influenced by bending, so that the detection effect is more accurate.

Description

technical field [0001] The invention relates to the field of implantable biosensors, in particular to a novel implantable device for implantable biosensors. Background technique [0002] The monitoring of blood sugar is very important for diabetic patients, and the blood sugar value helps to evaluate the glucose metabolism disorder of diabetic patients. At present, blood glucose detection can be divided into in vitro detection after blood collection and real-time detection with implanted blood glucose sensors. When using the method of in vitro detection after blood collection to control blood sugar, blood must be collected multiple times a day, which brings a heavy burden to the patient's spirit and body. Therefore, the method of real-time detection with implantable blood sugar sensors is becoming more and more popular. [0003] At present, the only continuous blood glucose monitoring products that can be used in clinics have been technically verified to a certain extent, o...

For example, the patent document with application number CN201610985667.0 discloses a biosensor electrode elastic implantation device and its use method. It uses a puncture combined sleeve, an elastic mechanism, and a specific force-bearing structure to realize automatic puncture. After the puncture needle exits the silicone seat , the silicone seat follows the rotation of the rotating seat and fits parallel to the bottom surface of the sensor base, so that the sensor is embedded in it; and as disclosed in the patent document of application number CN201310724053. Cooperate with the sensor assembly to implant the electrode into the human body, and at the same time push the sensor mounting seat into the guide seat. After the half-wall needle withdraws, the guide seat rotates and snaps into the implant seat, so that the sensor mounting seat is embedded in it. The above fixing method The problem is that it is necessary to manually press the skin part of the sensor flat, which will bend the electrode part of the sensor, and the electrode part is bonded by layers of multiple electrodes and insulating layers. Due to the different material properties, the original adhesion may be destroyed when bent. The combined structure makes it separate, which affects the monitoring accuracy. At the same time, the above patent documents do not record in detail the waterproofing of the electrode contacts. Once in contact with liquid, a short circuit will occur, so you need to pay attention to waterproofing after wearing
