Separately powered dynamic blood sugar monitoring transmitter, system and signal sampling method

Abstract

The invention discloses a separately powered dynamic blood sugar monitoring transmitter, a system and a signal sampling method. The separately powered dynamic blood sugar monitoring transmitter structurally comprises a transmitter body and a sensor base device. The sensor base device is divided into a base and adhesive tape, a battery jar and a groove are formed in the base, a battery is arrangedin the battery jar, a rotating seat is installed in the groove, one side of the rotating seat is hinged in the groove, a silica gel seat is arranged in the rotating seat, a pair of conductive rubbersis arranged in the silica gel seat, the transmitter body comprises a circuit board assembly, and the circuit board assembly is provided with four conductive pins which can be in contact with a positive electrode, a negative electrode and the two conductive rubbers. Compared with the prior art, the button battery can be separated from the transmitter body and integrated with a sensor, when the transmitter is not used, the transmitter is not installed on a sensor base, so that the transmitter is in a power-off state, power of the button battery is not consumed; when the transmitter is used, thetransmitter is buckled on the sensor base, and the battery on the sensor base is electrically connected to the transmitter for power supply.

Description

technical field [0001] The invention relates to a dynamic blood glucose monitoring transmitter with separate power supply, a system and a signal sampling method, and belongs to the technical field of wearable medical devices. Background technique [0002] The traditional blood glucose transmitter is mainly composed of three parts, a button battery, a circuit board and a plastic casing. Due to waterproof requirements and volume limitations, the button battery and the circuit board are generally placed in the transmitter together, and the two are usually molded together, so the transmitter battery cannot be replaced, and the use time of the disposable sensor is generally 3-14 days. , will be discarded after use. When the battery life is used up, the transmitter is basically unusable. From the perspective of cost, the cost of the transmitter's plastic casing and circuit board is much greater than the cost of the battery, and the life of the transmitter's plastic casing and cir...

Problems solved by technology

[0006] In addition, the dynamic blood glucose transmitter calculates the blood glucose concentration by sampling the current value of the sensor, so the accuracy of the sampled sensor directly affects the accuracy of the calculated blood glucose concentration, and the wireless SOC module generally has a built-in ADC sampling circuit, and the accuracy of this circuit is usually marked as It is called about 10 to 12 digits, and the effective precision may be slightly lower than the nominal value

If higher accuracy is required, an expensive external ADC circuit needs to be added
