Description

Adjustable emitter device

Technical Field

The utility model belongs to the technical field of continuous monitoring of blood sugar, and particularly relates to an adjustable emitter device.

Background

CGMS generally consists of a GOx-based "needle-type" electrochemical glucose sensor that can be implanted subcutaneously in a human body with minimal trauma, a set of wireless or wired signal detection and transmission/recording devices (transmitters), and a processor (usually placed in an App or receiver) that converts the detected current signal into glucose concentration, often requiring a needle assist device to implant the sensor subcutaneously. The sensor is penetrated into the skin through the needle assisting device, an electric signal is formed when the sensor is oxidized and reacts with glucose in the body in tissue fluid of a patient, the electric signal is converted into a blood glucose reading, and the blood glucose reading is transmitted to the receiver through the transmitter. Under the guidance of the data and the visual chart, a clinician can comprehensively understand the 24-hour blood sugar fluctuation condition of the patient, and can be matched with an insulin pump to inject insulin to the patient when necessary.

Subcutaneous tissue thickness may vary greatly depending on sex, body part and body mass index, and skin thickness is generally measured using the characteristic that red light can penetrate human tissue, and skin thickness is measured using ultrasonic detection waves and ultrasonic echo signals.

CGMS can correctly reflect the change of blood sugar of human body, which is based on the assumption that the concentration of glucose in intercellular fluid is very similar to the concentration of blood sugar, and is basically based on the fact that the glucose in tissue fluid derived from capillary vessels of human body has higher correlation with blood sugar, and the current generated by biochemical reaction of glucose in tissue fluid can be converted into blood sugar detection value by referring to the calibration of blood sugar value. This requires that the sensor be closer to the site of capillary enrichment, with greater accuracy. Since CGMS sensors are usually required to be implanted in the subcutaneous fat layer, the abundance of capillaries varies among individuals due to their physical conditions, the thickness of the fat layer, and the like. Human fat generally has both a white and brown color, of which: white fat accumulates under the skin, responsible for storing excess energy, and also forms unsightly fat proud; the brown fat cell contains a large amount of mitochondria and is rich in capillary vessels, so that a brown fat part or a joint of white fat and brown fat is a recommended implantation part of the CGMS sensor. The adjustment of the implantation depth of the sensor is beneficial to obtaining the maximum effective area of the sensor and ensuring the sensitivity and the accuracy of the sensor.

At present, the length of a flexible sensor probe implanted into the subcutaneous part of a patient in some continuous blood Glucose Monitoring system (CGMS) (continuous Glucose Monitoring System) products at home and abroad is invariable, and the flexible sensor probe is generally implanted into the skin of a human body by 5 mm. However, the thickness of the skin of a human body varies from person to person, and the thickness of the skin varies from person to person, usually 0.5-4mm (excluding the subcutaneous fat layer), so that the depth of the flexible sensor probe implanted into the human body does not necessarily match the thickness of the skin of all users, and the blood sugar monitoring value of some diabetic patients is not accurate enough.
