Description

Analyte detection device mounting unit with sterile barrier Technical Field The present utility model relates generally to the field of medical devices, and more particularly to an analyte sensing device mounting unit with a sterile barrier. Background The pancreas in the body of a normal person can automatically detect the glucose content in the blood of the person and automatically secrete the required insulin/glucagon. However, the pancreas of the diabetic patient has abnormal functions and cannot normally secrete insulin required by the human body. Diabetes is a metabolic disease caused by abnormal pancreatic function of a human body, and diabetes is a life-long disease. At present, the medical technology cannot radically cure diabetes, and the occurrence and development of diabetes and complications thereof can only be controlled by stabilizing blood sugar. Diabetics need to test blood glucose before injecting insulin into the body. Most of the current detection means can continuously detect blood sugar and send blood sugar data to external equipment in real time, so that the blood sugar data is convenient for a user to check, and the detection method is called continuous glucose detection (Continuous Glucose Monitoring, CGM). The method needs to attach the detection device to the skin surface, and the sensor carried by the detection device is penetrated into subcutaneous tissue fluid by an installer to complete detection. For subcutaneous devices, it is important to maintain sterility when pricked subcutaneously, otherwise serious damage to the health of the user, and even safety issues, may occur. The current sterilization mode mainly comprises gas sterilization and radiation sterilization, and adopts gas sterilization, such as ethylene oxide gas sterilization, because biological enzyme on a sensor can react with gases such as ethylene oxide and the like to influence the activity of the biological enzyme, and further influence the monitoring accuracy, electronic elements of the sensor can be damaged when large-area radiation sterilization is adopted, a complex shielding system is required to be arranged in an analyte detection system, and when the directional sterilization is carried out on a part penetrating into the skin, other parts in a shell of an installation unit are not sterilized, so that the part penetrating into the skin still carries the risk of bacteria again after sterilization. Accordingly, there is a need in the art for an analyte sensing device mounting element that prevents the subcutaneous portion from re-carrying pathogens after sterilization. Disclosure of utility model The utility model discloses an analyte detection device mounting unit with a sterile barrier, wherein before mounting, a penetrating subcutaneous part of an auxiliary needle is accommodated in a needle accommodating cavity of an outer cover body, and a main sterile barrier is arranged at a contact position of the outer cover body and a first through hole, so that after directional irradiation sterilization is carried out on the penetrating subcutaneous part, the penetrating subcutaneous part is in a closed sterile environment, germs existing in an unsterile part in the mounting unit cannot enter the sterile environment, the penetrating subcutaneous part cannot carry germs again after directional sterilization, the health of a user cannot be influenced, and the use safety of the user is ensured.
