Description

Sensor assembly capable of independently sterilizing

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a sensor assembly capable of being independently sterilized.

Background

Implantable biosensors have the advantage of continuously measuring certain important physiological or pathological parameters in the body over time, such as the concentration of oxygen, glucose, lactic acid, etc., to obtain a comprehensive and accurate diagnostic or therapeutic effect. The method is used for continuously monitoring the physiological parameters of the human body, and has important reference significance for diet, health, medication, exercise conditions and the like. In vitro blood glucose self-monitoring is a typical example, but the monitoring effect is greatly reduced because the user needs to continuously prick the finger to obtain discontinuous test values and remember the test values. Continuous blood glucose monitoring utilizes an implanted blood glucose sensor to monitor blood glucose signals, and then data can be sent to receiving equipment through a transmitter, so that all-weather uninterrupted and visual blood glucose monitoring is realized. Likewise physiological parameters such as lactic acid, uric acid and the like can be monitored by the method.

In medical standards, the part implanted into the human body should be sterile before implantation, and bacteria, fungi and viruses can be eliminated or killed by sterilization, so that the biological load is effectively reduced, and the safety of the user can be ensured. The usual implantation method is to sterilize the sensor alone, implant the sensor only into the body, and then use the sensor in combination with the electronic circuit part. The implantation method not only requires the user to complete the implantation of the sensor, but also requires the user to complete the operation of combining the sensor and the circuit part, has complex operation, and is easy to cause misoperation and pollution and damage of the sensor parts in the process. Thus, how to allow the sensor and electronic circuit parts to be assembled and sterilized prior to implantation is a problem that needs to be addressed in the art. Common means of sterilization for sensors include irradiation sterilization, ethylene oxide sterilization and autoclaving, wherein the application of irradiation sterilization to a sensor comprising electronic components may cause damage to the electronic components, and ethylene oxide sterilization and autoclaving may cause partial or even complete deactivation of the chemicals on the sensor, and thus none of the three sterilization means can be applied to sterilization for sensors comprising electronic circuitry. To solve the sterilization problem, patent 202210465702.1 discloses a sterilization module, medical instrument and implanter containing a monitoring treatment probe, but the sterilization module volume and the emitter are as large as each other, which not only wastes sterilization space and reduces sterilization efficiency, but also requires a large amount of assembly work on the sterilization module after sterilization, which poses a great threat to the safety and reliability of sterilization. Therefore, there is an urgent need to develop a sensor assembly with circuit elements that can be independently sterilized.
