Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to an indwelling unit for monitoring.
Background
When a patient with symptoms such as diabetes needs to monitor various indexes in blood, a monitoring sensor needs to be implanted subcutaneously, and the monitoring sensor is disposed on an indwelling unit which is placed on the skin of the patient.
Devices implanted subcutaneously or positioned on the skin are required to be sterile when inserted, and for index analysis monitoring systems, where the indwelling unit has integrated thereon a sensor for monitoring and associated electronics connected to the sensor. But the sterilization environment required for the monitoring sensor and the related electronic components is different based on the performance and structural difference of the two.
Specifically, the surface of the sensor for monitoring various indexes in blood is provided with a special material with biological activity, and strict requirements are imposed on temperature, humidity and the like. While the traditional medical instrument is sterilized by using ethylene oxide, the ethylene oxide sterilization mode can damage active substances on the surface of the sensor, and is not suitable for sterilization of the sensor for monitoring. Therefore, a sterilization method using radiation sterilization is required for the monitoring sensor.
However, the radiation sterilization mode can damage other electronic components connected with the sensor, and the other electronic components still need to be sterilized by adopting the traditional ethylene oxide.
Therefore, it is necessary to sterilize the monitoring sensor portion and the other electronic component portion separately by different sterilization methods.
Chinese patent publication No. CN112423665A discloses a focused sterilization and sterilized subassembly for an analyte detection system. The patent provides two technical concepts, one of which is a two-piece architecture system, such as the sensor tray 202 shown in fig. 2A and the sensor applicator 102 shown in fig. 2B in CN112423665A, provided to the user as separate packages. In this structure, although the sensor part can be sterilized by radiation alone, the user needs to open two packages and assemble them at the time of final use, thus increasing the difficulty of use by the user, the convenience is poor, and in the assembling process, the packaging box serving as a sterile barrier has lost the effect of the sterile barrier after tearing the packages, and if the user does not assemble them in time, the exposed sensor and the application part have the risk of infecting bacteria and viruses.
The second technical concept provided by the above patent provides a one-piece architecture shown in fig. 1 in CN112423665A, which contains sterilization techniques specifically designed for one-piece architecture. In contrast to the first two-piece architecture, the single sealed package does not require any user assembly steps. However, the sterilization technology specially designed for the one-piece architecture is complex, the cost is high, and the sensor and the electronic component are in the one-piece architecture, but the electronic component is isolated when the sensor is sterilized by radiation, so that the structural complexity is obviously increased, and the sterilization technology is high.
Although two structural forms of architecture systems are shown in CN112423665A, the two structural forms are used for sterilizing the sensor and other electronic components separately. However, the two architecture systems described above have in common that in the indwelling unit, the component configuring the sensor and the component configuring the other electronic components are longitudinally overlapped in the axial direction, which results in a thicker indwelling unit. Under the condition that the thickness of the retaining unit is thicker, the comfort of a user is poor, the probability of touching the retaining unit without difference is also larger, and certain inconvenience is caused to the user.
