Gamma hardened pharmaceutical devices
View Patent ↗A system and method for implementing embedded electronics in environments where radiation or extreme temperatures are used is disclosed. Embedded electronics are affixed to various components of a pharmaceutical system, thereby enabling the customer to download pertinent information about the component, such as lot number, date of manufacturer, test parameters, etc. Additionally, these electronics allow an array of functions and features to be implemented, such as integrity tests and diagnostics. The electronics in the pharmaceutical components utilize a technology that is not as susceptible to radiation and extreme temperatures as traditional electronics.
1. A method of creating a sterile component, having embedded electronics, comprising:
manufacturing an electronic device using Silicon on Insulator (SOI) technology;
affixing said electronic device to said component;
sterilizing said component by subjecting said component to gamma or beta radiation;
attaching a heater near said electronic device, wherein said heater comprises a coil oriented around said electronic device; and
reconditioning said electronic device after exposure to said radiation by activating said heater.
2. The method of claim 1 , wherein said component is selected from the group consisting of filters, bags, tubes and process instruments.
3. The method of claim 1 , wherein said electronic device comprises wireless communication means.
4. The method of claim 3 , wherein said means comprises RFID.
5. The method of claim 3 , wherein said means comprises the communication protocol described in IEEE 802.15.4.
6. The method of claim 3 , wherein said means comprises the communication protocol described in IEEE 802.15.1.
7. The method of claim 1 , wherein said electronic device is a sensor adapted to convert a physical characteristic to an electric signal, selected from the group consisting of fluid condition sensors, including pressure sensors, temperature sensors, and flow rate sensors, and fluid component sensors, including chemical sensors and concentration sensors.
8. The method of claim 7 , wherein said sensor comprises a sensor head, and said sensor head is manufactured using SOI technology.
9. The method of claim 7 , wherein said sensor comprises a signal processing unit, and said signal processing unit is manufactured using SOI technology.
10. The method of claim 1 , wherein said radiation is transmitted substantially along one direction, and said electronic device is oriented so as not to maximize its surface area exposed to said radiation.
