Sterilizer Data Logger with Multi-Protocol Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sterilizer data capture and transmission are hindered by noise from printers, continuous ink and paper requirements, and incompatibility across different sterilizer models due to varying data transmission protocols, limiting the usability of data receiving elements.
Innovation Solution
A data logger device configured to fit into the sterilizer's printer space, capable of receiving and logging data from sterilizers using multiple protocols (TTL and RS-232) and storing it on internal or external storage, allowing for network communication and user-friendly interface for data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a printer is used to output sterilizer data, then data can be physically printed, but noise is generated and continuous purchases of paper and ink are required
Solution Approach 1:
The patent removes the printing function from the sterilizer system and extracts data capture to a separate, quiet data logger device. The data logger receives sterilization data via serial communication and stores it on removable memory cards, eliminating the noisy printer while preserving data output capability.
Solution Approach 2:
Instead of printing physical copies of data, the system creates digital copies by storing sterilization data on removable memory cards (SD cards, USB drives). This digital copying approach eliminates the need for physical printing while maintaining data accessibility and backup.
2Loss of information
If a printer is used to output sterilizer data, then data can be physically printed, but downtime occurs due to loading paper and ink
Solution Approach 1:
The patent extracts the data storage function from the printer system and implements it through a separate data logger with removable memory cards. This allows data to be captured and stored without requiring continuous paper and ink supplies, eliminating downtime associated with reloading consumables.
Solution Approach 2:
The data logger automatically captures and stores sterilization data on removable memory cards without requiring manual intervention for loading paper or ink. The system serves itself by continuously recording data on the memory card, eliminating downtime related to manual consumable replacement.
3Loss of information
If a printer is used to output sterilizer data, then data can be physically printed, but physical output may be lost or damaged
Solution Approach 1:
The patent creates digital copies of sterilization data by storing them on removable memory cards rather than relying on physical printouts. This digital copying approach enhances reliability by protecting data from physical damage, loss, or degradation while maintaining easy accessibility for review and verification.
4Reliability
If data receiving elements use specific transmission protocols, then communication with particular sterilizers is achieved, but compatibility across multiple sterilizer models is limited
Solution Approach 1:
The data logger is designed with multi-protocol capability, incorporating both RS-232 and TTL serial communication interfaces. This universal design allows a single data logger unit to communicate with multiple sterilizer models using different protocols, eliminating the need for model-specific receiving elements while maintaining reliable communication with each sterilizer type.
Data Source
AI summary
A data logger for collecting, storing, and transferring data received from a sterilizer is described herein. The data logger is sized and shaped to fit into a slot or opening defined by the sterilizer and previously used for receiving a printing device to output sterilizer data on a printer ribbon. The data logger includes a circuit to facilitate receiving data formatted to conform to at least two different transmission protocols (e.g. RS-232 serial data transmission protocol or TTL serial data transmission protocol). The circuit allows the data logger to be used with different styles of sterilizers and thus increases the set of viable sterilizers. The data logger includes at least one memory device for storing the logged data. This memory device may be a removable component. The data logger may also include a port or connector element for a second memory device such as a USB stick. The data logger may be configured to transfer the logged data to the USB stuck upon insertion or detection of the USB stick in the port.
