Data logger

摘要

A data logging module and a method of monitoring a medical warming cabinet is disclosed. A temperature of the heating chamber and a state of a door of the heating chamber are sampled at predetermined intervals and recorded as data packets on a memory device. A display may provide a message when the memory device is reaching capacity. Moreover, a selected of the data packets may be analyzed (such as the data packets excluding the data packets when the door is open) for the generation of a report. The data packets from the memory device may be transferred from the memory device to an external memory device as necessary.

1. A method of monitoring a medical warming cabinet employing a computer and a door sensor, the medical warming cabinet including a heating chamber heated by a heating apparatus, access to the heating chamber provided through a door into the heating chamber, and an electronic temperature monitoring system, the method comprising:
receiving an electrical output from the door sensor at the temperature monitoring system indicating that the door into the heating chamber has been moved from a closed position into an open position; determining a door open time based on receipt of the door open status signal; receiving a temperature value at the temperature monitoring system from a temperature sensor configured to determine a temperature of the heating chamber at a temperature sensing time; recording in a data packet on a memory device the temperature value, the temperature sensing time, and the door open time that is proximate and prior to the temperature sensing time; analyzing a selected plurality of data packets rejecting data packets where the temperature sensing time is within a defined time limit of the door opening time; and generating a report providing temperature information based on at least one temperature value selected according to the temperature sensing time and the door open time wherein temperature values taken within the defined time limit of the door opening time are rejected to preferentially differentiate temperature values taken when the door is closed.
