Description

Self-describing protocol conversion device Technical Field The subject matter of the present disclosure relates generally to devices for updating data in medical monitoring or therapy systems. More specifically, described herein is a device that allows a non-native device or a non-self-describing protocol device to operate as an advanced self-describing device and connect to a multi-function medical device. Background Conventional models for interfacing patient physiological sensors to medical devices employ software specifically designed to handle data from a particular sensor and report values to a medical device (such as a patient monitor) programmed to receive and display data from a particular sensor type. However, these conventional models introduce limitations that need to be addressed. One problem is that it is difficult to add the ability to use new parameters without updating the software on the medical device, as the medical device must have a specific ability to handle the new parameters. Additionally, since both parameters and software in the medical device are updated together, they are also tested as a system and released as a system. Furthermore, the new version of the software may be incompatible with previously released medical devices at the customer location. Furthermore, the medical device may not be able to handle data from other sensor device types than the particular sensor device for which it is specifically programmed, or may use a different data/communication protocol than that used by the particular sensor, thereby limiting its ability to handle or otherwise process data (if any) from the sensor device. Furthermore, the sensor device may not be a self-describing device. Again, this limits the ability of the medical device to handle or otherwise process data (if any) from the sensor device. Thus, in view of many different types of sensor devices and many different types of data/communication protocols, a device that interfaces between the sensor device and the medical device to ensure that the medical device is able to handle or otherwise process data from the sensor device may be desirable. Disclosure of Invention It would be advantageous to provide a device (such as a cable, connector, interface, rack device, etc.) to perform one or more tasks such as transmitting, obtaining, describing, formatting or transmitting data, or a combination(s) thereof, from one or more non-self-describing physiological patient parameter sensors or devices to a multi-functional medical device (such as a patient monitor, medical device, therapeutic device, or other component in a medical monitoring system), and thus not using the self-describing protocol (SDP) for data handling and communication. SDP is a set of rules for conveying and understanding limited types of information using data structures, transport formats, and defined codes so that a receiver of information can use, report, or retransmit the information without requiring a priori characterization of the particular received information. It includes any established SDP and annex to established protocols. Thus, a device configured with an SDP (including handling, generating, and/or processing data in an SDP format) may be referred to herein as an SDP device or a local device, and a non-descriptive device not configured with an SDP for handling, generating, and/or processing data in an SDP format may be referred to herein as a non-SDP (NSDP) device or a non-local device. Such a non-descriptive device may be, for example, but is not limited to, a physiological patient parameter sensor. These non-SDP devices perform one or more tasks, such as transmitting, obtaining data, describing data, formatting data, transmitting data, or a combination(s) thereof, in a communication protocol that is different from the SDP used by the monitoring system. It would therefore be advantageous to provide a method for efficiently and easily representing data received from non-SDP devices as SDP using a structure that allows SDP devices (such as multi-function medical devices) to process the data without prior information about the data or its source, where processing means analyzing, storing, presenting, manipulating, transmitting, or any combination thereof. It would be further advantageous to provide a means for reporting processed or unprocessed data from non-SDP devices to SDP devices on a communication network, which have no prior information about the data or its source. Furthermore, it would be advantageous to provide a device, method or system for a device to describe the information it will transmit to a medical SDP device, rather than relying at least in part on pre-established information or data structures specific to non-SDP devices. The devices, methods, and systems described herein provide at least one or more of the above-described advantages by allowing a non-SDP device to perform one or more tasks, such as transmitting, obtaining, describing, for
