Patient monitoring equipment is usually used to measure the patient's vital signs, such as blood pressure, heart rate and other parameters. The requirements for managing these important data are far beyond the scope of simple inventory control. The equipment needs to provide equipment inspection, calibration and self-test results , And has a safety upgrade function, while minimizing equipment downtime. Maintenance personnel often stick labels that record maintenance data on the device. Due to the large amount of data that needs to be recorded, the labels are gradually damaged after a period of time. Label stickers are no longer a reasonable choice. With the rapid development of technology, patient monitoring equipment usually requires software upgrades.

Unlike static label stickers, the dynamic dual-interface RFID EEPROM electronic label solution can record measurement parameters for later reading, and can also input new data into the system, such as calibration constants and inspection information, without the need for any external connection Connector. The dual-interface electronic tag can be connected to the patient monitoring device through the I2C interface. When the device is running, the device can read and write the electronic tag through the I2C interface. Even if the patient monitoring equipment is not working, medical staff can read and write the data of the electronic label through a common electronic label reader that conforms to the ISO 15693 13.56 MHz RFID standard, because it can ensure that the data is up to date, safe, and read and write at any time, dual interface The memory makes the RFID technology chain more perfect.

The target applications of the dual-interface passive RFID system include equipment maintenance conditions and records, authorized accessory verification, sensors, counterfeit product identification, disposable product reuse control, and the addition of new authorized products. When the monitoring device is working or in standby, the operator can read and write the data in the dual interface RFID through the monitoring device. When the device is turned off, the operator can use the electronic tag reader to manage the data in the dual interface RFID. This big advantage is Designers create more opportunities.

Classification of patient monitoring system

Patient monitoring systems are generally divided into three categories: bedside monitors, portable handheld monitors, and body-worn monitors.

Bedside monitors play an important role in providing medical monitoring and diagnostic information. Among the monitoring information required by healthcare professionals, the information provided by bedside monitors is becoming an increasing proportion. Bedside monitoring equipment is usually installed in important intensive care monitoring areas, such as intensive care units. At present, most bedside monitoring equipment can be connected to the central monitoring system through the hospital network and exchange data through the facility network.

The management of portable monitors is no small challenge, because such devices seem to be able to "leave the group or even get lost". Although checking the location of the device is beyond the scope of this article, knowing what happened to the device is very helpful to ensure that the device continues to meet the standard and verify the identity of the device owner.

Although the body-worn monitor is not a new invention, but with the upgrading of products, the measurement method and data volume are rapidly increasing. This is where a dual-interface RFID solution comes into play. As a gateway to work inside the system, the dual-interface RFID solution is connected to the monitoring equipment without tangled cables, so it can improve the practicality and service life of the monitor.

The body-worn monitor can also be divided into the following categories:

● Mobile / wearable personal monitor (MPM): wearable personal monitoring equipment monitors the vital characteristics of patients with chronic diseases in real time, and stores and forwards measurement data or alarms.

● Mobile aggregator: a smartphone-like device with or without external sensors that can report the patient's status through mobile wireless technology.

● Wearable health equipment: health equipment worn on the wrist / arm / chest or sensors embedded in the fabric of shoes and shirts, used to detect heart rate, breathing, pace and other life activity characteristics.

● Remote patient management (RPM) equipment: special monitoring equipment with built-in patient special sensors. These systems are equipped with sensors customized for patients by the hospital, and can report all vital signs parameters, such as heart rate, patient's posture (standing or lying down).

Whether it is a bedside monitor, or a portable or wearable monitor, all patient monitoring equipment faces a common challenge: how to keep the equipment up-to-date with software, calibration data or maintenance records? How to find faulty equipment?

Benefits of managing system data

A simple device failure will have a great impact on the results of the patient test report. Not surprisingly, among the problems that have plagued the industry for many years, the backup battery failure of the monitoring equipment has always been at the top of the list. The system self-test has no alarm when the alarm occurs, but alarms when it should not. For bedside monitoring equipment, the central monitoring function can report faults and send maintenance personnel to eliminate the faults, thereby avoiding serious problems.

Portable and body-worn monitoring devices present designers with a series of more challenging issues. One of the problems is that these two major devices are the fastest growing markets, and interoperability standards have not really become the focus of attention until recently. For example, recently, the Continua Health Alliance designated four major interoperability interfaces: USB, Bluetooth, Bluetooth Low Energy (BTLE), and ZigBee. What these four interface technologies have in common is that the monitoring equipment must be powered on and running (that is, perform the monitoring function) in order to report faults through these interfaces and indicate that the equipment is working properly. When these devices are turned off, the monitor is usually disconnected from the error message, which increases the difficulty of reducing or even finding any problems.

Portable and body-worn monitoring devices have another emerging challenge. In order to be waterproof and dustproof, it is easy to clean and will not damage electronic components. Today's portable and body-worn monitoring devices all use an integrally sealed design In this case, adding a connector or adding a function to the connector will inevitably increase the volume, cost, or system complexity of the sensor port.

Read and write related data

Mastering readable and reliable traceable product information data and understanding all product information from production line to working status are very useful for managing and operating these assets (monitoring equipment). For a long time, equipment manufacturers have concisely described the product manufacturing date, revision, production line / factory, serial number and other product information on the label stickers with codes, and then pasted these labels on related products. Basic information required for traceability with equipment information.

Today's systems require data such as option configurations, multiple sensor calibration constants, and maintenance intervals. Some systems also provide user-programmable "hot keys" that allow users to set and lock these functions. Only so much data is required for equipment maintenance and management, let alone real-time data for "check engine status indicator". Being able to record and read error events in real time can greatly reduce equipment maintenance costs and reduce maintenance time.

By connecting an electronic tag to each device through the I2C interface, medical personnel can record and read error events in real time.

Dual interface memory flexible and versatile

According to memory requirements, these dual-interface memory chips can be divided into multiple logical storage areas, sharing the same I2C compatible bus and antenna. This solution not only expands the application range of memory, but designers can also set a 32-secure password in the memory or any logical area to establish a memory access authority mechanism.


Dual interface

The simplicity of the design allows designers to flexibly apply this dual-interface electronic tag. Now you may want to ask, what happens if the device receives system commands while reading and writing electronic tags? Most engineers know that designing a simple system usually transfers the complexity to the chip. For example, in ST's M24LR64 dual-interface RFID EEPROM chip, there is such a circuit that can handle parallel communications that may occur and drive system activities from the RF and I2C sides.
