Improve data access and software upgrade capabilities of medical care and disease monitoring equipment
Electronic enthusiasts news : Disease monitoring equipment is usually used to measure patients' vital signs, such as blood pressure, heart rate and other parameters. The requirements for managing these important data far exceed the scope of simple inventory control. The equipment needs to provide equipment inspection, calibration and Self-examination results, with a safety upgrade function, while reducing equipment downtime to the greatest extent. Maintenance personnel often attach labels that record maintenance information to the device. Due to the large amount of information 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, disease monitoring equipment usually requires software upgrades. Unlike static label stickers, the dynamic dual-interface RFID EEPROM electronic label solution can record measurement parameters for future reading, and can also log new data into the system, such as calibration constants and inspection information, without the need for any external connection Connector. Dual-interface electronic tags can be connected to disease monitoring devices through the I2C interface. When the device is being executed, the device can read and write electronic tags through the I2C interface. Even if the disease monitoring equipment is not working, medical personnel can read and write the data of the electronic label through a common electronic label reader that complies with 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, and the dual interface storage Make 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 disease monitoring systems Disease 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 challenging, 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 methods and the amount of data are rapidly increasing. This is where a dual-interface RFID solution comes into play. As a gateway to the internal workings of 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 instantly monitors vital signs and activities of patients with chronic diseases, and stores and forwards measurement data or alarms. • Mobile aggregator: a smartphone-like device with or without an external sensor that can report the patient's status through mobile wireless technology. • Wearable healthcare equipment: a healthcare equipment worn on the wrist / arm / chest or a sensor embedded in the fabric of shoes and shirts, used to detect heart rate, breathing, pace and other vital activity characteristics. • Remote patient management (RPM) equipment: special monitoring equipment with built-in patient-specific sensors. These systems are equipped with sensors customized specifically 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 disease 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 equipment failure will have a great impact on the results of the disease detection report. There is no doubt that among the problems that have plagued the industry for many years, the backup battery failure of monitoring equipment has always been at the top of the list. The system self-detects that there is 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 devices are the fastest growing market, and the interoperability standard has not really become the focus of attention until recently. For example, recently, the Continua Health Alliance designated four main interoperability interfaces: USB, Bluetooth, Bluetooth Low Energy (BTLE), and ZigBee. What these four interface technologies have in common is that the monitoring device must be powered on and executed (that is, perform the monitoring function) in order to report a fault through these interfaces and indicate that the device is working properly. When these devices are turned off, the monitor and the error message are usually disconnected, thereby increasing 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 end. Read and write related information Mastering readable and reliable traceable product information and understanding all product information from the production line to the working state is very useful for managing and executing 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 affixed these labels to related products. Basic information required for equipment information traceability. Today's systems require data such as configuration options, calibration constants for multiple sensors, and maintenance intervals. Some systems also provide user-programmable "hot keys" to allow users to set and lock these functions. Only equipment maintenance and management requires so much data, not to mention the real-time data of "check engine status indicator". The ability to record and read error events in real time can greatly reduce equipment maintenance costs and reduce maintenance time. By connecting an electronic label to each device through the I2C interface, medical staff can record and read error events in real time.

Such products are the most common oil-type heater in the market. Electric heating heater, also known as "oil-filled heater", a popular safe and reliable space heater, which is mainly by the sealed electric components, metal heat pipe or heat sink, temperature control components, lights and other components. The heater is filled with YD series of new type of heat transfer oil. Its structure is to install the electric heating tube with a number of heat sink under the cavity, in the cavity around the electric tube filled with heat transfer oil. When the power is turned on, the heat transfer oil around the heating tube is heated to the upper part of the cavity, circulated along the heat pipe or heat sink, and the heat is radiated through the surface of the cavity wall to heat the space environment and achieve the purpose of heating. Then, the air-cooled heat-conducting oil is lowered to the periphery of the heating tube and heated again to start a new cycle. This heater is usually equipped with bimetallic temperature control components, when the oil temperature reaches the set temperature, the temperature control components to disconnect their own power. Electric oil heater heater surface temperature is low, generally not more than 85 ℃, even if the human body will not cause burns.
