We hope that our field trials will result in positive feedback from the clinical staff. 第 29 屆 IEEE EMIEE 國際程序會議 城市 法國 里昂 2020 年 8 月 23 日至 27 日 應(yīng)用紫蜂技術(shù)將醫(yī)療器械一體化 摘要： 無線電技術(shù)能夠使醫(yī)療設(shè)備，例如生命體征監(jiān)視器，呼吸設(shè)備以及輸液泵做到重要數(shù)據(jù)的收集。 為了獲得這種類型的解決方案，每種設(shè)備必須被匹配到一塊硬件中，做為一個串行的無限網(wǎng)橋即醫(yī)療設(shè)備接口。這是在特別有用的在醫(yī)院的墻壁干擾，和一般人的阻礙下，是一個重要問題。第三個器件參數(shù)，我們選擇的是傳感頻率泵。 三 、 系統(tǒng)架構(gòu) 整個系統(tǒng)的體系結(jié)構(gòu)由一個無線個人網(wǎng)（ WPAN）和局域網(wǎng)組成。在這一點上和 MDI 做一個結(jié)合是可能的。當計時器終止 DLL 的檢索命令的一個字節(jié)數(shù)組的 ASCII 字符的形式。在我們的實驗中，我們成功地檢索呼吸機的數(shù)據(jù)在 5 秒的間隔。 。然后通過定時地發(fā)送 RADAB 和 RADAS 命令我們可以捕捉最新的 信息從呼吸器。當這個計時器終止 DLL 將檢查的現(xiàn)狀已經(jīng)為呼吸機。這是我們使用的為這一項目設(shè)計的協(xié)議。我們捕捉的頻率數(shù)據(jù)被臨床工作人員本身所決定。同樣，我們選擇了一些常見的參數(shù)，生命體征監(jiān)測器。 ZigBee 提供低成本，低功率的設(shè)備，可以互相交流和外面的世界。通過使用設(shè)備的部分無線電傳感器網(wǎng)絡(luò)，例如“紫蜂”技術(shù)網(wǎng)絡(luò)技術(shù)，可以包含更多的優(yōu)點：電纜更換，移動性和位置管理。s selfforming and selfhealing meshwork architecture lets data and control messages pass from one node to another by multiple paths. This is particularly useful in a hospital environment where interference from walls, people and general obstacles is a major issue. Zigbee is based upon the IEEE standard [11] for radio hardware and software specification. Mobility Zigbee enabled devices support a sleep mode. An offline node can connect to a work in about 30 ms .Waking up a sleeping node takes about 15 ms, as does accessing a channel andtransmitting data. If the requirement is to collect data once a minute the device can be placed in a power saving mode saving significant amounts of energy and increasing the battery life. In sleep mode a Zigbee chip can assume as little as [12]. This is particularly important in a medical setting where patients are often on the move while still attached to medical devices. Coexistence Both Zigbee and operate in the licensefree industrial scientific medical (ISM) frequency is already in widespread use within hospitals which would encourage the adoption of Zigbee solutions in the same environment. However care has to be taken to avoid interference between these 2 neighbouring technologies as described in the paper entitled “Coexistance of with other systems in the ” [13]. By selecting an appropriate channel, after performing a simple site survey, these problems can be easily avoided. Device Parameters Typical readings available on a ventilator are Inspiratory Tidal Volume, Expiratory Tidal Volume, O2 concentration, Respiratory Rate, Peak Pressure, Expired Minute Volume and Mean Airway Pressure. The settings on the ventilator are also of interest to medical staff. The most typical settings we’ve chosen are Inspiratory Tidal Volume, Minute Volume, O2 Concentration, I:E Ratio, Breath Duration and Inspiratory Flow. Similarly we have chosen some mon parameters for Vital Signs Monitors. These are Respiratory Rate, Non Invasive Blood Pressure, SPO2 and Temperature. The third device we selected parameters for is the Unfusion Pump. The mon parameters we are most interested in here are Volume, Time, Ramp and Occlusion Pressure. Further parameters can be easily added to the system in the future. Bandwidth For development purposes we analysis a Maquet ServoI [14] which supports all the ventilator parameters described above. This ventilator works in a mand response manner. When initial configuration has taken place 2 mands which are 7 bytes long each will produce 2 responses of 67 bytes each. Therefore even in a multi hop mesh work it is anticipated we would be able to support several of these devices plus other types of devices on the same channel. Scalability The ventilator, having the most parameters of the devices studied, requires the most bandwidth. Experiments carried out on a CSI Vital Signs Monitor [15] show that 44 bytes of data will produce all the information we are interested in. A Braun Infusion Pump [16] exports 24 bytes of data to produce the 4 parameters we need. For any of the medical devices we are concerned with, the readings are typically only required once a minute in a hospital environment. All these devices have their own alarm mechanisms built in。這些設(shè)備經(jīng)常是被
