糖尿病足病室建设综合方案

糖尿病足病室建设综合方案

糖尿病足病诊治中心---------构建及可行及效益分析报告一:构建糖尿病足病诊疗中心的意义及紧迫性糖尿病足病,是糖尿病患者下肢截肢的主要原因。

全球约1.5亿糖尿病患者中,有15%~20%的患者可能在其病程中发生足溃疡或坏疽。

糖尿病足病的截肢率是非糖尿病患者的15倍,美国糖尿病协会(ADA)提供的统计数据显示,在美国每年有86000患者会因糖尿病失去足或下肢而致残。

糖尿病足溃疡的治疗花费巨大,众所周知,足溃疡糖尿病患者的死亡率约是无溃疡糖尿病患者的两倍,DPN相关的足部并发症还会产生巨大的社会经济负担。

约50%的糖尿病足病住院是因为足溃疡,在美国,单个溃疡确诊后连续2年的门诊和住院治疗费用约为28000美圆。

随访显示50%的截肢患者其对侧下肢最终也将被截肢。

截肢相关的费用将高达30000-33500美圆。

糖尿病足的综合治疗费用相当于糖尿病其他方面诊治费用的总和。

糖尿病在我国近10年呈井喷态势,据世界卫生组织统计,目前中国糖尿病患者已经接近2亿。

中心城市的发病率已超过10%。

因周围血管病变和周围神经病变而引起糖尿病足是糖尿病并发症是目前最严重的问题,尤其表现在溃疡坏疽和截肢导致住院和康复时间延长,家庭和社会负担增加等。

糖尿病足并发症是最为严重的和耗费很大的并发症,下肢截肢通常是在足溃疡的基础上发生的,而采取包括预防,患者和义务人员教育,多学科写作处理,足溃疡和密切监测在内的措施可以使溃疡感染率下降49%,截肢率下降85%。

因此,一些国家和组织,例如世界卫生组织和国际糖尿病联盟明确的将截肢率降低至50%作为靶目标。

根据国际糖尿病足工作组的《糖尿病足国际临床指南》,把糖尿病足的宣教、筛查、诊断和治疗作为整体理念,以足病诊疗中心的形式,系统、规范的开展工作、以利于临床中取得很好的效益,是目前国际及国内开展糖尿病诊断治疗的通用形式及标准。

二:糖尿病足病诊疗中心的构建、管理和运作细则1. 完善诊疗中心设备,经医院批准挂牌成立糖尿病足诊疗工作室,负责糖尿病足相关知识的宣教、筛查、诊断、治疗和预防等工作,逐步完善相关设备,设立专门负责人,全面负责策划、组织、管理、实施、评估、研究与持续改进等工作。

The measuring units include vibration acceleration, vibration velocity and vibration displacement. The vibration signal can be evaluated for RMS, peak, peak-peak and crest factor which is shown as the measurement value on the screen. These measurements can be used to detect and identify machine imbalances which can lead to e.g. bearing damage.Apart from a Hold function which freezes the current measurement value, the device also includes a function to show the max value. During a session this function displays the highest measurement value acquired so far in addition to the current measurement value.Another feature which consists of automatic evaluation of the measurement value with regards to the ISO standard 10816-3. When this feature is enabled the measurement value is compared against the three vibration thresholds described in the ISO standard and the current vibration severity zone is displayed through color coding of the value on the screen.1.

The measuring tip should be placed as vertical as possible on the measurement surface in order to receive accurate measurements.English 3.3.4 Vibration calibrator PCE-VC20 / PCE-VC21The vibration meter PCE-VT 3700 can be calibrated with the vibration calibrators PCE-VC20 or PCE-VC21.3.3.5 Instrument case PCE-VT 3700 CASEThe instrument case PCE-VT 3700 CASE is used for safe storage and transport of the vibration meter and its accessories.4 Getting started4.1 Power supplyThree AA-batteries are used to power the vibration meter. The battery compartment is on theback of the device. The device should be turned off before the batteries are replaced. In order to replace the batteries, the two screws which hold the cover in place need to be removed. Afterwards the cover can be removed so the batteries can be inserted in the compartment. The compartment can then be closed by installing the cover and fastening the two screws.The current battery level is displayed in the top right corner of the screen. If the battery charge is insufficient for proper operation of the device the device automatically powers off and the screenbelow is shown on the display.hsilgnEFig. 3 Automatic power off4.2 PreparationConnect the sensor with the spiral cable to the vibration meter before turning it on. The knurlednuts should be tightened to ensure proper connection. In order to turn on the device, the ON/OFFbutton needs to be pressed until the screen backlight turns on and the start-up screen is shown.The start-up screen is shown for about 2 seconds and the device automatically switches to the measurement screen afterwards. The device is turned off by pressing the ON/OFF button untilthe screen backlight turns off. The following icon is displayed on the start-up screen if date andtime need to be set:Fig. 4 Set date & timeEnglish 5 MenuThe main menu can be reached from any screen by pressing the MENU button. The arrow keys are used to navigate the menu items which can be activated with the OK button. The BACK button is used to return from sub menus. The main menu consists of the sub menus Measurement, Calibration, Settings and Info which are explained in detail below. 5.1 MeasurementThe sub menu Measurement is used to configure the different options of the vibration measurement: Measuring unit, parameter, ISO evaluation, display max value.5.1.1 Measuring unitThe measuring unit and the respective frequency range can be adjusted with this menu. The options include acceleration a (10 Hz … 10 kHz), acceleration a (1 kHz … 10 kHz), velocity v (10 Hz … 1 kHz) and displacement d (10 Hz … 200 Hz). This sub menu can also be directly accessed from the main screen by pressing the left arrow key .5.1.2 ParameterThis sub menu is used to adjust the metric of the measured vibration which is displayed as the measurement value on the main screen. It is possible to switch between RMS, peak, peak-peak and crest factor. This sub menu can also be directly accessed from the main screen by pressing the right arrow key .Fig. 5 Measuring unitFig. 6 ParameterE n g l i s h5.1.3 ISO evaluationIn order to enable the automatic evaluation of the current measurement value according to the ISO standard 10816-3, the measuring unit vibration acceleration or vibration velocity in conjunction with the parameter RMS need to be selected. This is necessary since the ISO standard only lists valid vibration severity thresholds for these two combinations. After the correct measurement options were set, the appropriate option for the machine to be measured (group 1 or 2, rigid or flexible mounting) can be selected in this sub menu.When this function is enabled, the name of the enabled group is displayed at the bottom of the main screen together with four color coded items which represent the four vibration severity zones. The current measurement value shown on the screen is compared against the thresholds described in the ISO standard and is automatically color coded according to the thresholds. Additionally, the item which represents the current zone flashes periodically so the vibration severity can be quickly determined.If the automatic evaluation is currently enabled and an incompatible measuring unit (acceleration) or parameter (peak, peak-peak, crest factor) is activated, the evaluation function is automatically disabled and a corresponding hint is displayed on the screen.As described previously the automatic evaluation function requires the measuring unit velocity or displacement in conjunction with the parameter RMS. Otherwise the menu to enable this function cannot be opened and the following hint is displayed on the screen.Fig. 7 Hint ISO evaluation disabledFig. 8 Hint for activation of ISO evaluationMachine groups:∙Group 1: Large machines with nominal power > 300 kW;Electrical machines with shaft height > 315 mmThese machines generally have plain bearings and therated/operating speeds range from 120 RPM to 15,000 RPM.∙Group 2: Machines with nominal power between 15 kW and 300 kW;Electrical machines with shaft height between 160 mm and315 mm.5.1.4 Display max valueThis sub menu is used to activate the display of the max value function. When enabled the max value during a measurement session is displayed under the current measurement value. The BACK button can be used to reset the max value.5.2 CalibrationA vibration calibrator capable of generating a reference vibration of 10 mm/s RMS at 159,2 Hz(e.g. PCE-VC20 or PCE-VC21) is required for the calibration of the vibration meter. The calibration can be started with the sub menu Calibration. The first screen shows the hint regardingthe required reference vibration and the sensor of the vibration meter needs to be mounted onthe vibration calibrator.hsilgnEFig. 9 Hint for required reference vibrationAfter the vibration calibrator was turned on, the calibration can be continued with the OK button.This leads to the calibration screen. This screen again shows the characteristics of the required reference vibration at the top, followed by the current measurement value of the device in a greenfont with the unit mm/s. It is not necessary to adjust the device measurement parameters specifically for the calibration as only the RMS value of the vibration velocity is evaluated duringthis procedure.Fig. 10 Calibration screenHINT: Verify that the required reference vibration is generated by the vibration calibrator before the calibration is performed!English If the current measurement value compared against the reference vibration exceeds the desired tolerance, the device can perform a calibration which can be started by pressing the OK button on the calibration screen and confirming the subsequent dialog.The calibration is performed autonomously by the device and should take less than 5 seconds. After the calibration was finished a pop-up is displayed on the screen with the hint that the calibration was successful as confirmation. Afterwards a short delay the device returns to the main measurement screen.5.3 Settings5.3.1 UnitsThe measurement unit can be switched between the metric system and imperial units.5.3.2 Date & timeThis menu is used to change the date and time which is displayed in the status bar at the top of the screen. The date format can also be changed.5.3.3 Display brightnessThe screen backlight intensity can be adjusted from 10% to 100%.5.3.4 LanguageThis menu is used to switch between different menu languages. Available languages include English, German, French, Spanish, Italian, Dutch, Portuguese, Turkish, Polish, Russian, Chinese and Japanese.5.3.5 Auto power offThis option enables the auto power off function. Available time periods include 1 minute, 5 minutes and 15 minutes. After the set time period has elapsed, the device will automatically turn off and any button press will reset the timer. It is also possible to disable the auto power off function. 5.3.6 Device resetThis menu is used to reset the device to factory settings. Device settings are separate from the calibration and each can be reset individually by selecting the corresponding menu item.A reset of the device settings will load default measurement parameters and reset any remaining menu option to the factory default values. A calibration which may have been performed beforehand is retained.Fig. 11 Confirmation dialogE n g l i s hHINT: If a reset of the calibration is performed, the previously performed calibration will be deleted and a default value for the sensor sensitivity will be selected. It is recommended to perform a calibration after the reset.The reset must be confirmed via the subsequent confirmation dialog when one of the reset options is selected. The device will perform a restart after the reset has been performed.5.4ManualThis sub menu leads to a screen with a QR code. This code can be decoded with a suitable scanner like e.g. a mobile phone and it contains a link which directly leads to the manual of the PCE-VT 3700 for easy access. 5.5InfoThis sub menu shows a screen with the device name and firmware version.Fig. 12 Confirmation dialogEnglish 6 Operation6.1 Measurement screenAfter turning on the device, the main measurement screen is displayed. The mechanical vibration is converted by the sensor into an electrical signal which is subsequently evaluated according to the measurement settings. The result is displayed as the measurement value on the screen and is continually updated with the current value.Default measurement settings (first start or after reset of device settings) consists of the RMS value of vibration velocity in mm/s. When measurement settings are adjusted via the menu, the changes are applied when the screen is returned to the measurement screen and the changes are reflected on the display accordingly.6.2 PreparationDepending on the application and machine to be measured, the desired measurement settings need to be set with the menu. These settings include measuring unit, parameter, units and possibly ISO evaluation or max value.6.3 Perform measurementThe sensor needs to be attached the desired position to perform a measurement. It can be mounted either with a stud bolt or the magnet adapter. If the measuring tip is used in conjunction with the sensor instead of either mounting option, the sensor should be placed as vertical as possible on the measurement surface in order to receive an accurate result.The measurement is performed continuously by the device when on the main measurement screen and no further user input is required.If the ISO evaluation function is enabled, the current measurement value is color coded with regards to the selected thresholds.

产品简介
震动感觉阈值检查仪(SensiometerA)性能介绍本产品通过数字电路控制手柄震动探头
的振幅大小,可以检查受试者震动感觉阈值(VPT,VibrationPerceptionThreshold),为临
床判断感觉神经功能提供客观的数值,并为周围神经疾病的临床诊断提供帮助。

通过提供
连续的阈值数值,可以针对患者就某种治疗进行长期的跟踪和观察,评价治疗效果。

震动
感觉阈值在已知外周感觉受体正常的情况下。

神经中毒性疾病、神经炎症、全身代谢性疾病,等等。

多神经病变的临床改变常常是先
从感觉神经开始,然后是影响到运动神经。

然而临床上,患者很少因为感觉的异常而去医
院就诊,多是病变累及运动神经后才去就诊。

这是因为神经病变引起的早期感觉异常,往
往不易被患者所察觉。

这样会延误神经疾病的早期诊断和治疗。

因此,当临床怀疑某个病
人有神经病变时,就应及时进行各种感觉刺激的检查,震动感觉的检查就是其中之一。

震动感觉检查是感觉神经检查方法中最常使用的方法。

以往常用 128Hz 音叉震动方法检查受试者的震动感觉,虽然它可以作为一种简便的震动感觉检查方法,但是却无法提供震
动阈值(VPT, VibrationPerceptionThreshold)检查所需的强弱数值。

而且其准确性一直被许
多医务人员所置疑。

正因为如此,传统音叉震动感觉检查只能定位为一种粗略的定性方法,
正逐渐被震动感觉阈值(VPT)检查所代替。
