Description

一种基于机器视觉的医疗输液速度监测与控制装置技术领域本实用新型属于医疗器械领域,具体涉及一种基于机器视觉的医疗输液速度监测与控制装置,该装置可以配合医疗输液器械使用,是一种用于医院输液的辅助医疗设备。 A medical infusion rate monitoring and control device based on machine vision Technical Field The present invention belongs to the field of medical devices, in particular to a medical infusion speed based on monitoring and control of the machine vision device, the device can be used with medical infusion device, it is a kind of aid for the hospital transfusion medical devices. 背景技术静脉输液是临床治疗的一项常用给药治疗技术,是利用输液管内的液体压强比人体静脉血管内液体压强大的原理,将药液通过导管直接输入到人体静脉。 BACKGROUND OF THE INVENTION Intravenous infusion is a commonly used clinical administration of the therapy, using the liquid pressure in the infusion tube than the fluid pressure in human vein powerful principle, the liquid is directly input into the body through a catheter intravenously. 在输液过程中,液体进入病患静脉的速度直接影响到药物对病患的治疗效果,速度过快,可能会导致病患中毒,严重时可至心力衰竭;速度过慢则可能发生药量不够或无谓地延长输液时间,使治疗效果受影响,增加医务人员的工作量,同时给患者带来不便。 During the infusion, the speed of the liquid into the patient's vein directly affect the therapeutic effect of the drug to the patient, too fast may cause poisoning patients, to be severe heart failure; may occur too slowly enough dose or needlessly prolong the infusion time, the treatment effect is affected, increasing the workload of medical staff, and inconvenience to the patient. 目前,医院中常规临床输液普遍采用传统的挂瓶输液的方式。 Currently, the hospital routine clinical infusion widely used in the traditional way linked to the infusion bottle. 挂瓶输液需要医护人员用眼睛观察,同时,需要医护人员凭经验和直觉根据医嘱和病患的情况手工来调整液滴速度。 It requires medical infusion bottle hanging eye observation, while medical need experience and intuition to adjust the drop velocity according to the situation of the patient and the doctor manually. 在传统的手动调节方式下,输液速度不易精确控制,调整误差大,并且在输液过程中速度还可能会出现波动。 In the traditional way of manual adjustment, difficult to precisely control the infusion rate, a large adjustment error, and the speed is also likely to fluctuate during the infusion. 此外,传统的输液方式需要医护人员人工观测药物的剩余量,以便在药物用完时及时结束输液过程。 In addition, the conventional approach requires medical infusion manual observation residual amount of drug, the purpose of ending the drug infusion process runs. 若医务人员疏忽,没有在药物用完时及时停止,极有可能造成病人出现回血现象,而且,在传统的输液方式下,为避免在输液过程中因意外情况造成输液异常(如:针头脱出或堵塞),往往需要病人自己或者陪同人员或者医护人员时刻进行监视,这无疑会给病人增加痛苦,给病人家属以及医护人员增加负担。 If the medical staff negligence, did not stop when the drug runs out, most likely caused by the patient appear back to the blood phenomenon, and, in the traditional infusion way to avoid accidents caused by infusion abnormalities (such as during the infusion: needle extrusion or blockage), patients often need to own or entourage or staff time to monitor, which will undoubtedly increase the suffering of the patient, the patient's family and medical staff to increase the burden. 为克服手工输液方式存在的上述缺陷,市面上出现了一些检测和控制输液速度的装置,但是这些装置都不十全十美,要么技术上还有欠缺,要么是成本偏高。 To overcome the above shortcomings of manual delivery mode, there are some on the market and detecting means for controlling the infusion rate, these devices are not perfect, there is a lack either technically or a high cost. 输液速度的检测和控制从实现的技术手段上需要考虑一些因素,其中包括:(1)输液流速的有效检测。 Detection and control infusion rate from the technical means of a number of factors need to be considered, including: effective detection (1) of the infusion flow rate. 由于输液的速度受药液的浓度,导管材料特性及管壁光滑程度的影响,如何有效地检测流速是一个需考虑的囡素。 Since the rate of infusion liquid is affected by the concentration, the material properties and smoothness of the conduit wall, is how to effectively detect a flow rate to be considered nan factors. (2)输液流量精度的控制。 Precision control (2) infusion fluid flow. 如何达到控制流速的精度要求又能适当地控制设备的成本,也是一个需考虑的因素。 How to control the flow rate precision equipment cost can be appropriately controlled, but also a factor to consider. (3)输液流量装置尺寸的控制。 (3) control of fluid flow device size. 目前普遍采用的装置尺寸略微偏大,有些甚至采用分离装置实现,如何能改变结构,縮小装置尺寸也是一个值得考虑的因素。 Currently widely used device dimensions slightly larger, and some even use the device to achieve the separation, how to change the structure and size of the device is also a factor worth considering narrowing. 目前,关于医用输液速度检测和流量控制的专利也有很多,如公开号为CN2875460 的专利文献采用了红外光收发器件,利用液体内对光具有折射的原理来对液体进行检测,这样的检测方法具有易实现的优点,但红外光收发装置容易受外界辐射源的干扰,且在莫非氏滴管上的安装红外检测设备工艺要求高,并对安装精确度有很高的要求。 Currently, on the medical infusion speed detection and flow control Patent there are many, as Publication No. CN2875460 Patent Document uses infrared transceiver, by means of the liquid light with the principle of refraction to detect liquid, such a detection method the advantage of easy to implement, but the infrared optical transceiver vulnerable to external sources of interference, and, in the infrared detector does high mounting equipment's dropper on process requirements, and have a high degree of mounting accuracy requirements. 一旦滴管处于歪斜状态,传感器就不能准确地检测到下落的液滴。 Once the dropper in a skewed state, the sensor can not accurately detect the falling drops. 此外,还有部分专利文献中采用了称重原理作为限流装置,虽然该方法原理简单,易实现,但由于不同厂家生产的输液瓶和输液袋所采用的材料和工艺的不同,其重量存在着差异,从而对测量精度产生了一定的影响。 In addition, there are some patent literature as employed weighing principle limiting device, while the principle of the method is simple, easy to implement, but because of the materials and processes of different manufacturers infusion bottles and infusion bags used, the weight thereof is present difference, so that the measurement accuracy had some influence. 如果每次设置时需要对重量参数做初始化处理, 则增加了操作的复杂性。 Initialization processing needs to be done if each of the parameters set by weight, increases the complexity of the operation. 另外市场上也存在一些输液泵之类的设备,但因价格昂贵,大多仅限于在高端重症监护室(ICU)或手术室(OR)使用。 In addition, there are some devices like infusion pumps on the market, but expensive, mostly limited to or operating room (OR) for use in high-end intensive care unit (ICU). 发明内容本实用新型的目的在于提供一种基于机器视觉的医疗输液速度监测与控制装置,该装置能较准确地检测和控制输液的速度,并能对无药液状态等输液过程中可能出现的异常情况做出报警提示,有助于病人对药物的吸收和减少医护人员的护理工作量。 SUMMARY OF THE
