Description

一种实时监测滴壶液体量的输液组件 技术领域
本实用新型涉及医疗设施技术领域，尤其是涉及一种实时监测滴壶液体量的输液组件。
背景技术
临床观察所见，在患者滴吊瓶时，滴壶内滴水药余量是有严格的要求的。病人病情不同，年龄不同，滴药水滴数也不同。在临床常见是无色输液管和滴壶，随着年龄的老龄化，关注输液器中滴壶液体量是护士和家属必备常识，而现有的无色滴壶难于观察，尤其是对于视力较差的老年人，无法看清滴壶内剩余药量的多少，而造成不必要的医疗事故，为了让病患被人、陪护的家属和护士更方便观察，为护士和陪护家属提供更好服务，现需要一种能够便于观察滴壶内药液剩余量的输液装置。
发明内容
本实用新型的目的在于提供一种实时监测滴壶液体量的输液组件，以解决现有技术中现有的无色滴壶难于观察，尤其是对于视力较差的老年人，无法看清滴壶内剩余药量的多少，而造成不必要的医疗事故的技术问题；本实用新型提供的诸多技术方案中的优选技术方案所能产生的诸多技术效果详见下文阐述。
为实现上述目的，本实用新型提供了以下技术方案：
本实用新型提供的一种实时监测滴壶液体量的输液组件，包括输液管、托座和承重杆，所述输液管上设置滴壶，所述托座为杯型 容器结构，所述承重杆的一端连接在输液架上，另一端设有用于承接托座的环形锢，托座和环形锢的中心均设有通孔，所述滴壶放置在托座内部并且滴壶下方的输液管路贯穿所述通孔向下延伸，所述托座用于承接滴壶的底座上设有压力传感器和控制器，托座的外壁上设有模拟指示灯，所述控制器根据压力传感器的检测数据在模拟指示灯上显示滴壶内的实时液体量。
本输液组件的结构可拆卸并且可重复使用，下面结合安装过程阐述其工作原理，首先将承重杆的一端连接在输液架上的合适高度，然后输液瓶吊装在输液架上，并将输液管与输液瓶连接，将托座放置在承重杆的环形锢上，然后将输液管的底端依次穿过托座和环形锢的通孔向下自由垂放，然后调整承重杆的高度，使得滴壶能够以自由落体的状态放置在托座内部，可以以滴壶上方的输液管刚由紧绷转换到松弛状态为准，此时的滴壶相当于无外力夹持地放置在托座内，然后可以进行正常的输液过程，随着输液过程的进行，滴壶内的药液量会经过增多、持平和减少的三个过程，而这三个过程也伴随着滴壶本身重量的变化，托座底部的压力传感器设置在托座内壁，直接与滴壶接触，当滴壶的重量变化时，重量转变为压力施给压力传感器，该压力传感器发生形变，从而使阻抗发生变化，同时使用激励电压发生变化，输出一个变化的模拟信号，该信号经放大电路放大输出到模数转换器，转换成便于处理的数字信号输出到控制器，控制器的CPU运算控制，并根据预设的程序将这种结果输出到模拟指示灯，模拟指示灯便可以实时显示滴壶内的药液余量；值得说明的是控制器包括的期间以及工作过程为：压力传感器→OP放大→A/D转换→CPU→显示驱动→模拟指示灯，其中模拟指示灯可以为各种型号的显示器或者多个指示灯构成的近似条形的灯泡组件，并且在使用前对滴壶的容量进行测定计算，并设定低液位 所对应的药液重量，以方便设计控制程序，而且优选地选择针对不同规格的输液管设计多个程序，以方便使用；本输液组件通过托座来固定滴壶并和测定滴壶内的药液量，并通过托座外壁设置的模拟指示灯来模拟显示药液量，相对常规无色透明的滴壶来说，更加容易观察，尤其是对于视力不好的老人，而且在输液完毕后托座和承重杆不会受到药液的污染，可以重复使用，只需要更换输液管即可，节约资源。
可选地，托座的侧壁上还设有与控制器相连的低液位蜂鸣器。设置的低液位蜂鸣器用于在滴壶内药液量较低时进行蜂鸣提醒，其工作流程为：压力传感器→OP放大→A/D转换→CPU→低液位蜂鸣器，在预先设定的控制程序内设定低液位药液量所对应的压力传感器测量值，当压力传感器的测量值等于或低于设定值后，控制器控制低液位蜂鸣器进行蜂鸣提醒，在模拟指示灯的基础上进一步通过声音的方式进行低药量提醒，降低了输液过程中医疗事故发生的概率。
可选地，托座上设置有与控制器相连的压力归零按键。为了能够更好地测定滴壶内药液量的值，在安装好输液组件后，由于安装不当可能会造成测量的起始数据有一定的误差，因此选择在安装完毕准备输液前，按下压力归零按键，使得起始的测量数据为零，这样就能更准确地测量滴壶内药液量的数据；值得说明的是，压力归零按键相当于电子秤的归零键，本输液组件主要利用其功能来减小每次使用的压力测量误差，其具体的电路结构和控制原理是常规技术人员所能熟知的，在此不做详述。
可选地，控制器为LED控制器。LED控制器主要功能是通过芯片处理控制LED灯电路中的各个位置的开关，可以选用能够控制灯电路渐变的NE10低压系列控制器。
可选地，托座的内径不小于滴壶的外径。滴壶放置在托座内部，但为了不让滴壶平放，优选的方案为托座的内部形状与滴壶形状相贴合，并且稍大于滴壶，这样既可以保持滴壶原本的输液状态，还能够更好地承接滴壶。
可选的，承重杆的端部设有环形卡扣，环形卡扣上设有螺旋锁紧件，承重杆的环形卡扣套设在输液架上并通过螺旋锁紧件调整环形卡扣在输液架上固定的位置。由于滴壶的高度在不同规格的输液架上可能有所差异，因此设置的承重杆与输液架为可拆卸连接，由此可以根据滴壶的高度来调整承重杆的高度，也就是调整托座的高度，来更好地承接滴壶，提高测量精度。
可选的，承重杆为可伸缩杆体。同样的，不同规格的输液架，会使得滴壶和输液架竖杆的距离不同，承重杆采用可伸缩杆体可以更好地适应不同的输液架，也使得滴壶在托座上保持较好的状态，提高测量的精度。
可选的，输液管的滴壶下方出液端设有定位托垫，所述定位托垫与托座底部贴合。为了使滴壶更好地承接在托座上，由于滴壶的底部一般为偏尖状的设计，因此放置在托座上可能不稳定，设置的定位托垫首先与滴壶构成同一结构，定位托垫与托座能够更好地贴合，由此提高滴壶使用过程中的稳定性。
可选地，定位托垫为弹性垫，定位托垫的中心设有夹持孔，所述夹持孔弹性可拆卸夹紧在滴壶底部。定位托垫与滴壶之间可拆卸连接，可以适应多种规格的输液管和滴壶。
可选地，托座上固定连接有防丢绳，防丢绳的另一端与输液架连接。为了避免托座的丢失，通过防丢绳使其保持连接在输液架上，方便使用。
本实用新型提供的一种实时监测滴壶液体量的输液组件，其有 益效果为：
本输液组件通过托座来固定滴壶并和测定滴壶内的药液量，并通过托座外壁设置的模拟指示灯来模拟显示药液量，相对常规无色透明的滴壶来说，更加容易观察，尤其是对于视力不好的老人，而且在输液完毕后托座和承重杆不会受到药液的污染，可以重复使用，只需要更换输液管即可，节约资源。

如图1-2所示，一种实时监测滴壶液体量的输液组件，包括输液管1、托座2和承重杆3，所述输液管1上设置滴壶4，所述托座2为杯型容器结构，所述承重杆3的一端连接在输液架5上，另一端设有用于承接托座2的环形锢6，托座2和环形锢6的中心均设有通孔，所述滴壶4放置在托座2内部并且滴壶4下方的输液管1路贯穿所述通孔向下延伸，所述托座2用于承接滴壶4的底座上设有压力传感器7和控制器8，托座2的外壁上设有模拟指示灯9，所述控制器8根据压力传感器7的检测数据在模拟指示灯9上显示滴壶4内的实时液体量。本输液组件的结构可拆卸并且可重复使用，下面结合安装过程阐述其工作原理，首先将承重杆3的一端连接在输液架5上的合适高度，然后输液瓶吊装在输液架5上，并将输液管1与输液瓶连接，将托座2放置在承重杆3的环形锢6上，然后将输液管1的底端依次穿过托座2和环形锢6的通孔向下自由垂放，然后调整承重杆3的高度，使得滴壶4能够以自由落体的状态放置在托座2内部，可以以滴壶4上方的输液管1刚由紧绷转换到松弛状态为准，此时的滴壶4相当于无外力夹持地放置在托座2内，然后可以进行正常的输液过程，随着输液过程的进行，滴壶4内的药液量会经过增多、持平和减少的三个过程，而这三个过程也伴随着滴壶4本身重量的变化，托座2底部的压力传感器7设置在托座2内壁，直接与滴壶4接触，当滴壶4的重量变化时，重量转变为压力施给压力传感器7，该压力传感器7发生形变，从而使阻抗发生变化，同时使用激励电压发生变化，输出一个变化的模拟信号，该信号经放大电路放大输出到模数转换器，转换成便于处理的数字信号输出到控制器8，控制器8的CPU运算控制，并根据预设的程序 将这种结果输出到模拟指示灯9，模拟指示灯9便可以实时显示滴壶4内的药液余量；值得说明的是控制器8包括的期间以及工作过程为：压力传感器7→OP放大→A/D转换→CPU→显示驱动→模拟指示灯9，其中模拟指示灯9可以为各种型号的显示器或者多个指示灯构成的近似条形的灯泡组件，并且在使用前对滴壶4的容量进行测定计算，并设定低液位所对应的药液重量，以方便设计控制程序，而且优选地选择针对不同规格的输液管1设计多个程序，以方便使用；本输液组件通过托座2来固定滴壶4并和测定滴壶4内的药液量，并通过托座2外壁设置的模拟指示灯9来模拟显示药液量，相对常规无色透明的滴壶4来说，更加容易观察，尤其是对于视力不好的老人，而且在输液完毕后托座2和承重杆3不会受到药液的污染，可以重复使用，只需要更换输液管1即可，节约资源。
实施例2：
在上述实施例的基础上，作为进一步的优选方案：如图1、图2所示，托座2的侧壁上还设有与控制器8相连的低液位蜂鸣器10。设置的低液位蜂鸣器10用于在滴壶4内药液量较低时进行蜂鸣提醒，其工作流程为：压力传感器7→OP放大→A/D转换→CPU→低液位蜂鸣器10，在预先设定的控制程序内设定低液位药液量所对应的压力传感器7测量值，当压力传感器7的测量值等于或低于设定值后，控制器8控制低液位蜂鸣器10进行蜂鸣提醒，在模拟指示灯9的基础上进一步通过声音的方式进行低药量提醒，降低了输液过程中医疗事故发生的概率。
实施例3：
在上述实施例的基础上，作为进一步的优选方案：如图1、图2所示，托座2上设置有与控制器8相连的压力归零按键11。为了能够更好地测定滴壶4内药液量的值，在安装好输液组件后，由于安 装不当可能会造成测量的起始数据有一定的误差，因此选择在安装完毕准备输液前，按下压力归零按键11，使得起始的测量数据为零，这样就能更准确地测量滴壶4内药液量的数据；值得说明的是，压力归零按键11相当于电子秤的归零键，本输液组件主要利用其功能来减小每次使用的压力测量误差，其具体的电路结构和控制原理是常规技术人员所能熟知的，在此不做详述。
实施例4：
在上述实施例的基础上，作为进一步的优选方案：如图1所示，控制器8为LED控制器。LED控制器主要功能是通过芯片处理控制LED灯电路中的各个位置的开关，可以选用能够控制灯电路渐变的NE10低压系列控制器。
实施例5：
在上述实施例的基础上，作为进一步的优选方案：如图1、图2所示，托座2的内径不小于滴壶4的外径。滴壶4放置在托座2内部，但为了不让滴壶4平放，优选的方案为托座2的内部形状与滴壶4形状相贴合，并且稍大于滴壶4，这样既可以保持滴壶4原本的输液状态，还能够更好地承接滴壶4。
实施例6：
在上述实施例的基础上，作为进一步的优选方案：如图1、图2所示，承重杆3的端部设有环形卡扣12，环形卡扣12上设有螺旋锁紧件13，承重杆3的环形卡扣12套设在输液架5上并通过螺旋锁紧件13调整环形卡扣12在输液架5上固定的位置。由于滴壶4的高度在不同规格的输液架5上可能有所差异，因此设置的承重杆3与输液架5为可拆卸连接，由此可以根据滴壶4的高度来调整承重杆3的高度，也就是调整托座2的高度，来更好地承接滴壶4，提高测量精度，承重杆3为可伸缩杆体。同样的，不同规格的输液 架5，会使得滴壶4和输液架5竖杆的距离不同，承重杆3采用可伸缩杆体可以更好地适应不同的输液架5，也使得滴壶4在托座2上保持较好的状态，提高测量的精度。
实施例7：
在上述实施例的基础上，作为进一步的优选方案：输液管1的滴壶4下方出液端设有定位托垫14，所述定位托垫14与托座2底部贴合。为了使滴壶4更好地承接在托座2上，由于滴壶4的底部一般为偏尖状的设计，因此放置在托座2上可能不稳定，设置的定位托垫14首先与滴壶4构成同一结构，定位托垫14与托座2能够更好地贴合，由此提高滴壶4使用过程中的稳定性，定位托垫14为弹性垫，定位托垫14的中心设有夹持孔，所述夹持孔弹性可拆卸夹紧在滴壶4底部。定位托垫14与滴壶4之间可拆卸连接，可以适应多种规格的输液管1和滴壶4。
实施例8：
在上述实施例的基础上，作为进一步的优选方案：如图1所示，托座2上固定连接有防丢绳15，防丢绳15的另一端与输液架5连接。为了避免托座2的丢失，通过防丢绳15使其保持连接在输液架5上，方便使用。
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。因此，本实用新型的保护范围应以所述权利要求的保护范围为准。
