输液瓶液面位置测量及输液报警器的制作研究
摘 要
/便捷式输液报警控制器是用于临床患者输液过程中的一种监测控制装置。当病人在医院输液时，通常需要护士或家人看护。当液体输完时，如果没人看护，会给病人带来很大的麻烦甚至危险【1】。这种输液报警器，可以在输液滴完时，报警器自动发出声信号，提示看护人很快拔掉输液管，在安全时间内更换输液瓶或者停止输液并进行下一步工作，减少了病人和陪床者的负担。
此仪器适用于各种颜色的药液，而且结构简单，体积小，重量轻，体现简约理念。此仪器器材所需的材料价格低廉，利用率高，可反复使用。便捷式输液报警控制器反应灵敏，安全可靠，没有电磁辐射干扰，对病人身体没有伤害；更重要的是它的检测控制装置，不接触药液，安全卫生，让人能更放心。该产品不影响患者走动，便于随处移动。这种输液报警装置让每瓶药液充分输尽，不浪费药液，体现节约理念。总之，这种便携式输液报警器以安全操作、卫生操作为前提，通过灵敏检测电路的智能控制，以节约环保的理念为宗旨，设计之中充分融入了患者至上的人性化理念，整体达到了很好的效果。

THE INFUSION BOTTLE LIQUID LEVEL MEASUREMENT AND STUDY ON THE PRODUCTION OF TRANSFUSION ALARM
ABSTRACT
The new design of electromechanical infusion alarm controller is convenient for patients in the process of a kind of infusion monitoring control device. When patients get injection,they often need a nurse or family nursing.When infusion finished,there will be a lot of trouble or even more dangerous.When infusion finished, alarm automatically give out sound and light signals,reminding nursing staff to pull out the tubing in time，reducing the burden of patients and nursing staff.
This instrument is suitable for various kinds of color, and the solution of simple structure, small volume, light weight, reflects contracted concept. This apparatus of required materials low prices, high efficiency, can use repeatedly. New convenient electromechanical infusion alarm controller senstive reaction, safe and reliable, no electromagnetic radiation, the body without interference to the patient harm; More important is its mechanical test and control device, not contact solution, safety and health, let a person can rest assured. This product does not affect patients ambulate, facilitate everywhere is mobile. This new infusion alarm device let every bottle of liquor fully lost all liquids and not waste, reflect save concept .In a word ,in premise of safe operation and sanitary operation, with the intelligent control of sensitive detective circuit ,with the purpose of energy conservation and environmental protection ,the new design of electromechanical infusion alarm controller is pretty good on the whole.
