摘要:隨著社會的發(fā)展、隨著科技的進步，越來越多的地方需要用到一些高科技設(shè)備來為人們服務(wù)。

　　　目前醫(yī)院普遍使用的是人工監(jiān)控點滴輸液裝置器將液體容器掛在一定高度利用勢差將液體輸入病人體內(nèi)，用軟管夾對軟管夾緊和放松控制滴速藥物的有無將威脅病人的生命安全，為此醫(yī)護人員要不定時的觀察藥物的情況。本設(shè)計根據(jù)需要設(shè)定液位控制高度同時具備報警、高度顯示等功能，使用了紅外對射傳感器使其具有與液面不接觸的特點，可用于有毒、腐蝕性液體液位的控制，簡單、方便、安全、具有較高的使用價值。如何使這種手工操作走向自動化或半自動化讓護理人員監(jiān)控病人打點滴的進程時間得到充分利用，這就要求醫(yī)療器械加速自動化與半自動化進程來提高醫(yī)護質(zhì)量。

　　　本文介紹了一種以單片機為核心操作方便、顯示直觀、可集中控制、具有報警功能的智能型液體點滴速度監(jiān)控系統(tǒng)。該系統(tǒng)可讓醫(yī)護人員在控制室監(jiān)控不同受液者的輸液狀況，也可以直接到輸液室直接改變輸液狀態(tài)，了解病人的輸液進程及時通知處理將快完成的輸液。

Abstract:With the development of society,with the progress of science and technology. The more local shipped need some high-tech equipment to serving people.

     Current hospital commonly used are artificially monitoring intravenous drip infusion fixtures,will hang in a certain height liquid container,using a liquid exchange with a patient's body,input of hoses hose clip clamping and relax control dripping speed,drugs have threatened a patient's life safety.therefore paramedics or timing observation drug situation,this design according to need to set high level control, along with alarm,highly display function,the use of the infrared DuiShe sensor,make its have no contact with liquid surface,can be used for the characteristics of poisonous and corrosive liquid level control,simple,convenient and safe,has high use value. How to make the manual operation to automatic or semi-automatic,let the nursing staff monitor patients the process of intravenous drop full use time to get medical devices,which requires the accelerated automation and semi-automatic process,improve health care quality.

     This article describes a convenient operation display intuitive,centralized control,with alarm, intelligent liquid drip rate monitoring system. The system allows health care workers in the control room monitoring the infusion of different persons by the fluid situation to the infusion room can also change the fluid state directly to understand the patient's infusion progress and timely completion of notification process will be faster infusion.
