The utility model has the advantages that the working strength of nurses can be reduced, and the safety and reliability of infusion can be enhanced.
Description
This utility model belongs to introduces the intravital instrument field of people in the intravenous injection mode with medium, is specifically related to a kind of intelligent peristaltic pump.
Infusion pump is a kind of device of safe, accurate control transfusion.The infusion mode that past people is familiar with is to utilize the potential energy of liquid to do power, be difficult to control steadily in the long term transfusion speed and amount of infusion, be difficult to meet the demands for ask for something precision occasion high and transfusion fast, it is unpredictable particularly to skid off obstruction that blood vessel causes etc. for the bubble that occurs in the transfusion and pipe blocking such as syringe needle, and the malpractice that causes thus is much.Similar products at home and abroad has listing repeatly in recent years, but with this utility model difference is arranged on the performance, and the no bubble warning function that the product of Japanese firm has, the domestic product that has have bubble to report to the police but sensitivity is on the low side.And pipe blocking warning wrong report is more.The transfusion precision generally ± 5-10% scope internal ratio this utility model precision is low.Domestic and international infusion pump does not all have heart rate and detects automatically, so amount of infusion can not be regulated automatically with the heart rate situation.The product noise that has is big, disturbs greatly, and power consumption is many, and warning system is dangerous, uses inconvenient operation.
The purpose of this utility model is to provide a kind of safe and reliable, functional, perfect in shape and function, power consumption is low, noise is little intelligent infusion pump.
The technical solution of the utility model is as follows: intelligent peristaltic pump is the main frame pump with linear translation vane type peristaltic pump, and the main frame pump links to each other with motor, and motor is controlled by drive circuit, and drive circuit is by the computer realization On-line Control.Bubble detection circuit is used for detecting liquid-transport pipe-line and has or not bubble, adopts the multichannel infrared sensing structure, and promptly the multiple tracks infrared detection links to each other with computer through bubble detection and amplifying circuit.Infraluminescence and receiving device place the tube for transfusion both sides, when bubble appears in tube for transfusion, luminous flux changes, and receptor is converted to change in electric with this variation and opens through amplifying circuit and send A/D changer A/D figure signal to deliver to computer, realizes that online bubble reports to the police.The occlusion detection circuit uses high accuracy, many sensitivity pipeline obstruction warning system.Obstruction sensor links to each other with computer through occlusion detection and amplifying circuit, obstruction sensor working pressure pick off, pick off are high-precision, and it is with the big processing of circuit that veers away of the pressure signal on the tube for transfusion, enter microcomputer through the A/D conversion and judge whether to block, realize reporting to the police.The occlusion detection circuit adopts many sensitivity, and its sensitivity can be regulated as required.Heart rate detector links to each other with computer by heart rate detection and amplifying circuit, will be shaped to pulse signal by placing the electrocardiosignal that the electrocardio mornitoring electrode measures on the human body to amplify, send MICROCOMPUTER PROCESSING through the A/D conversion, according to the heart rate situation, adjust transfusion speed and amount of infusion, and realize reporting to the police.Cpu system wiring board core is 51 serial one chip microcomputers.Three amplifying circuits have been installed, i.e. occlusion detection amplifying circuit, bubble detection amplifying circuit and electrocardio detection amplifying circuit on the wiring board.Display lamp and each warning indicator are installed on the infusion pump control panel.The sheet metal structural that upper box is made for the book steel plate, on handle is arranged and is linked as integral body with lower box, the outer surface plastic-blasting.The sheet metal structural that lower box is made by the book steel plate is placed the main frame pump, transformator, and control panel and electric component, pipe blocking, bubble detect, the heart rate detection device all is electrically connected with each alarm device on the control panel.
This utility model has following advantage: 1, this utility model adopts multichannel structure infrared sensor that bubble in the tube for transfusion is detected, and has guaranteed not omission of bubble, and is safe in utilization.2, adopt high accuracy, many sensitivity pipeline obstruction warning system, pressure limit is accurately appropriate, can not report phenomenon by mistake.3, increased heart rate and detected automatically, can be according to heart rate state adjustment transfusion speed, flow is stopped because of the improper malpractice that causes of infusing.4, adopt microcomputer control, improved safety, reliability and the effectiveness of automation degree of equipment and transfusion, and alleviated nurse's working strength.5, product safety is reliable, and is functional, and noise is little, function is complete, decoration is attractive in appearance.
