附图3是本实用新型的结构示意图。 3 is a structural diagram of the present invention novel.

本调控器有一箱体,其前端有一面板,顶端有一挂环(1),后端有放电池组装盒(22)的槽,用电池锁钮(21)将盒锁定;侧部有个通过小轴与箱体联接的侧盖(17),可绕轴开启180°,墨菲氏管(15)放在侧盖(17)内,管的两侧安有光电传感器(16),侧盖由锁扣(19)和(20)锁定;箱体内安装有电路系统和机械驱动部分。 This regulation has a housing, a front end having a panel, the top has a hanging ring (1), the rear end groove discharge cell box (22), the battery lock knob (21) the cartridge lock; side portion has a through small side shaft and coupled to the housing cap (17), about an axis turned 180 °, Murphy's canal (15) on the side cover (17), on both sides of the sensor tube Anyou Guang power (16), a side cover the latch (19) and (20) is locked; cabinets mounted circuitry and mechanical drive portion.

面板上安有电源开关(4)、指示灯(2)、绿色发光二极管(3)、显示屏(5)、减键(7)、加键(8)、运行键(6)、设定每分钟滴数的按键(9)、报警显示屏(13)。 An power switch (4) on the panel, the indicator (2), a green light emitting diode (3), the display (5), down key (7), plus key (8), running key (6), each set minute drops of keys (9), an alarm display (13).

电路系统包括光电传感器电路,滤波整形电路,按键输入电路,显示屏、指示灯、报警电路,单片微处理机电路。 Circuitry includes a photosensor circuit, a shaping filter circuit, a key input circuit, display, indicator light, alarm circuit, chip microprocessor circuit. 电路部分简述如下: Circuit portions summarized as follows:

首先将输液中的各种要求通过KDEC,KFUN,KADD,向CPU预置设定参数,由光电传感器从墨菲氏滴管两侧获取点滴信号进入U6。 First, the various infusions required by KDEC, KFUN, KADD, the CPU pre-set parameters, obtaining signal enters drip U6 from Murphy's dropper sides by the photosensor. (同时送往绿色发光二极管以高、低电平使其发光)。 (Also sent to the green LED with a high, low to emit light). 经过滤波整形输出至U5,在U5反相后进入CPU的外部计数脉冲输入端。 After shaping filter to the output of U5, U5 inverted to the CPU in the external count pulse input. 这样,每滴下一滴液体CPU得到一个计数脉冲,该脉冲信号与预置设定参数通过CPU的程序处理,从4、8、10、11脚输出控制脉冲,由U4驱动步进电机。 Thus, every drop of liquid dripping CPU obtains a count pulse, the pulse signal with a preset parameter setting processing procedure by the CPU, an output control pulse from 4,8,10,11 pin, drives the stepping motor by the U4. 同时CPU的5、6、7脚连接显示屏的驱动电路U3,再通过CPU的7脚以串行方式输出,在显示屏X1上显示。 5,6,7 CPU while the foot is connected to the display driving circuit U3, pin 7 through the CPU to serially output on a display screen X1.

本电路使用5V可充电源,当电压下降到4.3V以下,通过T1电路使红色指示二极管点亮。 This circuit uses a rechargeable source of 5V, 4.3V when the voltage drops below T1 circuit by the red indicator LED lights.

机械驱动部分包括步进电机(12),电机轴上的丝杠部分安有螺帽(11),它是嵌在用ABS塑料制成的闸阀(14)内,闸阀前端为输液皮管(18)。 Mechanical drive portion comprises a stepper motor (12), the threaded portion of the motor shaft with a safety nut (11), which is embedded in the valve (14) of ABS plastic material, the distal end of the infusion hose valve (18 ).

使用本仪器时,将挂环(1)悬挂在输液瓶下方,与墨菲氏管(15)平行,按电源开关(4),接通电源。 When the instrument is used, the hanging ring (1) is suspended below the infusion bottle, and Murphy's canal (15) in parallel, according to the power switch (4), the power is turned on. 将墨菲氏管放入侧盖内(17),该侧盖可180°活动,由侧盖锁扣锁定(19)(20)。 Murphy's canal into the side cover (17), the side cover can be 180 ° activities, the side cover locking catch (19) (20). 当每滴下一滴液体时绿色发光二极管(3)闪烁一下,通过按键(9)设定每分钟滴数,输液瓶容量大小(以毫升为单位),及输液总量。 When a drop of liquid dropping each green light emitting diode (3) flicker, and set the number of drops per minute through the button (9), the size of the infusion bottle capacity (in ml), and the total amount of the infusion. 或者设定输液瓶容量大小,输液总量,要求输液时间。 Or to set the size of the capacity of the infusion bottle, infusion volume, infusion time requirements. (其数值大小通过按减键(7)加键(8)进行改变,最后按(6)进入运行。单片机根据光电传感器(16)的信号,计算出每分钟点滴数与设定的数据比较(每分钟点滴与毫升的转换常数是按墨菲氏滴管每15滴为一毫升进行换算的)。比较后根据其正、负误差,由单片微处理机发出脉冲信号使步进电机正、反转动,带动电机轴上的螺帽在丝杆上沿螺纹槽沟前后滑动,使闸阀也同时前进、后退,其前端的输液皮管受到压紧或放松,使其精确地按照所设定的参数进行输液。在此期间,显示屏(5)可选择显示当前每分钟点滴数,输液总量及输液时间。当所设定的一瓶液体滴完,发出报警声(13)显示屏闪烁,提醒换瓶。当所设定的输液总量滴完,发出报警声(13)显示屏闪烁,提醒换瓶。当所设定的输液总量滴完,除报警,显示屏闪烁外,步进电机运转夹紧输液管,输液停止。这样 (Its value by pressing the Save key sizes (7) keyed (8) changes, and press (6) into operation. The signal photosensor microcontroller (16), each minute of data is calculated bit by bit comparison with a set number ( per minute and the conversion constant bit mL dropper is carried out according to Murphy's equivalent is a 15 drops per ml). after the comparison in accordance with its positive and negative errors, the pulse signal emitted by the chip microprocessor positive stepping motor, anti-rotation shaft of the motor drive nut slides along the screw thread in the longitudinal groove, the gate valve also forward, backward, transdermal infusion tube by pressing the front end thereof or to relax, so as to precisely set according to the infusion parameter. during this time, the display (5) displays the current number of selectable bit per minute, the total time of infusion and transfusion. when the set liquid bottle dropwise, alarm sound (13) display flashes, decanting alert when the total amount of the infusion set dropwise, alarm sound (13) display flashes to alert decanted. when the total amount of the infusion set dropwise addition alarm, flashing display, the operation of the stepping motor clamping the infusion tube, the infusion is stopped. Thus 止空气进入静脉。如果输液故障致液体滴不下,也将声光报警,提醒护理人员处理故障。输液完成之后,显示屏仍可显示输液最后各种数据。如每分钟滴数,最后输液总量,输液全程所耗时间,为医护人员交接班及病案记录提供方便。 Stop air into the vein. If the infusion liquid drops less than the fault actuation, will sound alarm to alert the caregiver Troubleshooting. After completion of the infusion, the display is still displays the last infusion of various data such as the number of drops per minute of the last infusion volume , the entire infusion time spent for the convenience of medical records and medical records shift.

本机使用四节5号可充电池组装成盒(22),当电池电压下降到4.3V以下时,指示灯(2)发亮提醒更换电池,此时,可拨动电池锁钮(21)取下电池盒进行充电。 This machine uses four AA rechargeable battery assembled into the cartridge (22), when the battery voltage drops to 4.3V or less, the indicator (2) lights up reminder to replace the battery, In this case, the battery lock knob dial (21) removing the battery is charged.

综上所述,由于本实用新型结构简单,单片微处理机性能稳定,且控制精度高,具在实时控制功能,可实现无人看护输液。 In summary, the present invention is simple in structure, stable chip microprocessor performance, and high control accuracy, with the real-time control functions, may be implemented unattended infusion. 从根本上解决了精确控制输液速度的需要。 It solves the precise control of the infusion rate needs fundamental.
