Description
Technical field
This utility model relates to the monitoring infusion technical field, specifically is a kind of liquid dropping speed monitoring system.
Background technology
Abroad early to intelligent infusion set research; Early several years ago, the many berths of being in hospital of developed country just have been equipped with infusion pump, and it is a kind of multi-functional transfusion device; Better performances; But cost an arm and a leg, need about 20,000 yuans, most three grades of hospitals below first-class are this kind equipment not all.Some homemade infusion sets are also arranged in the market, but reason is failed large-area popularizing because kind is few, and performance need improves, and price is more expensive etc.
Use at present the widest dropper to be still and controls dropping speed, and the speed of drop is still through visual observation and judges through the degree of tightness of control infusion tube chuck, so not only inaccurate but also inconvenient.On the other hand, the people that when transfusion liquid is low, must accompany and attend to notifies the nurse, and the withdrawal of needle to patient is removed in the work that the nurse just can put down on hand in a hurry, thereby has caused the confusion of work.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, this utility model provides a kind of liquid dropping speed monitoring system, can finish monitor, can monitor the process of transfusion again transfusion.
This utility model is realized with following technical scheme: a kind of liquid dropping speed monitoring system; This system comprises the microcontroller that Detection & Controling are used; Be connected the button that is used to set infusion information with microcontroller, be connected the display device that is used to show dropping speed, amount of infusion and bed item with microcontroller, the alarm device that is connected with microcontroller; The motor-drive circuit that is connected with microcontroller; Be connected the checkout gear that is used for the monitoring liquid dropping speed with microcontroller, be connected the communication module that is used for external device communication with microcontroller, to the power module of said apparatus power supply.
The beneficial effect of this utility model is: volume is little, practical, safe, and it is few to reduce peripheral cell, and cost is low; But easy to operate single-set operation also can onlinely use, and has alleviated nurse's labor intensity.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Fig. 1 is this utility model theory diagram,
Fig. 2 is this utility model circuit diagram;
Fig. 3 is this utility model systems soft ware flow chart.
The specific embodiment
As shown in Figure 1; The microcontroller that liquid dropping speed monitoring system has Detection & Controling to use; Be connected the button that is used to set infusion information with microcontroller, be connected the display device that is used to show dropping speed, amount of infusion and bed item with microcontroller, the alarm device that is connected with microcontroller; The motor-drive circuit that is connected with microcontroller; Be connected the checkout gear that is used for the monitoring liquid dropping speed with microcontroller, be connected the communication module that is used for external device communication with microcontroller, to the power module of said apparatus power supply.
As shown in Figure 2, microcontroller adopts STC10F04XE enhancement mode 51 single-chip microcomputers.Display device adopts charactron to show, wherein 3 charactrons show dropping speed and amount of infusion, and 1 charactron shows the bed item.System is provided with an item, infusion bottle capacity, liquid dropping speed through button or upper computer software.Microcontroller is realized dripping the control of speed through motor-drive circuit control step driven by motor peristaltic pump.Checkout gear adopts infrared emission to pipe, and infrared emission realizes that to pipe to dripping the accurate detection of speed, software carries out self adaptation according to testing result to control circuit to be regulated.Alarm device adopts sound and light alarm, and when empty liquid occurring, tube for transfusion blocks and infusing end, alarm signal can utilize light emitting diode and buzzer to realize the sound and light alarm of main frame.Communication module adopts the RS232 serial communication, realizes the transfer of data of slave computer to upper main frame through this serial port, and then can realize long-range, the Centralized Monitoring to device.
It is Menu key that four first buttons of button are arranged in the present embodiment, and this Menu key contains three sub-menu and is respectively: bed item, amount of infusion, drop drip speed.Can select the submenu of present required setting through pressing this Menu key.After choosing submenu, can press the 2nd and the 3rd key the numerical value of submenu is set, and the numerical value that sets can show through four charactrons.The 4th key is start key, set three parameters of front after, press the 4th key, instrument begins life's work.It is accurate to the control of dripping speed to drive peristaltic pump with the Single-chip Controlling motor, through button or upper computer software an item, infusion bottle capacity, liquid dropping speed is set.Speed can be dripped according to the drop that configures earlier in system, according to former repeatedly experimental data, obtains and the corresponding stepper motor speed of this speed, then directly through driving circuit drives motor operation (open loop control); Infrared tube detects and drips speed simultaneously, and testing result and setting value are compared, if error is excessive, system can finely tune (closed loop control) to motor again.More than all settings all can be sent on the host computer, the nurse just can observe on the computer of chief duty room.In infusion process, occur abnormal situation as: " drum pin ", liquid flow are not smooth etc.; Reality is dripped fast and a setting very big error of speed meeting appearance at this moment; If error all existed in continuous 10 seconds, device will send warning, the flicker that the display lamp of the 4th key top can be rapid simultaneously; Alarm also can appear on the upper computer software simultaneously, need fix a breakdown with the prompting nurse.
Native system can use separately, also can jointly control with host computer, and slave computer adopts open loop and the bonded control algolithm of closed loop through single-chip microcomputer, and control step driven by motor peristaltic pump carries out fast and accurate control dripping speed; Utilize infrared tube to dripping the accurate measurement of speed, situation such as, transfusion end smooth to " drum pin ", liquid flow are carried out this locality and remote alarms.
As shown in Figure 3, the mastery routine of single-chip microcomputer is mainly accomplished the scanning to button, and the relevant parameter of definite user input; With intervalometer 1 regularly, interrupt timing refreshes charactron, keeps its normal demonstration; Intervalometer 0 regularly according to the parameter that button is provided with, is adjusted regularly length, controls the frequency of output pulse signal, and then the control step rotating speed of motor, finally reaches the purpose of control drop speed; Serial ports interrupts being used for receiving the related command parameter of host computer.
