Abstract
The utility model provides a venous transfusion dripping speed measuring device, which consists of a key-press input circuit, a microprocessor, a voice cue circuit and a display circuit. The output end of the key-press input circuit is connected with the I/O foot of the microprocessor. The control signal and the processing result of the microprocessor are output to the voice cur circuit and the display circuit through the I/O foot. The utility model can help healthcare workers to reduce the work burden of adjusting the venous transfusion dripping speed and has the advantages of easy and convenient operation, quick measurement, high accurate measuring result, low price and easy popularization.
Description
Technical field
This utility model relates to a kind of electron medical treatment auxiliary device, especially a kind of venous transfusion injection (intravenous drip) speed measuring and calculating device.
Background technology
Transfusion is hospital's a kind of medical procedure commonly used.During transfusion, medical personnel's fibrous root is different suitable with the adjustment of venous transfusion drip velocity size by rotating the tube for transfusion pulley according to medicinal liquid kind and transfusion object.In adjusting venous transfusion drip velocity process, drip velocity uses general wristwatch to be estimated by observing the drop number that drips in the Murphy's burette in a period of time by medical personnel usually, the shortcoming of this kind method is that medical personnel are should observe drop and notice that again wrist-watch is walked the time, so operation inconvenience, and the resultant error of estimation is bigger.
The utility model content
This utility model is exactly to provide a kind of venous transfusion drip velocity measuring and calculating device at the problems referred to above, and it is simple to operation that this device is used to calculate the venous transfusion drip velocity, and measuring and calculating is quick, and the results of measuring precision is higher.
The technical scheme that this utility model provides is: a kind of venous transfusion drip velocity measuring and calculating device, form by button inputting circuits, microprocessor, auditory tone cues electric circuit and display circuit, wherein the outfan of button inputting circuits links to each other with the I/O foot of microprocessor, and microprocessor control signal and result export auditory tone cues electric circuit and display circuit to by its I/O foot.
Above-mentioned button inputting circuits is connected with pull-up resistor by button and is constituted; Display circuit adopts the HD44780 Liquid Crystal Module.
This utility model be used to calculate the venous transfusion drip velocity have simple to operation, measuring and calculating fast, the results of measuring precision is high and cheaply advantage such as be suitable for popularizing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail:
Among Fig. 1, this utility model is by button inputting circuits 1, microprocessor 2, and auditory tone cues electric circuit 3 and display circuit 4 are formed.
Among Fig. 2, button inputting circuits 1 is connected with a pull-up resistor R by button SW and is constituted, and each closure of button is to negative saltus step pulse signal of microprocessor input.Microprocessor adopts the 89C51 single-chip microcomputer, and the P1I/O mouth of microprocessor links to each other with the input of auditory tone cues electric circuit 3.Auditory tone cues electric circuit 3 is connected with buzzer SP by driving transistors Q1 and is constituted.Display circuit 4 adopts the HD44780 Liquid Crystal Module, and the control end of this Liquid Crystal Module links to each other with the P1I/O mouth of microprocessor, and the data terminal of Liquid Crystal Module links to each other with the P2I/O mouth of microprocessor.
When this utility model used, medical personnel observed whenever that drippage one dropping liquid drips in the Murphy's burette, just press button of the present utility model to pulse signal of microprocessor input.Microprocessor is added up the adjacent twice pulse interval time by starting inner Timer, thereby calculates venous transfusion drip velocity this moment fast, and the results of measuring microprocessor exports display circuit to and shows.An effective impulse input is whenever received in little processing, just drives auditory tone cues electric circuit and rings.The utlity model has simple to operation, measuring and calculating fast, the results of measuring precision is high and cheaply advantage such as be suitable for popularizing; Can alleviate the work load that medical personnel debug the venous transfusion injection speed effectively.
Claims (2)
1. a venous transfusion injection speed is calculated device, it is characterized in that: by button inputting circuits, microprocessor and display circuit are formed; The outfan of button inputting circuits links to each other with microprocessor I/O mouth; The control end of display circuit links to each other with the I/O mouth of microprocessor with data terminal.
2. venous transfusion injection speed measuring and calculating device according to claim 1, it is characterized in that: button inputting circuits is connected with pull-up resistor by button and is constituted; Display circuit adopts the HD44780 Liquid Crystal Module.
