Description
Technical field
The present invention relates to a kind of alarm of infusion set.
Background technology
Existing photoelectric infusion device can't solve the problem of low-power consumption, generally adopt the transformator of 220V commentaries on classics 5V, but transformator is had no a sense of safety patient, and the accident of transformator blast is also of common occurrence; Perhaps adopt the aneroid battery method of high power capacity, but the method increases cost, and also relative complex of battery detection circuit, need to adopt integrated circuits such as amplifier.
Summary of the invention
The present invention will solve the existing high problem of photoelectric infusion device power consumption, and a kind of photoelectric infusion alarm of low in energy consumption, automatic warning is provided.
Technical scheme of the present invention:
Photoelectric infusion alarm is characterized in that: comprise infusion test circuit, buzzer, master controller, battery detection circuit, display lamp, described infusion test circuit, buzzer, battery detection circuit, display lamp all are connected on the master controller;
Described infusion test circuit comprises light receiver, light emitters, and described light receiver is given master controller according to the different voltage signal of the strong and weak different transmission of the optical signal that receives from light emitters;
Described battery detection circuit is connected with battery, and battery voltage signal is passed to master controller after dividing potential drop, and is the master controller power supply;
Described master controller judges according to the voltage signal of light receiver transmission whether transfusion is finished, control display lamp and buzzer carry out sound and light alarm under the situation of no liquid medicine, the voltage signal that transmits according to battery detection circuit is judged the electric weight of battery, and control display lamp and buzzer carry out sound and light alarm under the battery low electricity condition.
Further, described master controller is the LPC900 series monolithic.
Further, described light emitters and light receiver are on the same horizontal line.
Technical conceive of the present invention: tube for transfusion is a lucite pipe, and during no liquid medicine, tube wall is very little to the influence of light in the pipe, and light is similar to straight passing through; When in the pipe liquid medicine being arranged, light can produce refraction, and the advance route of light is changed.On a horizontal line, place a light emitters and a light receiver can achieve the goal according to this principle needs of light, light receiver is transformed into the signal of telecommunication to optical signal, and the optical signal power that light receiver receives under water and the anhydrous two states is arranged is different, thereby make signal of telecommunication difference, through oversampling circuit control, just can under the situation of no liquid medicine, report to the police.The principle of battery detecting then is, the voltage signal of battery is directly linked on the AD pin on the master controller through dividing potential drop, and master controller just can be monitored in real time to cell voltage like this, reaches the purpose of battery low-voltage warning.
Beneficial effect of the present invention: liquid medicine is not had any pollution, report to the police promptly and accurately, can use continuously for a long time; Low-power consumption, the joint general dry battery of 6V/200mAh can use a wheat harvesting period (calculating by 8 hours service time of every day); Low battery voltages is reported to the police, and can report to the police automatically before battery uses up, and can effectively avoid the malpractice that causes because of dead battery; Real time monitoring transfusion liquid level not only brings great convenience to nursing, and safe and reliable, can avoid the generation of transfusion accident effectively.
Description of drawings
Fig. 1 is circuit theory diagrams of the present invention.
The specific embodiment
Photoelectric infusion alarm comprises infusion test circuit, buzzer, master controller, battery detection circuit, display lamp, and described infusion test circuit, buzzer, battery detection circuit, display lamp all are connected on the master controller;
Described infusion test circuit comprises light receiver, light emitters, and described light receiver is given master controller according to the different voltage signal of the strong and weak different transmission of the optical signal that receives from light emitters;
Described battery detection circuit is connected with battery, and battery voltage signal is passed to master controller after dividing potential drop, and is the master controller power supply;
Described master controller judges according to the voltage signal of light receiver transmission whether transfusion is finished, control display lamp and buzzer carry out sound and light alarm under the situation of no liquid medicine, the voltage signal that transmits according to battery detection circuit is judged the electric weight of battery, and control display lamp and buzzer carry out sound and light alarm under the battery low electricity condition.
Described master controller is the LPC900 series monolithic.
Described light emitters and light receiver are on the same horizontal line.
Specific implementation process:
With reference to Fig. 1, J1 is a battery interface, and S1 is a switch, and the burning voltage that U2 (perhaps U3) reduces to 3V to cell voltage is powered to U1, and C2, C3, four electric capacity of C4, C5 play the effect of filtering burr, make voltage more stable; L2 is a display lamp, and when No. 3 feet of U1 were put high level, L2 was bright, otherwise just goes out, and it and buzzer F1 carry out sound and light alarm together; Buzzer F1 is by No. 2 foot control systems of U1, when this pin is high level, and audion T2 conducting, buzzer rings, otherwise buzzer does not just ring; By R9, the bleeder circuit of R8 is passed to No. 7 feet of U1 to battery voltage signal, and No. 7 feet are AD pins, can obtain magnitude of voltage by programming, thereby judges the electric weight of battery.R1, R2, R3, L1, B1 are the infusion test circuit, and L1 is a light emitters, and B1 is the light accepter, B1 receives the light from L1, and when in the pipe during no liquid medicine, light is straight to be passed through, when in the pipe liquid medicine being arranged, light can reflect, thus the light intensity decreasing that B1 is received; And B1 receives different light intensity, and the voltage at its two ends can change, and finally causes audion T1 in conducting with by changing between the two; T1 conducting when liquid medicine is arranged, No. 6 feet of U1 show low level; During no liquid medicine T1 by, whether No. 6 feet of U1 show high level, finish thereby single-chip microcomputer U1 can judge transfusion.
The described content of this description embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
