Description

Dibit infrared ray infusion alarm
Technical field
The present invention relates to a kind of dibit infrared ray infusion alarm based on infrared principles, belong to new medical technology field.Particularly can adapt to medical and family in two ways.
Background technology
At present, be one of requisite route of administration in clinical treatment through venous transfusion, have very important effect in the treatment.Patient is accepting transfusion, when liquid is totally lost, if no one's nurse also process in time, and air meeting intravasation or blood backflow, thus cause danger, even threat to life.In infusion alarm of the prior art, clinical being difficult to is popularized, and all there is some problems, as design unreasonable, complicated operation, cost are higher, bring trouble to Clinical practice; Sometimes work abnormal because of the difference of the reasons such as tube for transfusion material, color or liquid color; Some employing contact type measurements, cause pollution to medicinal liquid.In addition, sometimes there is the possibility of bubble below Murphy pipe.
Summary of the invention
The present invention relates to a kind of dibit infrared ray infusion alarm, to realize terminating realize monitoring and monitor whether there is bubble function to transfusion.
For realizing above-mentioned object, the present invention adopts following technical scheme: a kind of dibit infrared ray infusion alarm, comprises: top infrared light emitting diode (1), top infrared receiver diode (2), bottom infrared light emitting diode (1 '), bottom infrared receiver diode (2 '), simple two-way signal amplifying unit (3), MCU Main Processing Unit (4), the bright alarm unit of sound (5), battery power supply unit (6), Murphy pipe (7), flexible pipe (8); Top infrared light emitting diode (1) and top infrared receiver diode (2) and bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 '), send and Received signal strength simultaneously, when the liquid flowed through in flexible pipe (8) wherein a test point there is difference, by the change of top and bottom infrared signal, produce variability signals, through simple two-way signal amplifying unit (3) magnification variation signal, MCU Main Processing Unit (4) receives and the bright alarm unit of sound (5) is worked, and produces alarm signal.Top infrared light emitting diode (1) and top infrared receiver diode (2) and bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 '), these two transmittings and receiving system belong to identical transmitting and receiving system, can acted as reference mutual, upper and lower can put upside down use.Top infrared light emitting diode (1) and top infrared receiver diode (2) are launched with bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 ') two and receiving system belongs to identical transmitting and receiving system, whether top can be detected transfusion and terminate, and whether below can monitor and have bubble to pass through.
During use, only need dibit infrared ray infusion alarm top infrared light emitting diode (1), top infrared receiver diode (2), clamp on the flexible pipe (8) of transfusion respectively with bottom infrared light emitting diode (1 '), bottom infrared receiver diode (2 '), opening power, whole-process automatic monitoring can be started, infusion-completed, signal difference, produces alarm signal.
Beneficial effect of the present invention: 1, structure is simple, reliable operation; 2, adopt upper and lower two infrared detection units, wherein a road is that benchmark compares as reference, avoids and works abnormal because of the difference of tube for transfusion material, color, liquid, greatly improve detection sensitivity and reliability; 3, adopt comparatively advanced MCU to be main control chip, in conjunction with optimized algorithm, make whole circuit working reliable and stable, rate of false alarm is little.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural frames road figure of the present invention;
Accompanying drawing 2 is circuit diagrams of top of the present invention infrared light emitting diode, top infrared receiver diode;
Accompanying drawing 3 is circuit diagrams of bottom of the present invention infrared light emitting diode, bottom infrared receiver diode;
Accompanying drawing 4 is simple two-way signal amplifying units, the circuit diagram of MCU Main Processing Unit and the bright alarm unit of sound;
Detailed description of the invention:
In order to make technical scheme of the present invention clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail, instantiation described herein, only in order to explain the present invention, is not limited to the present invention.
Detailed description of the invention:
Refer to accompanying drawing 1,2, shown in 3,4, a kind of dibit infrared ray infusion alarm, comprises: top infrared light emitting diode (1), top infrared receiver diode (2), bottom infrared light emitting diode (1 '), bottom infrared receiver diode (2 '), simple two-way signal amplifying unit (3), MCU Main Processing Unit (4), the bright alarm unit of sound (5), battery power supply unit (6), Murphy pipe (7), flexible pipe (8), it is characterized in that: top infrared light emitting diode (1) and top infrared receiver diode (2) and bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 '), send and Received signal strength simultaneously, when the liquid flowed through in flexible pipe (8) wherein a test point there is difference, by the change of top and bottom infrared signal, produce variability signals, through simple two-way signal amplifying unit (3) magnification variation signal, MCU Main Processing Unit (4) receives and the bright alarm unit of sound (5) is worked, produce alarm signal.Top infrared light emitting diode (1) and top infrared receiver diode (2) are launched with bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 ') two and receiving system belongs to identical transmitting and receiving system, can acted as reference mutual, upper and lower can put upside down use.Top infrared light emitting diode (1) and top infrared receiver diode (2) are launched with bottom infrared light emitting diode (1 ') and bottom infrared receiver diode (2 ') two and receiving system belongs to identical transmitting and receiving system.
During use, two infrared emittings and receiving system, Murphy pipe (7) top is fixed in side, side is placed in Murphy pipe (7) below in addition, and opening power, can start whole-process automatic monitoring, infusion-completed, signal difference, produces alarm signal.Whether top can be detected transfusion and terminate, and whether below can monitor and have bubble to pass through.
