Abstract
The invention relates to a two-position infrared infusion warning device which comprises an upper infrared emitting diode (1), an upper infrared receiving diode (2), a lower infrared emitting diode (1'), a lower infrared receiving diode (2'), a two-circuit signal amplifying unit (3), an MCU (4), a sound and light warning unit (5), a battery power supply unit (6), a Murphy tube (7) and a hose (8). Variation signals are generated through changes of upper infrared signals and lower infrared signals, the variation signals are amplified through the two-circuit signal amplifying unit (3), the MCU (4) receives the variation signals and enables the sound and light warning unit (5) to work, and warning signals are generated. The two-position infrared infusion warning device can be used for monitoring whether infusion is over or whether bubbles exist.
Description
Technical field
The present invention relates to a kind of dibit infrared ray infusion alarm based on infrared principles, belong to medical new technical 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, in treatment, there is very important effect.Patient is accepting transfusion, in the time that liquid is totally lost, if no one's nurse in time processing, air meeting intravasation or blood backflow, thus cause danger, even threat to life.In infusion alarm of the prior art, clinical being difficult to popularized, and all has some problems, as design unreasonable, complicated operation, cost is higher, has brought trouble to clinical use; Sometimes because of the difference of the reasons such as tube for transfusion material, color or liquid color work undesired; Some employing contact type measurements, have caused pollution to medicinal liquid.In addition, there is the possibility of bubble in Murphy pipe below sometimes, once input human body is dangerous equally.
Summary of the invention
The present invention relates to a kind of dibit infrared ray infusion alarm, to realize, transfusion is finished to realize monitoring and monitors whether there is bubble function.
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 '), two-way signal amplification 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 simultaneously and receive signal, when the liquid of flowing through in flexible pipe (8) therein a test point there is difference, by the variation of top and bottom infrared signal, produce variability signals, through two-way signal amplification unit (3) magnification variation signal, MCU Main Processing Unit (4) receives and makes the bright alarm unit of sound (5) work, 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 transmitting and receiving system belong to identical transmitting and receiving system, can acted as reference mutual, upper and lower can be 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 two of bottom infrared receiver diodes (2 ') and receiving system belongs to identical transmitting and receiving system, whether top can be detected transfusion and finish, and whether below can monitor and have bubble to pass through.
When use, only need to be by dibit infrared ray infusion alarm top infrared light emitting diode (1), top infrared receiver diode (2), clamp respectively on the flexible pipe (8) of transfusion with bottom infrared light emitting diode (1 '), bottom infrared receiver diode (2 '), opening power, can start whole-process automatic monitoring, infusion-completed, signal difference, produces alarm signal.
Beneficial effect of the present invention: 1, simple in structure, reliable operation; 2, adopt upper and lower two infrared detection units, wherein a road is that benchmark compares as reference, has avoided working because of the difference of tube for transfusion material, color, liquid undesired, has greatly promoted detection sensitivity and reliability; 3, adopting comparatively advanced MCU is main control chip, in conjunction with optimized algorithm, makes whole circuit working reliable and stable, and rate of false alarm is little.
