One end sets photographic plate, and the monitoring to liquid level position, effective drop are realized in the refraction effect that liquid level position occurs using laser
Low false alarm when being monitored to transfusion state.
Brief description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, of the invention is other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is the dimensional structure diagram of transfusion state supervising device provided in an embodiment of the present invention；
Fig. 2 is the laser optical path schematic diagram that level sensing provided in an embodiment of the present invention is；
Fig. 3 is the circuit structure diagram of transfusion state supervising device provided in an embodiment of the present invention.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Fig. 1 shows the overall structure of Transfusion State Monitoring Device.Referring to Fig. 1, Transfusion State Monitoring Device includes：Dropping liquid
Chamber 11.The upper end of the drip chamber 11 is connected with feed tube 12, and lower end is connected with drain pipe 13.Inside drip chamber 11, upper end
Generating laser 14 is provided with, can be to the internal emission laser beam of drip chamber 11.In the bottom of drip chamber, thoughts are set
Tabula rasa 15, for sensing the laser beam produced by the generating laser 14.
Transfusion State Monitoring Device provided in an embodiment of the present invention mainly make use of light to roll in terms of transfusion state monitoring
The principle penetrated.Fig. 2 shows this phenomenon.Referring to Fig. 2, when by the laser of the outgoing of generating laser 14 from the drip chamber 11
When the air incidence in portion is into the liquid of bottom, laser can be reflected at the position of liquid level 111 in itself.This allows for photographic plate
Sensitivity speck on 15 by originally without liquid when A points, migrate to drip chamber 11 B points when having liquid.Using this photosensitive
The migration of point position on photographic plate 15, Transfusion State Monitoring Device is it may determine that the height of the liquid level position in drip chamber 11
It is low, and then infusion process is further controlled, or directly remind the operating personnel of transfusion.
Drip chamber 11 is a hollow cavity, can hold transfusion liquid inside it.The two ends of drip chamber respectively with feed liquor
Pipe 12 and drain pipe 13 are connected.
Generating laser 14 is arranged on the upper end inwall of drip chamber 11.Its function is to the internal emission of drip chamber 11
Laser beam.Also, the exit direction of the laser beam by the outgoing of generating laser 14 should point to the bottom of drip chamber 11.
In the bottom of drip chamber 11, it is provided with for photosensitive photographic plate 15.The photographic plate 15 should be with others electricity
Circuit component is connected with each other, and therefore, when photographic plate 15 senses the change in location of sensitivity speck thereon, liquid level can be judged accordingly
The rising of generation or the change of decline.According to this change, each circuit element in Transfusion State Monitoring Device can enter
The regulation transfusion speed of one step, or warning reminding etc. is carried out to the operating personnel of transfusion, so as to ensure sick in infusion process
The safety of people.
It should be further stated that, during photographic plate 15 can be CCD photographic plates, CMOS photographic plates, or PSD photographic plates
