Outer embedded photoelectric detects the real-time closing control work process of infusion controller:
During normal infusion, the power turn-on switch is when retaining medicinal liquid in infusion bottle or the bag; Photoelectric detection switch detects in tube for transfusion less than the transfusion liquid level, and photoelectric receiving tube receives light, and its current collection is low level very; Logic gates IC1-door 3-10 foot output high level, because the electric capacity voltage can not become more, this trailing edge triggers the logic gates IC1-door 1-1 foot control end that is linked to be bistable circuit by logic gates IC1-door 1 and logic gates IC1-door 2; Make logic gates IC1-door 2-4 foot output low level and keep low level; Make compound transistor saturated, its colelctor electrode output voltage is similar to supply voltage, and this moment, functional switch K3 did not press (being in off-state); The compound transistor collector voltage only imposes on acoustics circuit, makes music block IC2, buzzer work.
Lift out again after pressing operating switch K2; Operating switch K2-1 breaks off instantaneous closed back; The trailing edge trigger impulse that produces is added in logic gates IC1-door 2-6 foot control end, makes the output of logic gates IC1-door 2-4 foot be high level and kept high level by the low level upset, makes that compound transistor ends, its colelctor electrode output voltage is similar to 0 volt; Music block IC2 outage; Sound equipment stops, and is the standby detected state that is used to monitor use at this moment, also can do controller state sound equipment discrimination test and use.Press functional switch K3, switch closed condition embeds the holding state that the Photoelectric Detection closer is in use outward.When infusion bottle or the bag flow to end after; When photoelectric detection switch detects the transfusion liquid level of decline; Photoelectric receiving tube is blocked by liquid level, and its current collection is high level very, makes that the output of logic gates IC1-door 3-10 foot is low level by the high level upset; This trailing edge triggers the logic gates IC1-door 1-1 foot logic control end of bistable circuit; Make the output of logic gates IC1-door 2-4 foot be low level by the high level upset and keep that compound transistor is saturated, its colelctor electrode output voltage one tunnel adds to music block IC2 acoustics circuit; One the tunnel through the closed contact of functional switch K3 add to the electromagnetism pull-in winding and the instantaneous adhesive holding circuit of electromagnetism pull-in winding T formed by diode D1, diode D2, IC1-door 3 on; Electromagnetism pull-in winding adhesive swing armature, the action of swing armature link gear embeds the Photoelectric Detection closer outward and closes the liquid road.When electromagnetism pull-in winding voltage rises to the trigger voltage that makes the work of instantaneous adhesive holding circuit, cut off the power supply after the instantaneous adhesive of electromagnetism pull-in winding.
The instantaneous adhesive holding circuit of electromagnetism pull-in winding work process: when electromagnetism pull-in winding voltage rises to the trigger voltage that makes the logic gates IC1-door 3-12 foot upset that is connected into not gate; IC1-door 3-10 foot level is a low level by the high level upset, and this trailing edge triggers bistable circuit control end logic gates IC2-door 2-6 foot, makes logic gates IC2-door 2-4 foot output high level also keep; Make compound transistor end; Electromagnetism pull-in winding, the outage of music block IC2 acoustics circuit, this process is instantaneous completion, so sound equipment is instantaneous sound equipment; The electromagnetism pull-in winding is instantaneous energising, has promptly protected the electromagnetism pull-in winding to economize on electricity again.
Advantage of the present invention:
1) current collection gas component element of the present invention and mechanical component are in one, and the transfusion pipeline section on lower end to the drop dropping funnel of infusion bottle (bag) mouth is accomplished liquid levels is detected and closing control, and the environment of succinctly infusing is avoided scratching, the convenient link processing of infusing.
2) master-plan of the present invention is simple for structure; Outer embedded photoelectric detects the infusion controller and is designed to main frame, embeds Photoelectric Detection closer two parts outward, and it has easy to install, simple for structure, economize on electricity, low preparation cost, characteristics such as practical.
