This utility model adopts traditional diode, transistor circuit, and whether conducting is as the circuit operation switch with diode, and circuit structure and its whole structure be brevity and lucidity very, low processing cost, and increase the cost of disposable infusion device hardly.By the level sensing ball float, quickly and accurately the liquid level dropping signal in the infusion liquid drop display bottle is converted to the photoelectric sensing signal, make control device control transfusion stopper and alarm device work; Its transfusion stopper can be automatically and is accurately stopped transfusion, prevents the generation of " blood back " phenomenon effectively.Follow the termination of infusion process, alarm lamp flicker can appear according to user's demand, buzzer is rung or vibration alarming and to the medical duty room long-distance alarm, make medical personnel can in time go to processing, both improved the medical matters quality, eliminate patient or entourage's psychological burden again, also alleviated the labor intensity that medical personnel constantly make an inspection tour back and forth to a certain extent.
Description of drawings
Accompanying drawing 1 is an assembly structure sketch map of the present utility model; Accompanying drawing 2 is complete section schematic rear view of accompanying drawing 1; Accompanying drawing 3 is circuit theory sketch maps of the present utility model.
Specific embodiments
From accompanying drawing 1,2 visible unitary construction of the present utility model and internal part distribution situations, automaton is arranged in the casing 27, on machine shell panel, be provided with vibration alarming and buzzing warning selector switch 5, alarm lamp 6, alarm buzzer 8, on casing, also be provided with long-distance alarm jack 7, also have the alarm relay 28 that each warning piece is controlled in the circuit assembly 25 in casing; On casing, also have for infusion tube 3 lay localized M type support 4 and the L type transfusion that matches with support by plug-in strip 2, and battery main switch 1, power line 17, power on light 10, machine box hanged hook 9; Vibrator 20 adopts external, is connected with jack on the casing by plug 21, and vibrator is provided with failure of oscillation switch 19 and links up with 18.On infusion tube, be provided with drop display bottle 11, in this bottle, be provided with level sensing ball float 12, the sensing ball float matches with liquid level optoelectronic sensor in the automaton, the liquid level optoelectronic sensor comprises sensor activity folder 15, this folder is clipped in the latter half of drop display bottle during use, the Jia Kou both sides just in time along the drop display bottle be provided with light emitting diode 14 and base assembly, light sensitive diode 16 and base assembly thereof radially symmetrically, these two diodes are connected with circuit assembly in the automaton by photoelectric sensing wire harness 13.Power supply 26 is arranged in the casing, for steadily of centre of gravity generally is positioned on Lower Half, be advisable to adopt DC current, circuit assembly can be arranged on the casing middle part or be provided with as the case may be, also be provided with electromagnetic force device 22 with M type support corresponding section, iron core 23 ends of stretching out in the electromagnetic force device and the transfusion of L type are hinged by the afterbody of plug-in strip, at the also cored return spring 24 in electromagnetic force device bottom.
Under applying working condition, energized, the storage of drop display bottle endogenous cause of ill is expired medicinal liquid and the sensing ball float is swum on the medicinal liquid surface is the upper position of drop display bottle; Be clipped in the light beam that the light emitting diode on the sensor activity folder of drop display bottle bottom sends, do not sheltered from and penetrated medicinal liquid by the sensing ball float this moment, received the instant conducting of this light sensitive diode by the light sensitive diode of establishing relatively.At this moment the switch triode BG that is connected with light sensitive diode
1No current passes through, so BG
2Conducting, pliotron BG
3Not conducting, make circuit such as electromagnetic force device, alarm lamp, alarm buzzer/vibrator and long-distance alarm jack all no current pass through, infuse this moment stopper and alarm device are inoperative.When transfusion finishes, position at the bottom of the sensing ball float in the drop display bottle drops to bottle, just in time the light beam that light emitting diode is sent shelters from, and light sensitive diode turns to cut-off state by conducting immediately, has therefore raised switch triode BG
1Base potential, BG
1Conducting, BG
2Turn to by original conducting and to end, and pliotron BG
3Turn to conducting and drive the comprehensive conductings of circuit such as electromagnetic force device, alarm lamp, alarm buzzer/vibrator and long-distance alarm jack by original ending.At this moment, the iron core of electromagnetic force device bounces back under the electromagnetic force effect fast, one side compression retracteding position spring, pulling on one side is stuck in the infusion tube of transfusion between plug-in strip and M type support, when infusion tube is drawn as V-arrangement, medicinal liquid can't be by ending, meanwhile alarm lamp, alarm buzzer/vibrator constantly send flicker light, ring or vibrate and carry out many signal alarms; In case of necessity, also can pass through the long-distance alarm jack, report to the police through wired UNICOM medical duty room with the ward warning system.In addition,, use commercially available common alligator clamp or transform a little and it can be clamped on the general drip stand, also can adopt hook mode to hang on the drip stand because automaton is small and exquisite; Power supply is good with rechargeable battery then.
