This utility model is with respect to prior art; Has following beneficial effect: the contactless oozing of blood alarm device of this utility model perfect through to circuit module; Under the extremely trickle situation of oozing of blood, also can in time monitor the oozing of blood situation, thereby improve the medical monitoring quality.This apparatus structure is simple, and the circuit element is all usual visible element on the market, so its low production cost, cost performance is high.Simultaneously, the monitoring effect of this device is extremely desirable, has improved the medical monitoring quality.It has not only alleviated medical personnel's working strength, and also treatment and the life security to the patient provides safety guarantee.
Description of drawings
Fig. 1 is the fundamental diagram of the contactless oozing of blood alarm device of this utility model;
Fig. 2 is the circuit structure diagram of the contactless oozing of blood alarm device of this utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing this utility model is described in further detail, but the embodiment of this utility model is not limited thereto.
As shown in Figure 1; Contactless oozing of blood alarm device; Comprise Photoelectric Detection module, amplification module, sound and light alarm module and switch module, said switch module is electrically connected with Photoelectric Detection module, amplification module, sound and light alarm module respectively, and said Photoelectric Detection module by signal outfan is electrically connected with the signal input part of amplification module; The signal output part of said amplification module is connected with the signal input part of sound and light alarm module, and reports to the police behind the sound and light alarm module reception signal.
As shown in Figure 2, the acousto-optic detection module adopts and shines light cell; Amplification module adopts two-stage to amplify fortune and sends out, and it is chip used to be LM324N, and has adopted 9018 audion and 555 monostable flip chips in the sound and light alarm module.In circuit structure, the solarization light cell links to each other with 2 feet of first LM324N through the resistance of a 10K, and 6 feet of first LM324N link to each other with 2 feet of second LM324N through the resistance of 10K.
The sound and light alarm module comprises that audion, 555 monostables trigger core, working power and alarm and Light-Emitting Diode; Thereby said working power is input to 4 feet and 8 feet of 555 monostable flip chips and for it dc source is provided; The colelctor electrode of said audion is electrically connected with 2 feet and 6 feet of 555 monostable flip chips, and 3 feet of said 555 monostable flip chips are electrically connected with speaker, Light-Emitting Diode respectively.
