Description
Technical field
This utility model belongs to, and relates to a kind of Ultrasonic Wave Air Detector repacking infusion-completed automatic alarm system.
Background technology
Infusion treatment is the most general Therapeutic Method of hospital, and it to have not available for many oral drugs a little.Hospitals at Present adopts nurse or family numbers of patients to carry out manual supervisory mode to transfusion condition, or employing type of alarm, alarm button is arranged near transfusion position, after patient fluid infusion, patient oneself or retinue is needed to push for emergency button, now nurse's night shift room bell ring, and room corresponding to display transfusion position or position code, nurse tracks according to this information and processes, and this kind of warning system exists following drawback:
1. first, patient may occur neglecting because of falling asleep when infusing, chatting, reading etc. causing liquid medicine in transfusion bottle/bag to be totally lost and the situation of the button that do not push for emergency in time, patient easily occurs that blood back phenomenon even causes blood coagulation to need again to inject, and increases the misery of patient;
2. secondly, liquid medicine also can be caused to be totally lost delay the situation of warning because not seeing transfusion progress for the patient had defective vision, particularly old people;
3. be exactly finally current national ubiquitous common problem, the lazy weight of nurse, making an inspection tour because of manpower is also not cause transfusion to be totally lost the ignorant major reason of nurse.
Utility model content
The purpose of this utility model is to solve the problem, a kind of Ultrasonic Wave Air Detector is provided to reequip infusion-completed automatic alarm system, for clinical transfusion patient, after liquid input, Ultrasonic Wave Air Detector connects with infusion pipeline, detect the air of working fluid in pipeline, bubble, micro-group bubble, foam, the calling system meeting automatic call patient bed label in ward, nurse just can hear the ring tone of patient in time.
To achieve these goals, the technical scheme that this utility model adopts is:
A kind of Ultrasonic Wave Air Detector repacking infusion-completed automatic alarm system, the calling set comprising ultrasonic transducer, signal amplifier, audion, relay and be arranged in night shift room; Ultrasonic transducer is installed on on tube for transfusion, and the signal output part of ultrasonic transducer is connected with the base stage of audion by signal amplifier, and the colelctor electrode of audion is connected on positive source by relay coil, and the emitter stage of audion is connected to power cathode; Connect with the switch of calling set in the contact of relay.
The colelctor electrode of described audion is also connected with protective resistance.
Described ultrasonic transducer is installed on the tube for transfusion at mouth of infusion bottle or transfusion bag mouth place.
Described ultrasonic transducer is installed on the tube for transfusion of distance mouth of infusion bottle or transfusion bag mouth 3 ~ 6cm.
Described ultrasonic transducer is minimum can detect the single isolated bubbles that volume is 30 μ L, and the corresponding time is 500 μ s.
Described power acquisition 24V DC source.
Compared with prior art, this utility model has following beneficial effect:
This utility model by arranging ultrasonic transducer on the tube for transfusion of patient, when ultrasonic transducer detects that tube for transfusion has a bubble, base stage to audion sends triggering signal, now triode ON, relay coil obtains electric, its closing of contact, make the conducting of calling set switching circuit and then alert trigger, therefore solve when Health care staff's shortage, the patient caused makes patient fluids walk sky because of not in time touring, bubble may be entered, avoid medical tangle, when also can solve patient fluid infusion, family members must accompany the misgivings on side simultaneously, in addition, the patient hand-free relatively light to the general state of an illness, totally unnecessaryly dig-in infusion bottle, alleviate intense strain when seeking medical advice.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail:
See Fig. 1, this utility model comprises ultrasonic transducer M1, signal amplifier M2, audion Q2, relay, is arranged at calling set in night shift room and 24V DC source; Ultrasonic transducer M1 is installed on on tube for transfusion 1, and the signal output part of ultrasonic transducer M1 is connected with the base stage of audion Q2 by signal amplifier M2, the colelctor electrode of audion Q2 is connected on positive source by relay coil J1, the emitter stage of audion Q2 is connected to power cathode, and the colelctor electrode of audion Q2 is also connected with protective resistance R; The contact J1-1 of relay connects with the switch of calling set.。Ultrasonic transducer M1 is installed on the tube for transfusion 1 of distance mouth of infusion bottle or transfusion bag mouth 3 ~ 6cm.
Operation principle of the present utility model:
According to the different propagation characteristics of ultrasound wave in different medium, by special circuit analysis process, go out the medium situation in monitored flow duct with intelligent discrimination.As ultrasonic transducer M
1when detecting that tube for transfusion has a bubble, Q
2triode ON, J
1relay coil obtains electric, J
1-1by call maker maintaining station, the closing of contact, can know that this patient fluids is empty.
This utility model precision is high, and capacity of resisting disturbance is strong, and the single minute bubbles of minimum detectable 30 μ L, response time 500 μ s, detection threshold and response time also can measure as requested.Adopt snap-in tubulature simultaneously, mustn't pipeline be blocked, pollution-free to tracer liquid.The not impact of liquid body color and tubing change, accurately by simple for the bubble user of service nurse operation measured in liquid, can collect conveniently.
Above content is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, within the protection domain all falling into this utility model claims.
