A kind of intelligent spiral bar infusion setTechnical field
The invention belongs to field of medical device, be specifically related to a kind of intelligent spiral bar infusion set.
Background technology
Along with medical system reform deeply and the development of social senilization, namely inpatient is many, extra bed is many, elderly patients are many, transfusion patient is many in hospital " more than four two is few ", medical personnel are relatively less, household's time few phenomenon of accompanying and attending to is more and more obvious, be in busy in medical personnel be difficult to accomplish that the whole process to transfusion patient is accompanied one to one.And for patient such as application specific drugs and heart disease, old age, child etc., then must strictly control transfusion speed to ensure medication effect and drug safety.
At present, transfusion patient per minute number drips number by nurse's number and manual adjustments transfusion device pulley regulates, often occur due to patient's self-regulated drip the reasons such as speed, the transfusion change of position, inserting needle position be movable cause transfusion too fast, cross slow or punctures blood vessel wall and cause intravenous extravasation, local swelling, obstruction etc. affects medication to treat; Sometimes loosen nurse slightly, also have the situation that medicine in bottle drips only completely, tube for transfusion upper end enters air to occur.In addition, because of medical personnel carelessness or other reasons, have bubble sometimes in tube for transfusion, if check not in time, discharge bubble can to patient health produce harm; Also may there is malaise symptoms in patient, medical personnel need the tour of variable interval in busy work could understand in time transfusion whether safety, smoothly in infusion process, and seek medical advice peak period or extra bed many when be just difficult to reply.
Summary of the invention
The object of the present invention is to provide a kind of intelligent spiral bar infusion set, to whether having in infusion flow rate, tube for transfusion the health of patient in bubble or blocking, infusion process can monitor, if there is abnormal timely warning reminding.
The technical solution adopted for the present invention to solve the technical problems is: a kind of intelligent spiral bar infusion set, comprise tube for transfusion, fixed mount, flow sensor, air bubble sensor, pressure transducer, pressure transducer, temperature sensor, heart rate sensor, described fixed mount is sheathed to be fixed on tube for transfusion, described fixed mount is provided with screw rod, screw rod consistent with tube for transfusion direction and with tube for transfusion close contact, described screw rod is connected with motor, described flow sensor, air bubble sensor, pressure transducer, pressure transducer, temperature sensor, heart rate sensor is connected with single-chip microcomputer, described single-chip microcomputer is also connected with piezoelectric buzzer, described flow sensor, air bubble sensor, pressure transducer is arranged on tube for transfusion.
Particularly, described flow sensor comprises LED emitter and receptor, and described LED emitter and receptor are arranged at the both sides of the murphy's dropper of tube for transfusion respectively.
Particularly, described air bubble sensor comprises ultrasonic transmitter and ultrasound probe, and described ultrasonic transmitter and ultrasound probe are placed in the both sides of tube for transfusion.
Particularly, described pressure transducer is arranged on the small hose of tube for transfusion front end.
The present invention has following beneficial effect: infusion set of the present invention accurately can control infusion flow rate, each sensor signal is by single-chip microcomputer identification rear drive piezoelectric buzzer ring, Real-Time Monitoring is carried out and instant alarming to having bubble or the abnormal conditions such as blocking, patient body discomfort in the pipe occurred in infusion process, automatization, Intellectualized monitoring are realized to infusion process, accurately, safety, alleviate the workload of medical personnel.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As Fig. 1, shown in Fig. 2, a kind of intelligent spiral bar infusion set, comprise tube for transfusion 1, fixed mount 2, flow sensor, air bubble sensor, pressure transducer 11, pressure transducer, temperature sensor, heart rate sensor, fixed mount 2 is sheathed to be fixed on tube for transfusion 1, fixed mount 2 is provided with screw rod 3, screw rod 3 consistent with tube for transfusion 1 direction and with tube for transfusion 1 close contact, screw rod 3 is connected with motor 4, flow sensor, air bubble sensor, pressure transducer 11, pressure transducer, temperature sensor, heart rate sensor is connected with single-chip microcomputer, single-chip microcomputer is also connected with piezoelectric buzzer, flow sensor, air bubble sensor, pressure transducer is arranged on tube for transfusion 1.Flow sensor comprises LED emitter 5 and receptor 6, and LED emitter 5 and receptor 6 are arranged at the both sides of the murphy's dropper 9 of tube for transfusion 1 respectively.Air bubble sensor comprises ultrasonic transmitter 7 and ultrasound probe 8, and ultrasonic transmitter 7 and ultrasound probe 8 are placed in the both sides of tube for transfusion 1.Pressure transducer 11 is arranged on the small hose 10 of tube for transfusion 1 front end.
The continuously extruded tube for transfusion 1 being full of liquid of screw rod more than 3 spiral prominence lift angle, promotes liquid in pipe and flows downward.Screw rod 3 transmission must be faster, and liquid is extruded more, otherwise fewer, can accurately control infusion pump flow.Transfusion speed, not by liquid level and patient body position's variable effect, completes Ultra-Low Speed to transfusion at a high speed.
Flow rate detection: the LED light line that LED emitter 5 sends is through the drop in murphy's dropper 9, and then received device 6 light cell absorbs, and goes into voltage slave pulses, by the umber of pulse of measurement unit time, calculates flow velocity.
Bubble detects: ultrasonic transmitter 7 produces potential pulse to the bubble passed through, and ultrasound probe 8 receives pulse signal, and signal transmission is reported to the police to piezoelectric buzzer by single-chip microcomputer.
Fluid path jam detection: be placed in by pressure transducer 11 on the small hose 10 of tube for transfusion 1 front end, covers with adhesive plaster, and fluid path blocks, loine pressure increases, the voltage of pressure transducer 11 increases, and namely fluid path blocking occurs, and signal transmission is reported to the police to piezoelectric buzzer by single-chip microcomputer.
Pressure transducer is for the blood pressure state of patient during monitoring transfusion, heart rate sensor is for monitoring heart rate blood state during patient fluid infusion, temperature sensor for monitoring body temperature during patient fluid infusion, each sensor signal by after single-chip microcomputer identification, driving pressure electric buzzer ring.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structure change made under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure part are known technology.
