Description
Technical field
This utility model belongs to medical instruments field, has been specifically related to a kind of transfusion dripping controller of controlling transfusion speed based on drop sound wave vibration signal.
Background technology
When at present carrying out infusion treatment in medical institutions such as the large, medium and small type hospital of China and subordinate's community sanitary institute, clinics, transfusion speed and amount of infusion almost all are inaccurate.Transfusion speed is that the nurse controls flow rate of liquid by the manual pulley that rotates on the transfusion device, and amount of infusion also is that the nurse is with only having the liquid bottles of two labellings to topple over rear estimation.The instrument and equipments such as transfusion speed monitoring are not widely adopted, so not only can affect the expection therapeutic effect, and for some medicines to the responsive strictly control transfusion speed of human organ effect and amount of infusion, because individual variation body tolerance is different, particularly in operation, after the major operation and the critical needs of the state of an illness strictly control the crowd of transfusion speed and amount of infusion, can cause aggravation, have in addition threat to life.Infusion pump is a kind of effective ways that solve transfusion speed, adopts power extruding transfusion, and amount of infusion is certain within a certain period of time, but during dropping speed and inhomogeneous; And machine cost and consumables cost are too high, are only applicable to first aid and serious symptom situation.The stable performance of SJK type numeral transfusion monitoring instrument, easy to use, easy to operate, but price comparison is expensive, uses less.And at present the common transfusion pipe is dripped speed and detects and to mainly contain ultrasound examination, infrared detection, capacitance detecting, this type of detect to medicinal liquid whether influential also under study for action.And in the medical institutions in future, particularly in some large and medium-sized hospitals, when patient infusion, more and more higher with the requirement meeting of the order of accuarcy of transfusion numberical value of quantity to transfusion speed, therefore, be badly in need of a kind of appearance of not only practical but also cheap automatic drop controller product on the market.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provide a kind of simple and practical, use cost is low, and to medicinal liquid without any transfusion dripping controller radiation effect, control transfusion speed and amount of infusion by processing drop sound wave vibration signal.
To achieve these goals, this utility model has adopted following technical scheme: a kind of transfusion dripping controller based on the sound wave vibration signal comprises Acoustic Signal Acquisition device, control mainboard and accurate stepping clamping motor; The close contact face of described Acoustic Signal Acquisition device and Murphy's burette arranges vibrating diaphragm, is provided with film chamber and tract in the Acoustic Signal Acquisition device, and an end of tract communicates with the film chamber, and the other end is equipped with pick up; Pick up is connected with the control mainboard, and the control mainboard is connected with accurate stepping clamping motor line.
Be provided with data processing module and wirelessly transmitting data module in the described control mainboard.The control mainboard mainly is single-chip microcomputer, and indoor design has date processing, bandpass filtering algorithm process, storage, transmission supervisor.Data processing module and wirelessly transmitting data module all be in single-chip microcomputer with computer language editor's the functional program module with corresponding function, convert the electronic signal supervisor to as mainly having comprised bandpass filtering algorithm process, acoustic signals in the data processing module; The wirelessly transmitting data module has then mainly comprised the function program that realizes data processed result is transmitted through network coordinator the PC host computer.
Described wirelessly transmitting data module is ZigBee wireless network transmissions data module; Can realize with hospital in the ZigBee wireless network monitoring system carry out transfer of data.
The vibrating diaphragm that this utility model uses does not have too large requirement to material, as long as can cause the film of vibration, all can.
Pick up has the advantages that volume is little, simple in structure, electroacoustic performance is good, price is low, is widely used in the circuit such as cassette recorder, wireless microphone and acoustic control.As, Electret condenser microphone belongs to the most frequently used capacitor microphone.Because the input and output impedance is very high, so a field effect transistor will be set as impedance transducer in this microphone enclosure, electret capacitor microphone needs direct-current working volts when work for this reason.And the pick up of the present utility model function that need realize, do not need field effect transistor, only need the simple amplifier of acoustic signals amplified or audion amplifies and get final product.
Operation principle of the present utility model:
When the fluid drips in the infusion bottle is fallen Murphy's burette, after the generation sound wave is agitated the vibrating diaphragm of Acoustic Signal Acquisition device, the closed gas of film intracavity shakes thereupon, because tract is carefully narrow, the gas pulsation amplitude is just much larger than the amplitude of film intracavity, the sound wave vibrations that the drop drippage produces have been amplified thus, and frequency there is not change, detect with pick up (miaow head) this moment, after amplifying through bandpass filtering, sends into the control mainboard again, realization is converted to the signal of telecommunication by the sound wave vibrations, the control mainboard drips blanking time according to drop, through algorithm process, can obtain transfusion speed, again according to setting value relatively, control accurate stepping clamping motor to the clamping degree of tube for transfusion, reach control transfusion speed purpose, and then by the ZigBee wireless network data processed result is transferred to the PC host computer.
This utility model can use by monomer, also can unite use with ZigBee-network monitoring system in the hospital.In the ZigBee-network monitoring system, a plurality of transfusion dripping controller terminals of the present utility model can be transferred to PC host computer in the hospital via ZigBee router, ZigBee coordinator with the transfusion situation of each terminal, are convenient to hospital's unified monitoring, management.
Compared with prior art, the beneficial effects of the utility model:
1. this utility model is simple and practical, and control is accurate, and reliability is high, and capacity of resisting disturbance is strong, and production cost is low.
2. this utility model is controlled transfusion speed and amount of infusion by processing drop sound wave vibration signal, do not contact medicinal liquid or medicinal liquid carried out radiation, on the property of medicine of medicinal liquid without any impact.
