Description
Technical field
This utility model relates to flow detector, particularly the flow detector of medical pump (syringe pump and infusion pump).
Background technology
At present, the infusion pump detector of development adopt the COMSens patented technology mostly, but its certainty of measurement is lower both at home and abroad, and resolution is less, and is incompatible with the development of modern clinical treatment technology.
The utility model content
The purpose of this utility model provides a kind of medical injection pump and infusion pump detector with high accuracy and high-resolution flow measurement.
This novel purpose is achieved in that a kind of medical injection pump and infusion pump detector, comprises master controller, and the solenoid control unit that is connected with master controller is arranged on the electromagnetic valve on the export pipeline of medical pump, also has:
Decide volume transparent glass pipe: be arranged on the fluid passage of said medical pump;
Infrared Detectors: by 20 groups of infrared tubes, the signal output part of infrared tube connects signal amplification circuit filter in order and first A/D converter is formed, and the signal output part of first A/D converter is connected with said master controller;
Above-mentionedly decide volume transparent glass pipe and be positioned on the light path of 20 groups of infrared tubes.
Also have as the pressure transducer of gathering said medical pump outlet fluid pressure, the signal output part of pressure transducer is connected with second A/D converter and said master controller in order.
Compared with prior art, the utlity model has following characteristics: this medical injection pump and infusion pump (general designation medical pump) detector is to syringe pump and infusion pump flow measurement, and its measured value accurately and reliably.The important technological parameters of this device:
1) measuring range: 5 ml/h～1000 ml/h, allowable error ± 2%;
2) blockage pressure: 0 kPa～200 kPa, allowable error ± 1%;
3) resolving power: 0.001 mL/h.
The infusion pump detector that this utility model adopts the mode of measurement fluid volume to develop first has higher precision and higher resolving power.In addition, the syringe pump and the infusion pump detector that adopt the infrared tube Detection Techniques to process are a kind of easy for installation, and the flow detection instrument that maintenance cost is low can reach higher measuring speed, practice thrift gauger's Measuring Time.This flow detector not only certainty of measurement is higher, and cost is relatively low, and good real-time performance is arranged, and small amount of flow measuring is one well replenishes.
This utility model is that armarium manufacturer, Medical Measurements management unit, testing agency and hospital provide indispensable quality testing instrument, for promoting the medical industry development, guaranteeing that quality of medical care and effect play an important role.

The specific embodiment
Fig. 1 illustrates, this novel master controller that comprises, and the solenoid control unit that is connected with master controller is arranged on the electromagnetic valve on the export pipeline of medical pump, also has and decides volume transparent glass pipe: be arranged on the fluid passage of said medical pump; Infrared Detectors: by 20 groups of infrared tubes; The signal output part of infrared tube (be made up of transmitting tube and receiving tube by infrared tube; Tube-launched infrared signal is received the pipe reception through deciding behind the volume transparent glass pipe; Receiving tube can produce corresponding current signal according to the power of infrared light; Signal amplification circuit filter is exactly that this current signal is zoomed into bigger voltage signal for the subsequent conditioning circuit collection) connect signal amplification circuit filter and first A/D converter composition in order, the signal output part of first A/D converter is connected with said master controller; Above-mentionedly decide volume transparent glass pipe and be positioned on the light path of 20 groups of infrared tubes.Also have as the pressure transducer of gathering said medical pump outlet fluid pressure, the signal output part of pressure transducer is connected with second A/D converter and said master controller in order.
This utility model adopts the infrared tube Detection Techniques, through fixing the fixedly volume of liquid of two infrared tube spacings, only needs the time that the measurement fluid flows through two adjacent infrared tubes just can measure its flow velocity.It is to flow through the indirect flow rate of fluid of measuring of used time of fixed volume glass tubing through Fluid Computation.Instrument equidistantly is fixed on 20 groups of infrared tubes on the circuit printing plate, according to following formula:
(
,
represent fluid is flowed through between two adjacent infrared tubes volume and time respectively in the formula;
representes flow velocity) can know: when two infrared tube spacings fixedly the time;
in the formula is a fixed amount; The measure of time that measuring system only needs fluid to be flow through two adjacent infrared tubes is come out, and just can the flow rate of fluid measurement be come out according to formula again.The employed 20 groups of infrared tubes of system are exactly to be used for measuring fluid to flow through the measurement used time of glass tubing; When fluid does not flow through glass tubing; The infrared signal that system acquisition arrives a little less than, as fluid through the time, infrared ray will be because the optically focused effect of liquid will make that signal obviously strengthens; Central processing unit can calculate the required time of system according to the signal of these two significant changes, and then measures flow rate of fluid indirectly.Because the certainty of measurement of system requires high,, make the variable quantity of signal strengthen to improve certainty of measurement so will use the Infrared Detectors of good glass tubing of light transmission and high conformity.The medical injection pump of being developed adopts a main frame to be connected the mode of operation of four capture cards with the infusion pump detector; Can check the output flow of 4 infusion pump or syringe pump simultaneously; Connect through the RS485 bus between main frame and the capture card, realize the real-time transmission of data.Instrument adopts high-precision pressure sensor can measure the pressure of syringe pump and infusion pump output liquid accurately in addition.
