Specific embodiment:

Below with reference to embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands the utility model Content, therefore, the cited case are not intended to limit the protection scope of the utility model.

Referring to Fig. 1, Fig. 2, a kind of Automatic-boosting infusion device, including pressure bag 2, perfusion tube 7 is provided on perfusion tube 7 Pressure switch 5 further includes air bag 1, pressure sensor 9, liquid level sensor 8, ultrasonic flow sensor 6, electronic fills exhaust pump 4 With PLC controller 10, pressure bag 2 and pressure sensor 9 are separately positioned in air bag 1, air bag 1 by charge and exhaust pipe 3 with it is electronic The connection of exhaust pump 4 is filled, liquid level sensor 8 is arranged in infusion bag 2, and ultrasonic flow sensor 6 is arranged on perfusion tube 7, pressure Power switch 5, pressure sensor 9, liquid level sensor 8, ultrasonic flow sensor 6, the electronic exhaust pump 4 that fills are controlled with PLC respectively Device 10 is electrically connected.

PLC controller 10 realizes the input flow rate of liquid, setting and control to fluid pressure, 10 basis of PLC controller It includes inflation power that clinic, which needs, pressure setting, actual pressure is shown, total amount of liquid is shown, liquid input quantity, low liquid level acousto-optic Totally seven unit compositions, all setting value errors exceed numerical value, number flashing report in ± 2% for alarm, CPU number Cheng Xu control Alert prompt (optoacoustic is changeable), PLC controller 10 needs to inflate to air bag 1 according to setting value, and required pressure value is flowed according to actual measurement Rate feedback stops supplying to gas cell 1 to PLC controller 10 close to the 90% of setting highest duty pressure, if not up to flow rate Setting value light flash prompts that the KB limit of 1 pressure of air bag should be adjusted, if flow rate reaches setting in range of set value Flow rate, the electronic exhaust pump 4 that fills stop inflating to air bag 1, maintain positive and negative the 5% of pressure, keep the stability of flow rate.

Pressure sensor 9, ultrasonic flow transducer 6, liquid level sensor 8 detect more than setting maximum value, stop to Air bag 1 is inflated and depressurizes the 10% of 1 pressure set points of air bag.

PLC controller 10 provides gas source by controlling the electronic exhaust pump 4 that fills to the inflation of air bag 1 according to setting numerical value, and picks up Pressure force snesor 9,8 data of liquid level sensor are compared, and total amount of liquid issues instructions to electronic fill less than 25% set amount Exhaust pump 4 is inflated to air bag 1, and when not meeting total amount of liquid less than 25% set amount, the electronic exhaust pump 4 that fills stops working, to liquid When surface pressing numerical value reaches setting pressure, the electronic exhaust pump 4 that fills stops supplying and maintains setting pressure, to liquid surface pressure Numerical value precision in the range of ± 1% adjusts, and maintains fluid bag surface pressure numerical value, ultrasonic flow sensor 6 is according to perfusion tube 7 Diameter detects fluid flow numerical value, and will test data and be sent to PLC controller 10, manually adjust fluid flow numerical value and show Show, realizes the intelligent management of input fluid flow.

PLC controller 10 is issued according to the setup parameter control section number Cheng Xu and is instructed, and provides gas by the electronic exhaust pump 4 that fills Source rushes vapour to air bag 1, and liquid is generated pressure by the pressure conduction of air bag 1 in the pressure bag 2 in air bag 1, realizes liquid input streams Rate reaches setting value, and the CPU number Cheng Xu that 1 pressure sensor 9 of air bag detects pressure data feedback PLC controller 10 controls single Member, finely tuning pressure in air bag 1 ensures that pressure is constant in air bag 1, realizes the stability of Liquid output stream rate.

It is the device center, PLC controller 10 that ensure that the input flow rate of liquid is stablized, in control air bag 1, pressure is constant The data such as amount, which are owed, to pressure, residual liquid quantity, super flow rate, over pressure, liquid in liquid input streams rate, air bag 1 realizes integral tube Reason meets the needs for carrying out a large amount of additive liqs to patient in clinical operation and first aid.

To ensure that it is safe that equipment clinical uses, the present apparatus is using gas-pressurized and 2 isolation method of pressure bag, only by filling row Tracheae 3 is inflated into air bag 1 realizes gas pressure conveying, the pressure being equipped in the passback air bag 1 of pressure sensor 9 in air bag 1 Data are to PLC controller 10, electronic to fill the starting of exhaust pump 4 and ensure that the input flow rate of liquid is steady when pressure data error is greater than 5% Dingan County is complete.

The course of work:

10 power initiation Auto-Sensing Mode of PLC controller detects pressure sensor 9, ultrasonic flow transducer 6, level sensing After device 8, working condition, self-test pass through, user of service can set required liquid flow rate, set liquid flow rate maximum value, set gas The CPU number Cheng Xu control unit of 1 the blowing pressure maximum value of capsule, PLC controller 10 calculates liquid according to set numerical value The blowing pressure of air bag 1 needed for flow rate realizes the stabilization of liquid flow rate, and adjusting range is positive and negative 5%

According to the 90% of the flow rate maximum value of setting, pressure sensor 9 and ultrasonic flow transducer 6 will test signal feedback It is transferred to PLC controller 10 and is computed and stopped by the electronic exhaust pump 4 that fills to 1 inflating pressure of air bag, and automatic pressure-reducing 10% is pressed Power maintains the flow rate of decompression 10%, and liquid level sensor 8 detects that amount of liquid reaches minimum, and PLC controller 10 issues instruction, electricity The dynamic exhaust pump 4 that fills stops inflating to air bag 1.

Immediately by 1 gas discharge recovery of air bag to atmosphere natural pressure.

Pressure sensor 9,6 detection data of ultrasonic flow transducer exceed setting value ± 10%, and liquid level sensor 8 detects Low liquid level, the acousto-optic warning unit starting of PLC controller 10.
