After the position signalling of the second iron core 17, by control circuit control towards different coil blocks 20 DC current flow when
Between and direction so that the first iron core 15 and the second iron core 17 do reciprocating linear motion according to the frequency of setting, so that first
The working chamber 14 of working chamber 13 and second is stretched and compressed according to the frequency of setting.
Below in conjunction with the accompanying drawings 3, accompanying drawing 4 illustrates the operation principle of electromagnetic drive pump 100.
Process one, as shown in figure 3, two coil blocks 20 are separately fixed on the left part pipe and right part pipe of pump housing pipe 11,
After energization, coil block 20 is produced and the pole orientation identical magnetic field of magnetic part 12, in left part pipe and right part pipe
First iron core 15 and the second iron core 17 are magnetized, and the first iron core 15 and the second iron core 17 have and magnetic portion as interim magnet
The near-end identical magnetic pole of part 12, thus both are mutually exclusive, with speed v to left movement, the second iron core 17 is with speed for the first iron core 15
Degree v is moved right.Because the first iron core 15 and the second iron core 17 are glued with the first adjusting rod 161 and the second adjusting rod 181 respectively
Connection, the first adjusting rod 161 and the second adjusting rod 181 are threadedly coupled with the first traction tube 162 and the second traction tube 182 respectively,
So the first iron core 15 and the second iron core 17 drive the first working chamber 13 and the second working chamber 14 to flex outward respectively this moment.First
The cavity volume of the working chamber 14 of working chamber 13 and second becomes big so that inside produces negative pressure, goes out closed check valve, enters check valve and beats
Open, liquid is flowed into the first working chamber 13 from the first connection inlet pipe 131, the second working chamber 14 is flowed into from the second connection inlet pipe 141
It is interior, until the first working chamber 13, the second working chamber 14 are stretched to the state of maximum.
Process two, as shown in figure 4, two coil blocks 20 are separately fixed on the left part pipe and right part pipe of pump housing pipe 11,
After energization, coil block 20 is produced and the different magnetic field of the pole orientation of magnetic part 12, in left part pipe and right part pipe
First iron core 15 and the second iron core 17 are magnetized, and the first iron core 15 and the second iron core 17 have and magnetic portion as interim magnet
The different magnetic pole of the near-end of part 12, thus both attract each other, the first iron core 15 is moved right with speed v, and the second iron core 17 is with speed
Degree v is to left movement.Because the first iron core 15 and the second iron core 17 are glued with the first adjusting rod 161 and the second adjusting rod 181 respectively
Connection, the first adjusting rod 161 and the second adjusting rod 181 are threadedly coupled with the first traction tube 162 and the second traction tube 182 respectively,
So the first iron core 15 and the second iron core 17 drive the first working chamber 13 and the second inwardly compression of working chamber 14 respectively this moment.First
The cavity volume of the working chamber 14 of working chamber 13 and second diminishes so that internal pressure is raised, and goes out check valve opening, enters check valve pass
Close, liquid flows out the first working chamber 13 from the first connection outlet pipe 132, flow out the second working chamber 14 from the second connection outlet pipe 142, directly
The state of minimum is compressed to the first working chamber 13, the second working chamber 14.
Control module control electric current repeats said process 1 and is powered to corresponding coil block 20 to process 2, electromagnetic drive pump
100 can just beat pump blood, until control module sends instruction and stops being powered.
As shown in figure 5, when electromagnetic drive pump 100 is applied to extracorporal circulatory system, the first working chamber 13 and second of both sides works
The synchronous alternating contractions diastole in time in chamber 14, blood flows into the first working chamber from the connection inlet pipe 131 of vein first of patient
In 13, flow out the first working chamber 13 from the first connection outlet pipe 132 and reach storage blood pool by oxygenator, from the second connection inlet pipe 141
Flow into the second working chamber 14, the artery of patient is input into from the second connection outflow the second working chamber 14 of outlet pipe 142, complete the similar heart
The function of dirty each cavity pump blood.
The effect of embodiment and effect
Electromagnetic drive pump according to involved by the present embodiment, including the pump housing, the coil block that is arranged in the pump housing and with
The connected control unit of coil block.
The electromagnetic drive pump that the present embodiment is provided passes through electromagnetic coupled action principle, in being compressed using magnetic field force or being stretched
Empty screw thread tube chamber, so as to drive the pump housing integrally alternately to be shunk and diastole.The electromagnetic drive pump is applied into medical treatment to set
Pulsation type blood pump is manufactured into standby technical field, compared with common roller pump and centrifugal pump, due in whole pump liquid process
In rigid extruding force is not applied to liquid, reduce the damaged condition caused to liquid, the continuous filling of centrifugal pump can be avoided
Damage of the note pump blood to tissue internal organs and brain.
In addition, adjusting the first iron core, the second iron core and permanent magnet by first adjusting rod the second adjusting rod screw thread rotation
Distance, the first iron core, the movement travel of the second iron core can be changed, so as to reach the first working chamber of control and the second working chamber
Pump liquid amount.
Further, using elastomeric flexible and the medical high polymer of good biocompatibility with good fatigue resistance
The cannulated threaded tubular type cavity that material is made, inner wall smooth can largely prevent the injury to haemocyte, be applied to body
During outer circulation, the pulse blood pressure of generation can improve peripheral circulation, improve the oxygen supply of brain.
Above-mentioned implementation method is preferred case of the invention, is not intended to limit protection scope of the present invention.
