Specific embodiment
The preferred technical solution of the utility model is described further with reference to the accompanying drawings and examples.
Embodiment, as shown in Figure 1: a kind of electro-medical magnetic-type infusion pump includes solenoid 1, the pump housing 2, silk plug 3, spring
4, permanent magnetism traveller 5, block 6, elastic membrane 7 and film valve perfusion tube 8, the solenoid 1 are wrapped in 2 outside left part of the pump housing, the pump
Cavity is equipped in body 2, cavity includes left chamber and right chamber, and it is sliding that silk plug 3, spring 4, permanent magnetism are from left to right successively arranged in the left chamber
Column 5 and block 6, the silk plug 3 are connect with left chamber inner thread, and the silk plug 3 is connect by spring 4 with permanent magnetism traveller 5, described
Block 6 is fixedly connected with left chamber inner wall, and the permanent magnetism traveller 5 is slidably connected with left chamber inner wall, and permanent magnetism is sliding under the effect of spring 4
5 a part of column is stuck in left chamber, and another part extend out to right chamber, 5 extension end of permanent magnetism traveller and the elastic membrane 7 being socketed in right chamber
Crimping, the elastic membrane 7 are socketed with film valve perfusion tube 8.
Preferably, coil is wound on the solenoid 1.
Preferably, the 2 left chamber left end of the pump housing is provided with closely-pitched internal screw thread.
Preferably, the block 6 at least 2.
Preferably, the block 6 has 4 for progress one.
Preferably, the elastic membrane 7 is hollow cylindrical.
Preferably, 7 material of elastic membrane is rubber.
Preferably, 8 both ends of film valve perfusion tube are equipped with diaphragm type one-way valve, including connect with 8 input terminal of film valve perfusion tube
The input diaphragm formula check valve 91 connect and the output film formula check valve 92 being connect with 8 output end of film valve perfusion tube, the input
91 input terminal of diaphragm type one-way valve is connect with input perfusion tube 93, and 92 output end of output film formula check valve and output are infused
Pipe 94 connects.
Working principle are as follows: when 1 no power of solenoid, under the elastic force effect of spring 4,5 right end of permanent magnetism traveller presses bullet
Property film 7 and film valve perfusion tube 8, when 8 input terminal of film valve perfusion tube is balanced with output end pressure, input diaphragm formula check valve 91 and defeated
Diaphragm type one-way valve 92 is in closed state out, at this time in closing, 8 chamber of film valve perfusion tube in 8 chamber of film valve perfusion tube
Inner volume is V1, which is in readiness for operation.When 1 indirect current of solenoid, under the action of Lorentz force, forever
Magnetic traveller 5 has the tendency that compressed spring 4 to the left, when the sum of Lorentz force and 7 elastic restoring force of elastic membrane are greater than the elastic force of spring 4
When, permanent magnetism traveller 5 moves downward, and 5 right end of permanent magnetism traveller leaves elastic membrane 7, and when permanent magnetism traveller 5 is moved downward to block 6
When setting, stop motion, 8 chamber inner volume of film valve perfusion tube increases Δ V at this time, and 8 cavity indoor pressure of film valve perfusion tube is less than input
