Problems solved by technology
But despite this, these pumps also have certain deficiencies. For example, a larger rotor system usually needs to be set in their pump chambers, which makes the pump structure more complicated.
In particular, the rotor system is usually in direct contact with the fluid (such as impeller pumps, gear pumps), which greatly increases the possibility of fluid contamination, which also restricts its application in the medical field

Embodiment
[0040] Example:The best embodiment of the present invention is designed as a structure with two pump chambers 1, and a closed high-elastic diaphragm 4 is provided in each of the two pump chambers 1 to change the volume of the pump chamber 1. The main purpose of each pump chamber 1 is to increase the suction force and pumping capacity of the pump, and can make up for the insufficient output power of the artificial muscle sheet 5 . If the displacement of the pump is to be increased, the pump may be configured with three or more pump chambers 1 as appropriate. The driving voltage of the electrically actuated artificial muscle pump is less than 10V.
[0041] attached Figure 4 The pumping state of the artificial muscle pump based on electric actuation is given. It can be seen from the figure that in order for the pump to suck the fluid into the pump chamber 1 from the accumulator tank, the electric control check valve A 6 must be energized first to open the inlet of the guide ...

The invention discloses an electric actuating artificial muscular pump and a control method thereof. A pump cavity is externally provided with a support; one end of the pump cavity is connected with a flow guide pipe, and the other end of the pump cavity is connected with a pump cover; a diaphragm is clamped in the combining surface of the pump cavity and the pump cover; artificial muscular plates are installed at one side of the diaphragm close to the pump cover; an electric control check valve A is connected with the inlet of the flow guide pipe; an electric control check valve B is connected with the outlet of the flow guide pipe; the flow guide pipe at the electric control check valve B is provided with an energy storage device; and the artificial muscular plates, the electric control check valve A and the electric control check valve B are connected with a driving controller through a wire. When the pump operates, certain types of alternating voltages with equal amplitudes and shared frequencies are applied to each artificial muscular plate through the driving controller so as to excite the artificial muscular plates to perform buckling vibration, and the elastic diaphragm is driven by the vibration to perform contraction and expansion motions, thus the volume of the pump cavity is changed, and the pumping function is realized.
Description
[0001] Technical field [0002] The invention involves a fluid pump, which is a variable -loading pump field in the mechanical pump. Specifically, it is a small flow pump that uses electrophoretic strain effects that use electrical electrical muscles to achieve the function of the fluid pumping function.Moving artificial muscle pump and its control method. technical background [0003] Medical fluid transportation device is an important medical appliance that plays an extremely important role in medical operations and surgery.For example, in the laparoscopic examination and endoscopic examination, the fluid pump is needed to transport drugs to the affected area. In hemodialysis or cardiac surgery, it is also necessary to use the pump to hemodialysis or artificial cardiopulmonary machine to transport blood. In addition, the pump is often often pump.Used to collect human body fluid for medical analysis.At present, most medical pumps use positive displacement pumps and centrifugal p...
