Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. In practice, the invention will be understood to cover all modifications and variations of this invention provided they come within the scope of the appended claims.
For a better illustration of the invention, the following detailed description of the invention is given in conjunction with the accompanying drawings.
As shown in figure 1, the invention relates to a transfusion device based on a giant magnetostrictive driving film, which comprises a guide port 1, an upper shell 2, a motor pair lead 3, a planar spiral coil 4, an upper substrate 5, an upper insulating protective layer 6, a positive magnetostrictive film 7, an anti-slip ring 8, a lower insulating protective layer 9, a lower substrate 10, a lower shell 11 and the like. The planar spiral coil 4 is fixed in an upper insulating protective layer 6 and a lower insulating shell 9, the motor pair lead 3 is connected with the planar spiral coil 4 and an external driving power supply and used for supplying power to the coils, the substrates 5 and 10 are respectively arranged in the shells 2 and 11, the positive magnetic effect film material 7 is sprayed on one side of the substrate close to the infusion tube 12, the anti-skid ring 8 is embedded in the guide opening 1, and the infusion tube 12 is arranged between the upper shell 2 and the lower shell 11.
In the actual operation process, the working principle of the invention is as follows: the current with a certain frequency is introduced into the planar spiral coil 4, the planar spiral coil 4 generates a corresponding magnetic field under the action of the current, and the positive magnetostriction effect film 7 deforms under the action of an external magnetic field. When the current is increased, the magnetic field is increased along with the increase of the current, and the film 7 with positive magnetostriction effect is extended under the action of the external magnetic field, so that the upper substrate 5 and the lower substrate 10 are driven to bend inwards, and the infusion tube 12 is extruded to convey the medicine outwards; when the current led into the planar spiral coil 4 is reduced, the magnetic field is reduced along with the reduction of the current, and the positive magnetostrictive film 7 gradually recovers to the original length, so that the upper and lower substrates 5 and 10 are driven to recover to the original position, the pressure acting on the infusion tube 12 disappears, and the drug delivery stops. The process is repeated by continuously adjusting the current, so that the drug delivery is achieved.
Referring to fig. 2, the present invention is a kind of transfusion device based on giant magnetostrictive driving film, in the exploded view, the unified positions of the upper and lower cases 2 and 11 and the upper and lower substrates 5 and 10 are shown to be provided with screw holes, which are fastened by screws.
