Description
Technical Field
The utility model relates to a from pushing-type electrostatic spinning syringe.
Background
A self-pushing type electrostatic spinning injector is an accessory of an electrostatic spinning machine. The electrostatic spinning is a method for preparing one-dimensional nanofiber materials, and in the spinning process, precursor liquid for electrostatic spinning is placed into a medical injector, a special injection device is used, the precursor liquid in the injector flows out from a needle, and the precursor liquid is stretched into one-dimensional nanofibers by using a high-voltage electrostatic field. Although the special injection device has good injection precision and uniform injection speed, the special injection device is expensive, has low precision requirement, is not willing to buy users of the special injection device, and has no substitute product.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned shortcoming, provide a from pushing-type electrostatic spinning syringe, it has mainly been solved at electrostatic spinning in-process, and is not high to the required precision, does not want to purchase the user of special injection device, does not have the problem of substitute product. The utility model aims at realizing the self-pushing type electrostatic spinning injector which comprises: the device comprises an electrostatic spinning needle head, an injector needle tube, an injector piston, a light compression spring, a spring bottom plate, an air bag, an injection rod, a vent pipe, an air release valve and a one-way inflation ball. The electrostatic spinning needle is connected with the syringe needle tube, the syringe piston is respectively connected with the light compression spring and the injection rod, the spring bottom plate is respectively connected with the light compression spring and the air bag, the air bag is connected with the vent pipe, the vent pipe is connected with the air release valve, and the air release valve is connected with the one-way inflatable ball.
The spring bottom plate is provided with a round hole, and the injection rod passes through the round hole.
The bladder has a cylindrical passage through which the plunger rod passes.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The best embodiment of the invention is described in detail below with reference to the accompanying drawings, a self-propelled electrospinning injector comprising: the device comprises an electrostatic spinning needle head 1, an injector needle tube 2, an injector piston 3, a light compression spring 4, a spring bottom plate 5, an air bag 6, a push injection rod 7, a vent pipe 8, an air release valve 9 and a one-way inflatable ball 10. The electrostatic spinning needle head 1 is connected with the injector needle tube 2, the injector piston 3 is respectively connected with the light compression spring 4 and the injection rod 7, the spring bottom plate 5 is respectively connected with the light compression spring 4 and the air bag 6, the air bag 6 is connected with the vent pipe 8, the vent pipe 8 is connected with the air release valve 9, and the air release valve 9 is connected with the one-way inflatable ball 10.
Further, a circular hole is formed in the spring bottom plate 5, the injection rod 7 passes through the circular hole, and the position of the injector piston 3 can be adjusted by the injection rod 7.
Further, the balloon 6 has a cylindrical passage allowing the plunger rod 7 to pass through the cylindrical passage, and the balloon 6 is sealed airtight.
The working principle of the specific embodiment is as follows: the injection rod 7 is pulled backwards to move the injector piston 3 backwards, the precursor liquid is sucked and filled into the injector needle tube 2, the one-way inflatable ball 10 inflates the air bag 6 through the vent pipe 8, the air release valve 9 releases the air in the air bag 6 so as to adjust the volume of the air in the air bag 6, and the position of the spring bottom plate 5 is adjusted by utilizing the volume of the air in the air bag 6 so as to adjust the pressure change caused by the change of the precursor liquid volume. The light compression spring 4 is used for providing pressure to push the injector piston 3 to move, so that the precursor liquid flows out through the electrostatic spinning needle head 1.
In the description of the present invention, unless expressly stated or limited otherwise, the term "connected" is to be understood in a broad sense, e.g. fixedly connected, detachably connected, or integral; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
