Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, the high-pressure air source in the solution jet spinning is usually generated by a high-pressure air pump, and the high-pressure air pump has a complex structure and usually needs to be connected with a power supply, so that the solution jet spinning is not easy to carry or use. For example, in the medical field, it may be desirable to prepare wound dressings in the field using solution jet spinning in order to protect the wound, accelerate wound blood clotting and healing. However, the use of high pressure air pumps is obviously not suitable for field operations. Based on this, the embodiment of the present application provides a portable solution jet spinning device, which is described in detail below.
Referring to fig. 1, a schematic structural diagram of a solution jet spinning apparatus provided in an embodiment of the present application is shown. As shown in fig. 1, the portable solution jet spinning device provided by the embodiment of the present application includes a high pressure gas tank 100 and a spinning solution injector 200; the high-pressure gas tank 100 comprises a tank body 101 and a gas tank switch 102, wherein the tank body 101 is used for containing compressed gas, and the gas tank switch 102 is used for opening the tank body 101 to enable the compressed gas to be sprayed out from an opening of the tank body 101; the spinning solution injector 200 comprises an injector body 201 and a propeller 202, the injector body 201 and the propeller 202 form an accommodating cavity for accommodating a spinning solution, and when the propeller 202 moves relative to the injector body 201, the volume of the accommodating cavity changes, so that the spinning solution is ejected or sucked at an opening of the injector body 201.
Specifically, an injection tube 103 is arranged at an opening of the tank 101, and an injection tube 203 is arranged at an opening of the injector body 201. When the spinning solution injector is used, a user pushes the air tank switch 102 and pushes the propeller 202 of the spinning solution injector 200 at the same time, so that the jet pipe 103 jets high-speed airflow, the spinning solution flows out from the injection pipe 203, the spinning solution is stretched and refined under the action of the high-speed airflow, and finally the nano fibers are obtained along with the volatilization and solidification of the solvent.
It is understood that, in the case of performing the solution jet spinning, the opening of the injection pipe 203 of the spinning solution injector 200 needs to be located at the opening of the injection pipe 103 of the high pressure gas tank 100 so that the high speed gas flow can act on the spinning solution. On the contrary, if the high-speed air flow is not blown to the spinning solution, it is obvious that the jet spinning of the spinning solution is not performed or the spinning effect is desirable. The embodiment of the present application also improves the syringe 203 for ease of handling.
Referring to fig. 2, a schematic structural diagram of another solution jet spinning apparatus provided in the embodiments of the present application is shown.

In an alternative embodiment, the angle between the first tube 2031 and the second tube 2032 is 135 °.
In addition, for the convenience of use, a positioning hole or a positioning mark may be provided on the injection tube 103, and when in use, the user inserts the second tube 2032 into the injection tube 103 from the positioning hole or the positioning mark, so that the injection tube 103 and the injection tube 203 can obtain a proper matching position, and the operation is convenient. It will be appreciated that when the injection tube 103 is provided with a positioning hole, the size of the positioning hole should match the outer diameter of the injection tube 203 to prevent air from leaking out of the positioning hole during use, and in this case, the injection tube 103 may be a rigid tube or a flexible hose. When the positioning mark is provided on the injection tube 103, the injection tube 103 should be a flexible tube and the injection tube 203 should be a rigid tube so that the injection tube 103 is pierced by the injection tube 203 at the positioning mark.
In an alternative embodiment, the diameter a of the injection tube 103 is 2-3.5mm, the diameter b of the second tube 2032 of the injection tube 203 is 0.3-0.7mm, and the distance c that the open end of the second tube 2032 extends out of the open end of the injection tube 103 is 2-3 mm.

The tank 101 is used for containing compressed gas with the pressure of 0.4-1.0 MPa. It is understood that the shape and size of the tank 101 and the pressure of the contained compressed gas can be set by those skilled in the art according to actual needs, and the present application does not limit the shape and size specifically. However, the tank 101 is not necessarily too large for the portability of the solution jet spinning apparatus.
To further improve the operability of a solution jet spinning apparatus. In an alternative embodiment, an inner sleeve 1032 is integrated within the ejector tube 103. Referring to fig. 3, a partial structure diagram of an injection pipe 103 according to an embodiment of the present application is provided.

Preferably, a portion of the inner sleeve 1032 near the first opening is coaxially disposed with the outer jet tube 1031 to obtain a better spinning effect.
It is understood that in the injection tube 103 shown in fig. 3, the inner sleeve 1032 corresponds to the second tube 2032 in the embodiment shown in fig. 2, and specific parameters of the inner sleeve 1032 in the embodiment shown in fig. 3 can refer to the second tube 2032 in the embodiment shown in fig. 2, which is not described herein again.
It should be noted that the spinning solution in the spinning solution injector 200 is not limited in the present embodiment. Those skilled in the art can make corresponding configuration according to actual needs. For example, a 10 wt% ethanol solution of polyvinyl butyral (PVB) is selected as the spinning solution, 1 g of PVB powder is mixed with 9 g of absolute ethanol, then the mixture is magnetically stirred for 2 hours at room temperature, and then the mixture is kept still for 0.5 hour, so that a uniform and transparent 10 wt% PVB electrostatic spinning precursor solution is obtained.
