Embodiment 1

[0041] This embodiment provides an electrospinning device, such as figure 1 As shown, it includes a syringe barrel 1 , a push rod 3 , a blocking member 4 and a one-way throttle member 5 .

[0042]The end of the syringe barrel 1 close to the needle 2 is the first front end, and the stainless steel needle 2 is installed on the first front end opening of the syringe barrel 1 . The push rod 3 is a hollow structure with a hollow cavity. The hollow cavity is axially arranged through the push rod 3. The end of the push rod 3 close to the needle 2 is the second front end, and the end facing away from the needle 2 is the second rear end. Two ends of the push rod 3 respectively form a second front end opening and a second rear end opening.

[0043] Both the injection cylinder 1 and the push rod 3 are hollow cylinders. The outer diameter of the push rod 3 is larger than the radius of the injection body. When the operator presses the push rod 3, the contact area with the push rod 3 is la...

Embodiment 2

[0054] This embodiment provides an electrospinning device, see figure 2 and image 3 , which differs from Embodiment 1 in that the one-way throttle member 5 includes a plurality of baffles 51, the baffles 51 are fan-shaped petals, any baffle 51 has a fixed end and a free end, and the baffle is a rigid material The fixed end of the blocking piece is hinged on the end surface of the annular boss 31, the free end of the blocking piece is inclined and gathered inward toward the center line of the push rod 3, and the adjacent ends of any adjacent two blocking pieces 51 are pressed against each other. The plurality of blocking pieces 51 are pressed together to form a closed bud shape, and a second cavity protruding toward the needle head 2 is formed at the second front end of the push rod 3 .

[0055] When in use, the spinning solution is located in the first cavity, pushes the push rod 3, the free ends of the plurality of baffles 51 gather at the centerline of the push rod 3, the...

Abstract

The invention provides portable electrostatic spinning equipment. The portable electrostatic spinning equipment comprises a syringe, a push rod, a plugging component and a one-way throttling component, wherein the push rod is of a hollow structure, and the one-way throttling component is installed at a second front end of the push rod in a sealed mode. When spinning solution in a first cavity is used up, the push rod is pulled outwards to increase the volume of the first cavity, the plugging component is taken down from the push rod, the spinning solution is injected into a push rod hollow cavity through an opening in a second rear end of the push rod, the medium pressure in the hollow cavity is increased, the one-way throttling part is opened, and the spinning solution enters the first cavity from the push rod hollow cavity, so that injection or replacement of the spinning solution is achieved, and operation is easy and convenient; Besides, medicine powder such as anti-inflammatory medicine can be added into the push rod conveniently, the medicine powder is brought into the first inner cavity when the spinning solution is injected, and spun fibers with the medicine powder are deposited on a wound to facilitate inflammation diminishing and healing of the wound; the electrostatic spinning equipment is small in size and convenient to carry; and when in use, the spinning equipmentcan be conveniently moved along with the wound shape of a patient, the spun fibers are formed according to the shape of the wound, and thus wound healing is realized.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to a portable electrospinning device. Background technique [0002] Electrospinning is one of the simplest and most efficient methods for preparing one-dimensional micro-nanofibers. Compared with traditional nanomaterial preparation technology, it has the advantages of simple processing equipment, wide source of raw materials, low spinning cost, and large-scale preparation. It has received extensive research reports at home and abroad. Micro-nanofibers processed by electrospinning technology have excellent characteristics such as high specific surface area, large aspect ratio (ie length / diameter), and unique physical and chemical properties, and are widely used in biological tissue engineering, wound dressings, filtration protection, drugs. Slow-release, flexible devices and other fields show great application potential. The principle of electrospinning is as follows: unde...
