Embodiment 1

[0021] Embodiment 1: As shown in the accompanying drawings, a device for preparing a medical tubular stent, including a support frame 1 made of 1060 series aluminum alloy plates fixed on an electrospinning machine, made of 316 grade stainless steel The automatic roller 2 that can be easily replaced is installed on the support frame 1. The two sides of the automatic roller 2 that can be easily replaced are installed with 0-45° radial bearings, forming a rolling fit relationship with the support frame 1 . Both the automatic roller 2 that can be easily replaced and the cylindrical drum 3 on the electrospinning machine are connected with the support frame 1 . The automatic roller 2 that can be easily replaced rotates synchronously with the cylindrical rotating drum 3 through a belt transmission mechanism. A "U"-shaped groove 9 is set on the support frame 1, which can realize the forward and backward movement of the support frame 1, and adjust the distance between the automatic ro...

Embodiment 2

[0022] Embodiment 2: As shown in the accompanying drawings, a device for preparing a medical tubular stent includes a support frame 1 made of an aluminum alloy plate Z17LSI12 fixed on an electrospinning machine, and the support frame 1 installed on the support frame 1 can be easily The replacement automatic roller 2 is made of 316L grade stainless steel. 30-60° radial bearings are installed on both sides of the automatic roller 2, which can be easily replaced, and form a rolling fit relationship with the support frame 1. In order to realize easy disassembly and installation of different automatic rollers, spring bayonets are used to fix the automatic rollers, and the two ends of the rollers are directly inserted into the square bayonet grooves with springs. A "U"-shaped groove 9 is set on the support frame 1, which can realize the forward and backward movement of the support frame 1, and adjust the distance between the automatic roller 2 that can be easily replaced and the cyl...

Embodiment 3

[0023] Embodiment 3: As shown in the accompanying drawings, a device for preparing a medical tubular stent includes a support frame 1 made of light aluminum alloy 7075 fixed on an electrospinning machine, and a support frame 1 that can be installed on the support frame 1. The easy-to-change automatic roller 2 is made of 316L stainless steel. 15-60° radial bearings are installed on both sides of the automatic roller 2, which can be easily replaced, and form a rolling fit relationship with the support frame 1. In order to realize the automatic disassembly of the automatic roller and the easy replacement of unused rollers, the IC32B80-SF1FAY cylinder is used to fix it with bayonet pins. The two ends of the rollers are directly inserted into the bayonet slots of the hexagonal cylinder. The connecting rod extends so that the bayonet pins hold the ends of the rollers. When replacing the roller, the solenoid valve sends out a signal, the cylinder does not work, the cylinder connecti...

Abstract

The invention discloses a device for preparing a medical tubular support, and relates to a device for preparing a medical tubular nanofiber membrane support. It includes support frames fixed on both sides of the electrospinning machine, and automatic rollers that can be easily replaced; the automatic rollers that can be easily replaced and the cylindrical drum on the electrospinning machine are all compatible with the support frame. Connected, the automatic roller that can be easily replaced, rotates synchronously with the cylindrical drum through the transmission mechanism. A "U"-shaped groove is provided on the support frame to facilitate adjustment of the distance between the automatic roller and the cylindrical drum. The two ends of the automatic roller are provided with movable connection devices for easy replacement of the roller. The device of the invention can prepare medical tubular nanofiber membrane supports and their coatings with different calibers and multiple uses at one time, can quickly change varieties, and reduce production time and costs. The device has simple structure, easy operation and use, and low maintenance cost.

Description

technical field [0001] The invention relates to a device for preparing medical tubular textiles by using electrospinning technology, in particular to a device for preparing medical tubular nanofiber membrane support and nanofiber coating at one time. Background technique [0002] There are various pipelines in the human body, such as esophagus, trachea, blood vessels, nerves, hepatic ducts, genitourinary ducts, etc. When these pipeline tissues in the human body become diseased, corresponding treatment must be carried out, and repair and replacement operations should be carried out if necessary. Medical tubular stent is a kind of biomedical textile prepared by technicians through physical, chemical, biological and other methods according to the pipeline transplantation objects in different parts of the human body. [0003] Electrospinning is one of the low-cost and high-efficiency methods for preparing nanofibers. The nanofibrous scaffold prepared by electrospinning has the...
