Embodiment 1

[0036] Such as Figure 1-4 As shown, a high-flux narrow-mouth dialysis bag includes a strip-shaped tubular bag body 1 made of dialysis membrane, one end of the bag body 1 is open, and the other end is transversely along the width direction of the bag body 1 Folding and sealing, the bag body 1 is folded longitudinally in the length direction and forms a folding intersection area 2 with the above-mentioned horizontal folding sealing place, and the folding intersection area 2 is wound and fixed by a viscous substance 3 and passed through a hot-melt glue stick 4, paraffin wax or other hot-melt materials to wrap the viscous substance 3 for sealing and secondary fixing.

[0037] The method of using the dialysis bag is as follows: stretch the opening end of the bag body 1, and put the sample solution into the bag from the opening. Since the length direction of the bag body 1 has been folded, the side wall of the bag body 1 will follow the sample solution. After the sample solution i...

Embodiment 2

[0039] On the basis of the foregoing embodiments, as a further preferred solution: as Figure 1-4 As shown, the bag body 1 is folded longitudinally at least once in half or Z-shaped in the longitudinal direction. The specific folding process can be folded 1-2 times or more, depending on the number of folds allowed by the size of the bag body 1 .

Embodiment 3

[0041] On the basis of the foregoing embodiments, as a further preferred solution: as Figure 1-4 As shown, the caliber of the bag body 1 is 0.2cm-5cm, and the length of the bag body 1 excluding the folding intersection region 2 is 0.5cm-15cm. The bag body 1 adopts a structure similar to a long column whose length is greater than the width of the caliber, but the dialysis bag is not limited to small sizes. It can be understood that the dialysis bag is also suitable for large sizes, but compared with large sizes, this The beneficial effect that the dialysis bag is set to the small specification size is more obvious, and the material of bag body 1 is animal film or cellophane, or is the dialysis membrane that is made of cellulose, viscous substance 3 is adhesive tape, and described glue stick 4 is Adhesives with ethylene-vinyl acetate copolymer (EVA) as the main material.

Abstract

The invention provides a high throughput and narrow opening dialysis bag and a manufacturing method thereof, and relates to the technical field of biological dialysis equipment. The dialysis bag comprises a bag body which is in a strip-shaped pipe shape. One end of the bag body is opened, and the other end of the bag body is transversely folded and sealed in the width direction of the bag body. The bag body is longitudinally folded in the length direction, a folding intersection area is formed at the longitudinal folding and transverse folding sealed position, the folding intersection area is wound and fixed through sticky substances, and a hot melted glue stick is used for wrapping the sticky substances for sealing and secondary fixing. According to the manufacturing method, at least one-transverse and one-longitudinal folding is conducted on the bag body, transverse folding is conducted for sealing one end of the bag body, the width of the bag body is reduced through longitudinal folding, adhesive tape is used for winding and fixing, and hot melted substances are used for wrapping the adhesive tape. The diameter of the sealed end of the dialysis bag is far smaller than the width of the cross section of the dialysis bag, better ductility is achieved, the occupied space is smaller, and cost is lower; and the manufacturing method is simple and convenient to operate, and manual manufacturing can be conducted.

Description

technical field [0001] The invention relates to the technical field of biological dialysis equipment, in particular to a high-throughput narrow-mouth dialysis bag and a manufacturing method thereof. Background technique [0002] A dialysis bag is usually a bag-like container made of a semipermeable membrane. During the preparation of biomacromolecules, dialysis is used to remove salts, a small amount of organic solvents, impurities of small biomolecules and to concentrate samples. [0003] It has been more than one hundred years since Thomas Graham invented dialysis in 1861. Dialysis has become one of the easiest and most commonly used separation and purification techniques in biochemical laboratories. In the preparation process of biomacromolecules, dialysis technology is used to remove salt, remove a small amount of organic solvents, remove impurities of small biomolecules, and concentrate samples. Dialysis can be completed only by using a special semi-permeable membrane...
