Problems solved by technology

[0013] However, when using the hemostatic pad of Patent Document 1, both sides of the pressing part are spherical convex surfaces, so it has the advantage of being easy to concentrate and strongly compress the puncture part, but there is also the following problem: when the needle is pulled out, the spherical convex There is no guide rail or groove for easy needle withdrawal on the shape surface, so in order to prevent blood from leaking out, more careful attention is required when pulling out the needle, and the workability is poor

Abstract

Provided are a hemostatic cotton compress with improved workability without loss of astriction effects when indwelling arteriovenous needles are used in artificial dialysis, injection, drip infusion, blood-drawing, etc. and the needle, etc. is withdrawn from the puncture site, and a production method therefor. The hemostatic cotton compress and production method therefor involve one-piece molding of a fibrous substance. The compress has a surface for compressing a specified hemostasis site and, forming a portion of said surface to be flat or curved, a portion of said surface is provided with a groove for engaging the needle or the plastic tube attached thereto.

Description

technical field [0001] The present invention relates to compression hemostatic cotton and its manufacturing method. [0002] In particular, the present invention relates to excellent operability when pulling out the injection needle as the inner needle and the plastic tube as the outer needle from the puncture part when using the arteriovenous indwelling needle for artificial dialysis, injection, drip, blood collection, etc. A hemostatic cotton compress that exhibits an excellent hemostatic effect at a puncture site and a method for producing the same. Background technique [0003] Conventionally, when pulling out an injection needle or the like from a blood vessel on the surface of the skin, sticking absorbent cotton or gauze to the puncture site, pressing it with fingers, and then covering it with tape or a bandage and pressing the vicinity of the puncture site to stop bleeding. [0004] In particular, when an indwelling needle for artificial dialysis or the like is pulle...
