Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to be more readily understood by those skilled in the art, so that the scope of the invention will be more clearly defined.

[0030] Please refer to attachment Figure 1 ~ 2 , A hemomdermaceous particle of an interventional puncture of the present invention, wherein the hemostatic particles consist of the following mass material:

[0031] Oxidized cellulose powder 1: 25 ~ 45%;

[0032] Avrid stops blood powder 2: 55 ~ 75%.

[0033] like Figure 4 As shown, a protective film 6 is adhered to the surface of the stopper particles 3, the protective film 6, which can be degraded in the blood, which can be absorbed by the human body, which is smooth, and the nutrient film comprises acetyl glucose. One of the amine film, polylactic acid film layer, polycaprolate film layer, polyterior hydrochexanone film layer, the thickness of the nutrient film is between ...

Abstract

The invention belongs to the medical supplies in the technical field of non-vascular system interventional therapy, and in particular relates to a hemostatic particle for interventional puncture and a preparation method thereof. The hemostatic particles for interventional puncture are composed of two hemostatic substances, oxidized regenerated cellulose and microfibrous collagen, which are uniformly mixed, refined and compressed at a ratio of about 4:6 by weight of the hemostatic substances to form cylindrical particles; they can be made into various sizes Particles meet the clinical needs of different puncture needle inner diameters. The hemostatic particle for interventional puncture of the present invention overcomes the needle tract bleeding caused after pulling out the puncture needle, avoids serious complications caused by bleeding after interventional puncture, and the oxidized regenerated cellulose and microfibrous collagen are non-toxic, non-teratogenic or Carcinogenicity, non-antigenicity and good compatibility with human tissue, it can be widely used in the hemostasis of interventional puncture needles. The protective film on the hemostatic particles can effectively prevent the hemostatic particles from being gelled, and the protective film can be degraded. Human body absorbs.

Description

Technical field [0001] The present invention belongs to a medical article in the art of non-vascular system interventional therapy, and involves an interventional puncture hemostatic particle and a preparation method thereof. Background technique [0002] With the rapid development of interventional radiology, interventional diagnosis and treatment technology is increasingly widely used, and related complications have also emerged. Through the transcotary puncture interventional treatment technology, after pulling out the puncture needle, hemorrhage is an important complications after surgery. If the bleeding is difficult to control, it may be necessary to further open the detection of blood, or even cause death due to blood loss shock. Therefore, it is of great significance for timely and effective hemostasis to interventional surgery. [0003] In recent years, medical absorbable hemostasis has attracted high attention from the medical circles and industry in various countries, ...
