Embodiment 1

[0052] refer to figure 1 , figure 2 and Figure 4 , an automatic decompression radial artery hemostat, mainly includes the following parts:

[0053] An annulus 1 set on the limb;

[0054] An annular airbag 10 fixed in the annular belt 1;

[0055] The hemostatic component 2 for radial artery hemostasis arranged on the inner ring surface of the balloon 10;

[0056] It communicates with the first trachea 11 fixed on the airbag 10, and the end of the first trachea 11 is disassembled and connected with the second trachea 12;

[0057] The third air pipe 13 and the fourth air pipe 14 connected at the end of the second air pipe 12 through a tee joint 15;

[0058] A pressure gauge 16 installed on the second air pipe 12;

[0059] An inflatable assembly 3 arranged at the end of the third air tube 13 for inflating the airbag 10;

[0060] communicate with the shell assembly 4 fixed at the end of the fourth air pipe 14;

[0061] And the automatic pressure relief assembly 5 arranged...

Embodiment 2

[0075] The difference from Example 1 is that a layer of hemostatic drug layer is fixed on the surface of the cotton pad 22. In order to increase the hemostatic effect and prevent the hemostatic patch 23 from still having a good hemostatic effect after the airbag 10 is inflated, the A layer of hemostatic drug layer is fixed on the surface of the cotton pad 22, so a preparation method of hemostatic drug is provided, which has the advantages of short preparation process, simple preparation, and convenient material selection, wherein the preparation method of the hemostatic drug layer is as follows:

[0076] Take the following ingredients by weight: 15 parts of agrimony, 15 parts of Artemisia argyi, 5 parts of heart soil, 5 parts of bletilla striata, 10 parts of purple pearl, 3 parts of small thistle, 3 parts of large thistle, 2 parts of jujube bark, 10 parts of notoginseng 2 parts of Anluoxue, 2 parts of Disodium Etarate, 40 parts of Agar;

[0077] S1. Drying and crushing: dry Ag...

Embodiment 3

[0082] The difference from Example 2 lies in the preparation of the hemostatic drug, wherein the preparation method of the hemostatic drug is as follows:

[0083] Take the following ingredients by weight: Agrimony 18 parts, Artemisia argyi 18 parts, Zaoxin soil 5 parts, Bletilla striata 5 parts, Purple Pearl 15 parts, Small thistle 5 parts, Big thistle 5 parts, Jujube bark 2 parts, Panax notoginseng 10 parts 2 parts of Anluoxue, 2 parts of Disodium Etarate, 43 parts of Agar;

[0084]S1. Drying and crushing: dry Agrimony, mugwort leaves, stove heart soil, bletilla striata, purple pearl, small thistle, large thistle, jujube bark, and Panax notoginseng, and then crush them to fine particles with a fineness of less than 20um;

[0085] S2, heating agar: heat the agar in a container until it melts;

[0086] S3. Mixed material: add the fine particles obtained in S1 into the heated agar and stir evenly to obtain a liquid agar-Chinese medicine mixture;

[0087] S4. Solidified hemosta...

Abstract

The invention discloses a radial artery hemostat capable of automatically reducing pressure. According to the main points of the technical scheme, the radial artery hemostat comprises a loop sleevinga limb, an airbag, a hemostatic assembly, a first air pipe, a third air pipe, a fourth air pipe, a pressure gauge, an inflation assembly, a housing assembly and an automatic pressure relief assembly,wherein the airbag is fixed in the loop and is in a ring form; the hemostatic assembly is arranged on an inner ring surface of the airbag and is used for performing hemostasis on a radial artery; thefirst air pipe is fixed on the airbag in a communicating manner; the end part of the first air pipe is detachably connected with a second air pipe; the third air pipe and the fourth air pipe are connected to the end part of the second air pipe through a tee joint; the pressure gauge is arranged on the second air pipe; the inflation assembly is arranged at the end part of the third air pipe and isused for inflating the airbag; the housing assembly is fixed at the end part of the fourth air pipe in a communicating manner; and the automatic pressure relief assembly is arranged in the housing assembly. The radial artery hemostat capable of automatically reducing the pressure can achieve a good hemostatic effect in use, and can achieve the target of automatic pressure relief.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to an automatic decompression radial artery hemostat. Background technique [0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. The radial artery is about 21.2cm long, and the outer diameter of its origin is about 0.3cm. After the branch of the brachial artery, it goes downward, first passes between the brachioradialis muscle and the pronator teres, then between the flexor carpi radialis and the brachioradialis muscle, and obliquely passes through the abductor pollicis longus and pollicus brevis at the lower end of the radius From the deep side of the extensor tendon to the back of the hand, it enters the nasopharyngeal fossa of Jiebuxue, passes through the space between the first metacarpal bone and enters the deep part of the palm, and after separating from the main thumb arter...
