Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical hemostats, in particular to a radial artery compression hemostatant. Background Art
[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 21.2 cm long and has an outer diameter of about 0.3 cm at the beginning. After the brachial artery is separated, it runs outward and downward, first passing between the brachioradialis and pronator teres, then between the radial flexor carpi and the brachioradialis, to the lower end of the radius, obliquely passing through the deep surface of the tendons of the abductor pollicis longus and extensor pollicis brevis to the back of the hand to enter the anatomical nasopharyngeal fossa, and then passing through the first metacarpal space to enter the deep part of the palm. After the main thumb artery is separated, it anastomoses with the deep palmar branch of the ulnar artery to form a deep palmar arch. The radial artery is located shallowly between the lower end of the radius and the radial flexor carpi tendon, making it an ideal site for palpation and puncture. The radial artery is accompanied by two constant veins. A straight line is drawn from 2.5 cm below the center of the cubital fossa to the inside of the radial styloid process. This is the radial artery.
[0003] Transradial coronary intervention has become the main method for treating coronary heart disease worldwide, and the number of patients undergoing transradial artery puncture has increased dramatically each year. In the early stage, many people used manual finger pressure and bandage, which is an empirical method of hemostasis. If the pressure is too low, it is easy to bleed; if the pressure is too high, it is easy to cause poor blood flow and numbness of the fingers; and it is difficult to maintain a stable pressure during implementation, resulting in hemostasis failure, and the need to press again to stop bleeding, which increases the workload of medical staff and the pain of patients.
[0004] Currently, the devices for radial artery hemostasis on the market mainly include balloon compression type, spiral compression type, etc. The compression device with a single structure has poor adjustment performance when in use, and it is difficult to adjust the degree of compression on the radial artery. In this regard, a radial artery compression hemostat that is easy to adjust and disassemble is proposed. Utility Model Content

[0025] Through the above structure, the rotating block 13 drives the rotating shaft 11 to rotate, and the threads 12 on the outside of the rotating shaft 11 cooperate with the threaded tube 8 to realize the up and down movement of the rotating shaft 11, thereby driving the pressing plate 9 and the airbag 10 to move up and down. When the threads 12 are separated from the threaded tube 8, the rebound force of the spring 14 can quickly move the pressing plate 9 and the airbag 10 away from the radial artery, which is convenient for the subsequent disassembly of the compression hemostat. The specific structure is as follows:
[0026] Combined with Figure 3 As shown, the rotating shaft 11 is fixedly connected to the upper side wall of the cover body 7 , and the upper part of the spring 14 is located inside the cover body 7 .
[0027] Through the above structure, the cover body 7 is driven by the rotating shaft 11 to move downward at the same time, and the spring 14 is compressed by the cover body 7.
[0028] Combined with Figure 3 As shown, a round tube 15 is installed on one side of the pressure plate 9, and the upper end of the round tube 15 slides through the pressure regulating plate 1. An air guide tube 16 connected to the airbag 10 slides through the inside of the round tube 15, and a sealing cover 17 is installed on the other end of the air guide tube 16.
[0029] Through the above structure, the circular tube 15 slides through the inside of the pressure regulating plate 1 to limit the pressure plate 9 and prevent the pressure plate 9 from rotating with the rotating shaft 11. The air guide tube 16 passes into the inside of the circular tube 15 to prevent the air guide tube 16 from being bent and damaged. The airbag 10 is supplied with air and exhausted through the air guide tube 16, and the air guide tube 16 is sealed by the sealing cover 17.
[0030] Embodiment 2
[0031] Based on Example 1, please refer to the attached Figure 1 and attached Figure 2 The adjusting belt 3 includes an elastic belt 3.1, one side of the elastic belt 3.1 is connected to a Velcro 1 3.2, the other end of the Velcro 1 3.2 is connected to a matching Velcro 2 3.3, two groups of mushroom head nails 3.4 are arranged on the outer side of the Velcro 1 3.2, and a plurality of guide holes 3.5 for matching the mushroom head nails 3.4 are arranged on the Velcro 2 3.3, a U-shaped groove 4 is installed on the side of the positioning plate 2 away from the pressure regulating plate 1, a connecting rod 5 is connected between the two side walls of the U-shaped groove 4, one side of the elastic belt 3.1 is sleeved on the outer side of the connecting rod 5, and the Velcro 1 3.2 passes through the U-shaped groove 4 and is wrapped around the outer side of the connecting rod 5.
[0032] Through the above structure of the second embodiment, the pressure regulating plate 1, the positioning plate 2 and the adjusting belt 3 are wrapped around the outside of the arm through the cooperation of the Velcro 1 3.2 and the Velcro 2 3.3, and the compression hemostat has a slight elastic force through the elastic belt 3.1 to prevent excessive pressure on the arm, which may easily cause poor blood flow and numbness of the fingers. After the Velcro 1 3.2 and the Velcro 2 3.3 are used many times, the adhesion is easily reduced. By passing the two groups of mushroom head nails 3.4 through the guide hole 3.5, the stability of the compression hemostat is ensured.
[0033] The specific usage is as follows:
[0034] When the radial artery needs to be compressed, the pressure regulating plate 1, the positioning plate 2 and the adjusting belt 3 are wrapped around the outside of the arm, and a sufficient amount of gas is sent into the airbag 10 through the air guide tube 16 to expand the airbag 10, and the rotating block 13 is pushed downward to move the thread 12 to the threaded tube 8, and the rotating block 13 is rotated to drive the rotating shaft 11 to rotate, and the rotating shaft 11 is moved downward through the cooperation of the thread 12 and the threaded tube 8, and the cover body 7 is driven to move downward through the rotating shaft 11 and compress the spring 14, and the pressing plate 9 and the airbag 10 are pushed downward through the rotating shaft 11, and the radial artery is compressed in all directions through the airbag 10;
[0035] When the radial artery needs to be relieved of compression, the first way is to open the sealing cover 17, exhaust the airbag 10 through the air duct 16, and relieve the pressure on the radial artery. The second way is to rotate the rotating block 13 in the opposite direction, disengage the thread 12 from the threaded tube 8, and push the cover body 7 upward through the rebound force of the spring 14, thereby driving the rotating shaft 11 to move upward, so that the pressure plate 9 and the airbag 10 at the lower end of the rotating shaft 11 move upward, and relieve the pressure on the radial artery.
