Technical Field

[0001] The utility model relates to the technical field of radial artery hemostasis, in particular to a radial artery compression hemostasis device. Background Art

[0002] The radial artery is located shallowly between the lower end of the radius and the radial flexor carpi tendon, making it an ideal location for pulse palpation and puncture. As radial artery puncture technology becomes more and more widely used, postoperative hemostasis of the radial artery puncture site is increasingly valued. Interventional treatment via the radial artery is becoming more and more popular. After interventional surgery, hemostasis technology for radial artery puncture sites has developed in recent years. In the early stage, manual finger pressure and bandage were mostly used. This method is an empirical hemostasis method and varies from person to person, resulting in poor hemostasis effect.

[0003] Most of the existing radial artery compression hemostasis devices only use an inflatable air bag to compress the puncture point to stop bleeding. Compression hemostasis can only be performed by adjusting the pressure of the air bag, and it cannot be adjusted accurately. Too much pressure can easily cause poor blood flow and finger numbness. Too little pressure can easily cause bleeding and poor hemostasis effect. Therefore, the present application provides a radial artery compression hemostasis device, which uses two methods to coordinate radial artery compression hemostasis to solve the above-mentioned technical problems. Utility Model Content

[0004] The utility model aims to provide a radial artery compression hemostasis device with a simple structure. By adjusting the pressure of the outer tube and the air bag, radial artery compression hemostasis can be achieved in two ways.

[0006] Furthermore, the outer cylinder is rotatably arranged with the base, a protrusion is arranged at the bottom of the outer cylinder, a groove is arranged inside the base, the protrusion is matched with the groove, and a ball is arranged at the bottom of the protrusion to facilitate the rotation of the outer cylinder.

[0007] Furthermore, the outer cylinder and the inner cylinder are rotatably arranged, the inner surface of the outer cylinder is provided with an internal thread, the outer surface of the inner cylinder is provided with an external thread, the internal thread is adapted to the external thread, and a limiting hole for limiting is provided on the side of the inner cylinder.

[0008] Furthermore, an inflation hole is provided on the side of the inflatable airbag, the inflation hole is connected to an inflation tube, a gas switch is provided on the inflation tube, and the inflatable airbag is composed of a plurality of small square airbags, and two adjacent small airbags are interconnected.

[0010] Furthermore, a locking block is provided on the bottom surface of the support plate, and the locking block is arranged opposite to the protective pad.

[0011] Therefore, the utility model adopts a radial artery compression hemostasis device with the above structure, which has a simple structure and realizes radial artery compression hemostasis in two ways by adjusting the pressure of the outer tube and the air bag.

[0022] Example

[0023] like Figure 1 and Figure 2 As shown, a radial artery compression hemostasis device includes a support plate 2, and bandages 1 are provided at both ends of the support plate 2. A protective pad 8 for protection is provided on the inner surface of the bandage 1. An outer tube 4 is provided above the support plate 2, and an inner tube 3 is rotatably provided inside the outer tube 4. A base 5 is provided at the bottom of the outer tube 4, and the base 5 is provided on the upper surface of the support plate 2. The bottom of the inner tube 3 passes through the support plate 2, and an inflatable airbag 6 is provided at the bottom end. The inflatable airbag 6 is rotatably provided with the inner tube 3 according to the existing structure. A timer 9 is provided on one side of the base 5, and the timer 9 is connected to the support plate 2 through a bracket 10.

[0024] like Figure 1 As shown, the bottom surface of the support plate 2 is provided with a clamping block 11, and the clamping block 11 is arranged opposite to the protective pad 8. When in use, the clamping block 11 is clamped on one side of the back of the hand, which can effectively prevent the entire device from moving and ensure the effect of hemostasis.

[0025] like Figure 3 As shown, the outer cylinder 4 and the base 5 are rotatably arranged, a protrusion is arranged at the bottom of the outer cylinder 4, a groove is arranged inside the base 5, the protrusion is adapted to the groove, and a ball 17 is arranged at the bottom of the protrusion to facilitate the rotation of the outer cylinder 4. The ball 17 can reduce the friction between the outer cylinder 4 and the base 5, making the outer cylinder 4 easier to rotate.

[0026] The outer cylinder 4 and the inner cylinder 3 are rotatably arranged, the inner surface of the outer cylinder 4 is provided with an internal thread, the outer surface of the inner cylinder 3 is provided with an external thread, the internal thread is adapted to the external thread, and the side of the inner cylinder 3 is provided with a limiting hole 15 for limiting. When the outer cylinder 4 is rotated, the inner cylinder 3 can move up and down under the cooperation of the internal thread and the external thread, thereby driving the inflatable airbag 6 to move up and down. After rotating to a suitable position, the inner cylinder 3 and the outer cylinder 4 are limited by the limiting hole 15 to prevent them from rotating.

[0027] like Figure 2 and Figure 3 As shown, the interior of the inner tube 3 is provided with a hollow observation window 12, and a magnifying glass 16 is provided inside the observation window 12. Through the observation window 12 and the magnifying glass 16, the hemostasis of the radial artery can be observed at any time, so as to facilitate adjustment at any time.

[0028] like Figure 2 and Figure 5 As shown, the side of the inflatable airbag 6 is provided with an inflating hole 7, which is connected to an inflating tube 13, and a gas switch 14 is provided on the inflatable airbag 13. The inflatable airbag 6 is composed of a plurality of small square airbags 18, and two adjacent small airbags 18 are connected to each other. The inflatable airbag 6 can be inflated through the inflating tube 13, and the gas switch 14 is turned off after the restart is completed. Compared with the existing whole compression airbag, the inflatable airbag 6 composed of a plurality of small airbags 18 can avoid the problems of poor blood flow and finger numbness caused by long-term compression.

[0029] When in use, the whole device is put on by the strap 1, and the inflatable airbag 6 is filled with a certain amount of gas. The inflatable airbag 6 is located just above the bleeding point, and the inner tube 3 is lowered by rotating the outer tube 4, so that the inflatable airbag 6 is lowered and pressed on the bleeding point, and then the pressure inside the inflatable airbag 6 is further adjusted, or the height of the inner tube 3 is further adjusted, and the bleeding situation of the bleeding point is observed through the observation window 12, so that the bleeding point does not bleed and the pressure is appropriate, and then the inner tube 3 is fixed through the limit hole 15. During the compression hemostasis process, the hemostasis situation can be observed at any time through the observation window 12, and then the pressure is adjusted by adjusting the height of the inner tube 3, and the timer 9 is used to count the time of compression hemostasis.

[0030] Therefore, the utility model adopts a radial artery compression hemostasis device with the above structure, which has a simple structure and realizes radial artery compression hemostasis in two ways by adjusting the pressure of the outer tube and the air bag. Compared with the existing hemostasis device, it is more convenient to adjust and has a better hemostasis effect.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
