[0002] The radial artery hemostat is a medical device used for hemostasis, usually used for hemostasis after interventional surgery. Interventional surgery includes coronary artery intervention surgery, puncture and other surgeries, which usually require puncture in the surgical area for ease of operation.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1 and Figure 3 , Figure 1 This is a schematic diagram of the structure of the utility model. Figure 3 For this utility model Figure 1 A schematic diagram of the structure at A in the middle. A radial artery compression hemostat includes: a fixing assembly 1 including a fixing plate 11 and a fixing belt 12, wherein the fixing belt 12 is connected to the fixing plate 11 end to end, and the radial artery compression hemostat can be fixed on the arm by adjusting the length of the fixing belt 12; an adjusting assembly 2 including an adjusting member 21 and a follower 22, wherein the adjusting member 21 is arranged on one side of the fixing plate 11, and the follower 22 is arranged on the other side of the fixing plate 11, and the follower 22 passes through the fixing plate 11 and extends into the adjusting member 21, and the follower 22 can be adjusted by the adjusting member 21 so that the follower 22 gradually moves away from the adjusting member 21; a hemostatic assembly 3 is provided The follower 22 is placed at one end away from the adjusting member 21, and compresses the puncture site to stop bleeding. After the follower 22 moves away from the adjusting member 21 under the action of the adjusting member 21, it drives the hemostatic component 3 to move synchronously, moves toward the puncture site to be compressed, and compresses the puncture site to stop bleeding; and the detection component 4 is arranged at one end of the follower 22 close to the hemostatic component 3, and the detection component 4 is in contact with the arm to detect the blood oxygen saturation of the arm, and automatically triggers an audible and visual alarm prompt when the blood oxygen saturation exceeds the set range, reminding medical staff to adjust the compression pressure of the hemostat in time to avoid excessive or too loose compression causing discomfort or injury to the patient.

[0029] Specifically, the detection component 4 includes a detection piece 41 and an elastic piece 42. The detection piece 41 is arranged at one end of the follower 22 close to the hemostasis component 3, and the elastic piece 42 is arranged between the follower 22 and the detection piece 41. The elastic piece 42 applies elastic force to the detection piece 41 toward the arm, so that after the radial artery compression hemostat is fixed on the arm and the puncture site is compressed to stop bleeding, regardless of whether the hemostasis component 3 is tightly fitted to the puncture site, the detection piece 41 can be in close contact with the arm and detect the blood oxygen saturation, thereby ensuring the detection accuracy of the detection piece 41.

[0030] Specifically, the detection element 41 is a photoelectric sensor, which performs optical measurement based on the principle that the amount of light absorbed by arterial blood changes with the pulse, and converts the detected red light and infrared light passing through the arterial blood vessels into electrical signals to obtain a set of data. Based on this data, the background algorithm is used to calculate the estimated value of the user's blood oxygen saturation, thereby enabling real-time detection of the patient's blood oxygen saturation.

[0031] Specifically, the detection piece 41 is annular and is arranged around the hemostasis component 3, so that the detection piece 41 is separated from the hemostasis component 3, thereby reducing the occurrence of the situation where the detection effect of the detection piece 41 is affected by the use of thicker hemostatic gauze, and replacing the hemostatic gauze will not affect the detection piece 41, thereby improving the recycling ability of the radial artery compression hemostat.

[0032] Reference Figure 2 , Figure 2 The schematic diagram of the structure of the regulating assembly of the present invention is shown in FIG. The regulating assembly 2 further includes a pressure regulating member 23, a coil 24 and a pressure applying member 25. The inner cavity of the driven member 22 is provided with a cavity 221, and the cavity 221 is connected to the outside of the driven member 22 away from the regulating member 21. The pressure regulating member 23 is provided at the end of the cavity 221 close to the regulating member 21. The coil 24 is located on the side wall of the driven member 22 and is arranged around the pressure regulating member 23, so that the pressure regulating member 23 is in the shape of an energized solenoid. When the pressure regulating member 23 is energized, the coil 24 is turned on. 4 is magnetized, thereby enhancing the magnetic field strength generated by the pressure regulating member 23. The pressure member 25 is arranged at one end of the cavity 221 away from the regulating member 21 and extends out of the cavity 221. The other end of the pressure member 25 is connected to the hemostasis component 3. The pressure member 25 is made of magnetic material, so that after controlling the current intensity in the pressure regulating member 23, the repulsive force on the pressure member 25 can be enhanced or weakened, thereby controlling the pressure force on the puncture site, thereby achieving a precise control effect.

[0033] Furthermore, when the radial artery compression hemostat is initially used to stop bleeding at the puncture site, the magnetic repulsion of the pressure regulating member 23 on the pressure member 25 is relatively uniform, so that one end of the pressure member 25 is located in the lower middle part of the cavity 221. Therefore, after the compression of the puncture site is completed, the current intensity can be further increased or weakened to adjust the compression force.

[0034] Specifically, the voltage regulating member 23 is an iron core, so as to maximize the ability to enhance the magnetic field.

[0035] Specifically, the detection element 41 and the coil 24 are electrically connected, so that after the blood oxygen saturation is detected by the detection element 41, when the blood oxygen saturation exceeds the set range, an audible and visual alarm can be issued, and the current intensity of the coil 24 can be automatically controlled, thereby automatically adjusting the compression force.

[0036] Specifically, the hemostatic component 3 includes a hemostatic component 31 and an adhesive component 32. The hemostatic component 31 is arranged at the end of the pressure-applying component 25 away from the pressure-regulating component 23, and the adhesive component 32 is arranged between the pressure-applying component 25 and the hemostatic component 31. The hemostatic component 31 is a disposable hemostatic material, and the adhesive component 32 can stick the hemostatic component 31 well, so that it can be recycled to stop bleeding for multiple patients, thereby improving its service life.

[0037] Specifically, the adjusting member 21 and the driven member 22 are detachably connected via threads, so that the driven member 22 can be adjusted by rotating the adjusting member 21 to move away from or close to the puncture site to be hemostatic.

[0038] Working Principle: After the hemostat is placed on the site to be hemostatically controlled via the fixing assembly 1, the coil 24 is energized, causing the end of the pressure-applying member 25 close to the pressure-regulating member 23 to move to a position near the middle and lower portion of the cavity 221. The adjusting member 21 is then rotated, so that the follower 22, under the action of the thread, can drive the pressure-applying member 25 toward the puncture site, and drive the hemostatic member 31 and the detection member 41 to move synchronously, so that the hemostatic member 31 and the detection member 41 are in contact with the puncture site and compress the puncture site to stop bleeding. At the same time, the detection member 41 monitors the blood oxygen saturation of the arm in real time.

[0039] When the detection element 41 detects that the blood oxygen saturation exceeds the set range, it issues an audible and visual alarm and automatically controls the current intensity in the coil 24 at the same time, so that the pressure of the pressure member 25 on the puncture site increases or decreases.

[0040] To summarize, the radial artery compression hemostat, by providing a detection component 4 that is in close contact with the arm, enables the detection component 4 to monitor the patient's blood oxygen saturation when the radial artery compression hemostat is used to stop bleeding at the puncture site. When the blood oxygen saturation exceeds the set range, the detection component 4 can automatically trigger an audible and visual alarm prompt to remind medical staff to adjust the compression pressure of the hemostat in time to avoid excessive or loose compression causing discomfort or injury to the patient.
