[0056] The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0057] The present embodiment provides a femoral artery puncture post-hemostatic compression device, which comprises a compression device body and a compression device head. Figures 1-6As shown, it comprises: a compressor body 1, an upper cover 2, a movable assembly, a limiting structure, a lower pressing assembly and a fixing bandage; wherein the compressor body 1 has a mounting inner cavity 3, the top of the mounting inner cavity 3 is provided with an opening, and the bottom is provided with a first through hole 5; the upper cover 2 is fixedly covered and mounted on the top opening of the mounting inner cavity 3, and has a second through hole 7 opposite to the first through hole 5; the movable assembly is rotatably mounted inside the mounting inner cavity 3; the limiting structure is arranged between the upper cover 2 and the movable assembly, and is used for limiting the rotation of the movable assembly relative to the upper cover 2; the lower pressing assembly is mounted in cooperation with the movable assembly and can move up and down relative to the movable assembly to pressurize hemostasis; the fixing bandage is two, one end is fixedly connected with both ends of the compressor body 1, and the other end can be connected with each other, and is used for fixing the compressor body 1.

[0058] When the femoral artery puncture post-hemostasis compressor of the utility model is used, first, the lower pressing assembly is aligned with the puncture point, and the fixing bandage is used to fix the compressor body 1 on the thigh of the operation side; then the movable assembly and the upper cover 2 are fixed through the limiting structure; then the lower pressing assembly is rotated clockwise, the pressure of the bottom of the lower pressing assembly on the puncture point is gradually increased, and the compression hemostasis requirement is reached; finally, the limiting structure is released to limit the movable assembly, so that the lower pressing assembly can rotate and move relative to the compressor body 1. The femoral artery puncture post-hemostasis compressor of the embodiment allows doctors or nurses to accurately adjust the compression strength of the hemostat on the puncture point by rotating through the design of the knob type lower pressing, and the accurate pressure control helps to prevent tissue damage caused by excessive compression, while ensuring sufficient pressure to effectively stop bleeding; when the lower pressing assembly presses the hemostasis point, the bottom does not rotate, which will not cause secondary injury to the femoral artery puncture point; when the patient moves, the muscle movement causes the puncture point to rotate relative to the lower pressing assembly, which can drive the lower pressing assembly to rotate synchronously, and the relative rotation will not cause secondary injury to the puncture point.

[0059] As shown in Figure 2 and Figure 3 As shown, the end of the top opening of the mounting inner cavity 3 is uniformly provided with a plurality of first threaded holes 4; opposite to the first threaded holes 4, a plurality of first through holes 5 are uniformly arranged on the upper cover 2, and a first screw 8 is screwed with the first threaded holes 4 after passing through the first through holes 5, so that the upper cover 2 is fixedly covered and mounted on the top opening of the mounting inner cavity 3.

[0060] As preferred, the first through hole 5 is a countersunk hole.

[0061] As shown in Figure 3As shown, the movable assembly comprises a movable disc 9 rotatably mounted in the mounting inner cavity 3. The arrangement of the movable disc 9 can ensure that the relative position of the lower pressing piece 17 and the puncture point remains stable after pressurization, solving the problem that in the prior art, after the puncture point on the inner side of the thigh root is pressurized, even if the patient's lower limbs have small movements, the relative position between the pressurization point of the femoral artery pressor and the femoral artery puncture point is unstable, and even the head segment of the pressor is displaced, causing bleeding at the puncture point of the patient.

[0062] As shown in the figure, Figures 3-4 A plurality of mounting holes 12 are uniformly formed on the movable disc 9, and a plurality of balls 10 are movably mounted in the mounting holes 12. The movable disc 9 is in rotatable contact with the upper cover 2 through the balls 10. The design of the balls 10 changes the relative movement mode between the movable disc 9 and the upper cover 2 from sliding friction to rolling friction, and the resistance of rolling friction is much smaller than that of sliding friction. Therefore, the friction and wear of the movable disc 9 during rotation can be significantly reduced, and the movable disc 9 can rotate more smoothly without jamming or excessive resistance.

[0063] As a preferred embodiment, the mounting holes 12 are blind holes with openings facing the upper cover 2.

[0064] As shown in the figure, Figure 3 An internally threaded cylinder 11 is formed in the middle of the movable disc 9, which extends a certain length in the vertical direction and protrudes from the first through hole 5 and the second through hole 7.

[0065] As shown in the figure, Figure 3 The lower pressing assembly comprises a transmission screw rod 13 and a lower pressing piece 17. The transmission screw rod 13 is screw-mounted in the internally threaded cylinder 11, and a rotating handle 14 is arranged at the top end, and an axle head 15 is arranged at the lower end. The lower pressing piece 17 is rotatably connected with the axle head 15 for pressurizing hemostasis. The lower pressing piece 17 is designed as an elliptical curved surface structure, which is more consistent with the shape of the affected groin of the puncture point, is more fixed, can better release pressure at the puncture point, and effectively prevents blood from leaking out.

[0066] As shown in the figure, Figure 3 A micro deep groove ball bearing 16 is mounted on the axle head 15, and the outer ring of the micro deep groove ball bearing 16 is fixedly mounted on a bearing fixing seat 18 on the back of the lower pressing piece 17. The micro deep groove ball bearing 16 can prevent the lower pressing piece 17 from rotating with the transmission screw rod 13, solving the problem that the compression head at the lower end of the bolt rotates with the transmission screw rod 13, causing secondary injury to the femoral artery puncture point and bleeding.

[0067] As shown in the figure, Figure 5As shown, the limiting structure includes: a U-shaped clamping groove 20 and a boss 19; wherein the U-shaped clamping groove 20 is provided on the upper cover 2, the opening is towards the center position; the boss 19 is one, fixedly arranged on the outer wall of the inner threaded cylinder 11; the boss 19 can be pluggably installed in the U-shaped clamping groove 20. The design of the boss 19 is to form a matching relationship with the U-shaped clamping groove 20; when the height of the transmission screw rod 13 needs to be adjusted, the boss 19 is clamped into the U-shaped clamping groove 20, the relative positioning of the movable disc 9 and the upper cover 2 is realized; when the height adjustment of the transmission screw rod 13 is completed, the movable disc 9 needs to be freely rotated, the boss 19 is removed from the U-shaped clamping groove 20. This limiting structure not only ensures that the pressure adjustment can be smoothly realized, but also can be synchronized when the muscles below the lower pressing piece 17 move, thereby ensuring the stability of the pressure application.

[0068] In this embodiment, the two ends of the pressure applicator body 1 are respectively provided with a first connecting buckle 6; as Figure 2 and Figure 4 As shown, the fixed band includes: a right band 22 and a left band 21; wherein the right band 22 is fixed at one end on the right first connecting buckle 6 and extends outward at one end; the left band 21 is fixed at one end on the left first connecting buckle 6 and has a fastening device installed at the other end; the fastening device is used to detachably lock and connect the left band 21 and the right band 22. The fastening device detachably locks and connects the left band 21 and the right band 22, ensuring the stability of the pressure applicator on the patient. This stability is crucial for maintaining continuous compression force, which can effectively prevent the displacement of the pressure applicator caused by patient movement or external interference, thereby ensuring the hemostatic effect.

[0069] As shown in Figure 6 The fastening device includes: a fixed base 23, a movable buckle 24 and a fixed rivet 27; wherein the fixed base 23 is rectangular as a whole, has a square groove at the upper end, has openings at both sides of the middle part, and has a second connecting buckle 28 at the rear end; the second connecting buckle 28 is installed at the tail end of the left band 21; the movable buckle 24 is rectangular in structure as a whole, has an opening at the rear end, and has a fixed tooth 25 at the left lower end; the fixed rivet 27 is installed in the openings of the fixed base 23 and the movable buckle 24, so that the movable buckle 24 is rotatably installed in the square groove of the fixed base 23; the movable buckle 24 can rotate around the fixed rivet 27.

[0070] The use method of the hemostatic pressure device after femoral artery puncture in the embodiment is as follows: first, align the lower pressing assembly with the puncture point, ensure that the lower pressing sheet 17 at the bottom of the lower pressing assembly can be in close contact with the puncture point on the skin, and fix the pressure device main body 1 on the thigh of the operation side by using the fixing belt; ensure that the hemostatic pressure device will not be displaced or fall off; then fix the movable assembly with the upper cover 2 through the limiting structure; then rotate the rotating handle 14 clockwise to gradually increase the pressure of the lower pressing sheet 17 on the puncture point; when the lower pressing assembly presses the hemostatic point, the bottom will not rotate, and will not cause secondary injury to the femoral artery puncture point; when the patient moves, the muscle movement causes the puncture point to rotate relative to the lower pressing assembly, which can drive the lower pressing assembly to rotate synchronously, and will not cause relative rotation to cause secondary injury to the puncture point; during the rotation process, the reaction of the patient and the bleeding condition of the puncture site need to be closely observed; until the dorsalis pedis artery pulse can be felt and there is no bleeding at the puncture site, the rotation of the rotating handle 14 can be stopped. At this time, the hemostat has successfully compressed the femoral artery, and the purpose of hemostasis is achieved, then the limiting structure is released to limit the movable assembly, so that the lower pressing assembly can rotate and move relative to the pressure device main body 1 under the action of the movable assembly; after 8-10 hours of compression on the puncture point, if there is no bleeding or hematoma, the pressure of the lower pressing assembly on the puncture point can be gradually released; when releasing the pressure, the rotating handle 14 should be rotated counterclockwise slowly to avoid sudden release of pressure causing discomfort or recurrence of bleeding in the patient.

[0071] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the technical scheme.
