[0034] As Figure 1-10 shown, a compression device for a hemostatic ball of the present invention includes a fixing block 1 covering the puncture point on the radial artery of the wrist. Fixing straps 2 for fixing on the wrist are arranged on both side edges of the fixing block 1, and further include:

[0035] A hemostasis assembly 3, including an upper top cover 31 and a lower joint block 32 arranged in the inner cavity of the fixing block 1 with an upper and lower reserved moving gap, and several evenly distributed hemostatic balls 33 arranged in the moving gap between the upper top cover 31 and the lower joint block 32 for hemostasis of the puncture point;

[0036] An operating mechanism 4, arranged on the fixing block 1, for performing a tightening operation on the hemostasis assembly 3 and the fixing strap 2 at the puncture point. With such a design, through the hemostasis assembly 3 designed on the fixing block 1 and the operating mechanism 4 for synchronously operating the fixing strap 2 and the hemostasis assembly 3 to compress and stop bleeding at the puncture point of the radial artery position of the wrist, the tightening of the fixing strap 2 and the downward pressure of the hemostasis assembly 3 can be synchronized, achieving the effect of positioning the puncture point and fixing the present device, and can perform compression hemostasis according to the specific situation of the patient, without repeatedly operating the fixing strap 2, reducing the influence on the puncture point such as external force extrusion during repeated fixing operations.

[0037] It should be noted that two soft ropes are symmetrically adhesively connected between the upper top cover 31 and the lower joint block 32, which play a role in restraining and fixing the upper top cover 31 and the lower joint block 32.

[0038] It should be noted that the structure of the hemostatic ball 33 is that an elastic support body is externally coated with a layer of hemostatic cotton layer, and hemostatic notoginseng powder for hemostasis is filled between the hemostatic cotton layer and outside the elastic support body. With such a design, through the elastic support body, it is avoided that the hemostatic ball 33 shrinks significantly after absorbing blood, affecting the coverage of the puncture point, and through the hemostatic cotton layer and the filled hemostatic notoginseng powder, a rapid hemostasis effect is achieved.

[0039] In one embodiment, a section of opening is provided on the fixing belt 2 corresponding to the position of the fixing block 1. Two winding belts 21 are correspondingly provided on both sides of the opening and at the break point of the fixing belt 2. With such a design, by sewing and fixing two winding belts 21 on the edges of the cut opening on the fixing belt 2, the length of the winding belt 21 can be changed to adjust the length of the fixing belt 2, so as to achieve the fixing and tightening effect of the present device on different wrists.

[0040] In one embodiment, the hemostasis component 3 further includes several through holes evenly distributed on the end face of the lower combining block 32 corresponding to the number of hemostasis balls 33. A pressing piece 34 for squeezing and outputting the hemostasis balls 33 is fixedly embedded in the through holes. With such a design, the pressing piece 34 embedded in the through holes machined and opened on the end face of the lower combining block 32 can not only seal the outlet of the hemostasis balls 33, but also squeeze and output the hemostasis balls 33 through the pressing piece 34.

[0041] It should be noted that as Figure 10 shown, the pressing piece 34 is composed of multiple semi-circular silicone pads symmetrically arranged along the center and surrounding a circle, and a gap is left between adjacent two semi-circular silicone pads. When the hemostasis balls 33 are subjected to an external force, the gap on the pressing piece 34 facilitates the squeezing and output of the hemostasis balls 33 and contacts the puncture point position of the radial artery of the wrist for hemostasis.

[0042] In one embodiment, three pin posts 35 with equal perimeter distribution are provided on the circumferential surface of the lower combining block 32. Two semi-ring adhesive patches 36 for fixing the hemostasis component 3 at the puncture point are symmetrically provided on the top of the upper top cover 31. A release film is provided outside the semi-ring adhesive patches 36. With such a design, through the three pin posts 35 integrally formed on the circumferential surface of the lower combining block 32 with equal perimeter, the installation of the lower combining block 32 and related structures on the lower combining block 32 can be carried out in the inner cavity of the fixing block 1; also, through the two symmetric semi-ring adhesive patches 36 integrally formed on the top of the upper top cover 31 and the release film pasted outside the semi-ring adhesive patches 36, after separating and removing the hemostasis component 3, the hemostasis component 3 can be fixed on the puncture point on the radial artery of the wrist through the adhesive surface of the semi-ring adhesive patches 36, and pressed and left at the puncture opening to prevent skin puncture point infection.

[0043] Preferably, the lower combining block 32 adopts a combination of a bottom box and a rotating movable ring, and the pin posts 35 are integrally formed on the outer circumferential surface of the movable ring of the lower combining block 32, and the three pin posts 35 are equally distributed on the outer circumferential surface of the movable ring included on the lower combining block 32.

[0044] It should be noted that the base materials of the upper top cover 31, the lower combining block 32, the pin posts 35 and the semi-ring adhesive patches 36 are all made of soft silicone material.

[0045] In one embodiment, the operating mechanism 4 includes a guide block 41 provided on the top of the fixed block 1, and support blocks 42 symmetrically arranged on the left and right sides of the guide block 41. A pressing rod 411 passing through the top surface of the fixed block 1 and contacting the end surface of the upper top cover 31 is centrally provided on the guide block 41. A winding unit 43 for adjusting the tightness of the fixing belt 2, a power lead screw 44 having a motor 441 for driving the guide block 41 to move vertically, and a transmission unit 45 for cooperative operation are provided on the support block 42. With such a design, through the support blocks 42 integrally formed symmetrically on the left and right sides of the top of the fixed block 1, and the guide block 41 connected by the power lead screw 44 in the inner cavities of the two support blocks 42, when the motor 441 connected to the coupling on the power lead screw 44 is started, the driving force generated by the double lead screw drive structure can drive the guide block 41 combined between the two support blocks 42 to move in the vertical direction, so that the hemostasis assembly 3 facing the puncture opening generates a downward pressing force; also, through the pressing rod 411 rotatably connected to the center of the guide block 41, the pressing rod 411 can move downward in a rotating manner and abut against the hemostasis assembly 3, further pushing the downward pressing force generated by the hemostasis assembly 3 to perform a compression hemostasis operation on the puncture point at the position of the radial artery of the wrist.

[0046] It should be noted that the screw holes on the support plates integrally formed on both sides of the guide block 41 are in rotational mating connection with the external threads of the power lead screw 44.

[0047] In one embodiment, the winding unit 43 includes a winding shaft 431 provided at the end of the upper end of the winding belt 21. A worm gear 432 is provided in the middle section of the winding shaft 431, and a worm 433 is engaged with the side of the worm gear 432. With such a design, through the worm gear 432 sleeved and fixed in the middle section of the winding shaft 431 and the worm 433 engaged with the side of the worm gear 432, the winding shaft 431 will generate a rotational movement under the meshing transmission of the worm 433 and the worm gear 432, and can wind or stretch the winding belt 21 fixed on the winding shaft 431, playing a role in adjusting the length of the fixing belt 2 and realizing the fixing function of the present device at the position of the radial artery of the wrist.

[0048] In one embodiment, the transmission unit 45 includes a first pulley 451 disposed at the upper end of the power lead screw 44 and a second pulley 452 disposed at the upper end of the worm 433. A transmission belt 453 for driving force transmission is horizontally disposed between the first pulley 451 and the second pulley 452. With this design, by sleeving and fixing the first pulley 451 and the second pulley 452 at the upper ends of the power lead screw 44 and the worm 433 on the same horizontal plane, and by winding the same transmission belt 453 around the first pulley 451 and the second pulley 451, when the power generated by the power lead screw 44 is transmitted to the second pulley 452 through the first pulley 451 and the transmission belt 453, a synergistic effect between the power lead screw 44 and the winding unit 43 can be generated. As long as the bottom surface of the lower block 32 of the hemostasis assembly 3 is aligned with the puncture opening, under the power transmission of the transmission unit 45, the hemostasis assembly 3 can be operated to press down while the fixing band 2 is tightened, achieving the effect of positioning the puncture opening and fixing the present device.

[0049] In one embodiment, an integrally formed mounting ring 5 and a bottom plate 6 are vertically arranged inside the cavity of the fixing block 1 and outside the hemostasis assembly 3. An elastic column 51 that is in extrusion contact with the upper top cover 31 is arranged inside the mounting ring 5. A strip-shaped ring 52 for separating the release film outside the semi-ring adhesive sheet 36 is arranged at the inner edge of the mounting ring 5. An L-shaped limiting groove 53 corresponding to the pin 35 is arranged on the side of the mounting ring 5. A notch 61 that can pass through up and down is arranged on the side of the bottom plate 6 near the lower block 32 and corresponding to the pin 35. With this design, through the mounting ring 5 designed outside the hemostasis assembly 3 in the cavity of the fixing block 1 and the bottom plate 6 integrally formed on the lower surface of the mounting ring 5, and two elastic columns 51 symmetrically fixed by screws inside the cavity of the mounting ring 5, an elastic supporting force is provided. When the hemostasis assembly 3 is fixedly combined on the bottom surface of the bottom plate 6, the elastic columns 51 will be elastically extruded. Once there is no external force restraint, the hemostasis assembly 3 in the lower part of the cavity of the mounting ring 5 will be automatically separated. And through the strip-shaped ring 52 fixed by screws at the inner edge of the mounting ring 5, after the hemostasis assembly 3 is fixedly combined, one end of the release film outside the semi-ring adhesive sheet 36 can be pre-pasted with the strip-shaped ring 52. Under the elastic acting force of the elastic column 51, the release film outside the semi-ring adhesive sheet 36 can be separated synchronously. The release film outside the semi-ring adhesive sheet 36 can be torn off while the hemostasis assembly 3 is separated, and the skin puncture point can be pasted and fixed through the adhesive surface on the semi-ring adhesive sheet 36, achieving the effect of retaining the hemostasis assembly 3. Also, through the L-shaped limiting groove 53 machined on the side of the mounting ring 5, after the pin 35 is docked and combined, the pin 35 can be rotated, so that the hemostasis assembly 3 is combined and placed inside the mounting ring 5. And by separating the pin 35 in the L-shaped limiting groove 53 on the side of the mounting ring 5 in a way of rotating first and then moving down, the hemostasis assembly 3 can be removed and taken out, and the convenient replacement effect of the hemostasis assembly 3 can also be achieved.

[0050] It should be noted that the installation ring 5 and related structures on the installation ring 5 are all made of silica gel material.

[0051] In one embodiment, an airbag 7 is adhesively bonded to the inner surface of the fixing band 2, and an exhaust valve 71 and a balloon 72 for manual inflation and deflation are provided at one end of the airbag 7. With this design, after the present device is fixed at the puncture point of the radial artery of the wrist to be hemostatic through the airbag 7 adhesively bonded to the inner surface of the fixing band 2, the exhaust valve 71 or the balloon 72 on the airbag 7 can be selected to perform exhaust or inflation operations. The gap left after opening the exhaust valve 71 for exhaust can, on the one hand, take out the puncture catheter for subsequent hemostasis operations, and on the other hand, the pressure is relaxed to observe whether there is bleeding after 2-3 minutes of compression hemostasis. By squeezing the balloon 72 connected to the airbag 7, the compression force can be finely adjusted in cooperation with the tightening length adjustment of the fixing band 2, and the missing compression pressure can also be compensated.

[0052] It should be noted that the fixing band 2 is made of silica gel material.

[0053] In one embodiment, a lid 8 that can be opened and closed is hinged to the side of the fixing block 1. With this design, through the lid 8 hinged to one end of the side of the fixing block 1, the hemostasis component 3 can be disassembled and removed in a way of rotating and moving downward within the reserved operation space by the flipping and opening / closing manner of the lid 8, and the convex surfaces of the lower joint block 32 and the extruded hemostatic ball 33 on the hemostasis component 3 are used to protect the puncture point after hemostasis from infection.
