Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a compression hemostasis device for cardiac intervention surgery. Background Art

[0002] In cardiac interventional surgery, compression hemostasis devices are mainly used to stop bleeding at the puncture point. For example, in radial artery puncture surgery, the classic radial artery approach and the distal radial artery approach are two common transradial artery interventional surgical routes. The classic radial artery approach: the puncture point is located at the proximal radial artery in the forearm, usually 1-2 cm above the radial styloid process; the distal radial artery approach: the puncture point is located at the distal radial artery, that is, the anatomical snuff box area (located in the depression at the base of the thumb), which is the distal branch of the radial artery.

[0003] The recommended compression hemostasis time for the classic radial artery approach is generally 6 hours, and the compression time for the distal radial artery approach is generally 2-3 hours. The patient is usually required to brake the wrist after the operation. The existing radial artery compression hemostasis equipment can only compress and stop bleeding, but cannot assist in wrist braking. In addition, the anatomical morphology at the distal radial artery puncture point is irregular, the size of human hands varies greatly from person to person, and the compression hemostasis device is difficult to fix. Therefore, based on the above problems, the present invention provides a compression hemostasis device for cardiac interventional surgery to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a compression hemostasis device for cardiac interventional surgery by setting an adjustment component. The adjustment component can not only extend the width of the compression device to facilitate the support and fixation of the wrist, thereby achieving the effect of wrist braking, but also the adjustment component can change the position and angle of the adjustment plate to better adapt to the hand characteristics of different people, thereby making it more convenient to fix the compression hemostasis device and improving the fixation efficiency of the compression hemostasis device at the puncture point. The above setting can solve the problem that the existing radial artery compression hemostasis device cannot assist in wrist braking and the compression hemostasis device at the distal radial artery puncture point is difficult to fix.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A compression hemostasis device for cardiac interventional surgery includes a compression plate, a first hollow groove is slidably connected to the center of the compression plate, a bolt is internally threadedly connected to the first hollow groove, a compression pad is fixedly connected to the bottom of the bolt, and an adjustment component is used to assist the compression device in being fixed to the body, the adjustment component is connected to the bolt.

[0007] Optionally, the adjustment assembly includes an adjustment plate slidably connected to the bottom of the outer wall of the bolt, a sliding groove is penetrated through the adjustment plate, second hollow grooves are symmetrically opened on both sides of the adjustment plate, one side of the adjustment plate is penetrated through with evenly distributed lightweight grooves, and the adjustment plate is provided with a flange portion at the edge near the lightweight groove.

[0008] Optionally, both sides of the adjustment plate corresponding to the second hollow groove have a downward curvature, and the length of the adjustment plate is smaller than the length of the pressure plate.

[0009] Optionally, the sliding groove is an L-shaped structure, and arc grooves are evenly distributed on the inner wall of the sliding groove. The spacing dimensions between the relative arc grooves are adapted to the outer wall dimensions of the bolt. A position spring plate is fixedly connected at the intersection of two adjacent arc grooves, and an angle spring plate distributed oppositely is fixedly connected at the center of the arc groove.

[0010] Optionally, two adjacent position spring sheets do not contact each other, and a first gap is formed between the position spring sheet and the inner wall of the sliding groove; two adjacent angle spring sheets do not contact each other, and a second gap is formed between one side of the angle spring sheet and the inner wall of the sliding groove; and a third gap is formed between the other side of the angle spring sheet and the inner wall of the sliding groove.

[0011] Optionally, oppositely distributed angle spring pieces are fixedly connected at the centers of both ends of the inner wall of the sliding groove, and the angle spring pieces and the third gap are both elastic curved surface structures.

[0012] Optionally, short fixing straps are sleeved on both sides of the adjustment plate through the second hollow groove, wherein the free end of one of the short fixing straps is fixedly connected to the second Velcro, and the free end of the other short fixing strap is fixedly connected to the third Velcro.

[0013] Optionally, the middle thickness of the pressing plate is greater than the thickness of the two sides of the pressing plate, the bottom of the pressing plate is provided with arc edges, and the two sides of the pressing plate are symmetrically provided with first hollow grooves, one of the first hollow grooves is sleeved with a long fixing belt, and the free end of the long fixing belt is fixedly connected with a first Velcro.

[0014] Optionally, the bottom of the bolt is fixedly connected to a position close to the compression pad with circular protrusions distributed in a circumferential array, and the outer wall size of the circular protrusion is larger than the size of the arc space formed between adjacent angle spring pieces.

[0015] Optionally, the length dimension of the circular protrusion is greater than the thickness dimension of the adjustment plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting an adjustment component, the adjustment component is set at the bottom of the pressure plate. The adjustment component can not only extend the width of the compression device to facilitate the support and fixation of the wrist, thereby achieving the effect of wrist braking, but also the adjustment component can be used to change the position and angle of the adjustment plate to better adapt to the hand characteristics of different people, thereby making it more convenient to fix the compression hemostasis device; the adjustment component can not only assist in wrist braking when compressing and stopping bleeding at the puncture point of the classic radial artery approach, but also can fix the distal radial artery puncture point that is difficult to fix, better adapt to the situation where the size of the human hand is large and the individual differences are large, and improve the fixation efficiency of the puncture point compression hemostasis device.

[0018] By setting sliding grooves and lightweight grooves, and utilizing the structural coordination between the sliding grooves and the bolts, the adjustment plate can be stretched outward, extending the width of the compression device, facilitating the support and fixation of the patient's wrist, and improving the efficiency of postoperative recovery. Evenly distributed lightweight grooves are opened throughout the adjustment plate to reduce material costs and structural deadweight while meeting structural strength requirements, effectively improving the practicability and economy of the equipment. Moreover, due to the setting of the lightweight grooves, the roughness of the contact surface between the adjustment plate and the skin is increased, thereby increasing friction, effectively preventing shaking, and ensuring the effect of compression and hemostasis.

[0019] By setting the position spring piece and the first gap, not only the sliding and fixing of the adjustment plate in the direction parallel to and perpendicular to the long axis of the pressure plate are achieved, and the relative position relationship between the adjustment plate and the pressure plate can be adjusted in multiple gears, but also the position spring piece and the adjustment plate are integrated and grooves are directly cut on the adjustment plate. Not only is the structure simple and ingenious, but the actual operation is convenient and labor-saving. In addition, the length of the circular protrusion is greater than the thickness of the adjustment plate, which does not affect the adjustment under different compression pressures. The circular protrusion and the bolt are an integrated manufacturing structure. Such a setting makes the processing technology of the two simpler during the production process, easier to produce and manufacture, reduces the manufacturer's capital investment, and does not affect the connection strength between the two, thereby improving the practicability of the compression equipment.

[0020] By setting circular protrusions and angle spring pieces, the angle spring pieces distributed in opposite directions are adapted to the outer contour size of the circular protrusions, and the circular protrusions set in an even number cooperate with the angle spring pieces fixedly connected on both sides of the inner wall of the sliding groove, so that the angle can be rotated for fine adjustment under multiple gear adjustments of the adjustment plate, which can better adapt to the situation where the size of human hands varies greatly from person to person. Moreover, the short fixing belt can be used alone for fixation, and then cooperate with the long fixing belt to achieve fixation in multiple places and directions, ensuring that the compression position does not shift, and can effectively compress the bleeding point, thereby improving the hemostasis effect.

[0038] like Figures 1 to 8As shown, an embodiment of the present invention provides a cardiac interventional surgery compression hemostasis device, including a pressure plate 1, a first hollow groove 2 is slidably connected at the center of the pressure plate 1, a bolt 5 is connected to the internal thread of the first hollow groove 2, and a compression pad 22 is fixedly connected to the bottom of the bolt 5; an adjustment component, the adjustment component is used to assist the compression device in being fixed on the body, the adjustment component is connected to the bolt 5, the cardiac interventional surgery compression hemostasis device provided by the present application is suitable for compression hemostasis after cardiac interventional surgery with classic radial artery access and distal radial artery access. When in use, the center of the compression pad 22 is aligned with the puncture point, the compression force is adjusted by the nut, and uniform pressure is applied to the puncture point by the compression pad 22 to reduce blood flow and promote blood coagulation. The specific structure of adjusting the compression force by the nut in the present device and its working principle are disclosed as prior art and therefore will not be elaborated on.

[0039] By setting an adjustment component, the adjustment component is set at the bottom of the pressure plate 1. The adjustment component can not only extend the width of the compression device to facilitate the support and fixation of the wrist, thereby achieving the effect of wrist braking, but also the position and angle of the adjustment plate 7 can be changed by the adjustment component to better adapt to the hand characteristics of different people, thereby making it more convenient to fix the compression hemostasis device; the adjustment component can not only compress and stop the hemostasis of the puncture point of the classic radial artery approach, but also fix the distal radial artery puncture point that is difficult to fix, better adapt to the situation where the size of the human hand is large and the individual differences are large, and improve the fixation efficiency of the puncture point compression hemostasis device.

[0040] As an implementation method in this embodiment, Figures 1 to 6 As shown, the adjustment component includes an adjustment plate 7 slidably connected to the bottom of the outer wall of the bolt 5, a sliding groove 10 is opened through the adjustment plate 7, second hollow grooves 8 are symmetrically opened on both sides of the adjustment plate 7, and evenly distributed lightweight grooves 9 are opened through one side of the adjustment plate 7. A flange portion 16 is provided at the edge of the adjustment plate 7 near the lightweight groove 9, and the adjustment plate 7 has a downward curvature on both sides corresponding to the second hollow groove 8. The length dimension of the adjustment plate 7 is smaller than the length dimension of the pressing plate 1, and short fixing straps 19 are sleeved on both sides of the adjustment plate 7 through the second hollow groove 8, and the free end of one short fixing strap 19 is fixedly connected to the second Velcro 20, and the free end of the other short fixing strap 19 is fixedly connected to the third Velcro 21. The middle thickness of the pressing plate 1 is greater than the thickness of the two sides of the pressing plate 1, and arc edges 3 are provided around the bottom of the pressing plate 1. First hollow grooves 2 are symmetrically opened on both sides of the pressing plate 1, and a long fixing strap 17 is sleeved on one of the first hollow grooves 2, and the free end of the long fixing strap 17 is fixedly connected to the first Velcro 18.

[0041] Specifically, the pressing plate 1 and the adjusting plate 7 are both rectangular structures with downward bending arcs on both sides. The length of the adjusting plate 7 is smaller than the length of the pressing plate 1. A first hollow groove 2 is penetrated on both sides of the pressing plate 1, and is connected to the long fixing belt 17 through the first hollow groove 2. A second hollow groove 8 is penetrated on both sides of the adjusting plate 7, and is connected to the short fixing belt 19 through the second hollow groove 8. A circular groove is opened at the center of the pressing plate 1, and a spiral handle 4 is provided on the circular groove. A bolt 5 is threadedly connected at the inner center of the spiral handle 4, and a compression pad 22 is fixedly connected to the bottom of the bolt 5. The compression pad 22 includes two layers. The upper layer is a structure of the same material as the bolt 5, and the lower layer is a medical silicone gasket for directly contacting the skin at the puncture point. The spiral design structure and the structure and working principle of the solid compression pad 22 here are all disclosed in the prior art and will not be described in detail here. The pressing plate 1, the spiral handle 4 and the adjusting plate 7 are provided with a plurality of screw threads. The plates 7 are all made of polycarbonate (PC) material, which has good mechanical strength and transparency, and is convenient for observing the compression site. Before use, confirm the position of the puncture point, align the compression pad 22 with the puncture point, ensure that the bottom of the compression pad 22 is closely attached to the skin, judge the distance between the patient's wrist and the puncture point, stretch the adjustment plate 7 in the direction close to the wrist, and then use the long fixing strap 17 and the short fixing strap 19 to fix the device to the patient's hand. Since the free ends of the short fixing strap 19 are provided with Velcro, the second Velcro 20 has only a burr surface at the bottom, and the top and bottom of the third Velcro 21 are both burr surfaces. When fixing, first fit the top of the second Velcro 20 to the skin, and then connect the third Velcro 21 to the short fixing strap 19, and use the burrs at the bottom of the third Velcro 21 and the long fixing strap 17 for secondary fixation, which is convenient for the stability of the entire fixing strap. The adjustment plate 7 is penetrated with evenly distributed lightweight grooves 9 (such as Figure 3 to Figure 4 and Figure 7 As shown in the figure, it can not only reduce the dead weight of the adjusting plate 7, save materials and facilitate the skin's ventilation, but also increase the friction between the adjusting plate 7 and the skin, which is beneficial to the stability of the entire compression device and is not easy to slide. In addition, the flange portion 16 is arranged at the edge of the adjusting plate 7. The upward curvature of the flange portion 16 leaves a gap between the bottom of the edge of the adjusting plate 7 and the skin, which effectively avoids the problem of compression damage to the skin.

[0042] By setting the sliding groove 10 and the lightweight groove 9, and utilizing the structural coordination between the sliding groove 10 and the bolt 5, the adjustment plate 7 can be stretched outward to extend the width of the compression device, thereby facilitating the support and fixation of the patient's wrist and improving the efficiency of postoperative recovery. The evenly distributed lightweight grooves 9 are opened through the adjustment plate 7 to reduce the material cost and the deadweight of the structure while meeting the structural strength, thereby effectively improving the practicability and economy of the equipment. Moreover, due to the setting of the lightweight groove 9, the roughness of the contact surface between the adjustment plate 7 and the skin is increased, thereby increasing the friction, effectively preventing shaking, and ensuring the effect of compression and hemostasis.

[0043] In this embodiment, if Figures 4 to 6 As shown, the sliding groove 10 is an L-shaped structure, and arc grooves are evenly distributed on the inner wall of the sliding groove 10. The spacing between the opposite arc grooves is adapted to the outer wall size of the bolt 5. A position spring piece 11 is fixedly connected at the intersection of two adjacent arc grooves, and an angle spring piece 13 distributed oppositely is fixedly connected at the center of the arc groove. The two adjacent position spring pieces 11 do not contact each other, and a first gap 12 is formed between the position spring piece 11 and the inner wall of the sliding groove 10. The two adjacent angle spring pieces 13 do not contact each other, and one side of the angle spring piece 13 is in contact with the inner wall of the sliding groove 10. A second gap 14 is formed between the angle spring piece 13 and the inner wall of the sliding groove 10, and a third gap 15 is formed between the other side of the angle spring piece 13 and the inner wall of the sliding groove 10. The centers of the two ends of the inner wall of the sliding groove 10 are fixedly connected with oppositely distributed angle spring pieces 13. The angle spring pieces 13 and the third gap 15 are both elastic curved surface structures. The bottom of the bolt 5 is fixedly connected to a circular protrusion 6 distributed in a circular array near the compression pad 22. The outer wall size of the circular protrusion 6 is larger than the arc space size formed between adjacent angle spring pieces 13, and the length size of the circular protrusion 6 is larger than the thickness size of the adjustment plate 7.

[0044] The cam 7 is preferably arranged on a circle, so that the adjustment plate 7 can be adjusted to the desired position by adjusting the position of the adjusting plate 7. When compression hemostasis is required, the compression pad 22 is first aligned with the puncture point to ensure that the bottom of the compression pad 22 is in close contact with the skin. The positional relationship between the adjustment plate 7 and the pressing plate 1 can be adjusted so that the adjustment plate 7 and the pressing plate 1 are perpendicular to each other, and then the cooperation between the circular protrusion 6 and the angle spring piece 13 is used to facilitate small angle adjustment until it is adjusted to a suitable fixed angle. When the adjustment plate 7 is rotated, the circular protrusion 6 squeezes the second gap 14. When the circular protrusion 6 is located at the center of the adjacent angle spring piece 13, the circular protrusion 6 squeezes the third gap 15 on both sides. With the elastic effect of the angle spring piece 13 itself, the circular protrusion 6 will be squeezed twice, which is conducive to the fixing of the circular protrusion 6 between the angle spring pieces 13. Then the short fixing belt 19 is passed between the index finger and the thumb to be fixedly connected to the short fixing belt 19 on the other side. The long fixing belt 17 is fixed in the direction parallel to the long axis of the pressing plate 1. The short fixing belt 19 and the long fixing belt 17 can form a fixation in two directions to ensure the effect of compression hemostasis.

[0045] By setting the position spring piece 11 and the first gap 12, not only the sliding and fixing of the adjustment plate 7 in the direction parallel to the long axis of the pressure plate 1 and perpendicular to the long axis of the pressure plate 1 are achieved, and the relative position relationship between the adjustment plate 7 and the pressure plate 1 is adjusted in multiple gears, but also the position spring piece 11 and the adjustment plate 7 are integrated, and the grooves are directly opened on the adjustment plate 7, which is not only simple and ingenious in structure, but also convenient and labor-saving in actual operation. In addition, the length of the circular protrusion 6 is greater than the thickness of the adjustment plate 7, which does not affect the adjustment under different compression pressures. The circular protrusion 6 and the bolt 5 are an integrated manufacturing structure. Such a setting makes the processing technology of the two simpler during the production process, easier to be produced, and reduces the manufacturer's capital investment. The circular protrusion 6 and the angle spring piece 13 are arranged, and the angle spring pieces 13 distributed opposite to each other are adapted to the outer contour size of the circular protrusion 6. The even-numbered circular protrusion 6 cooperates with the angle spring pieces 13 fixedly connected to the inner walls of the sliding groove 10 on both sides, so that the angle can be finely adjusted under the multi-gear adjustment of the adjustment plate 7, which can better adapt to the situation where the size of the hands of the individuals is large. Moreover, the short fixing belt 19 can be used alone for fixing, and then cooperate with the long fixing belt 17 to realize multi-position and multi-directional fixation, thereby ensuring that the compression position does not shift, and can effectively compress the bleeding point, thereby improving the hemostasis effect.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] When in use, confirm the position of the puncture point, align the compression pad 22 with the puncture point, ensure that the bottom of the compression pad 22 is in close contact with the skin, judge the distance between the patient's wrist and the puncture point, stretch the adjustment plate 7 in the direction close to the wrist, and then use the long fixing strap 17 and the short fixing strap 19 to fix the device to the patient's hand. Since the free ends of the short fixing strap 19 are both provided with Velcro, the second Velcro 20 has only a burr surface at the bottom, and the top and bottom of the third Velcro 21 are both burr surfaces. When fixing, first fit the top of the second Velcro 20 to the skin, and then connect the third Velcro 21 to the short fixing strap 19, and use the burrs at the bottom of the third Velcro 21 and the long fixing strap 17 for secondary fixation, which is convenient for the stability of the entire fixing strap. The adjustment plate 7 is provided with even Velcro. The evenly distributed lightweight grooves 9 can not only reduce the deadweight of the adjusting plate 7, save materials and facilitate skin ventilation, but also increase the friction between the adjusting plate 7 and the skin, which is beneficial to the stability of the entire compression device and is not easy to slide. In addition, the flange portion 16 is arranged at the edge of the adjusting plate 7. The upward curvature of the flange portion 16 leaves a gap between the bottom of the edge of the adjusting plate 7 and the skin, effectively avoiding the problem of compression damage to the skin. The arc-shaped inner wall size of the sliding groove 10 is matched with the outer wall size of the bolt 5, and the wavy arc setting of the sliding groove 10 can not only adjust the position of the adjusting plate 7 in multiple gears, but also utilize the elastic structure of the position spring piece 11, so that the adjusting plate 7 can produce a position under the tensile action of an external force under the elastic action. The bolt 5 is moved and recovers its deformation after the external force ends its stretching, and the bolt 5 is squeezed again, which is beneficial to the stability of the structure. The eight circular protrusions 6 of the circumferential array on the outer wall of the bolt 5 cooperate with the angle spring piece 13 fixedly connected on the inner wall of the sliding groove 10. When the puncture point of the distal radial artery needs to be compressed to stop bleeding, the compression pad 22 is first aligned with the puncture point to ensure that the bottom of the compression pad 22 is tightly fitted to the skin. The positional relationship between the adjustment plate 7 and the pressing plate 1 can be adjusted so that the adjustment plate 7 and the pressing plate 1 are perpendicular to each other, and then the cooperation between the circular protrusion 6 and the angle spring piece 13 is used to facilitate small angle adjustment until it is adjusted to a suitable fixed angle. When the adjustment plate 7 is rotated, the circular protrusion 6 squeezes the second gap 14 until the circular protrusion 6 is located in the middle of the adjacent angle spring piece 13. When the hand is at the center of the pressure plate 1, the circular protrusion 6 squeezes the third gap 15 on both sides, and the elastic effect of the angle spring piece 13 itself will produce a secondary squeezing on the circular protrusion 6, which is conducive to fixing the circular protrusion 6 between the angle spring pieces 13, and then the short fixing belt 19 is passed between the index finger and the thumb to be fixedly connected with the short fixing belt 19 on the other side, and the long fixing belt 17 is fixed in the direction parallel to the long axis of the pressure plate 1. The short fixing belt 19 and the long fixing belt 17 can form a fixation in two directions to ensure the effect of compression and hemostasis. This device can not only assist wrist braking when compressing and stopping bleeding at the puncture point of the classic radial artery approach, but also fix the distal radial artery puncture point that is difficult to fix, and better adapt to the situation where the size of the human hand is large and the individual differences are large.Improve the fixation efficiency of the compression hemostasis device on the puncture point.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0049] The above is only a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
