Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a compression hemostat. Background Art

[0002] In recent years, cardiovascular interventional techniques have rapidly developed due to their minimal invasiveness, rapid recovery, minimal pain, and proven clinical efficacy. Percutaneous coronary intervention (PCI) is one of the most widely used interventional procedures for cardiovascular disease. The femoral artery in the groin region is shallow and large, making it easily palpable and accessible. This facilitates postoperative compression and hemostasis, reducing the risk of complications. Therefore, femoral artery puncture has become the most commonly used access route for cardiovascular interventional procedures.

[0003] After percutaneous coronary intervention, compression is required to stop bleeding at the puncture site. Traditional compression devices (such as manual compressors and mechanical compression bands) rely on the medical staff's experience to determine the location of the vascular puncture site. However, due to factors such as subcutaneous tissue coverage and differences in the puncture needle's insertion angle, the projected position of the vascular puncture site on the body surface is difficult to accurately locate. This makes the setting position of the compression device prone to deviation, resulting in insufficient compression of the vascular puncture site area, increasing the risk of continued blood seepage into the subcutaneous tissue, forming bruises, hematomas, and even pseudoaneurysms.

[0004] Therefore, after percutaneous coronary intervention, how to accurately locate the position of the blood vessel puncture site during the compression hemostasis operation is a technical problem that needs to be solved urgently in the existing technology. Summary of the Invention

[0005] The present invention aims to address the problem of conventional compression devices (e.g., manual compressors and mechanical compression bands) that rely on medical personnel's experience to determine the location of a vascular puncture site. However, due to factors such as subcutaneous tissue coverage and variations in the needle's insertion angle, the precise location of the vascular puncture site on the body surface is difficult to determine. This can easily lead to deviations in the compression device's placement, resulting in insufficient compression of the vascular puncture site and an increased risk of continued blood seepage into the subcutaneous tissue, leading to bruising, hematomas, and even pseudoaneurysms. The present invention provides a compression hemostat.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A compression hemostat comprises a support component, a hemostatic component, and a measuring component; the support component comprises two uprights, a carrier plate, and a support plate; the ends of the uprights that contact human skin are provided with a base; the carrier plate is disposed between the two uprights, the length of the uprights being adjustable; and a level gauge is further provided on the carrier plate for measuring the levelness of the carrier plate; the support plate is configured to conform to the skin of the human leg behind the puncture point; a strap is provided between the carrier plate and the support plate, the strap being configured to connect the carrier plate and the support plate into an integral structure;

[0008] The hemostatic component includes an extrusion head and a push rod, the push rod extending vertically toward one side of the human skin, the length of the push rod being adjustable, a slide groove being further provided along the length direction of the supporting plate, the push rod being clamped in the slide groove, the push rod being able to slide along the slide groove on the surface of the supporting plate, a scale ruler being further provided at the edge of the slide groove, the scale ruler being used to indicate the position of the push rod on the supporting plate; the extrusion head being provided at one end of the push rod facing the human skin, the extrusion head and the push rod being rotatably connected and matched;

[0009] The measuring component includes a suspension rod and an angle measurer. The suspension rod is connected to the supporting plate and extends vertically toward one side of the human skin. The angle measurer is slidably connected to the suspension rod and is used to measure the angle between the sheath and the human skin.

[0010] Preferably, a guide component is further provided on the surface of the angle measurer, and the guide component includes a fixed column and an introduction tube. The fixed column is arranged perpendicular to the surface of the angle measurer, and the fixed column is a telescopic rod structure. The fixed column and the angle measurer are rotatably connected. The end of the fixed column is also provided with a plug-in groove, and the introduction tube is inserted into the plug-in groove. The introduction tube can slide in the plug-in groove. The diameter of the introduction tube matches the inner diameter of the sheath tube, and the introduction tube is used to extend into the subcutaneous tissue of the human body along the sheath tube.

[0011] Preferably, a pointer is further provided on the fixing column, and the pointer is in contact with the surface of the angle measuring device.

[0012] Preferably, the connecting pipe is configured as a hollow tube structure.

[0013] Preferably, the measuring component and the carrying plate are connected in a detachable manner.

[0014] Preferably, the extrusion head includes a fixed seat, a first pressure member and a second pressure member, the fixed seat is connected to the push rod, the first pressure member and the second pressure member are connected to the fixed seat, the first pressure member and the second pressure member are arranged at intervals along the same horizontal line, the first pressure member is arranged on one side of the measuring component, the first pressure member is used to squeeze the skin tissue corresponding to the femoral artery puncture port, and the second pressure member is used to squeeze the skin tissue corresponding to the vascular segment behind the femoral artery puncture port, so that the blood flow toward the femoral artery puncture port is slowed down.

[0015] Preferably, the second pressure member is a retractable structure, and has a first shape and a second shape. In the first shape, the length of the second pressure member is greater than the length of the first pressure member; in the second shape, the length of the second pressure member is less than the length of the first pressure member.

[0016] When compressing the femoral artery to stop bleeding, the first pressure member is first aligned with the skin tissue corresponding to the femoral artery puncture site and pressure is applied, and then the second pressure member is adjusted to extend to form the first shape;

[0017] When the pressure on the femoral artery is reduced, the pressure applied by the first pressure member to the skin tissue corresponding to the femoral artery puncture site is kept unchanged, and the length of the second pressure member is shortened to form a second shape.

[0018] Preferably, a pressure sensor is further provided on the side of the first pressure-applying member that contacts human skin.

[0019] Preferably, the base and the support plate are configured as arc structures.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. The compression hemostat of the present invention, during the operation of locating a patient's vascular puncture site, measures the angle at which the sheath penetrates the human subcutaneous tissue using the measuring component, then slowly withdraws the sheath. When the kinetic energy and flow rate of the blood flowing out of the sheath are observed to decrease, withdrawal is stopped. At this time, the end of the sheath is located at the femoral artery puncture site, the length of the external segment of the sheath is measured, and the length of the internal segment of the sheath penetrating the human subcutaneous tissue is calculated. The cosine function is used to locate the position of the femoral artery puncture site projected on the human body surface, thereby achieving precise positioning of the vascular puncture site, improving the accuracy and reliability of compression hemostasis, and reducing the risk of continued blood seepage into the subcutaneous tissue to form bruises, hematomas, or even pseudoaneurysms.

[0022] 2. The compression hemostat described in the present invention, when compressing the femoral artery to stop bleeding, increases the pressure on the vascular segment behind the femoral artery puncture site by adjusting the second pressure-applying member to extend to form the first shape, thereby further reducing the flow rate of blood in the femoral artery. On the one hand, it makes it easier for the blood to coagulate under the action of thrombin, further improving the hemostasis efficiency; on the other hand, the pressure of the first pressure-applying member on the skin tissue corresponding to the femoral artery puncture site can be appropriately reduced, thereby alleviating the patient's pain and further improving the comfort during treatment; in addition, the second pressure-applying member is configured as a retractable structure, which also facilitates medical staff to flexibly adjust the pressure on the vascular segment behind the femoral artery puncture site according to the patient's actual situation and hemostasis needs, thereby achieving precise control of the hemostasis effect;

[0023] When reducing pressure on the femoral artery, by shortening the length of the second pressure-applying member to form a second configuration, the pressure on the skin tissue behind the blood vessel is gradually reduced, thus avoiding prolonged, high-intensity pressure that could cause insufficient blood supply to the patient's lower limbs, leading to numbness, coldness, and other discomfort, thereby improving the comfort and safety of the present invention during use. Furthermore, during the process of reducing pressure on the femoral artery, the first pressure-applying member maintains constant pressure on the skin tissue corresponding to the femoral puncture site. This prevents the blood clot formed at the femoral artery puncture site from rupturing and falling off due to the sudden reduction in pressure, leading to further bleeding. This further improves the reliability and safety of the present invention's hemostasis.

[0024] 3. The compression hemostatic device described herein is configured such that the airway cooperates with the airbag. When the second pressure member extends too long, lifting the entire support member, causing the pressure exerted by the first pressure member on the skin tissue corresponding to the femoral artery puncture site to be less than the internal pressure of the airbag, air, under the action of air pressure, overflows from the gap between the first pressure member and the skin tissue into the suction cup. As the air accumulated in the suction cup continues to increase, the suction cup's adsorption function eventually fails, and the air escapes into the external environment. At this point, the air in the airbag loses and deflates, shortening the length of the second pressure member. When the pressure exerted by the first pressure member on the skin tissue corresponding to the femoral artery puncture site exceeds the internal pressure of the airbag, the airway opening is resealed. This ensures that the first pressure member effectively compresses the blood vessel puncture site, improving the hemostatic effect. Furthermore, the suction cup configuration described in this embodiment prevents displacement of the first pressure member during the compression hemostatic process, further improving the reliability and stability of hemostasis.

[0038] Example 1: Figures 1 to 4 As shown, a compression hemostat according to the present invention includes a support component 1, a hemostatic component 2, and a measuring component 3; the support component 1 includes two uprights 4, a supporting plate 5, and a supporting plate 6; the end of the upright 4 in contact with human skin is provided with a base 7; the supporting plate 5 is arranged between the two uprights 4, and the length of the uprights 4 is adjustable; the supporting plate 5 is further provided with a level measuring device 8 for measuring the levelness of the supporting plate 5; the supporting plate 6 is used to fit the skin of the human leg on the back of the puncture point; a strap 10 is provided between the supporting plate 5 and the supporting plate 6, and the strap 10 is used to connect the supporting plate 5 and the supporting plate 6 into an integrated structure;

[0039] The hemostatic component 2 includes an extrusion head 11 and a push rod 12, the push rod 12 extends vertically toward one side of the human skin, the length of the push rod 12 is adjustable, and a slide groove 13 is further provided along the length direction of the supporting plate 5, the push rod 12 is clamped in the slide groove 13, the push rod 12 can slide along the slide groove 13 on the surface of the supporting plate 5, and a scale is further provided on the edge of the slide groove 13, which is used to indicate the position of the push rod 12 on the supporting plate 5; the extrusion head 11 is provided at one end of the push rod 12 facing the human skin, and the extrusion head 11 and the push rod 12 are rotatably connected;

[0040] The measuring component 3 includes a suspension rod 14 and an angle measurer 15. The suspension rod 14 is connected to the supporting plate 5 and extends vertically toward one side of the human skin. The angle measurer 15 is slidably connected to the suspension rod 14 and is used to measure the angle between the sheath and the human skin.

[0041] By using the compression hemostatic device described in the present invention, during the operation of locating the patient's vascular puncture site, the angle at which the sheath penetrates the human subcutaneous tissue is measured by the measuring component 3, and then the sheath is slowly pulled out. When the kinetic energy and flow rate of the blood flowing out of the sheath are observed to decrease, the pulling out of the sheath is stopped. At this time, the end of the sheath is located at the femoral artery puncture site, the length of the external segment of the sheath is measured, and the length of the internal segment of the sheath penetrating the human subcutaneous tissue is calculated. The cosine function can be used to locate the position of the femoral artery puncture site projected on the human body surface, thereby achieving precise positioning of the vascular puncture site, improving the accuracy and reliability of compression hemostasis, and reducing the risk of blood continuously seeping into the subcutaneous tissue to form bruises, hematomas, and even pseudoaneurysms.

[0042] Specifically, in this embodiment, when installing the support component 1, the two vertical rods 4 are placed on either side of the skin puncture point. The height of the vertical rods 4 is adjusted to keep the support plate 5 parallel to the body surface. Subsequently, the support plate 5 is calibrated using the level gauge 8 until it reaches a completely horizontal state. Afterwards, the support plate 6 is tightly placed against the back of the human leg and secured to the support plate 6 and the support plate 5 using the straps 10.

[0043] A slider is provided on the pushing rod 12, and the slider is clamped in the sliding groove 13. The pushing rod 12 and the slider are threadedly connected. When using, medical staff can adjust the length of the pushing rod 12 below the supporting plate 5 according to actual needs, which can change the force of the extrusion head 11 pressing the human skin tissue; a limit bolt is also provided on the side of the pushing rod 12 above the supporting plate 5, which is used to lock the sliding cooperation between the slider and the sliding groove 13; the scale provided on the edge of the sliding groove 13 provides an intuitive indication for medical staff, which is convenient for quickly and accurately adjusting the position of the pushing rod 12, further ensuring that the extrusion head 11 accurately presses the skin tissue corresponding to the blood vessel puncture port;

[0044] To measure the angle of the sheath, first straighten the stretched sheath to a straight position. Then, adjust the angle measuring device 15 by sliding it along the suspension rod 14 so that its center passes through the sheath's central axis. At this point, the angle α between the sheath and the skin is read using the angle measuring device 15. The sheath is slowly withdrawn, and withdrawal is stopped when the kinetic energy and flow rate of the blood flowing out of the sheath decrease. At this point, the end of the sheath is located at the femoral artery puncture site. The length of the sheath's external segment is measured, recorded as L1. The length of the segment of the sheath penetrating the subcutaneous tissue is calculated as L2 by subtracting L1 from the total length of the sheath. The projected position of the femoral artery puncture site on the body surface is calculated using the cosine function formula: d = L2 × cosα. The hemostatic component 2 is then slid, aligning the extrusion head 11 with the projected position of the puncture site on the body surface. Pressure is applied to this position to achieve precise compression and hemostasis of the femoral artery puncture site.

[0045] Example 2: Figure 1 、 Figure 2 and Figure 4 As shown, a compression hemostat according to the present invention, based on the above-mentioned embodiment, is further provided with a guide component 16 on the surface of the angle measuring device 15. The guide component 16 includes a fixed column 17 and an introduction tube 18. The fixed column 17 is arranged perpendicular to the surface of the angle measuring device 15. The fixed column 17 is a telescopic rod structure. The fixed column 17 and the angle measuring device 15 are rotatably connected. The end of the fixed column 17 is further provided with a plug-in groove 19. The introduction tube 18 is inserted into the plug-in groove 19. The introduction tube 18 can slide in the plug-in groove 19. The diameter of the introduction tube 18 matches the inner diameter of the sheath tube. The introduction tube 18 is used to extend along the sheath tube into the subcutaneous tissue of the human body.

[0046] Specifically, in this embodiment, when measuring the angle of the sheath, the length of the fixed column 17 is first adjusted so that the projection of the connecting tube 18 on the leg coincides with the position of the skin puncture. The connecting tube 18 is then inserted into the subcutaneous tissue of the human body along the sheath. During this process, the fixed height of the angle measuring device 15 on the suspension rod 14 is simultaneously adjusted to ensure that the center of the angle measuring device 15 passes through the central axis of the sheath. After the connecting tube 18 is inserted into the subcutaneous tissue of the human body along the sheath, the angle between the sheath and the human skin is read by the angle measuring device 15. In this embodiment, the connecting tube 18 serves to guide and correct the sheath, preventing it from bending or twisting, thereby improving the accuracy of angle measurement. At the same time, the connecting tube 18 also fixes the position of the sheath, preventing it from shifting during angle measurement, further ensuring the reliability of the measurement results. Furthermore, the connecting tube 18 can assist medical personnel in reading the measurement data of the angle measuring device 15, reducing measurement difficulty and improving measurement efficiency.

[0047] As a preferred embodiment, based on the above approach, a pointer 20 is further provided on the fixing post 17, and the pointer 20 is in contact with the surface of the angle measuring device 15. With this structural arrangement, medical personnel can quickly and accurately read the angle between the sheath and the human skin by observing the position of the pointer 20, thereby further improving measurement efficiency.

[0048] As a preferred embodiment, based on the above-mentioned method, the introduction tube 18 is further configured as a hollow tube structure. This structure prevents blood in the sheath from flowing back into the artery when the introduction tube 18 is pushed into the sheath, reducing the risk of blood infection. In addition, the hollow tube structure of the introduction tube 18 makes it smoother when inserted into the sheath, reducing the difficulty of operation and improving the convenience of use of the present invention.

[0049] As a preferred embodiment, on the basis of the above-mentioned manner, further, the measuring component 3 and the supporting plate 5 are connected and matched in a detachable manner.

[0050] Specifically, in this embodiment, the suspension rod 14 is magnetically connected to the support plate 5. This structural arrangement facilitates medical personnel to remove the measuring component 3 from the support plate 5 after completing the sheath angle measurement. This prevents the measuring component 3 from occupying space and interfering with the subsequent compression and hemostasis operation at the puncture site, thereby enhancing the flexibility and ease of use of the present invention. Furthermore, this structural arrangement facilitates medical personnel to clean and disinfect the measuring component 3, improving the hygiene and safety of medical procedures.

[0051] Example 3: Figure 5 and Figure 6 As shown, the compression hemostat described in the present invention, on the basis of the above method, further, the extrusion head 11 includes a fixed seat 21, a first pressure member 22 and a second pressure member 23, the fixed seat 21 is connected to the push rod 12, the first pressure member 22 and the second pressure member 23 are connected to the fixed seat 21, the first pressure member 22 and the second pressure member 23 are arranged at intervals along the same horizontal line, the first pressure member 22 is arranged on the side of the measuring component 3, the first pressure member 22 is used to squeeze the skin tissue corresponding to the femoral artery puncture port, and the second pressure member 23 is used to squeeze the skin tissue corresponding to the vascular segment behind the femoral artery puncture port, so that the blood flow toward the femoral artery puncture port is slowed down.

[0052] In this embodiment, the first pressure member 22 and the second pressure member 23 are configured to cooperate during the compression and hemostasis process at the puncture site. The first pressure member 22 and the second pressure member 23 can work together to achieve comprehensive compression of the femoral artery puncture site and the vascular segments behind it, effectively slowing the flow of blood to the puncture site, promoting the coagulation process, and improving the hemostatic effect. At the same time, the first pressure member 22 and the second pressure member 23 cooperate to perform compression and hemostasis. When achieving the same hemostatic effect, the required pressure is less, thereby reducing the patient's pain and the risk of skin tissue damage caused by excessive pressure.

[0053] As a preferred embodiment, based on the above embodiment, further, the second pressure member 23 is a retractable structure, and the second pressure member 23 has a first shape and a second shape. In the first shape, the length of the second pressure member 23 is greater than the length of the first pressure member 22; in the second shape, the length of the second pressure member 23 is less than the length of the first pressure member 22;

[0054] When compressing the femoral artery to stop bleeding, first align the first pressure member 22 with the skin tissue corresponding to the femoral artery puncture site and apply pressure, then adjust the second pressure member 23 to extend it to form the first shape;

[0055] When the pressure on the femoral artery is reduced, the pressure applied by the first pressure member 22 to the skin tissue corresponding to the femoral artery puncture site is kept unchanged, and the length of the second pressure member 23 is shortened to form a second shape.

[0056] Specifically, in this embodiment, the second pressure member 23 includes a telescopic inner rod 24 and a sleeve 25. The sleeve 25 is connected to the fixed seat 21. An airbag 26 is provided in the sleeve 25. The telescopic inner rod 24 is connected to the airbag 26. In actual use, the length of the telescopic inner rod 24 is adjusted by inflating or deflating the airbag 26. In this embodiment, when the femoral artery is compressed to stop bleeding, the second pressure member 23 is adjusted to extend to form the first shape, thereby increasing the pressure on the vascular segment behind the femoral artery puncture site, thereby further reducing the flow rate of the femoral artery blood. On the one hand, the blood is more easily coagulated under the action of thrombin, further improving the hemostasis efficiency; on the other hand, the pressure of the first pressure member 22 on the skin tissue corresponding to the femoral artery puncture site can be appropriately reduced, thereby alleviating the patient's pain and further improving the comfort during treatment; in addition, the second pressure member 23 is configured as a retractable structure, which also facilitates medical staff to flexibly adjust the pressure on the vascular segment behind the femoral artery puncture site according to the patient's actual situation and hemostasis needs, thereby achieving precise control of the hemostasis effect;

[0057] When reducing pressure on the femoral artery, by shortening the length of the second pressure member 23 to form a second configuration, the pressure on the skin tissue behind the blood vessel is gradually reduced, thus avoiding prolonged, high-intensity pressure that can cause insufficient blood supply to the patient's lower limbs, leading to numbness, coldness, and other discomfort, thereby improving the comfort and safety of the present invention during use. Furthermore, during the process of reducing pressure on the femoral artery, the first pressure member 22 maintains constant pressure on the skin tissue corresponding to the femoral puncture site, preventing the blood clot formed at the femoral artery puncture site from rupturing and falling off due to the sudden reduction in pressure, leading to further bleeding. This further improves the reliability and safety of the present invention's hemostasis.

[0058] As a preferred embodiment, on the basis of the above method, further, the second pressure member 23 includes a telescopic inner rod 24 and a sleeve 25, the sleeve 25 is connected to the fixed seat 21, an airbag 26 is provided in the sleeve 25, the telescopic inner rod 24 is connected to the airbag 26, and the telescopic inner rod 24 can move in the sleeve 25 with the expansion and contraction of the airbag 26, thereby realizing the adjustment of the length of the second pressure member 23.

[0059] An air duct 27 is also provided inside the first pressure member 22 and the fixing seat 21. The opening of the air duct 27 is provided at the end of the first pressure member 22 in contact with human skin. The air duct 27 is connected to the airbag 26. A suction cup 28 is also provided at the end of the first pressure member 22 in contact with human skin. The suction cup 28 is used to adsorb on the surface of human skin.

[0060] In this embodiment, considering that when the second pressure member 23 is extended too long, the second pressure member 23 may lift the supporting member 1 as a whole, resulting in insufficient pressure on the femoral artery puncture port by the first pressure member 22, thereby causing poor hemostasis effect. Based on this, in this embodiment, the air channel 27 is configured to cooperate with the airbag 26. When the second pressure member 23 extends too long, lifting the entire support member 1, so that the pressure exerted by the first pressure member 22 on the skin tissue corresponding to the femoral artery puncture port is less than the internal pressure of the airbag 26, air pressure causes air to overflow from the gap between the first pressure member 22 and the skin tissue into the suction cup 28. As the air accumulated in the suction cup 28 continues to increase, the suction function of the suction cup 28 eventually fails, and the air escapes into the external environment. At this time, the air in the airbag 26 loses air and deflates, shortening the length of the second pressure member 23. When the pressure exerted by the first pressure member 22 on the skin tissue corresponding to the femoral artery puncture port is greater than the internal pressure of the airbag 26, the opening of the air channel 27 is resealed. This ensures that the first pressure member 22 effectively compresses the blood vessel puncture port, improving the hemostatic effect. In addition, the provision of the suction cup 28 in this embodiment can also prevent the first pressure member 22 from being displaced during the compression hemostasis process, thereby further improving the reliability and stability of hemostasis.

[0061] As a preferred embodiment, on the basis of the above embodiment, a pressure sensor is further provided on the side of the first pressure-applying member 22 that contacts the human skin.

[0062] In this embodiment, the pressure sensor is used to monitor in real time the pressure applied by the first pressure member 22 to the human skin tissue. In practice, medical personnel can precisely control the pressure applied by the first pressure member 22 to the skin tissue corresponding to the femoral artery puncture site by observing the pressure sensor reading, thereby ensuring effective compression of the vascular puncture site. This also prevents the situation in which excessive pressure from the second pressure member 23 could lift the first pressure member 22, resulting in insufficient pressure on the femoral artery puncture site and poor hemostasis. This further improves the hemostatic efficacy and safety of the present invention.

[0063] Example 4: Figure 1 As shown, the compression hemostat described in the present invention is based on the above method, and further, the base 7 and the support plate 6 are configured as an arc structure.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
