[0002] The cardiovascular system is an important system of the human body, mainly composed of the heart and blood vessels, which is responsible for transporting blood to various tissues and organs throughout the body, providing them with oxygen and nutrients, and taking away metabolic waste. During internal cardiovascular surgery, it is often necessary to press the legs to stop bleeding, especially arterial bleeding, and it is necessary to apply precise and sufficient pressure to the bleeding point to achieve a hemostatic effect; however, the existing technology generally uses gauze (such as the technical solutions disclosed in patents with application numbers CN202110919519.X, CN202220147304.0, etc.) to press and stop bleeding. This method of pressing and stopping bleeding forms a large area of pressing, which is not targeted and cannot ensure that the local pressing force is in place. It may also cause damage to the surrounding skin, affecting the patient's postoperative recovery. Summary of the Invention

[0017] The compression hemostasis device for cardiovascular surgery is provided with two groups of local compression components, so that the compression plate of one group of local compression components presses the patient's hemostasis area to be pressed for a period of time, and then slightly relaxes the local compression. At the same time, the compression plate of the other group of local compression components can locally press the proximal side of the injured area to temporarily block the blood flow at the proximal end, and release the compression plate and the nursing layer for pressing the patient's hemostasis area to be pressed, thereby reducing the pressure of long-term local compression on the patient's hemostasis area and allowing the skin of the patient's hemostasis area to be pressed to breathe freely, greatly reducing the stuffiness and discomfort caused by long-term compression, achieving alternating compression, and increasing the oxygen supply time of the skin, which is beneficial to wound recovery.

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] In the above description of the present invention, it should be noted that the terms "one side," "the other side," and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0033] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.

[0034] See also Figure 1-9 The present invention provides a technical solution: a compression hemostasis device for cardiovascular surgery, comprising a base 1, a base rod 2 connected to the base 1 at one end, a suspension rod 3 arranged vertically and fixedly connected at the upper end to the other end of the base rod 2, and a local pressing component 4 connected to the lower end of the suspension rod 3. The base 1 is provided with a through hole 13 for the legs to pass through, and the base rod 2 extends along the opening direction of the through hole 13. The local pressing component 4 is located in front of the through hole 13, which includes a horizontal plate 41 arranged horizontally and connected at one end to the lower end of the suspension rod 3, a pressure rod 42 arranged vertically and threadedly connected to the other end of the horizontal plate 41, and a pressure plate 43 detachably connected to the lower end of the pressure rod 42.

[0035] During use, the patient's leg is passed through the through hole 13, and the base 1 is fixed to the patient's leg, so that the local pressing component 4 is located on the proximal side of the base 1 (referring to the local pressing component 4 being closer to the patient's heart relative to the base 1). At this time, the pressure plate 43 of the local pressing component 4 is located directly above the part to be pressed for hemostasis. Then the pressure rod 42 is rotated so that the pressure plate 43 moves toward the part to be pressed for hemostasis and presses the part to be pressed for hemostasis until the desired pressing and hemostasis effect is achieved, and the rotation of the pressure rod 42 is stopped. The local pressurized hemostasis method formed by the pressure plate 43 replaces the method of wrapping and pressing a large area with gauze in the prior art. The pressing and hemostasis by the pressure plate 43 is more targeted, which can improve the technical problems of the prior art method of using gauze to press a large area for hemostasis, which is not targeted, cannot ensure that the local pressing force is in place, and may cause damage to the surrounding skin, affecting the patient's postoperative recovery.

[0036] In the present invention, the pressure plate 43 is detachably connected to the lower end of the pressure rod 42. Specifically, an adhesive layer 431 is fixedly connected to the lower side of the pressure rod 42. The adhesive layer 431 can be a Velcro to adhere and install the pressure plate 43 for easy disassembly and replacement.

[0037] The lower side of the pressure plate 43 is curved to conform to the curved outer surface of the leg, increasing the contact area. A protective layer 432 is affixed to the lower side of the pressure plate 43. The protective layer 432 can be a hemostatic material such as gauze. The protective layer 432 contacts the area to be pressed, effectively achieving a hemostatic effect.

[0038] Based on the above examples, please refer to Figure 1-3 The base 1 includes a mounting plate 11 and a fastening belt 12 fixedly connected to the mounting plate 11 at one end. The other end of the fastening belt 12 is detachably connected to the other end of the mounting plate 11, such as by a buckle, so that the mounting plate 11 and the fastening belt 12 jointly form a through hole 13. In the present invention, one end of the base rod 2 is connected to the mounting plate 11 of the base 1.

[0039] The lower side of the mounting plate 11 facing the fastening band 12 is curved and secured with a flexible layer (not shown) to conform to the curved outer surface of the leg, increasing the contact area and ensuring comfort. A clearance hole 113 is formed along the lower side of the mounting plate 11 facing the fastening band 12, extending along the opening of the through hole 13. This allows the patient's aorta to pass through the clearance hole 113 when the base 1 is strapped and secured to the patient's leg, minimizing discomfort.

[0040] Among them, see Figure 1 At least two groups of bases 1 are arranged at intervals, and one end of the base rod 2 is connected to two mounting plates 11 at the same time, so that after the two groups of bases 1 are installed on the patient's legs, the indirect support stability of the local pressing component 4 is improved, and the pressure plate 43 of the local pressing component 4 is ensured to form an effective pressing effect on the patient's hemostasis area to be pressed.

[0041] See also Figure 5 and Figure 9 In this embodiment, the lower end of the pressure rod 42 is coaxially rotatably connected to the adapter 421 , and the pressure plate 43 is detachably connected to the lower side of the adapter 421 .

[0042] When the pressure plate 43 is moved toward the area to be pressed for hemostasis and the area to be pressed for hemostasis is pressed, since the adapter 421 is coaxially connected to the pressure rod 42, during the pressurization process, force can be applied to the adapter 421 to make the adapter 421 and the pressure plate 43 rotate relative to the pressure rod 42 at the same time, thereby ensuring that the pressure plate 43 is stationary, thereby preventing the pressure plate 43 from rotating and causing adverse effects on the patient during the pressurization process; similarly, when the pressure rod 42 is rotated in the opposite direction to make the pressure plate 43 and the nursing layer 432 away from the patient so that the nursing layer 432 can be replaced, the adapter 421 and the pressure plate 43 can be rotated relative to the pressure rod 42 at the same time, thereby ensuring that the pressure plate 43 and the nursing layer 432 are stationary, thereby preventing the nursing layer 432 from rotating and causing pulling damage to the patient's healing wound during the pressurization process.

[0043] Among them, the lower end of the pressure rod 42 is an inverted "T" shape, and a stepped hole is opened on the upper side of the adapter 421. The lower end of the pressure rod 42 is adapted and rotatably connected to the stepped hole of the adapter 421 to realize the rotational installation between the pressure rod 42 and the adapter 421.

[0044] A plurality of balls 422 are rotatably mounted on the lower side of the pressure rod 42 . The balls 422 are evenly distributed circumferentially around the axis of the pressure rod 42 and are rollingly mounted on the lower side of the pressure rod 42 . The rolling surfaces of the balls 422 abut against the adapter 421 .

[0045] When the pressure plate 43 and the nursing layer 432 are moved toward or away from the patient's part to be pressed to stop bleeding by rotating the pressure rod 42, the adapter 421, the pressure plate 43 and the nursing layer 432 are rotated relative to the pressure rod 42 at the same time. Under the action of the ball 422, rolling friction is generated, and the relative rotation between the adapter 421 and the pressure rod 42 will be smoother.

[0046] An annular rotation groove is provided on the inner wall of the stepped hole of the pressure rod 42 and / or the adapter 421 , and the ball 422 is adapted to be rotatably installed in the annular rotation groove to form a rotation path of the ball 422 through the annular rotation groove.

[0047] See also Figure 1 、 Figure 2 as well as Figure 5 In this embodiment, two groups of local pressing components 4 are provided and are arranged at intervals along the opening direction of the through hole 13 .

[0048] On the basis of the above embodiment, the two pressing plates 43 are arranged at intervals along the opening direction of the through hole 13 .

[0049] In this way, when pressing the part of the patient to be pressed for hemostasis, the pressure plate 43 and the nursing layer 432 relatively close to the base 1 press the part of the patient to be pressed for hemostasis. At this time, the other pressure plate 43 and the nursing layer 432 are located at the proximal end, relatively close to the patient's heart. During the long-term compression hemostasis process, after the pressure plate 43 and the nursing layer 432 relatively close to the base 1 press the patient's hemostatic area for a period of time (such as 10-15 minutes), the local compression can be slightly relaxed by rotating the pressure rod 42 in the opposite direction, and the proximal compression can be started at the same time or before, that is, by rotating the proximal pressure rod 42, the proximal pressure plate 43 and the nursing layer 432 press the blood vessels on the proximal side of the hemostatic area to be pressed to stop bleeding, temporarily blocking the blood flow at the proximal end, and releasing the pressure plate 43 and the nursing layer 432 for pressing the patient's hemostatic area to be pressed, thereby reducing the pressure of long-term local compression on the patient's hemostatic area and allowing the skin of the patient's hemostatic area to be pressed to breathe freely, greatly reducing the stuffiness and discomfort caused by long-term compression. After maintaining proximal pressure for a few minutes, the local pressure is strengthened again, and the pressure plate 43 and the nursing layer 432 closer to the base 1 are pressed again to stop bleeding on the patient's hemostatic area, and the proximal pressure plate 43 and the nursing layer 432 are released. In this way, the alternating pressure can effectively reduce the ischemic time of the local tissue and increase the oxygen supply time of the skin, which is beneficial to wound recovery.

[0050] Of course, during the first alternating compression, it is necessary to ensure that the patient's hemostasis site has initially achieved hemostasis. To this end, clinically, medical staff can closely observe changes in the color, temperature, and sensation of local tissues. If ischemic symptoms such as skin pallor, cyanosis, or numbness occur, the compression strategy should be adjusted immediately. In addition, whether it is local compression or proximal compression, prolonged continuous compression should be avoided. Prolonged compression may cause local tissue ischemia or even necrosis. It is recommended to relax the compression for 1-2 minutes every 15-30 minutes to restore local blood circulation.

[0051] See also Figure 5 and Figure 8 In this embodiment, two annular grooves are provided at the lower end of the suspension rod 3; two horizontal plates 41 are vertically spaced apart, and a rotation hole 411 is provided through one end of each plate, and the hole walls of the two rotation holes 411 are respectively rotatably mounted with the bottom walls of the two annular grooves.

[0052] When the pressure plate 43 and the nursing layer 432 relatively close to the base 1 are used to press and stop bleeding on the patient's hemostatic area by rotating the pressure rod 42, the positions of the corresponding pressure plate 43 and the nursing layer 432 can be adjusted by rotating the horizontal plate 41 relatively close to the base 1 relative to the suspension rod 3 to ensure that the injured area is accurately pressed to stop bleeding. At the same time, when the proximal end (i.e., the other pressure plate 43 and the nursing layer 432 relatively far from the base 1) are used to alternately press and stop bleeding on the blood vessels proximal to the injured area, the positions of the corresponding other pressure plate 43 and the nursing layer 432 can be adjusted by rotating the other horizontal plate 41 relatively far from the base 1 relative to the suspension rod 3 to ensure that accurate alternating pressing and stopping bleeding are achieved.

[0053] In addition, when replacing the nursing layer 432 for applying pressure to the injured area to stop bleeding, the two horizontal plates 41 can be rotated 180° at the same time. At this time, the nursing layer 432 to be replaced is at the proximal end, which is convenient for replacing the nursing layer 432 to be replaced, and the nursing layer 432 originally at the proximal end is located directly above the injured area. At this time, the pressure rod 42 can be rotated to make the nursing layer 432 located directly above the injured area apply pressure to the injured area to stop bleeding in time, thereby realizing rapid hemostasis and rapid replacement of nursing operations.

[0054] The bottom walls of the two annular grooves are circumferentially provided with a plurality of anti-rotation holes 31, and the hole walls of the two rotating holes 411 are provided with sliding grooves 412; the two groups of local pressing components 4 also include anti-rotation parts 44, and the two anti-rotation parts 44 include an anti-rotation rod 441, an anti-rotation plate 442 fixedly connected to the middle end of the anti-rotation rod 441, and a spring 443 sleeved on the anti-rotation rod 441. The two anti-rotation rods 441 are slidably connected to the corresponding sliding grooves 412, and one end is adapted and inserted into the corresponding anti-rotation hole 31. The anti-rotation hole 31 is a trumpet hole. One end of the two springs 443 is fixedly connected to the corresponding anti-rotation plate 442, and the other end is pressed against the bottom of the corresponding sliding groove 412

[0055] The anti-rotation hole 31 is a trumpet-shaped hole with a circular cross-section, with the diameter gradually decreasing from its opening to the closed bottom. One end of the anti-rotation rod 441 is conically shaped to facilitate smooth insertion into the anti-rotation hole 31. When the cross plate 41 rotates, the anti-rotation rod 441 is guided by the wall of the anti-rotation hole 31 and can be smoothly withdrawn from the anti-rotation hole 31.

[0056] That is, when the pressure position of the corresponding pressure plate 43 and nursing layer 432 is adjusted by rotating the horizontal plate 41, one end of the corresponding anti-rotation rod 441 is withdrawn from the anti-rotation hole 31 under the guidance of the hole wall of the anti-rotation hole 31, and the anti-rotation rod 441 and the anti-rotation rod 441 simultaneously slide in the slide groove 412, and the corresponding spring 443 is compressed. After the adjustment is in place, the horizontal plate 41 stops rotating, and the spring 443 recovers, pushing the corresponding anti-rotation rod 441 and the anti-rotation rod 441 to slide forward simultaneously. One end of the anti-rotation rod 441 extends into the anti-rotation hole 31, and the corresponding horizontal plate 41 is limited by the anti-rotation hole 31, thereby ensuring that the position of the corresponding pressure plate 43 and nursing layer 432 remains unchanged.

[0057] The sliding groove 412 is a stepped groove, and the edge end side of the anti-rotation plate 442 abuts against the groove wall of the sliding groove 412, so that the anti-rotation rod 441 can only move axially.

[0058] See also Figure 5 and Figure 7 In this embodiment, a hanging groove 281 is provided on the lower side of the other end of the base rod 2, and the hanging groove 281 is an annular groove; the two groups of local pressing components 4 also include diagonal support rods 45, the upper ends of the two diagonal support rods 45 are rotatably connected to the hanging groove 281, and the lower ends are fixedly connected to the upper sides of the two horizontal plates 41.

[0059] The corresponding transverse plate 41 is supported by the diagonal bracing rod 45, thereby improving the installation structural strength of the transverse plate 41 and the corresponding pressure rod 42. When the transverse plate 41 is rotated, the corresponding diagonal bracing rod 45 rotates in the hanging groove 281.

[0060] The cross section of the hanging groove 281 is stepped or dovetail-shaped, and the upper ends of the two diagonal support rods 45 are adapted dovetail structures or stepped structures to ensure that the two diagonal support rods 45 will not fall out of the hanging groove 281 during rotation.

[0061] See also Figure 3 and Figure 4 In this embodiment: the base rod 2 includes a screw rod 21 and a plurality of nuts 22 threadedly connected to the screw rod 21. One end of the screw rod 21 is slidably connected to the base 1 along the opening direction of the through hole 13. The number of nuts 22 is twice the number of the base 1, and nuts 22 are tightly pressed on both sides of the base 1. The upper end of the suspension rod 3 is fixedly connected to the other end of the screw rod 21.

[0062] The number of nuts 22 is twice the number of bases 1 . For example, when there are two bases 1 , there are four nuts 22 , which are distributed on both sides of the base 1 respectively.

[0063] After the base 1 is installed, the position of the local compression assembly 4 can be adjusted by loosening the nuts 22, allowing the screw 21 to slide axially relative to the mounting plate 11 of the base 1, so that the compression plate 43 is directly above the injured area to be compressed. After adjustment, each nut 22 is rotated in the opposite direction so that it abuts the corresponding mounting plate 11 of the base 1 to fix the position of the screw 21, thereby ensuring that the compression plate 43 is directly above the injured area to be compressed, facilitating subsequent stable compression and hemostasis.

[0064] In this embodiment: the base 1 is provided with an arc-shaped groove 111 along the opening direction of the through hole 13, and a plurality of first limiting holes 112 are provided on one side of each base 1, and each first limiting hole 112 is spaced apart along the groove direction of the arc-shaped groove 111; the base rod 2 also includes a limiting plate 23 rotatably connected to the screw rod 21, the number of limiting plates 23 is equal to the number of bases 1, and is arranged corresponding to the base 1, one end of the limiting plate 23 is coaxially rotatably connected to the corresponding nut 22, and the other end is fixedly connected to the first limiting rod 24, and the first limiting rod 24 is inserted into the corresponding first limiting hole 112.

[0065] The arc-shaped groove 111 is formed on the mounting plate 11 of the base 1 .

[0066] A push-pull groove 221 is provided on one side of the nut 22. The push-pull groove 221 is an annular groove, and its cross-section is stepped or dovetail-shaped. A push-pull block is formed on one side of the limiting plate 23 and is adapted to and rotatably connected to the push-pull groove 221 to achieve stable rotational installation of the limiting plate 23.

[0067] After the base 1 is installed in place, the position of the local pressing assembly 4 can be adjusted by loosening the nut 22 to allow the screw 21 to slide axially relative to the mounting plate 11 of the base 1. At the same time, the screw 21 can be moved within the arcuate groove 111 to adjust the position of the local pressing assembly 4 so that the pressure plate 43 is directly above the injured area to be pressed. After adjustment, each nut 22 is rotated in the opposite direction so that the first limiting rod 24 is inserted into the corresponding first limiting hole 112. At the same time, the limiting plate 23 is pressed against the corresponding mounting plate 11 of the base 1 to fix the position of the screw 21, thereby ensuring that the pressure plate 43 is directly above the injured area to be pressed, facilitating subsequent stable pressure hemostasis operations.

[0068] At this time, the first limiting hole 112 is used to limit the screw rod 21 , and the nut 22 is tightened to prevent the screw rod 21 from moving relative to the mounting plate 11 of the base 1 , thereby keeping the position of the screw rod 21 fixed.

[0069] The first limiting hole 112 is a trumpet hole, so as to facilitate smooth insertion of the first limiting rod 24 .

[0070] See also Figure 5 and Figure 6 In this embodiment, the base rod 2 also includes a vertical rod 25, an extension plate 26 and a second limiting rod 27. The vertical rod 25 is vertically arranged and the lower end is fixedly connected to the other end of the screw rod 21. An anti-rotation hole 251 is opened on the upper side of the vertical rod 25. One end of the extension plate 26 is rotatably connected to the upper end of the vertical rod 25, and a plurality of second limiting holes 261 that can be connected to the anti-rotation hole 251 are opened on the side of one end. The second limiting rod 27 is inserted into the connected anti-rotation hole 251 and the second limiting hole 261, and the upper end of the suspension rod 3 is fixedly connected to the other end of the extension plate 26.

[0071] One end of the extension plate 26 is cylindrical. A circular hole is formed through the upper end of the vertical rod 25 to allow for the rotatable mounting of one end of the extension plate 26. The inner wall of the circular hole defines an inner groove, into which one end of the extension plate 26 fits and rotatably mounts, preventing the extension plate 26 from separating from the vertical rod 25. An anti-rotation hole 251 communicates with the inner groove. Multiple second stopper holes 261 are circumferentially spaced along one end of the extension plate 26.

[0072] When the position of the local pressing assembly 4 is adjusted by moving the screw 21 within the arcuate groove 111, the second limiting rod 27 can be simultaneously withdrawn, so that the extension plate 26 drives the local pressing assembly 4 to rotate relative to the vertical rod 25, so that the pressure plate 43 is directly above the injured area to be pressed. After the adjustment is completed, the second limiting rod 27 is inserted into the connected anti-rotation hole 251 and the second limiting hole 261.

[0073] The vertical rod 25 is arranged vertically, and the extension plate 26 is arranged horizontally so that an installation space for installing the suspension rod 3 and the local pressing component 4 is formed between the vertical rod 25 and the extension plate 26, which is convenient for medical staff to operate the local pressing component 4.

[0074] A lifting ring 28 is fixedly connected to the other end of the extension plate 26 , and a lifting groove 281 is defined in the lifting ring 28 .
