Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a compression hemostasis auxiliary nursing fixation device after cardiovascular interventional procedures. Background Technology

[0002] Cardiovascular interventional diagnosis and treatment has become a mature and mainstream minimally invasive treatment method in the fields of clinical cardiology and cardiac surgery. It is widely used in the clinical treatment of various cardiovascular-related diseases, such as coronary artery recanalization, minimally invasive intervention for arrhythmias, targeted dilation of vascular stenosis, and peripheral vascular lesion recanalization. During the operation, medical staff mostly choose the radial artery or femoral artery as the access site to establish a vascular puncture channel on the body surface to complete various minimally invasive diagnosis and treatment procedures. After the operation, the vascular wound at the puncture site is relatively fragile. It is necessary to keep the wound site tightly compressed for a long time, and at the same time, do a good job of stabilizing and limiting the position to protect it. This can effectively prevent a variety of common postoperative adverse complications such as postoperative bleeding at the puncture site, subcutaneous ecchymosis and hematoma, vascular pseudoaneurysm, and vascular displacement, ensure normal blood circulation in the patient's limbs after surgery, and accelerate the patient's postoperative recovery.

[0003] When existing compression hemostasis devices are used for hemostasis at the radial artery puncture site, the compression head and the base plate are mostly rigidly connected, or rely solely on rotating threads to achieve single-point locking. If the forearm rotates slightly during the postoperative immobilization period, the compression head is easily subjected to lateral shear force and slides along the skin surface, causing the pressure center to deviate from the original puncture point. Furthermore, it is impossible to complete rapid fine-tuning and repositioning while maintaining the established base pressure, which seriously affects the postoperative hemostasis effect and the stability of wearing and use. Summary of the Invention

[0004] The purpose of this invention is to provide a compression hemostasis auxiliary nursing fixation device after cardiovascular interventional surgery, so as to solve the problems of existing radial artery hemostasis devices being prone to displacement, unable to be quickly adjusted and reset under pressure, and having poor hemostasis and usage stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compression hemostasis auxiliary nursing fixation device after cardiovascular interventional surgery, comprising an arc-shaped wearing base plate;

[0016] Furthermore, the pressure regulating and applying mechanism also includes an adjusting plate, a pressure spring, and a protective sleeve. The adjusting plate is movably mounted on the bottom end of the pressure regulating nut via a bearing. The pressure spring is disposed between the bottom end of the adjusting plate and the bottom inner wall of the guide frame. The protective sleeve is fitted over the adjusting stud and covers the pressure spring.

[0017] Furthermore, the constant pressure mechanism includes a constant pressure airbag, a micro air pump, an electrically controlled air valve tube, and a pressure sensor. The constant pressure airbag is fixedly installed at the bottom end of the compression head, the micro air pump is connected and installed on one side of the top of the constant pressure airbag, the electrically controlled air valve tube is connected and installed on the other side of the top of the constant pressure airbag, and the pressure sensor is embedded in the middle of the top of the constant pressure airbag.

[0018] Furthermore, the tightening mechanism includes a tightening and fixing strap, a flexible skin-friendly pad, two lifting blocks, two first hook and loop fasteners, a second hook and loop fastener, and multiple ventilation holes.

The two first hook and loop fasteners are respectively embedded in the two ends of the side of the tightening and fixing strap furthest from the skin. The second hook and loop fastener is embedded in the middle of the side of the tightening and fixing strap furthest from the skin. The multiple ventilation holes are respectively opened on the tightening and fixing strap, the flexible skin-friendly pad, the two first hook and loop fasteners, and the second hook and loop fastener.

[0019] Furthermore, both the annular body and the elastic claw are made of medical-grade stainless steel or elastic copper alloy and are integrally formed.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] (1) The present invention enables the universal ball head to achieve multi-directional free deflection within the ball head seat through the coordinated work of the ball head seat, the universal ball head, the fine adjustment locking spring, the limiting retaining ring and the connecting column. The fine adjustment locking spring provides uniform damping for the universal ball head and achieves rapid angle positioning, thereby effectively offsetting the lateral shear force when the patient's forearm moves slightly, avoiding the compression head from slipping and deviating from the puncture point. Under the premise of maintaining the established basic compression pressure unchanged, it achieves rapid angle fine adjustment and positioning reset, significantly improving hemostasis stability and wearing reliability.

[0025] (2) The present invention achieves automatic closed-loop constant pressure control of the compression pressure by working together with a constant pressure airbag, a micro air pump, an electrically controlled air valve tube and a pressure sensor. The pressure sensor collects the compression pressure in real time and transmits it to the controller. When the pressure is too high, the controller drives the electrically controlled air valve tube to open and release the pressure. When the pressure is too low, the micro air pump is driven to replenish the constant pressure airbag and increase the pressure. This avoids excessive pressure affecting the blood supply to the limb or insufficient pressure causing bleeding, and improves the safety and intelligence of hemostasis.

[0026] (3) The present invention utilizes the coordinated work of the tightening and fixing strap, the flexible skin-friendly pad, the lifting block, the first hook and loop fastener, the second hook and loop fastener and the ventilation hole to achieve quick wearing and tightness adjustment of the device by using the tightening and fixing strap in conjunction with the first hook and loop fastener and the second hook and loop fastener. The flexible skin-friendly pad improves wearing comfort and reduces the risk of pressure sores. The lifting block facilitates wearing and positioning. The ventilation hole improves the breathability of long-term wear. The overall structure is easy to operate, fits firmly, and is comfortable and safe. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] As attached Figure 1 To be continued Figure 8 As shown:

[0040] Example 1:

[0041] This invention provides a compression hemostasis auxiliary nursing fixation device after cardiovascular intervention, including an arc-shaped wearing base plate 1, which adopts an ergonomic arc-shaped curved surface design to adapt to the physiological curvature of the wrist and improve wearing stability and fit.

[0042] The universal anti-deviation mechanism 2 is fixedly installed at the bottom center of the arc-shaped wearing base plate 1 to achieve multi-directional angle adaptive adjustment, counteract the shearing force caused by the micro-movement of the forearm, and prevent the pressure head 4 from deviating from the puncture point.

[0043] The universal anti-deviation mechanism 2 includes a ball head seat 21, a universal ball head 22, a fine-tuning locking spring 23, a limiting retaining ring 24, and a connecting column 25. The ball head seat 21 is fixedly installed at the bottom end of the arc-shaped wearing base plate 1. The universal ball head 22 is movably disposed in the inner cavity of the ball head seat 21. The fine-tuning locking spring 23 is fixedly installed on the inner cavity wall of the ball head seat 21. The limiting retaining ring 24 is fixedly installed at the bottom end of the ball head seat 21. The connecting column 25 is fixedly installed at the middle of the bottom end of the universal ball head 22.

[0044] The pressure regulating and applying mechanism 3 is fixedly installed at the bottom of the universal anti-deviation mechanism 2 and is used to manually adjust the basic compression pressure to meet the hemostasis strength requirements of different patients and different postoperative stages.

[0045] The compression head 4 is fixedly installed at the bottom of the pressure regulating and applying mechanism 3. As the core component for pressure transmission, it smoothly transmits mechanical pressure to the hemostatic area to ensure uniform pressure application.

[0046] The constant pressure mechanism 5 is fixedly installed at the bottom of the compression head 4 to monitor and maintain constant compression pressure in real time, so as to avoid pressure fluctuations from affecting the hemostasis effect.

[0047] The strap holes 6 are respectively opened on both sides of the top of the arc-shaped wearing base plate 1;

[0048] The fastening mechanism 7 is installed inside the two strap holes 6 to quickly fix the entire device to the patient's wrist, achieving adjustable tightness and stable wearing.

[0049] The controller 8 is fixedly installed at the top center of the arc-shaped wearing base plate 1. It is used to receive sensor signals and output control commands to realize the automated and intelligent operation of the device.

[0050] The fine-tuning locking spring 23 includes an annular body 231 and multiple elastic claws 232. The annular body 231 is fixedly installed on the lower side of the inner cavity wall of the ball head seat 21. The multiple elastic claws 232 are evenly distributed along the inner circumference of the annular body 231 to make the damping force uniform in the circumference and avoid excessive local force causing jamming.

[0051] The pressure regulating and applying mechanism 3 includes a guide frame 31, a limiting rod 32, an adjusting stud 33, and a pressure adjusting nut 34. The limiting rod 32 is fixedly installed in the middle of the bottom inner wall of the guide frame 31. The adjusting stud 33 is movably sleeved on the outer wall of the limiting rod 32 and is fixedly installed at the bottom end of the connecting column 25. The pressure adjusting nut 34 is threadedly installed on the upper side of the outer wall of the adjusting stud 33.

[0052] The pressure regulating and applying mechanism 3 also includes an adjusting plate 35, a pressure spring 36, and a protective sleeve 37. The adjusting plate 35 is movably mounted on the bottom end of the adjusting nut 34 via a bearing. The adjusting plate 35 rises and falls synchronously with the adjusting nut 34, uniformly compressing the pressure spring 36 and preventing the spring from being eccentrically stressed. The pressure spring 36 is located between the bottom end of the adjusting plate 35 and the bottom inner wall of the guide frame 31. The protective sleeve 37 is fitted over the adjusting stud 33 and covers the pressure spring 36.

[0053] Both the annular body 231 and the elastic claw plate 232 are made of medical-grade stainless steel or elastic copper alloy and are integrally molded. This material has good biocompatibility, corrosion resistance and elastic fatigue strength, making it suitable for long-term medical use. The annular body 231 has an annular thin sheet structure and does not contact the outer wall of the universal ball head 22. This structure avoids motion interference and ensures that the universal ball head 22 deflects smoothly without obstruction. The elastic claw plate 232 is petal-shaped and slightly curls inward and elastically contacts the outer wall of the universal ball head 22. This structure provides soft damping to achieve fine-tuning positioning without affecting normal deflection.

[0054] The protective sleeve 37 is designed as a folding structure, and the protective sleeve 37 does not contact the guide frame 31 or the pressure spring 36. The folding structure can freely extend and retract with the pressure spring 36 without generating additional resistance, ensuring sensitive pressure adjustment. The adjusting plate 35 has a groove that matches the frame wall of the guide frame 31, so that the guide frame 31 can limit the adjusting plate 35, restricting the adjusting plate 35 to only move up and down.

[0055] Working principle: In use, first place the arc-shaped wearing base plate 1 above the radial artery puncture point on the patient's wrist. Secure the device firmly through the strap hole 6 and the tightening mechanism 7 to prevent displacement or loosening during hemostasis. Then, rotate the pressure adjusting nut 34, causing it to move smoothly downwards along the adjusting stud 33. This pushes the adjusting plate 35 downwards simultaneously, compressing the pressure spring 36. The compressed pressure spring 36 generates a continuous and stable elastic force, which acts on the guide frame 31 and is then transmitted to the compression head 4. This allows the compression head 4 to apply adjustable, continuous, and uniform base pressure to the radial artery puncture site, achieving precise control of the compression force. During this process, the limiting rod 32 provides central guidance and radial limitation for the adjusting stud 33, preventing it from tilting, shaking, or jamming under pressure. The protective sleeve 37 folds and deforms synchronously with the extension and retraction of the pressure spring 36, effectively isolating the pressure spring. The spring 36 and external structure prevent dust and sweat from entering and affecting the spring's elasticity. When the patient's forearm rotates slightly during postoperative immobilization, the compression head 4 is subjected to lateral shear force. This shear force is transmitted to the connecting column 25, which in turn drives the universal ball head 22 to adaptively deflect in multiple directions within the ball head seat 21, effectively counteracting the offset tendency caused by external force. At this time, the elastic claw 232 retracts inward in a petal shape and elastically contacts the outer wall of the universal ball head 22, providing uniform and gentle damping force to the universal ball head 22, achieving rapid positioning and immediate reset after deflection. Ultimately, the compression head 4 can quickly complete angle fine-tuning and center reset while maintaining the predetermined basic compression pressure, always keeping the pressure center accurately aligned with the original puncture point, avoiding hemostasis failure due to slippage. Combined with the constant pressure mechanism 5 and controller 8, real-time pressure monitoring is achieved, significantly improving the stability, safety, and reliability of compression hemostasis after radial artery intervention.

[0056] Example 2:

[0057] This embodiment is basically the same as the previous embodiment, except that the constant pressure mechanism 5 includes a constant pressure airbag 51, a micro air pump 52, an electrically controlled air valve tube 53, and a pressure sensor 54. The constant pressure airbag 51 is fixedly installed at the bottom of the compression head 4. The constant pressure airbag 51 is made of flexible material and fits the skin flexibly to improve comfort and avoid local pressure injury. The micro air pump 52 is connected and installed on one side of the top of the constant pressure airbag 51 to inflate and pressurize the constant pressure airbag 51 to quickly increase the compression pressure to a safe threshold. The electrically controlled air valve tube 53 is connected and installed on the other side of the top of the constant pressure airbag 51 to quickly deflate and release pressure to prevent excessive pressure from affecting the blood circulation of the limbs. The pressure sensor 54 is embedded in the middle of the top of the constant pressure airbag 51. The pressure sensor 54 collects the compression pressure value in real time, and the signal acquisition is accurate and the response is rapid.

[0058] The miniature air pump 52, the electrically controlled air valve tube 53, and the pressure sensor 54 are all electrically connected to the controller 8 to achieve real-time signal transmission and rapid command execution, ensuring no delay in pressure regulation. The pressure sensor 54 is set as a miniature thin film structure, which is thin, has a high degree of fit, does not occupy installation space, and the pressure detection is closer to the actual pressure state.

[0059] Working principle: During use, the compression head 4 transmits the base pressure to the constant pressure balloon 51, allowing the constant pressure balloon 51 to flexibly conform to the patient's radial artery puncture site. The pressure sensor 54 collects the compression pressure data in real time and transmits it to the controller 8, achieving continuous and accurate monitoring of the pressure for hemostasis. When the pressure sensor 54 detects that the compression pressure is lower than the set safety threshold, the controller 8 immediately drives the micro air pump 52 to start working, inflating the constant pressure balloon 51 and increasing the compression force until the pressure returns to a reasonable range. When the pressure sensor 54 detects that the compression pressure is higher than the set safety threshold, the controller 8 quickly controls the electronically controlled air valve tube 53 to open and exhaust the excess gas in the constant pressure balloon 51, reducing the compression pressure and preventing excessive pressure from affecting blood circulation in the wrist. This ensures that the compression pressure is always stable within the preset safety range, guaranteeing effective hemostasis at the puncture site, preventing bleeding and hematoma formation, and avoiding discomfort such as limb numbness and ischemia caused by excessive pressure. This significantly improves the intelligence, safety, and patient comfort of postoperative compression hemostasis.

[0060] Example 3:

[0061] This embodiment is basically the same as the previous embodiment, except that the tightening mechanism 7 includes a tightening and fixing strap 71, a flexible skin-friendly pad 72, two lifting blocks 73, two first hook and loop fasteners 74, a second hook and loop fastener 75, and multiple ventilation holes 76. The two ends of the tightening and fixing strap 71 are respectively inserted into the two strap holes 6. The flexible skin-friendly pad 72 is embedded in the middle of the side of the tightening and fixing strap 71 closest to the skin, which can disperse the tightening pressure, avoid pressure marks and pain, and improve the wearing softness. The two lifting blocks 73 are respectively fixedly installed at the two ends of the side of the tightening and fixing strap 71 closest to the skin. The two first hook and loop fasteners 74 are respectively embedded in the two ends of the side of the tightening and fixing strap 71 away from the skin. The second hook and loop fasteners 75 are embedded in the middle of the side of the tightening and fixing strap 71 away from the skin. Multiple ventilation holes 76 are respectively opened on the tightening and fixing strap 71, the flexible skin-friendly pad 72, the two first hook and loop fasteners 74, and the second hook and loop fasteners 75. The ventilation holes 76 accelerate air circulation, expel heat and sweat, keep the skin dry, and reduce the risk of allergies.

[0062] The flexible, skin-friendly pad 72 is made of medical-grade silicone. Medical-grade silicone is non-toxic, non-irritating, and highly skin-friendly, making it suitable for prolonged skin contact. The first Velcro 74 is set as the hook and barb fastening surface, and the second Velcro 75 is set as the napped bonding surface. The second Velcro 75 and the first Velcro 74 are connected to each other. This mating structure makes it easy to attach and detach, has a large adjustment range, and provides a stable and reliable fixing effect.

[0063] Working principle: In use, first thread both ends of the tightening strap 71 through the threading holes 6 of the arc-shaped wearing base plate 1. The lifting blocks 73 at both ends smoothly stretch the tightening strap 71 to conform to the wrist contour, preventing curling or shifting during wear. Then, fasten the first Velcro 74 and the second Velcro 75 on the tightening strap 71 together. Adjusting the fastening position allows for quick and precise adjustment of the tightness, adapting to wrists of different sizes and ensuring a secure and stable fit. The flexible, skin-friendly medical silicone pad 72 directly contacts the patient's wrist skin; its soft and skin-friendly texture provides comfort. It effectively disperses the tightening pressure, avoiding excessive local pressure that could cause pressure marks, pain, or pressure sores, thus improving comfort during prolonged wear. Multiple ventilation holes 76 allow heat and sweat generated at the wearing site to escape in real time, keeping the skin dry and breathable, reducing stuffiness, allergies, and discomfort. Throughout the hemostasis process, the tightening mechanism 7 provides stable and reliable support for the device. Working in conjunction with the universal anti-deviation mechanism 2, the pressure regulating mechanism 3, and the constant pressure mechanism 5, it ensures that the compression head 4 and the constant pressure airbag 51 are consistently and accurately aligned with the puncture point, while also significantly improving the patient's wearing experience. This makes the device more stable, comfortable, and easy to use during long-term immobilization care.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
