Description

Technical Field

[0001] This disclosure relates to the field of medical compression technology, and more particularly to a compression component, a compression device after distal radial artery puncture, and a medical device. Background Technology

[0002] In the medical field, radial artery puncture is a common procedure used for arterial blood gas analysis or interventional coronary or cranial surgeries. After puncture, compression is usually applied to the puncture site to stop bleeding and prevent complications. In recent years, it has been found that compression hemostasis after puncture near the radial artery increases the risk of patient pain and discomfort, as well as radial artery occlusion. Therefore, distal radial artery puncture is becoming a new trend. However, due to the radial artery's location in the wrist, its course and position have certain unique characteristics, especially in the web between the thumb and index finger, making it difficult for traditional compression devices to achieve ideal compression.

[0003] Most radial artery compression devices currently available on the market are designed for the radial artery on the palm side. These devices typically use a flat compression pad or balloon to apply pressure perpendicular to the skin to achieve hemostasis. However, when the puncture point is on the back of the hand, because the radial artery runs at an angle to the skin surface, traditional vertical compression methods often fail to effectively compress the artery, and may even lead to uneven compression or displacement, resulting in complications such as bleeding and hematoma.

[0004] Furthermore, the shape and contour of the back of the hand are relatively complex, making it difficult for a simple flat compression pad to fit perfectly, which further reduces the compression effect. Therefore, there is an urgent clinical need for a compression device that can adapt to the special location and direction of the distal radial artery to improve hemostasis after puncture and patient comfort.

Figure 2A second-view overall structural schematic diagram of the compression assembly and the compression device corresponding to distal radial artery puncture according to an embodiment of the present disclosure is shown. Figure 3 A third-view structural schematic diagram of a compression assembly with an adjustable member and a compression device corresponding to distal radial artery puncture according to an embodiment of the present disclosure is shown. Figure 4 A front view of a compression assembly with an adjustable section and a fourth-angle view corresponding to a compression device after distal radial artery puncture, according to an embodiment of this disclosure, is shown. Figures 1 to 4 As shown, the compression assembly includes: a compression object fixing member, a compression block 3 disposed on one side of the compression object fixing member, and a support member 5; wherein, the compression block 3 is used to compress a set compression area corresponding to the object to be compressed; the support member 5 is used to support and maintain the deformation of the object to be compressed. This solves the technical problem that existing compression assemblies lack a support member and cannot support and maintain the deformation of the object to be compressed (e.g., a hand).

[0065] In the embodiments of this disclosure and other possible embodiments, the object to be compressed (e.g., a hand) is placed below the object to be compressed along the direction of the object to be compressed (the direction from the first connecting part 21 to the second connecting part 22), the support member 5 supports and maintains the deformation of the object to be compressed, and the compression block 3 compresses the set compression area corresponding to the object to be compressed to compress and stop bleeding.

[0066] In the embodiments of this disclosure and other possible embodiments, the object to be compressed is the back of the hand; the designated compression area is the distal radial artery. Furthermore, the hand is placed below the compression object fixing member along the direction of the first connecting portion 21 to the second connecting portion 22, the support member 5 supports and maintains the curvature of the back of the hand, and the compression block 3 compresses the designated compression area corresponding to the object to be compressed, thereby compressing and stopping bleeding in the distal radial artery on the back of the hand.

[0067] In embodiments of this disclosure, the support member 5 is configured as a protrusion formed on one side of the pressing object fixing member. The end face of the protrusion that contacts the object to be pressed is configured to approximate the shape of the outer surface of the object to be pressed when a set pressing area is applied to the object. For example, if the outer surface of the object to be pressed is curved, then the end face of the protrusion that contacts the object to be pressed is also configured to be curved.

[0068] In embodiments of this disclosure and other possible embodiments, the protrusion may be configured as a cube or a column. Further, when the object to be compressed is the back of the hand, the side of the cube or column that contacts the object is configured to approximate the shape of the outer surface of the back of the hand when compressing the distal radial artery corresponding to the back of the hand. For example, if the side of the protrusion that contacts the object is configured to compress the distal radial artery corresponding to the back of the hand, and the outer surface of the back of the hand is an arcuate surface, then the side of the protrusion that contacts the object is also configured as an arcuate surface.

[0069] In an embodiment of this disclosure, the compression assembly is characterized by further comprising: an adjusting member 1 connected to the compression block 3; wherein the adjusting member 1 is used to adjust the distance between the compression block 3 and the compression fixing member.

[0070] In the embodiments of this disclosure and other possible embodiments, the object to be compressed (e.g., a hand) is placed below the object to be compressed along the direction from the first connecting portion 21 to the second connecting portion 22 of the object to be compressed, and the support member 5 supports and maintains the deformation of the object to be compressed; the compression block 3 compresses the set compression area corresponding to the object to be compressed, and when compressing the set compression area corresponding to the object to be compressed to stop bleeding, the distance between the compression block 3 and the object to be compressed is adjusted by the adjusting member 1 so as to better utilize the compression block 3 to apply pressure to the set compression area so as to better compress and stop bleeding in the set compression area.

[0071] For example, when the distance between the pressing block 3 and the pressing object fixing member decreases, the pressure applied by the pressing block 3 to the set pressing area increases; conversely, when the distance between the pressing block 3 and the pressing object fixing member increases, the pressure applied by the pressing block 3 to the set pressing area decreases.

[0072] In the embodiments of this disclosure and other possible embodiments, when the object to be compressed (e.g., a hand) is placed below the object to be compressed along the direction from the first connecting portion 21 to the second connecting portion 22 of the object to be compressed, the support member 5 supports and maintains the deformation of the object to be compressed; when the compression block 3 needs to compress the set compression area corresponding to the object to be compressed, and compress the set compression area corresponding to the object to be compressed to stop bleeding, the distance between the compression block 3 and the object to be compressed is adjusted by the adjusting member 1, so that the distance between the compression block 3 and the object to be compressed is reduced, the pressure applied by the compression block 3 to the set compression area is increased, and the set compression area corresponding to the object to be compressed is compressed to stop bleeding. When the pressure to stop bleeding is completed on the designated pressure area corresponding to the object to be compressed, the distance between the pressure block 3 and the object fixing member is adjusted by the adjusting member 1. The distance between the pressure block 3 and the object fixing member is increased, and the pressure applied by the pressure block 3 to the designated pressure area is reduced. As a result, the object to be compressed (e.g., a hand) can be released from the support of the support member 5 and from the pressure of the pressure block 3 on the designated pressure area corresponding to the object to be compressed.

[0115] In embodiments of this disclosure, a medical device is also provided, comprising: the compression component as described above and the distal radial artery puncture compression device as described above.

[0116] In the embodiments of this disclosure and other possible embodiments, for traditional transradial artery interventional surgery, the compression device after proximal radial artery puncture is used to compress and stop bleeding after proximal radial artery puncture. Due to the position of the distal radial artery, the compression direction is inclined, and the existing compression device is not applicable. In order to realize a compression device applicable to distal radial artery puncture, this application proposes a compression device that can achieve inclined compression. It utilizes two mutually separable first flexible fixing bands 41 and second flexible fixing bands 42 (compression bands) to be arranged in a cross configuration, so that the intersection of the two mutually separable first flexible fixing bands 41 and second flexible fixing bands 42 (compression bands) is exactly located at the distal radial artery position. Then, a compression block 3 is set at the intersection position. The distal radial artery position is compressed and hemostasis is achieved by using a nut 12, a screw 11, and a fixing plate 2. The screw 11 is set on the top surface of the fixing plate 2, and the nut 12 is used to adjust the fixing plate 2 and the compression position. The bottom surface of the fixing plate 2 is shaped to accommodate the compression block 3, and the bottom surface of the compression block 3 is set in an arc shape to fit the shape of the back of the hand. This type of distal radial artery puncture compression device is suitable for use in the tilted position of the thenar eminence on the back of the hand. The cross-shaped compression bands can fix the compression block 3 under the fixation plate 2. The arc-shaped design of the compression block 3 also makes it fit better against the back of the hand.

[0117] In embodiments of this disclosure and other possible embodiments, conventional compression pads or airbags cannot adapt to the inclined position of the distal radial artery. Therefore, this disclosure employs cross-shaped compression bands (two separable first flexible fixation bands 41 and second flexible fixation bands 42). This design allows the crossing points of the compression bands to be precisely positioned at the radial artery location on the back of the hand, thereby achieving effective compression hemostasis. Its innovation lies in achieving effective compression hemostasis of the distal radial artery, solving the problem that conventional compression devices cannot adapt to the inclined position of the distal radial artery.

[0118] In the embodiments of this disclosure and other possible embodiments, in order to ensure that the compression band can be stably fixed on the back of the hand, it includes: nut 12, screw 11 and fixing plate 2; wherein, screw 11 is disposed on the top surface of fixing plate 2, and by cooperating with nut 12, the distance between fixing plate 2 and compression position (setting compression area or distal radial artery) can be adjusted to ensure that compression block 3 can fit tightly against the back of the hand (compressing the object to be compressed).

[0119] In the embodiments of this disclosure and other possible embodiments, the arc-shaped design of the bottom surface of the pressure block 3 can better adapt to the shape of the back of the hand. This disclosure designs the bottom surface of the pressure block 3 as arc-shaped. This design not only improves the fit between the pressure block 3 and the back of the hand, but also increases the user's comfort.

[0120] In the embodiments disclosed herein and other possible embodiments, the first flexible fixation band 41 and the second flexible fixation band 42 (compression band) are made of medical-grade silicone material, which is soft, comfortable, and durable. Meanwhile, the width and thickness of the compression band are carefully designed to ensure that sufficient pressure is provided without causing excessive stress on the back of the hand.

[0121] In the embodiments of this disclosure and other possible embodiments, the screw 11 and nut 12 have a large adjustment range to accommodate the hand sizes and shapes of different individuals. Furthermore, the fixing plate 2 is made of a lightweight and high-strength medical alloy material, ensuring safety during use while reducing overall weight.

[0122] In the embodiments disclosed herein and other possible embodiments, the curved bottom surface of the compression block 3 is precisely calculated and designed to ensure optimal fit with the back of the hand. Simultaneously, the compression block 3 is made of a soft and elastic medical material to further enhance user comfort.

[0123] In the embodiments and other possible embodiments of this disclosure, the compression component and distal radial artery puncture post-compression device proposed in this disclosure are reusable, reducing medical costs and environmental pollution. Easy to clean and disinfect: The material selection and design of the compression component and distal radial artery puncture post-compression device take into account the need for easy cleaning and disinfection, ensuring safety and hygiene in use. Ergonomic design: The entire compression component and distal radial artery puncture post-compression device are designed with full consideration of ergonomic principles, allowing users to feel more comfortable and natural during use.

[0124] In summary, the compression component and distal radial artery puncture compression device of this disclosure solve the problem of traditional compression devices being unable to adapt to the tilted position of the distal radial artery through innovative features such as a unique cross compression band design, an adjustable fixation device, and optimized shape and material selection of the compression block 3. These innovations collectively constitute the maximum protection scope of this disclosure and bring significant beneficial effects.

[0125] The compression component and distal radial artery puncture compression device disclosed herein, through unique design and innovative technology, significantly improve hemostasis and patient comfort after puncture. The function and effects of this disclosure will be explained in detail below.

[0126] First, this disclosure achieves precise compression of the distal radial artery through a cross-shaped compression band design. Traditional compression devices often cannot adapt to the inclined position of the distal radial artery, resulting in poor compression effect and potentially causing unnecessary complications. The cross-shaped compression band design of this disclosure ensures that the compression force is applied directly and accurately to the puncture site, thereby effectively stopping bleeding and reducing the risk of postoperative bleeding.

[0127] Secondly, the fixation device design used in this disclosure is not only simple and easy to operate, but also allows for fine-tuning according to the patient's actual condition. Through the combination of nut 12, screw 11, and fixing plate 2, medical staff can easily adjust the pressure and position, ensuring that the compression block 3 closely conforms to the shape of the patient's hand. This personalized adjustment method not only improves the hemostatic effect but also greatly enhances patient comfort.

[0128] Furthermore, the curved design of the compression block 3 is another highlight of this disclosure. This design fully considers ergonomic factors, allowing the compression block 3 to better adapt to the shape of the back of the hand. Compared with traditional flat compression methods, the curved compression block 3 can distribute the pressure more evenly, avoiding excessive pressure on local tissues, thereby reducing the patient's pain and discomfort.

[0129] Furthermore, this disclosure also offers significant economic and social benefits. From an economic perspective, the manufacturing cost of this disclosure is not high, yet its effectiveness is significantly enhanced, reducing medical costs while improving the efficiency of medical resource utilization. From a social perspective, the application of this disclosure helps improve the quality of medical services, enhance patients' medical experience, and further build a harmonious doctor-patient relationship.

[0130] In summary, this disclosure significantly improves hemostasis and patient comfort after distal radial artery puncture through innovative methods such as a unique cross-compression band design, an adjustable fixation device, and an arc-shaped compression block 3. These innovations not only demonstrate the technological advancements of this disclosure in the field of medical devices but also bring tangible convenience and benefits to clinical practice.

[0131] In embodiments of this disclosure and other possible embodiments, the first flexible fixation band 41 and the second flexible fixation band 42 (compression band) are made of a soft and elastic material, such as medical silicone or elastic fabric. The two compression bands cross at the distal radial artery location to form an adjustable compression point.

[0132] In the embodiments of this disclosure and other possible embodiments, screw 11 is fixed to the top surface of the fixing plate 2, and nut 12 is used to adjust the distance between the fixing plate 2 and the pressing position, thereby achieving precise control of the pressing force.

[0133] In embodiments of this disclosure and other possible embodiments, the compression block 3 is disposed on the bottom surface of the fixing plate 2, and its bottom surface is arc-shaped to better conform to the shape of the back of the hand. The compression block 3 may be made of hard rubber or other medical materials to ensure hemostasis while providing patient comfort.

[0134] In the embodiments and other possible embodiments disclosed herein, 1. Preparation stage: First, select appropriate compression bands and compression blocks 3 according to the size and shape of the patient's hand. Ensure that the length and width of the compression band can cover and fix it on the back of the hand, while the arc-shaped bottom surface of the compression block 3 can fit tightly against the back of the hand. 2. Installation and adjustment: Place the crossed compression bands on the back of the hand, ensuring that the intersection point is above the radial artery puncture point. Then, adjust the distance between the fixing plate 2 and the back of the hand by adjusting the nut 12, thereby controlling the compression force. During this process, the patient's reaction needs to be closely observed to ensure that the compression force is neither too strong nor too weak. 3. Fixation and hemostasis: After the compression force is adjusted to an appropriate level, use medical tape or other fixing devices to fix the compression bands on the back of the hand. At this time, the compression block 3 should fit tightly above the distal radial artery puncture point to achieve effective hemostasis. 4. Monitoring and adjustment: During the hemostasis process, the patient's reaction and hemostasis effect need to be monitored regularly. If the compression force is found to be insufficient or too strong, the nut 12 should be adjusted in time to change the compression force. Simultaneously, it is also important to observe the skin condition around the puncture site to prevent pressure sores or other complications. 5. Removal and Follow-up Care: After hemostasis is achieved, the compression band can be gradually loosened and the fixation device removed. During removal, it is important to observe whether there is bleeding or oozing at the puncture site. After removal, provide necessary follow-up care and observation to the patient to ensure their safety and comfort. Through the detailed description of this specific embodiment, it can be seen that the distal radial artery puncture compression device provided by this disclosure has the advantages of simple structure, convenient operation, and good hemostasis effect. At the same time, its adjustable compression force and design that fits the back of the hand greatly improve the patient's comfort.

[0135] In the embodiments disclosed herein and other possible embodiments, to realize this distal radial artery puncture compression device, the following materials and tools are first required: 1. Flexible and durable fabric or elastic material for making the crisscrossing compression bands. 2. Rigid plastic or lightweight metal material for making the fixation plate 2. 3. Arc-shaped compression block 3 material, such as silicone or rubber, to ensure conformity to the shape of the back of the hand. 4. Fasteners such as small nuts 12 and screws 11. 5. Sewing tools for sewing the compression bands. 6. Basic fabrication and assembly tools, such as screwdrivers, glue, or welding equipment.

[0136] In the embodiments of this disclosure and other possible embodiments, the compression band is made as follows: 1. Using flexible fabric or elastic material, two compression bands of appropriate length are cut according to the design dimensions; 2. Fixing points are set at appropriate positions on the compression bands, which will be used for subsequent connection with the fixing plate 2; 3. The edges of the compression bands are reinforced to improve durability.

[0137] In the embodiments of this disclosure and other possible embodiments, the fixing plate 2 and the pressure block 3 are assembled as follows: 1. The fixing plate 2 is made of hard plastic or lightweight metal to ensure that it has a certain rigidity and stability; 2. A screw 11 is installed at the center of the top surface of the fixing plate 2 for subsequent adjustment; 3. The pressure block 3 is installed at the center of the bottom surface of the fixing plate 2, and the bottom surface of the pressure block 3 should be processed into an arc shape to adapt to the shape of the back of the hand; 4. The pressure block 3 is firmly fixed to the fixing plate 2 by means of glue or welding.

[0138] In embodiments of this disclosure and other possible embodiments, the compression device is assembled as follows: 1. Place the two compression bands crosswise, ensuring the crossing point is located at the distal radial artery; 2. Place the fixing plate 2 below the crossing point of the compression bands, ensuring the compression block 3 is aligned with the radial artery; 3. Use the nut 12 and screw 11 to tightly connect the fixing plate 2 and the compression bands together. By adjusting the position of the nut 12, the compression force of the compression block 3 on the distal radial artery can be adjusted; 4. Check the overall structure of the compression device for stability, ensuring that it will not loosen or shift during use.

[0139] In the embodiments and other possible embodiments disclosed herein, the instructions for use are as follows: 1. Before use, ensure the compressor is clean and hygienic; 2.

During use, closely observe the patient's reaction and the hemostatic effect, and adjust the compression force promptly; 5. After use, clean and disinfect the compressor for future use. This compressor has an inclined compression function, which can effectively stop bleeding and reduce patient pain. Furthermore, its simple structure, convenient operation, low cost, and reusability also give it broad application prospects.

[0140] In the embodiments disclosed herein and other possible embodiments, firstly, 1. Prepare the necessary materials and tools, including compression bands, fixation plate 2, compression block 3, nuts 12, screws 11, and necessary fabrication tools. 2. Fabricate the compression band cross structure: Cross the two compression bands at an appropriate angle, ensuring the cross point is located at the expected position of the distal radial artery. The key to this step is ensuring that the cross angle matches the tilt angle of the distal radial artery to achieve the most effective compression. 3. Install fixation plate 2 and compression block 3: Install fixation plate 2 below the cross point of the compression bands, with compression block 3 mounted on the bottom surface of fixation plate 2. The bottom surface of compression block 3 is designed to be arc-shaped to better conform to the shape of the back of the hand. This step requires precise adjustment of the position of fixation plate 2 to ensure that compression block 3 can accurately align with the radial artery on the back of the hand. 4. Adjust the fixation device: Use nuts 12 and screws 11 to adjust the distance between fixation plate 2 and the compression position. The purpose of this step is to ensure that compression block 3 can compress the radial artery on the back of the hand with appropriate pressure and angle to achieve hemostasis. 5. Testing and Adjustment: Before actual use, the compressor needs to be tested and adjusted. The hemostasis process after puncture can be simulated to check whether the compression block 3 can effectively compress the radial artery and observe the hemostatic effect. If necessary, the nut 12 and screw 11 can be fine-tuned to optimize the compression effect and comfort. 6. Use and Monitoring: In actual use, apply the compressor to the back of the hand after puncture and continuously monitor the hemostatic effect. If any problems or discomfort are found, adjustments should be made immediately or medical professional assistance should be sought.

[0142] In the embodiments disclosed herein and other possible embodiments, the effect was evaluated as follows: Through practical application and testing, the compressor significantly improved hemostasis after distal radial artery puncture. Its tilted compression design and arc-shaped compression block 3 make compression more precise and comfortable, effectively reducing patient pain and discomfort. Simultaneously, the adjustability of the compressor makes it suitable for different patient hand shapes and puncture situations, improving its practicality and applicability.

[0143] In summary, this specific implementation method details the fabrication and use of the compression device after distal radial artery puncture, highlighting its innovation and practicality. Through practical application and effect evaluation, the significant advantages of this compression device in improving hemostasis and patient comfort have been demonstrated.

[0144] Application prospects of the embodiments and other possible embodiments disclosed herein: With the continuous advancement of medical technology, radial artery puncture is increasingly widely used in interventional diagnosis and treatment, such as coronary angiography and percutaneous coronary intervention (PCI). However, traditional radial artery puncture compressors often cannot effectively adapt to the special location of the distal radial artery, which brings inconvenience to medical staff and may also increase patient pain and discomfort. The distal radial artery puncture compressor proposed in this disclosure, through its innovative cross-compression band design and arc-shaped compression block 3, effectively solves the problem that traditional compressors cannot adapt to the inclined position of the distal radial artery. This innovation not only improves the convenience and comfort of medical operations, but also has the potential to reduce post-puncture complications, such as bleeding and hematoma, thereby improving patient satisfaction and safety.

[0145] From an industry application perspective, the compressor disclosed herein has broad market prospects. With the increasing number of cardiovascular interventional surgeries, the demand for more humane and precise medical devices is constantly growing. The innovative design of the distal radial artery puncture compressor precisely responds to this market demand, providing medical staff with a more convenient and efficient operating tool, while also bringing a better medical experience to patients.

[0146] Furthermore, this disclosure has potential social and economic value. By reducing post-puncture complications, it can lower patients' medical costs and recovery time, thereby alleviating the burden on the healthcare system. Simultaneously, improving the efficiency and safety of medical procedures also helps enhance the reputation of medical institutions and patient satisfaction, further promoting the development of the healthcare industry.

[0147] With increasing health awareness and advancements in medical technology, the demand for precise and efficient medical devices will continue to grow. This disclosure presents an innovative distal radial artery puncture compression device that not only solves the problems of existing technologies but also demonstrates broad application prospects and market potential. In the future, with further promotion and application of the product, it is expected to bring more convenience and value to the medical industry.

[0148] In summary, the distal radial artery puncture compression device proposed in this disclosure has significant application prospects in the medical field. It can not only improve the convenience and safety of medical operations, but also bring a better medical experience to patients and promote the sustainable development of the medical industry.

[0149] In the embodiments disclosed herein and other possible embodiments, the shape and contour of the back of the hand are relatively complex, making it difficult for a simple planar compression pad to fit completely, which further reduces the compression effect. Therefore, there is an urgent clinical need for a compression device that can adapt to the special location and direction of the distal radial artery to improve hemostasis after puncture and patient comfort.

[0150] To achieve this goal, this disclosure provides an in-depth analysis of the anatomical structure of the distal radial artery and the hemostasis requirements after puncture. We found that a cross-shaped compression band better adapts to the shape of the back of the hand and the course of the radial artery. By applying pressure at the cross-section, it ensures that the compression force acts directly on the artery, thereby improving the hemostatic effect. Simultaneously, this disclosure also designs a special support 5 and an arc-shaped compression block 3 to ensure the stability and comfort of the compressor.

[0151] In summary, existing radial artery puncture compression devices have significant shortcomings and limitations in their application on the dorsum of the hand. To address this issue, this disclosure proposes a novel design for a distal radial artery puncture compression device, aiming to improve hemostasis and patient experience through innovative structural design and material selection. This proposed solution is based not only on a thorough analysis and understanding of current technologies but also on comprehensive consideration of clinical needs and actual patient usage.

[0152] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technological improvements of the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
