Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a device for compressing forearm hematoma after coronary artery surgery. Background Art

[0002] Percutaneous Coronary Intervention (PCI) is an important non-surgical method for treating coronary artery disease. The procedure involves making a small incision on the patient's skin, inserting a special catheter into the blood vessel, and advancing it along the blood vessel to the coronary artery of the heart to perform operations such as balloon dilatation and stent implantation, thereby restoring or improving blood flow and relieving symptoms of myocardial ischemia. With the advancement of medical technology, PCI has become an effective means of treating cardiovascular emergencies such as acute myocardial infarction and unstable angina.

[0003] However, after coronary artery intervention, especially when the surgical puncture point is located in the forearm, some patients may experience local bleeding or blood exudation, resulting in forearm hematoma formation. This situation not only affects the patient's recovery process, but may also cause discomfort and even complications. In order to effectively prevent and treat this postoperative hematoma phenomenon, local compression measures are usually required to promote hemostasis and reduce blood exudation.

[0004] In current clinical practice, the commonly used local compression method is to manually bandage the surgical site with gauze combined with an elastic bandage. Although this method is simple and easy to use, it has obvious limitations: first, it is difficult to ensure uniform pressure distribution in the entire compression area during manual bandaging, which may lead to insufficient compression in some key locations and excessive compression in other locations, thus affecting the hemostatic effect; second, long-term compression can easily cause damage to the skin, such as skin damage, blisters, and even infections, which brings additional physical burden and pain to patients.

[0005] Therefore, there is an urgent need for a more precise and safe local compression solution to overcome the defects of existing technologies and better serve the management of patients after coronary artery intervention. Summary of the invention

[0029] The following is combined with Figure 1-5 The present application is further described in detail. An embodiment of the present application discloses a device for compressing forearm hematoma after coronary surgery.

[0030] Reference Figure 1 and Figure 2 As shown, a device for compressing forearm hematoma after coronary surgery includes a plate body 100, a curved plate 200 and a driving assembly 400.

[0031] The plate 100 is extended along the direction in which the patient places his arm, and its main function is to provide stable support for the patient's arm, ensuring that the arm is in a correct and comfortable position when the hematoma is compressed. This design not only improves the convenience of operation, but also enhances the comfort of the patient.

[0032] The arc plates 200 are provided with at least two arc plates 200 which are relatively and slidably mounted on the plate body 100 and can move freely along the width direction of the plate body 100. By adjusting the distance between the arc plates 200, the pressure and range of the patient's arm can be accurately controlled. When the two arc plates 200 are close to each other, they will apply uniform pressure to the patient's arm, thereby effectively preventing the formation of hematoma; when they move away from each other, the pressure can be relieved, which is convenient for medical staff to check or adjust, ensure uniform pressure distribution, and reduce the risk of skin damage. In addition, this design can also be flexibly adjusted according to the specific situation of the patient to meet the needs of different arm diameters.

[0033] The driving assembly 400 is connected to the arc plate 200, and is used to drive the two arc plates 200 to move closer to each other to squeeze the arm or move away from each other. The driving assembly 400 is equipped with a pressure sensor 500, a controller and an alarm, which can monitor and adjust the compression force in real time to ensure that the pressure distribution in the entire compression area is uniform and appropriate, avoiding skin damage or other complications caused by excessive compression.

[0034] The surface of the plate 100 is provided with an air cushion 110, and a highly sensitive pressure sensor 500 is embedded inside the air cushion 110 for real-time detection of the pressure value applied to the patient's arm. The controller and the alarm are fixedly mounted on the plate 100 and are electrically connected to the pressure sensor 500. This design enables the entire system to dynamically monitor and adjust the pressure distribution in the compression area, thereby ensuring uniform pressure in the entire compression area and avoiding insufficient or excessive compression at certain key locations.

[0035] The controller performs intelligent analysis based on the data fed back by the pressure sensor 500. Once it finds that the pressure distribution is uneven or exceeds the preset safety range, it immediately triggers the alarm to sound an alarm. This precise pressure control not only significantly improves the hemostatic effect, but also effectively reduces the risk of skin damage caused by excessive local pressure. In addition, by optimizing the selection of materials and structural design of the air cushion 110, the patient's experience is further improved, allowing them to maintain a high level of comfort during long-term compression.

[0036] By integrating advanced sensing technology and intelligent control systems, precise regulation and real-time monitoring of the pressure in the compression area are achieved, which significantly improves the hemostasis effect and greatly reduces the risk of skin damage. It provides patients with a safer and more comfortable treatment experience, and is particularly suitable for medical scenarios that require long-term compression hemostasis.

[0037] Reference Figure 1 and Figure 2 As shown, each arc plate 200 is designed with an arc concave surface 210 facing the arm, and these arc concave surfaces 210 are arranged relative to each other to ensure that the pressure applied to the arm is evenly distributed and fits the ergonomics, thereby improving the compression accuracy and comfort. Two arc plates 200 form a group, and each group contains two corresponding arc plates 200. In this way, accurate and gentle compression can be achieved on different areas of the forearm.

[0038] In order to further optimize the compression effect and adapt to arms of different lengths, the device is equipped with at least two groups of such arc plates 200. These groups are arranged in sequence along the length direction of the plate body 100 to form multiple compression areas, so as to more comprehensively cover the patient's arm, provide continuous and stable compression, and effectively enhance the compression effect. Each group of arc plates 200 can independently adjust the position and pressure to meet the specific needs of different patients, and flexibly control the compression strength according to actual needs.

[0039] In addition, this multi-stage design not only improves the accuracy of compression, but also reduces the risk of skin damage caused by excessive compression at a single point. Through the segmented compression method, different degrees of pressure adjustment can be achieved in different compression areas, making the entire compression process more scientific and reasonable, which helps to accelerate the patient's recovery process.

[0040] Airbags 300 are installed on the arc-shaped concave surface 210 of the arc-shaped plate 200. These airbags 300 can fit tightly and effectively squeeze the arm to ensure uniform distribution of the pressure. Each airbag 300 is wrapped around multiple arc-shaped plates 200 on the same side along the length direction of the plate body 100, which not only fills the gap between two adjacent arc-shaped plates 200, but also significantly improves the overall continuity and uniformity of the pressure.

[0041] Specifically, the design of the airbag 300 enables it to adaptively adjust its shape under different pressures to perfectly fit the various curvature changes on the arm surface. This design not only avoids the problem of excessive local pressure due to excessive pressure at a single point, but also ensures a more balanced pressure distribution in the entire compression area. In addition, the airbag 300 fills the gap between two adjacent curved plates 200, ensuring seamless transmission of the compression force and further enhancing the consistency and stability of the compression.

[0042] To further enhance the user experience and treatment effect, the airbag 300 is made of highly elastic material, which provides sufficient compression force while having good flexibility and durability. This not only improves the convenience and safety of the device, but also provides patients with a more comfortable wearing experience. The intelligent adjustment function of the airbag 300 can also dynamically adjust the compression intensity according to actual needs to meet the treatment needs of different stages, thereby accelerating the patient's recovery process.

[0043] The curved plate 200 is provided with a receiving chamber 220 for storing cooling liquid. The receiving chamber 220 has an opening at the top of the outer wall of the curved plate 200 and is provided with a sealing cover 230. Medical staff can inject an appropriate amount of cooling liquid into the receiving chamber 220 as needed to adjust the temperature of the compressed part and relieve the patient's discomfort. This design is particularly suitable for long-term compression and helps to relieve the patient's pain and discomfort.

[0044] Reference Figure 2 and Figure 3 As shown, a receiving chamber 220 is provided inside the curved plate 200 for storing cooling liquid. The opening of the receiving chamber 220 is located at the top of the outer wall of the curved plate 200, and is equipped with a sealing cover 230, which is embedded in the opening of the receiving chamber 220. It is ensured that no leakage occurs during use. Medical staff can inject an appropriate amount of cooling liquid into the receiving chamber 220 according to the actual situation of the patient to accurately adjust the temperature of the compressed part and effectively relieve the patient's discomfort.

[0045] Reference Figure 3 and Figure 4 As shown, this design is suitable for situations where long-term compression is required. Through the effect of the cooling liquid, the patient's pain and discomfort can be significantly reduced. In addition, the presence of the cooling liquid can also help reduce the temperature of the local tissue, thereby reducing the risk of skin inflammation or damage caused by long-term compression. In order to further optimize the cooling effect, the interior of the accommodating cavity 220 adopts a U-shaped inner cavity, so that the cooling liquid can be evenly distributed in the cavity, ensuring that the temperature regulation of the entire compression area is more balanced and consistent.

[0046] Reference Figure 4 and Figure 5 As shown, the driving assembly 400 includes a motor 410 and a driving member. The driving member is fixedly mounted on the side wall of the plate body 100 in the width direction, and the motor 410 is fixedly mounted on the driving member. The motor 410 can move up and down along the height direction of the plate body 100 under the drive of the driving member.

[0047] The driving assembly 400 further includes a threaded shaft 440, a transmission screw 450, and a push block 460 corresponding to each arc plate 200. A transmission cavity 130 is provided on the bottom surface of the plate body 100 along its length direction, and a slide groove 140 is provided on the side opposite to the driving member, and a slider 480 is provided in the slide groove 140 to move along the height direction of the plate body 100. In this way, the smoothness of movement is ensured during the process of adjusting the position of the motor 410. One end of the threaded shaft 440 is coaxially fixedly connected to the output shaft of the motor 410, and is extended along the length direction of the plate body 100 and arranged in the transmission cavity 130, and the other end is rotatably arranged on the slider 480, thereby ensuring the stable rotation of the threaded shaft 440.

[0048] The plate body 100 is provided with driving chambers corresponding to the number of each group of arc plates 200. These driving chambers are arranged along the width direction of the plate body 100 and vertically connected to the transmission chamber 130. The transmission screw 450 is rotatably arranged in the transmission chamber 130, and both ends are rotatably fixed on the plate body 100. The transmission screw 450 and the threaded shaft 440 are respectively provided with helical gears 470 for mutual engagement. The motor 410 is used as a power source, and the transmission screw 450 is driven to rotate through the threaded shaft 440.

[0049] The plate body 100 is provided with a plurality of through slots 120 corresponding to each arc plate 200 in the thickness direction, and these through slots 120 are arranged along the length direction of the driving screw 450. The pushing block 460 is slidably arranged in the through slot 120, and is fixedly connected to the outer wall of the arc plate 200 at one end, and the other end extends out of the through slot 120 and is connected to the driving screw 450 through a thread. In particular, the threads at both ends of the driving screw 450 are arranged to rotate in opposite directions, so that the pushing blocks 460 can be synchronously moved closer to or farther from each other during the rotation of the threaded shaft 440, thereby achieving effective squeezing of the patient's arm.

[0050] The driving member includes an electric slide bar 420 and an electric slider 430. The electric slide bar 420 is fixed to one side of the plate body 100, the electric slider 430 is mounted on the electric slide bar 420, and the motor 410 is fixedly mounted on the electric slider 430. When the electric slider 430 starts to move up and down along the electric slide bar 420, the bevel gear 470 can be engaged or disengaged, thereby adjusting the position of different push blocks 460 in the width direction of the plate body 100. In addition, the threaded shaft 440 is located above the transmission screw 450. This layout optimizes space utilization and improves the compactness of the overall structure.

[0051] How to use An appropriate combination of the plate body 100 and the curved plate 200 is selected according to the patient's arm size.

[0052] The arm is placed on the air cushion 110 of the plate body 100, and the arc plate 200 is adjusted so that its arc-shaped concave surface 210 fits the shape of the arm.

[0053] The drive assembly 400 is activated to bring the curved plate 200 closer and gently squeeze the arm, while monitoring the pressure value to ensure even distribution.

[0054] Adjust the amount of coolant as needed to maintain appropriate compression temperature and improve comfort.

[0055] After the predetermined time has elapsed, slowly release the pressure and remove the device to complete the operation.

[0056] In summary, the present invention achieves effective compression of arm hematoma through careful design of the plate body 100, the curved plate 200 and the drive assembly 400, while taking into account personalized needs and patient comfort, providing a more efficient and safe solution, which is of great significance for improving the quality of care after coronary surgery.

[0057] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
