Abstract
Description
Technical Field
[0001] This invention belongs to the field of hemostasis device technology, and particularly relates to a brachial artery puncture and compression hemostasis device. Background Technology
[0002] With the rapid development of coronary interventional diagnosis and treatment technology, the number of cases of coronary angiography and interventional treatment via the brachial artery approach is increasing. Compared with the traditional femoral and radial artery approaches, the brachial artery approach has advantages such as straight vessel course, high puncture success rate, and early postoperative mobilization, and is especially suitable for patients with small, variant, or abnormal radial arteries or Allen test. However, hemostasis after brachial artery puncture remains an important clinical problem. The brachial artery is located deep, with little surrounding soft tissue and a large vessel diameter. If hemostasis is not performed properly, complications such as bleeding, hematoma, pseudoaneurysm, or even limb ischemia can easily occur, seriously affecting the patient's prognosis and treatment experience.
[0003] However, some problems still exist in the above solutions:
[0004] Currently, the main clinical method for hemostasis at brachial artery puncture sites is the traditional manual compression combined with gauze pressure bandaging. Medical staff need to apply direct pressure to the puncture site with their fingers for 10-20 minutes or more, followed by securing it with gauze and an elastic bandage. This method has several drawbacks: First, the pressure intensity relies entirely on the operator's experience, making it difficult to quantify and prone to insufficient pressure leading to bleeding or excessive pressure causing distal limb ischemia. Second, the compression time is long, resulting in high labor intensity for medical staff, and patients need to maintain arm immobilization for extended periods, leading to poor comfort. Third, the gauze bandage is prone to loosening or displacement, especially when the patient's arm is active or sweating, causing unstable hemostasis and requiring repeated adjustments, increasing the risk of hematoma formation. Fourth, the lack of pressure monitoring and dynamic adjustment mechanisms makes it unable to adapt to changes in the patient's arm circumference or body position, resulting in a high rate of hemostasis failure.
[0005] While existing technologies have developed specialized compression hemostasis devices for the radial artery, such as pneumatic or mechanical radial artery hemostatic devices, most of these devices are designed for the wrist, are small in size, and have a fixed structure. They cannot be directly applied to the anatomical characteristics of the brachial artery in the upper arm. The few compression devices for the brachial artery also use simple bandages with pressure pads or ordinary inflatable cuffs, which also suffer from problems such as cumbersome operation, invisible pressure, inability to apply pressure with minimal effort, and lack of adaptive adjustment function. They cannot effectively resolve the contradiction of excessive or insufficient pressure during patient activity, thus limiting their clinical application. Summary of the Invention

[0009] The labor-saving pressurizing mechanism includes an air chamber, a connecting lever, a first arm, a second arm, and a piston connector. The piston connector is vertically slidably connected to the inner wall of the air chamber. One end of the connecting lever is rotatably connected to the first arm, and the bottom end of the connecting lever is rotatably connected to the second arm. The bottom end of the second arm is fixedly connected to the top end of the connecting lever.
[0010] Preferably, two anti-slip strips are fixedly connected to the outer side of the adhesive ring, and the airbag strip is fixedly connected to the inner side of the adhesive ring.
[0011] Preferably, a delivery pipe is fixedly connected to the outer side of the airbag strip, and a first one-way valve is connected to the middle of the delivery pipe.
[0012] Preferably, the outer side of the delivery pipe is fixedly connected to one end of the pressure reducing chamber, the other end of the reset spring is fixedly connected to a sealing plate, the sealing plate is fixedly connected to the inner side of the pressure reducing chamber, and the middle part of the connecting rod passes through the sealing plate.
[0013] Preferably, one end of the airbag strip is fixedly connected to a connector, and a transmission tube is connected to the inner side of the connector.
[0014] Preferably, one end of the transmission tube is threaded to the bottom end of the air chamber.

[0016] Preferably, a support member is fixedly connected to the middle of the bracket, and the piston connector is vertically slidably connected to the middle of the support member.
[0017] Preferably, a connecting pipe is fixedly connected to the outside of the air chamber.
[0018] Preferably, a second one-way valve is connected to the middle of the connecting pipe.
[0019] Compared with related technologies, the brachial artery puncture and compression hemostasis device provided by the present invention has the following beneficial effects:
[0020] 1. The brachial artery puncture compression hemostasis device of the present invention produces significant beneficial effects by setting up a labor-saving pressurization mechanism and an adaptive fixation mechanism. The labor-saving pressurization mechanism includes an air chamber, a connecting lever, a first arm, a second arm, and a piston connector. It utilizes the lever principle to amplify the force during manual operation. The operator only needs to pull the first arm with a small force, which, through the linkage of the connecting lever and the second arm, drives the piston connector to compress the air in the air chamber to form high-pressure gas. This high-pressure gas is efficiently transmitted to the balloon strip through the delivery pipe, transmission pipe, and connector, causing the balloon strip to expand rapidly and apply uniform pressure to the brachial artery puncture point. Compared with traditional gauze wrapping or pure manual compression, this mechanism significantly reduces the operational intensity of medical staff, avoids fatigue caused by prolonged pressure, and the inflation process is faster and more controllable, ensuring the timeliness and reliability of hemostasis. It is particularly suitable for clinical environments with a large number of postoperative patients or limited medical resources.
[0021] 2. This invention, through the adoption of an adaptive fixation mechanism including an airbag strip, a decompression chamber, a return spring, a connecting rod, a sealing plug, and indicator rings, achieves the beneficial effects of pressure visualization and dynamic adjustment. During pressurization, the operator can directly observe the position changes of the three indicator rings fixedly fitted at one end of the connecting rod, accurately judging whether the pressure inside the airbag strip is sufficient. This avoids the blindness of relying on experience-based estimation in traditional devices and improves the accuracy of compression. When the patient moves their arm, causing an increase in arm circumference and increased pressure from the airbag strip, excess gas automatically enters the decompression chamber, pushing the sealing plug to compress the return spring. The connecting rod moves accordingly, and the position change of the indicator rings indicates the pressure status. At the same time, the return spring stores elastic potential energy to achieve buffering. This mechanism effectively prevents tissue damage or hematoma caused by excessive compression, significantly improving patient comfort and safety. It is suitable for clinical scenarios requiring postoperative activity or for elderly patients.
[0022] 3. This invention features two anti-slip strips fixedly connected to the outer side of the adhesive ring and an airbag strip fixedly connected to the inner side, resulting in a stable fixation and uniform pressure. The anti-slip strips increase the friction between the device and the skin, ensuring that the adhesive ring and airbag strip do not shift even if the patient's arm sweats or moves slightly, guaranteeing that the pressure point is always accurately aligned with the brachial artery puncture site. This avoids the risk of rebleeding caused by the easy loosening of traditional gauze wrapping. The airbag strip directly contacts the puncture point and achieves large-area flexible pressure through inflation, resulting in a more uniform pressure distribution. Compared to hard pressure blocks, it reduces local high-pressure points, lowering the incidence of skin indentations and nerve damage. At the same time, the adhesive ring, as the integral base, has a simple structure, good fit, and is easy to put on and remove quickly, improving clinical operation efficiency and patient acceptance.
[0023] 4. This invention, by setting a first one-way valve and a second one-way valve, located in the middle of the delivery pipe on the airbag strip side and the air chamber side respectively, produces the beneficial effects of reliable air circuit control and pressure maintenance. The first one-way valve ensures that gas enters the airbag strip in one direction, preventing leakage from causing a pressure drop; the second one-way valve ensures that the compressed gas in the air chamber is output in one direction, avoiding backflow that affects the reset of the piston connector. This double one-way valve design makes the entire air circuit system highly airtight and maintains pressure for a long time, reducing the need for repeated pressurization after surgery. At the same time, combined with the buffering function of the decompression chamber, a relatively stable pressure can be maintained even when the patient is active, prolonging the effective hemostasis time and reducing the incidence of complications. This design does not require an external air source or electronic equipment, is low in cost, and highly reliable, making it particularly suitable for promotion and application in primary hospitals and emergency environments.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0033] Example 1
[0034] A preferred embodiment of the brachial artery puncture and compression hemostasis device provided by the present invention is as follows: Figures 1 to 6 As shown: A brachial artery puncture compression hemostasis device includes: an adhesive ring 1, a force-saving pressure mechanism 2 on one side of the adhesive ring 1, and an adaptive fixing mechanism 4 on the outer side of the adhesive ring 1;
[0035] The adaptive fixing mechanism 4 includes an airbag strip 401, a decompression chamber 404, a return spring 405, a connecting rod 408, a sealing plug 410, and an indicator ring 403. The airbag strip 401 has a decompression chamber 404 on its outer side. The inner wall of the decompression chamber 404 is slidably connected to the sealing plug 410. The inner side of the sealing plug 410 is fixedly connected to the connecting rod 408. The inner side of the sealing plug 410 is fixedly connected to the return spring 405. The return spring 405 is sleeved on the outer side of the connecting rod 408. Three indicator rings 403 are fixedly sleeved on one end of the connecting rod 408.
[0036] The labor-saving pressurizing mechanism 2 includes an air chamber 209, a connecting lever 201, a first support arm 205, a second support arm 207, and a piston connector 208. The piston connector 208 is vertically slidably connected to the inner wall of the air chamber 209. One end of the connecting lever 201 is rotatably connected to the first support arm 205, and the bottom end of the connecting lever 201 is rotatably connected to the second support arm 207. The bottom end of the second support arm 207 is fixedly connected to the top end of the connecting lever 201.
[0037] In this embodiment, by manually operating the first arm 205, the connecting lever 201 and the second arm 207 are linked, thereby driving the piston connector 208 to slide vertically in the air chamber 209 to compress air and generate high-pressure gas. This high-pressure gas is transmitted to the airbag strip 401, causing it to expand and apply uniform pressure to the brachial artery puncture point. At the same time, excess gas enters the decompression chamber 404, pushing the sealing plug 410 to compress the reset spring 405. The movement of the connecting rod 408 causes the position of the indicator ring 403 to change, realizing pressure visualization feedback. When the patient's arm movement causes changes in circumference, the reset spring 405 elastically resets and dynamically adjusts the gas distribution to maintain stable pressure.
[0038] In a further preferred embodiment of the present invention, two anti-slip strips 402 are fixedly connected to the outer side of the adhesive ring 1, and an airbag strip 401 is fixedly connected to the inner side of the adhesive ring 1.
[0039] In this embodiment, the anti-slip strip 402 enhances the friction between the adhesive ring 1 and the patient's upper arm skin to prevent the device from sliding and shifting during use, ensuring that the airbag strip 401 is always accurately aligned with the brachial artery puncture point. At the same time, the airbag strip 401 directly contacts the puncture site on its inner side. When the high-pressure gas generated by the labor-saving pressure mechanism 2 enters the airbag strip 401, it causes it to expand flexibly, achieving large-area uniform pressure to promote local vascular closure and blood coagulation, thereby effectively stopping bleeding and reducing the risk of rebleeding caused by the easy loosening of traditional gauze bandages.
[0040] In a further preferred embodiment of the present invention, a delivery pipe 407 is fixedly connected to the outer side of the airbag strip 401, and a first one-way valve is connected to the middle of the delivery pipe 407.
[0041] In this embodiment, the first one-way valve ensures that the high-pressure gas enters the airbag strip 401 in one direction to avoid leakage and pressure drop. When the labor-saving pressurizing mechanism 2 compresses the air chamber 209 to generate gas, the gas is transmitted to the airbag strip 401 in one direction through the delivery pipe 407 to expand and pressurize it. At the same time, the first one-way valve prevents the gas from flowing back and maintains the pressure inside the airbag strip 401 to stabilize, thereby prolonging the effective hemostasis time and improving the reliability of compression.
[0042] In a further preferred embodiment of the present invention, the outer side of the delivery pipe 407 is fixedly connected to one end of the pressure reducing chamber 404, and the other end of the reset spring 405 is fixedly connected to a sealing plate 409. The sealing plate 409 is fixedly connected to the inner side of the pressure reducing chamber 404, and the middle part of the connecting rod 408 passes through the sealing plate 409.
[0043] In this embodiment, the position of the reset spring 405 is fixed by the sealing plate 409 to ensure its elastic action is stable. When excess gas in the airbag strip 401 enters the decompression chamber 404 through the delivery pipe 407 and pushes the sealing plug 410 to slide and compress the reset spring 405, the connecting rod 408 moves through the sealing plate 409 to drive the indicator ring 403 to change and realize pressure monitoring. At the same time, the reset spring 405 stores elastic potential energy. When the pressure is restored, it pushes the sealing plug 410 to reset and pushes back the gas part to maintain dynamic balance.
[0044] In a further preferred embodiment of the present invention, one end of the airbag strip 401 is fixedly connected to a connector 406, and a transmission tube 3 is connected to the inner side of the connector 406.
[0045] In this embodiment, a closed air circuit connection is formed by the connector 406 and the transmission pipe 3. When the high-pressure gas generated by the labor-saving pressurizing mechanism 2 enters the connector 406 through the transmission pipe 3, it is directly transmitted to the inside of the airbag strip 401, causing it to expand rapidly and apply pressure. At the same time, the connector 406 ensures airtightness to prevent leakage, thereby improving gas transmission efficiency and overall pressurization stability.
[0046] In a further preferred embodiment of the present invention, one end of the transmission pipe 3 is threaded to the bottom end of the air chamber 209.
[0047] In this embodiment, the transmission pipe 3 and the air chamber 209 are reliably fixed and disassembled by a threaded connection. When the piston connector 208 compresses the air chamber 209, the high-pressure gas generated is smoothly output to the connector 406 and the air bag strip 401 through the transmission pipe 3 threaded at the bottom of the air chamber 209, ensuring smooth air circuit connection and facilitating device maintenance and disinfection.
[0048] Example 2
[0049] Based on Example 1, a preferred embodiment of the brachial artery puncture and compression hemostasis device provided by the present invention is as follows: Figures 1 to 6 As shown: A bracket 204 is fixedly connected to the outside of the air chamber 209, and the first arm 205 is rotatably connected to the top of the bracket 204.
[0050] In this embodiment, the bracket 204 provides stable support so that the first arm 205 can rotate smoothly. When the operator pulls the first arm 205, it rotates around the top of the bracket 204, which drives the connecting lever 201 to move together, thereby amplifying the input force to drive the second arm 207 and the piston connector 208 to generate high-pressure gas in the high-efficiency compression chamber 209, thus realizing labor-saving pressurization operation.
[0051] In a further preferred embodiment of the present invention, a support member 206 is fixedly connected to the middle part of the bracket 204, and a piston connector 208 is vertically slidably connected to the middle part of the support member 206.
[0052] In this embodiment, the piston connector 208 is guided vertically by the support member 206 to ensure precise movement. When the connecting lever 201 is driven, the piston connector 208 is stably compressed along the support member 206 to prevent displacement that could lead to gas leakage or uneven pressurization, thereby improving the overall reliability and pressure consistency of the device.
[0053] In a further preferred embodiment of the present invention, a connecting pipe 202 is fixedly connected to the outer side of the air chamber 209.
[0054] In this embodiment, compressed gas is output through the delivery pipe 407 outside the air chamber 209. When the piston connector 208 moves downward to compress the air, the high-pressure gas is transmitted unidirectionally to the downstream air path through the delivery pipe 407 and finally enters the air bag strip 401 to achieve pressurization. At the same time, this connection ensures smooth gas flow and improves the pressurization response speed.
[0055] In a further preferred embodiment of the present invention, a second one-way valve 203 is connected to the middle part of the connecting pipe 202.
[0056] In this embodiment, the second one-way valve 203 ensures that the compressed gas in the air chamber 209 is output in one direction to prevent backflow. When the piston connector 208 is compressed, the gas enters the transmission pipe 3 in one direction through the second one-way valve 203 to avoid pressure loss and maintain the efficient pressurization of the air chamber 209. At the same time, it is combined with the first one-way valve to form bidirectional control and improve the sealing and pressure maintenance effect of the entire gas circuit.
[0057] In summary, firstly, the core fixing component of the device is the adhesive ring 1, which serves as the base and is fixed to the brachial artery puncture site on the patient's upper arm. Two anti-slip strips 402 are fixedly connected to the outer side of the adhesive ring 1. These anti-slip strips 402 enhance the friction between the device and the skin, preventing slippage or displacement during use and ensuring the stability of the compression point. The airbag strip 401 is fixedly connected to the inner side of the adhesive ring 1 and directly contacts the puncture site. The airbag strip 401 is designed similarly to a flexible airbag band, which can apply uniform pressure by inflating, promoting local vascular closure and blood coagulation, thereby achieving hemostasis.
[0058] The labor-saving pressurization mechanism 2 is the core module for pressurization of the device. It includes an air chamber 209, a connecting lever 201, a first support arm 205, a second support arm 207, and a piston connector 208. The principle of this mechanism is based on the lever amplification effect and piston compression of gas to achieve efficient inflation under manual operation. Specifically, the first support arm 205 is rotatably connected to the top of the bracket 204, and the bracket 204 is fixedly connected to the outside of the air chamber 209 to provide a stable support point. One end of the connecting lever 201 is rotatably connected to the first support arm 205, and its bottom end is rotatably connected to the second support arm 207. The bottom end of the second support arm 207 is fixedly connected to the top of the connecting lever 201 to form a linkage lever system. The piston connector 208 is vertically slidably connected to the inner wall of the air chamber 209 and is guided by the support member 206.
[0059] In use, the operator manually pulls or presses the first arm 205 to rotate the connecting lever 201. Due to the lever principle, the longer arm of the first arm 205 can amplify the smaller input force and transmit it to the second arm 207 and the piston connector 208. The piston connector 208 moves downward, compressing the air in the air chamber 209 to form high-pressure gas. This gas is output through the delivery pipe 407 fixedly connected to the outside of the air chamber 209. The middle of the delivery pipe 407 is connected to the second one-way valve 203. The second one-way valve 203 ensures that the gas flows in one direction and prevents backflow from causing pressure loss. One end of the delivery pipe 407 is connected to the transmission pipe 3, and one end of the transmission pipe 3 is threaded to the bottom of the air chamber 209 to form a closed air circuit system.
[0060] The high-pressure gas is further transmitted through the transmission pipe 3 to the connector 406, which is fixedly connected to one end of the airbag strip 401. The gas enters the airbag strip 401, causing it to expand and pressurize, applying controllable pressure to the puncture point. The outer side of the airbag strip 401 is fixedly connected to the delivery pipe 407, and the middle of the delivery pipe 407 is connected to the first one-way valve, which also ensures that the gas enters in one direction and avoids leakage. At the same time, the outer side of the delivery pipe 407 is fixedly connected to one end of the decompression chamber 404, which connects the pressurization process with the adaptive fixation mechanism 4.
[0061] The adaptive fixing mechanism 4 is an innovative highlight of the device, including an airbag strip 401, a decompression chamber 404, a return spring 405, a connecting rod 408, a sealing plug 410, and indicator rings 403. This mechanism provides visual pressure feedback on the one hand, and realizes dynamic buffer adjustment on the other. The sealing plug 410 is slidably connected to the inner wall of the decompression chamber 404. The connecting rod 408 and the return spring 405 are fixedly connected to the inner side of the sealing plug 410. The return spring 405 is sleeved on the outer side of the connecting rod 408, and a sealing plate 409 is fixedly connected to its other end. The sealing plate 409 is fixedly connected to the inner side of the decompression chamber 404. The middle part of the connecting rod 408 passes through the sealing plate 409, and three indicator rings 403 are fixedly sleeved on one end. These indicator rings 403 are exposed on the outside of the device for easy observation.
[0062] During pressurization, as the gas generated by the labor-saving pressurization mechanism 2 expands into the airbag strip 401, excess gas can enter the decompression chamber 404 through the delivery pipe 407. At this time, if the pressure is appropriate, the sealing plug 410 remains in its initial position, the return spring 405 is in a balanced state, and the position of the indicator ring 403 remains unchanged. The operator can judge whether the pressure is sufficient by observing the relative position of the indicator ring 403. If the indicator ring 403 moves to a specific area, it indicates that the pressure has reached the hemostasis requirement (usually 20-50 mmHg), and pressurization can be stopped. This provides intuitive mechanical feedback and avoids the drawbacks of traditional devices that rely on experience.
[0063] On the other hand, when the patient moves their arm, the arm circumference may increase, leading to increased pressure on the airbag strip 401 and excessively high internal gas pressure. At this time, excess gas will be further pushed into the decompression chamber 404, causing the sealing plug 410 to slide along the inner wall of the decompression chamber 404, compressing the return spring 405 inward. The connecting rod 408 moves accordingly, and the position of the indicator ring 403 changes, indicating pressure adjustment. Simultaneously, the elastic potential energy of the return spring 405 stores excess pressure, achieving buffering. When the arm circumference returns to normal, the return spring 405 releases its elasticity, pushing the sealing plug 410 and connecting rod 408 back to their original positions, partially pushing the gas back into the airbag strip 401 to maintain stable pressure. This dynamic adjustment mechanism ensures the device's adaptability and reduces the risk of hematoma or discomfort.
[0064] Overall, the device operates as follows: First, the adhesive ring 1 is fixed to the upper arm, and the balloon strip 401 is aligned with the puncture point. Then, through the manual operation of the labor-saving pressurization mechanism 2, the first arm 205 is pulled, which in turn links the second arm 207 and the piston connector 208 to compress the air chamber 209. The generated gas is then injected into the balloon strip 401 through the delivery pipe 407, the transmission pipe 3, and the connector 406 to achieve pressure hemostasis. At the same time, the adaptive fixation mechanism 4 monitors the pressure, observes the indicator ring 403 to determine sufficiency, and performs gas buffering and dynamic adjustment through the cooperation of the decompression chamber 404, the sealing plug 410, the connecting rod 408, and the return spring 405 when the arm moves. The entire process requires no external power supply, is purely mechanical and pneumatic, and is easy to operate. It is suitable for brachial artery compression after clinical coronary intervention surgery. Compared with traditional gauze wrapping, this device provides more uniform and visible pressure, and has strong self-adaptability. In clinical applications, it can significantly reduce the incidence of complications.
