Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a pressure-sensitive self-adjusting femoral artery compressor. Background Technology

[0002] Femoral artery puncture is a commonly used method to establish vascular access in the treatment of intracranial arterial or venous system diseases (such as acute ischemic stroke due to large vessel occlusion, venous sinus stenosis, and venous sinus thrombosis), for cerebral angiography and endovascular treatments (such as balloon angioplasty or stent placement). To ensure smooth instrument passage, a larger diameter femoral artery sheath (such as an 8F sheath) is often used, but this also increases the risk of vascular injury. Therefore, rapid removal of the puncture needle and effective hemostasis are crucial to prevent complications such as local infection, bleeding, and thrombosis.

[0003] If hemostasis is ineffective, it can lead to serious consequences such as skin bruising, hematoma, pseudoaneurysm, anemia, or even shock, threatening life. Although devices such as femoral artery occluders and suture devices are available on the market, these tools still have a certain failure rate and cannot guarantee complete hemostasis. Postoperative local compression is necessary, but insufficient pressure or too short a duration may lead to rebleeding; conversely, excessive pressure or too long a duration may cause lower limb ischemia, tissue compression damage, and lower limb edema.

[0004] Some patients who have undergone treatment for large-area cerebral infarction may experience a reduction in lower limb edema after using medications such as albumin and mannitol, or after receiving lower limb muscle massage intervention. At this time, traditional compression methods may increase the risk of rebleeding due to the reduced pressure.

[0005] There are currently two main methods for femoral artery compression: one is manual compression combined with pressure bandages or heavy objects such as saline bags for continuous compression, which relies on medical staff and is difficult to maintain constant pressure; the other is an automatic compression device, which can provide stable pressure, but it is difficult to adjust the pressure in real time to adapt to changes in leg swelling or reduction, which may affect the effect and cause discomfort.

[0006] This invention designs a pressure-sensitive adaptive femoral artery compressor that can dynamically adjust the compression force by monitoring the swelling status of the lower limb in real time, thereby reducing the risk of postoperative bleeding, alleviating the burden on medical staff, and improving the safety of vascular interventional therapy. Utility Model Content

[0007] The purpose of this invention is to provide a pressure-sensitive self-adjusting femoral artery compressor, which solves the technical problem that existing femoral artery compressors cannot adaptively adjust the compression force according to changes in leg swelling or reduction.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a pressure-sensitive self-adjusting femoral artery compressor, comprising:

[0009] The compression belt has a locking mechanism at one end and a rack at the other end, with a compression rod running through its surface. The contact surface of the compression rod is equipped with a sensing pad, which is used to detect the pressure on the contact surface of the compression rod. The locking mechanism works with the rack to adjust the pressure on the contact surface of the compression rod.

[0010] The airbag strip, placed inside the compression belt, consists of multiple airbags, and each airbag is equipped with a three-way connector; each three-way connector has an air inlet, an air outlet, and an air outlet, the air outlet is connected to the airbag, and the air outlet is connected to the outside.

[0011] The inflation strip has an inflation valve at one end and extends to connect to multiple air inlets in each airbag at the other end. The inflation strip inflates multiple airbags with equal amounts of air, and the three-way connector expels air through the exhaust port to reduce pressure on certain swollen areas of the patient. At the same time, the locking mechanism, in cooperation with the rack, ensures that the pressure on the contact surface of the compression rod remains at a constant standard.

[0012] Furthermore, the locking mechanism includes:

[0013] The ratchet, which meshes with the rack, is used to manually lock or unlock the two ends of the compression belt;

[0014] An electric gear, meshing with a rack, is used to increase or decrease the relative distance between the two ends of the compression belt;

[0015] The controller's output is electrically connected to the electrical control input of the electric gear, and its input is also equipped with a Bluetooth transmission module. The Bluetooth transmission module and the sensing pad have a Bluetooth transmission channel. After receiving the pressure information from the sensing pad, the controller adjusts the rotation of the electric gear according to the preset constant pressure value, so that the relative distance between the two ends of the compression belt increases or decreases. At the same time, when the two ends of the compression belt are manually locked or manually opened, the controller controls the electric gear to idle.

[0016] Furthermore, the sensor pad adheres to the contact surface of the pressure rod.

[0017] Furthermore, the three-way interface can be set inside the airbag. The air inlet and air outlet of the three-way interface are set parallel to each other. A rotatable ball valve is provided inside the three-way interface. The ball valve has a first passage and a second passage. The first passage is parallel to the air inlet and air outlet. The second passage is an L-shaped passage, one end of which is connected to the air outlet.

[0018] Furthermore, all the airbags are tightly connected.

[0019] Furthermore, the outer surface of the tee connector has clear markings.

[0020] This invention proposes a pressure-sensitive self-adjusting femoral artery compressor, which has the following significant advantages compared to existing manual and automatic compressors:

[0021] Intelligent adjustment: By integrating sensor pads and a controller, intelligent monitoring and adjustment of the compression force are achieved. When the pressure on the contact surface of the compression rod changes, the sensor pads send the data to the controller via Bluetooth transmission module. The controller adjusts the working state of the electric gears according to the preset constant pressure value, automatically adjusting the tension of the compression belt to ensure that the compression force is always within the optimal range.

[0022] Enhanced comfort and safety: This compression device features an airbag strip containing multiple air pockets. The air pressure within each pocket can be adjusted via the inlet, outlet, and exhaust ports of the three-way connector to regulate the pressure according to the patient's leg swelling, preventing lower limb ischemia or compression injury caused by improper compression. Furthermore, the three-way connector incorporates a rotatable ball valve, allowing for flexible adjustment of airflow direction to ensure even pressure distribution and improve patient comfort.

[0023] Easy to operate: The locking mechanisms at both ends of the compression belt support both manual and electric adjustment, simplifying the operation process. In emergencies, medical staff can quickly adjust the compression intensity by manually locking or unlocking the ratchet, while under normal circumstances, the adjustment can be completed automatically using the electric gears and controller, reducing the workload of medical staff and allowing them to better focus on other medical tasks.

[0024] Highly adaptable: This device is not only suitable for patients of different body types, but can also adapt to changes in leg swelling or reduction caused by various reasons after surgery. It ensures the consistency and reliability of the compression effect by automatically adjusting the compression force, reducing the risk of rebleeding.

[0025] In summary, the pressure-sensitive self-adjusting femoral artery compressor provided by this utility model not only improves the safety and reliability of hemostasis, but also greatly improves patient comfort and reduces the operational difficulty for medical staff, thus having significant clinical application value.

Detailed Implementation

[0031] Currently, commonly used hemostatic methods in clinical practice mainly include manual compression combined with pressure bandages or continuous compression using heavy objects such as saline bags, and automatic compression devices. The former requires skilled operation from medical personnel and is difficult to maintain constant pressure, while the latter, although providing stable pressure, is difficult to adjust in real time according to the swelling or subsidence of the patient's leg. Both methods have certain limitations, especially in patients who have used albumin, mannitol, or received lower limb muscle massage to prevent deep vein thrombosis; the effectiveness of traditional compression methods can be affected by changes in lower limb edema.

[0032] In view of the above problems, this utility model provides a pressure-sensitive self-adjusting femoral artery compressor, aiming to solve the shortcomings of the existing technology through intelligent means. Figures 1-3 As shown, the device mainly includes several important components such as a compression belt 200, an airbag strip 400, an inflation strip, and a locking mechanism 210.

[0033] The compression belt 200 has a locking mechanism 210 at one end and a rack 220 at the other end. A compression rod 100 runs through the surface of the belt, and a sensing pad 110 is provided on the contact surface of the compression rod 100 to detect the magnitude of the compression force. The locking mechanism 210 works in conjunction with the rack 220 to manually adjust the pressure on the contact surface of the compression rod 100. The locking mechanism 210 includes a ratchet, an electric gear, and a controller. The controller receives the pressure information from the sensing pad 110 via a Bluetooth transmission module and adjusts the working state of the electric gear according to the preset pressure value, thereby automatically adjusting the tension of the compression belt 200.

[0034] The airbag strip 400 is located inside the compression band 200 and consists of multiple tightly connected airbags 500. Each airbag 500 has a three-way connector 300 with an air inlet 330, an air outlet 320, and an air vent 310. One end of the airbag strip has an inflation valve 600, and the other end is connected to the air inlet 330 of each airbag 500, allowing equal amounts of air to be inflated into the multiple airbags 500. The three-way connector 300 can expel air through the air vent 310 to reduce pressure on certain swollen areas of the patient. At the same time, the locking mechanism 210, in cooperation with the rack 220, ensures that the pressure on the contact surface of the compression rod 100 remains constant.

[0035] The three-way connector 300 features a rotatable ball valve design inside, which can flexibly adjust the airflow direction to ensure uniform pressure distribution and improve patient comfort. Each three-way connector 300 has a clearly marked outer surface for easy identification by medical personnel during operation.

[0036] The pressure-sensitive self-adjusting femoral artery compress sleeve of this utility model has the following significant functional features:

[0037] Intelligent adjustment: By integrating the sensing pad 110 and the controller, intelligent monitoring and adjustment of the compression force are achieved. When the pressure on the contact surface of the compression rod 100 changes, the sensing pad 110 sends the data to the controller via Bluetooth transmission module. The controller adjusts the working state of the electric gear according to the preset constant pressure value, automatically adjusting the tension of the compression belt 200, thereby ensuring that the compression force is always within the optimal range.

[0038] Enhanced comfort and safety: The compressor is designed with an airbag strip 400 containing multiple airbags 500. The air pressure in each airbag 500 can be adjusted according to the different swelling of the patient's leg through the air inlet 330, air outlet 320 and air outlet 310 of the three-way interface 300, so as to avoid problems such as lower limb ischemia or compression injury caused by improper compression.

[0039] Easy to operate: The locking mechanisms 210 at both ends of the compression belt 200 support both manual and electric adjustment, simplifying the operation process. In emergencies, medical staff can quickly adjust the compression intensity by manually locking or unlocking the ratchet, while under normal circumstances, the adjustment can be completed automatically using the electric gears and controller, reducing the workload of medical staff and allowing them to better focus on other medical tasks.

[0040] Highly adaptable: This device is not only suitable for patients of different body types, but can also adapt to changes in leg swelling or reduction caused by various reasons after surgery. It ensures the consistency and reliability of the compression effect by automatically adjusting the compression force, reducing the risk of rebleeding.

[0041] In summary, the pressure-sensitive self-adjusting femoral artery compressor sleeve provided by this invention not only improves the safety and reliability of hemostasis but also greatly enhances patient comfort and reduces the operational difficulty for medical staff, demonstrating significant clinical application value. With technological advancements and increasing medical demands, the application scope of such devices will further expand, and they are expected to become an indispensable part of future clinical practice.
