Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a device for continuous compression hemostasis after femoral artery intervention. Background Technology

[0002] Transfemoral artery intervention is a commonly used minimally invasive procedure for the clinical treatment of cardiovascular and peripheral vascular diseases. Postoperative continuous and effective compression hemostasis at the puncture site is a key step in preventing complications such as bleeding and hematoma, and is directly related to the patient's postoperative recovery progress and treatment safety. Therefore, there is an urgent clinical need for the adaptability, stability and ease of operation of postoperative hemostasis devices.

[0003] According to the study "Effectiveness of hemostasis devices for femoral artery after cardiac catheterization" (Furtado, R., Girardi, P., & Costa, R., 2012), "the fixed position of traditional femoral artery hemostasis devices is difficult to adjust individually according to the anatomical differences of different patients, and the compression point is prone to deviating from the puncture site, resulting in unstable hemostasis." The study also pointed out that "during prolonged use, the device is prone to problems of insufficient or excessive compression, which not only affects the hemostasis efficiency but may also cause local tissue damage or the risk of rebleeding." Therefore, the fundamental flaw of existing femoral artery compression hemostasis devices lies in their limited range of adjustment of the compression point, making it impossible to flexibly adjust to different patient body types, and the lack of precise control over the compression force and angle. This leads to the dual problems of unstable hemostasis and poor patient comfort. Therefore, it is necessary to propose a device for continuous compression hemostasis after femoral artery intervention. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a device for continuous compression hemostasis after femoral artery intervention. The device adjusts the position of the restraint band via a displacement component, thereby flexibly adjusting the compression point for different patients and applying continuous compression hemostasis to the puncture site via the restraint band.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A device for continuous compression hemostasis after femoral artery intervention includes a support plate. The top of the support plate is provided with a constraint component for initially applying pressure to the puncture site. The top of the support plate is provided with a displacement component for adjusting the position of the constraint component. The constraint component includes several fixing buckles and constraint straps. The fixing buckles are all rotatably engaged with the displacement component. One end of each constraint strap is detachably connected to its adjacent fixing buckle. The other end of the constraint strap and another constraint strap cooperating with it are provided with a tensioning component for controlling the tightness of the constraint strap. The top of the tensioning component is provided with a compression component for applying pressure to the puncture point.

[0006] The technical principles of the above solution are as follows: After placing the patient's buttocks and legs on the support board, straighten the restraint straps and adjust the angle so that the tensioning component is aligned with the patient's puncture site. Use the displacement component to adjust the position of the fixing buckle, further tighten the restraint straps, and fix them to the adjacent fixing buckle to apply initial pressure to the patient's puncture site. Then, use the tensioning component to adjust the tightness of the restraint straps to further strengthen the pressure. Through the pressure component, precise pressure can be applied to the puncture point to enhance the pressure effect.

[0007] The above approach has the following beneficial effects: 1. This invention uses a displacement component to move the fixing buckle, and with the adjustable angle of the restraint strap, it can adapt to the differences in the body shape of different patients' buttocks and legs, and quickly adjust the pressure point to the puncture site, solving the problem of easy displacement of the pressure point in existing devices and improving the targeted hemostasis of pressure.

[0008] 2. By setting up a tensioning component and a compression component, the present invention further enhances the compression effect on the puncture site and achieves precise compression of the compression point.

[0009] 3. In this solution, the restraint straps and fixing buckles are detachably connected, and the displacement components allow for convenient adjustment. The operation is simple and efficient, improving the convenience of clinical use.

[0010] Furthermore, the displacement assembly includes several pins and several grooves on the top of the support plate. Several sliders are slidably fitted in each groove. The top of each slider is rotatably fitted with its adjacent fixing buckle. Fixing holes are opened on the side walls of each slider. Several positioning holes are opened on the outer side walls of each groove. The fixing holes are connected to their adjacent positioning holes. The pins are detachably connected to their adjacent positioning holes and fixing holes.

[0011] Beneficial effects: The sliding cooperation between the slider and the groove enables flexible displacement of the fixed buckle along the support plate. The positioning hole corresponds to the fixing hole and is locked with the pin, which can quickly fix the position of the restraint belt. The adjustment operation is simple and can effectively adapt to the differences in the body shape of different patients' buttocks and legs, ensuring that the pressure point is always aligned with the puncture site and avoiding displacement deviation from affecting the hemostasis effect.

[0012] Furthermore, the tensioning assembly includes a cylindrical gear and several adjusting boxes. Several racks are slidably fitted on the inner sidewalls of the adjusting boxes. One end of each rack is fixedly connected to the end of its adjacent constraint band away from the fixed buckle. The cylindrical gear passes vertically through all the adjusting boxes and rotates with them. All the racks mesh with the cylindrical gear.

[0013] Beneficial effects: The cylindrical gear meshes with several racks, enabling simultaneous tension adjustment of multiple restraint straps with a single rotation, eliminating the need for separate operation and significantly improving adjustment efficiency; at the same time, synchronous adjustment ensures uniform tension of the restraint straps, avoiding pressure shift caused by unbalanced force on one side, stabilizing the force at the puncture site, and enhancing the continuous pressure effect.

[0014] Furthermore, the compression assembly includes a compression seat fixedly connected to the top of the uppermost adjustment box. The top of the compression seat has a through hole, the top of the cylindrical gear extends into the through hole and rotates with it, the top of the cylindrical gear is fixedly connected to a compression screw, the compression screw is threaded into the through hole, and the bottom of the cylindrical gear is rotatably engaged with a compression disc.

[0015] Beneficial effects: The threaded engagement between the compression screw and the through hole converts the rotational motion into the vertical lifting and lowering of the compression disc, achieving precise pressure application to the puncture site with strong pressure controllability; at the same time, the cylindrical gear moves synchronously with the compression screw, and the linkage rack further tightens the restraint band, allowing the compression force and restraint force to work together to improve the stability and reliability of compression hemostasis.

[0016] Furthermore, a strap is fixedly connected to the top of the tray, and a buckle is detachably connected to the other end of the strap, which is fixedly connected to the side wall of the tray.

[0017] Beneficial effects: The straps fit the tray tightly against the patient's body, effectively reducing the risk of device displacement caused by slight patient movements, providing a more stable foundation for continuous pressure at the puncture site, and ensuring the continuity of the hemostasis process.

[0018] Furthermore, the top of the restraint strap is fixedly connected with a female Velcro fastener and a female Velcro fastener.

[0019] Beneficial effects: The Velcro connection method is convenient to operate, and the restraint strap and the fastener can be quickly connected and disconnected without the need for a complicated locking structure. Moreover, the fitting length can be flexibly adjusted, and the restraint strap length can be adjusted according to the pressure requirements.

[0020] Furthermore, the top of the strap is fixedly connected with a female Velcro strap and a female Velcro strap.

[0021] Beneficial effects: Velcro has the characteristics of quick application and removal, adapts to different patients' waist sizes, and requires no additional tools for adjustment, making it efficient and convenient to operate.

[0022] Furthermore, a rubber pad is fixedly connected to the inner bottom wall of the tray.

[0023] Beneficial effects: The rubber pad has good anti-slip properties, which can increase the contact friction between the support plate and the patient's buttocks and legs, effectively reducing the slippage of the device during use; at the same time, the flexible material of the rubber pad can buffer the contact pressure between the support plate and the skin, avoid pressure injury caused by prolonged pressure, and improve the patient's wearing comfort.

[0024] Furthermore, a flexible layer is fixedly connected to the bottom of the pressure plate.

[0025] Beneficial effects: The flexible layer applies pressure directly to the puncture site, which can buffer the rigid pressure of the compression disc and avoid mechanical damage to the skin caused by rigid contact. At the same time, the flexible layer can deform slightly with the pressure, increasing the contact area with the patient, making the pressure evenly distributed, and improving the patient's safety and comfort.

[0026] Furthermore, a knob is fixedly connected to the top of the compression screw.

[0027] Beneficial effects: The knob provides a convenient point of force application for the compression screw. Compared with directly turning the screw, it is easier to operate and allows medical staff to quickly adjust the compression force. At the same time, it avoids slippage during the turning process and ensures that the lifting range of the compression screw is precise and controllable, thereby achieving fine adjustment of the compression force.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following detailed description illustrates the specific implementation method: Example 1:

[0037] As attached Figure 1 As shown: A device for continuous compression hemostasis after femoral artery intervention includes a support plate 1. The top of the support plate 1 is provided with a constraint component for initial pressure application to the puncture site, and the top of the support plate 1 is provided with a displacement component for adjusting the position of the constraint component. The constraint component includes several fixing buckles 5 and constraint straps 6. Each fixing buckle 5 is rotatably engaged with the displacement component. One end of each constraint strap 6 is detachably connected to an adjacent fixing buckle 5. The other end of each constraint strap 6 and another constraint strap 6 cooperating with it are provided with a tensioning component for controlling the tightness of the constraint strap 6.

[0038] The displacement assembly includes several pins and several grooves 2 on the top of the support plate 1. Several sliders 3 are slidably fitted in each groove 2. The top of each slider 3 is rotatably fitted with a fixing buckle 5 adjacent to it. Each slider 3 has a fixing hole on its side wall. Each groove 2 has several positioning holes 4 on its outer side wall. The fixing holes are connected to the positioning holes 4 adjacent to them. Each pin is detachably connected to the positioning holes 4 and the fixing holes.

[0039] Specifically, medical staff place the patient's buttocks and legs on the support plate 1, apply dressings to the compressed area, align the tensioning component with the compressed area, then straighten the restraint strap 6 and adjust the angle to keep the tensioning component above the compressed area; the slider 3 drives the fixing buckle 5 to move on the slide groove 2, move the fixing buckle 5 to its adjacent restraint strap 6, connect the restraint strap 6 and the fixing buckle 5, and then insert the pin into the positioning hole 4 and the adjacent fixing hole to complete the initial restraint fixation.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, the tensioning assembly includes a cylindrical gear 13 and several adjusting boxes 7. Several racks 10 are slidably fitted on the inner sidewalls of the adjusting boxes 7. One end of each rack 10 is integrally formed with the end of its adjacent constraint band 6 away from the fixing buckle 5. The cylindrical gear 13 vertically penetrates all the adjusting boxes 7 and rotates with them. All racks 10 mesh with the cylindrical gear 13.

[0041] The top of the tensioning assembly is provided with a pressure assembly for applying pressure to the puncture point. The pressure assembly includes a pressure seat 8 bolted to the top of the uppermost adjustment box 7. The top of the pressure seat 8 has a through hole. The top of the cylindrical gear 13 extends into the through hole and rotates with it. A pressure screw 9 is welded to the top of the cylindrical gear 13. The pressure screw 9 is threaded with the through hole. A pressure disc 12 is rotated with the bottom of the cylindrical gear 13.

[0042] Specifically, after the initial constraint is completed, the pressure screw 9 is screwed into the through hole. At this time, the pressure screw 9 drives the cylindrical gear 13 to move downward. At the same time, the cylindrical gear 13 rotates with the pressure screw 9, thereby driving the rack 10 to move away from the constraint band 6, thereby further tightening the constraint band 6. Meanwhile, the cylindrical gear 13 drives the pressure plate 12 to move downward, thereby applying pressure to the compression area to continuously compress and stop bleeding.

[0043] like Figure 1 As shown, a strap 11 is bolted to the top of the tray 1, and a buckle is detachably connected to the other end of the strap 11. The buckle is bolted to the side wall of the tray 1.

[0044] Specifically, the patient's waist is restrained and fixed using strap 11, and then the strap 11 is fixed to the support plate 1 by buckles, thereby further fixing the support plate 1 to the patient.

[0045] This device integrates constraint compression, position adjustment, and precise pressure application functions, enabling the entire process from initial constraint compression to continuous hemostasis directly after femoral artery intervention, simplifying clinical procedures and achieving continuous pressure at the puncture site. Through the coordinated operation of the displacement, tensioning, and compression components, the device allows for flexible adjustment of the constraint band 6 position, simultaneous tightening, and pressure application to the compression disc 12, reducing the workload of medical staff while preventing compression point displacement and excessive pressure, thus improving the safety and reliability of postoperative hemostasis.

[0046] Example 2:

[0047] As attached Figure 1 As shown, the difference from Embodiment 1 is that the top of the restraint strap 6 is glued with a hook and loop fastener and a hook and loop fastener. The top of the strap 11 is glued with a hook and loop fastener and a hook and loop fastener. A rubber pad is glued to the inner bottom wall of the tray 1. A flexible layer is glued to the bottom of the pressure plate 12. A knob is integrally formed on the top of the pressure screw 9.

[0048] Specifically, the end of the restraint strap 6 furthest from the rack 10 is passed through the retaining buckle 5, then rotated around the retaining buckle 5 to attach the Velcro liner and the Velcro tab, thus quickly connecting the restraint strap 6 to the retaining buckle 5; the end of the bandage 11 furthest from the support plate 1 is passed through the buckle, then rotated around the buckle to attach the Velcro liner and the Velcro tab, thus quickly connecting the bandage 11 to the buckle; the rubber pad contacts the patient's buttocks and legs to increase friction and further enhance the fixation effect. Pressure is applied to the compression area through the flexible layer, avoiding mechanical damage caused by direct pressure from rigid objects. Rotating the knob rotates the compression screw 9, reducing slippage.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
