Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a femoral artery compression hemostasis device after coronary angiography. Background Art

[0002] Coronary angiography, as an effective diagnostic method for coronary artery diseases, is widely used in clinical practice. Effective hemostasis at the femoral artery puncture site after the operation is a key link to ensure the safety of patients and prevent complications.

[0003] The femoral artery puncture site is located in the inguinal region, where the anatomical structure is complex, increasing the difficulty of hemostasis and dressing. In addition, for some patients with abdominal obesity, their subcutaneous fat layer is relatively thick and the femoral artery is relatively deep. Conventional dressing methods at the puncture site and sandbag compression hemostasis means are often ineffective. In clinical practice, the proportion of subcutaneous hematomas in such patients after the operation is relatively high, which not only brings additional pain to the patients, but may also affect wound healing and subsequent rehabilitation progress.

[0004] Traditional femoral artery compression hemostasis methods mainly include manual compression and sandbag compression. Manual compression requires medical staff to continuously press the puncture site for 20 - 30 minutes or even longer. This not only consumes a lot of energy of medical staff, but also easily leads to fatigue due to maintaining the same posture for a long time, affecting the stability of the compression effect. Moreover, during the compression process, it is difficult for medical staff to accurately control the pressure. Excessive pressure may cause local pain, skin damage or even lower limb ischemia in patients, while too little pressure cannot effectively stop bleeding, increasing the bleeding risk.

[0005] Although sandbag compression saves relatively more manpower, the weight of the sandbag is difficult to be adjusted individually. For obese patients or patients with a high bleeding risk, the conventional sandbag weight may not be sufficient to achieve the purpose of effective hemostasis; while for thin patients, an overweight sandbag may cause unnecessary compression damage. In addition, the patient needs to stay in absolute bed during sandbag compression, which brings great inconvenience to the patient, easily causes discomfort such as low back and back pain and restlessness, and also increases the risk of deep vein thrombosis in the patient's lower limbs. In addition, due to the different body types of patients, it is difficult for the sandbag to accurately press on the patient's puncture point, resulting in poor hemostasis and compression effect.

[0006] Therefore, it is of great clinical significance and practical demand to develop a femoral artery compression hemostasis device after coronary angiography that can adjust the compression pressure, has stable fixation and can accurately adjust the compression angle. Summary of the Invention

[0007] To solve the above technical problems, the present invention designs a femoral artery compression hemostasis device after coronary angiography. The device is fixed to the patient's thigh by adjusting the straps, and the adjustability of the straps can adapt to different body types of patients. At the same time, the whole device is pulled by the neck strap to prevent the device from falling downward due to the patient's obesity. To facilitate the precise adjustment of the compression hemostasis point, the device is provided with a slidable adjustment compression component, which can move the hemostatic block to the puncture point. In addition, to meet the needs of different compression angles, a friction bolt is provided inside the compression component of the device. By changing the height difference of the friction bolts on both sides of the compression component, the angle of the compression component relative to the puncture site is changed. At the same time, to adapt to the adjustability of the compression component of the device, draw slots are provided on both sides of the fixed frame, facilitating the sliding setting of the hemostatic cotton in the draw slots. In this way, during the process of the hemostatic block pressing down on the puncture point, no matter what the compression angle is, it can ensure that the hemostatic cotton has sufficient contact with the patient's puncture point.

[0008] To achieve the above technical effects, the present invention discloses a femoral artery compression hemostasis device after coronary angiography, including: a fixed frame, a compression component, hemostatic cotton, a neck strap, and an adjustment strap; the compression component is slidably connected to the fixed frame; the hemostatic cotton is slidably arranged inside the fixed frame; the neck strap is fixedly connected to the fixed frame; the adjustment strap is fixedly connected to both sides of the fixed frame; Further, the main body of the fixed frame is in an X shape; a sliding slot is fixedly arranged at the top of the fixed frame; draw slots are fixedly arranged on both sides of the fixed frame; Further, the compression component includes: a fixed seat, an adjustment knob, a hemostatic block, and a friction bolt; the hemostatic block is rotatably connected to the bottom of the adjustment knob; the friction bolt is threadedly connected to both sides of the fixed seat; Further, sliding rods are fixedly arranged at both ends of the fixed seat; Further, the adjustment knob includes: an anti-slip cap, a screw rod, and a rotating seat; one end of the screw rod is fixedly connected to the anti-slip cap, and the other end of the screw rod is fixedly connected to the rotating seat; Further, a rubber pad is fixedly arranged at the bottom of the friction bolt.

[0009] The beneficial effects of the present invention are: The present invention discloses a femoral artery compression hemostasis device after coronary angiography. First, through the combined design of the adjustment strap and the neck strap, the device can adapt to patients with different body types, especially obese patients. By using the neck strap to assist in fixing and pulling the device, the problem of unstable fixation and large bleeding volume caused by body type differences in traditional compression hemostasis devices is effectively solved.

[0010] Secondly, the compression component of the device adopts a slidable adjustment design, which can accurately move the hemostatic block to the puncture point position to ensure that the compression force acts directly on the target area. At the same time, by adjusting the angle of the compression component through the height difference of the friction bolt, the requirements for different puncture angles are further met, making the device more advantageous in dealing with complex clinical situations, effectively reducing the risk of postoperative bleeding and improving the hemostatic effect.

[0011] Finally, the pull-out groove design provided on both sides of the fixed frame of the device enables the hemostatic cotton to be conveniently slidably arranged therein. Regardless of how the compression angle changes, the hemostatic cotton can always be in full contact with the puncture point, thereby achieving a uniform and stable compression hemostatic effect.

Detailed Embodiments

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0015] The present invention discloses a femoral artery compression hemostasis device after coronary angiography, referring to Figures 1 to 4, the device includes a fixed frame 1, a compression assembly 2, a hemostatic cotton 3, a neck strap 4 and an adjustment strap 5. Among them, the compression assembly 2 is cooperated with the fixed frame 1 in a sliding connection manner, and can move flexibly on the fixed frame 1, so as to achieve precise positioning of the puncture point. The hemostatic cotton 3 is slidably arranged inside the fixed frame 1, which can ensure that the hemostatic cotton 3 is always in close contact with the puncture point during compression, so as to achieve a good hemostatic effect. The neck strap 4 is fixedly connected to the fixed frame 1, and its main function is to prevent the device from falling downward due to differences in patient body types (such as obese patients) by pulling the whole device, so as to ensure the stability of the device during use. The adjustment strap 5 is fixedly connected to both sides of the fixed frame 1 and is used to firmly fix the whole device on the patient's thigh. Its adjustable design can adapt to the leg thicknesses of different patients and ensure the fixing effect of the device.

[0016] Furthermore, the main structure of the fixed frame 1 is designed in an X shape, and this unique shape endows the device with good stability and support. At the top of the fixed frame 1, a sliding groove 101 is fixedly arranged, and the sliding rod 205 of the compression assembly 2 can move freely in the sliding groove 101, so as to achieve precise adjustment of the position of the compression assembly 2. At the same time, draw slots 102 are fixedly arranged on both sides of the fixed frame 1, and the hemostatic cotton 3 is slidably arranged inside the fixed frame 1 through these draw slots 102.

[0017] The compression assembly 2 itself consists of multiple important components, including a fixed seat 201, an adjustment knob 202, a hemostatic block 203 and a friction bolt 204. The hemostatic block 203 is installed at the bottom of the adjustment knob 202 in a rotational connection manner, and this design enables the angle of the hemostatic block 203 to be adjusted flexibly according to needs to adapt to different compression requirements. The friction bolt 204 is threadedly connected to both sides of the fixed seat 201. By adjusting the height difference of the friction bolt 204, the angle of the compression assembly 2 relative to the puncture site can be changed, so as to achieve precise control of the compression angle, further improving the adaptability and hemostatic effect of the device. At the same time, the friction assembly also functions to fix the position of the compression assembly 2.

[0018] Sliding rods 205 are fixedly arranged at both ends of the fixed seat 201, and the sliding rods 205 cooperate with the sliding groove 101 of the fixed frame 1, so that the compression assembly 2 can slide smoothly on the fixed frame 1, so as to achieve precise positioning of the puncture point position. The adjustment knob 202 includes an anti-slip cap 206, a screw rod 207 and a rotating seat 208. One end of the screw rod 207 is fixedly connected to the anti-slip cap 206, and the other end is fixedly connected to the rotating seat 208. Medical staff can adjust the position and angle of the hemostatic block 203 by rotating the anti-slip cap 206, and the operation is simple and easy to master.

[0019] In addition, a rubber pad 209 is fixedly arranged at the bottom of the friction bolt 204. The rubber pad 209 not only increases the friction between the friction bolt 204 and the fixed seat 201, thereby improving the stability of the device, but also plays a certain damping role during the movement of the pressing component 2, preventing the pressing component 2 from swaying left and right, and improving the accuracy of the device during use.

[0020] The working principle and usage process of this device are as follows: The working principle of this device includes: the adjustable design of the strap 5 enables it to adapt to thighs of different thicknesses, while the neck strap 4 holds the whole device through the traction device, preventing the device from falling down due to patient obesity or other factors, thereby providing stable support for subsequent compression hemostasis operations.

[0021] The core component of the device - the pressing component 2 - can move flexibly within the sliding groove 101 of the fixed frame 1 through its unique sliding connection mechanism. This design allows medical staff to accurately move the pressing component 2 to the target area according to the specific position of the puncture point. The hemostatic block 203 of the pressing component 2 is connected to the fixed seat 201 through the adjusting knob 202, and the angle of the hemostatic block 203 can be adjusted by turning the adjusting knob 202, thereby achieving fine control of the pressing angle. This angle adjustment function is crucial for meeting the requirements of different puncture angles, ensuring that the hemostatic block 203 is in full contact with the puncture point and achieving uniform and effective compression hemostasis.

[0022] At the same time, the friction bolts 204 on both sides of the pressing component 2 are threadedly connected to the fixed seat 201, and the adjustment of their height difference can further change the angle of the pressing component 2 relative to the puncture site. This design not only increases the flexibility of pressing angle adjustment, but also enhances the friction between the device and the patient's skin through the rubber pad 209 at the bottom of the friction bolt 204, ensuring that the hemostatic block 203 does not slide during compression, thereby improving the stability and reliability of hemostasis.

[0023] Below the pressing component 2, the hemostatic cotton 3 is slidably arranged in the draw slots 102 on both sides of the fixed frame 1. This design enables the hemostatic cotton 3 to make corresponding adjustments according to the change of the pressing angle and always keep in close contact with the puncture point. The function of the hemostatic cotton 3 is to provide direct pressure on the puncture point during the downward pressing process of the hemostatic block 203, thereby achieving the hemostasis effect. Through the design of the draw slots 102, the replacement and adjustment of the hemostatic cotton 3 are also more convenient, further improving the practicality and operability of the device.

[0024] The usage process of this device is as follows: During use, medical staff first fix the device on the patient's thigh and adjust the tightness of the adjustment strap 5 and the neck strap 4. Subsequently, according to the position of the puncture point, the compression component 2 is moved to accurately align it with the puncture point. By rotating the adjustment knob 202 and adjusting the height difference of the friction bolt 204, medical staff can flexibly control the angle and compression force of the hemostatic block 203 to ensure that the hemostatic cotton 3 is in full contact with the puncture point and applies an appropriate compression force. During the entire compression hemostasis process, the fixing frame 1 of the device serves as a support structure. Through its unique X-shaped design and the cooperation of the sliding groove 101 and the pulling groove 102, it provides a stable platform for the adjustment of the compression component 2 and the setting of the hemostatic cotton 3.
