Description

Technical Field

[0001] The present invention belongs to the technical field of femoral artery puncture site compression after cerebrovascular surgery, and specifically relates to an adjustable compression device for the femoral artery puncture site after cerebrovascular intervention. Background Technique

[0002] Cerebrovascular intervention is an important method for treating cerebrovascular diseases. It delivers instruments such as catheters to the cerebrovascular lesion site through blood vessel accesses such as the femoral artery for diagnosis and treatment. With the development of medical technology, the application of cerebrovascular intervention is becoming more and more extensive. After the operation, the hemostasis treatment of the femoral artery puncture site is a key link. Because the femoral artery is a major artery in the human body, if the puncture wound is not properly treated, it may lead to complications such as bleeding and hematoma. At present, many compression devices for the femoral artery puncture site after cerebrovascular intervention have deficiencies in adjusting the compression range. The tissues around the femoral artery puncture point require an appropriate compression range to ensure the hemostasis effect. However, traditional compression devices often only have a pressing head or pressing area of a fixed size and cannot be flexibly adjusted according to factors such as the size of the puncture wound and the patient's body type. At the same time, because the femoral artery is located at the root of the human thigh, there are rich muscle tissues, adipose tissues and nerves around it, and the compression device is prone to displacement during the patient's movement, affecting the hemostasis effect. Therefore, in view of the above-mentioned problems in the prior art, the present solution proposes an adjustable compression device for the femoral artery puncture site after cerebrovascular intervention. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention designs an adjustable compression device for the femoral artery puncture site after cerebrovascular intervention. By respectively setting a leg fixing band and an abdominal fixing band, both ends of the compression device are fixed to the patient's leg and abdomen respectively, which can improve the stability of fixation and prevent the device from sliding during the patient's movement. At the same time, an adjustment mechanism is provided at the lower end of the pressing block. The pressing area is adjusted according to the pressing part through the limit racks arranged in a four-sided array, improving the accuracy of pressing. And the pressing block and the pressing plate are connected by a lifting screw rod, and the pressing pressure can be adjusted according to needs, improving the hemostasis effect. To achieve the above technical effects, the present invention is realized through the following technical solutions: An adjustable compression device for the femoral artery puncture site after cerebrovascular intervention, comprising: a fixing plate, a telescopic plate, and a pressing block. The front end of the fixing plate is slidably connected to the telescopic plate, and the lower end is movably connected to the pressing block.

[0004] The beneficial effects of the present invention are: By respectively arranging the leg fixing belt and the abdominal fixing belt, the two ends of the pressing device are respectively fixed on the patient's leg and abdomen. When facing actions such as the patient turning over, sitting up, and flexing and extending the legs, it can effectively prevent the device from sliding, ensure that the pressing device is always stably located at the femoral artery puncture site, guarantee the hemostasis effect, and reduce the risk of complications such as bleeding and hematoma caused by device displacement; At the same time, by arranging an adjustment mechanism at the lower end of the pressing block, using the limiting racks arranged in a column on the four sides, according to the actual situation of the pressing part, such as different body types such as the size of the puncture wound, the patient being obese or thin, and having different requirements for the pressing range, the pressing area can be flexibly adjusted, so that the device can adapt to the individual differences of different patients and the specific situation after puncture, making the pressing more targeted, thereby improving the accuracy of pressing and further optimizing the hemostasis effect; and by connecting the pressing block and the pressing plate with a lifting screw rod, the pressing pressure can be conveniently adjusted according to the actual clinical needs, and an appropriate pressing pressure can be accurately provided for each patient, avoiding problems such as excessive pressure affecting local blood circulation or insufficient pressure being unable to effectively stop bleeding, and better guaranteeing the hemostasis effect and the patient's postoperative recovery.

[0008] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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

[0009] As Figures 1-5 shown, the front end of the fixing plate 3 is slidably connected to the telescopic plate 6, and the lower end is movably connected to the pressing block 8; the upper end of the pressing block 8 is provided with a lifting chute 9 slidably connected to the fixing plate 3, a hole is formed in the middle for threadedly connecting the lifting screw 10, and gear chambers 801, connecting rod chambers 802, and worm gear chambers 803 are respectively arranged in the middle of the lower end, and a penetrating rack chute 804 is arranged in the horizontal and vertical directions to movably connect the adjustment mechanism, and a pressing airbag 13 is arranged at the bottom; the lower end of the lifting screw 10 is rotatably connected to the fixing plate 3, and the upper end is provided with a lifting knob 11; the rack chute 804 is arranged up and down in the horizontal and vertical directions; The adjustment mechanism includes a worm 805, an adjustment rod 806, an extrusion knob 807, a limiting plate 808, a limiting rack 809, an adjustment gear 810, a coaxial connecting rod 811, and an adjustment worm gear 812; four limiting racks 809 are integrally arranged on the four sides of the lower end of the pressing block 8 to jointly engage the adjustment gear 810; the limiting rack 809 is fixedly connected to the limiting plate 808 on the outside; the adjustment gear 810 is rotatably connected to the gear chamber 801, and a coaxial connecting rod 811 is arranged at the upper end and rotatably connected to the connecting rod chamber 802; the coaxial connecting rod 811 is provided with an adjustment worm gear 812 at the upper end and rotatably connected to the worm gear chamber 803; a worm 805 is arranged on one side of the adjustment worm gear 812 for meshing; the front end of the worm 805 is fixedly connected to the adjustment rod 806; the adjustment rod 806 penetrates through the pressing block 8 and is provided with an extrusion knob 807; the lower ends of the four sides of the limiting plate 808 are horizontal and higher than the pressing airbag 13; a connecting plate 2 is arranged at the front end of the fixing plate 3 and fixedly connected to the support piece 1, the two sides are movably connected to the leg fixing belt 4, and the rear end is fixedly connected to the pressing plate 5; the connecting plate 2 is L-shaped; In this embodiment, when the device is in use, by surrounding the leg fixing belts 4 on both sides of the front end of the fixing plate 3 around the lower part of the patient's thigh, the fixing plate 3 can be stably located in the corresponding area approximately above the femoral artery puncture site. The leg fixing belt 4 is made of a soft and elastic material with a certain frictional force, and its inner side is provided with a silica gel anti-slip strip to enhance the adhesion and stability with the skin; at the same time, the abdominal fixing belt 7 at the rear end is bypassed around the patient's abdomen to ensure that the device is stably fixed on the patient's abdomen; In this embodiment, both the leg fixing belt 4 and the abdominal fixing belt 7 are made of elastic materials, and at the same time, a magic tape or a buckle can be used for connection at their connection points to adjust the fixing tightness. Since the above fixing method is prior art, it will not be elaborated in this solution; In this embodiment, the working principle of the adjustment mechanism is as follows: when it is necessary to expand or reduce the pressing range, the medical staff rotates the extrusion knob 807. The extrusion knob 807 drives the adjustment rod 806 to rotate, and the worm 805 at the front end of the adjustment rod 806 rotates accordingly. Due to the meshing transmission between the worm 805 and the adjustment worm wheel 812, the worm 805 drives the adjustment worm wheel 812 to rotate. Through the connection function of the coaxial connecting rod 811, the adjustment gear 810 also rotates. Since the four limit racks 809 jointly mesh with the adjustment gear 810, as the adjustment gear 810 rotates counterclockwise, the limit racks 809 move outward along the rack chute 804, and the limit plates 808 fixedly connected to the outside of the limit racks 809 also expand outward, thereby expanding the pressing range; After the adjustment is completed, by rotating the lifting knob 11, the lifting screw rod 10 is driven to rotate. Through the threaded connection between the lifting screw rod 10 and the pressing block 8, the lifting chute 9 inside the pressing block 8 is driven to slide downward along the pressing limit groove 12, so as to press the puncture site of the patient; In this embodiment, during the actual use of the device, a pressure sensor can be set at the pressing airbag 13 to measure the pressing force, so that the pressing force can be accurately adjusted according to the puncture situation of the patient; In this embodiment, through the meshing transmission between the limit racks 809 arranged in a four-sided alignment and the adjustment gear 810, the pressing range can be accurately adjusted according to factors such as the size of the femoral artery puncture wound and the patient's body type. Whether it is a small puncture point or a situation where bleeding occurs around and the pressing area needs to be expanded, it can be flexibly handled. The flexible adjustment of the pressing range can accurately cover the area that needs to be pressed, effectively reducing the situation of incomplete hemostasis or excessive compression of the surrounding tissues caused by improper pressing range, and reducing the incidence of bleeding and hematoma at the puncture site; By connecting the pressing block 8 and the pressing plate 5 with the lifting screw rod 10, the pressing pressure can be accurately set according to the individual vascular conditions and coagulation functions of the patient. The operation is convenient and can be adjusted at any time according to the actual situation of the patient during the postoperative recovery process, avoiding complications such as local blood circulation disorders and nerve injuries caused by excessive pressure; At the same time, a double fixation mode combining the leg fixing belt 4 and the abdominal fixing belt 7 is adopted, which fully considers the structural characteristics of the human thigh root and abdomen and the postoperative activity needs of the patient, effectively coping with various movements of the patient such as turning over, sitting up, and leg flexion and extension, and preventing the displacement of the pressing device. Embodiment 2

[0010] Such as Figure 1 、 2As shown in 6, the rear end of the pressing plate 5 is provided with a pressing limit groove 12 for sliding connection with the pressing block 8, a groove is provided inside to slide and connect the telescopic plate 6, and a plurality of limit grooves 603 are arranged in a row on both sides of the groove; holes are symmetrically provided on both sides of the front end of the telescopic plate 6 to set springs 601, and the rear end is movably connected to the abdominal fixing belt 7; the front end of the spring 601 is fixedly connected to the limit rod 602 and movably connected to the limit groove 603; In this embodiment, when the length of the device needs to be adjusted, the telescopic plate 6 is pulled so that the limiting grooves 603 at both ends squeeze the limiting rod 602, thereby compressing the internal spring 601. After adjusting to a suitable position, the limiting rod 602 is pushed back into the limiting groove 603 under the elastic return action of the spring 601 to prevent it from sliding. In this embodiment, the body size of the patient, especially the distance between the abdomen and the thigh, varies from person to person. The telescopic plate 6 can be adjusted in length according to the patient's body shape. For patients with a tall stature and a long distance between the abdomen and the thigh, the telescopic plate 6 can be stretched so that it can smoothly connect the abdominal fixing belt 7 and the fixing plate 3 to ensure that the device can be firmly fixed on the body; and for patients with a short stature, shortening the telescopic plate 6 can avoid the inconvenience of installation or loose fixation caused by the device being too long. During the postoperative recovery process, the patient will perform some physical activities, such as slight turning over, sitting up or leg flexion and extension. The telescopic plate 6 enables the device to be adjusted to a certain extent as the patient's body shape changes. When the patient turns over, the telescopic plate 6 can be retracted and extended accordingly according to the torsion angle and stretching degree of the body to maintain the overall continuity and stability of the device. When the leg is flexed and extended, the telescopic plate 6 can also flexibly adapt to the dynamic changes in the distance between the thigh and the abdomen to prevent the fixation belt from being too tight or the device from shifting.

[0011] In summary, the present invention respectively provides a leg fixing belt 4 and an abdominal fixing belt 7 to fix the two ends of the pressing device on the patient's legs and abdomen, respectively. When the patient turns over, sits up, or flexes and extends the legs, the device can be effectively prevented from sliding, ensuring that the pressing device is always stably located at the femoral artery puncture site, thereby ensuring the hemostatic effect and reducing the risk of complications such as bleeding and hematoma caused by device displacement. Meanwhile, by arranging an adjustment mechanism at the lower end of the pressing block 8 and utilizing the limit racks 809 arranged in a four-sided alignment, according to the actual situation of the pressing part, such as different body types like the size of the puncture wound, whether the patient is obese or emaciated, etc., which have different requirements for the pressing range, the pressing area can be flexibly adjusted, enabling the device to adapt to the individual differences of different patients and the specific situation after puncture, making the pressing more targeted, thereby improving the accuracy of pressing and further optimizing the hemostasis effect; and by connecting the pressing block 8 and the pressing plate 5 with the lifting screw 10, the pressing pressure can be conveniently adjusted according to the actual clinical needs, and an appropriate pressing pressure can be accurately provided for each patient, avoiding problems such as excessive pressure affecting local blood circulation or insufficient pressure being unable to effectively stop bleeding, and better ensuring the hemostasis effect and the postoperative recovery of the patient.
