Description

Technical Field

[0001] The invention relates to the technical field of radial artery hemostasis equipment, and in particular to a radial artery compressor after cardiovascular intervention surgery. Background Art

[0002] The conventional access route for PCI is percutaneous puncture of the femoral artery. However, with the miniaturization of cardiac catheter devices, percutaneous puncture of the radial artery has begun to be used at home and abroad. This new puncture method has the advantages of less damage, faster recovery, shorter hospitalization time, and fewer peripheral vascular complications.

[0003] After percutaneous radial artery interventional treatment, the puncture needle needs to be removed. When the puncture needle is removed, the patient's radial artery will bleed. However, since the radial artery is an artery, conventional hemostasis methods cannot be used to stop bleeding. In the prior art, a hemostat specifically for the radial artery is usually used to stop bleeding. In the radial artery hemostasis process, it is necessary to start pressing the wound when the puncture needle is removed. After 6 hours of compression, the pressure needs to be slowly reduced and compressed again. The whole process requires releasing the pressure multiple times to achieve the final hemostasis effect. When using a radial artery hemostat, doctors usually release the pressure manually at a fixed time, which is more labor-intensive. If there are many patients, late operation may occur, thereby causing damage to the patient's bleeding site.

[0004] In order to solve the above problems, a radial artery compressor for post-cardiovascular intervention is proposed. Summary of the invention

[0005] In view of the above problems, the present invention provides a radial artery compressor for post-cardiovascular intervention surgery, which solves the problem that the radial artery is an artery and cannot be stopped by conventional hemostasis methods when it bleeds. In the prior art, a hemostat dedicated to the radial artery is usually used for hemostasis. In the process of radial artery hemostasis, it is necessary to start compressing the wound when the puncture needle is pulled out. After 6 hours of compression, the pressure needs to be slowly reduced and compression is performed again. The whole process requires releasing the pressure multiple times to achieve the final hemostasis effect. When using the radial artery hemostat, doctors usually release the pressure manually at a fixed time, which is more labor-intensive. If there are many patients, late operation may occur, thereby causing damage to the bleeding site of the patient.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] refer to Figures 1 to 12, a radial artery compressor after cardiovascular intervention, comprising a mounting plate 1, a fixed shell 13, a fixed barrel 17, a sliding plate 18, a cleaning roller 24, an expansion shell 101, a fixing buckle 1011, a connecting rod 14, a compression barrel 2, a pressurizing component, a reciprocating mechanism, a driving mechanism, a sliding mechanism, and a driving mechanism; The lower left end of the mounting plate 1 is connected to an expansion shell 101, and a compression barrel 2 is installed in the expansion shell 101 through which the compression barrel 2 is slidably installed. The upper end of the compression barrel 2 is slidably connected with the mounting plate 1, and the compression barrel 2 is driven downward by two pressurizing components. The compression barrel 2 slides downward under the drive of the two pressurizing components to achieve compression and hemostasis of the patient's needle-pierced part; A fixed shell 13 is movably installed in the compression barrel 2, and the fixed shell 13 is connected to the compression barrel 2, so that the air pressure provided by the pressurizing mechanism can enter the fixed shell 13 and the compression barrel 2 at the same time. However, since the fixed shell 13 is fixed by the connecting rod 14 described later, the air pressure will enter the compression barrel 2 through the fixed shell 13, so that the compression barrel 2 is pressed downward; Two pressurizing components are arranged in the fixed shell 13; First connecting shafts 1301 are fixedly installed on both sides of the upper end of the left side wall of the fixed shell 13, and the two first connecting shafts 1301 are movably arranged above the compression barrel 2; The first ends of the connecting rods 14 are respectively fixedly mounted on the outer sides of the two first connecting shafts 1301; Two second connecting shafts cooperating with the first connecting shaft 1301 are installed on the left side wall of the mounting plate 1, and the second ends of the two connecting rods 14 are respectively fixedly sleeved on the outer sides of the two second connecting shafts; A plurality of cleaning rollers 24 are detachably mounted below the compression barrel 2. The plurality of cleaning rollers 24 are driven by a sliding mechanism. A disposable sterilizing cotton is detachably mounted on the plurality of cleaning rollers 24. The sterilizing effect on the needle receiving part of the patient can be achieved by the driving of the sliding mechanism. The compression barrel 2 drives the sliding mechanism to work by pressing downward; A first through hole 1302 is provided on the bottom wall of the fixed shell 13, and a fixed barrel 17 is connected and installed at the upper end of the first through hole 1302. The fixed barrel 17 is arranged between the two pressurizing components, and the fixed barrel 17 is connected and arranged with the compression barrel 2. Its function is to release the air pressure in the compression barrel 2 from the fixed barrel 17 through the reciprocating mechanism described later, so as to lift the compression barrel 2 and reduce the compression force. A sliding plate 18 is slidably mounted on the right side wall of the fixed barrel 17. The sliding plate 18 can slide back and forth under the drive of the reciprocating mechanism described later, and the air pressure in the compression barrel 2 is periodically released during the reciprocating sliding process. The sliding plate 18 is driven to slide by the reciprocating mechanism, and the sliding plate 18 drives the compression barrel 2 to lift up by reciprocating sliding; A driving mechanism is installed at the upper end of the mounting plate 1, and the driving mechanism is arranged on one side of the compression barrel 2, and the reciprocating mechanism is driven to work by the driving mechanism; Fixing buckles 1011 are respectively installed on the two side walls of the expansion shell 101 , and the same fastening belt is detachably installed in the two fixing buckles 1011 . The device can be fixed on the patient's limb by passing the fastening belt through the two fixing buckles 1011 .

[0021] The pressurizing assembly includes a flexible air bag 16, a ventilation hose 15, a ventilation fixing tube 21, and a rotating disk 22; The two sides of the bottom wall of the fixed shell 13 are connected and installed with ventilation fixed pipes 21 respectively; The fixed barrel 17 is disposed between the two ventilation fixed pipes 21; The two ventilation fixing pipes 21 are both connected to the compression barrel 2; The upper ends of the two connecting pipes 2 are rotatably mounted with rotating disks 22, and the lower ends of the two rotating disks 22 are fixedly mounted with first semicircular disks 2201 through first connecting members. The two first connecting members are both arranged inside the two ventilation fixed pipes 21. The two ventilation fixing tubes 21 are respectively installed with second semi-circular disks 2101, and the two first semi-circular disks 2201 are respectively slidably arranged on the upper ends of the two second semi-circular disks 2101. An anti-leakage rubber ring is installed between the first semi-circular disk 2201 and the second semi-circular disk 2101 to prevent the pressurized air from flowing out. The upper ends of the two rotating disks 22 are respectively connected to the first end of the ventilation hose 15 installed; The second ends of the two ventilation hoses 15 are respectively installed with flexible air bags 16. The user reciprocally presses the two flexible air bags 16 to send the air pressure through the ventilation hoses 15 into the two ventilation fixed tubes 21. The gas enters the compression barrel 2 through the two ventilation fixed tubes 21. Since the fixed shell 13 is fixed, the air pressure will begin to squeeze the compression barrel 2 downward after entering the compression barrel 2, causing the compression barrel 2 to begin to slide downward. The contact portion between the compression barrel 2 and the fixed shell 13 is installed with an anti-leakage rubber ring to prevent the air pressure from flowing out. This is the prior art and will not be described in detail. When the compression barrel 2 slides downward After a certain distance, a certain compressive force is exerted. At this time, a sealing area is formed between the two first semi-disks 2201 and the second semi-disks 2101 in the two ventilation fixing tubes 21 by rotating the two rotating disks 22. At this time, stopping pressing the two flexible airbags 16 can achieve fixing the pressure of the compression barrel 2. It should be noted that when the second semi-disk 2101 and the first semi-disk 2201 overlap, it can ensure that the ventilation fixing tube 21 is blocked, and when the second semi-disk 2101 and the first semi-disk 2201 are staggered, the ventilation fixing tube 21 can be circulated again.

[0022] The sliding mechanism comprises a first connecting frame 29, a first connecting rod 3, a sliding rod 4, a third connecting shaft 401, a sliding rail 202, a fixing rod 5, a mounting rod 23, a first rectangular sliding block 25, a first return spring 26, and a wheel axle 27; First connecting frames 29 are fixedly mounted on the outer sides of the second ends of the two connecting rods 14; The first ends of the first connecting rods 3 are rotatably mounted in the two first connecting frames 29 respectively; The lower ends of the front and rear side walls of the compression barrel 2 are respectively installed with slide rails 202, and the two slide rails 202 are respectively installed with slide rods 4 slidingly passing through them; The first ends of the third connecting shafts 401 are fixedly mounted on the inner walls of the first ends of the two sliding rods 4, and the second ends of the two first connecting rods 3 are rotatably sleeved on the outer sides of the second ends of the two third connecting shafts 401; The lower parts of the second ends of the two slide bars 4 are fixedly mounted with fixed bars 5 through second connecting members, and gaps are left between the two slide bars 4 and the two fixed bars 5; The bottom walls of the two slide rails 202 can be detachably slidably disposed in the two gaps; The inner walls of the two fixing rods 5 are both mounted with mounting rods 23; The inner walls of the two mounting rods 23 are provided with a plurality of evenly distributed first rectangular sliding grooves 2301; A first rectangular slide block 25 is slidably installed in each of the first rectangular slide grooves 2301, and the first rectangular slide blocks 25 are fixedly connected to the bottom wall of the first rectangular slide groove 2301 that cooperates with the first return spring 25; A plurality of first rectangular sliding blocks 25 located on two opposite sides are fixedly connected by a wheel axle 27; A plurality of cleaning rollers 24 are rotatably sleeved on the outer sides of a plurality of wheel shafts 27; A plurality of cleaning rollers 24 can be detachably rolled on the lower end of the pressure barrel 2. The pressure barrel 2 will gradually lift up and reduce the pressure force under the drive of the reciprocating mechanism described later. When the pressure barrel 2 is on the stage, it will drive the sliding rods 4 on both sides to start lifting up. When the two sliding rods 4 are lifted up, they will also drive the third connecting shafts 401 on both sides to lift up. Since the fixed shell 13 and the mounting plate 1 are both fixed, the two connecting rods 14 fixedly mounted on the fixed shell 13 and the mounting plate 1 are also fixed. At this time, when the two third connecting shafts 401 are lifted up, they will gradually approach the mounting plate 1, which will cause the first connecting rods 3 on both sides to start rotating upward. Figure 1When the first connecting rods 3 on both sides rotate upward, they will pull the two sliding rods 4 to slide to the left through the two third connecting shafts 401 respectively. When the two sliding rods 4 slide to the left, they will drive the two fixed rods 5 to slide to the left respectively. The mounting rods 23 fixedly mounted on the inner walls of the two fixed rods 5 also start to slide to the left at this time. The cleaning rollers 24 located between the two mounting rods 23 also start to slide to the left at this time. When the cleaning rollers 24 contact the lower bottom wall of the compression barrel 2, the first return springs 26 start to compress, so that the cleaning rollers 24 can slide between the compression barrel 2 and the patient's needle receiving site to play a disinfecting role.

[0023] The reciprocating mechanism comprises a second connecting frame 1801, a second connecting rod 19, a third connecting frame 20, a second rectangular sliding block 1803, a rectangular block 28, a rack plate 12, a spur gear 11, and a second return spring 6; Rectangular blocks 28 are fixedly mounted on both ends of the right wall of the fixed barrel 17; Rectangular through slots 2801 are respectively provided in the two rectangular blocks 28; The second rectangular sliding blocks 1803 are slidably installed in the two rectangular through grooves 2801 respectively, and the sliding plate 18 is fixedly arranged between the two second rectangular sliding blocks 1803; The sliding plate 18 is provided with a first rectangular through hole 1802 , and the right side wall of the fixed barrel 17 is provided with a second rectangular through hole 1701 , and the second rectangular through hole 1701 is provided between the two rectangular blocks 28 ; The first rectangular through hole 1802 and the second rectangular through hole 1701 are in detachable contact with each other; A second connecting frame 1801 is installed below the first rectangular through hole 1802, and the second connecting frame 1801 is fixed on the right side wall of the sliding plate 18; The first end of the second connecting rod 19 is rotatably mounted in the second connecting frame 1801; A second rectangular slide groove 102 is provided at the upper end of the mounting plate 1, and a horizontal plate of a T-shaped slider is slidably installed in the second rectangular slide groove 102; A third connecting frame 20 is installed on the upper end of the vertical plate of the T-shaped slider; The second end of the second connecting rod 19 is rotatably disposed in the third connecting frame 20; A rack plate 12 is fixedly mounted on one side of the third connecting frame 20; A spur gear 11 is meshed and mounted on one side of the rack plate 12, and the spur gear 11 is rotatably mounted on the upper end of the mounting plate 1 via a rotating shaft; The spur gear 11 is driven by the driving mechanism to reciprocate; Stoppers 201 are respectively installed at the upper ends of the front and rear side walls of the compression barrel 2, and both stoppers 201 are movably arranged above the mounting plate 1; The lower ends of the two stoppers 201 are fixedly connected to the upper end of the mounting plate 1 through the second return spring 1803 respectively. The spur gear 11 starts to reciprocate under the drive of the driving mechanism, and drives the rack plate 12 meshing therewith to start reciprocating sliding during the reciprocating rotation. The third connecting frame 20 fixedly mounted on the rack plate 12 also starts to reciprocate along with the rack plate 12. The third connecting frame 20 is fixedly connected to the vertical plate of the T-shaped slider, and the sliding trajectory of the T-shaped slider is limited by the second rectangular slide groove 102, so the sliding trajectory of the rack plate 12 is also determined. The third connecting frame 20 drives the second connecting rod 19 to start to deflect up and down during the reciprocating sliding process. Figure 5 In the process of up and down deflection, the second connecting rod 19 will drive the sliding plate 18 to start sliding up and down along the rear wall of the fixed barrel 17. The fixed barrel 17 limits the sliding track through the cooperation of the second rectangular slider 1803 and the rectangular slider 2801 on both sides. In the process of reciprocating sliding, the sliding plate 18 will form a periodic contact between the first rectangular through hole 1801 and the second rectangular through hole 1701. Whenever the two rectangular through holes contact each other, the air pressure inside the compression barrel 2 will be connected to the external air pressure. Whenever the compression barrel 2 is connected to the external air pressure When the environment is open, the second return spring 6 begins to reset and lifts the compression barrel 2 upward to reduce the pressure on the patient's needle-receiving part, until the two rectangular through holes slide to a completely staggered position, and the compression barrel 2 is isolated from the external air pressure again, and the second return spring 6 cannot be reset. At this time, the compression force of the compression barrel can be fixed at the reduced force. It should be noted that, except for the two rectangular through grooves, the sliding plate 18 and the fixed barrel 17 are all in closed contact, which is achieved by installing a leak-proof air ring to avoid air leakage. This is the prior art and will not be elaborated here.

[0024] The driving mechanism comprises a third connecting rod 10, a fourth connecting rod 9, a fifth connecting rod 8, a driving motor, and a third rectangular sliding block 30; The first end of the third connecting rod 10 is fixedly mounted at the center of the upper end of the spur gear 11; A third rectangular slide groove 1001 is provided in the third connecting rod 10, a third rectangular slider 30 is slidably installed in the third rectangular slide groove 1001, an adjusting mechanism for adjusting the amplitude of the reciprocating mechanism is installed on one side of the third rectangular slider 30, and the third rectangular slider 30 is driven to slide by the adjusting mechanism; A fourth connecting shaft is installed at the upper end of the third rectangular slider 30, and a first end of a fourth connecting rod 9 is rotatably mounted on the fourth connecting shaft; The lower part of the second end of the fourth connecting rod 9 is rotatably mounted with the first end of the fifth connecting rod 8 via the fifth connecting shaft; A driving motor 7 is mounted on the upper end of the mounting plate 1, and the driving motor 7 is arranged on one side of the spur gear 11; The second end of the fifth connecting rod 8 is fixedly sleeved on the output shaft of the driving motor 7. When the user starts the driving motor 7, the output end of the driving motor 7 drives the fifth connecting rod 8 coaxially fixed therewith to start rotating. During the rotation, the fifth connecting rod 8 drives the fourth connecting rod 9 hinged thereto to start reciprocating deflection. The fourth connecting rod 9 drives the third rectangular slider 30 rotatably mounted therewith to start reciprocating movement through the reciprocating deflection. The movement trajectory of the third rectangular slider 30 is limited by the third rectangular slide groove 1001. Therefore, the third rectangular slider 30 transmits the driving force of its own reciprocating movement to the third connecting rod 30 through the third rectangular through groove 1001, so that the third connecting rod 30 can reciprocate. During the reciprocating deflection, the third connecting rod 30 drives the spur gear 11 coaxially mounted therewith with the rotation center, so that the spur gear 11 has the ability to reciprocate.

[0025] The adjustment mechanism includes an adjustment screw 31 and a knob 3101; The third rectangular sliding block 30 is internally threaded with an adjusting screw 31, and the first end of the adjusting screw 30 is rotatably mounted on the first side wall of the third rectangular sliding groove 1001; The second end of the adjusting screw 30 rotates to pass through the second side wall of the third rectangular through slot 1001 and is fixedly installed with a knob 3101. The user can rotate the knob 3101 to make the third rectangular slider 30 slide and limit in the third rectangular slot 1001. The third rectangular slider 30 can change the deflection angle of the fourth connecting rod 9 by sliding. After the deflection angle of the fourth connecting rod 9 changes, it can be turned over to change the deflection angle of the third connecting rod 10 through the third rectangular slider 30. The third connecting rod 10 adjusts the reciprocating rotation amplitude of the spur gear 11 by changing the angle. The reciprocating rotation amplitude of the spur gear 11 indirectly changes the reciprocating sliding process of the rack plate 12 so that the sliding plate 18 can slide in different processes. The sliding plate 18 is adjusted by different The same process sliding indirectly changes the frequency of mutual contact between the first rectangular through hole 1802 and the first rectangular through hole 1701. When the frequency of contact between the two rectangular through holes is faster, the air pressure inside the compression barrel 2 is released faster. When the frequency of contact between the two rectangular through holes is slower, the air pressure inside the compression barrel 2 is released slower. It should be noted that when the frequency of contact between the two rectangular through holes is faster, although the number of contacts between the two rectangular through holes is accelerated, the contact time each time will also be shortened accordingly. When the frequency of contact between the two rectangular through holes is slower, although the number of contacts between the two rectangular through holes is reduced, the contact time each time will also be lengthened accordingly. Therefore, it is necessary to adjust the speed of the drive motor 7 so that the sliding plate 18 can only control the leakage time through the amplitude.

[0026] A disposable flexible pad is detachably mounted at the lower end of the compression barrel 2, and its function is to protect the patient's limbs from forming a rigid contact with the compression barrel 2. A circular groove 203 for removing the needle is provided at the lower end of the disposable flexible pad, and its function is to facilitate needle removal and prevent the bottom of the compression barrel 2 from directly contacting the needle body.

[0027] Implementation method of the present invention: The fastening belt of the device is passed through the two fixing buckles 1011 and wrapped around the outside of the patient's limb to be needled, and the two rotating disks 22 are rotated to lift the compression barrel 2 to the highest position, and the circular groove 203 at the lower end of the disposable flexible pad is aligned with the needle body on the patient's limb to start reciprocatingly pressing the two flexible airbags 16; The doctor presses the flexible airbag 16 back and forth to gradually press the compression barrel 2 downward. When the side wall of the circular groove 203 contacts the needle body, the doctor quickly pulls out the needle body and quickly presses the flexible airbags 16 on both sides, so that the compression barrel 2 is quickly pressed downward to stop the bleeding of the patient and achieve preliminary hemostasis. The doctor needs to determine the pressing force to be used according to the bleeding condition of the patient. By pressing the flexible airbag 16, the effect of supplementing air pressure and increasing the pressing force can be achieved. When the compression barrel 2 compresses the bleeding part of the patient with a certain force, the two rotating disks 22 are rotated in the opposite direction to form a seal between the two first semi-circular disks 2201 and the two second semi-circular disks 2101. The speed of the driving motor 7 is adjusted and the driving motor is started. At this time, the sliding plate 18 starts to slide on the rear side wall of the fixed barrel at a periodic frequency. When the sliding plate 18 slides back and forth, the first rectangular through hole 1701 and the second rectangular through hole 1802 will contact each other at a certain frequency. Whenever the two rectangular through holes contact each other, the pressure in the compression barrel 2 will be released, resulting in the phenomenon that the compression barrel 2 is lifted up. The compression barrel 2 achieves a slow reduction of the pressure on the bleeding site by slowly lifting up. After a period of time, the compression barrel 2 is slowly lifted to the highest position. During the lifting process of the compression barrel 2, several cleaning rollers 24 located at the lower end thereof also begin to move toward the lower end of the compression barrel 2, and finally move to between the compression barrel 2 and the patient's bleeding limb, playing the role of wiping blood and disinfecting.

[0028] Doctors can also adjust the pressure relief frequency through the regulating mechanism according to the patient's bleeding situation, so as to meet the hemostasis needs of patients in different situations.

[0029] The compression barrel of the present invention can effectively compress the puncture site of the patient with the cooperation of the pressure component, and the pressing force can be adjusted by the pressure component. The reciprocating mechanism of the present invention can effectively and periodically gradually reduce the pressing force of the pressure component on the puncture site, thereby avoiding frequent human intervention. The sliding mechanism of the present invention can drive the cleaning roller to disinfect the patient's puncture site when the pressure component stops pressing the patient's puncture site.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
