Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an artery compression device. Background Technology

[0002] Arterial compression is a common technique used in emergency or medical settings. It involves applying external pressure to the artery to reduce or control bleeding. It is frequently used in trauma management, surgical procedures, and hemostasis after arterial puncture.

[0003] Chinese patent CN110786909B discloses a compression hemostasis device for the puncture site after femoral artery intervention, including a compression hemostasis component. A first fixing band group and two second fixing band groups are connected to the side of the compression hemostasis component. Each first fixing band group includes two first bands, one end of which is connected to the side of the compression hemostasis component, and the other ends of which are connected to each other and fixed to the patient's pelvis. Each second fixing band group includes two second bands, one end of which is connected to the side of the compression hemostasis component, and the other ends of which are connected to each other and fixed to the patient's groin and thigh. A sterile dressing area is provided on the inner side of the compression hemostasis component, including a pressure block and a dressing chamber. The pressure block is located inside the dressing chamber, and the dressing chamber contains a dressing. However, this device still has the following problems during use:

[0004] When in use, the pressure hemostatic device comes into direct contact with the patient's puncture site. If the patient has a large amount of bleeding, the hemostatic effect of the device may decrease and it may become more susceptible to bacterial contamination, thus affecting the quality of wound compression.

[0005] Based on this, the present invention designs an arterial compression device to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides an arterial compression device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An artery compression device includes a compression base plate, an adjustable compression mechanism, a multi-angle suspension positioning mechanism, and an adjustable fixing mechanism;

[0009] An adjustable compression mechanism for applying pressure to the femoral artery puncture site to stop bleeding is installed in the middle of the pressing base plate.

[0010] The adjustable compression mechanism includes a pressure adjustment component, a rolling material replacement component, and a blood pressure band; the pressure adjustment component is connected to the pressure base plate; the rolling material replacement component is connected to the pressure adjustment component.

[0011] The left and right ends of the blood pressure cuff are respectively installed on the left and right sides of the rolling feed changing assembly;

[0012] The pressing base plate and the pressing degree adjustment assembly are also equipped with a multi-angle suspension positioning mechanism for adjusting the rotation direction of the blood pressure cuff.

[0013] The left and right ends of the pressing base plate are also equipped with adjustable fixation mechanisms for fixing the pressing base plate to the patient.

[0014] Furthermore, the pressing degree adjustment assembly includes a mounting cylinder, a drive screw, a drive knob, and a T-shaped moving plate; the mounting cylinder is rotatably mounted in the middle of the pressing base plate; a moving groove is formed inside the mounting cylinder; the upper end of the drive screw is rotatably connected to the top of the moving groove.

[0015] The T-shaped moving plate is threadedly connected to the drive screw; the T-shaped moving plate is slidably connected to the moving groove.

[0016] The drive knob is mounted on the upper end of the mounting cylinder and is fixedly connected to the drive screw.

[0017] The T-shaped moving plate is connected to the rolling material changing assembly;

[0018] Furthermore, the rolling material changing assembly includes a mounting plate, a micro drive motor, and a take-up roller; mounting plates are fixedly installed on both the left and right sides of the T-shaped moving plate; the micro drive motor is fixedly installed at the rear end of the mounting plate; the take-up roller is rotatably installed at the front end of the mounting plate; the output end of the micro drive motor is fixedly connected to the take-up roller.

[0019] The right end of the blood pressure band is fixedly installed on the inner ring of the right take-up roller, and the blood pressure band is wound around the take-up roller. The left end of the blood pressure band is fixedly connected to the inner ring of the left take-up roller.

[0020] Furthermore, the multi-angle hovering positioning mechanism includes a fixing ring, a locking tapered rod, and a reset spring; a fixing ring is fixedly installed on the lower outer end of the mounting cylinder; and a clearance groove is also provided on the upper side of the pressing base plate.

[0021] The fixed ring has symmetrical movable grooves at both ends; the locking conical rod is slidably connected to the movable groove; one end of the reset spring is fixedly connected to the inner wall of the movable groove; the other end of the reset spring is fixedly connected to the locking conical rod; the inner wall of the clearance groove has multiple locking grooves that are inserted into the locking conical rod at equal intervals around the circumference.

[0022] Furthermore, the locking groove has an inclined surface that expands toward the center of the fixing ring on the side near the center of the fixing ring;

[0023] Furthermore, the adjustable fixing mechanism includes an elastic strap, Velcro, and a tilting plate; tilting plates are symmetrically fixedly installed on the left and right sides of the lower end of the pressing base plate; the left end of the elastic strap is fixedly installed on the left tilting plate; Velcro is also fixedly installed on the elastic strap.

[0024] Furthermore, a through groove is provided on the right-side inclined plate;

[0026] Compared with the prior art, the beneficial effects of this invention are as follows: After the femoral artery puncture interventional surgery is completed, the medical staff will wrap the adjustable fixation mechanism around the patient's leg to fix the pressure plate to the patient's leg; since the femoral artery puncture wound usually has an irregular outline, the medical staff can control the rotation of the pressure adjustment component through the multi-angle suspension positioning mechanism, thereby adjusting the angle of the blood pressure band so that the blood pressure band is aligned with the puncture wound;

[0027] Then, by adjusting the pressure, the rolling material changing component is controlled to move toward the puncture wound until the tourniquet is pressed against the wound, thereby achieving hemostasis by compressing the patient's femoral artery.

[0028] If the patient is bleeding heavily, medical staff can also control the movement of the blood pressure cuff by using the rolling material changing component to prevent the blood pressure cuff from being in contact with the patient's wound for a long time, which would affect the blood absorption capacity and also prevent the growth of bacteria that would affect wound healing.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0040] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 An artery compression device includes a compression base plate 1, an adjustable compression mechanism 2, a multi-angle suspension positioning mechanism 3, and an adjustable fixing mechanism 4.

[0041] An adjustable compression mechanism 2 for applying pressure to the femoral artery puncture site to stop bleeding is installed in the middle of the pressing base plate 1;

[0042] The adjustable compression mechanism 2 includes a pressure adjustment component, a rolling material replacement component, and a blood pressure band 29; the pressure adjustment component is connected to the pressure base plate 1; the rolling material replacement component is connected to the pressure adjustment component.

[0043] The left and right ends of the blood pressure cuff 29 are respectively installed on the left and right sides of the rolling material changing assembly;

[0044] The pressing base plate 1 and the pressing degree adjustment assembly are also equipped with a multi-angle suspension positioning mechanism 3 for adjusting the rotation direction of the blood pressure band 29;

[0045] The left and right ends of the pressing base plate 1 are also equipped with adjustable fixing mechanisms 4 for fixing the pressing base plate 1 to the patient.

[0046] In this invention, after the femoral artery puncture interventional surgery is completed, the medical staff will wrap the adjustable fixation mechanism 4 around the patient's leg to fix the pressing base plate 1 to the patient's leg. Since the femoral artery puncture wound usually has an irregular outline, the medical staff can control the rotation of the pressing degree adjustment component through the multi-angle suspension positioning mechanism 3, thereby adjusting the angle of the blood pressure band 29 so that the blood pressure band 29 is aligned with the puncture wound.

[0047] Then, by adjusting the pressure, the rolling material changing component is controlled to move toward the puncture wound until the blood pressure band 29 is pressed against the wound to achieve hemostasis by compressing the patient's femoral artery.

[0048] If the patient has a large amount of bleeding, medical staff can also control the movement of the blood pressure cuff 29 by using the rolling material changing component to avoid the blood pressure cuff 29 being in contact with the patient's wound for a long time, which would affect the blood absorption capacity and also prevent the growth of bacteria that would affect wound healing.

[0049] Example 2: In some embodiments, such as Figures 1-6 As shown, in a preferred embodiment of the present invention, the pressing degree adjustment assembly includes a mounting cylinder 21, a drive screw 23, a drive knob 24, and a T-shaped moving plate 25; the mounting cylinder 21 is rotatably mounted in the middle of the pressing base plate 1; a moving groove 22 is provided inside the mounting cylinder 21; the upper end of the drive screw 23 is rotatably connected to the top end of the moving groove 22.

[0050] The T-shaped movable plate 25 is threadedly connected to the drive screw 23; the T-shaped movable plate 25 is also slidably connected to the movable groove 22.

[0051] The drive knob 24 is rotated and mounted on the upper end of the mounting cylinder 21 and is fixedly connected to the drive screw 23;

[0052] The T-shaped moving plate 25 is connected to the rolling material changing assembly;

[0053] The rolling material changing assembly includes a mounting plate 26, a micro drive motor 27, and a take-up roller 28; the mounting plate 26 is fixedly installed on both the left and right sides of the T-shaped moving plate 25; the micro drive motor 27 is fixedly installed at the rear end of the mounting plate 26; the take-up roller 28 is rotatably installed at the front end of the mounting plate 26; the output end of the micro drive motor 27 is fixedly connected to the take-up roller 28.

[0054] The right end of the blood pressure band 29 is fixedly installed on the inner ring of the right take-up roller 28, and the blood pressure band 29 is wound around the take-up roller 28. The left end of the blood pressure band 29 is fixedly connected to the inner ring of the left take-up roller 28.

[0055] The multi-angle hovering positioning mechanism 3 includes a fixing ring 31, a locking tapered rod 33, and a reset spring 35; the fixing ring 31 is fixedly installed on the lower side of the outer end of the mounting cylinder 21; a clearance groove 11 is also provided on the upper side of the pressing base plate 1;

[0056] The fixed ring 31 has symmetrical movable grooves 32 at its left and right ends; the locking conical rod 33 is slidably connected to the movable groove 32; one end of the reset spring 35 is fixedly connected to the inner wall of the movable groove 32; the other end of the reset spring 35 is fixedly connected to the locking conical rod 33; the inner wall of the clearance groove 11 has multiple locking grooves 34 that are inserted into the locking conical rod 33 at equal intervals around the circumference.

[0057] The locking groove 34 has an inclined surface that expands toward the center of the fixing ring 31 on the side near the center of the fixing ring 31;

[0058] In this invention, after medical personnel initially fix the device to the patient's leg using the adjustable fixation mechanism 4, they first twist the fixing ring 31 according to the location of the puncture wound, causing the mounting cylinder 21 to rotate. During the rotation, the inclined surface on the locking groove 34 controls the locking cone rod 33 to move along the movable groove 32 toward the center of the fixing ring 31. During the movement, the reset spring 35 is continuously compressed. Whenever the fixing ring 31 rotates a certain angle, the reset spring 35 will return to its original position, causing the locking cone rod 33 to reset, so that the locking cone rod 33 is reinserted into the locking groove 34 to fix the mounting cylinder 21. This continues until the blood pressure band 29 is aligned with the contour of the patient's wound.

[0059] Then, turn the drive knob 24 to rotate the drive screw 23, causing the T-shaped moving plate 25 to move downwards along the moving groove 22 toward the patient's wound until the blood pressure band 29 is pressed against the patient's wound, thereby achieving compression hemostasis of the patient's femoral artery.

[0060] If the patient has a large amount of bleeding, turn the drive knob 24 to make the T-shaped moving plate 25 move the blood pressure band 29 upward by one end, so that the blood pressure band 29 is separated from the patient's skin.

[0061] Then, the micro drive motors 27 on both sides are started simultaneously. At this time, the micro drive motor 27 on the right side controls the right take-up roller 28 to unwind the right side of the blood pressure band 29, and the micro drive motor 27 on the left side controls the left take-up roller 28 to take up the left side of the blood pressure band 29. This causes the part of the blood pressure band 29 that has been in contact with the patient's wound for a period of time to rotate and be wound onto the left take-up roller 28, while the unused part on the right side of the blood pressure band 29 will move to the bottom of the T-shaped moving plate 25 to continue the compression operation.

[0062] Example 3: In some embodiments, such as Figure 1As shown, in a preferred embodiment of the present invention, the adjustable fixing mechanism 4 includes an elastic strap 41, a Velcro 42, and an inclined plate 43; the inclined plates 43 are symmetrically fixedly installed on the left and right sides of the lower end of the pressing base plate 1; a through groove is provided on the right inclined plate 43; the left end of the elastic strap 41 is fixedly installed on the left inclined plate 43; the Velcro 42 is also fixedly installed on the elastic strap 41; and the right Velcro 42 is a hook surface; the left Velcro 42 is a rough surface.

[0063] In this invention, medical staff pull the left side of the elastic band 41 around the lower side of the patient's leg and bring out the right end of the elastic band 41 through the slot opened on the right inclined plate 43. Then, the right side of the elastic band 41 is glued and fixed to the left side of the elastic band 41 by Velcro 42, thereby fixing the device to the leg.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
