Description

Technical Field

[0001] The present invention relates to the technical field of compression hemostasis, and more specifically, it relates to a hemostatic compression device for interventional therapy. Background Art

[0002] Currently, there are mainly three types of methods widely used in clinical practice at home and abroad for hemostasis at the puncture site after transarterial interventional therapy: manual compression, vascular compression hemostat, and vascular closure device. Manual compression hemostasis is the most traditional and currently the most commonly used arterial hemostasis method. Its advantages lie in being economical and relatively reliable, and it can be used to remedy the failure of the hemostasis method. However, it requires an experienced physician to compress for 15 minutes or even longer, which exacerbates the pain of the patient.

[0003] Vascular closure devices can be roughly divided into puncture tract embolization types, vascular suture types, and puncture tract temporary occlusion types, etc. Vascular closure devices have great superiority in many aspects, such as exact hemostasis and being applicable to the closure of larger puncture sites such as abdominal aortic aneurysms. The arterial compression hemostat is a hemostatic device applied after vascular interventional surgery, mainly used for arterial compression. It mainly applies mechanical compression force to compress the arterial puncture site from outside the body to promote the hemostasis and healing of the puncture opening. In cases such as patient obesity, too high or too low puncture site, and poor patient cooperation, it will cause difficulties in compression, local hematoma, pseudoaneurysm, arteriovenous fistula, and lower extremity venous thrombosis, etc., and in severe cases, it can endanger life.

[0004] To meet the clinical demand for continuous, stable, and controllable compression, the compression hemostat came into being. Its design focuses on providing reliable pressure. This device is usually designed to be firmly worn on adjacent body surface positions such as the wrist or thigh that are easy to fix. By turning a specific control knob, it can drive the internal mechanism to convert into a stable and vertical downward pressure of the wireless ultrasonic probe towards the wound. However, since the compressor physically covers the puncture site and blocks the view, the operator cannot confirm whether the blood vessel is accurately covered, resulting in the deviation of the hematoma compression point. Therefore, the present invention provides a hemostatic compression device for interventional therapy. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the weak vibration generated under the action of the pulsating pressure of blood flow in the blood vessel is amplified by the pressing assembly. When a pressure wave generated by the pulsation of the blood vessel acts on the piezoelectric sheet, the piezoelectric sheet generates a weak mechanical vibration, and then it is conducted through the waveguide. The conducted energy drives the air in the resonant cavity, thereby causing the film to vibrate. At this time, the highly reflective particles on the film vibrate accordingly. Thus, under ambient light, the high-frequency flicker or blurred vibration image on the surface of the film can be directly observed by the naked eye, similar to the "water surface reflection" effect.

[0018] 2. In the present invention, a wireless ultrasonic probe is installed at the bottom end of the pressing tube. While pressing to stop bleeding, it can display the arterial state in real time and intuitively, without relying on an external ultrasonic instrument or wire harness, greatly improving the safety and controllability of the hemostasis process.

[0019] 3. In the present invention, the first motor drives the first gear to rotate. Since the first gear is meshed and connected to the inner side of the first toothed ring, the first toothed ring is driven to rotate synchronously. While the first toothed ring rotates, the positioning rod is driven to rotate. While the positioning rod moves, the limiting part is driven to move synchronously, thus driving the catheter to deviate within a small range, which is convenient for medical staff to observe the weak pulsation of blood vessels.

[0020] 4. In the present invention, the device can be divided into the compression of the femoral artery and the radial artery. When in use, the first strap and the second strap are sequentially installed on the first ear part and the second ear part through the magic tape as needed, so as to adapt to different artery compressions.

Detailed implementation manners

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0036] Embodiment 1 further describes an anti - bleeding compression device for interventional therapy proposed by the present invention, including a cover pressing plate body 100. A circular convex part 101 protrudes upward at the middle position of the cover pressing plate body 100. A perforation 102 is formed inside the circular convex part 101. The upper end surface of the circular convex part 101 is rotatably connected to a telescopic rod 103 in a circumferential manner. One end of a plurality of telescopic rods 103 is rotatably connected to a fixed sleeve 104. A compression assembly 200 is arranged inside the fixed sleeve 104. As is known from Figures 1 to 4 it can be seen that the outer side of the fixed sleeve 104 is rotatably connected to the telescopic rod 103 in a circumferential manner, and the other end of the telescopic rod 103 is rotatably connected to the upper end surface of the circular convex part 101, and the position of the fixed sleeve 104 is limited by the telescopic rod 103;

[0037] In the prior art, since the compression assembly 200 physically covers the puncture point and completely blocks the view, the operator cannot confirm whether the blood vessel is accurately covered. In this device, by setting the compression assembly 200 and the adjustment assembly, the weak vibration generated by the ultrasonic wave under the action of the blood flow pulsation pressure in the blood vessel is utilized. In this way, it is amplified and converted into a visual signal by the compression assembly 200, so as to facilitate the medical staff to observe;

[0038] As is known from Figure 1 and Figure 11 it can be seen that this device can be divided into two situations. One - side ears 105 and two - side ears 106 are integrally formed on both sides of the cover pressing plate body 100. The two - side ears 106 are detachably arranged on the cover pressing plate body 100. The one - side ears 105 and the two - side ears 106 are respectively two groups. An opening one 105a and an opening two 106a are respectively arranged inside the one - side ears 105 and the two - side ears 106;

[0039] When performing cylindrical compression on fixed parts such as the radial artery, brachial artery, and popliteal artery, a strap one 107 that can be wound around the wrist is used. The position of the strap one 107 is locked through Velcro. The connection part of the strap one 107 is wound around the cover pressing plate body 100. When the strap 107 is wound around the patient's wrist, at this time, the cover pressing plate body 100 will be placed in the patient's puncture area. Then, the compression block in the compression assembly 200 presses on the puncture point, so as to realize the positioning and pressing of the puncture point, and the wireless ultrasonic probe 201c can be finely adjusted through the adjustment mechanism 300;

[0040] When performing femoral artery compression and replacing, a strap two 108 is arranged inside the adjacent opening one 105a and opening two 106a. The straps 108 are respectively connected to the adjacent one - side ears 105 and two - side ears 106 to form a ring. One group of straps 108 is fixed to the thigh of the compressed limb through Velcro, and the other group of straps 108 is fixed to the iliac spines on both sides of the waist;

[0041] The compression assembly 200 includes a compression member 201 disposed within the fixed sleeve 104. An auxiliary member 202 for amplifying vibration is disposed within the compression member 201. The compression member 201 and the auxiliary member 202 cooperate to monitor the patient. It further includes an adjustment mechanism 300 disposed within the compression member 201. The adjustment mechanism 300 includes an annular member 301 disposed outside the compression member 201. A displacement member 302 is disposed on the annular member 301. A fixing member 303 is disposed within the compression member 201. The displacement member 302 and the fixing member 303 cooperate to amplify the weak vibration generated under the action of the blood flow pulsation pressure within the blood vessel through the compression assembly 200, and the adjustment mechanism 300 enables the compression assembly 200 to be finely adjusted during actual use. Thus, under ambient light, the high-frequency flicker or blurred vibration image on the surface of the film 202d can be directly observed by the naked eye. When the blood vessel is unobstructed, obvious regular flickers can be seen. When the blood vessel is compressed, the flicker disappears or is extremely weak;

[0042] It further includes an auxiliary mechanism 400. The auxiliary mechanism 400 includes a rotating member 401 disposed outside the fixed sleeve 104. The rotating member 401 adjusts the state of the compression member 201. A support member 402 is further disposed at the bottom of the cover pressing plate body 100. A deflecting member 403 is disposed within the support member 402. It adjusts the position of the compression assembly 200 in the vertical direction through the rotating member 401, and at the same time finely adjusts the angle of the compression member 201 through the deflecting member 403. Thus, during use, the state of the compression assembly 200 can be adjusted.

[0043] Working principle: During use, through the first strap 107 that can be wound around the wrist, its Velcro locks the position of the strap 107. The first strap 107 is wound around the connection of the cover pressing plate body 100. When the first strap 107 is wound around the patient's wrist, at this time, the cover pressing plate body 100 will be placed in the puncture area of the patient. Then, the wireless ultrasonic probe within the compression assembly 200 presses on the puncture point, thereby realizing the positioning and pressing of the puncture point. The position of the compression assembly 200 in the vertical direction is adjusted through the rotating member 401, and the angle of the compression member 201 is finely adjusted through the deflecting member 403, so as to ensure the accuracy of the compression member 201 during positioning and pressing. And the weak vibration generated under the action of the blood flow pulsation pressure within the blood vessel is amplified through the compression assembly 200, and at the same time the adjustment mechanism 300 enables the compression assembly 200 to be finely adjusted during actual use. Thus, under ambient light, the high-frequency flicker or blurred vibration image on the surface of the film 202d can be directly observed by the naked eye. When the blood vessel is unobstructed, obvious regular flickers can be seen. When the blood vessel is compressed, the flicker disappears or is extremely weak.

[0044] Embodiment Two

[0045] On the basis of the first embodiment, the following technical features are added: The compression assembly 200 includes a compression member 201 disposed within the fixed sleeve 104. An auxiliary member 202 for amplifying vibration is disposed within the compression member 201. The compression member 201 and the auxiliary member 202 cooperate to monitor the patient. The compression member 201 includes a cavity 201a disposed within the fixed sleeve 104. A compression tube 201b is movably connected within the cavity 201a. The bottom end of the compression tube 201b is fixedly connected to a wireless ultrasonic probe 201c. An activity cavity 201d is formed within the compression tube 201b. A stepped portion 201e is formed within the activity cavity 201d. A compression port 201f is formed within the wireless ultrasonic probe 201c. The compression port 201f communicates with the activity cavity 201d;

[0046] It can be seen from Figures 3 to 8 that the compression tube 201b can move vertically within the fixed sleeve 104. The bottom end of the compression tube 201b is equipped with a wireless ultrasonic probe 201c. The wireless ultrasonic probe 201c is a wireless ultrasonic probe. While compressing and stopping bleeding, it can display the arterial state in real time and intuitively, without relying on an external ultrasonic instrument or wire harness, greatly improving the safety and controllability of the hemostasis process. Moreover, the structure of the compression tube 201b of this device is further defined. A cylindrical activity cavity 201d is formed within the compression tube 201b. A stepped portion 201e is formed within the activity cavity 201d. An adjustment mechanism 300 is provided within the stepped portion 201e. The position of the compression tube 201b can be offset through the adjustment mechanism 300;

[0047] It can be seen from Figures 6 to 11 that the wireless ultrasonic probe 201c transmits the image to the host computer. The host computer performs AI recognition on the image. If it recognizes that the artery is being compressed, a relatively large arterial pressure is applied for compression. If it recognizes that the vein is being compressed, a relatively small venous pressure is applied for compression. If it recognizes that the subcutaneous fat of the patient is relatively thick, a greater compression force is applied. Otherwise, the compression force is reduced. If it recognizes situations such as local hematoma, pseudoaneurysm, etc., an alarm is sent to notify the medical staff for timely adjustment and further treatment. Specific pressure values need to be obtained based on clinical data collection;

[0048] The auxiliary member 202 includes a piezoelectric sheet 202a disposed within the compression port 201f. The upper end surface of the piezoelectric sheet 202a is fixedly connected to a catheter 202b. The upper end surface of the catheter 202b is connected to a resonance block 202c. A thin film 202d is installed on the upper end surface of the resonance block 202c. The diameter of the resonance block 202c gradually increases from bottom to top. An observation window 202e is installed on the upper end surface of the fixed sleeve 104. The thin film 202d is disposed within the observation window 202e;

[0049] By placing a small piezoelectric sheet 202a at the central position of the compression port 201f, the piezoelectric sheet 202a can make a small range of offset within the compression port 201f. The piezoelectric sheet 202a is a piezoelectric ceramic sheet and only serves as a transducer without a circuit. The piezoelectric sheet 202a faces the blood vessel below the puncture point. The upper end face of the piezoelectric ceramic sheet is connected to a catheter 202b. The catheter 202b is a rigid metal or hard polymer hollow waveguide 202b, and the inside of the catheter 202b is air or a specific damping liquid. The waveguide 202b is strip-shaped and can optimize the acoustic wave conduction. The end of the catheter 202b is connected to a resonant block 202c. The resonant block 202c is a small transparent sealed cavity, and a layer of ultra-thin, highly elastic, transparent film 202d is covered on the top of the resonant block 202c. The film 202d is a polyester film 202d, and high-reflective particles are coated on the outside of the film 202d;

[0050] An observation window 202e is installed on the upper end face of its fixing sleeve 104. The film 202d and the resonant cavity are located below the transparent observation window 202e on the surface of the device. When the blood vessel pulsation generates a pressure wave acting on the piezoelectric sheet 202a, the piezoelectric sheet 202a generates a weak mechanical vibration, and then it is conducted through the waveguide 202b. The conducted energy drives the air in the resonant cavity, thereby causing the film 202d to vibrate. At this time, the high-reflective particles on the film 202d vibrate accordingly. Thus, under ambient light, the naked eye can directly observe the high-frequency flicker or blurred vibration image on the surface of the film 202d, similar to the "water surface reflection" effect. When the blood vessel is unobstructed, obvious regular flickers can be seen, and its regularity is synchronized with the pulse. When the blood vessel is compressed, the flicker disappears or is extremely weak;

[0051] Working principle: As can be seen from Embodiment 1, during use, the compression block in the compression assembly 200 applies pressure to the puncture point, thereby realizing the positioning and pressing of the puncture point. When the blood vessel pulsation generates a pressure wave acting on the piezoelectric sheet 202a, the piezoelectric sheet 202a generates a weak mechanical vibration, and then it is conducted through the waveguide 202b. The conducted energy drives the air in the resonant cavity, thereby causing the film 202d to vibrate. At this time, the high-reflective particles on the film 202d vibrate accordingly. Thus, under ambient light, the naked eye can directly observe the high-frequency flicker or blurred vibration image on the surface of the film 202d, similar to the "water surface reflection" effect. When the blood vessel is unobstructed, obvious regular flickers can be seen, and its regularity is synchronized with the pulse. When the blood vessel is compressed, the flicker disappears or is extremely weak. Thus, the staff can see the above situation through the observation window 202e, thereby amplifying the weak vibration generated under the action of the blood flow pulsation pressure in the blood vessel, which is convenient for medical staff to observe.

[0052] Embodiment Three

[0053] On the basis of the second embodiment, the following technical features are added: It further includes an adjusting mechanism 300 arranged in the pressing member 201. The adjusting mechanism 300 includes an annular member 301 arranged outside the pressing member 201. An offset member 302 is arranged on the annular member 301. A fixing member 303 is arranged in the pressing member 201. The offset member 302 and the fixing member 303 cooperate with each other. The annular member 301 includes a first gear ring 301a rotatably connected to the bottom end of the stepped portion 201e. A first gear 301b is meshed and connected to the inner side of the first gear ring 301a. A first motor 301c is detachably installed at the bottom end of the stepped portion 201e. The first gear 301b is fixedly connected to the rotor shaft end of the first motor 301c;

[0054] It can be seen from Figures 6 to 9 that through the adjusting mechanism 300, the pressing assembly 200 can be finely adjusted during actual use. A first motor 301c is detachably installed at the bottom end of the stepped portion 201e. The first motor 301c is a micro motor and is adjusted by an external controller. The bottom end of the stepped portion 201e is rotatably connected to the first gear ring 301a through a bearing. The first motor 301c drives the first gear 301b to rotate. Since the first gear 301b is meshed and connected to the inner side of the first gear ring 301a, the first gear ring 301a is driven to rotate synchronously;

[0055] The offset member 302 includes a fan-shaped hole 302a arranged in the stepped portion 201e. A positioning rod 302b is integrally formed on the upper end surface of the gear ring. A limiting portion 302c is fixedly connected to the upper end surface of the positioning rod 302b. The positioning rod 302b is slidably connected in the fan-shaped hole 302a. The fixing member 303 includes a fixing plate 303a fixedly connected to the outer wall of the conduit 202b. An inclined hole 303b is arranged on the upper end surface of the fixing plate 303a. The corresponding limiting portion 302c is slidably connected in the inclined hole 303b;

[0056] It can be seen from the figure that the fan-shaped hole 302a is arranged inside the stepped portion 201e. A cylindrical positioning rod 302b is fixedly connected to the upper end surface of the gear ring. The positioning rod 302b is slidably connected in the fan-shaped hole 302a. A limiting portion 302c is fixedly connected to the upper end surface of the positioning rod 302b. At the same time, a fixing plate 303a is fixedly connected to the side wall of the conduit 202b, and a long strip-shaped inclined hole 303b is arranged on the fixing plate 303a. The corresponding limiting portion 302c is slidably connected in the inclined hole 303b. In this way, when the first gear ring 301a rotates, the positioning rod 302b is driven to rotate. When the positioning rod 302b moves, the limiting portion 302c is driven to move synchronously. In this way, the conduit 202b is driven to offset within a small range;

[0057] Working principle: As can be seen from Embodiment 2, when the position of the piezoelectric sheet 202a needs to be finely adjusted, the external controller starts the first motor 301c, and the first motor 301c drives the first gear 301b to rotate. Since the first gear 301b is meshed and connected to the inner side of the first gear ring 301a, the first gear ring 301a is driven to rotate synchronously. While the first gear ring 301a rotates, the positioning rod 302b is driven to rotate. While the positioning rod 302b moves, the limiting part 302c is driven to move synchronously, so as to drive the catheter 202b to offset within a small range, facilitating medical staff to observe the weak pulsation of blood vessels.

[0058] Embodiment 4

[0059] On the basis of Embodiment 3, the following technical features are added: The rotating part 401 includes a second gear ring 401a rotatably connected to the outside of the fixed sleeve 104 through a bearing. Three groups of auxiliary ports 401b are annularly arranged inside the fixed sleeve 104. The inner wall of the second gear ring 401a is fixedly connected with connecting blocks 401c in a circumferential manner. A sleeve 401d is fixedly connected between multiple groups of connecting blocks 401c. A positioning block 401e is integrally formed on the inner wall of the sleeve 401d. An arc-shaped groove 401f is provided on the outer wall of the compression tube 201b. The positioning block 401e is slidably connected to the arc-shaped groove 401f correspondingly. An installation frame 401g is fixedly connected to the outside of the fixed sleeve 104. A worm 401h is rotatably connected inside the installation frame 401g. The worm 401h meshes with the second gear ring 401a.

[0060] As Figures 4 to 10 can be seen, three arc-shaped auxiliary ports 401b are provided on the outside of the fixed sleeve 104. At the same time, a second gear ring 401a is rotatably connected to the outside of the fixed sleeve 104, and an installation frame 401g is fixedly connected to the outside of the fixed sleeve 104. The position of the installation frame 401g does not conflict with that of the gear ring. Since the worm 401h meshes with the second gear ring 401a, medical staff only need to rotate the worm 401h to drive the second gear ring 401a to rotate. While the second gear ring 401a rotates, the fixed sleeve 104 inside the connecting block 401c is driven to rotate synchronously.

[0061] Since a positioning block 401e is integrally formed on the inner wall of the sleeve 401d and an arc-shaped groove 401f is provided on the outer wall of the compression tube 201b, the positioning block 401e is slidably connected to the arc-shaped groove 401f correspondingly, so that the compression tube 201b moves in the vertical direction, thus adjusting the position of the wireless ultrasonic probe 201c at the bottom of the compression tube 201b in the vertical direction.

[0062] The support member 402 includes a support rod 402a fixedly connected to the bottom end of the cover pressing plate body 100 in a circumferential manner. At the bottom ends of multiple groups of support rods 402a, an annular plate 402b is fixedly connected. Two sliding grooves 402c are provided inside the annular plate 402b. A slider 402d is slidably connected in the two side sliding grooves 402c. An auxiliary spring 402e is fixedly connected to the side wall of the slider 402d. The auxiliary spring 402e is a carbon spring with high strength and is convenient for daily use. The auxiliary spring 402e is fixedly connected to the inner wall of the sliding groove 402c. The deflecting member 403 includes a motor three 403a detachably installed on the side wall of the annular plate 402b. A rotating rod one 403b is fixedly connected to the end of the rotor shaft of the motor three 403a. One end of the rotating rod one 403b passing through the annular plate 402b is fixedly connected to a rotating plate one 403c. A rotating plate two 403d is rotatably connected to the position on the inner wall of the annular plate 402b corresponding to the rotating plate one 403c. A connecting rod one 403e is fixedly connected to the corresponding positions of the rotating plate one 403c and the rotating plate two 403d. An activity ball 403f is fixedly connected to the middle position of the two connecting rods one 403e. The conduit 202b is arranged inside the activity ball 403f. The two side sliders 402d are rotatably connected to two corresponding connecting rods two 403g. The two corresponding connecting rods two 403g are fixedly connected to the outer wall of the activity ball 403f;

[0063] It can be seen from Figures 2 to 5 that at the bottom end of the cover pressing plate body 100, an annular plate 402b is fixedly connected through the support rod 402a. Arc-shaped sliding grooves 402c are symmetrically arranged inside the annular plate 402b. A slider 402d is connected in the sliding groove 402c through the auxiliary spring 402e. The motor three 403a is detachably installed on the outer wall of the annular plate 402b. The motor three 403a is adjusted by an external controller. The rotating rod one 403b is driven to rotate by the motor three 403a. While the rotating rod one 403b rotates, the rotating plate one 403c is driven to rotate. Since the rotating plate one 403c and the rotating plate two 403d are inclined, due to the inclined setting, the activity ball 403f at the middle position of the connecting rod one 403e is driven to deflect;

[0064] Working principle: It can be seen from Embodiment 3 that when the angle of the wireless ultrasonic probe 201c needs to be finely adjusted, the external controller adjusts the motor three 403a. The rotating rod one 403b is driven to rotate by the motor three 403a. While the rotating rod one 403b rotates, the rotating plate one 403c is driven to rotate. Since the rotation points of the rotating plate one 403c and the rotating plate two 403d are different, and the rotating plate one 403c and the rotating plate two 403d are inclined, the activity ball 403f inside the connecting rod one 403e is driven to deflect, so as to adjust the pressing tube 201b inside the activity ball 403f, achieving the effect of adjusting the angle of the wireless ultrasonic probe 201c.

[0065] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
