Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and more specifically, to a restraining hemostasis device for cardiac intervention. Background Art

[0002] Cardiac interventional surgery is a new technology for diagnosing and treating cardiovascular diseases. It is a method of puncturing surface blood vessels, inserting a cardiac catheter under continuous digital subtraction angiography, and using specific cardiac catheter operation techniques to diagnose and treat heart disease. It is a relatively advanced method for diagnosing and treating heart disease, and it is progressing very rapidly. It is between internal medicine treatment and surgical treatment, and is an invasive diagnosis and treatment method. It includes coronary angiography, PTCA+stent, mitral valve balloon angioplasty, radiofrequency ablation, pacemaker implantation, interventional treatment of congenital heart disease, and intracoronary thrombolysis. When the interventional surgery is completed, pressure hemostasis is usually used to stop bleeding at the punctured blood vessels on the surface of the body.

[0003] The current compression hemostasis method mainly performs artificial compression on the puncture point on the surface of the skin and some surrounding areas. However, in actual puncture operations, the needle is not inserted perpendicularly to the skin. Usually, the angle between the needle and the skin is very small, or even basically parallel to the skin. This causes the needle holes on the blood vessels and the skin and muscle tissue to be not on a vertical line. The damaged area caused by the puncture of the needle tip appears as a strip-like trajectory. At this time, only pressing the puncture point on the surface of the skin and its local area cannot control the bleeding at the needle hole position of the blood vessel, and may even cause large bruising and swelling at the puncture site. Therefore, the current compression hemostasis method still has great safety risks. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a restraining hemostasis device for cardiac intervention. By providing an arc-shaped pressure plate, a deformation groove and a positioning seat, the arc-shaped pressure plate can be used to press on the patient's puncture site in a gradually fitting and covering manner during the hemostasis process. The compression trajectory and direction are relatively distributed with the direction of the puncture trajectory, and then the puncture site is gradually pressurized from the inside to the outside, fully compressing the bleeding point from the internal bleeding point to the bleeding point on the surface of the skin. The restraining hemostasis method from the deep texture of the puncture site to the surface of the skin can effectively avoid adverse conditions such as congestion and swelling during the pressing process, and further improve its restraining hemostasis effect after cardiac intervention surgery, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a restraining hemostasis device for cardiac intervention, comprising a restraining belt, a belt buckle is fixedly installed on one side of the restraining belt, a connecting seat is arranged at the bottom end of the restraining belt, two arc-shaped pressure plates are symmetrically arranged on the left and right sides of the bottom end of the belt buckle, the two arc-shaped pressure plates together form an oval structure, the inner wall surfaces of the two arc-shaped pressure plates are equidistantly provided with a plurality of deformation notches from top to bottom, a positioning seat is commonly installed at the ends of the two arc-shaped pressure plates, and the two arc-shaped pressure plates are separated on the left and right sides of the surface of the positioning seat, a pair of arc-shaped grooves are symmetrically opened inside the positioning seat, a pair of limiting blocks are symmetrically fixed inside the positioning seat and on one side of the arc-shaped groove, and a semicircular pressure block is fixedly installed at the bottom end of the belt buckle;

[0006] The deformation notch includes an arc groove and a notch, and the opening degree from the arc groove to one side of the notch gradually increases and reaches a maximum value at the outer edge of the notch. The deformation notch and the overall arc track of the arc pressure plate are maintained in an inclined distribution, and the overall angle of the deformation notch always points to the oblique lower side of the arc pressure plate. The volumes of the three deformation notches located in the middle section of the arc pressure plate increase from bottom to top in sequence, and the inclination angles between the three deformation notches and the arc pressure plate gradually decrease from bottom to top;

[0007] The overall cross-section of the positioning seat is semicircular, with an arc-shaped top and a flat bottom. The overall trajectory of the arc groove is arc-shaped, and is closed in a semicircular form at the top of the arc, forming an involute-shaped gap between the bottom and the positioning seat and the limiting block. Both sides of the limiting block are arc-shaped trajectories, and the inner and outer arc-shaped trajectories of the limiting block are relatively distributed. The convex part of the inner arc-shaped trajectory of the limiting block and the concave part of one side of the inner wall of the arc groove are kept in opposite distribution.

[0008] The bottom end surface of the limiting block and the bottom end surface of the positioning seat are maintained in the same horizontal plane.

[0009] In a preferred embodiment, the deformation notches are in the shape of wedge-shaped notches as a whole, and the inclination angles of the plurality of deformation notches change synchronously with the trajectory of the arc-shaped pressure plate.

[0010] In a preferred embodiment, the overall side surface of the arc-shaped pressing plate is a sheet-like structure, and the entire arc-shaped pressing plate is made of a highly elastic material.

[0011] In a preferred embodiment, Velcro is attached to the inner and outer sides of both sides of the restraint belt.

[0012] In a preferred embodiment, the semicircular pressing block is in an arc shape as a whole, and the arc vertex of the semicircular pressing block and the vertex of the positioning seat are symmetrical to each other and are located on the same horizontal line.

[0013] In a preferred embodiment, the two side tracks of the limiting block together form a water drop-shaped structure, and the two side tracks of the limiting block are connected at the ends and maintain a seamless connection.

[0014] Technical effects and advantages of the present invention:

[0015] The present invention provides an arc-shaped pressure plate, a deformation notch and a positioning seat. During the hemostasis process, the arc-shaped pressure plate can be gradually pressed down under the winding and tightening operation of the restraint belt, and expand outward from the middle thereof, so as to ensure that the whole gradually deforms into a C-shape. At the same time, during the deformation process, a plurality of deformation notches provided on the arc-shaped pressure plate will shrink along the deformation trajectory of the arc-shaped pressure plate, so as to adapt to the deformation state of the arc-shaped pressure plate and provide directionality for its deformation process. In addition, during the deformation process, the arc-shaped pressure plate is pressed onto the puncture site of the patient in a manner of gradually fitting and covering. The compression trajectory and direction are relatively distributed with the direction of the puncture trajectory, so as to gradually apply pressure to the puncture site from the inside to the outside, fully compressing the bleeding points from the internal bleeding points to the bleeding points on the surface of the skin. The restrained hemostasis method in the direction from the deep texture of the puncture site to the surface of the skin can effectively avoid adverse conditions such as congestion and swelling during the pressing process, and further improve its restrained hemostasis effect and safety after cardiac intervention surgery.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] As attached Figure 1 To Attachment Fig.10 A restraining hemostasis device for cardiac intervention is shown, comprising a restraining belt 1, a belt buckle 2 is fixedly installed on one side of the restraining belt 1, a connecting seat 3 is arranged at the bottom end of the restraining belt 1, two arc-shaped pressing plates 4 are symmetrically arranged on the left and right sides of the bottom end of the belt buckle 2, and the two arc-shaped pressing plates 4 together form an oval structure, and the inner wall surfaces of the two arc-shaped pressing plates 4 are equidistantly provided with a plurality of deformation notches 5 from top to bottom, and a positioning seat 6 is installed at the ends of the two arc-shaped pressing plates 4, and the two arc-shaped pressing plates 4 are separated on the left and right sides of the surface of the positioning seat 6, and a pair of arc-shaped grooves 7 are symmetrically opened inside the positioning seat 6, and the interior of the positioning seat 6 and located on one side of the arc-shaped groove 7 are A pair of limiting blocks 8 are fixed symmetrically, and a semicircular pressure block 9 is fixedly installed on the bottom end of the strap buckle 2. The above arrangement can ensure that during the deformation of the arc-shaped pressure plate 4, the arc-shaped pressure plate 4 on one side can restrain hemostasis, while the arc-shaped pressure plate on the other side can further restrain the distal end of the blood vessel from the distal end while ensuring balance, thereby achieving the purpose of auxiliary hemostasis, and in the deformation process, a number of deformation notches 5 provided on the arc-shaped pressure plate 4 will shrink along the deformation trajectory of the arc-shaped pressure plate 4, thereby adapting to the deformation trend of the arc-shaped pressure plate 4, ensuring that the arc-shaped pressure plate 4 is compressed and deformed in a predetermined folding shape, providing directionality for its deformation process, and further improving the coordination and linkage accuracy between its structures.

[0029] The deformation notch 5 includes an arc groove 51 and a notch 52. The opening degree from the arc groove 51 to one side of the notch 52 gradually increases, and reaches a maximum value at the outer edge of the notch 52. The deformation notch 5 and the overall arc trajectory of the arc pressure plate 4 are maintained in an inclined distribution, and the overall angle of the deformation notch 5 always points to the oblique lower side of the arc pressure plate 4. The volumes of the three deformation notches 5 located in the middle section of the arc pressure plate 4 increase from bottom to top in sequence, and the three deformation notches 5 and the arc pressure plate 4 are connected. The inclination angle between them gradually decreases from bottom to top; through the above-mentioned arrangement, by utilizing the different volumes and angles of the three deformation notches 5 in the middle section of the arc-shaped pressure plate 4, it can effectively adapt to the deformation trajectory of the arc-shaped pressure plate 4 during the deformation process. At the same time, after the deformation of the arc-shaped pressure plate 4 is completed, the three deformation notches 5 can reach the maximum deformation amount in sequence to ensure that the corners of the arc-shaped pressure plate 4 remain highly stable, and at the deformation notches 5 with the largest volume, the deformation amount of the arc-shaped pressure plate 4 reaches the maximum to further ensure the smoothness of its deformation process.

[0030] The overall cross-section of the positioning seat 6 is semicircular, with an arc-shaped top and a flat bottom. The overall trajectory of the arc groove 7 is arc-shaped, and is closed in a semicircular form at the top of the arc, and an involute-shaped notch is formed between the bottom end and the positioning seat 6 and the limiting block 8. Both sides of the limiting block 8 are arc-shaped trajectories. The inner and outer arc trajectories of the limiting block 8 are relatively distributed. The convex part of the inner arc trajectory of the limiting block 8 and the concave part of one side of the inner wall of the arc groove 7 are maintained in opposite distribution. By using the above-mentioned arrangement, it is ensured that the limiting block 8 can gradually move toward the involute-shaped notch position of the arc groove 7 during the deformation process, thereby providing it with sufficient deformation space, ensuring that the spacing between the limiting block 8 and the arc groove 7 meets the lateral distance difference generated by the arc pressure plate 4 when it is twisted, and ensuring the overall structural strength of the positioning seat 6.

[0031] The bottom end surface of the limiting block 8 and the bottom end surface of the positioning seat 6 are maintained in the same horizontal plane.

[0032] The deformation slot 5 is in the shape of a wedge slot as a whole, and the inclination angles of the multiple deformation slots 5 change synchronously with the trajectory of the arc pressure plate 4. The above-mentioned setting can ensure that the deformation slot 5 can adapt to the curved trajectory of the arc pressure plate 4 in both the idle state and the working state of the arc pressure plate 4, so as to ensure the controllability of its overall structure in the deformation direction, thereby increasing the reliability of its overall structure.

[0033] Velcro is respectively attached to the inner and outer sides of both sides of the restraint belt 1, and the two side tracks of the limiting block 8 together form a teardrop-shaped structure. The two side tracks of the limiting block 8 are connected at the end and maintain a seamless connection. By utilizing the above-mentioned arrangement, the convenience of the restraint belt 1 during winding and binding can be increased by Velcro, and the overall track of the limiting block 8 is used to form a teardrop-shaped structure, so that when it comes into contact with the patient's skin during the twisting process, the irritation to the patient's skin is minimized, thereby ensuring its softness during deformation. At the same time, when the limiting block 8 reaches the maximum deformation, its teardrop-shaped outer track and the arc groove 7 still maintain a certain degree of mobility, so that the two structures will not be locked after contacting each other, thereby further increasing the flexibility between the limiting block 8 and the positioning seat 6.

[0034] For details, please refer to the attached manual Figure 3 The overall side surface of the arc-shaped pressing plate 4 is a sheet-like structure, and the arc-shaped pressing plate 4 is made of a highly elastic material.

[0035] The specific implementation method is as follows: the arc-shaped pressure plate 4 is in a sheet-like structure as a whole, so that after deformation and compression, it can uniformly compress the puncture site of the patient from point to surface to stop bleeding, thereby reducing the complications caused by congestion and local swelling caused by irregular hemostasis, and improving the safety of its structure in constrained hemostasis.

[0036] For details, please refer to the attached manual Figure 6 The semicircular pressing block 9 is in an arc shape as a whole, and the arc vertex of the semicircular pressing block 9 and the vertex of the positioning seat 6 are symmetrical to each other and are located on the same horizontal line.

[0037] The specific implementation method is as follows: the arc vertex of the semicircular pressure block 9 and the vertex of the positioning seat 6 are symmetrically arranged so that after the arc pressure plate 4 is compressed and deformed, the vertices between the semicircular pressure block 9 and the positioning seat 6 can contact each other, and ensure that the vertex of the semicircular pressure block 9 applies pressure to the positioning seat 6 as a whole, thereby continuously maintaining the stability and reliability of the positioning seat 6, and preventing it from tilting up after being pressed by the side of the arc pressure plate 4, thereby causing the problem of tipping over.

[0038] Working principle of the present invention:

[0039] Step 1: First, the operator assembles the various components of the device normally, and then uses the device normally.

[0040] Step 2: First, place the positioning seat 6 on one side of the puncture point (site), and ensure that the positioning seat 6 is located on the opposite side of the puncture direction (for example, if the puncture needle is attached to the skin and punctured from right to left, the positioning seat 6 is placed in the leftmost position after the puncture needle is inserted, and vice versa). Then the medical staff wraps the restraint belt 1 around the patient's trunk at the puncture site (generally, cardiac interventional surgery is performed from the blood vessels at the arm), and continues to wrap and tighten the restraint belt 1 (the winding method and process of the restraint belt 1 can refer to the existing medical standards and will not be further described). (a step will be omitted), at this time, the arc-shaped pressing plate 4 is gradually pressed down under the winding and tightening operation of the restraining belt 1, and begins to expand outward from the middle, and gradually deforms in a C-shaped shape as a whole. At the same time, during the deformation process, a plurality of deformation notches 5 provided on the arc-shaped pressing plate 4 will shrink along the deformation trajectory of the arc-shaped pressing plate 4, thereby adapting to the deformation trend of the arc-shaped pressing plate 4, ensuring that the arc-shaped pressing plate 4 is compressed and deformed in a predetermined folding shape, providing directionality for its deformation process, and at the same time, during the deformation process, the arc-shaped pressing plate 4 gradually deforms from left to right. The compression track and direction are relative to the puncture track and direction, so that the puncture site is gradually pressed from the inside to the outside, and the internal bleeding point is fully pressed to the bleeding point on the surface of the skin. The pressure from the deep layer of the puncture site to the surface of the skin constrains the direction of hemostasis, which can effectively avoid adverse conditions such as congestion during the pressing process. In addition, the bottom end of the arc-shaped pressure plate 4 will continue to compress the limiting block 8 on one side of the positioning seat 6, causing it to gradually deform and twist toward one side of the arc-shaped groove 7. Until the limiting block 8 is against the inner wall surface of the arc groove 7, and the semicircular pressure block 9 and the apex between the positioning seat 6 are in contact with each other, and the positioning seat 6 is pressed as a whole through the semicircular pressure block 9, at this time, one half of the arc pressure plate 4 is completely attached and pressed on the puncture site of the patient's torso, and is maintained in a flat state under the influence of continuous pressure, and the other half shows an extreme twisting tendency. At this point, the deformation process is completed, and the purpose of compression hemostasis is achieved. Finally, the device completes the constrained hemostasis treatment process for the patient's puncture site.

[0041] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.

[0042] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships.

In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other;
