Description

Technical Field

[0001] The utility model relates to the technical field of hemostats, in particular to a distal radial artery puncture hemostat. Background Art

[0002] Currently, transradial artery access (TRA) is the recommended approach for coronary artery intervention. TRA has a high overall safety profile, and radial artery occlusion (RAO) is its most common complication, which has an adverse effect on patients who require multiple interventional treatments. Distal radial artery access (DRA) has emerged as a promising alternative approach that can minimize the risk of RAO. A hemostat is a medical device used after distal radial artery puncture. It is mainly used to quickly stop bleeding after arterial puncture to prevent vascular bleeding and reduce the patient's bleeding risk. This type of hemostat consists of a pressure device, a hemostatic pad, a fixation belt or clamp, and external protection. Its structural design is simple and effective: the pressure device applies appropriate pressure on the puncture point through an adjustable mechanism, prompting the blood vessel to close and form a thrombus; the hemostatic pad absorbs blood and keeps it dry, and the fixing strap or clip ensures that the hemostat is firmly fixed on the patient. However, during use, the current hemostat may cause the hemostatic pad to shift from the puncture site due to the softness of its own material and the uncontrolled bending movement of the user's thumb. At this time, the area where pressure should be applied may not receive effective pressure, resulting in incomplete closure of the blood vessel or insufficient thrombus formation. In this case, the blood vessel may continue to bleed, and further hemostatic measures are required, which increases the patient's pain and discomfort and prolongs the treatment time. Utility Model Content

[0003] The purpose of the utility model is to provide a distal radial artery puncture hemostat, which adds a movable extractable pressure plate on the upper surface of an integrally formed extensor wrist support belt and a thumb support belt. When the extensor wrist support belt and the thumb support belt are worn to the user's base of the thumb through a double-belt edge tightening structure and the thumb support belt, the distal radial artery puncture point is compressed by a silicone hemostatic pad, and the deformation of the support belt and the influence of the user's thumb movement are reduced by the pressure plate, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a distal radial artery puncture hemostat, comprising an extensor wrist support strap and a thumb support strap integrally formed at one end of the extensor wrist support strap for being worn on the same thumb, an elastic band being sewn on the lower surface of the thumb support strap, and double-band edge tightening structures for being worn on the same wrist being installed on both sides of the extensor wrist support strap, a tiger's mouth wing plate being provided on the front and rear sides of the extensor wrist support strap, a silicone hemostatic pad being installed on the lower surface of the tiger's mouth wing plate, and a pressure plate sleeve being movably placed being sewn on the upper surfaces of the extensor wrist support strap and the thumb support strap.

[0005] Preferably, the silicone hemostatic pad is made of transparent medical silicone material.

[0006] Preferably, the double-banded tightening structure includes a hook surface tightening band and a fleece surface tightening band installed on the front and rear side edges of the top end of the extensor carpal retinaculum support band. The upper surface of the hook surface tightening band is provided with a felt surface for adhesively bonding with the fleece surface tightening band.

[0007] Preferably, the silicone hemostatic pad is slidably installed inside the extensor carpal retinaculum support band. A straight opening hollow groove for the left and right sliding of the silicone hemostatic pad is provided inside the extensor carpal retinaculum support band. Locking edges are provided on both sides of the top end and both sides of the bottom end of the silicone hemostatic pad, and the locking edges are used for the interference fit sliding between the extensor carpal retinaculum support band and the silicone hemostatic pad.

[0008] Preferably, one end of the movable placement pressure plate sleeve close to the thumb support band is provided with a Z-shaped bending edge extending obliquely upward, and a drawable pressure plate is built into the movable placement pressure plate sleeve.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the movable and drawable pressure plate, on the one hand, the structural rigidity and stability of the thumb support band and the extensor carpal retinaculum support band are enhanced, and on the other hand, the influence of the user's thumb movement is reduced. In this way, the deformation of the extensor carpal retinaculum support band and the thumb support band is effectively reduced, and the stable position of the silicone hemostatic pad above the puncture point is maintained, thereby ensuring the continuous pressure applied to the puncture point. At this time, the pressure plate can ensure that the silicone hemostatic pad is always in full contact with the puncture point and maintains an appropriate pressure, which is beneficial to the closure of blood vessels. This design can significantly reduce the situation where the expected hemostatic effect cannot be achieved and avoid the rebleeding of blood vessels caused by the displacement of the silicone hemostatic pad; the pressure plate can be flexibly taken out and has the function of reuse.

Detailed implementation manner

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-5 , an embodiment provided by the present invention: A far radial artery puncture hemostat, including an extensor wrist support band 1 and a thumb support band 2 integrally formed at one end of the extensor wrist support band 1 for wearing with the thumb. An elastic band 5 is sewn on the lower surface of the thumb support band 2. Double-band edge tightening structures 6 for wearing with the wrist are installed on both sides of the extensor wrist support band 1. Thenar wing plates 3 are provided on the front and rear sides of the extensor wrist support band 1. A silicone hemostatic pad 4 is installed on the lower surface of the thenar wing plate 3. A movable placement pressure plate sleeve 7 is sewn on the upper surfaces of the extensor wrist support band 1 and the thumb support band 2;

[0018] The silicone hemostatic pad 4 has a higher softness, can better fit the skin surface of the patient, reduce skin friction and discomfort, and improve the treatment comfort of the patient. The silicone hemostatic pad 4 is made of transparent medical silicone material. The transparent structure of the silicone hemostatic pad 4 can help the staff observe whether the puncture point is closed and whether the hemostatic effect is feasible;

[0019] A washer with a hardness higher than that of the silicone hemostatic pad 4 is provided at the edge position at the bottom end of the silicone hemostatic pad 4. At this time, the silicone hemostatic pad 4 is in direct contact with the skin, and the washer is located at the edge of the silicone hemostatic pad 4, playing a role in pressing the skin;

[0020] The double-band edge tightening structure 6 includes a hook surface tightening band 601 and a Velcro surface tightening band 602 installed on the front and rear sides of the top end of the extensor wrist support band 1. A felt surface 603 for bonding with the Velcro surface tightening band 602 is provided on the upper surface of the hook surface tightening band 601. The elastic band 5 can quickly tighten and connect the thumb support band 2 with the user's thumb, ensuring the stable wearing of the thumb support band 2. When the extensor wrist support band 1 is connected with the user's wrist, the hook surface tightening band 601 and the Velcro surface tightening band 602 are wound around the user's wrist, and the overlapping degree of the hook surface tightening band 601 and the Velcro surface tightening band 602 is adjusted to control the pressure of the extensor wrist support band 1 and the pressure plate on the user, ensuring the continuous pressure exerted by the silicone hemostatic pad 4 on the puncture point;

[0021] The silicone hemostatic pad 4 is slidably installed inside the extensor wrist support band 1. There is a straight opening hollow groove inside the extensor wrist support band 1 for the left - right sliding of the silicone hemostatic pad 4. On both sides of the top and bottom of the silicone hemostatic pad 4, there are hemming edges, which are used to make the extensor wrist support band 1 and the silicone hemostatic pad 4 have an interference sliding fit. The silicone hemostatic pad 4 is made of medical - grade silicone, which will not cause skin allergies or other adverse reactions and has no side - effects on the health of patients. The slidably arranged silicone hemostatic pad 4 can be flexibly selected for the left or right side, enabling the hemostat to be applicable to both the left and right hands without the need to select separately for each hand;

[0022] One end of the pressure plate close to the thumb support band 2 is provided with a Z - shaped bending edge 701 extending obliquely upward. The setting of the Z - shaped bending edge 701 allows a certain degree of movement of the thumb part at the thumb support band 2, that is, a certain amount of movement margin is reserved. The pressure plate is made of aluminum alloy. As a material, aluminum alloy has excellent strength and hardness, and can effectively resist deformation and the influence of external forces. In the pressure plate part of the hemostat, this material selection can significantly enhance the structural stability and durability of the hemostat, ensuring that the hemostat can maintain its shape and function integrity for a long time during use; It can be arbitrarily extracted according to needs, which is conducive to recycling.

[0023] Embodiment 2, based on Embodiment 1, is given by Figure 1 and Figure 5 A transparent hemostat body 8 is installed at the top of the silicone hemostatic pad 4. Through the hemostat body 8, the pressure contact situation between the silicone hemostatic pad 4 and the user's skin is further adjusted. A break - off part for the left - right sliding of the hemostat body 8 and the silicone hemostatic pad 4 is also provided on the surface of the pressure plate to enable the normal movement of the silicone hemostatic pad 4 and the hemostat body 8.

[0024] When the embodiment of the present application is in use, first, the user takes out the hemostat, and wears the extensor wrist support band 1 and the thumb support band 2 on the user's wrist and the thenar of the user's thumb respectively until the thumb support band 2 covers the nail part of the thumb. The elastic band 5 makes the thumb support band 2 closely fit the user's thumb and keeps a certain wearing pressure between the thumb support band 2 and the thumb. At this time, the silicone hemostatic pad 4 on the lower surface of the thenar wing plate 3 covers the puncture point of the distal radial artery. Subsequently, the staff uses the double-band edge tightening structure 6 to continuously tighten the extensor wrist support band 1, so that the extensor wrist support band 1 tightly wraps around the user's wrist. At this time, the thenar wing plate 3 and the silicone hemostatic pad 4 exert a pressing force on the puncture point of the distal radial artery to make the silicone hemostatic pad 4 closely fit the distal radial artery puncture point. When the hemostat is worn, the pressure plate is located on the extension line of the extensor wrist support band 1, the thumb support band 2 and the thumb. On the one hand, it enhances the structural rigidity and stability of the thumb support band 2 and the extensor wrist support band 1. On the other hand, it reduces the influence of the user's thumb movement, thereby effectively reducing the deformation of the extensor wrist support band 1 and the thumb support band 2 and keeping the silicone hemostatic pad 4 in a stable position above the puncture point, so as to ensure the continuous pressure applied to the puncture point. At this time, the pressure plate can ensure that the silicone hemostatic pad 4 always makes full contact with the puncture point and maintains an appropriate pressure, which is beneficial to the closure of blood vessels. This design can significantly reduce the situation where the expected hemostatic effect cannot be achieved and avoid rebleeding of blood vessels caused by the displacement of the silicone hemostatic pad 4.
