Description

Technical Field

[0001] The utility model relates to the field of medical instruments, and more specifically to a novel distal radial artery compression hemostat. Background Art

[0002] At present, 90% of percutaneous coronary angiography / intervention in China is completed through the traditional radial artery approach. Related complications such as hand swelling (occurring in most patients), radial artery spasm, radial artery occlusion (incidence of about 1% to 30%), hematoma, pseudoaneurysm, arteriovenous fistula, etc. have attracted the attention of doctors and patients.

[0003] In 2021, the <<Chinese Expert Consensus on Percutaneous Coronary Intervention via the Distal Radial Artery>> was released, suggesting that operators with certain puncture experience can use the distal radial artery as the main option for percutaneous coronary intervention. Distal radial artery puncture is a new puncture technique for coronary intervention, and the puncture site is the dorsal side of the hand (Hegu acupoint area or snuff bottle area). The distal radial artery in this area is a branch of the radial artery, which is relatively thick and fixed, and is located at the proximal end of the thumb artery. Puncture at this site can greatly reduce the incidence of bleeding and hematoma in patients, and reduce the risk of proximal radial artery occlusion and radial nerve injury. In addition, thanks to the abundant blood supply to the superficial and deep palmar arches, the blood supply to the thumb will not be affected even if complications of radial artery occlusion occur. Not only that, during the postoperative compression period, the patient's hand can always be in a functional position (natural resting state), the postoperative wound hemostasis is fast, the bandaging time is short, and there is almost no swelling, pain, or numbness in the hand, which greatly increases the patient's comfort and tolerance for surgery. Studies in recent years have shown that distal radial artery puncture accounts for about 24% to 44% of coronary interventions. Compared with traditional radial artery puncture, distal radial artery puncture has fewer complications, and the incidence of radial artery occlusion is only 0% to 0.9%.

[0004] However, there is currently no mature compression hemostat specifically for the distal radial artery. Most clinical methods choose to wrap an elastic bandage several times or use the "8" method to fix it. This method makes it difficult to adjust the compression force in the puncture area. On the other hand, most existing conventional radial artery compression hemostat uses tape to adhere to the patient's skin. When fixing the compressor to the user's hand, the tightness needs to be adjusted according to the shape and size of the hand. If the compression position is not suitable, it needs to be disassembled and readjusted. After multiple disassembly, the viscosity of the tape will be greatly reduced, and the compressor cannot be firmly fixed. In extreme cases, it is even necessary to replace the radial artery compression hemostat as a whole. Utility Model Content

[0005] Aiming at the above defects of the prior art, the utility model provides a novel distal radial artery compression hemostat.

[0006] The technical solution adopted by the utility model to solve its technical problems is: constructing a novel distal radial artery compression hemostat, the compressor comprising a triangular base plate, a threaded hole arranged in the middle of the base plate, a stud passing through the threaded hole and screwed with the threaded hole, a pressure plate fixed at the first end of the stud, a knob fixed at the second end of the stud, and a plurality of connection belts connected to each side of the base plate and used for positioning the compressor, each of the connection belts having a Velcro tape on the front and back sides of the distal end, a wedge-shaped elastic pad on the bottom surface of the pressure plate, and the bottom surface of the elastic pad gradually protrudes from the edge to the middle to form a spherical arc shape.

[0007] In the novel distal radial artery compression hemostat described in the utility model, the connecting bands are respectively a first connecting band connected to the first side edge of the substrate, a second connecting band connected to the second side edge of the substrate, and a third connecting band connected to the third side edge of the substrate, the front and back sides of the distal end of the first connecting band are respectively provided with a first bristle surface Velcro and a first round fur surface Velcro, the front and back sides of the distal end of the second connecting band are respectively provided with a second bristle surface Velcro and a second round fur surface Velcro, and the front and back sides of the distal end of the third connecting band are respectively provided with a third bristle surface Velcro and a third round fur surface Velcro.

[0008] In the novel distal radial artery compression hemostat described in the utility model, a first side edge of the base plate is provided with a first arcuate groove, and the proximal end of the first connecting belt is connected to the first arcuate groove and can slide in the first arcuate groove.

[0009] In the novel distal radial artery compression hemostat described in the utility model, the arc length of the first arc-shaped groove is greater than the proximal width of the first connecting band.

[0010] In the novel distal radial artery compression hemostat described in the utility model, the second side edge of the base plate is provided with a second arcuate groove, and the proximal end of the second connecting belt is connected to the second arcuate groove and can slide in the second arcuate groove.

[0011] In the novel distal radial artery compression hemostat described in the utility model, the arc length of the second arc-shaped groove is greater than the proximal width of the second connecting band.

[0012] In the novel distal radial artery compression hemostat described in the utility model, a third arcuate groove is provided on the third side of the base plate, and the proximal end of the third connecting belt is connected to the third arcuate groove and can slide in the third arcuate groove.

[0013] In the novel distal radial artery compression hemostat described in the utility model, the arc length of the third arc-shaped groove is greater than the proximal width of the third connecting band.

[0014] In the novel distal radial artery compression hemostat described in the utility model, the first connecting band, the second connecting band and the third connecting band are all elastic bands.

[0015] The implementation of the novel distal radial artery compression hemostat of the utility model has the following beneficial effects: when using the distal radial artery compression hemostat of the utility model, the base plate can be placed at the position of the radial artery on the back of the hand, so that the wedge-shaped elastic pad at the bottom of the pressure plate is located in the Hegu acupoint area or the snuff bottle area, and the shape of the wedge-shaped elastic pad fits the anatomical shape of the distal radial artery, while reducing unnecessary compression on the extensor pollicis longus tendons and the extensor index finger tendons on both sides, improving the patient's comfort and experience. After the connecting belt is fixed to the corresponding position of the hand, the rotating knob drives the pressure plate to approach the distal radial artery puncture position to achieve precise compression and hemostasis of the radial artery. During use, the pressure of the pressure plate can be adjusted by rotating the stud to meet the pressure requirements of the distal radial artery compression and hemostasis at different stages. The Velcro is easy to disassemble and can be used repeatedly, which is convenient for adjustment and fixation according to the shape and size of the user's hand, so that the compressor can be firmly and reliably fixed to the user's hand.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, in the first embodiment of the novel distal radial artery compression hemostat of the utility model, the compressor 10 includes a triangular base plate 11, a threaded hole 12 arranged in the middle of the base plate 11, a stud 13 passing through the threaded hole 12 and screwed with the threaded hole 12, a pressing plate 14 fixed to the first end of the stud 13, a knob 15 fixed to the second end of the stud 13, and a plurality of connecting belts connected to each side of the base plate 11 and used to position the compressor, and each connecting belt is provided with Velcro on the front and back of the distal end. The pressing plate 14 can be a disc-shaped pressing plate, and the bottom surface of the disc-shaped pressing plate 14 is provided with a wedge-shaped elastic pad 141, and the bottom surface of the elastic pad 141 gradually bulges from the edge to the middle to form a spherical arc shape.

[0022] Optionally, the connecting belts are respectively a first connecting belt 16 connected to the first side edge of the substrate 11, a second connecting belt 17 connected to the second side edge of the substrate 11, and a third connecting belt 18 connected to the third side edge of the substrate 11, and the front and back sides of the distal ends of the first connecting belt 16 are respectively provided with a first spurred surface Velcro 19 and a first round fleece surface Velcro, the front and back sides of the distal ends of the second connecting belt 17 are respectively provided with a second spurred surface Velcro 20 and a second round fleece surface Velcro, and the front and back sides of the distal ends of the third connecting belt 18 are respectively provided with a third spurred surface Velcro 21 and a third round fleece surface Velcro.

[0023] When using the distal radial artery compression hemostat of the utility model, the base plate 11 can be placed at the position of the radial artery on the back of the hand, and the wedge-shaped elastic pad 141 at the bottom of the pressure plate 14 can be placed in the Hegu acupoint area or the snuff bottle area. The first connecting belt 16 is wound from the base of the thumb to the palm, the second connecting belt 17 is wound from the tail edge of the little finger to the palm, and the third connecting belt 18 is wound from the tail edge of the thumb to the palm, and the first Velcro 19 with the second Velcro with the round Velcro is bonded, and the second Velcro 20 with the third Velcro with the round Velcro is used to fix the distal ends of the first connecting belt 16, the second connecting belt 17 and the third connecting belt 18, so that the compressor can be reliably positioned and fixed to the hand. Then the knob 15 is rotated to drive the pressure plate 14 to approach the distal radial artery, so as to achieve accurate compression of the distal radial artery. When the compressor 10 needs to be released, it is only necessary to loosen the Velcro at the distal ends of the first connecting belt 16, the second connecting belt 17 and the third connecting belt 18 to achieve the release. When the compressor 10 is compressed again, it is only necessary to bond the Velcro at the distal ends of the first connecting belt 16, the second connecting belt 17 and the third connecting belt 18 to achieve the fixation of the compressor 10. It is understandable that the burr surface on the first connecting belt 16, the second connecting belt 17 and the third connecting belt 18 can also be bonded with the round Velcro after the connecting belt passes around the positioning part of the hand to achieve the positioning and fixation of the compressor.

[0024] The size of the wedge-shaped elastic pad 141 can be adapted to the Hegu point or the snuff bottle area, and the elastic pad 141 fully fits the anatomical shape of the distal radial artery, which is conducive to accurate hemostasis of the distal radial artery. In addition, this design can reduce unnecessary compression of the compressor on the extensor pollicis longus tendon and the extensor index finger tendon on both sides, improving the patient's comfort and experience. The wedge-shaped elastic pad 141 can be made of silicone or other materials with suitable flexibility, and there is no excessive restriction here.

[0025] In this embodiment, the first side edge of the base plate 11 is provided with a first arcuate groove 22, and the proximal end of the first connecting belt 16 is connected to the groove wall of the first arcuate groove 22 and can slide in the first arcuate groove 22. The first arcuate groove 22 allows the first connecting belt to move in a limited manner along the circumferential direction relative to the first side edge of the base plate 11, so as to adapt to palms of different sizes and achieve good fixation of the compressor.

[0026] Specifically, the arc length of the first arc-shaped groove 22 is greater than the proximal width of the first connecting belt 16 .

[0027] When fixing the first connecting belt 16, the first connecting belt 16 in the first arc groove 22 can be slid. Since the first connecting belt 16 can move circumferentially to a limited extent relative to the first side edge of the base plate 11, it can adapt to palms of different sizes and achieve good fixation of the compressor.

[0028] Likewise, a second arc-shaped groove 23 is formed on the second side of the base plate 11 , and a proximal end of the second connecting belt 17 is connected to the second arc-shaped groove 23 and can slide in the second arc-shaped groove 23 .

[0029] Specifically, the arc length of the second arc-shaped groove 23 is greater than the proximal width of the second connecting belt 17 .

[0030] When the second connecting belt 17 is fixed, the second connecting belt 17 in the second arc groove 23 can be slid, so as to adjust the angle of the second connecting belt 17 .

[0031] Likewise, a third arc-shaped groove 24 is formed on the third side of the base plate 11 , and a proximal end of the third connecting belt 18 is connected to the third arc-shaped groove 24 and can slide in the third arc-shaped groove 24 .

[0032] Specifically, the arc length of the third arc-shaped groove 24 is greater than the proximal width of the third connecting band 18 .

[0033] When the third connecting belt 18 is fixed, the third connecting belt 18 in the third arc groove 24 can be slid, so as to adjust the angle of the third connecting belt 18 .

[0034] Preferably, in order to achieve a better compression effect, the first connecting belt 16, the second connecting belt 17 and the third connecting belt 18 are all elastic belts.

[0035] Compared with the prior art, the utility model provides a wedge-shaped elastic pad at the bottom of the pressure plate, and the shape of the wedge-shaped elastic pad fits the anatomical shape of the distal radial artery, which is conducive to accurate hemostasis of the distal radial artery, while reducing unnecessary compression on the extensor pollicis longus tendon and the extensor index finger tendon on both sides, improving the patient's comfort and experience. The compressor is fixed by an elastic connecting belt with Velcro, which is easy to disassemble and adjust the fixed position, and can be used repeatedly, and is easy to adjust and fix according to the shape and size of the user's hand, so that the compressor can be firmly and reliably fixed to the user's hand.

[0036] In addition, in the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", "stacked" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
