Description

Technical Field

[0001] This invention relates to the field of medical hemostatic devices, specifically to a distal radial artery fixation and compression hemostatic device. Background Technology

[0002] Distal radial artery puncture is a newly emerging puncture procedure. The puncture site is the angle between the extensor pollicis brevis and extensor pollicis longus tendons, commonly known as the "snuff bottle area." After the distal radial artery puncture in the snuff bottle area, significant bleeding often occurs at the puncture site. Therefore, it is necessary to apply pressure to the bleeding point to stop the bleeding. When medical staff use traditional radial artery compression hemostats to stop the bleeding, the snuff bottle area differs from the conventional radial artery in location, having a certain inclination, making it prone to slippage and thus unable to effectively stop the bleeding. If the doctor simply uses gauze to wrap and fix the puncture point in the snuff bottle area without adjusting the pressure, the pressure may be too high or too low, resulting in unsatisfactory hemostasis. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a distal radial artery fixation and compression hemostasis device, which solves the problem that existing compression devices cannot achieve hemostasis due to unstable compression force at the distal radial artery puncture point.

[0004] To achieve the above-mentioned technical effects, the technical solution adopted by the present invention is as follows:

[0005] A distal radial artery fixation and compression hemostasis device, comprising:

[0006] A fixing ring is used to fix it on the patient's wrist. The fixing ring includes a first half ring, a second half ring, a first fixing frame, and a second fixing frame. One end of the first half ring and the second half ring are hinged together, and the other end of the first half ring and the second half ring are snapped together. The first fixing frame is fixedly disposed on the outer side of the first half ring, and the second fixing frame is fixedly disposed on the outer side of the second half ring. The first fixing frame and the second fixing frame are arranged vertically opposite each other.

[0007] A ring band assembly, wherein the two ends of the ring band are respectively fixed to the thumb and index finger, and the middle part of the ring band assembly covers the web between the thumb and index finger of the palm; and

[0008] The pressure regulating band assembly has one end slidably connected to the top side of the fixing ring, and the other end slidably connected to the bottom side of the fixing ring after passing around the finger ring band assembly. The pressure regulating band assembly includes a compression band and a compression member. One end of the compression band extends from the back of the patient's palm, passes through the first fixing frame, and is snapped in place. The other end of the compression band passes around the finger ring band assembly, extends from the center of the patient's palm, passes through the first fixing frame, and is snapped in place. A puncture hole is provided on the compression band, and the bottom end of the compression member passes through the puncture hole to apply pressure to the puncture point.

[0009] The aforementioned distal radial artery fixation and compression hemostasis device is fitted onto the patient's wrist with a fixing ring to secure both ends of the pressure regulating band assembly, preventing the pressure column from sliding. Simultaneously, the movement of the pressure column is adjusted so that it is positioned above the puncture point and aligned with it. The pressure applied to the puncture point is adjusted by the pressure column to achieve the desired hemostasis effect. The finger ring band assembly supports the connecting band and also protects the skin at the base of the thumb on the palm.

[0010] Furthermore, the outer side of the first half-ring away from the hinge end is provided with a locking post, and the locking post has multiple vertically arranged locking balls along the axial direction. The outer side of the second half-ring away from the hinge end is provided with a locking block, and the locking block has a locking hole. A locking ring is provided in the locking hole. Both the locking ring and the locking balls are made of elastic material. The diameter of the locking ball is the same as the diameter of the locking hole, and the diameter of the locking ball is larger than the inner diameter of the locking ring. The locking post can be inserted into the locking hole and locked into the locking block. By inserting the locking post into the locking hole, the locking ring is locked between two adjacent locking balls, thereby adjusting the locking size of the fixing ring according to the thickness of the patient's wrist.

[0011] Furthermore, the finger band assembly includes an index finger ring, a thumb ring, and a finger strap, with the index finger ring and thumb ring respectively positioned at both ends of the finger strap. By looping the index finger ring and thumb ring onto the patient's index finger and thumb respectively, the finger strap supports the connecting band, while simultaneously protecting the skin at the base of the thumb and forefinger of the palm.

[0012] Furthermore, the compression band includes a first fixing band, a second fixing band, and a connecting band. The connecting band is elastic, and its two ends are fixedly connected to the first and second fixing bands, respectively. A puncture hole is provided on the connecting band, and a connecting ring is fitted inside the puncture hole. The bottom end of the compression member passes through the puncture hole to apply pressure to the puncture point. The end of the first fixing band away from the connecting band passes through the first fixing frame and is inserted into it. The end of the second fixing band away from the connecting band passes through the second fixing frame and is inserted into it. By inserting the ends of the first fixing band and the second connecting band into the first and second fixing frames respectively and engaging them, the length of the compression band passing through the first and second fixing frames can be adjusted, thereby aligning the bottom end of the compression member with the puncture point for compression and hemostasis.

[0013] Furthermore, the end of the first fixing strap away from the connecting strap is provided with an oblique tooth, and the side of the first fixing frame away from the first half-ring has a through snap hole with a snap button. One side of the snap button is hinged to one side of the snap hole, and the bottom surface of the snap button has an inclined snap tooth that can engage with the oblique tooth on the first fixing strap inserted into the first fixing frame. By interlocking the snap tooth with the oblique tooth on the first fixing strap, the first fixing strap is thus engaged with the first fixing frame.

[0014] Furthermore, a snap-on groove is provided on the side of the first fixing frame away from the first semi-ring, and the snap-on groove communicates with the snap-on hole. A snap-on block is provided on the side of the snap key away from the hinge edge, and both sides of the snap-on block are provided with protruding pads. The snap key is fastened into the snap-on groove through the snap-on block and connected to the first fixing frame. By fastening the snap-on block into the snap-on groove, the snap key can be fixed on the first fixing frame, preventing the snap key from detaching from the first fixing frame and causing the snap-on teeth to fail to engage the end of the first fixing band.

[0015] Furthermore, the second fixing band has straight teeth at its end away from the connecting band, and the second fixing frame has a T-shaped first slot on its side away from the second half-ring. A through-hole second slot is opened on the outer side of the sidewall of the second fixing frame. The second slot is perpendicular to and communicates with the first slot. A second insert is inserted into the second slot, with a toothed end near the second half-ring that engages with the end of the second fixing band away from the connecting band. A first insert is inserted into the first slot to cover the end of the second insert that is away from and near the second half-ring. The second fixing band and the second fixing frame are thus interlocked by the interlocking of the end of the second insert with the straight teeth on the first fixing band.

[0016] Furthermore, the compression component includes a compression column and a compression hemisphere. The compression column has external threads on its outer side and internal threads on its inner side. The bottom end of the compression column can be threaded into the connecting ring and extends to the outer side of the connecting ring. The compression hemisphere is located at the bottom end of the compression column, and its bottom surface is flat. By rotating the compression column, it is slowly pressed against the puncture point. The pressure of the compression hemisphere on the puncture point is adjusted to achieve hemostasis.

[0017] Furthermore, the bottom of the connecting ring is equipped with a snap-fit ​​cover. The bottom of the snap-fit ​​cover can cover the area around the puncture point, allowing for pre-positioning of the puncture point and improving accuracy.

[0018] The beneficial effects of this invention are as follows: This distal radial artery fixation and compression hemostasis device uses a first fixing band and a second fixing band to be inserted into the first fixing frame and the second fixing frame respectively, so that the compression column is moved above the puncture point. The fixing ring is placed on the patient's wrist to fix both ends of the pressure adjustment band assembly, preventing the compression column from sliding. The pressure on the puncture point is adjusted by the compression column to achieve the ideal hemostasis effect. The finger ring band assembly supports the connecting band and protects the skin at the base of the thumb and forefinger. Moreover, the snap-fit ​​cover can position the puncture point so that the compression hemisphere can accurately press on the puncture point, improving accuracy. Attached Figure Description

Detailed Implementation

[0028] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific way. Therefore, they should not be construed as limitations on this invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] Please see Figure 1 The present invention provides a distal radial artery fixation and compression hemostasis device, comprising a fixing ring 10, a finger ring assembly 30, and a pressure regulating band assembly 20. The fixing ring 10 is used to fix the device on the patient's wrist and fix both ends of the pressure regulating band assembly 20. The two ends of the finger ring assembly 30 are respectively fixed on the thumb and index finger. The middle part of the finger ring assembly 30 covers the web between the thumb and index finger of the palm, preventing the pressure regulating band assembly 20 from directly constricting the skin of the web between the thumb and index finger, while providing support for the middle part of the finger ring assembly 30. One end of the pressure regulating band assembly 20 is slidably connected to the top side of the fixing ring 10, and the other end passes around the finger ring assembly 30 and is slidably connected to the bottom side of the fixing ring 10. The pressure regulating band assembly 20 includes a compression band 21 and a compression member 22. The compression band 21 has a puncture hole, and the bottom end of the compression member 22 passes through the puncture hole to compress the puncture point. By sliding the two ends of the compression band 21 to the top and bottom sides of the fixing ring 10 respectively, the length of the compression band 21 can be adjusted, so that the puncture hole on the compression band 21 is moved above the puncture point. By pressing the bottom end of the compression member 22 on the puncture point, the pressure of the compression member 22 on the puncture point can be adjusted, thereby achieving a better hemostasis effect.

[0032] Please refer to the following: Figure 2The fixing ring 10 includes a first half ring 11, a second half ring 12, a first fixing frame 13, and a second fixing frame 14. One end of the first half ring 11 and the second half ring 12 are hinged together, and the other end of the first half ring 11 and the second half ring 12 are snapped together. The first fixing frame 13 is fixedly disposed on the outer side of the first half ring 11, and the second fixing frame 14 is fixedly disposed on the outer side of the second half ring 12. The first fixing frame 13 and the second fixing frame 14 are arranged vertically opposite each other.

[0033] Specifically, the outer side of the first half-ring 11 away from the hinge end is provided with a locking post 111, and the locking post 111 is provided with a plurality of vertically arranged locking balls 112 along the axial direction. The outer side of the second half-ring 12 away from the hinge end is provided with a locking block 121, and the locking block 121 is provided with a locking hole 122. The locking hole 122 is provided with a locking ring 123. Both the locking ring 123 and the locking balls 112 are made of elastic material. The diameter of the locking ball 112 is the same as the diameter of the locking hole 122, and the diameter of the locking ball 112 is larger than the inner diameter of the locking ring 123. The locking post 111 can be inserted into the locking hole 122 and locked into the locking block 121, so that the locking ring 123 is locked between two adjacent locking balls 112, thereby locking the locking post 111 in the locking block 121, so that the locking post 111 cannot continue to slide. The inner surfaces of the first half-ring 11 and the second half-ring 12 are provided with elastic pads 15 to prevent the inner surfaces of the first half-ring 11 and the second half-ring 12 from directly contacting the skin, thereby protecting the skin and making the skin feel comfortable.

[0034] Since the wrists of different patients are of different thicknesses, the wrist is placed between the first half ring 11 and the second half ring 12, so that the locking pin 111 is inserted into the locking hole 122, and the locking balls 112 pass through the locking ring 123 until the first half ring 11 and the second half ring 12 lock the patient's wrist tightly, preventing the first half ring 11 and the second half ring 12 from sliding on the wrist, thereby fixing the two ends of the pressure regulating belt assembly 20.

[0035] like Figure 1 As shown, one end of the compression band 21 extends from the back of the patient's palm, passes through the first fixing frame 13, and is snapped into place. The other end of the compression band 21 passes around the finger ring assembly 30, extends from the center of the patient's palm, passes through the first fixing frame 13, and is snapped into place.

[0036] Specifically, the compression band 21 includes a first fixing band 211, a second fixing band 212, and a connecting band 213. The connecting band 213 is elastic, and its two ends are fixedly connected to the first fixing band 211 and the second fixing band 212, respectively. A puncture hole is provided on the connecting band 213, and a connecting ring 214 is fitted inside the puncture hole. The bottom end of the compression member 22 passes through the puncture hole to apply pressure to the puncture point. The end of the first fixing band 211 away from the connecting band 213 is inserted through the first fixing frame 13 for connection, and the end of the second fixing band 212 away from the connecting band 213 is inserted through the second fixing frame 14 for connection. By inserting the end of the first fixing band 211 into the first fixing frame 13 and the end of the second connecting band 213 into the second fixing frame 14 for connection, the length of the compression band 21 passing through the first fixing frame 13 and the second fixing frame 14 can be adjusted, thereby aligning the bottom end of the compression member 22 with the puncture point for hemostasis.

[0037] Please refer to the following: Figure 3 and Figure 4 The first fixing band 211 has a beveled tooth at one end away from the connecting band 213. The side of the first fixing frame 13 away from the first half ring 11 has a through snap hole 132. A snap button 41 is provided on the snap hole 132. One side of the snap button 41 is hinged to one side of the snap hole 132. The bottom surface of the other side of the snap button 41 has an inclined snap beveled tooth 42. The inclination direction of the snap beveled tooth 42 is opposite to the direction of the beveled tooth on the first fixing band 211, so that it can be snapped. The snap beveled tooth 42 can be snapped onto the beveled tooth on the first fixing band 211 inserted into the first fixing frame 13. The first fixing frame 13 has a snap-on groove 131 on its side away from the first semi-ring 11, which communicates with the snap-on hole 132. The snap-on key 41 has a snap-on block 43 on its side away from the hinge edge, with protruding pads 44 on both sides of the snap-on block 43. The snap-on key 41 is fastened into the snap-on groove 131 via the snap-on block 43 and is then connected to the first fixing frame 13. A handle is located at the top of the snap-on block 43 for easy pulling it out of the snap-on groove 131. Fastening the snap-on block 43 into the snap-on groove 131 secures the snap-on key 41 to the first fixing frame 13, preventing the snap-on key 41 from detaching from the first fixing frame 13 and thus preventing the snap-on teeth 42 from failing to engage the end of the first fixing band 211.

[0038] When the end of the first fixing strap 211 is inserted into the first fixing frame 13, the snap block 43 is snapped into the snap groove 131. At the same time, the protruding pad 44 increases the friction of the snap block 43 in the snap groove 131, making it difficult for the snap block 43 to detach from the snap groove 131. The first fixing strap 211 passes through the first fixing frame 13, so that the snap teeth 42 and the teeth on the first fixing strap 211 engage with each other, so that the first fixing strap 211 can only be inserted at a time and cannot be withdrawn. When it is necessary to remove the first fixing strap 211 from the first fixing frame 13, the snap block 43 is pulled out from the snap groove 131, the snap button 41 is opened, so that the snap teeth 42 disengage from the teeth on the first fixing strap 211, and finally the first fixing strap 211 is withdrawn from the first fixing frame 13.

[0039] like Figure 5 and Figure 6 As shown, the second fixing band 212 has straight teeth at one end away from the connecting band 213, and the second fixing frame 14 has a T-shaped first slot 141 on the side away from the second half ring 12. The outer side of the side wall of the second fixing frame 14 has a through second slot 142. The second slot 142 is perpendicular to and connected to the first slot 141. A second insert 144 is inserted into the second slot 142. The end of the second insert 144 near the second half ring 12 is toothed and is inserted into the end of the second fixing band 212 away from the connecting band 213. A first insert 143 is inserted into the first slot 141 to cover the end of the second insert 144 away from and near the second half ring 12.

[0040] When the end of the second fixing band 212 is inserted into the second fixing frame 14, the first insert 143 is moved to expose the second insert 144. The second insert 144 is moved away from the second half ring 12 in the second slot 142, and the end of the second fixing band 212 is inserted into the second fixing frame 14. The second insert 144 is moved closer to the second half ring 12 so that the end of the second insert 144 is engaged with the straight teeth of the second fixing band 212, fixing the insertion length of the second fixing band 212. Then, by moving the first insert 143, the first insert 143 covers the second insert 144 to prevent the second insert 144 from sliding out of the second slot 142 and causing the second fixing band 212 to loosen.

[0041] like Figure 1As shown, the compression member 22 includes a compression post 221 and a compression hemisphere 222. The outer side of the compression post 221 has external threads, and the inner side of the connecting ring 214 has internal threads. The bottom end of the compression post 221 can be threaded into the connecting ring 214 and extends to the outer side of the connecting ring 214. The compression hemisphere 222 is located at the bottom end of the compression post 221, and the bottom surface of the compression hemisphere 222 is flat. The bottom end of the connecting ring 214 is provided with a snap-fit ​​cover 50. The bottom end of the snap-fit ​​cover 50 covers the area around the puncture point, positioning the puncture point and allowing the compression hemisphere 222 to accurately press on the puncture point, improving accuracy.

[0042] By adjusting the lengths of the first fixing strap 211 and the second fixing strap 212 inserted into the first fixing frame 13 and the second fixing frame 14 respectively, the connecting ring 214 is moved above the puncture point, so that the snap-fit ​​cover 50 covers the puncture point. The pressure column 221 is rotated so that the pressure hemisphere 222 slowly presses against the puncture point to apply pressure for hemostasis. At the same time, when a medical cotton ball is placed on the puncture point, the snap-fit ​​cover 50 can cover the medical cotton ball to prevent the medical cotton ball from sliding.

[0043] In this embodiment, the finger band assembly 30 includes an index finger ring 31, a thumb ring 32, and a finger band 33, with the index finger ring 31 and thumb ring 32 respectively positioned at both ends of the finger band 33. The finger band 33 is non-elastic, preventing its length from changing. By placing the index finger ring 31 and thumb ring 32 on the patient's index finger and thumb respectively, the finger band 33 covers the skin at the base of the thumb and forefinger of the palm. This allows the connecting band 213 to press against the finger band 33 when it wraps around the base of the thumb and forefinger. Simultaneously, the index finger ring 31 and thumb ring 32 can straighten and tighten the finger band 33, preventing changes in the length of the connecting band 213 from altering the position of the pressure post 221, thus ensuring continued support of the connecting band 213 by the finger band 33.

[0044] The working principle of this invention is as follows: In use, firstly, place the patient's wrist between the first half-ring 11 and the second half-ring 12, insert the locking pin 111 into the locking hole 122, and according to the thickness of the patient's wrist, lock the locking ring 123 between two adjacent locking balls 112, thus fixing the fixing ring 10 at the wrist; then, put the index finger ring 31 and thumb ring 32 on the patient's index finger and thumb respectively, so that the finger strap 33 covers the skin at the base of the thumb and forefinger; finally, insert the end of the first fixing strap 211 into the first fixing frame 1. 3. The end of the second fixing band 212 is wrapped around the finger strap 33 and inserted into the second fixing frame 14. At this time, the connecting band 213 presses on the finger strap 33. Finally, the snap-fit ​​cover 50 is placed on the puncture point. At the same time, the length of the first fixing band 211 inserted into the first fixing frame 13 is adjusted and the first fixing band 211 is tightened. The length of the second fixing band 212 inserted into the second fixing frame 14 is adjusted and the second fixing band 212 is tightened. The pressure column 221 is rotated so that the pressure hemisphere 222 is slowly pressed on the puncture point to apply pressure for hemostasis.

[0045] If the first connecting strap 213 needs to be removed, pull the snap block 43 out of the snap slot 131, open the snap button 41, so that the snap teeth 42 separate from the teeth of the first connecting strap 213, and then remove the first connecting strap 213 from the first fixing frame 13; if the second connecting strap 213 needs to be removed, move the first insert block 143 to expose the second insert block 144, move the second insert block 144 away from the second half ring 12 in the second slot 142, so that the end of the second insert block 144 separates from the straight teeth on the second fixing strap 212, and then remove the second connecting strap 213 from the second fixing frame 14.

[0046] The beneficial effects of this invention are as follows: This distal radial artery fixation and compression hemostasis device inserts the first fixing band 211 and the second fixing band 212 into the first fixing frame 13 and the second fixing frame 14 respectively, so that the compression column 221 moves above the puncture point. The fixing ring 10 is sleeved on the patient's wrist to fix both ends of the pressure adjustment band assembly and prevent the compression column 221 from sliding. The pressure on the puncture point is adjusted by the compression column 221 to achieve the ideal hemostasis effect. The finger ring band assembly 30 supports the connecting band 213 and protects the skin at the base of the thumb and forefinger. Moreover, the snap-fit ​​cover 50 can position the puncture point so that the compression hemisphere 222 can accurately press on the puncture point, improving accuracy.
