[0002] Radial artery puncture can be used for arterial angiography, cardiac radiofrequency ablation, arterial blood collection, arterial drug administration, and invasive arterial blood pressure monitoring. The radial artery puncture point is located at the palmar wrist joint. After radial artery puncture, in order to prevent massive bleeding symptoms at the puncture point, the puncture point needs to be pressurized for 6-8 hours, and the wrist joint needs to be braked for 6-8 hours, and the bleeding at the puncture point should be observed at any time.

[0003] At present, the conventional method of applying pressure bandage to the puncture point is: after covering the puncture point with sterile gauze or sterile cotton balls, an elastic bandage is used to wrap around the arm at the puncture point to achieve pressure bandage of the puncture point. This method has the following problems: when the elastic bandage is wrapped too tightly, it may cause the local blood return of the arm to be affected, and in severe cases, it may also cause local skin or tissue necrosis. When the elastic bandage is wrapped too loosely, it may not achieve the effect of compression and hemostasis, resulting in bleeding at the puncture point, congestion at the puncture point or other complications, which brings difficulties to the care of medical staff; the conventional method of braking the wrist joint is: fixing the operated limb to the bed rail with a restraint belt.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. The content of the utility model is further described below in conjunction with the drawings:

[0024] Example 1

[0025] Refer to the instruction manual Figure 1A compression hemostasis braking device after radial artery puncture includes a fixing plate 1, a fixing member 2, a clamping member 3 and a pressing member 4.

[0026] See attached Figure 1 The fixing plate 1 is a straight plate, and its top surface in contact with the operated limb is an arc-shaped surface. A flexible buffer pad can be laid on the arc-shaped surface of the top surface of the fixing plate 1. The flexible buffer pad can be a sponge pad layer, a silicone pad layer or a rubber pad layer, etc., which can increase the comfort of the operated limb being fixed on the fixing plate 1, and at the same time avoid collision and friction when the wrist joint contacts the fixing plate 1. Moreover, the flexible buffer pad can improve the tightness of the fixing plate 1 and the operated limb, so that the operated limb is not easy to be dislocated and moved on the fixing plate 1, so that the compression and hemostasis pressure provided by the clamping member 3 and the pressing member 4 to the puncture point is stable and reliable, and the compression and hemostasis position is accurate;

[0027] The fixing member 2 includes a fixing belt whose two ends are connected to the two sides of the fixing plate 1, and the length of the fixing belt is adjustable (specifically, the fixing belt is composed of two connecting belts, one end of the two connecting belts is respectively connected to the two sides of the fixing plate 1, and the other end is provided with Velcro that can be adhered to each other, so as to realize the mutual connection and adjustable length of the connecting belts. After the surgical limb is placed on the fixing plate 1, the two connecting belts are used to wrap the surgical limb therein and fix it by Velcro), or, a fixing belt surrounding the fixing plate 1, and the length of the fixing belt is adjustable (specifically, the fixing belt is composed of one connecting belt, and the two ends of the connecting belt are provided with Velcro that can be adhered to each other, so as to realize the mutual connection and adjustable length of the connecting belt. After the surgical limb is placed on the fixing plate 1, the connecting belt is used to wrap around the fixing plate 1 and the outside of the surgical limb and then fixed by Velcro). Fixing belts are provided at both ends of the fixing plate 1, and the space surrounded by the fixing belt and the fixing plate 1 forms a fixed space for fixing the surgical limb;

[0028] After the operated limb is placed on the fixing plate 1, one end of the fixing plate 1 extends to the palm of the operated limb, and the other end extends to the forearm or upper arm of the operated limb, so that the wrist joint is located between the two fixing belts on the fixing plate 1, and the operated limb enters the fixed space surrounded by the fixing belt and the fixing plate 1. The fixing belt is used to fix the palm, forearm or upper arm on the fixing plate 1 to achieve braking of the wrist joint. At the same time, after the wrist joint is braked, the movement of the operated limb is not restricted. The operated limb can move within the small allowed range with the fixing plate 1, and no secondary injury to the operated limb will be caused.

[0029] See attached Figure 1 A pressurizing component for applying pressure to the puncture point is arranged on the fixing plate 1 between the two fixing belts. The pressurizing component includes a clamping member 3 for clamping on the outside of the patient's operated limb and a pressing member 4 for pressing on the puncture point. The pressing member 4 is installed on the clamping member 3.

[0030] See attached Figure 2 , 3The clamping member 3 includes a hinge shaft 34, a clamping body 32 and a torsion spring 33. The hinge shaft 34 is arranged on the top surface of the fixed plate 1. The clamping body 32 includes a clamping portion 321, a connecting portion 322 and an operating portion 323 which are connected in sequence. The bottom of the connecting portion 322 is hinged on the hinge shaft 34. The clamping portion 321 is above the fixed plate 1. The torsion spring 33 is sleeved on the hinge shaft 34. The clamping portion 321 is an arc-shaped structure with an opening facing downward, and an accommodating space for the surgical limb is formed between the clamping portion 321 and the fixed plate 1.

[0031] Specifically, a connecting seat is provided on the top surface of the fixed plate 1 and the bottom of the connecting part 322, and a through hole is opened on the connecting seat for the hinge shaft 34 to pass through, so that the clamp body 32 as a whole can rotate around the hinge shaft 34, and the torsion spring 33 includes a spring coil wound with multiple turns and a torsion arm connected to the two ends of the spring coil, and the spring coil is sleeved on the hinge shaft 34, one torsion arm is in conflict with the bottom of the operating part 323, and the other torsion arm is in conflict with the top surface of the fixed plate 1. The above connection structure and principle are similar to the claw-type hairpins in daily life.

[0032] The clamping portion 321 and the operating portion 323 are located at both ends of the connecting portion 322. When the operating portion 323 is pressed downward, the resilience of the spring coil of the torsion spring 33 needs to be overcome to rotate the connecting portion 322 around the hinge shaft 34, so that the clamping portion 321 is lifted up to increase the accommodating space. When the operating portion 323 is released, the clamping portion 321 is pressed back to its original position due to the resilience of the spring coil of the torsion spring 33, thereby applying pressure to the puncture point.

[0033] Since the area of ​​the clamping part 321 is large, when the clamping part 321 contacts the skin near the puncture point, the contact area is large, and the pressure of the clamping part 321 cannot be concentrated on the puncture point, resulting in poor compression and hemostasis effect. Therefore, a pressing member 4 that can press on the puncture point is installed on the clamping part 321;

[0034] In one embodiment, the pressing piece 4 includes a pressing block 44 and an elastomer 45. The pressing block 44 is connected and installed on the clamping portion 321 and is at the bottom of the clamping portion 321. The elastomer 45 is installed at the bottom of the pressing block 44 and the elastomer 45 faces the fixing plate 1. The elastomer 45 is made of silicone, rubber or an air bag. The elastomer 45 is in flexible contact with the patient's operated limb to make the pressure distribution more uniform and improve comfort. At the same time, the elastomer 45 and the clamping body 32 are in local contact with the skin to apply pressure, which will not affect the blood circulation of the operated limb.

[0035] The method of using the postoperative compression hemostasis brake device for radial artery puncture in this embodiment is as follows: after radial artery puncture, cover the puncture point with sterile gauze or sterile cotton balls, press the operating part 323 to lift and open the clamping part 321, place the surgical limb on the fixing plate 1, move the surgical limb so that the elastic body 45 is aligned with the puncture point, slowly release the operating part 323 to make the elastic body 45 apply pressure to the puncture point, and then connect and fix the two fixing belts to the palm and the forearm or upper arm respectively.

[0036] Example 2

[0037] In the above-mentioned embodiment 1, the inventors found that the pressing force of the pressing member 4 is completely generated by the torsion spring 33, and the pressing force is constant, and the pressing force cannot be adjusted according to the different recovery periods and individual differences of the patients, which reduces the practicality of the device. Therefore:

[0038] In another embodiment, the pressing member 4 includes a threaded rod 42, a knob 43, a pressing block 44 and an elastomer 45. A screw hole for the threaded rod 42 to be screwed is opened on the clamping portion 321. The knob 43 and the pressing block 44 are respectively fixedly installed on the top and bottom ends of the threaded rod 42. The elastomer 45 is installed at the bottom end of the pressing block 44 so that the elastomer 45 faces the fixed plate 1. The elastomer 45 is made of silicone or rubber or the elastomer 45 is an airbag. The elastomer 45 is in flexible contact with the patient's operated limb to make the pressure distribution more uniform and improve comfort. At the same time, the elastomer 45 and the clamping body 32 are in local contact with the skin to apply pressure, which will not affect the blood circulation of the operated limb.

[0039] When the pressing force needs to be adjusted, the pressing block 44 and the elastic body 45 can be rotated in or out toward the surgical limb relative to the clamping portion 321 by rotating the knob 43 in a forward or reverse direction.

[0040] It should be noted that the structures and functions of the fixing plate 1, fixing member 2, and clamping member 3 used in Example 2 and Example 1 are consistent, and the only difference lies in the structure of the pressing member 4 and the connection structure or connection relationship between the pressing member 4 and the clamping member 3.

[0041] The method of using the postoperative compression hemostasis brake device for radial artery puncture in this embodiment is as follows: after radial artery puncture, cover the puncture point with sterile gauze or sterile cotton balls, press the operating part 323 to lift and open the clamping part 321, place the surgical limb on the fixing plate 1, move the surgical limb so that the elastic body 45 is aligned with the puncture point, slowly release the operating part 323 to make the elastic body 45 apply pressure to the puncture point, and then connect and fix the two fixing belts to the palm part and the forearm or upper arm part respectively. When the pressing force needs to be adjusted, the pressing block 44 and the elastic body 45 can be rotated in or out in the direction of the surgical limb relative to the clamping part 321 by rotating the knob 43 in the forward or reverse direction to achieve adjustable pressing force.

[0042] Example 3

[0043] The inventors also found that although the technical solution in Example 2 can adjust the pressing force, since the positions of the puncture points of different patients may be different, the technical solutions in Examples 1 and 2 can only adjust the position by moving the patient's surgical limb or the entire device so that the pressing member 4 can accurately press on the puncture point. In this way, the position of the pressing member 4 cannot be conveniently adjusted, which reduces the practicality of the device. Therefore:

[0044] In another embodiment, referring to the attached Figure 1 , 4 , 5. The pressing member 4 includes a sliding seat 41, a threaded rod 42, a knob 43, a pressing block 44 and an elastic body 45. An adjusting groove 324 is provided along the length direction of the clamping portion 321. The sliding seat 41 is sleeved on the adjusting groove 324 through a groove 411 provided thereon, and can slide along the adjusting groove 324. A screw hole for the threaded rod 42 to be screwed is provided at the center of the sliding seat 41. The knob 43 and the pressing block 44 are respectively fixedly mounted on the top and bottom ends of the threaded rod 42. The elastic body 45 is mounted on the bottom end of the pressing block 44 so that the elastic body 45 faces the fixed plate 1; the elastic body 45 is made of silicone or rubber material or the elastic body 45 is an air bag. The elastic body 45 is in flexible contact with the patient's operated limb, which makes the pressure distribution more uniform and improves the comfort. At the same time, the elastic body 45 and the clamping body 32 are in local contact with the skin to apply pressure, which will not affect the blood circulation of the operated limb.

[0045] See attached Figure 1 Two slide grooves 11 are provided on both sides of the fixed plate 1 along its length direction. The fixing belt is connected and installed on the top surface of the fixed plate 1 through a first slider 21 matched and sleeved in the slide groove 11. The clamping member 3 is connected and installed on the top surface of the fixed plate 1 through a second slider 31 matched and sleeved in the slide groove 11. The first slider 21 and the second slider 31 can only slide along the length direction of the slide groove 11.

[0046] Through the above design, the pressing member 4 can be moved in four directions: front, back, left and right, and the position of the pressing member 4 can be adjusted conveniently and quickly so that the pressing member 4 can be accurately pressed on the puncture point.

[0047] The shapes of the slide groove 11, the first slider 21 and the second slider 31 are T-shaped, truncated cone-shaped or other equivalent forms. At the same time, the slide groove 11 extends out of the end surface of the fixed plate 1 respectively, and its function is to enable the first slider 21 and the second slider 31 to be taken out from the slide groove 11, so as to facilitate the clamping member 3 to be matched and sleeved in the slide grooves 11 on different sides through the second slider 31, so that the clamping member 3 can be suitable for the left and right hands of the patient.

[0048] It should be noted that the structures and functions of the fixing plate 1, fixing member 2, and clamping member 3 used in Example 3 are consistent with those of Examples 1 and 2, and the only difference lies in the structure of the pressing member 4 and the connection structure or connection relationship between the pressing member 4 and the clamping member 3.

[0049] At the same time, the fixing belt is fixedly connected to the top surface of the first slider 21; a connecting seat is provided on the top surface of the second slider 31 and the bottom of the connecting part 322, and a through hole is opened on the connecting seat for connecting and installing the hinge shaft 34, so that the clamp body 32 as a whole can rotate around the hinge shaft 34, and the torsion spring 33 includes a spring coil wound with multiple turns and a torsion arm connected to the two ends of the spring coil, and the spring coil is sleeved on the hinge shaft 34, one torsion arm is in contact with the bottom of the operating part 323, and the other torsion arm is in contact with the top surface of the second slider 31.

[0050] The method of using the postoperative compression hemostasis brake device for radial artery puncture in this embodiment is as follows: after the radial artery puncture, cover the puncture point with sterile gauze or sterile cotton balls, press the operating part 323 to lift and open the clamping part 321, place the operated limb on the fixing plate 1, and then respectively connect and fix the two fixing belts to the palm part and the forearm or upper arm part, slide along the length direction of the slide groove 11 through the second slider 31, and synchronously slide the slide seat 41 along the adjustment groove 324 until the pressing block 44 and the elastic body 45 are aligned with the puncture point, so that the elastic body 45 applies pressure to the puncture point. When the pressing force needs to be adjusted, the pressing block 44 and the elastic body 45 can be rotated in or out in the direction of the operated limb relative to the slide seat 41 by rotating the knob 43 in the forward or reverse direction, so as to achieve adjustable pressing force.

[0051] Obviously, the above-mentioned radial artery puncture postoperative compression hemostasis braking device and the corresponding method can be modified and / or added with components without departing from the field and scope of the present invention.

[0052] It is also clear that although the present utility model has described the radial artery puncture postoperative compression hemostatic brake device in detail, technicians in this field will certainly be able to obtain many other equivalent forms of radial artery puncture postoperative compression hemostatic brake devices and corresponding methods. The radial artery puncture postoperative compression hemostatic brake device and the corresponding method have the characteristics as described in the claims, and therefore are all within the scope of the protection field defined thereby.
