Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary devices, and particularly to an adjustable radial artery compression device after coronary angiography. Background Art

[0002] At present, coronary angiography is the main means for diagnosing coronary heart disease. Compared with the transfemoral artery approach, the transradial artery approach has more prominent advantages, which can reduce the incidence of complications and shorten the hospital stay. Although coronary angiography has many advantages, complications such as bleeding, hematoma formation, and pain are likely to occur after the operation. Among them, ice compress is a simple, effective, and economical method to relieve limb swelling and pain after the operation. At present, the common ice compress method is to bind the ice pack near the radial artery through a strap or an inflatable cuff, and perform ice compress while applying pressure to the radial artery.

[0003] Although the above method has simple requirements for the equipment, since the ice pack will melt, resulting in a decline in its ice compress effect, it is necessary to untie the strap and then replace the ice pack. This easily leads to the loss of good compression on the radial artery during the process of replacing the ice pack, and after replacing the ice pack, it is necessary to re-bind and wrap the ice pack again. The operation process is troublesome and time-consuming, and it is easy to cause discomfort to the patient. In addition, when using this method for pressure ice compress, it is not convenient to adjust the pressure on the arm according to the patient's tolerance. For this reason, this solution proposes an adjustable radial artery compression device after coronary angiography. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The adjustment mechanism is convenient for adjusting the length of the telescopic column and the distance between the bottom plate and the top plate to become smaller, so that the volume of the entire device can be reduced when not in use, which is convenient for storage and placement. The telescopic rod can also be driven to move accordingly while the length of the telescopic column is changed, so that when it is used for patients with different wrist thicknesses, the telescopic plate can be used to support one side of the patient's wrist to prevent it from loosening during use, thereby achieving the purpose of easy adaptive adjustment according to the different thicknesses of the patient's wrist.

[0023] 2. By adjusting the length of the telescopic column, the distance between the top plate and the bottom plate and the position of the telescopic plate can be quickly adjusted, so that the pressing plate can be quickly pressed on the radial artery on the patient's wrist for wrists of different thicknesses, and then the distance between the top plate and the upper telescopic rod can be adjusted by adjusting the connecting piece, so as to further fine-tune the distance between the top plate and the bottom plate, so that the pressing plate can be pressed tightly against the radial artery, and then the pressure applied by the pressing plate can be clearly known according to the value displayed on the pressure display, thereby achieving the purpose of convenient pressure adjustment.

[0024] 3. The setting of the cold compress mechanism can not only facilitate pressing the cold compress bag just above the pressing plate to cool down the patient's radial artery, but also the partition divides the placement frame into two cold compress bag placement spaces. The placement frame can be lifted and then turned over, thereby achieving the purpose of convenient and quick replacement of the cold compress bag.

[0025] 4. Through the setting of the linkage component, the adjustment column can be driven to move forward when the placement frame is lifted, and the top plate will approach the bottom plate, so that the pressing plate can further press the radial artery, thereby compensating for the pressure reduction of the pressing plate on the radial artery caused by the cold compress belt losing its pressure on the pressing plate due to the lifting of the placement frame. When the placement frame rotates downward, the linkage component can be used to drive the top plate to move up, so that the pressure applied by the pressing plate on the radial artery can be restored.

[0039] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.

[0040] Embodiment 1:

[0041] Please combine Figures 1-11 , a kind of adjustable radial artery pressurizing device after coronary angiography in this embodiment, includes:

[0042] The installation assembly includes a bottom plate 1, a top plate 2 arranged on the top surface of the bottom plate 1, and a telescopic column installed between the top plate 2 and the bottom plate 1. A pillow pad 3 is installed on the top surface of the bottom plate 1 through an elastic member, a pressing plate is installed on the bottom surface of the top plate 2, a buffer cavity is opened inside the bottom plate 1, and a slide groove connected to the buffer cavity is opened on the top surface of the bottom plate 1. The elastic member includes a sleeve rod 36 fixed in the buffer cavity along the length direction of the bottom plate 1, two movable sleeves 35 movably sleeved on the outer periphery of the sleeve rod 36, and two connecting rods 34 hinged on the bottom surface of the pillow pad 3. The other ends of the two connecting rods 34 pass through the slide groove and are respectively hinged to the top surfaces of the two movable sleeves 35. The two connecting rods 34 are in an "eight" shape. The width of the slide groove is smaller than the pillow. The width of the pad 3 and the length of the slide groove are also smaller than the length of the pillow pad 3. A spring 1 is connected between the two movable sleeves 35. When in use, the patient's wrist is placed on the pillow pad 3, and the wrist is located between the top plate 2 and the bottom plate 1. The pillow pad 3 will drop after being subjected to pressure, driving the two movable sleeves 35 away from each other, and the spring 1 will be stretched accordingly, thereby playing a buffering role until the pillow pad 3 abuts against the bottom plate 1, and then the length of the telescopic column is adjusted until the pressing piece is pressed tightly against the patient's wrist, and then the length of the telescopic column is locked to pressurize the radial artery. After the patient's wrist is lifted from the pillow pad 3, the spring 1 contracts, driving the pillow pad 3 to automatically move up and return to its original position.

[0043] The pressing sheet includes two fixing sheets 26 and a strap 27 fixed between the two fixing sheets 26, the top surfaces of the two fixing sheets 26 are fixed with connecting columns 33, and baffles 25 are fixed on both sides of the top surface of the strap 27. The bottom surface of the top plate 2 is provided with two connecting holes, and pressure sensors 46 are installed in the two connecting holes. The tops of the two connecting columns 33 extend into the connecting holes and are connected to the pressure sensors 46. The top surface of the top plate 2 is provided with a pressure display 16 connected to the two pressure sensors 46. A plurality of small holes are provided on the strap 27, and the arrangement of the small holes facilitates ventilation and the transfer of temperature in the cold compress bag. After the top plate 2 is lowered, the pressing sheet is lowered accordingly until the strap 27 in the pressing sheet is pressed tightly against the radial artery of the patient, and the pressure applied to the pressing sheet is measured by the pressure sensor 46 and finally displayed on the pressure display 16, thereby helping medical staff to have a clearer judgment on the pressure applied to the radial artery of the patient.

[0044] The telescopic column includes a mounting sleeve 11, a lower telescopic rod 10 movably sleeved inside the mounting sleeve 11, and an upper telescopic rod 14. The bottom of the lower telescopic rod 10 is fixedly connected to the bottom plate 1. A connecting member for adjusting the distance between the two is installed between the top of the upper telescopic rod 14 and the top plate 2. The connecting member includes an adjusting column 41 rotatably connected to the top plate 2 and a limiting rod 43 fixed to the bottom surface of the top plate 2. The adjusting column 41 includes a smooth rod rotatably connected to the top plate 2 and a threaded column fixed to the bottom of the smooth rod. The top of the smooth rod extends above the top plate 2 and is provided with a knob 15. A second threaded hole and a limiting hole 50 are formed in the top of the upper telescopic rod 14. The other end of the threaded column extends into the second threaded hole and is screwed thereto. The bottom of the limiting rod 43 extends into the limiting hole 50. A locking bolt 55 is screwed on the outer periphery of the upper telescopic rod 14, and one end of the locking bolt 55 extends into the limiting hole 50 and abuts against the limiting rod 43. By adjusting the length of the telescopic column, the pressing piece can be quickly pressed against the patient's wrist. After locking the length of the telescopic column, the distance between the top plate 2 and the bottom plate 1 can be further adjusted so that the pressing piece can gradually apply pressure to the radial artery. During adjustment, turn the knob 15 in the clockwise direction, and the adjusting column 41 rotates in the clockwise direction accordingly. Under the restriction of the limiting rod 43, the threaded column moves towards the inside of the second threaded hole, and the top plate 2 descends accordingly, so that the pressing piece further applies pressure to the radial artery. The pressure value displayed by the pressure display 16 can help medical staff adjust the pressure applied to the radial artery. When the pressure is too high, turn the knob 15 in the counterclockwise direction, the top plate 2 moves upward, and the pressure of the pressing piece on the radial artery decreases. Turning the knob 15 clockwise applies pressure to the radial artery.

[0045] The pressing mechanism includes a telescopic plate slidably connected between the bottom plate 1 and the top plate 2. The pressing mechanism includes a fixed sleeve 8 and two movable plates 7 with one end movably sleeved in the fixed sleeve 8. T-shaped limit blocks 52 are fixed to the mutually remote ends of the two movable plates 7. Limit grooves 6 matching the limit blocks 52 are formed in the top surface of the bottom plate 1 and the bottom surface of the top plate 2. The two limit blocks 52 are respectively slidably connected in the two limit grooves 6. Since the wrist thicknesses of different patients are different, when pressing on the radial artery, it is necessary to keep the whole device stable. Therefore, when the patient's wrist is relatively thin, the length of the telescopic column is shortened, the distance between the top plate 2 and the bottom plate 1 becomes smaller, and at the same time, the telescopic plate is moved to the side away from the telescopic column, so as to use the telescopic plate to abut against the side of the patient's wrist close to the telescopic column, avoiding the device moving towards the side close to the telescopic column when the pressing piece presses on the patient's wrist. On the contrary, when the patient's wrist is thick, the telescopic column is extended, the distance between the top plate 2 and the bottom plate 1 is adjusted to become larger, and at the same time, the telescopic plate is also moved to the side close to the telescopic column, so that the telescopic plate will not hinder the fixation of the patient's wrist. Finally, the telescopic plate also abuts against one side of the patient's wrist. After the pressing piece presses on the patient's wrist, the length of the telescopic column can be locked. The setting of the limit blocks 52 and the limit grooves 6 enables the telescopic plate to move between the top plate 2 and the bottom plate 1 and at the same time change its own length as the distance between the top plate 2 and the bottom plate 1 changes. When the distance between the top plate 2 and the bottom plate 1 becomes larger, the two movable plates 7 are pulled outwards, and the length of the telescopic plate becomes larger. On the contrary, when the distance between the top plate 2 and the bottom plate 1 becomes smaller, the two movable plates 7 contract into the fixed sleeve 8 accordingly.

[0046] Adjusting mechanism, which is installed on the mounting sleeve 11 and is used to adjust the position of the telescopic plate when adjusting the length of the telescopic column. The adjusting mechanism includes a bidirectional screw 51 rotatably connected inside the mounting sleeve 11, an adjusting gear 54 sleeved on the outer periphery of the bidirectional screw 51, and an adjusting frame 13 provided inside the mounting sleeve 11. Threaded holes 1 are opened at the ends of the lower telescopic rod 10 and the upper telescopic rod 14 close to each other. The two ends of the bidirectional screw 51 are respectively screwed into the threaded holes 1 on the lower telescopic rod 10 and the upper telescopic rod 14. A tooth groove meshing with the adjusting gear 54 is opened on the inner wall of the long side of one side of the adjusting frame 13, and one end of the adjusting frame 13 extends to the outside of the mounting sleeve 11 and is fixed with an adjusting plate 12. The other end of the adjusting frame 13 extends to the outside of the other side of the mounting sleeve 11 and is fixedly connected with the fixed sleeve 8. The outer periphery of the mounting sleeve 11 is threadedly connected with a positioning bolt 9, and one end of the positioning bolt 9 abuts against the outer periphery of the adjusting frame 13. When it is necessary to adjust the distance between the top plate 2 and the bottom plate 1, first loosen the positioning bolt 9, and then when the adjusting plate 12 is moved towards the side close to the telescopic plate, the adjusting frame 13 will drive the adjusting gear 54 to rotate forward, thereby driving the bidirectional screw 51 to rotate forward. The upper telescopic rod 14 and the lower telescopic rod 10 will approach each other under the drive of the forward rotation of the bidirectional screw 51, the length of the telescopic column becomes smaller, the distance between the top plate 2 and the bottom plate 1 becomes smaller, and the telescopic plate also moves towards the side away from the telescopic column under the drive of the adjusting frame 13, so as to be suitable for patients with thinner wrists. After the patient places the wrist on the pillow pad 3, shorten the telescopic column until the pressing piece can quickly press on the patient's wrist, and then tighten the positioning bolt 9. Rely on the friction between the positioning bolt 9 and the adjusting frame 13 to lock the adjusting frame 13, thereby keeping the length of the telescopic column unchanged. Then, further adjust the pressure applied by the pressing piece on the patient's wrist through the adjusting connecting piece. On the contrary, when it is necessary to adjust the distance between the top plate 2 and the bottom plate 1 to become larger, loosen the positioning bolt 9 and then drive the adjusting frame 13 to move towards the side away from the telescopic plate, thereby driving the bidirectional screw 51 to rotate reversely. The distance between the upper telescopic rod 14 and the lower telescopic rod 10 becomes larger, the bottom plate 1 and the top plate 2 move away accordingly, and the telescopic plate also moves towards the side close to the telescopic column, so as to be suitable for patients with thicker wrists. When the device is not in use, the telescopic column can also be adjusted to become shorter, thereby reducing the external volume of the entire device and making it convenient for storage.

[0047] Cold compress mechanism, which includes a placement frame 20 rotatably connected to the top surface of a top plate 2 and a partition plate 53 fixed inside the placement frame 20. Elastic bands 19 are fixed to both the top and bottom of the placement frame 20. The partition plate 53 divides the inside of the placement frame 20 into two placement spaces. Cold compress bags can be placed in both placement spaces. After the cold compress bag is placed in the placement space, it is tied tightly with the elastic band 19. A storage groove 28 for storing the placement frame 20 is provided on the top surface of the top plate 2. The storage groove 28 is located directly above the pressing piece. A fixing groove 18 is provided on one side of the storage groove 28. A mounting shaft 48 is rotatably connected inside the fixing groove 18. One short side of the placement frame 20 is rotatably connected to a connecting plate 30 fixedly connected to the outer circumference of the mounting shaft 48. During cold compress, first place the cold compress bag in one of the placement spaces in the upper part of the placement frame 20 and tie it tightly with the elastic band 19. Then lift one end of the placement frame 20 upward until the entire placement frame 20 is outside the storage groove 28. After that, rotate the placement frame 20 by 180 degrees so that the upward-facing cold compress bag is vertically downward. Then press down the placement frame 20 until it is completely stored inside the storage groove 28. At this time, the cold compress bag will press on the top of the strap 27 on the pressing piece. When the pressing piece presses on the patient's wrist, the cold compress bag can cool the patient's radial artery.

[0048] Locking mechanism, which is installed on the placement frame 20 and used to lock it in the storage groove 28. A card slot 21 is provided at the top of the side of the placement frame 20 away from the fixing groove 18. Two fixing holes 32 are provided at one end of the top plate 2, respectively located on both sides of the card slot 21. The locking mechanism includes a fixing shaft 22 fixed to the other short side of the placement frame 20, a positioning plate 29 movably sleeved on the outer circumference of the fixing shaft 22. A stop block 23 is fixed to one end of the fixing shaft 22. A plurality of handles 24 are fixed to the outer circumference of the stop block 23. A second spring is connected between the positioning plate 29 and the stop block 23. Two fixing columns 31 that match the fixing holes 32 are fixed to the side of the positioning plate 29 away from the stop block 23. When the placement frame 20 is stored inside the storage groove 28, the positioning plate 29 abuts against the end of the top plate 2 under the action of the second spring. The two fixing columns 31 are respectively engaged in the two fixing holes 32, so that the placement frame 20 will not loosen, and thus the cold compress bag can be tightly attached to the top of the pressing piece. When it is necessary to replace the cold compress bag, first place the new cold compress bag in the upper placement space of the placement frame 20 and fix the cold compress bag with the elastic band 19. Then move the positioning plate 29 away from the top plate 2 until the fixing columns 31 completely withdraw outside the fixing holes 32. Then the placement frame 20 can be lifted upward until the entire placement frame 20 is outside the storage groove 28. Then rotate the placement frame 20 by 180 degrees to swap the positions of the new cold compress bag and the old cold compress bag. Then press down the placement frame 20 until it completely enters the storage groove 28. Then release the positioning plate 29 so that the two fixing columns 31 are respectively inserted into the two fixing holes 32, thereby locking the placement frame 20, and finally achieving the purpose of conveniently and quickly replacing the cold compress bag.

[0049] Embodiment 2:

[0050] Combination Figure 1 - Figure 3 , Figure 5 , Figure 6 , Figure 9 and Figure 10 The present embodiment is further improved on the basis of the embodiment 1 in that: a mounting groove 4 is provided at one end of the bottom plate 1 away from the telescopic column, a limiting mechanism is installed in the mounting groove 4, the limiting mechanism comprises a connecting shaft 39 rotatably connected in the mounting groove 4, a side plate 5 fixed on the outer periphery of the connecting shaft 39 and two driving racks 38 slidably connected in the mounting groove 4, two driving gears 40 are sleeved on the outer periphery of the connecting shaft 39, a fixed plate 37 is fixed on one of the movable sleeves 35 close to the mounting groove 4, the two driving gears 40 are respectively meshed with the two driving racks 38, one end of the two driving racks 38 extends into the buffer cavity and is fixedly connected to the fixed plate 37, after the pillow pad 3 is moved downward by the weight of the wrist, the two movable sleeves 35 in the elastic member move away from each other, thereby driving the fixed plate 37 to move to the bottom of the pillow pad 3. The side plate 5 is rotated 90 degrees to block the wrist on the side away from the telescopic column, thereby effectively preventing the entire device from falling off the wrist. After the wrist is lifted from the pillow pad 3, the two movable sleeves 35 approach each other, thereby driving the fixed plate 37 and the driving rack 38 to move into the buffer cavity. The driving rack 38 drives the driving gear 40 to reverse at this time, and the fixed plate 37 is flipped downward until the pillow pad 3 returns to its original position. The side plate 5 also reverses 90 degrees and returns to its original position, thereby preventing the patient from pulling his wrist out from between the top plate 2 and the bottom plate 1.

The linkage mechanism includes two linkage racks 17 arranged in the installation cavity 47, a transmission rack 45 fixed on the side wall of one of the linkage racks 17, and a transmission gear 42 sleeved on the outer periphery of the smooth rod. One end of each of the two linkage racks 17 is connected to the inner wall of one side of the installation cavity 47 through a reset member. The other ends of the two linkage racks 17 both extend to the inside of the fixing groove 18 and are respectively engaged with the two linkage gears 49. After the transmission rack 45 is engaged with the transmission gear 42, it will drive the transmission gear 42 to rotate when the linkage rack 17 moves. The reset member includes a guiding column 44 fixed on the inner wall of the installation cavity 47 away from the fixing groove 18 and a reset spring movably sleeved on the outer periphery of the guiding column 44. A buffer hole for inserting the guiding column 44 is formed at one end of the linkage rack 17. One end of the reset spring is fixedly connected to the inner wall of the installation cavity 47, and the other end of the reset spring is fixedly connected to the linkage rack 17. When the placement frame 20 is lifted from the storage groove 28 when replacing the cold compress bag, the pressure exerted by the pressing piece on the patient's radial artery decreases due to the loss of the pressure of the cold compress bag. At this time, when the placement frame 20 is lifted upward, it will drive the installation shaft 48 to rotate forward, and then drive the linkage gear 49 to rotate forward. After the linkage gear 49 rotates forward, it will drive the linkage rack 17 to move towards the inside of the installation cavity 47. The transmission rack 45 will be engaged with the transmission gear 42 during the movement. After the engagement, it will drive the transmission gear 42 to rotate clockwise during the continuous movement, thereby driving the adjusting column 41 to rotate clockwise, and the top plate 2 will move towards the side close to the bottom plate 1, and the pressure of the pressing piece on the patient's radial artery will increase accordingly, so as to compensate for the reduced pressure part due to the upward movement of the placement frame 20 and ensure the stability of the pressure at the patient's radial artery. On the contrary, when the placement frame 20 rotates downward again and returns to the inside of the storage groove 28, it will drive the installation shaft 48 to rotate reversely, and the transmission rack 45 will also move towards the fixing groove 18 following the linkage rack 17, thereby driving the transmission gear 42 to rotate counterclockwise, and the top plate 2 will move away from the bottom plate, thereby reducing the pressure exerted by the pressing piece on the patient's radial artery and avoiding excessive pressure at the patient's radial artery after the cold compress bag is pressed on the pressing piece again.
