Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a compression hemostasis device after radial artery puncture. Background Art
[0002] Radial artery puncture is a medical procedure commonly used to obtain a blood sample, monitor blood pressure, or perform interventional procedures. The radial artery, a major artery in the arm, is typically accessed on the inside of the wrist. This procedure requires specialized medical personnel and strict aseptic techniques. During radial artery puncture, the medical professional typically cleans the puncture site with disinfectant and then uses a catheter with a needle to puncture the artery for subsequent treatment or testing.
[0003] After radial artery puncture, compression hemostasis is required. The existing method for this is to use a compression hemostat, which wraps the entire wrist and then pumps air into it to apply pressure. However, this method requires wrapping the entire wrist tightly, which can affect blood circulation for extended periods of time, leading to localized swelling and pain in the wrist and causing significant discomfort. Utility Model Content
[0004] The purpose of the utility model is to provide a compression hemostasis device after radial artery puncture that avoids excessive tightening, and effectively solves the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.
[0006] A compression hemostasis device for post-radial artery puncture includes a C-shaped arm, one end of the C-shaped arm is provided with a mounting column, the mounting column passes through the C-shaped arm, the end of the mounting column is provided with a pressure plate, and the mounting column is provided with an adjustment mechanism. The adjustment mechanism is used to drive the pressure plate to adjust along the length direction of the mounting column to provide compression force.
[0007] It can be seen that the clamping effect provided by the pressure plate and the end of the C-arm away from the mounting column can provide pressure on the puncture site of the patient's wrist, thereby achieving a hemostatic effect. Compared with the traditional hemostatic method of tightening with a strap, this compression hemostasis device is a two-point clamping method, which will not cause excessive tightening of the entire wrist, and will not affect the blood circulation in the wrist, avoid local swelling and pain, and improve the patient's comfort.
[0008] Furthermore, a threaded hole extending downward is provided at the top of the mounting post, and a sliding cavity extending upward and passing through the threaded hole is provided at the bottom end of the mounting post. The adjustment mechanism includes a threaded rod and a telescopic rod. The telescopic rod is vertically slidably installed in the sliding cavity, and the bottom end extends to the bottom of the mounting post. The pressure plate is fixed on the bottom end of the telescopic rod, and the threaded rod is screwed into the threaded hole with matching threads. The bottom end of the threaded rod extends into the sliding cavity and is rotatably connected to the top of the telescopic rod. The top of the telescopic rod extends to the top of the mounting post and is provided with a pinch handle.
[0009] By pinching the handle and applying force to twist the threaded rod, the threaded rod rotates and cooperates with the thread of the threaded hole, which can drive the telescopic rod to slide downward, and then push the pressure plate downward to achieve a compression effect. By pinching the handle and twisting the threaded rod in the opposite direction, the telescopic rod and the pressure plate can be driven upward, thereby canceling the compression force and facilitating the removal of the device from the patient's wrist.
[0010] Furthermore, the cross section of the sliding cavity is rectangular, and the cross section of the telescopic rod is rectangular to match the sliding cavity.
[0011] The cross-sections of the sliding cavity and the telescopic rod are respectively in the form of mutually matching rectangles, which play a guiding and limiting role, preventing the telescopic rod from rotating in the sliding cavity. Combined with the rotating connection between the threaded rod and the telescopic rod, the threaded rod can be prevented from driving the telescopic rod to rotate synchronously when rotating, thereby preventing the pressure plate from rotating when contacting the hemostatic cotton, causing the hemostatic cotton and the puncture point to be misaligned, thereby affecting the compression and hemostasis effect.
[0012] Furthermore, a sliding groove is provided on the C-shaped arm, the mounting post passes through the sliding groove, and the mounting post can be slidably adjusted in the sliding groove, a limit plate is fixed on the outer wall of the mounting post, and an external thread is provided on the outer surface of the mounting post, and a fastening internal thread sleeve is screwed onto the outer surface of the mounting post through the external thread, the diameter of the limit plate and the width of the fastening internal thread sleeve are both larger than the width of the sliding groove, and when the fastening internal thread sleeve is tightened, the fastening internal thread sleeve and the limit plate can be clamped on both sides of the C-shaped arm to achieve fixation of the mounting post.
[0013] By loosening the fastening internal threaded sleeve and canceling the clamping of the C-arm, the entire mounting column can be slidably adjusted in the sliding groove, thereby facilitating fine-tuning the position of the pressure plate according to the specific puncture point. After the adjustment is completed, the fastening internal threaded sleeve is tightened to fasten the mounting column to the C-arm, so that the pressure plate can be aligned with the puncture point, providing effective compression force, thereby improving the versatility of the compression hemostasis device.
[0014] Furthermore, the outer peripheral surface of the fastening internal threaded sleeve is evenly distributed with planar gripping portions, and the gripping portions are evenly distributed with anti-slip grooves.
[0015] By pinching the holding part, it is convenient to exert force to screw and adjust the tightening internal threaded sleeve. In addition, anti-slip grooves are provided on the holding part to increase the friction between the fingers and the holding part, thereby avoiding slipping and falling out of the hand when screwing.
[0016] Furthermore, a first silicone pad is fixed on the inner edge wall of the C-shaped arm, and a second silicone pad is fixed on the surface of the pressure plate used for compression.
[0017] By arranging a first silicone pad on the inner edge wall of the C-arm and a second silicone pad on the pressure plate, a buffering and protective effect can be achieved. In addition, the first silicone pad and the second silicone pad are soft and skin-friendly, which further increases the comfort of the patient's wrist.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.
[0019] 1. The compression hemostasis device provided by the utility model can provide compression force to the puncture site of the patient's wrist through the clamping effect provided by the pressure plate and the end of the C-shaped arm away from the mounting column, thereby achieving a hemostatic effect. Compared with the traditional hemostasis method of tightening with a strap, the compression hemostasis device provided by the utility model adopts a two-point clamping method, which will not cause excessive tightening of the entire wrist, thereby will not affect the blood circulation in the wrist, avoid local swelling and pain, and improve the patient's comfort.
[0020] 2. The cross-sections of the sliding cavity and the telescopic rod of the utility model are respectively in mutually matching rectangular shapes, which play a guiding and limiting role, preventing the telescopic rod from rotating in the sliding cavity. Combined with the rotational connection between the threaded rod and the telescopic rod, it can be avoided that the threaded rod drives the telescopic rod to rotate synchronously when rotating, thereby preventing the pressure plate from rotating when contacting the hemostatic cotton, causing the hemostatic cotton and the puncture point to be misaligned, thereby affecting the compression and hemostasis effect.
[0021] 3. The utility model loosens the fastening internal threaded sleeve and cancels the clamping of the C-shaped arm, so that the entire mounting column can be slidably adjusted in the sliding groove, thereby facilitating fine-tuning the position of the pressure plate according to the specific puncture point. After the adjustment is completed, the fastening internal threaded sleeve is tightened to fasten the mounting column to the C-shaped arm, so that the pressure plate can be aligned with the puncture point, providing effective compression force, thereby improving the versatility of the compression hemostasis device.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-Figure 4 The utility model provides a compression hemostasis device for post-operative radial artery puncture, comprising a C-shaped arm 1, a mounting column 2 being provided at one end of the C-shaped arm 1, the mounting column 2 passing through the C-shaped arm 1, a pressure plate 3 being provided at the end of the mounting column 2, and an adjustment mechanism 4 being provided on the mounting column 2, the adjustment mechanism 4 being used to drive the pressure plate 3 to adjust along the length direction of the mounting column 2 to provide compression force.
[0029] When hemostasis is required after radial artery puncture, the hemostatic cotton is placed at the puncture site of the patient's wrist, and then the C-arm 1 is clamped on the wrist, and the pressure plate 3 is ensured to be aligned with the hemostatic cotton. Then, by operating the adjustment mechanism 4, the pressure plate 3 is pushed to move downward along the length direction of the mounting column 2. Combined with the support effect provided by the end of the C-arm 1 away from the mounting column 2, the pressure plate 3 can press the hemostatic cotton against the puncture site of the patient's wrist to achieve a compression hemostasis effect. The compression hemostasis device provided by the utility model can provide compression force to the puncture site of the patient's wrist through the clamping effect provided by the pressure plate 3 and the end of the C-arm 1 away from the mounting column 2, thereby achieving a hemostasis effect. Compared with the traditional hemostasis method of tightening with a strap, the compression hemostasis device is a two-point clamping method, which will not cause excessive tightening of the entire wrist, and thus will not affect the blood circulation at the wrist, avoid the phenomenon of local swelling and pain, and improve the comfort of the patient.
[0030] Specifically, the top of the mounting post 2 is provided with a threaded hole 401 extending downward, and the bottom of the mounting post 2 is provided with a sliding cavity 402 extending upward and penetrating with the threaded hole 401. The adjustment mechanism 4 includes a threaded rod 41 and a telescopic rod 42. The telescopic rod 42 is vertically slidably installed in the sliding cavity 402, and the bottom end extends to the bottom of the mounting post 2. The pressure plate 3 is fixed to the bottom end of the telescopic rod 42. The threaded rod 41 is screwed into the threaded hole 401 with matching threads. The bottom end of the threaded rod 41 extends into the sliding cavity 402 and is connected to the telescopic rod 42. The top end of the retractable rod 42 is rotatably connected, and the top end of the telescopic rod 42 extends to the top of the mounting column 2 and is provided with a pinching handle 43. By pinching the pinching handle 43 and exerting force to screw the threaded rod 41, the threaded rod 41 rotates and engages with the threaded hole 401, which can drive the telescopic rod 42 to slide downward, thereby pushing the pressure plate 3 downward to achieve a compression effect. By pinching the pinching handle 43 and screwing the threaded rod 41 in the opposite direction, the telescopic rod 42 and the pressure plate 3 can be driven to move upward, thereby canceling the compression force and facilitating the removal of the device from the patient's wrist.
[0031] Specifically, the cross-section of the sliding cavity 402 is rectangular, and the cross-section of the telescopic rod 42 is rectangular that is adapted to the sliding cavity 402. The cross-sections of the sliding cavity 402 and the telescopic rod 42 are respectively rectangular that match each other, which plays a guiding and limiting effect, preventing the telescopic rod 42 from rotating in the sliding cavity 402. Combined with the rotational connection between the threaded rod 41 and the telescopic rod 42, the threaded rod 41 can be prevented from driving the telescopic rod 42 to rotate synchronously when rotating, thereby preventing the pressure plate 3 from rotating when contacting the hemostatic cotton, causing the hemostatic cotton and the puncture point to be misaligned, thereby affecting the compression and hemostasis effect.
[0032] Specifically, a sliding groove 11 is provided on the C-shaped arm 1, and the mounting column 2 passes through the sliding groove 11, and the mounting column 2 can be slidably adjusted in the sliding groove 11. The two ends of the C-shaped arm 1 are of different lengths, and one end of the mounting column 2 is shorter than the other end. A limiting plate 21 is fixed on the outer wall of the mounting column 2, and an external thread 22 is provided on the outer surface of the mounting column 2. A fastening internal thread sleeve 23 is screwed on the outer surface of the mounting column 2 through the external thread 22. The diameter of the limiting plate 21 and the width of the fastening internal thread sleeve 23 are both larger than the width of the sliding groove 11. When the fastening internal thread sleeve 23 is screwed When tightened, the fastening internal threaded sleeve 23 and the limit plate 21 can be clamped on both sides of the C-shaped arm 1 to fix the mounting column 2. By loosening the fastening internal threaded sleeve 23 and canceling the clamping of the C-shaped arm 1, the mounting column 2 can be slid and adjusted as a whole in the sliding groove 11, so as to facilitate fine-tuning the position of the pressure plate 3 according to the specific puncture point. After the adjustment is completed, the fastening internal threaded sleeve 23 is tightened to fasten the mounting column 2 to the C-shaped arm 1, so that the pressure plate 3 can be aligned with the puncture point, providing effective compression force, thereby improving the versatility of the present compression hemostasis device.
[0033] Specifically, the outer circumferential surface of the fastening internal threaded sleeve 23 is evenly distributed with a planar pinching portion 231, and the pinching portion 231 is evenly distributed with an anti-slip pattern 232. By pinching the pinching portion 231, it is convenient to exert force to screw and adjust the fastening internal threaded sleeve 23. In addition, the anti-slip pattern 232 is provided on the pinching portion 231, which can increase the friction between the fingers and the pinching portion 231, thereby avoiding slipping and losing the hand during screwing.
[0034] Specifically, a first silicone pad 01 is fixed on the inner edge wall of the C-shaped arm 1, and a second silicone pad 02 is fixed on the surface of the pressure plate 3 for compression. By arranging the first silicone pad 01 on the inner edge wall of the C-shaped arm 1 and the second silicone pad 02 on the pressure plate 3, a buffering and protective effect can be achieved. In addition, the first silicone pad 01 and the second silicone pad 02 are soft and skin-friendly, which further increases the comfort of the patient's wrist.
